Description

[Detailed description of the invention] (Subject of invention, field of industrial application) The invention is used in the field of architecture.

The present invention relates to a log cabin type prefabricated house.

(Prior art and its problems) In recent years, processing wood into cylindrical materials has been attracting attention as a way to increase the added value of small and medium-diameter materials such as larch. Cylindrical materials have great utility in parks, field athletic facilities, and other applications. In addition, log cabins, which take advantage of the warmth of wood, are particularly popular, and log cabin villas, lodges, and coffee shops are becoming popular.

However, traditional log cabins had the following problems.

(a) Log cabins built in a pure warehouse structure do not use supports or beams, so they are structurally weak and difficult to obtain construction approval.

(b) Cylindrical materials used for wall materials are expensive, and the construction cost per tsubo is higher than that of a general wooden house.

(C) Bolts, bracing, and other reinforcing materials are used in many places to obtain strength, which requires a lot of work and takes a long time to complete.

(d) The interior walls are made of logs and are uneven, making it difficult to live in although it looks good.

etc.

(Objective of the present invention) The purpose of the present invention is to (a) It must have sufficient structural strength.

(b) Construction costs are lower than traditional log cabins.

(c) Simplifying the work process and shortening the period for completion.

(d) It is easy to live in by eliminating unevenness on the inner walls.

The purpose of the present invention is to provide a log cabin type prefabricated house featuring the following features.

(Structure of the Invention) The technical means of the present invention taken to solve the above problems are as follows.

That is, the present invention provides an assembled house with (a) a column having a dovetail groove formed over almost its entire length, and (b) a column having a substantially semicircular cross-sectional shape that fits into the dovetail groove and spans between the columns, and is attached to the inner wall of the house. It is a prefabricated house comprising: and a required number of wall members forming an outer wall.

(Example) The present invention will be explained in more detail based on the example shown in the drawings.

FIG. 1 is a front view, and FIG. 2 is a side view. FIG. 3 is an exploded perspective view.

The symbol H is a prefabricated house. The assembled house H has a foundation 1 and a wall 2
and a roof portion 3.

FIG. 4 is a plan view of the foundation l, and FIG. 5 is a sectional view taken along the line B-B in FIG. 4 showing the construction state of the foundation.

The base 1 is made of four concrete blocks 10a, 10b, 10c, and 10d each having an inverted T-shaped cross section and is connected by a metal fitting 11.
are connected to form a rectangle in plan view. Block 10a
, 10b, 10c, and 10d have a required number of anchor bolts 12 protruding from their upper surfaces. And on the base 1, a rectangular lower base frame 2 on which a wall 2 is erected by an anchor pole 12.
o is attached. Note that the reference numeral 13 is a ventilation opening.

To explain the structure of the foundation, first, a trench 19 of a predetermined size is filled with chestnut stone 18 at the bottom.

On top of the chestnut stone 18, sand 17 is spread so that the base 1 fits snugly, and the base 1 is placed on it. Then, soil is backfilled on top of foundation 1.

FIG. 6 is a perspective view of a connecting portion showing another embodiment of the base 1, and FIG. 7 is an exploded perspective view showing its shape.

The base 1 consists of two blocks 15a and 15b, respectively. The base 16 of one block 15a protrudes, and the mounting base 14 of the other block 15b protrudes. Then, combine the connecting fittings 11 as shown in Fig. 6.
, lla and bolts 11b. This embodiment has the advantage that the connecting portion is less likely to shift than the base l of the embodiment shown in FIG.

Next, the structure of the wall portion 2 will be explained. 8 is a cross-sectional view of the main part taken along the line A-A in FIG. 1, and FIG. 9 is a cross-sectional view of the main part taken along the line C-C in FIG.

In this embodiment, four pillars 21 are erected at the four corners of the lower base frame 20. Although there are no particular limitations on the method of attaching the strut 21, it is desirable that it be resistant to being pulled out, such as by pounding a cork. A required number of wall members 23 are fitted between each support 21, respectively. An upper base frame 20a to which the roof portion 3 is attached is attached to the top of the support column 21.

10 is an enlarged view of section D in FIG. 8, and FIG. 11 is an enlarged view of section E in FIG. 9.

Two dovetail grooves 22 are formed in the side surface of the column 21 in the length direction. The two dovetail grooves 22 are formed at the wall member 23.
This is the position where the two wall members 23 are approximately at right angles when inserted.

The wall member 23 has a substantially semicircular longitudinal section and has tenons 22a formed at both ends to fit into the dovetail grooves 22. A connecting protrusion 24 is formed at the top of the wall member 23 over almost the entire length in the longitudinal direction, and a connecting groove 25 into which the connecting protrusion 24 fits is formed at the bottom. The wall member 23 has its tenon 22a fitted into the dovetail groove 22, and is successively dropped from the top of the support column 21. In addition, an upper surface 27a sandwiching the connecting protrusion 24 in the front and rear,
27b is provided with a step by making the upper surface 27a slightly lower. According to this, when the connecting protrusion 24 is fitted into the connecting groove 25 and the wall members 23 are stacked, the upper surface 27b and the bottom surface 28 of the wall member 23 are in close contact with each other.

