Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention comprises a wall body formed by butt-joining wall panels in their surface directions, and a gable wall of an attic that is joined to the upper end of this wall body. This relates to the joint structure with the attic panel.

``Conventional technology'' Traditionally, in wooden prefabricated houses, walls, floors,
A method of constructing a roof or the like using a wooden panel consisting of a frame and a panel attached to at least one side of the frame has been implemented.

Figure 4 shows a conventional example of constructing a gable wall for a house with a gable roof using this construction method. A wall W formed by butting and joining a plurality of wall panels 1 in the surface direction, and a triangular roof panel 2 that is joined to the upper end of this wall W and forms the gable wall of the attic. It is constituted as a subject.

The wall panels 1 are formed in two different sizes to match the height of the gable wall, and on top of each wall panel 1 is a roof panel formed in a triangular shape. 2 have been adjudicated.

Note that a cassette plate 3 is used to join the wall panel 1 and the roof panel 2, and the cassette plate 3 is an elongated rectangular flat steel plate with nail holes for nailing in several places. 4, 4, etc. are provided, and by pasting and nailing them from the surface sides of the wall panel 1 and the shed cut panel 2, the two are firmly joined. .

By the way, with conventional construction techniques, when constructing this type of gable wall, a method is generally adopted in which the wall panels and the roof panels are manufactured separately and then joined together on site. However, in recent years, with the progress of industrialization of prefabricated houses, walls W etc. are made into units by integrating multiple wooden panels in advance at the factory, and these are transported to the site and used for flooring. Second, construction methods that can be avoided are increasingly being adopted.

"Problem to be Solved by the Invention" However, in such a construction technique that unitizes wall panels, it is preferable to use wall panels with the same height according to the unitization of wall panels and CAD. In that case, the end wall of a gable roof would have to be assembled by dividing the rectangular wall panels of different heights into two layers, upper and lower.To achieve this, the following issues were solved. Must.

In other words, wall panels with a rectangular outline are configured in 1 lower 2 tiers,
In a structure in which a roof panel is further assembled on top of the roof panel, the number of joining points for the panels increases, so the conventional panel joining technique using a cassette plate is not sufficient in terms of strength.

The present invention has been made in view of the above-mentioned problems, and includes:
The object of the present invention is to provide a panel joining structure in a gable wall that improves the joining strength between wall panels in response to three-tier stacking of wall panels.

``Means for Solving the Problems'' In order to achieve the above object, the present invention provides a wall panel with the same height dimension, which is formed by attaching face plates to both sides of a frame assembled in a rectangular outline, in the direction of its surface. This is a joint structure of a wall formed by butt-joining the walls, and an attic panel that is joined to the upper end of this wall and constitutes the gable wall of the attic, the upper frame of the wall panel and the roof panel being joined to each other. A U-shaped joint hardware that crosses these frames and fixes them is fitted from the inside of the wall between the bottom frame and the joint hardware between the bottom frame and the bottom frame. The cassette plate is fixed by a connecting bolt passing through the wall panel and the roof panel, and the cassette plate is nailed to the inside of the wall body so as to cross the wall panel and the roof panel.

"Function" When achieving the joint structure according to the present invention, a U-shape is provided between the lower frame of the wall panel and the lower frame of the attic panel to cross these frames and fix these frames. 111 in shape
1) Insert the metal fittings into the wall from the inside, fix the metal fittings with connecting bolts that pass through the upper frame and the lower frame, and then attach the cassette plate from the inside of the wall panel. Just nail them into each panel.

In addition to integrating the cassette plate itself with the panel by nailing the wall panel and the attic panel, the frames are fixed to each other from the inside of the wall using metal fittings, so the panel can be attached by external force from the outside of the wall. Even if the joint surface of the panel is subjected to a force in the direction of separation using the joint on the outside of the panel as a fulcrum,
The fastening by the joining hardware makes it possible to counteract said forces acting on the joining surfaces of the panels.

"Embodiment" An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In these figures +i, reference numeral 10 is a wall panel that constitutes the first floor part of the gable wall, and reference numeral 11 is an attic panel that is joined on top of this wall panel 10 and constitutes the wall of the attic. The invention includes the wall panel 10 and the /11 attic panel 1.
The main feature is the bonding structure with 1.

First, the wall panel 10 is explained. This is made by attaching face plates lOb to both sides of a frame 10a set in a rectangular outline, and the wall panels 10 of the same height are butted and joined in the direction of the surface. By doing so, the wall W on the first floor
It constitutes.

