Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a seismic-resistant wall structure for buildings and its construction method. Background Technology

[0002] Frame structures are widely used in high-rise residential buildings and multi-story industrial plants due to their good load-bearing capacity. Frame structures are mainly composed of beams and columns connected by steel bars to form a load-bearing structure that can withstand all the loads that occur during the use of the building. In other words, the beams and columns form a frame that jointly resists the horizontal and vertical loads that occur during use. The walls of frame structure buildings are not load-bearing and only serve the functions of enclosure and partition.

[0003] Currently, when constructing frame structure buildings, the foundation, building frame structure, and floor slabs are usually built first, and then the walls are constructed. Since the walls of frame structure buildings are built on the frame structure by masonry in the later stage, the connection between the walls and the frame columns is limited, and the lateral stiffness of the frame structure is small. When an earthquake occurs, the angle between the beams and columns of the frame structure is likely to change, which will put pressure on the walls, making them prone to deformation and cracks. In severe cases, it may even lead to the collapse of the walls. Summary of the Invention

[0004] To improve the seismic performance of walls, this application provides a seismic-resistant wall structure for buildings and its construction method.

[0005] Firstly, this application provides a seismic-resistant wall structure for building construction, which adopts the following technical solution:

[0006] An earthquake-resistant wall structure for a building includes a structural frame fixedly mounted on a column, and inner wall panels and outer wall panels respectively installed on both sides of the structural frame. A connecting skeleton is provided within the structural frame, and multiple stress-resistant tie rods are hinged to the side walls of the connecting skeleton. Each stress-resistant tie rod is distributed circumferentially along the connecting skeleton, and the end of each stress-resistant tie rod furthest from the connecting skeleton is hinged to the structural frame. A fixing mechanism for fixing the inner wall panels and outer wall panels is provided on the connecting skeleton. Placement slots for placing the inner wall panels or outer wall panels are provided on both sides of the structural frame. Elastic structural members are fixedly mounted on the side walls of the placement slots, and these elastic structural members abut against the edges of the inner wall panels or outer wall panels.

[0007] Optionally, the fixing mechanism includes a mounting bracket and a limiting component. The mounting bracket is fixedly installed on the back of both the inner wall panel and the outer wall panel. The connecting frame has mounting slots on both sides that are adapted to the mounting bracket. The limiting component is installed in both mounting slots to prevent the mounting bracket from detaching from the mounting slot.

[0008] Optionally, the limiting component includes an insert block and an elastic element. The side wall of the mounting groove is provided with a receiving groove. The insert block is slidably disposed in the receiving groove. The elastic element is used to drive the insert block to slide away from the bottom wall of the receiving groove. The mounting frame is provided with a insertion groove for inserting the insert block. The end of the insert block away from the bottom wall of the receiving groove is provided with a guide slope. The guide slope is used to abut against the mounting frame and guide the insert block to slide closer to the bottom wall of the receiving groove.

[0009] Optionally, a sealing groove is provided on the outer side wall of the structural frame along the circumference of the structural skeleton, an expansion sealing bag is provided in the sealing groove, the expansion sealing bag is connected to a feed pipe, an injection port communicating with the sealing groove is opened on the side wall of the structural frame, the feed pipe is located in the injection port, and the expansion sealing bag is used to fill foaming agent.

[0010] Optionally, both placement slots have a connecting slot on their sidewalls that communicates with the sealing slot. A sealing strip is provided in the connecting slot. The sealing strip has a cavity inside and is used to press against the end of the inner wall panel or the outer wall panel.

[0011] Optionally, the space between the inner wall panel and the outer wall panel is filled with thermal insulation foam material, and the inner wall panel has a filling opening.

[0012] Optionally, structural steel plates are embedded inside both the inner wall panel and the outer wall panel. The end face of the structural steel plate on the inner wall panel away from the outer wall panel is honeycomb-shaped, and the end face of the structural steel plate on the outer wall panel away from the inner wall panel is honeycomb-shaped.

[0013] Optionally, the elastic structural component includes an elastic frame strip, which is made of elastic steel and has a U-shaped cross-section.

[0014] Optionally, the elastic structural component includes a frame plate and a plurality of shock-absorbing sleeves fixedly mounted on the frame plate. The shock-absorbing sleeves are made of elastic steel. The frame plate is fixedly connected to the structural frame. The shock-absorbing sleeves are used to abut against the edge of the inner wall panel or the outer wall panel.

