Description

Technical Field

[0001] The invention relates to the technical field of shear walls, and in particular to an assembled concrete shear wall structure. Background Art

[0002] Shear wall is a cavity in a house or structure that mainly bears horizontal and vertical loads caused by wind loads or earthquakes to prevent structural shear damage. Prefabricated concrete shear wall structure is used in prefabricated building construction to improve construction efficiency.

[0003] Concrete shear wall structures are generally connected to each other through steel bars, and then connected through sleeve grouting, constrained grout anchors and sleeve extrusion. However, compared with cast-in-place shear wall structures, these connection methods have a large number of vertical joints and frame connection points. The connection of steel bars at the joints is the key to ensuring the integrity, seismic resistance and bearing capacity of the shear wall structure, which reduces the seismic resistance and bearing capacity of the shear wall.

[0004] There is a shear wall structure that pre-buries connectors between adjacent shear walls, and the corresponding connectors between the adjacent shear walls are contacted and welded to each other. Not only is the structure simple, but the connectors are plugged into each other, which reduces vertical joints and frame connection points and improves shear resistance and earthquake resistance. However, this connection method relies on welding for reinforcement, and welding is prone to defects such as pores or incomplete welding, which can easily cause problems with connection stability during the assembly of the shear wall, thereby affecting the safety performance of the house.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 3 As shown, the present invention provides an assembled concrete shear wall structure, including a plurality of first connecting members 1 and a plurality of second connecting members 2 respectively embedded in the assembly surfaces of two adjacent shear walls, and a third connecting member 3 is commonly arranged on the first connecting members 1 and the second connecting members 2.

[0036] Among them, the third connecting member 3 is used to clamp and connect the first connecting member 1 and the second connecting member 2 in a direction perpendicular to the outer wall of the largest area of ​​the shear wall after the first connecting member 1 and the second connecting member 2 are matched and inserted into each other, and fix the connection by filling concrete.

[0037] When the present invention is used, the first connector 1 is embedded in the assembly surface of one shear wall, the second connector 2 is embedded in the assembly surface of the adjacent shear wall, and multiple first connectors 1 and multiple second connectors 2 are arranged at equal intervals along the assembly surface of the shear wall.

[0038] During assembly, the first connecting member 1 and the corresponding second connecting member 2 are plugged into each other and then the connection state of the first connecting member 1 and the second connecting member 2 is locked in a direction perpendicular to the outer wall with the largest area of ​​the shear wall by the third connecting member, and the connection between the first connecting member 1 and the second connecting member 2 is locked by filling concrete to the third connecting member 3, thereby completing the assembly connection of two adjacent shear walls.

[0039] The present invention fixes the first connecting member 1 and the second connecting member 2 by the third connecting member 3, thereby completing the assembly connection between two adjacent shear walls, ensuring the shear resistance and earthquake resistance of the shear walls, reducing the dependence on external equipment and work processes, improving assembly efficiency, and avoiding the problem of air holes caused by fixing the connection by welding, which affects the stability of the connection between adjacent shear walls and thus affects the safety of the house.

[0040] In this embodiment, the shear wall assembly surfaces are surfaces facing each other when adjacent shear walls are assembled.

[0041] The first connecting member 1 includes a first embedded plate 101, a connecting plate 102 and a plurality of first annular plates 103, and the connecting plate 102 is vertically connected to the first embedded plate 101 along the length direction of the first embedded plate 101, and the plurality of first annular plates 103 are arranged at equal intervals along the length direction of the first embedded plate 101 on a side of the first embedded plate 101 away from the connecting plate 102.

[0042] The second connecting member 2 includes a second embedded plate 201, a connecting sleeve 202 and a plurality of second annular plates 203, and the connecting sleeve 202 is vertically arranged on the second embedded plate 201 and is used for slidingly connecting with the connecting plate 102, and the plurality of second annular plates 203 are arranged at equal intervals along the length direction of the second embedded plate 201 on the side of the second embedded plate 201 away from the connecting sleeve 202.

