[0002] Prefabricated components of prefabricated buildings are characterized by factory prefabrication and quick installation. Prefabricated walls of prefabricated buildings with steel structures usually include a middle insulation board layer and cast reinforced concrete layers on both sides (the cast reinforced concrete layers are prefabricated with steel trusses). During construction, when installing door and window frames on prefabricated walls of prefabricated buildings with door and window openings, the door and window frames cannot be reliably and effectively fixed to the insulation board layer or reinforced concrete layer of the prefabricated wall, 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 prefabricated building door and window frame fixing connector, which is pre-buried in the wall and can effectively and reliably fix the left and right sides of the door and window frame. However, due to structural design reasons, the fixing connector cannot fix the upper and lower ends of the door and window frame, which affects the construction quality. Therefore, further research and development is needed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an assembled building door and window upper and lower end broken bridge fixing piece which has a reasonable structural design and is convenient for effectively fixing the upper and lower ends of the door and window frames during construction, thereby improving the construction quality.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: the upper and lower ends of the prefabricated building door and window are broken bridge fixing parts, including a bottom fixing plate, and two vertical plates are fixedly arranged on the upper part of the bottom fixing plate, one end of the vertical plate is provided with an outer steel bar positioning part, and the other end of the vertical plate is provided with an inner steel bar positioning part.

[0006] As a preferred technical solution, the outer steel bar positioning portion is an outer transverse steel bar slot that can be engaged with the transverse steel bars of the outer steel bar truss.

[0007] As a preferred technical solution, an outer protective layer limiting portion is formed on the vertical plate and protrudes outwardly from the outer side of the outer transverse rib slot.

[0008] As a preferred technical solution, the inner steel bar positioning portion is an inner transverse reinforcement groove that can abut against the transverse reinforcement of the inner steel bar truss.

[0009] As a preferred technical solution, an inner protective layer limiting portion is formed on the vertical plate and protrudes from the inner side of the inner transverse rib abutment groove.

[0010] As a preferred technical solution, a rib plate is connected between the two vertical plates.

[0011] As a preferred technical solution, the inner steel bar positioning portion is provided with a locking plate for locking the transverse steel bars of the inner steel bar truss with the rib plate.

[0012] As a preferred technical solution, the locking plate includes a plate body, which is provided with an inner transverse reinforcement groove that is clamped with the transverse reinforcement of the inner reinforcement truss, and locking holes are respectively opened on the upper and lower sides of the inner transverse reinforcement groove on the plate body.

[0013] Due to the adoption of the above technical solution, the utility model has the following beneficial effects: the fixing part includes a bottom fixing plate, two vertical plates are fixedly arranged on the upper part of the bottom fixing plate, one end of the vertical plate is provided with an outer steel bar positioning part, and the other end of the vertical plate is provided with an inner steel bar positioning part, and the outer steel bar positioning part can be conveniently positioned with the transverse steel bars of the steel bar truss on the outer side of the prefabricated wall insulation board layer, and the inner steel bar positioning part can be conveniently positioned with the transverse steel bars of the steel bar truss on the inner side of the prefabricated wall insulation board layer; the locking plate can improve the overall positioning effect. When the reinforced concrete layer is poured on both sides of the insulation board layer, a number of the fixing parts are arranged along the upper and lower ends of the door and window openings, and are respectively positioned with the steel bar trusses and then pre-buried in the wall. The pre-buried fixing parts can effectively and reliably fix the upper and lower ends of the door and window frames, which is conducive to improving the construction quality and efficiency.

[0022] like Figure 1 and Figure 2 As shown, the upper and lower end thermal break fixings of the assembled building doors and windows are preferably made of thermal break materials, including a bottom fixing plate 1, and two vertical plates 2 are fixedly arranged on the upper part of the bottom fixing plate 1, one end of the vertical plate 2 is provided with an outer steel bar positioning part, and the other end of the vertical plate is provided with an inner steel bar positioning part.

[0023] refer to Figure 1 and Figure 2 In this embodiment, the outer steel bar positioning portion is an outer transverse bar groove 5 that can be engaged with the transverse steel bars 3 of the outer steel bar truss; the inner steel bar positioning portion is an inner transverse bar groove 6 that can abut against the transverse steel bars 4 of the inner steel bar truss. The outer transverse bar groove 5 can be conveniently engaged with the transverse steel bars 3 of the prefabricated outer steel bar truss, and the inner transverse bar groove 6 can be conveniently abutted with the transverse steel bars 4 of the inner steel bar truss.

[0024] The outer side of the outer transverse reinforcement groove 5 on the vertical plate 2 is formed with an outer protective layer limiter 7; the inner side of the inner transverse reinforcement groove 6 on the vertical plate 2 is formed with an inner protective layer limiter 8. The outer protective layer limiter 7 and the inner protective layer limiter 8 at both ends of the vertical plate can ensure that the template and the steel bar maintain a set distance H during the wall pouring construction, effectively block the point thermal bridge caused by the connector, reduce energy loss, and ensure that the thickness of the protective layer during pouring meets the design specification requirements.

[0025] refer to Figure 1A rib plate 9 is connected between the two vertical plates 2. The rib plates 9 arranged at intervals can play a reinforcing role on the one hand. On the other hand, it is convenient to cooperate with the locking plate 10. The locking plate 10 is arranged at the inner steel bar positioning part. The transverse steel bars 4 of the inner steel bar truss can be locked and fixed with the rib plate 9 through the locking plate 10.

[0026] refer to Figure 3 and Figure 4 The locking plate 10 includes a plate body 11, on which an inner transverse reinforcement groove 12 is provided for clamping with the transverse reinforcement 4 of the inner reinforcement truss. Locking holes 13 are respectively provided on the upper and lower sides of the inner transverse reinforcement groove 12 of the plate body 11. When the inner transverse reinforcement groove 6 on the vertical plate 2 is in contact with the transverse reinforcement 4 of the inner reinforcement truss, the locking plate 10 and the rib plate 9 are bolted to achieve effective fixation of the integral fixing member and the inner reinforcement truss.

[0027] refer to Figure 5 The fixing parts are pre-buried at the upper and lower ends A along the door and window openings (the window openings are used as an example in the figure). When the doors and windows 20 are installed, the upper and lower ends of the door and window frames are respectively fixed to the bottom fixing plates 1 of the fixing parts pre-buried in the prefabricated wall with double self-drilling screws. On the one hand, the door and window frames can be effectively and reliably fixed. On the other hand, relevant energy-saving requirements can be met without installing additional frames, which is conducive to improving construction quality and efficiency.

[0028] 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.
