Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is firstly used for new construction of a house having a gable roof, and secondly used for re-roofing a roof.

The present invention generally relates to a roof ventilation structure for a house, and more particularly to a ventilator provided in a roof ridge portion.

[0003]

2. Description of the Related Art It has long been known that ventilation is provided in the attic under a gable roof by providing ventilation holes along the roof ridge. In this type of ventilation, the top row of roofing boards is opened during construction to form an opening slot that is substantially the length of the roof. This opening slot creates effective thermal ventilation by the convection inside the room and the suction effect of the wind that crosses the roof ridge.

[0004]

The Sofit ventilator is provided with a hole or an armored opening on the lower side (Sofit) of the roof ridge that protrudes. This ventilator allows fresh air to enter the attic and equalize the temperature and pressure in the room with that of the outside. This leveling action precludes the buildup of ice that can cause mold and decay on the insulation and wood roofing material or destroy shingles and gutters. The warm attic air then replaces the cold atmosphere, saving air conditioning costs.

The Sofite ventilation system forms passive ventilation with ridge ventilation. The warm old air is drawn out of the ridge slots by convection and / or wind suction, after which fresh air is supplied through the Sofit ventilator.

[0006] The difference between the various types of ridge ventilation is basically due to the lid structure for preventing water and pests from entering the ventilation hole. Early lid structures, often referred to as "metal covers" or "ridge covers," were longer than slots to form a baffle and net combination to prevent ingress of water and pests. A typical example is U.S. Pat. No. 2,214,183 (Seymour).
And No. 2,160,642 (Bumpass). A more advanced building cover is U.S. Pat. No. 3,683,785.
It uses louvers, as seen in the specifications (Grung) and 4,558,637 (Mason).

Other cover structures place various perforated materials over the slots and other parts of the roof are roofed with roofing material such as shingles or tiles. For example, U.S. Pat.
No. 7 (cell) shows a matrix of synthetic resin molded product or porous corrugated cardboard soaked with epoxy resin liquid, with the side surface open for ventilation of warm air and a shingled plate nailed. Has been done. The relatively large and straight holes in this corrugated cardboard provide an improvement that includes a metal flash strip with a small ventilation hole at least on the windward side as rainwater blown in the wind flows back into the slots. (US Patent No.
4,843,953, cell again). Basically the same thing, which consists of a corrugated polyethylene plate, is shown in U.S. Pat. No. 4,803,813 (Fitterman).

Materials that are smaller and more swirling than corrugated plates are effective in preventing the entry of wind-borne rainwater and small pests. Nonwovens and open-cell plastic foam materials are inexpensive and suitable for use as roof ventilation. U.S. Pat.No. 4,325,290 (Wolfert)
In, a non-woven fabric is used as a filter in a ventilation cap mechanism. In U.S. Pat. No. 4,942,699 (Spinelli), a thin non-woven fabric is applied to a nylon fiber mat and has sufficient structural resilience as a sheet to be used under the roof shingles. U.S. Pat. No. 4,876,950 (Rudine) has two strips of open-cell plastic foam placed parallel to it.
It is used on the underside of roof shingles with the book's impermeable plastic members.

From the above, it is understood that the invention relating to the ventilation of the roof ridge part makes a great progress by the practical application of the new material and the inventor's ingenuity to apply it to the roof ventilation material. Without even displaying a huge list of desirable patents, the ventilation material must have good air circulation enough for thermal ventilation, and must not contain small pests, dust, water, etc. Therefore, materials such as non-woven fabrics and open cell foam rubbers that have small and entrained air flow passages and have coreless properties are good candidates. However, such materials have good elongation strength, durability, and the property of being able to be rolled up or cut in length for transportation.
It must exhibit various other mechanical and chemical properties, such as the ease with which the strips can be connected and the long-term weather resistance under the weather conditions of the land.

In the conventional ventilator described above, the additional properties described above are due to the fact that a sheet of fabric or a strip of foam is laminated to another material, such as nylon mat (Spineli), a plastic film (Rudine). It is achieved by However, these synthetic materials often require that certain properties be compromised for other properties. For example, the nylon mat described in the above-mentioned Spinelli patent, which is formed by laminating a fiber sheet, gives the sheet the required thickness and durability, but impairs the ease of handling. When the roll of laminate is unwound for attachment, nylon mats must be folded back at the edges and lateral overhangs to prevent the ingress of water and pests, and non-woven fabric must be wrapped around the sides of the mat. In order to join the two strips of the laminate together, the nylon mat must be cut open on one of the sheets and then the two sheets must be laminated together and glued together. Further, whether this mat is attached to either side of the central hinge of the sheet, it can be installed upside down by an operator unfamiliar with the material. That is, the sheet is on the upper side of the mat, not on the lower side.

