Description

Technical Field

[0001] The present invention relates to a multi-functional connector for prefabricated wooden structure buildings and a method for building wooden houses, belonging to the technical field of prefabricated wooden structure buildings. Background Art

[0002] A wooden structure building is a building that uses wood to form load-bearing members. Its load-bearing structure is solely composed of wood or mainly composed of wood, and is connected and fixed by mortise and tenon methods or metal connectors. Traditional wooden structures usually use mortise and tenon connections. The method is to cut holes and tenons at the joints of columns or beams, and the tenons are tightly inserted into the holes to complete the connection. The main disadvantages of mortise and tenon connections are as follows: First, the local shear and torsional strength are weak. To achieve the required strength, only the overall material can be increased in size, but this will increase the consumption of materials and occupy more space. Second, the processing technology is complex and requires special mortise and tenon processing equipment. Third, the assembly relies on artificial impact force and is not suitable for repeated disassembly and assembly.

[0003] There are many rigid connection methods for modern wooden structures, such as external toothed plate connections, steel plate connections, hanging buckle connections, steel nail connections, self-tapping screw connections, and the SE construction method connection in Japan. These connection methods still have some disadvantages: it is difficult to achieve rapid disassembly and assembly; it is difficult to achieve the segmented production of prefabricated wooden structure components; there is no load-bearing lifting point for a single component; the production process is complex and the precision requirements are high; it cannot be repeatedly disassembled and assembled and is not suitable for prefabricated wooden structure buildings.

[0004] For example, in the Chinese patent document with the publication number CN204001215U, there is no load-bearing lifting point for a single component on the first connecting rod and the second connecting rod of the wooden reinforced connecting rod disclosed therein. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a multi-functional connector for prefabricated wooden structure buildings and a method for building wooden houses.

[0006] The present invention is achieved through the following technical solutions:

The bottom plate of the beam connector is provided with a row of bolt holes E, and the number of bolt holes E is 3. And nuts A are welded at the positions corresponding to the bolt holes E on the inner side of the beam connector.

[0015] B. Assembling walls: Assemble two assembled columns and two assembled beams together through fasteners to form a square frame, and complete the installation of the inner enclosure structure during the assembly process of the square frame to obtain assembled walls;

[0016] C. Assembling the wooden house: Connect the assembled columns and assembled beams in several assembled walls through fasteners, and then connect the lower ends of the assembled columns to the foundation through fasteners to obtain an assembled wooden house.

[0017] In the step A, the end of the column is provided with a cross groove whose shape and size match those of the cross, and bolt holes F are provided at positions corresponding to the bolt holes C on the cross. The ends of the beam are provided with two slots arranged side by side whose shapes and sizes match those of the side plates of the beam connector, and two rows of holes are provided at positions corresponding to the bolt holes D on the beam connector. Each row of holes includes a pin hole and two bolt holes G, and the pin hole is located between the two bolt holes G. An avoidance hole is provided at the position of the end of the beam corresponding to the nut A on the beam connector.

[0018] In step A, the crosses on the two-column connectors are respectively inserted into the cross grooves at both ends of the columns, and the openings of the square boxes in the two-column connectors face the same direction. A flat washer is sleeved on the bolt, and one end of the bolt passes through bolt hole F and bolt hole C. Then, the flat washer, spring washer, and nut are sleeved on the bolt and the nut is tightened to obtain an assembled column. The side plates on the two-beam connectors are correspondingly inserted into the card slots at both ends of the beam. One end of the pin shaft passes through the pin hole and bolt hole D, and circlips are installed at both ends of the pin shaft for positioning. The mutual positioning of the beam connector and the beam is completed. A flat washer is sleeved on the bolt, and one end of the bolt passes through bolt hole G and bolt hole D.

Detailed implementation manners

[0046] The technical solutions of the present invention will be further described below, but the scope of protection is not limited thereto.

