Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for attaching a capstone to the rising part of a parapet or the like formed of concrete or the like around the roof of a building.

[Prior art]

Concrete parapets installed on the rooftops of buildings are exposed to changes in the natural environment such as wind, rain, snow, solar heat, dew, and icing, so their surfaces are susceptible to damage. A reverse channel-shaped metal cap made of extruded aluminum alloy or the like is often attached to the upper end with the main purpose of increasing the height.

FIG. 1 shows a state in which a capacitor C is attached to a parapet P by a conventional method. As shown in this figure,
The method of attaching the Kasagi uses a large number of holders H.
Kasagi C has hanging pieces 2 attached to the holder H at the lower ends of both sides in advance.
. It can be hung on the bottom edge of 4 so that it does not come off.

[Problem that the invention seeks to solve]

However, according to the conventional method, since the load of the Kasagi C is supported by the holders H placed at appropriate intervals,
When an excessive load is applied between the holders H, the space between the holders H is crushed, and damage caused by accumulated snow is particularly common in areas with heavy snowfall. Furthermore, since there was a space between the parapet P and the Kasagi C, there was a risk of the parapet being blown up by strong winds.

In order to prevent such damage and accidents, the number of holders was increased, or mortar was piled up high to the top of the holders before attaching a cap to the parapet.

However, even if this is done, the Kasagi will not come into contact with the holder in the center due to the shape of the recess 3 in that part, and the edge part 5 will remain a space in any case, so it is impossible to take all possible measures against the load. do not have. In addition, the surface where the Kasagi is in contact with the holder wears out due to repeated expansion and contraction due to temperature differences.
There was a risk that the initially calculated strength would be lost due to wear and that it would be blown off or crushed.

In addition, the alumite coating on the surface of the Kasagi wears out due to repeated friction with the mortar as it expands and contracts, and this wear causes corrosion, causing it to lose the strength necessary to prevent accidents.

In view of the above-mentioned circumstances, the present invention is designed to completely fill the internal space of a Kasagi with a filler.

The purpose of this invention is to provide a method for attaching a capstone that provides sufficient pressure resistance and does not blow away even in strong winds.

[Means for solving problems]

The structure of the present invention to achieve the above object is to divide a metal cap into several vertical pieces and extrude them, and place cap holders at appropriate intervals on the upper end of a rising part of a parapet, etc. After it is fixed, assemble the individual pieces into the holder one by one and assemble the Kasagi thereon, and each time you assemble the single pieces into the holder one by one, a hard plastic foaming liquid is injected between the single piece and the rising part. The gist of this paper is a method for attaching a cap to a rising part of a parapet, etc., by filling a hard plastic foam between the cap and the rising part.

As a hard plastic foam, a hard urethane foam that exhibits self-adhesion to metals, concrete, etc., and has excellent water resistance and chemical resistance is desirable for use because it can obtain a large bonding strength with parapets and caps.

[For production]

According to the above-mentioned method of attaching Kasagi, each time the Kasagi is assembled one by one into the holder, a hard plastic foaming liquid is injected under the Kasagi.
Hard plastic foam can be evenly filled between the rising part of a parapet etc. and the cap.

By the way, if the cap is integrally molded, even if you inject a hard plastic foaming liquid under the cap through both the openings on the roof and the outside of the roof, the foaming liquid will leak into the center of the mountain and the hollow part of the edge. , because the holder does not reach the area, a gap is created in that area.

In areas where voids were created, the expected strength against the load placed on the top of the cap could not be obtained.

However, according to the above method, the work can be easily done without creating any voids.

〔Example〕

Embodiments of the method of the present invention will be described below with reference to the drawings from FIG. 2 onwards.

FIGS. 2 to 7 show one embodiment.

This is a case where a capacitor C is attached to a parapet P installed on the roof of a building using a holder H, and the capacitor C is composed of a combination of a first unit C and a second unit C2 made of extruded aluminum alloy members. do.

The first unit C□ has a cross-sectional shape consisting of a top plate lO and an outer plate 11, and has a raised hollow edge 12 at an L-shaped corner.
This is provided. In addition, a second unit C is attached to the inner end of the top plate lO.
Two connecting pieces 13 are provided, a connecting groove 14 is formed in the connecting piece 13, and a slight engagement edge 15 is protruded from the lower edge of the connecting groove 14. Furthermore, a locking piece 16 is provided at the lower end of the outer side 11 and projects inward.

