Description

Technical Field

[0001] The present application relates to the technical field of prefabricated buildings, and in particular to a prefabricated in-situ support. Background Art

[0002] The in-situ support method is relatively common in the construction of in-situ box girders, mainly including full hall supports and steel pipe column Bailey beams. In mountain bridge construction, due to special geological conditions, if the longitudinal slope and transverse slope are relatively large, it is difficult to unify the support form, and a support system with various combined forms will be used.

[0003] After the in-situ support uses steel columns and Bailey frames as supports, a scaffold can also be installed on the Bailey frame. The structures of the Bailey frame and the scaffold are completely different. When installing on the scaffold, the vertical poles need to be fixedly installed on the Bailey frame, using welding or bolt fixing methods, and the installation speed needs to be improved. Summary of the Invention

[0004] In order to further improve the assembly speed, the present application provides a prefabricated in-situ support.

[0005] The present application provides a prefabricated in-situ support, adopting the following technical solutions:

[0006] A prefabricated in-situ support includes upper and lower support parts. The lower support part includes steel columns and Bailey frames fixedly installed on the steel columns. The upper support part includes a scaffold. Cross beams are arranged at intervals on the Bailey frame. The lower ends of the vertical poles of the scaffold are fixedly installed with bases, and the bases are clamped with the cross beams.

[0007] The Bailey frame is provided with a positioning component. The positioning component includes a mounting plate and a positioning plate. The positioning plate is rotatably installed on the mounting plate. The mounting plate is installed between the two cross beams. The positioning plates are located on both sides in the length direction of the mounting plate. The positioning plates are rotated to abut against the cross beams, and a fixing component is further included for fixing the mounting plate.

[0008] By adopting the above technical solutions, the in-situ support is composed of upper and lower support parts. The lower support part is composed of steel columns and Bailey frames, providing a stable support foundation. The upper support part is a scaffold, which is quickly assembled by clamping the base with the cross beam on the Bailey frame. Because the cross beams are arranged at intervals on the Bailey frame, the design of the positioning component can quickly determine the distribution position of the cross beams and has a preliminary fixing effect on the cross beams, accelerating the assembly speed of the in-situ support, and the cross beams can be further fixed by the fixing component.

[0009] Optionally, there is a gap between the mounting plate and the cross beam. The fixing component includes a fixing plate which is clamped between the mounting plate and the cross beam. One mounting plate corresponds to two fixing plates, and the fixing plate is provided with a fixing groove for the positioning plate to be clamped into.

[0010] By adopting the above technical solution, the fixing component includes a fixing plate which is clamped into the gap between the mounting plate and the cross beam, and the positioning plate is clamped by the fixing groove, so that the horizontal position of the mounting plate is fixed, and the positioning plate can also be fixed, making the cross beam fixed on the Bailey truss.

[0011] Optionally, the cross beam includes an upper cross plate, a lower cross plate and a vertical plate. The upper end of the vertical plate is fixedly connected to the upper cross plate, and the lower end of the vertical plate is fixedly connected to the lower cross plate.

[0012] By adopting the above technical solution, the cross beam is composed of an upper cross plate, a lower cross plate and a vertical plate. The vertical plate is fixedly connected to the upper cross plate and the lower cross plate respectively up and down, forming a stable frame structure.

[0013] Optionally, the fixing component further includes a fixing rod which is installed on the fixing plate. A fixing block is installed on the fixing rod, and the fixing block abuts against the lower surface of the upper cross plate.

[0014] By adopting the above technical solution, the fixing rod is installed on the fixing plate, the fixing block is installed on the fixing rod, and the fixing block abuts against the lower surface of the upper cross plate, thereby further strengthening the mounting plate and preventing the mounting plate from leaving the Bailey truss upward.

[0015] Optionally, a limiting block is fixedly connected to the lower end of the fixing rod, and a limiting groove is provided on the fixing plate, and the limiting block slides into the limiting groove.

[0016] By adopting the above technical solution, the fixing plate can be installed first and then the fixing rod, ensuring the stability and accuracy of the fixing rod during the installation process, preventing the shaking and deviation of the fixing rod, and improving the overall stability of the bracket.

[0017] Optionally, a connecting rod is detachably installed on the fixing plate, and a lower pressing plate for pressing against the base is fixedly connected to the connecting rod.

[0018] By adopting the above technical solution, a connecting rod is detachably installed on the fixing plate, and a lower pressing plate for pressing against the base is fixedly connected to the connecting rod. By adjusting the length of the connecting rod, the tightening degree of the base can be adjusted.

[0019] Optionally, the connecting rod is threadedly connected to the fixing plate.

[0020] By adopting the above technical solution, this connection method has the advantages of simple structure, convenient operation, firm connection, etc., facilitating the operation and adjustment of construction workers. At the same time, the threaded connection also ensures the stability and reliability of the connecting rod during use.

[0021] Optionally, the positioning plate is fixedly connected with a rotating shaft, and one end of the rotating shaft is rotatably installed on the mounting plate.

[0022] By adopting the above technical solution, the positioning plate is rotatably installed on the mounting plate through the fixedly connected rotating shaft, enabling the flexible rotation of the positioning plate.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. Adding a positioning component and a fixing component enables the cross beam to be quickly installed and fixed. The cross beam provides stable support for the installation of the scaffolding on the Bailey truss, accelerating the installation speed of the cast-in-place support and ensuring the stability and safety of the cast-in-place support during construction;

[0025] 2. After the positioning plate initially fixes the mounting plate, the fixing plate and the fixing rod can further fix the mounting plate, enabling the cross beam to be accurately and stably installed on the Bailey truss. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figures 1-6 This application is described in further detail.

