Abstract
Description
Technical Field
[0001] This application relates to the technical field of steel truss construction, and in particular to a top-pushing beam structure for steel truss. Background Technology
[0002] A guide beam is a temporary auxiliary structure installed at the front end of a beam during beam erection using the incremental launching method. It is a small beam added to the front end of the beam to ensure the longitudinal overturning stability of the beam during movement and to reduce the beam's overhang length, thereby reducing installation stress. It is often constructed by adding detachable members, truss longitudinal beams, or members from existing steel beams.
[0003] The guide beam is quite long, so it is made up of multiple rods connected by multiple screws and nuts. However, the guide beam is long and heavy, so relying solely on the screws and nuts makes the guide beam less stable during use, which greatly reduces the safety of the guide beam during construction. Utility Model Content
[0004] To improve the safety of the guide beam during construction, this application provides a steel truss top-pushing guide beam structure.
[0005] This application provides a steel truss top-pushing beam structure, which adopts the following technical solution:
[0006] A steel truss top-pushing beam structure includes multiple members, with adjacent members connected to each other via a connecting mechanism, the connecting mechanism comprising:
[0007] The connecting seat is formed by fixing multiple plates and has multiple connecting grooves. One end of the rod is inserted into the connecting groove for positioning.
[0008] The connector passes through the connector seat and the rod body;
[0009] The connecting screw passes through the connector and the rod body and is threaded with a connecting nut for fixing.
[0010] By adopting the above technical solution, during splicing, one end of the rod body is inserted into the connecting groove, and then the connector is inserted into the connecting seat and the rod body for positioning. The connecting screw is passed through the connector, and then the connecting nut is threaded onto the connecting screw for positioning. Therefore, when the rod body is under force, the connecting groove, connector, and connecting screw can support and position the rod body, thereby greatly improving the stability of the guide beam after splicing and improving the safety of the diversion construction.
[0011] Optionally, the connector includes a connecting tube and an abutment ring coaxially disposed therebetween, the connecting tube passing through the connecting seat and the rod body, and the abutment ring abutting against the connecting seat for positioning.
[0012] By adopting the above technical solution, the connecting pipe is inserted and installed onto the connecting seat and the rod body. At the same time, the abutment ring is pushed against the connecting seat for positioning, and the connecting screw passes through the connecting pipe to position the connecting component. This improves the convenience of connecting component installation and the stability after installation, and improves the efficiency and safety of guide beam construction.
[0013] Optionally, the head of the connecting screw is positioned against the abutment ring, the connecting screw is fitted with a connecting ring, and the connecting nut is positioned against the connecting ring.
[0014] By adopting the above technical solution, the abutment ring is positioned against one side wall of the connecting seat. Then, the connecting screw is passed through the connecting pipe, and the connecting ring is sleeved on the connecting screw. The connecting nut is threaded onto the connecting screw, so that the head of the connecting screw presses against the abutment ring for positioning. The connecting nut pushes the connecting ring against the side wall of the connecting seat away from the abutment ring, thereby achieving the positioning of the connecting parts, improving the stability after connection, and improving the safety of guide beam construction.
[0015] Optionally, the connecting pipe is provided with a guide angle to facilitate the passage of the connecting seat and the rod body.
[0016] By adopting the above technical solutions, the convenience of connecting pipe insertion process is improved, and the construction efficiency of guide beams is increased.
[0017] Optionally, multiple rods are arranged horizontally at intervals. Each rod includes multiple layers of rod bodies arranged vertically at intervals, a supporting vertical rod and a supporting diagonal rod that are connected to the adjacent two layers of rod bodies for support by a connecting mechanism. The connecting groove is provided with a support mechanism for supporting and positioning the supporting vertical rod or the supporting diagonal rod.
[0018] By adopting the above technical solution, the multi-layered poles arranged vertically at intervals cooperate to form a frame structure. At the same time, the supporting vertical poles and supporting diagonal poles connect two adjacent poles into one unit. Support is achieved in multiple directions, including vertical and inclined directions, which improves the stability of the guide beam after installation. Moreover, the support mechanism can also support the supporting vertical poles or supporting diagonal poles, enabling multi-point support, which further improves the stability of the guide beam after installation and enhances the construction safety of the guide beam.
[0019] Optionally, the support mechanism includes:
[0020] The support block is slidably mounted on the connecting groove in a direction that is close to or far from the support vertical bar or support diagonal bar;
[0021] The pushing component is used to push the support block against the support vertical rod or support diagonal rod for support and positioning.
