Description
Technical Field
[0001] This utility model belongs to the field of road and bridge construction, and more specifically, it relates to a bracket device. Background Technology
[0002] A bridge construction support bracket is a steel frame device used for temporary support of bridge structures. It is mainly used between bridge piers and beams. The bracket transfers the load of the beam to the pier to ensure the stability and safety of the construction area. Currently, traditional road and bridge construction brackets consist of diagonal bracing steel rods, load-bearing beams, and embedded parts. The diagonal bracing steel rods and load-bearing beams are installed on the bridge surface through the embedded parts. The diagonal bracing steel rods obliquely support the load-bearing beams, forming a fixed triangular support structure with the diagonal bracing steel rods, load-bearing beams, and piers. A distribution beam is erected on the upper side of the load-bearing beam for support. Since the support range of different bridge beams varies, the length range and support angle of the load-bearing beams protruding from the piers are also different. However, the length of the traditional load-bearing beams is fixed and the triangular structure is rigid. For different beam construction support requirements, brackets with corresponding structures need to be prefabricated and welded in advance. It can be seen that the length of the load-bearing beams and the support inclination angle of traditional road and bridge construction brackets cannot be flexibly adjusted according to the requirements of the beam construction support structure. As a result, the structure of the road and bridge construction brackets cannot meet the beam support construction needs of different bridges, and the bracket structure has poor versatility.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figures 1-7 As shown, this utility model provides a bracket device, including a support plate 4; a vertical frame 5 is bolted to the upper side of the support plate 4, and an embedded part 1 is bolted to the rear side of the support plate 4; it also includes a telescopic load-bearing beam 7; a support 10 is welded to the front side of the vertical frame 5, and the embedded part 1 is bolted to the rear side of the vertical frame 5; a fixed load-bearing beam 8 is hinged to the top of the vertical frame 5; a supporting diagonal rod 9 is hinged to the left and right sides of the fixed load-bearing beam 8; the supporting diagonal rod 9 has a through hole extending from left to right; the through hole of the supporting diagonal rod 9... A locking bolt 12 is inserted inside, and a locking nut 13 is engaged on the threaded surface of the outer side of the locking bolt 12. A support plate 15 is welded to the inner side of the support frame 5. A motor 14 is installed on the upper side of the support plate 15. A threaded adjusting rod 2 is installed on the motor shaft of the motor 14. The bottom end of the threaded adjusting rod 2 is rotatably connected to the support frame 5. A control machine 16 is installed on the inner side of the support frame 5. The control machine 16 is connected to the motor 14 through a wire. A push-pull rod 6 is hinged to the lower side of the telescopic load-bearing beam 7. A slider 3 is hinged to the bottom end of the push-pull rod 6.
[0022] In this embodiment, the fixed load-bearing beam 8 is a rectangular cylindrical structure with an open front end. The telescopic load-bearing beam 7 is embedded inside the cylindrical structure of the fixed load-bearing beam 8. The telescopic load-bearing beam 7 moves directionally along the fixed load-bearing beam 8 to change the protruding length of the bracket load-bearing beam. The left and right sides of the fixed load-bearing beam 8 are provided with long through grooves, and fastening bolts 11 are inserted into the long through grooves of the fixed load-bearing beam 8.
[0023] In this embodiment, threaded holes are provided on both the left and right sides of the telescopic load-bearing beam 7. Fastening bolts 11 are engaged in the threaded holes of the telescopic load-bearing beam 7. The threaded holes of the telescopic load-bearing beam 7 are opposite to the elongated through-slot of the fixed load-bearing beam 8. During the tightening process of the fastening bolts 11 in the threaded through-holes of the telescopic load-bearing beam 7, the nuts of the fastening bolts 11 are tightly fitted to the outside of the elongated through-slot of the fixed load-bearing beam 8, so that the fastening bolts 11 clamp and fix the telescopic load-bearing beam 7 and the fixed load-bearing beam 8, ensuring that the adjusted lengths of the telescopic load-bearing beam 7 and the fixed load-bearing beam 8 remain fixed, thereby improving the stability of the structure of the telescopic load-bearing beam 7 and the fixed load-bearing beam 8.
