Early dismantling device suitable for various standard profiles

Abstract

The invention relates to an early dismantling device suitable for various standard profiles. The early dismantling device comprises a tray, wherein a cylinder is fixedly connected to the lower surface of the tray, a threaded steel pipe is connected to the interior of the cylinder in the axis direction of the cylinder in a sliding mode, at least two clamping parts are fixedly connected to the edge, away from the surface of the cylinder, of the tray, the clamping parts are uniformly distributed at the edge of the tray, a threaded buckle is in threaded connection with the threaded steel pipe, the threaded buckle is located on the side, away from the tray, of the cylinder, a locking assembly which is used for preventing the cylinder and the threaded steel pipe from rotating is arranged between the cylinder and the threaded steel pipe, a base is fixedly connected to the threaded steel pipe, the base is located on the side, away from the cylinder, of the threaded buckle, connecting angle steel is connected to the edge of the base, a jacking is connected to one end of the connecting angle steel, and the jacking is located on the side, away from the cylinder, of the tray. The early dismantling device has the effect of keeping primary and secondary beams horizontal and is suitable for various profiles.

Description

technical field [0001] The application relates to the field of building construction formwork support systems, in particular to an early dismantling device adaptable to various standard profiles. Background technique [0002] During the construction process, the overall concrete pouring needs to be completed by setting up formwork through the support system. After the concrete strength meets the design requirements, the formwork and support system are removed. In addition to the concrete design strength, the demolition conditions are related to the component span. When the component span is ≤ 2m, the design concrete strength grade value is ≥ 50%; when the component span is > 2m and ≤ 8m, the design concrete strength grade value is ≥ 75% % demolition; when the component span>8m, reach the design concrete strength grade value ≥100% demolition. Conventional forms and supports need to reach 100% to be removed, and the early formwork removal technology is to use the time d...

Problems solved by technology

[0003] In the traditional formwork support system in the past, the main beam was placed on the top of the formwork support system, the secondary beam was placed above the main beam, and the pouring formwork was placed above the secondary beam. Due to the unreasonable design structure of the formwork support system with early demolition function, the formwork support system The main girder cannot be accurately limited, resulting in a large inclination of the main girder and the secondary girder, which is easily deformed after repeated use, thus bringing a major safety hazard to the construction, and the early demolition device is applicable to a single type of beam , the degree of generalization is not high
