Description

TECHNICAL FIELD [0001] The present invention relates to a truss type soundproof tunnel structure,

The present invention relates to a truss type soundproof tunnel structure, and more particularly, to a truss type soundproof tunnel structure capable of securing structural safety while achieving weight reduction by constructing a steel pipe structure as a pillar member and a roof member, .

As a method to reduce traffic noise, it is best to eliminate or reduce the noise source. However, if the noise source can not be fundamentally blocked, such as roads and railroads, an indirect method of blocking or dispersing the noise propagation path should be used. Typical noise countermeasures by path blocking include soundproof walls and soundproof tunnels (tunnel-type soundproof walls).

The soundproof wall has a noise attenuation effect by using the negative diffraction attenuation characteristic which makes the propagation path longer by basically installing obstacles on the noise propagation path and transmitting the noise through the bypass path without being directly transmitted. Generally, the soundproof wall is composed of three parts: a foundation, a support, and a soundproof plate. The support is fixed to the foundation on the ground by an anchor bolt, and the soundproof plate is fixed to the support by clips and bolts. Since the sound barrier is a method of reducing the noise by using the damping distance damping phenomenon in terms of noise, there is a disadvantage in that it does not reduce the portion directly reaching the noise or diffracting. The damping effect by the sound barrier is generally about 10dB and 20dB when it has a reasonable height and length, but it is almost impossible to get 20dB of maximum attenuation.

In order to overcome the limitations of the sound attenuation effect of such a soundproof wall, the demand for a soundproof tunnel is increasing according to the environmental standard for the enhanced noise. Sound insulation tunnels are a typical method to increase the noise attenuation effect by minimizing the influence of diffracted sound generated over the entire upper and lower portions of the existing soundproof walls.

However, the conventional soundproofing tunnel has a problem that the weight of the soundproof tunnel is made heavy and the appearance is tight and the span of application is limited.

Prior art to be a background of the present invention is Korean No.1712833 "Noise Reduction Type Sound Insulation Tunnel and Method for Construction thereof" (Patent Document 1). This patent includes a pair of foundation concrete layers made of concrete having a predetermined height and width at regular intervals in the center, A base plate fixed to each of the foundation concrete layers with anchor bolts; An H beam fixedly installed in an arcuate shape across the base plate with bolts and nuts; A roof panel fixed to the upper end of the H beam by bolts and nuts and comprising a transparent panel and an external panel; A wall panel fixed to the H beam located at the lower end of the roof panel by bolts and nuts, the wall panel comprising an exterior panel and a transparent panel; An inner panel fixedly installed inside the H beam with bolts and nuts; And a noise shielding plate fixed to the inside of the upper end of the H beam by bolts and nuts.

However, the above background art has a problem that the frame of a sound-proof tunnel is formed of an H-shaped steel bent in an arch shape, which is heavy in weight, tight in appearance, and limited in span of application, and has a sliding insertion method in the case of roofing materials and soundproof panels In addition, it is not easy to replace the replacement part due to the breakage of the exterior material due to the sliding of the sliding member and the replacement of the replacement part due to aging, etc., due to vibration and structure displacement.

The present invention relates to a truss type sound insulation tunnel structure in which both a pillar member and a roof member constituting a skeleton of a sound insulation tunnel are constructed to have a truss structure of a steel pipe, thereby achieving a weight reduction and securing structural safety.

In the first embodiment of the truss-type soundproof tunnel structure of the present invention, only the roof soundproofing plate is installed at the bottom of the trussed roof member. In the second embodiment, the solar light module is additionally installed at the present time, It is possible to reduce the investment cost by using it as a solar power facility structure and air circulation is made in the space between the upper and lower sides of the truss type roof member to enable natural air cooling. Hereinafter, two embodiments will be described in detail with reference to the drawings.

1 is a perspective view showing a schematic configuration of a first embodiment of a truss type soundproof tunnel structure of the present invention.

As shown in FIG. 1, the first embodiment of the truss type sound insulation tunnel structure of the present invention includes a foundation concrete C installed along both sides of the road, and a foundation concrete C spaced at regular intervals along the longitudinal direction A truss-shaped roof member 20 connecting vertically erected steel pipe columns 10, an upper portion of the steel pipe column 10 facing each other, and two adjacent truss-shaped roof members 20 A plurality of braces 30, a plurality of side soundproofing plates 50 provided between the steel pipe columns 10 and a plurality of roof soundproofing plates 60 installed below the trussed roofing member 20 have.

That is, in the soundproof tunnel structure according to the present embodiment, the steel pipe column 10 and the truss roof member 20 are installed at regular intervals in the base concrete C, the plurality of truss roof members 20 are installed in the brace 30, And the soundproof plates 50 and 60 are installed on the side surface and the roof, respectively, to block the noise generated inside the soundproof tunnel structure.

