Description

Technical Field

[0001] This utility model relates to the field of steel space frame connection structure technology, and in particular to a spliced ​​steel space frame locking structure. Background Technology

[0002] A steel space frame, or steel structure space frame, is generally made up of rod-like members connected in two opposite directions, four directions in a cross shape, or more directions in a regular pattern. The conventional connection methods include welding and bolting. Since welding is more expensive, most companies use locking structures to connect two, four, or more rod-like members at the nodes with bolts.

[0003] In the prior art, locking structures generally take the form of two-way, four-way, six-way, etc. However, regardless of the form, the rods in the locking structure are generally only connected to the locking structure by bolts, and there is no effective connection between the rods in the locking structure, which makes the overall connection strength of this type of steel space frame with locking structure relatively weak. Utility Model Content

[0004] This application provides a splicing steel space frame locking structure, which can establish a more effective connection between rod-shaped members in opposite directions at the locking structure, thereby improving the overall connection strength of the steel space frame.

[0006] In one possible implementation, the connecting channel is symmetrically provided with guide structures on the inner sides of the first sidewall and the second sidewall, the locking holes are formed on the guide structures, and the guide structures extend along the extension direction of the connecting channel and are symmetrically distributed on the left and right sides of the extension direction. The guide structure is an inclined slope structure, and the thickness of the end of the guide structure near the opening of the connecting channel is less than the thickness of the end near the inner side.

[0007] In one possible implementation, a predetermined distance is provided between the guide structure and the opening of the connecting channel, the predetermined distance being 0.10-0.15 times the length of the connecting channel.

[0008] In one possible implementation, the structural body has symmetrical reinforcing structures on the outer sides of the first and second sidewalls, with the reinforcing structures facing the guide structure.

[0009] In one possible implementation, the reinforcing structure on the outer side of the first sidewall is provided with a first groove adapted to accommodate the first connecting portion, such that after the first connecting portion is installed in place, the outer side of the first connecting portion is flush with the outer side of the reinforcing structure. The reinforcing structure on the outer side of the second sidewall is provided with a second groove suitable for accommodating the second connecting part and the locking nut, so that the second connecting part will not protrude from the second groove after the locking member is installed in place.

[0010] In one possible implementation, the second groove is provided with an elastic plug for sealing the locking nut after it has been locked in place.

[0011] In one possible implementation, the structural body is a rectangular sleeve. After the rod-shaped member is inserted into the communicating channel, the first connecting part abuts against the outside of the first sidewall.

This can further improve the connection strength between the locking member, the rod-shaped member and the structure body. In addition, the guide structure can also force the rod-shaped member and the structure body to form an interference fit connection, which can further improve the connection strength.

The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0020] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0022] refer to Figures 1 to 4 This application provides a splicing steel grid locking structure, including a structural body 10 and a locking member 20. The structural body 10 has a connecting channel 101 for connecting two rod-shaped members located in opposite directions. When the connecting channel 101 is a straight channel, it is used to connect two rod-shaped members distributed in opposite directions in a straight line. When the connecting channel 101 is a cross-shaped channel, it is used to connect four rod-shaped members distributed in opposite directions in a cross shape. The locking member 20 is arc-shaped and includes a first connecting part 21 and a second connecting part 22 symmetrically and vertically connected to both ends of the first connecting part 21. The corner of the connection is a rounded transition. The first connecting part 21 extends along the extension direction of the connecting channel 101. The first sidewall 11 and the second sidewall 12 of the structural body 10 are symmetrically provided with locking holes 102 that cooperate with the second connecting part 22. The locking holes 102 are symmetrically distributed in the extension direction of the connecting channel 101. At the same time, the rod-shaped members have connecting holes that cooperate with the locking holes 102. After the rod-shaped member is inserted into the connecting channel 101, the first connecting part 21 abuts against the outside of the structural body 10, and the second connecting part 22 vertically penetrates the locking hole 102 on the first side wall 11, the connecting hole, and the locking hole 102 on the second side wall 12, and is screwed with a locking nut (not shown in the figure) after penetration. The locking nut abuts against the outside of the structural body 10, that is, the side away from the first connecting part 21. Thus, the effective connection relationship can be established simultaneously between the structural body 10 and the rod-shaped members in opposite directions within the structural body 10 through the cooperation of the locking member 20 and the locking nut. The effective connection relationship is relative to the contact connection, that is, this connection relationship is not just a contact relationship. This makes the node position of the rod-shaped member at the locking structure have better connection strength and structural stability, thereby improving the overall connection strength of the steel space frame.

[0023] In one embodiment, for the two-way locking structure, a combination of Figure 1 The structural body 10 is a rectangular sleeve. After the rod-shaped member is inserted into the communicating channel 101, the first connecting part 21 abuts against the outside of the first side wall 11, and the second connecting part 22 sequentially passes through the locking hole 102 on the first side wall 11, the connecting hole, and the locking hole 102 on the second side wall 12, and is screwed with the locking nut after passing through. The locking nut abuts against the outside of the second side wall 12. The two second connecting parts 22 respectively pass through the rod-shaped members at both ends of the communicating channel 101, thereby establishing an effective connection between the two rod-shaped members and the structural body 10 simultaneously through the locking member 20.

