[0023] In order to make the purpose, technical solution, design method and advantages of the utility model clearer, the utility model is further described in detail through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] like Figure 1 and Figure 2 As shown, the utility model provides a support device for casting horizontal openings in a floor slab, the purpose of which is to solve the problem of difficulty in supporting the template at the bottom of the horizontal opening, comprising a casting template 3, which is arranged at the bottom of an upper floor slab 1 and is used to block the reserved opening 2 on the upper floor slab 1; the support device also includes an upper support plate 4, a support steel pipe 7 and a lower support plate 10; wherein the upper support plate 4 is located at the bottom of the casting template 3, and is fixedly connected to the casting template 3 by rivets or bolts, the top of the support steel pipe 7 is connected to the upper support plate 4, the bottom of the support steel pipe 7 is connected to the lower support plate 10, the lower support plate 10 is located on the lower floor slab 11, and the position of the lower support plate 10 is adapted to the above-mentioned upper support plate 4, so that the support steel pipe 7 is coaxial with the reserved opening 2; since in the initial stage of construction, the positions of the reserved openings 2 on the coal seam floor slab are all coaxially arranged, therefore, in order to ensure that the support steel pipe 7 is in a vertical state, it is necessary to arrange the lower support plate 10 at the reserved opening 2 of the lower floor slab 11.

[0025] For most buildings, the floor height is fixed, but there are also non-standard floor heights. Therefore, in order to improve the applicability of the present device, a first adjustment component is provided between the upper support plate 4 and the support steel pipe 7 to adjust the distance between the upper support plate 4 and the support steel pipe 7, and a second adjustment component is provided between the lower support plate 10 and the support steel pipe 7 to adjust the distance between the lower support plate 10 and the support steel pipe 7.

[0026] Specifically, the first adjustment component includes a top support screw rod 5 and an upper turn buckle 6, one end of the top support screw rod 5 is connected to the upper support plate 4, the other end of the top support screw rod 5 extends to the inside of the support steel pipe 7, the upper turn buckle 6 is threadedly connected to the top support screw rod 5 and the upper turn buckle 6 abuts against the support steel pipe 7. The second adjustment component includes a bottom support screw rod 8 and a lower turn buckle 9, one end of the bottom support screw rod 8 is connected to the lower support plate 10, the other end of the bottom support screw rod 8 extends to the inside of the support steel pipe 7, the lower turn buckle 9 is threadedly connected to the bottom support screw rod 8 and the lower turn buckle 9 abuts against the support steel pipe 7, and a rib plate 12 is provided on the circumferential side of one end of the top support screw rod 5 close to the upper support plate 4 and the circumferential side of one end of the bottom support screw rod 8 close to the lower support plate 10, and the rib plate 12 is connected to the upper support plate 4 and / or the lower support plate 10.

[0027] like Figure 3 As shown, the upper turn buckle 6 and the lower turn buckle 9 have the same structure, both including an integrally formed first sleeve 15 and a second sleeve 16, and the inner diameter of the first sleeve 15 is larger than the inner diameter of the second sleeve 16, and a boss 13 is formed between the first sleeve 15 and the second sleeve 16; a thread is machined inside the second sleeve 16 and is threadedly connected to the top support screw rod 5 and / or the bottom support screw rod 8; a rotating handle is provided on the outside of the first sleeve 15.

[0028] In this embodiment, the inner diameter of the first sleeve 15 is larger than the outer diameter of the supporting steel pipe 7, and the inner diameter of the second sleeve 16 is smaller than the outer diameter of the supporting steel pipe 7, so that the end of the supporting steel pipe 7 abuts against the boss 13. In the process of tightening the upper turn buckle 6 or the lower turn buckle 9, since the inner diameter of the first sleeve 15 is larger than the outer diameter of the supporting steel pipe 7, the first sleeve 15 will be wrapped around the end of the supporting steel pipe 7, and since the inner diameter of the second sleeve 16 is smaller than the outer diameter of the supporting steel pipe 7, the end of the supporting steel pipe 7 will abut against the boss 13.

[0029] When sealing the horizontal opening, the support device is assembled according to the above scheme, the bottom of the reserved opening 2 of the upper floor slab 1 is sealed by the casting template 3, and concrete is poured on the casting template 3 to achieve the sealing of the horizontal opening, which can effectively avoid the risk of leakage during the pouring process. After the concrete strength reaches the standard, the support device is removed and the surface of the casting template 3 is cleaned for the next turnover.
