The dry-hang stone drawing window closing construction plan is one of the key links in construction, especially in high-end buildings and decoration projects. The closing process around the window is not only related to the appearance, but also directly affects the structural stability and waterproof performance of the building. This plan introduces in detail the material requirements, construction methods, quality standards, safety measures and environmental protection measures for window closing in Dry-hang stone construction, ensuring that the entire construction process strictly complies with the standards and achieves high-quality construction results. The following is a detailed expansion of the content.
Dry-hang Stone Materials Needed
Cement: The employed cement has to satisfy the PC32.5 grade ordinary Portland cement standard. The cement should be rigorously checked for quality before entering the site, including tests of strength, setting time and stability, thereby guaranteeing that its quality satisfies the criteria. Particularly, the cement must be retested and used in line with the test findings when it is kept for more than three months. Simultaneously, several forms of cement should not be used to prevent needless quality issues.
Sand: This project has to be screened and uses medium sand with a particle size of 0.35 to 0.5mm. Sand must not contain clay or other contaminants; every sand needs to pass through a sieve with a 5mm opening to eliminate impurities thereby ensuring that the sand particles are firm and clean. The quality of sand directly influences the bonding and durability of cement mortar, hence the needs for sand are especially rigorous.
Water: To guarantee that the water quality satisfies building criteria, the water source should make advantage of on-site tap water. very in some high-strength building needs, the quality of water directly influences the quality of cement mortar; so, the purity of water quality is very crucial.
Construction glue: The construction glue used in this project must be a high-strength product, such 108 glue, to guarantee that it can supply enough bonding force at the window closing joints. The wire mesh has specs of 10mm by 10mm by 0.8mm; nails are used to fix it, etc. The whole quality of the finishing project depends on the glue and accessories chosen.
Autoclaved lime sand brick: The 240x115x53mm size of the autoclaved lime sand brick makes it necessary for strong strength and stability to guarantee the stability of the whole structure following construction. It is used to fill bigger gaps or fill partial regions.
Dry-hang Stone Construction Conditions
The foundation of the process of Dry-hang stone building is the acceptance of the primary structure. The construction unit, the quality supervision and design unit, and each other must all agree this acceptance and make sure it has passed. Unless it is proven that the main structure meets the criteria of the design and the quality standards, the next building activity will not be done. Particularly while performing activities like dry-hang stone and plastering, the acceptance of the main structure is the basic condition that must be fulfilled to ensure the smooth flow of the next building. Should structural problems arise that deviate from standards, it is likely that the quality and advancement of the next construction would suffer.
Furthermore, the building of dry-hang stone is a quite important link, especially in the construction of dry-hang stone around the windows, which has to be completed before plastering can start. This can both guarantee that the Dry-hang stone and the plastering layer are a good mix and essentially stop interference with the plastering work that will be done later on during the construction process. If the stone dry hanging construction is done following the plastering process, it is not only easy to cause the joints between the stone and the mortar to become loose, but it also easy to produce damage to the material or insufficient bonding of the material due of the influence of the humid environment on the stone. Therefore, the construction of dry hanging stone must be closely in compliance with the particular sequence of the procedure and coordinated with the plastering work that will be executed later.
An important element that needs to be finished before plastering is base preparation. Starting with cleaning the concrete dry-hang stone wall helps to remove any contaminants, dust, oil stains, and other elements that might be on surface. This will ensure the wall is smooth and clean, thereby enabling the mortar to adhere more successfully. The wall has to be roughened following cleaning if we are to increase the mortar’s bonding and endurance. In situations whereby the plaster’s thickness exceeds 35 mm, this is very crucial. The wall needs further wire mesh inserted. The great thickness of the plaster layer makes the wire mesh not only more supporting but also helps to stop the layer from fracturing and coming off. Once the wall has been treated, it needs to be sufficiently hydrated even now. This is essential to avoid the wall becoming too dry causing the mortar to crack early during construction, so compromising the quality of the structure.
