Description

The utility model relates to the field of heat and power engineering, in particular to water heating systems for buildings, devices for heating floors and walls built into floors or walls and can be used for installing a water heated floor or walls.

From the existing prior art, a heat distribution panel of a heating device is known (utility model patent No. RU156635 dated 05/08/2015) containing a flat base made of a polymer material with low thermal conductivity, one of the sides of which is provided with grooves for installing heating elements of a heating circuit, and a heat distribution coating , placed on the base from the side provided with grooves, characterized in that the base and the heat distribution coating are permanently connected to each other by an adhesive connection to form a multilayer panel structure in the vertical direction, where the base contains a combined combination of grooves with straight and arcuate curved sections, the channels of which are connected between itself with the formation of a continuous contour, and at least one groove is made open on two end sides of the base, and the heat distribution coating is made of a material with high thermal conductivity and contains along the straight sections of the groove profiled longitudinal corrugations, the protrusion of each of which is a mating part of the corresponding base groove, permanently connected with it by an adhesive connection, with the formation of a groove channel for a panel with a heat distribution coating, while the flat surface of the heat distribution coating above the base groove sections with an arcuate curved channel is provided with perforations along the midline the contour of the groove and notches transverse to it with the provision of the possibility of forming perforations and notches along the rupture line of the heat-distribution coating petals and their bending inside the groove channel cavity.

The disadvantage of the described analogue is the inconvenient and not universal arrangement of the grooves for placing the heating elements, implying their laying in a single way.

A plate for laying pipes in a heating system is also known (patent for utility model No. RU169454 dated 02/04/2016), characterized in that it contains a base, on the working side of which a polystyrene film with a tensile strength of 20-70 MPa is applied and rows of bosses are located , made of the above film, while on one side of the plate, the extreme row of bosses is made of a smaller size than the others, the upper part of which is made in the form of a multifaceted element with angles protruding relative to the body of the boss for fixing the tubes to the base, while the rows of bosses form channels with a U-shaped cross-section for laying pipes, and on the base, ribs protruding above the base surface extend from each lug.

The disadvantages of the described analogue are: low material density, unreliable pipe fastening system, plate fragility during installation.

Known heating device (patent No. KR101743005 (B1) from 02.06.2017). The heating device of the present invention is made in the form of a foamed polypropylene plate, and the pad portion is provided with a hose for flowing hot water; the device has a plurality of mounting portions projecting upwardly from the outer surface of the gasket portion, each mounting portion may be formed at intervals at which a hose passage is formed. The device has a plurality of first locating members in the form of cylinders and a plurality of second locating members, the second locating members being cylinders divided into four mounting modules by transverse guide grooves.

The disadvantage of the prototype is the lack of reliability of fixing the hose in the channel, associated with a small area of contact of the hose with the outer surface of the second installation elements.

The closest technical solution chosen as a prototype is the underfloor heating module (patent CN207035279 (U) dated 02.23.2018), which includes a pipe for hot water, housings for keeping heat, one side of the housing for keeping heat is provided with a first recess, the second recess and cassette, the first recess and the second recess are installed perpendicularly, and also includes clamps and cylindrical support protrusions. The diameter of the support lug is 17-19 cm. The body is rectangular, the body is 110-130 cm long and 55-65 cm wide.

The dimensions of the workpiece are standard for manufacturers; the production of water floor panels from extruded polystyrene foam boards of this size is technological and simple. The supporting protrusions set the pipe laying pitch, thus, the supporting protrusions with a diameter of 17-19 cm made in the prototype provide the possibility of laying the heating pipe on the housing of a standard size with a pitch of 170-190 mm, while the thermal efficiency of the heating module with such a laying pitch may be insufficient under conditions cold climate.

When reducing the laying step, it is also important to preserve the manufacturability and ease of installation of warm water floors, since it is obvious that several modules are used to lay the floor, which are interconnected according to the mosaic principle, so one module should be a continuation of another module and the support protrusions described above should coincide and continue each other when connecting modules.

In this regard, the technical task of the claimed utility model is to create a panel for a warm water floor with a smaller pitch of the heating pipe, which has a universal pattern of tracks, which provides the ability to lay and securely fix the pipes of the warm water floor in various ways.

The technical result of the claimed utility model is to increase the thermal efficiency of warm water floor panels having a universal pattern of tracks, which makes it possible to lay and securely fix pipes for a warm water floor in various ways, while maintaining the simplicity and manufacturability of laying panels for a warm water floor.

