Abstract

The inventive Utility Model relates to the field of bridge building and can be used in the design and construction of bridges for multifunctional purposes in order to save the bridge from destruction during various vibrations and during an earthquake.

An earthquake-resistant support unit consists of a column (Fig. 1) formed by two triangular hollow columns (1, 2), a tubular conductor (Fig. 4), and multilayer support pipes A (7) and B (8). Two triangular hollow columns are interconnected by tape bandages (3). When building columns vertically (14, 15), a quadrangular insert is provided (Fig. 5 (13)) with a slot under the “tongue” located between the columns (14, 15). The “tongue” (4) of column 2 enters the cavity of column 1. This insert protects the column joints from horizontal displacements and gives the entire structure flexibility. The tubular conductor (5) is located on a truncated tubular pyramid (6), which in turn is mounted on the end of the column. With serial shocks of the earthquake, the column (Fig. 1) moving upward will press on the truncated tubular pyramid (6), on which the support sheets of the conductor (11) rest (mounted at a 45-degree angle on a door-type device) and mounted on the conductor with clamps (not indicated). The support sheets are pivotally connected to the conductor frame and rest on a truncated tubular pyramid at an angle of 45 degrees. At the sectioned tubular pyramid (6) moving together with the column upwards, it will slide under the supporting sheets to open all four sheets on which supporting pipes B (8) and A (7) are suspended in the grooves (10) on the cables (17), covering the column from the sides. Ropes pass through the gutters, and the gutters from above are closed by retaining plates so that the cables do not jump out during an earthquake. In the pipe A there is a T-shaped insert (16), (fixing for the cable) along the width of the conductor frame. Pipes B (8) are installed under the pipe A (7) at a certain distance, and are fastened together by banding belts (12). On the conductor above the supporting sheets are installed restrictive cables (9) that perform safety functions. The support sheets are hollow inside, and have a thickness that hides the diameter of the cable in the gutter (10). When the column moves down, the support sheets from a vertical position will be installed again at an angle of 45 degrees, on a truncated tubular pyramid (6). The advantage of the conductor is large seismic resistance, simple and reliable, the ability to adjust the height of the support pipes by placing adjustment sheets under the tubular pyramid (6 ) and pipe A (7). If the column goes down (in case of breakage or failure), the column will not pull the entire structure down.

Implementation of a utility model.

The inventive utility model "Earthquake-resistant reference site" relates to the field of bridge construction and can be used in the design and construction of bridges for multifunctional purposes in order to save the bridge from destruction during various vibrations and during an earthquake.

An earthquake-resistant support unit consists of a column (Fig. 1) formed by two triangular hollow columns (1, 2), a tubular conductor (Fig. 4), and multilayer support pipes A (7) and B (8). Two triangular hollow columns are interconnected by tape bandages (3). When building columns vertically (14, 15), a quadrangular insert of fig. 5 (13) with a slot under the “tongue” located between the columns (14, 15). The “tongue” (4) of column 2 enters the cavity of column 1. This insert protects the column joints from horizontal displacements and gives the entire structure flexibility. The tubular conductor (5) is located on a truncated tubular pyramid (6), which in turn is mounted on the end of the column.

With serial shocks of the earthquake, the column (Fig. 1) moving upward will press on the truncated tubular pyramid (6), on which the support sheets of the conductor (11) rest (mounted at a 45-degree angle on a door-type device) and mounted on the conductor with clamps (not indicated). The support sheets are pivotally connected to the conductor frame and rest on a truncated tubular pyramid at an angle of 45 degrees. The truncated tubular pyramid (6) moving together with the column upwards, will slide open under the support sheets all four sheets on which support pipes B (8) and A (7) are suspended in the grooves (10), covering the column with sides. Ropes pass through the gutters, and the gutters from above are closed by retaining plates so that the cables do not jump out during an earthquake. In the pipe A there is a T-shaped insert (16), (fixing for the cable) along the width of the conductor frame. Pipes B (8) are installed under the pipe A (7) at a certain distance, and are fastened together by banding belts (12). On the conductor above the supporting sheets are installed restrictive cables (9) that perform safety functions. The support sheets are hollow inside, and have a thickness that hides the diameter of the cable in the gutter (10). When the column moves down, the support sheets from a vertical position will again be installed at an angle of 45 degrees, on a truncated tubular pyramid (6). The advantage of the conductor is great earthquake resistance, simple and reliable, the ability to adjust the height of the support pipes, by attaching adjustment sheets to the tubular pyramid (6) and pipe A (7). If the column goes down (in case of breakage or failure), the column will not pull the entire structure down.

The scope of earthquake-resistant columns with a conductor is various bridges, overpasses, overpasses, moorings and other supporting structures. This technical solution allows you to save the bridge from destruction during various vibrations and during an earthquake.
