Description

Technical Field

[0001] This application relates to the field of steel formwork technology, and in particular to a steel formwork for the construction of bridge crash barriers. Background Technology

[0002] Bridge railings are guardrails installed on bridges. Their purpose is to prevent out-of-control vehicles from going off the bridge, and they also serve to prevent vehicles from breaking through, passing under, or overturning the bridge, as well as to beautify the bridge structure.

[0003] Steel formwork is required during the construction of bridge crash barriers. However, most existing steel formwork is connected by a large number of bolts. This connection method requires a lot of time to install, thus affecting the assembly efficiency of the steel formwork. Utility Model Content

[0004] To address the issue of low assembly efficiency in existing steel formwork, this application provides a steel formwork for bridge crash barrier construction.

[0005] This application provides a steel formwork for the construction of bridge crash barriers, including two formworks and side plates connected to the formworks. The outer walls of the two formworks and the side plates are provided with installation components, and a connecting mechanism connects the side plates and the installation components on the formworks.

[0006] By adopting the above structure, the concrete can be easily injected into the space between the template and the side plate through the cooperation between the two templates and the two side plates. The installation components facilitate the installation of the connecting mechanism between the side plate and the template.

[0007] The connecting mechanism includes a connecting seat, and the inner wall of the connecting seat has two symmetrically arranged sliding seats that are slidably connected.

[0008] By adopting the above structure, the sliding seat can be easily slidably installed through the connection base.

[0009] Both of the two connecting seats have openings on their outer walls on both sides, and the inner walls of both openings are slidably connected to connecting plates. Both of the connecting plates have a circular opening on one outer wall.

[0010] By adopting the above structure, the opening on the connector facilitates the sliding installation of the connector plate, and the round opening on the connector plate facilitates its connection to the mounting assembly.

[0011] Two fixing rods are fixedly connected to the inner walls of both sides of the connecting seat, and the two sliding seats are slidably connected to the outer walls of the four fixing rods respectively. The sliding seats are fixedly connected to the connecting plate.

[0012] By adopting the above structure, the sliding trajectory of the sliding seat can be easily restricted by the setting of the fixing rod, so as to avoid the sliding seat deviating during the sliding process.

[0013] The inner walls of both sides of the connector are rotatably connected to the same bidirectional screw, and the outer wall of the bidirectional screw is screwed with two symmetrically arranged threaded sleeves.

[0014] By adopting the above structure, the two threaded sleeves can be directly driven to move towards or away from each other when the bidirectional screw rotates.

[0015] Two drive plates are rotatably connected to the outer walls of the two threaded sleeves, and the four drive plates are rotatably connected to the two sliding seats respectively. A rotating part is rotatably connected to one side of the outer wall of the connecting seat, and one end of the drive shaft of the rotating part is fixedly connected to the bidirectional screw.

[0016] By adopting the above structure, the threaded sleeve is moved by the rotation of the bidirectional screw, which facilitates the movement of the sliding seat by the drive plate. The rotating part is designed to facilitate the rotation of the bidirectional screw.

[0017] The mounting assembly includes a mounting sleeve, and a threaded opening is provided on one outer wall of the mounting sleeve. A locking bolt is screwed onto the inner wall of the threaded opening, and the locking bolt passes through the circular opening.

[0018] By adopting the above structure, the locking bolt can be easily installed through the threaded port on the mounting sleeve, and the locking bolt can easily fix the connecting plate in the mounting sleeve by passing through the round port.

[0019] Two baffles are fixedly connected to one side of the outer wall of the side plate, and a groove matching the baffles is opened at one end of the template.

[0020] By adopting the above structure, the leakage of concrete from the mold cavity is prevented through the cooperation between the baffle and the groove on the side plate.

[0021] In summary, the beneficial effects of this application are as follows:

[0022] 1. This application provides a connecting mechanism between the template and the side plate. The connecting mechanism facilitates the connection between the side plate and the template, improves the connection efficiency between the two templates, and effectively reduces the use of bolts.

[0023] 2. This application provides multiple mounting components on the template and side panels. The mounting components facilitate the installation of the connecting mechanism, which in turn facilitates the disassembly and assembly of the connecting mechanism, thus making it convenient to reuse the template.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] Please see Figure 1-3 A steel formwork for bridge crash barrier construction includes two formworks 1 and side plates 4 connected to the formworks 1. The combination of the two formworks 1 and the two side plates 4 forms a mold. The mold formed by the combination of the formworks 1 and the side plates 4 facilitates the storage of concrete. The bridge railing can be formed by the molding of the concrete. The mold cavity between the formworks 1 and the side plates 4 facilitates the storage of concrete. The railing can be formed by waiting for the concrete to be molded. The outer walls of the two formworks 1 and the side plates 4 are provided with installation components 5. A connecting mechanism 2 is connected between the side plates 4 and the installation components 5 on the formworks 1. The installation components 5 facilitate the installation of the connecting mechanism 2 on the formworks 1 and the side plates 4. The connecting mechanism 2 facilitates the tightening of the side plates 4 on the formworks 1, thereby improving the stability of the connection between the formworks 1 and the side plates 4.

