Description

Technical Field

[0001] The invention belongs to the technical field of building construction, in particular to a construction method for stone curtain walls and water dispersion nodes. Background Art

[0002] In modern architecture, stone curtain walls are widely used in high-rise buildings and commercial facilities due to their elegant appearance and excellent physical properties. However, with the continuous development of architectural design, the construction technology of stone curtain walls also faces many challenges, especially in terms of waterproof performance, structural stability and aesthetics.

[0003] The existing water dispersion design is often not flexible enough to effectively guide rainwater out, resulting in water accumulation on the building exterior wall, which in turn causes leakage and water vapor damage. The joint treatment of stone curtain walls is also often not strict enough, and the selection or construction method of sealants and filling materials is improper, making the joints a weak link for water infiltration.

[0004] Secondly, the supporting structure design of stone curtain walls is often not perfect, especially when dealing with external pressures such as wind pressure and gravity, and lacks sufficient stability. Many construction plans fail to fully consider the weight of the stone and the impact of the external environment on the curtain wall, resulting in the risk of deformation, cracking or falling off of the curtain wall under extreme conditions such as strong winds or earthquakes. In addition, traditional cushion treatment methods often ignore the importance of compaction and leveling, resulting in an unstable stone foundation and increasing the difficulty and cost of subsequent maintenance.

[0005] The existing technology also has shortcomings in the treatment and maintenance of stone surfaces. Problems such as poor appearance and insufficient glossiness of the stone surface after construction often occur, which not only affects the aesthetics of the building, but also reduces the durability of the stone. At the same time, due to the lack of detailed waterproofing measures and sealing treatment, the cost and time cost of maintenance in the future will also be relatively high.

[0006] To this end, technicians in this field have proposed a construction method for stone curtain walls and scattered water nodes, aiming to improve the overall performance and economy of stone curtain walls and meet the high requirements of modern buildings for safety, durability and aesthetics. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a construction method for a stone curtain wall and a water dispersion node to solve the problems raised in the background technology.

[0008] A construction method for a stone curtain wall and a water dispersion node comprises the following steps:

[0009] S1. Construction preparation: measure the actual dimensions of the wall, cornice and columns, mark the axis, column line and column spacing, determine the installation position and size of the stone curtain wall, and draw the block diagram and node diagram;

[0010] S2. Treatment of water dispersal nodes: clean the foundation surface at the water dispersal node location, set up a lime soil cushion layer, compact it to the designed dry density, set up the formwork, pour concrete, and perform surface polishing and maintenance;

[0011] S3. Stone curtain wall installation: according to the design drawings, use a laser vertical meter to lay out the curtain wall installation control line, and install the adapter according to the position of the embedded parts, and debug its elevation and position; then install the supporting structure, install the hanging parts and install the stone;

[0012] S4, Node sealing treatment: Use a cutting machine to trim the stone joints, clean the debris in the board joints, and stick tape; fill the polystyrene foam rods, and use a glue gun to inject silicone sealant into the gaps. After the sealant surface is dry, remove the tape;

[0013] S5. Cleaning and acceptance: Clean the construction site to ensure that there is no dirt left on the stone curtain wall and scattered water nodes, and conduct a comprehensive acceptance of the stone curtain wall and scattered water nodes.

[0014] Preferably, in the step S2, when treating the water dispersing nodes, cement, sand and water are mixed to form lime soil, which is evenly spread on the cleaned foundation surface, and the lime soil is preliminarily leveled using a leveler or a scraper, and the lime soil cushion layer is compacted to the designed dry density using a 3:7 soil cushion layer;

[0015] When supporting the formwork, use wooden boards or steel formwork as the formwork material. Support the side formwork according to the external dimensions of the splashback, place the partition formwork, and use a wood planer to smooth both sides of the partition formwork. When supporting, draw a line and level it, and slope it outward by 4%. The partition joint is 20mm wide and is set along the outer wall. A partition joint is set every 6m in the longitudinal direction, and the corners of the house are at a 45-degree angle to the outer wall.