[0047] As Figures 1 to 19 shown, a multifunctional connector for an assembled wooden structure building according to the present invention includes a column connector 1 and a beam connector 2. The column connector 1 includes a square box 11 and a cross 15 fixedly welded to the square box 11. The beam connector 2 is U-shaped and can be connected to the side surface of the square box 11 through fasteners.

[0048] The square box 11 includes a square steel pipe. One end of the square steel pipe is fixedly welded with a sealing steel plate 12. A plurality of bolt holes A 13 are processed at the bottom of the square box 11, and a plurality of bolt holes B 14 are processed on each side surface of the square box 11. In use, the square steel pipe is cut and processed from a standard square pipe or rectangular pipe with a size of 120×120×6 or more. The thickness of the sealing steel plate 12 is equal to the wall thickness of the square steel pipe. One end of the square box 11 is open, leaving sufficient space for installation operations, facilitating the connection and disassembly of the column connector 1 and the beam connector 2.

[0049] Four bolt holes A 13 are processed at the bottom of the square box 11. The central connection lines of the four bolt holes A 13 form a rectangle. Three bolt holes B 14 are processed on each side surface of the square box 11, and the three bolt holes B 14 are arranged in a row. The hole distances between the bolt holes B 14 are equal.

[0050] One end of the cross 15 is welded to the top of the square box 11. The cross 15 is fabricated by assembling and welding multiple steel plates A, and several bolt holes C16 are provided on each steel plate A. During use, the cross 15 is fabricated by assembling and welding Q235 steel plates A with a thickness equal to the wall thickness of the square steel tube.

[0051] Three bolt holes C16 are machined on each of the steel plates A. The three bolt holes C16 are arranged in a column. The bolt holes C16 on the same steel plate A or two coplanar steel plates A are arranged in one-to-one correspondence at the same elevation, and the bolt holes C16 on two mutually perpendicular steel plates A are arranged in a staggered manner. The hole pitch between the bolt holes C16 is equal. The bolt holes C16 on two mutually perpendicular steel plates A are arranged in a staggered manner to prevent the bolts passing through the bolt holes C16 from interfering with each other.

[0052] The beam connector 2 is fabricated by bending a steel plate B or by assembling and welding multiple steel plates B. Two rows of bolt holes D23 are machined on both side plates of the beam connector 2, with 3 bolt holes D23 in each row. One column of bolt holes E24 is machined on the bottom plate of the beam connector 2, with 3 bolt holes E24. And nuts A22 are welded at positions corresponding to the bolt holes E24 on the inner side of the beam connector 2. During use, the beam connector 2 is made of Q235 steel plate B, and the hole pitch between the bolt holes E24 is equal to the hole pitch between the bolt holes B14.

[0053] A method for building a wooden house with a multi-functional connector for an assembled wooden structure building includes the following main steps:

[0054] A. Assembling columns and beams: Install column connectors 1 at the ends of each column 3 through fasteners, and install beam connectors 2 at the ends of each beam 4 through fasteners and pins 5 to obtain assembled columns and assembled beams;

[0055] B. Assembling walls: Assemble two assembled columns and two assembled beams together through fasteners to form a square frame, and complete the installation of the inner enclosure structure during the assembly process of the square frame to obtain an assembled wall;

[0056] C. Assembling the wooden house: Connect the assembled columns and assembled beams in several assembled walls through fasteners, and then connect the lower ends of the assembled columns to the foundation 7 through fasteners to obtain an assembled wooden house.

[0057] In the said step A, a cross groove 30 with a shape and size matching that of the cross 15 is machined at the end of the column 3, and a bolt hole F is machined at a position corresponding to the bolt hole C16 on the cross 15. At the end of the beam 4, two card slots 40 with a shape and size matching the two side plates of the beam connector 2 are machined side by side, and two rows of holes are machined at a position corresponding to the bolt hole D23 on the beam connector 2. Each row of holes includes a pin hole and two bolt holes G42, and the pin hole is located between the two bolt holes G42. At the end of the beam 4, an avoidance hole 41 is machined at a position corresponding to the nut A22 on the beam connector 2. During use, the avoidance hole 41 is used to accommodate the nut A22, enabling the bottom plate of the beam connector 2 to closely adhere to the end face of the beam 4, so that the beam connector 2 can be tightly connected to the beam 4, which helps to improve the shear and torsion resistance strength of the beam.

