Description

The inventive utility model relates to housing and can be used in the construction of low-rise individual residential buildings.

There are known designs of wooden walls cut down from logs or beams (see the book by V.F. Ivanov “Wooden Structures”, p. 48-49, L., 1956). With a small bulk mass, the necessary strength and low heat conductivity, wood is a good material for walls. Such walls take place mainly in the construction of low-rise residential buildings.

The disadvantage of wooden walls is the considerable complexity of the assembly - disassembling them, due to the design feature of the connections of the corner joints “into the cup” or “into the paw”. For this reason, the rolling of the logs during the assembly of the walls is carried out sequentially, starting with the lower crown and ending with the upper crown.

Also known are the designs of wooden walls made of logs or beams (see V. Minevich “Building Walls”, Science and Life, No. 7, 1990, p. 78-83). The corners of the log walls are traditionally chopped “into a cup” or “into a paw”. The “in the paw” connection is more complex in its construction and requires highly skilled carpenter engaged in the manufacture of this log house.

The disadvantage of such wooden walls is the considerable complexity of both manufacturing them and assembling-disassembling, due to the design feature of the corner joints (ties). Taking into account the peculiarity of the logging technologies, it should be remembered that the log cabins are repeatedly collected, they stand for six months for drying, so that after that they will be rolled out again and finally put back in place.

From the above it follows that the complexity of the assembly-disassembly of the log house has a significant impact on the cost of construction work in the direction of its increase.

Known prefabricated wall block (see the invention of the USSR by auth. St. No. 975957 according to class E04C 1/10 of October 14, 1980), which contains single blocks located one above the other, each of which is connected at the ends by brackets.

The disadvantage of the prefabricated wall block is the unsatisfactory reliability of the brackets, which (reliability) is revealed during the transportation of prefabricated blocks from the place of manufacture to the construction site.

Also known is the connecting structure of wall elements with a stand (see invention RU according to patent No. 2178483 M. class 6 Е04В 1/10, ЕВВ 2/08 of February 17, 1997, the country of priority is Finland). The design consists of logs (beams) stacked on top of one another with the formation of a wall held at the ends using racks with grooves in the cross section in the shape of a dovetail. The groove in the rack is made combined and is a combination of an open groove of a rectangular section with a groove of a dovetail type. The width of the open groove allows you to cover the logs of the wall at some distance from their end with the closing protrusions that hold the wall and due to which the purge of the joint decreases in strong winds.

The disadvantage of connecting the logs with the stand is the complexity of its design, which (complexity) is due to the peculiarity of the groove in the rack and the protrusions of the trapezoidal at the ends of the logs (beams) "in the paw", requiring higher qualification of carpenters and the manufacture of elements of joints (connections) in the factory .

Patent for invention RU No. 2178483 is the closest to the claimed object in terms of technical nature and function.

The objective of the technical solution is to accelerate the assembly and disassembly of the log house and, due to this, reduce the cost of building low-rise individual residential buildings.

The problem is solved in that the known wall building element of logs and beams, stacked on top of each other with a heater between them, held by racks in contact with the ends of the element, connected by means of a spike groove, is composed of at least two logs or beams connected between each other by at least two dovetail-type elements spaced apart from each other, moreover, the spike groove of the upper log (beam) of the building element with the uprights is made “in the paw”, i.e. trapezoidal section, and for the rest of the logs (beams) from the lower to the upper connection "tenon groove" made of rectangular cross section.

The proposed construction of a wall building element with racks allowed to accelerate the construction of a wooden house due to the acceleration of the assembly process and the possibility of using mechanization means, for example, a truck crane.

The connection "spike-groove" of the rack and the ends of the logs of the wall element with rectangular profiles reduces the cost of their manufacture.

The implementation of the trapezoidal connection in the paw at the top of the uprights and ends of the upper log (beam) prevented a possible collapse of the walls and increased the structural rigidity of the log house as a whole.

The following drawings illustrate, as an example, the implementation of a utility model - “Wall building element of logs or beams, confirming the possibility of its industrial use when using the entire set of features, where:

figure 1 - wall element made of logs in the collection;

figure 2 is the same, side view A;

figure 3 is an enlarged fragmentary image of the upper bars with racks;

figure 4 is a cross section bb rack in the area of the groove;

figure 5 is a view of B on a log in the spike area.

Wall building element (see figure 1, 2) contains logs 1, stacked one on top of the other with insulation 2 between them. Neighboring logs 1 are interconnected by spaced apart elements 3 of the type of dovetail. The ends of the logs 1 are made with spikes "a" rectangular in plan (see figure 5, view B).

Corner and intermediate racks 4 and 5, respectively, for two-story buildings can be made floor and through. In addition to the upper parts of the uprights 4, 5, they have longitudinal grooves “c” with rectangular cross sections (see Fig. 4) for accommodating the spikes “a” of logs 1 in them. The upper beam 6 (log) (see Fig. 3) with a spike "c" connected to the groove "d" on the racks 4, 5 "in the paw", ie by connecting a trapezoidal section, which prevents the possible collapse of the log walls and gives the structure the necessary rigidity. The use of a lifting mechanism (crane, not shown in the drawing) is aimed at accelerating construction work at the expense of mechanization and block construction. Slings 7 (see Fig. 1, 2) can be fastened both under the lower beam 1 (beam) of the wall element and under its upper beam 1.

Assembly of the wall building element is as follows.

Harvest logs 1 of the same length. On the lower side of each log 1, a longitudinal groove and transverse grooves are made from the lower and upper sides for the connecting element 3. At the ends of the logs 1, spikes “a” are made.

After that, the lower log 1 is laid with the transverse grooves up, then a layer of insulation 2 (tow) is laid on it and the second log 1 is laid on top of the insulation 2 with a longitudinal groove so that the transverse grooves under element 3 are aligned. After this log 1

connected by elements 3. In a similar manner, the third upper log 1 is attached, while observing the alignment of the faces of the spikes “a” on the ends in a plane.

The assembled wall building element by means of slings 7 and a lifting mechanism (not shown in the drawing) is lifted and installed above the ends of the racks 4, 5, the spikes “a” are combined with the grooves “b” and lowered between the racks. Similarly, fill the entire opening between the racks 4, 5, leaving a reserve place for the upper log (beam 6). The beam 6 is lifted, put into a reserve place so that its spikes “c” enter the grooves “d” on the racks 4, 5, forming a “paw” connection, keeping the walls from collapse and providing the structure with the necessary rigidity.

The use of prefabricated wall elements from logs will speed up and reduce the cost of construction of low-rise wooden houses due to the arising opportunity to mechanize the process of their assembly.
