Problems solved by technology

[0002] Sulfur mortar anchoring construction technology is widely used in railway and bridge engineering, but it is rarely used in industrial and civil buildings. With the construction of large workshops and large equipment, the paved tracks in industrial plants have become It has become a part of many plant constructions. The traditional anchoring method is generally the embedded bolt method, but this method has poor ability to withstand dynamic loads and is prone to quality and safety accidents.

Embodiment Construction

[0009] Steel guide rail sulfur mortar anchoring method of the present invention, construction according to the following steps:

[0010] 1. Track foundation construction: The track foundation is a reinforced concrete ground beam, and its construction process requirements are the same as those of the concrete structure in housing construction. Its strength, cross-sectional size, axis position, surface flatness, and molding quality must be guaranteed. The main problems here are the axis of the concrete and the flatness of the surface, which should be controlled during the construction process.

[0011] 2. Setting out the bolt position and drilling holes for spikes: According to the requirements of the drawings, release the position line of the spikes according to the axis position of the threaded spikes, and use an electric hammer to drill holes on the concrete track foundation. It must be operated by a special person. The hole diameter is 4mm larger than the diameter of the spik...

Abstract

The invention relates to an anchoring method of steel guide rail sulfur mortar. The anchoring method of steel guide rail sulfur mortar includes the following steps of constructing rail foundation, conducting paying off at the bolt position, punching holes of spikes, preparing construction material, boiling the sulfur mortar, pouring the sulfur mortar, installing bolts, installing press plates, installing the guide rail, measuring the guide rail, rechecking the guide rail, and adjusting errors of the guide rail. Compared with the prior art, the anchoring method of the steel guide rail sulfur mortar has the advantages that the boiling process of the sulfur mortar is simple, large machinery and equipment are not applied, construction is relatively concise and convenient due to good grasp of material selection and control of the boiling temperature, the sulfur mortar strength is high in generation speed, the anchoring time is short, the anchoring effect is good, and the sulfur mortar is excellent in anti-frost performance, anti-fatigue performance and capacity of bearing reloading. In addition, an overlength guide rail is high in installation precision and large in installation difficulty.

Description

technical field [0001] The invention relates to a building construction method, in particular to a sulfur mortar anchoring method for steel guide rails. Background technique [0002] Sulfur mortar anchoring construction technology is widely used in railway and bridge engineering, but it is rarely used in industrial and civil buildings. With the construction of large workshops and large equipment, the track pavement in industrial plants has become As a part of many plant constructions, the traditional anchoring method is generally the embedded bolt method, but this method has poor ability to withstand dynamic loads and is prone to quality and safety accidents. Contents of the invention [0003] The object of the present invention is to provide a sulfur mortar anchoring method for steel guide rails. [0004] In order to solve the above-mentioned technical problems, the steel guide rail sulfur mortar anchoring method of the present invention is constructed according to t...
