Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method of installing Kasa wood, which does not undergo thermal distortion and has excellent corrosion resistance, on the rising wall soil such as parabet on the roof of a structure, and which can be installed at low construction cost. Regarding equipment.

Conventionally, rising walls such as parapets on the rooftops of steel-framed concrete structures have been covered with metal caps and wood. Since the wood for the hat is exposed to sunlight and wind and rain, corrosion-resistant metal material is also required. If this is constructed as a Kasagi device using stainless steel (I), when the Kasagi is thermally expanded and contracted depending on the longitudinal direction and the outside temperature, its cross section will have a gate corner 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 was complicated and had the disadvantage of being expensive.

Therefore, in the present invention, a receiving fitting is fixed to the rising wall soil on the roof of a structure at appropriate intervals, and a synthetic resin-coated steel plate having a substantially gate-shaped cross section is fixed on the connecting fitting, and the length in the longitudinal direction is fixed. It is possible to prevent the occurrence of thermal distortion, etc. without providing expansion joints by using relatively short, thin, stainless steel cap wood with a roughly gate-shaped cross section. ,
Excellent corrosion resistance, good appearance, and the presence of a synthetic resin-coated steel plate on the bottom side prevents battery corrosion.
The internal steel plate can also be made durable, and even if it is made of thin capwood, it has superior strength with the synthetic resin-coated steel plate, and it is easier to install than installing expansion joints. Moreover, it is inexpensive and solves the above-mentioned drawbacks.

The structure will be explained with reference to the drawings.

1 is a rising wall of Parapera)%, which is installed on the roof of a structure such as reinforced concrete.

Reference numeral 2 denotes a receiving metal fitting having an O-shaped cross section, which is fixed to the rising wall 1 at an appropriate interval (for example, about 5 ocIL to about 1 m) with bolts, anchors, or the like. 3 is a synthetic resin-coated steel plate (for example, a polyvinyl chloride resin metal laminate) having a substantially gate-shaped cross section, and its length in the longitudinal direction is also relatively short (for example, about 2 mm); The top of the coated steel plate 3 is placed on the receiving metal fitting 2 and fixed with rivets, etc., and the top of the coated steel plate 3 is arranged so as to cover the upper inner and outer surfaces of the rising wall 1 on both sides thereof. 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 receiving metal fitting 2 are the same, but the locations of the overlapping location and the mounting location of the receiving metal fitting 2 are generally different. Reference numeral 4 is a cap wood that has a substantially gate-shaped cross section and is made of a thin material (e.g., about 0.2 to 0.5) made of stainless steel or the like, and its length in the longitudinal direction is also relatively short (e.g.,
Approximately 2 books) are formed. The cap wood 4 is fitted onto the synthetic resin-coated steel plate 3 from above and fixed with rivets or the like. In addition, the mutual longitudinal ends of the cap wood 4, 4 are
They are polymerized and fixed with rivets or the like in this case as well, and a sealant 5 is interposed in the polymerized portion as necessary (see FIG. 3).

As shown in FIG. 3, only the ends of the cap timbers 4, 4 are fixed together 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 wood 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, reference numeral 6 denotes a coated metal material made of a thin material such as a stainless steel material that can be seam welded, and rising portions 6b, 6b are formed on both sides of the main plate 6α. Reference numeral 7 is an accessory material, in which a flat part 7a has a raised part 7b on one side, and the other part 114 has a tall vertical part 7C.
are integrally formed. The covering metal material 6 is installed on the roof (slab) of the structure, and its side rising portions 6b, 6
b They are seam welded together with the tongue piece of the movable hanger fixed on the slab (see Figure 1), and the rising part 7b of the accessory material 7 provided inside the rising wall l and the end of the covering metal material 6 The rising part 6C is seam welded to form a covering metal sheet layer 6. At the side of the wooden cap 4 synthetic resin coated steel plate 3, the upper side of the vertical part 7C of the accessory material 7 is heated. It is provided.

Next, the functions and 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 polymerized in the longitudinal direction and then fitted onto the synthetic resin-coated steel plate 3. Since it is firmly fixed, the length of each piece of the cap wood 4 in the longitudinal direction is relatively short, and the amount of thermal expansion and contraction in the longitudinal direction due to outside temperature can be reduced, and the fact that it is a thin material has a synergistic effect. ,
Even when thermal expansion and contraction occur, the thermal stress generated can be reduced. This makes it possible to prevent severe thermal distortion and damage to the corners of the fixed cap wood 4. Therefore, in the US invention, a great effect can be achieved in that thermal distortion can be prevented by a simple installation of fixing without the need to provide a troublesome expansion joint. Since the workability is superior 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. In the present invention, a synthetic resin-coated steel plate 3 having a substantially gate-shaped cross section is fixed on a receiving metal fitting 2 fixed on a rising wall 1, and a Jζ shade wood 4 is fitted and fixed thereon. Since the steel material of the synthetic resin coated steel plate 3 is in contact with each other through the synthetic resin, that is, there is no metal contact, the contact corrosion current can be reduced and battery action corrosion can be prevented. This means that
A cap wood 4 made of stainless steel and a general metal material (for example, F
The present invention prevents the loss of the components (e.g., etc.) and provides a durable Kasagi device. Further, even if the cap wood 4 is a thin material, it can be made strong enough to withstand fishing parts because it is composed of a painting material with a synthetic resin-coated steel plate 3 as a base material.

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