Description

  The present invention relates to a wet floor heating and bathroom heating in a detached or high-rise concrete building, a construction method of a wet hot water heating facility laid on a road in a cold region, and a piping grip base used therefor.

In recent detached houses and high-rise concrete buildings, floor heating is used instead of conventional coolers and heating devices from the viewpoint of improving the efficiency of housing space and improving living quality, or as part of health measures for the elderly There is an increasing tendency to install heating equipment in the bathroom.
These heating facilities are constructed by laying a cross-linked polyethylene pipe through which hot water is circulated and then burying it by placing a cleat, on a 910 mm × 1820 mm and 25 mm thick styrofoam 21 as shown in FIG. 7mm, 10mm, 13mm, 16mm and 20mm diameter cross-linked polyethylene pipes 23 are supported by wire-like binding wires 24 on a 1000mm x 1000mm or 1000mm x 2000mm square 100 or 150 pitch wire mesh After laying, the concrete is often placed in the concrete and floored.
For bathroom heating, a 7 mm, 10 mm diameter cross-linked polyethylene pipe 23 is arranged in order as shown in a clipboard 25 made of foam plastic as shown in FIG. The polyethylene pipes 23 are arranged in a reciprocating manner that reciprocates in parallel. In the clipboard 25, protrusions 26 of 17 mm in total height 42 mm are arranged vertically and horizontally on a plane of 600 × 840 mm square, and by arranging the crosslinked polyethylene pipes 23 in a predetermined shape between these protrusions 26, Construction of the cross-linked polyethylene pipe 23 is carried out.
In the construction process, the clipboard 25 on which the above-described crosslinked polyethylene pipes 23 are arranged is laid on a bathroom slab with a moisture-proof sheet interposed therebetween, and then a welded wire mesh and mortar are placed, and then tiles and marbles are formed using empty kneading. Etc. Floor finish.
Furthermore, it has recently been adopted for cold roads and is used to reduce snow removal costs by melting snow on the roads. Construction on the road basically adopts one of the above-mentioned methods, and the following problems are also concerned.
Conventional wet hot water heating facilities have been constructed as described above, but the following problems have been pointed out in detached rooms and bathrooms.
1. Since the welded wire mesh to which the cross-linked polyethylene pipe is attached is 100 pitch or 150 pitch, in addition to the weight of the welded wire mesh being bulky, 7mm, 10mm and 16mm diameter cross-linked polyethylene pipes can be bound to 100 pitch welded wire mesh. However, 13 mm and 20 mm diameter cross-linked polyethylene pipes can only be laid with a 150-pitch welded wire mesh, which is cumbersome to handle and has poor construction efficiency.
2. The support fixed to the welded wire mesh with a wire-like tie wire is suitable for the crosslinked polyethylene tube because of the danger of injury caused by handling the heavy welded wire mesh and the crosslinked polyethylene tube is a resin product. On the other hand, there is a risk of damaging and perforating due to binding wires when piping.
3. Since the clipboard for bathroom heating only arranges the cross-linked polyethylene pipes at a pitch determined by the pipe diameter, and does not firmly support and fix them, when the arrangement pitch reaches 120 mm, the cross-linked polyethylene pipes may rise. The setting position becomes unstable and the overall construction efficiency of the cross-linked polyethylene pipe is poor.

  The present invention improves the conventional problems of wet floor heating and bathroom heating in detached buildings or high-rise concrete buildings, and wet hot water heating facilities laid on roads in cold regions, and is easy to handle and diverse. The construction method of the wet-type hot water heating facility which improved the construction efficiency of the cross-linked polyethylene pipe and the piping grip base used therefor are provided.

  The construction method of the wet hot water heating facility according to the present invention provides a pipe grip base having a required dimension in which pipe grips for sandwiching a hot water radiator pipe are vertically and horizontally installed, and then lays a plurality of pipe grip bases in a construction area. Before and after the hot water radiating pipe is sandwiched between the pipe grips, the hot water radiating pipe is arranged in a prescribed form along the specified piping pitch, and the subsequent construction work is carried out.

