Description

Technical Field

[0001] This application relates to the field of bridge construction auxiliary equipment technology, and in particular to a temporary support structure for the installation of prefabricated components. Background Technology

[0002] During bridge construction, the installation of precast components is a crucial step. Temporary supports, as important auxiliary equipment supporting precast components, directly affect construction safety and efficiency. Temporary supports must provide stable support during the installation of precast components, bearing the self-weight of the components and construction loads, and can only be removed after the components are securely connected to the main structure.

[0003] Currently, most temporary supports are assembled and fixed by welding. Although this structural form can ensure a certain structural strength during construction, it has significant drawbacks: First, the welded temporary supports require cutting operations when disassembling, which is not only time-consuming and labor-intensive, but also easily damages the support components, making them difficult to reuse and increasing construction costs. Second, the welded temporary supports are usually integral structures with large volume and weight, requiring more transportation capacity during transport, and have poor flexibility in transportation and deployment in narrow construction sites, affecting the construction progress. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main objective of this application is to provide a temporary support structure for the installation of prefabricated components.

[0005] The technical solution of this application is as follows: a temporary support structure for prefabricated component installation, including pile foundations, wherein four pile foundations are provided, and a steel plate a is welded between the tops of the four pile foundations. Support columns are provided at the four corners of the top of the steel plate a. Fixing rings are fixedly connected to the outer side of each support column. Rotating seats are fixedly connected to both sides of each fixing ring. Diagonal bracing plates are rotatably installed inside each rotating seat. Two circular holes are opened at the adjacent ends of two diagonal bracing plates. Screws are inserted into the circular holes. Locking nuts are threaded to the outer side of the screws. Two diagonal bracing plates are connected by locking nuts and screws.

[0006] By adopting the above technical solution, the inclined brace plate is connected to the fixed ring through the rotating seat, which can flexibly adjust the construction angle of the inclined brace plate. Then, it is tightened by screws and locking nuts to form a triangular stable structure, which effectively disperses the load of the pier column.

[0007] In a preferred embodiment, each of the support columns is fixedly connected to a base, and several anchor rods are inserted into the base. The base is connected to the steel plate a through the anchor rods.

[0008] By adopting the above technical solution and setting anchor bolts, the support column can be installed on steel plate a, which also facilitates the subsequent disassembly and assembly of the support column.

[0009] In a preferred embodiment, the top of the four support columns is provided with a steel plate b, and the bottom of the steel plate b is provided with a slot that cooperates with the support column, and the slot is engaged with the corresponding support column.

[0010] By adopting the above technical solution, the slot and the support column can work together to achieve rapid connection between the support column and steel plate b, thereby improving the assembly effect of steel plate b.

[0011] In a preferred embodiment, each slot is fitted with a locking bolt a, and the support column is connected to the steel plate b via the locking bolt a.

[0012] By adopting the above technical solution and by setting the locking bolt a, the steel plate b can be installed on the support column.

[0013] In a preferred embodiment, a connector is provided between the four support columns, and the connector is fitted to the outer wall of each support column.

[0014] By adopting the above technical solution and setting the connectors, the connection tightness of the four support columns can be improved, making the support columns more stable during use.

[0015] In a preferred embodiment, a number of reinforcing ribs are fixedly connected between the support column and the base, and the number of reinforcing ribs are arranged at equal intervals.

[0016] By adopting the above technical solution and adding reinforcing ribs, the connection strength between the base and the support column can be improved.

[0017] In a preferred embodiment, a washer is fitted around the outer periphery of the screw, and the washer abuts against the inner wall of the locking nut and the brace plate.

[0018] By adopting the above technical solution, the gasket reduces the wear of the locking nut on the brace plate.

[0019] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0020] 1. In this application, the structure adopts a modular design, and each component can be transported separately: the support column, the bracing plate, steel plate a and steel plate b are independent components, which occupy little space during transportation and can save transportation capacity. At the same time, no cutting work is required during disassembly. Only the connecting parts such as bolts and screws need to be removed to complete the disassembly, avoiding damage to the components. This allows the components of the support to be reused multiple times, which greatly reduces material waste and construction costs.

