Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in the mounting structure of a floor panel.

[Prior art]

Ceramic floor heating panels have a structure in which electric heating wires (heat-generating resistance wires), sheet heaters, etc. are built into a ceramic base formed underneath the panel, or are attached to the outside surface. By attaching this to the floor, it is possible to heat the room from the floor.

By the way, when installing the above-mentioned floor heating panel on an indoor floor, the floor surface is often not level due to unevenness, so it is necessary to install it on the floor surface and support the panel from the bottom side. It was necessary to adjust the level by changing the height of the support metal fittings used, but in the conventional construction method, the number of steps required for the support metal fittings used was
There was a problem with lm not being able to change fte.

In addition, the above-mentioned support fittings have their receiving parts supporting only each corner of the floor heating panel, so if a person or object is placed on the panel and a load is applied, the panel will loosen significantly, especially in the center. As a result, the heat-generating resistance wire is pulled, causing it to break mechanically, and eventually the panel itself to ruptures.

In addition, in the past, during construction (installation), the position of the panels placed on the support plate was not determined, so the distance (spacing) between adjacent panels was not constant, which caused the problem that orderly joints could not be formed. there were.

Furthermore, in the past, when a fluid joint material was filled into the joint from the upper surface side of the panel, there was a problem in that the joint material leaked downward.

[Means to solve the problem]

The present invention is intended to solve the above-mentioned problems, and includes a horizontal portion 4a formed of a long plate material, and a central portion that bisects the horizontal portion 4a in the short direction. A receiving bracket 4 includes a projecting wall 4b formed in a direction, a vertical portion 4c vertically disposed on the lower surface of the horizontal portion 4a, an installation leg 5a separately installed on the floor, and an installation leg 5a that stands up on the upper surface of the installation leg 5a. an installation fitting 5 consisting of a vertical portion 5b, and both vertical portions 4e, 5;
This is characterized by an adjustment fitting that connects the horizontal portions 4a and 58 of the mounting legs 58 to each other and adjusts the distance between the horizontal portions 4a and the installation legs 58.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

1 is a floor surface, 2 is a support fitting installed on the floor surface,
The support metal fitting 2 includes a long receiving metal fitting 4 that supports the floor heating panel 3, and an installation metal fitting 5 installed on the floor surface l.
It is comprised of an adjustment fitting 6 which connects the receiving fitting 4 and the installation fitting 5 and further adjusts the height h of the supporting fitting.

Further, the above-mentioned receiving fitting 4 is located at the center of the long horizontal part 4a supporting the entire length of the lower surface side edges 3at to 3b in the longitudinal direction of the above-mentioned panel 3, and is located at the center of the horizontal part 4a. It consists of an upper protruding wall 4b that bisects the part in the short direction, and a rod-shaped vertical part 4c that projects vertically downward from the horizontal part 4a, and a male threaded screw at the lower end of the vertical part. A portion 4d is formed. In addition, regarding the above-mentioned upper protruding wall 4b, there is a constant interval a (
However, as shown in Fig. 2, special measures were taken to form a constant interval aI (joint) between adjacent panels 3, 3'' in the front and back direction. Further, in the horizontal part from the center, an auxiliary projecting wall 4b' is provided which is arranged perpendicularly to the projecting wall 4h formed in the longitudinal direction. Alternatively, as shown in FIG. 3B, a recess 4b' may be formed in the lower part of the auxiliary projecting wall 4b', and this may be formed at right angles from three sides to the projecting wall 4b. (cross) so that the auxiliary projecting wall 4b can be slid in the front-rear direction relative to the projecting wall 4h, the mounting position can be changed depending on the length of the panel to be placed. However, in this case as well, the height of the projecting wall 4b needs to be such that it does not extend beyond the top surface 3c of the panel 3.

Further, the above-mentioned installation fitting 5 consists of horizontally formed installation legs 5a to be installed on the floor surface 1 and a bar-shaped vertical part 5b formed to protrude upward from the spread legs 5a. Furthermore, a male threaded portion 5c is formed. A plurality of these installation fittings 5 are provided at appropriate intervals over the entire length of the elongated receiving fitting 4, but it is preferable to provide them at least at three locations at both ends and at the center of the receiving fitting. Note that, as a matter of course, a plurality of vertical parts 4c are fixed to the horizontal part 4a of the receiving metal fitting in correspondence with the above-mentioned installation legs 5a. Also,
Reference numeral 6 denotes a pipe-shaped adjustment fitting, and as shown in Fig. 4, threaded portions 6a and 6b consisting of ring threads are formed on the inner circumferential surfaces of the upper and lower parts, respectively, and furthermore, the outer circumferential surface of the fitting has a diameter of six. Rotary operation parts 6c each having a square shape or a low left for non-slip are formed, and the upper threaded part 6a is connected to the threaded part 4d of the vertical part 4c of the receiver 4, and the lower threaded part 6
b are screwed to threaded portions 5c of the vertical portion 5b of the installation fitting 5, respectively. In other words, the upper and lower screw portions 6a and 6b of the adjustment fitting 6 have a reverse thread relationship, and by turning the adjustment fitting, the length of the connecting portion, that is, the height h of the support fitting 2 can be adjusted. It is now possible to change. Therefore, even if the floor surface 1 has some irregularities, the horizontal portion of the support metal fitting can be leveled by rotating the metal fitting. Installation legs 5 formed horizontally
An adhesive 7 made of a rubber adhesive or double-sided adhesive tape is attached to the back surface 5a+ of a, so that the support fitting 2 can be stably installed on the floor 1. There is. Note that thick adhesive is used for this adhesive.

