Description

Technical Field

[0001] The utility model relates to the technical field of shear walls, in particular to a shear wall opening reinforcement structure. Background Art

[0002] Shear walls are also called wind-resistant walls, earthquake-resistant walls or structural walls. They are walls in houses or structures that mainly bear horizontal and vertical loads caused by wind loads or earthquakes to prevent structural shear damage. They are usually made of reinforced concrete. Shear walls have door openings and window openings for lighting and building functions. However, openings will greatly reduce the bearing capacity of the shear walls in the original structure. Therefore, it is very important to take reinforcement measures to ensure the stability of the structure after openings in the shear walls.

[0003] After searching, a patent document with publication number "CN111794552B" discloses a large-area rear opening reinforcement structure of a shear wall, which includes a plurality of first carbon fiber cloths and a plurality of second carbon fiber cloths pasted to the inner side walls of the opening, and each inner side wall of the opening is provided with fixing plates on both sides along the thickness direction of the opening, and each fixing plate is provided with a torsion spring on the side close to the opening, and each fixing plate is connected to a stabilizing plate through the torsion spring; the fixing plate is in contact with the second carbon fiber cloth located on the outer wall of the shear wall, and the stabilizing plate is in contact with the first carbon fiber cloth and the second carbon fiber cloth located on the inner side wall of the opening.

[0004] In the above-mentioned prior art, since the plates of the reinforcement structure are large and the structure is relatively complex, although a good reinforcement effect can be achieved, the construction time is relatively long. The reinforcement construction of the shear wall openings needs to be completed in time to avoid the impact of the openings on the overall performance of the shear wall. Therefore, a shear wall opening reinforcement structure is needed. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] refer to Figure 1-4 A shear wall opening reinforcement structure shown includes a shear steel 1 and a connecting piece; the shear steel 1 is provided with multiple and evenly spaced distribution around the shear wall opening; the shear steel 1 is a U-shaped steel section, the shear steel 1 covers the shear wall opening and is snap-fitted with the front and rear walls of the shear wall; the multiple shear steels 1 are fixed to each other by connecting steel components 2 to form an integrated whole; the shear steel 1 is provided with an anchor fixed to the shear wall.

[0030] Based on the above structure, by setting the reinforced steel sections as multiple sections of small-sized attached steel 1, the installation of the reinforced structure is made more flexible and convenient. At the same time, a plurality of attached steels 1 are connected into a whole using a connecting steel assembly 2, so that the reinforced structure has good integrity and ensures its supporting performance. Secondly, anchors are used to anchor the attached steel 1 on the shear wall, so that the reinforced structure and the shear wall form a unified whole, ensuring the effectiveness of the support. The use of the reinforced structure can not only realize the reinforced support of the shear wall opening, but also facilitate the installation and disassembly of the reinforced structure, thereby achieving the purpose of speeding up the construction.

[0031] Further, the connecting member includes a connecting steel component 2, and the connecting steel component 2 includes a panel 21 and a hinge plate 22. The panel 21 fits the peripheral side of the shear wall opening and is located between two adjacent attached steels 1. Two hinge plates 22 are provided and are respectively fixed to the front and rear sides of the panel 21. The side walls of the two hinge plates 22 that are close to each other are respectively in contact with the outer walls of the front and rear sides of the attached steel 1.

[0032] The two hinge plates 22 are detachably fixedly connected via a fixing piece.

[0033] By setting the panel 21 and the hinge plate 22, two adjacent attached steels 1 can be connected as a whole, and multiple attached steels 1 can be connected into an integral frame support structure by using multiple connecting steel components 2, which can facilitate the rapid installation of the reinforcement structure at the opening of the shear wall to reinforce and support the shear wall.

