Description

[Detailed description of the invention] (Industrial application field) The present invention provides complete rain protection and waterproof treatment for the top end of a parapet, and further functions as a lightning conductor if necessary. This product relates to a holder for holding a metal cap.

(Prior Art) Currently, as an example of a cap for use at the top of a parapet, etc., there is a holder 51 fixed to the top of the parapet P with screws 52 as shown in FIGS. 3 and 4.
A configuration in which an aluminum cap 53 is fitted is most preferably used. In this structure, a gap E open to the outside is maintained between the Kasagi 53 and the parapet top P, creating an equal pressure structure in which wind blows through the inside and outside of the Kasagi. It has a movable structure that is simply fitted into the cap, which prevents water from accumulating and condensation inside the cap, and can absorb the expansion and contraction of the cap and the behavior of the rod.

(Problem to be solved by the invention) However, when a strong wind such as a typhoon blows, if the Kasagi has the above-mentioned configuration, the strong wind W from the outside of the building (curtain wall side) will blow over the Kasagi, as shown by the arrow in Figure 3. It may blow into the void inside the cap 53 and create strong pressure inside the cap. This strong pressure is a long piece of wood called Kasagi 53.
This causes stress concentration on the fixing part 54, which is the screwed part of the holder 51 that holds the holder 51 located outside the building. This could lead to an accident where the cap came off.

The present invention was made in order to solve the long-term functional stability of Kasagi by investigating the occurrence of the above-mentioned problems.

(Means for Solving the Problems) In order to solve the above object, the present invention provides lower folding plates for fitting and locking Kasagi on both sides of the main plate of a required width, which is attached to the top surface of the parapet with a water gradient. A hollow fixing part having an upper and lower surface and both side surfaces in the longitudinal direction of the main plate is formed to protrude downward at a position of the main plate where the water gradient is higher, and the upper part of the fixing part is bent. The Kasagi holder is characterized by having a structure in which a screw hole is formed through the lower surface.

(Function) According to this, the external force due to the wind pressure can be dispersed to the hollow two or more layered component in the fixed part of the holder, and the stress concentrated in the screwed part can be significantly reduced.

(Example) The present invention will be explained below with reference to an example shown in the drawings.

In Figures 1 and 2, reference numeral 1 denotes a holder body made of aluminum, which includes a main plate 2 of a required width that is attached to the top end of the parapet with a water gradient, and caps (not shown) fitted on both sides of the main plate 2. supporting lower folding plate 3;
4, and screw holes 5 and 6 are formed at positions near both sides of the main board 2, and an appropriate length of the main board including the screw holes 5 located on the side with a higher water gradient (outside the building) is It is formed as a hollow fixing part 7 having at least an upper surface 8 formed on the same plane as the plate or at a slightly upper and lower position, both side surfaces 9 and 10 bent downward from the main plate, and a lower surface 11. Screw holes 5a are formed in the lower surface 11 corresponding to the upper and lower surfaces, and water is provided in the main plate at least at both ends of the lower surface 11 and in the vicinity of the other screw hole 6. A protrusion 12 is formed to provide a slope or to make the screw fixation stronger.

In the above, the upper surface 8 of the fixing part 7 may be formed integrally with other parts of the main plate 2, for example, by a cutting die, or the upper surface 8 of the fixing part 7 may be formed by molding, for example, with a cutting die, or the upper surface 8 of the fixing part 7 may be formed by integrally molding with other parts of the main plate 2, or the upper surface 8 of the fixing part 7 may be formed by molding, for example, with a cutting die, or the upper surface 8 of the fixing part 7 may be formed integrally with other parts of the main plate 2, or may be formed by molding, for example, with a cutting die.
Alternatively, the main plate may be bent and integrally formed with another main plate portion, and a plate may be integrally formed on the open upper surface portion by adhesive such as welding.

The holder constructed as described above is used by first fixing the holder main body 1 with screws through the screw holes 5 and 6 at the top end of the parapet, as shown in FIG. If the cap is press-fitted from above the holder, both ends of the cap will fit into the holder by engaging with the lower ends of the lower bent plates 3 and 4 of the holder, maintaining a predetermined gap between it and the top of the parapet. do.

In this way, the fixed part of the holder on the outside of the building has a hollow rectangular cross section, and the stress is dispersed in each part, so unlike a structure that is made of a single plate and must be thick, shear stress The strength against is significantly improved.

In this case, if an insertion part is formed inside both sides 9, 10, and if necessary, a plate can be inserted into the hollow and a core (crosspiece) can be passed to both sides 9, 10. Since the stress is further dispersed, the strength can be further improved.

The above configuration is also excellent in ease of processing and workability.

In the above, the shape of the holder can be changed to various shapes corresponding to various ends of the building that require waterproofing treatment, such as parapets, and is not limited to the shape shown, and it is of course possible to add configurations not shown. It is.

(Effects of the invention) As described above, according to the invention, external force can be dispersed over two or more layers of surfaces without making the wall thickness of the fixing part of the holder thicker than other parts of the holder. Does not cause stress concentration at the stopping part,
It is possible to significantly improve the strength of the fixing part, and to provide a holder that does not cause breakage accidents at the fixing part. Moreover, it is easy to mold and has excellent workability.
