Description

Technical Field

[0001] This utility model relates to the field of construction, specifically to an insulated exterior wall panel with embedded parts. Background Technology

[0002] Traditional building wall panels and floor slabs are typically made of solid reinforced concrete slabs. However, due to their poor thermal insulation performance, buildings using solid reinforced concrete slabs often suffer from significant energy losses. To improve the thermal insulation effect of buildings, precast concrete sandwich wall panels have emerged. Precast concrete sandwich wall panels mainly consist of concrete leaf slabs on both sides, an insulation board in the middle, and steel bars connecting the concrete leaf slabs on both sides. When a building wall panel also serves as a building curtain wall, it is often necessary to attach decorative or functional components to the curtain wall. If anchor bolts are directly drilled into the concrete leaf slabs of the wall panel, the limited thickness of the concrete slabs cannot meet the anchor bolt embedment depth requirements, and the edges of the slabs are prone to cracking when drilling near the edges of the concrete leaf slabs, making it unable to withstand the long-term load or wind vibration effects of the attached components.

[0003] To avoid drilling holes in the concrete leaf slabs, existing building wall panels are constructed by pre-embedding a set of steel plates on the outer leaf slab surface. These steel plates serve as installation platforms, and external components are installed after drilling holes. However, with this pre-embedded steel plate structure, the load of the external components may still be directly applied to the concrete outer leaf slab through the pre-embedded steel plates. Over time, this can easily lead to panel deformation or detachment, failing to guarantee the stable installation of external components on the building curtain wall and posing a safety hazard. Therefore, this issue urgently needs to be addressed. Utility Model Content

By setting embedded parts, this utility model connects and fixes the embedded steel plate to the reinforcing bars within the building wall panel, allowing the load of the external components to be transferred to the wall panel body through the reinforcing bars, thus ensuring the stable installation of the external components on the building curtain wall.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An insulated exterior wall panel with embedded parts includes a concrete outer leaf panel, an insulation board, and a concrete inner leaf panel arranged in sequence. An outer steel plate serving as an installation platform is provided on the surface of the concrete outer leaf panel away from the insulation board. The surface of the outer steel plate has installation holes for the embedded parts to pass through and be positioned. A guide channel is provided in the embedded parts for the positioning of reinforcing bars. The outer steel plate, the concrete outer leaf panel, the insulation board, and the concrete inner leaf panel are connected by reinforcing bars.

[0007] As a further embodiment of this utility model: the embedded part includes a base, and at least two sets of guide sections arranged parallel to the axis of the base are provided on the base. The guide sections are bendable, and the outer ring of the guide sections is provided with barb sections. The barb sections and the base clamp and position the outer steel plate. Each guide section is arranged in a circumferential array around the axis of the base, and the guide sections enclose each other to form a guide channel for the reinforcing bars to pass through.

[0008] As a further embodiment of this utility model: an inner steel plate is provided on the side of the inner concrete leaf plate adjacent to the insulation board. The inner steel plate has installation holes at the corresponding positions of the outer concrete leaf plate for the installation of embedded parts. The reinforcing bars pass through the embedded parts on the inner steel plate and the outer steel plate in a direction perpendicular to the surface of the insulation board.

[0009] As a further improvement of this utility model: an insulation layer is provided on the surface of the inner steel plate and the adjacent barbed sections of the outer steel plate, and the insulation layer is clamped and positioned by the barbed sections.

[0010] As a further improvement of this utility model: the mounting holes on the inner steel plate and the outer steel plate are all two-section holes. One section of the mounting hole is a tapered hole whose diameter gradually narrows along the direction close to the barb section. The other section of the mounting hole is a cylindrical hole connected to the small diameter section of the tapered hole. The base of the embedded part corresponds to the size of the tapered hole, and each guide section of the embedded part corresponds to the size of the cylindrical hole.

