[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0022] Embodiment 1

[0023] AsFigures 1-3 As shown, an embodiment of the present utility model provides a frame-shaped precast wall panel, including a wall panel body. At least one side wall of the wall panel body is formed with a web groove, and a support structure is provided in at least part of the web groove. The support structure includes a support member 400 or a plurality of support members 400 distributed vertically in sequence. The support members 400 are respectively fixedly connected to opposite side walls of the web groove.

[0024] In the embodiment of the present utility model, by arranging the support structure in the web groove, the overall structural strength and stability of the frame-shaped precast wall panel can be effectively improved, the application reliability of the frame-shaped precast wall panel can be ensured, and the application range of the frame-shaped precast wall panel can be increased.

[0025] In one embodiment, as Figures 1-3 , the support member 400 is an X-shaped support member 400. Four end portions of the X-shaped support member 400 are respectively fixedly connected to opposite side walls of the web groove, and very high support reliability can be obtained.

[0026] In one embodiment, as Figures 1-6 , the wall panel body includes two frame-shaped plates 200 and a heat preservation plate 100 clamped between the two frame-shaped plates 200, so that the web grooves are respectively formed on both sides of the heat preservation plate 100.

[0027] In this embodiment, the heat preservation plate 100 is clamped between the two frame-shaped plates 200. While ensuring the performance such as the overall structural strength of the precast wall panel, the synchronous assembly of the heat preservation plate 100 and the frame-shaped plate 200 is realized. Therefore, the construction of the heat preservation layer in the precast wall panel is facilitated, and the heat preservation performance of the wall panel is ensured. The two frame-shaped plates 200 on both sides are completely separated by the heat preservation plate 100, and the problem of dealing with cold and heat bridges in the assembled building is reliably solved.

[0028] The above-mentioned frame-shaped plate 200 is generally a square plate, including a top border plate, a bottom border plate and two side border plates.

[0029] Optionally, as Figure 1 and Figure 2 , the support member 400 is connected to two opposite border plates of the corresponding frame-shaped plate 200. For this case, the above-mentioned support member 400 is preferably connected to the two side border plates.

[0030] Optionally, as Figure 3, at least one of the frame plates 200 is provided with a reinforcing bridge 500, and the reinforcing bridge 500 is fixedly connected to two opposite side plates 201 of the corresponding frame plate 200 respectively. For example, the vertical reinforcing bridge 500 is fixedly connected to the top and bottom side plates of the corresponding frame plate 200 respectively, and / or the horizontal reinforcing bridge 500 is fixedly connected to the two side plates of the corresponding frame plate 200 respectively. The above-mentioned reinforcing bridge 500 can adopt an L-shaped reinforcing plate / T-shaped reinforcing plate; it is preferably welded and fixed between the reinforcing bridge 500 and the side plate 201. The setting of the reinforcing bridge 500 can effectively improve the structural strength, stiffness and mechanical properties of the above-mentioned precast wall panel. This solution is particularly applicable to the case of large-format wall panels or wall panels with a relatively large height.

[0031] As Figure 3 , for the case where the reinforcing bridge 500 is provided, correspondingly, two abdominal grooves are formed on the corresponding side of the insulation board 100, and the support members 400 are arranged in both of the two abdominal grooves. The support member 400 can be an X-shaped support member 400 or a V-shaped support member 400. Among them, the two ends of the X-shaped support member 400 are fixedly connected to the side plate 201 opposite to the reinforcing bridge 500, and the other two ends are fixedly connected to the reinforcing bridge 500; the two ends of the V-shaped support member 400 are fixedly connected to the side plate 201 opposite to the reinforcing bridge 500, and the corner ends are fixedly connected to the reinforcing bridge 500.

[0032] In one embodiment, as Figure 4 , a plurality of U-shaped members 300 are arranged on each edge of the insulation board 100. The U-shaped members 300 are buckled on the corresponding edge of the insulation board 100, and each side plate 201 of the frame plate 200 is fixedly connected to the U-shaped member 300 on the corresponding edge of the insulation board 100 through a threaded fastener.

[0033] In one embodiment, as Figure 4 , a plurality of embedding grooves are arranged on each edge of the insulation board 100, and each of the U-shaped members 300 is correspondingly embedded in each of the embedding grooves. The embedding grooves are recessed on the edge of the insulation board 100. After the U-shaped members 300 are embedded, it is preferably to make the surface of the U-shaped members 300 coplanar with the surface of the insulation board 100, so that the frame plate 200 and the insulation board 100 can be fitted and connected. In addition, the embedding grooves can play a certain limiting and restraining role on the U-shaped members 300, improving the integral combination of the frame plate 200 and the insulation board 100.

[0034] The above U-shaped member 300 includes two parallel clamping plates and a connecting plate connecting the two clamping plates. Among them, the plate surfaces of the two clamping plates are parallel to the plate surface of the insulation board 100, and the two clamping plates are respectively in contact with the two side plate surfaces of the insulation board 100. The connecting plate is in contact with the edge end surface (top surface / bottom surface / two side surfaces of the insulation board 100) of the corresponding insulation board 100, so that the U-shaped member 300 is buckled on the corresponding edge of the insulation board 100.

