[0002] A truss is a supporting beam structure made of steel pipes connected by welding, riveting, or bolting. It is primarily used as a load-bearing and supporting member in structural engineering. It is used to share loads, provide support and stability, reduce material usage, and effectively transfer loads to supporting points. A truss is typically composed of multiple sets of primary and secondary trusses. The typical construction method involves precisely aligning the secondary trusses with the primary trusses and then connecting them using welding or high-strength bolts.

[0003] However, when the secondary truss is connected to the main truss, position deviation is likely to occur, resulting in excessively large welds, slow installation progress, and greater safety risks.

[0004] In view of this, how to solve the defects in the above technical solutions has become one of the problems to be solved urgently in the field of building component technology. Utility Model Content

[0005] In view of the problems existing in the background technology, the utility model provides, on the one hand, a connection structure for the main truss and secondary truss of a steel structure, including a main truss and a secondary truss connected to the main truss through a connecting mechanism, wherein the connecting mechanism includes a connecting plate and a connecting member fixedly connected to the connecting plate, the connecting plate is tightly attached to the upper and lower steel plate end faces of the main truss, and is fixedly connected by fastening bolts.

[0006] Optionally, a through slot is provided on the Y-direction of the connecting member for the vertical plate of the secondary truss to extend into, and the vertical plate of the truss abuts against the inner wall of the through slot;

[0007] The connecting member is provided with a through positioning groove in the X direction; when the vertical plate of the truss abuts against the inner wall of the through groove, the positioning block arranged on the secondary truss extends into the positioning groove to perform a snap connection, and is fixed by bolts.

[0008] Optionally, the connecting member further includes an adjusting member, the screw of the adjusting member cooperates with the internal thread in the hole of the connecting member to form a spiral transmission, and the other end of the screw extends out of the connecting member and into a groove body opened on the connecting member.

[0009] Optionally, a clamping block is provided on the end surface of the screw located in the trough body and is integrated therewith, and the clamping block is used in conjunction with the clamping groove on the secondary truss to perform a clamping connection.

[0010] Optionally, at least one set of sliding grooves is provided in the connecting plate at a position opposite to the connecting member, a slider is slidably installed in the sliding groove, and a spring is installed on the end surface of the slider at a position away from the connecting member.

[0011] Optionally, a connecting seat is provided on the end surface of the slider extending out of the slide groove and is integrated with the slider, and is installed on the end surface of the connecting piece by a high-strength fastening bolt.

[0012] In summary, the beneficial effects of the present invention are:

[0013] (1) The utility model has a simple structure and is easy to install. During installation, only a small number of fastening bolts are needed to achieve the installation between the main truss and the secondary truss, thereby improving work efficiency.

[0014] (2) The present invention solves the problem of positional deviation when the secondary truss is connected to the main truss, which leads to excessive welds, by adding a connection mechanism. During installation, it is only necessary to insert the vertical plate of the secondary truss into the through groove 044. At this time, the vertical plate of the secondary truss is in conflict with the inner wall of the through groove 044. Then, by rotating the screw 0411, the screw is driven to drive the clamping block 045 into the clamping groove on the secondary truss, so that the clamping block is clamped and connected with the clamping groove, thereby realizing the connection between the main truss and the secondary truss; thus, the problem of positional deviation when the main truss and the secondary truss are connected is effectively prevented.

[0032] like Figures 1 to 5 As shown, this embodiment provides a connection structure for the main truss and secondary truss of a steel structure, including a main truss 1, and a secondary truss 7 connected to the main truss 1 through a connection mechanism 2, the connection mechanism 2 includes a connection plate 021 and a connection member 4 fixedly connected to the connection plate 021, the connection plate 021 is tightly attached to the upper and lower steel plate end surfaces of the main truss, and is fixedly connected by fastening bolts 3, thereby realizing a fixed connection between the connection mechanism 2 and the main truss 1.

[0033] Trusses are usually made up of multiple sets of main trusses and secondary trusses. The usual construction method is to accurately connect the secondary trusses to the main trusses, and then connect the main trusses and secondary trusses by welding or high-strength fastening bolts. However, when the secondary trusses are connected to the main trusses, the position is easily offset, resulting in excessively large welds, slow installation progress, and greater safety risks. To solve the above technical problems, please refer to Figure 1-5 As shown, the Y-direction of the connecting member 4 is provided with a through slot 044 for the vertical plate of the secondary truss 7 to extend into, so that the vertical plate of the truss abuts against the inner wall of the through slot 044;

[0034] The connector 4 has a through positioning slot 043 extending in the X-direction. When the vertical plate of the truss abuts the inner wall of the through slot 044, the positioning block 5 provided on the secondary truss 7 extends into the positioning slot 043, engaging the connection, and the connection is fixed by bolts 6. This improves the stability of the connection between the connector and the secondary truss 7.

