Abstract
The utility model discloses a safety protection platform for a pre-embedded pull ring type elevator shaft. The safety protection platform is characterized by comprising elevator shaft beams, pull rings, a keel, and a surface layer. Each pull ring is a U-shaped piece, two arms at a first end of each pull ring are bent away from each other, and a second end of each pull ring is an arc end. The first end of each pull ring is embedded into an upper portion of each corresponding elevator shaft beam, and the second end of each pull ring is exposed and is bent toward the inside of an elevator shaft opening. The keel is fixed to the second end of each pull ring. The surface layer is fixed to the keel. Compared with a scaffold disposed inside an elevator shaft, the safety protection platform enables procedures and costs of materials to be reduced, and is more economical. The platform is built each time when a side mold is dismounted, so that an edge opening can be sealed in time, and thus the platform is safer. No vertical rods are adopted, and the verticality of the vertical rods and pre-embedded wall connection members need not to be controlled. The platform can be directly conveyed through a construction elevator, and thus is high in operability.
Description
Technical field
The utility model relates to elevator shaft safety protection facility, espespecially a kind of pre-buried draw-ring type elevator shaft security protection platform.
Background technology
Making of fastener type steel pipe scaffold while protecting in elevator shaft, due to limited space in elevator shaft, set up and easily have influence on carpenter after scaffold and install template, if and it is easily crooked, dangerous to control bad scaffold while setting up, the material consumptions such as scaffold are larger, it is more manually to set up and remove man-hour, affects the duration, and cost is larger.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, and a kind of pre-buried draw-ring type elevator shaft security protection platform is provided.The technical scheme that realizes above-mentioned purpose is:
The pre-buried draw-ring type elevator shaft of one of the present utility model security protection platform, is characterized in that, described security protection platform comprises:
A plurality of side bars of described elevator shaft;
Draw ring, the first end of described draw ring is embedded in described elevator shaft side bar top, and described draw ring exposes with respect to the second end of first end;
Keel, described keel are fixed on the second end of described draw ring;
Surface layer, described surface layer is fixed on described keel.
Described draw ring is U-shaped, and its first end two arms are to mutually away from direction bending, and the second end is circular arc.
The first end of described draw ring is fixed in the steel mesh reinforcement of described elevator shaft side bar; Described draw ring the second end is to elevator shaft mouth inner bending.
Described keel comprise main joist and secondary joist, and described main joist is sheathed on the second end of described draw ring, and described main joist top is provided with locating part; Described secondary joist sets up and is fixed on described main joist.
Described surface layer comprises flitch and panel, described flitch fixing with described secondary joist on, described panel is layed on described flitch.
The utility model has been owing to having adopted above technical scheme, makes it have following beneficial effect to be:
1, economy: compare the way of setting up scaffold in elevator shaft, draw-ring type elevator shaft protective platform can reduce operation and material cost, every one deck it than few four vertical rods of scaffold, take less cross bar No. one time, do not need pre-buried wall-connecting piece;
2, safety: while being used as the use of decoration scaffold through calculating this platform, safety factor is 11.4>8, safe and reliable.And just that this putting up platform is good in the time that each carpenter removes side form, can accomplish the timely sealing to facing hole, limit;
3, operability: putting up platform is very simple, is no more than floor height if require in accordance with regulations each its of operation to set up scope of operation height.Compare and set up scaffold, this platform, without vertical rod, does not need to control vertical rod verticality and pre-buried wall-connecting piece, when dismounting, can directly by construction elevator, material be transported to floor.
Therefore a kind of pre-buried draw-ring type elevator shaft security protection platform of the utility model has the stronger market competitiveness and good popularizing application prospect.
