Description

Technical Field

[0001] This utility model relates to a composite building wall panel. Background Technology

[0002] Building wall panels are a new type of wall material that has developed with the rise of prefabricated large-panel buildings. They are mainly used in the load-bearing system of building structures. They consist of interior walls and exterior walls. The interior walls mainly serve a load-bearing function and can be made of bricks, blocks, precast or cast-in-place concrete. The exterior walls mainly serve a decorative and moisture-proof function. According to the different materials and construction methods used, wall panel structures can be divided into two categories: prefabricated structures and cast-in-place structures.

[0003] The existing prefabricated building wall panels have large assembly gaps and a relatively loose overall structure. There is a lack of effective traction between the cast concrete inner wall and the outer wall, making them easy to separate under longitudinal external forces, resulting in poor load-bearing performance. Moreover, the manufacturing process involves casting the inner wall first and then fixing the insulation board and the outer wall to the inner wall in sequence, which is a complicated and time-consuming process, resulting in low production efficiency and requiring further improvement. Utility Model Content

[0004] In view of the current state of the prior art, the technical problem to be solved by this utility model is to provide a modular building wall panel that eliminates assembly gaps to improve the overall structural compactness and load-bearing capacity, while simplifying the manufacturing steps to achieve time-saving and labor-saving effects and improve manufacturing efficiency.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a composite building wall panel, characterized in that it includes a base plate, a heat insulation plate and a panel arranged sequentially from back to front and parallel to each other and fixed to each other, and also includes a rib mesh disposed between the base plate and the heat insulation plate.

[0006] It also includes multiple connectors evenly distributed between the base plate, the heat insulation plate and the panel, the connectors including screws vertically inserted in the base plate and internally threaded expansion tubes embedded in the back side of the panel;

[0007] The rear end of the screw is formed with a baffle, and the front end of the screw passes through the rib mesh and the heat insulation plate and is inserted into the internal thread expansion tube so that the baffle is pressed against the rear outer wall of the base plate.

[0008] The reinforcing mesh includes multiple transversely arranged weft steel bars distributed from top to bottom, and multiple vertically fixed longitudinal steel bars arranged from left to right among the multiple weft steel bars.

[0009] Preferably, each of the latitudinal reinforcing bars is further provided with a plurality of inner supports arranged sequentially from left to right. The inner supports include two V-shaped inner supports arranged symmetrically at the top and bottom, and the bend of each V-shaped inner support is inclined and fixed to the latitudinal reinforcing bar.

[0010] Preferably, the two ends of the upper V-shaped inner support bar in the inner support frame are both arranged facing backward and upward and are symmetrically distributed left and right and are both pressed against the front outer wall of the base plate, and the two ends of the lower V-shaped inner support bar in the inner support frame are both arranged facing backward and downward and are symmetrically distributed left and right and are both pressed against the front outer wall of the base plate.

[0011] Preferably, the connector further includes a guide sleeve embedded in the heat insulation plate and movably sleeved outside the screw, wherein an annular retaining ring is formed on the outer rear edge of the guide sleeve, and the annular retaining ring is attached to the outer rear wall of the heat insulation plate.

[0012] Preferably, both ends of the V-shaped inner support bar also form an outward arc-shaped bend, and the outer arc surface of each arc-shaped bend slides against the front outer wall of the base plate.

[0015] Preferably, a vertically oriented notch is provided on the right front edge of the panel, and correspondingly, an extension strip that cooperates with the notch is formed outward on the left front edge of the panel.

[0016] Compared with the prior art, the advantages of this utility model are as follows: This utility model uses multiple connectors to firmly combine the base plate, heat insulation board, panel and poured concrete core block together and press them together, thereby eliminating assembly gaps and improving the overall structure's compactness.

[0022] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0023] like Figures 1-3 As shown, a composite building wall panel includes a base plate 1, a heat insulation board 3, and a panel 4 arranged sequentially from back to front and parallel to each other and fixed to each other, and also includes a reinforcing mesh 2 disposed between the base plate 1 and the heat insulation board 3.

[0024] It also includes multiple connectors 5 evenly distributed between the base plate 1, the heat insulation plate 3 and the panel 4. The connectors 5 include screws 51 that are horizontally inserted in the base plate 1 and distributed perpendicular to the base plate 1, and internally threaded expansion tubes 53 embedded in the rear side of the panel 4.

[0025] The rear end of the screw 51 forms a baffle 511, and the front end of the screw 51 passes through the rib mesh 2 and the heat insulation plate 3 and is inserted into the internal thread expansion tube 53 so that the baffle 511 is pressed against the rear outer wall of the base plate 1, thereby fixing the base plate 1, the heat insulation plate 3 and the panel 4 together.

[0026] The reinforcing mesh 2 includes multiple transversely arranged weft steel bars 21 distributed sequentially from top to bottom, and multiple vertically fixed longitudinal steel bars 22 arranged sequentially from left to right among the multiple weft steel bars 21.

[0027] Each latitudinal reinforcing bar 21 is also provided with multiple inner supports 6 arranged sequentially from left to right. The inner supports 6 include two V-shaped inner supports 61 arranged symmetrically at the top and bottom. The bend of each V-shaped inner support 61 is inclined and fixed to the latitudinal reinforcing bar 21.

