Abstract

<P>PROBLEM TO BE SOLVED: To provide a ridge type heat insulator used between structural materials of a detached house or the like which has excellent fittability and which improves heat insulation and airtightness. <P>SOLUTION: A bent 1e of the ridge type heat insulator 1 comprised of a ridged shape and a trapezoidal ridged shape comprises a leg-closing groove 30a at the extending time, a leg-opening groove 30b at the extending time, and an extending connection 1f. When the ridged shape is made a flat shape at the time of engagement insertion, the leg-closing and leg-opening grooves 30a, 30b mutually open and close legs, and the width of the heat insulator is expanded about the extending connection 1f. Thus, even when the width of the heat insulator is made smaller than or equal to the dimension between the structural materials, the inhibition and flatness of the heat insulation clearance are secured, and the execution efficiency is improved. Then a compressed elastic concave channel 3a is provided in the long side direction, in the short side direction, and in the diagonal direction, and a convexity 1k for height adjustment and a concavity are provided on the undersurface of the heat insulator. Thus, compression elasticity in multiple directions is added. Furthermore, a finishing material is arranged and provided by temporarily mounting the heat insulator of varying thicknesses among the structural materials of varying cross-sectional dimensions by flush bearing equipment fixed and engaged on the undersurface of the structural materials. Thus, a heat insulation structure can be obtained which has excellent heat insulation/airtightness and execution efficiency. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a plate-like heat insulating material used for a heat insulating structure such as a floor, a wall, and a roof in a building, in particular, a wooden structure or a steel frame structure. Insert or insert in the short side direction all or part of the cross-sectional structure in the short side direction of the plate-like heat insulating material to be inserted and supported on the upper surface side between the structural materials consisting of columns and pillars etc. Yamagata that imparts, improves, stretchability, compressibility, compressibility, expandability, elasticity deterioration prevention, and shape retention, as well as shrinkage compression and height adjustment in the long side direction and diagonal direction It relates to a plate-like heat insulating material. Furthermore, these chevron-shaped plate-like heat insulating materials and flat plate-like heat insulating materials that have been widely used in the past (hereinafter, these chevron-shaped plate-like heat insulating materials and plate-like heat insulating materials may be simply referred to as plate-like heat insulating materials or heat insulating materials. )) Is fitted to and supported by the upper surface between the structural members substantially flush with the heat insulating structure insertion method using a flat support member, a support pin and a support bar.

  The heat insulation structure provided on the indoor side and the outdoor side in buildings such as detached houses is a structural material formed by large pulls, studs, joists, trunk edges, rafters, etc. used for floors, walls, ceilings, roofs, etc. It is constructed by inserting a hard plate-like heat insulating material such as polystyrene-based foamed resin between them, placing a floor board, wall board, ceiling material, field board, etc. as a base material on the surface and putting it on the crown. . Ordinarily, a large drawing, a stud, a pillar, a main building, etc. that form the framework of a house are called structural materials, and joists, trunk edges, rafters, etc. are called structural base materials. These large draws, studs, pillars, joists, trunk edges, rafters, etc., which are the objects to be inserted, are collectively referred to as structural materials, and the insertion space of the heat insulating material formed by these structural materials being parallel and side-by-side. It shall be called between structural materials.

  In addition, surface materials such as structural veneers, plaster boards, and field boards provided as a foundation layer for floor boards, wall boards, roofs, and the like are usually referred to as foundation materials. A generic term for these base materials covering the upper surface side of the inserted heat insulating material is called a finishing material. In addition, it expresses the direction between the plate-like heat insulating material, the structural material, and the structural material, and the name of the lower surface means that the construction surface such as a floor, a wall, or a roof on which the heat insulating material is inserted may be a horizontal surface, a vertical surface, an inclined surface, etc. The side viewed from the direction in which the heat insulating material is inserted between the structural materials is referred to as the upper surface or the upper surface side between the plate-shaped heat insulating material, the structural material, or the structural material, and the back surface side is referred to as the lower surface or the lower surface side. The length direction of the rectangular plate-shaped heat insulating material is referred to as a long side direction (or long side), and the width direction is referred to as a short side direction (or short side or width direction).

  Usually, the plate-shaped heat insulating material to be inserted between the structural materials is a plate-shaped or mountain-shaped in-mold molded product in which a compression ditch or the like parallel to the long side direction of the heat insulating material having a predetermined outer dimension is previously formed. In addition, a plate-like product obtained by cutting an extrusion molded product or an in-mold block molded product into an insertion dimension is used. What is important in the heat insulation structure using these plate-shaped heat insulating materials is the insertion gap between the heat insulating material and the structural material such as the large pull, the stud, and the joist, and the connection gap between the heat insulating materials continuously laid. In addition, in order to prevent the thermal insulation material from slipping off from the upper surface between the structural materials with dimensions larger than the thermal insulation material thickness, over-pressing, or tilting, both upper surfaces are fitted and held so that they are substantially flush. It is to be supported and to arrange a finishing material on the surface to eliminate the gap space.

  For this reason, for example, in Patent Document 1 and Patent Document 2 and the like, it is possible to attach a metal fitting in advance to a structural material such as joists and place a plate-like heat insulating material on the metal fitting protruding from the structural material. Are listed. Further, a method is disclosed in which a mounting bracket is inserted and fixed in advance on a side surface of a plate-like heat insulating material and then disposed on a structural material (see Patent Document 3).

  Moreover, in patent document 4 etc., as another method of adjusting the height of the heat insulating material for joists, a method of providing a support piece having elastic flexibility below the large pull is described. A method for supporting the heat insulating material by projecting both sides of the metal fitting to the position of the thickness of the heat insulating material at the bottom of the joists is disclosed.

  Further, as another method, Patent Document 6 and the like describe a ditch groove that is parallel to the long side surface of the plate-like heat insulating material (hereinafter, also referred to as an elastic ditch or a slit) as an upper surface, a lower surface, Or, it is formed on both sides and gives compression elastic force exceeding the plasticity of the heat insulating material in the short side direction of the plate-like heat insulating material, and compression-inserted to hold and fix the side surface of the structural material and the heat insulating material with elastic repulsive force Proposed.

