Description

[Detailed Description of the Invention] The present invention relates to a new fixed connection structure for a cap that is attached to a roof parapet.

As is well known, caps are installed to waterproof roof parapets and prevent the occurrence of cracks, etc. However, with the conventional fixed connection structure of the caps, the waterproofing of the connecting parts of the caps is insufficient. For,
There was a problem in that rainwater infiltrated through this connection, causing cracks in the parapet.

In order to solve this problem, we have recently
The fixed connection structure of Kasagi as shown in Figure 6 has come to be adopted by some manufacturers. That is, in this case, a pair of fixing fittings 101, 101 are fixed with screws to the upper surface of a parapet 100 on the roof, and a waterproof joint material 102 in the shape of a bent corrugated plate is placed on top of the fixing fittings 101, 101.
103,1 on both sides.
03, and as shown in FIG.
105 is elastically engaged with the lower end surfaces of both side plates of the fixture 101 to form a fixed connection structure.

With such a structure, both Kasagi 103,
Rainwater that has entered from the connection part 103 is caught by the corrugated waterproof joint material 102, flows through the troughs of the waves of the joint material 102, and is drained onto the roof. do not have. However, since the waterproof joint material 102 is required, compared to the conventional structure,
The disadvantage is that the number of parts increases, which increases cost and effort. Also like this Kasagi 103
If the structure is such that the L-shaped lower edges 105, 105 of the side plate portions 104, 104 are elastically engaged with the lower end surfaces of both side plates of the fixing metal fitting 101 by force-fitting, the both side plates, such as a synthetic resin cap, can be elastically expanded. Another drawback is that only flexible caps can be used, and fixed connections cannot be made with caps that cannot be elastically deformed and are made of inorganic materials such as cement.

The present invention was developed in view of the above circumstances, and its purpose is to eliminate the need for any components such as waterproof joint materials, save labor and cost during construction, and to create a structure that cannot be elastically deformed. To provide a very useful fixed connection structure for a capstone, which can be easily fixedly connected to a capstone and can satisfactorily prevent rainwater from entering from the connection part.

That is, in order to achieve such an object, the present invention fixes a fixture having a pair of cylindrical parts arranged side by side with an interval on a substrate to the upper surface of a rooftop parapet, and has a cross section that covers approximately the upper part of the parapet. Covering one end of the inverted U-shaped cap over one cylindrical portion of the fixing device, and placing the end of the other cap over the other cylindrical portion,
The gist of this is that a fixing pin is inserted into each cylindrical part of the fixture by penetrating the side plate part of each Kasagi end part, and this will be explained in detail below with examples. do.

Fig. 1 is an exploded perspective view of one embodiment of the present invention;
The figure is a longitudinal cross-sectional view of the same embodiment, and Figure 3 is the - of Figure 2.
It is a line cross-sectional view, where 1 indicates a parapet on the roof, and on the top surface of this parapet 1,
A fixture 2 is fixed at its four corners with four anchor bolts 3.

As shown in FIG.
A pair of flat rectangular cylindrical parts 22, 22 are arranged side by side on the board 1 with an interval, and insertion holes 23 for the anchor bolts 3 are formed in the four corners of the board 21, A concave portion between both cylindrical portions 22, 22 serves as a drainage groove 24. The fixture 2 is made of aluminum, iron, other metals, synthetic resin, or the like.

One cylindrical portion 22 of this fixture 2 is covered with the end of one cap 4 that covers the parapet 1, and the other cylindrical portion 22 is covered with the end of the other cap 4. This Kasagi 4 has an approximately inverted U-shaped cross-sectional shape, and approximately the upper half of both side plate portions 41, 41 is thickened to improve strength. Thick wall portion 42 of 41,
Pin insertion holes 43, 43 are formed in 42.
The thick portions 4 of these side plate portions 41, 41
The dimension L between the inner surfaces of 2 and 42 and the cylindrical portion 2 of the fixture 2
2, the vertical dimension H of the thick portion 42, and the height h of the cylindrical portion 22 are approximately the same, and are formed by the thick portions 42, 42 and the Kasagi top plate 44. The cylindrical portion 22 of the fixture is configured to fit into the concave groove portion 45 to support the Kasagi top plate 44. Such a cap 4 is made of aluminum, iron, synthetic resin, cement, etc., and may have a hollow structure for weight adjustment depending on the case.

Further, fixing pins 5, 5 are attached to the cylindrical portions 22, 22 of the fixture 2, respectively, to the side plate portions 41, 41 of both sides.
The pins are inserted through the pin insertion holes 43, 43. This fixing pin 5 has a diameter that is almost the same as the upper and lower inner dimensions of the cylindrical portion 22, and has a screw hole 51 formed at its tip. By tightening the set screw 52 inserted through the pin insertion hole 43 of 41, the cap 4 is irremovably fixed to the fixture 2.

According to the fixed connection structure of the Kasagi of the present invention as described above, the recess between the pair of cylindrical parts of the fixture becomes a drainage groove, so rainwater that enters from the connection part of both Kasagi is caught in this drainage groove. water is drained from both ends. Therefore, without using extra waterproof joint material like in conventional structures, the disadvantage of rainwater seeping into the parapets and causing cracks, etc. is eliminated, and the number of parts is reduced, resulting in savings in construction time and costs. be done. Moreover, since the kasagi is fixed to the fixture using a fixing pin that passes through the kasagi side plate and is inserted into the cylindrical part of the fixture, even if the kasagi is made of cement and cannot be elastically deformed, the kasagi can be fixed securely and securely. Can be fixed easily. In particular, when the cylinder part is formed into a flat rectangular cylinder shape as in the example, in addition to being able to stably support the Kasagi on the top surface of this cylinder part, it is also possible to slide the fixing pin within the cylinder part. Therefore, even if the position of the cap is slightly shifted, it can be easily installed, and even if the cap is expanded or contracted due to temperature changes, it can be satisfactorily absorbed.

As described above, the Kasagi fixed connection structure of the present invention has many remarkable effects and is extremely useful.
