Description

The utility model relates to the construction and, in particular, to the design of the external wall unit and a monolithic basement over a cold or ventilated underground.

During the construction of residential and public buildings, the technology of erecting their frame from monolithic reinforced concrete is widely used.

It is known that on a monolithic overlap flush with its edge within each floor, masonry is made of small concrete blocks on which heat-insulating boards are attached from the outside (see Guryev V.V. et al. Effect of some parameters of porous fiber insulation on the cost-effectiveness of building thermal insulation / / Industrial and civil engineering. 1998, No. 5. P. 53-55). After that, facade systems with a ventilated air gap are installed (see Recommendations for the design and use for building and reconstruction of buildings in Moscow of facade systems with a ventilated air gap "Kraspan VST (N)". - M.: Moscomarchitecture, 2003. - 72 sec.) or the plaster is applied to the insulation on a grid fixed to anchors (see SP 12-101-98. Technical rules for the production of external thermal insulation of buildings with thin plaster on the insulation / Gosstroy of Russia. - M .: GUP TsPP, 1998. - 21 from.).

In areas of permafrost distribution, buildings are constructed with cold or ventilated undergrounds. In this case, the heat-conducting inclusion "reinforced concrete flooring - laying of small concrete blocks" is formed, which significantly reduces the heat transfer resistance of the corner connection "wall - basement flooring", as well as causing a decrease in the temperature of the floor surface of the first floor.

To reduce the influence of heat-conducting inclusion, sometimes additional insulation of the overlapping section from the underground is sometimes provided. In this case, a significant height of the underground should be provided, which leads to a rise in the cost of construction due to an increase in the height of foundations constructed from piles. In addition, the creation of thermal insulation at the bottom of the building is distinguished by the relative complexity and duration of work.

The objective of the utility model is a heat-efficient structural solution of the wall unit and the basement of the building.

The technical result obtained by using the utility model is expressed in the constructive solution of the wall unit and the basement of the building, in which the reduced resistance to heat transfer of the corner connection “wall - basement floor” and the exclusion of extended heat-conducting inclusion through the basement and concrete blocks of the wall fence are achieved.

To solve this problem, the design of the wall unit with the insulation fastened to the outer surface of the masonry from small concrete blocks erected on a monolithic reinforced concrete basement, while the ceiling with a layer of insulation is placed above a cold or ventilated underground, differs in that the masonry is made on reinforced concrete beams of equal width , which are based on local, protruding from the support floor with a width equal to the width of a small concrete block and placed in increments of 3 or more meters, and in forming Between them a gap is placed an effective heat-insulating material. To more effectively reduce the influence of heat-conducting inclusions when pouring local supports, structural lightweight concretes are used. Within the first floor, laying of small concrete blocks is done on beams. On the remaining floors, laying is done directly on the floors.

An analysis of the features of the claimed decision indicates the compliance of the claimed solution with the criterion of "novelty."

The combination of features of the utility model provides a solution to the stated technical problem, namely, a heat-efficient structural solution to the wall unit and the basement of the building.

The design of the wall unit (for example, facade systems with a ventilated air gap) and the basement of the building is illustrated by drawings, where in FIG. 1 shows a fragment of a node after casting a monolithic overlap with local supports and laying reinforced concrete beams on them; in FIG. 2 - section of the basement node and the wall outside the local reinforced concrete supports.

Local reinforced concrete supports 2 are made together during concreting of a monolithic basement 1. Reinforced concrete beams 3 are laid on the supports. Masonry is made of small concrete blocks 4 on the beams 5, onto which thermal insulation plates are mounted on the connectors 7. A layer of plaster is applied to the masonry. 6. With the creation of a ventilated air gap 8, facade panels 9 are hung on rails (not shown conditionally) 9. Thermal insulation plates 10 are laid on the basement 1, and they are cement an o-sand screed 11 is laid on a floor covering, for example linoleum 12.

The advantages of the claimed constructive solution of the wall unit and the basement of the building are:

- the exclusion of extended heat-conducting inclusion through the basement and concrete blocks of the wall fencing (except for heat-conducting inclusions in the form of local supports);

- placement of thermal insulation between the ceiling and the beam significantly increases the reduced resistance to heat transfer;

- an increase in the temperature of the inner surface of the wall and floor assembly (with the exception of local sections at the supports), which leads to an increase in the temperature of the floor surface;

- reducing the consumption of insulation due to its rational use.