  In addition, as another method for improving the insertion property, Patent Document 7 and Patent Document 8 describe in advance that the cross section in the short side direction to be inserted between the structural materials has a substantially trapezoidal mountain shape, and inclined band portions on both sides. The lower edge width dimension of the end face is smaller than the insertion width dimension between the structural members, and the angled bent part is provided with a bent groove, and the angled part is pushed in and expanded to flatten it to be flat. An angle plate-like heat insulating material has been proposed.

Furthermore, the present inventors have adjusted the dimensions of the plate-like heat insulating material in the multi-surface direction by providing elastic concave grooves that are not parallel to the long-side direction and short-side direction of the plate-like heat insulating material and diagonally or meandering. In addition, a plate-like heat insulating material that is excellent in insertion property and improves heat-insulating airtightness by enabling compression elasticity is proposed. (See Patent Document 8)

  In the configurations of Patent Document 1 and Patent Document 2 described above, the receiving metal fitting is a dedicated metal fitting for supporting a flat heat insulating material having a specific thickness, and is shared with different heat insulating material thicknesses and cross-sectional dimensions of the structural material. This is impossible, and the metal fittings are fixed to the upper surface of the structural material and sandwiched between floor materials, and the cause of floor noise has been pointed out. In addition, it is a two-step process of mounting the metal fittings on the structural material after construction at regular intervals, and then placing the heat insulating material. The sheath fixing force is weak, and it is easy to come off or drop off due to the impact when inserting the heat insulating material. Further, in the method of Patent Document 3, the metal fitting is inserted in advance at an appropriate position on the side surface of each plate-like heat insulating material at the site, and inserted as a heat insulating material with ears, but the work is complicated, and there are mounting errors and inclinations. It is easy to come out, and it is easy to come off the receiving bracket, and a dedicated bracket is required for each thickness. It is easy to drop off on the vertical surface of the column, etc., and it is easy to come off due to impact when a heavy object such as a large heat insulator is fitted.

    Further, Patent Document 4 shows a structure in which a heat-insulating material is supported by sandwiching an elastic dish-shaped metal fitting between a joist and a large pulling material. However, the structure cannot be sandwiched by a large pulling or a column part. Moreover, although patent document 5 clamps a receiving metal fitting between a joist and a large pull, it is a fixed height and a special receiving metal fitting is needed each time. These metal fittings must be mounted on the large pulling material of the lower member of the joists, and the amount of the metal fittings used is enormous, resulting in problems of cost and construction work.

  Furthermore, in the method disclosed in Patent Document 6 and the like, a plurality of concave grooves parallel to the long side surface of the plate-like heat insulating material are provided on the upper and lower surfaces, and compression elasticity in the width direction of the plate-like heat insulating material is provided. It is a structure that makes it easy to fit between materials, and holds and fixes between structural materials and prevents gaps. These concave grooves are usually at a depth of approximately ½ or more of the thickness of the plate-like heat insulating material on both the upper and lower surfaces, and open in the end face by longitudinally cutting in the long side direction. For this reason, the effect of compression elasticity is only in the width direction, it is impossible to cope with the long side direction and the diagonal direction, etc., it cannot cope with the construction accuracy of the structural material, twist, warp, etc., and the neck bends along the elastic concave groove It is easy to warp and meander in the upper and lower surfaces, and the form retention is unstable, and the entire width is compressed and inserted during insertion, so that it becomes difficult to be horizontal or flush.

  In addition, since the elastic stress after insertion is concentrated on the connecting flesh at the bottom of the deep groove, the elastic stress tends to deteriorate in a short period of time, the groove width becomes narrow, the elastic holding force between the structural members decreases, and vibration occurs. In addition, there is a drawback that it easily slips off from the surface of the structural material over time and generates a gap with the finishing material.

  Moreover, in patent documents 7 and 8, it replaces with a plate-shaped and simple rectangular plate-shaped heat insulating material, the central band part of the upper surface of a short side direction makes flat shape, and the both sides are slanted about 5-20 degrees. It is a roughly trapezoidal chevron shaped plate-shaped heat insulating material consisting of an inclined band with the same thickness as the central band inclined downward, and the lower edge width dimension of both outer end faces of the inclined band in the short side direction is smaller than between structural materials The lower edge is pre-inserted as a dimension, and the chevron is pushed in between the structural members and inserted into a flat plate shape, but the bent part consisting of 2 is a bent groove that opens only on the upper surface side and a connecting meat part on the lower surface Due to the formed structure, when the plate is expanded into a flat plate shape, the flexibility of the connecting meat part is inferior, excessive bending elastic stress is generated, only the lower surface side is expanded in the width direction, and the upper surface side is compressed. Will be.

  Therefore, concentrated stress acts on the lower edge of both end surfaces of the pre-inserted heat insulating material and the corner of the structural material, and the corner bites into the heat insulating material and obstructs the insertion, but it is forced to push in too much, It is a cause of unevenness. Moreover, even if it expands in flat form, a mountain-shaped formation part is returned reversibly with an excessive bending elastic stress. To solve this problem, the upper edge width of both end faces should be reduced to the same size as the structural material, but after insertion, the upper edge width is reduced by the closed groove of the bending groove, A gap is formed between the structural materials, and the insulation material falls off and slips off. In particular, this tendency becomes remarkable in the central portion in the long side direction where there is no support portion such as a large pulling material under the joists. Also, on the lower surface side of these heat insulating materials, there is a height adjustment convex part that makes the structural material such as joists and the heat insulating material flush with each other, but distortion exceeding the compressive elastic modulus occurs, and the height adjustment over time The convex portion is reduced to form a gap.

  Furthermore, in recent years, structural materials such as joists have been omitted, or due to the widespread use of outer and inner heat insulating houses, large-sized plate-like heat insulating materials have been directly used between large-sized structural materials such as large pulling materials, wall columns, and rafters. The specifications for insertion and placement are widespread. However, the space dimensions of the large draw, the stud, etc. are larger than the space dimensions between the joists, and the width of the heat insulating material inserted between the joists is about 250 mm to 450 mm. × Large 1820 mm × Thickness 35 to 100 mm In addition, the large pulling material is a square material of 90 mm to 105 mm, but it cannot be generally stated, but the thickness of the heat insulating material is often about 25 mm to 60 mm, and an unevenness and a gap are generated due to excessive push-in or falling off by its own weight. . It is difficult to fit such a large flat plate-shaped heat insulating material on the floor surface or wall surface without any gap between the upper surface of the structural material and the conventional heat insulating material from the viewpoint of construction workability, construction structure surface, and the like.

