Description

Technical Field

[0001] The present invention relates to the technical field of shear walls, and specifically to a space truss constrained plate steel shear wall. Background Art

[0002] A shear wall is a wall in a building or structure that mainly bears the horizontal load and vertical load (gravity) caused by wind load or earthquake action, preventing the structure from shear (shearing) failure. It is divided into plane shear walls and tube shear walls. Plane shear walls are used in reinforced concrete frame structures, lift slab structures, and flat slab floor systems. Tube shear walls are used in high-rise buildings, high-rise structures, and suspended structures, surrounded by the partition walls of elevator shafts, stairwells, equipment, and auxiliary rooms. The tube walls are all cast-in-place reinforced concrete walls, and their stiffness and strength can withstand greater horizontal loads compared to plane shear walls.

[0003] A truss is a structure formed by connecting rods hinged to each other at both ends. A truss is generally a planar or spatial structure composed of straight rods with triangular units. The truss rods mainly bear axial tension or compression, so that the strength of the material can be fully utilized. When the span is relatively large, it can save materials compared to a solid web beam, reduce self-weight, and increase stiffness. Commonly used ones include steel trusses, reinforced concrete trusses, prestressed concrete trusses, wooden trusses, steel-wood composite trusses, and steel-concrete composite trusses.

[0004] For a space truss, the axes of the truss rods and the external forces they receive are not in the same plane. In engineering, some space trusses cannot be simplified as plane trusses for treatment, such as grid structures, tower structures, and crane structures. The joints of space trusses are smooth spherical hinge joints, and the axes of the rods all pass through the spherical hinge center of the joint and can rotate around any axis of the spherical hinge center. Each joint has three degrees of freedom in space.

[0005] A patent document with the publication number CN107143059B, a space truss constrained plate steel shear wall, designs the traditional external constraint member as a space three-dimensional truss constraint plate, which is arranged in two rows, upper and lower, and the front and rear truss constraint plates are connected by edge connecting rods. This not only ensures the out-of-plane stability of the internal energy dissipation core plate, but also has a simpler structure than the traditional external constraint member, a clear force transmission, and is convenient for design and processing;

[0006] At the same time, this space truss constraint plate replaces the traditional external constraint member, improves its economic benefits, reduces the self-weight of the steel shear wall structure. By connecting through the reserved channels of the steel bars passing through the steel channels instead of the traditional welding and bolt connection methods, it not only facilitates its factory batch production and speeds up the construction progress, but also provides great convenience for the daily maintenance and repair of the steel shear wall.

[0007] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0008] This space truss - constrained plate - type steel plate shear wall adopts the form of arranging truss - constrained plates on both sides of the energy - dissipating core plate, which can facilitate construction and ensure the stability of the energy - dissipating core plate. However, in the actual application process, since both the front and rear of the energy - dissipating core plate are supported and restricted by the truss - constrained plates, while ensuring the structural strength and stability of the truss - constrained plates themselves, it greatly increases the thickness of the finally constructed steel plate shear wall and is likely to occupy a relatively large amount of indoor space. Summary of the Invention

[0009] In order to overcome the deficiencies of the existing space truss - constrained plate - type steel plate shear wall in the actual application process, that is, since both the front and rear of the energy - dissipating core plate are supported and restricted by the truss - constrained plates, while ensuring the structural strength and stability of the truss - constrained plates themselves, it greatly increases the thickness of the finally constructed steel plate shear wall and is likely to occupy a relatively large amount of indoor space. The embodiment of the present application provides a space truss - constrained plate - type steel plate shear wall. By using multiple constraint frames to form a constraint truss, and each constraint frame is composed of four bar - shaped bars A and bar - shaped bars B to form a rectangular box surface. When assembling the constraint frame outside the energy - dissipating core plate, the bar - shaped bar B on the constraint frame passes through the inside of the inclined slot, and the bar - shaped bar A passes through the inside of the straight slot, which can support the energy - dissipating core plate and fix it inside the constraint frame. Without affecting the overall structure of the constraint truss, the internal support structure is sandwiched inside the constraint truss, greatly reducing the thickness of the shear wall and the space it occupies.

[0010] The technical solution adopted by the embodiment of the present application to solve its technical problems is:

[0011] A space truss - constrained plate - type steel plate shear wall includes a constraint truss and an internal support structure, and the internal support structure is sandwiched inside the constraint truss;

[0012] The constraint truss includes multiple constraint frames, and the internal support structure includes multiple energy - dissipating core plates;

[0013] Among them, multiple constraint frames are laid flat to form the main structure of the shear wall, and multiple energy - dissipating core plates are assembled flat inside multiple constraint frames and remain in a fixed state with multiple constraint frames.