[0024] In one embodiment, for the four-way locking structure, a combination of Figure 3 The structural body 10 is a cross-shaped sleeve, and the connecting channel 101 is a cross-shaped channel. There are two locking members 20, namely a first locking member 210 and a second locking member 220, and the first connecting parts 21 on the two locking members 20 are distributed in a cross shape. After the rod-shaped member is inserted into the communicating channel, the first connecting portion 21 on the first locking member 210 abuts against the outer side of the first sidewall 11, while the second connecting portion 22 on the first locking member 210 sequentially penetrates the locking hole 102 on the first sidewall 11, the connecting hole, and the locking hole 102 on the second sidewall 12, and is screwed with the locking nut after penetration; the first connecting portion 21 on the second locking member 220 abuts against the outer side of the second sidewall 12, while the second connecting portion 22 on the second locking member 220 sequentially penetrates the locking hole 102 on the second sidewall 12, the connecting hole, and the locking hole 102 on the first sidewall 11, and is screwed with the locking nut after penetration. Thus, an effective connection can be established between two rod-shaped members and the structural body 10 in one straight line direction through the first locking member 210, and an effective connection can be established between two rod-shaped members and the same structural body 10 in a perpendicular straight line direction through the second locking member 220.

[0025] In one embodiment, the connecting channel 101 is symmetrically provided with guide structures 13, such as plate-shaped guide structures, on the inner sides of the first sidewall 11 and the second sidewall 12. The locking holes 102 are formed on the guide structures 13. The guide structures 13 extend along the extension direction of the connecting channel 101 and are symmetrically distributed on the left and right sides of the extension direction. That is, there are two mutually symmetrical guide structures 13 in the same straight line direction within the connecting channel 101. The guide structure 13 is an inclined slope structure. The thickness of the end of the guide structure 13 near the opening of the connecting channel 101 is less than the thickness of the end near the inner side. This provides guidance when the rod-shaped member is inserted into the connecting channel 101. It also increases the thickness of the first sidewall 11 and the second sidewall 12 to a certain extent, i.e., increases the depth of the locking hole 102, thereby increasing the contact area between the second connecting part 22 and the structural body 10. This further enhances the connection strength between the locking member 20, the rod-shaped member, and the structural body 10. To ensure the rod-shaped member can be quickly inserted into the connecting channel 101, the thickness of the guide structure 13 cannot be too thick. Generally, the inclination of the guide structure 13 relative to the connecting channel 101 cannot exceed 3 degrees. When the rod-shaped member approaches the middle position of the connecting channel 101, the rod-shaped member and the connecting channel 101 are interference-fitted, further enhancing the connection strength between the rod-shaped member and the structural body 10.

[0026] In one embodiment, a predetermined distance is provided between the guide structure 13 and the opening of the communication channel 101, wherein the predetermined distance is 0.10-0.15 times the length of the communication channel, so as to ensure that the rod-shaped member can first enter the communication channel 101 without obstruction, and then be further inserted to the bottom along the guide structure 13, which facilitates the assembly of the rod-shaped member and the locking structure.

[0027] In one embodiment, the structural body 10 is symmetrically provided with reinforcing structures 14 on the outer sides of the first sidewall 11 and the second sidewall 12, and the reinforcing structures 14 are directly opposite the guide structure. The reinforcing structures can be reinforcing layers or reinforcing plates, thereby further increasing the thickness of the first sidewall 11 and the second sidewall 12 based on the guide structure 13, thereby further increasing the depth of the locking hole 102, increasing the connection contact area between the second connecting part 22 and the structural body 10, and thus further improving the connection strength between the locking member 20, the rod-shaped member and the structural body 10.

[0028] In one embodiment, the reinforcing structure 14 on the outer side of the first sidewall 11 is provided with a first groove 103 suitable for accommodating the first connecting portion 21, such that after the first connecting portion 21 is installed in place, the outer side of the first connecting portion 21 is flush with the outer side of the reinforcing structure 14. Meanwhile, the reinforcing structure 14 on the outer side of the second sidewall 12 is provided with a second groove (not shown in the figure) suitable for accommodating the second connecting part 22 and the locking nut, so that after the locking member 20 is installed in place, the second connecting part 22 will not protrude from the second groove. At this time, the locking nut is also in the second groove and does not protrude from the second groove, thereby protecting the locking member 20 and preventing the locking member 20 from causing potential danger to external objects or personnel.

[0029] More preferably, after the locking nut is tightened in place, the second groove is filled with an elastic plug, such as a rubber plug, to seal and protect the locking nut, so as to facilitate the disassembly and maintenance of the locking structure in the later stage.

[0030] It should be noted that the terms "first" and "second" used in this application are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0031] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
