SU744087A1 - Reinforcement for building structures - Google Patents

Description

The purpose of the invention is to increase the strength of structures.

For this, in reinforcement for building structures containing interconnected sheets of non-metallic woven material, each sheet is made with a bend at opposite ends and a middle part curved in the form of a gutter, and the sheets are joined together by successive mutual engagement of adjacent bends.

In FIG. 1 shows a reinforcement sheet, general view; in FIG. 2 - reinforcement sheets in connected positions, side view; in FIG. 3 - the same; after monolithic sheets in polymer concrete, plan.

The reinforcement comprises sheets 1 of non-metallic wicker material, which can be cut from cloths or made from pieces of square weaving tapes. Each sheet 1 is made with bends 2 at opposite ends and a curved middle part in the form of a groove 3 having the greatest curvature in the middle part and a smooth transition into the flat end parts of the sheet. To fix this form of sheets 1, they are impregnated with a curing binder, for example epoxy resin. Sheets 1 are connected in series with each other by meshing adjacent

The invention relates to reinforcement for building structures made of non-metallic materials.

Known reinforcing element, consisting of a rod made on the basis of polymeric materials, the surface of which is covered with a layer of sand, fixed by means of a cured polymer binder [1].

To reinforce building structures, it is necessary to assemble frames from such reinforcement using fixing elements, which requires additional reinforcing work.

Also known reinforcement containing rods of non-metallic material, fastened together by their ends, and spacers installed between the rods [2].

The disadvantage of such reinforcement is the complexity of its manufacture.

Closest to the invention is reinforcement for building structures, containing interconnected sheets of non-metallic woven material [3].

This reinforcement provides for a layer-by-layer pair connection of sheets, therefore, the structures reinforced by it have low tensile and bending strength.

bends 2 and filled into polymer concrete with the formation of the rod 4.

The fittings are made as follows.

Sheets 1 are connected by means of bends 2 into a serial chain and fixed in a form to form a rod 4. The chain of sheets 1 is fastened to an extent to bend bends 2, after which polymer concrete is poured into the farm, to create conditions for prestressing, a load is applied, under which bends 2 are pressed to the plane of sheets 1. After hardening of the polymer concrete, the load is removed.

When the rod 4 of the reinforcement is used in a monolith of a building structure, the tension of the bends of 2 sheets 1 tend to be unbent, however, this is prevented by the anchoring of the sheets 1 in the middle part due to bending in the form of a groove 3, polymer concrete around the ends of the sheets 1 and the adhesion of the bends 2 to each other. For the rod 4 to bend it oriented so that the load acts in the plane of the sheets 1.

Frames 4 can be made of rods by tying them with ropes impregnated with a hardening binder, after which the connection nodes are coated with polymer concrete to prevent alkali from concrete of building structures.

Several chains of sequentially 5 connected sheets 1 can also be monolithic in the rod 4, chains can also be assembled from multilayer sheets 1, and the places of their bends can be reinforced with additional locking elements.