To achieve this technical result, a panel for a warm water floor is proposed, containing a base made of extruded polystyrene foam, on the working surface of which rows of support protrusions are made, the cross-section of which has the shape of an ellipse, and on the surface areas located between four adjacent support protrusions, groups of four protrusions located in such a way that they form additional channels for laying the tubular elements of the water floor. The protrusions in the mentioned groups are in the form of a straight triangular prism having a right-angled triangle at the base. The protrusions in the group are oriented at right angles to the center of the group and are equidistant from each other and from the cylindrical protrusions adjacent to them. In this case, the base length is 1170-1190 mm, and the width is 570-590 mm, the width of the channel for laying pipes is 13 mm, the smaller diameter of the section of the supporting protrusions is 129.5-134.5 mm, and the larger one is 133-136 mm ... In addition, along the perimeter of the base of the panel, the cross-section of the support protrusions has the shape of a half ellipse, and in the corners - the shape of a quarter of an ellipse.

The indicated base dimensions are standard for manufacturers of extruded polystyrene foam boards, the production of water floor panels from extruded polystyrene foam boards of this size is technological and simple.

Thus, the pipe laying spacing is 129.5-136 mm, which is the most effective for a panel of a given size, since at this laying spacing a single integral pattern of tracks is formed when joining the warm water floor panels, while a smaller laying spacing, at which one-piece pattern when joining, does not allow for high-quality pipe laying, due to the possible formation of its kinks.

The panels have a locking system of joining, which eliminates the possibility of crevice gaps, thereby ensuring the tightness of the underfloor heating structure in relation to the concrete foundations of the building.

The essence of the utility model is illustrated by images of a panel for a warm water floor. FIG. 1 shows an image of a typical panel for a warm water floor, FIG. 2 shows a variant of pipe laying in a panel, where:

1 - slab base;

2 - supporting protrusions;

3 - protrusions in the form of a triangular prism;

4 - pipe;

5 - protrusions in the form of half an ellipse;

6 - projections in the form of a quarter of an ellipse.

The panel for a warm water floor contains a base 1 made of extruded polystyrene foam, on the working surface of which there are rows of supporting protrusions 2, groups of four protrusions are made in the form of a straight triangular prism 3, having a right triangle at the base, arranged in such a way that they form additional channels for laying pipes 4 water floor.

The protrusions 3 in the group are oriented at right angles to the center of the group and are equidistant from each other and from the adjacent supporting protrusions 2.

The panel contains along the perimeter protrusions in the form of half an ellipse 5, as well as a quarter of an ellipse 6 in the corners of the panel.

Installation of underfloor heating using the declared panel is as follows. The required number of panels is laid on the prepared surface, fastening them together using a lock connection. After the panels are laid, heating pipes are laid in the channels of the panels. A heating pipe is inserted into the channels formed between the rows and groups of protrusions, which is tightly fixed in the channel, since its width is essentially equal to or slightly less than the pipe diameter, and fits along a predetermined contour in any direction.

Examples of implementation of the claimed utility model.

Example 1. The length of the base of the panel is 1170 mm and the width is 570 mm, the width of the channel for laying pipes is 13 mm, the smaller diameter of the cross-section of the supporting protrusions is 129.5 mm, and the larger one is 133 mm. When the panels are joined, the half-projections and the quarter-projections form one-piece support projections.

Example 2. The length of the base of the panel is 1190 mm, and the width is 590 mm, the width of the channel for laying pipes is 13 mm, the smaller diameter of the section of the supporting protrusions is 134.5 mm, and the larger one is 136 mm. When the panels are joined, the half-projections and the quarter-projections form one-piece support projections.

Example 3. The length of the base of the panel is 1180 mm, and the width is 580 mm, the width of the channel for laying pipes is 13 mm, the smaller diameter of the section of the supporting protrusions is 132 mm, and the larger one is 134.5 mm. When the panels are joined, the half-projections and the quarter-projections form one-piece support projections.

The declared utility model provides an increase in the performance of the panel for a warm water floor, namely, an increase in the uniformity of heat distribution over the entire surface of the panel due to the possibility of laying heating pipes in a variety of options in different directions, reducing the time spent on installation and laying of heating elements of the heating circuit, provides an increase in strength and reduction of panel fragility. Laying the pipe between the cylindrical protrusion and the protrusion in the form of a straight triangular prism provides a larger area of contact between the pipe and the surface of the protrusions, thereby providing a more reliable fixation of the pipe in the channels of the panel. The pipe laying step is the most effective for a panel of a given size, since at this laying step, a single integral pattern is maintained when joining the warm water floor panels, namely, when the panels are joined, the half-protrusions and quarters of the protrusions form solid supporting protrusions of the same dimensions and the same section in the form of an ellipse, while this step is significantly less than the laying step stated in the prototype, which allows for greater thermal efficiency of the warm water floor. The implementation of the support protrusions in the form of an ellipse allows them to be distributed as accurately and proportionally as possible on the surface of the panel in order to ensure a simple and technologically advanced laying (joining) of the panels.

Analysis of patent and scientific and technical literature did not reveal technical solutions with such a set of essential features, which allows us to conclude that the claimed utility model meets the “novelty” criterion.
