Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a watertight structure for a joint portion of a large-sized connecting member that can connect the large-sized connecting members to each other in an extremely simple, quick, and watertight manner.

[Conventional technology and its problems]

Conventionally, large-sized (approximately 1 m to approximately 1.5 m in height) chevron-shaped roofing materials with long spans (approximately 10 meters to approximately several tens of meters in length) that were researched and developed by the applicant have been produced in factories.
These are transported to the site, lifted one by one onto the structure or foundation there by a large crane, etc., and placed and fixed across the opposing beams or foundations at the top of the structure. The roof is made of large chevron-shaped roofing materials arranged in parallel and tied together, and has a simple structure with no beams or the like, and the roof itself is the structure. A large chevron-shaped roofing material is divided into multiple (4 members) into large connecting members for the roof and large connecting members for the walls, and each is installed in a chevron shape approximately symmetrically with flanges interposed between them, making it even stronger. Large-scale chevron roofs, so-called mansard-type roofs, have recently been popularly constructed. Incidentally, the large roof connecting members and the large roof connecting members and the large wall connecting members are connected via flanges to simplify connection construction on site. It is possible to insert a gasket to make the flanges watertight, but if the gasket is large and the flange is large, it will be difficult to tighten evenly and the price will be expensive.
Depending on the tightening strength, there are drawbacks such as the lengths of the large roof connecting members becoming uneven, and it is also possible to cover the periphery of the flanges with a cap material, but it is extremely large. In addition, the outer shape of the flange is not just a straight line or a circle, but a polygonal line, which makes it relatively complicated.The price of the cap material becomes extremely high, and the installation becomes troublesome. There were flaws. In addition, simply filling and applying a sealant between the flanges has the disadvantage that the sealant deteriorates early and watertightness cannot be ensured.

For this reason, it is possible to easily and quickly improve the watertightness between the flanges.
Furthermore, there is a strong demand for lower construction costs.

[Means for solving the problem] Therefore, the inventor worked diligently to eliminate the above drawbacks.
As a result of repeated research, the present invention was developed by forming a sealing pocket on the outer periphery of the opposing surfaces of the flanges that secure the large connecting members, which are long and heavy objects with a large cross section, and applying a viscous liquid sealant there. The watertight structure of the joints of the large connecting materials filled with water and coated with a highly viscous liquid sealant to cover the viscous liquid sealant allows the large connecting materials to be connected to each other in an extremely simple, quick and watertight manner. , which solves the above problem.

〔Example〕

Hereinafter, the present invention will be explained based on the embodiments shown in the drawings.

1 to 4 show examples of the present invention, and A is a large connecting member which is made of metal and is a long, heavy object with a large cross section. In a specific embodiment of the large-sized connecting member A, the cross section has a trapezoidal mountain shape, and sloped edges are formed outwardly and upwardly from the bottom of both lower ends, and the overall height of the cross section is about 1 m to 1.5 m, and the width is about 1 m to 1.5 m. 2 m in length, and is long in the longitudinal direction or has a long span.Since a mansard type large mountain-shaped roof is being constructed, the large connecting material A is the roof large connecting material _A1 and the wall large connecting material. It is configured as _A2 . A plurality of reinforcing bones 2 are fixed to the back surface of the outer skin material 1 constituting the large connecting member A at appropriate intervals in the longitudinal direction, and a heat insulating material,
Lighting equipment mounting materials, air conditioning-related mounting materials, decorative panels, etc. have been installed in advance at the factory, but are omitted from the drawings.

The roof large connecting member A ₁ has a long span (approximately tens of meters to several tens of meters), and both roof large connecting members A ₁ and A ₁ are connected in series in the longitudinal direction and are approximately symmetrical. It is formed in the shape of a mountain. Specifically, flanges 3, 3 are fixed to opposite ends of the large connecting members A ₁ , A ₁ of both roof parts, and the flanges 3, 3 are fixed with bolts and nuts 4, etc. As seen, the heights of the flanges 3 and 3 are increased, and are formed in a substantially symmetrical mountain shape. Both end surfaces of the roof large connecting members A ₁ and A ₁ are also
It is formed to be inclined when viewed from the side, and flanges 5, 5 are fixed to the end faces. Also, large wall connecting material
A ₂ is installed vertically or inclined,
This upper end face is formed to be inclined corresponding to both end faces of the roof large-sized connecting members A ₁ and A ₁ , and a flange 5 is fixed to the end face. Large connecting material for the wall
A ₂ and A ₂ are arranged symmetrically opposite each other, and both ends of the roof large-sized connecting members A ₁ and A ₁ are placed between their upper ends, and the flanges 5 and 5 are connected with bolts and nuts. The roof is fixed, and a large mansard-type chevron roof is constructed as a whole. The lower ends of the large wall connecting members A ₂ and A ₂ are pivotally supported on the foundation or the lower wall by pins 6.

