Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly relates to an integrated earthquake-resistant and heat-insulating exterior shear wall and a construction method thereof. Background Art

[0002] The shear wall structure system has always occupied an important position in the construction market of our country. It is widely recognized in the market for its dual use as a structural wall and a partition wall in residential buildings, as well as the characteristics of no exposed beams and columns.

[0003] At present, in the seismic design of buildings, shear walls are one of the most important structural elements. Shear walls provide sufficient stiffness and strength to resist horizontal seismic forces and prevent excessive deformation or collapse of buildings. Different types of seismic waves (such as longitudinal waves, transverse waves, etc.) act on building shear walls in different ways, resulting in different stress conditions. For example, transverse waves generate transverse shear forces on buildings, while longitudinal waves cause shear walls to experience deformation in the up and down directions. For existing shear wall structures, more emphasis is placed on resisting horizontal seismic forces, such as shear forces and bending moments, rather than on longitudinal compression and tension. The longitudinal pressure generated by longitudinal waves may not be fully and effectively absorbed and resisted by shear walls. Therefore, in the face of longitudinal waves, the bearing capacity of existing shear wall structures is limited, which may lead to uneven axial deformation or displacement of shear walls. Such deformation not only easily affects the structural stability of buildings, but also may cause the insulation materials on the surface of the exterior shear wall to fall off, resulting in the loss of insulation performance and posing certain safety hazards.

[0004] Therefore, it is very necessary to invent an integrated earthquake-resistant and heat-insulating exterior shear wall and a construction method thereof. Summary of the Invention

[0005] In order to achieve the above object, the present invention provides the following technical solution: An integrated earthquake-resistant and heat-insulating exterior shear wall, comprising a structural layer, a heat-insulating layer and a structural layer. The structural layer is set as the outer layer of the exterior shear wall, the structural layer is set as the inner layer of the exterior shear wall, the heat-insulating layer is set as the interlayer between the structural layer and the structural layer. Reinforcing bars are arranged inside the structural layer, a low-carbon steel wire mesh is arranged inside the structural layer. A connecting component is installed between the low-carbon steel wire mesh and the heat-insulating layer. Seismic pipe network structures are embedded on both sides of the heat-insulating layer. The seismic pipe network structure adopts a segmented structure. The seismic pipe network structure is used for lateral displacement along with the seismic transverse wave, and the seismic pipe network structure is also used for longitudinal compression along with the seismic longitudinal wave.

[0006] Preferably, the heat-insulating layer is made of extruded polystyrene. A number of longitudinal grooves are arranged horizontally at a certain interval on both surfaces of the heat-insulating layer. The longitudinal grooves on both sides of the heat-insulating layer are arranged staggeredly at intervals on the surface of the heat-insulating layer.

[0007] Preferably, the earthquake-resistant pipe network structure includes a steel wire pipe network base, which is a short tubular structure welded by steel wires. The steel wire pipe network base is embedded at the lower end of the longitudinal grooves on both sides of the insulation layer, and several steel wire pipe network frames are stacked on the upper end of the steel wire pipe network base.

[0008] Preferably, the steel wire pipe network frame is integrally a short tubular structure welded by steel wires. The steel wire pipe network frame is embedded in the longitudinal grooves on both sides of the insulation layer, and a network frame joint is installed at the lower end of the steel wire pipe network frame. The network frame joint is a tubular structure with the lower end welded by steel wires and inwardly contracted.

[0009] Preferably, the earthquake-resistant pipe network structure includes an arched network frame, which is a hemispherical arch top network frame structure welded by steel wires. The arched network frame is welded and installed on the upper side of the inner walls of the steel wire pipe network base and the steel wire pipe network frame. The arched network frame is not provided in the uppermost steel wire pipe network frame in the longitudinal grooves of the insulation layer.

