Description

[Detailed Description of the Invention] The present invention relates to a roof structure for a prefabricated house that is constructed facing an existing wall.

In this type of prefabricated house, for example, a pillar is erected facing the wall of an existing house, and a beam is extended from the upper end of the pillar so that its tip is close to the wall. It is known that a roof plate is laid on top of the roof, and the space surrounded by the roof plate, the pillars, and the wall surface can be used as a storeroom, a passageway, or the like.

However, in a lever type prefabricated house, it is desirable to minimize the gap between the tip of the roof and the wall to prevent rainwater from entering. It is difficult to adjust the gap between the roof and the wall by selecting the position of the pillar, since it is not always possible to install the pillar at the desired position depending on the presence or absence of obstacles such as fences.

Therefore, we recently installed a beam by bolting the tip to the tip of the base beam.
A beam has been developed in which the length of the beam can be adjusted by connecting it with a nut and changing the connection position by selecting the bolt hole.

However, with this type of system, the length of the beam can only be changed stepwise at a predetermined pitch, so it has the disadvantage that it is not possible to finely adjust the gap between the roof and the wall.

In addition, although a structure to improve the above-mentioned drawback may be achieved by forming countless bolt holes in the beam, for example, there is a drawback that the strength of the beam itself becomes weak.

The present invention was developed with attention to this situation.In a structure having a beam whose length can be adjusted, a fascia that hides the edge of the wall side of the roof plate is placed at the tip of the beam, and its fixed position is fixed. The purpose of the present invention is to provide a roof structure for a prefabricated house in which the gap between the roof and the wall surface can be finely adjusted over a relatively wide range by installing the beam so that it can be adjusted in the same direction as the expansion and contraction direction of the beam. .

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

In the figure, 1 is a pillar.

The pillars 1 are rectangular pipe-shaped pillars erected facing the existing wall surface 2, and a plurality of pillars are arranged in a straight line.

Reference numeral 3 denotes a beam extending from the upper end of each company 1 in the direction of the wall surface 2.

The beam 3 includes a rectangular pipe-shaped base beam 3a that is fixed to the upper end of the column 1 via a dogleg-shaped bracket 4 with a fastener such as a bolt or nut, and a longitudinal direction on the outer periphery of the tip of the base beam 3a. The distal end portion 3b has a C-shaped cross section and is slidably fitted into the base end beam 3a, and the length can be adjusted in stages by changing the connection position of the distal end portion 3b with respect to the base end beam 3a.

The configuration of the connecting portion between the base end beam 3a and the distal end portion 3b is as follows:
Three bolt holes (not shown) are drilled at a predetermined pitch in the longitudinal direction on both side walls of the tip part 3b, and an appropriate number of bolt holes 5 are made on both side walls of the tip part 3b. are drilled at the same pitch as the bolt holes in the proximal end 3a, and the distal end 3
b to match the desired bolt hole 5 with the bolt hole of the base end 3a, and insert the bolt 6 into the matched bolt hole 5. Insert the nut 7 into the through end of the bolt 6.
It is designed to be screwed together and tightened.

Reference numeral 8 denotes a corrugated roof plate laid on the beam 3, and purlins 9 and 10 are interposed between the roof plate 8 and the beam 3.

The purlin 9 installed at the intermediate position of the beam 3 is a normal one with a hook-shaped roof attachment part on one side edge, but the purlin 10 installed at the base end of the beam 3 A roof plate mounting portion 10b having a hook-shaped cross section is provided protrudingly from one side edge of the substrate 10a fixed to the upper surface of the end portion, and a bridge portion 10C having a concave cross-section is integrally formed on the other side edge. A fascia part 10d having an inverted concave cross section is integrally formed at the tip edge of the bridge part 10C, and the end edge of the roof board 8 on the column 1 side is covered with the fascia part 10d of the main building 10. I try to hide it.

Reference numeral 11 denotes a fascia that hides the edge of the roof board 8 on the wall surface 2 side.

