Expansion joint padding belt for preventing sport field plastic from swelling or collapsing and method for producing expansion joint padding belt

Abstract

The invention provides an expansion joint padding belt for preventing sport field plastic from swelling or collapsing and a method for producing the expansion joint padding belt. The method comprises the following steps of cutting down two adjacent road beds along two angles corresponding to an expansion joint, so as to form a groove of which the longitudinal section is a trapezoid; filling the expansion joint padding belt into the whole groove, and keeping the expansion joint padding belt parallel to the surfaces of the road beds; coating adhesives on the expansion joint padding belt and the road beds adjacent to the expansion joint padding belt, and further adding adhesive tapes so as to integrally fix the expansion joint padding belt with the adjacent road beds; and penetrating a fine steel wire inside the expansion joint padding belt through the interior of an expansion joint padding belt body, wherein the longitudinal section of the expansion joint padding belt body is a trapezoid, the expansion joint padding belt body is integrally formed by bonding elastic plastic grains through adhesives, and the weight ratio of the adhesives to the elastic plastic grains is 1:(3-6). Due to adoption of the expansion joint padding belt, the plastic paved on a sport field is prevented from swelling or collapsing because of thermal expansion and cold shrinkage, then the quality problem of the plastic sport field is prevented.

Description

【Technical field】 [0001] The invention relates to an expansion joint filler belt for preventing plastic bulge or collapse in sports fields and a realization method. 【Background technique】 [0002] Plastic runways are divided into prefabricated plastic runways, all-plastic plastic runways, breathable plastic runways and hybrid plastic runways. The construction method of the existing hybrid plastic runway is as follows: firstly, on the completed asphalt concrete base, the plastic slurry with two-part mixed polyurethane slurry as the base material is spread to form a plastic surface layer, and then the plastic surface layer that has not yet been fully cured Spray the colloidal particles on the surface, so that the colloidal particles and the plastic surface layer are bonded together and solidified to form a plastic runway. Or directly make a plastic runway model, and then lay it on the base. [0003] The asphalt concrete base, that is, the roadbed, is a belt-shaped structure ...

AI Technical Summary

Problems solved by technology

Due to the influence of temperature, at the expansion joints between the venues, the plastic on the venue often bulges or collapses due to thermal expansion and contraction, resulting in quality problems in the plastic sports production area, which brings inconvenience to people active on the sports venue.

At the same time, repairing construction work is also very inconvenient
