Description

Technical Field

[0001] The invention belongs to the technical field of steel structure construction, and in particular relates to a rapid supporting and positioning device for a bridge diaphragm. Background Art

[0002] During the assembly of bridge diaphragms, when the traditional method of assembly and positioning is used, in order to prevent the diaphragms from tipping over and injuring people during the assembly and welding process, and also to ensure accurate positioning and reduce assembly deformation, two steel supports need to be welded on both sides of the diaphragm. If the steel supports are not used in a suitable project after being removed after use, they are generally discarded and difficult to reuse. The welding position of the diaphragm and the top (bottom) plate will leave weld scars, which require a lot of manpower and material resources to polish, and will cause certain damage to the parent material.

[0003] The applicant's prior application CN115156800 A discloses a supporting fixture for partition installation, which can improve the installation efficiency and quality of steel partitions and ensure the safety of construction workers. The clamping seat of the supporting fixture for partition installation forms a groove structure, and the hollow part in the middle is used to clamp to the protruding part of the partition. Then, by installing the clamping bolt, the clamping bolt can only lock the partition, and then lock the clamping part. And through the screw-in amount of the clamping bolt, it can adapt to the clamping of partitions of different thicknesses. However, when using this solution, the protruding part of the partition and the groove of the clamping seat need to be precisely aligned, otherwise it may cause installation failure or loose fixation. Under long-term use or in a vibrating environment, the clamping bolt may loosen, resulting in loose fixation of the partition, affecting the stability and safety of the structure. In addition, repeated disassembly or long-term use may cause wear on the contact surface between the clamping seat and the partition, reducing the clamping effect.

[0004] Therefore, it is necessary to improve the above-mentioned supporting tooling to solve its technical problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a rapid supporting and positioning device for bridge diaphragms, so as to at least solve part of the above-mentioned technical problems.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0007] A bridge diaphragm quick support positioning device comprises a fixing mechanism installed on a U-rib, and two positioning and adjusting mechanisms installed between a diaphragm stiffening plate and the fixing mechanism; the positioning and adjusting mechanism comprises a stiffening plate U-shaped clamp matched with the diaphragm stiffening plate, a fastening mechanism arranged on the stiffening plate U-shaped clamp for fastening the diaphragm stiffening plate in the stiffening plate U-shaped clamp, and an adjusting rod connected between the stiffening plate U-shaped clamp and the fixing mechanism;

[0008] The fastening mechanism includes a through hole opened on the stiffening plate U-shaped clamp, a fastening internal threaded tube arranged on the stiffening plate U-shaped clamp and connected to the through hole, and a threaded rod threadedly connected to the fastening internal threaded tube; one end of the threaded rod passes through the through hole and extends into the stiffening plate U-shaped clamp, and one end of the threaded rod is provided with a tightening plate that contacts the partition stiffening plate.

[0009] Furthermore, a bearing is welded on the tightening plate, and one end of the threaded rod is tightly fitted and fixed in the inner ring of the bearing.

[0010] Furthermore, a cross-shaped handle is provided at the other end of the threaded rod to tighten the internal threaded tube and to be coaxially distributed with the through hole.

[0011] Furthermore, the adjusting rod includes a first threaded column connected to the U-shaped clamp of the stiffening plate, a second threaded column connected to the fixing mechanism, and an internal threaded tube with two ends respectively threadedly connected to the first threaded column and the second threaded column.

[0012] Furthermore, a first connecting ear is provided on the first threaded column, a first clamp seat is provided on the stiffening plate U-shaped clamp, a first clamp seat installation groove is opened on the first clamp seat, and the first connecting ear is installed in the first clamp seat installation groove by bolts.

[0013] Furthermore, a second connecting ear is provided on the second threaded column, and the second connecting ear is connected to the fixing mechanism through a bolt.

[0014] Furthermore, the fixing mechanism comprises a U-shaped fixing clamp fixedly mounted on the U-rib by bolts, and the U-shaped fixing clamp is provided with a mounting mechanism for mounting the adjusting rod.

[0015] Furthermore, the mounting mechanism includes three mounting ears arranged side by side on the top of the U-shaped fixing clamp, and fixing pins passing through the three mounting ears; a mounting groove for mounting the adjusting rod is formed between two adjacent mounting ears.

[0016] Furthermore, the angle between one of the two positioning adjustment mechanisms and the U-rib is less than 20°, and the angle between the other and the U-rib is 65°-85°.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention has a simple structure, a scientific and reasonable design, and is easy to use. During the assembly process of the partition, the present invention innovatively changes the traditional partition's welded fixed support into an adjustable assembled connected fixed support, which can effectively reduce material loss, ensure product quality, and improve work efficiency while ensuring safety.

[0019] The bridge partition quick support and positioning device of the present invention is simple to construct and has precise positioning, which can effectively improve work efficiency, reduce material loss, ensure product quality, reduce manual labor intensity and related material energy consumption, and the device can be disassembled after use and reused.

[0020] The invention provides a more stable fixing effect by fastening the partition at multiple points through the stiffening plate U-shaped clamp and the fastening mechanism, and reduces the risk of loosening caused by vibration or external force. The fastening mechanism includes a threaded rod and a top tightening plate, which can evenly apply force to ensure the stability of the partition in all directions.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] The fastening mechanism includes a through hole 7 opened on the stiffening plate U-shaped clamp 5, a fastening internal threaded tube 8 arranged on the stiffening plate U-shaped clamp 5 and connected to the through hole 5, and a threaded rod 9 threadedly connected to the fastening internal threaded tube 8; one end of the threaded rod 9 passes through the through hole 7 and extends into the stiffening plate U-shaped clamp 5, and one end of the threaded rod 9 is provided with a tightening plate 10 that contacts the partition stiffening plate 3.

[0041] By rotating the threaded rod 9, the top plate 10 can be made to press against the partition stiffening plate 3 to fix the partition stiffening plate 3 in the stiffening plate U-shaped clamp 5, or the partition stiffening plate 3 can be loosened to remove the stiffening plate U-shaped clamp 5 from the partition stiffening plate 3, which is very convenient for disassembly and assembly. The tightening internal threaded tube 8 is perpendicular to the top surface of the stiffening plate U-shaped clamp 5 and also perpendicular to the contact surface of the partition stiffening plate 3. On the one hand, the tightening internal threaded tube 8 plays a guiding role, so that the tightening force direction of the threaded rod 9 is perpendicular to the partition stiffening plate 3. On the other hand, the threaded connection between the tightening internal threaded tube 8 and the threaded rod 9 can also provide sufficient pre-tightening force for the threaded rod 9, so that the stiffening plate U-shaped clamp 5 and the partition stiffening plate 3 remain in a tightened state.

[0042] The present invention has a simple structure, a scientific and reasonable design, and is easy to use. During the assembly process of the partition, the present invention innovatively changes the traditional partition's welded fixed support into an adjustable assembled connected fixed support, which can effectively reduce material loss, ensure product quality, and improve work efficiency while ensuring safety.
