Embodiment 1

[0025] like figure 1 and figure 2 As shown, this embodiment provides a polyurethane compression-resistant floor structure. An aluminum-plastic board 2 is arranged on the periphery of the track and field equipment 1. A rigid base layer 3 and a gypsum base are laid on the periphery of the aluminum-plastic board 2 from bottom to top. A leveling layer 4 , on which the aluminum-plastic plate 2 and the gypsum-based leveling layer 4 are laid, a polyurethane elastic material middle coating 5 and a water-based polyurethane topcoat 6 .

[0026] Further, the height of the aluminum-plastic plate 2 along the axial direction of the track and field equipment does not exceed the height of the gypsum-based leveling layer 4 along the axial direction of the wall column.

[0027] Because this structure is equipped with an aluminum-plastic plate between the track and field equipment and the leveling layer, on the one hand, it can relieve the weight of the track and field equipment on the floor ...

Embodiment 2

[0029] Polyurethane compression-resistant floor structure, a layer of aluminum-plastic board is arranged around the track and field equipment, and a rigid base layer and a gypsum-based leveling layer are laid on the periphery of the aluminum-plastic board from bottom to top. A middle coat of polyurethane elastic material and a top coat of water-based polyurethane are laid on the top of the layer.

[0030] The rigid base is composed of the following components in parts by weight: 120 parts of cement, 50 parts of graded sand, 25 parts of gravel, and 40 parts of crosslinking agent.

[0031] The coating in the polyurethane elastic material is composed of the following components in parts by weight: 60 parts of elastic glue, 45 parts of waste tire powder, and 10 parts of waste plastic.

[0032] The composition of the elastic glue is: 20 wt% polyethylene terephthalate, 25 wt% polyether N330, 7 wt% 2-methylpentamethylenediamine, 10 wt% neopentyl glycol, 25 wt% hexamethylene diisocyan...

Embodiment 3

[0040] Polyurethane compression-resistant floor structure, a layer of aluminum-plastic board is arranged around the track and field equipment, and a rigid base layer and a gypsum-based leveling layer are laid on the periphery of the aluminum-plastic board from bottom to top. A middle coat of polyurethane elastic material and a top coat of water-based polyurethane are laid on the top of the layer.

[0041] The height of the aluminum-plastic plate along the axial direction of the track and field equipment does not exceed the height of the gypsum-based leveling layer along the axial direction of the track and field equipment.

[0042] As mentioned above, the aluminum-plastic plate is bonded with the rigid base layer and the gypsum-based leveling layer through elastic glue.

[0043] The rigid base layer is composed of the following components in parts by weight: 130 parts of cement, 40 parts of graded sand, 20 parts of gravel, and 35 parts of crosslinking agent.

[0044] The midd...

Abstract

The invention belongs to the field of construction of floors of outdoor sports places, and particularly relates to a polyurethane compression-tolerant floor structure and a construction method thereof. The polyurethane compression-tolerant floor structure is provided with a layer of aluminum plastic plate around track and field equipment, a rigid base layer and a gypsum-based leveling layer are paved at the periphery of the aluminum plastic plate from bottom to top, and a polyurethane elastic material intermediate coating and a water borne polyurethane top coating are arranged above the aluminum plastic plate and the gypsum-based leveling layer. The structure disclosed by the invention can effectively relieve the heavy pressure of track and field equipment to the floor during use, and the hollowing and cracking of the floor around the track and field equipment is avoided.

Description

technical field [0001] The invention belongs to the construction field of polyurethane floors, and in particular relates to a polyurethane compression-resistant floor structure and a construction method thereof. Background technique [0002] In addition to traditional functions such as anti-skid and anti-aging, the floor used in sports venues also needs to have compression resistance, because sports venues often need to install track and field equipment. When track and field equipment is in use, it will put heavy pressure on the surrounding floor. If the floor has poor compression resistance and cannot recover its elasticity, cracks will easily form around the equipment. Contents of the invention [0003] The object of the present invention is to provide a polyurethane compression-resistant floor structure and its construction method in view of the deficiencies in the prior art. The structure can effectively withstand the heavy pressure of track and field equipment and re...
