Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a structure of a roofing base material which is used for floorboarding and which never leaks rain.

(B) Conventional technology and its problems If the roofing material is roof tiles, the roof tiles will be nailed to the tarpaulin through the tarpaulin and the field board, and the tarpaulin will have many holes with nails. So, the rainwater that entered from the roof material flows from this hole (the gap between the nails nailed and the tarpaulin) onto the base plate, and because there is a slope on the roof, it flows downwards,
Since there is a gap between the joints of the field boards, it leaks from here. In addition, since this rainwater has a slope between the top of the field board and the attic under the field board, it flows downward and has a final dead end (roof frame). There is a stop (roof frame) at the junction of (field board and roof frame) Stops at the junction of (field board and roof frame), and rainwater accumulates on the eaves below. Also, rainwater flows downward between the floorboard and the tarpaulin, but also falls directly under the floor, but most of it flows down the backside of the floorboard, but the greatest rain leak occurs when the roof tile is placed on the tarpaulin. Since there is a gradient of rainwater that entered from the gap between the above, it flows downwards a lot (through the sheet), stops at the joint between the roof frame and the roof plate, and flows to the eaves, and in this case a large amount of rainwater accumulates on the eaves. Therefore, the leak from the roof is the place where the leak from the joint between the roof frame and the roof plate is maximum.

When the roofing material is roofing iron, the roofing iron is fixed to the roof with a tarpaulin through a tarpaulin and a ground plate. Therefore, a large number of nail holes are formed in the waterproof sheet, and rainwater that has entered from the roof material leaks from the joint portion between the base plates as in the case of the roof tile.

When the roofing material is asbestos slate board, a tarpaulin is put on the base board and the asbestos slate board is nailed to this base board. With this nail, a number of nail holes are made in the tarpaulin, and the roofing material is used. Rainwater leaks from the joints between floor boards, as in the case of roof tiles and roof bar tin.

In addition, there is a gap between the roof frame and the base plate, and rainwater flows over the waterproof sheet and flows on the back surface of the base plate (downward). A large amount of rainwater accumulates on the eaves from these gaps, and the eave boards and taros are currently rotten.

The eaves, eight plates, pillars, etc. rot due to rain. Also, since the amount of humidity increases, there are various problems such as not only rain leaks even if the house that causes termites is completed, but also hot air cold air humidity easily enters the room from the gap between the joints of the base plates. It was happening.

The present invention is intended to eliminate the above-mentioned drawbacks and to obtain a structure of a roofing base material that does not leak rain for a long period of time. By paying attention to the nature, the temperature under the roof tiles in summer, and the relationship between nails and rain leaks, the above defects were removed at once, and a complete roofing underlay structure that does not leak for a long period of time was obtained.

(C) Means for solving the problem and its action In the structure of the conventional roofing substrate, the joint part (5) is filled, and the tape (17) is stuck on it. The underlying structure of the roofing is the technical means of the present invention.

The present invention will be described in more detail.

The film (tape) used in the present invention is called a non-adhesive tape on both sides of which the adhesive is not applied, and the filling material of the present invention is a viscoelastic type or viscoplastic type non-membrane type (non-drying filling material). ), A viscoelastic type, and a viscoplastic type (filler that dries for a long period of time), and a film (tape) (non-adhesive tape) is applied.

Particularly noteworthy is that the above-mentioned (non-adhesive tape) together with the above-mentioned non-membrane type (non-drying filler or membrane type (for a long period of drying) filler) with the viscosity of the filler (non-adhesive tape ) Is in an adhesive state.
The inventor used the viscosity of the above-mentioned filler instead of the adhesive, in that the adhesive tape normally described in the specification of No. 35137 cannot withstand the summer temperature (80 ° C) under the roof tile ( I applied non-adhesive tape (on top of the filler).

