Description

  In the present invention, when a building exterior wall having a through hole parallel to the longitudinal direction is horizontally stretched to form an outer wall, a sealing material is subsequently applied to a vertical joint formed between end faces of adjacent hollow exterior panels. The present invention relates to a vertical joint joiner that prevents the through-hole of a hollow exterior panel from being completely sealed by the above-mentioned method and a joint construction method using the same.

When it is going to comprise the outer wall of buildings, such as a house, with a ceramic industry panel, for example, a dry-type hollow exterior panel, the panel of a standard dimension is stretched and joined, and the longitudinal direction is joined in the state where the end faces were abutted. In this case, in consideration of expansion / contraction due to heat of the exterior material, aging, or dimensional changes due to earthquakes, it is usual to provide a gap (vertical joint) of about 10 mm between the left and right end face parts, and In order to prevent rainwater from entering from the vertical joint portion, a sealing material made of a material having elasticity is usually filled.
Many materials such as modified silicones, polysulfides, polyurethanes, acrylics, and butyl rubbers are used as the sealing material. The change in the gap (joint width) due to the expansion and contraction of the building board after construction is considered to be the elasticity of the sealing material. It absorbs and follows by deformation and prevents the seal breakage of the vertical joint due to cutting or peeling of the sealing material.

  By the way, as for the sealing material filled in the vertical joint, only the end surfaces (opposite bonding surfaces) of the hollow exterior panels disposed on the left and right sides in the filled state are bonded, and the other contact surfaces are not bonded. In the case of a state, it shows high followability with respect to expansion and contraction of the hollow exterior panel. For this reason, a non-adhesive tape is bonded to a sealing material called a bond breaker on the surface area of the ridge of the hat joiner. Bond breakers include water-repellent tape (Patent Document 1), release paper (Patent Document 2), and surface treatment to reduce the surface roughness and make the surface glossy. Various types such as a smooth and smooth resin tape (Patent Document 3) have been proposed.

  As described above, the vertical joint joiner is set on the back side of the vertical joint, and the joint is sealed by injecting a sealing material from the surface into the joint space formed by the protruding portion and the hollow exterior panels on both sides. The vertical joint seal is in contact with the panel through-hole, but it is necessary to fill the vertical joint with a sealing material and hold it with a spatula or the like to provide a tight and watertight seal between the joints. The sealing material becomes elastic material due to the volatilization of the solvent and the progress of the polymerization reaction in 1 to 2 days after construction, but it is extremely soft and fluid at the time of construction, and it is easy even for slight pressure fluctuations Transforms into For this reason, in the case of construction, in many cases, the sealing material is pushed into the through hole of the hollow exterior panel, and both ends of the through hole are completely sealed. Therefore, in order to ensure airtightness and watertightness only in the joints without sealing the through-holes, pressing the spatula of the sealing material requires skill and experience, and work that requires skill and experience in construction. It has become.

When the through-hole is sealed, the air enclosed in the hollow exterior panel through-hole expands as the temperature of the hollow exterior panel rises due to temperature rise or solar radiation, and expands by extruding an uncured soft sealing material, There is a risk that it may become a defect in appearance, sometimes the temperature of the air in the through hole rises and expands, and the sealing material is pushed from the inside to lose the waterproof function of the joint. For this reason, it was necessary to install the sealing material in a time zone with little temperature change. Once a hole has been made in the seal material, not only watertightness is lost, but even the simple expansion of the seal material significantly reduces the commercial value of the building. Some proposals have been made, such as changing the shape of the through hole of the exterior panel, for example, a gourd type or a two-stage method.
However, such changes are inevitable in terms of cost increase and weight increase, and are not effective in the interrelationship between the dimensions of the through holes and the dimensions of the longitudinal jointer to ensure the depth of the sealing material. In many cases, it did not give a complete solution.

