Description
Technical Field
The utility model relates to a pavement and pavement lay technical field, especially relate to a but leveling device based on precast concrete pavement slab.
Background
At present, in pavement and pavement engineering, a precast concrete pavement slab is often used as a rigid cement concrete pavement. The cement concrete pavement needs to meet the requirements of stable and comfortable driving and certain requirements on pavement evenness. How to control the single precast concrete pavement slab to be kept on a horizontal plane when the single precast concrete pavement slab is laid, so that the pavement paved by each single precast pavement slab forms a whole, which is a difficult point in pavement construction and is also a key technology of precast concrete pavement slab construction.
Disclosure of Invention
For solving the technical problem who exists among the known art, the utility model provides a but leveling device based on precast concrete pavement slab can realize that the road surface keeps at a horizontal plane when pavement slab lays.
In order to achieve the purpose, the invention adopts the following technical scheme:
a leveling device based on precast concrete slabs comprises lifting devices arranged at four corners of a precast slab, wherein each lifting device consists of a lifting ring, a leveling screw and a steel cylinder, and the upper end of the steel cylinder is in threaded connection with the lifting ring through a threaded hole; the lower end of the steel cylinder is in threaded connection with the leveling screw through a threaded hole; the steel cylinder consists of an upper steel cylinder, a lower steel cylinder and a base, and the upper steel cylinder is in threaded connection with the lower steel cylinder; the lower steel cylinder is welded with the base; the base is provided with a threaded core hole connected with the leveling screw in a threaded manner, and grouting holes are uniformly distributed around the threaded core hole of the base.
Due to the adoption of the technical scheme, the utility model discloses following superiority has:
the utility model provides a but leveling device based on precast concrete pavement slab, prefabricates single concrete pavement slab earlier promptly, can the leveling when laying for each single pavement slab forms a smooth road surface and pavement, can satisfy the driving requirement, and its superiority is as follows:
1. the precast slab and the leveling device are combined into a whole, so that the structure is simple; 2. the hanging ring can be detached, and the surface layer flatness does not need post-treatment; 3. the height of the prefabricated road panel can be adjusted within a certain range, so that construction is facilitated; 4. the leveling can be carried out on the upper part of the surface layer of the prefabricated pavement slab, the operation is convenient, and the construction progress is accelerated.

Detailed Description
In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings:
as shown in fig. 1, 2 and 3, the leveling device based on the precast concrete slab comprises lifting devices arranged at four corners of a precast slab 1, wherein each lifting device consists of a lifting ring 2.5, a leveling screw 2.3 and a steel cylinder, and the upper end of the steel cylinder is in threaded connection with the lifting ring 2.5 through a threaded hole; the lower end of the steel cylinder is in threaded connection with a leveling screw 2.3 through a threaded hole; the steel cylinder consists of an upper steel cylinder 2.1, a lower steel cylinder 2.2 and a base 2.4, wherein the upper steel cylinder 2.1 is in threaded connection with the lower steel cylinder 2.2; the lower steel cylinder 2.2 is welded with the base 2.4; the base 2.4 is provided with a thread core hole connected with the leveling screw 2.3 in a threaded manner, and grouting holes are uniformly distributed on the periphery of the thread core hole of the base 2.4.
A leveling method of a leveling device based on a precast concrete pavement slab comprises the following specific implementation steps:
1) firstly, four lifting devices are arranged at four corners of a precast slab and are used for leveling a single precast slab; namely, four leveling lifting devices are installed in four corner preformed holes or drilled holes on the precast concrete pavement slab.
2) Placing two vertical horizontal rulers on the surface layer of the single precast slab, wherein when water beads of the two vertical horizontal rulers are respectively positioned at the center, the surface layer of the precast slab reaches the level; when the water beads of the two vertical horizontal scales deviate from the center respectively, the surface layer of the prefabricated slab does not reach the level, and the surface layer of the prefabricated slab needs to be leveled;
3) and taking out the lifting rings 1 of the four lifting devices, and adjusting the screwing height of the leveling screws 2.3 by using a screwdriver at one end of the water bead deviating from the centers of the two vertical horizontal rulers to enable the water beads of the two vertical horizontal rulers to be positioned at the center, and adjusting the surface layer of the precast slab to be horizontal, thereby finishing leveling.
When the precast concrete pavement slab is leveled, the operation can be carried out on the top of the surface layer of the concrete pavement slab, and the leveling height range of the pavement slab is 0 cm-3 cm
The construction method of the levelable precast concrete pavement slab can adopt a plurality of levelable precast concrete pavement slabs to quickly finish paving a road or a platform, and the specific implementation is as follows: after the installation operation of the first single road panel is finished, the installation operation of the next single road panel is respectively installed in four directions of the first single road panel, and the leveling of the next single road panel is the same as the installation operation method of the first single road panel; namely, the installation operation of paving roads or platforms is completed quickly.
Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and those skilled in the art can make many modifications without departing from the spirit and scope of the present invention as defined in the appended claims.
