Description

Technical Field

[0001] The invention relates to a wall assembly type dry hanging construction device and method. Background Art

[0002] Wall decoration is an indispensable part of modern urban construction. Installing thermal insulation materials on the wall is for long-term energy conservation and environmental protection. Wall decoration is not only for the beauty of the city, but also can better protect the main body of the building from thermal expansion and freezing and thawing, and extend the service life of the building. Wall dry hanging construction has been a common construction method for building wall decoration for many years. There are cases in office buildings, commercial buildings, residential buildings, hotels and other buildings. Stone and tile dry hanging is a cost-effective, beautiful and durable wall decoration construction method. It can effectively solve the current safety problems of hollow brick walls and wall decoration after the construction of wall insulation materials, and effectively solve the problems of cracking, shedding, leakage, cold bridges, fire prevention and other problems of thermal insulation exterior decoration materials. Paint and real stone paint are easy to crack, shedding, leak, cold bridges on thermal insulation materials. They are not durable and cannot prevent the main body of the building from thermal expansion and freezing and thawing for a long time. However, the existing stone and tile dry hanging process has the following shortcomings:

[0003] 1. Traditional stone and ceramic tile dry hanging adopts T-shaped point hanging method and back bolt point hanging method. This method results in a small bearing surface of wall tiles and hangers, and the safety cannot keep up with the needs of urban construction. Because it adopts point bearing, the thickness of stone is generally required to be more than 25 mm, and the dead weight is very heavy. The corresponding keel requires a large amount of steel, resulting in high overall construction costs.

[0004] 2. Traditional dry-hanging keels are welded using high-temperature electric welding, which poses a fire hazard in the construction environment, and there are also safety accidents caused by oxidation and cracking of welding points.

[0005] 3. Traditional dry hanging of stone and ceramic tiles basically involves cutting hanging grooves at the construction site, which causes noise and dust pollution to the environment, is not environmentally friendly, and can easily cause on-site installation workers to suffer from occupational diseases such as pneumoconiosis.

[0006] 4. The traditional dry-hanging process of stone and tiles does not have a backing net. Since they all adopt the point-type hanging method, the backing net has no fixed place. Once it is subjected to external force or strong wind, it is easy to cause the stone to crack or fall off, causing casualties to pedestrians and property, causing losses.

[0007] 5. The traditional dry hanging construction process requires that the fixings need to be fastened behind the stone and tile, so it is required to be far away from the wall, the cost of the keel material is high, and there is no position for fixing the safety back net on the keel, so it cannot provide double safety insurance. If it is an indoor dry hanging, it is easy to waste space; it is also difficult to replace safely, and it is inevitable to damage the constructed stone and tile during cross-construction on the construction site.

[0008] 6. Large-scale stone mining damages the ecological environment and is not environmentally friendly. Summary of the invention

[0019] A wall assembly dry hanging construction method comprises the following steps:

[0020] 1) Fix the hanging groove keel:

[0021] a. According to the size of the wall material to be hung, determine the corresponding position of the live bolt, and drill holes on the two shoulders of the hanging groove keel. The holes are corresponding to the screw rods in one square and one circle.

[0022] b. Determine the position of the embedded plate and the hanging groove keel, the size and quantity of the embedded plate according to the size and specifications of the wall material to be hung, and drill bolt fixing holes at the corresponding positions of the embedded plate on the concrete beam, column or load-bearing wall;

[0023] c. Use expansion bolts and chemical bolts to fix the embedded plate on load-bearing concrete beams and columns, or on load-bearing walls;

[0024] d. Vertically weld the hanging groove keel to the embedded plate, so that the two shoulders of the hanging groove face outward and are perpendicular to the wall surface;

[0025] 2) Install the live bolts and L-shaped hangers:

[0026] a. Determine the number of brick hanging parts and supporting parts according to the specifications and dimensions of the wall materials, insert the brick hanging parts and supporting parts into the corresponding dovetail grooves and T-slots on the hanging beams, and then seal the ends of the hanging beams to prevent the brick hanging parts and supporting parts from slipping off;

[0027] b. Place the vertical plate of the L-shaped hanger against the hanging groove keel, insert the screw of the movable bolt into the square hole of one shoulder of the hanging groove keel, sleeve the movable rod on the screw, and then pass the screw through the other shoulder of the hanging groove keel and connect with the nut. Adjust the relative position of the hanging groove keel and the L-shaped hanger, and then screw the screw into the threaded hole of the rectangular parallelepiped. The end of the screw is against the vertical plate of the L-shaped hanger, so that the L-shaped hanger is pressed against the hanging groove keel, and the hanging beam is placed at the position required by the construction. Finally, adjust the position of the L-shaped hanger through the movable rod to ensure that the hanging beam is straight, and fix the bottom plate of the L-shaped hanger with the nut;