The fascia 11 has a front piece 11b with an inverted concave cross section formed on one side edge of a base plate 11a, and a plate-shaped rear piece 11C on the other side edge.
It is mounted on the tip of the beam 3 so that its fixing position can be adjusted in the same direction as the direction of expansion and contraction of the beam 3.

The structure for this is that a reinforcing member 12 having a U-shaped cross section is housed and fixed in an opening at the tip of a beam 3, a bolt hole 13 is bored in the upper surface of this reinforcing member 12, and a nut 14 is inserted in the back side of this bolt hole 13. be held in place by welding, caulking, etc.

Further, long holes 15 elongated in the longitudinal direction of the beam 3 are bored in the base plate 11 a of the fascia 11 in correspondence with the bolt holes 13 .

Bolts 16 passed through these elongated holes 15 and bolt holes 13 are screwed into the nuts 14 to tighten and fix the fascia 11 onto the beam 3.

Note that the distance between the leading edge of the front piece 11b and the leading edge of the rear piece 11c of the fascia 11 is set smaller than the thickness dimension H of the corrugated roof plate 8, and the leading edge of the roof plate 8 is It is inserted and held between the front piece 11b and the rear piece 11C by utilizing elastic deformation.

As a result, the leading edge of the roof plate 8 can be fixed to the beam 3 without using a special purlin.

In addition, the fascia 11 and the main buildings 9, 10 are divided into unit length members corresponding to the erected spacing of the pillars 1, and these unit length members are connected on the intermediate beam 3,
By adding or deleting unit length members such as the pillars 1, beams 3, fascias 11, and purlins 9 and 10, the number of plants can be increased or decreased as appropriate.

The connections between the main buildings 10 are as shown in FIG.
The connecting fitting 17 and the connecting end of the purlin 10 are bolted to the screw holes 18 and 18 provided on the upper surface of the beam 3. I have to.

28 is a bolt hole for bolting the bridge portion 10C of the main building 10 to the connecting fitting 17, and 29 is a bolt hole for bolting the fascia portion 10d to the connecting fitting 17.

The bolt holes 29 at the non-connecting end of the main building 10 are used to attach a gable (not shown) covering the outer surface of the beam 3.

The gable consists of a channel-shaped base member attached to the beam 3 and the purlin 10, and a tip member slidably inserted into the tip of the base member, and this tip member is connected to the fascia. It is bolted to the bolt hole 13 through a long hole similar to the long hole 15 of 11.

Further, the bolt hole 28 at the non-connecting end of the main building 10 is used as an outlet for the rainwater guiding side chain.

Reference numeral 19 denotes an auxiliary column erected below each beam 3 toward the middle position of the beam 3. Between this auxiliary column 19 and the column 1, there is a U-shaped storage space 20 surrounded on three sides in plan view. is forming.

21 is a shelf board that divides the storage space 20 into upper and lower sections.

The shelf board 21 is supported at the front by shelf locking crosspieces 25 . . . and by the bent edge 26 of the panel 22 at the rear.

22. 23 is a back panel covering the back of the storage space 20;
Reference numeral 4 denotes a side panel that covers the side surface of the storage space 20, and a door or the like may be provided between the auxiliary pillars 19, if necessary.

Further, the entire side surface between the pillar 1 and the wall surface 2 can be constructed of a door and a wall.

With such a configuration, the fixing position of the fascia 11 can be adjusted in the direction of expansion and contraction of the beam 3 by tightening and loosening the bolts 16.

Therefore, by making a rough adjustment by adjusting the expansion and contraction of the beam 3, and then finely adjusting the fixing position of the fascia 11, the gap C between the roof and the wall surface 2 can be adjusted to the position where the pillar 1 stands. Regardless of the situation, the desired value can always be set accurately, and has the excellent effect of eliminating the need for cutting and shortening the beams at all on site.

Note that the prefabricated house is of course not limited to a storeroom, and various changes can be made without departing from the spirit of the present invention.

Furthermore, it goes without saying that the means for adjusting the fixing position of the fascia is not limited to the above-described method.For example, contrary to the above embodiment, circular bolt holes may be provided on the fascia side. A long hole may be provided on the side.