[0035] In this embodiment, in order to improve the stability of the connection between the secondary truss and the connecting member 4, when the installation between the connecting member and the secondary truss is completed, it is only necessary to pass the bolts 6 through the top plate of the secondary truss 7 from top to bottom, and extend them into the threaded holes of the connecting member to perform threaded connection, and tighten the fastening nuts onto the bolts 6, thereby achieving the stability of the connection between the secondary truss and the connecting member 4.

[0036] Furthermore, the connecting member 4 also includes an adjusting member 041, and the adjusting member 041 includes a screw 0411. The screw 0411 is used in conjunction with the internal thread in the hole of the connecting member 4 to form a spiral transmission. By rotating the screw 0411, the screw is driven out of the hole of the connecting member 4 and extends into the groove body 042 opened on the connecting member 4.

[0037] Furthermore, a snap-fit ​​block 045 is provided on the end surface of the screw rod 0411 in the trough body 042 and is integrated therewith, and the snap-fit ​​block 045 cooperates with the snap-fit ​​groove on the secondary truss to perform snap-fit ​​connection.

[0038] In this embodiment, in actual application, in order to prevent the main truss and the secondary truss from being offset when connected, when the main truss and the secondary truss need to be connected, the vertical plate of the secondary truss only needs to be inserted into the through-groove 044. At this time, the vertical plate of the secondary truss abuts against the inner wall of the through-groove 044. Then, by rotating the screw 0411, the driving screw drives the clamping block 045 to extend into the clamping groove on the secondary truss, so that the clamping block is clamped and connected with the clamping groove, thereby realizing the connection between the main truss and the secondary truss.

[0039] Finally, the bolts 6 are passed through the top plate of the secondary truss 7 from top to bottom, and extended into the threaded holes of the connector for threaded connection, and the fastening nuts are tightened onto the bolts 6 to achieve the stability of the connection between the secondary truss and the connector 4.

[0040] Furthermore, at least one set of slide grooves 022 is provided in the connecting plate 021 at a position relative to the connecting member 4, a slider 023 is slidably installed in the slide groove 022, and the slider 023 slides in the slide groove 022, and a spring 024 is fixedly installed on the end surface of the slider 023 at a position away from the connecting member 4 by means of a fixed connection such as a fastening screw, and the spring seat of the spring 024 is fixedly installed in the inner wall of the slide groove 022 by means of a fixed connection such as a fastening screw.

[0041] Furthermore, a connecting seat 025 is provided on the end surface of the slider 023 extending out of the slide groove 022 and is integrated therewith, and is mounted on the end surface of the connecting member by high-strength fastening bolts.

[0042] In this embodiment, the connecting plate 021 is fixedly mounted on the end surface of the connecting member 4 by high-strength fastening bolts;

[0043] In actual use, if the main truss and secondary truss are installed in an inconvenient position, the connecting member can be pulled to cause the slider 023 to slide out of the slide groove 022, thereby moving the connecting member 4. Once the slider is moved to a more convenient position for installation, an external fixing mechanism can be used to fix the slider. By increasing the distance between the main truss and secondary truss, the connection between the main truss and secondary truss is further facilitated. After the secondary truss is installed, the external fixing structure is removed and the secondary truss is pushed firmly until the slider is fully pushed into the slide groove.

[0044] The use process and working principle of this utility model:

[0045] When the present invention is in use, when it is necessary to connect the main truss and the secondary truss, it is only necessary to fix the connecting mechanism 2 on the main truss 1 by means of the fastening bolts 3 (high-strength fastening bolts are preferably used), and then insert the vertical plate of the secondary truss into the through-groove 044. At this time, the vertical plate of the secondary truss contacts the inner wall of the through-groove 044. Then, by rotating the screw 0411, the driving screw drives the clamping block 045 to extend into the clamping groove on the secondary truss, so that the clamping block is clamped and connected with the clamping groove, thereby realizing the connection between the main truss and the secondary truss.

[0046] Finally, the bolts 6 are passed through the top plate of the secondary truss 7 from top to bottom, and extended into the threaded holes of the connector for threaded connection, and the fastening nuts are tightened onto the bolts 6 to achieve the stability of the connection between the secondary truss and the connector 4.

[0047] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to be limiting. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that modifications or equivalent substitutions to the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
