Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to an I-beam installation structure of a cantilever scaffolding and a construction method. Background Art

[0002] Cantilever scaffolding is a simple facility used in construction. It is divided into two types: one cantilever per floor and multi-layer cantilever. Cantilever scaffolding is widely used in cantilever structure construction.

[0003] The construction technology of cantilever scaffolding using I-beams as supports is currently used more frequently. In this technology, the fixed end (the fixed end of the I-beam) is fixed with a U-shaped anchor ring. This form has many disadvantages. First, the use of U-shaped anchor rings requires pre-embedded construction, and the pre-embedded penetration of the floor slab will also have an impact on the floor slab. Second, the U-shaped anchor ring method is mostly used once, that is, after the scaffolding is completed, the embedded structure cannot be taken out and reused, resulting in a waste of production materials.

[0004] Therefore, in order to solve the above problems, a cantilever scaffolding I-beam installation structure is needed to solve the above problems. Summary of the invention

[0005] In view of this, the cantilever scaffolding I-beam installation structure of the technical solution, by installing the base plate and the vertical upright plate on the floor plate, cooperates with the vertical limit assembly, to form a cavity structure for supporting and limiting the I-beam, and the I-beam is pressed and limited by the vertical limit assembly, so that the overall structure is installed stably and reliably. Compared with the traditional method of pre-embedded installation with U-shaped anchor rings, the technical solution does not need to penetrate the floor plate, thereby avoiding the problem of water leakage of the floor plate in the later stage. At the same time, the scaffolding is easy to dismantle and recycle after use.

[0006] A cantilever scaffolding I-beam installation structure includes a base plate arranged on a floor plate, a vertical upright plate arranged on the base plate, a transverse support plate assembly installed on the vertical upright plate, and a vertical limit assembly installed in conjunction with the vertical upright plate. The vertical limit assembly cooperates with the transverse support plate assembly to limit and tighten the I-beam.

[0007] Furthermore, the vertical limiting assembly includes a limiting cover plate, a limiting locking rod disposed on the limiting cover plate, and a locking wing plate formed at the end of the limiting cover plate; the locking wing plate is plugged and installed in conjunction with the vertical stand plate.

[0008] Furthermore, the middle portion of the limit cover plate protrudes downward to form a cover plate boss, and the limit locking rod passes through the cover plate boss and extends downward to cooperate with the installation of the transverse support plate assembly.

[0009] Furthermore, the transverse support plate assembly includes a transverse support plate fixedly installed in cooperation with the vertical upright plate, a locking nut arranged at the bottom of the transverse support plate, and a support plate rib plate arranged between the transverse support plate and the vertical upright plate. The lower end of the limit locking rod passes through the transverse support plate and the locking nut and the end is tightened against the I-beam.

[0010] Furthermore, the limiting locking rods are multiple and are arranged parallel to each other on the limiting cover plate, and the locking nuts are multiple and are evenly distributed on the transverse support plate.

[0011] Furthermore, the locking wing plate is bent downward and inward to form a cover plate limiting folding arm portion, and the end portion of the vertical upright plate is bent outward and downward to form a vertical plate limiting folding arm portion, and the cover plate limiting folding arm portion cooperates with the vertical plate limiting folding arm portion to engage with each other.

[0012] Furthermore, the bottom plate is provided with a bottom plate installation hole for connecting and installing with the floor plate.

[0013] A construction method for cantilever scaffolding I-beams comprises the following steps:

[0014] S1: After the concrete pouring of the structural floor slab is completed, the installation position of the I-beam is determined. According to the cantilever length of the I-beam, the position where the I-beam needs to be locked and installed is confirmed, and the position is marked;

[0015] S2: Use multiple expansion bolts to fix the bottom plate to the floor structure to ensure the stability of the bottom plate and vertical panels;

[0016] S3: The I-beam passes through the vertical plate and extends to the position required for cantilevering, and the limiting cover plate is inserted so that the limiting folding arm part of the cover plate and the limiting folding arm part of the vertical plate form a mutual engagement;

[0017] S4: Adjust the horizontal installation position of the limit cover plate so that the installation hole on the cover plate boss is aligned with the locking nut, and install the limit locking rod so that its end passes through the locking nut and is tightened against the surface of the I-beam.

[0018] The beneficial effects of the present invention are:

[0019] The cantilever scaffolding I-beam installation structure of the present technical solution forms a cavity structure for supporting and limiting the I-beam by installing a base plate and a vertical upright plate on the floor plate in cooperation with a vertical limit assembly. The I-beam is pressed and limited by the vertical limit assembly, so that the overall structure is installed stably and reliably. Compared with the traditional installation method using a U-shaped anchor ring for pre-embedded installation, the present technical solution does not need to penetrate the floor plate, thus avoiding water leakage of the floor plate in the later stage. At the same time, the scaffolding is easy to dismantle and recycle after use. BRIEF DESCRIPTION OF THE DRAWINGS
