Description

Technical Field

[0001] The invention relates to the technical field of buildings, and in particular to an assembled shock-absorbing wall panel and an installation method thereof. Background Art

[0002] The original infill wall structure is made of masonry or prefabricated panels (such as ALC panels, prefabricated concrete panels, fiberglass sound insulation panels, etc.), connected with mortar or cement, special adhesives, and built or spliced ​​piece by piece and layer by layer. When an earthquake occurs, these connected parts are the weakest places, and the infill walls will be damaged in these places, especially the stairwells, which are life passages for escape and should be kept unobstructed and should not be damaged before the main structure. When the original infill walls encounter an earthquake, the walls will crack and collapse, seriously affecting escape and rescue.

[0003] At the same time, the tensile and shear strength of the masonry structure is very low, and its seismic performance is also poor. Its use is subject to certain restrictions, and its construction efficiency is low. When wet operations are used, it has a certain impact on the surrounding environment. When the masonry is higher and longer, additional tie bars, structural columns, and ring beams are required, which increases the cost. When the masonry reaches the top surface, a certain process interval time is required, generally about 7 days, which affects the construction of the next process and is not conducive to the construction period.

[0004] The joints of prefabricated ALC wall panels are prone to cracking. When the panels are long, the temperature difference is large, which is easy to deform. Repairing after damage can easily cause secondary falling off. Prefabricated concrete panels are heavy in weight, inconvenient to transport and install, and require special machinery and multiple people to install. In addition, the panels are thin in wall, poor in thermal insulation, poor in load-bearing capacity, and weak in stability, so their use has been restricted. Summary of the invention

The invention provides an assembled shock-absorbing wall panel and an installation construction method, which reduces the installation difficulty, improves the construction convenience, shortens the construction period, improves the structural stability, reduces the collapse rate of the wall during an earthquake, ensures the smoothness of the escape passage, and reduces the maintenance cost.

[0006] In order to achieve the above-mentioned object, the present invention provides an assembled shock-absorbing wall panel, which has a first direction and a second direction intersecting each other, and includes a plurality of partition boards extending along the first direction and a fixing assembly, wherein the adjacent partition boards are sequentially connected along the second direction, and each of the partition boards is respectively connected with the fixing assembly;

At least a portion of the end of the partition board facing the first fixing member is inserted into the limiting groove, and the end of the partition board away from the first fixing member is connected to the second fixing member.

[0011] As a preferred solution, an insertion groove is provided on one end surface of the partition board facing the second fixing member, one end of the second fixing member is connected to the insertion groove, and the other end of the second fixing member is used to be connected to the concrete structure.

[0012] As a preferred solution, the insertion groove is filled with mortar, and the mortar surrounds and fixes the second fixing piece.

[0013] As a preferred embodiment, the plug-in groove includes an insertion section and a fixed section whose extension directions intersect each other, one end of the insertion section is opened on a side surface of the partition board to form an insertion port, the other end of the insertion section is connected to one end of the fixed section, the second fixing piece is inserted into and fixed to the fixed section through the insertion port, and the mortar layer fills the insertion section and the fixed section respectively.

[0014] As a preferred solution, the fixing components of adjacent partition boards are staggered along the second direction.

[0015] As a preferred solution, a mortar layer is provided at one end of the partition board in the second direction, and adjacent partition boards are connected via the mortar layer.

[0016] A method for installing and constructing an assembled shock-absorbing wall panel, wherein the wall panel assembly is installed between oppositely located concrete structures, wherein the oppositely arranged concrete structures are configured as a first concrete structure and a second concrete structure, and the method comprises the following steps:

[0017] prefabrication step, opening a fixing hole in the second concrete structure, inserting one end of the second fixing member into and fixing the fixing hole, and extending the other end toward the first concrete structure;

One end of the partition panel is inserted into the limiting groove, and the other end is connected to the concrete structure through the second fixing member, thereby being able to withstand large lateral forces and not prone to collapse. At the same time, one end of the partition panel is located in the limiting groove of the first fixing member, and the first fixing member provides stable support and limiting effects for the partition panel to prevent the partition panel from being displaced under the action of lateral forces. Since the connection method between the partition board and the fixed component has a high degree of integrity, the main structure of the wall panel assembly is usually not seriously damaged after an earthquake, which reduces the cracking of the partition board in the later stage. Usually, cracking only occurs at the joints of adjacent partition boards.

