Technical Field

[0001] This application relates to the field of Bailey beams, and in particular to a node strengthening structure for a Bailey beam column bracket. Background Art

[0002] The Bailey beam is a support structure form with simple structure, light weight, wide application, strong adaptability and strong interchangeability. It has been widely used and highly praised in bridge construction and other engineering fields due to its unique advantages.

[0003] The existing Bailey beam support system is a complex and flexible structural system, which usually includes Bailey beams, support columns and fixed connectors. Among them, the Bailey beams are horizontally arranged on the tops of the support columns, and the fixed connectors are mainly used to connect the Bailey beams. Each structure in the Bailey beam support system cooperates with each other to jointly ensure the stability and safety of the support system and meet the requirements of various engineering constructions.

[0004] In view of the above-mentioned existing technology, when the Bailey beam support system spans a relatively long length, the nodes at the connection between the Bailey beam and the bottom support column are prone to local damage caused by stress concentration, which is not convenient for ensuring the support stability of the Bailey beam support system. Summary of the Utility Model

[0005] In order to make it difficult for the nodes at the connection between the Bailey beam and the bottom support column to appear local damage caused by stress concentration when the Bailey beam support system spans a relatively long length, and to facilitate ensuring the support stability of the Bailey beam support system, this application provides a node strengthening structure for a Bailey beam column bracket.

[0006] The node strengthening structure for a Bailey beam column bracket provided by this application adopts the following technical solutions:

[0007] A node strengthening structure for a Bailey beam column bracket includes a strengthening support member fixedly arranged on the Bailey beam. The strengthening support member includes a top beam, a bottom beam and support beams. The top beam and the bottom beam respectively abut against two cross beams at the top and bottom of the Bailey beam. The support beams are vertically arranged and a plurality of them are distributed along the length direction of the top beam. One end of each support beam is fixedly installed on the top beam and the other end is fixedly installed on the bottom beam.

[0008] By adopting the above technical solution, when the Bailey beam support system spans a relatively long length, the top beam and the bottom beam of the strengthening support are respectively fixed to the two cross beams at the top and bottom of the Bailey beam by welding or bolts, and the strengthening support is located at the position of the node where the Bailey beam is connected to the bottom support column, so that the strengthening support plays a role in strengthening and supporting the local part of the Bailey beam, making it difficult for the node where the Bailey beam is connected to the bottom support column to appear local damage caused by stress concentration, and thus facilitating the guarantee of the support stability of the Bailey beam support system.

[0009] Optionally, the longitudinal sections of the top beam and the bottom beam are both in the shape of an I-beam.

One end of the first beam body is fixedly installed on the bottom beam, and the other end is provided with an adjustment groove extending along its own length direction. One end of the second beam body is fixedly installed on the top beam, and the other end is slidably fitted in the adjustment groove. The first beam body is fixed to the second beam body through a connecting piece.

[0015] Optionally, the first beam body is provided with a fixing hole horizontally penetrating through it, the second beam body is provided with a plurality of adjustment holes horizontally penetrating through it and evenly distributed along its own length direction, and the connecting piece includes a connecting bolt, and the connecting bolt passes through the fixing hole and one of the adjustment holes to fix the first beam body and the second beam body.

[0016] By adopting the above technical solution, the length of the support beam can be adjusted by screwing the connecting bolt and making the fixing hole correspond to adjustment holes at different positions and then fixing, which is convenient and fast.

[0017] Optionally, the cross-section of the first beam body is in the shape of an I-beam. There are two adjustment grooves, which are respectively located on both sides of the first beam body in the thickness direction. The adjacent second beam bodies are respectively located in the adjustment grooves on two different sides of the adjacent first beam bodies.

[0034] The following will further describe the present application in detail Figures 1-5 in conjunction with the accompanying drawings.

[0035] The embodiments of the present application disclose a strengthened structure for the node of a Bailey beam column bracket.

[0036] Embodiment 1.

[0037] Referring to Figure 1 and Figure 2 , the strengthened structure for the node of the Bailey beam column bracket includes a strengthening support member, and the strengthening support member is fixedly arranged on the Bailey beam 15 by welding or bolts. Specifically, the strengthening support member includes a top beam 1, a bottom beam 2, and a support beam 3.

[0038] Referring to Figure 2 and Figure 3, wherein, the Bailey beam 15 includes two horizontally arranged cross beams 151. The top beam 1 and the bottom beam 2 are both horizontally arranged and respectively abut against the two cross beams 151 at the top and bottom of the Bailey beam 15. The longitudinal sections of the top beam 1 and the bottom beam 2 are both in the shape of an "I", so as to reduce the material cost on the premise of ensuring the support strength of the strengthening support member. The top beam 1 and the bottom beam 2 are fixed to the two cross beams 151 of the Bailey beam 15 by welding or bolts. In the embodiment of the present application, the fixing method between the top beam 1 and the bottom beam 2 and the two cross beams 151 of the Bailey beam 15 is welding.

[0039] Continue to refer to Figure 2 and Figure 3 , each support beam 3 is vertically arranged, and a plurality of them are evenly distributed along the length direction of the top beam 1. In the embodiment of the present application, the number of support beams 3 is selected as three. One end of each support beam 3 is fixedly installed on the top beam 1 by welding, and the other end is fixedly installed on the bottom beam 2 by welding. The cross section of each support beam 3 is in the shape of an "I", so as to reduce the material cost on the premise of ensuring the support strength of the strengthening support member.