[0014] In a possible implementation, each of the multiple constraint frames includes twelve bar - shaped bars A and six bar - shaped bars B; four bar - shaped bars A are assembled into a rectangular box, and one bar - shaped bar B is diagonally pulled into the inside of the four bar - shaped bars A, dividing the rectangular box into two triangles.

[0015] In a possible implementation, the constraint frame is assembled into a cube by twelve bar - shaped bars A and six bar - shaped bars B, and adjacent two constraint frames share the same rectangular box, making multiple constraint frames in an integrated state.

[0016] In a possible implementation, straight grooves are processed at the centers of the four sides, at the four corners, and at the center point of the energy-consuming core plate. Two diagonal grooves are processed at each of the four sides of the energy-consuming core plate. The diagonal grooves also extend to the center point of the energy-consuming core plate, and there are four of them.

[0017] In a possible implementation, four of the restraint frames correspond to one energy-consuming core plate. A plurality of bar-shaped rods A perpendicular to the surface of the energy-consuming core plate on the four restraint frames are respectively located inside a plurality of straight grooves, and a plurality of bar-shaped rods B passing through the inside of the energy-consuming core plate are respectively located inside a plurality of diagonal grooves.

[0018] In a possible implementation, the energy-consuming core plate forms a triangle with the edge of the restraint frame parallel to the energy-consuming core plate through the bar-shaped rod B passing through the inside of the diagonal groove, restricting its forward and backward movement inside the restraint frame.

[0019] In a possible implementation, two clamping slots are processed at each of the four sides of the energy-consuming core plate, and a connecting and fixing member is arranged between the clamping slots where two adjacent energy-consuming core plates are joined.

[0020] In a possible implementation, the two clamping slots located at one side of the energy-consuming core plate are respectively located on both sides of the straight groove at this side, and the connecting and fixing member is located inside the rectangular frame formed by the four bar-shaped rods A and bar-shaped rods B.

[0021] In a possible implementation, the connecting and fixing member includes a strip plate, and fixing columns are integrally formed at both sides of the strip plate; the two fixing columns are respectively pinned inside the two adjacent clamping slots, and the two energy-consuming core plates are connected together through the strip plate.

[0022] The beneficial effects of this application are as follows:

[0023] First, in this solution, by using a plurality of restraint frames to form a restraint truss, and each restraint frame is formed by a rectangular frame composed of four bar-shaped rods A and bar-shaped rods B. When assembling the restraint frame outside the energy-consuming core plate, the bar-shaped rod B on the restraint frame passes through the inside of the diagonal groove, and the bar-shaped rod A passes through the inside of the straight groove, which can support the energy-consuming core plate and fix it inside the restraint frame. Without affecting the overall structure of the restraint truss, the internal support structure is sandwiched inside the restraint truss, greatly reducing the thickness of the shear wall and the space it occupies;

[0024] Second, in this solution, by processing clamping grooves at the four edges of the energy-dissipating core plate and pinning the connection fixing parts between the clamping grooves where two adjacent energy-dissipating core plates meet, two adjacent energy-dissipating core plates can be connected and fixed, which is beneficial to the assembly work of the entire internal bracing structure. When passing the strip-shaped rod B through the inclined strip groove, the front-back movement of the energy-dissipating core plate inside the restraint frame can be restricted, ensuring the structural strength of the energy-dissipating core plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0032] Embodiment 1:

[0033] This embodiment introduces the specific structure of a space truss restrained plate steel shear wall, specifically referring to Figures 1 - 3 , Figure 5 shown, including a restraint truss 2 and an internal bracing structure 1 sandwich arranged inside the restraint truss 2. The restraint truss 2 includes a plurality of restraint frames 201, and the internal bracing structure 1 includes a plurality of energy-dissipating core plates 101. Each of the plurality of restraint frames 201 includes twelve strip-shaped rods A2011 and six strip-shaped rods B2012;

[0034] Among them, by assembling four bar-shaped rods A2011 into a rectangular frame and obliquely pulling one bar-shaped rod B2012 into the interior of the four bar-shaped rods A2011, the rectangular frame can be divided into two triangles. When assembling the cube constraint frame 201 with twelve bar-shaped rods A2011 and six bar-shaped rods B2012, the structural strength of the constraint frame 201 can be ensured;

[0035] Secondly, when the constraint frame 201 is assembled into a cube by twelve bar-shaped rods A2011 and six bar-shaped rods B2012, and the same rectangular frame is shared between two adjacent constraint frames 201, making multiple constraint frames 201 in an integral state can support the main structure of the shear wall formed by the planar laying of multiple constraint frames 201. After multiple energy dissipation core plates 101 are assembled into the interiors of multiple constraint frames 201 in a plane and fixed to the multiple constraint frames 201, the overall structural strength during the application of the shear wall can be ensured. Compared with the prior art, the use of one constraint truss 2 is cancelled, greatly reducing the space occupation;

