Description

Technical Field

[0001] The utility model relates to the technical field of shear walls, in particular to a shock-proof shear wall structure. Background Technique

[0002] A shear wall, also known as a wind-resistant wall, seismic wall or structural wall, is used to bear the horizontal load caused by wind load or seismic action in a building or structure. The shear wall can effectively prevent the building structure from being damaged by shear. At present, although the prefabrication rate of the fully prefabricated shear wall structure is relatively high, there are many longitudinal and transverse stirrups in the confined edge members of the shear wall, the connection structure of the prefabricated assembly joints is relatively complex, and the construction difficulty is relatively large. The edge members still adopt the cast-in-place form, which reduces the prefabrication rate and the firmness strength of the structure. At the same time, due to the cumbersome connection, the on-site engineering quantity is relatively large, and the advantages are not obvious compared with the cast-in-place shear wall structure.

[0003] For example, the patent publication number CN 204435604 U discloses a shock-proof shear wall structure, which includes a main wall body, an inner-expanded wall poured on the inner side of the main wall body, and an outer-expanded wall poured on the outer side of the main wall body; the main wall body includes a main wall steel bar framework and concrete poured in the main wall steel bar framework. The main wall steel bar framework includes a plurality of first column steel bar cages, a plurality of second column steel bar cages and a plurality of main wall steel bar cages. The plurality of first column steel bar cages and the plurality of second column steel bar cages are arranged in one-to-one correspondence. Adjacent two first column steel bar cages are connected by a first reinforcing rib, adjacent two second column steel bar cages are connected by a second reinforcing rib, and the first column steel bar cage and the second column steel bar cage are correspondingly connected by a third reinforcing rib. A main wall steel bar cage installation space is formed between the first reinforcing rib, the second reinforcing rib and adjacent two third reinforcing ribs. The construction method of the shock-proof shear wall structure is simple and fast, the construction speed is improved, the structural stability is good, the shock-proof effect is good, and it is convenient to popularize and use.

[0004] When the above patent is used, there are still some problems. The connection relationship of each group of structures is unstable, and the use strength during earthquake resistance cannot be guaranteed. Therefore, a shock-proof shear wall structure is needed now. Content of the Utility Model

[0005] The purpose of the utility model is to provide a shock-proof shear wall structure, which improves the use strength of the shear wall by setting a stress main body structure. At the same time, multiple groups of reinforcing steel bars arranged inside the connecting wall panel and the stress outer wall panel can also assist the stress main body structure to improve the seismic capacity of the shear wall, so as to solve the problems raised in the above background technique.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an earthquake-proof shear wall structure, comprising a load-bearing main structure, connecting wall panels are arranged on both sides of the load-bearing main structure, load-bearing external wall panels are arranged outside the connecting wall panels, and a plurality of groups of reinforcing steel bars are equidistantly arranged between the connecting wall panels and the load-bearing external wall panels;

[0007] The load-bearing main structure comprises a plurality of groups of main steel bars arranged at equal distances, each group of the main steel bars comprises three groups of main steel bars placed at equal distances, and two groups of staggered tensioning steel bars are staggeredly welded between each group of the main steel bars;

[0008] A group of cross-staggered steel bars is symmetrically arranged between two adjacent groups of reinforcing steel bars.

[0009] Preferably, the staggered tensioning steel bar group includes tensioning steel bars welded and installed between the middle main steel bar in the main steel bar group and the main steel bars on both sides in two adjacent main steel bar groups, and the welded tensioning steel bars have a certain inclination angle, and each group of tensioning steel bars in the same group of staggered tensioning steel bar group are staggered welded.

[0010] Preferably, the middle parts of the four groups of main steel bars in two adjacent groups of main steel bars are connected and installed by connecting wire sleeves, and auxiliary connecting wire sleeves are sleeved on the outer sides of the corresponding groups of staggered tensioning steel bars.

[0011] Preferably, two groups of positioning sleeves are sleeved on the inner and outer main steel bar surfaces of each group of main steel bar groups, and a group of auxiliary force-bearing plates are commonly installed on the outer ends of the two groups of positioning sleeves. The auxiliary force-bearing plates are bolted and installed in contact with the surface of the wall panels.

[0012] Preferably, a group of positioning blocks are respectively installed at the four ends of the cross-staggered steel bars, and an arc groove is opened on the outer end surface of each group of the positioning blocks corresponding to the reinforcing steel bars. A connecting plug plate is fixedly installed on the outer end surface of the positioning block located on one side of the arc groove, and a strength is opened on the outer end surface of the positioning block located on the other side of the arc groove. The two adjacent groups of cross-staggered steel bars are installed on the outside of the reinforcing steel bars through the mutual insertion and cooperation of the positioning blocks.

[0013] Preferably, the inner walls of the two groups of connecting wall panels are poured with a first pouring cement, and the interiors of the connecting wall panels and the load-bearing exterior wall panels are poured with a second pouring cement.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The overall strength of the force-bearing main structure in use is ensured by multiple groups of equally spaced main steel bars arranged inside the force-bearing main structure. At the same time, since each group of force-bearing main structures is sleeved with each other through connecting wire sleeves and auxiliary connecting wire sleeves, and each group of main steel bar brackets is supported and connected with each other through a staggered tensioning steel bar group, and the set staggered tensioning steel bar group pulls the main steel bars on both sides by the main steel bar in the middle. And because the staggered tensioning steel bar group is staggered and pulled on both sides in a triangular shape, the central main steel bar is stressed to tighten the staggered tensioning steel bar groups on both sides to further strengthen the force-bearing main structure, improving the central force-bearing strength of the shear wall, and thus better improving the seismic strength of the shear wall.

