Reusable concrete floor steel bar pre-supporting device

Abstract

The invention relates to a reusable concrete floor steel bar pre-supporting device, which comprises four upright posts, a square positioning steel plate, hanging arm supporting arms, steel bar hanging arms and pulling arms. Due to the structure, the device is processed in a factory to ensure processing accuracy, and is suitable to be used at the cross junction of steel bars, and a floor steel bar layer is accurately positioned; L-shaped right-angle steel bar hooks are located at opposite positions by pulling the pulling arms, so that the lifted steel bars are oppositely fixed and cannot slide; after concrete is poured, the L-shaped right-angle steel bar hooks are rotated to be located at withdrawable positions by pulling the pulling arms during surface finishing, and the steel bar pre-supporting device is taken out, cleaned and reused; and meanwhile, the extension length of the steel bar hanging arms can be adjusted according to the thickness of a floor, the four upright posts with appropriate length can be replaced when the adjusted steel bar hanging arms cannot meet the actual requirement. The device has a simple structure, is convenient to assemble and disassemble and can be rented and turned over, construction cost is reduced, and the input of construction personnel is reduced.

Description

technical field [0001] The invention belongs to the field of auxiliary tools during construction of building structures, in particular to a reusable pre-supporting device for steel bars on concrete floors, which is a tool for controlling the position of upper steel bars on concrete floors during construction of building structures. Background technique [0002] In the construction stage of the building structure, when pouring the concrete floor, the position control of the steel bars on the floor is particularly important, especially the control of the upper steel bars is difficult. Usually, the steel bar stool is used to control the position of the upper steel bar on the floor. Since the steel bar stools are all made on site , there are problems such as large processing deviation and unguaranteed welding quality, which leads to the frequent opening and welding of steel bar stools during use, resulting in quality problems in floor construction. The concrete cannot be taken o...

Problems solved by technology

[0002] In the construction stage of the building structure, when pouring the concrete floor, the position control of the steel bars on the floor is particularly important, especially the control of the upper steel bars is difficult. Usually, the steel bar stool is used to control the position of the upper steel bar on the floor. Since the steel bar stools are all made on site , there are problems such as large processing deviation and unguaranteed welding quality, which leads to the frequent opening and welding of steel bar stools during use, resulting in quality problems in floor construction. The concrete cannot be taken out and cannot be reused. As a result, a large number of steel bar stools used in each project have become consumables. Each construction requires a lot of manpower and financial resources to prepare steel bar stools. The manpower input is large and the construction cost increases.
