Description

94276 WALL STRUCTURE AND A BUILDING SYSTEM USING IT 5 The present invention relates to a wall structure according to the preamble of claim 1. The application also concerns a building system using a wall structure *.

In the construction of wooden and log houses, 10 trees / logs have traditionally been used, which are obtained from trees with a diameter of more than 15 cm. Such traditional construction is relatively expensive and always requires both heavy timber and construction equipment.

The object of the present invention is to provide a solution in which buildings, such as dwellings, can be produced quickly and cheaply using small wood, such as is commonly used as pulpwood in the pulp and paper industry, and which may remain in the forest in connection with the top.

20

The invention is based on the idea in which modules of standard dimensions formed of small wood are formed into modules, using which various buildings can be constructed simply.

25

The invention is characterized by what is stated in the claims below.

The solution according to the invention has numerous significant advantages. 30 The solution can be used to produce homes quickly and cheaply, using local materials and simple work techniques. The solution according to the invention is particularly useful. in residential activities that rapidly require large numbers of dwellings: 1 which require certain basic characteristics but not a high level or a long service life. Such targets include, for example, the settlement of refugees or new rural settlements caused by land reforms. In addition, applications can be e.g. sheds, fishing and hunting lodges and holiday homes.

The invention is described below with reference to the accompanying drawing, in which

Figure 1 shows a partial section of a wall-5 kennel according to the invention seen from above,

Fig. 2 shows a building block used in a wall structure, Fig. 3 shows a splice joint and a corner joint from above,

Figure 4 shows the extension of the wall structure and the corner joint on page 15

Figure 5 shows the extension of the wall structure in a perspective view,

Figure 6 shows the corner joint of the wall structure in a perspective view.

The wall structure consists of an outer wall 1 and an inner wall 2 and a space 3 between them, for example for insulation. The outer wall 1 and the inner wall 2 are formed of structural members 4, 25 which are stacked on top of each other. The inner 1 and outer walls 2 are connected by connecting pieces 5 arranged between the superimposed structural pieces 4.

A structural part 4 according to the invention is shown in Fig. 2. A notch 8, 9 is formed in the upper 6 and / or lower edge 7 of the structural part, which is transverse and the entire width of the part. . ·. There are one or more notches in the structure 4 depending on the type of building and the location of the structure 1 in the wall structure. The structural member 4 and the connecting piece 5 are made of wood 35, the diameter of which is preferably in the range of 80-150 mm. In this case, a mini-log according to the invention can be sawn and machined from such small wood, the cross-sectional dimensions h X d of which are advantageous: i ί im m ma:; 3 94276 50 X 50 mm, the length L of the pieces varying according to the application. The width of the notches 8, 9 of the structural member 4 is preferably the width of the connecting piece 5 or the second structural member. The depth of the notch is preferably 1/4 of the height of the structural body, in which case the depth of the notch of the 5 binding pieces is also corresponding. In this case, a sturdy structure is obtained by stacking alternately on top of each other. The dimensionally accurate manufacture of the structural and connecting pieces is important, so that the pieces are preferably planed to have substantially the same cross-section.

The notches in the pieces may be of other depths.

In the extension joint according to Figure 3, the successive structural members 4 are arranged partially overlapping in the longitudinal direction, whereby one or more connecting pieces 5 are preferably arranged at this extension point of the wall structure, where the structural elements doors overlap. In the connecting piece 5, the notches 8, 9 of the structural members correspond to the notches 10, 11, the length of the notch 10, 11 20 of the connecting piece being substantially the width of the two structural members (Fig. 5). The figure also shows an angle joint in which the structural members 4 perpendicular to each other are arranged one on top of the other in layers.

Figure 4 is a side view of the joints of Figure 3.

Fig. 5 shows the structural members 4 of the outer 1 and inner wall 2 set for the splice joint. The notches 8, 9 of the overlapping longitudinally arranged components are placed in position 30, whereby the connecting pieces 5 can be placed in the notches. One fastener 5 can be used in short walls, but in long structures and elsewhere where additional rigidity is required, two fasteners 5 are used in the extension.

Figure 6 shows a corner joint such as is used in the corners of a building using a wall structure according to the invention. In the joint, the structural members 4 perpendicular to each other are placed in the notches of the underlying structural elements in layers.

In a preferred embodiment, the modulus dimension h x d x L of the component is 50 x 50 X 2400 mm. In this case, wood with a diameter of 80 to 150 mm and lengths of 2.5 and 4.9 m and 3.1 m can be used, from which e.g. dimensions 10 and 400 mm required for fasteners and short structural parts 700 mm. Short components are needed e.g. for doors and windows when leaving openings in the wall structure.

The components are used in the preferred example as follows. 15 The foundation of the building is done in the usual way. Bottom beams are placed on top of the supports, which are preferably, for example, 100 x 100 mm wood. The base beams are preferably attached to the supports by a fastening member, such as an anchor bolt. The lowest level of the lower base consists of structural members which are fastened to the base beams 20, for example by nailing. The laying of the wall structure is preferably started from above the lower layer of the lower base. The wall structure is stacked layer by layer, whereby there is a height difference in the starting height of the stacking of the walls to be connected by an angle joint, which is preferably half the height of the structural part. The corner joints and the fasteners used in the joints stiffen the wall structure. The finished wall structure can be tightened, for example, with a vertical wall tightening member, such as a bolt.

When the desired building height is reached, a beam frame is built on the wall-30 en, on which the upper floor is built. The top - bottom cover consists of structural members which are attached. nailing to the frame like the bottom. The necessary insulation is provided on the top floor and walls.

35 A desired roof solution can be arranged in a building according to a building system in the usual way.