[0010] Preferably, after removing the lowermost steel wire pipe network frame in the longitudinal grooves of the insulation layer, the network frame joints at the lower ends of the remaining steel wire pipe network frames are inserted downward into the upper ends of the adjacent steel wire pipe network frames and are in contact with the top surfaces of the arched network frames inside the adjacent steel wire pipe network frames. The network frame joints at the lower ends of the lowermost steel wire pipe network frames in the longitudinal grooves of the insulation layer are inserted downward into the adjacent steel wire pipe network bases and are in contact with the top surfaces of the arched network frames inside the steel wire pipe network bases.

[0011] Preferably, the structural layer is formed by concrete pouring. The low-carbon steel wire mesh is embedded in the center of the structural layer. The concrete during the pouring of the structural layer will fill the longitudinal grooves on the side of the insulation layer close to the structural layer.

[0012] Preferably, the connection assembly includes a connection base, one side of which is embedded and installed on the surface of the insulation layer close to the structural layer. A connection top piece is installed at the end of the connection base away from the insulation layer. The connection top piece and the connection base clamp both sides of the low-carbon steel wire mesh and are fixedly connected by bolts. A broken bridge waterproof cap is installed at the end of the connection top piece away from the connection base.

[0013] Preferably, the structural layer is formed by concrete pouring. Several steel bars cross and overlap to form a two-layer steel bar network frame and are embedded in the structural layer. The concrete during the pouring of the structural layer will fill the longitudinal grooves on the side of the insulation layer close to the structural layer.

[0014] The above-mentioned construction method of an earthquake-resistant and heat-insulating integrated external shear wall includes S1 - S4.

[0015] S1. First, the insulation layer is formed by co-extruding polystyrene resin with special additives at high temperature in the factory. The insulation layer is transported to the construction site and installed at the preset position. Subsequently, workers use an electric cutting knife or an electric grinding wheel to open longitudinal slots on both sides of the insulation layer. After that, the insulation layer needs to undergo a special insulation acceptance;

[0016] S2. After the insulation layer passes the special insulation acceptance, workers fill wire mesh pedestals at the lower ends of the longitudinal slots on both sides of the insulation layer. Then, wire mesh frames are successively stacked and installed on the upper ends of the wire mesh pedestals until the longitudinal slots on both sides of the insulation layer are filled. During installation, it is necessary to make the grid joints at the lower ends of each wire mesh frame insert downward into the wire mesh frame or wire mesh pedestal below and contact the arched grid top surface inside;

[0017] S3. Then, reinforce the steel bar grid on one side of the insulation layer with steel bars. Subsequently, make holes and insert connection bases on the other side of the insulation layer. Place the low-carbon steel wire mesh on one side of the connection base. Then, use bolts to connect the connection top piece with the connection base and clamp and fix the low-carbon steel wire mesh. Finally, install the broken bridge waterproof caps at the ends of the connection top pieces in sequence;

[0018] S4. First, install the formwork of the structural wall on the three sides of the low-carbon steel wire mesh away from the insulation layer. Then, install the formwork of the structural wall on the three sides of the steel bar grid away from the insulation layer. Before pouring concrete, insert the ~-type vibrating rod between the insulation layer and the wall formwork. Subsequently, pour in the concrete. It is advisable to adopt a push-type continuous pouring at the same pouring point. When switching between multiple pouring points, the next layer of concrete should be poured before the previous layer of concrete starts to set. As the concrete level rises, gradually pull out the vibrating rod. When the concrete is locally blocked, it can be rammed with steel bars. During concrete pouring, the height difference between the concrete levels on both sides of the insulation layer should not be greater than 400 mm. After the concrete on both sides of the insulation layer solidifies to form the structural layer and the structural layer, remove the formwork of the structural wall and the formwork of the structural wall. After the formwork is removed, maintenance measures should be immediately taken for the structural layer and the structural layer, and the maintenance time should not be less than 14 days.

