Lightweight construction slab and method of its manufacturing

FIELD: construction.

SUBSTANCE: invention relates to a lightweight construction slab, in compliance with the restrictive part of paragraph 1 of the claim, to the use of lightweight construction slab to create the building shell, in compliance with the restrictive part of paragraph 10 of the claim; and to the method of manufacturing the lightweight construction slab, in compliance with the restrictive part of paragraph 11 of the claim. A lightweight construction slab (100) with a rectangular base shape and flatly interconnected layers (01, 02, 03, 04 …), each of which is formed by a plurality (20) of boards (2). The boards (2) of each layer (01, 02, 03, 04, …) on their lateral surfaces are connected with one another on the sides and on at least one principal surface (205, 205') have a plurality of grooves parallel to one another. The boards of the first and the second layer (01, 02) are oriented at a first acute angle (+α, -α) from 25 to 60° with respect to the longitudinal side surfaces (200, 200') of the lightweight construction slab (100). The boards (2) of the first layer (01) are oriented with respect to the boards (2) of the second layer (02) at an angle (2α). The lightweight construction slab (100) on at least two longitudinal lateral surfaces (101, 101') parallel to each other has at least one connecting tongue (102) and a connecting ridge (102') interacting with it with the form closure, for connecting with the form closure on both sides with lightweight construction slabs (100) made in the same manner. Wherein the boards of at least one layer are connected at the sides to one another with the form closure through the tongue (202) and the ridge (202), and the boards (2) of at least one layer (01, 02) located in the middle stratum (Ml) on both sides (205, 205') or, respectively, on both main surfaces (205, 205') are equipped with a first and a second plurality of grooves (3, 3') crossing one another at angles (γ) from 5 to 100°, the grooves of each plurality passing parallel to one another. The application of a lightweight construction slab and the method for manufacturing a lightweight construction slab are also described.

EFFECT: finding a simple solution, by means of which it is possible to make lightweight construction slabs having no tensions, if possible, with a sufficiently high elasticity and a high residual strength at strong bending; the possibility for applying the lightweight construction slabs in buildings in places subject to earthquake hazards should be ensured.

FIELD: process engineering.

SUBSTANCE: invention relates to woodworking industry and may be used for making slats. Said composition includes for inner layer 10-40% of rotten blank waste chips and 20% of wastes after roundup lumber chips as well as 40-70% of chips produced from pulp chips of PS grade with the help of binder based on low-molecular urea-formaldehyde resin and emulsion. Note here that said binder consists of low-molecular urea-formaldehyde resin of 60-62% concentration and aqueous solution of ammonia chloride of 20% concentration. Emulsion consists of the following components, in wt %: paraffin - 21, brown coal wax - 14, emulsifier - 1, water - 64.

EFFECT: lower material input, power savings, higher efficiency of equipment, lower toxicity.

FIELD: construction, particularly building elements of relatively thin form for the construction of parts of buildings.

SUBSTANCE: panel comprises timber base formed of parallel board-like construction members. Timber base has at least two construction members. Each construction member is formed of two boards obtained by log sawing and includes at least partial wane sections. The boards are laid one onto another and are glued with each other so that narrow facial surfaces thereof rest one upon another.

EFFECT: decreased weight.
