[0002] Cast-in-place brackets refer to brackets used to support and fix the formwork when pouring concrete. They are one of the indispensable tools in large-scale construction projects. Especially in mountain bridge construction, if the longitudinal slope and transverse slope are relatively large, there will be a variety of bracket combinations, such as installing Bailey frames on steel columns first, with multiple Bailey frames at the same height, and then installing scaffolding on the Bailey frames. Scaffolding of different heights can be set up as needed.

[0003] The specific cast-in-place support structure is to prefabricate the steel pipe columns and Bailey frames in the factory in advance according to the drawing requirements. The length of the Bailey frames is determined according to the span of the steel pipe columns on site, and the finished Bailey frames are assembled. Then multiple beams are welded and fixed on the Bailey frames. The beams are spaced along the length of the Bailey frames. The U-shaped base is fixed at the lower end of the scaffolding poles, and the U-shaped base and the beams are clamped and fixed.

[0004] The above-mentioned related technologies are mostly assembled by on-site welding, and when disassembling, the scrap rate of the short beam is high. Summary of the invention

[0005] In order to improve the recycling rate of the assembled cast-in-place support structure, the present application provides an assembled cast-in-place support structure and a construction method thereof.

[0006] In the first aspect, the present application provides an assembled cast-in-place support structure, which adopts the following technical solution: A prefabricated cast-in-place support structure, including steel columns, Bailey frames and scaffolding, wherein the Bailey frames are also provided with a plurality of cross beams, the scaffolding is provided with a clamping seat, the clamping seat is clamped on the cross beam, the Bailey frames are detachably provided with guide rails, the length direction of the cross beam and the length direction of the guide rail are perpendicular to each other, a plurality of sliders are slidably provided on both guide rails, the guide rails are provided with more than one group, a group of the guide rails has two guide rails, a plurality of connecting rods are arranged and provided between the two guide rails, one end of the connecting rod and a slider of the guide rail are rotated The connecting rod is connected, the other end of the connecting rod is rotatably connected to the slider of another guide rail, one end of the two adjacent connecting rods is installed on the same slider, an angle is formed between the two connecting rods corresponding to one slider, the cast-in-place support structure also includes a first fixing component for fixing the connecting rod to the guide rail, the beam is rotatably installed on the slider, the slider connected by the two adjacent beams is not on the same guide rail, the slider and the beam correspond one to one, and the cast-in-place support structure also includes a second fixing component for fixing the beam to the connecting rod.

[0007] By adopting the above technical solution, multiple beams laid on the Bailey frame are connected with the clamping seats on the scaffolding to achieve stable assembly of the structure. In order to quickly and evenly install multiple beams, the beams are first installed between the two guide rails before the two guide rails are installed on the Bailey frame. The beams are installed on the sliders. The spacing between the two guide rails and the spacing between the two adjacent beams can be changed by adjusting the position of the sliders on the guide rails or the angle between the two adjacent connecting rods. When all the sliders are evenly distributed, the connecting rods are first fixed on the guide rails with the first fixing assembly, and then the beams are installed. The steps for installing the beams are: first install the beams on a guide rail in turn, first ensure that one end of the beam is rotatably connected to the slider, then lift the guide rail with the beams installed, so that all the beams can rotate downward under gravity and maintain a vertical state, all the installed beams are parallel to each other, and then fix the beams with the second fixing assembly; then install all the beams on the other guide rail, and use the same method to make the beams parallel to each other, and then fix all the beams on the other guide rail with the second fixing assembly, so that all the beams are fixed and installed at equal distances, and finally install the guide rail on the Bailey frame to complete the installation of all beams. If the entire support structure needs to be disassembled, the guide rail can be removed from the Bailey frame, and the connecting rod between the two guide rails can adjust the angle according to the on-site construction conditions to increase the flexibility of the support structure, so that the beams can be reused, thereby improving the recycling rate of the assembled cast-in-place support structure.

