Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of water gate trench construction, and relates to a reinforcing and grout-stopping device for trench embedded part construction. BACKGROUND

[0002] Traditional water gate trench embedded part construction is generally two-stage embedding on the basis of the first-stage concrete of the gate trench, and then pouring the second-stage concrete. First, the first-stage concrete is poured, and the space for the second-stage concrete is reserved when the first-stage concrete is poured. After the first-stage concrete is poured, the trench embedded part is installed, and then the second-stage concrete is poured. After the first-stage concrete is poured, the subsequent installation of the trench embedded part and pouring of the second-stage concrete generally takes 3 months to half a year. There is a gap between the formwork and the trench embedded part, and the overflow of the concrete slurry affects the pouring quality of the concrete around the embedded part. SUMMARY

After the rotary handle 8 is rotated clockwise by 90 degrees, the right side of the pressing rod 2 is in close contact with the inner side of the vertical plate of the trench embedded part 1. The threaded section of the pull rod 5 cooperates with the fastening nut 7. The pull rod 5 moves to the right by rotating the fastening nut 7 clockwise with a wrench. The pressing rod 2 presses the front vertical plate of the trench embedded part 1 by rotating the fastening nut 7 counterclockwise with a wrench. After the rotary handle 8 is rotated counterclockwise by 90 degrees, the pressing rod 2 and the blocking plate 3 are adjusted to be horizontal. The pull rod 5 is pushed to the right with the hand. After the pressing rod 2 passes through the second hole on the formwork 4 to the right, the blocking plate 3 is located in the second hole on the formwork 4. The limiting pin 6 welded with the pull rod 5 is in close contact with the inner side of the vertical wall of the box body opposite to the formwork.

[0006] The rubber strip 11 is connected between the box body bottom plate and the clamping plate 9 through a plurality of bolts 10. The left end of the rubber strip 11 is in close contact with the outer side of the front vertical plate of the trench embedded part 1. After the fastening bolt 10 is tightened, the thickness of the rubber strip 11 is 4-6 mm.

[0007] Several rectangular boxes are welded at intervals of 500mm in the height direction of the template 4.

[0011] (2) adopt the stop mortar mechanism, and form a stop mortar between the door slot embedded part and the template surface, which has certain elasticity, and under the extrusion of the tensioning device, seals the gap between the door slot embedded part and the template surface, plays the role of preventing overflow and stopping mortar.

[0012] (3) adopt the limiting mechanism, and open the through hole of φ4 on the device pull rod, and install the split pin or the stop pin, prevents the pull rod from being pulled out and falling off from the device.

[0013] (4) adopt the gyration mechanism, and the square shaft head is turned on the end of the device pull rod, and installs the round handle or the rocker, and the pull rod is linked to the tensioning reinforcing mechanism by rotating the handle or the rocker, and switches between the two functions of tensioning embedded part and plugging reserved hole.

[0014] The utility model discloses a beneficial effect

[0015] by the pressure bar 2, the door slot embedded part 1 is pressed, and then the fastening nut 7 is tightened to press and reinforce the template 4 and the door slot embedded part 1, and the rubber sheet 11 is also compressed and attached to the door slot embedded part 1 under the pressing force of the bolt 10, preventing the concrete slurry from overflowing and affecting the pouring quality of the embedded part surrounding concrete.

[0016] When the concrete pouring height approaches the height of the pressure bar 2, the pressure bar 2 can be retracted, and the hole on the template 4 is plugged by the plugging plate 3, so that the concrete can continue to be poured.

[0017] One is arranged at intervals of 500mm in the height direction of the template 4, and the door slot embedded part 1 is reinforced by all the tensioning pressure bars 2, so that the door slot embedded part 1, the template and the template frame body form a firm whole. One way is to support and reinforce the door slot embedded part through the inner supporting steel bar of the door slot embedded part with a spacing of about 1.5m, and the other way is to support and reinforce the door slot embedded part 1 through the rigidity of the template frame body. The two ways are used in combination, which is more stable and firm. As the concrete pouring height rises, the tensioning state of the pull rod is constantly converted into the plugging state, playing the role of stopping mortar and plugging. The utility model combines the first and second stages of the traditional door slot embedded part concrete construction into one construction period, shortens the construction period, reduces the construction cost, and improves the construction quality and efficiency.