[0019] The beneficial effects of the present invention are as follows: 1. By setting a segmented seismic pipe network structure inside the shear wall, when the shear wall is subjected to seismic transverse waves, each part of the seismic pipe network structure can displace horizontally with the seismic transverse waves, playing a buffering role, effectively reducing the horizontal shear force generated by the wall under the action of the transverse waves, and further strengthening the shear wall's ability to withstand seismic transverse waves;

[0020] 2. When the shear wall is subjected to seismic longitudinal waves, each part of the seismic pipe network structure can be compressed longitudinally with the seismic longitudinal waves, playing a buffering role, effectively alleviating the compressive force suffered by the wall under the action of the longitudinal waves, and greatly increasing the upper limit of the shear wall's ability to withstand seismic longitudinal waves;

[0021] 3. By pouring the construction layer and the structural layer on both sides of the insulation layer simultaneously, the insulation layer is integrated with the shear wall structure, which not only reduces the risk of the insulation layer falling off in the later stage but also effectively improves the overall fire resistance rating of the insulation layer. Further, the connection strength between the wire mesh in the construction layer and the insulation layer is enhanced through the connection components, which can effectively prevent the outer wall of the construction layer from falling off under the action of an earthquake.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0031] Example 1, as Figure 1 - Figure 6As shown in the figure, an earthquake-resistant and thermal-insulating integrated external shear wall in the first aspect embodiment of the present invention includes a structural layer 11, a thermal-insulating layer 12, and a structural layer 13. The structural layer 11 is set as the outer layer of the external shear wall, the structural layer 13 is set as the inner layer of the external shear wall, the thermal-insulating layer 12 is set as the interlayer between the structural layer 11 and the structural layer 13. Steel bars 14 are built in the structural layer 13, and a low-carbon steel wire mesh 15 is built in the structural layer 11. A connecting component is installed between the low-carbon steel wire mesh 15 and the thermal-insulating layer 12. Earthquake-resistant pipe network structures are embedded on both sides of the thermal-insulating layer 12. The earthquake-resistant pipe network structure adopts a segmented structure and is used for lateral displacement along with the horizontal seismic wave and also for longitudinal compression along with the vertical seismic wave.

[0032] In the above embodiment, it should be noted that by setting a segmented earthquake-resistant pipe network structure in the shear wall, when the shear wall is affected by the horizontal seismic wave, each part of the earthquake-resistant pipe network structure can laterally displace along with the horizontal seismic wave, playing a buffering role and effectively reducing the horizontal shear force generated by the action of the horizontal seismic wave on the wall, further strengthening the bearing capacity of the shear wall for the horizontal seismic wave; when the shear wall is affected by the vertical seismic wave, each part of the earthquake-resistant pipe network structure can longitudinally compress along with the vertical seismic wave, playing a buffering role and effectively alleviating the compressive force received by the wall under the action of the vertical seismic wave, greatly improving the upper limit of the bearing capacity of the shear wall for the vertical seismic wave.

[0033] By pouring the structural layer 11 and the structural layer 13 on both sides of the thermal-insulating layer 12 at the same time, the thermal-insulating layer 12 is integrated with the shear wall structure, which not only reduces the risk of the thermal-insulating layer 12 falling off in the later stage but also effectively improves the overall fire protection level of the thermal-insulating layer. Further, the connecting component strengthens the connection strength between the low-carbon steel wire mesh 15 in the structural layer and the thermal-insulating layer 12, and can effectively prevent the outer wall of the structural layer 11 from falling off under the action of an earthquake.

[0034] Embodiment 2, as Figure 2 、 Figure 4 、 Figure 5 and Figure 6 shown, an earthquake-resistant and thermal-insulating integrated external shear wall includes Embodiment 1. In addition, the thermal-insulating layer 12 is made of extruded polystyrene. A number of longitudinal grooves are arranged horizontally at a certain interval on both side surfaces of the thermal-insulating layer 12. The longitudinal grooves on both sides of the thermal-insulating layer 12 are arranged staggeredly at intervals on the surface of the thermal-insulating layer 12. The structural layer 11 is formed by concrete pouring. The low-carbon steel wire mesh 15 is embedded in the center of the structural layer 11. The concrete during the pouring of the structural layer 11 will fill the longitudinal grooves on the side of the thermal-insulating layer 12 close to the structural layer 11. The structural layer 13 is formed by concrete pouring. A number of steel bars 14 cross and overlap to form two layers of steel bar grids and are embedded in the structural layer 13. The concrete during the pouring of the structural layer 13 will fill the longitudinal grooves on the side of the thermal-insulating layer 12 close to the structural layer 13.

