Description

The field of technology.

The utility model relates to the field of construction and can be used in the construction of the internal profile of polyvinyl chloride (hereinafter - PVC) of the door prefabricated box with thermal break.

The level of technology.

From the description of the patent RU 191618 U1, IPC EV 3/70, publ. 08/14/2019, the known design of the door frame with thermal break, which includes connected together an external frame of a metal profile and an internal frame of a PVC profile.

From the description of patent RU 185473 U1, IPC Е06В 5/10, ЕВВ 7/16, publ. 12/05/2018, the design of a prefabricated door frame with a thermal break is known, which includes an external frame of an open metal profile connected together and an internal frame of a closed PVC profile. The description of patent RU 185473 U1 does not indicate how the profiles of the outer and inner frame of the box are connected. The easiest way to do this is with self-tapping fasteners that screw the PVC profile to the wall of the metal profile of the outer frame.

For the closest analogue of the claimed utility model adopted PVC profile (see Fig. 1), known from the description of the patent RU 83275 U1, IPC EV 3/22, publ. 05/27/2009. The analogue is a hollow PVC profile with a step and a cavity for installing an elastic seal, lower, upper and side walls, as well as dividing grooves located on the outside of the profile to indicate the installation location of the fasteners. The closest analogue has the following disadvantages.

The heads of the fasteners protrude on the surface of the upper wall, which is why the door frame with such a profile has an unattractive appearance.

While the dividing groove on the upper wall facilitates the process of screwing the fastener, the protrusion around the dividing groove on the lower wall, opposite the dividing groove on the upper wall, complicates the process of screwing the fastener, contributes to the displacement of the fastener and its deviation from the vertical position.

The surface of the lower wall is provided with protrusions that prevent the profile from adhering to the surface of the outer frame of the door frame.

These shortcomings lead to the unattractive appearance of the door frame, the increased complexity of the door frame assembly and the inability to use this design as part of a door prefabricated box with thermal break.

Disclosure of a utility model.

The objective the utility model aims to achieve is to design a specialized PVC profile for the inner frame of a metal door prefabricated box with a thermal gap, which reduces the complexity of door box assembly in terms of securing the profile with self-tapping fasteners to the outer frame of the box and improves the appearance of the door frame .

The technical results that the utility model aims to achieve are:

- to reduce the complexity of assembling a metal door box with thermal break;

- in expanding the arsenal of technical means of the specified purpose.

The above technical results are achieved in a hollow PVC profile with lower, upper and side walls, as well as the first dividing groove located on the outside of the profile.

The indicated technical results are achieved in that the profile is provided with a channel for mounting fasteners open from the upper wall side, the first dividing groove is made at the bottom of the channel, a second dividing groove is formed on the inner surface of the lower wall opposite the first dividing groove, and opposite on the outer surface of the lower wall channel formed a recess. It is preferable that the width of the auxiliary groove is greater than the width of the marking groove.

A brief description of the drawings.

The utility model is illustrated by the following images. In FIG. 1 shows the closest analogue known from patent RU 83275 U1; In FIG. 2 shows the claimed profile.

With reference to FIG. 1-2 are indicated:

1 - profile; 2 - bottom wall; 3,4- side walls; 5 - upper wall;

6 - channel; 7 - a partition; 8 - bottom of the channel;

9 - means for fixing the decorative lining in the channel;

10 - recess on the bottom wall;

11 - the first separation groove; 12 - the second dividing groove;

13 - inclined partition; 14 - bounding wall;

15 - a cavity for accommodating an elastic seal.

Implementation of a utility model.

The utility model can be successfully implemented in the hollow PVC profile 1 of the door frame, including (see Fig. 2) the lower wall 2, the side walls 3, 4 and the upper wall 5.

The profile is formed from PVC by extrusion.

To implement the utility model, the following changes in the design of the profile are performed.

Profile 1 is provided with a channel 6 for installing self-tapping fasteners, open from the side of the upper wall 5.

The walls of the channel are equipped with means 9 for fixing the decorative lining (the lining in Fig. 1-2 is not shown), which closes the channel 6 after assembly of the box.

At the bottom 8 of channel 6, a first dividing groove 11 is formed to indicate the installation location of the self-tapping fasteners and to facilitate screwing in of the self-tapping fasteners.

A second dividing groove 12 is formed on the inner surface of the lower wall 2 to facilitate screwing in of the self-tapping fasteners.

A recess 10 is formed on the outer surface of the bottom wall 2 opposite the channel 6. The recess is designed to be burr when self-tapping fasteners pass through the bottom wall 2. Without the recess 10, the burrs will prevent the profile 1 from adhering to the surface of the metal profile of the outer frame of the door frame.

Profile 1 may be provided with a cavity 15 for precise installation of the elastic seal. To implement the cavity, for example, form a boundary wall 14 on the step of the profile 1 at a distance equal to the width of the base of the elastic seal.

The assembly of the door frame is carried out by fastening to the wall of the metal profile of the external frame of the profile 1.

Profile 1 is pressed against the surface profile of the outer frame.

Then, a self-tapping fastening element is recessed into the channel and screwed into the first dividing groove 11 at the bottom 8 of channel 6 of profile 1.

After passing the bottom 8 of the channel 6 and the cavity behind it, limited laterally by the inclined partitions 13, the tip of the self-tapping fastener is screwed into the second dividing groove 12 on the inner surface of the lower wall 2 and crosses the lower wall.

In an embodiment of the utility model, the width of the second dividing groove 12 is larger than the width of the first dividing groove 11, since when the self-tapping fastener is screwed, its rod (and tip) can deviate from the vertical.

Due to the presence of the recess 10, the burrs that form on the outer surface of the lower wall 2 are located in the recess and do not interfere with the snug fit of the lower wall 2 to the surface of the metal profile of the outer frame.

Then, the core of the self-tapping fastener cuts a hole in the surface of the metal profile of the outer frame and cuts a threaded coil in the hole, so that profile 1 is fixed to the surface of the metal profile of the outer frame of the box.

Channel 6, after fixing the profile 1 to the outer frame with self-tapping fasteners, is closed with a decorative plate, which is latched into the channel 6 using fixing means 9.

In the cavity 15, an elastic sealant is installed on the adhesive.

The conducted patent studies confirm the world novelty of the utility model.

The operation of the prototypes of the profile confirmed the industrial applicability of the utility model and compliance with the stated technical results.