[0016] Preferably, in the step S2, when treating the water dispersing node, cement, sand, gravel and water are mixed to prepare concrete, concrete is poured evenly from one end to make the concrete flow evenly, and a vibrator is used to preliminarily vibrate the concrete to eliminate bubbles so that the concrete is combined with the base;

[0017] Use a calender to calender the upper concrete surface so that the concrete surface of the diffuser node has a slope of 1%-2%. The concrete should be cured immediately after pouring. Cover it with plastic film, wet sacks or spray curing agent to keep it moist. Continue curing for 7 days.

[0018] Preferably, when installing the stone curtain wall in step S3, an external control line is released on the bottom floor of the building, its horizontal elevation point is determined, the installation control line of the curtain wall is determined, and then the control point is led to the top floor of the standard layer by a laser vertical meter for positioning. During positioning, a fixed fulcrum is set for every 2 layers of the vertical steel wire, and a fixed fulcrum is set for every 4 meters of the horizontal steel wire;

[0019] According to the position of the embedded parts, fix the adapter to the embedded parts with stainless steel screws, use a level or laser to check the horizontality and verticality of the adapter, so that the elevation and the front, back, left and right deviations of the adapter do not exceed the specified range. If exceeded, adjust the adapter so that it is at the designed elevation and fix it after adjustment.

[0020] Preferably, when installing the stone curtain wall in step S3, the supporting structure is placed on the wall according to the position of the control line and the adapter, so that it is correctly connected with the adapter, and the supporting structure is fixed to the wall and the adapter by bolts or welding; the supporting structure includes a steel pipe column and a channel steel beam, and after the connecting piece is connected to the steel pipe column, it is adjusted to the installation position for installation, and after the steel pipe column is installed, the channel steel beam is installed and bolted to the steel pipe column, and its size and steel wire are checked during installation to ensure that the deviation of its size and axis does not exceed the specified range;

[0021] Mark the installation position of the hangers on the supporting structure, determine the height and spacing of each hanger, fix the hangers on the angle steel with bolts, connect the steel hangers and the angle steel with rubber gaskets, and then adjust the elevation and left and right according to the control line;

[0022] Before installing the stone, the stone is treated with waterproof and anti-fouling treatment. During the installation process, the stone is tried out and its installation angle is adjusted. The stone is hung according to the vertical steel wire and the horizontal fish wire, and waterproof material or sealant is applied to the contact surface and gap between the stone and the hanger. After the stone at the corner and the connection with the glass curtain wall is installed, the stone is laid over a large area and the gaps between the stones are filled with silicone sealant.

[0023] Preferably, during the node sealing treatment in step S4, a cutting machine is used to trim the stone joints, the cutting is performed along the original joints to make the joints neat, and a vacuum cleaner is used to clean the dust and debris around the stone joints;

[0024] Use a brush and a spatula to thoroughly clean the dust and debris in the joints, and use a compressed air blow gun to blow away the residue in the joints to make the inside of the joints dry;

[0025] Stick tape on both sides of each stone joint, making the tape edges neat and close to the stone surface to form a sealed area to prevent silicone sealant from overflowing when filling the joints, making the area around the joints neat;

[0026] Measure the length of the polystyrene foam rod according to the width of the joint, cut the foam rod, and gently press the foam rod into the joint to fill it tightly and set it to the middle of the depth of the joint;

[0027] Insert the tube of silicone sealant into the glue gun, use the glue gun to evenly inject silicone sealant from one end of the joint, fill the joint and make it contact with the foam rod, use a scraper or your fingers to gently smooth the surface of the sealant and make it flush with the stone surface;

[0028] After 24 hours of curing, when the silicone sealant surface is dry, check whether it is completely cured and gently lift the tape from one end to make the seam neat without tearing the edge of the sealant.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention can effectively guide rainwater to drain out, reduce water accumulation, prevent leakage and water vapor damage through flexible water dispersion design, combined with the cushion layer and joint sealing treatment of the stone curtain wall, and use sealant and polystyrene foam rods to enhance the waterproofness of the joints and reduce the risk of water infiltration into the curtain wall.

