Description

Technical Field

[0001] The utility model relates to the field of wall panels, in particular to an assembled spliced ​​wall panel. Background Art

[0002] Prefabricated buildings are different from traditional construction methods. The biggest feature of prefabricated buildings is that the building components (such as floor slabs, wall panels, etc.) are processed and manufactured in the factory, then transported to the construction site, and assembled and installed on site through reliable connection methods. Therefore, a reasonable and reliable connection method between two interconnected prefabricated parts is the basis for ensuring the stability of the building.

[0003] The Chinese utility model patent with publication number CN219710566U discloses a spliced ​​wall panel for assembled housing. The patent discloses a connection and fixing method of the wall panel, but it is necessary to install screws, turbines and other parts in the wall panel, which will obviously make the construction cost of the entire building too high. The Chinese utility model patent with publication number CN219710821U discloses a spliced ​​integrated wall panel, which simplifies the connection and fixing method of the wall panel, but the connecting parts are mainly concentrated at the top or bottom of the wall panel, so it is not suitable for wall panels with too large size, otherwise its stability cannot be guaranteed.

[0004] Based on this, it is necessary to improve the existing spliced ​​wall panels. Utility Model Content

[0006] Technical solution: To achieve the above purpose, the utility model discloses an assembled spliced ​​wall panel, comprising:

[0007] A first wall panel and a second wall panel butted against each other, the first wall panel being provided with a first recess and a second recess, the second wall panel being provided with a third recess and a fourth recess, the first recess, the second recess, the third recess and the fourth recess being all provided on the butt joint surface of the first wall panel and the second wall panel, the first recess and the third recess being butt jointed to form a first groove, the second recess and the fourth recess being butt jointed to form a second groove;

[0008] a plate body, the plate body being inserted into the first groove;

[0009] A sleeve, wherein the sleeve is disposed on the butt joint surface of the first wall panel and the second wall panel, and the opening of the sleeve faces the butt joint surface of the first wall panel and the second wall panel;

[0010] A tie bolt is screwed into the sleeve, and the annular portion of the tie bolt extends into the second groove and is inserted into the pull rod.

[0011] Furthermore, a gap is left between the first wall panel and the second wall panel.

[0012] Furthermore, the first groove, the second groove and the gap are filled with micro-expansive concrete.

[0013] Furthermore, a chamfer is left at the joint between the first wall panel and the second wall panel, a sealing strip is arranged inside the chamfer, and a structural adhesive is filled outside the chamfer.

[0014] Furthermore, the board body is a polyurethane insulation board.

[0015] Furthermore, the pull rod is a plain round steel bar.

[0016] Further, the second concave portion is disposed on both sides of the first concave portion, the fourth concave portion is disposed on both sides of the third concave portion, and the second groove is disposed on both sides of the first groove.

[0017] The utility model discloses an assembled spliced ​​wall panel, which has the following technical effects:

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1 To Attachment Figure 4 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0026] An assembled spliced ​​wall panel comprises a first wall panel 1, a second wall panel 2, a panel body 9, a sleeve 10 and tie bolts 11.

[0027] The first wall panel 1 and the second wall panel 2 are arranged side by side and butted against each other on the left and right. The first wall panel 1 is provided with a first recess 3 and a second recess 4, and the second wall panel 2 is provided with a third recess 5 and a fourth recess 6, on the butt joint surfaces of the first recess 3, the second recess 4, the third recess 5 and the fourth recess 6. After the first wall panel 1 and the second wall panel 2 are butt jointed, the first recess 3 and the third recess 5 are butt jointed to form a first recess 7, and the second recess 4 and the fourth recess 6 are butt jointed to form a second recess 8. In this embodiment, the first recess 7 is provided with two second recesses 8, and the two second recesses 8 are disposed on both sides of the first recess 7. Specifically, the number of the first recess 3, the second recess 4, the third recess 5 and the fourth recess 6 can be determined according to the specific heights of the first wall panel 1 and the second wall panel 2. The greater the height of the first wall panel 1, the greater the number of the first recess 3 and the second recess 4; the greater the height of the second wall panel 2, the greater the number of the third recess 5 and the fourth recess 6. The plate body 9 is a polyurethane heat-insulating plate. The plate body 9 extends into the first groove 7 and penetrates into the first wall panel 1 and the second wall panel 2 .

[0028] The sleeve 10 is fixed to the first wall panel 1 and the second wall panel 2 in a pre-embedded manner, and the sleeve 10 is disposed on both sides of the plate body 9. The sleeve 10 is a threaded steel sleeve, and the sleeve 10 is provided with an internal thread. The opening of the sleeve 10 faces the butt joint surface of the first wall panel 1 and the second wall panel 2. The structure of the tie bolt 11 is shown in the attached figure. Figure 4 As shown, the tie bolt 11 is divided into a rod portion and a circular ring portion, wherein the rod portion of the tie bolt 11 is screwed into the sleeve 10, and the circular ring portions of the tie bolt 11 installed in the first wall panel 1 and the second wall panel 2 are aligned with each other. After the first wall panel 1 and the second wall panel 2 are butt-jointed, the circular ring portion of the tie bolt 11 extends into the second groove 8 and is inserted into the tie rod 12, and the tie rod 12 is preferably a plain round steel bar.

[0029] When the first wall panel 1 and the second wall panel 2 are spliced, a gap should be left between the butt joint surfaces, and the gap is preferably 5mm (with a tolerance of 0.05mm); after splicing, the plate body 9 and the tie rod 12 are inserted; finally, the first groove 7 and the second groove 8 and the gap are filled with micro-expansion concrete 13. Chamfers 14 are provided at the edges of the first wall panel 1 and the second wall panel 2, and a sealing strip 15 is provided inside the chamfer 14. The chamfer 14 is filled with structural adhesive 16 to smooth the chamfer 14. In this embodiment, the structural adhesive 16 is a weather-resistant silicone adhesive.

[0030] In the device, the plate body 9, the sleeve 10, the tie bolts 11 and the tie rods 12 are used to realize the splicing and fixing of the first wall panel 1 and the second wall panel 2, which has low construction cost and high applicability.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
