SU924329A1 - Device for fencing-off openings in building structures - Google Patents

Description

The invention relates to enclosing devices and can be used on a construction site to protect installers from a constructed building for residential, industrial and cultural purposes from falling.

It is known fencing device containing brackets mounted on the elements of the building with fixed fencing elements (.11.

The closest technical solution to the present invention is a device for fencing the openings of buildings under construction, including collars mounted on columns with hinged rods with fencing nets with a carrying cable fixed on them [21.

The tensioning device in the known devices is made in the form of a drum with a ratchet mechanism, which has a relatively small reliably2

| STI and considerable complexity; in operation and manufacture.

The purpose of the invention is to increase safety due to the effectiveness of the tension of the rope.

This goal is achieved due to the fact that the device including collars mounted on the columns with hinged rods and guard nets with carrying cable fixed to them is provided with carriers, each of which has paired rollers, one of which is fixed rigidly, and the second is mounted with the ability to move, while one of the yoke of the clamp is made in the form of a rocker arm attached to the column.

FIG. 1 shows the proposed device, a general view; in fig. 2 section aa in FIG. in fig. 3 - kinematic scheme of the tension of the rope is retired.

The device consists of clamps with

articulated rods 1 attached to

3,924,329

four

the columns of the building, and fencing nets

2 strung between these clamps.

Collar 1 is a closed hinge design that allows you to cover the column and gain a foothold 5 to it. Clamp 1 has two drove

3, which can be rotated 180 °. Each carrier is equipped with two rollers: a fixed 4 and a movable 5, which moves along the carrier dro. To the lead screw 6.

The collar is provided with a rocker arm 7, swinging on the support 8, ensuring the alignment of forces in the rods 9 when securing the collar to the column.

A device for fencing openings of building structures is installed around the perimeter of the installed floor of a frame-panel building in the area of building and assembly work, as well as between floors in places where there are no wall panels.

The synthetic mesh is attached to the collars and its tension is made in the following sequence: for the 25 fasten the collars to the columns, lay them from the center of the collars to the sides, the rope 10 of the mesh 2, passing by the fixed roller, bends around the movable roller and fastens to the eye with rack 11 carrier drove turns 180 ° and is locked in this position. At the same time the preliminary tension of a grid is made. „

For the implementation of the additional tension of the grid, the movable roller 5 moves along the carrier. The additional tension of the net is equal to the double stroke of the rolling roller 5.

The introduction of the proposed device for the protection of the openings of building structures on construction sites will increase the safety of work at the facilities and improve operation.

Claims (1)

Claim Device for fencing openings of building structures, including collars mounted on columns with hinged rods and fencing nets with a carrying cable fixed on them, characterized in that, in order to increase safety by the effectiveness of rope tension, it is equipped with carriers, each of which has paired rollers, moreover, one of them is fixed rigidly, and the other is mounted so that it can be moved, while one of the yokes of the clamp is made in the form of a yoke attached to the column.