[0043] Among them, the first embedded plate 101 and the second embedded plate 201 are both embedded in the shear wall assembly surface close to the surface, the first annular plate 103 and the second annular plate 203 are both embedded in the shear wall, the connecting plate 102 and the connecting sleeve 202 are both located outside the shear wall and perpendicular to the shear wall assembly surface, and the third connecting member 3 is arranged on the connecting sleeve 202.

[0044] When the first connecting member 1 and the second connecting member 2 are in use, the first embedded plate 101 and the second embedded plate 201 are both embedded in the assembly surface of the corresponding shear wall, and the first annular plate 103 and the second annular plate 203 are both embedded in the assembly surface of the corresponding shear wall, and the embedded depth is deeper and they are respectively connected to the first embedded plate 101 and the second embedded plate 201 to ensure the stability of the first connecting member 1 and the second connecting member 2 on the shear wall.

[0045] The connecting plate 102 and the connecting sleeve 202 are slidably plugged in and fixedly connected by the third connecting member 3 to limit the disconnection between the connecting plate 102 and the connecting sleeve 202, thereby ensuring the stability of the connection between the two shear walls, and the inner wall of the connecting sleeve 202 interferes with the connecting plate 102, thereby improving the shear resistance of the connection.

[0046] The first annular plate 103 and the second annular plate 203 are both annular, which improves the tensile strength of the first connecting member 1 and the second connecting member 2 in the shear wall, thereby improving the stability of the connection between the two shear walls.

[0047] In this embodiment, the first embedded plate 101, the connecting plate 102, the first annular plate 103, the second embedded plate 201, the connecting sleeve 202 and the second annular plate are all made of steel.

[0048] The first annular plate 103 and the second annular plate 203 have the same structure. The first annular plate 103 includes a C-shaped plate 104 vertically connected to one side of the first embedded plate 101. Both sides of the C-shaped plate 104 are provided with extended plates 105 in a direction perpendicular to the outer wall of the shear wall with the largest area, and the extended plates 105 are parallel to the first embedded plate 101.

[0049] The opening of the U-shaped plate 104 is connected to the first embedded plate 101 to form a ring, thereby improving the tensile strength of the first connecting member 1 and the second connecting member 2.

[0050] Extension plates 105 are provided on both sides of the U-shaped plate 104, respectively, which enlarge the contact area between the first annular plate 103 and the second annular plate 203 inside the shear wall and the shear wall, further improving the tensile performance of the first connecting member 1 and the second connecting member 2, thereby improving the stability of the connection between the two shear walls.

[0051] A side plate 106 is fixedly connected to the plurality of C-shaped plates 104 at one side facing away from the first embedded plate 101 , and the side plate 106 and the plurality of C-shaped plates 104 are integrally formed.

[0052] By simultaneously connecting a plurality of C-shaped plates 104 through the side plates, the plurality of C-shaped plates 104 form a whole, thereby improving the stability of the first annular plate 103 and the second annular plate 203 in the shear wall and further increasing the contact area with the shear wall, thereby improving the tensile resistance of the first connecting member 1 and the second connecting member 2.

[0053] The third connecting member 3 includes a first through groove 301 arranged on one side of the connecting sleeve 202 along a direction perpendicular to the outer wall of the maximum area of ​​the shear wall and a clamping groove 302 arranged on the side wall of the connecting sleeve 202 relative to the first through groove 301. The inner side wall of the first through groove 301 is upwardly provided with a grouting groove 303 connected to the outside of the connecting sleeve 202 in a direction parallel to the shear wall assembly surface. A limit plate 304 is slidably connected in the first through groove 301 and moves along a direction perpendicular to the outer wall of the maximum area of ​​the shear wall. A second through groove 305 for the limit plate 304 to pass through is provided on the connecting plate 102.

[0054] When the connecting plate 102 is slidably inserted into the connecting sleeve 202 , the limiting plate 304 is slidably inserted into the slot 302 through the second through slot 302 , and the length of the limiting plate 304 is smaller than the distance between the bottom of the slot 302 and the grouting groove 303 .

