There is a method of wall construction (patent LV 14137, 22.10.2008 g, IPC E04B 1/26; E04B 1/38; E04B 2/04) of insulating and carrying a wooden beam with double walls, where wooden beams with double walls connected with the adjacent wooden boards with double walls and in which the rows of wooden bars with double walls stacked on top of each other and/or alternating with each other, with the joined wooden beams with double walls are connected by longitudinal groove walls and/or connective castles, where the rods, the ends of which are screwed and fixed in the Foundation of the building, are vertically and pass through the wooden bars, mainly through the transverse wall.
A disadvantage of the known technical solutions is the complexity, high cost, the unsolved problem of the elimination of cold bridges and optimal breathability.
Ass is whose present invention is to provide a method for constructing load bearing walls based on the cellular beam with triple walls, characterized by integrity, ecological, conservation of heat, the optimal permeability, durability, reduction of construction time and cost of manufacturing and installation.
The technical result is achieved in that the method of construction bearing wall of the insulating wooden cell bars includes connecting wooden cellular beams with adjacent wooden boards, where wooden beams stacked on top of each other and connected along the length of the through openings in the longitudinal walls, and the mounting height is carried out by means of vertical tie-rods installed in the basement of the building and passing through the wooden cross wall bars, the connection along the length of the wooden cell boards consisting of three wooden walls and perpendicular thereto clamps with a drilled center holes, perform the installation and bonding dowels in the end notches of the longitudinal walls and the gusset of wooden beams is carried out by the installation portion of one end of the beam is equal to the width of the beam formed by the outer to the middle lamella, perpendicular cut in the groove of the other beam at some distance from its end, and after the construction of the first and subsequent floors produce a vertical compressor injection heater of acobat is.
The method is as follows. For the construction of load-bearing wall using cellular beams presented on the drawings:
figure 1 - fragment beams (top view);
figure 2 - view of the cross section of the slats;
figure 3 - General view of the beam with cavities filled with cellulose;
4 is a General view of the beam with cavities filled with cellulose wool, with the front wall;
6 is a connection along the length of the hollow cell bars.
Cellular beams are three parallel spaced the same distance apart slats, two external 1 and medium 2, United transversely spaced wooden clamps 3 by connecting dovetail 4 glueless way, and the tabs are staggered, and each lamella in the upper part has a "thorn" 5 and in the lower part of the groove 6 to implement sportowego connection cell bars height and the slits 7 in the end parts to the implementation of the keyway bars in length with pins 8 and sealant.
The latches 3 - wooden beams, with a thickness greater than the thickness of the lamellae, more than 1.5 times.
The 3 tabs in the lower part have the compensation of the slot to prevent the occurrence of cracks and deformation (not shown).
The location of the latches 3 in a checkerboard pattern between the blades 1 and 2 eliminates cold bridges.
Between PA is allelic slats 1 and 2 and pin 3 are formed honeycomb - cavities that are filled with cellulose wool insulation 11.
The thickness of the lamellae and the total thickness of the cellular beam is selected so that when used as a filler ecowool the permeability of the cellular beam becomes equal to the vapor of solid wood.
The ratio n of the thickness of the slats of a wooden beam and the distance between them is determined by the formula n=d1:d2, where d1 is the coefficient of permeability ecowool, and d2 is the coefficient of permeability of selected wood species.
For example, pine trees across the grain:
d2=0.05 Mg/(m*h*PA), d1=0.3 Mg/(m*h*PA), and thus n=5, i.e. when the thickness of the pine slats 30 mm thick layer of wool in the cell cavity is equal to 150 mm, i.e. the ratio of the thicknesses of the blades and the distance between them is n=1:5.
In order to achieve this ratio is to obtain a homogeneous permeability of wall construction that, in accordance with SNIP (II_3_79, paragraph 6.4), eliminates the use of additional vapor barrier and excessive accumulation of moisture inside the structure in the winter.
The density of wool not less than 65 kg/m3that eliminates the settling of the insulation over time.
The length of the cellular beam from 0.5 m to 5.90 m
The outer lamella treated brashirovaniya to emphasize the figure of the wood and to reduce the cost of n is the surface coloration as stitched wood does not require any additional treatment prior to staining.
Cellular beam with triple walls has good vapour permeability. The thickness of the layer of wood and a layer of insulation is calculated on the basis of their permeability.
