Description

Technical Field

[0001] This utility model relates to the field of cantilever beam connection supports, and in particular to a detachable and movable connection support device for cantilever beams. Background Technology

[0002] In the construction industry, especially in the construction of high-rise buildings, cantilevered steel scaffolding is frequently used. Cantilevered steel scaffolding uses horizontal components such as I-beams to transfer the vertical load on the scaffold to the main structure. Traditionally, the operation of cantilevered steel scaffolding involves directly welding fixed lifting lugs to the cantilevered I-beams and connecting them to tie rods. Depending on different construction requirements, the original lifting lugs need to be cut or new ones re-welded, making the construction process cumbersome and complex. Furthermore, the positioning of the uprights on the cantilevered I-beams is complicated, resulting in low overall construction efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a detachable and movable connecting support device for cantilever beams that solves the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, this utility model provides a detachable movable connection support device for cantilever beams, including a cantilever I-beam and a sliding movable support movably installed on the cantilever I-beam. The sliding movable support includes transverse limiting plates located on its upper and lower sides and vertical limiting plates connected to both ends of the transverse limiting plates. Two sliders are symmetrically arranged on the lower transverse limiting plate, and a positioning threaded rod or ear plate is connected to the upper transverse limiting plate. Limiting rails are symmetrically connected to the bottom of the cantilever I-beam, and limiting grooves are provided on the limiting rails. The sliders are movably installed in the limiting grooves, and several through holes are opened on the lower transverse limiting plate.

[0005] Furthermore, threaded rods are pre-embedded in the shear wall, and the cantilevered I-beams are detachably connected to the threaded rods. A scaffolding system is set on the upper part of the cantilevered I-beams. The scaffolding system includes uprights and tie rods. The bottom end of the uprights has built-in threads so that the bottom end of the uprights can be connected to the positioning threaded rods.

[0006] Furthermore, the upper end of the tie rod is detachably connected to the threaded rod pre-embedded in the shear wall, and the lower end of the tie rod is connected to the ear plate.

[0007] Furthermore, the upright includes several grid-shaped supports, which are connected sequentially along the height direction to form the upright. At the same time, the grid-shaped support at the bottom is connected to the positioning threaded rod.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. This utility model adopts a sliding movable support. By setting a limiting rail and a limiting slider, the support can be moved flexibly according to construction requirements, and the positioning threaded rod and ear plate are precisely positioned, which improves construction efficiency.

[0010] 2. This utility model adopts a detachable mobile support, which can be quickly dismantled and reused after construction, saving costs and meeting the requirements of green environmental protection. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0017] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0018] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0019] like Figure 1-4 The present invention provides a detachable movable connection support device for cantilever beams, including a cantilever I-beam 10 and a sliding movable support movably installed on the cantilever I-beam 10. The sliding movable support includes a transverse limiting plate 8 located on its upper and lower sides and a vertical limiting plate 9 welded to both ends of the transverse limiting plate 8. Two sliders 13 are symmetrically arranged on the lower transverse limiting plate 8, and a positioning threaded rod 6 or an ear plate 7 is welded to the upper transverse limiting plate 8. A limiting rail 11 is symmetrically welded to the bottom of the cantilever I-beam 10, and a limiting groove 12 is provided on the limiting rail 11. The sliders 13 are movably installed in the limiting groove 12. Several through holes 14 are opened on the lower transverse limiting plate 8. Bolts pass through the through holes 14 to strengthen the fixation between the sliding movable support and the cantilever I-beam 10, thereby enabling the quick positioning and installation of the positioning threaded rod 6 and the ear plate 7.

[0020] The horizontal limiting plates on the upper and lower sides of the sliding movable support and the vertical limiting plates at both ends are connected to form a rectangular frame structure. This rectangular frame structure is fitted around the outer periphery of the cantilevered I-beam and can move along the length of the cantilevered I-beam.

[0021] Threaded rods are pre-embedded in the shear wall 2. The cantilevered I-beam 10 is detachably connected to the threaded rods by bolts. A scaffolding system is set on the upper part of the cantilevered I-beam 10. The scaffolding system includes uprights 4 and tie rods 5. The bottom end of the uprights 4 has internal threads so that the bottom end of the uprights 4 is connected to the positioning threaded rods 6 by thread tightening. The upper end of the tie rods 5 is detachably connected to the threaded rods pre-embedded in the shear wall 2 by bolts. The lower end of the tie rods 5 is fixedly connected to the ear plates 7 by bolts, thereby forming a safe and reliable cantilevered scaffolding system.

[0022] The upright 4 includes several grid-shaped supports, which are connected sequentially along the height direction to form the upright 4. At the same time, the grid-shaped support at the bottom is connected to the positioning threaded rod 6 to ensure the overall stability of the upright 4.

[0023] In particular, the tie rod 5 is set at an angle, so that the tie rod 5, the shear wall 2 and the cantilevered I-beam 10 form a triangular structure, which improves the stability of the cantilevered I-beam 10 and makes the cantilevered I-beam 10 simultaneously supported and limited by the pre-embedded threaded rod in the shear wall 2 and the tie rod 5.

[0024] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