  In addition, the plate-like heat insulating material used for roof insulation is ventilated and drained by providing a ventilation recess on the upper surface of the plate-like heat insulating material to be inserted between the rafters on the main roof and providing a ventilation layer between the lower surface of the base plate. In addition, the heat insulation structured flat plate heat insulating material with functions such as piping is adopted, but the problem of ensuring insertion workability, flushness, gap suppression of these functional heat insulating materials such as ventilation is This is the same as the plate-shaped heat insulating material described above.

  As mentioned above, improvement of heat insulation, airtightness, and improvement of heat insulation workability are still very satisfactory despite being extremely important issues from the viewpoint of comfortable living and energy saving of detached houses. There is no current situation. Under such circumstances, the invention disclosed in Patent Document 9 by the present inventors has been proposed in order to solve and improve the conventional drawbacks, but the present invention further improves its performance. In addition, the invention is a useful invention in which the problems of heat insulation performance and heat insulation workability possessed by the plate-like heat insulating material are widely improved.

The present invention relates to a method for inserting and inserting a plate-shaped heat insulating material using the flat surface support for a plate-shaped heat insulating material according to any one of claims 11 to 16.

  Furthermore, the present invention provides 19) pre-cut hole processing and pre-cut slit processing in advance on the side surface position of the structural material that supports the plate-like heat insulating material between the structural materials substantially flush with each other. The present invention relates to a heat insulating structure for a plate-shaped heat insulating material, wherein a support piece is mounted and the plate-shaped heat insulating material is fitted between the structural materials.

  Further, the present invention relates to 19) a locking projection for locking the height adjustment convex portion on the lower surface of the plate-like heat insulating material at the side surface position of the structural material for supporting the plate-like heat insulating material substantially flush between the structural materials. It is related with the heat insulation structure of the plate-shaped heat insulating material characterized by mounting | wearing with the support bar made from a foaming synthetic resin provided, and inserting and inserting a plate-shaped heat insulating material.

  According to the present invention, a mountain shape in which an inclined band portion is connected to a first bent portion that forms a mountain-shaped portion with the substantially central portion of the plate-shaped heat insulating material as a top portion, or a substantially central portion is a flat central band portion. A chevron plate-like heat insulating material in which a chevron-shaped forming part is provided in a trapezoidal shape in which an inclined band part is connected to a first bent part as a top part, and a second bent part is connected to both side ends and one side end of the chevron-forming part. By adopting a chevron plate-shaped heat insulating material provided with lateral flat portions, it becomes possible to make the width of the chevron-shaped heat insulating material equal to or less than the insertion width between structural materials. The width of the heat insulating material is expanded, and gap suppression and surface uniformity can be ensured.

Furthermore, one or more extension closed leg grooves and / or extension leg grooves are provided on the upper surface and / or the lower surface of the heat insulating material on the first bent portion and the second bent portion, and a) the upper and lower surfaces face each other. Open at a position, b) Open at another position where the upper and lower surfaces do not oppose, or c) Open at an opposite position on the upper and lower surfaces and another position where they do not oppose Therefore, the bending elastic stress generated in the first and second bent parts when the angle forming part is extended into a flat plate shape is dispersed and offset by opening and closing the closed leg groove when extended and the open leg groove when extended. It can be relaxed, and the flexibility and expandability of the extension connecting parts of the first and second bent parts are increased, and the angle forming part can be easily extended and inserted into a flat plate shape with a slight force. The width of the heat insulating material can be expanded by making the mountain shape into a flat plate shape with the axis as the axis.

  Thus, the gap suppression and flushness of the heat insulating material inserted between the structural materials are ensured, and it is possible to prevent the heat insulating material from slipping downward from between the structural materials due to the compressive elastic stress at the time of expansion. The gap with the finishing material is also suppressed. The effect of these inventions is that the heat insulating material width is equal to or less than the insertion width dimension between the structural materials, so that the preliminary insertion is performed between the structural materials, and the expansion and insertion is performed with a slight force. If the finishing material is disposed in the inserted state, it can be expanded, inserted, and expanded by the pressing force. For this reason, it is not necessary to pre-compress and insert the width of the conventional flat plate-like insulating material into the dimensions between the structural materials in advance, and forcibly insert it while pre-inserting the lower end surface of the trapezoidal chevron plate-like insulating material. Thus, the problem of non-uniformity that occurs is also eliminated.

  Also, the force to reversibly return to the chevron shape due to the reaction force of the bending elastic stress at the time of extension and insertion into the flat plate shape is alleviated by opening and closing the leg when the extension is closed and the extension leg when opening and closing. It is suppressed. In addition, the extension connecting part formed on the bottom leg part of the first and second bent parts at the time of extension and at the time of extension of the leg leg is at the angle of the inclined band part, at the time of extension and at the time of extension. Depending on the structural form examples (FIGS. 1 to 8) of the various extended connecting portions formed by each of the open leg grooves alone or by constricting each other, the desired structure, thickness, and expansion width are It can be selected, and the degree of bending elastic stress at the time of extension and insertion can be set, and the form retainability such as prevention of neck bending of the bent portion can also be set.

  Further, Patent Document 6 and the like artificially compress and insert the heat insulating material width larger than the dimension between structural materials, or Patent Documents 7 and 8 have a lower edge width dimension of both end faces smaller than the dimension between structural materials. In the present invention, for example, the width of the heat insulating material is structured against the problem that the corner portion of the heat insulating material bites into the end surface of the heat insulating material due to excessive bending elastic stress generated during extension while pre-inserted. If the flexibility of the bent part is improved to be equal to or less than the inter-material dimension, pre-inserted and expanded and inserted into a flat plate shape, the width of the heat insulating material is expanded, and the gap between the structural materials is suppressed and the structural material Since the elastic holding force is ensured, the problem of unevenness and incompatibility due to compression insertion or excessive pressing of the heat insulating material is solved, and the insertion workability and heat insulation are improved. For example, in the case of heat insulation for joists, if a floorboard is placed on a large pulling material in a mountain shape, the chevron forming part is expanded and expanded by the weight of the floorboard, and the gap is closed and leveled. Thus, the insertion work is simplified, and high heat insulation can be secured.

