Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a multi-flight staircase formwork supporting device. Background Art

[0002] Stairs are composed of continuous steps, rest platforms and enclosure components. They can be divided into single-tread stairs, double-tread stairs and multi-tread stairs according to the steps. In current construction, it is common to set up formwork directly on the concrete floor or hard floor. This method is suitable for the erection of floor slab formwork, but when it is applied to the erection of multi-tread staircases and rest platform formwork with high floor height, this method is not conducive to the subsequent removal of the formwork, because the formwork for multi-tread staircases and rest platforms is set up before the concrete is poured. After the concrete is poured, there is an embedded part between the bottom of the formwork and the stair slab concrete, which can only be removed by cutting. This method seriously affects the removal efficiency. Cutting and removing the formwork will damage the complete formwork uprights, resulting in material loss and increased construction costs.

[0036] Example:

[0037] This embodiment provides a multi-flight staircase formwork support device, which is used to solve the technical problem that the multi-flight staircase formwork support device in the prior art is difficult to dismantle. The multi-flight staircase formwork support device includes a base 1, a connecting rod 2, a support pipe 3 and a limiter, wherein:

[0038] The base 1 is a structural component made of metal material.

[0039] The connecting rod 2 is detachably mounted on the base 1, and the axis of the connecting rod 2 and the base 1 are perpendicular to each other. The detachably connected connecting rod 2 and the base 1 facilitates separation of the connecting rod 2 and the base 1 without cutting.

[0040] One end of the support tube 3 is slidably installed on the connecting rod 2 along the axial direction of the connecting rod 2, and the axis of the support tube 3 and the axis of the connecting rod 2 are located on the same straight line. Optionally, the support tube 3 is slidably sleeved outside the connecting rod 2, and there is a clearance fit between the support tube 3 and the connecting rod 2. In this way, by slidingly installing the support tube 3, it is convenient to adjust the length of the connecting rod 2 extending out of the support tube 3 according to the construction conditions.

[0041] The limiter is installed between the support tube 3 and the connecting rod 2. The limiter is used to fix the support tube 3. After adjusting the length of the connecting rod 2 extending out of the support tube 3, the limiter is installed between the support tube 3 and the connecting rod 2 to prevent the support tube 3 from sliding on the connecting rod 2.

[0042] In working state, the base 1 is installed at the top of the n-th stair template, and the other end of the support tube 3 abuts against the bottom end of the (n+1)-th stair template, where n is a positive integer greater than 1.

[0043] Through the above structure, after the stair formwork is supported, when it is necessary to cast multiple flights of stairs, the base 1 is first fixed to the top of the nth flight of stairs formwork to be cast, and then the relative distance between the support tube 3 and the connecting rod 2 is determined according to the building elevation information, so that the end of the support tube 3 away from the connecting rod 2 abuts against the bottom end of the n+1th flight of stairs formwork, and finally the limiter is installed between the connecting rod 2 and the support tube 3 to prevent the support tube 3 from moving along the axis of the connecting rod 2 toward the direction close to the nth flight of stairs formwork. In this way, the multi-flight stair formwork support device provided by the utility model is supported between the nth and n+1th flights of stairs, and the support device is installed according to the building elevation information. According to the above method, multiple multi-flight staircase formwork support devices provided by the utility model are installed between the multi-flight stairs. After the support device is installed, the multi-flight stairs are poured at the same time. After the concrete pouring is completed, the connecting rod 2 detachably installed with the base 1 can be removed and separated from the base 1. In this way, the base 1 can be separated from the support device without cutting, and finally a new base 1 can be installed.

Specifically, the inner diameter of the circular ring 5 is equal to the outer diameter of the support tube 3. The circular ring 5 is welded to the support tube 3. The connection between the circular ring 5 and the support tube 3 is more stable by fixing the circular ring 5. The setting of the second through hole 51 makes it easier to connect the circular ring 5 to the stair support.

[0053] Optionally, there are multiple second through holes 51, and the multiple second through holes 51 are evenly distributed along the circumferential direction of the ring 5. In this way, the connection between the ring 5 and the stair support is more stable through the provision of the multiple second through holes 51.

[0054] Optionally, there are multiple rings 5, and the multiple rings 5 ​​are evenly distributed on the support tube 3 along the axial direction of the support tube 3. Through the arrangement of multiple rings 5, the multi-run stair formwork support device provided by the embodiment of the utility model can be more stably installed on the stair formwork.
