[0002] At present, the construction of dual-purpose track for conductive transportation in China is mostly according to the general construction method, placing ordinary anchor bolts in the anchor bolt holes, and then grouting with sulfur cement mortar on site. Often due to the complex and harsh site environment, it is difficult to ensure the bolts are in good condition after grouting. Ground insulation, frequent rework, resulting in a lot of waste of manpower, material resources and time

Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] A method for making insulating bolts on site, the method comprises the following steps:
[0020] 1) Make the mold box: the structure of the mold box is as follows figure 1 As shown, the mold box includes a bottom plate 1 and four steel plates 2 of the same size, and the thickness of the steel plates 2 is 3-5 mm. Four steel plates 2 form a rectangular tube, in which two opposite steel plates are sandwiched between other two opposite steel plates, baffles 3 are set on the outside of the sandwiched two steel plates, and the outside of the other two opposite steel plates 2 Pressing plates 4 are arranged respectively, and the pressing plates 4 are pressed on the steel plate 2 through the pressing plate bolts 5 at both ends. The bottom plate 1 is arranged at one end of the rectangular cylinder and is sealed with the port of the rec...

Abstract
The invention discloses a method for fabricating an insulating bolt on site. The method comprises the steps: 1) fabricating a mold box; 2) sieving sand; 3) fabricating an insulating material; 4) charging and heating, namely pouring the sand in a heating container for heating, adding silicate cement to the heating container, and finally, adding sulfur and paraffin to the heating container and then stirring and heating, wherein when melt is changed into sol from solid, the melt can be directly used as sulfur cement mortar; 5) mold box grouting, namely filling the sulfur cement mortar in the mold box; 6) demolding; and 7) insulating a naked lead screw. According to the method, in a construction site with a severe environment, the insulation degree of a foundation bolt fabricated by adopting the method can be greatly improved and the mounting quality of the foundation bolt can be ensured; the method is applicable to mounting a conducting transportation track; the on-site fabrication of the insulating bolt is realized, and the characteristics of cost saving, low environmental influence, high motility, stable and reliable quality and the like can be achieved; and therefore, the method is very suitable for popularization in building construction fields with the severe environment.
Description
technical field [0001] The invention relates to the prefabrication and installation of anchor bolts of a conductive transportation dual-purpose track for a low-voltage electric flat car, in particular to a method for making insulating bolts on site. Background technique [0002] At present, the construction of dual-purpose track for conductive transportation in China is mostly according to the general construction method, placing ordinary anchor bolts in the anchor bolt holes, and then grouting with sulfur cement mortar on site. Often due to the complex and harsh site environment, it is difficult to ensure the bolts are in good contact after grouting. Earth insulation, frequent rework, resulting in a lot of waste of manpower, material resources, and time. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a method for on-site production of insulating bolts, which is suitable for the installation of...