The filler used in the present invention is a viscoelastic type or viscoplastic type non-membrane type, or a viscoelastic type or viscoplastic type film type. These fillers are paste-like and do not flow and fall during summer roof tiles. It withstands a lower temperature of 80 ° C (it is described in the literature that the temperature under the roof tile in summer can reach 80 ° C). Also, if the elasticity due to the temperature difference of the base plate is not accompanied by the elasticity due to the temperature difference of the filler, or if it cannot withstand it, the filler will be damaged, but the properties of these fillers are viscoplastic and stretchable. Since it has great properties and can withstand the expansion and contraction of the base plate, it will not be damaged even if it is used in a concave groove. In addition, one type of viscous oil-based caulking film type is a non-adhesive tape for preventing drying, which is applied on the filling material of the groove to make use of the sticky viscosity of the filling material to form a paste with high viscosity. It remains a paste for a long time. Also, by attaching a non-adhesive tape for preventing the drying of the viscoelastic type filler, the viscoelastic type filler can be maintained in a viscous paste state for a long time without being elastic. (It is described in the literature that the filling material used in the present invention has the above-mentioned properties.) Also, the tile groove mounting nail, the roof tile galvanized iron mounting nail, and the asbestos slate plate mounting nail are used as the groove filling material,
Even if the nails are nailed to the slacker through the grooved floorboard, the nails are firmly held in the paste form (softness) of the filler, and the contact between the nail and the non-adhesive tape for preventing drying is the filler to the air. By touching, the film surrounds the nails and becomes clumped, so that the inside of the filler can retain its initial flexibility. Since the filler used in the present invention has a soft state (paste state), it can be nailed. The viscoelastic filler used in the present invention is a one-component silicone type (JIS575
5), polysulfide type, acrylic type, butyl rubber type, silicone type, polysulfide type (thiocol) (JIS5754), rubber epoxy etc. in the two-component type, but the viscoplastic type filler is film type oily caulking and surface There is an oil-based caulking that is coated with
The filling material must comply with JIS standards.

For the base plate, veneer, plywood, fiberboard, particle board,
Examples include Trizol board, plastic board, hard wood chip cement board, aerated concrete board, etc. There are various JAS standard products, but they must be water resistant and waterproof. Conventionally, the plywood field boards include structural plywood special type and type I (concrete panel) (control panel), but are not limited thereto. Regarding the thickness, if the thickness is 9 mm or less, it is not appropriate due to the flexibility of workers when gathered on top and the weight of the roof material, and 12 mm or more is preferable, but the size is not limited. However, if the slap is under the horizontal joint, 9mm is acceptable.

Non-adhesive tapes for preventing the filler from drying include, but are not limited to, vinyl tapes, plastic film tapes, and Teflon tapes.

There are many shapes of the concave groove in the related art, and the shape will be described in the embodiment, but the shape is not limited to this. Further, the formed groove can be filled with a thick layer of filler. Therefore, the function of the filler can be fully utilized.

(D) Embodiments Embodiments of the present invention will be described in detail with respect to the base plate, the filler, the membrane (tape) and the groove mold.

(1) Examples of the field boards include, but are not limited to, veneer, plywood, fiber board, particle board, hard wood cement board, and aerated concrete board.

