SU979601A1 - Sliding form for erecting ferroconcrete structures with reinforcement framework - Google Patents

Description

The invention relates to the construction and can be used for the construction of reinforced concrete structures with reinforced frames. Known sliding formwork for the construction of reinforced concrete walls, including a working platform with jacks, shields and latches

The disadvantage of this formwork is the need for laborious work to fix the armakarkas in the working position and to keep them in the design position while continuously moving the formwork.

Closest to the present invention is a sliding formwork for the erection of reinforced concrete structures with an armature frame, including formwork panels, a transfer mechanism and a working platform with movable grippers C2.

The disadvantage of this formwork is that it does not allow the reinforcement work when the formwork is moved horizontally.

The chain of the invention is a reduction in labor costs when installing reinforcement cages.

The goal is achieved by the fact that sliding formwork for

erection of reinforced concrete structures with an armakkas, including formwork shields, a moving mechanism and a working platform with movable grippers, equipped with a horizontal rigid beam installed on the working platform and associated with the latter by means of gears made

10 crank-yoke, the connecting rod of each of which is pivotally connected with a rigid beam.

FIG. Figure 1 shows the slide. formwork at the time of installation of the framework 15; in fig. 2 - the same in the process.

The sliding formwork consists of carriages with displacement drives 1, which, through a friction pair 2 and

20, the chain drive 3 is connected to a driving lever 4 mounted on bearings 5, mounted on a working platform 6 and on a stand 7.

The drive lever 4 is pivotally connected to the connecting rod 8, which is also pivotally connected to the swinging lever 9. On the connecting rods 8 a rigid beam 10 is fixed, on which retractable clamps 11 are mounted, fixing the position of the reinforcement cages 12.

thirty

The frames are supplied to the design position using an electric hoist 13 mounted on a monorail 14.

The formwork works as follows.,.

The installed reinforced cage 12 is supplied by an electric hoist 13 to the retractable clamps 11, after which the electric hoist 13 is released, and the reinforced carriages 12 are held in the design position with the help of the retractable grips 11. The reinforcing cages 12 are made without stopping the formwork, the sliding hooks 11 are mounted on the ball 11 and the arms are fixed without the formwork, 11 moving along the straight-line portion of the trajectory I-II, allowing the reinforcement cage 12 to remain stationary for the time required to weld with the previous frame.

The movement of the rigid beam 10 is transmitted through a swinging arm 9 connected by a crosspiece 8 and a driving lever 4, which through a chain drive 3 and a friction pair 2 receives movement as the sliding formwork with the drives is moved 1.

Then, the whole system moves to the next reinforcement cage length, and the cycle repeats.

The application of the proposed formwork allows industrializing the installation of armature frames and makes it possible to reduce the labor intensity and duration of reinforcement by 1.5-2 times, significantly reduce the costs of timber and metal for constructing temporary scaffolding and scaffolding, allows both reinforcing and concrete works .