[0008] Optionally, the first fixing assembly includes a fixing rod and a fixing plate, the fixing rod and the connecting rod corresponding one to one, the fixing rod is fixedly installed at the middle position of the connecting rod, a long groove is opened on the fixing plate, the long groove extends along the length direction of the fixing plate, and the fixing rod is inserted into the long groove.

[0009] By adopting the above technical solution, since the connecting rod is rotatably installed on the slider, the connecting rod needs to be rotated when adjusting the connecting rod angle. The connecting rod is limited in rotation by the cooperation of the fixing rod and the fixing plate, so that multiple connecting rods can maintain a fixed spacing. This fixing method is simple and easy. At the same time, the long groove design also increases the flexibility of fixing, which is convenient for adjusting the position of the connecting rod.

[0010] Optionally, both ends of the fixing plate are fixedly connected to the guide rail.

[0011] By adopting the above technical solution, the fixing plate is fixed on the guide rail, so that the sliding block cannot slide on the guide rail, thereby further fixing the sliding block.

[0012] Optionally, a group of the second fixing components corresponds to one of the beams, and the second fixing components include a moving block and a fixing screw, the moving block is slidably installed in the long groove, and the fixing screw passes through the beam and is threadedly connected to the moving block.

[0013] By adopting the above technical solution, the moving block slides on the fixed plate, and the fixing screw passes through the beam and is threadedly connected to the moving block, thereby fixing the beam; this fixing method is not only easy to operate, but also can be flexibly adjusted according to the position of the beam to ensure stable fixation of the beam.

[0014] Optionally, the guide rail includes a plurality of splicing sections that are spliced ​​and fixed to each other.

[0015] By adopting the above technical solution, the guide rail is composed of multiple spliced ​​and fixed sections, which is convenient for adjusting the length according to construction requirements; this design improves the flexibility and adjustability of the guide rail, making the entire support structure more adaptable to different construction environments.

[0016] Optionally, a support block is slidably mounted on the guide rail, the support block extends out of the guide rail, and one end of the crossbeam away from the sliding block abuts against the support block.

[0017] By adopting the above technical solution, the support block slidably installed on the guide rail extends out of the guide rail, and the end of the beam away from the slider abuts against the support block, providing additional support for the beam; this design enhances the stability of the beam and improves the bearing capacity of the entire bracket structure.

[0018] Optionally, a mounting shaft is mounted on the slider, and the connecting rod and the crossbeam are rotatably connected via the same mounting shaft and the slider.

[0019] By adopting the above technical solution, the mounting shaft installed on the slider enables both the connecting rod and the cross beam to be rotatably connected to the slider through the same mounting shaft, thereby realizing flexible rotation of the connecting rod and the cross beam; this connection method simplifies the structure, improves construction efficiency, and at the same time enables the connecting rod and the cross beam to be flexibly adjusted according to construction requirements.

[0020] In a second aspect, the present application provides a construction method for an assembled cast-in-place support structure, which adopts the following technical solution: A construction method of an assembled cast-in-place support structure, using the above-mentioned assembled cast-in-place support structure for construction, comprises the following steps: S1. Install steel columns and Bailey frames according to the specified size and position; S2. First slide the slider into the guide rail, arrange the sliders according to the size interval, and then continue to install the connecting rods on the sliders to form an angle between the two adjacent connecting rods; S3, determine the position of the slider and the angles of the two adjacent connecting rods are consistent, and then use the first fixing component to fix the connecting rod; S4. First, install some beams on a guide rail, lift the guide rail to make multiple beams rotate and droop, and the beams are parallel to each other; S5. Use a second fixing assembly to fix the crossbeam on the connecting rod; S6. Install some beams on another guide rail, lift the guide rail to make the beams rotate and droop, and the beams are parallel to each other; S7, using a second fixing assembly to fix the crossbeam on the connecting rod; After S8 and the crossbeam are installed, install the rails on the Bailey frame; S9. Connect the scaffolding connector to the beam.