If you use a baseboard that does not rot even if it leaks directly to the rain (for example, special structural plywood), it will not rot and you will not need to attach a waterproof sheet. No doubt, the inventor is willing to do this, but is not limited to this. If a type I board is used, a waterproof sheet must be attached. Since there is a waterproof sheet above, I would say that it rots if it has only a type I base plate (waterproof).
If rainwater enters between the plywood and the tarpaulin, it will not dry, so it will rot quickly, so it is necessary to attach the tarpaulin to the above type I items. Other field boards, veneers, fiber boards, particle boards, hard wood chip cement boards, aerated concrete, etc. are all things that rainwater can pass through even if the joint is filled. It's no good. Therefore, only the joint between the base plate, the roof frame and the base plate is filled, and the waterproof sheet is pasted on it. Then, assuming that the number of rain leaks in other places is 1, the distance from the joint between the roof frame and the base plate is about
It rains ten times. Next, the filling material will be described. The viscoelastic type and the viscoplastic type are optimal, but the filling material will not be damaged even if the nail is punched where the filling is performed later. Also, it is not limited to this as long as it can withstand heat, and it is not limited to this. The above-mentioned filler has non-film property (does not dry) and film property (does not dry for a long time). Either is acceptable. However, there are some differences in prices. When filling, a tubed or extruded type (those that come out of cardboard), an extruder that comes out of metal and put in the tube and extruded, and one that puts it directly in the extruder without putting it in the tube There is also a method of feeding by pressure and filling with a hose. This is very efficient. This is a specialized case, and other materials can usually be used. However, it is also important to note that the waterproof sheet is mainly made of paper such as pitch-based liquid that comes out of coal tar and chemically treated, but vinyl is also available. The system is vulnerable to heat and cannot be used. Also, the most widely used tarpaulin (tar-based asphalt roofing) is good, but since all the above fillers are also put on the asphalt attached to this asphalt roofing, it cannot be used. It will not be a problem if the combined filler is used. Therefore, in this case, if the asphalt-based filler is used, the asphalt-based filler may be used, but the filler is not limited to this, and either the waterproof sheet or the filler may be used. In other words, it is the use of both things that cannot be messed up. However, if you use a non-adhesive tape (one without adhesive on both sides), the tape will not be placed on the filling material or waterproof sheet (asphalt roofing). Any of these can be used (with a tape in between). There are oil-based caulks, butyl-based sealants, mastic type silicones, etc. as the above-mentioned fillers, but they are divided into several types. What kind of fillers should I use depending on where they are used? teach.

Next, examples of the groove mold will be described. Grooves are conventionally formed in FIG. 2, 3, 4, 5, 5, 6 or 7 of the drawings.
Although FIG. 8 and FIG. 8 are conventional, the present invention is not limited to this and any one may be used.

Next, the implementation of the tape will be described in detail. The present inventor refers to a tape as a film, and the film is a tape. First, we will describe the types of tapes that are sold. If you buy it from Nitto Denko, double-sided non-adhesive tape NO.900.N
O, 970 NO.920. Single-sided adhesive treatment tape NO.901.NO.971.NO.9
21, adhesive tapes No. 903, No. 923, etc., but not limited to these, the H-face adhesive treated product is not stuck on the filler in the present invention. This is to use structural plywood to temporarily bond the double-sided non-adhesive tape to the field board wider and wider than this tape, and to use both sides of the double-sided non-adhesive tape with this single-sided adhesive treatment tape. It is a place to attach to the dust filling material very much, but since the adhesive does not reach the temperature of the roof in summer of 80 degrees Celsius, it is temporary, and in the case of roofing etc. This is to prevent the roof tile powder and other debris from sticking to the filler when cutting, but it is temporary and does not get wet. After that, even if the tape is damaged by heat, the lower double-sided non-adhesive tape is attached by the adhesive force of the filler, and the filler is not exposed to heat, so that the rain does not leak for a long time.

However, the ground board is plywood type I (control panel) or plywood or fiber board of this degree, particle board or hard wood chip cement board, aerated concrete or anything similar that water can pass through without using a waterproof sheet. Don't If you don't attach a tarpaulin, rainwater will pass through and it will rain (even if it doesn't rot). (Except for structural plywood) Therefore, if the above-mentioned filler is used, the filler will be put on the resin attached to the waterproof sheet and will cause rain leakage, so by applying a non-adhesive tape on this filler, the waterproof sheet This tape is applied so that the filler is not placed on the asphalt or other resin that has been left unattended.
In addition, since double-sided non-adhesive tape is applied because dust does not deteriorate the performance of the filling material. Also, with adhesive tape, the adhesive applied to this adhesive tape cannot withstand the temperature of the summer under the roof, so instead of this adhesive, use the adhesive strength of the filler that can withstand temperature and use a double-sided non-adhesive tape. Stick it. In short, if you use a waterproof sheet, you cannot use a waterproof sheet unless you use double-sided non-adhesive tape. In addition to the above-mentioned characteristics when using a double-sided non-adhesive tape when using a film type filler, the gap between the base plate, the filler and one side of the double-sided non-adhesive tape (the lower side facing the filling) Since it will dry out for a long time, it is a filler that dries when exposed to air, so if the gap clogs, the middle part of the filler naturally shuts off the air, so the drying stops at this contact, That is, the properties of the filler can be kept at the initial values and the performance of the filler can be maintained for a long time. The above tape has excellent chemical resistance and a wide operating temperature range. This is explained in detail because the above knowledge is necessary for implementation.