[0028] The two ends of the upper V-shaped inner support bar 61 in the inner support frame 6 are both set facing upward and backward and are symmetrically distributed on the left and right, and are both pressed against the front outer wall of the base plate 1. The two ends of the lower V-shaped inner support bar 61 in the inner support frame 6 are both set facing downward and backward and are symmetrically distributed on the left and right, and are both pressed against the front outer wall of the base plate 1.

[0029] The connector 5 also includes a guide sleeve 52 embedded in the heat insulation plate 3 and movably sleeved outside the screw 51. The outer edge of the rear end of the guide sleeve 52 forms an annular retaining ring 521, which is attached to the rear outer wall of the heat insulation plate 3.

[0030] Both ends of the V-shaped inner support bar 61 also form an arc-shaped bending section 611, and the outer arc surface of each arc-shaped bending section 611 slides and fits against the front outer wall of the base plate 1.

[0031] A limiting strip 62 is fixed between the left end of one V-shaped inner support bar 61 and the left end of another V-shaped inner support bar 61, and between the right end of one V-shaped inner support bar 61 and the right end of another V-shaped inner support bar 61.

[0032] Multiple first countersunk holes 11 are provided on the rear outer wall of the base plate 1. The number of first countersunk holes 11 is equal to the number of connectors 5. A first through hole 12 is provided between the center of the bottom surface of each first countersunk hole 11 and the front outer wall of the base plate 1. The screws 51 in each connector 5 are inserted into the corresponding first through hole 12 so that the retainer 511 on each screw 51 can be rotatably embedded in the corresponding first countersunk hole 11.

[0033] The heat insulation plate 3 has multiple second through holes 31, the number of which is equal to the number of connectors 5. The guide sleeve 52 in each connector 5 is embedded in a corresponding second through hole 31.

[0034] Multiple second countersunk holes 41 are provided on the rear outer wall of panel 4. The number of second countersunk holes 41 is equal to the number of connectors 5. The internal threaded expansion tube 53 in each connector 5 is embedded in a corresponding second countersunk hole 41.

[0035] A vertical notch 42 is provided on the right front edge of panel 4, and correspondingly, an extension strip 43 is formed outward on the left front edge of panel 4 to cooperate with the notch 42.

[0036] Working principle:

[0037] First, the base plate 1, heat insulation plate 3, and panel 4 are vertically placed into the mold and arranged sequentially from back to front. Then, the reinforcing mesh 2 is placed between the base plate 1 and the heat insulation plate 3. Next, the front end of the screw 51 in each connector 5 passes forward sequentially through the first through hole 12, the grid formed by the reinforcing mesh 2, and the guide sleeve 52. The screw 51 is rotated by the rotating baffle 511, so that the front end of the screw 51 is inserted into the internal thread expansion tube 53. The internal thread expansion tube 53 will slowly expand outward due to the continuous screwing of the screw 51, so that the internal thread expansion tube 53 is tightened in the second countersunk hole 41. Thus, the base plate 1, heat insulation plate 3, and panel 4 are fixed together by the connector 5. During this process, the base plate 1 gradually moves towards the panel 4, and the baffle 511 on the screw 51 will gradually embed into the first countersunk hole 11 to ensure the flatness of the rear outer wall of the base plate 1.

[0038] When the front outer wall of the base plate 1 contacts both ends of each V-shaped inner support strip 61, it will push the rib mesh 2 forward, thereby forcing the front outer wall of the heat insulation board 3 to gradually press against the rear outer wall of the panel 4. At the same time, the two ends of each V-shaped inner support strip 61 will slowly move away from each other under the pressure of the base plate 1 and press more firmly against the front outer wall of the base plate 1. The setting of the arc-shaped bending section 611 ensures that the two ends of the V-shaped inner support strip 61 will not stop moving away due to excessive friction.

[0039] Since the two ends of the upper V-shaped inner support bar 61 in the inner support frame 6 are both set facing upward and backward and are symmetrically distributed on the left and right, and the two ends of the lower V-shaped inner support bar 61 in the inner support frame 6 are both set facing downward and backward and are symmetrically distributed on the left and right and are both pressed against the front outer wall of the base plate 1, the two ends of the V-shaped inner support bar 61 will also move away from each other when they move away from each other, thereby causing each limiting bar 62 to gradually tighten, thus preventing the two ends of the V-shaped inner support bar 61 from separating excessively.

[0040] Finally, concrete is poured between the base plate 1 and the insulation board 3 and completely submerges the reinforcing mesh 2. After solidification, a concrete core block is formed between the base plate 1 and the insulation board 3. The concrete core block is then combined with the base plate 1, the insulation board 3 and the panel 4 through multiple connectors 5 to form a composite wall panel. The composite wall panel can then be removed from the mold.

[0041] During assembly, the extension strips 43 on the panel 4 of one of the composite wall panels are embedded in the notch grooves 42 on the panel 4 of the adjacent composite wall panel, so that the two adjacent composite wall panels can be seamlessly spliced.

[0042] This utility model uses multiple connectors 5 to firmly combine the base plate 1, heat insulation board 3, panel 4 and the poured concrete core block together and press them together, thereby eliminating assembly gaps and improving the overall structural compactness. Even under large longitudinal external forces, they will not separate, thus improving load-bearing performance. At the same time, the reinforcing mesh 2 is used to move the concrete pouring step to the end and achieve integral molding, thereby simplifying the manufacturing steps to achieve the effect of saving time and labor and improving manufacturing efficiency.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
