Description

The invention relates to the construction in earthquake-prone areas of buildings and structures.

The closest technical solution to the claimed object is an earthquake-resistant brick panel with dressing in half a brick of mortar bricks with holes in the middle of the width a quarter of the length from the ends of the brick into which damping rods are fixed, fixed on the pressure plate with nuts [patent RU 118331 U1 for useful model from 07/20/2012 - prototype].

The design of this brick panel has the following disadvantages. Due to the increased rigidity and the lack of effective damping multilayer elements, the rods are waveguides of mechanical vibrations, which not only in seismic conditions, but also during transport loads leads to the destruction of the panel.

A technically achievable result is an increase in the seismic resistance of a brick wall panel.

This is achieved by the fact that in the rod for a brick wall panel containing brickwork of bricks with holes in the middle of the width and one quarter of the length from the ends of the brick laid on the mortar with the holes in the channels aligned, and reinforcing bars passed through the channels with rigid fixation them at the ends, by means of flat stops in thickness equal to the thickness of the mortar seam, and in the channels at the ends of the panel there are layers of U-shaped vibro-damping material perceiving spatial vibration, reinforcing bars neither are damping, and each of them is a cylindrical damping element, to the ends of which flat rigid stops are rigidly attached, and the inner cavity is filled with a layer of vibration damping material, for example sand, while the density of the vibration damping layer is less than the density of the outer cylindrical shell of the damping element, and the layers of vibration damping material, structurally made of a U-shaped type, and perceiving spatial vibration, made of crushed worn autop lids on a bundle in the form of rubber glue, liquid glass, or a polymer binder, and every 8 ÷ 10 rows of bricks placed on the mortar, hard stops are welded, and the damping rods are lengthened by welding, and the mortar with crushed vibrated damping chips is poured into the channels of the middle zone tires of automobile tires for the formation of more rigid zones, and the reinforcing bars are made damping, and each of them is a coaxially arranged cylindrical shell, between which coaxially Tubular damping elements of vibration damping material are located, the ends of which are rigidly fixed by rigid stops and the inner central cavity is filled with sand, while the density of the layers of vibration damping material is less than the density of coaxially arranged cylindrical shells.

In FIG. 1 shows a brick (bearing element) in a perspective view with two holes; in FIG. 2 - earthquake-resistant brick wall panel, plan view, in FIG. 3 is a diagram of a damping rod of a brick wall panel; FIG. 4 is an embodiment of reinforcing bars in the form of a set of alternating cylindrical shells and tubular damping elements.

The rod (Figs. 3 and 4) is designed for a brick wall panel (Fig. 2) made of bricks 1 (Fig. 1) with two holes 2. Holes 2 are made in the middle of the width of the brick and one quarter of the length from the ends of the brick. In the combined openings 2 of the bricks 1, damping (reinforcing) rods 3 are placed (Fig. 3), at the ends of which are fixed flat stops 5 in thickness equal to the thickness of the mortar joint 4.

Each of the damping (reinforcing) rods 3 is a cylindrical damping element, the ends of which are rigidly attached (for example, by welding) to flat rigid stops 5, and the inner cavity is filled with a layer of vibration-damping material, for example sand, and the density of the vibration-damping layer should be less than the density of the external cylindrical shell of the damping element. If the density of the vibration damping layer and the outer cylindrical shell are equal, then the damping element 3 will lose its ability to dampen vibration, which is not permissible.

To increase the efficiency of damping shock loads and vibration in the channels designed to accommodate the mortar layer 4, at the ends of the panel (and on the side), layers 7 of vibration-damping material, structurally made of a U-shaped type, and perceiving spatial vibration, and made, for example, of crushed pneumatics tires (worn tires) on a bunch (rubber glue, water glass, polymer binder). After reaching the projected height of the panel for shrinkage of the layers of vibration damping material 7 in time, shutter speed and last hard stops are welded 5. The remaining gap (gap) is closed in the usual way.

As bricks (load-bearing elements), not only ceramic bricks can be used, but also (bricks) load-bearing elements made of synthetic materials, impregnated wood, hollow bricks filled with light vibration-absorbing and vibration-absorbing materials (not shown in the drawing).

A possible embodiment of the reinforcing bars in the form of a set of alternating cylindrical shells 3 and 6 (Fig. 4) and tubular damping elements 9, the number of which is selected taking into account the required damping, depending on the level of seismic protection of the object.

The reinforcing bars are made damping, and each of them is a coaxially located cylindrical shells 3 and 6, between which are coaxially located tubular damping elements 9 of vibration damping material, to the ends of which are rigidly fixed flat stops 5, and the inner Central cavity 8 is filled with sand, with this density of the layers of vibration-damping material is less than the density of coaxially arranged cylindrical shells 3 and 6.

Earthquake-resistant brick wall panel is mounted and provides vibration isolation as follows.

A layer of mortar 4 is applied between the columns on the foundation (not shown in the drawing). Flat rigid stops 5 are placed in the form of strips in the form of strips with vertically welded damping rods 3 welded to them 3 with a length of 1000 mm and a diameter of, for example, 16 mm, if the hole diameter is 2 brick is 20 mm, for example on a brick with a size of 70 × 120 × 250 mm. Every 8 ÷ 10 rows of bricks 1 laid on the mortar 1, hard stops 5 are welded, and the damping rods 3 are extended by welding. In order to save reinforcement in the channels of the middle zone, a solution with vibration damping crumb from crushed tire covers (worn out) can be poured to form more rigid zones.

The following embodiments of reinforcing damping rods 3 are possible.

Coaxially located cylindrical shells of reinforcing damping rods are perforated.

Polyurethane is used as the vibration damping material of the tubular damping elements.

Flat rigid stops connecting the end surfaces of coaxially arranged cylindrical shells of reinforcing damping rods are made combined, consisting of at least three layers: the lower and upper layers are made rigid, and the third layer located between them is made damping.

The earthquake-resistant brick wall panel in dynamics has the following features.

Shorter damping rods 3 of the reinforcement are not waveguides of mechanical vibrations, since the propagation of vibrations is prevented, firstly, by welding units with hard stops 5, and secondly, layers 6 of vibration damping material located in the damping rods themselves 3. When approaching waves of mechanical vibrations to the panel from the outside they are met by vibration damping material in layers 7 located in the channels at the ends of the panel, and dampened, preventing their penetration to the middle zone. Between the layer of mortar 4 and the surfaces of the hard stops 5, as well as bricks 1, an infinitely decreasing reflection of waves of mechanical vibrations occurs.

Compared with the prototype design, the proposed earthquake-resistant panel has the following advantages: the range of damping the fluctuations of mechanical effects due to complex design features is expanded: shorter reinforcing bars 3 and the presence of vibration-damping material 6 in their cavities, as well as layers 7 of vibration-damping material, structurally made U-shaped type and spaced around the perimeter of the panel.

In addition, it is possible to dock panels by welding outlets of flat rigid stops 5.

Installation of floor beams is carried out by welding of U-shaped overlays on a brick (not shown in the drawing), which simultaneously serve as stops 5, rigidly connected to the reinforcing bar 3. The panels are joined by welding outlets of flat rigid stops 5 (not shown in the drawing).

Installation of floor beams, fastening of pipelines, cables is carried out by welding their fastenings to U-shaped transverse overlays for bricks, at the same time performing the function of rigid stops 5, rigidly connected to the reinforcing bar 3.

An earthquake-resistant panel can be used in the construction of vehicle bodies by using bricks made of light and durable materials, impregnated wood, plastics, synthetic mixtures, microporous materials.