The way to stretch the base plate is the same as the conventional way.

It is stretched from the corner of the roof.

By arranging the roof frame 18 and the base plate 1 adjacent to each other like the conventional tensioning method (first sheet), the base plate 1 of the present invention has a joint portion between the base plates as shown in FIG. 1 of the drawings. A groove 3 is formed in the joint portion 5 between the roof 18 and the base plate 1 by opening. Then, as in the conventional method of tensioning the second board 1, the board 1 and the board 1, and the roof frame 18 and the board 1 are placed adjacent to each other.

Next, the filling material 4 used in the present invention is thickly filled in the groove 3 and the non-adhesive tape 17 for preventing the drying of the filling material is stuck thereon.

(E) Effect of the present invention (1) The joint is completely sealed by the filler used in the present invention that is paste-like (soft) and withstands the elasticity of the base plate, so rainwater flowing from the roof material Even if it flows onto the ground plane, it will not leak from the joint.

(2) The filler used in the present invention is paste-like (soft)
So, through the filling material of the groove of the joint, the base plate of the groove,
Even if the roof tiles and roofing materials are nailed to the slack, there is a place where the roof tiles, roof tile corrugated iron roof, and asbestos slate roof do not come into contact with the roof tiles and roof material mounting nails. Even if a nail comes in, rain will not leak from the joint.

(3) Since the joint is sealed with a filler that withstands the temperature under the roof tiles in summer and does not change its properties for a long time, it does not leak rain for a long time.

Therefore, it is possible to prevent the eaves, eight plates, pillars, etc. from rotting, the Moultar wall from cracking due to rain leaks, the inner plate of the outer wall from rotting, and moisture to cause termites to attach. or,
It can prevent hot air, cold air, and humidity from entering the room, and it is cool in summer and warm in winter, which saves energy.

(4) Even if the roof tiles are blown by a typhoon or the roof material is damaged by an earthquake, the joint is fully sealed with the filler used in the present invention, so there is a gap between the conventional roof frame and the ground plate. Therefore, it was solved that there was a lot of rain leaks from here, and it did not leak even if there was no roofing material because it completely prevented rain leaks.

(5) The filling material used in the present invention does not break for a long time, the groove of the joint is filled, and non-adhesive tape for preventing dryness and dust is stuck on the groove, so that the function of the filling material is initially flexible in the long term. Because it can maintain sex, it will not leak in the long run.

(6) When using a board with weak water resistance, a waterproof sheet must be used. However, the tar-based resin, which is heavily impregnated in the waterproof sheet, causes the filler to be filled. Therefore, by sticking the double-sided non-adhesive tape between the filling material and the waterproof sheet, the tape is not placed on the filling material or the resin of the waterproof sheet, so that even if the waterproof sheet is used, rain leakage can be completely prevented.

However, if the filler is a tar-based one and a tar-based waterproof sheet is used, neither the waterproof sheet nor the filler can be used without a tape. However, since the waterproof sheet and the filler are hermetically sealed, if rainwater enters the other space, it will not dry and will rot because there is no room for it to escape. Therefore, even in such a case, the use of the double-sided non-adhesive tape eliminates the problem.
