Abstract

According to an embodiment of the present invention, a floor panel used in a footbridge comprises: a frame portion; a mortar layer including a reinforcing material by being located inside the frame portion; and a stone layer formed on the mortar layer inside the frame portion.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a floor panel,

The present invention relates to a bridge, and a floor panel and a method of manufacturing the same.

Bridges such as bridge bridges, which are located on the sides of bridges or bridges and allow people to pass through, are constructed by stone dry joining methods that fix the stone dry.

The stone dry bonding method may be vulnerable to vibration because the bridge is supported by the adhesive force of the anchor bolts and the adhesive. In order to secure sufficient strength for stability, the thickness of the stone must be increased to increase the weight. In this case, it is difficult to install a lightweight bridge. If you use wood instead of stone to reduce the weight, if the snow or rain falls, it is very slippery and if it is used for a long time, corrosion and damage may occur.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG. A manufacturing method of a floor panel and a floor panel manufactured thereby will be described in detail, and then a foot bridge including the foot bridge will be described.

FIGS. 1A to 1E are cross-sectional views illustrating a method of manufacturing a floor panel according to an embodiment of the present invention. And FIG. 2 is a perspective view showing a frame portion of the floor panel shown in FIG. Fig. 1A is a cross-sectional view taken along the line I-I in Fig.

First, a frame portion 110 as shown in Figs. 1A and 2 is prepared. The frame portion 110 receives and reinforces the strength of the mortar layer (reference numeral 120 in Fig. 1), and the stone layer (reference numeral 130 in Fig. The frame 110 may be formed of various materials, for example, high-strength aluminum.

Specifically, the frame portion 110 includes a bottom plate 112 constituting the bottom, an outer frame portion 114 formed along the edge of the bottom plate 112 and constituting a side outer frame, And a plurality of vertical portions 116 formed on the bottom plate 112 at the bottom plate 112.

Here, the vertical portion 116 can improve the resistance against load and vibration against the vertical load. The plurality of vertical portions 116 may be formed in parallel with each other to have a stripe shape. At this time, the vertical portion 116 may be located in a direction crossing the longitudinal direction of the bridge 100. This will be explained later, while explaining the foot bridge 100. Here, the height of the vertical portion 116 may be smaller than the height of the outer frame portion 114. The mortar layer 120 is positioned in the space defined by the vertical part 116 and the stone layer 130 is positioned on the vertical part 116 and the mortar layer 120. [ However, the present invention is not limited thereto, and the shape, height, and the like of the vertical portion 116 may be variously modified.

Inside or below the vertical portion 116, a tension bar fixing portion (not shown) to which a tension bar (reference numeral 68 in FIG. For example, the tension bar fixing part may be a space located inside the vertical part 116, and the tension bar 68 may be fitted into the space inside the vertical part 116 and fixed to the tension bar fixing part. However, the present invention is not limited thereto, and various methods can be used for the tension bar 68 and the fixing structure of the tension bar fixing part. The tension bar 68 located at the tension bar fixing portion is fixed to the bridge 100 so as to maintain a constant tension pressure. The tension bar 68 will be described later in more detail.

1B, an adhesive layer 140 may be formed between the frame 110 and the mortar layer 120 to improve bonding properties of the frame 110 and the frame 110, as shown in FIG. 1B . The adhesive layer 140 may be located only up to the height where the vertical portion 116 is formed. As the adhesive layer 140, various known materials capable of bonding the frame portion 110 and the mortar layer 120 can be used. However, the present invention is not limited thereto. The position and material of the adhesive layer 140 may be variously modified, and it is also possible not to carry out the process of forming the adhesive layer 140.

Subsequently, as shown in Fig. 1C, the mortar-forming layer 120a is placed in the interior of the frame portion 110 (more precisely, on the adhesive layer 140 inside the frame portion 110). The mortar forming layer 120a may comprise mortar and a reinforcing material. The mortar forming layer 120a may be formed to have the same or similar height as the height of the vertical portion 116.

As mortar, flexible mortar with high tensile properties can be used. For example, the mortar may include lightweight aggregate such as cement, silica sand, perlite or vermiculite, and polymer resin. The strength can be improved by silica sand and a lightweight material, and the tensile performance can be improved by the polymer resin.

As the reinforcing material, various materials capable of improving the strength can be used. For example, as the reinforcing material, fiber reinforcing materials such as glass fiber and carbon fiber can be used. Glass fiber, carbon fiber and the like are excellent in elasticity and strength, and can improve the mechanical properties of the mortar layer 120 formed by boding the mortar-forming layer 120a, thereby improving the strength and rigidity. In this case, for example, the mortar formation layer 120a can be formed by forming the reinforcing material into a mesh shape and placing the mortar in a state where the reinforcing material of the mesh shape is positioned in the frame portion 110. [ Then, the reinforcing material is integrated and is simple to handle, and the reinforcing material can be uniformly positioned in the mortar-forming layer 120a, thereby improving the strength-improving effect. However, the present invention is not limited to the above, and the material, shape and the like of the reinforcing material may be variously modified.

Then, as shown in Fig. 1D, the stone layer 130 is placed on the mortar forming layer 120a. The stone layer 130 may include various materials that can be used as a footing stone. For example, the stone layer 130 may be made of inexpensive granite, porcelain, artificial stone, or the like. The thickness of the stone layer 130 may have a thickness of 20 mm to 50 mm. When the stone layer 130 has such a thickness, the bottom panel 10 can be made lighter and have sufficient strength. However, the present invention is not limited thereto, and the stone layer 130 may have various thicknesses.

Next, as shown in Fig. 1E, the mortar layer 120a is cured to form the mortar layer 120. [0052] Next, as shown in Fig. Various methods known as the curing of the mortar forming layer 120a can be used. Thus, the floor panel 10 in which the frame portion 110, the mortar layer 120, and the stone layer 130 are integrated is manufactured.

The floor panel 10 manufactured by the above-described manufacturing method is less prone to occurrence of failure or the like even if it is used for a long period of time by using a natural stone or artificial stone, without causing discoloration or discoloration. Thus, the maintenance cost of the floor panel 10 can be reduced. Also, it is possible to stably walk by the stone of the stone layer 130 and to minimize the slip during walking. The strength and tensile properties of the bottom panel 10 can be improved by the laminated structure of the frame part 110, the mortar layer 120 including the reinforcing material, and the stone layer 130.

Hereinafter, an example of the bridge 100 including the floor panel 10 will be described in detail with reference to FIGS. 3 to 5. FIG.
