Preferably, wire rope is used for connecting the pre-buried U shaped steel muscle pull ring in both ends, and the connected mode is wire rope passes behind the U shaped steel muscle pull ring with do not tie up together with the part that passes with the dop, dop quantity is no less than 4, and wherein last dop has 500 mm's interval with preceding one to this section of a safety bend of releasing in the centre, so that detect the dop not hard up and whether wire rope slides.

Preferably, the contact part of the steel wire rope and the floor slab edge is separated by a rubber pad, so that the concrete at the floor slab edge is prevented from being damaged under the continuous abrasion of the steel wire rope.

Preferably, the winch is used for pulling the traction rope to drive the profiled steel sheet to move along the direction of the steel wire rope, and the length of the traction rope meets certain requirements and is slightly longer than that of the steel corridor.

The utility model discloses possess following characteristics:

during the construction of steel structure vestibule, after falling object appears, the high altitude interception is carried out before still not producing great destructive power for the accident that the falling object caused harms and falls to minimumly.

Fig. 2 is an installation schematic diagram of the present invention.

Figure 3 is the utility model discloses with floor connection schematic diagram.

Fig. 4 is a bottom partial schematic view of the present invention.

The labels in the figure are: 1. the steel wire rope comprises a profiled steel plate, 2 steel wire ropes, 3U-shaped steel bar pull rings, 4 traction ropes, 5 steel structure vestibules, 6 chucks, 7 windlasses and 8 galvanized iron wires.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

The utility model discloses before the installation, draw 3 rings pre-buried at the assigned position with U shaped steel, the floor edge of one deck under 5 place layers of steel construction vestibule promptly, every pre-buried point will exceed the projection scope of steel construction vestibule 5 at a distance of 500mm, the pre-buried point at both ends, make the profiled sheet 1 of follow-up laying can cover the projection scope of steel construction vestibule 5 completely.

The pre-buried U-shaped steel bar pull ring 3 does not damage the reinforced concrete structure of the floor slab.

As shown in fig. 3, during installation, the steel wire rope 2 firstly penetrates through the U-shaped steel bar pull ring 3 and is bound with the part which does not penetrate through the steel wire rope pull ring by the clamp heads 6, the number of the clamp heads 6 is more than four, the other end, which is not bound with the steel wire rope 2, of the steel wire rope is pulled down to a floor corresponding to the other main body structure through the winch 7, and the steel wire rope 2 is connected to the U-shaped steel bar pull ring 3 on the side by adopting the same method after being straightened as much. After tying up all wire rope 2 and U type reinforcing bar pull ring 3 together, the position of wire rope and floor limit contact is separated with the rubber pad, and whether the check connection is firm simultaneously, and the accessible increases the quantity of dop 6 and strengthens the fastness.

As shown in fig. 2, after the steel wire rope 2 is installed, a first row of profiled steel sheets 1 is laid on the position of the steel wire rope 2 close to the floor edge, a traction rope 4 is tied, the other end of the traction rope 4 is positioned on the other main structure, a winch 7 pulls the traction rope 4 to drive the profiled steel sheets 1 to move towards the other main structure, a row of profiled steel sheets 1 is added every half meter of movement, the profiled steel sheets 1 and the steel wire rope 2 are bound together by galvanized iron wires 8, the steps are repeated until the first row of profiled steel sheets 1 reaches the floor edge of the other main structure, then the hauling rope 4 is tied on the fixing objects such as the post or the guard rail, the last row of profiled steel plates 1 are also fixed on the fixing objects such as the post or the guard rail by the rope, and the profiled steel plates 1 with two ends close to the main body part have certain inclination when being fixed, but are not completely covered on the steel wire rope 2.

After 5 constructions in steel construction vestibule finish, when needing to demolish protective equipment, will break down the rope that both ends are fixed earlier, reuse hoist engine 7 slowly pulls profiled sheet 1, cuts off the iron wire on profiled sheet 1 when pulling to dismantle 1 one of profiled sheet. After the profiled steel sheet 1 is disassembled, the clamping head 6 at one end of the steel wire rope 2 is firstly removed, then the whole steel wire rope 2 is received on the floor slab, and finally the clamping head 6 at the other end is removed. And (4) finishing all the profiled steel sheets 1 and the steel wire ropes 2, and transporting to a specified place for storage through a construction elevator and a tower crane.

The construction attention problem is as follows: when in site construction, the safety helmet is worn and the helmet belt is buckled; when the safety belt is installed or disassembled, a constructor must fasten the safety belt, and one end of the safety belt is buckled on a fixed component to ensure the life safety of the constructor.