[0011]

DISCLOSURE OF THE INVENTION The present invention provides an improved mat using a mat formed of non-uniform synthetic fiber materials joined with a phenolic or latex based binder to provide a breathable mat with varying mesh. Provide ridge ventilation for a fixed roof. Compared to other ventilation mats, the mat of the present invention has a single sheet structure which is generally made by laminating general sheets or joining them together.

[0012]

In a typical 1360 gram compression test, the preferred standard embodiment mat of the present invention exhibits 100% recovery at 13% compression despite having a thickness of only 5/8 inch. It was The tensile strength is 55 PSI in the longitudinal direction and 64 PSI in the direction intersecting with it. Such a mat is easy to install, cut it from the rolled one to an appropriate length, put it on the slot of the roof ridge, put a shingle or tile on top of it and fix it with nails . If it is necessary or desirable to join the above parts together with a synthetic rubber seal or other suitable cork or glue to join the asphalt shingles and seal around the flushing. You just need to join the ends.

Another example of a mat is the use of heavier roof tiles such as slate and terracotta. In this case, greater compression resistance is required.
This great compression resistance is achieved by arranging liquid polyester (nylon) in a matte fiber on a lattice pattern and forming a solid core body having a diameter of about 1/2 inch at the intersections of lattices at intervals of about 3 inches. Achieved by The dispersed core supports heavier tiles without interfering with ventilation and without compromising the ability of the mat to be rolled and delivered during delivery.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 1, a ventilation system 10 according to the present invention.
Are used to ventilate warm air indoors through slots 12 in the roof ridge. In the first configuration, the slots 12 are approximately 3/4 inch to 1 inch shorter (1 3/4 inch to 2 inches if ridge posts are used) on the upper deck 14 as shown in FIG. Then it is formed by laying on the roof truss slack 15. When the roof plate is already present, leave the sheet plate of the ridge part about 6 inches on the front and back sides of the roof, taking care not to damage the slap and the ridge,
The slot may be formed by cutting both sides by the same width.

As is well known in the art,
Ventilation around the gable roof wing is effective in drawing out the warm old air of the roofed space, usually the attic, to the outdoors. The wind that blows across the ventilation line is pushed up and above the ventilator by the roof's sloping surface, causing a lower pressure in the ventilator area, leading some attic air to the outdoors. To work.
When combined with a Sofitt ventilator, which introduces fresh air from the roof eaves, ridge ventilation typically provides more attic ventilation than other turbine ventilation or large ventilation ducts. However, the efficiency of this ventilator depends on the degree of convection of the outside air and the degree to which the wind crossing the ventilation line is not disturbed by the structure of the ventilator. The most effective ventilation would be open ventilation holes at all, but some cover is needed to prevent ingress of rainwater, dust and pests. Therefore, what should be considered when designing the cover plate is to construct an effective obstacle to prevent invasion of rainwater, dust and pests while maximizing suction by convection and wind, while maintaining aesthetics and durability. It can be manufactured at low cost and is easy to install.

The present invention meets the above design factors with a single mat 16 of variable mesh that is air permeable and is made of synthetic resin fibers arranged in a non-uniform array bonded with a phenol or latex binder and heat treated. To prepare. When subjected to a standard compression test of 1360 grams, the preferred embodiment of the present invention, a mat of only 5/8 inch thickness, exhibited 13% compression and 100% recovery. The tensile force was 55 PSI in the longitudinal direction and 64 PSI in the cross direction.

As used herein, the term "single" means that the mat member is made up of a single sheet, rather than being a stack or seam of different sheets.
This does not exclude strips of members spliced with roof gap fillers or other adhesive materials detailed below.

The mat 16 is preferably a continuous strip having a width of about 10-1 / 2 inch and a thickness of 5/8 inch. It extends laterally for the length of the slot and evenly overlies slot 12 and has a very low profile, so it has the same color as the rest of the roof, such as coronal shingles 18 in FIG. Almost unnoticeable when covered with homogeneous shingles or tiles.

The roofing boards 20 are spread in the usual manner, with the overlapping rows in order from the bottom row until reaching the slot 12. As shown in FIG. 1 and FIG. 2, the mat 16 is laid while unwinding from the wound end, centering the ends on the slot 12 and unwinding toward the other end of the slot. Go and cut from the roll at the other end. Coronal shingles 18 are placed on the mat 16 such that their edges overlap the front shingles while starting from one end and laying on the other, and the roof nails 22 are fitted with coronal shingles from above. 18, mat 16,
The roof plate (20) is inserted, and the bottom plate (14) and the slack (15) are driven in and fixed.

