Description

Technical Field

[0001] The utility model belongs to the technical field of assembled buildings, and in particular relates to a left and right side broken bridge fixing piece for doors and windows suitable for various wall widths. Background Art

[0002] IPS (Integrated Precast Shearwall) wall is an integrated prefabricated shear wall system, which is constructed by the traditional method of pouring concrete. It has the advantages of fast construction speed, controllable quality, and good seismic performance. It consists of a protective layer, an insulation layer, and a structural layer. The protective layer and the structural layer are both cast-in-place reinforced concrete structures, and the insulation layer uses insulation boards. During construction, when installing door and window frames on IPS walls with door and window openings, the door and window frames and the insulation board layer or reinforced concrete layer of the wall cannot be reliably and effectively fixed, which seriously affects the construction quality and poses a safety hazard to construction.

[0003] The Chinese patent (CN 219316769U) previously applied by the inventor discloses a fixing connector for door and window frames of prefabricated buildings, which is pre-buried in the wall and can effectively and reliably fix the left and right sides of the door and window frames. However, with the development of prefabricated buildings, the thickness of the current IPS energy-saving wall will also change accordingly according to the requirements of different regions and different use environments. When the thickness of the protective layer and the structural layer changes, it is necessary to design and manufacture door and window thermal break fixings of different lengths and specifications, and different specifications of door and window thermal break fixings require the design and manufacture of molds of different specifications, resulting in high mold costs and high production costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a left and right side broken bridge fixing piece for doors and windows of various wall widths, which can be conveniently and accurately embedded in the wall, is conducive to reducing mold costs and reducing production costs.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a broken bridge fixing piece suitable for the left and right sides of doors and windows with various wall widths, including a vertical plate and a horizontal plate, wherein the vertical plate is provided with more than two horizontal reinforcement limiting grooves near both ends along the length direction of the plate body, and the horizontal plate is provided with longitudinal reinforcement limiting grooves corresponding to the horizontal reinforcement limiting grooves one by one; the vertical plate has broken openings between adjacent horizontal reinforcement limiting grooves and the horizontal plate has broken openings between adjacent longitudinal reinforcement limiting grooves.

[0006] As a preferred technical solution, the vertical plate and the horizontal plate are an integrally formed structure.

[0007] As a preferred technical solution, the vertical plate and the horizontal plate form an L-shaped structure.

[0008] As a preferred technical solution, a rib is provided between the back surface of the vertical plate and the bottom surface of the horizontal plate.

[0009] As a preferred technical solution, the height of the vertical plate gradually decreases from the middle to the two ends.

[0010] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0011] (1) The fixing connector includes a vertical plate and a horizontal plate. The vertical plate is provided with two or more horizontal reinforcement limit grooves near both ends along the length direction of the plate body. The horizontal reinforcement limit grooves can be conveniently positioned with the longitudinal reinforcements of the reinforcement trusses on both sides of the prefabricated wall insulation board layer. The horizontal plate is provided with longitudinal reinforcement limit grooves corresponding to the horizontal reinforcement limit grooves. The longitudinal reinforcement limit grooves can be conveniently positioned with the transverse reinforcements of the reinforcement trusses on both sides of the prefabricated wall insulation board layer. When the reinforced concrete layer is poured on both sides of the insulation board layer, a number of broken bridge fixing parts are arranged along the periphery of the door and window openings and are respectively positioned with the reinforcement trusses and then pre-buried in the wall, so as to facilitate the effective and reliable fixing of the door and window frames when installing them.

[0012] (2) The vertical plate has a break opening between adjacent transverse reinforcement limit grooves and the horizontal plate has a break opening between adjacent longitudinal reinforcement limit grooves, so that the break position can be selected according to the thickness of the wall, so that it can be applied to IPS walls of different thicknesses and meet different energy-saving requirements in different regions. The broken bridge fixing piece can be produced using a pair of molds, with low mold costs and low single-piece production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0019] like Figures 1 to 3 As shown, the left and right side broken bridge fixings suitable for doors and windows of various wall widths include a vertical plate 1 and a horizontal plate 2. The vertical plate 1 has more than two horizontal reinforcement limiting grooves 11 distributed along the length direction of the plate body near both ends. In this embodiment, four horizontal reinforcement limiting grooves 11 are used as an example for illustration. The horizontal reinforcement limiting grooves 11 can be used to facilitate positioning with the longitudinal reinforcements of the steel trusses on both sides of the prefabricated wall insulation board layer; the horizontal plate 2 is provided with longitudinal reinforcement limiting grooves 21 corresponding to the horizontal reinforcement limiting grooves 11. The longitudinal reinforcement limiting grooves 21 can be used to facilitate positioning with the transverse reinforcements of the steel trusses on both sides of the prefabricated wall insulation board layer.

[0020] refer to Figure 1 and Figure 2 The vertical plate 1 has a break opening 22 between adjacent transverse reinforcement limit grooves 11, and the horizontal plate 2 has a break opening 22 between adjacent longitudinal reinforcement limit grooves 21. In this way, different break positions can be selected or no break can be performed according to the thickness of the wall, so that it can be applied to IPS walls of different thicknesses and meet different energy-saving requirements in different regions. The broken bridge fixing piece can be produced by using a pair of molds, with low mold costs and low single-piece production costs.

[0021] The vertical plate and the horizontal plate preferably adopt an integrally formed structure, and can be made of a thermal insulation material such as nylon 66, epoxy resin, vinyl fiber, alkali-free glass fiber or basalt fiber to slow down the heat conduction effect.

[0022] refer to Figure 3 In order to facilitate the positioning operation during pre-embedding and ensure the pre-embedding effect, the vertical plate 1 and the horizontal plate 2 form an L-shaped structure, wherein the height of the vertical plate 1 gradually decreases from the middle to the two ends, which is convenient for operation and fixing during pre-embedding. A plurality of ribs 3 are arranged between the back of the vertical plate 1 and the bottom of the horizontal plate 2, and the ribs 3 can effectively play a role in fixing and strengthening.

[0023] refer to Figure 4When the reinforced concrete layers are poured on both sides of the insulation board layer of the prefabricated wall, a number of the thermal break fixings are arranged around the door and window openings (the window openings are used as an example in the figure) and are respectively positioned with the steel trusses 4 and then pre-buried in the wall. When the window frame 5 is installed, the window frame is connected to the thermal break fixings with screws, so as to facilitate the effective and reliable fixing of the window frame and ensure the construction quality of the prefabricated building.

[0024] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
