Description

Technical Field

[0001] The present application relates to the technical field of fireproof boards, and particularly relates to an assembled splicing structure for fireproof boards. Background Art

[0002] A fireproof board is a board made of fireproof materials (such as one or more of materials like glass wool, perlite, or calcium carbonate fiber, etc.), which has good fireproof performance and is widely used in building parts such as building walls, ceilings, and stairs to improve the overall fireproof ability of the building.

[0003] During the installation and construction process of the fireproof board, construction workers will connect two fireproof boards. Connection through holes are provided on the fireproof board, and the construction workers pass bolts through the connection through holes and then use nuts to achieve fixation, thereby realizing the connection and fixation of adjacent two fireproof boards.

[0004] However, when carrying nuts to the site for installation and construction, the nuts may fall off, affecting the installation efficiency. Moreover, when the size of the fireproof board is large (for example, the height of the fireproof board is higher than the height of a person), the construction workers' hands cannot operate the bolts and nuts simultaneously. Therefore, construction workers are required on both sides of the fireproof board to operate the bolts and nuts respectively, which also affects the installation efficiency. Based on this, the present application proposes an assembled splicing structure for fireproof boards. Utility Model Content

[0005] The present application provides an assembled splicing structure for fireproof boards. Through the threaded connection between the bolts and the threaded sleeves, the fixed connection between the first convex plate and the second convex plate is realized. The threaded sleeves are fixed on the first convex plate, and there is no risk of falling. Moreover, the construction workers only need to screw the bolts into the threaded sleeves from one side of the second convex plate, without the need to arrange personnel to operate on both sides of the fireproof board body, thereby ensuring the installation efficiency.

[0006] To solve the above technical problems, the present application adopts the following technical solutions:

[0007] An assembled splicing structure for fireproof boards includes a fireproof board body, a plurality of threaded sleeves, and a plurality of bolts. A first convex plate is provided at the first end of the fireproof board body. The first convex plate is provided with a plurality of mounting holes. A second convex plate is provided at the second end of the fireproof board body. The second convex plate is provided with a plurality of through holes, and the positions of the plurality of through holes correspond to the positions of the plurality of mounting holes. Adjacent two fireproof board bodies are assembled through the first convex plate and the second convex plate. The number of the plurality of threaded sleeves is equal to the number of the plurality of mounting holes, and the plurality of threaded sleeves are fixedly connected to the plurality of mounting holes in a one-to-one correspondence. The number of the plurality of bolts is equal to the number of the plurality of threaded sleeves, and the plurality of bolts pass through the through holes and are in mating connection with the threaded sleeves in a one-to-one correspondence.

[0008] When connecting two adjacent fireproof board bodies, the first convex plate and the second convex plate are opposed to each other so that the through hole corresponds to the threaded sleeve. Then, a bolt is passed through the through hole and screwed into the threaded sleeve to achieve the threaded connection between the bolt and the threaded sleeve, thereby realizing the fixed connection between the first convex plate and the second convex plate.

[0009] Compared with the prior art, the assembled splicing structure of this fireproof board realizes the fixed connection between the first convex plate and the second convex plate through the threaded connection between the bolt and the threaded sleeve. The threaded sleeve is fixed on the first convex plate, so there is no risk of falling. Moreover, the construction workers only need to screw the bolt from one side of the second convex plate, and there is no need to arrange personnel to operate on both sides of the fireproof board body, thus ensuring the installation efficiency.

[0010] In an embodiment of the present application, the installation hole is provided with a plurality of grooves evenly distributed along its circumferential direction, and the outer wall of the threaded sleeve is provided with a plurality of ribs evenly distributed along its circumferential direction. The number of the plurality of ribs is equal to and corresponds to the number of the plurality of grooves one by one.

[0011] In an embodiment of the present application, glue is coated between the threaded sleeve and the installation hole.

[0012] In an embodiment of the present application, a receiving groove is provided at one end of the through hole away from the threaded sleeve, and the receiving groove is used to receive the tail of the bolt.

[0013] In an embodiment of the present application, the first convex plate is provided with a guiding rib, and the second convex plate is provided with a guiding groove, and the guiding groove is matched with the guiding rib.

[0014] In an embodiment of the present application, the cross section of the guiding rib is trapezoidal.

[0015] In an embodiment of the present application, the thicknesses of both the first convex plate and the second convex plate are half of the thickness of the fireproof board body.

[0016] In an embodiment of the present application, the wall thickness of the threaded sleeve is at least 5 mm. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] An embodiment of the present application provides a prefabricated splicing structure for a fireproof board. As Figure 1 shown, it includes a fireproof board body 100, a plurality of threaded sleeves 200, and a plurality of bolts 300. Among them, the fireproof board body 100 is a component for achieving fire prevention, and the threaded sleeves 200 and bolts 300 can be used in cooperation to achieve the connection of two components.

[0030] As Figure 2 and Figure 3 shown, a first convex plate 110 is provided at the first end of the fireproof board body 100. The first convex plate 110 is provided with a plurality of mounting holes 120, and the plurality of mounting holes 120 are evenly arranged along the width direction of the fireproof board body 100. Figure 2 Three mounting holes 120 are shown. In implementation, the number of mounting holes 120 can be adjusted according to actual circumstances and is not limited herein.

