AI Technical Summary

Technical Problem

It is difficult for existing aluminum alloy formwork to effectively discharge water and gas during concrete pouring, resulting in defects such as pores, lump surfaces and hollows after the concrete solidifies, affecting the molding effect and safety performance of the building.

Method used

An aluminum alloy template with water gas discharge function is designed. By providing a multi-layer water gas discharge mechanism at the connection between the first formwork and the second formwork, including a primary filter part, a fine filter part and a pressure relief part, it is ensured that the moisture and gas in the concrete can be quickly released during the pouring and vibration process.

Benefits of technology

It effectively avoids defects such as holes and lump surfaces on the surface after concrete solidification, improves the molding effect and safety performance of the building body, and at the same time shortens the solidification time of concrete structural parts, compresses the construction cycle, and improves the construction quality.

Abstract

The invention relates to the technical field of building formworks, in particular to a building aluminum alloy formwork with a water and gas discharging function and a construction method. Comprising a first template and a second template which are connected with each other, a water vapor discharging mechanism is arranged between the first template and the second template, the water vapor discharging mechanism comprises a primary filtering part, a fine filtering part and a pressure relief part, the primary filtering part and the pressure relief part are both arranged on the second template, the fine filtering part is embedded in the first template, and when the first template is connected with the second template, the fine filtering part is embedded in the first template. The fine filtering part is in contact with the primary filtering part, the pressure relief part is matched with the fine filtering part, the primary filtering part and the fine filtering part are used for filtering concrete impurities, and high-pressure steam in the fine filtering part is discharged emergently through the pressure relief part. Under the condition of ensuring that the concrete is not lost, gas and excessive water in the concrete are effectively discharged, the solidification time of a concrete structural part is shortened, the defects of holes, pitted surfaces and the like on the surface of the concrete after the concrete is solidified are avoided, the water in the concrete is discharged in time, and the construction quality is improved.