[0028] c. Use bolts and anti-skid pads to fix the fixing plate of the hanging beam to the bottom plate of the L-shaped hanging piece, and weld the L-shaped hanging piece to the hanging groove keel;

[0029] d. Install the remaining hanging beams at equal intervals according to the above steps;

[0030] e. Adjust the position of the brick hanging parts according to the hanging groove position of the wall material;

[0031] 3) Install wall materials:

[0032] Install the bottom hanging groove of the wall material on the brick hanging piece, the whole wall material is supported by the support plate of the hanging beam, the top hanging groove of the wall material is installed on the brick hanging piece under the support plate of the upper row of hanging beams of the brick hanging piece, fix the part of the safety net on the top of the excess wall material to the installation hole of the hanging beam fixing plate, and the wall material is bonded and fixed to the hanging beam by structural adhesive;

[0033] 4) After installing the wall material, paste anti-fouling paper on the edge of the wall material surface, use weather-resistant sealant to fill the gaps between the wall materials, and clean up the excess anti-fouling paper and glue after the weather-resistant sealant dries.

[0034] The nut described in step 2) and the part that cooperates with it are fixed by cold welding, and the part connected to the dovetail groove is fixed by structural adhesive.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1 The present invention adopts a strip top plate support hanging method, which can support the wall material safely and effectively for a long time, and the backs of the upper and lower ends of the wall material are bonded to the dovetail groove of the hanging beam with structural adhesive, which produces a stronger bonding force with the dovetail groove on the hanging beam, and the two ends of the wall material are hooked by the hanging brick piece with the dovetail groove, which effectively enhances the bonding performance between the wall material and the hanging beam.

[0037] 2 The present invention makes full use of the welding process combining electric welding and low-temperature cold welding according to the construction environment to ensure that the construction is firm and reliable, and to achieve safe fireproof construction. The present invention uses live bolts to double-reinforce the load-bearing L-shaped hanger, which greatly enhances the safety performance and realizes the "double insurance" of long-term safe use. By adjusting the screws and nuts of the live bolts, the position of the hanging beam can be quickly and accurately leveled and fixed. The process of first adjusting and fixing with bolts and then welding provides conditions for factory processing of wall materials, improves construction efficiency, and reduces the cost of dry hanging construction.

[0038] 3. All the wall material grooving and cutting of the present invention are completed in the factory with a water saw, and the back mesh pasting of the wall material is processed on a factory assembly line with environmental protection supporting protection facilities, which will not cause pollution to the environment, is more environmentally friendly, and will not cause "pneumoconiosis" occupational disease harm to the construction workers.

[0039] 4. The safety net is a double-layer net composed of anti-oxidation metal net and high-strength fiber net. It is bonded to the back of the wall material with structural adhesive, and the safety net is fixed to the hanging beam, which fully guarantees the safety and durability of the exterior wall material and effectively improves the wall material's ability to cope with severe weather and earthquake resistance.

[0040] 5 The hanging beam design of the present invention allows the brick hanging parts to independently fix each wall material at the upper and lower ends of the wall material, which is convenient for construction operation, greatly shortens the distance from the wall, saves keel materials, reduces costs, enhances the safety factor, and facilitates the replacement construction of single-piece exterior wall materials, reducing the entire dry hanging construction cost.

[0041] 6. Since the wall decoration materials of the present invention are all stressed on a solid keel frame and not directly stressed on the thermal insulation materials, it can effectively solve the current safety problems of wall decoration after the construction of hollow brick walls and wall thermal insulation materials, and effectively solve the problems of cracking, shedding, water leakage, cold bridges, fire prevention, etc. of the thermal insulation outer decorative materials.

[0042] 7 The wall materials used in the present invention are mainly ceramic tiles and rock slabs. Because of the double-layer back mesh and the ceramic slabs, the density and strength of the rock slabs are higher than those of natural stones. Generally, the material thickness is required to be more than 10 mm. The material has a light weight, which saves material costs and keel material costs, and reduces the overall construction cost.

[0043] 8 The ceramic tiles, rock slabs and supporting materials used in the present invention have no radioactive hazards, meet national environmental protection requirements, better improve the grade of building decoration and the safety of urban building walls, and enhance the weather resistance and service life of the main structure of the house.