[0021] By adopting the above technical scheme, the operation of installing the beams on the guide rails can be carried out on the ground. When multiple beams are all installed on the guide rails, the guide rails can uniformly adjust the positions of the multiple beams so that the multiple beams are parallel to each other and can be fixed. After the beams on the two guide rails are installed, the guide rails are hoisted to the Bailey frame for installation, so that multiple beams are evenly arranged and installed on the Bailey frame. The installation method of the beams is safe, simple and fast. When the bracket needs to be disassembled, the guide rails are disassembled from the Bailey frame after the scaffolding is disassembled, and multiple beams can be removed together. According to the matching relationship between the slider and the connecting rod and the guide rail, the spacing between the beams can also be adjusted according to the construction situation, which can not only improve the recycling rate of each component of the bracket, but also increase the installation flexibility of the entire bracket.

[0022] In summary, the present application includes at least one of the following beneficial effects: 1. Through the coordinated use of Bailey frames, guide rails, sliders, connecting rods and other components, the entire support structure has extremely high flexibility and adjustability, and can be quickly adjusted according to different construction requirements, thereby improving the recycling rate of the assembled cast-in-place support structure; 2. Through the design of the first fixing assembly, the second fixing assembly, the support block and other components, the stability and bearing capacity of the entire support structure are enhanced, and the safety during the construction process is improved.

[0025] The following is combined with Figure 1-7 This application is described in further detail.

[0026] The present application embodiment discloses an assembled cast-in-place support structure. Figure 1 , an assembled cast-in-place support structure includes a steel column 1, a Bailey frame 2 and a scaffold 3. The steel column 1, Bailey frame 2 and scaffold 3 are all standard parts. The length of the steel column 1 is generally set at 3 meters, 4 meters and 6 meters. During construction, steel columns 1 of different specifications are used for erection according to the actual situation on site. Each section of the steel column 1 has flanges at both ends. The upper and lower steel columns 1 are connected with high-strength bolts. The top steel column 1 needs to be connected with a double-jointed I-beam 4. The length of the Bailey frame 2 is determined according to the span of the steel column 1 on site, and the Bailey frame 2 is assembled into a Bailey beam of appropriate length through bolts and nuts. Finally, the scaffold 3 is installed on the Bailey frame 2. Reference Figure 2 In order to ensure that the scaffold 3 can be accurately installed on the Bailey frame 2 with a suitable spacing, a plurality of beams 4 are also laid on the Bailey frame 2. A clamping seat 31 is fixedly installed on the vertical pole of the scaffold 3, and the cross section of the clamping seat 31 is a U-shaped structure, and the clamping seat 31 is clamped on the beam 4.

[0027] Reference Figure 3 and Figure 4 The Bailey frame 2 is detachably mounted with a guide rail 5, which includes a plurality of mutually spliced ​​sections, and a connecting plate 52 is fixedly mounted on the spliced ​​sections. The connecting plates 52 of two adjacent spliced ​​sections are fixedly connected by bolts and nuts. The side walls of the guide rail 5 are also spaced apart with mounting plates 53, and the Bailey frame 2 is also fixedly welded with mounting plates 53. The mounting plates 53 between the guide rail 5 and the Bailey frame 2 fit each other, and the two mounting plates 53 are penetrated by bolts, and the bolts are threadedly connected with nuts.

