Description

Technical Field

[0001] The utility model relates to the field of earthquake-resistant technology, in particular to an earthquake-resistant frame structure with adjustable size. Background Art

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. In the construction process of construction engineering, formwork support for earthquake resistance is an important step in the construction process. It is a support for cast-in-place concrete in housing construction, and its main function is to support earthquake resistance. During the construction process, formwork support for earthquake resistance is used to offset the disturbance caused by the upper operation and avoid mold explosion.

[0003] Early formwork-supported earthquake-resistant frames were mostly made of wooden bars or iron pipes. Later formwork-supported earthquake-resistant frames generally used steel or wooden beams to assemble formwork brackets, and used steel or wooden poles to build scaffolding to form brackets to support earthquake resistance. Since there is a certain error in the horizontality of the building formwork, the height needs to be constantly adjusted during earthquake support. At present, the fit with the formwork is generally achieved through the cooperation of top screws and wooden squares. First, the wooden square is in contact with the formwork, and one end of the top screw is placed in the steel pipe. The position of the external threaded sleeve is adjusted to adjust the height of the top screw, so that the top screw and the wooden square are in contact to achieve earthquake support. However, when pouring concrete, the pouring position will be subject to a sudden increase in pressure, and the pressure is directly absorbed by the wooden square top screws and steel pipes. The instantaneous vibration generated when the concrete is released cannot be absorbed and buffered, and there is a certain risk.

[0004] Based on this, the utility model designs a size-adjustable earthquake-resistant frame structure to solve the above problems. Utility Model Content