[0035] Further, after the U-shaped member 300 is buckled on the insulation board 100, one or more bolts pass through the two clamping plates and are locked by nuts, which can ensure the connection reliability between the U-shaped member 300 and the insulation board 100, prevent the U-shaped member 300 from separating from the insulation board 100, and in particular can improve the cooperative stress-bearing performance of the two clamping plates, and further improve the cooperative stress-bearing performance of the two side frame plates 200. Among them, the bolt connection position is preferably located at the end of the clamping plate, that is, on the side away from the connecting plate, so that the connecting bolts can avoid the frame plate 200.

[0036] Preferably, a wire mesh skeleton is provided inside the above insulation board 100, which can improve the structural strength and stiffness of the insulation board 100; in particular, the structural strength and stress-bearing performance of the edge of the insulation board 100 can be improved by increasing the wire density of each edge of the insulation board 100, so as to ensure the bonding reliability with the U-shaped member 300 and the frame plate 200, and prevent defects such as cracking due to stress on the edge of the insulation board 100.

[0037] The above U-shaped member 300 can be a steel member or can be made of building composite materials. Further, stiffening ribs can be provided on the U-shaped member 300 to play roles such as increasing structural strength and stress-bearing performance.

[0038] Such as Figure 4 and Figure 6 , hollow grooves can be opened on the U-shaped member 300, which can reduce the weight of the insulation board 100 and the precast wall panel.

[0039] By buckling the U-shaped member 300 on the edge of the insulation board 100 and tightly connecting the U-shaped member 300 with the two side frame plates 200, the two side frame plates 200 are connected as a whole and cooperate in stress, which is convenient for the production of the heat-insulating precast wall panel.

[0040] Preferably, the above support member 400 is fixedly connected to the U-shaped member 300 on the corresponding vertical edge of the insulation board 100, which is convenient for the installation of the support member 400 and also realizes the fixed connection between the support member 400 and the opposite side groove walls of the abdominal groove.

[0041] In one embodiment, such as Figure 5 and Figure 6At least part of the frame plate 201 includes a first plate body 2011 and a second plate body 2012 vertically connected, the first plate body 2011 is in contact with the insulation board 100 and is fastened to the corresponding U-shaped member 300 through threaded fasteners, and the second plate body 2012 is located on the side of the first plate body 2011 away from the insulation board 100.

[0042] Optionally, at least part of the frame plate 201 is an L-shaped frame plate, and the end of the second plate body 2012 is connected to the end of the first plate body 2011, and the L-shaped frame plate can be made of angle steel. The frame plate 200 is preferably an integral structure, for example, four angle steels can be welded to form a frame structure, and of course, an integrally formed structure can also be used.

[0043] Among them, optionally, at least part of the frame plate 201 is a T-shaped frame plate, and the end of the first plate body 2011 can be connected to the middle of the second plate body 2012. In this case, the second plate body 2012 can be used to close the various edges of the prefabricated wall panel / the various edges of the insulation board 100 to further improve the structural strength and stress-bearing performance of the prefabricated wall panel; the end of the second plate body 2012 can also be connected to the middle of the first plate body 2011.

[0044] Optionally, at least part of the frame plate 201 is a cross-shaped frame plate, for example, the middle of the first plate body 2011 is connected to the middle of the second plate body 2012, and it has the functions of the above two T-shaped frame plates.

[0045] In another embodiment, Figure 2 At least part of each frame plate is a rectangular tube 202, and one side of the rectangular tube 202 is in contact with the insulation board 100. The rectangular tube 202 includes but is not limited to a steel tube.

[0046] Among them, the rectangular tube 202 includes relatively arranged installation side wall panels and wall side wall panels and relatively arranged outer edge side wall panels and inner edge side wall panels, and the installation side wall panels are in contact with the insulation board 100; the threaded fasteners pass through the wall side wall panels and the installation side wall panels in sequence and are fastened and connected with the corresponding U-shaped member 300; and / or, two parallel clamping plates of the U-shaped member 300 are respectively extended to form connecting wing plates, and the connecting wing plates are in contact with the corresponding inner edge side wall panels and the two are fixedly connected by the threaded fasteners.

[0047] The threaded fasteners are preferably self-tapping screws, but it is also a feasible solution to use bolts and connect two opposite frame plates on both sides of the insulation board 100 as a whole through the bolts.

[0048] The above-mentioned abdominal groove can be used for installing decorative panels and / or installing water and electricity pipelines, etc. Therefore, preferably, as Figure 6 , pipeline holes 2031 for the decoration pipelines to pass through are provided on at least part of the border board 201.

[0049] In addition, as Figure 6 , assembly holes 2032 for assembling and connecting with other building components are provided on at least part of the border board 201, and the assembly connection between the building components is preferably through bolt assembly.