[0028] Reference Figure 5, the guide rail 5 is provided with a guide groove 51, and the cross section of the guide groove 51 is a T-shaped structure. The guide rail 5 is slidably installed with a slider 6 in the guide groove 51, and the cross section of the slider 6 is adapted to the guide groove 51. The embodiment of the present application has two groups of guide rails 5, one group of guide rails 5 has two guide rails 5, and one group of guide rails 5 is provided with two guide rails, which are respectively installed on different Bailey frames 2, and the two guide rails 5 are parallel to each other. A plurality of connecting rods 7 are arranged and installed between the two guide rails 5, and the slider 6 is fixedly installed with a mounting shaft 61, and the mounting shaft 61 extends out of the guide rail 5. One end of the connecting rod 7 is connected to the slider 6 of one guide rail 5, and the mounting shaft 61 of the slider 6 passes through the connecting rod 7, and the connecting rod 7 and the mounting shaft 61 are rotatably connected; the other end of the connecting rod 7 is connected to the slider 6 of the other guide rail 5, and the mounting shaft 61 of the other slider 6 also passes through the connecting rod 7, and the connecting rod 7 and the mounting shaft 61 are rotatably connected. One end of two adjacent connecting rods 7 is installed on the same slider 6, and the two connecting rods 7 on one slider 6 are in contact up and down and form an angle. When adjusting the angle between the two connecting rods 7, the two guide rails 5 cannot be fixed on the Bailey frame 2, because the angle between the two connecting rods 7 is different and the spacing between the two guide rails 5 is also different. When the angle between the two connecting rods 7 is determined, the cast-in-place support structure also includes a first fixing assembly 8 for fixing all the connecting rods 7 on the guide rails 5, and the first fixing assembly 8 keeps all the sliders 6 immobile.

[0029] Reference Figure 6 The first fixing assembly 8 includes a fixing rod 81 and a fixing plate 82. The fixing rod 81 corresponds to the connecting rod 7 one by one. The fixing rod 81 is fixedly installed on a plane in the middle of the connecting rod 7. The fixing plate 82 is provided with a long slot 83, and the long slot 83 extends along the length of the fixing plate 82. The lengths of the fixing rods 81 of two adjacent connecting rods 7 are different, but the ends of the fixing rods 81 away from the connecting rod 7 are all on the same plane, so that the ends of the fixing rods 81 away from the connecting rod 7 can be inserted into the long slot 83. The fixing rod 81 is fixedly installed first when the connecting rod 7 is manufactured, reducing the number of on-site installation steps. Since the connecting rod 7 can also rotate with the installation shaft 61 as the rotation center when the slider 6 moves, when the fixing rod 81 is inserted into the fixing plate 82, the connecting rod 7 can no longer rotate.

[0030] The two ends of the fixed plate 82 are connected with reinforcing rods 84, and one end of the reinforcing rod 84 is fixedly mounted on the guide rail 5 by bolts, so that the slider 6 cannot continue to slide along the guide rail 5. Since the spacing between the two guide rails 5 can be changed, the reinforcing rod 84 and the side wall of the fixed plate 82 can also be detachably connected, for example, by bolting, so as to replace the reinforcing rods 84 of different lengths.

[0031] Reference Figure 7After the slider 6 is fixed on the guide rail 5, the crossbeam 4 is installed on the slider 6. A through hole is opened on the crossbeam 4, and the installation shaft 61 passes through the through hole. The crossbeam 4 is rotatably installed on the installation shaft 61, and the inner wall of the through hole of the crossbeam 4 and the installation shaft 61 fit each other. The crossbeam 4 and the slider 6 correspond one to one, and two adjacent crossbeams 4 are respectively connected to the installation shafts 61 of different guide rails 5. When installing the crossbeam 4, the crossbeam 4 is first installed on the installation shaft 61 of a guide rail 5 in sequence. In order to enable the crossbeam 4 to rotate around the installation shaft 61 and not to be separated from the installation shaft 61, the installation shaft 61 is threadedly connected to the limit nut 62. One end of the crossbeam 4 only rotates on the installation shaft 61, and the other end of the crossbeam 4 has no restrictions. When the crossbeams 4 on a guide rail 5 are all installed, the guide rail 5 is lifted so that all the crossbeams 4 are rotated downward under the action of gravity, so that the two adjacent crossbeams 4 form a parallel relationship. The cast-in-place bracket structure also includes a second fixing component 9 for fixing the crossbeams so that they are no longer free to rotate.

