Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to an inward-retracted overhead climbing frame lifting system. Background Art

[0002] With the increasing number of super high-rise buildings, attached climbing scaffolding is also widely used. However, architects are not satisfied with the conventional architectural style. The design of overhead mezzanine structures is increasing, which makes it impossible to attach the climbing frame to the structure in a conventional way, and a temporary attachment structure needs to be added.

[0003] The prior art patent CN 209907895U "A climbing frame attachment device" requires the use of the original structural shear wall for attachment, which mainly solves the problem that the design strength of the shear wall cannot meet the climbing and use requirements of the climbing frame. However, the overhead layer and the split-level structure basically have no external walls to provide an attachment structure for the climbing frame, so this prior art cannot be applied.

[0004] Therefore, how to create a new inward-retracted overhead climbing frame lifting system is one of the important current research and development topics. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an inward-retracted overhead climbing frame lifting system, which utilizes steel columns and extended wall-mounted supports to provide temporary attachment points for the climbing frame, and can adjust the outward extension distance of the extended wall-mounted supports according to the inward retreat distance of the overhead layer, thereby facilitating construction and being revolving for use, thereby overcoming the shortcomings of the prior art.

[0006] In order to solve the above-mentioned technical problems, the utility model provides an inward-retracted overhead climbing frame lifting system, including a steel column, an elongated wall-mounted support and an adjustable pull rod. The steel column is vertically arranged at the edge of the inward-retracted overhead layer, the elongated wall-mounted support is horizontally arranged, one end is connected to the steel column by bolts, and the other end is cantilevered out of the layer, and the cantilevered end is used to connect with the climbing frame. The adjustable pull rod is obliquely connected between the cantilevered end of the elongated wall-mounted support and the steel column, changes the connection position of the elongated wall-mounted support and the steel column, and adjusts the length of the pull rod, so as to adjust the distance that the elongated wall-mounted support extends out of the layer.

[0007] As an improvement of the utility model, the adjusting pull rod is also connected obliquely between the steel column and the inward-recessed overhead floor slab to improve the stability of the steel column.

[0008] Furthermore, the steel column includes angle steel, tie bars, support fixing steel plates, adjustable tie rod lifting ears and lifting ear fixing plates. Four angle steels are vertically arranged to constitute the four corners of the steel column. Several tie bars are horizontally welded at equal intervals between the four angle steels. The support fixing steel plate is welded and fixed to the tie bars for connection with the extended wall-mounted support. The lifting ear fixing plate is arranged on the inner and outer sides of the steel column at the same height and are respectively welded and fixed to the angle steel and tie bars. The adjustable tie rod lifting ears are welded to the lifting ear fixing plates for connecting the adjustable tie rods.

[0009] Furthermore, the number of the ear fixing plates and the adjusting rod ear is four, which are respectively arranged on the inner and outer sides of the middle part of the steel column and the inner and outer sides of the top.

[0010] Furthermore, the bottom of the steel column is fixed to the inward-set overhead layer through a column embedded part, and the column embedded part includes a steel plate and an anchor bar. The steel plate and the anchor bar are welded and fixed by a perforated plug welding process. The anchor bar is vertically embedded in the inward-set overhead layer floor slab, the steel plate is exposed, and the bottom of the steel column is welded and fixed to the steel plate.

[0011] Furthermore, the extended wall-mounted support includes a channel steel, a tie plate and a tie rod ear. Two channel steels are of equal length and arranged in parallel. Several tie plates are welded between the two channel steels. The channel steel and the tie plates together constitute the main body of the extended wall-mounted support. A tie rod ear is welded and fixed near the cantilevered end of the extended wall-mounted support, and the tie rod ear extends vertically upward from the extended wall-mounted support.

[0012] Furthermore, the elongated wall-mounted support also includes a top support and a fall arrester, and the top support and the fall arrester are both installed at the cantilevered end of the elongated wall-mounted support.

[0013] Furthermore, the adjusting pull rod comprises an ear plate, a screw rod, a seamless steel pipe, an adjusting handle, a perforated head plate and a positive and negative thread nut;

[0014] The perforated head plate is welded to the two ends of the seamless steel pipe, a hole is opened in the center of the perforated head plate, and positive and negative thread nuts are welded and fixed on the outside of the hole. The thread rotation directions of the positive and negative thread nuts at the two ends of the seamless steel pipe are opposite. The two screws are respectively screwed into the positive and negative thread nuts from the two ends and extended into the seamless steel pipe. The outer ends of the screws are welded and fixed to the roots of the lifting ears. The adjustment handle is welded to the middle of the seamless steel pipe and is perpendicular to the axis of the seamless steel pipe. The seamless steel pipe is rotated by adjusting the handle to make the two lifting ears move toward or away from each other synchronously to change the overall length of the adjustment rod.

[0015] Furthermore, the adjusting pull rod is fixed to the inward-retracted elevated floor slab by a pull rod embedded part, and the pull rod embedded part includes a through-wall bolt and a lug plate, and the lug plate is arranged above the inward-retracted elevated floor slab, and the through-wall bolt vertically passes through the lug plate and the inward-retracted elevated floor slab, and is pulled and locked on the upper and lower sides by nuts and pads.

[0016] After adopting such a design, the utility model has at least the following advantages:

[0017] 1. The extended wall-mounted support is connected and fixed to the steel column by bolts, providing a temporary attachment point for the climbing frame. The extension distance of the extended wall-mounted support can be adjusted by changing the position of the connection point between the extended wall-mounted support and the steel column, as well as changing the length of the adjustment rod.