[0055] When the third connecting member 3 is in use, after the connecting plate 102 is slidably inserted into the connecting sleeve 202 , the limiting plate 304 is pushed to slide along the first through slot 301 through the second through slot 305 into the locking slot 302 , thereby limiting the connecting plate 102 from being separated from the connecting sleeve 202 .

[0056] Then, concrete is filled from the grouting groove 303 into the first through groove 301 and the first through groove 301 is closed by the plate body, thereby completely fixing the position of the connecting plate 102 in the connecting sleeve 202 and ensuring the stability of the assembly connection of the two shear walls.

[0057] The grouting groove 303 extends upward to communicate with the outside of the connecting sleeve 202, so that the concrete can fall freely and fill the first through groove 301 during filling, thereby improving the convenience of use.

[0058] The limiting plate 304 includes a straight plate portion 306 and a wedge-shaped plate portion 307 , and the wedge-shaped plate portion 307 is disposed at one end of the straight plate portion 306 close to the slot 302 and is used to be locked into the slot 302 .

[0059] The second through groove 305 is a wedge-shaped groove that matches the surface shape of the wedge-shaped plate portion 307 and allows the wedge-shaped plate portion 307 to pass through.

[0060] By moving the wedge plate portion 307 to pass through the second through slot 305, the wedge plate portion 307 can be ensured to be in a state of abutment with the inner wall of the second through slot 305, thereby avoiding the problem of a gap between the limit plate 304 and the second through slot 305 affecting the connection stability when the connecting plate 102 passes through the limit position of the limit plate 304.

[0061] The straight plate portion 306 and the wedge-shaped plate portion 307 are slidably connected to the inner wall of the first through groove 301 at the same time.

[0062] An extension plate 308 is vertically arranged on one end of the straight plate portion 306 away from the slot 302 and is slidably connected to the side wall of the first through slot 301 opposite to the grouting slot 303. A closing plate 309 is arranged at the end of the extension plate 308 and is parallel to the outer wall with the largest area of ​​the shear wall.

[0063] The closing plate 309 is used to close the first through groove 301 when the limiting plate 304 is slidably inserted into the slot 302 , and the length of the extending plate 308 is greater than the size of the grouting groove 303 .

[0064] That is, the closing plate 309 is connected by the extension plate 308, so that the closing plate 309 closes the first through groove 301 after the connection plate 102 is limited by the limiting plate 304, so that when filling concrete, there is no need to close the first through groove 301 by an external plate body, thereby improving the convenience of use.

[0065] Furthermore, the concrete in the grouting groove 303 and the concrete in the first through groove 301 are connected as one, which further limits the limit plate 304 from being separated from the second through groove 305, thereby ensuring the stability of the connection.

[0066] The extension plate 308 is provided with a third through slot 310 , and an inner wall of the first through slot 301 connected to the extension plate 308 is provided with an extension slot 311 , and the third through slot 310 allows steel bars and concrete to pass through and enter the extension slot 311 .

[0067] By providing the third through groove 310 for the steel bars to pass through, the limiting plate 304 is restricted from being separated from the second through groove 305 and the strength of the concrete inside the first through groove 301 is further enhanced, thereby enhancing the stability of the connection between the two shear walls.

[0068] A plurality of air holes 312 communicating with the outside of the connecting sleeve 202 are disposed on the inner side walls of the grouting groove 303 and the extension groove 311 , and the air holes 312 are inclinedly disposed in a direction deviating from the inner bottom of the extension groove 310 .

[0069] Ventilation is performed through the provided air holes 312, thereby accelerating the solidification speed of the concrete in the first through groove 301, the grouting groove 303 and the extension groove 311, and improving the assembly efficiency.

[0070] Furthermore, the air holes 312 are arranged in an inclined upward direction, thereby avoiding the problem that concrete protrudes through the air holes 312 and needs to be filled multiple times.

[0071] The inner bottom of the slot 302 and the end of the wedge-shaped plate portion 307 are both provided with magnetic attraction portions 313 that attract each other through magnetic force.

[0072] The magnetic attraction portion 313 is used to attract the wedge-shaped plate portion 307 , so as to prevent the limiting plate 304 from shifting during the concrete filling process to affect the fixing effect of the connecting plate 102 .

[0073] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
