Description

Technical Field

[0001] The utility model relates to the technical field of steel structure mortise and tenon structures, in particular to a multi-directional adjustable quick-connection steel structure mortise and tenon structure. Background Art

[0002] In terms of connection methods, traditional connection methods are significantly affected by the construction workers' connection skills and the construction site environment. The quality of component connections is difficult to accurately control, and construction quality is even more difficult to ensure when connecting complex steel components and working in high-altitude environments, which will inevitably affect structural safety. In addition to the above issues, the country is currently vigorously promoting prefabricated buildings and developing building industrialization to improve the environment and control energy consumption. This requires that future construction sites minimize high-energy consumption and high-environmental pollution construction operations. Traditional steel component connection methods and construction methods such as on-site welding, hole cutting, and drilling need to be improved and adjusted.

[0003] After searching, the prior art (publication number: CN107060088A) describes a "steel structure mortise and tenon connector, comprising a tenon and a mortise. The tenon is an I-shaped steel structure, and the mortise is a T-shaped steel runner. The I-shaped steel structure and the T-shaped steel runner are tightly connected to each other. Furthermore, the I-shaped steel tenon has grooves on both sides of its upper flange along the height direction. The T-shaped steel tenon has protrusions on both sides of its flange along the height direction, and the protrusions and grooves fit perfectly together. The tenon and mortise are also anchored by fixing bolts. The tenon and mortise are respectively connected to a first steel member and a second steel member before connection. The present invention also provides a connection method. The connector between the steel members of the present invention utilizes a mortise and tenon assembly joint, which not only does not weaken the original member dimensions at the connection, but also enhances the dimensions at the connection, ensuring a secure connection between the members. Furthermore, the mortise and tenon joint has a large joint surface, strong cross-sectional shear resistance, and increased safety."

[0004] Although the steel structure mortise and tenon connectors in the existing technology have achieved the effects of reliable and quick connection, there are still some shortcomings: the existing steel structure mortise and tenon connectors can only connect two steel components in one direction, while in actual applications, connections in multiple directions may be required, so there are limitations in use. Secondly, after the tenon and mortise are plugged in, they still need to be connected by bolts and nuts, which makes it more troublesome to use and the connection efficiency is low. Utility Model Content

[0005] In order to overcome the defects of the existing technology, a multi-directional adjustable quick-connect steel structure mortise and tenon structure is provided to solve the problems of connection direction limitations and low connection efficiency of existing steel structure mortise and tenon connectors.

[0006] To achieve the above-mentioned purpose, a multi-directional adjustable quick-connect steel structure mortise and tenon structure is provided, including: a first mortise and tenon piece and a second mortise and tenon piece, the outer end of the first mortise and tenon piece is welded with a first steel component, and a first pin hole is opened on the upper side of the first mortise and tenon piece, and a mortise and tenon pin is inserted into the inside of the first pin hole, and at the same time, the outer wall of the first mortise and tenon piece is respectively opened with a first mortise and tenon hole, a second mortise and tenon hole and a third mortise and tenon hole, the outer end of the second mortise and tenon piece is welded with a second steel component, and a positioning rod is welded to the inner end of the second mortise and tenon piece, and the second mortise and tenon piece is matched and connected with the first mortise and tenon hole, the second mortise and tenon hole and the third mortise and tenon hole.

[0007] Furthermore, the first mortise and tenon member is configured as a rectangular block structure, and the first pin hole is opened at the center of the rectangular block, and the first pin hole is configured as a square hole structure.

[0008] Furthermore, the first mortise and tenon hole, the second mortise and tenon hole and the third mortise and tenon hole are all configured as cross-slot hole structures, and a first positioning hole is opened inside the first mortise and tenon hole, a second positioning hole is opened inside the second mortise and tenon hole, and a third positioning hole is opened inside the third mortise and tenon hole. At the same time, the first positioning hole, the second positioning hole and the third positioning hole are all connected to the first pin hole.

[0009] Furthermore, the mortise and tenon pin is configured as a prism structure with different widths at both ends, and an elastic gap is provided at the end with the larger width.

[0010] Furthermore, one end of the mortise and tenon pin with the elastic gap is set as the outer end, and the other end is set as the inner end, and the inner end is inserted into the bottom of the first pin hole.

[0011] Furthermore, the second mortise and tenon member is configured as a cross block structure, and the outer edge of the second mortise and tenon member does not exceed the edge of the second steel member.

[0013] The beneficial effects of the present invention are:

[0014] 1. By utilizing the three mortise and tenon holes on the outside of the first mortise and tenon piece and the positioning holes on the inside of the mortise and tenon holes, the second mortise and tenon piece can be connected to the mortise and tenon holes in different directions, thereby achieving the adjustability of the connection direction between the first steel member and the second steel member, thereby improving the versatility of use;