[0035] In the above embodiments, it should be noted that the extruded polystyrene used for the thermal insulation layer 12 is a closed-cell foam material formed by co-extruding polystyrene resin with special additives at high temperature. The longitudinal slots on both sides of the thermal insulation layer 12 are arranged staggeredly at intervals to avoid excessive reduction of the thickness of the thermal insulation layer 12 and prevent the decline of the thermal insulation performance of the thermal insulation layer 12; when the structural layer 11 and the structural layer 13 are poured, they will be embedded in the longitudinal slots on both sides of the thermal insulation layer 12, increasing the contact area between the structural layer 11 and the structural layer 13 and the thermal insulation layer 12, and greatly improving the connection strength.

[0036] Embodiment 3, as Figure 2 - Figure 7 shown, an earthquake-resistant and thermal insulation integrated external shear wall includes Embodiment 2. In addition, the earthquake-resistant pipe network structure includes a steel wire pipe network base 21, which is a short tubular structure welded by steel wires. The steel wire pipe network base 21 is embedded and installed at the lower end of the longitudinal slots on both sides of the thermal insulation layer 12. A number of steel wire pipe network frames 20 are stacked on the upper end of the steel wire pipe network base 21. The steel wire pipe network frame 20 is an overall short tubular structure welded by steel wires. The steel wire pipe network frame 20 is embedded in the longitudinal slots on both sides of the thermal insulation layer 12. A network frame joint 22 is installed at the lower end of the steel wire pipe network frame 20. The network frame joint 22 is a tubular structure with the lower end welded by steel wires and inwardly contracted. The earthquake-resistant pipe network structure includes an arched network frame 23, which is a hemispherical arch top network frame structure welded by steel wires. The arched network frame 23 is welded and installed on the upper side of the inner walls of the steel wire pipe network base 21 and the steel wire pipe network frame 20. The arched network frame 23 is not provided in the uppermost steel wire pipe network frame 20 in the longitudinal slots of the thermal insulation layer 12. After removing the lowermost steel wire pipe network frame 20 from the longitudinal slots of the thermal insulation layer 12, the network frame joints 22 at the lower ends of the remaining steel wire pipe network frames 20 are inserted downward into the upper ends of the adjacent steel wire pipe network frames 20 and are in contact with the top surfaces of the arched network frames 23 in the adjacent steel wire pipe network frames 20. The network frame joint 22 at the lower end of the lowermost steel wire pipe network frame 20 in the longitudinal slots of the thermal insulation layer 12 is inserted downward into the adjacent steel wire pipe network base 21 and is in contact with the top surface of the arched network frame 23 in the steel wire pipe network base 21.

[0037] In the above embodiments, it should be noted that the pipe diameter of the steel wire pipe network frame 20 is equal to the pipe diameter of the steel wire pipe network base 21, the diameter of the arched network frame 23 is equal to the inner diameter of the steel wire pipe network frame 20, the diameter of the lower end of the network frame joint 22 is smaller than the pipe diameter of the steel wire pipe network frame 20, and there is a gap between the outer side of the network frame joint 22 and the inner wall of the steel wire pipe network frame 20. When affected by the horizontal seismic wave, the network frame joint 22 will make a slight displacement in the steel wire pipe network frame 20 or the steel wire pipe network base 21 to play a role in buffering the shear force; the arched network frame 23 has a certain elasticity. When affected by the longitudinal seismic wave, the network frame joint 22 squeezes the arched network frame 23 downward, and the arched network frame 23 deforms and buffers the longitudinal compression force.

