Description

Technical Field

[0002] The cantilevers on both sides of the box beam have a certain length, and the bottom of the cantilever is arc-shaped. Before pouring, a flange plate needs to be set at the bottom of the cantilever, and a back rib is set below the flange plate. To ensure the stability of the back rib, a support member needs to be installed between the back rib and the cross beam. At present, in the process of back rib support, the support rod is tilted at different angles between the back rib and the cross beam, and the support rod and the lock are installed separately, which is not only inconvenient to adjust the angle, but also difficult to assemble, which affects the installation speed and has low practicality.

DETAILED DESCRIPTION

[0022] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0023] like Figure 1-Figure 4As shown, the present embodiment provides a multi-angle adjustable auxiliary stabilization device for a cast-in-place box girder, comprising a bidirectional inner screw tube 1, support screws 2 are threadedly installed at both ends of the inner part of the bidirectional inner screw tube 1, a support plate 3 is provided at the end of the support screw 2 away from the bidirectional inner screw tube 1, ear plates 4 are symmetrically provided on the side of the support plate 3 close to the support screw 2, a positioning shaft 5 passing through the support screw 2 is fixed between the two groups of ear plates 4, a through groove 6 matching the positioning shaft 5 is provided at the end of the support screw 2, the length of the through groove 6 is greater than the diameter of the positioning shaft 5, a cone block 9 is fixed at the end of the support screw 2 close to the support plate 3, anti-slip teeth 10 are evenly provided on the top of the support plate 3 along the width direction, and the anti-slip teeth 10 are aligned with the end of the support screw 2, and a fastening mechanism 11 is provided on the side of the support plate 3 away from the bidirectional inner screw tube 1.

[0024] Overall working principle: When in use, place the device between the crossbeam and the back rib, then first fit the bottom support plate 3 onto the crossbeam, and use the fastening mechanism 11 to fix the position of the support plate 3, adjust the support angle of the device, and then rotate the two-way inner screw tube 1 to fit the support plate 3 at the top of the device onto the back rib, and then use the fastening mechanism 11 to fix the top support plate 3. After both sets of support plates 3 are fixed, rotate the two-way inner screw tube 1 again to extend the support screw 2 to the maximum extension distance. At this time, the cone block 9 at the end of the support screw 2 will be inserted into the anti-slip tooth 10 to stabilize the support angle of the device, and the device installation is complete.

[0025] In this embodiment, springs 7 are installed at the inner top of the through slots 6, and pressure plates 8 are fixed at the ends of the springs 7. The pressure plates 8 are slidably arranged inside the through slots 6, and the bottom ends of the pressure plates 8 are in contact with the positioning shaft 5.

[0026] Local working principle: Since the spring 7 and the pressure plate 8 are both located inside the through slot 6, when the support screw 2 is not subjected to extrusion force, the positioning shaft 5 can be ensured to contact the end of the through slot 6, ensuring relative stability and making the angle adjustment of the device more convenient.

[0027] In this embodiment, anti-skid patterns are evenly arranged at the middle position of the outer side of the bidirectional inner spiral tube 1 along the circumferential direction, and the anti-skid patterns are along the length direction of the bidirectional inner spiral tube 1 .

[0028] Partial working principle: When the control device is extended or retracted, the anti-slip grooves on the outer side of the bidirectional inner screw tube 1 increase the friction between the tool and the control device, making the rotation more convenient.

[0029] In this embodiment, a second bidirectional internal screw 18 is fixed along the length direction at the middle position inside the bidirectional internal screw tube 1 , and both ends of the support screw 2 are provided with a thread groove 19 that cooperates with the second bidirectional internal screw 18 .

[0030] Partial working principle: When the device is telescopically adjusted, both the inside and the outside of the support screw 2 are supported, ensuring the support stability of the device.

[0031] In this embodiment, the fastening mechanism 11 includes a guide groove 12, a slider 13, a first bidirectional screw 14 and a trapezoidal block 15. The guide groove 12 is symmetrically arranged at both ends of the support plate 3 away from the bidirectional inner screw tube 1. The slider 13 is slidably installed inside the guide groove 12, and the first bidirectional screw 14 is rotatably installed between the two ends inside the support plate 3. The two ends of the first bidirectional screw 14 are respectively threadedly connected to the slider 13, and the two ends of the first bidirectional screw 14 extend to the outside of the support plate 3. The bottom end of the slider 13 is fixed with a trapezoidal block 15. The two groups of trapezoidal blocks 15 are symmetrical to each other, and the inclined surfaces of the trapezoidal blocks 15 are opposite.

[0032] Local working principle: Since the cross beams and back ribs are mostly I-shaped steel, after the support plate 3 is fitted with the surface of the I-shaped steel, the first bidirectional screw 14 is rotated to control the trapezoidal blocks 15 on the two sets of sliders 13 to move toward each other. The two sets of trapezoidal blocks 15 are clamped on the sides of the I-shaped steel for extrusion and fixation, making installation more convenient.

[0033] In this embodiment, a bottom plate 16 is fixed to the bottom end of the inner side of the trapezoidal block 15 , and a reinforcing screw 17 is threadedly installed at the bottom end of the bottom plate 16 .

[0034] Partial working principle: After the trapezoidal block 15 is tightly attached to both sides of the I-shaped steel, the reinforcing screws 17 are tightened. The reinforcing screws 17 can increase the fit between the surface of the I-shaped steel and the support plate 3 and increase stability.

[0035] In this embodiment, adjustment blocks are fixed to both ends of the first bidirectional screw rod 14 , and anti-slip grooves are provided on the surfaces of the adjustment blocks.

[0036] Partial working principle: in the process of controlling the rotation of the first bidirectional screw 14, the adjustment block has a larger surface area, which can facilitate tool clamping and make adjustment more convenient.

[0037] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
