Detailed Description

The invention is further described with reference to the accompanying drawings.

As shown in fig. 1-4, a concrete pump pipe vertical section reinforcing apparatus comprises a formwork 1, a pump pipe connecting member 2, a steel wire rope 3, a rope clip 4, an adjustable bolt 5, a U-shaped embedded part 6, a floor slab 7 and a pump pipe 8.

Pump line connecting piece 2 sets up in 8 upper ends of pump lines, can carry out effective connection with the vertical section with the bend section of pump line 8 through pump line connecting piece 2.

The U-shaped embedded parts 6 are embedded in the floor slab 7, the number of the U-shaped embedded parts 6 is three, the U-shaped embedded parts 6 take the pump pipes as the circle centers, the projection of the fixed assembly on the horizontal plane as the radius, and the U-shaped embedded parts are uniformly distributed on the circumference according to the included angle of 120 degrees.

The fixed components are arranged in three numbers, and form a triangular pyramid frame structure with the floor structure. The fixing component consists of a steel wire rope 3, an adjustable bolt 5 and a rope clamp 4.

The upper end of the steel wire rope 3 is hooped at the connecting position of the pump pipe 8 and is fixed by 4 rope clamps; the specific mode is as follows: above the pump pipe connecting piece 2, the 3 rope heads of wire rope form the circular form of staple bolt around the concrete pump pipe, and the size of the inside round hole of staple bolt is between the external diameter of pump pipe external diameter and pump pipe strap, avoids the wire rope staple bolt from the slippage of pump pipe connecting piece department, causes the reinforcing apparatus inefficacy. The lower end of the steel wire rope 3 is provided with an adjustable bolt 5 and is fixed through 4 rope clamps, the other end of the adjustable bolt 5 is connected with a U-shaped embedded part, and the adjustable bolt 5 is used for adjusting the length of a fixing component, so that the perpendicularity of the vertical section of the concrete pump pipe is kept, and a fastening effect is achieved; the adjustable bolt 5 is arranged at the lower part of the fixing component and is close to the floor structure, so that the operation of workers is facilitated; simultaneously, fixed subassembly in the use, receive concrete pump pipe and can take place slight not hard up gradually under the effect of lasting vibrations, fixed subassembly sets up near the floor workman's discovery problem of being convenient for and in time fastens.

4 rope clamps at 3 both ends of wire rope in this embodiment, wherein be close to 3 level settings of wire rope between two rope clamps of junction, keep away from wire rope 3 between two rope clamps of junction and be the setting of U type arch, be convenient for observe on the wire rope 3 whether 3 rope clamps that are close to the junction are not hard up.

The angle between the wire rope 3 and the horizontal plane in this embodiment is between 45 degrees and 60 degrees, preferably 55 degrees.
