Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a scaffolding system based on cantilevered I-beams. Background Art

[0002] Currently, the most common traditional cantilever steel beam scaffolding is that one end of the steel beam is directly installed in the main structure of the building, so that the steel beam is cantilevered outside the main structure of the building. However, after the above steel beam is used, it can only be considered as part of the building structure and cannot be disassembled.

[0003] In order to achieve disassembly, or consider disassembling and connecting the cantilever steel beam and the building beam, it is necessary to add diagonal rods to ensure the load. Relevant technologies can refer to the existing construction site conditions or the technical solutions recorded in CN 206034887 U.

[0004] However, the above design cannot achieve stable installation of the scaffolding, and additional fixing work is required between the scaffolding and the steel beams. The current practice is to use clamps to limit and lock the vertical and horizontal bars of the scaffolding and the steel beams to prevent the entire scaffolding from moving, but the above disassembly and assembly is too complicated. Utility Model Content

[0005] The purpose of the utility model is to provide a cantilever I-beam scaffold with a positioning structure, which can realize the limited installation of the vertical pole connector after the cantilever I-beam component is installed, thereby ensuring the installation of the scaffold in the later stage and avoiding the displacement of the scaffold.

[0006] The utility model is realized by the following technical solution: a cantilever I-beam scaffold with a positioning structure, characterized in that it comprises a cantilever I-beam component, a scaffold component and a diagonal tie rod;

[0007] The cantilevered I-beam components include anchor plates, I-beams, tie rod lugs, and vertical pole connectors;

[0008] The inner end of the I-beam is fixed to the front side of the anchor plate, and a plurality of through holes are opened on the anchor plate. The anchor plate is fixed to the building beam through bolts pre-buried on the building beam and nuts matched with the bolts; the tie rod hanging ear is fixed to the upper surface of the I-beam, and the vertical rod connecting piece is installed on the upper surface of the I-beam;

[0009] The scaffolding components include scaffolding uprights and scaffolding longitudinal and transverse rods, the scaffolding uprights are sleeved on the upright connectors, and the scaffolding uprights and scaffolding longitudinal and transverse rods are connected to form a scaffolding;

[0010] One end of the diagonal brace is connected to the brace hanging ear, and the other end of the diagonal brace is connected to the double-ear pull ring embedded in the building beam.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. By adding pole connectors to the cantilevered I-beam components, the scaffolding poles can be quickly positioned and installed, speeding up the construction progress.

[0013] 2. The vertical pole connector and the cantilever I-beam component are designed to be split. The position of the vertical pole connector can be adjusted according to the site conditions, thereby adjusting the position of the scaffolding component.

[0014] 3. The cantilevered I-beam structure itself, the diagonal tie rod, and the double-ear pull ring can be separated from the building body. The relevant equipment can be reused, and the construction cost can be further reduced by renting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The utility model is described in detail below with reference to the accompanying drawings:

[0020] like Figure 1-3 As shown: a cantilever I-beam scaffold with a positioning structure, comprising a cantilever I-beam member 1, a scaffolding member 2 and a diagonal tie rod 3;

[0021] The cantilevered I-beam member 1 comprises an anchor plate 11, an I-beam 12, a tie rod hanger 13 and a vertical rod connector 14;

[0022] The inner end of the I-beam 12 is fixed to the front side of the anchor plate 11. A plurality of through holes are opened on the anchor plate 11. The anchor plate 11 is fixed to the building beam 9 by bolts 91 pre-buried on the building beam 9 and nuts matched with the bolts 91. The tie rod hanging ear 13 is fixed to the upper surface of the I-beam 12, and the vertical rod connector 14 is installed on the upper surface of the I-beam 12.

[0023] The scaffolding member 2 includes a scaffolding upright pole 21 and a scaffolding longitudinal and transverse pole 22. The scaffolding upright pole 21 is sleeved on the upright pole connector 14. The scaffolding upright pole 21 and the scaffolding longitudinal and transverse pole 22 are connected to form a scaffolding.

[0024] One end of the inclined brace 3 is connected to the brace hanging ear 13 , and the other end of the inclined brace 3 is connected to a double-ear pull ring 92 pre-buried on the building beam 9 .

[0025] The I-beam 12 itself is used as a cantilever beam. The I-beam 12 and the anchor plate 11 are welded to each other. The anchor plate 11 is fixed to the bolts 91 embedded in the building beam 9 by nuts, thereby achieving the position of the I-beam 12. Here, the main purpose is to achieve the rapid positioning and connection of the scaffolding uprights 21 by setting the upright connectors 14 on the I-beam 12.

[0026] It should be noted that after the installation of the I-beam 12 is completed, it is necessary to connect the diagonal brace 3 and adjust the diagonal brace 3. Of course, the specific adjustment method and purpose are all existing technologies, so they will not be described in detail.

[0027] A reinforcing rib 4 is provided between the inner bottom of the I-beam 12 and the surface of the anchor plate 11, thereby improving the connection strength between the I-beam and the anchor plate 11.

[0028] The vertical pole connector 14 is a mobile positioning pile, which includes an upper clamping plate 141, a lower clamping plate 142, a locking member 143, and a vertical pole connecting rod 144. The connecting rod is fixed to the surface of the upper clamping plate 141. The upper and lower clamping plates 141 and 142 are connected by the locking member 143, and the upper and lower clamping plates 141 and 142 are clamped to the upper cross plate of the I-beam 12. By locking and releasing the locking member 143, the mobile positioning pile can be disassembled and moved, and the position movement can be achieved in the left and right directions and the front and back directions.

[0029] The locking member 143 of the movable positioning pile can be a common screw and adjusting nut. Other building types also adopt a locking structure.

[0030] Generally speaking, the anchor plate 11 is a flat plate or a corner connecting plate.

[0031] All components of the present invention can be obtained by renting. When the building is used, it is necessary to embed M20 high-strength bolts and screw in double-ear pull rings on the beams corresponding to the area where the scaffolding is required, install mobile positioning piles on the I-beams, and then install the anchor plates in place and install the diagonal rods; consider whether to adjust the position of the mobile positioning piles according to the site needs. If no adjustment is required, install the scaffolding uprights 21 and the scaffolding vertical and horizontal bars 22.

[0032] If disassembly is required later, proceed in the reverse order of the above steps.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