Since the mat 16 withstands sufficient compressive force, an operator presses the shingles 18 hard against the mat, and even if the nails 22 are driven so that only the nail heads come out above the plates, the coronal shingles 18
Is raised just 5/8 inch above the lower roof panel. When observed from the ground and distant places around the building, it is almost unnoticeable that it is raised 5/8 inch from this roof surface. Furthermore, the low profile of the ventilator is a substantial impediment to the wind that draws the attic air through the vent by blowing it across the ridge and reducing the pressure around the vent outlet. Don't

The mat 16 is attached by a simple method in which a predetermined length is cut out from the wound mat, the mat 16 is covered over the slot of the ridge, and the coronal shingles or tiles are nailed on it. be able to. If it is necessary, and desirable, to connect the strips of this mat member together, as shown in FIG. 3, abut the ends of the strips and attach it to the asphalt shingles or around the flushing. The joint can be easily created by covering the abutting portion with a synthetic resin rubber sealant used for sealing or other suitable filler or adhesive.

In the case of conventional asphalt or wooden crown shingles as described above, the mat exhibits sufficient compression resistance, but in another embodiment of the mat the roof is heavy terracotta. Alternatively, when covered with slate tiles, it is desirable to use the same material for the coronal plate of the ventilation part, but it is unavoidable that cracks will occur when attempting to strike a nail. As a result, these tiles are mounted on the mat by applying an adhesive rather than a nail through them. The mat is fixed in place on the roof with nails or glue before the tiles are mounted on the mat.

The weight of the roof tile and the permeation of the adhesive when adhering it to the mat make the mat excessively smooth from the normal state, and the mat portion is filled, so that the air flow in the mat is doubled. Make it worse. Therefore, there is shown an embodiment in which the solid core bodies 28 as shown in FIGS. 4 and 5 are arranged in a lattice pattern and this measure is taken.

The core is formed by pouring and solidifying a drip of liquid polyester, here nylon, into a fiber mat. A set of multiple reciprocating injection nozzles spaced approximately 3 inches apart after the basic 5/8 inch thick material has been cut to the appropriate width (12 to 16 inches for maximum width tiles). Pass under. As the mat passes, a thin-nozzle nozzle drops onto the mat, pouring molten nylon material until it reaches the structure that supports it from the web of moving mat, after which the nozzles rise upwards. Be lifted. The liquefied nylon solidifies immediately upon contact with air and sticks to the web material. In this way, FIG.
As shown in FIG.
Rows are formed.

For example, considering the use of a nozzle type, a typical core has a diameter of only 1/2 inch.
The time required for the reciprocating movement of the nozzle is determined by the degree to which the mat is advanced so as to draw a grid pattern on the mat at intervals of about 3 inches as shown in FIG. The spacing of this grid is
This mat material can be rolled and transported while having sufficient load resistance to prevent overcompression of the mat.
It is placed on the roof and can be cut to length.

The second embodiment described above is suitable for use with normal nailing shingles when heavy snow accumulates on the roof's corrugated shingles in the polar regions and abnormal and long-term pressure is applied to the roof. . Since the cores are regularly spaced and well dispersed, it is easy to avoid nailing through the core.

Furthermore, as shown in FIG. 4, the mat member is provided with two lateral edge strips 24 coated with adhesive material, each strip being approximately 1 inch wide. Deploy along the edge of one of its wider sides by the length. This strip 24 is covered by a tear-off protective strip 26 made of paper or other airtight material, until the mat is actually used,
It retains its tackiness so that it does not stick to the mats that are involved. Therefore, the installer puts the mat on the ventilation slot with the strip 24 on the lower side, peels off the protective strip 26, presses the rear mat against the roof shingles, and attaches the adhesive surface of the edge of the mat. To be adhered to both sides of the roof slot. Tile or corrugated shingles are mounted on the mat to provide a firm bond to the roof of the mat.

The mat 16 is formed from a non-woven fabric of a mesh of synthetic fibers of the type otherwise used as cleaning and polishing tools. Synthetic fibers (usually nylon or polyester) are unraveled, mixed, and then web-formed by a jet of air in a non-uniform manner by a synthetic machine commonly known as "Land Weber". This coarse fibrous web is sprayed with a water based phenolic and latex binder.
Sintered in a furnace, the fibers are bonded together to form a relatively hard mat with portions of appropriately sized pores between the irregular fibers. An example of this type of mat is the M29 polyester cleaning pad from "Lauren" Manufacturing Department of "Atchem North America". The preferred embodiment for mat 16 is the same as M29 described above, except that aluminum oxide is used in place of another, more expensive abrasive for use as a cleaning pad in the bond. And the resulting web is 5/8 inch deep and 10
-1/2 inch wide, 20 or 50 feet long. The specifications are as follows.
