Problems solved by technology

However, prefabricated concrete slabs only effectively shorten the curing time. When hoisting concrete slabs, positioning the slab position and subsequent leveling still take up a lot of time and manpower and material resources
However, the existing leveling products have a small contact surface with concrete and single functions, which is not conducive to controlling construction quality and construction progress

Embodiment 1

[0027] Such as Figure 1-5 Shown, a kind of method for leveling prefabricated concrete road slab comprises the steps:

[0028] S1: Screw the plug hole bolt 4 into the upper and lower ends of the claw-shaped embedded part 2 to seal the claw-shaped embedded part 2;

[0029] S2: placing the claw-type embedded part 2 on the bottom of the precast concrete form 1, and pouring concrete into the precast concrete form 1;

[0030] S3: After the concrete is initially set in the precast concrete formwork 1, the plug hole bolt 4 is removed;

[0031] S4: Screw the hoisting bolt 4 into the claw-type embedded part 2, and hoist the precast concrete formwork 1 to a preset position through the hoisting bolt 7;

[0032] S5: Remove the lifting bolt 7, screw the leveling bolt 10 into the claw-type embedded part 2, and level the precast concrete formwork 1 to a preset height through the leveling bolt 10, the A certain gap is formed between the prefabricated concrete formwork 1 and the original co...

Embodiment 2

[0037] Such as Figure 1-5 As shown, the concrete structure includes a precast concrete formwork 1, and claw-type embedded parts 2 are arranged in the precast concrete formwork 1.

[0038] The claw-shaped embedded part 2 is a steel round pipe with internal threads.

[0039] A plurality of claw-shaped support structures 3 are welded to the lower part of the steel circular tube.

[0040] The claw-shaped embedded part 2 is adapted to the plug hole bolt 4, and the plug hole bolt 4 is composed of a steel hexagon socket bolt 5 and a plastic regular hexagon plug hole 6.

[0041] The claw-type embedded part 2 is adapted to the lifting bolt 7, and the lifting bolt 7 is composed of a bolt 8 and a lifting ring 9 welded on the top of the bolt.

[0042] The claw-shaped embedded part 2 is adapted to the leveling bolt 10, and the leveling bolt 10 is a regular hexagonal bolt inside.

[0043] In the specific technical solution of the present invention, the main body of the claw-shaped embed...

Abstract

The invention discloses a method for leveling a prefabricated concrete pavement slab. The method comprises the following steps: (1) screwing plug bolts into the upper and lower ends of a claw-shaped embedded part to seal the claw-shaped embedded part; (2) laying the claw-shaped embedded part at the bottom of a precast concrete formwork and pouring concrete into the precast concrete formwork; (3) removing the plug bolts after the concrete is initially set in the precast concrete formwork; (4) screwing a hoisting bolt into the claw-shaped embedded part and hoisting the precast concrete formwork to a preset position by the hoisting bolt; (5) removing the hoisting bolt, screwing a leveling bolt into the claw-shaped embedded part and leveling the precast concrete formwork to a preset height by the leveling bolt; (6) conducting grouting to fill voids formed between the precast concrete formwork and an original concrete formwork. The invention also discloses a concrete structure. The concrete structure and the method for leveling the prefabricated concrete pavement slab have the advantages of simplifying the construction process, controlling the construction period and saving the construction cost.

Description

technical field [0001] The invention relates to a method and structure for repairing road slabs, in particular to a concrete structure and a method for leveling a prefabricated and assembled concrete road slab, and belongs to the technical field of rapid repair of composite road surfaces. Background technique [0002] With the development of society, the traffic volume is increasing day by day. On the one hand, the huge traffic volume means that the road surface and bridges are operated beyond the design load, which inevitably produces various diseases; on the other hand, it also means that roads, especially road surface diseases The maintenance construction will cause a lot of congestion, so it is not allowed to spend too long on maintenance. In order to achieve the purpose of efficient and rapid maintenance and reduce the impact of road maintenance on traffic volume, the construction method of precast concrete slabs came into being. However, the prefabricated concrete sla...