[0015] Secondly, this application provides a construction method for a seismic-resistant wall structure of a building, employing the following technical solution:

[0016] A construction method for a seismic-resistant wall structure in a building includes the following steps:

[0017] S1. Fix the structural frame at the construction location of the wall. The two sides of the structural frame abut against the columns on both sides, the top of the structural frame abuts against the beam, and the bottom of the structural frame abuts against the floor slab. Fix the two sides of the structural frame to the columns with expansion bolts.

[0018] S2. Install the inner wall panel and the outer wall panel on both sides of the structural frame respectively. The inner wall panel is located in the placement groove on one side of the structural frame, and the outer wall panel is located in the placement groove on the other side of the structural frame. Make the elastic structural member abut against the edge of the inner wall panel or the outer wall panel, and then fix the inner wall panel and the outer wall panel to the connecting frame.

[0019] S3. Fill the expansion sealing bag with foaming agent through the injection port. During the filling process, the expansion sealing bag expands and seals the gaps between the structural frame and the columns, beams and floor slabs. As the expansion sealing bag expands, it squeezes the sealing strips in the two placement slots, thereby sealing the gaps between the structural frame and the inner wall panel and the outer wall panel.

[0020] S4. Fill the space between the inner wall panel and the outer wall panel with thermal insulation foam material through the filling opening of the inner wall panel.

[0021] In summary, this application has the following beneficial technical effects:

[0022] 1. This application increases the structural stability of the frame by setting a connecting skeleton within the structural frame and connecting the connecting skeleton to the structural frame through multiple stress-resistant tie rods. When an earthquake occurs, causing a change in the angle between the beams and columns of the frame structure, the structural frame will be compressed first. The structural strength of the frame itself and the stress-resistant tie rods will weaken the stress. When the stress on the structural frame is too great and exceeds its own stress deformation limit, the structural frame will deform. At this time, the edges of the inner or outer wall panels will be compressed by the elastic structural members. The elastic structural members will undergo elastic deformation, thereby weakening the stress. This makes the inner and outer wall panels less prone to deformation and cracking, or collapse, greatly improving the seismic performance of the wall. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] This application discloses an earthquake-resistant structure for building walls. (Refer to...) Figure 1 The structure includes a structural frame 1 fixed at the construction location of the wall, and an inner wall panel 2 and an outer wall panel 3 respectively installed on both sides of the structural frame 1. The two sides of the structural frame 1 abut against the columns on both sides, the top of the structural frame 1 abuts against the beam, and the bottom of the structural frame 1 abuts against the floor slab. The two sides of the structural frame 1 are fixed to the columns by expansion bolts.

[0032] Reference Figure 1 The structural frame 1 is provided with a connecting skeleton 4. Multiple stress-resistant tie rods 41 are hinged to the side walls of the connecting skeleton 4. In this embodiment, there are four stress-resistant tie rods 41, which are distributed circumferentially along the connecting skeleton 4. The end of the stress-resistant tie rod 41 away from the connecting skeleton 4 is hinged to the structural frame 1, and the connection end of each stress-resistant tie rod 41 to the structural frame 1 is located at the corner of the structural frame 1. The stability of the structural frame 1 is increased by multiple stress-resistant tie rods 41. When an earthquake occurs, causing the angle between the beams and columns of the frame structure to change, the structural frame 1 will be compressed first. The stress is weakened by the structural strength of the structural frame 1 itself and by each stress-resistant tie rod 41.

[0033] Reference Figure 2 , 3 Both the inner wall panel 2 and the outer wall panel 3 are embedded with structural steel plates 5. The end face of the structural steel plate 5 in the inner wall panel 2 away from the back of the inner wall panel 2 is honeycomb-shaped, and the end face of the structural steel plate 5 in the outer wall panel 3 away from the back of the outer wall panel 3 is also honeycomb-shaped. The structural steel plates 5 increase the structural strength of the inner wall panel 2 and the outer wall panel 3, and the honeycomb-shaped end face of the structural steel plate 5 increases the sound insulation effect of the inner wall panel 2 and the outer wall panel 3 to a certain extent. At the same time, the honeycomb-shaped structural steel plate 5 can also increase the thermal insulation performance of the inner wall panel 2 and the outer wall panel 3 themselves.

[0034] Reference Figure 2 The inner wall panel 2 has a filling opening 21 through the inner wall panel 2 on its end face. The space between the inner wall panel 2 and the outer wall panel 3 is filled with thermal insulation foam material 6, which is polyurethane foam insulation material. After the inner wall panel 2 and the outer wall panel 3 are installed, thermal insulation foam material 6 is filled between the inner wall panel 2 and the outer wall panel 3 through the filling opening 21 to increase the thermal insulation performance of the wall.

