[Prior art]

 In large buildings such as auditoriums, gymnasiums, warehouses, and factories, part of the roof is opened, and a lighting plate is installed in this opening to form a skylight, and a daylighting device is installed to take in natural light indoors. In order to install a lighting plate in the opening of the roof, support girders are constructed along the periphery of the opening, and support girders of the same shape or other shapes are installed between the rectangular support girders. To form a plurality of rectangular spaces, and a lighting plate is fitted into each space. Alternatively, there is a lighting device in which one lighting plate is fitted in the opening.

Various shapes and structures of support girders are provided, and the support girders are installed on a roof girder or a fixed frame constructed by connecting to the roof girder at the roof opening. It is becoming like this. FIG. 3 shows an example of a conventional support girder material, which is composed of a mounting member A and a connecting member B which are formed by drawing an aluminum material into a long body. The mounting member A has an arbitrary flat surface in the length direction of the rectangular cylinder A1 as a mounting surface, and a lighting plate C made of a meshed glass plate or a synthetic resin plate is provided on both sides in the length direction of the mounting surface. The basic structure is such that a mounting portion A2 is formed and a wall-shaped fixing portion A3 having a height higher than that of the mounting portion A2 is projecting over the entire length in the longitudinal direction between both mounting portions A2. . Incidentally, D in the drawing is a dew receiver formed on the lower surface of the daylighting plate C, which is formed in a gutter shape on both side surfaces of the mounting member A.

The connecting member B is an elongated plate-like body, and has pressing plates B1 on both sides in the length direction, and a recess B2 into which the upper end surface of the fixing portion A3 can be fitted on the lower surface of the central portion in the length direction. Is formed. The connecting member B is disposed so as to face the daylighting plate C mounting surface of the mounting member A, screws the central portion of the connecting member B and the fixed portion A3 of the mounting member A, and mounts the mounting portion. A space for sandwiching the daylighting plate C is formed between A2 and the pressing plate B1.

In order to fix the lighting plate C with the mounting member A and the connecting member B, first, two lighting plates arranged flush with each other on both mounting portions A2 of the mounting member A. Place the end of C through packing E. Next, by placing both pressing plates B1 of the connecting member B over the ends of the daylighting plate C, a packing F is placed between the pressing plate B1 and the daylighting plate C, and the fixing part A3 is fitted into the recess B2. Then, the screw G 1 is inserted from the central portion in the length direction of the connecting member B into the fixed portion A3. A plurality of the screws G are inserted at required intervals along the length direction to integrally connect and fix the mounting member A and the connecting member B.

The daylighting plate C is sandwiched between the mounting portion A2 and the pressing plate B1 via packings E and F, and the screws G are fixed to compress the packings E and F at vertically symmetrical positions. The end portion of the daylighting plate C 1 is strongly fixed by the interaction between the elastic elasticity of F and the metal elasticity of the pressing plate B1. In addition, H in the figure is a caulking material for the rain warding treatment.

[Problems to be solved by the device]

 In the above-mentioned conventional supporting girder member, since the connecting member B is fixed to the mounting member A by using the screw G, the head of the screw G is protruded above the connecting member B, and a plurality of screws are used. Since the screw G of No. 2 is used, it looks bad as a whole. Further, when the screw G is stopped, the tightening force varies depending on the construction worker because the tightening is loose or strong, and the clamping pressure of the daylighting plate C cannot be made constant. Moreover, since the screws G are inserted one by one, the overall work efficiency is poor.

In view of various problems of the above-mentioned conventional supporting girder material, the present invention makes it possible to easily assemble the mounting member and the connecting member without using screws, and shorten the working time. It is intended to provide a supporting girder material capable of sandwiching and fixing a daylighting plate.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of the supporting girder material of the present invention. In the figure, reference numeral 1 is a mounting member and 2 is a connecting member, both of which are formed into a long body by drawing an aluminum material. Is the same as the conventional supporting girder material. Further, the mounting member 1 has a mounting surface on an arbitrary flat surface in the lengthwise direction of the rectangular cylindrical body 3, and both sides of the mounting surface in the longitudinal direction serve as mounting portions 4 of a daylighting plate which will be described later. A wall-shaped fixing portion 5 higher than the mounting portion 4 may be formed between the mounting portions 4 over the entire length, like the conventional mounting member. Further, the connecting member 2 is also a plate-like body having pressing plates 6 on both sides in the length direction, which is similar to the conventional connecting member.

In the present invention, the connecting plate 7 is continuously provided in the horizontal direction along the lengthwise direction at the upper end of the fixing portion 5 to form the connecting space 8 having the side face open in the lengthwise direction and the connecting member 2 of the connecting member 2. The lower surface is characterized in that a connecting plate 9 is continuously provided in a direction opposite to the connecting plate 7 to form a connecting space 10 having an opening on a side surface. The connecting plate 7 is connected to the inside of the connecting space 10 and to the connecting space 10. The plate 9 can be closely fitted in the connection space 8. In the figure, reference numeral 11 is a known lighting plate, and 12 is a dew condensation receiver formed on both sides of the mounting member 1.

Next, a case where a daylighting plate is attached using the supporting girder material having the above configuration will be described. As shown in FIG. 2, the end portions of the two daylighting plates 11 on both sides of the mounting member 1 are mounted on the mounting portion 4 via the packing 13, respectively. After that, when the connecting plate 9 of the connecting member 2 is inserted into the connecting space 8 on the mounting member 1 side from the side, the connecting plate 7 simultaneously enters the connecting space 10 on the connecting member 2 side, and the connecting spaces 8, 10 By closely inserting the connecting plates 7 and 9 into the inside, the placing member 1 and the connecting member 2 are connected in parallel vertically.

In this state, the packing 14 may be press-fitted between the daylighting plate 11 and the pressing plate 6, and the daylighting plate 11 is mounted by the mutual action of the elasticity of the upper and lower packings 13 and 14 and the metal elasticity of the pressing plate 6. It will be firmly clamped and fixed between the placing portion 4 of the placing member 1 and the pressing plate 6 of the connecting member 2.
