Detailed Description
In order to make the objects, technical solutions, and achievement of the objects and effects of the present utility model comprehensible, preferred embodiments accompanied with figures are described in detail below for understanding by a skilled person.
It should be noted that, in the description of the present utility model, unless explicitly specified or limited, terms such as "mounted," "connected," and the like are to be construed broadly and may be either fixed or removable; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium.
As shown in fig. 1 to 3, the stair formwork support comprises an upper formwork 1 and a lower formwork 2 capable of accommodating the upper formwork 1, wherein the upper formwork 1 is formed by welding steel plates and steel profiles, and the lower formwork 2 is formed by connecting wood plate nails. Further simplifying the manufacturing process and reducing the manufacturing cost.
As shown in fig. 3, the lower die carrier 2 is formed by connecting a bottom plate 102 and a side plate 103 by nails, the side plate 103 is provided with a slide groove 101 with a plumb upward, and the slide groove 101 is formed by connecting two thin plate nails to the side plate 103. A sliding plate 201 fixedly mounted on the upper die carrier 1 is connected in a sliding manner in the sliding groove 101, the sliding plate 201 is fixedly mounted on the upper side wall of the support body 202, and the sliding plate 201 extends along the plumb direction corresponding to the sliding groove 101. So that the slide 201 slides up along the plumb of the chute 101 when the upper die carrier 1 is lifted up in a lifting manner. Therefore, deformation of the step edges and corners caused by collision between left and right deflection of the upper die carrier 1 and the stair steps after pouring in the process of lifting and disassembling the upper die carrier 1 is avoided.
As shown in fig. 2, the upper mold frame 1 further comprises a support body 202 extending along the inclined direction of the stairs, a plurality of step templates 204 are fixedly mounted on the lower side wall of the support body 202, and the number of the step templates 204 is welded according to the number of steps of the stairs, so that when concrete is poured into the groove 104 of the lower mold frame 2, the step shape of the stairs is molded through the step templates 204. The step form 204 can be accommodated in the groove 104 formed by the bottom plate 102 and the side plates 103 of the lower die frame 2, and two ends of the step form 204 can be tightly contacted with the inner side walls of the side plates 103, so that concrete on the step is prevented from leaking from two sides of the step form 204 when concrete is poured.
As shown in fig. 2, the two ends of the bracket body 202 are both provided with an adjusting assembly 203, the adjusting assembly 203 comprises a screw 2031 slidably connected with the bracket body 202 along the plumb direction, a nut 2032 for supporting the bracket body 202 is screwed on the screw 2031, and the interval between the lower end of the step template 204 and the bottom plate 102 is adjusted by the rotatable nut 2032.
