Description
Technical Field
[0001] The utility model relates to the technical field of residential staircase formworks, in particular to a combined formwork for one-time molding of residential staircases. Background Art
[0002] The building formwork is used to support the pouring of concrete. After the concrete is poured and formed, the formwork will be removed.
[0003] The stair formwork support system, like the skeleton of stair construction, undertakes the important mission of bearing the pressure of concrete pouring and ensuring the stability of the formwork.
[0004] In the prior art, the stairs cast by the stair formwork lack drip line grooves, which are all modified in the later stage of construction. The prepared drip line (groove) materials are pasted on the wall in order. When pasting, it should be ensured that the drip line (groove) is tightly fitted to the wall surface without gaps.
[0005] Because the drip line needs to be constructed later, which increases the production cost and construction time, we propose a combined formwork for one-time forming of residential stairs. Utility Model Content
[0006] 1. Technical issues to be resolved
[0007] In view of the deficiencies in the prior art, the utility model provides a combined template for one-time forming of residential stairs, which eliminates the need for later installation or construction of drip lines for finished products. The overall appearance is beautiful, cost-effective, and time-saving, and can effectively solve the problems in the background technology.
[0008] (II) Technical solution
[0009] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a combined formwork for one-time forming of residential stairs, comprising an upper formwork, side panels and a lower formwork, the number of the side panels is two groups, a second tensioning screw is connected between the two groups of side panels, a first tensioning screw is connected between the upper formwork and the lower formwork, and a reinforcing steel pipe is provided on the upper end outer surface of the first tensioning screw, and drip line grooves are opened on the left and right sides of the upper end outer surface of the lower formwork.
[0010] Preferably, the two groups of side panels are located on the left and right sides between the upper template and the lower template.
[0011] Preferably, a first mounting hole is formed on an outer surface of one side of the side plate.
[0012] Preferably, a second mounting hole is provided in the middle of the outer surface of the upper end of the lower template.
[0013] Preferably, an exhaust hole is provided on the front outer surface of the upper template.
[0014] Preferably, three groups of exhaust holes are drilled in the upper template in each step.
[0015] (III) Beneficial effects
[0016] Compared with the prior art, the utility model provides a combined formwork for one-time forming of residential stairs, which has the following beneficial effects:
[0017] 1. The combined formwork used for one-time forming of residential stairs is provided with drip line grooves on both sides of the lower formwork. The main structure of the stair drip line is formed in one time. Compared with the traditional finished drip line installed later, it is firm, not easy to fall off, beautiful, saves construction time, saves costs, is applicable, durable, and avoids common quality problems.
[0018] 2. The combined formwork for one-time forming of residential stairs has exhaust holes on the outer wall of the upper formwork, which is convenient for emptying during concrete pouring and improves the quality of stair pouring. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0025] This embodiment is a combined formwork for one-time molding of residential stairs.
[0026] like Figure 1-4As shown, it includes an upper template 1, side panels 2 and a lower template 8. The number of side panels 2 is two groups. A second tension screw 4 is connected between the two groups of side panels 2. A first tension screw 3 is connected between the upper template 1 and the lower template 8. A reinforcing steel pipe 5 is arranged on the upper end outer surface of the first tension screw 3. Drip line grooves 9 are opened on the left and right sides of the upper end outer surface of the lower template 8.
