Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, specifically to a prefabricated building structural panel component and a building node with oblique bolts. Background Technology

[0002] Prefabricated buildings, with their advantages of standardization, factory production, and assembly, have become a core direction for the green transformation of the construction industry. They effectively solve many pain points of traditional cast-in-place buildings by prefabricating beams, columns, and other components in factories and then assembling them on site.

[0003] Traditional prefabricated building construction typically involves first installing precast beams and columns to build a framework, then laying floor slabs and installing wall panels. The connection between the floor slabs and wall panels and the beams and columns is usually achieved through on-site welding of studs and binding of reinforcing bars.

[0004] Existing prefabricated buildings have the following drawbacks:

[0005] First, it requires prefabricated beams and columns to build the framework before laying floor slabs and installing wall panels, which results in low assembly efficiency.

[0006] Secondly, gaps exist at the contact surfaces of bolted components, making subsequent sealing treatment prone to incomplete sealing. The shrinkage of the secondary grouting concrete and the deformation of the building can easily cause the sealing layer to fail, leading to leakage and affecting the durability of the structure. Summary of the Invention

The polygonal component forms corners on both sides of the structural panel body and on the side away from the side end of the structural panel body. Connecting edges are formed between the corners on both sides of the structural panel body and the side end of the structural panel body, and between the corners on both sides and the corner away from the side of the structural panel body. Each corner is provided with a recess. When two structural panel components are spliced, any corner of the polygonal component of one structural panel component abuts against any corner of the polygonal component of another structural panel component, and the two sides of the two abutting corners respectively form a V-shaped angle for installing a connector. A cavity for installing a sealing strip is formed between the recesses of the two abutting corners.

[0020] Furthermore, the structural plate component is provided in four parts, with three corners of one structural plate component abutting against the corners of the other three structural plate components respectively. The middle structural plate component forms a U-shaped groove between itself and two structural plate components connected to one side and the other side, and between itself and two structural plate components connected to the other side.

Detailed Implementation

[0049] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0050] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

[0051] like Figure 1As shown, this embodiment of the invention provides a prefabricated building structural panel component 100, including a structural panel body 110 and a polygonal component 120 fixedly disposed on the side end of the structural panel body 110. The polygonal component 120 forms corners 121 on both sides of the structural panel body 110 and on the side away from the side end of the structural panel body 110. The corners 121 on both sides of the polygonal component 120 are located between the corners 121 and the side end of the structural panel body 110, and the corners 121 on both sides are located between the corners 121 and the side end of the structural panel body 110, and the corners 121 on both sides are located between the corners 121 and the side away from the side of the structural panel body 110. Connecting edges 122 are formed between corners 121, and a recess 123 is provided at each corner 121. When two structural plate components 100 are spliced, any corner 121 of the polygonal component 120 of one structural plate component 100 abuts against any corner 121 of the polygonal component 120 of the other structural plate component 100, and V-shaped angles 200 for installing connectors are formed on both sides of the two abutting corners 121, and a cavity for installing sealing strip 500 is formed between the recesses 123 of the two abutting corners 121.

[0052] The structural panel component 100 of the present invention adopts a structure in which polygonal components 120 are set on the side end of the structural panel body 110. It can be prefabricated in the factory as a whole. During assembly, the polygonal components 120 of each structural panel component 100 are connected by bolts 420 to form a building whole. The polygonal components 120 can be directly used as beams and columns of the building. This eliminates the need to install prefabricated beams and columns to build a frame, reduces the difficulty of assembly, improves the efficiency of assembly, and meets the strength requirements of the building.

[0053] Each structural panel component 100 is connected by abutting the corners 121 of the polygonal component 120. After the connection, the two corners 121 that abut each other can form a V-shaped angle 200. When fixing, bolts 420 can be driven obliquely within the V-shaped angle 200 to fix the connecting parts. The tightening angle is open and easy to use with a general electric wrench. The operation is convenient and the bolts 420 do not protrude from the wall after tightening, resulting in an aesthetically pleasing appearance.

[0054] Each structural panel component 100 is joined together by abutting the corners 121 of the polygonal component 120. At the same time, a recess 123 is provided at each corner 121 of the polygonal component 120 of the structural panel component 100. When two structural panel components 100 are spliced, a sealing strip 500 can be installed between the recesses 123 of the two abutting corners 121. This can improve the sealing performance of the splicing of the two structural panel components 100 and improve the water-stopping effect of the assembly.

[0055] In some embodiments, the polygonal member 120 adopts a hollow tubular structure filled with rubber, which can enhance the seismic and energy absorption effect.