[0031] In use, the two templates 1 and the two side plates 4 cooperate to easily inject concrete into the space between the templates 1 and the side plates 4. The installation component 5 facilitates the installation of the connecting mechanism 2 between the side plates 4 and the templates 1.

[0032] Reference Figure 3 The connecting mechanism 2 includes a connecting seat 8, and two symmetrically arranged sliding seats 12 are slidably connected to the inner wall of the connecting seat 8. The outer walls of the two sliding seats 12 are provided with air holes. The connecting seat 8 facilitates the sliding installation of the sliding seats 12.

[0033] Reference Figure 3 and Figure 4 Both sides of the outer wall of the two connecting seats 8 are provided with openings, and the inner walls of the two openings are slidably connected with connecting plates 9. The two connecting plates 9 are symmetrically arranged so that the side plates 4 can be tightened when sliding. Both sides of the outer wall of the two connecting plates 9 are provided with round openings 10. The openings on the connecting seats 8 facilitate the sliding installation of the connecting plates 9. The round openings 10 on the connecting plates 9 facilitate their connection to the mounting components 5.

[0034] Reference Figure 3-4 Two fixed rods 16 are fixedly connected to the inner walls of both sides of the connecting seat 8. The four fixed rods 16 are symmetrically arranged. Two sliding seats 12 are slidably connected to the outer walls of the four fixed rods 16 respectively. When the sliding seat 12 slides on the fixed rods 16, the stability of the sliding seat 12 is ensured. The sliding seat 12 is fixedly connected to the connecting plate 9. When the sliding seat 12 moves, it directly drives the connecting plate 9 to move. The setting of the fixed rods 16 makes it easy to limit the sliding trajectory of the sliding seat 12 and avoid the sliding seat 12 from deviating during the sliding process.

[0035] Reference Figure 3 and Figure 4 The inner walls of both sides of the connecting seat 8 are rotatably connected to the same bidirectional screw 13. The bidirectional screw 13 is rotatably installed at the center line of the connecting seat 8, and the outer wall of the bidirectional screw 13 is screwed with two symmetrically arranged threaded sleeves 14. When the bidirectional screw 13 rotates, it drives the two threaded sleeves 14 to move towards or away from each other. The rotation of the bidirectional screw 13 directly drives the two threaded sleeves 14 to move towards or away from each other.

[0036] Reference Figure 4 Two drive plates 15 are rotatably connected to the outer walls of the two threaded sleeves 14, and the four drive plates 15 are rotatably connected to the two sliding seats 12 respectively. When the two threaded sleeves 14 move towards each other, they cooperate with the drive plates 15 to push the two connecting plates 9 to move apart. When the two threaded sleeves 14 move apart, they directly cooperate with the drive plates 15 to drive the two connecting plates 9 to move towards each other. A rotating part 11 is rotatably connected to one side of the outer wall of the connecting seat 8, and one end of the drive shaft of the rotating part 11 is fixedly connected to the bidirectional screw 13. The rotation of the bidirectional screw 13 drives the threaded sleeves 14 to move, which facilitates the cooperation of the drive plates 15 to drive the sliding seats 12 to move. The setting of the rotating part 11 facilitates the rotation of the bidirectional screw 13.

[0037] Reference Figure 2 The mounting component 5 includes a mounting sleeve 6, and a threaded opening is provided on one outer wall of the mounting sleeve 6. The mounting sleeve 6 has a rectangular structure, and a locking bolt 7 is screwed into the inner wall of the threaded opening. The locking bolt 7 passes through the mounting sleeve 6 and passes through the round opening 10. The locking bolt 7 can be easily installed through the threaded opening on the mounting sleeve 6, and the locking bolt 7 passing through the round opening 10 can easily fix the connecting plate 9 in the mounting sleeve 6.

[0038] Reference Figure 1-2 Two baffles 17 are fixedly connected to one side of the outer wall of the side plate 4. A groove 3 matching the baffle 17 is opened at one end of the template 1. The baffle 17 can be inserted into the groove 3 to seal the space between the template 1 and the side plate 4, effectively preventing leakage of concrete after injection. The cooperation between the baffle 17 and the groove 3 on the side plate 4 prevents the concrete in the mold cavity from leaking out.

[0039] The implementation principle of this application is as follows: When in use, first fix two templates 1 on the bridge, and then connect the side plate 4 to the two templates 1 through four connecting mechanisms 2. During installation, first insert the connecting plate 9 on the connecting mechanism 2 into the mounting sleeve 6, and then fix it to the mounting sleeve 6 through the locking bolt 7 passing through the round hole 10. When tightening the side plate 4, directly rotate the rotating part 11. When the rotating part 11 rotates, it directly drives the bidirectional screw 13 to rotate. When the bidirectional screw 13 rotates, it directly drives the two threaded sleeves 14 to move towards or away from each other. When the two threaded sleeves 14 move away from each other, it directly cooperates with the drive plate 15 to pull the two connecting plates 9 to move towards each other. When the two connecting plates 9 move towards each other, it is convenient to tighten the side plate 4 on the template 1.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
