Detailed Description

In order to fully illustrate the nature of the invention and the manner of practicing it, the following examples are given. The raw materials used in the following examples may be commercially available materials unless otherwise specified.

A manufacturing process of a naturally-curved simulated concrete expansion joint comprises the following steps:

(2) pouring concrete in the area A;

(3) after the concrete in the area A is initially set, removing the curve mold;

(6) pouring concrete in the area B;

Referring to fig. 1 and 3, the curve mold (plate) used in the present invention is made of resin type material by integral injection molding, and has a certain flexibility as a whole. It is in a wavy line shape along the length direction and can be bent integrally. Therefore, in the construction process, the expansion joint trend is set through integral bending, and the natural soil crack is simulated through the modeling of the curve mold.

The performance requirements of the curve form of the present invention are critical, while maintaining sufficient strength to withstand the compression of the concrete, yet being flexible to allow easy bending into the wave-like configuration. In order to satisfy the above requirements, the inventors finally found through a large number of experiments that a resin material of the following formulation is preferably used: polyamide resin (nylon 66): 50-60 parts by weight of styrene-butadiene-styrene block copolymer (SBS): 10-15 parts by weight of benzyl glycidyl ether: 5-10 parts by weight of aluminum hypophosphite: 10-15 parts by weight of melamine: 3-5 parts by weight of glass fiber powder: 3-5 parts by weight. The curve mold material prepared by injection molding the composition with the formula has the impact strength of 50-60kJ/m through detection²The elastic modulus is between 800-900MPa, which just meets the requirement of the invention and has good cutting processing capability.

The concrete poured in the areas A and B can be decorative concrete (colored concrete), so that the requirements of specific environments such as theme parks and the like are met.

After the area A is poured, the flexible expansion joint plate is used for replacing a curve mold, and then the area B is poured. The flexible seam expansion plate can be made of pearl wool or similar materials, the preset seam expansion line type of the curve mold can be well maintained in the construction process, and the flexible seam expansion plate flexibly connects the areas A and B to form an expansion seam capable of releasing expansion stress and contraction stress.

In specific applications, the flexible expansion joint plate can be in various colors, and materials close to the color of concrete are generally adopted. The flexible expansion joint plate is higher than the construction heights of the areas A and B, and after concrete in the area B is poured, the top end of the flexible expansion joint plate is polished in different directions by interweaving filiform edge tools such as steel brushes and the like until the flexible expansion joint plate is flush with the concrete surface.

In a preferred embodiment, the flexible expansion joint plate is higher than the construction height of the areas A and B, a weakening line (pin hole) is arranged between the raised part and the ground part, and the raised part is torn off along the weakening line after the concrete of the area B is poured.

In some cases, when the top end of the trimmed flexible expansion joint plate is slightly lower than the concrete surface, the joint filling glue can be filled, so that the expansion joint height and the concrete surface are kept flat.

Under the specific condition, when erecting the concrete area A template and the concrete area B template, the steps of binding steel bars and installing a force transmission device can be further arranged according to the requirement of ground strength.

In addition, in the above manufacturing process, when the formwork of the concrete area B is erected, the curved formwork may be provided at the other side edge position not adjacent to the area a, and the concrete of the area C is poured with reference to the above steps, so that expansion joints are formed also in the area B and the area C. And by analogy, a plurality of concrete ground structures imitating natural soil cracks are formed in the large-area ground pouring process.
