Description

Building construction pours support frame with board of cornicing

Technical Field

The invention relates to the technical field of building construction, in particular to a cornice plate pouring support frame for building construction.

Background

The cornice board refers to a part of a roof or a floor, which is taken out of an outer wall, the width of the cornice board is generally not more than 50 cm, the cornice board has the function of preventing rainwater on the roof from flowing backwards to a wall body when being discharged downwards, and the cornice board can be divided into organized drainage and unorganized drainage according to a rainwater discharge mode. The eaves that drain organically form gutters, while the eaves that drain unorganically do not. When the cornice plate is poured, a mold is supported below the cornice plate, and the mold is generally fixed by a support frame. For improving drainage effect, the board of cornicing generally can pour into and have certain inclination, and the board mould of cornicing also can form certain inclination with the horizontal plane, and the below problem at least exists when supporting the board of cornicing that has certain inclination: firstly, a common support frame is mainly used for supporting a horizontal mold, when the support frame supports a cornice board mold with an inclined angle, a support plate at the top of the support frame cannot be subjected to angle adjustment according to the mold angle, so that the whole support is not stable enough, the phenomena of mold opening, mold cracking and mold reversing can occur in the supporting process, and the danger in the construction process is increased; secondly, when the support frame supports the mould of the cornice plate with an angle, a device for ensuring the stability of the inclination angle of the support plate above the support frame is lacked, and the inclination angle of the support plate can be increased when the support plate continuously bears the long-time heavy pressing of the cornice plate, so that the inclination angle of the mould and the cornice plate after pouring is changed, and the pouring requirement cannot be met; each support frame supports the eaves board again mainly being of solitary face degree face, lacks the connection mounting between each support frame, can not make all support frames knot as an organic whole, is unfavorable for the stability of support frame. Consequently need a building construction with board of cornicing and pour support frame to solve the support frame and can not adjust the support angle according to supporting the mould, lack when support frame inclined support and guarantee support angle stability device, poor stability's problem when support frame supports alone.