[0032] Reference Figure 7 , a group of second fixed components 9 corresponds to one cross beam 4, and the second fixed component 9 includes a moving block 91 and a fixed screw 92. The moving block 91 is slidably installed on the long groove 83 of the fixed plate 82, and the fixed screw 92 penetrates the cross beam 4 and is threadedly connected with the moving block 91. The cross section of the long groove 83 is also a T-shaped structure, and the cross section of the moving block 91 is also a T-shaped structure, so that the moving block 91 is not easy to separate from the fixed plate 82 when sliding in the long groove 83. When the cross beams 4 on a guide rail 5 are parallel to each other, the moving block 91 slides to fit the lower surface of the cross beam 4, and then the fixed screw 92 penetrates the cross beam 4 and is threadedly connected with the moving block 91, which plays a role in fixing the cross beam 4. A waist-shaped through groove for the fixed screw 92 to pass through is provided on the cross beam 4, so that when the distance between the two guide rails 5 changes, the fixed screw 92 can also smoothly penetrate the cross beam 4 and be threadedly connected with the moving block 91.

[0033] Reference Figure 7 A support block 20 is also slidably mounted on the guide rail 5. The support block 20 extends out of the guide rail 5, and the end of the cross beam 4 away from the slider 6 abuts against the support block 20. The support block 20 supports the cross beam 4, so that the cross beam 4 can be more stably fixedly connected to the scaffold 3. In order to further fix the cross beam 4, a waist-shaped groove can also be opened on the cross beam 4, and the support block 20 is threadedly connected with a reinforcing bolt 21. When the cross beam 4 and the moving block 91 are fixedly connected, the moving support block 20 fits on the lower surface of the cross beam 4, and the reinforcing bolt 21 penetrates the cross beam 4 and the support block 20 and is threadedly connected, so that the cross beam 4 and the guide rail 5 form a further connection relationship.

[0034] The implementation principle of an assembled cast-in-place support structure in the embodiment of the present application is: After the steel column 1 and the Bailey frame 2 are installed according to the specified size and position at the construction site, the connecting rod 7 is first installed on the guide rail 5 on the ground. The specific steps are to first slide the slider 6 into the guide rail 5, arrange the slider 6 according to the size interval, and then continue to install the connecting rod 7 on the slider 6 to form an angle between two adjacent connecting rods 7; determine that the position of the slider 6 and the angle between two adjacent connecting rods 7 are consistent, and the fixed rod 81 is located on the same straight line because the arrangement of the connecting rod 7 is all located on the same straight line, and then match the fixing plate 82 with the fixing rod 81, insert one end of the fixing rod 81 into the long groove 83, and then fix the two ends of the fixing plate 82 on the guide rail 5, so that the connecting rod 7 and the slider 6 are fixedly installed on the guide rail 5. Then install all the cross beams 4 on one guide rail 5 first, lift the guide rail 5 to make multiple cross beams 4 automatically rotate and droop, and form a state parallel to each other among the multiple cross beams 4, slide the movable block 91, and the fixing bolts fix the cross beams 4, and the sliding support block 20 can also support the cross beams 4, and then use the reinforcing screws to further fix the cross beams 4; continue to install the cross beams 4 on another guide rail 5 in turn, continue to lift the guide rail 5 to make multiple cross beams 4 rotate and droop, so that the cross beams 4 of the other guide rail 5 are parallel to each other; use the second fixing component 9 to fix the cross beam 4 on the connecting rod 7; after all the cross beams 4 are installed, install the guide rail 5 on the Bailey frame 2, and finally set up the scaffolding 3, and clamp the clamping seat 31 of the scaffolding 3 on the cross beam 4.

[0035] The embodiment of the present application also discloses a construction method of an assembled cast-in-place support structure.