[0036] Such as Figure 2 shown, straight grooves 4 are processed at the centers of the four sides, at the four corners, and at the center point of the energy dissipation core plate 101, and two inclined grooves 5 are processed at the four sides of the energy dissipation core plate 101;

[0037] Among them, the inclined grooves 5 are also processed to the center point of the energy dissipation core plate 101 and there are four of them. By making four constraint frames 201 correspond to one energy dissipation core plate 101, multiple bar-shaped rods A2011 perpendicular to the surface of the energy dissipation core plate 101 on the four constraint frames 201 are respectively located inside the multiple straight grooves 4, and multiple bar-shaped rods B2012 passing through the interior of the energy dissipation core plate 101 are respectively located inside the multiple inclined grooves 5, which can ensure that the energy dissipation core plate 101 can be sandwiched inside the constraint frame 201;

[0038] At the same time, by making the bar-shaped rod B2012 pass through the inclined groove 5 inside the energy dissipation core plate 101 and forming a triangle with the edge of the constraint frame 201 parallel to the energy dissipation core plate 101, the forward and backward movement of the energy dissipation core plate 101 inside the constraint frame 201 can be restricted, ensuring that the energy dissipation core plate 101 is fixed inside the constraint frame 201.

[0039] The above design forms the restraint truss 2 by using multiple restraint frames 201. Each restraint frame 201 is formed by four bar-shaped bars A2011 and bar-shaped bars B2012 to form a rectangular frame as the surface. When assembling the restraint frame 201 outside the energy dissipation core plate 101, the bar-shaped bars B2012 on the restraint frame 201 pass through the inside of the inclined slot 5, and the bar-shaped bars A2011 pass through the inside of the straight slot 4, which can support the energy dissipation core plate 101 to be fixed inside the restraint frame 201. Without affecting the overall structure of the restraint truss 2, the internal support structure 1 is sandwiched inside the restraint truss 2 to ensure the overall structural strength of the finally formed shear wall;

[0040] At the same time, compared with the way that both the front and back of the internal support structure 1 are supported by the restraint truss 2 in the prior art, the way of sandwiching and fixing the internal support structure 1 inside the restraint truss 2 greatly reduces the thickness of the shear wall and the occupied space without affecting the structural strength of the shear wall.

[0041] Embodiment 2:

[0042] Based on Embodiment 1, as Figure 2 and Figure 4 shown, this embodiment introduces the specific structure of the energy dissipation core plate 101. Two clamping slots 3 are processed at each of the four sides of the energy dissipation core plate 101, and a connection fixing member 102 is arranged between the clamping slots 3 where two adjacent energy dissipation core plates 101 are joined;

[0043] The connection fixing member 102 includes a strip plate 1022, and fixing columns 1021 are integrally formed at both sides of the strip plate 1022;

[0044] Among them, by making the two clamping slots 3 at one side of the energy dissipation core plate 101 be located on both sides of the straight slot 4 at this side, when the connection fixing member 102 is installed inside the clamping slot 3, the connection fixing member 102 can be located inside the rectangular frame formed by the four bar-shaped bars A2011 and bar-shaped bars B2012, and there will be no interference with the bar-shaped bars A2011 and bar-shaped bars B2012;

[0045] At the same time, by respectively pin-connecting the two fixing columns 1021 to the inside of the two adjacent clamping slots 3 and connecting the two energy dissipation core plates 101 together through the strip plate 1022, multiple energy dissipation core plates 101 can be assembled into a plate shape. When the bar-shaped bar B2012 passes through the inclined slot 5 inside the energy dissipation core plate 101 to form a triangle with the edge of the restraint frame 201 parallel to the energy dissipation core plate 101 to limit the forward and backward movement of the energy dissipation core plate 101 inside the restraint frame 201, the impact resistance of the energy dissipation core plate 101 can be ensured.

[0046] The above design processes clamping grooves 3 at the four sides of the energy-consuming core plate 101, and pins the connecting and fixing member 102 between the clamping grooves 3 where two adjacent energy-consuming core plates 101 are joined (the two fixing columns 1021 are respectively pinned inside the two joined clamping grooves 3, and the strip plate 1022 is connected between the two fixing columns 1021), so that two adjacent energy-consuming core plates 101 can be connected and fixed, which is beneficial to the assembly work of the entire internal bracing structure 1. When passing the strip-shaped rod B2012 through the diagonal slot 5, the front-back movement of the energy-consuming core plate 101 inside the restraint frame 201 can be restricted, ensuring the structural strength of the energy-consuming core plate 101.

[0047] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