Further, as a preventive measure, a proposal has been made to use a hollow exterior panel vertical joint joiner in which a sheet having a tuft-like shape at both ends is pasted on the convex surface of the hat joiner (Patent Document 4). This vertical jointer solved many of the above problems. However, it is good when the hollow exterior panel can be inserted along the end face tufted sheet surface, but when it is necessary to insert the panel from the upper face of the end face tufted sheet, the end face tufted sheet is placed on the lower surface of the panel. The sheet that has been pressed into the end face tufted shape becomes the lower surface of the panel and cannot cover the through hole, and the sealing material is pushed into the through hole of the hollow exterior panel to seal both ends of the through hole For this reason, the construction method was limited.
In addition, it has often been difficult to reduce costs in terms of longitudinal joint joiner production, such as production of end face tufted sheets and sticking to hat joiners.

  The present invention is easy and inexpensive to manufacture, and it is easy to insert the end face of a vertical jointer into the through hole of the hollow exterior panel without being restricted by the construction method and timing of the hollow exterior panel. As a result, it is possible to secure an air passage with the outside air without completely sealing the through-hole of the panel in the sealing material construction, so that the air expanded due to the rise in temperature pushes the sealing material immediately after injection from the inside and inflates it Accordingly, it is an object of the present invention to provide a vertical jointer that can surely prevent the appearance of a building from being significantly damaged, and a horizontal jointing method for a hollow exterior panel using the same.

Has effect That.

  In the present invention, the hollow exterior panel is a hollow exterior panel for housing having through holes 4 parallel to the longitudinal direction as shown in FIG. 4, and is a plate-like panel 3 having a thickness of about 15 mm or more. Many of the edges parallel to the direction have a connectable shape. A plurality of the hollow exterior panels 3 are arranged side by side (by joining the end sides) to form an exterior material, and are fixed to the building foundation surface directly or by lifting or the like with a fastener. In the longitudinal direction, it is necessary to take a joint structure in consideration of expansion and contraction due to the temperature of the exterior panel 3 and temperature change due to solar heat. Although this depends on the length of the exterior panel, the joint width E is usually required to be about 10 mm wide × 10 mm deep considering the elasticity of the exterior panel 3 and the elasticity of the sealing material. There are also vertical joints with a width of 6 mm and a depth of 6 mm.

In this vertical joint, the hat joiner 1 is applied from the back surface, and the sealing material 5 is applied from the front surface side.
Although there is no restriction | limiting in particular as a cross-sectional shape of the joiner (thing which does not attach the sticking type material) used for the hollow exterior panel vertical joint joiner in 1st invention in this invention, Generally the hat joiner 1 shown in FIG. 1 is preferable.
A portion of the hat jointer 1 on the ridge 11 on the side filled with the sealing material, the height of the entire vertical joint joiner being 1/4 to 3/4 of the panel through hole, and corresponding to the through hole The vertical jointer, which has a width of 0.5 to 6 mm wider than the joint width and the width of the part corresponding to the panel plate part is the same as the joint width or -5 mm, and in particular, the pasted type material has an acute angle in cross section. A hollow exterior panel vertical joint joiner may be formed by attaching an inverted trapezoidal soft elastic body 2 whose part width 21 is wider than the joint width E of the hollow exterior panel and whose obtuse angle part width 22 is equal to or narrower than the joint width. preferable.

  As this vertical joint joiner, a joiner such as a conventionally used hat joiner may be used, and a soft elastic body 2 having an inverted trapezoidal cross section is stuck on the ridge. The length A of the side connecting the acute angles 21 and 21 differs depending on the joint width, but needs to be wider than the joint width E. In general, a width 0.5 to 6 mm, preferably 2 to 4 mm wider than the joint width E is used. The length B of the side connecting the obtuse angles 22 and 22 is the same as or slightly narrower than the joint width E, for example, 0 to -5 mm, preferably about -1 to -4 mm. The height of the soft elastic body 2 depends on the thickness of the panel 3 (the thickness of the thinnest part where the through hole 4 is present), but is about 1/4 to 3/4 from the bottom of the diameter of the through hole 4. Adjust to height.