A sealing pocket 7 is formed on the outer periphery of the opposing surfaces of the flanges 3, 3 or 5, 5. Specifically, a chamfered portion is formed on the circumferential surface of the flange 3 or 5 on the joining surface side, and when joined with this chamfered portion, a sealing pocket 7 having a V-shaped cross section is formed. Alternatively, although not shown, it may be formed to have a U-shaped cross section or an arcuate cross section. 8 is a viscous liquid sealant, which has a relatively low viscosity;
The main component is a resin-based or rubber-based material, which is also used for adhesion, has excellent watertightness and airtightness, and has good permeability into small gaps.In the experimental example, for example, chloroprene rubber as the main component A viscosity (cps) of about 40,000 to about 120,000 at 20°C is suitable. first. This viscous liquid sealing material 8 is filled and injected into the sealing pocket 7 on the outer periphery of the opposing surfaces of the flanges 3, 3 or 5, 5.
9 is a highly viscous liquid sealant, which has a relatively high viscosity and is mainly composed of a resin or rubber material, which can also be used as an adhesive and has excellent watertightness, airtightness, weather resistance, etc. For example, a material containing chloroprene rubber as a main component and having a viscosity (cps) of about 500,000 to about 1,500,000 at 20°C is suitable. The highly viscous liquid sealant 9 is the viscous liquid sealant 8.
And it is painted so as to cover the peripheral edges of the flanges 3, 3 or 5, 5 in this vicinity. In the embodiment, after a certain amount of time has elapsed for the surface of the viscous liquid sealant 8 to harden (for example, after one hour to several hours)
, the maximum height of the highly viscous liquid sealing material 9 is approximately 3 mm to approximately 10 mm higher than the periphery of the flange 3, 3 or 5, 5.
It is piled up and painted so that it has a diameter of mm. In this way, the joint portions of the large chevron roof, that is, the opposing flanges 3, 3 or 5, 5 are connected in a watertight and airtight manner.

In the above description, the cross section of the large connecting member A is made into a mountain shape, but the cross section is not limited to this, and the cross section may be made into a polygonal shape such as a quadrangle, or a substantially circular shape.

In the figure, 10 is a tie bar, and 11 is a unit beam member.

[Effect of idea]

In the present invention, a sealing pocket 7 is formed on the outer periphery of the opposing surfaces of the flanges 3, 3, 5, 5 that fix the large connecting members A, A, which are long and heavy objects with a large cross section, and By filling the viscous liquid sealant 8 and applying the highly viscous liquid sealant 9 to cover the viscous liquid sealant 8, firstly, the large connecting members A and A can be connected to each other very easily. Watertight connection is possible, and secondly, watertight construction can be performed at low cost.

To explain the effects in detail, in the present invention, especially after filling the first liquid viscous liquid sealant 8,
Since the second liquid highly viscous liquid sealant 9 has been applied, the first viscous liquid sealant 8 has a low viscosity and penetrates into the very small gap between the flanges 3, 3, 5, 5, making it watertight. It can be made into a watertight structure that ensures airtightness. By covering the viscous liquid sealant 8 with the second highly viscous liquid sealant 9, the application can be done in an orderly manner without dripping during the application process due to its highly viscous liquid form. Moreover, the highly viscous liquid sealing material 9 has weather resistance and is not easily weathered, so that the viscous liquid sealing material 8 can be suitably protected. Furthermore, even if the highly viscous liquid sealant 9 becomes weathered due to long-term use, the viscous liquid sealant 8 that ensures watertightness and airtightness can be covered, so it will remain watertight and airtight for an extremely long period of time. It is possible to provide a watertight structure for the joints of the large connecting members A and A with excellent properties.

In addition, its watertight construction is easy and inexpensive.
That is, to ensure watertightness between the roof large connecting members A ₁ and A ₁ and between the flanges 3, 3, 5, and 5 that connect the roof large connecting members A ₁ and the wall large connecting members A ₂ . It is possible to insert a packing, but if the packing _becomes large and the flange part is large, it will be difficult to tighten uniformly and the price will be _expensive . There are also disadvantages such as the length in the direction being uneven, and
It is possible to cover the periphery of the flanges with a cap material, but it would be extremely large and
If the outer shape of the flange is not just a straight line or a circle, but a polygonal line, which is relatively complicated, the price of the cap material will be extremely high, and its installation will be troublesome. Alternatively, simply filling and applying a sealant between the flanges would cause the sealant to deteriorate early and have the drawback of not being able to ensure watertightness.However, this invention solves all of these problems and makes it easier to seal the cap material and packing material. It has the great advantage of being able to perform watertight construction easily and quickly with just two liquids without using any water, and can be constructed at low cost.

Furthermore, by making it two-component, by performing the steps in this order, it is possible to check whether the viscous liquid sealant 8 is filled before applying the highly viscous liquid sealant 9. It also has the advantage of ensuring watertight construction.
