Description

Description: TECHNICAL FIELD The present invention relates to a method of fixing a plate material to a base surface of a building and a fixing structure thereof, and particularly to a board surface having low plane accuracy such as a concrete placing surface. The present invention relates to a method and a structure for fixing a plate material substantially parallel to the substrate surface.

<Prior Art> For example, in a reinforced concrete building, a plate material is mounted and fixed for interior decoration on a concrete wall surface (concrete release surface) formed by concrete pouring. The wall surface of the concrete (base surface) to which the plate material is to be fixed should be one plane along the vertical plane due to the design, but the exposed surface of the concrete is the swelling, tilting, etc. of the frame plate during concrete pouring. Due to this, it is unavoidable that a deviation from the vertical plane occurs, and the concrete wall surface also has unevenness during pouring.

If the interior plate material is fixed to the concrete wall surface without taking these into consideration, the plate material may be tilted from the regular vertical plane due to the inclination or unevenness of the concrete wall surface that is the base surface, or the plate material itself may be difficult to fix.

Therefore, when fixing the plate material for interior to the concrete pouring wall surface, the plate material should be fixed along the vertical plane as accurately as possible so that the inclination and unevenness of the concrete wall surface will not affect the fixation of the plate material. Measures are being taken to do so.

This technique is often referred to as flick (terrain) adjustment in the technical field of the present invention (especially in the field), and these conventional techniques will be described in order.

(First Conventional Technology) In the first conventional technology, a plurality of ridges are formed by applying a plaster-based adhesive in a dot-like amount to a plurality of points on an exposed concrete wall surface.

Then, the board material for interior is attached thereon while pressing and adjusting the board material along the vertical plane and along the set reference line in the width direction of the concrete wall.

(Second Conventional Technology) The second conventional technology is as follows.

A rectangular pillar-shaped wood is fixed horizontally to the upper and lower edges of an exposed concrete wall, and several rectangular pillar-shaped timbers are vertically assembled on the concrete wall so as to connect these woods. Make a frame. At that time, the surface formed by connecting the indoor surfaces of the frame is adjusted vertically and along the set reference line in the width direction of the concrete wall.

Then, the plate material for interior is fixed to the indoor surface of the frame by using nails.

At that time, a heat insulating material such as glass wool is put between the exposed concrete wall surface and the interior plate material, except for the portion where the wood frame is present.

(Third Conventional Technology) The third conventional technology is as follows.

Glue an appropriate number of plastic nuts to the exposed concrete wall, or secure with concrete nails, and screw a plastic bolt into each of those nuts. At that time, each bolt is screwed in and out to an appropriate length (projection amount from the nut), and the surface formed by connecting the upper surfaces of the bolts is aligned vertically and along the set reference line in the concrete wall width direction. To Further, those bolts having a structure capable of driving a nail from the end face of the head in the axial direction of the bolt are used.

Then, a plate material for interior is mounted on the head end surface of each bolt using the above-mentioned nail.

<Problems to be Solved by the Invention> First, in the first prior art, since the adhesive between the concrete wall surface and the plate material has higher thermal conductivity than air, wood, etc., the outside of the wall is more than the inside of the wall. When the temperature is lower in the case of (in winter, etc.), of the interior side surface of the plate for interior,
Condensation occurs on the part having the adhesive on the back side, and further, there is a defect that spots or molds occur on the part.

Further, in the second conventional technique, the dew condensation unlike in the first conventional technique does not occur easily, but it has a drawback that the construction is troublesome and the cost is high because a lot of wood is used.

Further, in the third conventional technology, although there is an advantage that it is less likely to cause dew condensation and does not require much labor for construction, cost such as material cost is high, and the thickness direction is increased between the concrete wall surface and the plate material for interior. It requires a considerably large space for screwing the bolts and nuts, which has the drawback of making the room smaller.