[0036] In the description of the present invention, it should be understood that the terms "connected", "connected", "fixed" and the like used in the present invention should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a welding connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figures 1 to 5 As shown, an assembled shock-absorbing wall panel according to a preferred embodiment of the present invention has a first direction X and a second direction Y intersecting each other, and includes a plurality of partition panels 10 and a fixing assembly 20 extending along the first direction X, wherein adjacent partition panels 10 are sequentially connected along the second direction Y, and each of the partition panels 10 is respectively connected with the fixing assembly 20;

[0038] The fixing component 20 includes an elastic component 21 and a first fixing member 24 and a second fixing member 26 for connecting to a concrete structure. The first fixing member 24 and the second fixing member 26 are arranged opposite to each other at two ends of the partition board 10 in the first direction X. The first fixing member 24 is provided with a limiting groove 25 extending along the second direction Y on the side facing the partition board 10. The elastic component 21 is located in the limiting groove 25. One end of the elastic component 21 is connected to the first fixing member 24, and the other end is connected to one end of the partition board 10. At least a portion of the end of the partition board 10 facing the first fixing member 24 is inserted into the limiting groove 25, and the end of the partition board 10 away from the first fixing member 24 is connected to the second fixing member 26.

[0039] The assembled shock-absorbing wall panel and the installation construction method thereof of the present invention, the wall panel assembly includes a plurality of partition panels 10 and a fixing assembly 20, the plurality of partition panels 10 are sequentially connected along the second direction Y, and the partition panels 10 are spliced ​​in a whole-board manner, thereby reducing the joints between a large number of bricks or blocks in traditional masonry. Each partition panel 10 is connected to the concrete structure through a fixing assembly 20 to form a wall system with strong integrity, thereby reducing cracks caused by local stress concentration. Due to the small number of joints and firm connection, the wall panel is not prone to cracks when subjected to temperature changes, shrinkage or slight vibrations. At the same time, it can withstand large lateral forces and is not prone to collapse during an earthquake. One end of the partition panel 10 is inserted into the limit groove 25, and the other end is connected to the concrete structure through a second fixing member 26, so it can withstand large lateral forces and is not prone to collapse. At the same time, one end of the partition board 10 is located in the limiting groove 25 of the first fixing member 24, and the first fixing member 24 provides stable support and limiting effect for the partition board 10, preventing the partition board 10 from being displaced under the action of lateral force. Since the connection method between the partition board 10 and the fixing assembly 20 has a high degree of integrity, the main structure of the wall panel assembly will not usually be seriously damaged after an earthquake, reducing the cracking of the partition board 10 in the later period. Usually, only cracking occurs at the joints of adjacent partition boards 10, and only simple plastering repairs are needed at the joints to restore the function of the wall, with low maintenance costs and fast repair speed. A partition board 10 is connected to a fixing assembly 20 to form an assembly unit. The assembly unit has few connecting parts, and only splicing and fixing are required on site. There are few joints between adjacent assembly units, the construction speed is fast, the construction method is simple, and the maintenance cost is low.

[0040] As one embodiment, the first fixing member 24 is a channel steel.

[0041] As one embodiment, the first fixing member 24 is fixed to the concrete structure by an expansion bolt 32 .

[0042] As one embodiment, the partition wall board 10 is an ALC board, that is, a lightweight partition wall board 10 .

[0043] Further, such as Figures 1 to 4 As shown, the elastic component 21 includes an elastic member 22 and a pad 23, one end of the elastic member 22 is connected to the first fixing member 24, and the other end is connected to the pad 23, and the pad 23 is connected to the partition board 10. The elastic member 22 is connected to the partition board 10 through the pad 23, and the pad 23 can disperse the pressure of the elastic member 22 on the partition board 10 to a larger area, effectively reducing the local pressure of the elastic member 22 on the partition board 10 and avoiding the partition board 10 from cracking. The pre-tightening force of the elastic member 22 can tightly combine the partition board 10 with the pad 23, improve the stability of the connection, and prevent loosening and falling off. Among them, the elastic member 22 can reduce the impact of earthquakes on the partition board 10 and improve the seismic resistance of the connection. The steel pad 23 can improve the rigid support, prevent the partition board 10 from excessive displacement during vibration, and improve the stability of the connection.

[0044] As one embodiment, the elastic member 22 and the backing plate 23 are welded to form an integrated structure, which simplifies the installation process and improves the installation efficiency.

[0045] As one embodiment, the elastic member 22 is a spring. The backing plate 23 is a steel backing plate 23 .

