Hereinafter, a preferred embodiment of the footbridge frame and footbridge using the same according to the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, the same reference numerals will be used to denote the same or similar elements in all of the following drawings, and repetitive descriptions will be omitted. The following terms are defined in consideration of the functions of the present invention. It should be interpreted as meaning.

As illustrated in FIGS. 1 to 9, the deck frame 100 of the present invention is roughly composed of a main body 110, an anti-slip member 120, and a filler 130.

The main body 110 is formed of a lightweight aluminum material to form a long panel shape having an overall thin rectangular box-shaped cross-section, such as by extrusion molding, the first side for coupling with one end portion of the connection bracket 140 on one side cross-section. Coupling portion 112 is formed, and the other end surface is formed with a second coupling portion 113 for coupling with the other end portion of the connection bracket 140.

Here, the first coupling portion 112 and the second coupling portion 113 is a coupling groove having a roughly “c” shape formed in an inward direction on a cross section and formed of the same coupling form as one another, or one of them such as a spanner. In order to more easily insert and assemble the tool, for example, an assembly space 112a is formed in which an upper portion of the upper portion extends longer than the lower portion and forms a step, based on a coupling groove having a “c” shape.

Accordingly, when the main body 110 is fixed to the base frame 300, any one main body 110 and another main body 110 is mutually the first coupling portion 112 and the second coupling portion 113 Is connected by the connecting bracket 140, the assembly space 112a by the insertion and manipulation of the fastening tool, such as a spanner is easy to achieve a fast and robust fastening operation.

In addition, a plurality of spaces 111 connected by the partition wall 111a are formed in the body 110 so as to achieve weight loss and to structurally reinforce strength. At this time, the space 111 is preferably formed in each cross section is trapezoidal, triangular, square, hexagonal, etc. so as to structurally sufficiently support the pedestrian load.

Here, the cross section of the space 111 may be variously modified without being limited thereto as long as the weight of the main body 110 is light and structurally sufficient in addition to the above-described form.

In addition, the filler 111 is inserted into the space 111 is good heat insulating properties, low temperature characteristics and shock absorption.

Accordingly, in the winter, the filler 130 maintains the warming force of the main body 110 to prevent deformation due to shrinkage of each main body 110 that may occur due to the temperature difference, and maintains the cold power in summer It can prevent or reduce the deformation caused by the expansion of each main body 110, which may occur according to the difference, and also absorbs the vibration noise generated by the pedestrian's walking impact or the vehicle's operation can maintain a comfortable and comfortable stepping state. .

The non-slip member 120 is made of a granular body of irregular shape to form a thickness of 1 ~ 2mm, even and solid, and improve the shoe sole and traction of the pedestrian.

In this case, the non-slip member 120 is installed separately or in the same width and length as the upper surface of each of the main body 110 in order to facilitate maintenance.

Therefore, the non-slip member 120 fixed to the upper surface of the deck frame 100, the main body 110, each made of a panel form, if any one part is damaged, it is possible to easily replace only the damaged part. .

In addition, the granular body is preferably made of any one of various types of ceramics, sand or metal having good abrasion resistance of about 0.5 to 2 mm in size.

Accordingly, the non-slip member 120 has good abrasion resistance, and does not easily wear or be damaged even when the pedestrian is in contact with the sole of the shoe. It is possible to reliably prevent safety accidents caused by slipping of pedestrians.

The filler 130 is a polyurethane foam, which is a rigid or semi-rigid polyester foam that is evenly foamed by a prepolymer process, and the space 111 is easily inserted into the space 111 of the main body 110. It is preferable that it is formed in the same manner as.

For example, when the shape of the space 111 is formed in a triangle, the filler 130 is also formed in a triangle, and when the shape of the space 111 is formed in a trapezoidal shape, the filler 130 is also formed in a trapezoidal shape. .

Filler 130 having such a configuration is a polyurethane foam of light or rigid with good thermal insulation, sound insulation and low temperature characteristics, and shock absorption, as it is expanded polyester by the action of blowing agent (發泡劑). It is preferable to use.

Accordingly, the weight of the deck frame 100 is sufficiently reduced so as not to put a load on the bridge, and at the same time, the support strength for the safe walking of pedestrians can be further improved.

In addition, in winter, the filler 130 maintains the thermal insulation of the main body 110 to prevent deformation due to shrinkage of the main body 110, which may occur according to the temperature difference, and maintains the thermal insulation in summer It prevents the deformation due to the expansion phenomenon of the main body 110 that may occur.

In addition, by absorbing the pedestrian shock generated during the walking of the pedestrian or the vibration of the vehicle to solve the anxiety caused by the shaking of the footbridge can maintain a comfortable and comfortable stepping state at all times.

Hereinafter, a process of constructing footbridges using the deck frame having the above configuration will be described.

First, as shown in Figure 8, both sides or one side wall 510 of the bridge using a fastening means such as anchor bolts (girder) means a beam that supports the construction structure, usually I-shaped or box-shaped cross section It is designed to reduce its own weight, and to be able to resist three-dimensionally against bending, torsion, horizontal loads, etc.).

Next, a plurality of base frames 300 are installed along the longitudinal direction on the upper surface of the girder 200 such that the base frame 300 extends in the width direction of the bridge by welding or bolting.

Subsequently, the upper surface of the base frame 300, the first coupling portion 112 for coupling with one end portion of the connection bracket 140 is formed on one side cross-section, the other side of the other end of the connection bracket 140 A second coupling portion 113 is formed to be coupled to the first portion, and each deck frame is formed with a partition 111a having a space 111 for structural strength reinforcement while achieving weight loss inside. 100 is fastened and fixed by the fastening member 141 and the connection bracket 140.

At this time, since the assembly space 112a is formed in the first coupling portion 112 or the second coupling portion 113, the connection bracket 140 is connected to the first coupling portion 112 and the second coupling portion 113. After the two ends are combined, a fastening tool such as a spanner can be easily inserted and a smooth operation of the fastening tool can be performed. Thus, the main body 110 of the deck frame 100 can be quickly and firmly attached to the base frame 300. Can be fixed.

Subsequently, one side of the deck frame 100 is provided with a guard rail 400 for the safety of pedestrians.

In addition, an illumination lamp (not shown) is inserted into the lower side of the guard rail 400 so that an illumination installation space 410 is formed to facilitate safety by securing a view of a pedestrian when walking at night.

Here, the front surface of the lighting installation space 410 is preferably formed of a transparent plastic window for the projection of light such as a lamp, the back is preferably formed of a metal or synthetic resin.

Therefore, the pedestrian absorbs the vibration noise generated by the pedestrian shock generated when walking by the foot bridge 1000 installed in this way or the vehicle's operation, thereby eliminating the anxiety because the foot bridge 1000 is not shaken or slipped, and is slippery. The prevention member 120 can prevent the slip can prevent a safety accident to be provided with a comfortable and comfortable walking feeling.

On the other hand, Figures 10 and 11 is a cross-sectional view of the main portion showing another embodiment of the main body 110 according to the present invention, which trapezoidal space 111 formed in the main body 110 of the deck frame 120 By forming a and triangle, it is possible to more firmly support the load pressure of the pedestrians generated during walking, thereby double the bearing capacity of the deck frame 100 to improve stability and significantly reduce the weight of the deck frame 100 itself It is possible to avoid the load on the bridge.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. And will be apparent to those skilled in the art to which the invention pertains.
