Description

  The present invention relates to an exterior tool used for the exterior of a base material surface, and further to an exterior member, in particular, an exterior structure using a heat insulating material, a waterproof material, and the like, and an exterior method.

A roof plate made of a thin metal plate is known (for example, see Patent Document 1). In such a roof plate, an exterior material such as a heat insulating material or a waterproof material is used in order to prevent heat intrusion due to solar heat or the like, inundation due to rainfall or the like, noise, and the like (see, for example, Non-Patent Document 1).
JP-A-8-21043 National Santac waterproof construction business cooperative, "Polymeric plasticizer vinyl chloride resin-based waterproof sheet SANTAC IB Santac IB metal ground insulation roof construction PDF", [online], January 2006, Hayakawa Rubber Co., Ltd. [September 2006] Search on May 15], Internet <URL: http://www.santac.or.jp/kinzoku/main.html>

  When a thin metal plate is used as a base, and a heat insulating material and a waterproof layer are constructed on the upper part by a machine fixing method, the heat insulating material and the waterproof material are provided at predetermined intervals, and a disk-shaped PVC steel plate (hereinafter referred to as a disk steel plate) is applied to the base metal plate. ) And screws. FIG. 4 shows a cross-sectional view of an example of the exterior structure obtained by such a machine fixing method. The exterior structure 101 includes a roof frame 102, a metal base (roof board) 103 thereon, a heat insulating material 104, and a waterproof sheet 104. The heat insulating material 104 and the waterproof sheet 105 are made of metal base 103 by screws 106 and a disk steel plate 107. Fixed on top. The reinforcing sheet 108 is pasted on the disk steel plate 107.

  In the machine fixing method, the waterproof layer is not fixed to the entire surface of the base, but because of the partial fixing, the sheet between the disk steel plates is lifted by the negative pressure of the wind, and the upward force is transmitted to the screw. At this time, horizontal and vertical forces are intermittently applied to the screw, and a force that shakes the screw in the entire circumferential direction is applied. Here, when the wind pressure exceeds the design, metal fatigue occurs at the contact portion between the thin metal plate and the screw, and the screw hole expands. For this reason, the binding force of the screw is reduced, and the screw may be pulled out by the force in the vertical direction. FIG. 5 is a cross-sectional view of such an example of the exterior structure, and shows the waterproof sheet 109 that has been lifted by receiving the stress A due to the negative pressure of the wind. In such a state, the screw 106 is swung back and forth and left and right in the B direction, and the metal base 103 causes material fatigue.

  The problem to be solved by the present invention is that mechanical material fatigue tends to occur with respect to the fixed portion of the exterior member.

  The present invention is an exterior tool used for exterior of a base material surface, comprising a frame and a fixing member, the frame penetrates the exterior member, and the lower end of the exterior member and the frame is made of the base material by the fixed member. The present invention relates to an exterior tool, an exterior structure using such an exterior tool, and an exterior method, the main feature of being fixed to the surface.

  The present invention uses a frame as a fixing member for an exterior member, so that even if vibration is applied to a fixing bracket such as a fixing screw, the fixing screw or the like is difficult to swing and difficult to come out, and it can be used for a long time as a fixing means for the exterior member. This is based on the finding that it exhibits a stable fixing function.

  Since the exterior tool of the present invention uses a frame as a fixing tool, there is no physical material fatigue at the fixing part due to the shaking of the fixing metal etc., and there is an advantage that stable fixing lasts for a long time. is there.

  The present invention achieves the object of making it difficult to come out even when vibration is applied to the fixing screw, by using a frame as a fixing tool, suppressing the occurrence of material fatigue and without impairing workability.

(1) (Exterior structure)
FIG. 1 is a cross-sectional view showing an exterior structure of an example of the present invention. As shown in FIG. 1, the exterior structure 1 includes exterior members 3 and 4 and a fixture 5 on a base material 2. The base material 2 is a thin metal plate or the like provided on the housing 2A. The fixing tool 5 includes a frame body 6 and a fixing member 7. The frame body 6 penetrates the exterior members 3 and 4, and the lower end portion 6A of the exterior members 3 and 4 and the frame body 6 is the base material 2 by the fixing member 7. Fixed to the surface.

  In the exterior structure 1, the frame 6 is in contact with the base material 2 by the area defined by the lower end 6A, and the fixing member 7 is shaken by the three-dimensional shape of the bottom and sides of the frame 6. The force of the direction C to suppress works and the material fatigue in a fixed part is prevented.

  As shown in the conventional exterior of FIGS. 4 and 5, fixing with only screws or a disk-shaped steel plate means that the fixing part is in the horizontal direction when the plate that is fastened like a thin metal plate or the like is thin It becomes vulnerable to the force (vibration) of On the other hand, as shown in FIG. 1, by installing a frame body as a roll preventing material around the screw, the fixed portion is less swayed and the fixing reliability is increased.

