Device for strengthening the node supporting the ribbed floor panel

The utility model relates to devices for strengthening nodes of building structures and can be used in the construction, installation and reconstruction of buildings and structures in cases:

1) receiving by the supporting parts of the panels damage during transportation, installation or operation;

2) the need to increase the area of support during reconstruction or to eliminate the consequences of installation errors.

A device for enhancing the overlap of reinforced concrete ribbed panels (see. Copyright certificate for the invention No. 1300133, IPC E 04 G 23/02 Bull. No. 12, 1987).

The device contains reinforcing beams, covering the longitudinal edges of adjacent panels from the bottom and mounted on supports. Each support is made in the form of an upper reinforcing element and screeds missing in the joint between adjacent panels and connecting the upper reinforcing element to the reinforcing beam. At the same time, the length of the gain beam is less than the span of the panel in the light, and the upper gain element is made continuous over the supports of the panels.

In the device, the upper gain element can be made in the form of framing the upper corners of adjacent panels of paired corners. Paired corners are supported by discrete plates with holes for passing screeds.

In the device, the joint between the panels can be filled with concrete. The pediatric device for enhancing the overlap of reinforced concrete ribbed panels is that:

- to strengthen the floor panels, the device is inefficient and material-intensive, since the upper and lower reinforcing elements work without direct connection with the concrete panels, they are connected to concrete only through screeds; - the device does not strengthen the support node.

A device for enhancing the coating of reinforced concrete ribbed slabs (see Patent for invention No. 1813158, IPC E 04 G 23/02 Bull. No. 16, 1993).

The device contains two metal reinforcement beams located on the supporting structure, and transverse traverses rigidly connected to reinforcement beams (from rolling profiles). Each reinforcement beam is made with a horizontally located oval hole for connection to another beam by means of a mounting bolt with the formation of one-sided consoles. The device is equipped with screws and stops, which are rigidly fixed on top of each beam from the side of the console and interact with the side faces of the transverse edges of the plate. On the traverses located on the consoles, screws are installed that interact with the side faces of the supporting structure.

A disadvantage of the device for enhancing the coating of reinforced concrete ribbed slabs is that this device is intended only to increase the reliability of the coating disk by reducing the possibility of horizontal displacement.

The technical task of the utility model is to increase the area of support of the ribbed panel.

The technical result provides an increase in the area of support due to bringing under the ribs of the panel additional supports from the channel, which are part of the support clip mounted on the crossbar.

In FIG. 1 and FIG. 2 shows a diagram of a device for reinforcing a support unit of a ribbed floor panel. The device consists of two channels 1, summed up under the supporting part of the structure, having an insufficient bearing area. The channels 1 are fixed on the crossbar, by including them in a support clip covering the crossbar. The support clip includes, in addition to the said channels 1, connecting elements 2 on top of the crossbar made of a rolled corner, channel or box profile, the measure of which is selected depending on the required bearing capacity

node. The connecting elements 2 are welded to the channels 1, thereby securing them in the desired position in the upper plane of the crossbar. The connecting elements 2 on top of the crossbar are in turn connected in the lower plane of the crossbar using the tie rods and nuts 3 with the connecting elements 4, as well as the connecting elements 2 made of a rolled corner, channel or box profile.

As a result of using this device, the support length of the panel edge is increased by the width of the channel 1. The panel is supported by a crossbar, and also additionally by channel 1. The channel number is selected depending on the required additional support area. The device can be installed before and after mounting the panels.