[0031] As Figure 2 and Figure 3 shown, a second convex plate 130 is provided at the second end of the fireproof board body 100. The second convex plate 130 is provided with a plurality of through holes 140, and the plurality of through holes 140 are evenly arranged along the width direction of the fireproof board body 100. Figure 3 Three through holes 140 are shown. In implementation, the number of through holes 140 can be adjusted according to actual circumstances and is not limited herein.

[0032] As Figure 1 shown, adjacent two fireproof board bodies 100 are assembled through the first convex plate 110 and the second convex plate 130, and the positions of the plurality of through holes 140 correspond to those of the plurality of mounting holes 120.

[0033] As Figure 1As shown, the number of the multiple threaded sleeves 200 is equal to that of the multiple mounting holes 120, and the multiple threaded sleeves 200 are fixedly connected to the multiple mounting holes 120 in a one-to-one correspondence. The threaded sleeve 200, the mounting hole 120, and the first convex plate 110 form an integral body.

[0034] As Figure 1 shown, the number of the multiple bolts 300 is equal to that of the multiple threaded sleeves 200, and the multiple bolts 300 pass through the through holes 140 in a one-to-one correspondence and are in fit connection with the threaded sleeves 200, realizing the threaded connection between the bolts 300 and the threaded sleeves 200, thereby realizing the connection between the first convex plate 110 and the second convex plate 130, that is, realizing the connection between two adjacent fireproof board bodies 100.

[0035] When connecting two adjacent fireproof board bodies 100, the first convex plate 110 and the second convex plate 130 are made opposite to each other so that the through hole 140 corresponds to the threaded sleeve 200, and then the bolt 300 is passed through the through hole 140 and screwed into the threaded sleeve 200, realizing the threaded connection between the bolt 300 and the threaded sleeve 200, thereby realizing the fixed connection between the first convex plate 110 and the second convex plate 130.

[0036] Compared with the prior art, the assembled splicing structure of the fireproof board realizes the fixed connection between the first convex plate 110 and the second convex plate 130 through the threaded connection between the bolt 300 and the threaded sleeve 200. The threaded sleeve 200 is fixed on the first convex plate 110, so there is no risk of falling. Moreover, the construction workers only need to screw the bolt 300 from one side of the second convex plate 130, and there is no need to arrange personnel to operate on both sides of the fireproof board body 100, thus ensuring the installation efficiency.

[0037] In some embodiments, as Figure 2 and Figure 4 shown, the mounting hole 120 is provided with a plurality of grooves 121 evenly distributed along its circumferential direction, and the outer wall of the threaded sleeve 200 is provided with a plurality of ribs 210 evenly distributed along its circumferential direction. The number of the multiple ribs 210 is equal to that of the multiple grooves 121 and they are arranged in a one-to-one correspondence. The rib 210 and the groove 121 can be snap-connected to increase the circumferential acting force between the threaded sleeve 200 and the mounting hole 120, avoiding the possible rotation of the threaded sleeve 200 when screwing in the bolt 300 and ensuring the installation firmness of the threaded sleeve 200.

[0038] In some embodiments, glue is coated between the threaded sleeve 200 and the mounting hole 120 to make the connection between the threaded sleeve 200 and the mounting hole 120 more firm.

[0039] In some embodiments, as Figure 2As shown, a receiving groove 141 is provided at one end of the through hole 140 away from the threaded sleeve 200. When the bolt 300 is screwed into the threaded sleeve 200, the tail of the bolt 300 can enter the receiving groove 141, so that the tail of the bolt 300 does not protrude beyond the second convex plate 130.

[0040] In some embodiments, as Figure 2 and Figure 3 shown, the first convex plate 110 is provided with a guiding rib 150, and the second convex plate 130 is provided with a guiding groove 160. Both the guiding rib 150 and the guiding groove 160 extend along the length direction of the fireproof board body 100. When two adjacent fireproof board bodies 100 are connected, the connection positioning of the two adjacent fireproof board bodies 100 can be realized through the cooperation of the guiding groove 160 and the guiding rib 150. When two adjacent fireproof board bodies 100 are connected, first make the guiding rib 150 and the guiding groove 160 cooperate, then push the fireproof board body 100 to make the through hole 140 correspond to the threaded sleeve 200, and then screw the bolt 300 into the threaded sleeve 200 to realize the connection of two adjacent fireproof board bodies 100.

[0041] In some embodiments, as Figure 2 shown, the cross-section of the guiding rib 150 is trapezoidal. Correspondingly, the shape of the guiding groove 160 is also trapezoidal, and the dimension of the guiding rib 150 along the direction away from the first convex plate 110 is increasing (which can be understood as an inverted trapezoid). In this way, when the guiding rib 150 and the guiding groove 160 cooperate, it can also play a role in clamping the first convex plate 110 and the second convex plate 130 in the thickness direction, avoiding the problem that the first convex plate 110 and the second convex plate 130 may open, and also making it easier for the bolt 300 to be screwed with the threaded sleeve 200.

[0042] In some embodiments, the thicknesses of both the first convex plate 110 and the second convex plate 130 are half of the thickness of the fireproof board body 100. When two adjacent fireproof board bodies 100 are connected, the first convex plate 110 and the second convex plate 130 just form the thickness of a fireproof board body 100, and the structure is more reasonable.

[0043] In some embodiments, the wall thickness of the threaded sleeve 200 is at least 5 mm, so that the threaded sleeve 200 has sufficient structural strength to withstand the screwing-in of the bolt 300. In implementation, the wall thickness of the threaded sleeve 200 can be appropriately adjusted according to the specification of the actually selected bolt 300, as long as the strength requirement can be met.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