[0056] like Figures 2-15As shown, this embodiment of the invention provides a building node with oblique bolting, including at least two structural plate components 100. The polygonal components 120 of each structural plate component 100 are connected in pairs. In the two connected polygonal components 120, one corner 121 of one polygonal component 120 abuts against one corner 121 of the other polygonal component 120. The connecting edges 122 on each side of the two abutting corners 121 are fixedly connected by connectors. A sealing strip 500 is provided between the recesses 123 of the two abutting corners 121.

[0057] In some embodiments, such as Figure 8 and Figure 9 As shown, there are two structural plate components 100, one side corner 121 of one structural plate component 100 abuts against the other side corner 121 of the other structural plate component 100, and the two sides of the abutting side corner 121 respectively form a V-shaped included angle 200.

[0058] The connector includes a V-shaped angle plate 410. Each V-shaped angle 200 is provided with a V-shaped angle plate 410. The two side plates of each V-shaped angle plate 410 are fixed to the connecting edge 122 on both sides of the corresponding V-shaped angle 200 by bolts 420.

[0059] The function of the V-shaped angle plate 410 is to fix two adjacent structural plate components 100 together. During connection, bolts 420 can be screwed in from the oblique direction to fix the two side plates of the V-shaped angle plate 410 to the structural plate components 100 respectively.

[0060] Optionally, in order to improve the strength of the V-shaped angle plate 410, stiffening plates are provided at both ends of the V-shaped angle plate 410.

[0061] Optionally, refer to Figure 2 To facilitate the screwing in of the bolt 420, the two side plates of the V-shaped angle plate 410 are provided with through holes for the bolt 420 to pass through. The outer end of the through hole is provided with an inner conical surface, and the inner side of the end cap of the bolt 420 is provided with an outer conical surface that matches the inner conical surface of the outer end of the through hole. This allows the bolt 420 to be more firmly joined to the side plate of the V-shaped angle plate 410.

[0062] Optionally, the two sides of the main body of the structural plate 110 are roughly flush with the corners 121 on both sides of the polygonal component 120, so that there are no protruding parts on both sides after the two structural plate components 100 are assembled. The two sides of the side end of the main body of the structural plate 110 are provided with inclined surfaces to leave enough space for the installation of the V-shaped angle plate 410.

[0063] Reference Figure 8 The corners 121 of the two structural plate components 100 abut against each other, and the two structural plate components 100 can be assembled into a straight structure.

[0064] Reference Figure 9 The corner 121 of one side of a structural panel component 100 abuts against the corner 121 of one side of another structural panel component 100, and the two structural panel components 100 can be assembled into an L-shaped structure.

[0065] In some embodiments, refer to Figure 10 The structural panel component 100 is provided in three parts. The corners 121 on both sides of one of the structural panel components 100 abut against the corners 121 on the sides of the other two structural panel components 100 respectively, and the two sides of each pair of abutting corners 121 form a V-shaped angle 200.

[0066] The connector includes a V-shaped angle plate 410. Each V-shaped angle 200 is provided with a V-shaped angle plate 410. The two side plates of each V-shaped angle plate 410 are fixed to the connecting edge 122 on both sides of the corresponding V-shaped angle 200 by bolts 420.

[0067] Using the above method, the three structural panel components 100 can be assembled into a T-shaped structure.

[0068] In some embodiments, refer to Figure 11 The structural panel component 100 is provided in three parts. One side corner 121 and the side corner 121 of one structural panel component 100 respectively abut against the side corners 121 of the other two structural panel components 100. The polygonal components 120 of the three structural panel components 100 form U-shaped grooves 300 on one side of the two pairs of abutting corners 121, and V-shaped angles 200 are formed on the other side of each pair of abutting corners 121.

[0069] The connectors include a V-shaped angle plate 410 and a three-sided connector 430.

[0070] The two side plates of each V-shaped angle plate 410 are fixed to the connecting edge 122 on both sides of the corresponding V-shaped angle 200 by bolts 420.

[0071] The U-shaped groove 300 is provided with a three-sided connector 430, which is fixedly connected to the polygonal components 120 of the three structural plate components 100 respectively.

[0072] Using the above method, the three structural panel components 100 can be assembled into another T-shaped structure.

[0073] In some embodiments, refer to Figure 12The structural panel component 100 is provided with four components. The three corners 121 of one structural panel component 100 abut against the corners 121 of the other three structural panel components 100 respectively. The middle structural panel component 100 and the two structural panel components 100 connected to one side and the other side respectively form U-shaped grooves 300. The two pairs of abutting corners 121 on both sides of the middle structural panel component 100 form a V-shaped angle 200 with the side opposite to the U-shaped groove 300.

[0074] The connectors include a V-shaped angle plate 410 and a three-sided connector 430.

