Design finalization external protective frame system used for assembly type building construction

Abstract

The invention discloses a design finalization external protective frame system used for assembly type building construction. The design finalization external protective frame system comprises a horizontal protective device, a supporting device and a vertical protective device, wherein the supporting device is supported below the horizontal protective device, and the vertical protective device is arranged on the side face of the horizontal protective device. The horizontal protective device comprises a foot plank frame body formed through welding of square steel and foot planks laid on the foot plank frame body, a row of square steel sleeve pipes are welded outside the foot plank frame body, and skirting boards are fixed between the square steel sleeve pipes. The vertical protective device comprises protective screening frame bodies formed through welding of square steel and protective screenings fixed to the protective screening frame bodies, and the bottom of the vertical square steel in the protective screening frame bodies is inserted into the square steel sleeve pipes. According to the design finalization external protective frame system used for assembly type building construction, a design finalization external protective frame is reliable in structural design, few in materials, convenient and quick to mount, low in using cost and high in safety factor, construction is conducted on the ground or in a room, the construction working face is not occupied, and construction period shortening is facilitated.

Description

technical field [0001] The present invention relates to building construction technology. Background technique [0002] For prefabricated buildings that are processed and formed by building exterior finishes and prefabricated components at one time, if the external protective frame still adopts the traditional form during construction, that is, the method of floor scaffolding or cantilevered scaffolding, there will be the following problems: 1. The construction and use of floor scaffolding The height is limited; 2. The I-beam of the cantilevered scaffold should be provided with reserved holes in the prefabricated components such as the outer wall. The reserved holes have large openings, and the later repair process is complicated, which makes it difficult to meet the quality requirements such as heat preservation and leakage; 3. Traditional steel pipe scaffolding A lot of materials are used, which is time-consuming and labor-intensive during erection, which is not conducive ...

The I-beam of the cantilevered scaffold should be provided with reserved holes in the prefabricated components such as the outer wall. The reserved holes have large openings, and the later repair process is complicated, which makes it difficult to meet the quality requirements such as heat preservation and leakage; 3. Traditional steel pipe scaffolding A lot of materials are used, which is time-consuming and labor-intensive during erection, which is not conducive to cost and construction period control, and there are many safety hazards; 4. When erecting steel pipe scaffolding, it is easy to damage the processed exterior surface of the prefabricated exterior wall, resulting in additional repair work in the later stage