[0034] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention and are not all possible implementations. Those skilled in the art can fully combine the embodiments of the present invention to derive other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0035] Reference Figure 1 and Figure 2 The prefabricated cast-in-place support provided in the embodiments of the present application comprises upper and lower support portions. The lower support portion comprises a steel column 1 and a Bailey frame 2 fixedly mounted on the steel column 1. The upper support portion comprises a scaffold 3, with crossbeams 50 arranged at intervals on the Bailey frame 2. The lower ends of the vertical poles of the scaffold 3 are fixedly mounted with a base 4 having an inverted U-shaped cross-section, and the base 4 is clamped to the crossbeam 50.

[0036] Reference Figure 3 The Bailey frame 2 is provided with a positioning assembly 60, which includes a mounting plate 61 and a positioning plate 62. The positioning plate 62 is rotatably mounted on the mounting plate 61. Specifically, the positioning plate 62 is fixedly connected to a rotating shaft 63, and one end of the rotating shaft 63 is rotatably mounted on the upper surface of the mounting plate 61. The mounting plate 61 is installed between the two beams 50, and the positioning plates 62 are located on both sides of the mounting plate 61 in the length direction. The positioning plates 62 are rotated to abut against the beams 50. The Bailey frame 2 is also provided with a fixing assembly 70 for fixing the mounting plate 61. Through this structural design, the entire cast-in-place bracket is more stable during the construction process, which improves the construction efficiency and safety.

[0037] Reference Figure 4 Specifically, the crossbeam 50 includes an upper crossbeam 51, a lower crossbeam 52, and a vertical plate 53. The upper end of the vertical plate 53 is fixedly connected to the upper crossbeam 51, and the lower end of the vertical plate 53 is fixedly connected to the lower crossbeam 52. The cross-section of the crossbeam 50 is I-shaped, so the crossbeam 50 can be directly made of I-beam steel, which is simple to manufacture and has strong stability.

[0038] Reference Figure 5, the fixing component 70 includes a fixing plate 71. The fixing plate 71 is clamped between the mounting plate 61 and the cross beam 50. One mounting plate 61 corresponds to two fixing plates 71. The fixing plate 71 is provided with a fixing groove 72 for the positioning plate 62 to be clamped into. The way the fixing plate 71 is clamped makes it impossible for the mounting plate 61 to move horizontally in the left-right, front-back positions. The mounting plate 61 is stably fixed between the two cross beams 50. The fixing plate 71 can be made of steel material with good strength and high toughness to ensure that it does not deform under long-term stress. The design of the fixing groove 72 also needs to consider the size and shape of the positioning plate 62 so that the positioning plate 62 can still remain stable after being clamped in.

[0039] Referring to Figure 4 and Figure 5 , specifically, the fixing component 70 further includes a fixing rod 73. The fixing rod 73 is installed on the fixing plate 71. A fixing block 74 is installed on the fixing rod 73. The fixing block 74 abuts against the lower surface of the upper cross plate 51, so that the fixing plate 71 can no longer be disengaged upward from between the mounting plate 61 and the cross beam 50, making the fixing plate 71 more stably installed and also making the mounting plate 61 stably installed between the two cross beams 50.

[0040] A limiting block 75 is fixedly connected to the lower end of the fixing rod 73. The fixing plate 71 is provided with a limiting groove 76. The limiting block 75 slides into the limiting groove 76. After the fixing plate 71 is first installed and fixed between the mounting plate 61 and the cross beam 50, the fixing rod 73 then slides into the fixing plate 71 through the limiting block 75 to further limit the fixing plate 71. The design of the limiting groove 76 needs to consider the size and shape of the limiting block 75 so that the limiting block 75 can slide smoothly in the limiting groove 76.

[0041] Referring to Figure 6 , in addition, the fixing plate 71 is detachably installed with a connecting rod 80. The connecting rod 80 is fixedly connected with a lower pressing plate 81 for pressing against the base 4. The traditional fixing method usually uses welding or fixed riveting, which is difficult to disassemble and affects the service life of the device. The detachable structure not only improves the construction efficiency but also can adapt to the needs of different construction environments by replacing different types of connecting rods 80 and lower pressing plates 81. For example, the connecting rod 80 is fixed to the fixing plate 71 by means of threaded connection or pin connection, which is convenient for disassembly and assembly. After the base 4 is clamped on the cross beam 50, the design of the lower pressing plate 81 makes it impossible for the base 4 to leave the cross beam 50 upward, ensuring the stability of the scaffolding 3.

[0042] The implementation principle of this embodiment is as follows: By optimizing the overall structure of the prefabricated cast-in-place support, it becomes more stable and reliable during the construction process, effectively improving the construction efficiency and safety. By introducing structures such as the rotationally installed positioning plate 62 and the detachable fixing component 70, not only the problems of insufficient assembly accuracy and unstable connection are solved, but also the flexibility and adaptability of the device are improved, enabling it to better meet the requirements of different construction environments. At the same time, by reasonably selecting materials and optimizing the design, the strength and service life of the device are further improved, providing a better support solution for the construction party.

[0043] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
