Problems solved by technology

In such a small width, it is necessary to support the formwork and wait for the reinforced concrete to have a certain strength before it can be dismantled, and the concrete will have a certain bond with the formwork, so it is difficult to remove the formwork, so the current industry status is not to dismantle the earthquake-proof formwork in the seam, which is extremely damaging to the two buildings in the event of an earthquake

Abstract

The invention provides an interlayer formwork for aseismatic joint construction, and a mounting method of the interlayer formwork. The interlayer formwork comprises a formwork body for formwork erecting and a supporting device connected with one side of the formwork body and used for supporting the formwork body, and a non-stick plate connected with a wall body is connected to the other side of the formwork body. By adopting a perlite plate, reinforced concrete does not make direct contact with an aluminum formwork, and thus the problem of cohesive force is solved. By adopting the aluminum formwork, a certain space is reserved for demounting the formwork. By adopting an adjustable screw rod, the construction difficulty is lowered.

Description

technical field [0001] The invention relates to the field of construction, in particular to a sandwich formwork used for seismic joint construction and an installation method thereof. Background technique [0002] Since the width of the seismic joint is very small, the width of the seismic joint of a frame structure building should not be less than 100mm when the height does not exceed 15m. 4m, 3m and 2m, it should be widened by 20mm. The width of the seismic joints of the frame-seismic wall structure buildings should not be less than 70% of the above-mentioned values, and the seismic joints of the seismic wall structure buildings should not be less than 50% of the above values, and none of them should be less than 100mm. In such a small width, it is necessary to support the formwork and wait for the reinforced concrete to have a certain strength before it can be dismantled, and the concrete will have a certain bond with the formwork, so it is difficult to remove the formwo...
