Embodiment Construction

[0019] The present invention is described in further detail below in conjunction with accompanying drawing:

[0020] Such as figure 1 , 2 As shown, the process of the present invention can be divided into two stages, one is the installation and manufacturing process of the precast slab steel formwork; the other is the pouring and manufacturing process of the precast slab.

[0021] The first stage:

[0022] The precast plate steel formwork is a rectangular structure, which is composed of a bottom plate 1 and four side plates 2, 3, 4, 5 assembled. Steel form bottom plate 1 is made of 12mm thick steel plate with a size of 1200×1600mm, and the back side is made of 8# channel steel welded frame. Before production, the frame must be welded separately on a special platform (flatness less than 1mm). After checking that the flatness of the frame is less than 2mm, the frame and the bottom plate are welded and connected. When welding the frame, it must be strictly noted that the leng...

Abstract

The invention discloses a manufacturing method for a special road-surface precast plate of a stimulated ice surface of a tire test field. The manufacturing method is characterized by comprising the following steps: manufacturing a precast plate steel template; drilling and turning over a pre-embedded tube circular hole; measuring bottom plate height difference; drilling a bolt hole in a bottom plate; checking the template, clearing impurities and coating a mould release agent; installing a pre-embedded part and a hanger; installing panel ceramic tiles and casting concrete; dismounting the mould, turning cover and checking. Compared with the prior art, the manufacturing method has the advantages as follows: advantages of other concrete component construction processes are integrated, a construction method is simple and easy to operate, the template is convenient to mount and dismount, production efficiency is greatly improved, a construction work-period is shortened, and the template and the hanger can be recycled. The technology has the remarkable advantage of being adaptive to various high-precision concrete prefabricated parts, and has very strong applicability and ascendency on construction of high-quality standard projects such as China car test fields and high speed railways, and similar concrete components.

Description

technical field [0001] The invention belongs to the field of building construction, and relates to a construction method of a special pavement precast slab, in particular to a method for manufacturing a special pavement precast slab for simulating an ice surface in a tire test field. Background technique [0002] The main function of the special road is to simulate various urban and rural roads in China and the Asia-Pacific region, to detect the driving conditions of the tires in various road conditions, and to collect various test data to provide test basis for tire design optimization and manufacturing improvement. However, during the manufacturing process of conventional concrete precast components, the structural size and surface accuracy are easily affected by the accuracy of the formwork and undergo significant changes, which seriously affect the structural parameters of concrete precast components. Contents of the invention [0003] In order to solve the above-menti...
