Formwork of cast-in-place fair-faced concrete fire barrier

Abstract

The invention discloses a formwork of a cast-in-place fair-faced concrete fire barrier. According to the formwork, a square frame is made up of two vertical square steels and two transverse square steels, vertical square steels are uniformly distributed in the square frame, triangular connecting plates are separately arranged between each vertical square steel and each transverse square steel of the square frame, angle steels are uniformly distributed on inner side surfaces of left and right square steels, angle steels are uniformly distributed on left and right surfaces of each of the vertical square steels uniformly distributed in the square frame, self-tapping screw via holes opposite to wooden forms are separately formed in each triangular connecting plate and each angle steel, the wooden forms are placed on surfaces of the square steels of the square frame, the wooden forms and the square steels in the square frame are integrated through self-tapping screws, joints among the wooden forms are opposite to end faces of the square steels in the square frame, and foam rubber gaskets are stuck to the end faces, opposite to the joints of the wooden forms, of the square steels. Compared with the prior art, the formwork has the remarkable advantage that the surface of the concrete is free of water seepage, mortar leakage, black edges and slab staggering.

Description

technical field [0001] The invention relates to a building template, in particular to a cast-in-place fair-faced concrete firewall template. Background technique [0002] During the construction of the converter station, there is a special-shaped firewall, that is, a vertical valve hall firewall and multiple horizontal firewalls. During the construction, the formwork needs to be reinforced and installed, and the joints between the formwork are prone to laxness, resulting in the concrete surface being wetted. Defects such as water, slurry leakage, black edge and wrong platform. Contents of the invention [0003] The object of the present invention is to provide a cast-in-place concrete fire wall formwork that does not have wet water, grout leakage, black edges and misalignment on the concrete surface at the joints of the formwork. [0004] The technical solution for realizing the present invention is that a cast-in-place fair-faced concrete fire wall formwork is composed o...