[0022] By adopting the above technical solution, after the support vertical rod is installed onto the connecting groove through the connecting mechanism, the support block is slidably installed onto the connecting groove, and the pushing component pushes the support block against the support vertical rod, and the support vertical rod is positioned against the connecting groove. At the same time, the support diagonal rod is operated in the same way, thereby further improving the stability of the support vertical rod or support diagonal rod, and also being able to adapt to support the support vertical rod or support diagonal rod at different positions and angles, thus improving the safety of guide beam construction.
[0023] Optionally, the pushing component includes:
[0024] The fixing block is set on the connecting groove, and the top and bottom of the support block are provided with push surfaces that are close to each other and inclined. The height of the push surface on the side closer to the support rod is lower than the height on the side farther away from the support rod.
[0025] The push screw is threaded onto the connecting seat and pushes the support block against the support rod for positioning.
[0026] By adopting the above technical solution, after the support block is placed on the connecting groove, the pushing surfaces on the support block and the fixed block are in contact, and the height of the pushing surface near the end of the support rod is relatively high, so that the support block tends to move closer to the support rod under the action of gravity. At the same time, turning the pushing screw pushes the support block closer to the support rod, and the support block moves down under the action of gravity, so that the support block presses against the support rod for positioning. Moreover, the pushing force of the support rod on the support block is partially offset by the pushing surface, which greatly reduces the back push force on the support block, improves the support and positioning effect of the pushing screw on the support block, and improves the safety during the construction of the guide beam.
[0027] Optionally, the support block is provided with a bracing surface to facilitate the fitting of the support rod.
[0028] By adopting the above technical solutions, the support effect was further improved, and the safety during the construction of the guide beam was enhanced.
[0029] Optionally, the connecting groove may be detachably equipped with a connecting rod to facilitate the connection of steel truss beams.
[0030] By adopting the above technical solution, the connecting rod is easy to connect with the steel truss beam, and different types of connecting rods can be replaced when the steel truss beam needs to be connected, which improves the convenience of the construction process and the construction efficiency of the guide beam.
[0031] In summary, this application includes at least one of the following beneficial technical effects:
[0032] 1. The connecting groove, connectors, and connecting screws can simultaneously support and position the rod body, thereby greatly improving the stability of the guide beam after splicing and enhancing the safety of the diversion construction. Attached Figure Description

[0037] The following provides a further detailed description of this application.
[0038] This application discloses a top-pushing beam structure for a steel truss girder.
[0039] Reference Figure 1 The top push beam structure of the steel truss beam includes multiple rods 1 spaced apart in the horizontal direction. The rod 1 closest to the steel truss beam is connected to the steel truss beam. The bottoms of the multiple rods 1 are flush and their height decreases as the distance from the steel truss beam increases. Adjacent rods 1 are connected to each other by a connecting mechanism 2.
[0040] Each rod body 1 includes multiple layers of rod bodies 11 arranged vertically at intervals, and supporting vertical rods 12 and supporting diagonal rods 13 that are connected to adjacent two layers of rod bodies 11 through connecting mechanisms 2. The rod bodies 11 on the same horizontal level are also connected to each other through connecting mechanisms 2.
[0041] Reference Figure 1 and Figure 2In this embodiment, the number of rod bodies 11 is two layers. The connecting mechanism 2 includes a connecting seat 21, a connecting piece 3, and a connecting screw 4. The connecting seat 21 is formed by welding and fixing multiple plates and has multiple connecting grooves 22. The connecting grooves 22 include slot 1 23 located on the upper surface of the connecting seat 21 and slot 24 located on the opposite side walls of the connecting seat 21 and in a horizontal state. The two rod bodies 11 on the same horizontal plane are respectively inserted into the two slots 24. The slots 24 are adapted to the size of the rod bodies 11. Slot 1 23 located at the bottom of the connecting seat 21 is located at the upper layer of rod bodies 11. The supporting vertical rod 12 is in a vertical state and its two ends are inserted into the slots 23 of the two connecting seats 21 arranged in the vertical direction. The two ends of the supporting diagonal rod 13 are respectively inserted into the slots 23 on the two connecting seats 21 that are spaced apart and staggered.
[0042] The connector 3 and the connecting screw 4 have the same structure at the main body 11, the supporting vertical rod 12 and the supporting diagonal rod 13. The following explanation takes the main body 11 as an example. At the same time, the connecting grooves 22 of the two connecting seats 21 near the steel truss beam are also fixedly installed with connecting rods 14 by connector 3 and connecting screw 4. The connecting rods 14 are used to fix the connection with the steel truss beam. When connecting different steel trusses, the matching connecting rods 14 are replaced.
