Description

Roof type soundproofed wall with reinforcing tendon}

The present invention relates to a soundproof wall installed in a noise source area, in particular, to support the load on the loop side with a tension structure to reduce the burden of the dominant load acting on the support to prevent deformation of the support and to reduce the size of the support cross section The present invention relates to a loop-type soundproof wall reinforced with tendons that can reduce construction costs.

According to the road and residential environment, the height of the soundproof wall is increasing, but the installation height of the soundproof wall structure is bound to be limited. In addition, the soundproofing tunnel has the highest soundproofing effect, but there are difficulties in construction such as excessive control costs and traffic control issues for roads in transit. Therefore, as an alternative to these problems, there is a demand for a loop-type or canopy-type soundproof wall in which beams are installed in one road direction or both road directions at the top of the soundproof wall support.

In general soundproof walls, the transverse wind pressure is the dominant load, but in the case of the loop type, the snow load along with the wind load can be the dominant load, and the dead load is a load directly on the member. In addition, in order to ensure the stability and usability of the sound insulation board installed in the roof part, the vertical deflection of the roof part due to wind load and snow load should be examined according to the design criteria.

In the design of the loop type soundproof wall or soundproof tunnel, tension members by beams or wire ropes are installed to vertically deflect the loop part members. However, all of these beams or tension ropes, which are reinforced in the loop support member, are fixed to the support or install a separate structure for fixing the tension member. Therefore, when fixing to the support, deformation between the loop support member and the support can be controlled. However, since the load is fully applied to the shore, the displacement of the shore itself cannot be controlled, and excessive displacement still occurs in the loop support member. And fixing to a separate structure is a burden on the addition of the structure.

Korean Patent No. 10-0495712 is a soundproof plate that is rotated when the external force generated in the front and rear sides by the hinge shaft provided at both ends between the support and the support, the rotary cam is provided at the end of the hinge shaft and rotated together with the hinge shaft ; A lower end portion is hinged to a fixing member provided inside the outer frame at an inner side of a soundproof plate fixing outer frame which is fixed to the support, and one end of which is hinged to an outer end of the rotating cam to rotate the rotary cam. A cylinder having a piston rod which is moved back and forth during the vehicle; It is provided inside the cylinder has an elastic force when the pulling force of the piston rod is compressed and the elastic spring to return to the initial state when the pulling force is released; 'rotating soundproof plate having elastic return force' characterized in that it comprises a Presented. This means that when excessive wind pressure is generated on the soundproof wall, the soundproof plate is elastically rotated by the elastic force of the elastic spring to absorb the wind pressure, and at the same time, the soundproof plate is quickly restored to the initial state by the restoring force of the elastic spring to maintain the upright state of the soundproof panel. . However, Patent Document 1 proposes a solution for wind pressure, but does not suggest a solution for snow load in a loop type soundproof wall. In Korean Patent No. 10-0622022, the prop is placed on the edge of the road in the soundproof section; Sound absorbing soundproof plate laminated in the vertical direction on the support; A horizontal support fixed to the top of the soundproof board in a cantilever shape and supported by the support by a support means and extending toward the driveway; Sound absorption and sound insulation roof panel is installed on the horizontal support made of an ultra-light composite material; And support the wind pressure control door which is hinged to the roof panel to be openable and close to the roof panel and is opened when the wind pressure exceeds the set pressure, and closed by self-weight, and the shock caused by the opening of the wind pressure control door is transmitted to the soundproof wall fixing structure. A 'loop type sound barrier structure' is provided which comprises means. However, in Patent Document 2, when excessive snow load acts on the roof panel, a bending moment is generated in the pillar, and a bending displacement occurs, and the roof panel also sags in the vertical direction, and thus it is difficult to exert a function as a soundproof wall. In order to solve this problem, it is necessary to increase the cross section of the pillar.

Therefore, the present invention can prevent the deformation of the struts by reducing the burden of the dominant load acting on the struts by supporting the load on the loop side with the tension structure in the soundproof wall installed in the cantilever shape, and can reduce the size of the strut cross section to reduce the construction cost.
