Abstract

The present invention provides an additional base connecting material (4) to be installed when a rebar of a base structure (3) is placed instead of an embedded post. Moreover, a coupling rebar (4-2) is provided in the base connecting material (4) to be bonded with a main rebar (3-1), and a stud (4-3) protrudes to be attached to an internal floor surface of the base connecting material (4). According to the present invention, an embedded depth of a post can be significantly reduced, thereby innovatively and economically reducing a noise barrier material.

Description

[0001] The present invention relates to a post-insulator and a base-connecting system for a noise barrier,

BACKGROUND OF THE INVENTION Field of the Invention [0002] The present invention relates to an embedded column and a foundation connection part that are embedded in a lower foundation structure in a strut constituting a sound barrier wall, thereby improving support and connecting members to more efficiently and stably connect to the lower foundation structure, And an effect of reducing the amount of steel is obtained.

Generally, the sound barrier is installed at the edge of the road on which the vehicle is traveling, or in the vicinity of the center and the railway railroad, so as to attenuate, inhibit or prevent the noise generated from the running of the vehicle or train to neighboring houses or schools .

      This soundproofing wall is generally constructed by disposing the H-beam struts 1 at regular intervals on the underlying foundation structure 3 and installing a plurality of sound insulation boards 2 between the pillars 1, Generally, an anchor bolt is inserted in the upper part of the foundation structure to apply the anchor bolt coupling method to the foundation plate, The pillar-joint joining method is used in which concrete is installed by directly fixing the city pillar. The present invention relates to a sound absorbing structure of the above-mentioned support structure.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems occurring in a sound insulation wall of a quadriga fitting type which is a kind of conventional soundproof wall technology. In other words, the above-mentioned pillar-and-socket jointing method is more compact and more structurally stable than the anchor bolt connecting method. However, when the height of the sound barrier wall is increased, it is difficult to correct the construction errors that are increased, There have been disadvantages. In other words, when the strut is directly attached to the lower foundation structure, a slight error occurs vertically and horizontally in the process of fixing the strut to the foundation structure according to the design drawing. If the height of the soundproof wall becomes high, The more you go, the bigger it becomes. In order to prevent this, it is necessary to be careful in the initial fixing step according to the conventional method, and adjustment of the soundproofing plate is inevitable for the error that occurs afterwards. This is not only a disruption in the subsequent process and a decline in the economic efficiency, but also the problem of aesthetics. In addition, in the case of the strut which is to be embedded in the foundation structure, the surface of the strut is jointed by being welded so as to be confined to the cast iron root of the foundation structure, but the cast iron root and the strut are jointed by only point welding The horizontal strength is increased sharply when the height of the soundproof wall is increased. In order to smoothly support the horizontal strength, the number of the cast iron rods to be joined to the support should increase, but the cast iron rods are bonded to the flange width of the support. It is very uneasy because there are only two bonds in the cast iron root. In addition, there is an unreasonable requirement that the depth of the receiving stiffener must be increased so as to reach the depth of the bottom portion of the bottom portion of the foundation in order to secure the structural stability for continuously maintaining the designed stiffened portion before the concrete of the foundation struc- ture is installed come. This has been pointed out as one of the main reasons for avoiding the adoption of the holding buy-and-bond method because it causes economic loss. Accordingly, the present invention improves the pile support used in the pile-up coupling method and newly designes a separate foundation connecting member, so that the construction error caused by the increase of the soundproof wall can be easily corrected, and at the same time, So that the workability and economical efficiency can be greatly improved. In addition, the finished soundproofing wall greatly improves the resistance to external impact, thereby greatly improving the structural stability.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the above-mentioned prior art. To this end, the present invention has devised a base connector (4). That is, when the foundation connecting members 4 are installed together with the reinforcing bars of the foundation structure 3, the reinforcing supports 1 do not need to be embedded until the foundation structure 3 is finally completed, It becomes possible to avoid the unreasonable case of inevitably deeply ingesting to the foundation floor. In addition, the base connecting member 4 can be joined to the surrounding main steel rope 3-1 through the connecting reinforcing bar 4-2 so that the base connecting rod 4 can be stably and sufficiently bounded. A stud 4-3 is attached to the inner bottom surface of the base connecting member 4 so that the lower end of the inserted strut 1 is coupled to the stud 4-3, So that even if an unexpected upward force is generated, it can be fixedly fixed. Of course, in order to cope with this, the lower end of the inserted column 1 should have a fixing plate 1-2 having a stud hole 1-3 so as to be connected to the stud 4-3.

