Abstract
Description
Technical Field
[0001] This utility model relates to the field of building renovation technology, and in particular to a device for reinforcing exterior walls during building renovation construction. Background Technology
[0002] With the acceleration of urbanization, a large number of old buildings face the need for renovation and reinforcement to ensure their structural safety and extend their service life. Wall reinforcement is a crucial step in the exterior wall renovation process, directly affecting the overall stability and wind and earthquake resistance of the building. Currently, common exterior wall reinforcement methods on the market mostly involve adding reinforced concrete beams or columns or directly fixing them to the wall with anchors. While these methods can enhance wall strength to some extent, they have drawbacks such as long construction periods, high costs, and significant damage to the original structure. Especially when the original wall materials are aged and severely cracked, traditional reinforcement methods struggle to effectively penetrate and evenly distribute the reinforcement force, easily leading to poor reinforcement results or localized stress concentration. Utility Model Content
[0003] The purpose of this utility model is to provide a device for reinforcing the exterior wall during building renovation to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a wall reinforcement device for building renovation construction, comprising a composite material layer, steel beams and a support, wherein the composite material layer comprises a substrate layer, a surface layer and an inner layer, two steel beams are provided on the outer side of the composite material layer, prestressed anchors are provided on the outer side of the steel beams, wall bolts are installed through the prestressed anchors, a support member is provided on the outer side of the steel beams, and a bracket is provided at the bottom of the support member.
[0005] Preferably, the surface layer is disposed on one side of the substrate layer, and the inner layer is disposed on the other side of the substrate layer.
[0006] Preferably, the wall bolt is made of steel.
[0007] Preferably, a positioning bolt is installed through the bottom of the bracket.
[0008] In summary, this application includes the following beneficial technical effects:
[0009] This utility model mainly consists of a composite material layer, a steel beam, prestressed anchors, and supporting components. It adopts a modular design, which makes on-site installation simple and quick, greatly shortening the construction cycle. By directly attaching the composite material layer to the surface of the wall to be reinforced, the excellent tensile strength and lightweight properties of the composite material layer can be utilized to effectively improve the overall strength of the wall. The prestressed anchors are ingeniously designed, causing minimal damage to the original wall during construction, which is conducive to protecting the historical features of the building.

[0015] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0016] Example 1: A wall reinforcement device for building renovation construction includes a composite material layer 1, steel beams 2 and a support 5. The composite material layer 1 includes a base layer 101, a surface layer 102 and an inner layer 103. Two steel beams 2 are provided on the outer side of the composite material layer 1. Prestressed anchors 3 are provided on the outer side of the steel beams 2. Wall bolts 301 are installed through the prestressed anchors 3. Support members 4 are provided on the outer side of the steel beams 2. The support 5 is provided at the bottom of the support members 4.
[0017] The substrate layer 101 is made of glass fiber reinforced polymer, the surface layer 102 is made of UV-resistant material, such as PET film, and the inner layer 103 is made of moisture-proof film. By using them together, the service life of the substrate layer 101 can be effectively increased, and the stability of the composite material layer 1 can be guaranteed. The steel beam 2 can restrict the installation position of the composite material layer 1. The wall bolts 301 on the prestressed anchor 3 penetrate the wall and form a firm connection with the inside of the wall. By firmly fixing the steel beam 2, the prestressed reinforcement effect is achieved. The use of the support 4 and the bracket 5 can further reinforce the steel beam 2 and the composite material layer 1.
[0018] Reference Figure 4 The surface layer 102 is disposed on one side of the substrate layer 101, and the inner layer 103 is disposed on the other side of the substrate layer 101. The surface layer 102 and the inner layer 103 can protect the substrate layer 101 and extend its service life. During installation, the surface layer 102 is exposed to more sunlight, and the surface layer 102 has UV protection properties, which can prevent aging.
[0019] Reference Figure 2 The wall bolt 301 is made of steel. During installation, the wall bolt 301 can penetrate the wall surface to achieve prestressed reinforcement.
[0020] Reference Figure 3 A positioning bolt 501 is installed through the bottom of the bracket 5. The positioning bolt 501 can be inserted into the ground to fix the position of the bracket 5 so as to provide stable support for the steel beam 2.
[0021] The implementation principle of this application embodiment is as follows: This device mainly consists of a composite material layer 1, a steel beam 2, prestressed anchors 3, and a support 4. During construction, the wall is first cleaned and surface-treated to ensure that the composite material layer 1 is evenly laid and well bonded to the wall. Then, the steel beam 2 is installed and fixed by the prestressed anchors 3. The steel beam 2 allows the composite material layer 1 to be directly attached to the surface of the wall to be reinforced. The support 4 is in contact with the steel beam 2, and the installation position of the support 4 is supported by the bracket 5. This further supports and fixes the installation positions of the steel beam 2 and the composite material layer 1. (In specific construction operations, the bracket 5 and the support 4 can be omitted to improve aesthetics.) The excellent tensile strength and lightweight properties of the composite material layer 1 effectively improve the overall strength of the wall.
