Support formwork device and construction method for one-step formed flange concrete in kitchens and toilets

Abstract

A support formwork device and a construction method for one-step formed flange concrete in kitchens and toilets belong to the technical filed of disposable support formworks for building construction and construction using the formworks. The support formwork device is formed by an outer steel formwork (1), an inner steel formwork (2), a square tube (3) with dimension of 30 x 3, a phi 10 bolt (4), a hanging bracket (5) made of a square tube with dimension of 50 x 4, right-angle triangular steel plates (6) with dimension of 2000 x 3, a phi 10 formwork supporting seat (7), an angle steel (8) with dimension of 40 x 30 and a door opening reserving device (9). The construction method is that the formwork supporting seat (7) is arranged on a plate formwork where a cement mortar pad is firstly placed, the outer steel formwork (1) and the inner steel formwork (2) are fixed through the square tube (3) and then arranged on the formwork supporting seat, and the door opening reserving device (9) is placed on the outer steel formwork (1) and the inner steel formwork (2). The steel plates (6) are welded to four corners of the inner steel formwork (2), and the hanging bracket (5) and the outer steel formwork are fixed by the bolt (4). The device has simple construction, guarantees one-step forming and accurate dimension of flanges in the kitchens and the toilets, and resolves the problems of leakage, large dimension error and the like in the kitchens and the toilets.

Description

1. Technical field [0001] The utility model relates to a one-time molding formwork support device and a construction method for flanging concrete in a kitchen and bathroom, and belongs to the technical field of one-time formwork support in building construction. 2. Background technology [0002] At present, most projects use wooden formwork secondary formwork in the flanging construction of the kitchen and bathroom to complete the flanging structure required by the design. [0003] Concrete flanging is generally used to meet the functional requirements of the building. It is a treatment for openings or edges to prevent rainwater from leaking in or to set a cover on the upper part. The flanging is to make a concrete member around the opening with a certain thickness and a certain height and connected with the surrounding concrete slab. The kitchen and bathroom and the floor of the floor with waterproof requirements must be provided with flanging concrete. The traditional woo...

AI Technical Summary

Problems solved by technology

This construction method suspends the bottom of the flanging formwork and communicates with the floor concrete, so that the formed flanging is integrated with the floor slab. However, the operation process is relatively complicated, and it is difficult to control the stability of the turning over formwork during concrete pouring, which is easy to change position. or expansion mold

Most of the flanging needs to be manually repaired after pouring with hanging formwork, which not only wastes man-hours but also affects the appearance, so it is rarely used in actual construction.
