Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering, and more specifically, relates to a through-wall steel opening solid protection device and a construction method. Background Art

[0002] At present, cantilevered steel is widely used in the construction of high-rise civil engineering projects. After the main structure is completed, the cantilevered steel needs to be removed, and the through-wall holes created by the steel on the wall need to be promptly poured with concrete to seal them. When removing the steel in the masonry wall, since the wall size is fixed, vertical mortar gaps will appear in the area above the holes left by the steel. In addition, these holes are usually not equipped with lintels, and the mortar strength used in masonry is relatively low. Therefore, the layers of bricks above the holes are prone to sinking after masonry, resulting in continuous through cracks in the horizontal and vertical mortar gaps, which will have an adverse effect on the construction quality. For the exterior walls of buildings, wooden boxes are often used as protection between the steel and the exterior walls, and the wooden boards are often difficult to clean when they are removed.

[0003] During the dismantling operation of steel sections, the steel sections are often easily disturbed, which may cause damage to the wall structure around them, and then destroy the existing structure that has been completed, causing problems such as water seepage in the exterior wall and wall cracking. After the steel sections are dismantled, the reserved openings need to be sealed. The general sealing method is to set up supports at the inner and outer openings, support formwork on the inside and outside of the openings, and then pour concrete into the hole. After the concrete reaches a certain strength, the formwork is removed. This method is not only time-consuming and labor-intensive, but also has certain safety hazards and will affect the subsequent dismantling of steel sections.

[0004] In order to solve the above problems, patent document CN115126276A discloses a plugging device and construction method for cantilever I-beam reserved openings, including an outer template, an inner template, a wire and a baffle, both of which are used to plug the reserved openings, a reserved through hole is provided on the inner template, and an arc-shaped pouring port is provided on the top of the inner template, a guide groove is provided at the arc-shaped pouring port, and a fixed baffle is provided on the guide groove where the guide groove and the arc-shaped pouring port are connected; the rear end of the wire is fixed to the outer template, and the front end thereof passes through the reserved through hole on the inner template and is fastened and connected by a nut; the baffle is detachably clamped between the fixed baffle on the guide groove and the inner side of the wall, and is used to plug the arc-shaped pouring port on the inner template. The plugging device described in the present invention is used to plug the reserved opening, which has the advantage of not needing to set up an external wall bracket, and its overall structure is simple, easy to install, and part of the structure can be recycled, saving construction costs, and it is highly practical and suitable for popularization. However, it cannot be used when installing or removing steel sections, and the excess wire needs additional grinding and cleaning.

[0005] In addition, patent document CN106088447B discloses a protective brick device and construction method for cantilever scaffolding steel holes on exterior walls. When brick walls are built, U-shaped protective bricks are installed at the cantilever steel positions. When brick walls are built and cantilever steel is removed, the walls and insulation layers around the holes are effectively protected. After the cantilever steel is removed, the protective brick cover plate and the U-shaped protective brick are fastened with bolts, and the hole concrete pouring and plugging are completed indoors. This is a technology and device for quickly and effectively plugging the hole. However, this device is only applicable to brick walls, and the rigidity of the finished protective bricks is limited and cannot be adjusted according to the size of the hole. Summary of the invention

[0006] In view of the above defects or improvement needs of the prior art, the present invention provides a through-wall steel opening reinforcement and protection device and a construction method, which can reinforce the steel at various construction stages through the reinforcement unit in cooperation with the protection unit, thereby solving the problem that the steel is easily disturbed during the construction process, causing damage to the exterior wall structural materials, improving the safety of the steel during construction, and also facilitating the installation and removal of the steel, thereby improving construction efficiency. The front cover unit and the rear cover unit can automatically close under the action of gravity, thereby solving the problem that two people are required to operate inside and outside when sealing the steel opening. When sealing the opening, there is no need to use external scaffolding for formwork, and the external scaffolding of other parts can be removed normally, thereby reducing the difficulty of operation for workers, improving construction safety, saving manpower and material resources, shortening the construction period, reducing the risk of leakage at the opening, effectively reducing subsequent rework and repair, and improving the visual quality of the overall building project.
