A combined ladder formwork

Abstract

The invention discloses a combined type stair formwork. The combined type stair formwork is a mold assembly defined by six main form boards and provided with two steps. Each main form board is formed by vertically welding reinforcing battens to the periphery of a flat plate. Bolt holes for mounting of the side face main form boards are machined in the front battens and the rear battens of the upper step and the lower step, and a tubular sleeve for drawing is welded to the crossed position of the middle batten of the main form board of the upper step. A bolt through hole for fixing the upper main form board is machined in the left side of the middle batten of the lower step. A porous square plate is fixed to the side face of the through hole through a bolt. The left end of the square plate and the battens of the upper main form board are welded. An inclined guide pipe is welded to the right end of the middle batten of the lower step. The combined type stair formwork has the advantages of being simple in structure, easy to mount, convenient to operate, small in size, small in number of accessories, low in machining cost, low in labor intensity, wide in application range, safe, reliable and the like.

Description

technical field [0001] The invention belongs to the field of civil buildings and relates to a combined ladder formwork. Background technique [0002] In the current domestic construction industry, the building construction process often involves the grouting construction process of the stairs between the upper and lower floors. Conventional construction methods are extremely cumbersome and have many disadvantages: 1. The consumption of formwork materials is large and the waste is serious; 2. Wastes cause environmental pollution, and cleaning is troublesome; 3. The process of installing and removing formwork is labor-intensive; 4. The internal quality of the ladder 5. The mold support is not safe; 6. Surface treatment is required after taking the mold; 7. It is not easy to install guardrails; 8. There are potential safety hazards in the pouring process; 9. The loss of cement slurry is large; 10. The construction period is long It is easy to cause delays in work. Contents o...