[0075] The two side plates of each V-shaped angle plate 410 are fixed to the connecting edge 122 on both sides of the corresponding V-shaped angle 200 by bolts 420.

[0076] The U-shaped groove 300 is provided with a three-sided connector 430, which is fixedly connected to three structural plate components 100 respectively.

[0077] Using the above method, the four structural panel components 100 can be assembled into a cross-shaped structure.

[0078] The function of the three-sided connector 430 is to fix three adjacent structural plate components 100 together.

[0079] In some embodiments, refer to Figures 13-15 The three-sided connector 430 includes a U-shaped connector 433. The three side plates of the U-shaped connector 433 are respectively fixedly connected to the connecting edges 122 of the three structural plate members 100 around the U-shaped groove 300 by bolts 420.

[0080] When the three adjacent structural plate components 100 are connected together using the above-mentioned three-sided connector 430, the U-shaped connector 433 can be inserted into the U-shaped groove 300 formed by the three structural plate components 100, and then bolts 420 can be screwed into the three side plates of the U-shaped connector 433 to fix the three corresponding connecting edges 122 of the three structural plate components 100. The structure is relatively simple, but the connection strength is not very high, and the operation is relatively troublesome, especially in a narrow space, it is relatively difficult to screw in the screws on both sides of the U-shaped connector 433.

[0081] In some embodiments, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 11 as well as Figure 12 The three-sided connector 430 includes two cards 431 and a locking block 432.

[0082] The recessed portion 123 of each corner 121 of the polygonal component 120 of the structural panel component 100 adopts a narrowed locking groove. Two cards 431 are respectively provided on both sides of the U-shaped clamping groove 300. One end of each card 431 is provided with a lock head 4311 that is locked in a locking groove on the outside of the U-shaped clamping groove 300. The other end of the card 431 extends into the U-shaped clamping groove 300 and is provided with a trapezoidal card block 4312 that is wider at the inner end and narrower at the outer end.

[0083] The locking block 432 is located between the cards 431 on both sides of the U-shaped clamping groove 300. The two sides of the locking block 432 are provided with trapezoidal slots 4321 that are wider at the inner end and narrower at the outer end. The middle part of the locking block 432 is fixed to the connecting edge 122 of the structural plate component 100 at the bottom of the U-shaped clamping groove 300 by bolts 420, and the trapezoidal card blocks 4312 on each card 431 are respectively inserted into the trapezoidal slots 4321 on the corresponding side of the locking block 432.

[0084] When the three adjacent structural plate components 100 are connected together using the three-sided connector 430, the lock heads 4311 on the two cards 431 can be respectively inserted into the lock grooves on both sides of the U-shaped clamping groove 300. Then, the trapezoidal slots 4321 on both sides of the lock block 432 are locked onto the trapezoidal blocks 4312 on the two cards 431. Finally, the bolts 420 are screwed in obliquely to fix the connecting edge 122 of the lock block 432 and the structural plate component 100 at the bottom of the U-shaped clamping groove 300. In this way, the trapezoidal blocks 4312 on the two cards 431 can be locked in the U-shaped clamping groove 300 through the trapezoidal slots 4321 on both sides of the lock block 432. The structural plate components 100 on both sides of the U-shaped clamping groove 300 can be tightened by the cards 431 on both sides, so as to realize the fixed connection of the three adjacent structural plate components 100. The above-mentioned fixing method has high connection strength and is suitable for assembling high-strength structural plate components 100. Moreover, it only requires one bolt 420 to be screwed in at an angle during connection, which can improve connection efficiency and reduce assembly difficulty.

[0085] In summary, this embodiment uses structural panel components 100 with polygonal members 120 at the ends of the main structural panel 110 to assemble common prefabricated building structures such as straight lines, L-shaped structures, T-shaped structures, and cross-shaped structures. The structural panel components 100 can be mass-produced in factories, and beams and columns are included in the prefabricated structural panel components 100, achieving equivalent strength through combined connections. Through integrated design, prefabricated beams and columns do not need to be installed first to build a framework during assembly, reducing assembly difficulty, improving assembly efficiency, and simultaneously meeting the building's strength requirements.

[0086] The above design is suitable for large-scale production, and on-site installation can be quickly achieved by screwing in screws. It is easy to cooperate with workers to assemble, realizing the transformation of traditional construction workers to prefabricated construction workers.

[0087] During assembly in this embodiment, the structural panel components 100 are joined together by the corners 121 of the polygonal component 120. Each corner 121 of the polygonal component 120 is provided with a recess 123, so that a sealing strip 500 can be installed between the recesses 123 of each pair of corners 121 that are joined together. This can improve the sealing performance of the joint of each structural panel component 100 and improve the water-stopping effect of the assembly.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