[0011] As a further improvement of this utility model: the reinforcing bar is an FRP reinforcing bar, and the inner wall of each guide section of the embedded part is provided with internal threads, and the reinforcing bar is positioned in conjunction with the threads of each guide section.

[0018] 2. The multi-segment design of the embedded part of this utility model allows the guide segment to bend and pass through the installation hole of the steel plate. The base of the embedded part and the hook segment clamp and position the steel plate, thereby fixing the embedded part to the steel plate before pouring. By setting an internal thread structure in the inner ring of the guide segment, the steel bar and the embedded part are installed and fixed by the thread, thereby adjusting the installation depth of the steel bar.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 In this embodiment of the present invention, an insulated exterior wall panel with embedded parts includes an outer concrete leaf panel 1, an insulation board 2, and an inner concrete leaf panel 3 arranged sequentially from the outside to the inside.

An outer steel plate 4 and an inner steel plate 7 are respectively provided on the surface of the outer concrete leaf panel 1 away from the insulation board 2 and on the surface of the inner concrete leaf panel 3 adjacent to the insulation board 2.

[0027] Mounting holes are provided on the surfaces of both the outer steel plate 4 and the inner steel plate 7. The mounting holes are funnel-shaped two-section holes. Taking the outer steel plate 4 as an example, one section of the mounting hole is a tapered hole whose diameter gradually narrows along the direction of the adjacent insulation board 2, and the other section of the mounting hole is a cylindrical hole. The end of the cylindrical hole is connected to the small diameter section of the tapered hole.

[0028] Embedded parts 5 are installed in the mounting holes of the outer steel plate 4 and the inner steel plate 7. The embedded parts 5 include a base 51 and guide sections 52. The base 51 is conical, corresponding to the conical hole size of the mounting hole. At least two sets of guide sections 52 are provided at the ends of the base 51. The guide sections 52 are arc-shaped, corresponding to the cylindrical hole diameter of the mounting hole. The guide sections 52 are arranged in a circumferential array around the axis of the base 51, and the guide sections 52 form a guide channel for the reinforcing bar 8 to pass through. An opening is made at the center of the base 51, and the size of the opening corresponds to the size of the guide channel.

[0029] The inner wall of the guide section 52 is threaded, and the reinforcing bar 8 is preferably an FRP reinforcing bar, which is threadedly engaged with the guide section 52 for fixation. During actual processing, the center hole of the base 51 is also threaded, allowing the base 51 to thread with the reinforcing bar 8. The length of the guide section 52 is usually slightly greater than the length of the cylindrical hole of the mounting hole. A barb section 53 is provided on the outer ring of the end of the guide section 52 that protrudes from the mounting hole. The shape of the barb of the barb section 53 is not limited; after bending the guide section 52 to pass through the mounting hole, the barb section 53 abuts against the surface of the steel plate. In actual operation, the barb section 53 and the base 51 clamp and position the steel plate, thereby fixing the installation position of the embedded part 5. At least two sets of embedded parts 5 are provided on both the outer steel plate 4 and the inner steel plate 7. Each set of embedded parts 5 corresponds to a set of reinforcing bars 8 within the wall panel. The two embedded parts 5, the outer concrete leaf plate 1, the insulation board 2, and the inner concrete leaf plate 3 are connected by the reinforcing bars 8.

[0030] To mitigate the thermal bridging effect, insulation layers 6 are provided on the surfaces of adjacent barbed sections 53 of both the outer steel plate 4 and the inner steel plate 7. The insulation layers 6 can be fixed to the plate surface by adhesive or clamped and positioned by the barbed sections 53.

The dimensions of the embedded parts 5 on the outer steel plate 4 and the inner steel plate 7 correspond to the thickness of the steel plates.

[0031] In this embodiment, when the sandwich wall panel is used as a building curtain wall, the thickness of the outer concrete leaf panel 1 is 60mm, the thickness of the insulation board 2 is 30mm, and the thickness of the inner concrete leaf panel 3 is 200mm.
