Description

Technical Field

[0001] The invention relates to the technical field of cantilever formwork reinforcement, and in particular to a cantilever formwork auxiliary reinforcement device for water conservancy construction. Background Art

[0002] The spillway is a flood control facility of the dam. It is built on one side of the dam like a large trough. When the water level in the reservoir exceeds a certain limit, the water flows downstream from the spillway to prevent the dam from being destroyed. Guide walls are set on both sides of the slope of the dam spillway. In order to prevent the water from overflowing to the outside of the guide wall, a water pressure plate is set on the inner side of the spillway at the top of the guide wall. The water pressure plate is in the form of a cantilevered corbel. In the construction of the guide wall corbel concrete, since the corbel is in a cantilevered form and is constructed synchronously with the top slope of the guide wall concrete, the conventional method of corbel construction is to use an inner pull structure to reinforce and support the corbel cantilever formwork; however, this method can only provide inner pull support for the inner side of the corbel cantilever formwork, and the outer facade of the corbel cantilever formwork is suspended on the outside and cannot be supported, so during the pouring process, the corbel cantilever formwork is prone to loosening and running, and the stability is insufficient; therefore, we propose a cantilever formwork auxiliary reinforcement device for water conservancy construction to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings existing in the background technology and to propose a cantilever formwork auxiliary reinforcement device for water conservancy construction.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: an auxiliary reinforcement device for a cantilever formwork for water conservancy construction, comprising: a working platform, a mounting hole, an embedded bolt, a reinforcement rod, a fence platform, a positioning hole, a fence, a positioning column, a base, a first threaded hole, a mounting seat, a second threaded hole, a fixing bolt, a first support rod, a threaded cavity, a threaded rod, a second support rod, a handrail, a first rotating shaft, a rotating seat, a second rotating shaft, a connecting seat, a support seat, a spring, and a support plate. The working platform has mounting holes fixedly installed on both sides of the bottom surface, embedded bolts are movably installed inside the mounting holes, reinforcement rods are fixedly installed on both sides of the bottom of the working platform, a fence platform is fixedly installed at the edge of the working platform, positioning holes are fixedly installed on both sides of the surface of the fence platform, a plurality of fences are movably installed on the top of the fence platform, positioning columns are fixedly installed on both sides of the bottom of the fence, and the positioning columns are movably installed in the positioning holes. The top of the mounting plate is provided with a first spring, and the bottom of the second spring is provided with a second threaded hole, and the second threaded hole is provided with a fixing bolt.

[0005] Preferably, the first support rod corresponds to the second support rod up and down, and the threaded rod is threadably connected to the inside of the threaded cavity.

[0006] Preferably, the springs are arranged in an array structure, and the bottom of the support plate is adapted to the inside of the support seat.

[0007] Preferably, the support base can rotate by a maximum range of 180° through the second rotating shaft.

[0008] Preferably, the mounting seat and the interior of the base are inlaid structures, and the first threaded holes correspond to the second threaded holes one by one, and the fixing bolts are both threadedly connected to the interior of the first threaded holes and the second threaded holes.

[0009] Preferably, the fence is provided with three pieces, and the positioning posts and the interior of the positioning holes are inlaid structures.

[0010] Preferably, the embedded bolt is connected to the inner thread of the mounting hole.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) The second support rod can be driven to rotate and move by rotating the handrail, and the second support rod can synchronously drive the threaded rod and the inside of the threaded cavity to rotate and move, so that the height of the second support rod can be adjusted, thereby the support height of the support seat and the support plate can be adjusted synchronously, so that when there is a height difference between the support plate and the cantilever formwork, the height of the support plate can be adjusted to a suitable position, so that the support plate can be closely attached to the outer surface of the cantilever formwork to support it, thereby improving the installation stability of the cantilever formwork by reinforcing the outer surface of the cantilever formwork, and preventing the formwork from loosening and running.

[0013] (2) When the support plate is in close contact with the outer surface of the cantilever formwork, the spring can be compressed and deformed, thereby driving the bottom of the support plate to move elastically inside the support seat through the elastic force of the spring, so that the spring always gives the support plate an upward impulse, so that the support plate can elastically support the outer surface of the cantilever formwork, making the support plate more closely fit the outer surface of the cantilever formwork, which can further improve the support stability. At the same time, the spring can also absorb the impact and vibration energy caused by pouring concrete inside the cantilever formwork, which can reduce damage to key components.

[0014] (3) The support base can be driven by the second rotating shaft to rotate 180°, and the support base can simultaneously drive the support base and the support plate to rotate 180°, so that the angles of the support base and the support plate can be adjusted to the appropriate position according to the inclination angle of the cantilever formwork facade, so that the surface of the support plate can be just adapted to support the cantilever formwork facade, thereby supporting the cantilever formwork facade at different angles, which can improve practicality.

[0015] (4) The working platform can be used to carry construction workers, and the fence at the edge of the working platform can protect the safety of construction workers. The positioning column is embedded in the positioning hole, so that the positioning column can be easily detached from the positioning hole, so that the fence can be removed from the fence platform, making the fence easy to disassemble and use.

[0045] The construction workers can be carried by the working platform 1, and the safety of the construction workers can be protected by the fence 7 at the edge of the working platform 1. The positioning column 8 is embedded in the positioning hole 6, so that the positioning column 8 can be easily separated from the positioning hole 6, so that the fence 7 can be removed from the fence platform 5, so that the fence 7 is easy to disassemble and use;

[0046] At the same time, the second rotating shaft 21 can drive the support seat 23 to rotate and adjust by 180°, and the support seat 23 can synchronously drive the support seat 23 and the support plate 25 to rotate and adjust by 180°, so that the angles of the support seat 23 and the support plate 25 can be adjusted to support the appropriate position according to the inclination angle of the cantilever formwork facade, so that the surface of the support plate 25 can just fit and support the cantilever formwork facade, so that the cantilever formwork facades at different angles can be supported, which can improve practicality;
