Description

Technical Field

[0001] This utility model belongs to the field of building construction equipment, and specifically relates to a fixed support device between columns of a prefabricated portal pipe gallery. Background Technology

[0002] In the hoisting construction of precast concrete portal frame utility tunnels, the hoisting points are located at the top of the columns or on the connecting beams. After the components are hoisted, the base of the portal frame utility tunnel is subjected to inward stress due to gravity. If the designed structural beams are small, there is a risk of deformation at the ends of the concrete beams and at the base of the columns. In this case, temporary supports need to be added inside the columns of the portal frame utility tunnel to prevent inward stress. The traditional method is to embed embedded parts inside the columns before the utility tunnel is precast, and then weld steel sections as temporary supports between the columns. This method requires more materials, has a longer preparation time, involves a large amount of welding, and the materials are basically invested in one go, resulting in low overall construction efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model aims to provide a fixed support device between precast portal frame columns. This device can effectively fix and support the two concrete columns of the portal frame, preventing deformation of the precast components. This device is reusable and can be adapted to support concrete columns of different thicknesses. It is simple and convenient to install, effectively improving work efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A fixed support device between columns of a prefabricated portal frame pipe gallery includes a horizontal brace and two fixing members. The two fixing members are symmetrically fixed to the corresponding concrete columns of the pipe gallery, and the horizontal brace is horizontally fixed between the two fixing members. The fixing members include U-shaped clips with downward openings that are clamped onto the concrete columns. The inner side of the opening of the U-shaped clips is clamped to the two side walls of the concrete columns, and the opening spacing of the U-shaped clips is adjustable. The horizontal brace includes a sleeve and two threaded rods with opposite threads. The two threaded rods are coaxially threaded onto both ends of the sleeve, and the ends of the two threaded rods are fixed to the side walls of the corresponding U-shaped clips through corresponding connecting seats. Tightening parts are fixedly provided on both ends of the sleeve.

[0006] Preferably, the U-shaped clamp includes a first clamping plate and a second clamping plate that vertically clamp both sides of the concrete column. The upper end of the first clamping plate is horizontally fixed to one end of the first horizontal plate, and the upper end of the second clamping plate is horizontally fixed to the end of the second clamping plate. The other end of the first horizontal plate is horizontally slidably fitted into a sliding cavity opened in the second horizontal plate. An adjustment component for adjusting the movement of the first horizontal plate is also installed in the second horizontal plate.

[0007] Preferably, the adjusting assembly includes a handwheel, a rotating rod, and a lead screw. A mounting cavity is also provided within the second horizontal plate above the sliding cavity. The lead screw is horizontally mounted within the mounting cavity, and a first bevel gear is coaxially mounted at the end of the lead screw. The handwheel is horizontally rotatably mounted on the top of the second horizontal plate. The rotating rod is coaxially fixed to the shaft of the handwheel. The lower end of the rotating rod extends vertically into the mounting cavity and is coaxially mounted on the second bevel gear. The second bevel gear meshes perpendicularly with the first bevel gear. A connecting groove is provided at the bottom of the mounting cavity, communicating with the sliding cavity. A connecting block is fixedly connected to the right end of the first horizontal plate. The connecting block extends upwards through the mounting cavity and is threaded onto the lead screw.

[0008] Preferably, the end of the threaded rod is fixed to the connecting seat, which is vertically slidably mounted on the opposite sidewalls of the two U-shaped clips and fixed by a locking member.

[0009] Preferably, the U-shaped clip has a vertically sliding groove on its side wall, and the connecting seat is slidably engaged in the groove; the locking member includes a locking bolt, which is horizontally installed on the connecting seat, and the end of the locking bolt abuts against the side wall of the U-shaped clip.

[0010] Preferably, the groove is a T-shaped groove, and a T-shaped slider that mates with the T-shaped groove is provided on the end face of the connecting seat. The T-shaped slider is slidably engaged in the T-shaped groove.

