Description

[Detailed description of the invention] (Industrial field of application) The present invention relates to a mold for the grille mounting groove in an air conditioning practical sleeve in which a grille (bend cap) is attached to the outdoor opening of the sleeve body. .

(Prior art) In the air conditioning sleeve, the sleeve body is buried in the wall of a building for indoor air conditioning, and the outdoor opening of the sleeve body is designed to prevent pests such as rats and birds from entering and to prevent rain. A grill is installed for this purpose.

As a structure for attaching the grille to the sleeve body of this air-conditioning sleeve, for example, the structure shown in FIG. 5 is known.

This conventional air conditioning sleeve 50 has a sleeve main body 52 buried in a concrete wall 51, and an outdoor end surface 53 of the sleeve main body 52.
is formed to have a uniform surface with the outer wall surface 54 of the concrete wall 51, and the grille 56 is fitted into the outdoor opening 55 of the sleeve main body 52 with the flange 57 facing the outdoor end surface 53, and the flange A caulking material 58 is placed between the 57 and the outdoor end surface 53.
It was constructed with a seal.

(Problems to be Solved by the Invention) However, in the conventional air conditioning sleeve 50, the outdoor end surface 53 of the sleeve body 52 is formed to be a uniform surface with the outer wall surface 54 of the concrete wall 51. Since the structure is such that the flange 57 of the grill 56 is in contact with this outdoor end surface 54 and sealed with a caulking material 58 from above, this caulking part is formed on the outer wall surface 54 of the concrete wall 51. It will end up being put away.

Therefore, if the caulking material 58 deteriorates,
There is a problem in that raindrops traveling on the outer wall surface 54 enter between the flange 57 and the outdoor end surface 53 and flow into the sleeve body 52 from there.

Further, since the caulking portion is formed in a protruding state on the outer wall surface 54, there is a problem in that the appearance is unsightly and the appearance is significantly spoiled.

That is, conventionally, when constructing a formwork when embedding the sleeve body 52 in the concrete wall 51, the outdoor end surface 53 of the sleeve body 52 was directly fixed to the formwork panel.
The outdoor side end surface 53 of the concrete wall 51 is formed in a uniform plane with the outer wall surface 54 of the concrete wall 51. As a result, when the grille 56 is installed, the caulking part is exposed in a protruding state on the outer wall surface 54, resulting in the above-mentioned problem. This was causing problems.

(Means for solving the problem) The present invention was devised to solve the conventional problems as described above. , a practical sleeve for air conditioning in which a grille is attached to the outdoor opening of the sleeve body, which can be attached and detached to the outdoor opening of the sleeve body during formwork construction when embedding the sleeve body in a concrete wall. A mold for a grille mounting groove that is attached to a sleeve body, the molding mold for a grille mounting groove includes a cylindrical body that is removably fitted to the inner periphery of the outdoor opening of the sleeve body, and an outer periphery of the outer end of the cylindrical body. The sleeve body is provided with an elastic ring that is removably attached between the outdoor end surface of the sleeve body and the formwork panel.

(Function) In this invention, when constructing the formwork when embedding the sleeve body in a concrete wall, an elastic ring is interposed between the outdoor end surface of the sleeve body and the formwork panel. is removably attached to the sleeve body, so when the mold is removed after the formwork is constructed and the concrete wall is poured, the elastic ring will be attached to the outer wall surface of the concrete wall. As a result, a recessed portion serving as a grille mounting groove is formed between the sleeve body and the outdoor end surface.

Therefore, inside this grill mounting groove,
If the flange of the grill is brought into contact with the outdoor end surface of the sleeve body and the caulking material is filled from above to fill the grille mounting groove, this caulking part will be formed inside the grille attachment groove.
I have never experienced a case where the caulking part protrudes from the outer surface of a concrete wall.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

The mold A for grill attachment grooves (hereinafter referred to as the "mold") of this embodiment is used to attach the grill 3 to the outdoor opening 21 of the sleeve body 2 which is embedded in the concrete wall 1. The air-conditioning practical sleeve B thus constructed is used when constructing a formwork when embedding the sleeve main body 2 in a concrete wall 1.

The sleeve main body 2 is formed into a cylindrical body with a length slightly shorter than the wall thickness of the concrete wall 1 using a galvanized iron plate, and a flange 23 is formed along the outer periphery on the outdoor end surface 22. Three mounting brackets 24 are fixed to the outer peripheral surface in a state protruding from 23, and reinforcing beats 25 and 26 are formed in an annular shape in the circumferential direction in the middle,
Of these, the reinforcing beat 25 closer to the outdoor side is formed into an inwardly directed protrusion, and serves also as a water stopper against the inflow of water from the outdoor opening 21.