[0043] Reference Figure 2 and Figure 3 The connector 3 includes a connecting tube 31 and an abutment ring 32 coaxially arranged. The abutment ring 32 is located on the outer wall of one end of the connecting tube 31. The connecting tube 31 is inserted into the connecting seat 21 and the rod body 11. The abutment ring 32 is positioned against the side wall of the connecting seat 21. The end of the connecting tube 31 away from the abutment ring 32 is located inside the connecting seat 21. The connecting tube 31 is provided with a guide angle to facilitate insertion and installation into the connecting seat 21 and the rod body 11.
[0044] The connecting screw 4 passes through the connecting tube 31 and its head presses against the abutment ring 32 for positioning. The connecting screw 4 is fitted with a connecting ring 42 and threaded with a connecting nut 41. The connecting nut 41 pushes the connecting ring 42 against the side wall of the connecting seat 21 away from the abutment ring 32 for positioning.
[0045] Reference Figure 1 and Figure 2 The slot 24 abuts against the main body 11 of the rod, and the connector 3 is inserted into the connector 21 and the main body 11 of the rod. At the same time, the connecting screw 4 works together to support and position the main body 11 of the rod. In the same way, multiple rods 1 can be fixed, which improves the safety of the guide beam construction process.
[0046] The slot 23 is provided with a support mechanism 5 for supporting and positioning the support vertical rod 12 or the support diagonal rod 13. When only one support vertical rod 12 is inserted into the slot 23, two support mechanisms 5 are provided and are positioned against the opposite side walls of the support vertical rod 12. When two support diagonal rods 13 and one support vertical rod 12 are inserted into the slot 23, two support mechanisms 5 are provided and are used to support and position the two support diagonal rods 13. The support vertical rod 12 is located between the two support diagonal rods 13 and is positioned against the side walls of the two support diagonal rods 13. When only one support diagonal rod 13 exists, only one support mechanism 5 is required.
[0047] Reference Figures 1-3 The following explanation uses the support mechanism 5, which supports the support rod 13, as an example. The support mechanism 5 includes a support block 51 and a pushing component 6. The support block 51 is horizontally slidably installed on the slot 23 and moves closer to or away from the support rod 13. The top of the support block 51 and the side closer to the support rod 13 have a bracing surface 52 that fits against the support rod 13. When the support block 51 supports the support vertical rod 12, it is supported and positioned by the side wall close to the support vertical rod 12. When the support block 51 supports the support rod 13, it is supported and positioned by the bracing surface 52.
[0048] The pushing component 6 includes a fixed block 61 and a pushing screw 62. The fixed block 61 is fixedly installed on the bottom of the connecting groove 22. The support block 51 is located above the fixed block 61, and the bottom and top of the fixed block 61 are provided with inclined pushing surfaces 53 that fit together. The height of the pushing surface 53 on the side closer to the support rod 13 is lower than the height on the side away from the support rod 13. When the support block 51 is on the connecting groove 22, it will tilt downwards and approach the support rod 13 under the action of gravity. The inclined support surface 52 presses against the support rod 13 for positioning. The pushing screw 62 is threaded to the connecting seat 21 and presses against the support block 51. Tightening the pushing screw 62 can push the support block 51 closer to the support rod 13, so that the inclined support surface 52 presses against the support rod 13 for positioning.
[0049] The working principle of this application embodiment is as follows:
[0050] The support vertical rod 12 is inserted and installed into slot 23. Then, the connecting pipe 31 is inserted and installed into the connecting seat 21 and the support vertical rod 12, so that the abutment ring 32 abuts against the connecting seat 21 for positioning. Next, the connecting ring 42 is sleeved onto the connecting screw 4, and the connecting nut 41 is threaded onto the connecting screw 4, so that the head of the connecting screw 4 presses against the abutment ring 32 and the connecting nut 41 presses against the connecting ring 42 for positioning, thereby connecting the support vertical rod 12 to the connecting seat 21. At the same time, the support diagonal rod 13 is connected to the connecting seat 21 using the same method, and the rod body 11 is connected to slot 24, thereby improving the safety and construction efficiency during the construction of the guide beam.
[0051] Place the support block 51 on the slot 23, and push the screw 62 to rotate so that the support block 51 presses against the support diagonal rod 13. At the same time, when the support vertical rod 12 needs to be supported, the same method is used to achieve support, thereby further improving the safety of the guide beam construction.
[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
