Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a method of assembling an eave in a house unit.

(Prior Art) A construction method in which a box-shaped house unit is manufactured in a factory and a plurality of these house units are installed at a construction site to assemble a house has become popular. In this construction method,
In order to reduce construction costs, it is necessary to improve the degree of completion at the factory and reduce the work at the construction site as much as possible.

From the above point of view, eaves may be attached to house units in advance at a factory. However, in this case, the following problem occurred. That is, when transporting a house unit from a factory to a construction site, the size of the house unit is limited to the range that can be transported. For example, when a house unit is transported by truck or the like, the width is restricted by transportation regulations and cannot be made wider than this width. In a house unit with an eaves as described above, if the overall width including the eaves and the house unit is to be kept within the above-mentioned width limit, the width of the house unit itself must be narrowed.

In order to solve the above problems, a method has been developed in which the eaves are folded during transport and assembled so that they extend out to the sides of the house unit during construction.

In Utility Model Application No. 52-34816, an eave surface material is attached to a pantograph-shaped telescoping mechanism, and during transportation the telescoping mechanism is contracted to bring the eave surface material close to the side of the house unit, and during construction the telescoping mechanism is extended to extend the eave surface material. The materials are kept away from the sides of the house unit. However, with this method, the eave ceiling material must be attached after the telescoping mechanism has been extended at the construction site, resulting in poor workability at the construction site. Moreover, the above-mentioned expansion and contraction mechanism cannot strongly support the weight of the entire eave.

In Utility Model Application No. 53-34818, one end of a plurality of support arms is horizontally rotatably connected to the side surface of a house unit, and the other ends of these support arms are horizontally rotatably connected to the eaves surface material. When transporting, the support arm is tilted toward the house unit to bring the eave surface material close to the side of the house unit. At the construction site, the support arm is horizontally rotated so that the house unit is perpendicular to the side surface, and the eave surface material is moved close to the side of the house unit. are kept away from the housing units. However, in this method, as in the above-mentioned conventional method, the soffit paneling had to be attached at the construction site, and it was not possible to strongly support the weight of the entire eave.

In Utility Model Application Publication No. 56-65037, one end of a first support arm is connected to the house unit so as to be able to rotate in the vertical direction, and a second support arm is attached below the first arm to rotate in the vertical direction. movably connected and hooking the first support arm to the second support arm at the construction site so as to extend from the side of the house unit;
The facing material is attached so as to cover both arms. In this method, the workability was poor because the above-mentioned surface material was attached at the construction site.

(Object of the Invention) The present invention was made based on the above circumstances, and its object is to provide a method for assembling an eaves in a house unit that can reduce work at a construction site and strongly support the weight of the eaves. There is a particular thing.

(Summary of the Invention) The gist of the present invention is to connect one end of a first support arm to an upper side surface of a house unit so as to be rotatable in the vertical direction, and to connect a second support arm to the other end of the first support arm. One end is connected so as to be rotatable in the vertical direction, a soffit panel is attached to the first support arm, an eaves panel is attached to the second support arm, and the first support arm and the second support arm are connected in advance. The first support arm is folded toward the house unit, and when the house is constructed, the first support arm is pulled up in a substantially horizontal direction and the second support arm is connected to the house unit. It's in the assembly method.

(Structure of the Invention) An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. In the figure, 1 is a box-shaped house unit, and wall materials 2 are attached to the sides of the house unit 1, and roofing materials 3 are attached to the top.

A foldable eave 10 is attached to the side surface of the upper end of the house unit 1. More specifically, an arm 11 is fixed to the side surface of the house unit 1. This arm 11 extends vertically, and has arms 12, 1 at its upper and lower ends.
3 are connected to each other so as to be rotatable in the vertical direction. Connection holes 12a and 13a are formed at the other end of each arm 12 and 13, respectively.

A first support arm 1 is provided at the lower end of the arm 11.
One end of 5 is connected to be rotatable in the vertical direction. The first support arm 15 has a soffit panel 16
is installed. One end of a second support arm 17 is connected to the other end of the first support arm 15 so as to be rotatable in the vertical direction. An eaves surface material 18 is attached to the second support arm 17.