[0040] Refer to Figure 2 , to further ensure the connection strength between the support beam 3 and the top beam 1 and the bottom beam 2, a top strengthening rod 4 is arranged between each support beam 3 and the top beam 1, and both ends of the top strengthening rod 4 are fixedly welded to the support beam 3 and the top beam 1 respectively. A bottom strengthening rod 5 is arranged between each support beam 3 and the bottom beam 2, and both ends of the bottom strengthening rod 5 are fixedly welded to the support beam 3 and the bottom beam 2 respectively.

[0041] The implementation principle of Embodiment 1 of the present application is as follows: In the Bailey beam 15 support system, when the span length of the Bailey beam 15 support system is relatively long, the strengthening support member is moved to the position of the node where the Bailey beam 15 is connected to the bottom support column, and the top beam 1 and the bottom beam 2 of the strengthening support member are respectively fixedly welded to the two cross beams 151 at the top and bottom of the Bailey beam 15, so that the strengthening support member plays a role in strengthening the local support of the Bailey beam 15, making it difficult for the node where the Bailey beam 15 is connected to the bottom support column to appear local damage caused by stress concentration, and thus facilitating to ensure the support stability of the Bailey beam 15 support system.

[0042] Embodiment 2.

[0043] The main difference between the embodiment of the present application and Embodiment 1 lies in the different structures of the support beams 3. Refer to Figure 4, in the embodiment of the present application, the support beam 3 includes a first beam body 31 and a second beam body 32. Among them, one end of the first beam body 31 is fixedly installed on the bottom beam 2 by welding. The cross-section of the first beam body 31 is in the shape of an I-beam. The first beam body 31 includes a first web 311 and two first flanges 312 respectively fixedly connected to both sides of the first web 311. The area surrounded by the first web 311 and the two first flanges 312 forms two adjustment slots, and the two adjustment slots are respectively located on both sides of the first web 311, that is, on both sides in the thickness direction of the first beam body 31.

[0044] Continue to refer to Figure 4 , one end of the second beam body 32 is fixedly installed on the top beam 1, and the other end is slidably fitted in one of the adjustment slots. The cross-section of the second beam body 32 is in the shape of a U, and the second beam body 32 is fixed to the first beam body 31 through a connecting member. Let the adjustment slot on one side of the first web 311 be the first adjustment slot 6, and the adjustment slot on the other side be the second adjustment slot 7. Adjacent second beam bodies 32 are respectively slidably fitted in the first adjustment slot 6 and the second adjustment slot 7 of adjacent first beam bodies 31. To ensure the overall stability of the reinforcement support after the position of the second beam body 32 and the first beam body 31 is adjusted.

[0045] Continue to refer to Figure 4 , the first web 311 is provided with a fixing hole 8 penetrating horizontally, and the second beam body 32 is provided with a plurality of adjustment holes 9 evenly distributed along its own length direction and penetrating horizontally. The connecting member includes a connecting bolt 10. The connecting bolt 10 passes through the fixing hole 8 and one of the adjustment holes 9 to achieve firm fixation between the first beam body 31 and the second beam body 32 through cooperation with a nut.

[0046] The implementation principle of Embodiment 2 of the present application is the same as that of Embodiment 1. The main difference is that the length of the support beam 3 is adjusted by the sliding fit of the second beam body 32 in the adjustment slot and the fixation of the connecting bolt 10 between the first beam body 31 and the second beam body 32, so as to facilitate the adaptation to Bailey beams 15 of different heights and is beneficial to improving the applicability of the reinforcement support.

[0047] Embodiment 3.

[0048] Refer to Figure 5, The main difference between the embodiment of the present application and Embodiment 1 is that the bottom beam 2 is further provided with two clamping rods 11. Specifically, the clamping rod 11 includes a horizontal portion 111 and a vertical portion 112 fixedly connected to one end of the horizontal portion 111. Among them, the bottom beam 2 is fixedly connected with a clamping slide bar 12 extending along its own length direction. A clamping chute 13 penetrating horizontally is opened at the bottom of the horizontal portion 111. The longitudinal cross-sections of the clamping slide bar 12 and the clamping chute 13 are both in the shape of a dovetail. The clamping slide bar 12 passes through and is slidably matched with the clamping chutes 13 of the two horizontal portions 111 to realize the stable sliding of the two clamping rods 11 along the length direction of the bottom beam 2. The horizontal portion 111 is firmly fixed to the bottom beam 2 through a fixing bolt 14 that is threadedly engaged with itself and abuts against the clamping slide bar 12. That is, the fixing between the clamping rod 11 and the bottom beam 2 is realized through the fixing bolt 14.

[0049] The implementation principle of Embodiment 3 of the present application is the same as that of Embodiment 1. The main difference is that after moving the two clamping rods 11 so that the vertical portions 112 of the two clamping rods 11 abut against the positions of other components at the bottom of the Bailey beam 15, then by screwing the fixing bolt 14, the position of the clamping rod 11 is fixed, so that the two clamping rods 11 play a further limiting role in the position of the strengthening support member, which is beneficial to fully ensure the stability of the position of the strengthening support member during and after installation.

[0050] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