  Further, the cylindrical case as the frame body widens the grounding range of the fixed portion sandwiched between the disk-shaped steel plate and the base iron plate, thereby preventing rolling. Further, by providing a thickness at the lower part of the cylindrical case, the width of the fulcrum of rolling is widened, thereby further enhancing the effect.

  When a heat insulating material or the like is fastened together with a disk-shaped steel plate to a thin steel plate with a screw, if the screw is tightened too much, the screw hole expands (so-called “fool hole state”), and a predetermined pulling strength cannot be obtained. This occurs because an exterior member such as a heat insulating material is soft and can be squeezed until the disk-shaped steel plate sinks. In the present invention, if the cylindrical case is equivalent to the thickness of the exterior member, it acts as a tightening control when the disk-shaped steel plate is attached with screws, so that the above does not occur.

(2) (Base material)
It is a base material for exterior. Although it is not limited, in particular, it is a base material in which material fatigue at the fixed part due to its fixing bracket etc. is a problem, thin plate, metal plate, etc., roof plate, outer wall plate, etc., heat insulating material, waterproof material, etc. It is necessary to construct the exterior member. Typically, the roof plate is made of a folded metal plate. The metal plate has a thickness of 0.8 to 1.6 mm, for example.

(3) (Exterior tools)
Used for the exterior of the surface of the base material. The exterior tool can include a fixing tool, and is mainly used to fix the exterior member to the surface of the base material. In addition, members usually required for exterior construction can also be included.

(4) (Exterior material)
It can consist of well-known exterior members, such as a heat insulating material, a sound insulation material, a sound insulation material, and a waterproof material. It can be comprised from various shapes, materials, etc., and is not particularly limited. It may be a member that exhibits each function such as heat insulation, soundproofing, and waterproofing, and may be used alone or in combination, or in a single layer or a plurality of layers.

  As the outermost layer of the exterior member, a waterproof material such as a waterproof sheet is used. In the case where a plurality of exterior members are stacked and applied, a plurality of exterior members may be applied separately, but may be applied at a time. The exterior member can have a through-hole for the frame body, but the hole or the like is not particularly essential as long as the material is such that a frame body described later is inserted into and penetrates the exterior member.

(5) (Fixing tool)
A frame and a fixing member are provided. Of the fixtures, the frame body may be incorporated in the exterior member in advance, or the exterior member and the frame body may be integrated to form the exterior member. The frame passes through the exterior member. The lower end of the frame is fixed to the surface of the base material by a fixing member.

(6) (Frame)
It functions to prevent the fixing member from shaking and to prevent material fatigue at the fixing portion due to the shaking of the fixing member. There are no particular restrictions, and various shapes and materials can be used. Various things can be used as long as the fixing material required for fixing by the fixing member, the strength, the mechanical material fatigue at the fixing portion due to the shaking of the fixing member can be suppressed, and the fixing member can be prevented from coming off.

  The lower end portion of the frame body is in contact with the base material, and a fixing area with the base material of the exterior member is defined in the frame, and the base material can be sufficiently fixed by the area. The frame has a fixed stability with the base material due to the three-dimensional shape of the frame, has excellent resistance to shaking of the fixing member, and simply increases the thickness of the base material with another plate, This is different from the means for increasing the durability of fixing by suppressing the shaking of the fixing bracket at that portion.

  The lower end of the frame defines a fixed area for the base material and suppresses material fatigue due to the shaking of the fixing member in the frame part, but it is as wide as possible in the area as well as the frame part. In terms of area, the frame body and the base material are preferably fixed over the entire fixed area. For fixing, mechanical fixing, pressure bonding, adhesion, or the like is used, and there is no particular limitation, and it can be used alone or in combination.

  The frame body may be a case-like object such as a housing or a cylindrical body, but preferably has a bottom portion, particularly a thick bottom portion, so that the fixing strength with the base material by a fixing bracket or the like is increased. In this sense, the frame body is preferably a box-shaped body having a substantially U-shape or a substantially U-shape when viewed in a longitudinal section. In addition, the cylindrical shape and the box shape are not limited to a circular shape when viewed as a cross section, and include shapes such as a rectangle, an ellipse, and a bowl. The material of the frame is preferably metal, plastic or the like, but is not particularly limited as long as it exhibits a certain degree of rigidity.

  The frame can have a notch on its side. A frame, for example, a cylindrical case, is preferably provided with a spiral groove or the like on the periphery or bottom so that it can easily penetrate an exterior member such as a heat insulating material, and the tip diameter is slightly smaller. Is even better. The upper end portion of the frame body can have a collar portion that covers the surface of the exterior member, and the exterior member can be crimped to the base material by the collar portion.

