A casting method and mold for cast-in-place beams for doors and windows

Abstract

The invention discloses A casting method for cast-in-situ beams of doors and windows, the method is realized by a single mold consisting of side forms, bottom forms, movable and telescopic vertical braces and diagonal braces. It is connected with the support bracket by a hinge or a pin shaft. The two single molds are symmetrically installed on both sides of the door opening, and the bottom mold is installed to the specified height through the telescopic device on the vertical support bracket. The bottom mold on the two single molds Connect and fix through locks and wrenches, fix the vertical support bracket and support the diagonal support bracket, set up the side forms on both sides of the bottom form and fix the two side forms through movable clamps. After the reinforced concrete construction is completed and the demolition strength is reached Finally, remove the movable clamp, loosen the wrench, and then slowly shrink the vertical support bracket through the telescopic device, so as to realize the purpose of automatic form removal. Its construction process is simple, and it can greatly improve the work of form support while ensuring the quality of the concrete lintel. efficiency.

Description

[0001] Technical Description [0002] The invention relates to a method for pouring cast-in-place beams of doors and windows and a mold, belonging to the technical field of building construction. Background technique [0003] With the rapid development of the national economy, urban construction is also advancing by leaps and bounds, and various large-scale construction projects are blooming everywhere. As a very important secondary structure construction process, cast-in-place concrete lintels, up to now, the commonly used formwork support methods are still very backward steel pipe fasteners or wooden square supports, and the erection process is cumbersome. It is particularly time-consuming and labor-intensive, the material reuse rate is extremely low, and because of the technical differences of workers, the forming quality of the lintel is often not guaranteed, which can no longer meet the increasingly higher progress and quality requirements of various current engineering p...