  The first piping grip base according to the present invention is used in the construction method of the wet hot water heating facility, and includes a base having a predetermined external dimension and thickness, and an intersection formed by the left and right and upper and lower reference lines of the base. And a plurality of grip openings formed around the piping grip and sandwiching the hot water radiator pipe.

  In the second pipe grip base according to the present invention, adjacent pipe grips in the first pipe grip base are connected by a reinforcing member that does not interfere with the pipe of the hot water radiating pipe.

  The third pipe grip base according to the present invention is a foam plastic base having a thickness that is sufficient to exhibit the heat insulating effect of the hot water radiating pipe in the first and second pipe grip bases.

The construction method of the wet hot water heating facility according to the present invention is easy to handle because the piping grip base for supporting and fixing the hot water radiator pipe is a resin product, and there is no risk of injury to the worker or damage to the hot water radiator pipe and hole opening. Since the route pitch of the hot water radiator pipe is stabilized, the overall construction efficiency is improved and the cost is reduced.
The first piping grip base according to the present invention can be fixedly supported without using a wire-like binding wire for attaching the hot water radiating pipe to the welded wire mesh when used in the construction method of the wet hot water heating facility. Since it is a resin product, it can be handled lightly, and at the same time, there is no risk of scratching and opening of the hot water radiating pipe, so that the construction work can be easily performed.

  The second piping grip base according to the present invention can secure the strength of the piping grip without limiting the pitch of the hot water radiating pipe in addition to the effect exhibited by the first piping grip base. Has the effect of facilitating.

  The third pipe grip base according to the present invention is laid down at the lower part because the thickness of the base is adjusted to a value capable of exerting a heat insulating effect in addition to the effects exhibited by the first and second pipe grip bases. There is an effect that the cost can be reduced without doing so.

The construction method of the wet hot water heating facility according to the present invention is to prepare a pipe grip base of a required dimension in which pipe grips for sandwiching a hot water radiator pipe are vertically and horizontally installed, and then construct a plurality of pipe grip bases. Before and after laying in the area, place the hot water heat radiating pipe in the specified form along the specified piping pitch while holding the predetermined hot water radiating pipe between the individual pipe grips, and then perform the subsequent construction work Is.

In the construction of wet hot water heating facilities, a hot water radiator pipe is installed inside the floor of a living room or bathroom, and the warm water is circulated through the hot water radiator pipe to raise the floor of the living room or bathroom to a desired temperature. Therefore, it is most difficult to arrange hot water radiator pipes, and even when installing hot water radiator pipes, a single welded wire mesh is installed throughout the construction area according to the scale of the construction site. There are a case where the hot water radiating pipe is supported and fixed, and a case where the construction area is divided and a plurality of piping grip bases are connected and arranged.

First, 1000 mm × 1000 mm square or the like as shown in FIG. The piping grip base 1 divided into the required dimensions is prepared. In addition to this, the external dimensions of the piping grip base are arbitrarily selected according to the size of the construction area, the diameter of the hot water radiating pipe, and the arrangement pitch, such as 1050 mm × 1050 mm, 1200 mm × 1200 mm.
In this pipe grip base 1, pipe grips 3 having a structure as will be described later are planted vertically and horizontally as shown in the figure in order to sandwich the hot water radiation pipe 2. The planting pitch of the pipe grip 3 is constituted by intersections formed along reference lines for sections virtually divided on the upper and lower sides and the left and right of the pipe grip base 1 divided into required dimensions. In consideration of the environment and dimensions, the pitch is determined to be an arbitrary pitch such as 100 mm, 150 mm, 200 mm, or 300 mm.
The piping grips 3 are connected to each other by a reinforcing member 4 having a configuration that does not hinder the arrangement of the hot water radiating pipe 2, and the piping grip 3 that sandwiches and fixes the hot water radiating pipe 2 is mechanically connected by the hot water radiating pipe 2. It is reinforced to prevent it from being knocked down.