[0046] Further, such as Figure 1 to Figure 2 As shown, the elastic components 21 are provided in plurality, and adjacent elastic components 21 are arranged at intervals along the second direction Y, and the plurality of elastic components 21 connected to the same partition board 10 are located on the same side of the partition board 10. The plurality of elastic components 21 disperse the pressure on the partition board 10 to avoid local stress concentration, thereby improving the overall bearing capacity of the partition board 10, while providing more stable support, reducing the shaking and deformation of the partition board 10, and improving its overall stability. By adjusting the number, position and parameters of the elastic components 21, the support stiffness and elastic expansion characteristics of the partition board 10 can be adjusted more flexibly to meet different needs.

[0047] Further, such as Figure 1 As shown, the elastic component 21 and the second fixing member 26 extend respectively along the first direction X, and the positions of the elastic component 21 and the second fixing member 26 in the first direction X are set correspondingly, allowing adjacent partition boards 10 to move relatively along the first direction X (horizontal direction) at the joints during an earthquake, which can release the horizontal stress caused by the earthquake and avoid stress concentration leading to structural damage of the partition board 10 as a whole. The second fixing member 26 provides a certain restraining force on the partition board 10 to prevent the partition board 10 from excessive displacement, maintain the stability of the overall structure, and prevent the partition board 10 from falling off during an earthquake. The elastic component 21 coordinates the movement between adjacent partition boards 10, and the adjacent partition boards 10 can work together to resist the earthquake force.

[0048] As one embodiment, the second fixing member 26 is a steel bar.

[0049] Further, such as Figure 1 and Figure 5 As shown, the partition board 10 is provided with a plug-in slot 11 on one end surface facing the second fixing member 26, one end of the second fixing member 26 is connected to the plug-in slot 11, and the other end of the second fixing member 26 is used to connect to the concrete structure. The plug-in slot 11 makes the connection between the partition board 10 and the second fixing member 26 more convenient, without the need for complicated welding or bolt connection, simplifies the installation process, and improves construction efficiency. It reduces construction costs, improves construction efficiency, and reduces labor costs. The plug-in slot 11 is pre-set on the partition board 10, which is convenient for on-site installation, reduces the need for on-site processing, improves construction accuracy, and shortens on-site construction time.

[0050] Further, such as Figure 1 and Figure 5 As shown, the plug-in slot 11 is filled with mortar 12, and the mortar 12 surrounds and fixes the second fixing member 26. The mortar 12 forms a firm bond between the plug-in slot 11 and the second fixing member 26, improves the connection strength, and strengthens the connection between the partition board 10 and the concrete structure. The use of mortar 12 can simplify the construction process, eliminate the need for complex welding or bolt connections, and improve construction efficiency. The mortar 12 can adapt to plug-in slots 11 and second fixing members 26 of different shapes and sizes, and has strong adaptability.

[0051] As one embodiment, the mortar layer 16 is a mortar 12 of M2.5.

[0052] Further, such as Figure 1 and Figure 5As shown, the plug-in slot 11 includes an insertion section 13 and a fixing section 14 whose extension directions intersect, one end of the insertion section 13 is opened on one side of the partition board 10 to form an insertion opening 15, the other end of the insertion section 13 is connected with one end of the fixing section 14, the second fixing member 26 is inserted and fixed to the fixing section 14 through the insertion opening 15, and the mortar layer 16 fills the insertion section 13 and the fixing section 14 respectively. The second fixing member 26 enters the insertion section 13 through the insertion opening 15, and moves from the insertion section 13 to the fixing section 14, and is fixed by the mortar layer 16. The second fixing member 26 does not need to be pre-installed in the fixing section 14, but enters the insertion section 13 through the insertion opening 15, and then moves to the fixing section 14, which simplifies the installation steps, improves the installation efficiency, avoids the difficulty of installation in a narrow space, and reduces the difficulty of assembly. The setting of the insertion section 13 realizes the assembly positioning of the second fixing member 26, and the fixing section 14 provides an adjustment space for the connection position of the second fixing member 26 in the second direction Y. After the second fixing member 26 confirms the position in the fixing section 14, it is fixed by the mortar layer 16, which enhances the error resistance of the connection system, reduces the sensitivity to assembly accuracy, improves the reliability of assembly, reduces the difficulty of assembly, and makes the overall structure after assembly more stable.