[0011] Preferably, a handle is installed on the top of the U-shaped clip.

[0012] Preferably, a gasket is fixed inside the opening of the U-shaped clip.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This application utilizes the action of the adjustment component to drive the first horizontal plate to move left and right in the sliding cavity of the second horizontal plate, thereby adjusting the distance between the first clamping plate and the second clamping plate, so that the opening distance of the U-shaped clamp can be changed, thereby enabling the device to be adapted to the installation and use of concrete columns of different thicknesses in the pipe gallery.

[0015] 2. When the sleeve is rotated by the screwing part, the threaded rod with reversed threads at both ends can be extended or contracted synchronously in the sleeve, thereby effectively adjusting the overall length of the cross brace. This allows the device to be used for supporting and fixing different spacings of pipe gallery columns.

[0016] 3. This application utilizes the T-shaped slider on the connecting seat and the sliding groove on the second clamp to slide and adjust the position of the connecting seat on the U-shaped clamp, and uses locking bolts to lock the connecting seat, thereby adjusting the height of the cross brace between the two U-shaped clamps to fix the support according to actual construction needs.

[0017] 4. The gasket in this application can avoid rigid contact between the U-shaped clip and the concrete column, preventing premature damage to the surface of the concrete column during support and fixing. Attached Figure Description

[0020] Figure 3 This is a schematic diagram of the installation of the first and second horizontal plates of this utility model. Detailed Implementation

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0022] like Figure 1-3 As shown, this utility model proposes a fixed support device between columns of a prefabricated portal frame pipe gallery, including a horizontal brace and two fixing members. The two fixing members are symmetrically fixed on two corresponding concrete columns 3 of the pipe gallery, and the horizontal brace is horizontally fixed between the two fixing members. The fixing members include U-shaped clips 1 with downward openings that are engaged with the concrete columns 3. The inner side of the opening of the U-shaped clips 1 is clamped to the two side walls of the concrete columns 3, and the opening spacing of the U-shaped clips 1 is adjustable.

[0023] Specifically, each U-shaped clamp 1 includes a first clamping plate 111 and a second clamping plate 121 that vertically clamp the two sides of the concrete column 3 respectively. The upper end of the first clamping plate 111 is horizontally fixed to one end of the first horizontal plate 112, and the upper end of the second clamping plate 121 is horizontally fixed to one end of the second clamping plate 121. The other end of the first horizontal plate 112 is horizontally slidably sleeved in a sliding cavity 1222 opened in the second horizontal plate 122. An adjustment component for adjusting the movement of the first horizontal plate 112 is also installed in the second horizontal plate 122. The adjustment assembly includes a handwheel 21, a rotating rod 23, and a lead screw 22. A mounting cavity 1221 is also provided within the second horizontal plate 122 above the sliding cavity 1222. The lead screw 22 is horizontally mounted within the mounting cavity 1221, and a first bevel gear 25 is coaxially mounted at the end of the lead screw 22. The handwheel 21 is horizontally rotatably mounted on the top of the second horizontal plate 122. The rotating rod 23 is coaxially fixed to the shaft of the handwheel 21. The lower end of the rotating rod 23 extends vertically into the mounting cavity 1221 and is coaxially mounted on the second bevel gear 24. The second bevel gear 24 meshes perpendicularly with the first bevel gear 25. A connecting groove is provided at the bottom of the mounting cavity 1221, which communicates with the sliding cavity 1222. A connecting block 1121 is fixedly connected to the right end of the first horizontal plate 112. The connecting block 1121 extends upward through the mounting cavity 1221 and is threaded onto the lead screw 22.

[0024] This application utilizes the movement of the adjustment component to drive the first horizontal plate 112 to move left and right in the sliding cavity 1222 of the second horizontal plate 122, thereby adjusting the distance between the first clamping plate 111 and the second clamping plate 121, so that the opening distance of the U-shaped clip 1 can be changed, thereby enabling the device to adapt to the installation and use of concrete columns 3 of different thicknesses in the pipe gallery.