The above problems are not limited to the case of fixing the plate material for interior to the concrete wall in the vertical direction, but also the case of fixing the plate material such as gypsum board in the horizontal direction on the base surface such as the concrete ceiling surface. The problem is not limited to the surface, but may occur when the plate material is fixed to a base surface made of, for example, a lightweight ceramic building material.

It is an object of the present invention to make it possible to fix a plate material to a base of a building by a method and a structure in which dew condensation is unlikely to occur, construction is not very troublesome, and cost is low.

<Means for Solving the Problems> The point of the method of the present invention is that a synthetic resin foam that is easy to cut and has appropriate rigidity is used for connecting the base surface and the plate material. It includes a foam cutting step and a plate material adhering step.

The foam adhering step is a step of adhering synthetic resin foam on the plate material to be fixed at a plurality of positions on the projection surface onto the board surface with an adhesive while protruding from the board surface toward the board material. . At this time, it is usual that the tip of each synthetic resin foam is not located on a common plane due to inclination of the reference plane, unevenness, and the like.

The foam cutting step is a step of cutting a plurality of synthetic resin foams in a direction substantially perpendicular to the projecting direction on one reference plane on the synthetic resin foam side, which is planned as an assumed plate surface after the plate material is fixed. As a result, each synthetic resin foam having a variation in the position of the tip end is cut off at the common cutting plane, so to speak.

The plate material adhering step is a step of adhering the plate material with an adhesive over each cut end surface cut along one reference plane of the synthetic resin foam. As a result, the fixed posture of the plate material is determined by the common cut surface (one reference plane) in the foam cutting step.

Further, the structure of the present invention includes the following synthetic resin foam and a plate member fixed to the substrate surface through the following synthetic resin foam.

The synthetic resin foam is provided on the plate material at a plurality of positions on the projection surface with respect to the base surface, and one end of each is fixed to the base surface at different positions on the projection surface with an adhesive. Each of them protrudes at a substantially right angle, and the other end is cut along one reference plane which is the plate surface on the side of the base plate when the plate material is fixed.

Further, the plate member is fixed by an adhesive over the cut end faces of the plurality of synthetic resin foams.

<Advantages and effects of the invention> According to the fixing method and the fixing structure according to the present invention, even if there is inclination or unevenness on the base surface on which the plate material is to be fixed, the inclination or unevenness does not affect the base material. On the other hand, the plate material can be easily fixed in a predetermined posture.

The synthetic resin foam is interposed between the base surface of the building and the plate material to connect them, so that the heat insulation effect is high, and the plate material is locally cooled even when the outside is cold and the inside is warm. It is difficult to cool from the back side and condensation can be prevented. Also,
Since it can be easily cut with a nichrome wire cutter or the like, the labor of construction can be reduced and the cost can be reduced. Further, the space between the base and the plate material does not need to be so large, and no wasted space is generated.

<Example> An example including the method and structure of the present invention will be described below with reference to the drawings.

FIG. 1 shows a cross section of a concrete wall 1 and a floor 2 formed by pouring concrete, with the features thereof being emphasized. As is well known, the concrete wall 1 is made by pouring concrete into the space formed by the frame plates facing each other, and the exposed concrete wall surfaces A, A'provided by each frame plate are ideally vertical planes. It is difficult to match with, and there are some bulges and dents, and some inclination (deviation) with respect to the vertical plane. 1 cm on average
There is a gap in position.

If the indoor side is the concrete wall surface A and the outdoor side is the concrete wall surface A ', the interior plate material 4 (see FIG. 5) is usually fixed to the indoor concrete wall surface A. The following description is an example of a construction process (land adjustment) for that purpose.

