Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building template reinforcement, in particular to a reinforcement device for shear walls and upper inverted beam templates. Background Art
[0002] Building formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components into specified positions and geometric dimensions, maintain their correct position, and withstand the formwork's own weight and external loads. To ensure effective fixation during use, building formwork is generally used in conjunction with a support device. During shear wall construction, to prevent rebar from shifting during concrete pouring, it is necessary to lay out lines, drill holes, and plant rebar on the cast floor slab, or install prefabricated formwork fixtures on the cast floor slab. By inserting self-tapping screws into the corresponding panels and aligning them with the corresponding back-ribbed channel steel, the prefabricated shear wall reinforcement cage can be fixed to the panels, forming a single unit. Traditional shear wall construction requires the formwork to be disassembled and transported after the concrete has formed. This process takes one to two days to complete, wasting time and money. Fast-paced construction often results in poor quality of the cast-in-place concrete shear walls on both sides of the settlement joints, and the need for efficient material turnover during construction cannot be met.
[0003] When pouring underground shear walls, horizontal construction joints must be set. The first horizontal construction joint is set at a distance of approximately 500mm from the bottom plate surface, and a waterstop steel plate is installed at the construction joint. This shear wall, which is approximately 500mm from the bottom plate surface, must be poured together with the bottom plate. The usual practice is to use a hanging formwork. In order to fix the position and size of the hanging formwork, it must be reinforced with through-wall waterstop screws. There are three disadvantages of through-wall waterstop screws. First, they must remain in the shear wall after use, becoming a disposable component, which increases material costs. Second, the screw holes must be professionally sealed, which increases the risk of water seepage and construction difficulty. Third, the formwork must be punched, causing formwork wear. Many floor beams and roof beams have beam surfaces that protrude above the floor and roof, forming upturned beams. The upturned beams and the floor and roof must also be poured together. The usual practice is to use a standard formwork and also use through-wall waterstop screws for reinforcement, which has similar disadvantages. Utility Model Content

[0006] In one embodiment, the fixing portion is a detachable angle steel, and the angle steel includes a bottom plate and a vertical plate arranged along the bottom plate.
[0007] In one embodiment, the mounting portions are symmetrically arranged on the bottom plate and the vertical plate of the angle steel along the transverse axis of the angle steel, and the mounting portions of different fixing portions are symmetrically arranged.

[0016] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments described in 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.
[0017] The following is in conjunction with the instructions Figure 1 and attached Figure 2 , the structural design of this device is described in detail.
[0018] A reinforcement device for a shear wall and an upper inverted beam formwork comprises a pair of formworks 1 arranged opposite to each other, a concrete wall being formed in the area between the pair of formworks 1, an L-shaped fixing portion 2 being provided on the outer surface of the formworks 1 away from the concrete wall, and an installation portion 3 for installing a positioning rib being provided on the fixing portion 2 near the upper surface of the concrete wall, the installation portion 3 comprising a U-shaped groove 31 and a positioning hole 32, and the two fixing portions 2 being relatively fixed via the installation portion 3.
[0019] When the two fixing parts 2 overlap, the U-shaped grooves 31 on the different fixing parts 2 are pulled against each other by bolts, and the overlapping positioning holes 32 are fixed by bolts. The U-shaped grooves 31 can adapt the two fixing parts to concrete walls of different sizes, and at the same time ensure that the template 1 is reinforced within the error range.
[0020] Furthermore, in a preferred embodiment of the reinforcement device for a shear wall and an upper inverted beam formwork of the present invention, there are at least three positioning holes 32 , and different positioning holes 32 are arranged away from the U-shaped groove 31 .
[0021] The number of U-shaped grooves 31 and positioning holes 32 can be increased according to actual needs. The distances between different U-shaped grooves 31 and positioning holes 32 are set to be different. This facilitates the fixing of the template 1 and ensures that it can still be used normally under different errors.
[0022] Furthermore, in a preferred embodiment of the reinforcement device for a shear wall and an upper inverted beam formwork of the present invention, the fixing portion 2 is a detachable angle steel, and the angle steel includes a bottom plate 21 and a vertical plate 22 arranged along the bottom plate 21 .
[0023] Furthermore, in a preferred embodiment of a reinforcement device for a shear wall and an upper inverted beam formwork of the utility model, the mounting portion 3 is symmetrically arranged on the bottom plate 21 and the vertical plate 22 of the angle steel along the horizontal axis of the angle steel, and the mounting portions 3 of different fixing portions 2 are symmetrically arranged.
[0024] When the bottom plates 21 and the vertical plates 22 on different fixing parts 2 are fixed correspondingly, the pulling force on the mounting part 3 reaches the maximum, ensuring a more secure fixation.
[0025] Furthermore, in a preferred embodiment of the reinforcement device for shear walls and upper inverted beam formwork of the utility model, the fixing portion 2 is a square tube that can be sleeved in different sizes, and the mounting portion 3 is circumferentially arranged along the transverse axis of the square tube, and the mounting portions 3 of different fixing portions 2 are symmetrically arranged.
[0026] Furthermore, in a preferred embodiment of the present invention's reinforcement device for a shear wall and an upper inverted beam formwork, the fixing portion 2 includes a support portion, one end of which is fixedly connected to the bottom plate 21 of the angle steel, and the other end of the support portion 23 is fixedly connected to the joint between the fixing portion 2 and the formwork 1. The support portion strengthens the fixing portion 2 and prevents deformation, and a diagonal brace is added at the joint between the fixing portion 2 and the formwork 1.
[0027] The shear wall of the utility model can fix the prefabricated shear wall steel cage body and the panel by cooperating with the corresponding fixed angle steel without embedding the self-tapping screws into the corresponding panel. Different models of products are placed in corresponding positions. After the installation is completed, they are fixed by multiple positioning bolts. After the concrete reaches a certain strength, it is only necessary to remove the multiple fixed angle steels and multiple positioning bolts.
[0028] In summary, the present invention's shear wall and upper inverted beam formwork reinforcement device effectively positions and secures the formwork, ensuring the cross-sectional dimensions of the shear wall. It is also easy to operate and protects pre-buried pipelines from damage. It is reusable and easy to install and remove, helping to enhance the visual quality of the shear wall, increase the turnover rate of the formwork, improve construction efficiency, and reduce construction costs.
