The invention relates to the field of construction and can be used not only when laying on solid ground (wall), but also as beams and struts (supports) with variable length required and ordered by project construction under the splice bar-shaped gauge length in the module beams of desired length directly at the construction site.

Known methods of increasing and splicing parts of building structures (A. Shepelev. How to build a farmhouse. M: Rosselchozizdat, 1981, SMS 79...81).

These techniques can be used only for parts of solid section and in raw form for logs-cylinder, requiring adjustments to the desired length by cutting logs and adjusting the length. Details of off-gauge length using the locks can be used as analogue.

The closest analogue of the claimed device can be made of the device, shown at 34, s, A. Shepelev. How to build a farmhouse. M: Rosselchozizdat, 1981. This unit can be taken as a prototype.

The prototype also has disadvantages:

- the impossibility of achieving high-quality drying of timber solid section length without warping and cracking;

- capacity end-to-end with a cylindrical pin can be used only for parts of a continuous slashing the Oia and only for parts, stacked on a solid rigid base (crown), or as a stand not carrying lateral load, and does not allow for joint no gap, respectively, and use it with modern requirements for quality construction.

These disadvantages are not inherent in the stated module Brusova.

The aim of the invention is the creation, by building up without the use of sawing with the fitting and fabrication of the outer end of the locks of any known type, quality dried lightweight and low thermal conductivity of hollow module prosavage off-gauge length, directly on the construction site, the required size and length, parts of a length of hollow beam-rod fitted with a “pin” lock-trihedron installed inside, (void), at one or both ends (the ends), beam-rod, for example beam-rod length equal to one-meter - minimum size used in the construction of houses beam, between the jambs of the Windows.

This goal is achieved by the fact that the module beams with variable length obtained by increasing (splicing) of the beam-rod length, is made hollow and composite, glued from dry lumber (boards) to the required length, starting with a one-meter length, and is equipped with a “pin” lock-trihedron, set the slow inward (void) timber-stud on one or both ends, (the ends), the original timber-rod depending on future conditions of its application. At the same time declared the beams module allows to achieve the following advantages over the prototype:

using the existing technology of drying of sawn timber (planks) eliminates the problem of drying lumber solid section length (six-meter), in which the beam leads, warps and restrictive, which reduces the efficiency of its use, turning a large part of the cross section in a shaving or trimming length;

- splicing timber hollow, provided with a “pin” lock-trihedron ensures the quality of the joint along the edges and its external visual perception using glue and planing;

hollow beam with variable length compared to solid timber section has a low thermal conductivity (heat loss) in the structure and creates a stay;

- weight per meter hollow module prosavage not less than 20% below the mass of the beam solid section;

elements module prosavage off-gauge length - beam length equal to the length of one meter, allows you to use free short lumber and create waste-free production of high quality products.

The proposed module design prosavage shown in figure 1...3. Figure 1 shows a longitudinal view of the junction of the beams module is O. Figure 2 shows a cross-section of the module prosavage “interface” in figure 1. Figure 3 shows the end (end face) of the source element, the beam length is installed inside the “pin” lock-trihedron at one end (the end) and potentially mounted on the other end (the end). Figure 4 shows a view B figure 3. Figure 5 shows a diagram of the cantilever load module prosavage when using it as a beam. Figure 6 shows a cut-In console loaded beams at the joint of figure 5. 7 shows a diagram of a concentrated load applied at the junction module prosavage when using it as a beam. On Fig shows a section of the beam at junction 7.

The beams module consists of a composite hollow beams-rod length 1...n, which are composed of the lateral edges 2, the upper and lower faces 3 and “pins” locks-trekhgrannykh 4 mounted inside the cavity 5 at one or both ends (end faces) of the beam-core 1...n.

In the operation of the module beams of length manifests itself as follows.

When building log cabins of the construction of their walls and walls (partitions) form of six-meter wooden-rod length with application filing and tie-ins with various types of locks and pins, as this raises the need for beam-rod with variable length, not supplied them made the parents.

The proposed module design prosavage effectively solves the problem of not measuring of lengths by continuity of the Assembly process of construction objects without application filing and zapilovki the inset of various known types of locks.

When there is need for the beam-rod with variable length, for example, more than six meters, supplied by the manufacturer, with capacity in one or both sides, right or left, to hollow rod length 1 or “n”equal to one-or six meters and fitted in the cavity 5 for both or one ends (the ends) “pins” locks-trekhgrannykh 4 installed and secured, for example, still in the clamps, zapressovyvajut hollow bars-rods length similar to terminals 1...n, but without the “pins” lock-Tigranian 4 both or one of the ends 6, previously causing the adhesive on the surface of the end faces come into contact and compress the rods-the rods, for example, hydraulic clamps or conventional wedges to ensure the quality of the glue joints. Thus, increasing the beam length, receive module battens required off-gauge length. If the extension beams are supposed to be used as beams, exposure clamps-gluing required. Thus, if the beam is loaded by bending down load “p” is focused and applied in the middle of Alki, put it by the base of the castle-trihedron 4 on the bottom and Vice versa when the load “p” beams on the ends (console). When using glued module prosavage for laying in the crown of the framework exposure clamps bonding is minimal, and the position of the base of the castle-trihedron 4 horizontally at the top or bottom. When ordering a construction project, the manufacturer will supply the whole set of modules beam at the customer's address with marking the place of laying and non crown.

Declared beams module has the following advantages. First, the hollow beams module easier and more convenient in loading, transporting, stacking and migration when using manual labor.

Secondly, the module is placed devoid of internal stresses and moisture, as it is made of dry lumber in comparison with timber, made of whole logs and, as a rule, poorly dried and twisted.

Thirdly, the “pin” lock-trihedron, located in the plane of the greatest tangential stresses module brasavola, allows the latter to use as beams and posts with regard to acting on them loads.

Fourth, thermal conductivity module prosavage times lower than thermal conductivity of a continuous beam that creates economic effect materialstrategy on fuel and comfortable is be in the room.

Fifthly, there is a one hundred percent use of building materials in the construction site of the customer (waste production), since the buildings are of timber is the element module prosavage minimum length equal to the minimum distance between the jambs of the window, up in the conditions of building in the module with variable length required at a specific moment for installation on a specific location of the structure.

The declared module beams with variable length patent satisfies the criterion of “novelty”, as it has significant distinguishing features of the prototype. Meets also patent the criterion of “substantial differences”because the applicants neither patent nor in the technical literature is not detected, the device with the properties characteristic of the claimed device.

The economic effect from the use of this device during construction of timber will be expressed primarily in improving the stabilization of the comfort of living conditions in these objects, as well as in increasing the efficiency of working conditions.

Module beams with variable length, formed by splicing of bars length, characterized in that the bars gauge length is made hollow and a compound having one or both ends of the locks-trekhgrannykh installed inside the I beam, while the basis of the trihedron is located below or above.