[0025] When the U-shaped clip 1 is installed and adjusted, the handwheel 21 at the top of the U-shaped clip 1 is rotated to drive the rotating rod 23 and the second bevel gear to rotate. The meshing of the two bevel gears drives the lead screw 22 to rotate, and then the connecting block 1121 drives the first horizontal plate 112 to slide in the sliding cavity 1222 of the second horizontal plate 122, which allows the first horizontal plate 112 to retract, thereby effectively adjusting the distance between the lower first clamping plate 111 and the second clamping plate 121. The opening adjustment of the U-shaped clip 1 of this device is very simple and convenient.

[0026] The cross brace includes two threaded rods 51 and a sleeve 52. The two threaded rods 51 are coaxially threaded onto both ends of the sleeve 52, and the ends of the two threaded rods 51 are fixed to the side walls of the corresponding U-shaped clamps 1 via corresponding connecting seats 4. The threads of the two threaded rods 51 are arranged in opposite directions, so that the rotation of the sleeve 52 can drive the two threaded rods 51 to retract or extend synchronously. Tightening parts 521 are fixed to both ends of the sleeve 52. The tightening parts 521 can be nut structures fixed to the outside of the sleeve 52, facilitating the rotational adjustment of the sleeve 52.

[0027] When the sleeve 52 is rotated by the screwing part 521, the threaded rod 51 with reversed threads at both ends can be extended or contracted synchronously in the sleeve 52, thereby effectively adjusting the overall length of the cross brace. This allows the device to be used for supporting and fixing different spacings of pipe gallery columns.

[0028] Specifically, the end of the threaded rod 51 is fixed to the connecting seat 4, which is vertically slidably mounted on the opposite side walls of the two U-shaped clips 1 (i.e., the outer side wall of the second clamping plate 121) and fixed by a locking member. The U-shaped clips 1 have vertically slidable grooves 10 on their side walls, and the connecting seat 4 is slidably engaged in these grooves. The locking member includes a locking bolt 41, which is horizontally mounted on the connecting seat 4, with its end abutting against the side wall of the U-shaped clips 1. The groove 10 is a T-shaped groove, and the end face of the connecting seat 4 has a T-shaped slider (not shown in the figure) that mates with the T-shaped groove, which is slidably engaged in the T-shaped groove.

[0029] This application utilizes the T-shaped slider on the connecting seat 4 to slide with the groove 10 on the second clamping plate 121 to adjust the position of the connecting seat 4 on the U-shaped clamp 1, and uses the locking bolt 41 to lock the connecting seat 4. Thus, the height of the cross brace abutting and fixing support between the two U-shaped clamps 1 can be adjusted according to the actual construction needs.

[0030] The top of the U-shaped clip 1 is equipped with a handle 13, which makes it easier to move the U-shaped clip 1. In addition, a gasket is fixed inside the opening of the U-shaped clip 1. The gasket can avoid rigid contact between the U-shaped clip 1 and the concrete column 3, and prevent damage to the surface of the concrete column 3 during support and fixation.

[0031] When using this utility model, firstly, place the two U-shaped clips 1 with their openings facing downwards onto the corresponding concrete columns 3 on both sides of the pipe gallery. Adjust the height of the connecting seat 4 on the U-shaped clips 1 and then fix it with the locking bolt 41. Next, screw the adjusting sleeve to extend the threaded rods 51 at both ends outwards, thereby effectively abutting the second clamping plate 121 of the U-shaped clips 1 against the concrete column 3. Then, rotate the handwheel 21 on the two U-shaped clips 1 to bring the first clamping plate 111 close to the side wall of the concrete column 3, so that the two clamping plates can be effectively clamped on both sides of the concrete column 3, thereby completing the clamping and fixing of the U-shaped clips 1, ensuring that the two columns of the pipe gallery maintain stable force and ensuring the quality of the components.
