Description

A bridge mid-span closing device

technical field

The utility model relates to the field of bridges, in particular to a bridge mid-span closing device.

Background technique

Bridges generally refer to structures that are erected on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountain streams, bad geology or to meet other traffic needs. In the construction of the hanging basket cantilever method of the cantilevered continuous beam, the traditional mid-span closure construction process often removes one end of the hanging basket, and the other end of the hanging basket is converted into a bracket; in the nth section (a total of n 1) After the construction tension is completed, first construct the side span closed section, after the construction of the side span closed section is completed and tensioned, remove one set of hanging baskets in the mid-span, and move the other set of hanging baskets on the mid-span side to the other side as a whole. At the cantilever end, insert the wire rope into the reserved hole at the cantilever end to hoist the front beam of the hanging basket and the front beam of the sliding beam, remove the front hanging rod of the hanging basket, use the winch to move the bottom basket and the sliding beam to the corresponding position, install the anchor rod, The hanger and the coupling are used to anchor and stabilize the hanger and the formwork system, and the main truss system is removed; the traditional construction process has a relatively long construction period, and after the construction of the equilateral span closing section is completed and tensioned, one set of hanging baskets is retreated, and the other After the platform hanging basket is in place, the bracket is used for construction; the force point of the front beam is converted from the boom to the wire rope, and then from the wire rope to the boom, the process is more complicated and the operation risk during the conversion process is relatively large.

Detailed ways

The specific embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

As shown in Figures 1 to 3, the present utility model includes a hanging basket bracket 1, the hanging basket bracket 1 is a rhombus frame with an acute angle, and the upper side of the hanging basket bracket 1 is provided with a vertical position at the acute angle and can move up and down. The rod 2, the lower end of the vertical rod 2 is provided with a flat plate 3, the flat plate 3 is fixedly connected with the vertical rod 2, the flat plate 3 can move up and down with the vertical rod 2, and the two flat plates 3 can fit together;

The lower end of the hanging basket bracket 1 is provided with a vertically placed supporting rod 4, the supporting rod 4 can move up and down, the lower end of the supporting rod 4 is equipped with a wedge-shaped block 5, the upper end surface of the wedge-shaped block 5 is an inclined plane, and the lower end of the hanging basket bracket 1 is located in the support One side of the rod 4 is equipped with a chain guide chain hoist 6 .

The vertical rod 2 passes through the hanging basket bracket 1, the upper end of the vertical rod 2 is provided with a threaded groove, and the threaded groove is provided with a nut, the vertical rod 2 is placed on the hanging basket bracket 1 through the nut, and the vertical rod 2 is made to pass through the nut. Moving up and down.

The vertical rod 2 is made of high-strength finish-rolled rebar.

The supporting rod 4 passes through the lower end of the hanging basket bracket 1, the upper end of the supporting rod 4 is provided with a threaded groove, and a nut is installed on the threaded groove, the supporting rod 4 is placed at the lower end of the hanging basket bracket 1 through the nut, and the nut makes the supporting rod 4 move up and down .

The number of the support rods 4 is multiple, the support rods 4 are placed left and right, and the material of the support rods 4 is high-strength finish-rolled threaded steel.

When the utility model is used, when the continuous pouring beam section 7 on the front side of the closure needs to be poured, the two hanging basket supports 1 are respectively placed on the beam 9 on the corresponding side of the continuous pouring beam section 7, and the two hanging basket supports 1 The acute angles on the upper side are adjacent;

Fixing of the hanging basket bracket 1: place the lower end of the support rod 4 on the lower side of the beam 9, and rotate the nut on the support rod 4 to make the upper end face of the wedge block 5 contact the lower end face of the beam 9. Since the upper end face of the wedge block 5 is Inclined surface, the upper end surface of the wedge block 5 and the lower end surface of the beam 9 can be closely attached to prevent the swing of the hanging basket bracket 1; 6.