  As a material of the soft elastic body 2, when the panel 3 is pushed in from the upper side of the vertical joint joiner 1 provided with the soft elastic body 2, the soft elastic body 2 is easily deformed and passed through the panel 3, and then the elasticity thereof. As long as the portion corresponding to the through-hole enters the through-hole portion 4 and the opening degree of the through-hole 4 can be narrowed to prevent free entry of the sealing material, its elasticity is not limited. Any elastic material such as foamed polyethylene, polypropylene, fluororesin rubber or rubber can be used.

  The hollow exterior panel vertical joint joiner 12 in the second invention of this application has a height of 1/4 to 3/4 of the panel through hole without using a hat joiner, and the width of the portion corresponding to the through hole is a joint. Longitudinal jointer that is 0.5 to 6 mm wider than the width and the width of the part corresponding to the following part from the panel plate part is the same as the joint width or -5 mm, preferably the acute angle part width 21 in cross section, A vertical joint using a hollow exterior panel vertical joint joiner 21 is an inverted trapezoidal soft elastic body 12 whose width 21 is wider than the joint width E of the hollow exterior panel and whose obtuse corner widths 22 and 22 are equal to or narrower than the joint width E. It is also preferable to use a joiner. In this case, the distance C between the acute angle widths 21 and 21 of the longitudinal jointer section is generally 0.5 to 5 mm, preferably 1.5 to 3 mm wider than the joint width E. Further, the length D of the side connecting the obtuse angles 22 and 22 is the same as or slightly narrower than the joint width E, for example, an inverted trapezoid of about 0 to -5 mm, preferably about -1 to -3 mm. The independent type material 12 adjusted to have a height of about 1/4 to 3/4 from below is used as a vertical jointer.

  As the material of the independent type material 12, when the panel 3 is pushed from the upper side of the vertical joint joiner provided with the independent type material 12, the independent type material 12 is easily deformed to pass through the panel 3, and thereafter, due to its elasticity. The elasticity is not limited as long as the portion corresponding to the through hole enters the through hole portion 4 and the opening degree of the through hole 4 can be narrowed to prevent free entry of the sealing material. Any elastic material such as foamed polyethylene, polypropylene, fluororesin rubber or rubber can be used.

Since the hollow exterior panel vertical joint joiner of the first invention is a product in which a pasting type material is pasted on a hard hat joiner, use the vertical joint joiner as a ruler when positioning the panel. Is possible.
On the other hand, the hollow exterior panel vertical joint joiner of the second invention is composed of a soft elastic body, so that it is lighter than the hollow exterior panel vertical joint joiner of the first invention and has the advantage of being inexpensive.
Both of the hollow exterior panel vertical joints have the same elastic shape in the length direction, so they can be easily manufactured at low cost by extrusion, and the non-adhesive treatment is easily and reliably performed because the shape is not complicated. Is possible.

  When using a hollow exterior panel vertical joint joiner with a patch type material on the ridge of the hat joiner or a vertical joint joiner that is an independent type material without a hat joiner, the sealing material enters the through hole of the hollow exterior panel. Can not be completely prevented, but even if the portion corresponding to the through hole of the soft elastic body enters the through hole, the height is below the through hole, so the through hole is not completely sealed and a void remains Therefore, even if the temperature of the hollow exterior panel rises, there is an escape route for the expanded air from the inside of the through hole, so that the sealing material is completely expanded or blown out even when the sealing material is uncured. Can be prevented.

  According to the horizontal joint structure of the hollow exterior panel using the vertical joint joiner of the present invention, a passage through which air can flow is formed between the through hole and the vertical joint joiner, and the hollow exterior panel side is formed inside the joint. Between the end face and the vertical joint joiner is formed a vertical air passage that penetrates in the vertical direction of the joint portion and opens upward and downward, so these air passages communicate with the through holes of the hollow exterior panel, The air in all the through holes can be easily ventilated with the outside air, and even if the air in the through holes expands due to temperature changes, this air passage will push up the soft sealing material at the initial stage of construction and swell It can be surely prevented.

  The hollow exterior panel vertical jointer of the present invention is not only lightweight, but even a worker with a low level of skill in filling a sealing material can surely perform construction with high air tightness and water tightness, workability It is a hollow exterior panel vertical jointer that is stable in effect.
