Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a foot support device for the vertical rod of a stair transfer rest platform. Background Art

[0002] In the construction of cast-in-place stairs, the feet of the inner support vertical rods at the rest platform in the middle of the stairs often need to be supported by cushion blocks or steel bar brackets, so as to separate the thickness range of the cast-in-place rest platform slab from the vertical rods. For example, if cushion blocks are used to support the vertical rods, a large amount of cushion blocks are required, and they cannot be cast integrally with the cast-in-place rest platform, and the strength of the cushion blocks cannot be guaranteed; if a "T"-shaped steel bar bracket is used, the diameter of the required steel bars is not less than 16, and certain technical requirements are imposed on the welders during the welding of the steel bars. If the welding is not firm, instability may occur during the pouring process. Moreover, after being cast integrally with the rest platform, the steel bars protruding from the concrete surface need to be cut off, resulting in waste of steel bars, and there are safety hazards during the cutting process of the steel bars. The overall support stability, axial force and other conditions are poor. Content of the Utility Model

A number of positioning holes are drilled through the wall of the main foot support member. An isolation sleeve is sleeved outside one end of the main foot support member close to the bottom. The isolation sleeve and the main foot support member are detachably arranged. One end of the isolation sleeve close to the bottom of the main foot support member is sealed. The length of the isolation sleeve is greater than the thickness of the cast-in-place slab of the stair transfer rest platform; the accessory is a positioning tube matching the size of the positioning hole, and the positioning tube can pass through the positioning hole to provide support force for the vertical rod.

[0006] The above-mentioned main foot support member is a galvanized steel pipe.

[0007] A main member bottom plate is welded to the bottom of the above-mentioned main foot support member, and the main member bottom plate is used to increase the stress area.

[0016] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1 , the utility model provides a technical solution:

[0018] A staircase transfer rest platform upright foot support device includes a foot support main component 1, the foot support main component 1 is a circular steel pipe, a plurality of positioning holes 2 are opened through the wall of the foot support main component 1, and a main component bottom plate 4 is welded to the bottom to increase the force-bearing area, and an isolation sleeve 3 is sleeved on the outside of the foot support main component 1 near the bottom end, and the length of the isolation sleeve 3 is greater than the thickness of the cast-in-place slab of the staircase transfer rest platform. The isolation sleeve 3 and the foot support main component 1 are detachable, and the isolation sleeve 3 is made of plastic. A fixing plate 5 is fixed to the bottom of the isolation sleeve 3, and the fixing plate 5 seals the bottom of the isolation sleeve 3, and a fixing nail 6 is provided on the fixing plate 5. The upright foot support device is equipped with a positioning tube 7 that matches the size of the positioning hole 2, and the positioning tube 7 can pass through the positioning hole 2 opened on the wall of the foot support main component 1.

[0019] As a specific embodiment, the main foot support member 1 is made of a galvanized steel pipe with a diameter of 30, a wall thickness of 3.0 mm, and a length of 300 mm. Through holes are drilled through the steel pipe, with a hole diameter of 18 mm and a hole spacing of 30 mm, facilitating the insertion of a positioning pipe 7 with a diameter of 16. The positioning pipe 7 is mainly used to provide support force for the vertical rod 8. A plastic isolation sleeve 3 is sleeved outside the main foot support member 1. The inner diameter of the isolation sleeve 3 is 36 mm and the wall thickness is 2.0 mm. Two positioning rings are provided at the foot to facilitate the fixation of the sleeve using nails or screws. The length of the plastic isolation sleeve 3 is 200 mm and is greater than the thickness of the cast-in-place slab by 100 mm, preventing grout from entering the isolation sleeve 3 and making it difficult to remove and reuse the foot support device for the vertical rod.

[0020] In this embodiment, the main foot support member 1 is made of a circular steel pipe, and other shaped steel pipes can also be used for preparation, such as square-shaped ones; in addition to using plastic materials, the isolation sleeve 3 can also be made of low-cost and easily available materials such as cardboard to protect the main foot support member 1; in this embodiment, the isolation sleeve 3 is a tube with openings at both ends, and the bottom is sealed with an integral fixing plate 5, or a tube with one end sealed can also be directly used as the isolation sleeve 3. The accessories can be square-shaped parts in addition to tube-shaped parts.

[0021] Usage method:

[0022] As Figure 2 , the isolation sleeve 3 is fixed to the bottom of the cast-in-place formwork of the staircase intermediate landing through the fixing nails 6 on the fixing plate 5, and the length of the isolation sleeve 3 is greater than the thickness of the structural slab 9 of the staircase platform after pouring. The main foot support member 1 is inserted into the isolation sleeve 3. According to the length of the vertical rod 8, the positioning pipe 7 is passed through the positioning holes 2 on the main foot support member 1. The vertical rod 8 is sleeved on the upper part of the main foot support member 1, and the bottom of the vertical rod 8 presses on the positioning pipe 7, and the positioning pipe 7 provides support force for the vertical rod 8. The diameter of the part of the vertical rod 8 sleeved on the main foot support member 1 can be a little larger to facilitate sleeving on the main foot support member 1.

[0023] After pouring is completed, the vertical rod 8 is removed from the upper part of the main foot support member 1. Due to the function of the isolation sleeve 3, the main foot support member 1 does not come into contact with the pouring grout, so the main foot support member 1 can be taken out of the isolation sleeve 3 for reuse in the next cycle.

[0024] This device needs to be arranged according to the spacing of the vertical rods in the construction plan, and it is necessary to ensure that this device is installed for each vertical rod on the staircase intermediate platform. When installing the foot support device for the vertical rod, it is necessary to pay attention to aligning the axes of the upper and lower vertical rods and welding the bottom circular steel plate firmly.

[0025] The utility model has a simple structure, is easy to manufacture and process, has a wide range of material sources, can be processed and manufactured on the construction site, and is more practical.

[0026] The above are only the preferred embodiments of the present utility model. It should be understood that the present utility model is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in the relevant field. And the changes and modifications made by those skilled in the art that do not depart from the spirit and scope of the present utility model should all be within the protection scope of the appended claims of the present utility model.
