Problems solved by technology

[0007] The purpose of the present invention is to provide a kind of concrete to solve a series of problems that the track floor in the prior art cannot meet the increasingly stringent requirements of super flat, super hard and easy to discolor, by improving the concrete used in the track floor The concrete formula greatly improves the early and late strength of the track floor and achieves the effect of superhard wear resistance. At the same time, the improvement of the early strength of the concrete greatly reduces the degree of deformation of the track floor during the initial setting of the concrete, thus Achieved the super flat goal

Embodiment 1

[0034] This embodiment provides a concrete for track floor, which is used to solve the problem that the early strength of ordinary concrete is low, resulting in excessive height difference of the concrete floor due to uneven shrinkage after the concrete undergoes a hydration reaction process.

[0035] Because fly ash and mineral powder have similar chemical components to cement, fly ash or mineral powder is generally used to replace cement, but both fly ash and mineral powder will reduce the early strength of concrete. After a lot of experiments, the inventor found that the early strength of concrete was not high, which would make it difficult to control the height difference of the concrete floor. Therefore, the inventor specially developed concrete with improved early strength. In the concrete of this embodiment, it is forbidden to add fly ash and mineral powder to the concrete, so as to improve the early strength of the concrete.

[0036] Improving the hydration reaction co...

Embodiment 2

[0050] This embodiment takes the construction of the concrete colored track floor of a single-track amusement vehicle in a large-scale playground project as an example. It is necessary to run single-track amusement vehicles in the interior, so the track floor of this part must not only have sufficient strength, but also have sufficient flatness, wear resistance and anti-skid performance.

[0051] The track floor in this embodiment includes a foundation floor, a concrete floor and a surface course. Wherein, the concrete floor is fixed on the foundation floor, and the surface layer is covered on the concrete floor and consolidated with the concrete floor. In order to ensure the flatness of the track floor, the concrete material used for the concrete floor is the concrete of the first embodiment.

[0052] In addition, in order to improve the wear resistance and anti-slip performance of the track floor, the inventors specially developed a superhard, wear-resistant and anti-slip s...

Embodiment 3

[0071] In order to further solve the problem of decreased flatness of the track floor due to the construction process, the inventor has specially developed a formwork system for the construction of the track floor in the second embodiment. Attached below figure 2 to attach Figure 8 The template system of this embodiment is explained in detail.

[0072] Such as figure 2 As shown, the formwork system 100 used to complete the construction of the track floor in the second embodiment includes a set of formwork groups 1 set opposite to each other. The formwork group 1 and the foundation floor 2 enclose an area 3 to be poured. Such as image 3 As shown, the template group 1 includes a horizontal template, and the horizontal template includes a horizontal lower template 4 and a horizontal upper template 5. The horizontal lower template is fixed on the foundation floor 2 by adjusting bolts 6, and the adjusting bolts 6 are located at one end of the horizontal lower template 4. Th...

Abstract

The invention provides concrete for a track terrace, and the concrete is used for solving a series of problems that the track terrace can not meet the requirements for excessive flatness, excessive hardness, decoloring and the like in the prior art. The concrete comprises the following components in percentage by weight: 10%-25% of terrace cement, 30%-40% of sand, 35%-50% of gravels, 5%-10% of water, 0.15%-0.7% of high-efficiency water reducing agents and 0.005%-0.015% of fibers. The concrete provided by the invention can be used for solving the problem of low early strength of track terrace concrete by improving a concrete formula, preventing the track terrace from generating the phenomenon of water bleeding in the initial congealing process of the concrete and controlling the deformation degree of the concrete track terrace and meets the requirements for using functions of excessive hardness and abrasion resistance of the track terrace through the great enhancement of the integral strength of the concrete.

Description

technical field [0001] The invention relates to the technical field of building decoration construction, in particular to concrete used for track floors. Background technique [0002] In all kinds of large-scale playgrounds, amusement vehicles have become one of the indispensable amusement facilities. The track design of amusement vehicles divides the floor into the track area and the non-track area. There is a height difference between the floor of the track area and the non-track area, and the floor of the non-track area should be higher than the track area. Among them, the construction quality of the track floor plays a decisive role in the safe operation of amusement vehicles. [0003] In order to increase the fun and excitement of the amusement vehicle, the design of the amusement track usually adopts a variety of complex curve combinations, and the train will run faster. There are many and sharp curves on the amusement track, and it is a closed loop. The complicated ...
