Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, and in particular to a bottomless support assembled triangular bracket with an unloading function. Background Art

[0002] There are more and more construction process designs for continuous beam segments of bridges in my country, and the construction of the zero block of the continuous beam segment and the construction of the diaphragm of the pier design cannot be separated from the triangular bracket. The load-bearing of the traditional triangular bracket requires the pre-embedded horizontal support rod at the bottom of the vertical rod of the triangular bracket. The vertical rod of the triangular bracket is directly located on the horizontal support rod to assist in the force bearing. The work of pre-embedding the horizontal support rod is very complicated, and it cannot be unloaded after pre-embedding. It can only be buried in the concrete body of the pier forever. If multi-layer diaphragms are to be constructed on super-high piers, it is necessary to continuously embed many horizontal support rods in the concrete body. The traditional triangular bracket itself does not have the unloading function. Unloading requires a separate unloading steel sand bucket or other unloading tools to be set up on its upper part, and the installation process is relatively cumbersome. Utility Model Content

[0003] The purpose of the utility model is to provide a bottomless support assembled triangular bracket with an unloading function to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bottomless support assembled triangular bracket with unloading function, which includes a pier column, a plurality of embedded connecting parts are fixedly arranged on the upper and lower sides of the pier column, the embedded connecting part at the top is horizontally fixedly connected to an upper cross beam, a diagonal support rod is fixedly connected to the upper cross beam, the other end of the diagonal support rod is fixedly connected to the embedded connecting part at the bottom, a plurality of steel wedges are evenly installed on the upper cross beam, a top rod is fixedly installed on the top of the steel wedge, and a bottom mold is arranged on the top of the top rod.

[0005] Preferably, the middle portion of the diagonal brace is fixedly connected to a first reinforcing rod by welding, and the other end of the first reinforcing rod is fixedly connected to the pier column by the embedded connecting piece.

[0006] Preferably, the middle portion of the diagonal brace is fixedly connected to a second reinforcing rod obliquely upward by welding, and the other end of the second reinforcing rod is fixedly welded to the root of the upper cross beam.

[0007] Preferably, the upper cross beam and the diagonal bracing rod are fixedly connected to the embedded connecting parts by welding.

[0008] Beneficial effect: Compared with the prior art, the beneficial effect of the utility model is that the setting of the steel wedge block realizes effective support for the bottom mold by gradually pressing the steel wedge block from one side to the other side. When unloading is required, the steel wedge block can be pulled out from one side to remove the support for the bottom mold. The operation is simple, safe and reliable, and the installation process is simplified. BRIEF DESCRIPTION OF THE DRAWINGS
