The invention relates to the construction industry, in particular to the testing of materials of building structures and coatings.

A device for testing a NIL of masonry is known, which includes a frame with stands, a load device, a gripper with a support, and a measuring device lJ.

A single-code device cannot be used to determine the strength of the coating material.

The closest technical solution to the invention is a device for assessing the quality of the surface of building materials, including a frame with racks, a load, a device, a working body, a gripping device associated with a load device, and a measuring device f2j.

A disadvantage of the known device is that it cannot be used to determine the strength of the coating material.

The purpose of the invention is to increase work efficiency.

I

The goal is achieved by the fact that, in a device for assessing the quality of the surface of building materials, including a frame with racks, a loading device, a working body, a gripping device with a support connected to a narruzochny device, and a measuring device, the racks are provided with a plate, the working body is made in the form two coaxially mounted rings with protrusions on the ends, while the plate is made with stops for engagement with the protrusions of the lower end of the lower ring, and the grip with stops for engagement with the protrusions of the upper ends of the rings.

FIG. 1 shows a device for determining the adhesion, neither the coating material g with the surface of the building product, a general view; in fig. 2 is the same when determining the strength of the coating material.

The device for assessing the quality of the surface of building materials consists of a frame 1 with racks 2, a load device 1 m in the form of a press 3 and a pressure gauge 4. The working part of the device is made in the form of coaxially mounted rings 5 with protrusions 6 on the ends. Press 3 is connected to rings 5 by

rocker arms 7, tg 8 and grip 9, having protrusions for interacting with the upper protrusions 6 of the rings 5.

The device is provided with a movable support 10 made of two plates that are in contact with each other by means of rollers, for example of a spherical shape. The movable support is installed between the press 3 and the beam 7.

The stitches 2 are provided with a stove 11c with stops. For interacting with the projections 6 of the lower ring 5. The stands, 4 and the lower ring 5 are placed on the surface 12 of the test article.

The device works as follows.

On the surface 12, the quality of which must be determined, two rings 5 are coaxially installed, the contacting ends of which are coated with an anti-adhesive lubricant, for example, petroleum jelly. The cavity of the rings 5 is filled with the coating material. After recruitment; the required strength of the coating material determines the amount of adhesion of the coating material to the surface of the product under test. For this, the gripper 9 is fixed on the upper protrusions 6 of the lower ring 5. The press 3 creates a force ensuring the detachment of the lower ring 5 from the surface 1.2, the value of which is determined by the manometer 4. By the magnitude of the opening force, the quality of surface preparation of the building material for application cover on it.

The strength of the coating material is then determined. Dp of this grip 9 is mounted on the upper ring 5 (Fig. 2), and plate 11 is mounted on the Nines ring 5. The force that ensures the separation of the rings 5 from each other is judged on the strength of the coating material

The device can be used to determine the strength of the surface layer of building materials. To do this, one of the rings 5 is installed on the test surface 12, filled with high-strength material, for example, epoxy resin with a hardener, and it is cut open. The tearing force is judged on the surface strength of the tested product. 3 The use of the invention allows, using a single device, to determine the adhesion of the coating material to the surface of the test article, the strength of the coating material and the strength of the surface layer of the building product.
