Description

The invention relates to devices for securing stressed reinforcement in wood building structures.

A device for fixing reinforcement in wooden structures is known, comprising thrust plates with lugs at the end under the grip for reinforcement and fixed fixing plates I on the lateral sides of the structure.

The disadvantage of this device is the complexity of its design, since the connection of the thrust plates with the fixing plates is made with the help of corners and pads welded to them, and the fixing of the plates to the structure is carried out using a set of bolts.

The purpose of the invention is to simplify the design of the device.

The goal is achieved by the fact that in a device for fixing reinforcement in wooden structures containing stop plates with knives at the end under the gripper for reinforcement and fixed fixings on the lateral sides of the structure, the stop plates are made with supporting lugs at the ends opposite to the ends of the straps , and installed in the grooves formed in the structure, and the fixing plates are located respectively above the eyes and under the supporting protrusions of the thrust plates.

In addition, the device is equipped with a cantilever strap installed between the thrust plates, which is made with a zaschinaya under the grip for reinforcement.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 view B in FIG. one; in fig. 4 - device mounted on a horizontal structural member; in fig. 5 - device with thrust plates fixed on the base plate and. with locking plates made with slits; in fig. 6 is type B in FIG. five; in fig. 7 is a view of FIG. five; in fig. 8 - thrust plates, side view; in fig. 9 is a view of D in FIG. eight; in fig. 10 - cantilever overlay, side view.

The device contains stop plates 1 with length 2 at the end under the grip 3 dl

reinforcement 4 and support protrusions 5 at the ends opposite to the ends with the strips 2. Plates 1 can be fixed on the support plate 6. Plates 1 are installed in the slots 7 formed in the wooden structure 8. Above the strips 2 and below the supporting tabs 5 of the plates 1 are installed fixing pads 9 fixed on the surface of the structure 8, for example, by means of the teeth 10. The pads 9 can be

made with slots 11 covering the thrust plates 1.

In order to reduce the shear forces acting on the plates 1, cantilever pads 12, made by e-rims 13 under the grip 3 for reinforcement, 2 stop plates 1 coaxially with the ribs, can be installed between them. The seams 2 of the plates 1 can be installed with projections beyond the edge of the structure 8 or located together with reinforcement 4 in channels 14,

formed in the construction of 8 and monolithic, for example, full merbeton.

The device is mounted as follows.

In places where the ends of the reinforcement 4 are fastened, grooves 7 are cut into the structure 8, into which

fixing plates 1 are installed. Then fixing pads 9 are fixed above the lugs 2 and below the supporting lugs 5 of the plates 1 on the surface of the structure 8. If necessary, cantilever lugs 12 are fixed between the plates, then fixings 4 are fixed to the plates 1, which 2 plates 1 are installed in the strips of the wires and 13 cantilever plates 12 in the strips of the strips and the armature is stressed by 4 known methods. When installing the openings 2 plates 1 in the channels 14 of the design 8 after tensioning the reinforcement, these channels are monolithic with polymer concrete.

The effectiveness of this device is to simplify its design by

0 excluding fasteners for joining thrust plates and fixing pads. In addition, it is necessary to use bolts to fasten the pads and the structure without reducing its carrying capacity.