  In addition, structural materials are constructed with materials of various cross-sectional dimensions from the viewpoint of the structure, strength, cost, etc. of houses, and plate-like heat insulating materials have various heat insulating material thicknesses depending on the region and energy saving standards. There are a wide variety of combinations, and each time it is difficult to adopt an optimal specific heat insulation construction method, it is important to apply common materials and common construction methods. For example, in large thermal insulation, various materials such as 90 mm square material, 105 mm square material, 120 mm square material and the like are used as appropriate, and the thermal insulation material thickness is also 20 mm to 100 mm. Various combinations of these are implemented, but in the present invention, even with various combinations of different heat insulating material thicknesses and cross-sectional dimensions of the structural material, the fastening and locking portions and the elastic bearings are formed from the lower surface side of the structural material. It is possible to share a flat support member (shown in FIGS. 11 to 15) of a plate-like heat insulating material made up of an arm part and a support part, etc., ensuring heat insulation and improving workability.

  In addition, the widths of these fastening and locking portions can be made common, can be expanded and contracted, can be held and clamped from the lower surface side of the structural material, and the locking nail portion and the reverse nail portion can be integrated as appropriate. The installation also eliminates the hassle of separately prepared nailing work, making it possible to attach flush supports before and after the construction of structural materials such as large pulling materials, and can be divided in two By adopting a structure, it is possible to attach to a base tree or the like which is a one-side support.

  Further, the advantage of the surface-equipped support of the present invention is that it is not necessary to artificially fit and insert a conventional heat-insulating material on the surface of the surface-supporting device, which is fixed and fixed between structural members. Temporarily placing the material and placing the finishing material such as flooring and covering it, the top surface of the heat insulating material and the structural material and the bottom surface of the finishing material can be substantially flush, ensuring heat insulation and workability The results can be greatly improved in simplification and reduction of construction man-hours.

  In addition, when pre-cutting structural materials, the mounting holes and mounting grooves of bearing pins and bearing pieces, which are flush bearings, are simultaneously processed, and the insulation pins are placed and placed at the construction site. The goal is achieved just by letting it do. Also, it is made of foamed synthetic resin, and it is engaged with the lower surface side projection on the heat insulating material side to provide a convex portion, or in the case of a heat insulating material having a different thickness, the convex portion is compressed and the height can be adjusted. It is possible to make a flat surface by attaching it to the side surface of the structural material. (Shown in FIGS. 16 and 17)

  Further, on the lower surface side of the plate-shaped heat insulating material of the present invention, there are provided a height adjusting convex portion protruding below the thickness of the heat insulating material and a strain absorbing concave portion for reducing the compressive strain rate of the height adjusting convex portion. Therefore, the conventional height adjustment convex part has an excessive permanent distortion rate, shrinkage degradation with time in the height direction, and the problem of forming a gap with the finishing material is solved. The height can be maintained.

  Also, the depth of the elastic groove having a depth of approximately 1/2 or more of the thickness of the heat insulating material formed on the plate-like heat insulating material along the long side direction on the lower surface side is set at both end portions of the groove. By making the central part of the long side shallower or deeper, the compressive elastic force of the concave groove can be increased / decreased and set along the long side direction, so that it is possible to ensure uniformity during insertion and to eliminate the lapse of time And elastic deterioration can be suppressed.

  In addition, the chevron plate-shaped heat insulating material having a large size for large pulling or for walls, etc. improves the insertion property and airtightness, but is bulky and difficult to carry in compared with the conventional flat plate-shaped heat insulating material. The first bent portion is provided with a cut groove which is a closed leg groove when extended on the upper surface, and the second bent portion is provided with a cut groove which is a closed leg groove when extended with the lower surface. A strip-shaped reinforcing material is affixed to the opposite side of the opposite surface, and is transported to the construction site as a flat plate-shaped heat insulating material. The bent portion is bent at the time of insertion and expanded as a mountain-shaped plate-shaped heat insulating material. If it is inserted and expanded, the problems such as the insertability of large heat insulating material, gap suppression, and material handling are solved at the same time. (Shown in FIG. 7)

  The chevron plate-like heat insulating material referred to in the present invention is configured in advance so that a part or all of the cross-sectional structure in the short side direction of the plate-like heat insulating material is formed by the chevron forming part, and at the time of insertion between the structural materials, the chevron forming part Is expanded and expanded in a flat plate shape so that the upper surface of the structural material and the upper surface of the heat insulating material are fitted to be substantially flush with each other, and the insertion gap between the structural material and the heat insulating material is suppressed and the structural material is compressed by the compressive elastic stress of the heat insulating material. It refers to a chevron plate-shaped heat insulating material intended to hold the heat insulating material between them for a long time.

  The bent portions referred to as the first bent portion and the second bent portion in the present invention are the extended leg closed groove and the extended leg open groove formed in the bent part, and the opened leg closed leg and the closed leg groove. It is comprised with the expansion connection part which consists of the meat | frame connection part of the heat insulating material except opening depth. These first and second bent parts are connected to and connected to the apex and inclined band part of the mountain-shaped forming part, the inclined band part and the lateral flat part at the extension connecting part, and the angle plate-like heat insulating material is extended into a flat plate shape. When inserting, the closed leg groove at the time of extension and the open leg groove at the time of extension are opened and closed to expand the hinge function and heat insulating material width to make the mountain shape flat, and these are various structural forms In accordance with the change, it refers to a portion having a form-retaining property that prevents breakage separation and neck breakage of the heat insulating material at the extended connecting portion (bent portion).

  The extension closed leg groove formed in the first and second bent portions refers to a concave groove that opens in the upper and lower surfaces and closes the open leg groove when the mountain forming portion is extended in a flat plate shape. The extended leg-opening groove refers to a concave groove that opens to the upper and lower surfaces and opens the substantially closed leg-like groove when the mountain-shaped portion is extended in a flat plate shape. These extended leg closed grooves and extended closed leg grooves are formed by the first and second bent portions, either alone or by facing each other, but depending on the purpose of forming these plate-like heat insulating materials, It is desirable that each opening depth, opening width, etc. be selected in any desired shape.

  Stretching and insertion refers to spreading the chevron forming portion into a flat plate shape, and insertion refers to mounting and loading a heat insulating material between structural materials. The term “expanded” means that the chevron plate-shaped heat insulating material is expanded into a flat plate shape, and the heat insulating material width dimension at the time of forming the chevron is expanded and increased. Usually, in the chevron plate-shaped heat insulating material of the present invention, for example, when pre-inserting between structural materials to form a mountain shape into a flat plate shape, expansion, insertion, and expansion are performed as a series of behaviors. Therefore, there is no need to separate them clearly.

