Description

[Detailed description of the invention] The present invention relates to a structure for connecting the upper end of an exterior wall and a ceiling in a building, mainly a prefabricated house equipped with an exterior wall made of lightweight foam concrete.
The purpose of this is to prevent the joining metal fittings etc. at the joining part from being exposed outdoors at all, increasing the fire resistance from the outside, and making it possible to work on the joining from indoors. In other words, the present invention eliminates the need for high scaffolding along the outer wall.In other words, the present invention provides a plurality of recesses with open inner surfaces at predetermined intervals along the upper edge of the outer wall made of lightweight foam concrete. A mounting bracket consisting of an open square cross-sectional steel frame is housed and fixed in the recess with the opening facing indoors, and the side edge of the ceiling body on the top floor of the building is connected to the upper end of the external wall body. is provided with a recess opposite to the recess, and connecting fittings each having an L-shaped cross section are fixed in the recess via their vertical surfaces, and the mounting fitting and the connecting fitting are connected to each other. The present invention provides a structure for connecting the upper end of the outer wall and the ceiling in a building, in which the upper end of the outer wall and the ceiling are connected by bolts while being placed on top. The aim is to provide housing with a further improved appearance.
The gist of the present invention will be explained below based on an example of a joint structure between an outer wall body and a ceiling body shown in the drawings.

Reference numeral 1 denotes an outer wall, which is mainly formed of lightweight foamed concrete P and a steel frame 8, and has an upper edge 2,
A recessed part 4 having an open opening 3 is formed on the inner side 1' (as shown in the second figure), and a mounting bracket 5 having an opening therein is formed.
, a U-shaped locking plate 6, a reinforcing plate 7, and a steel frame 8.
Fixed through part of. The metal fitting 5 consists of an open square-shaped steel frame, has a through hole 9 in its upper surface, and is attached with one opening 10 facing inward. Reference numeral 11 denotes a ceiling body, and a recess 12 is provided on the side edge of the outer wall body facing the recess 4, and a cross section L is formed in the recess 12.
The angle-shaped connecting fitting 13 is fixed by a coach screw 14. This connecting fitting 13
A screw hole 15 is provided in which a nut 15' is fixed, and the screw hole 15 faces the through hole 9 of the mounting fitting 5, and both fittings 5 and 13 are tightened with a bolt 16. In addition, the roof 17 in the figure is formed in a corrugated shape and is supported on the ceiling body 11 by a large number of triangular frame members 17'.
Further, 18 is a roof peripheral component portion that includes a built-in rainwater gutter 19. Note that 20 is a connecting member between the adjacent outer wall bodies 1, 1.

Next, to explain the joining operation of the joint structure of the present invention, the ceiling body 11 is placed on the upper edge of the outer wall body 1, the washer 16' is inserted into the bolt 16,
By inserting the bolt 16 into the through hole 9 from the opening 3 side of the recessed part 4 through the opening 10 of the metal fitting 5, and further screwing into the screw hole 15 and nut 15' of the connecting metal fitting 13, the ceiling can be fixed. The body 11 can be fixed to the outer wall body 1. The tightening work at this time will be carried out from indoors.

In this way, in this invention, the outer wall and the ceiling on the top floor located above are connected by tightening the mounting brackets and the connecting brackets with bolts, and these brackets are completely exposed to the outside. The structure of the present invention can be easily joined as described above, and since this work is carried out indoors, the fire resistance from the outside can be improved. In addition, it is possible to avoid constructing a high scaffold outdoors as in the past, and the appearance is neat and suitable, and the above-mentioned work is easy and maintenance and inspection work is easy through the opening of the mounting bracket, etc. Together, the benefits are enormous.