[0015] 2. When connecting, insert the second mortise and tenon piece into the corresponding mortise and tenon hole. At this time, the positioning rod is inserted into the positioning hole, and then the narrow end of the mortise and tenon pin is inserted into the first pin hole until it is inserted into the second pin hole. At this time, the end of the mortise and tenon pin exposed outside is hammered so that its elastic gap is squeezed and reduced by the first pin hole until it completely enters the first pin hole and is flush with the first pin hole. This avoids the use of bolts and nuts and achieves a quick connection effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] Reference Figures 1 to 5 As shown, the utility model provides a multi-directional adjustable quick-connect steel structure mortise and tenon structure, including: a first mortise and tenon piece 3 and a second mortise and tenon piece 5, the outer end of the first mortise and tenon piece 3 is welded with a first steel component 1, and a first pin hole 33 is opened on the upper side of the first mortise and tenon piece 3, and a mortise and tenon pin 4 is inserted into the inside of the first pin hole 33, and the outer wall of the first mortise and tenon piece 3 is respectively opened with a first mortise and tenon hole 31, a second mortise and tenon hole 34 and a third mortise and tenon hole 36, the outer end of the second mortise and tenon piece 5 is welded with a second steel component 2, and the inner end of the second mortise and tenon piece 5 is welded with a positioning rod 51, and the second mortise and tenon piece 5 is matched and connected with the first mortise and tenon hole 31, the second mortise and tenon hole 34 and the third mortise and tenon hole 36.

[0023] In this embodiment, the first mortise and tenon member 3, the second mortise and tenon member 5 and the mortise and tenon pin 4 constitute the multi-directionally adjustable quick-connect steel structure mortise and tenon structure body involved in this application.

[0024] The mortise and tenon parts and the mortise and tenon pins 4 are both made of steel, and the steel components are fixedly connected to the mortise and tenon parts by pre-welding.

[0025] Specifically, the three mortise and tenon holes are located in a plane in a top view, and are located in the four directions of up, down, left and right of the first mortise and tenon part 3 together with the first steel component 1 .

[0026] like Figure 1 、 Figure 2 and Figure 3 In the figure, the first mortise and tenon part 3 is set as a rectangular block structure, and the first pin hole 33 is opened at the center of the rectangular block, and the first pin hole 33 is set as a square hole structure, the first mortise and tenon hole 31, the second mortise and tenon hole 34 and the third mortise and tenon hole 36 are all set as cross slot hole structures, and a first positioning hole 32 is opened inside the first mortise and tenon hole 31, a second positioning hole 35 is opened inside the second mortise and tenon hole 34, and a third positioning hole 37 is opened inside the third mortise and tenon hole 36. At the same time, the first positioning hole 32, the second positioning hole 35 and the third positioning hole 37 are all connected to the first pin hole 33.

[0027] Specifically, the first pin hole 33 is located on the upper side of the inner intersection of the three positioning holes, and the outer end of the positioning hole is located at the center of the inner end of the mortise and tenon hole. After the second mortise and tenon part 5 and the mortise and tenon hole are inserted and limited, the inner end face of the second steel component 2 is flush with the outer wall of the first mortise and tenon part 3.

[0028] like Figure 4 In the figure, the mortise and tenon pin 4 is set as a prismatic structure with different widths at both ends, and an elastic gap 41 is opened at the end with the larger width. The end of the mortise and tenon pin 4 with the elastic gap 41 is set as the outer end, and the other end is set as the inner end, and the inner end is inserted into the bottom of the first pin hole 33.

[0029] Specifically, the large end of the mortise and tenon pin 4 is slightly larger than the inner hole width of the first pin hole 33, while the small end is smaller than the inner hole width of the first pin hole 33, so that after insertion, the small end can be smoothly inserted downward into the second pin hole 52, and the large end is hammered to change the shape of the elastic gap 41, and then inserted into the first pin hole 33. At this time, the mortise and tenon pin 4 has internal deformation tension, so that it is firmly inserted into the first pin hole 33.

[0030] like Figure 5 In the figure, the second mortise and tenon 5 is set as a cross block structure, and the outer edge of the second mortise and tenon 5 does not exceed the edge of the second steel component 2. The positioning rod 51 is connected to the center of the second mortise and tenon 5 along the length direction of the second steel component 2, and a second pin hole 52 is opened at the upper end of the positioning rod 51. When the positioning rod 51 is plugged into the positioning hole, the second pin hole 52 corresponds to the first pin hole 33 up and down.

[0031] As a preferred embodiment, by setting a cross block structure of the second mortise and tenon part 5, after being connected to the mortise and tenon hole of the cross slot structure, it is restricted from rotating in the circumferential direction, and then locked and prevented in the linear direction through the positioning rod 51, the second pin hole 52 and the mortise and tenon pin 4, thereby achieving stable riveting.

[0032] When in use, the three mortise and tenon holes on the outside of the first mortise and tenon piece and the positioning holes on the inside of the mortise and tenon holes are used to make the second mortise and tenon piece connect to the corresponding mortise and tenon holes in different directions, thereby realizing the adjustability of the connection direction between the first steel component and the second steel component, and improving the versatility of use; when connecting, the second mortise and tenon piece is plugged into a corresponding mortise and tenon hole, at this time the positioning rod is plugged into the positioning hole, and then the narrow end of the mortise and tenon pin is inserted into the first pin hole until it is inserted into the inside of the second pin hole. At this time, the end of the mortise and tenon pin exposed to the outside is hammered so that its elastic gap is squeezed and reduced by the first pin hole until it completely enters the first pin hole and is flush with the first pin hole, thereby avoiding the use of bolts and nuts and achieving a quick connection effect.

[0033] The multi-directional adjustable quick-connect steel structure mortise and tenon structure of the utility model can effectively solve the problems of connection direction limitations and low connection efficiency of existing steel structure mortise and tenon connectors. It increases the connection multi-directionality of steel structure mortise and tenon connectors on the basis of existing multi-directional adjustable quick-connect steel structure mortise and tenon structure technology, and improves the efficiency of mortise and tenon connections.
