Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a lateral connection structure for roof panels.

[Conventional technology]

Conventionally, a connection structure in which roof plates made of fiber-reinforced concrete or the like are laterally joined, as shown in FIGS. 4 and 5, has protrusions provided at the ends of roof plates A and B, and each protrusion A connecting member C made of the same material was molded to cover and fasten.

[The problem that the idea aims to solve]

However, the conventional roof plate connection structure has the problem of creating a difference in air pressure between the front and back surfaces, especially in high-rise buildings, resulting in rain leakage. Conventionally, roof panels were overlapped above the roof panels to create a double or triple structure to prevent rainwater from entering, but this had the disadvantage that a large number of roof panels were required, making it expensive.

Another problem was that there was a limit to the tolerance because sealing materials and caulking materials were relied upon during construction to compensate for the expansion and contraction movement of the roof panels due to temperature changes.

The present invention was devised in view of the above-mentioned problems, and an object of the present invention is to provide a roof board connection structure that prevents rainwater from entering, has large dimensional tolerances in roof board construction, and is easy to construct.

[Means to solve the problem]

In order to solve the above problems, the present invention has constructed the means shown in the following claims.

(1) A bendable plate-like part that has one end fixed to the upper end in the horizontal direction of a square roof board and a locking part provided at the other end, and a square part that is spaced apart from the roof board. One end is fixed to the upper end in the horizontal direction of the roof plate, and the other end is connected to a flexible plate-like part provided with a locking part that engages with the locking part. In the roof board connection structure that covers the space between the roof boards, each locking part has a male part and a female part that engage with each other, and each plate part has a male part and a female part. A roof board connection structure characterized in that the parts face each other, engage with each other, and are connected to each other in a curved W-shape large enough to allow a human hand to fit into the recess.

(2) The roof board connection structure according to claim (1), wherein each of the locking portions and the plate-like portions are made of plastic resin, and the locking portions are hard and the plate-like portions are soft.

[Effect]

[] Since the connected plate-like parts are curved in a W-shape, they can follow the expansion and contraction of the roofing board due to temperature changes, and it is possible to have a large dimensional tolerance when constructing the roofing board.

[] For the same reason as in item 1, the plate-shaped portion can serve as a rain gutter, and can prevent rainwater from entering.

[] Since the connected plate-shaped portions are curved into a W-shape large enough for a human hand to fit into the recessed portions, it is easy to engage the locking portions.

[] Before connecting the shingles, lift each shingle upward to expose the space between the roof shingles. Therefore, by utilizing this spaced portion, the roof plate can be easily fixed to the support member.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

This embodiment is applied to a horizontal connection structure between rectangular fiber-reinforced concrete roof panels 1 and 2. FIG. 1 is a sectional view showing the connection structure of the roof panels, and FIG. FIG. 3 is an enlarged view of the locking portion in FIG.

The connection structure of this embodiment is composed of a pair of plate-shaped parts 3 and 4 that are curved in a U-shape and have locking parts 5 and 6 attached to one end.
The base ends 3a, 4a of the roof plates 1, 4a are spaced apart from each other.
It is fixed to the roof panels 1 and 2 while being embedded in the upper end of the roof panels 2.

Each locking portion 5, 6 is formed with a male portion and a female portion, respectively, and the male portion and female portion engage with each other to integrally connect the plate-like portions 3, 4.

Each of the plate-shaped parts 3, 4 and the locking parts 5, 6 are made of flexible plastic resin, but by adjusting the amount of hardening agent mixed into the resin, the locking parts 5 and 6 have hardness, and plate-like parts 3 and 4 have soft hardness and are formed to be flexible.

Moreover, when each plate-like part 3, 4 is curved into a U-shape,
The recess width dimension b is set so that the operator's hand can fit into the curved recess 12.

It is convenient to attach the plate parts 3 and 4 to the roof panels 1 and 2 in the factory when the roof panels 1 and 2 are being manufactured, and to bend the plate parts 3 and 4 as described above. If the width dimension b has already been determined, this may be done in the factory, or if the width dimension is undetermined or inconsistent, it may be carried out at the roof shingle construction site.

Next, the handling procedure and operation of the connection structure of this embodiment will be explained. When attaching the roof shingles transported to the construction site to the support members of the roof structure, the third
As shown in the figure, the plate-shaped parts 3 and 4 that have already been attached to the respective roof panels 1 and 2 are lifted upward.
By this lifting operation, the space a between the roof panels 1 and 2 is opened, so using this space a, the mounting bolts 10 and 10 of each roof panel are attached to the support member 1.
Tighten to 1.

Next, bend the plate-shaped parts 3 and 4 lifted upward so that the male and female parts of the locking parts 4 and 5 face each other,
Here, when the two are engaged, the plate-like parts 3 and 4 are
They are connected to each other in a bent shape. At this time, since the operator's hand enters the W-shaped recess 12, the engagement work is easy. In addition, since the plate-shaped portion is curved in a W-shape, it can function as a rain gutter for rainwater that has entered, and can also accommodate the expansion and contraction of the roof panels 1 and 2 due to temperature changes. .

In the case of the fiber-reinforced concrete roof plate of this embodiment, the upper part is usually covered with a metal roofing material such as a copper plate, so the plate parts 3 and 4 have a double waterproof structure together with the metal roofing material. This will constitute the following. Furthermore, plastic resin has the disadvantage of being sensitive to ultraviolet rays, but as mentioned above, it can be hidden under copper plates, etc., so its service life is extended.

Further, in this embodiment, the structure of the locking portion is in the shape of a horizontal arrow, but various other structures may be adopted.

In the above embodiment, the locking portion was provided continuously in the vertical direction of the roof plate, but it may be provided partially, and the roof plate may be made of a material having a certain thickness instead of being made of fiber-filled concrete. It can also be made from other materials if available.

[Effect of idea]

As explained above, according to the roof board connection structure of the present invention, construction can be carried out by simply inserting the locking parts together by hand, and it also follows the expansion and contraction of the roof board due to temperature changes. This allows for large dimensional tolerances during construction. Further, since the W-shaped plate portion acts as a rain gutter to prevent rainwater from entering, excellent effects such as preventing rainwater from entering and facilitating the installation work of the roof board can be achieved.