Next, the floor heating panel 3 will be explained.

The panel 3 is formed into a rectangular shape so as to be placed on both the left and right sides of the land clearing with the upper protruding wall 4b formed at the center of the horizontal part 4a of the support metal fitting as a boundary, and as shown in FIG. It has a cross-sectional structure. That is, a heat insulating material 10 such as glass wool is bonded to the back surface 9a of the ceramic base 9. The above-mentioned lining insulation material 10 is originally provided for the purpose of preventing the heat from the heating resistance wire 8 from escaping downward as much as possible, but it also increases the mechanical strength of the ceramic base 9. This is also the objective. As the above-mentioned heat insulating material 10, glass wool, asbestos wool, foamed concrete, foamed urethane rubber, cork, various wooden boards, various inorganic boards, etc. are used alone or in combination depending on the purpose and use. Furthermore, the heat generating resistance wire 8 described above may be formed by using a heat generating resistance wire such as a nichrome wire, by forming a resistance pattern by means such as printing or thermal spraying, or by using a planar heating element. It is conceivable that the resistance wire may be adhered to the back side of the base 9 with an adhesive and then affixed with insulating caulking, or particularly in the case of a fully bent resistance wire, it may be inserted into the base. .

Although not particularly shown, the heating resistance wires between the adjacent floor heating panels 3, 3', 3'', etc. are electrically connected when the support fittings are placed on the horizontal part. Of course, it is understandable that the current-carrying circuit is formed by

Next, a case will be described in which a ceramic floor heating panel is constructed using the support fittings 2 described above.

A mounting position is drawn by a marked line on the floor 1 on which the floor heating panel 3 is scheduled to be installed, and the support fittings 2 are temporarily installed along the line.

In the above, if the horizontal level of the floor surface (the level of the holder of the support metal fitting) is not reached, the height h of the horizontal part 4a of the support metal fitting is adjusted using the adjustment metal fitting 6 to level it out.

Once the level is reached, peel off the release paper of the double-sided adhesive tape 7 on the back 5a+ side of the installation leg 5a of the installation fitting 5, and firmly press the tape against the floor 1 to adhere the installation fitting 5 onto the floor. and stabilize it.

In this state, the floor heating panels 3, 3' are placed on both sides of the horizontal part 4a of the receiving metal fitting 4, with the projecting wall 4b in the center.

Further, other panels 3'' and 3'' are placed on the horizontal portion adjacent to the front or rear of the same panel 3.

The panels 3 placed adjacent to each other in the front and back are positioned not only along the projecting wall 4b but also along the auxiliary projecting wall 4b'.

The joints a, a' formed by the last placed panels 3.3', 3''... are filled with a heat-resistant joint material 11 such as silicone or white cement 1- from above. The installation (assembly) is then completed. Note that the heating resistance wires between adjacent installed panels are successively connected as they are being installed.

〔Effect of the invention〕

As described above, in the present invention, even when the floor surface is uneven, the height of the support metal fitting can be easily and accurately adjusted (varied) using the adjustment metal fitting, so that it is possible to easily level the horizontal part of the support metal fitting. In particular, since the lower side edge of the floor panel can be supported over its entire length by the long support bracket, the load acting on the floor panel can be distributed and supported as a whole. The floor panel will not loosen or bend even if a large load is applied to the panel from the top side. Therefore, when a ceramic floor heating panel is used as a floor panel, it is possible to reliably prevent the heat-generating resistance wire from being mechanically cut and the base from being broken.

In addition, since the support bracket has a projecting wall located at the center of the horizontal part of the support bracket, if you place the panel as a guide on the projecting wall, you can speed up the work and at the same time The distance, or in other words, the joint dimensions between panels, is automatically arranged in an orderly manner, resulting in a beautiful finish.

Further, since the lower part of the joint to be formed is closed by the protruding wall, leakage of the joint filler filled into the joint from below is prevented, and the joint filling work can be performed easily and quickly.

Furthermore, the support fitting can be disassembled into a receiving fitting, an installation fitting, and an adjustment fitting, and these fittings can be easily reassembled at the installation site, so that the whole can be compacted, which is convenient for transportation. Further, when rearranging the room, the panel can be easily removed and the support fittings can be easily disassembled.