The grill 3 is attached to the outdoor opening 21 of the sleeve body 2 buried in the concrete wall 1 to prevent pests from entering and to prevent rainwater. It is formed into a cylindrical body that fits on the inner circumference of the sleeve body 2, and has a plurality of armor plates 32 provided at the outer end opening 31, and a flange 33 formed in the circumferential direction on the outer circumferential surface in the middle. .

Next, the mold A is composed of a cylindrical body 4 and an elastic ring 5.

The cylindrical body 4 is formed of a galvanized iron plate and has an outer diameter that allows it to be removably fitted to the inner circumference of the outdoor opening 21 of the sleeve body 2, and has a flange 41 formed around its outer end.

Further, the elastic ring 5 is formed as a circular rubber ring with a square cross section, and is fitted onto the outer circumference of the outer end of the cylindrical body 4.

Next, the operation of this embodiment will be explained.

The order of construction of the actual air conditioning sleeve B is to first embed the sleeve body 2 in the concrete wall 1, and when constructing the formwork, as shown in Fig. 1, the cylindrical body 4 of the mold A is inserted into the sleeve. The elastic ring 5 is removably fitted into the outdoor opening 21 of the sleeve main body 2, and the elastic ring 5 is connected to the flange 23 which becomes the outdoor end surface 22 of the sleeve main body 2, and the outer formwork panel 6.
and in this state, the elastic ring 5
Nail 7 from mounting bracket 24 through
By driving into the outer formwork panel 6, the mold A
The outdoor side end surface 22 of the sleeve body 2 is fixed to the outside form panel 6 via the sleeve body 2, and then the inner form panel 8 is set on the indoor side end surface 27 of the sleeve body 2.

After constructing the formwork in this way, concrete is placed inside it, and after this solidifies, the formwork is removed from the form.In this case, first, the inner and outer formwork panels 8, 6 are removed, and then the forming When the mold A is removed, the sleeve body 2 is buried inside the concrete wall 1 as shown in FIG. A recess that will become the grille attachment groove 12 is formed between the grille and the outdoor end surface 22 of the grille.

Next, the grill 3 is attached to the sleeve body 2 buried in the concrete wall 1 as described above. In this case, as shown in FIG. While fitting into the outdoor opening 21, the flange 3 of the grill 3
3 is brought into contact with the flange 23 of the sleeve body 2 inside the grill attachment groove 12, and in this state, the inside of the grill attachment groove 12 is filled with caulking material 9.

Therefore, in the air conditioning sleeve B of this embodiment, the grille mounting groove 12 is formed in the outer wall surface 11 of the concrete wall 1, and the flange 33 of the grille 3 is connected to the flange of the sleeve body 2 inside the grille mounting groove 12. Since the caulking material 9 can be filled in the grille mounting groove 12 from above and facing the grille mounting groove 12 , a caulking part is formed inside the grille mounting groove 12 , and this is formed on the outer wall surface 11 of the concrete wall 1 . There has never been a time when it stood out from the crowd.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration of the present invention is not limited to the above-described embodiments, and the present invention may be modified without departing from the gist of the invention. included in the technical scope of the invention.

For example, the mold in the example is applied to a cylindrical air conditioning sleeve, but it can also be applied to a rectangular cylinder, in which case the cylinder is formed into a rectangular cylinder. do.

Further, the elastic ring is not limited to a rubber ring, but may be a synthetic resin ring.

Regarding the groove structure for attaching the grille to the sleeve body, in addition to the structure of the embodiment, an expandable nut is provided inside the sleeve body, and a bolt passed through the grille is tightened to the expansion nut to further strengthen the grille. It may be installed.

The sleeve for air conditioning can be used for various purposes, such as for ventilation in kitchens and toilets, and for exhaust from instantaneous water heaters in the kitchen.

In addition, due to construction reasons, when the actual air conditioning sleeve is passed through a thick part of the wall, such as a beam protruding into the room, it is necessary to make the sleeve body long. Preferably, the extension sleeve is slidably connected in the axial direction to the inner end of the sleeve main body, so that the length of the sleeve can be expanded and contracted depending on the wall thickness.

In addition, if the actual sleeve for air conditioning is located far from the ventilation fan in the room, connect the exhaust port of the ventilation fan and the sleeve body to a PVC pipe duct or spiral duct installed in the ceiling etc. Rotate and connect.

(Effects of the invention) As explained above, according to the invention, when embedding the sleeve body in a concrete wall, the grill mounting groove can be formed on the outer wall surface of the concrete wall using a forming mold. If you fit the grill flange to the end face of the sleeve body inside this grill installation groove and fill the caulking material from above to fill the grill installation groove, the caulking material will not protrude from the external wall surface of the concrete wall. can be formed inside the grille mounting groove.

As a result, even if the caulking material deteriorates or the caulking fails, there will be no chance of raindrops entering between the grille and the sleeve body, and the unsightly appearance caused by the caulking protruding from the outer surface of the concrete wall. By eliminating this problem, you can create a clean appearance.