[0035] Reference Figure 2 , 4 The connecting frame 4 is provided with a fixing mechanism for fixing the inner wall panel 2 and the outer wall panel 3. The fixing mechanism includes a mounting bracket 7 and a limiting component. The mounting bracket 7 is fixedly installed on the back of both the inner wall panel 2 and the outer wall panel 3. The mounting bracket 7 on the inner wall panel 2 is fixedly connected to the structural steel plate 5 inside the inner wall panel 2. The mounting bracket 7 on the outer wall panel 3 is fixedly connected to the structural steel plate 5 inside the outer wall panel 3. The connecting frame 4 has mounting grooves 42 on both sides that are adapted to the mounting bracket 7.

[0036] Reference Figure 4 Both mounting slots 42 are provided with limiting components, which include insert blocks 43 and elastic elements 44. The side walls of the mounting slots 42 are provided with multiple receiving slots, and each receiving slot is slidably provided with an insert block 43. The side walls of the insert blocks 43 are fixedly provided with limiting blocks. The side walls of the receiving slots are provided with limiting slots along the sliding direction of the insert blocks 43. The limiting blocks are slidably provided in the limiting slots. The elastic element 44 includes a compression spring. Each receiving slot is provided with a compression spring. One end of the compression spring abuts against the bottom of the receiving slot, and the other end of the compression spring abuts against the insert block 43.

[0037] Reference Figure 4 The mounting bracket 7 has multiple insertion slots 71 for inserting the plug 43. Each insertion slot 71 corresponds to a plug 43. The end of the plug 43 away from the bottom wall of the receiving groove is provided with a guide slope. The guide slope gradually moves away from the compression spring along the direction close to the bottom wall of the mounting groove 42. When installing the inner wall panel 2 or the outer wall panel 3, the mounting bracket 7 on the inner wall panel 2 or the outer wall panel 3 is inserted into the mounting groove 42 on the connecting frame 4. As the mounting bracket 7 is inserted, the mounting bracket 7 abuts against the guide slope on each plug 43 and pushes the plug 43 closer to the receiving groove through the guide slope. The compression spring is compressed, so that the mounting bracket 7 can be smoothly inserted into the mounting groove 42 of the connecting frame 4. When the plug 43 is aligned with the corresponding insertion slot 71 on the mounting bracket 7, the plug 43 is inserted into the insertion slot 71 on the mounting bracket 7, which can prevent the mounting bracket 7 from detaching from the mounting groove 42.

[0038] Reference Figure 2 , 5A sealing groove 11 is provided on the outer side wall of the structural frame 1 along the circumference of the structural skeleton. An expansion sealing bag 12 is provided in the sealing groove 11. The expansion sealing bag 12 is connected to a feed pipe 121. An injection port 13 communicating with the sealing groove 11 is opened on the side wall of the structural frame 1. The feed pipe 121 passes through and is fixed in the injection port 13. Foaming agent is filled into the expansion sealing bag 12 through the injection port 13. During the filling process of the foaming agent, the expansion sealing bag 12 expands and seals the gaps between the structural frame 1 and the columns, beams and floor slabs.

[0039] Reference Figure 5 Both sides of the structural frame 1 are provided with placement grooves 14 for placing inner wall panels 2 or outer wall panels 3. The side walls of the two placement grooves 14 that are close to each other are provided with connecting grooves 15 along the circumference of the structural frame 1. The side walls of the connecting grooves 15 are provided with multiple connecting ports 151 that communicate with the sealing grooves 11. A sealing strip 16 is provided in the connecting groove 15, and the sealing strip 16 has a cavity inside. As the expanding sealing bag 12 expands, the expanding sealing bag 12 enters the connecting groove 15 through the connecting port 151 and squeezes the sealing strip 16 in the two placement grooves 14, thereby sealing the gap between the structural frame 1 and the inner wall panel 2 and the outer wall panel 3.

[0040] Reference Figure 5 Both sides of the structural frame 1 are provided with baffle frames 17. After the inner wall panel 2 or the outer wall panel 3 is installed, baffle frames 17 are installed on both sides of the structural frame 1 and welded to the structural frame 1 to cover the placement groove 14. After the baffle frames 17 are installed, they abut against the ends of the inner wall panel 2 or the outer wall panel 3, thereby increasing the stability of the inner wall panel 2 or the outer wall panel 3 in the placement groove 14.

