RU206767U1 - WATERPROOFING ELEMENT FOR FORMWORK - Google Patents

Abstract

The utility model relates to the field of construction and is aimed at increasing the reliability of waterproofing of buildings and structures and at the same time is used as a shell for a straining screw and a spacer for formwork. The technical result consists in the fact that the waterproofing element for the formwork increases the hydrostatic resistance to water pressure after the concrete has set and increases the reliability of buildings and structures. This task is achieved due to the fact that the waterproofing element for the formwork is made of a round pipe having in the middle a protrusion perpendicularly located relative to the pipe axis, ribbed on the outer and outer sides, which was originally made on this element.

Description

The utility model relates to the field of construction and is aimed at increasing the reliability of waterproofing of buildings and structures and at the same time is used as a shell for a straining screw and a spacer for formwork.

As you know, the clamping screw is designed to increase the ability of the formwork to resist the pressure of the concrete mix by attaching opposing panels. The tie screws are placed inside the pipe to prevent them from adhering to the concrete mix and then unimpeded removal. Since a technological seam is formed at the border of the tube - concrete, additional waterproofing measures must be applied.

Known Wall collar 4 pipes, consisting of round rubber with shelves for attaching to the pipe by means of clamps (https://www.4pipes.de/www_GB_2019_NEU/indexgb_htm_files/Wall%20Collar_GB_2020.pdf).

The disadvantage of the analogue is that it is installed on top of the installed tube, and therefore is accompanied by additional labor costs associated with fastening, as a result of which, with large volumes of construction and installation work, the possibility of errors associated with incorrect fastening increases significantly.

Known constructive solution for sealing holes Sealing UFO (https://www.besealed.com/en/products/hydrophilic-plugs-and-rings/sealing-ufo), consisting of swellable rubber of a circular cross section, put on the tube and held on to it due to pressing forces.

The technical problem of the analogue is that it is made of swelling rubber and swells when it comes into contact with atmospheric precipitation, as a result of which, during and after installation, this device must be protected from contact with moisture before laying the concrete mixture.

The task of the utility model is to develop a constructive solution that minimizes the number of construction and installation works and is not exposed to the environment, also provides free passage of tie screws and their unhindered subsequent extraction when concrete sets, and increases the reliability of waterproofing of buildings and structures by increasing the hydrostatic resistance to pressure water on the border with concrete.

This task is achieved due to the fact that the waterproofing element for the formwork is made of a round pipe having in the middle a protrusion perpendicularly located relative to the pipe axis, ribbed on the outer and outer sides, which was originally made on this element.

The utility model is illustrated by drawings (Fig. 1 and 2)

FIG. 1 shows an image of a waterproofing element for formwork before concreting:

1 - waterproofing element for formwork;

2 - clamping screw;

3 - clamping screw lock;

4 - formwork.

FIG. 2 shows a picture of a waterproofing element for formwork after placing the concrete:

1 - waterproofing element for formwork;

5 - cavities filled with cement-sand mortar;

6 - hydrostatic water pressure;

7 - soil;

8 - concrete.

This problem is solved due to the fact that, before the start of concreting, the waterproofing element for the formwork is attached to the opposite formwork panels by free passage of the tie screws inside it and their subsequent attachment to the outer side of the formwork using locks.

The technical result consists in the fact that the waterproofing element for the formwork increases the hydrostatic resistance to water pressure after the concrete has set and increases the reliability of buildings and structures.