The second unit C2 corresponds to the inner plate corresponding to the outer plate 11 of the first unit C, and has a hook-shaped connecting piece 17 that hangs on the connecting groove 14 at the upper end, and corresponds to the outer hooking piece 16 at the lower end. An inner hooking piece 18 is provided.

The holder H is provided with leg pieces 21 and 21 that are inclined in a straddling manner on both sides of a board stand 20 that receives the Kasagi C.

Protrusions 22° 22 are provided at both ends of the board base 20 to directly receive the Kasagi C, and there is a recess 23 between them, and a pair of long holes 24 on the left and right are installed in the recess 23 through which screws 26 and 26 are passed. ,
24 is provided. Furthermore, a low protrusion 25 is formed on the lower surface of the recess 23 to strengthen the tightening of the screw 26.

Next, to explain the procedure for installing Kasagi C, first, embed the female screw 28.28 in the upper end of the parapet P in advance, and attach the holder H by screwing the screw 26° 26 into the female screw 28.28. (Figure 3).

After installing Holder H, the first thing to do is! □ Place only the li body C1 on top of the holder H, and hook the folded piece 16 at the lower end of the outer plate 11 to the lower end of the leg piece 21 of the holder H (
Figure 4). In this state, the parapet P and the first unit C1
Since the space 29 has a space 29 between it and the top plate 10, and the space 29 opens substantially straight to the rooftop side, the nozzle pull of the injection gun G can be deeply inserted into the space 29 from the opening 30 of the space 29.

Although the hard plastic foaming liquid is also injected from the opening 32 on the outside of the roof using the injection gun G, it is desirable that the opening 32 be covered with a plate 33 or the like to prevent the foaming liquid from leaking from the bottom.

After filling the hard plastic foam 35 between the parapet P and the first unit C□ (Fig. 5), the first
The second unit C2 is assembled to the unit C□ (FIG. 6), and the hard plastic foaming liquid is injected into the space 36 using the injection gun G again. In this case as well, the nozzle 31 of the injection gun G is inserted through the opening 37 between the parapet P and the second unit C2 on the rooftop side, but a plate 38 is placed on the opening 37 to prevent the foaming liquid from leaking.

In this way, when the first unit C1 and the second unit C2 are combined to assemble the Kasagi C, and the hard plastic foam 35 is filled between the parapet P and the Kasagi C (Fig. 7), the space between them is completely filled. The space within the edge 12 of the Kasagi C and the recess 23 of the holder H are also filled.

In FIG. 8, the connecting groove 14 of the first unit C1 and the connecting piece 17 of the second unit C2 are straight combinations. formed into a shape. In this way, even if the bond between the first unit C1 and the second unit C2 is weak, if the filling material is a hard plastic foam that exhibits adhesive properties with metal, the stable attachment will maintain its condition without coming off due to the bond. do.

In Figure 9, the first unit C is assembled into the holder first.
1 is used on the rooftop side, the second unit C2 is used on the outside of the rooftop, and the first unit C and the second unit C2 are connected to the edge part 12.
It consists of a combination of overlapping shapes.

In Fig. 10, the central top plate 10 is located at the first unit C0.
, the inner panel on the rooftop side is the second unit C2, and the outer panel outside the rooftop is the third unit C1, which is divided into three parts, making it easier to more evenly fill the space between the parapet P and the Kasagi C with the hard plastic foam. It has become.

〔Effect of the invention〕

As explained above, according to the method for attaching a cap of the present invention, the cap made of metal a is divided into several longitudinally divided units and extruded, so that the rising part of the parapet etc. and the cap can be attached. Hard plastic foam can be evenly filled between the caps, so even if an excessive load is applied to the cap due to snow accumulation, there is no risk of it being crushed by it, and wind will not blow under the cap. Therefore, even if the bonding force with the holder becomes weak for some reason, there is no danger of the capstone being blown away by strong winds, and it has the excellent effect of keeping the capstone in a safe adhering state for a long period of time. be.
