DETAILED DESCRIPTION

[0035] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0036] At present, when wooden components are spliced, a mortise and tenon structure is usually used. The mortise and tenon is a connection method that combines concave and convex parts on two components. The convex part is called the tenon, and the concave part is called the mortise. However, the mortise and tenon structure greatly weakens the cross-section of the wooden component, which leads to poor shear, tensile and bending resistance at the splicing of the wooden components. In order to solve the above problems, the embodiment of the utility model provides a wooden column splicing structure.

[0037] Reference Figures 1 to 5 The utility model embodiment discloses a wood column splicing structure, comprising: an upper wood column 1, including a bottom splicing section 12; a lower wood column 2, including a top splicing section 22, the bottom splicing section 12 is in contact with the top splicing section 22; a steel connection frame 3, connected to the outer sides of the bottom splicing section 12 and the top splicing section 22 by a plurality of steel screws 4, and the inner wall 32 of the steel connection frame 3 is tightly attached to the side walls of the bottom splicing section 12 and the side walls of the top splicing section 22, the end of each steel screw 4 is welded to the steel connection frame 3, and the end face of each steel screw 4 is flush with the outer wall 33 of the steel connection frame 3.

[0038] Specifically, several of the steel screws 4 penetrate the steel connection frame 3 and the bottom splicing section 12, and the other several steel screws 4 penetrate the steel connection frame 3 and the top splicing section 22. The steel connection frame 3 is provided with through holes for matching with the steel screws 4, and the ends of the steel screws 4 are welded in the through holes on the steel connection frame 3. The welding method of the ends of the steel screws 4 and the through holes on the steel connection frame 3 can be plug welding. The material of the steel connection frame 3 can be Q235B steel. The steel screws 4 can be high-strength screws or screws made of Q235B material. The number and diameter of the steel screws 4 are determined based on the tension, shear force, and bending moment at the joint of the upper wooden column 1 and the lower wooden column 2.

[0039] In the embodiment of the utility model, the splicing between the upper wooden column 1 and the lower wooden column 2 is achieved by a steel connection frame 3 and a plurality of steel screws 4. Compared with the splicing using a mortise and tenon structure, there is no need to open a mortise groove on the upper wooden column 1 or the lower wooden column 2, thereby reducing the weakening of the cross section of the upper wooden column 1 or the lower wooden column 2, and improving the tensile, bending and shearing resistance of the splicing between the upper wooden column 1 and the lower wooden column 2. In addition, the end of the steel screw 4 is connected to the steel connection frame 3 by welding, and the connection is reliable; the steel connection frame 3 also plays a reinforcing role, improving the strength of the splicing between the upper wooden column 1 and the lower wooden column 2. In addition, the end face of each steel screw 4 is flush with the outer wall 33 of the steel connection frame 3, so that the appearance of the splicing between the upper wooden column 1 and the lower wooden column 2 is smooth and beautiful.

[0040] In addition, the mortise and tenon structure needs to be precisely processed and spliced, which has high requirements for carpentry, and the production process is relatively complicated, time-consuming and labor-intensive. In the embodiment of the utility model, the upper wooden column 1, the lower wooden column 2 and the steel connection frame 3 can be pre-produced and then assembled on site with multiple steel screws 4, which is convenient to assemble, fast in construction speed, and highly industrialized, which can greatly reduce the labor intensity and workload of workers.

[0041] In addition, in the prior art, when the wood component is connected to the steel plate, there is a gap between the wood component and the steel plate, and the force is transmitted only through the screw rod, and the bending, tensile and shearing resistance are slightly poor. In the embodiment of the utility model, the inner wall 32 of the steel connection frame 3 is tightly attached to the side wall of the bottom splicing section 12 and the side wall of the top splicing section 22, that is, there is no gap between the steel connection frame 3 and the upper wooden column 1 and the lower wooden column 2. In addition to transmitting force through the steel screw rod 4, the force can also be transmitted through the friction between the steel connection frame 3 and the upper wooden column 1 and the lower wooden column 2, thereby improving the bending, tensile and shearing resistance.

[0042] The tension and bending force transmission path of the upper wooden column 1 is: upper wooden column 1-steel screw 4-bending plate 31-lower wooden column 2, wherein the friction force between the upper wooden column 1 and the two bending plates 31 is used as a safety reserve. The shear force transmission path of the upper wooden column 1 is: upper wooden column 1-bending plate 31-lower wooden column 2.

[0044] Specifically, after the steel screw 4 is processed, the length of the steel screw 4 is relatively long. When the steel screw 4 is installed, part of the steel screw 4 protrudes from the steel connecting frame 3. After the steel screw 4 and the steel connecting frame 3 are welded, the part of the steel screw 4 protruding from the steel connecting frame 3 is cut off by a cutting tool so that the end faces of the steel screw 4 are flush with the outer wall 33 of the steel connecting frame 3.

