Description

[Detailed Description of the Invention] The present invention makes it possible to install cap wood, which does not undergo thermal distortion and has excellent corrosion resistance, on rising walls such as parapets on the roof of a structure, and the construction cost can be reduced. Regarding Kasagi equipment.

BACKGROUND ART Conventionally, rising walls such as parapets on the rooftops of structures such as steel-framed concrete structures have been covered with metal cap timbers. Since the wood of the hat is exposed to sunlight and wind and rain, a corrosion-resistant metal material is required from the aesthetic point of view. If this is constructed as a Kasagi device using stainless steel or other stainless steel,
When the cap wood expands and contracts in the longitudinal direction depending on the outside temperature, its cross section has a corner part because it is approximately gate-shaped.
Strong thermal stress occurs, causing deformation and strain in various parts of the hat wood, especially the corners. For this reason, expansion joints had to be provided at appropriate intervals in the longitudinal direction.
This construction had the drawbacks of being troublesome and expensive.

Therefore, the present invention fixes receiving metal fittings at appropriate intervals on the rising wall of the roof of a structure, and fixes a synthetic resin-coated steel plate having a substantially gate-shaped cross section on the receiving metal fittings,
The cap wood, which is made of thin stainless steel and has a relatively short length in the longitudinal direction and has a substantially gate-shaped cross section, is polymerized in the longitudinal direction and then fitted and fixed onto the synthetic resin-coated steel plate. The amount of thermal expansion and contraction of the wood cap and thermal stress can be reduced, without the need for expansion joints.
It can prevent the occurrence of thermal distortion, etc., and since it is stainless steel, it has excellent corrosion resistance and a good appearance.Furthermore, the presence of the synthetic resin-coated steel plate on the bottom side prevents corrosion due to battery action, and the steel plate inside Even if the cap wood is thin, it has superior strength with the synthetic resin-coated steel plate, and it is easier and cheaper to construct than using expansion joints. This solves the above-mentioned drawbacks.

The structure will be explained with reference to the drawings.

Reference numeral 1 denotes a rising wall such as a parapet, which is installed on the roof of a structure made of reinforced concrete or the like. Reference numeral 2 denotes a receiving metal fitting having an O-shaped cross section, which is fixed to the rising wall 1 at appropriate intervals (for example, about 50 cm to about 1 m) with bolts, anchors, etc. 3 is a synthetic resin-coated steel plate with a roughly gate-shaped cross section (for example, polyvinyl chloride resin metal laminate, etc.)
The length in the longitudinal direction is also relatively short (for example, about 2 m), and the top of the synthetic resin-coated steel plate 3 is placed on the receiving bracket 2 and fixed with rivets, etc. It is configured to cover the upper inner and outer surfaces of the rising wall 1. The longitudinal ends of the synthetic resin-coated steel plates 3 and 3 are overlapped and fixed with rivets or the like. In FIG. 3, the overlapping location and the mounting location of the bracket 2 are the same, but in general, the overlapping location and
The location is different from the mounting location of the bracket 2. 4 has a roughly gate-shaped cross section, and is made of a thin material (e.g., about 0.2 m/m to 0.5 m/m) made of stainless steel or the like, and its length in the longitudinal direction is also relatively short (e.g., Approximately 2m) is formed. The Kasa wood 4 is
It is fitted onto the synthetic resin-coated steel plate 3 from above and fixed with rivets or the like. Also, the Kasa wood 4,
4 mutual longitudinal ends are polymerized and fixed with rivets etc. in this case as well, and a sealant 5 is interposed as necessary in this overlapped part (3rd
(see figure). As shown in FIG. 3, only the ends of the cap timbers 4, 4 are fixed to each other by polymerization, but the overlapped portions may also be fixed to the synthetic resin-coated steel plate 3 with rivets at the same time. Further, the overlapping portion of the cap timbers 4, 4 and the overlapping portion of the synthetic resin-coated steel plates 3, 3 are provided at positions shifted from each other. In the figure, 6 is a coated metal material made of a thin material such as stainless steel that can be seam welded, and side rising portions 6b, 6b are formed on both sides of the main plate 6a. Reference numeral 7 designates an accessory material in which a rising portion 7b is formed on one side of a flat portion 7a, and a tall vertical portion 7c is integrally formed on the other side. The covering metal material 6 is installed on the roof (slab) of the structure,
The side rising portions 6b, 6b are seam welded together with the tongue piece of a movable hanger fixed on the slab (see Figure 1), and the rising portion 7b of the accessory material 7 provided inside the rising wall 1 and , and the end rising portion 6c of the covering metal material 6 are seam welded to form a covering metal sheet layer. The cap wood 4 is provided on the side of the synthetic resin-coated steel plate 3 so as to cover the upper side of the vertical portion 7c of the accessory material 7.

Next, the effects will be explained.

In the present invention, a cap lumber 4 made of thin stainless steel having a relatively short length in the longitudinal direction and a substantially gate-shaped cross section is overlapped in the longitudinal direction and then fitted onto the synthetic resin-coated steel plate 3. Since it was stuck, the kasa wood 4
The longitudinal length of each sheet is relatively short, so the amount of longitudinal thermal expansion and contraction due to outside temperature can be reduced, and the fact that the material is thin also works synergistically to prevent thermal expansion and contraction. thermal stress can be reduced. As a result, it is possible to prevent thermal distortion, damage, etc. that are extremely likely to occur at the corners of the fixed cap wood 4. Therefore, the present invention can exhibit the great effect of preventing thermal distortion by simply fixing the joint without providing a complicated expansion joint. Since workability is improved in this way, it is possible to provide an inexpensive Kasagi device. Further, the cap wood 4 is made of stainless steel, has excellent corrosion resistance, and prevents thermal distortion as described above, and also has a good appearance. Furthermore, in the present invention, the synthetic resin-coated steel plate 3 having a substantially gate-shaped cross section is fixed on the receiving metal fitting 2 fixed on the rising wall 1, and the cap wood 4 is fitted and fixed thereon. Since the steel material of the synthetic resin coated steel plate 3 is in contact with the steel material through the synthetic resin, that is, there is no metal contact, the contact corrosion current can be reduced.
Can prevent battery corrosion. This means that the cap wood 4 made of stainless steel and the general metal material (for example,
In contact with metals such as Fe, etc., the corrosion rate of the battery is fast;
The present invention prevents loss of durability, etc., and makes it possible to provide a durable Kasagi device. Moreover, even if the cap wood 4 is a thin material, the synthetic resin-coated steel plate 3 as the base material
Since it is made of both materials, it can be made with sufficient strength.

As described above, in the present invention, thermal strain can be prevented against thermal stress, and it is also possible to provide a strong Kasagi device that is less likely to be strained against external forces such as earthquakes.