The attic panel 11 is made up of a /l'1 type wall panel 12, which is formed by attaching face plates 12b to both sides of a frame 12a assembled into a rectangular outline like the wall panel 10, and this small wall panel 12. 1- and triangular roof panels 13 joined on the left and right sides. Note that the roof panel 13 is a frame body 13 framed in a triangular shape.
In the embodiment, the attic panel is made up of two types of panels: a right-angled triangular panel and a panel forming the apex of the roof. ing.

Next, the joint structure between the wall panel 10 that constitutes the wall W of the first floor portion and the attic panel 11 will be explained.

According to the present invention, the joining structure between the γ panel 10 and the attic panel 11 is also basically integrated from the inside of the wall using gusset plays 1-17.

However, in the present invention, a U-shaped joining metal fitting 1 is used to fix the frames of the panels joined vertically by straddling the frames.
5 is fitted from the inside of the wall W by penetrating the face plate of the wall W, and the joining hardware 15 is fixed by a connecting bolt 16 passing through the upper and lower frames of the panel. It is something to do.

The joining hardware 15 is formed by, for example, bending a flat steel into a U-shape, and more specifically includes a main body 15a with a nail hole 15d nailed into the inner surface of the panel, and a main body 15a with a nail hole 15d nailed into the inner surface of the panel. It is mainly composed of flange portions 15b provided vertically to the main body portion 15a above and below the portion 15a.

The distance between the upper and lower flange portions] and 5b is set to such a size that the upper frame and lower frame of the panel joined below 1 are sandwiched therebetween, and the distance between the flange portions Insertion holes 15c through which the connecting bolts 16 are passed are formed in each of the holes 15b.

The cassette plate 17 is made of a rectangular steel plate formed long along the joints between the panels.
Along the length direction, a fitting hole 17a is formed to eliminate interference of the joint metal fitting 15, and a plurality of nail holes 17b,
... are provided above and below the cassette plate 17.

Next, the operation of the joining structure according to the present invention will be explained.

As shown in FIG. 1, a wall panel 10 and an attic panel 11
In order to join these, a joining hardware bent in a U-shape is placed between the upper frame of the wall panel 10 and the lower frame of the front and back panels to cross these frames and fix these frames. 15 is fitted into the wall from the inside, and the joining hardware 15 is fixed with a connecting bolt 16 passing through the upper frame and lower frame of the panel and a nut 18 screwed into this connecting bolt,
The cassette plate 17 may be pasted from the inside of the wall panel and nailed to the upper and lower panels, respectively.

In addition, a notch hole 20 is provided in advance in the face plate of the panel to which the joining hardware 15 is attached to eliminate interference with the flange portion 15b of the joining hardware, and an opening for operating the connecting bolt 16 is also provided. Needless to say, when accessing the flange 15b, the flange portion 15b is inserted into the notch hole 20, and the connecting bolt 16 is screwed through the operation opening.

In this joining work, the panels that make up the end wall are butted against each other, the joining hardware 15 is attached via connecting bolts 16 so as to sandwich the frame of the panels, and the cassette plate 17 is nailed from the inside of the wall W. It is a simple task,
In addition, the attachment of the joint hardware is a simple task of just nailing the cassette plate 17 to the wall panel 10.
Since the attic panel 11 and the attic panel 11 can be firmly joined flush with each other, the work can be simplified.

According to the embodiment, the wall panel 10 and the attic panel 11 are each integrated by nailing the cassette plate itself, and in addition, the frames are sandwiched together by the joining metal fittings 15 from the inside of the wall W. Since it is fixed in this state, even if the joining surface of the panel receives a force from an external force from the outside of the wall in a direction in which the joining part on the outside of the panel is used as a fulcrum, this force cannot be resisted by the joining hardware 15. Therefore, there is an advantage that sufficient strength of the joint can be ensured.

It goes without saying that the joining structure of the present invention is not limited to the configuration of the above-mentioned embodiments, and the specific configuration thereof can be changed as appropriate for implementation.

In addition, in the embodiment, the small wall panel 12 and the shed panel 13 constituting the attic panel 11 are
Although the cassette plate and the wall panel 10 are connected by a joining structure similar to that used for joining the wall panel 10, this part can be joined only by nailing the cassette plate as in the conventional art.

"Effects of the Invention" As explained in the following two, according to the present invention, the following excellent effects can be achieved.

(a) For wall panels and attic panels, in addition to integrating the gusset plate with the panel by nailing the gusset plate itself, the frames are fixed to each other from the inside of the wall using joining hardware, so from the outside of the wall Even if the joint surface of the panel is subjected to external force in a direction that separates the panel from the outside joint part as a fulcrum, the joint hardware can resist that force, and as a result, the strength of the joint part is increased. can be secured sufficiently.

(b) As a result of the above, it is possible to provide a panel joint structure in the end wall with high joint strength, and it becomes possible to easily accommodate three-tier stacking of wall panels.