In the construction of the soundproof tunnel according to the present embodiment, the construction of the foundation concrete (C) and the steel pipe column-foundation concrete structure for building the steel column 10 on the foundation concrete C are soundproofing using a skeleton constructed of a conventional H- So that a description thereof will be omitted and a difference from the conventional soundproof tunnel will be described in detail.

2 is a cross-sectional view of the truss-type sound-deadening tunnel structure of the present invention, excluding a soundproof plate, in which (a) is a front view, (b) is a sectional view taken along the line AA, to be.

2, the basic frame structure of the truss type sound insulation tunnel structure according to the present invention includes a truss roof member 20 and two steel column columns 10 and 10 supporting both ends of the truss roof member 20. [ .

Although a circular steel pipe having a circular cross section is shown in the figure as a steel pipe column 10, the present invention is not limited to a circular steel pipe but may also be constituted by a rectangular steel pipe. The steel pipe is a structural member that has no direction in stress when a load is applied, and is more efficient as a column member than a directional H-shaped steel. By constructing a column as a steel pipe, the required strength can be secured with less steel amount, There are advantages. In the present invention, the flange 12 may be integrally formed so as to protrude from the steel pipe main body 11 as in (B) in order to increase the rigidity of the steel pipe used as a column and improve the assembling property of the soundproofing plate.

The truss roof member 20 is connected to a truss-like shape using a steel pipe. The truss roof member 20 includes a phase current 21 and a phase current 21, which are configured to connect opposing steel columns 10 so as to have a constant curvature or slope. A plurality of oblique abdomen members 23 which are connected to each other by a predetermined distance from the lower end 22 and the upper end 21 and the lower end 22, . The inclined abdomen 23 adjacent to each other has a staggered inclination with respect to each other, for example, one oblique abdomen 23, which is joined at the same point of the lower current 22, The other oblique abdomen 23 adjacent to the obliquely abdomen 23 has an inclination and is coupled between the upper current 21 and the lower current 22 with an inclination of 135 degrees. In the truss, the warp belly material 23 is hinged to the upper current 21 and the lower current 22 so that only the axial force acts on the truss. In the present invention, however, the warp belly material 23 is in the upper phase 21 and the lower phase 22 22) is welded to the truss.

Although the upper current 21 and the lower current 22 are shown to have the same curvature in the drawing, they may be configured to have different curvatures so as to effectively cope with external forces acting on the roof member 20, The current 21 may be configured to have a unidirectional gradient, and the bottom current 22 may be formed to have a curvature.

A flange 22a is integrally formed so as to protrude downwardly from the lower end 22 as shown in Fig. 3C. The flange 22a increases the rigidity of the lower end 22 and facilitates assembly of the roof sound- Can be improved.

Both ends of the phase current 21 and the bottom current 22 constituting the truss-shaped roof member 20 are hinged to the steel pipe column 10 to constitute a unit frame frame of the soundproof tunnel. Since the truss column 10 is hinged to the truss column 10 by hinging (simple joining), only the compressive force acts on the column 10, which is advantageous in that the overall structure system becomes simple. However, the present invention is not limited to a structure in which the steel pipe column 10 and the truss roof member 20 are simply joined together, and they may be rigidly joined or semi-rigidly joined together to form a racene frame as a whole.

In this way, the frame frame composed of the steel pipe column 10 and the truss roof member 20 constitutes the unit frame of the soundproof tunnel and is installed at regular intervals along the longitudinal direction of the soundproof tunnel, and the roof soundproof panel and the side soundproof panel are installed. . Therefore, the sound-absorbing tunnel according to the present invention can reduce the weight of the entire structure compared to the sound-absorbing tunnel constituted by the conventional H-shaped steel frame, and it is possible to make the long span structure with a small weight by applying the truss- . It is preferable that the distance between the frame frames is about 2 m in order to prevent sagging of the roof sound insulation plate 60 while being affected by the size of the roof sound insulation plate 60.

3 is a plan view of the first embodiment of the present invention.

As shown in FIG. 3, the frame frames installed at regular intervals along the longitudinal direction of the soundproof tunnel are connected to each other by the braces 30 and act integrally with the external force. The braces 30 are arranged in an X-shape as shown in the drawing, and the braces 30 connecting the truss-shaped roof members 20 of the neighboring frame frames to each other and connecting the frame frames are arranged in a line. However, by the structural calculation, the braces 30 can be arranged in two or more rows so as to be spaced from each other at right angles to the longitudinal direction of the soundproof tunnel, and a vertical bracing (not shown) connecting the adjacent steel pipe columns 10 May be installed.
