Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to an I-beam installation structure for a cantilever scaffolding. 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 process of cantilever scaffolding using I-beams as supports is currently more frequently used. In this process, 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 construction penetrating the floor slab will also have an impact on the floor slab. Second, the U-shaped anchor ring method is mostly one-time use, that is, after the scaffolding is completed, the pre-embedded structure cannot be taken out and reused, resulting in 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 present technical solution forms a cavity structure for supporting and limiting the I-beam by installing a base plate and a vertical upright on the floor plate, and cooperating 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 method of pre-embedded installation with a U-shaped anchor ring, the present technical solution does not require penetration of the floor plate, thereby 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.

[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 horizontal support plate assembly installed on the vertical upright plate, and a vertical limiting assembly installed in conjunction with the vertical upright plate. The vertical limiting assembly cooperates with the horizontal 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 provided 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 limiting cover plate protrudes downward to form a cover plate boss, and the limiting locking rod passes through the cover plate boss and extends downward to cooperate with the installation of the horizontal support plate assembly.

[0009] Furthermore, the transverse support plate assembly includes a transverse support plate fixedly installed in conjunction with the vertical upright plate, a locking nut arranged at the bottom of the transverse support plate, and a support plate rib 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 to the I-beam.

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

[0011] Furthermore, the locking wing is bent downward and inward to form a cover plate limiting folding arm portion, and the end portion of the vertical stand 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 base plate is provided with base plate mounting holes for connection and installation with the floor plate.

[0013] The beneficial effects of the utility model are:

[0014] 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 conjunction with a vertical limit assembly.

[0020] In this embodiment, the vertical limit assembly includes a limit cover plate 12, a limit locking rod 11 disposed on the limit cover plate 12, and a locking wing plate 14 formed at the end of the limit cover plate; the locking wing plate 14 is plugged and installed with the vertical upright plate 7. There are two vertical upright plates 7, which are arranged parallel to each other on the base plate 5. The vertical upright plates and the base plate 5 can be integrally formed to enhance product strength. The two vertical upright plates, together with the limit cover plate 12, form a cavity structure for mounting the I-beam.

[0021] In this embodiment, the center portion of the position-limiting cover plate 12 protrudes downward to form a cover plate boss 10. The position-limiting locking rod 11 passes through the cover plate boss 10 and extends downward to engage the transverse support plate assembly for installation. The downward protrusion of the center portion of the position-limiting cover plate 12 to form a boss facilitates structural strength at the installation site. The position-limiting locking rod 11 can be a locking screw, with its lower end passing through the cover plate boss 10 and then engaging the transverse support plate assembly to securely mount against the I-beam.

[0022] In this embodiment, the transverse support plate assembly includes a transverse support plate 8 fixedly mounted to the vertical upright plate 7, a locking nut 9 disposed at the bottom of the transverse support plate, and support plate ribs disposed between the transverse support plate 8 and the vertical upright plate 7.

The transverse support plate 8 is disposed between the two vertical upright plates and is parallel to the bottom plate 5. The support plate ribs are disposed between the transverse support plate 8 and the vertical upright plate 7 to ensure that the structural performance is met.

[0023] In this embodiment, the limiting locking rods 11 are multiple and are arranged parallel to each other on the limiting cover plate, and the locking nuts 9 are multiple and are evenly distributed on the transverse support plate 8. Both the locking screws and the locking nuts are multiple and are arranged in a one-to-one correspondence, facilitating positioning and installation at multiple points.

[0024] In this embodiment, the locking wing plate 14 is bent downward and inward to form a cover plate limit arm portion, and the end of the vertical stand is bent outward and downward to form a vertical plate limit arm portion 13. The cover plate limit arm portion and the vertical plate limit arm portion engage with each other. Figure 2 As described above, the two continuously bent arm portions cooperate to form a mutually interlocking structure, and in conjunction with the locking rod structure, the overall structure further enhances the limiting effect on the I-beam.

[0025] In this embodiment, the base plate 5 is provided with base plate mounting holes 4 for connection and installation with the floor plate. The base plate 5 is provided with multiple base plate mounting holes, and multiple mounting positions ensure its connection performance. The upper surface of the limit cover plate 12 is provided with transverse reinforcement ribs 15 and longitudinal reinforcement ribs 16 to enhance structural strength.

[0026] A construction method for cantilever scaffolding I-beams comprises the following steps:

[0027] S1: After the concrete pouring of the structural floor slab 3 is completed, the installation position of the I-beam is determined. The position where the I-beam needs to be locked and installed is confirmed based on the cantilever length of the I-beam, and the position is marked. At the position where the scaffolding needs to be erected on the floor slab 3, the position of the I-beam is determined and marked.

[0028] S2: Use multiple expansion bolts to fix the bottom plate 5 to the floor structure to ensure the stability of the bottom plate and vertical plates. Figure 1 As shown, multiple expansion bolts are used to stably install the structure. Pads 1 are directly provided between the cantilever end A and the base plate. Multiple locking structures can be provided at the locking end B according to construction requirements to ensure the stability of the I-beam.

[0029] S3: The I-beam passes through the vertical plate and extends to the desired cantilever position. The limiting cover plate is inserted so that the limiting folding arm of the cover plate and the limiting folding arm of the vertical plate form a mutual engagement. The I-beam is passed through the cavity structure and the limiting cover plate is installed for preliminary positioning and installation.

[0030] 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, install the limit locking rod so that its end passes through the locking nut and is tightened against the surface of the I-beam; adjust the installation position of the limit cover plate and lock the locking rod to complete the construction and installation. When the scaffolding construction is completed, the entire structure can be dismantled and recycled.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