[0031] 2.

[0034] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] As attached Figure 1 As shown:

[0036] Embodiment: The present invention provides a construction method for a stone curtain wall and a water dispersion node, comprising the following steps:

[0037] S1. Construction preparation: measure the actual dimensions of the wall, cornice and column, mark the axis, column line and column spacing, and determine the installation position and size of the stone curtain wall. Determine the start and end positions of the stone curtain wall through the architectural design drawings, confirm the gap between the edge of the curtain wall and the wall, cornice and column, calculate the size of each block of the stone curtain wall based on the actual measurement results of the wall and column, and draw the block diagram and node diagram;

[0038] S2. Treatment of scattered water nodes: clean the foundation surface at the scattered water node location, set up a gray soil cushion layer, and compact it to the designed dry density. At the same time, set up the formwork, pour concrete, and perform surface polishing and maintenance. If there is old concrete, bricks or other materials, remove them first to ensure that they are clean, and remove dust, debris and oil stains at the node location to ensure that the foundation surface is clean and provide a good bonding foundation. Then mix cement, sand and water to make gray soil, and evenly spread the gray soil on the cleaned foundation surface with a thickness of 5-10 cm. Use a leveler or scraper to perform preliminary leveling on the gray soil to ensure that its surface is smooth and dense. The gray soil cushion layer is compacted to the designed dry density with a 3:7 secondary soil cushion layer, where 3:7 refers to the ratio of gray soil to soil, that is, gray soil accounts for 30%, and the remaining 70% is soil. The secondary soil cushion layer refers to the soil that has been compacted and leveled for the first time as the foundation, and then the second soil cushion layer is compacted. Compact by layer, keep each layer uniform, and ensure that the cushion layer reaches the designed dry density.

[0039] When supporting the formwork, use wooden boards or steel formwork as the formwork material. Support the side formwork according to the external dimensions of the splashback, place the partition formwork, and use a wood planer to smooth both sides of the partition formwork. When supporting, draw a line and level it, and slope it outward by 4%. The partition joint is 20mm wide and is set along the outer wall. A partition joint is set every 6m in the longitudinal direction, and the corners of the house are at a 45-degree angle to the outer wall.

[0040] Mix cement, sand, gravel and water to prepare concrete, pour concrete evenly from one end to make the concrete flow evenly, avoid pouring concrete from high altitude to reduce water seepage and affect strength; and use a vibrator to initially vibrate the concrete to eliminate bubbles and allow the concrete to bond with the base;

[0041] Use a calender to calender the upper concrete surface to ensure it is flat and smooth to prevent cracks in the later stage. Make the concrete surface of the drainage node have a slope of 1% to 2% to ensure that rainwater can be discharged smoothly. And after the concrete is poured, it should be cured immediately. Cover it with plastic film, wet sacks or spray curing agent to keep it moist to avoid its surface cracking. Continue curing for 7 days.

When positioning, set a fixed support point every 2 floors for the vertical steel wire and a fixed support point every 4 meters for the horizontal steel wire;

[0043] According to the position of the embedded parts, fix the adapter to the embedded parts with stainless steel screws, use a level or laser to check the horizontality and verticality of the adapter, so that the elevation and the front, back, left and right deviations of the adapter do not exceed the specified range. If exceeded, adjust the adapter so that it is at the designed elevation and fix it after adjustment.

[0044] According to the position of the control line and the adapter, place the support structure on the wall, connect it with the adapter correctly, and fix the support structure to the wall and the adapter by bolts or welding; the support structure includes steel pipe columns and channel steel beams. After connecting the connectors to the steel pipe columns, move them to the installation position for installation. After the steel pipe columns are installed, install the channel steel beams and bolt them to the steel pipe columns. During installation, check their dimensions and steel wires to ensure that the deviation of their dimensions and axis does not exceed the specified range;