  Pre-compression means that the heat insulating material width larger than that between the structural materials is artificially pressed and contracted. Preliminary insertion means that all or part of the width dimension of the heat insulating material (lower end portion) is set to be approximately equal to or less than the insertion width dimension between the structural materials and is inserted between the structural materials without being pre-compressed. In addition, even if the insulation material width is equal to or greater than the dimension between structural materials, it is also used to supplement the pre-insertion insertion along the inclination without providing pre-compression by providing an inclined portion for insertion at the lower end of the end face Just do it.

Examples of the foamed synthetic resin used in the chevron plate-shaped heat insulating material of the present invention include foamed polystyrene resin, foamed polypropylene resin, foamed polyurethane resin, foamed vinyl chloride resin, and foamed polyethylene resin. In terms of heat insulation, water resistance and buffering properties, in-mold molded polystyrene foam or extruded polystyrene foam is preferred, and the foaming ratio is preferably about 25 to 100 times. As a means for forming the heat insulating material, there are mainly a method by in-mold molding of a bead method and a method of cutting and forming an extruded product.

  Although the size of the heat insulating material of the present invention cannot be generally described, for example, in the case of a material to be inserted between joists, the width is about 250 mm to 600 mm, the length is about 600 mm to 1200 mm, and the thickness is In general, a thickness of a heat insulating material defined for each region is applied, but a thickness of about 20 mm to 100 mm is generally used. In addition, in the case of a large-sized heat insulating material that is inserted between a large pull or a stud, the width is about 600 mm to about 910 mm, the length is about 900 mm to about 1800 mm, and the thickness varies depending on the region. The thing of about 20 mm-100 mm is common. From the structural dimensions of these heat insulation construction sites, etc., the construction of inclined bands and side flat parts that are connected at the inclination angle and bent part of a single mountain shape and trapezoidal mountain shape centering on ensuring the workability, heat insulation and air tightness, etc. It is desirable to select.

  The inclination angle for forming a single mountain shape or a trapezoidal mountain shape is preferably about 5 to 15 degrees from the viewpoint of formability, material handling properties, stretchability, fitability, and securing of expanded dimensions. In addition, the right and left inclination angles of the inclined band portion are preferably equal, but are not limited. For example, along the long side direction, one side is a side flat portion and the other one side is an inclined heat insulating portion. The insertability of the material can be improved by appropriately changing the left and right inclination angles. In addition, in the case of a small width heat insulating material such as a joist heat insulating material, it is desirable to form a mountain-shaped forming portion at a substantially central portion in the short side direction, but in a wide heat insulating material such as a large pulling heat insulating material. It is desirable to form them by shifting to a position that is easier to extend closer to one side than the central portion, from the viewpoint of expansion and insertion workability.

  Moreover, it is preferable that the chevron plate-like heat insulating material formed with the entire cross-sectional structure in the short side direction in a single mountain shape or a trapezoidal mountain shape is applied to a heat insulating material with a small width such as a heat insulating material for joists. In addition, a chevron plate-shaped heat insulating material in which a part of the cross-sectional structure in the short side direction forms a chevron-shaped portion and a flat plate-like rectangular flat portion is provided on both sides or one side. It is desirable to apply to a small to wide heat insulating material because the effect of the above-described invention is exhibited.

  When the first bent portion and the second bent portion shown in FIG. 1 are formed so as to face each other on the upper and lower surfaces to form one extension closed leg groove and one extension open leg groove, The structure is such that the meat connecting portion formed between the groove bottoms is formed as an extended connecting portion, and the extended connecting portions are formed substantially at the center in the thickness direction of the heat insulating material with the respective opening groove depths being substantially equal. Is desirable. The expansion dimension of the heat insulating material width in this structure is the length connecting the mountain-shaped forming part and the side flat part to both end faces in the width direction with a straight line at the center line of the extended connecting part formed by bending, and the heat insulating material This is roughly equivalent to the difference between the outer width dimension at the time of the formation of the mountain shape, and the expanded width is the formation structure of the extension closing leg groove, extension extension leg groove, extension connecting part, and inclination of the inclined band part. It can be selected appropriately depending on the angle or the like.

  In addition, the formation position in the case of forming one extension closed leg groove and one extension open leg groove on the upper and lower surfaces of the one bent portion is in the thickness direction of the heat insulating material, Although it is desirable to face each other on the center line of the bent portion formed from the upper surface to the lower surface, for example, at the position sandwiching the center line, 1 extension leg closing groove and 1 extension Since the object is achieved by forming the opening and closing leg grooves within the bending elastic stress propagation range that can be closed and opened in conjunction with each other, there is no particular limitation.

  Further, another one bent portion forming the first bent portion or the second bent portion is, for example, shown on the first bent portion in FIG. When the extension leg leg groove is formed in such a manner that the extension leg leg groove is sandwiched from below and the extension leg leg groove is formed on the lower surface, the extension leg closing groove and the extension leg extension groove The opening depth is not particularly limited, and the heat connecting portion of the heat insulating material excluding the respective opening depths forms the stretch connecting portion, so that the desired flexibility and stretchability of the stretch connecting portion are ensured. However, from the heat-insulating surface, the extension leg that opens to the lower side should be shallow, and the extension leg that closes the leg should be deep. It is desirable to do. Further, the extended leg closing groove that closes on the upper surface side may be deep, and the extended leg opening groove that opens on the upper surface side is desirably shallow.

  Also, from the structure in which, for example, one of the first bent portion and the second bent portion is formed by the extension connecting portion with the extension closed leg groove shown in the first bent portion in FIG. It is desirable from the viewpoint of form retention after extension that the opening angle of the extension leg groove such as the extension closing leg groove is generally equal to or less than the inclination angle forming the mountain shape, and the opening depth is Further, 1/2 or more of the thickness of the heat insulating material, more preferably 2/3 or more is desirable, and the meat connecting portion of the heat insulating material excluding the opening depth forms the stretched connection portion. Depending on the outer dimensions of the heat insulating material, it may be selected as appropriate from the construction flexibility, extension, and insertion, and the end of the closed leg groove may be V-shaped when extended, and it will be easy to close the leg during extension by making it arc shape So desirable.