[0041] Reference Figure 5 When the inner wall panel 2 or the outer wall panel 3 is placed into the placement groove 14, the edges of the inner wall panel 2 or the outer wall panel 3 are fitted with the side wall of the placement groove 14 with a gap. An elastic structural member 8 is provided at the gap between the side wall of the placement groove 14 and the edge of the inner wall panel 2 or the outer wall panel 3. When the structural frame 1 is subjected to excessive stress and exceeds its own stress deformation limit, the structural frame 1 deforms. At this time, the edge of the inner wall panel 2 or the outer wall panel 3 is squeezed by the elastic structural member 8, and the elastic structural member 8 undergoes elastic deformation, thereby weakening the stress. This makes it less likely for the inner wall panel 2 and the outer wall panel 3 to deform and crack, or to collapse, greatly improving the seismic performance of the wall.

[0042] Example 1

[0043] Reference Figure 5The elastic structural component 8 includes an elastic frame strip 81, which is adapted to the placement groove 14. The outer wall of the elastic frame strip 81 is fixedly connected to the side wall of the placement groove 14. The elastic frame strip 81 is made of elastic steel and has a U-shaped cross section. A notch is provided at the corner of the inner side of the elastic frame plate 82. When the inner wall panel 2 or the outer wall panel 3 is installed in the placement groove 14, the edge of the inner wall panel 2 or the outer wall panel 3 abuts against the inner side wall of the elastic frame strip 81 and squeezes the elastic frame strip 81.

[0044] Example 2

[0045] Reference Figure 6 The elastic structural component 8 includes a frame plate 82 and a plurality of shock-absorbing sleeves 83 fixedly mounted on the frame plate 82. The frame plate 82 is adapted to the placement groove 14. The outer side wall of the frame plate 82 is fixedly connected to the side wall of the placement groove 14. The shock-absorbing sleeves 83 are fixedly mounted on the inner side wall of the frame plate 82, and the plurality of shock-absorbing sleeves 83 are distributed along the circumference of the frame plate 82. The shock-absorbing sleeves 83 are made of elastic steel. When the inner wall panel 2 or the outer wall panel 3 is installed in the placement groove 14, the edge of the inner wall panel 2 or the outer wall panel 3 abuts against each shock-absorbing sleeve 83.

[0046] The implementation principle of the seismic-resistant wall structure of this application is as follows: This application increases the structural stability of the structural frame 1 by setting a connecting skeleton 4 inside the structural frame 1 and connecting the connecting skeleton 4 to the structural frame 1 through multiple stress-resistant tie rods 41. When an earthquake occurs, causing the angle between the beams and columns of the frame structure to change, the structural frame 1 will be compressed first. The stress is weakened by the structural strength of the structural frame 1 itself and by each stress-resistant tie rod 41. When the stress on the structural frame 1 is too large and exceeds its own stress deformation limit, the structural frame 1 deforms. At this time, the edge of the inner wall panel 2 or the outer wall panel 3 is compressed by the elastic structural member 8. The elastic structural member 8 undergoes elastic deformation, thereby weakening the stress, making it less likely for the inner wall panel 2 and the outer wall panel 3 to deform and crack or collapse, thus greatly improving the seismic performance of the wall.

[0047] This application also discloses a construction method for a seismic-resistant wall structure of a building, including the following steps:

[0048] S1. Fix the structural frame 1 at the construction position of the wall. The two sides of the structural frame 1 abut against the columns on both sides respectively. The top of the structural frame 1 abuts against the beam and the bottom of the structural frame 1 abuts against the floor slab. Fix the two sides of the structural frame 1 to the columns respectively with expansion bolts.

[0049] S2. Install the inner wall panel 2 and the outer wall panel 3 on both sides of the structural frame 1 respectively. The inner wall panel 2 is located in the placement groove 14 on one side of the structural frame 1, and the outer wall panel 3 is located in the placement groove 14 on the other side of the structural frame 1. Make the elastic structural member 8 abut against the edge of the inner wall panel 2 or the outer wall panel 3, and then fix the inner wall panel 2 and the outer wall panel 3 to the connecting frame 4.

[0050] S3. Foaming agent is filled into the expansion sealing bag 12 through the injection port 13. During the filling process, the expansion sealing bag 12 expands and seals the gaps between the structural frame 1 and the columns, beams and floor slabs. As the expansion sealing bag 12 expands, it squeezes the sealing strips 16 in the two placement grooves 14, thereby sealing the gaps between the structural frame 1 and the inner wall panel 2 and the outer wall panel 3.

[0051] S4. Insulating foam material 6 is filled between the inner wall panel 2 and the outer wall panel 3 through the filling port 21 of the inner wall panel 2.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