[0024] In this embodiment, the embedded part 1 is an I-shaped structure, and the rear end of the I-shaped structure of the embedded part 1 is a hook-shaped structure. The hook-shaped structure of the embedded part 1 is embedded in the concrete pier, thereby increasing the holding force of the embedded part 1 inside the concrete pier and improving the support connection strength of the bracket on the concrete pier.
[0025] In this embodiment, the support frame 5 is a groove-shaped structure with an opening on the front side. Eight sets of through holes are arranged equidistantly from top to bottom on the left and right sides of the support frame 5. The through holes of the support rod 9 are connected to the through holes of the support frame 5. The locking bolt 12 is inserted into the through holes of the support frame 5. The locking bolt 12, together with the locking nut 13, clamps and locks the through holes of the support rod 9 at different height positions of the support frame 5. The support rod 9 supports the fixed load-bearing beam 8 hinged at the top to be rotated and adjusted to different pitch angle positions, so that the bracket is suitable for the support angle requirements of different beams.
[0026] In this embodiment, the upper side of the slider 3 is provided with a threaded through hole that runs vertically through the top and bottom. The outer side of the threaded adjusting rod 2 is threadedly engaged in the threaded through hole of the slider 3. When the motor 14 drives the threaded adjusting rod 2 to rotate, the threaded adjusting rod 2 drives the slider 3, which is engaged in the threaded through hole, to slide vertically up and down along the rear side wall of the groove of the support frame 5. The slider 3 pushes the telescopic load-bearing beam 7 to slide directionally along the fixed load-bearing beam 8 through the push-pull rod 6 hinged to the front side, thereby completing the rapid adjustment of the combined extension length of the telescopic load-bearing beam 7 and the fixed load-bearing beam 8 to meet the temporary support requirements of different beams.
[0027] The specific usage and function of this embodiment are as follows:
[0028] In adjusting the support length and angle of the beam by the bracket, this invention first aligns the through holes of the two sets of support diagonal rods 9 with the corresponding heights of the eight sets of through holes on the left and right sides of the upright 5, according to the support angle of the beam. Then, locking bolts 12 are inserted from left to right into the through holes of the support diagonal rods 9 and the through holes of the upright 5. Next, locking nuts 13 are screwed onto the threaded structure on the outer side of the locking bolts 12. The locking nuts 13 and locking bolts 12 lock the support diagonal rods 9 within the through holes of the upright 5. The support diagonal rods 9 provide oblique support to the fixed load-bearing beam 8 at different inclination angles, thus allowing the fixed load-bearing beam 8 to provide oblique support to the beam at different angles. Then, the control unit 16 starts the motor 14, which drives the threaded adjusting rod 2 to rotate. Because the threaded adjusting rod 2 has a threaded structure on its outer side... The threaded connection is made in the threaded through hole of the slider 3. The threaded adjusting rod 2 drives the slider 3 to move vertically up or down. The slider 3 drives the push-pull rod 6, which is hinged on the front side, to rotate. The push-pull rod 6 then drives the telescopic load-bearing beam 7, which is hinged at the top, to slide along the fixed load-bearing beam 8, thereby changing the nested combination length of the telescopic load-bearing beam 7 and the fixed load-bearing beam 8. This allows for quick adjustment of the protruding length range of the bracket support surface according to the beam support requirements. After adjustment, two sets of fastening bolts 11 are inserted into the long through grooves on the left and right sides of the fixed load-bearing beam 8, respectively. The two sets of fastening bolts 11 are screwed into the two sets of threaded holes of the telescopic load-bearing beam 7, so that the two sets of fastening bolts 11 clamp and fix the adjusted length of the fixed load-bearing beam 8 and the telescopic load-bearing beam 7, ensuring that the combined length structure of the fixed load-bearing beam 8 and the telescopic load-bearing beam 7 remains stable.
[0029] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies, and any method that achieves the desired effect can be implemented. The motor 14 and control unit 16 used above are common commercially available components; upon purchase and use, simply connect them according to the instruction manual provided with the purchase, and therefore will not be elaborated upon further.