  Further, for example, one of the first bent portion and the second bent portion is constituted by the extended leg opening groove and the extended connecting portion shown in the first bent portion of FIG. When opening the legs after extension, the opening width of the extension leg grooves, such as the opening leg grooves when extended, should be the minimum width that can be formed by molding, nichrome wire, saw blade processing, etc. The opening depth is desirably 1/2 or less of the thickness of the heat insulating material, and more desirably 2/3 or more.

  The opening width of the above-mentioned various opening leg grooves at the time of extension is preferably formed with a minimum width that can form a groove when forming a mountain-shaped plate-like heat insulating material from the aspect of ensuring heat insulation after the leg opening. For internal molding, 1 mm or less is desirable, and for nichrome wire processing or saw blade processing, 1.5 mm or less is desirable. The tip of the leg opening groove at the time of extension may be V-shaped or rectangular, and it is desirable to make it arc-shaped because the leg can be easily opened at the time of extension.

  Further, when a height adjustment convex portion protruding downward from the thickness of the heat insulating material and a strain absorption concave portion for reducing the compression strain rate of the height adjustment convex portion are provided, for example, the height of the joist material: In the case of 40 to 45 mm and heat insulating material thickness: 30 to 40 mm, it is desirable that the total heat insulating material thickness = heat insulating material thickness + height adjusting convex height = the maximum height of joist 45 mm. The relationship between the convex part and the concave part is, for example, when the insulating material thickness is 30 mm and the convex part height is 15 mm and the concave part depth is 10 mm, the compressive strain rate = 5 ÷ (15 mm + 10 mm) × 100 = 20%, Insulation thickness: 40 mm, convex height 5 mm, concave 10 mm compression strain rate = 5 ÷ (5 mm + 15 mm) × 100 = 20%. If the thermal stress of this thermal strain is supported by the elastic stress of this compressive strain rate Well, compressive strain rate is 30% or less More desirably not be compression set by its own weight over time adiabatic material when 20% or less is increased, it is the flush is maintained.

  The flat surface support of the present invention (shown in FIGS. 11 to 15) is the heaviest heat insulating material to which the elastic repulsion force of the elastic support arm portion according to the number of surface single support members provided for each heat insulating material is applied. 2 times or more of its own weight, more preferably 3 times or more, and based on the fact that the surface resilience is maintained by maintaining the elastic repulsive force over a long period of time, the elastic repulsive force and It is only necessary that the engagement locking strength is appropriately designed. In general, in the case of a large pulling heat insulating material, the object can be achieved if at least four or more supporting portions (one surface supporting device) are secured for one heat insulating material.

  The material of the flat support is metal plate (thin steel plate, brass plate, etc.) pressed products, plastic injection molded products such as polypropylene, extruded products cut products, and metal wires (iron wire or brass wire) bent products In addition, a composite processed product combining these may be used, and the shape is not particularly limited. The bearing pins and bearing pieces are preferably made of metal or synthetic resin from the viewpoint of cost, etc., and the supporting bars are preferably molded products such as foamed polystyrene resin and foamed polypropylene resin or nichrome wire cut parts from the viewpoint of cost and performance. .

  In addition to the effect of the chevron plate-like heat insulating material of the present invention, the present inventors have previously proposed a structure of an elastic groove that opens on the lower surface side in the width direction, long side direction, diagonal direction, etc. of the heat insulating material. The slit structure described in Japanese Patent Application No. 2003-208771, which is the invention of the present invention (referred to as an elastic concave groove or concave groove in the present invention), is applied, and the discontinuous portion shown in FIG. And a structure in which the depths of both end surface portions and the central portion of the elastic concave groove along the long side direction shown in FIG. And suppression of elastic deterioration can be improved.

  The flat surface support of the present invention (shown in FIGS. 11 to 15) is the heaviest heat insulating material to which the elastic repulsion force of the elastic support arm portion according to the number of surface single support members provided for each heat insulating material is applied. 2 times or more of its own weight, more preferably 3 times or more, and based on the fact that the surface resilience is maintained by maintaining the elastic repulsive force over a long period of time, the elastic repulsive force and It is only necessary that the engagement locking strength is appropriately designed. In general, in the case of a large pulling heat insulating material, the object can be achieved if at least four or more supporting portions (one surface supporting device) are secured for one heat insulating material. The material of the surface support may be a pressed product of a metal plate (thin steel plate or brass plate), a plastic injection molded product or a cut product of an extruded product, or a bent product of a metal wire (iron wire or brass wire). These may be combined processed products, and the shape is not particularly limited.

Example 1
FIG. 1 shows an inclined band composed of an inclined angle theta which is connected to the both sides in the long side direction by bent portions 1e with the first bent portion 1e at the substantially central portion of the single plate-shaped heat insulating material 1 of the present invention as a top portion. It is the perspective view and sectional drawing which show the mountain-shaped plate-shaped heat insulating material 1 which provides the side flat part 1b connected with the part 1a and the 2nd bending part.

And an extended connecting portion 1f composed of a meat connecting portion E narrowed at the opening depth F, and provided on both sides with an inclined band portion 1a inclined downward, The second bent portion 2 is a meat connecting portion that is narrowed by one extending leg opening groove 30b that opens upward and one extension leg closing groove 30a that opens downward. A lateral flat portion 1b is provided that is connected to both sides thereof. The side flat portion 1b is provided with an elastic groove 3a provided with a discontinuous portion 2f parallel to the long side direction, and an inclined surface 1c for pre-insertion is formed below the end surface 1d of the side flat portion 1b. The bottom surface is provided with four height-adjusting protrusions 1k (for simplicity of illustration, the details will be described in FIG. 9) formed along the long side direction, and the structural material height P and the heat insulating material thickness are provided. The structure which enables the height adjustment of R is shown with the perspective view.

  (B) is a cross-sectional view in which the chevron forming portion is pre-inserted without extending the chevron forming portion, with the heat insulating material width B molded in-mold between the joists 51 arranged on the large pulling material 50. The correlation between the structural material dimension V and the heat insulating material 1 is indicated by A, where the maximum width dimension of the heat insulating material width when the heat insulating material 1 is pushed in, expanded, inserted and expanded. In other words, even if the heat insulating material width B is equal to or less than the dimension V between the structural materials, it is expanded and expanded at the time of insertion, so that the insertion gap is suppressed and the elastic holding force between the structural materials is secured. Further, even if the heat insulating material width B is equal to or larger than the structural material dimension V, the side flat portion 1b is compressed by the inclined surface 1c for pre-insertion and can be pre-inserted without difficulty. Corresponding to the size, the gap between the structural materials can be absorbed within the range of the width of the heat insulating material B during the molding in the mold and the size width of the expanded maximum dimension A, and even if the heat insulating material 1 is made common, Is suppressed.

