The method for performing the reinforced wire concrete building structures

 

(57) Abstract:

Usage: in the field of construction for concrete building structures on the site, mainly for the manufacture of reinforced concrete slabs, beams, etc. in the repair, renovation or restoration of buildings. The essence of the invention: method execution reinforced wire concrete building structures includes tension reinforcement wire to anchor the device to the length and/or width of the structures in the form of a parallel beam, a beam voltage wire them twisting, the location of hard reinforcement in the form or formwork and its monolithic pouring of concrete. The anchoring device is rigidly fixed against each other in the walls of the room in which you install the overlay, anchors pull parallel beams, consisting of two or more wires, and the voltage of the armature is produced by twisting each of the beams; each beam is divided lengthwise into two or more pairs of approximately equal parts, between which the beams of insert sleeves that using the lever rotates around the axis of the wire, providing the same Curling with about what to perform concrete building structures on the site, mainly for the manufacture of reinforced concrete slabs, beams, etc. in the repair, renovation or restoration of buildings by replacing loose bearing floor slabs without the complete destruction of the old roofing and floors.

Known processes for the manufacture of concrete building structures like slabs-slabs on fixed installations with performance valves of the rods, bundles of wire, tape material in the form of a combination of rods and mesh design with its preliminary tension by tension, for example, by hydraulic cylinders with advanced electric heating, twisting rotation of the ends in opposite directions, for example, using faceplates, tension rods with pre-mounted nets V-shaped clamps, etc., location of reinforcement in the form or formwork and concreting pouring concrete.

The disadvantages of the known methods of construction of structures type of floors are the need for special facilities, devices with heat and tension reinforcement, their inability to perform on-site installation and the complexity of the installation finished building structures that require the complete destruction of the buildings.

Known closest to the claimed technical solution is selected as the closest analogue, the way the tension beam reinforcement in the manufacture of prestressed concrete building structures, including tension reinforcement wire on fixed against each other anchoring devices on the length and/or width of the structures in the form of parallel beams, consisting of two or more wires, voltage wire bundles their twisting through the sleeve, the rotatable around the axis of the wire with equal its curl on both sides of the sleeve [1].

The disadvantages of this method are the non-implementation of tension in the room with limiting the length of the reinforcement walls and uneven placement of reinforcing material in concrete structures, in particular in the middle and at the ends, which reduces the bearing capacity of the structure.

The objective of the invention is a developing method for performing the reinforced pre-stressed concrete wire building structures of the type of joists, beams, etc., allowing their production with simultaneous installation, including the execution of lane>The problem is solved due to the fact that the use of signs known method for performing the reinforced wire concrete building structures, including tension reinforcement wire rigidly fixed against each other anchoring devices on the length and/or width of the structures in the form of parallel beams, consisting of two or more wires, voltage wire bundles their twisting through the sleeve, the rotatable around the axis of the wire with equal its curl on both sides of the sleeve, in accordance with the invention, the anchoring devices are secured in the walls of the room in which you install the overlap, each of the beams divided by the length of the two or more pairs of approximately equal parts, between which in bunches insert sleeve, the rotation of the sleeves is realized by means of the lever, and after the tension reinforcement is placed in a mold or formwork and zamonolichivajut its pouring concrete.

In accordance with a preferred variant implementation of the invention, the beams subjected to tension wire pull on the anchor device in several parallel rows, the distance between which is less than the length of the levers and the levers after red rod reinforcing elements and provide the pulling up and additional voltage wire.

When performing a method for repair of buildings without complete destruction of the concrete slab overlay performed without removing the old beams, remaining inside pour the concrete mixture design, and as formwork use ceiling floor below the floor.

Due to the combination of distinctive features of the proposed technical solution is achieved to manufacture and pre-stressed reinforced concrete without special devices such as hydraulic cylinders, rotating platters with actuators, etc. that allows the execution of concrete structures directly at the place of their installation, repair, reconstruction, etc. of buildings - performance floors without complete destruction of the roof and the old ceiling.

Due to the preliminary hard mounting in walls of anchor devices and run the valve in one piece with them, achieves overlap integral rosenovo with the walls. At this time, the valve performs carrier function.

The overlap set without specifically performed in the walls of the recesses serving as supports, as is the case when installing the finished slabs-slabs.

Overlap can have the poison with the building.

In Fig. 1 presents a parallel bundles of wire stretched over the anchor device, side view; Fig. 2 - the same, top view; Fig. 3 - parallel bundles of twisted wire, side view; Fig. 4 is a top view of Fig. 5 - sleeve levers, brought under the neighboring row wire; Fig. 6 is a valve overlap, installed without removing the old beams, side view; Fig. 7 is a top view.

Presented on Fig. 1 and 2, the method for performing the reinforced wire concrete building structures type of slabs in the embodiment, when the renovation of the building includes a full or partial preservation of old beams and ceiling coverings removing the old ceiling, rigid attachment by screwing with the incorporation concrete placed against each other anchoring devices 1 wall 2 rooms, which set the ceiling, pulling on the anchor device parallel beams 3, consisting of two or more reinforcing wires and the voltage of the valve by twisting each of the beams. Each of the beams divided by the length of the two or more pairs of approximately equal parts, between which in bunches insert sleeve 4, which through lever 5 rotates around the axis ol the governmental ranks of the beams is chosen slightly smaller, than the length of the levers, and the levers after twisting slid under the wire adjacent rows (Fig. 3). The arms function as a transverse reinforcing rod elements and provide pulling the wire up and create additional stress.

When repair and reconstruction of the building of overlap can be performed without removing the old beams 6, which remain inside pour the concrete mixture design (Fig. 4).

The monolithic valves make filling concrete mixture into the form, produced around reinforcement in the form of executable overlap. In case of preservation of the ceiling surfaces, below the floor, they can be used instead of the formwork.

As the reinforcing wire may be used as a normal metal wire type wire", and any other aging resistant wire, including synthetic.

The method can be implemented in the construction industry, mainly in the repair of old buildings, using known techniques, technologies and materials.
