Embodiment 1

[0041] refer to Figure 1-4As shown, the present invention provides a hoisting and positioning device for prefabricated cement concrete paving slabs, comprising several positioning columns 1 and supporting platforms 5, the positioning columns 1 and the supporting platforms 5 are respectively connected on the roadbed, and the concrete paving slabs 2 are placed Between several positioning columns 1, four positioning plates 10 are arranged at equal intervals in the outer circumferential direction of the positioning columns 1, and the four positioning plates 10 are arranged vertically. A guide bracket 8 is inserted and connected, and the concrete deck board 2 is placed above several supporting platforms 5 .

[0042] First determine the position of the positioning plate 10, the positioning plate 10 is the main reference point of the entire road construction; the positioning plate 10 can locate the concrete deck 2; the support platform 5 is mainly used to carry the concrete deck 2 b...

Embodiment 2

[0045] refer to Figure 3-13 As shown, the difference between the positioning method of this embodiment and the first embodiment is only:

[0046] The further optimized solution also includes a plurality of sealing strips 4, a plurality of sealing strips 4 are vertically crossed and fixedly connected to each other, a plurality of supporting platforms 5 are arranged on the inner side of the sealing strips 4, the sealing strips 4 and the supporting platforms 5 are respectively fixedly connected on the roadbed, and the sealing strips 4 , The top surface of the support platform 5 and the bottom surface of the concrete paving panel 2 are set at the same height. The sealing strip 4 is mainly used to keep the mud under the concrete pavement 2 during the grouting process after the concrete paving plate 2 is laid for the construction road without leakage. After the mud is hardened, a good bonding effect is produced.

[0047] To further optimize the solution, the positioning column 1 i...

Embodiment 3

[0070] refer to Figure 4As shown, the difference between the positioning method of this embodiment and the second embodiment is only:

[0071] If the roadbed is soil ground, first use a measuring instrument to determine the positioning point; in steps 2 to 4, the cement concrete, positioning datum, sealing strip 4 and support platform 5 are fixedly connected by steel bars (not shown in the figure) to form a steel weave. network. The alignment process and the grouting process are the same as those in the first embodiment.

Abstract

The invention provides a hoisting and positioning device and method for a prefabricated cement concrete paving slab, comprising a plurality of positioning columns and a supporting platform, the positioning columns and the supporting platform are respectively connected to the roadbed, and the concrete paving plate is placed between the plurality of positioning columns The outer side of the positioning column is provided with four positioning plates at equal intervals, and the four positioning plates are vertically arranged. Several adjustment holes are opened on the concrete paving plate, and guide brackets are inserted into the adjustment holes, and the concrete paving plate is placed on a number of supports above the table. The invention can quickly realize the construction process of the prefabricated cement concrete paving board, and can quickly and accurately locate the position of each cement concrete paving board, and can also adjust the uneven position of the cement concrete paving board, with flexible construction and difficult construction. It is beneficial to improve the construction progress.

Description

technical field [0001] The invention belongs to the field of road construction positioning, and in particular relates to a hoisting positioning device and method for an assembled cement concrete paving slab. Background technique [0002] With the continuous expansion of urban areas and the increase of road mileage, the speed of replacement of roads is accelerated. On construction sites such as airstrip construction, housing construction, subway construction, underground pipeline laying, and underground sidewalk construction, it is usually Temporary roads need to be laid on the site. Traditional road expansion projects require on-site concrete pouring. Most of the temporary roads on construction sites in my country use one-time cast-in-place concrete, which takes up a lot of space on site, takes a long construction period, is seriously affected by weather, and causes serious interference to traffic. People's travel has a big impact. Concrete pouring will generate a large am...