[0034] Furthermore, the fixing part includes a through-penetrating anchor rod 23. The through-penetrating anchor rod 23 can adopt an anchor rod structure commonly used in the prior art and suitable for the present embodiment, such as a limiting structure composed of a screw and a nut or an anchor rod with limiting structures at both ends. One end of the through-penetrating anchor rod 23 passes through the two hinge plates 22 and the attached steel 1 and is simultaneously penetrated in the shear wall. By setting the through-penetrating anchor rod 23, the two hinge plates 22 can be tightly connected between the two attached steels 1, so that the two attached steels 1 are connected as a whole.

[0035] Furthermore, the panel 21 is clamped between two adjacent attached steels 1, and the left and right side walls of the panel 21 are respectively abutted against the side walls of the two attached steels 1 that are close to each other. Through the arrangement of the panel 21, the gap between the two attached steels 1 can be filled, so that a plane is formed around the shear wall opening, which is convenient for subsequent construction and modification of the shear wall opening.

[0036] Furthermore, the side panels of the attached steel 1 are in a gradually expanding trapezoidal structure, and the hinge plate 22 is in a trapezoidal structure that is adapted to and opposite to the side panels of the attached steel 1. By setting the attached steel 1 to have a gradually expanding trapezoidal structure with side panels, the strength of the attached steel 1 to withstand vertical and lateral forces is enhanced, and vertical and lateral deformation of the attached steel 1 due to force can be avoided to a large extent, thereby enhancing the stability of the reinforced structure and achieving a good reinforcement and support effect.

[0037] Furthermore, the anchoring piece includes a welding anchor block 4, which is welded and penetrated on the attached steel 1 and fixed to the attached steel 1, and one end of the welding anchor block 4 is fixed to the fracture of the embedded wall steel bar 3 at the opening of the shear wall. Through the setting of the welding anchor block 4, the embedded wall steel 1 and the embedded wall steel bar 3 in the shear wall can be fixedly connected. While fixing the attached steel 1, the fracture of the embedded wall steel bar 3 is welded for corrosion protection, thereby protecting the embedded wall steel bar 3 inside the shear wall, avoiding damage to the fracture of the embedded wall steel bar 3 inside the shear wall caused by the opening, thereby enhancing the protection of the shear wall.

[0038] Example 2

[0039] A shear wall opening reinforcement structure is different from Example 1 in that: two hinge plates 22 are provided and are respectively hinged to the front and rear sides of the panel 21, so that the angle between the panel 21 and the hinge plate 22 can be adjusted, and the installation is more flexible and convenient.

[0040] Working principle of the utility model: in daily use, firstly, vertical holes are opened around the opening of the shear wall, so that the vertical holes correspond to the fractures of the pre-embedded steel bars 3 in the wall, and at the same time, transverse holes are opened through the front and rear sides of the shear wall, so that the transverse holes avoid the pre-embedded steel bars 3 in the wall; then, the enclosed steel 1 is clamped around the opening of the shear wall, and the enclosed steel 1 and the pre-embedded steel bars 3 in the wall are welded by welding anchor blocks 4 to fix the enclosed steel 1, then, the panel 21 is clamped between two adjacent enclosed steels 1, and two hinge plates 22 are covered on the outside of the enclosed steel 1, and then, the anchor rods 23 are inserted through the transverse holes to fix the two hinge plates 22 and two adjacent enclosed steels 1 together, so that a plurality of enclosed steels 1 and a plurality of connecting steel components 2 form an integral supporting frame structure;

[0041] By configuring the reinforced steel sections to be multiple sections of small-sized attached steel 1, the installation of the reinforced structure is made more flexible and convenient. At the same time, a plurality of attached steels 1 are connected into a whole using a connecting steel assembly 2, so that the reinforced structure has good integrity and its supporting performance is ensured. Secondly, anchors are used to anchor the attached steel 1 to the shear wall, so that the reinforced structure and the shear wall form a unified whole, thereby ensuring the effectiveness of the support. The use of the reinforced structure can not only realize the reinforced support of the shear wall opening, but also facilitate the installation and disassembly of the reinforced structure, thereby achieving the purpose of speeding up the construction.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