First, prior to fixing the plate member 4 to the concrete wall surface A, a plurality of synthetic resin foams (hereinafter abbreviated as resin foams) are bonded to the concrete wall surface A using an adhesive as shown in FIG. The resin foam 3 is, for example, of polyethylene type, polyeprene type, or the like, and it is desirable that the resin foam has relatively small bubbles and appropriate rigidity, and in the case of commercial products, for example, the product name “Kanelite foam” or the product name “ What is called "styrofoam" can be suitably adopted. Further, the resin foam 3 has a rectangular column shape in this example,
It has a sufficient length to eliminate the deviation from the vertical surface of the concrete wall surface A (adjustment of unevenness). For example, a plaster-based adhesive (such as that sold under the trade name "Direct Bond") is applied to one end of each of the resin foams 3, and the resin foam 3 is fixed to the concrete wall surface A by the adhesive. The cross-sectional shape and size of the rigid resin foam body 3 may be appropriately determined, and the number and intervals of the resin foam bodies 3 adhered to the concrete wall surface A per plate material may be appropriately determined. , One example of which is shown in FIG. In the foam arrangement pattern of FIG. 3, nine resin foams 3 are vertically arranged in the central portion of the projection surface of the concrete wall surface A of the rectangular plate material 4 (for example, gypsum board or plywood board), and Nine resin foam bodies 3 are arranged in the up-down direction across the plate materials 4 adjacent to the boundaries between the plate materials 4 adjacent to each other on both sides. The width W of one plate 4 in this example is 909 mm and the height H is 2424 mm.

Next, as shown in FIG. 4, the surfaces formed by connecting the indoor side surfaces of the resin foams 3 are arranged vertically along the vertical direction, and on the left and right sides are set reference lines in the concrete wall width direction. So that each resin foam body 3 has a common vertical cut surface 3A.
Cut more than one reference plane. At this time, by moving the nichrome wire cutter along the vertical common cut surface, each synthetic resin foam body 3 can be easily cut based on fusing by heat. At this time, in order to give the above-mentioned common cut surface (3A) to each resin foam 3, for example, there is the following method. That is, the uppermost resin foam 3 and the lowermost resin foam 3 are connected by a thread stretched in the vertical direction to form a vertical reference body. In addition, a thread is stretched along the horizontal reference line of the concrete wall surface A, and the portion of each resin foam 3 protruding from the one reference plane (3A) specified by these vertical and horizontal reference lines to the indoor side is defined. Use as a cutting fee. Then, the nichrome wire cutter may be moved along the one reference plane 3A (common cutting plane) thus obtained. However, the resin foam 3 may be cut by a method that does not depend on heat, for example, a knife cutter or a saw device.

After completion of such a cutting process, an adhesive is applied to each cut surface of the resin foam 3. Then, as shown in FIG. 5, a plate material 4 for interior use such as a gypsum board or a plywood board is adhered to the cut end surface on the indoor side of each resin foam 3 with the above adhesive.

At that time, between the concrete wall surface A and the plate member 4,
Except where the resin foam 3 is present, a heat insulating material such as glass wool may be added.

The above embodiment is an example for making a wall, but the present invention is not limited to the wall but to the ceiling or any other base surface of the building as long as the base surface needs to be adjusted for unevenness such as unevenness and inclination. Can be implemented. In addition, when fixing the plate material to the ceiling surface,
The common cut surface for each resin foam is often provided by a horizontal surface.

In addition, the foundation surface of the building is the concrete placing surface (exposed surface).
The present invention can be applied not only to a base surface made of brick, steel or the like.

Further, the plate material is not limited to a plaster board, a plywood board or the like, and other plate materials can be used.

Further, the present invention is effectively applied even when the plate material is not fixed to the indoor side of the base, but is fixed to the outdoor side, or even when the plate material is fixed to the surface of the indoor side and the outdoor side which are not distinguished. It is possible.

Further, the present invention is not limited to the case of fixing the plate material in the vertical direction or the horizontal direction, and when the base surface is formed by a slope which is neither a vertical plane nor a horizontal plane in any direction, an arbitrary direction along the slope is provided. It can also be applied to fix the plate in the direction of.

Of course, the present invention can be implemented in a mode in which various modifications are made based on the knowledge of those skilled in the art.