One should also not undervalue the effort put in readiness for plastering. Before starting the official plastering process, one must arrange the suitable scaffolding. This is done to guarantee that the dry-hang stone wall and the scaffolding are twenty to twenty-five centimetre apart. This enables the construction workers to function in a convenient way, so guaranteeing their safety and efficiency all through the building process. Furthermore, the instruments used throughout the building procedure have to be totally ready. Among these instruments are plastering boards, trowels, mortar mixers, steel nails, and other such objects. Tool preparation directly affects the quality of construction as well as the efficiency of constructing. This is especially true in some complex plastering jobs, where the accuracy and appearance of the building can be much enhanced by the professionalism and suitability of the instruments.
Dry-hang Stone Construction Methods And Processes
Base cleaning is a very important first step before plastering. To get rid of the last mortar, oil, dust, and other trash on the surface, the wall needs to be completely cleaned. The foundation for guaranteeing strong bonding between the wall and the mortar is this procedure. Should the dry-hang stone wall be unclean, the bonding between the mortar and the wall would be significantly diminished, which would readily cause issues including hollowing of the plaster layer and shedding. Water must be used to moisten the wall once the cleaning is finished so as to prevent the mortar from drying too fast. The damp wall facilitates mortar bonding so that it may completely touch the wall and improve the firmness of the plaster layer.
Base treatment comes after the base is cleansed. Concrete dry-hang stone walls especially in relation to thick plastering must be roughened. Usually, Roughening treatment is sprayed using cement mortar combined with an interface agent. This technique can raise the mortar’s bonding strength and roughness of the wall surface. To prevent too long burrs compromising the flatness and durability of the plaster layer, the sprayed mortar should be homogeneous and the burr length should be limited at roughly 5mm, not more than 8mm. Roughening treatment serves to strengthen the link between mortar and foundation layer and guarantee the quality of next plastering construction.
The wall should be hung vertically following the completion of the base layer treatment to fit the square and locate the guidelines. This is a crucial stage to guarantee the plastering job satisfies design criteria. Tools include straightedges, tape measures, and level rulers are required to verify the verticality and horizontality of doors, windows, corners and other portions of the dry-hang stone wall to ensure that the wall remains flat, vertical and horizontal during the whole plastering process. This procedure guarantees that the resultant impact satisfies the design criteria by properly avoiding issues including tilting and deformation throughout the plastering process.
Building the plastering base ash comes next since it offers a strong basis for the next cover ash. The foundation ash can be plastered when the dry-hang stone wall is cleaned and treated. The base ash should be layered with 1:3 cement mortar for the section where the d value of the window is less than 50mm; each layer should be crushed and polished. Use a wooden trowel to compact the foundation mortar such that it is tightly mixed with the base layer and to rub the surface, therefore strengthening the bonding between the base mortar and the following plastering layer. Should the wall thickness be significant or the base mortar layer be thick, a wire mesh should also be utilized for reinforcement to avoid thinning of the thick mortar or cracking.
Autoclaved sand-lime bricks can be used for mending some bigger gaps where the base mortar cannot be straight filled. To guarantee the firmness of the patching area, firmly masonry the sand-lime bricks using high-strength mortar. Following the masonry is finished, it is essential to wait until the mortar strength reaches 60% dry before starting further plastering operations, therefore preventing the freshly constructed dry-hang stone wall from compromising the quality of the plastering layer by insufficient solidification.
The topcoat is built upon the completion of the foundation mortar construction and somewhat dried state. Usually plastered in two passes, the topcoat employs 1:2 cement mortar. Scrape the thin mortar first to improve the bonding strength of the mortar and establish a basis for the second thick layer. To guarantee a smooth and consistent surface, compact and level the finishing ash with a trowel the second times. If the base ash is too dry during the finishing ash building, you can wet it suitably to prevent inadequate adhesion between the mortar and the base ash layer, therefore avoiding difficulties including the fall-off, cracking, and other effects. Following the completion of the finishing ash construction will significantly enhance the thickness and surface quality of the whole plaster layer, thereby producing a smooth and seamless look.
Once the plastering process is finished, maintenance has to be done to guarantee that the mortar may be completely consolidated to prevent hollows or fractures resulting from too quick water evaporation. Usually at room temperature, the curing process is done; so, the curing duration should be least 24 hours. Water spraying from a sprayer will help to maintain the dry-hang stone wall moist and prevent mortar crumbling during this period. By means of constant weting, the strength of the mortar can be progressively raised, therefore guaranteeing the endurance and stability of the plaster layer.
