Lattice column suitable for insertion with stand column pile and preparation method thereof

Abstract

The invention discloses a lattice column suitable for insertion with a stand column pile. The lattice column comprises a non-insertion section with a first section size, an insertion section with a second section size, and a plate body positioned between the non-insertion section and the insertion section, wherein the end surface of the non-insertion section is tightly connected with the surface of one side of the plate body, and is tightly connected through multiple angle steel; the end surface of the insertion section is tightly connected with the surface of the other side of the plate body, and is tightly connected through multiple angle steel; the non-insertion section and the insertion section are coaxial; and the maximum length of the section of the insertion section is smaller than the inner diameter of a reinforcement cage, so that the insertion section can be inserted in the reinforcement cage, and the surface of the plate body butts against the end surface of the reinforcement cage to realize insertion between the lattice column and the stand column pile. The invention further discloses a corresponding preparation method. Through optimization and improvement of the lattice column structure, the insertion end is set as the section size suitable for the reinforcement cage of the stand column pile to realize reliable insertion between the lattice column and the stand column pile, so that the increment of the pile diameter is not needed, the construction difficulty cannot be increased, and the safety strength of the structure cannot be reduced.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a lattice column suitable for plugging and connecting with column piles and a preparation method thereof. Background technique [0002] For foundation pit projects with horizontal internal supports, it is generally necessary to set up a vertical support system to bear the load such as the self-weight of the supporting rods. The vertical support system of the foundation pit usually adopts the form of lattice columns inserted into the column pile foundation. Inserting the lattice column into the column pile needs to ensure that within the insertion range, the inner diameter of the reinforcement cage of the column pile is greater than the diagonal length of the lattice column. Therefore, in the design process of the vertical support system of the foundation pit, the section size of the lattice column needs to meet the bearing capacity requirements, and ...

Problems solved by technology

Although the above scheme is only a part of increasing the pile diameter within the range of the column, it will still increase the amount of empty piles and real piles of the column piles, resulting in unnecessary engineering costs, and this kind of steel cage and column structure with a slope will Increased construction difficulty and reduced structural safety strength
