AI Technical Summary
The hollow structure of the existing unloading block causes the stress performance of the left and right support when the pulling screw is inserted, and there is a cavity when the unloading block is closed, limiting the bearing capacity.
A solid detachment block is designed, and a horizontal screw is connected to the arc-shaped ear hole plate. The sliding and disassembly of the left and right support is achieved through sliding and nut locking. Combined with the horizontal and longitudinal reinforcement ribs, it forms an isosceles trapezoidal horizontal line. The cross-section avoids openings in the abdomen of the support and forms a solid structure when closed.
The stress performance of the left and right support is improved, the cavity in the middle of the unloading block is eliminated, and the bearing capacity and overall bearing capacity of the unloading block are significantly improved.

[0002] The drop block is a commonly used construction equipment in cast-in-place construction of bridges. It is located between the support and the formwork and is used to dismantle the support and the formwork. When the formwork needs to be dismantled, the drop block is removed first, and the formwork then falls off the beam.
[0003] The existing unloading block is generally composed of an upper support, a lower support, a left support, a right support and a tension screw, wherein the tension screw usually crosses the abdomen or middle of the left support and the right support, and when the unloading block is completely closed, there is a cavity in the middle of the unloading block, that is, the existing unloading block is a hollow structure from the overall perspective, see the patent documents such as the authorization announcement numbers CN218540442U, CN216712746U, CN216040713U, CN206189273U, etc. Although the existing hollow unloading block structure has certain advantages, it still has the following disadvantages:
[0004] (1) The tension screw is inserted horizontally through the abdomen or middle of the left support and the right support, and a hole needs to be opened in the abdomen or middle of the left support and the right support, which will affect the force performance of the left support and the right support, thereby reducing the bearing capacity of the left support and the right support;
[0005] (2) When the unloading block is closed, there is a cavity in the middle, which will limit the bearing capacity of the entire unloading block to a certain extent. Utility Model Content