Note that the structure of the window 100 is as shown in FIG. First, the short wall members 23a are fitted into the two pillars 21, and the window 101 is formed at the interrupted portion.

Then, a window frame 102 is attached to the window 101, and a sash 103 is further attached to form the window 100.

FIG. 12 is a sectional view showing another embodiment of the wall member 23. In this embodiment, the contact surface 201 of the wall member 23 is
It is formed diagonally upward toward the inside of the body. This has the effect of preventing rain and wind from entering the interior.

FIG. 13 is an enlarged view of section F in FIG. 9.

A groove 29 is formed in the bottom surface 200 of the upper base frame 20a at a position that fits into the connecting protrusion 24 of the wall member 23. When the upper base frame 20a is attached to the support 21, the bottom surface 20a
A gap 202 is provided between the uppermost wall member 23b and the upper surface 27b of the uppermost wall member 23b. This gap 202 is provided to accommodate vertical displacement of the wall member 23 that expands and contracts due to moisture. In this embodiment, the groove portion 29 and the connecting protrusion 24a of the wall member 23b are formed slightly larger. A required number of pressing members 290 such as springs and leaf springs are provided in the groove 29 to press the wall member 23 downward. According to this, even if the wall member 23 is repeatedly expanded and contracted in the vertical direction due to changes in temperature and humidity, no gap will be formed between the contact surfaces 201 of the upper and lower wall members 23.

FIG. 14 is an exploded perspective view showing a method of attaching the upper base frame 20a to the support column 21. The connection method may be any conventional method, but in this embodiment, the roof portions 3 are connected by plugging here and there to prevent them from blowing up easily. Note that the reference numeral 205 is a drain plug.

FIG. 15 is a partially cutaway front view of the roof portion 3.

FIG. 16 is an enlarged sectional view of a part in FIG. 15,
FIG. 17 is an enlarged sectional view of the 5th part, and FIG. 18 is an enlarged sectional view of the 2nd part, showing the method of attaching the roof 30 to the purlin 31. FIG. 19 is an end view of the main part of G--G in FIG. 15, and shows a method for attaching the wall panel 33.

The shape of the roof portion 3 of this embodiment is a bent-back type.

Various methods of constructing the roof portion 3 are possible using conventional techniques. In this embodiment, first, a frame is placed on top of the upper base frame 2Oa attached to the upper part of the wall part 2 using the poles 32, purlins 31, and the like. A groove portion 34 is formed in the hook 32, and a wall panel 33 of a flash structure filled with a heat insulating material is fitted into the groove portion 34. Further, a casement window 110 is attached to the window 111.

Next, a method for attaching the roof 30 to the ridgepole 31 will be explained.

The roof 30 attached to the ridgepole 31 is made up of four panels, and has a flash structure filled with a heat insulating material such as glass wool 105 inside. First, roof 3 on ridgepole 31
0 is installed using a mounting bracket 3 with a cross-sectional shape that matches the angle.
6 with bolts 37 or coach screws 38. Then, the roof 30 is attached to the mounting bracket 36 with bolts 39. Note that the mounting portion 390 of the bolt 39 is formed on the crosspiece 300 of the roof 30 having a flush structure. Then, a roofing material 40 is applied to the roof 30, and cover plates 41 and 42 are attached for preventing rain leakage and reinforcing the roof.

Alternatively, the roof 30 may be created in advance by fixing bolts 39 to the crosspiece 300 and attaching the roofing material 40 and the cover plates 41 and 42, and then assembling the roof 30.

The procedure for assembling the prefabricated house H of this embodiment is shown below.

(1) Installing the foundation 1 in the groove 19 creates a foundation.

(2) Attach the lower base frame 20a to the foundation 1 and erect the support columns 21.

(3) Wall members 23 are dropped from above between the supports 21 to form a wall.

(4) Attach the upper base frame 20a to the support column 21.

(5) Frame the roof section 3 with the ridgepoles 31, ridgepoles 32, etc. on the upper base frame 20a, and fit the wall panels 33 together. (6) Attach the roof 130 to the ridgepoles 31 of the framework.

(7) Roof (past No. 40 on roof 30, cover plate 41.4
Attach 2.

(8) Install windows 100 and 110 and doors.

The assembly is completed.

Note that a mezzanine floor may be built in the prefabricated house H so that the space can be used effectively.

(Effects of the Invention) Since the present invention has the above configuration, the following effects are produced.

(a) Unlike log cabins built in pure warehouse construction, this log cabin uses supports and beams, so it is strong enough.

(b) Since half-cylindrical material is used for the wall material, the material cost is low, and the construction cost is lower than that of conventional log cabins.

(C) Fewer bolts, bolts, and other reinforcing materials are used, simplifying the assembly process and shortening the construction period.

(d) The interior walls have few irregularities and are almost flat, making it easy to live in.

It is Nato.