[0045] The processed steel screw 4 includes a main rod portion, which has a first end and a second end relatively arranged, and the first end and the second end are both used for welding with the steel connecting frame 3. The first end of the main rod portion is connected to a protruding section, and the second end of the main rod portion is not connected to the protruding section, that is, after the steel screw 4 is inserted into the steel connecting frame 3 and before welding, the second end of the steel screw 4 is flush with the outer wall 33 of the steel connecting frame 3, and the protruding section of the steel screw 4 protrudes from the steel connecting frame 3.

[0046] The installation process of the steel screw 4 is as follows: after the steel screw 4 is inserted into the steel connection frame 3, the upper wooden column 1 or the lower wooden column 2, the second end of the main rod is first welded to the steel connection frame 3; then, a temporary assembly component 8 is installed on the protruding section, and the nut 83 in the temporary assembly component 8 is tightened to make the steel connection frame 3 close to the upper wooden column 1 and the lower wooden column 2; then, the first end of the main rod is welded to the steel connection frame 3; then, the temporary assembly component 8 is removed, and the protruding section is cut off, leaving only the main rod. It should be noted that each steel screw 4 needs to be installed in this way. The temporary assembly component 8 can be reused.

[0047] In the embodiment of the utility model, by setting the temporary assembly component 8, the steel connection frame 3 can be tightly attached to the upper wooden column 1 and the lower wooden column 2 before the welding of the steel screw 4 and the steel connection frame 3 is completed, so as to ensure that there is no gap between the steel connection frame 3 and the upper wooden column 1 and the lower wooden column 2 after the welding of the steel screw 4 and the steel connection frame 3 is completed.

[0048] Reference Figures 6 to 8 The temporary assembly component 8 also includes a support member 81, which is located between the steel connection frame 3 and the nut 83; the support member 81 includes a main plate 811 and a plurality of legs 812 connected to the main plate 811, and the main plate 811 is provided with a through hole 8111 for the protruding section to pass through, and the plurality of legs 812 are distributed at intervals, and the plurality of legs 812 are used to press against the steel connection frame 3.

[0049] Specifically, the temporary assembly component 8 further includes a steel gasket 82, which is located between the support member 81 and the nut 83. The cross-section of the main plate 811 is circular, and the number of the legs 812 can be three, and the three legs 812 are evenly distributed along the circumference of the main plate 811. The cross-section of the through hole 8111 is circular, and the difference between the diameter of the through hole 8111 and the diameter of the steel screw 4 is 2 mm.

[0050] When installing the temporary assembly component 8 on the protruding section, first install the support member 81, then install the steel gasket 82, and finally install the nut 83. When removing the temporary assembly component 8, first unscrew the nut 83, and then remove the steel gasket 82 and the support member 81.

[0051] In the embodiment of the utility model, by providing a plurality of spaced-apart legs 812 in the support member 81 , after the nut 83 is tightened, the first end of the main rod portion can be welded to the steel connection frame 3 through the space between two adjacent legs 812 .

[0052] The steel connection frame 3 includes two welded bending plates 31, the cross section of the bending plate 31 is L-shaped, and the cross section of the steel connection frame 3 is square. The cross section of the steel connection frame 3 is preferably rectangular.

The thickness of the steel connection frame 3 is greater than the thickness of the steel pad 5, and is less than or equal to 3 times the thickness of the steel pad 5. The material of the steel pad 5 is consistent with the material of the steel connection frame 3.

[0055] After the multiple steel screws 4 are installed, the two bent plates 31 are welded. When the two bent plates 31 are welded, the heat during the welding process will be transferred to the steel pad 5, which prevents the heat during the welding process from being directly transferred to the upper wooden column 1 and the lower wooden column 2, causing the upper wooden column 1 and the lower wooden column 2 to be burned.

[0056] Reference Figure 1 , Figure 2 and Figure 4 The bottom joint section 12 is provided with two first mounting grooves, the top joint section 22 is provided with two second mounting grooves 221 corresponding to the two first mounting grooves, and each steel pad 5 is bonded in the first mounting groove and the second mounting groove 221 .

There is a height difference between the first steel screw 41 and the second steel screw 42 on the bottom splicing section 12 to avoid interference between the first steel screw 41 and the second steel screw 42. There is also a height difference between the first steel screw 41 and the second steel screw 42 on the top splicing section 22.

[0061] The steel connection frame 3 is provided with a first through hole 35 for the first steel screw 41 to pass through and a second through hole 36 for the second steel screw 42 to pass through. The difference between the diameter of the first through hole 35 and the diameter of the first steel screw 41 is 5 mm-6 mm, and the difference between the diameter of the second through hole 36 and the diameter of the second steel screw 42 is 5 mm-6 mm.