[0021] 2. In this application, the diagonal brace is connected to the fixed ring via a rotating seat, which allows for flexible adjustment of the construction angle of the diagonal brace. It is then tightened by screws and locking nuts to form a stable triangular structure, which effectively disperses the load on the pier column, thereby improving the service life of the pier column.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Reference Figure 1-4A temporary support structure for prefabricated component installation includes four pile foundations 1. A steel plate a2 is welded between the tops of the four pile foundations 1. Support columns 3 are provided at the four corners of the top of the steel plate a2. Fixing rings 8 are fixedly connected to the outer sides of each support column 3. Rotating seats 9 are fixedly connected to both sides of each fixing ring 8. Diagonal bracing plates 10 are rotatably installed inside each rotating seat 9. Two circular holes 14 are opened at the adjacent ends of two diagonal bracing plates 10. Screws 11 are inserted into the circular holes 14. Locking nuts 13 are threaded onto the outer sides of the screws 11. The two diagonal bracing plates 10 are connected to the screws 11 via the locking nuts 13. This structure adopts a modular design. Each component can be transported separately: the pier column 3, the diagonal brace plate 10, the steel plate a2 and the steel plate b6 are independent components, which occupy little space during transportation and save transportation capacity. At the same time, no cutting is required during disassembly. Only the connecting parts such as bolts and screws 11 need to be removed to complete the disassembly, avoiding damage to the components. The components of the pier can be reused multiple times, which greatly reduces material waste and construction costs. In addition, the diagonal brace plate 10 is connected to the fixed ring 8 through the rotating seat 9, which can flexibly adjust the construction angle of the diagonal brace plate 10. It is then tightened by the screws 11 and the locking nuts 13 to form a triangular stable structure, which effectively distributes the load of the pier column 3, thereby improving the service life of the pier column 3.

[0029] Specifically, each of the four support columns 3 has a base fixedly connected to its bottom. Several anchor rods 4 are inserted into the base. The anchor rods 4 allow the support column 3 to be installed on the steel plate a2, facilitating subsequent disassembly and assembly of the support column 3. The base and steel plate a2 are connected by the anchor rods 4. Each of the four support columns 3 has a steel plate b6 at its top. The bottom of the steel plate b6 has a slot 15 that cooperates with the support column 3. Through the cooperation of the slot 15 and the support column 3, the support column 3 and steel plate b6 can be quickly connected, improving the assembly effect of steel plate b6. The slot 15 engages with the corresponding support column 3. Each slot 15 has a locking bolt a7 inserted inside. The support column 3 and steel plate b6 are connected by the locking bolt a7, allowing the steel plate b6 to be installed on the support column 3.

[0030] Specifically, connectors 16 are fitted between the four support columns 3. The connectors 16 are all in contact with the outer wall of the support column 3. The connection tightness of the four support columns 3 is improved by the connectors 16, making the support columns 3 more stable during use. Several reinforcing ribs 5 are fixedly connected between the support column 3 and the base. The reinforcing ribs 5 are arranged at equal intervals. Washers 12 are fitted on the outer periphery of the screw 11. The diagonal brace 10 is quickly connected to the screw 11 through the round hole 14. The washers 12 abut against the locking nut 13 and the inner wall of the diagonal brace 10.

[0031] Working principle: First, workers can use a welding torch to weld steel plate a2 onto the four pile foundations 1, and then use anchor rods 4 to fix the base below the pier column 3 onto the steel plate a2. Subsequently, the length of the screw rod 11 can be adjusted according to the construction situation. After adjustment, the screw rod 11 is locked using the locking nut 13. The diagonal brace plate 10 is connected to the fixing ring 8 via the rotating seat 9, allowing for flexible adjustment of the construction angle of the diagonal brace plate 10, thus forming a stable triangular structure that effectively distributes the load on the pier column 3, thereby improving the service life of the pier column 3. The connector 16 is then fitted onto the outer wall of the four pier columns 3, and the steel plate b6 is fixed to the pier column 3 using locking bolt a7. This structure adopts a modular design, and each component can be disassembled for transportation: the pier column 3, the diagonal brace plate 10, the steel plate a2 and the steel plate b6 are independent components, which occupy little space during transportation and can save transportation capacity. At the same time, no cutting is required during disassembly. Only the connecting parts such as bolts and screws 11 need to be removed to complete the disassembly, avoiding damage to the components. This allows each component of the pier to be reused multiple times, which greatly reduces material waste and construction costs.