  In (c), the flooring 60 is disposed on the heat insulating material 1 that is pre-inserted in the shape of a molded product, and the chevron forming portion of the heat insulating material 1 is pushed in, expanded, and expanded by its weight. FIG. 3 is a cross-sectional view in which a height adjustment convex portion 1k is compressed to adjust the height, and a heat-insulating structure with high airtightness is formed. The extended leg closing groove 30a opens at an angle substantially equal to the angle theta of the inclined band portion 1a, closes during extension, prevents reverse warping, and maintains a flat plate shape. The extended leg opening groove 30b is formed with a minimum width J that can be formed (a molded product is 1 mm or less), and at the time of extension, the leg is opened with an angle theta that is substantially the same as the formation angle theta of the inclined band portion 1a.

  The extended connecting portion 1f is extended and fitted to expand the heat insulating material width B, and the elastic compression force suppresses the gap between the structural materials and elastically holds them. The height adjustment protrusion 1k is compressed to the structural material height P and the height is adjusted. The extended connecting portion 1f is formed of a narrowed meat connecting portion formed by one extended leg groove 30b and one extended leg groove 30a formed opposite to each other, and a thickness R of the heat insulating material is formed. If it is formed on the approximate center line, it is desirable because the bending elastic stress is easily relieved and the flexibility is increased.

Example 2
FIG. 2 shows another embodiment in which the side flat portions 1b are provided on both sides or one side of the chevron forming portion of the single chevron plate-like heat insulating material 1. (A) is sectional drawing which pre-inserted the heat insulating material 1 which provided the side flat part 1b in the both sides of the mountain-shaped plate-shaped heat insulating material 1 between structural materials.

  The first bent portion 1e at the top of the mountain is formed by opposing one extending leg closing groove 30a opening on the upper surface side and two extending leg opening grooves 30b opening on the lower surface side. It consists of an extended connecting portion 1f consisting of a constricted meat connecting portion of a heat insulating material excluding the opening depths M and Q, and the other two second bent portions 1e are opened at the time of two extended openings opened on the upper surface side. The leg groove 30b and the one closed leg groove 30a opened on the lower surface side are formed so as to face each other, and from the extension connecting portion 1f formed of the meat connecting portion of the heat insulating material excluding these opening depths M and Q In the embodiment of the plate-like heat insulating material 1 in which elastic concave grooves 3a and 3b are formed on the upper and lower surfaces of the side flat portion 1b, and the thickness of the heat insulating material is the same as the height P of the joist 51. is there. For example, the spread leg groove 30b in this structure is shallow, the spread leg closing groove 30a is deep, and the two spread leg grooves 30b are formed opposite to the spread leg groove 30a. And, since the total opening cross-sectional area of the two open leg grooves 30b after extension and insertion can be narrowed and the heat insulation performance can be suppressed, it is desirable.

  (B) is a state of (a) in which the finishing material (floor board) 60 is disposed from the direction of the arrow to push in the heat insulating material 1 and expand, fit, flush, and expand between the structural materials. It is sectional drawing which is suppressing the clearance gap between the finishing material 60 and the heat insulating material 1, while suppressing the clearance gap. In this way, since the insertion of the heat insulating material 1 is realized by using the arrangement step of the finishing material 60 just by pre-inserting, the heat insulating material width is artificially compression-inserted in advance as in the past, Alternatively, it is possible to reduce the trouble of disposing, extending, and inserting the chevron forming portion to dispose the finishing material 60.

  In (c), a side flat portion 1b is provided on one side of the mountain-shaped plate-like heat insulating material 1, and a flat and rectangular inclined band portion 1a is formed on the other side. This is an example. The insertion method of this structure can be preliminarily inserted. For example, the side flat portion 1b is placed between the joists 51, and at least the lower end of the inclined band portion 1a is preliminarily fitted between the joists 51. If the angle forming portion is pushed in without inserting and pre-compressed, it can be easily expanded, inserted, and expanded, and gap suppression and uniformity are ensured.

Example 3
FIG. 3 is a cross-sectional view showing another embodiment of the single plate-shaped plate heat insulating material 1. (A) is composed of a stretched leg groove 30a having an opening on the upper surface side of the first bent portion 1e at the center and an extended connecting portion 1f, and the other two second bent portions 1e are on the upper surface side. The one extended leg opening groove 30b and the one extended leg closing groove 30a opened on the lower surface side are formed to face each other, and the meat connecting portions of the constricted portions of the grooves facing each other are extended and connected. In the embodiment configured as 1f, the heat insulating material width A at the time of expansion in this case corresponds to a distance dimension connecting the center portion of the three expansion connection portions 1f and the end surface in the short side direction, and at the time of preliminary insertion Even if the heat insulating material width B is equal to or less than the dimension V between the structural materials, the heat insulating material width B is expanded at the time of extension, and the gap can be suppressed.

  (B) is sectional drawing which shows another Example of the mountain-shaped plate-shaped heat insulating material 1, Comprising: The extending | stretching leg opening groove 30b and the extended connection part 1f which the 1st bending part of this center part opened on the lower surface side are shown. And the other two second bent portions are formed by the extended leg closing groove 30a opened to the lower surface side and the extended connecting portion 1. Thus, by forming at least one extension closed leg groove 30a and one extension opening leg groove 30b in one heat insulating material 1, the bending elastic stress of the heat insulating material 1 is relieved and the fitting is rich in flexibility. It becomes a heat insulating material form that is easy to insert. In contrast to this embodiment, the same effect can be obtained by forming at least one extended leg closing groove 30a and one extended leg opening groove 30b on the upper surface side. Further, if the cross-sectional shape of the opening bottom portion of the extended leg closing groove 30a and the extended leg opening groove 30b is an arc shape 30c, it is preferable that the legs are easily opened and closed.