  The frame can be fixed to the exterior member itself. The fixing between the frame body and the exterior member itself is not particularly limited, and it is possible to use means such as unevenness on the outer surface of the frame body, mechanical fixing with a screw between the frame body and the exterior member, locking, adhesion, or the like. it can. In this sense, the frame body may penetrate the exterior member in advance and be fixed to the exterior member. Further, the frame body may be fixed to the exterior member together with the fixing to the base material by pressing the frame body from the surface of the exterior member and the frame body in the direction of the base material using a wide pressing plate described later.

(7) (Fixing member)
As long as the strength necessary for fixing the frame and the exterior member is obtained, there is no particular limitation, and various shapes and materials can be used. A base material such as a thin steel plate is formed with a fixing area defined by the lower end portion of the frame body and a fixing portion by the bottom portion of the frame body, and sufficient fixing strength can be obtained in these areas.

  As the fixing member, when the frame is a box-like body and has a bottom, an adhesive may be used, but it is more preferable to use a fixing metal fitting such as a screw. Even if the lower end of the frame is open or has a bottom, if the bottom is open, the head of a fixing bracket such as a screw is moved more than the opening by a plate-like body such as a washer. It is preferable to design a wide fixed area by widening and covering the opening at the lower end of the frame body from the top, or by making the area comparable to the area of the opening.

(8) (Presser plate)
The exterior tool or the fixing member thereof can include a presser plate, preferably a presser steel plate. The pressing plate can have an area covering the upper end of the frame and / or the surface of the exterior member in the vicinity thereof. The presser plate can hold the upper end of the frame and / or the surface of the exterior member, and fix the lower end of the frame and the exterior member to the base material. As described above, the press plate is used to fix the exterior member together with the frame between the press plate and the base material from above the frame, and in this sense, the press plate is a kind of fixing member. is there. The presser plate can fix the exterior member to the base material by passing the fixing bracket through the frame body using a fixing bracket such as a screw from above.

  The presser plate is not particularly limited and may be various as long as it covers the surfaces of the frame and the exterior member and stable fixation of the frame and the exterior member is obtained. Depending on the shape and material of the exterior member, press plates designed in various shapes and materials can be used.

  As the presser plate, a steel plate, particularly a disk-shaped steel plate 8 as shown in FIG. 1 can be used. As the steel sheet, by using a vinyl chloride steel sheet coated with a vinyl chloride resin on its surface, as shown in FIG. 1, a waterproof sheet such as a reinforced sheet 9 is simply pasted on it by thermal fusion or the like. be able to.

  As shown in FIG. 1, a frame, for example, a cylindrical case is screwed into and penetrated through an exterior member, and preferably locked, and the frame and the exterior member are fixed to a predetermined position of the base material by a presser steel plate. be able to. The fixing with the presser steel plate is performed by a fixing member from above the presser steel plate. At this time, if a fixing bracket such as a screw is used, the base material, the frame body, and the exterior member can be fixed simultaneously by a single fixing.

FIG. 2 is a cross-sectional view showing one step of the exterior method of the present invention. FIG. 3 is a sectional view showing another process of the exterior method of the present invention. In the drawings, the same reference numerals denote the same members.

  In order to apply an exterior to the base material, first, (a) an exterior member and a fixture are prepared. For example, the exterior member is as described above, and the fixture includes the frame and the fixing member as described above. Next, as shown in FIG. 2, (b) the frame 6 is passed through the exterior members 3 and 4. Further, as shown in FIG. 3, (c) the lower end 6A of the frame body 6 and the exterior members 3 and 4 are fixed to the surface of the base material 2 by the fixing member 7. In this way, an exterior structure as shown in FIG. 1 can be obtained.

  As shown in detail in FIG. 3, the fixing member 7 can use the disk-shaped steel plate 8 together to fix the exterior members 3 and 4 and the frame body 6 to the base material 2 from above. In the state shown in FIG. 2, the lower end portion 6A of the frame body 6 can be fixed to the surface of the base material 2 by another fixing member, for example, an adhesive, a fixing bracket, or the like.

  Mainly, the exterior member 3 represents a heat insulating material, and the exterior member 4 represents a waterproof material, but if necessary, when fixing a plurality of exterior members, they can be separately fixed, for example, a waterproof sheet, etc. Can be applied after another exterior member such as a heat insulating material is once fixed to the base material. Although not particularly clear in the figure, if a notch groove is provided on the side surface of the frame body, the frame body can be inserted while being rotated as necessary and inserted into the exterior member.

  It is not limited to the case where material fatigue of the fixed part due to the shaking of the fixing bracket becomes a problem. By using the frame as a fixing tool, high fixing strength can be obtained, and by using the presser plate together, fixing of exterior members, etc. It can be applied to various uses where simple workability is essential.
