Reinforcing steel bar processing apparatus used for foundation pit support column and floor slab joint and usage method thereof

Abstract

The invention relates to the field of a special-purpose connecting piece used for a floor slab structure, and specifically relates to a reinforcing steel bar processing apparatus used for a foundationpit support column and a floor slab joint and a usage method thereof. The reinforcing steel bar processing apparatus used for the foundation pit support column and the floor slab joint includes pipecolumns (1), and is characterized in that apparatus further comprises connecting plates (2), outer reinforcing steel bars (3) and inner reinforcing steel bars (4), and the inner ends of the connectingplates (2) are attached and fixed to the outer side surfaces of the pipe columns (1); the outer reinforcing steel bars (3) are all fixed on the connecting plates (2); and the inner reinforcing steelbars (4) are embedded in inner cavities of the pipe columns (1). The reinforcing steel bar processing apparatus used for the foundation pit support column and the floor slab joint and the usage methodthereof are characterized by being implemented in order according to the following steps: a. fixing the connecting plates; b. pouring a floor slab; c. cutting off the pipe columns; and d. pouring thepipe columns. The apparatus and the method are simple in structure, are convenient to construct, enable materials to be saved, and are safe and reliable.

Description

Technical field [0001] The invention relates to the field of special connectors for floor slab structures, in particular to a steel bar processing device used for foundation pit supporting columns and floor nodes and a method of use thereof. Background technique [0002] In deep foundation pit support projects, especially when the area of ​​the foundation pit is large, gussets and counter braces are usually set. In some projects, trestle bridges are usually set for excavation, excavation and subsequent material turnover. The force is often large, and the vertical use of lattice columns cannot meet the requirements of use and safety. Therefore, the form of round pipe columns is usually adopted. The round pipe columns are pre-embedded in the cast-in-place pile during the pile foundation construction, and the pipe is filled with concrete. During the construction of the basement structure, the round pipe column and the floor joints are usually constructed with reserved holes. This me...

Problems solved by technology

[0002] In deep foundation pit support projects, especially when the area of ​​the foundation pit is large, corner braces and counter braces are usually set up. In some projects, trestles are usually set up for excavation, excavation and subsequent material turnover. The force is often very large, and the vertical use of lattice columns cannot meet the use and safety requirements. Therefore, the form of circular tube columns is usually used. The circular tube columns are pre-embedded in the cast-in-place piles during pile foundation construction, and the tubes are filled with concrete.

In the construction process of the basement structure, the joints between the circular pipe column and the floor are usually constructed in the way of reserved holes. In the case of deep foundation pits, the ratio of length to diameter of the steel pipe column is relatively large, and the load on the upper part is relatively large. In a large case, it is easy to lose stability and cause the foundation pit to collapse