[0016] 2. Each group of strengthening steel bars arranged between the connecting wall panel and the force-bearing exterior wall panel are initially positioned and connected through the cooperation of cross-shaped staggered steel bars and positioning blocks. At the same time, since the cross-shaped staggered steel bars support the adjacent strengthening steel bars, the force-bearing strength on the outside of the shear wall is further improved, thereby enhancing the seismic strength of the shear wall.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides: a shock-proof shear wall structure, as Figures 1-6 shown, which includes a stress-bearing main structure 1. Connecting wall panels 9 are arranged on both sides of the stress-bearing main structure 1. A stress-bearing outer wall panel 10 is arranged outside the connecting wall panels 9. A number of groups of reinforcing bars 11 are arranged at equal intervals between the connecting wall panels 9 and the stress-bearing outer wall panel 10. The stress-bearing main structure 1 includes a number of groups of main reinforcing bar groups arranged at equal intervals. Each group of main reinforcing bar groups includes three main reinforcing bars 2 placed at equal intervals. Two groups of staggered tensioning bar groups 4 are welded between adjacent groups of main reinforcing bar groups. A group of cross-shaped staggered reinforcing bars 12 are symmetrically arranged up and down between adjacent two groups of reinforcing bars 11.

[0026] Preferably, the staggered tensioning bar group 4 includes tensioning bars welded and installed between the middle main reinforcing bar 2 in the main reinforcing bar group and the two side main reinforcing bars 2 in adjacent two groups of main reinforcing bar groups. And the welded tensioning bars have a certain inclination angle. The tensioning bars in the same group of staggered tensioning bar groups 4 are staggered and welded. By setting the staggered tensioning bar group 4 to pull and position adjacent two groups of main reinforcing bar groups, the connectivity of the main reinforcing bars 2 between adjacent two groups of main reinforcing bar groups is improved. At the same time, since the staggered tensioning bar group 4 is welded at an angle, the welding will form a staggered triangle, which further improves the seismic resistance between each group of main reinforcing bars 2.

[0027] Further, the middle parts of the four corresponding main reinforcing bars 2 in adjacent two groups of main reinforcing bar groups are sleeved and installed through connecting wire sleeves 3. And auxiliary connecting wire sleeves 5 are sleeved at the outer side positions corresponding to each group of staggered tensioning bar groups 4. The connecting wire sleeves 3 sleeved at the middle parts of each group of main reinforcing bars 2 and the auxiliary connecting wire sleeves 5 sleeved on both sides can cooperate with the staggered tensioning bar group 4 to further define the relationship between adjacent two groups of main reinforcing bar groups, to ensure the connectivity of the main reinforcing bars 2, further improve the service strength of the stress-bearing main structure 1, and ensure the seismic strength of the overall shear wall.

[0028] Furthermore, two positioning sleeves 6 are sleeved on the surfaces of the inner and outer main reinforcing bars 2 of each group of main reinforcing bar groups. A group of auxiliary stress-bearing plates 7 are jointly installed at the outer ends of the two positioning sleeves 6. The auxiliary stress-bearing plates 7 are bolted and installed on the surface of the connecting wall panel 9 in a fitting manner. The positioning sleeves 6 limit the auxiliary stress-bearing plates 7, and the auxiliary stress-bearing plates 7 are bolted to the connecting wall panel 9, so that there is a certain connectivity between the stress-bearing main structure 1 and the two side connecting wall panels 9 before pouring the first pouring cement 8, and the connectivity is further improved after pouring the first pouring cement 8, to expand the seismic effect.

[0029] It should be noted that a set of positioning blocks 13 are respectively installed at the four ends of the cross-shaped intersecting steel bars 12. An arc-shaped groove 14 is provided on the outer end face of each set of positioning blocks 13 corresponding to the reinforcing steel bars 11. A connecting plug board 15 is fixedly installed on the outer end face of the positioning block 13 on one side of the arc-shaped groove 14. A notch is provided on the outer end face of the positioning block 13 on the other side of the arc-shaped groove 14. The adjacent two sets of cross-shaped intersecting steel bars 12 are installed outside the reinforcing steel bars 11 through the mutual plug-in cooperation of the positioning blocks 13. The set cross-shaped intersecting steel bars 12 are limited by the positioning blocks 13, and the matching connection relationship between the cross-shaped intersecting steel bars 12 and the reinforcing steel bars 11 is ensured, greatly improving the service strength of the connecting wall panel 9 and the stressed exterior wall panel 10, and reducing the assembly difficulty to ensure the convenience of shear wall pouring.

[0030] Specifically, the first pouring cement 8 is poured on the inner walls of the two connecting wall panels 9, and the second pouring cement 17 is poured inside the connecting wall panel 9 and the stressed exterior wall panel 10. The pouring of the first pouring cement 8 and the second pouring cement 17 improves the overall service strength of the shear wall and greatly improves the seismic property of the shear wall.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
