Description

Technical Field

[0001] The utility model relates to the technical field of supporting structures for pouring steel bar layers, in particular to a device for supporting a super high-rise staircase platform. Background Art

[0002] In the prior art, during the binding of the steel bars of the stair platform, concrete pads are generally used at the bottom to pad the bottom steel bars of the platform to ensure the thickness of the protective layer. Steel bar stools or pads are used in the middle of the steel bar layer to support the double-layer steel bars of the platform to ensure its thickness and position, such as the technical solution of announcement number CN215211916U; before pouring concrete on the wall column beam slab, the "earth"-shaped steel bars are nailed to the bottom formwork or tied to the bottom steel bars and nailed to the formwork to ensure its stability. The above construction method has certain limitations: (1) The diameter of the platform steel bars is small and easy to deform and shift; the thickness of the platform section is difficult to control, the accuracy is low, and the adjustment construction is difficult; (2) The support pipe of the floor slab above the stair turning platform is fixed to the steel bar layer with nails. The nails are easy to rust during the pouring process. The support pipe is directly inserted into the steel bar layer of the stair turning platform. In the later pouring, it is firmly buried in the concrete of the stair turning platform and is not easy to remove. Violent removal will seriously damage the integrity of the concrete layer of the turning platform. Utility Model Content

[0003] The utility model provides a device for supporting a super high-rise staircase platform, aiming to solve the technical problems of controlling the thickness of the super high-rise staircase platform section, the stability of the upper floor support pipe and the disassembly.

[0005] Compared with the prior art, the beneficial effects of the utility model are: the utility model adjusts the cross-sectional thickness of the stair turning platform through a threaded bracket, and at the same time the upper bracket supports the bracket pipe to provide support for the formwork of the floor slab above the turning platform. After the concrete of the stair turning platform is poured, the bracket pipe is easy to disassemble, and the degree of damage caused to the concrete layer of the stair turning platform is very small.

[0006] The preferred embodiment of the present utility model is:

[0007] The bracket includes an annular outer frame ring, connecting ribs and an annular inner frame ring. The inner wall of the annular inner frame ring is provided with an internal thread, and the outer wall of the support rod is provided with a matching external thread. The annular inner frame ring is threadedly connected to the support rod so that the height of the annular inner frame ring on the support rod can be adjusted; the annular inner frame ring is connected to the annular outer frame ring through connecting ribs, and the connecting ribs and the annular outer frame ring play the role of supporting the upper steel bars and bracket pipes of the stair platform.

[0008] Anchor bars are fixed on the back of the anchor plate and embedded in the concrete pad, increasing the bond strength between the anchor plate and the precast concrete pad to ensure a firm connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.

[0013] like Figure 1 As shown, the utility model provides a device for supporting a super high-rise staircase platform, including a concrete pad 1, an anchor plate 2, a support rod 4 and a bracket 5; threaded steel bars are evenly welded on the back of the anchor plate 2 as anchor bars 3, and the anchor bars 3 are vertically embedded in the concrete pad 1 to form a whole with it, thereby increasing the bond strength between the anchor plate 2 and the precast concrete pad 1 and ensuring a firm connection. The precast concrete pad 1 is placed at the bottom of the bottom steel bar 6 as a bottom steel bar support to ensure the thickness of the protective layer. A screw rod is welded on the upper surface of the anchor plate 2 as the support rod 4, and a threaded bracket 5 is installed in the middle of the support rod 4.

[0014] like Figure 2As shown, the bracket 5 includes an annular outer frame ring 51, connecting ribs 52 and an annular inner frame ring 53. The inner wall of the annular inner frame ring 53 is provided with an internal thread matching the thread on the support rod 4. The annular inner frame ring 53 is connected to the annular outer frame ring 51 through a plurality of connecting ribs 52. The annular outer frame ring 51 and the connecting ribs 52 mainly support the upper steel bars 7 and the bracket pipe 8 of the stair platform. Nuts are preferably used as the annular inner frame ring 53 at the construction site. The function of the bracket 5 is to adjust the cross-sectional thickness of the platform steel bars and prevent them from deformation and displacement. If they are stepped on or deviated during the construction process, the height of the bracket 5 can be adjusted by twisting the annular inner frame ring 53.

[0015] The upper end of the support rod 4 is covered with a support pipe 8, which supports the floor template above the stair turning platform. The bottom steel bar 6 of the stair platform is supported on the anchor plate 2, and the upper steel bar 7 of the stair platform is placed on the bracket 5. Before pouring the concrete of the wall column beam slab, the upper floor template is completed, and the support pipe 8 is placed on the support rod 4 to ensure the stability of the support. No nails are needed to fix it, which avoids the problem of rust. The overlap distance between the support rod 4 and the stair turning platform is small. When disassembling, it can be removed by gently knocking, and the concrete surface layer of the stair turning platform will not be deeply or extensively damaged.

[0016] The materials of this device can be found everywhere on the construction site, and it is easy to make and has low cost. It can not only ensure the thickness of the protective layer of the steel bars at the bottom of the platform, but also be used as a horse stool for double-layer steel bars. The cross-sectional thickness of the stair turning platform is ensured by the adjustment function of the bracket 5. It can also serve as the footing force point of the bottom support device of the bracket pipe 8 to ensure the stability of the upper formwork frame. It is suitable for various plate thicknesses, easy and quick to adjust, and has a wide range of applications.

[0017] Finally, it should be noted that the above-listed examples are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and modifications fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
