Embodiment Construction

[0014] Such as figure 1 and figure 2 As shown, it is a schematic diagram of a vertical combined stair board mold, including step formwork (1), step back formwork (2), connection side formwork (3), reinforcement side formwork (4), formwork reinforcement strips (5), upper Platform extension frame (6), step anti-slip protrusions (7), upper platform embedded parts (8), lower platform embedded parts (9) and railing reserved hole embedded parts (10); the step formwork (1) is a ladder shape, the step back formwork (2) is in the shape of a slope, prefabricating a stair slab requires a modular staircase formwork, including a step formwork (1), a step back formwork (2), and two supporting side formwork reinforcements (4) , One upper platform extension frame (6), two upper platform embedded parts (8), two lower platform embedded parts (9), several steps anti-skid protrusions (7), four railing reserved hole embedded parts ( 10); the reinforced side formwork (4) is set at both ends of t...

Abstract

The invention relates to a vertical composite stair mold. The vertical composite stair mold comprises step templates, step back templates, connecting side templates, reinforcing side templates, template reinforcing bars, upper platform lengthening frames, step antiskid bulges, upper platform embedded parts, lower platform embedded parts and handrail preformed hole embedded parts, wherein the reinforcing side templates are arranged on both ends of the space formed by the step template and the step back template of the same module, the upper platform lengthening frames are arranged on upper platforms of the step templates, the upper platform embedded parts are symmetrically fixed to the upper platforms of the step templates, the lower platform embedded parts are symmetrically fixed to lowerplatforms of the step templates, two groups of parallel step antiskid bulges are arranged on each step, and the handrail preformed hole embedded parts are arranged on the same side of the step templates; both ends of the multi-module stair mold are connected by the connecting side templates, the final step template is matched with one step back template so as to be used as a side mold, and two groups of template reinforcing bars are installed on the step back templates on both sides. A plurality of stairs can be produced at the same time, the occupied area is small, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the field of templates, and relates to a mold for vertical combined stair boards, which is widely used in the production of prefabricated stair components. Background technique [0002] In traditional building construction, stair slabs are prepared by on-site support formwork, pre-embedded steel bars, pouring concrete, and natural maintenance, which has disadvantages such as long construction time, large labor demand, and poor on-site construction environment. Therefore, the traditional cast-in-place stair slabs have been developed to prefabricated stair slabs, that is, the stair slabs are produced in the workshop and transported to the site for installation. The production of stair slabs in the workshop requires a separate mold assembly for each stair slab, which occupies a large area, and the production efficiency cannot meet the large-scale production in the existing market. Therefore, the present invention provides a verti...