[0053] As one embodiment, Figure 1 and Figure 5 As shown, the insertion section 13 extends along the third direction Z, and the fixing section 14 extends along the second direction Y, wherein the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0054] Further, such as Figure 1 As shown, the fixing components 20 of the adjacent partition boards 10 are arranged in a staggered manner along the second direction Y. That is, the adjacent partition boards 10 are configured as a first partition board 10 and a second partition board 10, with the fixing components 20 of the first partition board 10 at one end in the first direction X, and the fixing components 20 of the second partition board 10 at the other end in the first direction X. The staggered arrangement of the fixing components 20 can effectively disperse the seismic force, so that the adjacent partition boards 10 have a reverse movement trend during an earthquake. When subjected to a large horizontal force, the adjacent partition boards 10 are relatively displaced and cracked at the joints, thereby offsetting part of the seismic energy. By reducing the concentrated force on the side wall concrete mortar 12 of the partition board 10, the risk of its fracture is reduced, thereby improving the seismic performance of the overall structure, extending its service life, and improving the safety of personnel during an earthquake.

[0055] Further, such as Figure 1As shown, a mortar layer 16 is provided at one end of the partition board 10 in the second direction Y, and adjacent partition boards 10 are connected by the mortar layer 16. The mortar layer 16 serves as a bridge connecting adjacent partition boards 10, connecting the originally independent partition boards 10 into an integral structure, improving the overall rigidity and shear strength of the structure, and enhancing the seismic performance of the structure.

[0056] A method for installing and constructing an assembled shock-absorbing wall panel, such as Figures 1 to 5 As shown, the wall panel assembly is installed between oppositely located concrete structures, and the oppositely arranged concrete structures are configured as a first concrete structure 30 and a second concrete structure 31, including the following steps:

[0057] In the prefabrication step, a fixing hole is opened in the second concrete structure 31, one end of the second fixing member 26 is inserted into and fixed in the fixing hole, and the other end is extended toward the first concrete structure 30, so as to realize the pre-embedded fixation of the second fixing member 26 on the second concrete structure 31, and prepare for the connection between the second fixing member 26 and the partition board 10.

[0058] In the pre-assembly step, the size of the partition board 10 in the first direction X is cut. After one end of the partition board 10 in the first direction X is connected to the elastic component 21, at least a portion of it can be inserted into the limiting groove 25, and the other end is connected to the concrete structure through mortar 12. The partition board 10 has a first end face and a second end face in the first direction X, and the second end face is provided with a plug-in groove 11, which prepares for the subsequent connection of the second fixing member 26 with the partition board 10.

[0059] The first fixing step is to fix the first fixing member 24 to the first concrete structure 30 to fix the first fixing member 24. The welding position of the elastic component 21 in the second direction Y is determined according to the position of the partition board 10 to ensure that the elastic component 21 can act on the partition board 10. The elastic component 21 is welded in the limiting groove 25 of the first fixing member 24 to improve the integrity of the connection structure between the elastic component 21 and the first fixing member 24. The elastic component 21 is arranged corresponding to the position of the second fixing member 26 in the second direction Y;

[0060] In the assembly step, the first end face of the partition board 10 is inserted into the limiting groove 25 and the elastic component 21 is squeezed. The limiting groove 25 is used to limit and support the position of the partition board 10. The elastic component 21 is in an extruded state, preparing for the assembly connection between the second fixing member 26 and the partition board 10, thereby realizing the assembly and connection between the first end face of the partition board 10 and the fixing component 20.

[0061] In the second fixing step, the second fixing member 26 is inserted into the plug-in slot 11, and the mortar 12 is filled in the plug-in slot 11 to fix the second fixing member 26 to the partition board 10. The plug-in slot 11 makes the connection between the partition board 10 and the second fixing member 26 more convenient, without complicated welding or bolt connection, simplifying the installation process and improving construction efficiency. The construction cost is reduced, while the construction efficiency is improved and the labor cost is reduced. The plug-in slot 11 is pre-set on the partition board 10, which is convenient for on-site installation, reduces the need for on-site processing, improves construction accuracy, and shortens the on-site construction time. Mortar 12 is applied to the second end face, and the partition board 10 is connected and fixed to the second concrete structure 31 through the mortar 12 under the thrust of the elastic component 21. Under the thrust of the elastic component 21, the partition board 10 can be tightly connected to the second concrete structure 31 through the mortar 12, improving the reliability and stability of the connection, and completing the assembly connection between the second end face of the partition board 10 and the fixing component 20.