For example, when used as insulation ecowool wall, representing a "layer cake": tree "(3 cm)+heater(15 cm)+wood(3 cm)+heater(15 cm)+wood (3 cm)" skips pairs, or "breathing", as a single tree.
Properties water vapor permeability of 3 cm of the tree is equal to 15 cm of insulation.
The permeability ecowool 0.3 mg/(m*h*PA).
The permeability of pine and spruce across the grain 0.05 mg/(m*h*PA).
Cellular beams may have the end portion 9 for forming corner joints of the building. With decorative edge of the end face is made for the production by gluing the end brachiomonas slats and external brasiliani lamellas 1, cut on the inner side at an angle of 45 degrees. Thereby is achieved as aesthetics and precision when assembling the corner joints of the building.
The method of construction bearing wall is as follows. The method of construction bearing wall is illustrated in the drawings:
5 is a diagram of the gusset;
6 is a connection along the length of the hollow cell bars;
Fig.7 - angular connection is s constructed of load-bearing walls.
Prepare pile Foundation. Set screw pile Foundation 12. The space under the ground covered with clay. Fastening the first wreath to the platform base with clamping bars and metal vertical tie-rods 14.
Set the locking bars, drill into place 3 holes make mounting in tying the timber vertical galvanized metal tie-rods 14. For fastening tie-rods drilled a hole in the ground base through the latch.
Horizontal laying the first wreath is made by stringing on couplers 14 and by fastening to the platform base through the locking bars.
In subsequent rows of the tabs should be the same, forming a vertical connection.
For the formation of cellular beams along the length of the two beams in one crown he puts to each other in length. In each of them at the ends of the adjunction made the slits 7 (depth of 2 cm, a width of 10 mm). The slot 7 is treated with silicone sealant, and it is inserted dried wood key 8 in the form of a parallelepiped 185 mm*9 mm*40 mm
The purpose of this seal is to exclude the ingress of moisture and wind in the joint. The next crown fits "overlap" (connection length is mandatory offset) on 40-50 cm and is associated with upper and lower through the slight pressure from the beginning of metal couplers 14 (rods) through the holes in the clamps. The rod is made with a diameter of 8 mm, a height of 1 m Through each meter rods are joined by metal couplings. Vertical metal screed 14 pass through the wall in each retainer 3.
The gusset wall is assembled at the construction site of two fragments of cellular beams.
One fragment end 9 with a closed decorative edge. With decorative edge of the end face is made for the production by gluing the end brachiomonas slats and external brasiliani lamellas 1, cut on the inner side at an angle of 45 degrees (pos.10). Thereby is achieved as aesthetics and precision when assembling the corner joints of the building. At some distance from the end of the first piece is cut a groove on the inner slats and to the middle lamella width equal to the sum of the thicknesses of the inner 1, medium 2 slats and the cavity between them for installation of the second fragment.
The second segment, perpendicular, is set in the first through the excision of part of the beam from the inner lamella to medium.
Then all perpendicular joints are strengthened by screws 15.
The insulation is installed, forcing the cellulose in the cell cavity beam.
The use of wool, containing in its composition such as cellulose, flame retardants and antiseptics, can achieve high thermal insulation, and in addition, high ohnest is nosti design. Cellulose is hygroscopic, readily absorbing moisture from the external environment and easily giving it back, which provides a high permeability cell beam containing as filler ecowool. The presence ecowool antiseptic additives improves the biological properties of the product, namely resistance to rodents, fungi, and insects.
Significant differences of the proposed method is:
- increasing tightness, thermal insulation properties and achieving a homogeneous permeability constructed wall;
- use keys when connecting to the length ensures the exclusion of moisture and wind in the connecting seam;
- stewardship is achieved by using as a sealer ecowool;
- reducing the time and cost of manufacturing and installation;
- the ability to build a solid, reliable, durable wooden houses;
- ensuring the possibility of constructing a building without the use of heavy construction equipment;
- does not require fine finish, because the outer lamella treated brashirovaniya to emphasize the figure of the wood.
- provision of high structural strength.
Homogeneous vapor permeability is provided by the calculation select the width of the cellular beams, the ratio of the thickness of the lamella and retainers and a given density ecowool in combs, that allows for the presence of excess moisture in the room to absorb it into himself, as if her failure to pay.
Build load-bearing walls can be done in two working because of the ease of Assembly and ease of design elements in a short time and at any time of the year.
