As shown in each drawing, each main member forming the skeleton of the frame material for the simple assembly structure is composed of bottom plate portions 1b, 2b and compatible upside plate portions 1'a, 1'a, 2'a, 2'a. It is constructed by using, for example, U-shaped steel having a U-shaped cross section, and has a structure that can be assembled and disassembled by adopting it to a joining portion of steel materials used for a roof top of a house or the like. That is, in the present embodiment, as shown in the first illustration, the pair of main members 1 and 2 having a U-shaped cross-section cut into the same predetermined length have grooves 1a and 2a, respectively.
The other main member 2 is fitted in the groove 1a of the one main member 1 in a state where they are opposed to each other. At both ends of the two main members 1 and 2, compatible upper side plate portions 1'a and 2'a are rotatably supported by bolts 3 and nuts 3a. Notch 1c for regulating main member combination angular position on bottom plate 1b over a distance of l ₁ from the end
Is formed, and the other main member 2 can be rotated about the bolt 3 as a central axis over an angle range of 180 ° or more by the main member combination angular position regulating notch 1c.
Moreover, by rotating the main member 2 by a predetermined angle, the bottom plate portion 2'b of the other main member 2 comes into contact with the end edge portion 1d of the main member combination angular position regulating notch 1c as shown in FIG. The combined angular position of the member 1 and the other main member 2 at the deployed position is restricted.

Also, on the other end side opposite to the pivotal support side of both main members 1 and 2,
A bolt 4 into which a nut 4a is screwed is passed through each groove 1a, 2a and is inserted into the ascending side plate portion 1'a, 1'a, 2'a, 2'a. A pair of angle members 5 and 6 which are bent into a substantially mountain shape as shown in the first and third drawings are arranged between the angle members 3 and 3. These angle members 5 and 6 have the same shape, and the pivotal support portions 5a and 6a located on the bolts 4 and 4 side have a pair of plate piece portions 5'a and 5'a, as shown in the second and third illustrations. 5'a, 6'a, 6'a are formed, and the free end portions 5b, 6b are provided with a bottom plate portion 5'b, 6'b and a compatible upward side plate portion 5 "b, 5" b, 6 ". The cross-sectional shape of b, 6 ″ b is U-shaped. The angle members 5 and 6 have a width that fits the main members 1 and 2, and the pivotal support portions 5a and 6a are formed by bolts 7 and 7 and nuts 7a and 7a on the main members 1 and 2, respectively. Each is pivoted. The length of the pivots 5a and 6a is the same as the bolts 7 and 7.
From the position of the main members 1 and 2 to the ends of the main members 1 and 2, and the pivotal support parts 5a and 6a have
Hole 5c at a pitch l _2, 6c is bored corresponding to the pitch l ₂ between the bolt 7 and the bolt 4 in. Therefore, by rotating the angle members 5 and 6 toward the bolts 4 and 4 around the bolts 7 and 7, respectively, the position of the bolt 4 and the position of the through holes 5c and 6c are matched.

Here, the assembling of the frame member for the simple assembling structure configured as described above will be described.

When rotating in the direction of the arrow in the same figure so as to separate from each other around the center, the end edge 1d of the notch 1c for main member combination angular position regulation of one main member 1 is outside the bottom plate 2b of the other main member 2. Since the bottom surface 2'd contacts and both main members 1 and 2 are assembled and developed by intersecting at a predetermined angle as shown in FIG. 4, they are positioned by tightening the bolt 3.

Next, after removing the bolts 4 and 4 of both the main members 1 and 2, turn the angle members 5 and 6 toward the bolts 4 and 4 around the bolts 7 and 7 to form the through holes 5c and 6c and the bolts. With the through holes of 4 and 4 aligned with each other, as shown in FIG. 4, the bolts 4 and 4 are again inserted into their original positions and the nuts 4a and 4a are tightened to finally assemble. Accordingly, if other aggregates are fitted to the free ends 5b and 6b of the angle members 5 and 6 to join them, a roof structure used for a frame such as a simple assembly house as shown in FIG. The skeleton can be easily formed.

(Effect) As described above, according to the present invention, one end side of a pair of main members each having a predetermined length having a U-shaped cross-section and having groove widths that can be fitted to each other, and their rising side plate portions are bolts and nuts. Rotatably and pivotally supported by the main member, a main member combination angular position regulating notch is formed on the bottom plate of the one main member over a required distance from the pivotal support, and the other end side of the pair of main members is formed. A through hole is formed in each rising side plate portion, and a bolt and a nut are detachably attached to the through hole, and each of the main members between the bolt and a bolt pivotally supporting one end side of the main member. The rising side plate portion has a U-shaped cross-section having a groove width into which the main member can be fitted, and the pivot end portions of a pair of angle members formed by bending in a substantially mountain shape are fixed by bolts and nuts. The angle-shaped tops of the angle members are Each of the main members is pivotally supported in a state of facing the outer side, and further with a pitch corresponding to the pitch between a bolt provided on the other end side of the main member and a bolt pivotally supporting the angle member, Since a through hole for inserting a bolt is provided at the pivot end of each angle member, each main member is first rotated from the state shown in the first figure to the state shown in the fourth figure around the bolt during assembly. By doing so, the outer bottom surface of the bottom plate portion of the other main member is brought into contact with the terminal edge of the notch for main member combination angular position regulation formed on the bottom plate portion of one of the main members, and the bolts are tightened in that state. Each main member can be easily positioned and fixed, and each angle member is also rotated about the bolt from the state shown in the first illustration to the state shown in the fourth, and is attached to the pivot end of each angle member. Mainly through holes for bolt insertion By tightening the rising side plate of the material with bolts, the structure of the roof structure used for house frameworks such as workplaces, construction site offices and greenhouses can be easily welded without using welding machines.