[0038] Embodiment 4, as Figure 2and Figure 3 As shown in Figure 3 , an integrated anti-seismic and thermal insulation external shear wall includes Embodiment 2. In addition, the connection component includes a connection base 17. One side of the connection base 17 is embedded and installed on the surface of the thermal insulation layer 12 close to the structure layer 11. One end of the connection base 17 away from the thermal insulation layer 12 is installed with a connection top piece 18. The connection top piece 18 and the connection base 17 clamp both sides of the low-carbon steel wire mesh 15 and are fixedly connected by bolts. One end of the connection top piece 18 away from the connection base 17 is installed with a broken bridge waterproof cap 19.

[0039] In the above embodiment, it should be noted that the connection base 17 and the connection top piece 18 are made of alloy materials, and the broken bridge waterproof cap 19 is made of polyvinyl chloride. The core function of the broken bridge waterproof cap 19 is to protect the building structure from water penetration by preventing water from entering the inside of the connection piece, reducing the corrosion and damage of the structure by water. At the same time, the broken bridge waterproof cap 19 can also cut off heat transfer to play a role in reducing the thermal bridge phenomenon and improving the thermal insulation performance of the building.

[0040] The construction method of an earthquake-resistant and heat-insulating integrated external shear wall of the present invention is as follows: First, the heat-insulating layer 12 is formed by co-extruding polystyrene resin with special additives at high temperature in a factory. The heat-insulating layer 12 is transported to the construction site and installed at the preset position. Subsequently, workers use an electric cutting knife or an electric grinding wheel to open longitudinal slots on both sides of the heat-insulating layer 12. After that, the heat-insulating layer 12 needs to undergo a special heat-insulation acceptance; after the heat-insulating layer 12 passes the special heat-insulation acceptance, workers fill the lower ends of the longitudinal slots on both sides of the heat-insulating layer 12 with wire mesh pedestals 21, and then stack and install wire mesh frames 20 on the upper ends of the wire mesh pedestals 21 in sequence until the longitudinal slots on both sides of the heat-insulating layer 12 are filled. During installation, it is necessary to make the grid joints 22 at the lower ends of each wire mesh frame 20 insert downward into the wire mesh frame 20 or the wire mesh pedestal 21 below and contact the top surface of the arched grid 23 inside it; then, workers bind the steel bar grid on one side of the heat-insulating layer 12 with steel bars 14. Subsequently, holes are opened on the other side of the heat-insulating layer 12 and connecting bases 17 are inserted. The low-carbon steel wire mesh 15 is placed on one side of the connecting base 17. Then, the connecting top pieces 18 are connected to the connecting bases 17 with bolts and clamp and fix the low-carbon steel wire mesh 15. Finally, broken-bridge waterproof caps 19 are installed at the ends of the connecting top pieces 18 in sequence; first, formwork for the structural wall is installed on three sides of the low-carbon steel wire mesh 15 away from the heat-insulating layer 12, and then formwork for the structural wall is installed on three sides of the steel bar grid away from the heat-insulating layer 12. Before concrete pouring, a 25-30 type vibrating rod is inserted between the heat-insulating layer 12 and the wall formwork, and then concrete is poured. At the same pouring point, it is advisable to adopt a push-type continuous pouring. When switching between multiple pouring points, the next layer of concrete should be poured before the previous layer of concrete begins to set. As the concrete level rises, the vibrating rod is gradually pulled out. When the concrete is locally blocked, it can be rammed with a steel bar. During concrete pouring, the liquid level difference between the concrete on both sides of the heat-insulating layer 12 should not be greater than 400 mm. After the concrete on both sides of the heat-insulating layer 12 solidifies to form the structural layer 11 and the structural layer 13, the formwork for the structural wall and the formwork for the structural wall are removed. After the formwork is removed, maintenance measures should be immediately taken for the structural layer 11 and the structural layer 13, and the maintenance time should not be less than 14 days.

[0041] The above is only a preferred embodiment of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present invention shall fall within the scope of protection required by the present invention.

After the concrete on both sides of the insulation layer (12) solidifies to form the structural layer (11) and the structural layer (13), the structural wall formwork and the structural wall formwork are removed. After the formwork is removed, maintenance measures should be taken immediately for the structural layer (11) and the structural layer (13), and the maintenance time should not be less than 14 days.