[0062] The partition board 10 connection step is to apply mortar 12 on the end surface of the partition board 10 in the second direction Y to connect and fix it with the adjacent partition board 10, and repeat the above steps for assembling the adjacent partition boards 10 and the fixing components 20.

[0063] As one embodiment, during the installation of the next partition board 10, the first fixing member 24 is connected to the second concrete structure 31, and the second fixing member 26 is connected to the first concrete structure 30. On this basis, during the installation of the next partition board 10, the first fixing member 24 is connected to the first concrete structure 30, and the second fixing member 26 is connected to the second concrete structure 31. The first fixing member 24 and the second fixing member 26 are respectively arranged at the connection positions with the concrete structures in an alternating manner.

[0064] As one of the embodiments, in the prefabrication step, an impact drill is used to open a fixing hole on the second concrete structure 31, and the second fixing member 26, i.e., a steel bar, is inserted into the fixing hole and filled with anchor glue to fix the second fixing member 26 to the concrete structure. The second fixing member 26 is pre-buried and installed in advance, and a pull-out test is required before installing the shock-absorbing wall panel.

[0065] As one embodiment, in the first fixing step, the first fixing member 24 is connected to the first concrete structure 30 via the expansion bolt 32 .

[0066] As one embodiment, the floor height of the stairwell is generally 3000mm-4200mm. This embodiment is explained using the case where the floor height of the stairwell is 4200mm.

Position the partition board 10 to be installed on the surface of the first fixing member 24, then position the elastic component 21 in the limiting groove 25 of the first positioning member, and weld the two elastic components 21. One end of the elastic member 22 of the elastic component 21 has been welded to the steel pad 23 in advance. The spacing between the elastic components 21 in the same partition board 10 is 300mm, and the second concrete structure 31 at the other end is passed through Two second fixing members 26, i.e. short steel bars, are implanted through positioning. The exposed length of the second fixing members 26 is 100mm. The spacing between the two second fixing members 26 in the second direction Y is 300mm, and they are on the same horizontal line as the positioning point of the elastic component 21. After the above work is completed, the partition board 10 is installed from bottom to top. When installing the first partition board 10, the end without the L groove is inserted into the limiting groove 25, and the partition board 10 is pulled into the limiting groove 25 with force to compress the elastic component 21 by 3-8mm. At this time, the short steel bar at the other end is inserted into the partition board 10 through the L-shaped groove, and the end face facing the second concrete structure 31 has been fully smeared with M5 mortar 12 in advance. Under the thrust of the elastic component 21, the M5 mortar 12 will tightly connect the partition board 10 and the second concrete structure 31. After installing the first partition board 10, the top surface of the first partition board 10 is fully smeared with mortar 12, and the remaining partition boards 10 are installed in sequence according to this step.

[0069] In summary, the embodiment of the present invention provides an assembled shock-absorbing wall panel and an installation construction method. The wall panel assembly includes a plurality of partition panels 10 and a fixing assembly 20. The plurality of partition panels 10 are connected in sequence along the second direction Y. The partition panels 10 are spliced ​​in a whole-board manner, which reduces the joints between a large number of bricks or blocks in traditional masonry. Each partition panel 10 is connected to the concrete structure through a fixing assembly 20 to form a wall system with strong integrity, thereby reducing cracks caused by local stress concentration. Due to the small number of joints and firm connections, the wall panel is not prone to cracks when subjected to temperature changes, shrinkage or slight vibrations. At the same time, it can withstand large lateral forces and is not prone to collapse during an earthquake. One end of the partition panel 10 is inserted into the limit groove 25, and the other end is connected to the concrete structure through a second fixing member 26, which can withstand large lateral forces and is not prone to collapse. At the same time, one end of the partition board 10 is located in the limiting groove 25 of the first fixing member 24, and the first fixing member 24 provides stable support and limiting effect for the partition board 10, preventing the partition board 10 from being displaced under the action of lateral force. Since the connection method between the partition board 10 and the fixing assembly 20 has a high degree of integrity, the main structure of the wall panel assembly will not usually be seriously damaged after an earthquake, reducing the cracking of the partition board 10 in the later period. Usually, only cracking occurs at the joints of adjacent partition boards 10, and only simple plastering repairs are needed at the joints to restore the function of the wall, with low maintenance costs and fast repair speed. A partition board 10 is connected to a fixing assembly 20 to form an assembly unit. The assembly unit has few connecting parts, and only splicing and fixing are required on site. There are few joints between adjacent assembly units, the construction speed is fast, the construction method is simple, and the maintenance cost is low.

[0070] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