The lower end portion of the eave surface material 18 has a bent shape as shown in FIGS. 4 and 5, and includes an end plate portion 18a that covers one end of the second support arm 17, and an end plate portion 18a of this end plate portion 18a. It has an edge 18b with an L-shaped cross section formed at the tip edge.

First support arm 15, second support arm 17
Holes 15a and 17a for inserting temporary fixing pins, which will be described later, are formed in the intermediate part of the second support arm 17, respectively, and holes 15a and 17a for inserting a hook are formed at the end of the second support arm 17.
7b is formed.

Note that the arms 11, 12, 13, 1 mentioned above
The rotatable connections 5 and 17 are made by bolts and nuts. In addition, these arms 11,1
A plurality of arm groups consisting of arms 2, 13, 15, and 17 are installed along the longitudinal direction of the soffit surface material 16 and the eave surface material 18.

The house unit 1 with the eaves 10 described above is manufactured in a factory. When transporting from the factory to the construction site, the eaves 10 are folded. That is, each arm 12, 13, 15, 17 is connected to the house unit 1.
Fold it close to the side of the In this folded state, the first support arm 15 is suspended vertically, and the soffit panel 16 is supported along the side wall 2 of the house unit 1. In addition, the holes 15a of each support arm 15, 17,
By inserting the temporary fixing pin 20 into 17a,
The second support arm 17 is supported in a folded state parallel to the first support arm 15, and the eaves surface material 18
is stacked on the soffit panel 16 via support arms 15 and 17. Further, the arms 12 and 13 are
The housing unit 1 is folded toward the house unit 1 while being locked to the upper end of the support arm 17 and prohibited from rotating.

As described above, since the eaves 10 is transported in a folded state by a truck or the like, the eaves 10 does not protrude to the side of the house unit 1, and the overall width of the house unit 1 and the eaves 10 does not become wide.
This can be done within the limits set by transportation regulations. In other words, it is not necessary to reduce the width of the house unit 1 to keep it within this range.

At the construction site, the eaves 10 is released from its folded state by removing the temporary fixing pins 20, as shown in FIG. Then, the hook 30 of the crane is hooked to the hole 17b of the second support arm 17 and pulled up.
At this time, as the second support arm 17 rises, the second support arm 15 rotates upward. 1st
When the second support arm 15 becomes almost horizontal, the lifting by the crane is stopped and the middle part of the second support arm 17 and the tips of the arms 12 and 13 are connected. That is, one bolt is inserted into the hole 17a formed in the middle part of the second support arm 17 (the hole for inserting the temporary fixing pin described above) and the holes 12a and 13a of the arms 12 and 13, and this bolt and Connect with nuts. Thereby, the eaves 10 can be assembled so as to protrude from the side of the house unit 1.

As mentioned above, since the soffit surface material 16 and the eave surface material 18 are attached to the support arms 15 and 17 in advance at the factory, at the construction site, these surface materials 16 and 18 are not installed, and the arms 12 and 18 are simply attached. ,15,
17. Work efficiency is greatly improved because the parts are simply connected to each other.

In the above assembled state, the five arms 11,
Since 12, 13, 15, and 17 form a truss structure, the weight of the eaves 10 can be strongly supported. Further, in the above-described assembled state, the ends of the support arms 15 and 17 can be covered by the end plate portion 18a and edge portion 18b of the eave surface material 18, as shown in FIG.

Note that the term "eaves" in the present application is a general term for parts that project laterally from the upper part of a house unit, and includes, for example, nose combs, parapets, etc., and the present invention can also be applied to these.

The present invention is not limited to the above embodiments, and various embodiments are possible. For example, the folded state of the eaves is
It may also be held by a rope or the like. Further, there is no restriction on the angle between the eaves surface material and the eave surface material in the assembled state, and it may be approximately 90 degrees, for example.