Example 4
FIG. 4 is an embodiment in which an inclined band portion 10b and a side flat portion 10c are connected to each other on both sides of the central band portion 10a at the top of the trapezoidal chevron plate-shaped heat insulating material 10 by first and second bent portions. is there. In (a), a flat central belt portion 10a is provided at a substantially central portion, and the first bent portions 1e on both sides thereof are provided with one extension closed leg groove 30a opened on the upper surface side, and opened on the lower surface side. The extension leg opening groove 30b is formed opposite to each other, and the closing leg groove 30a and the extension connecting part 1f composed of a meat connecting portion narrowed by the opening leg groove 30b are provided. The second bent portion is provided with one extended leg closing groove 30a opened on the upper surface side, and one extended leg opening groove 30b opened on the lower surface side is formed to face each other. The cross section which consists of the extended connection part 1f which becomes. (B) is a heat insulation construction in which a finishing material 60 is disposed from above the angle plate-like heat insulating material 10 preliminarily inserted between the structural materials 51 shown in (a), and is expanded, inserted, and expanded. It is a cross section.

  (C) is sectional drawing of the elastic ditch | groove 3a formed along the long side direction opened on the upper surface of the side flat part 10c shown to (a), (b). The depth of the concave groove 3a is made shallower from the end face in the long side direction toward the center, and the elasticity of the elastic concave groove 3a in the long side direction is changed according to the groove depth, so that the elastic retention between the structural members in the long side direction is maintained. It is possible to suppress the strength of strength and the deterioration of elasticity. In this example, the depth of the end face in the long side direction is 2/3 of the heat insulating material thickness T and the end face is halved to form a gentle arc shape. This configuration is not limited to the chevron plate-like heat insulating material 10 of the present invention, and is widely effective for elastic grooves and bent grooves formed on conventional plate-like and mountain-shaped plate heat insulating materials. Applicable.

Example 5
FIG. 5 is an embodiment in which the entire cross section of the chevron plate-like heat insulating material 20 is formed in a single mountain shape, and (a) is a perspective view thereof. The bent portion 1e at the substantially central portion on the upper surface side of the heat insulating material 20 is made to oppose one extended leg closed groove 30a opened on the upper surface side and two extended leg opened groove 30b opened on the lower surface side. Bending elastic stress and flexibility are eased by forming and forming the extended connecting portion 1 composed of a meat connecting portion narrowed between the grooves, and inclined bands inclined downward on both sides thereof The part 20a is formed. Furthermore, the upper edge width U of the both end faces is made larger than the lower edge width T, and the lower edge width U is pre-inserted and expanded, inserted, and expanded to ensure clearance suppression and uniformity. It is done.

  Further, on the upper surface side of the figure (a), a concave groove 3e parallel to the long side direction and a non-parallel V-shaped concave groove 3e described in Patent Document 9 by the present inventors are formed, and the concave groove 3e is further formed. A concave groove 3d is formed continuously by refracting the side surface side of the groove substantially parallel to the short side direction. Further, the grooves 3a and 3e are provided with discontinuous portions 2f so that compression elasticity can be exerted in the long side, short side, and diagonal direction of the heat insulating material 20, and the groove on the lower surface side is parallel to the long sides. Two strips 3b and three height-adjusting projections 1k (details are shown in FIG. 10) are provided. With this configuration, even in the case of a plate-like heat insulating material made of hard foam synthetic resin such as foamed polystyrene with poor flexibility, compression elasticity in four directions of long side, short side, diagonal, and height is possible. Thus, the function of the chevron plate heat insulating material of the present invention is further amplified and improved.

  (B) is a cross-sectional view taken along the arrow A in (a) and shows a dimensional relationship when preliminarily inserted between the joists 51. The opening dimension Z of the closed leg groove 30a at the time of expansion is desirable because when the heat insulating material is expanded in a flat plate shape, the opening dimension Z is closed and zero, so that it can be prevented from being deformed into an inverted mountain shape below the heat insulating material 20. Further, the distance L between the extension leg grooves 3b at the time of extension 2 is equal to or less than the thickness of the heat insulating material, and is within the propagation range of stress that causes the extension leg legs 3b to open when the angle forming portion is extended. It is necessary to form. The elastic grooves 3a, 3b, 3e, 3 are formed mainly for compressive elasticity by a horizontal force acting on the width, length, diagonal, etc. of the heat insulating material.

  The width Y of the inclined band portion 20a in which both sides are inclined downward is substantially equal to 1/2 of the structural material width dimension V, or the width of the heat insulating material inserted in a state where the concave grooves 3a and 3b are compressed. A range that does not exceed the width V between the structural materials is desirable. In addition, the inclination θ of the inclined band portion 20a is selected from the distance between the structural members to be inserted, the thickness of the heat insulating material, and the insertion workability, but it is 5 for a normal joist, roof heat insulating material and large pulling heat insulating material. The degree of 10 to 10 degrees is desirable from the viewpoint of formability, storability, extension, and insertion workability.

  The thickness R of the plate-shaped heat insulating material 20 and the height Q of the height adjusting projection 1k are designed to be approximately equal to or somewhat larger than the maximum height of the joist 51 to be applied. The width between the lower ends of the plate-shaped heat insulating material 20 (referred to as the plate-shaped heat insulating material lower end width) T is smaller than the gap width V between the joists, and the width between the upper ends of the plate-shaped heat insulating materials 20 (plate-shaped heat insulating material). U) (referred to as the upper end width) is formed larger than the joist gap dimension V.

The above dimensional relationship is summarized as follows.
Total thickness S of the plate-like heat insulating material 20 = plate-like heat insulating material 20 thickness R + height adjusting convex portion 1k height Q
Joist height P ≦ plate-like heat insulating material 20 total thickness S
Joist width dimension V
Plate-like insulation top edge width U
Plate-like insulation lower end width T
Angle-shaped angle theta plate-like insulation upper end width U> joist width V> plate-like insulation lower end width T
Width between joists V> width Y × 2 of inclined portion 20a

  (C) shows the air deterioration in the concave grooves 3a and 3b caused by the elastic deterioration of the elastic concave grooves 3a and 3b in FIG. It is a fragmentary top view which shows the Example of the discontinuous part 2f provided in order to suppress the heat insulation fall by a flow. If the thickness of the discontinuous portion 2f in the planar direction is excessive, the elastic stress becomes excessive and the insertion workability is deteriorated. Therefore, it is important that the discontinuous portion 2f is easily bent and molded.