It is firmly fixed without using other members.
Further, when the arrangement direction of the hot water radiating pipe 2 is changed at the upper and lower ends of the pipe grip base 1, the reinforcing member 4 extending in the left-right direction of the pipe grip 3 planted at the end portion is arranged. The hot water radiator pipe 2 is crossed so that the hot water radiator pipe 2 passes through, and at the same time, the curved portions 9 and 10 of the hot water radiator pipe 2 are held in the holding ports 7 and 8 positioned in the vertical direction, so that the hot water radiator pipe 2 is replaced with another member. We support without using.
As described above, the construction method of the wet hot water heating facility according to the present invention is constructed without using a welded wire mesh or a wire-like binding wire to support and fix the hot water radiator pipe. The piping grip base that supports and fixes the radiator pipe is a resin molded product that is lightweight and easy to handle, and there is no risk of operator injury, hot water radiator pipe damage or hole opening, and the pitch of the hot water radiator pipe Since the route is stable, the overall construction efficiency is improved and the cost is reduced.
The first to third piping grip bases according to the present invention are all used in the construction method of the above-described wet hot water heating facility, and have predetermined outer dimensions and thicknesses constituting the first piping grip base. Based on the base, the piping grip that is planted at the intersection composed of the left and right and upper and lower reference lines of the base, and a plurality of grip openings that are formed around the piping grip and sandwich the hot water radiator pipe, The adjacent pipe grips are connected with a reinforcing member that does not interfere with the piping of the hot water radiator pipe (second pipe grip base), and the thickness is a value that exhibits the heat insulation effect of the hot water radiator pipe. It is improved by constituting from a base made of foamed plastic (third piping grip base).

Therefore, only the characteristic features will be described by omitting the overlapping parts.
As shown in FIG. 2, the piping grip base 1 according to the present invention is divided into required dimensions such as 1000 mm × 1000 mm square according to the conditions of the construction area. Correspondingly, 1050 mm × 1050 mm and 1200 mm × 1200 mm square are appropriately selected.
In this pipe grip base 1, pipe grips 3 for sandwiching the hot water radiation pipe 2 are implanted vertically and horizontally as shown in the figure. The installation pitch of the pipe grip 3 is configured at intersections formed along reference lines imaginary on the upper and lower sides and the left and right of the pipe grip base 1 divided into required dimensions, and the hot water radiating pipe 2 is 7 mm and 10 mm. In the case of the diameter, a pitch of 100 mm is selected, and when the diameter of the hot water radiator pipe 2 is 13 mm, the pitch is 150 mm, the pitch is 16 mm, the pitch is 200 mm, and the pitch is 20 mm, the pitch is 300 mm.
Since each piping grip 3 is constructed sequentially according to the design drawing in the vertical and horizontal directions of the piping grip base 1 as shown in FIG. The hot water radiating pipe 2 is firmly configured so as to be securely fixed without using any other member only by holding the hot water radiating pipe 2 into the holding ports 5 to 8 formed in the vicinity thereof against the applied pressure from the outside.
Further, the piping grips 3 are configured such that even if they intersect when the hot water radiating pipe 2 is arranged, the piping grip 3 protrudes from the height of the piping grip 3 so that the stable arrangement of the hot water radiating pipe 2 is not hindered. The pipe grips 3 sandwiching the hot water radiating pipe 2 are maintained so as not to be collapsed by the hot water radiating pipe 2 when the concrete is placed.

Since the shape of the mouths 15 to 18 is configured to securely fix the hot water radiator pipe 2 without using any other parts, the tip 19 of the mouths 15 to 18 has a hot water radiator pipe. At the same time, the circular portion 20 formed at the lower portion thereof is configured to be slightly larger than the tail opening of the tip 19. The size of the opening formed at the tip 19 and the size of the circular portion 20 are selected according to the size of the diameter of the hot water radiator pipe 2 to be arranged and the size of the pitch to be arranged. When the pitch for arrangement is 7 mm, 10 mm, and 100 mm, a common pipe grip base in which the size of the opening formed in the tip 19 and the size of the circular portion 20 are the same can be used. When the diameter of the hot water radiator pipe 2 is 13 mm and the pitch for arrangement is 150 mm, another different pipe grip base having a different opening size and circular part size from the above pipe grip base is selected. Will do. Similarly, a pipe grip base having a pitch of 200 mm is selected when the diameter of the hot water radiating pipe 2 is 16 mm, and a pipe grip base of 300 mm is selected when the diameter is 20 mm.