[0058] In the said step A, the crosses 15 on the two column connectors 1 are respectively inserted into the cross grooves 30 at both ends of the column 3, and the openings of the square boxes 11 in the two column connectors 1 face the same direction. A flat washer is sleeved on the bolt, one end of the bolt passes through the bolt hole F and the bolt hole C16, and then the flat washer, spring washer and nut are sleeved on the bolt and the nut is tightened to obtain an assembled column. The side plates on the two beam connectors 2 are correspondingly inserted into the card slots 40 at both ends of the beam 4, one end of the pin shaft 5 passes through the pin hole and the bolt hole D23, and snap rings are installed at both ends of the pin shaft 5 for positioning to complete the mutual positioning of the beam connector 2 and the beam 4. A flat washer is sleeved on the bolt, one end of the bolt passes through the bolt hole G42 and the bolt hole D23, and then the flat washer, spring washer and nut are sleeved on the bolt and the nut is tightened to obtain an assembled beam.

[0059] In the said step B, lifting rings 6 are installed at both ends of the top of the assembled wall. One end of the stud on the lifting ring 6 passes through the bolt hole A13 on the square box 11 and is locked and fixed with a nut. In the said step B, one end of the bolt with a flat washer sleeved passes through the bolt hole B14 on the square box 11 and the bolt hole E24 on the beam connector 2, and then is screwed into the nut A22 and tightened to complete the connection work between the assembled column and the assembled beam. In the said step C, a stud is embedded at a position on the foundation 7 corresponding to the bolt hole A13 on the square box 11. During use, lifting rings 6 can be installed on the column connectors 1 at both ends of the column 3, the beam connectors 2 at both ends of the beam 4, and the connectors at the top of the assembled wall to facilitate the hoisting of the column 3, beam 4, assembled wall and assembled wooden house, etc. After one end of the stud on the foundation 7 passes through the bolt hole A13 on the lower square box 11 of the assembled column, the flat washer, spring washer and nut are successively sleeved on the embedded stud, and then the nut is tightened to complete the connection work between the assembled wooden house and the foundation 7.

[0060] Specifically, the outer surfaces of the column connector 1 and the beam connector 2 are both treated with galvanized anti-rust, which helps to extend the service life of the connectors.

[0062] 1. After using the column connector 1 and the beam connector 2, the connection between the beam 4 and the column 3, between the column 3 and the column 3, between the assembled walls, and between the assembled wall and the foundation 7 can be realized, and the practicability is strong.

[0063] 2. Fasteners are used for connecting between the column connector 1 and the column connector 1, between the column connector 1 and the beam connector 2, between the column connector 1 and the foundation 7, between the column connector 1 and the column 3, and between the beam connector 2 and the beam 4, which can achieve quick disassembly and assembly, and each component can be disassembled, assembled and reused repeatedly.

[0064] 3. The column connector 1, the beam connector 2, the column 3 and the beam 4 can be separately manufactured simultaneously, and can be pre-assembled to obtain assembled columns, assembled beams, assembled walls, etc., which helps to simplify the production process of components, reduce the precision requirements, improve the production efficiency, and helps to shorten the production cycle of wooden structure buildings.

[0065] 4. The column connector 1 and the beam connector 2 are steel components, which can improve the shear and torsion resistance strength at the beam-column connection, and at the same time make the connection point more tightly and firmly, suitable for 90° connection and lapping of columns and beams, etc., and lifting rings 6 can be installed on the column connector 1 and the beam connector 2 to form lifting stress points to ensure that the assembled wall is not damaged during assembly, transportation and installation.