 In other words, the base connecting member 4 has a buried socket 4-1 having a pipe shape with a closed bottom and a stud 4-3 in the vertical direction on the bottom inner side. And a plurality of coupling bars 4-2 are attached symmetrically in the longitudinal direction of the sound barrier wall forward and backward. The studs 1-3 of the fixing plate 1-2 provided at the lower end of the inserted stanchion 1 are inserted into the embedded socket 4-1, So that the studs 4-3 are coupled with each other. Here, since the stud holes 1-3 are somewhat larger than the studs 4-3, the positions of the struts can be adjusted somewhat in the forward, backward, left, and right directions in the process of inserting the struts into the buried socket, It is possible to correct the error. In addition, a plurality of spacing washers 4-4 may be provided in the studs 4-3 to adjust the height error of the support by adjusting the number of washers.

On the other hand, the outer surface of the wall contacting with the cast iron rope 3-1 of the buried socket 4-1 is welded to the cast iron rope 3-1 by welding, and at the same time, 3-1 by welding so that finally the base connecting member 4 can be firmly integrated with the main steel rope 3-1 of the foundation structure. In this way, the foundation connecting member 4 is firmly integrated with the foundation structure, and the inner studs 4-3 can firmly fix the embedded struts so as not to fall upward. As a result, It is only required as much as the depth, but it does not need to overdo the land purchase depth. That is, the depth of the embedded strut is inserted directly below the depth of the upper cast iron root due to the base connecting member 4, which is firmly supported and joined to the foundation structure 3, That is, the minimum depth of about 300 to 500 mm is required at the top of the foundation structure, which is a remarkable saving effect of the holding steel compared to the level at which the foundation is purchased from at least 1000 mm to more than 3000 mm.

The present invention can be embodied by using a separate foundation connection material (4) having excellent structural stability and workability in a pillar-and-mortar connection system so that the pillar (1) can be embedded only to a minimum depth after the lower foundation structure (3) Therefore, it is possible to drastically reduce the depth of land purchase and thus achieve a remarkable economical effect of the soundproof wall material.

Particularly, the present invention is designed to easily correct a construction error such as a height and a horizontal position due to the increase of the sound barrier in the process of connecting the foundation link 4 and the support 1. Therefore, .

In addition, the finished soundproof wall will greatly improve the structural stability because the resistance against the external impact such as the impact of the vehicle, as well as the stability against the wind load, is greatly improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of a conventional strut-coupled joint-type soundproof wall, which is installed so that the strut 1 used in installing the soundproof wall is directly fixed at the time of assembling the reinforcing bars of the foundation structure 3, And finally the shape of the cross-sectional shape as shown in FIG. 1 is displayed through the process of installing the rear sound insulation plate 2. As shown in FIG. 5, since the coupling between the strut and the cast iron is accomplished only by tag welding at only a few points, the stability of the fixture can not be ensured. As a result, And is buried.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the above-mentioned prior art. 3, 4, and 6, a separate base connecting member 4 is designed to be stably and sufficiently bound to the cast iron of the foundation structure. In other words, the base connecting member 4 has a buried socket 4-1 having a pipe shape with a closed bottom and a stud 4-3 in the vertical direction on the bottom inner side. And a plurality of coupling bars 4-2 are attached symmetrically in the longitudinal direction of the sound barrier wall forward and backward. In this case, the embedded strut 1 is inserted into the embedded socket 4-1, and the stud hole 1-3 of the fixed plate 1-2 provided at the lower end of the inserted strut 1 is inserted into the stud hole 1-3, So that the studs 4-3 are coupled with each other. 7 shows how the fixing plate 1-2 having the stud holes 1-3 is coupled to the lower end of the landing pillar 1. As shown in Fig. Since the stud holes 1-3 are somewhat larger than the studs 4-3, the positions of the struts can be adjusted somewhat in the forward, backward, left, and right directions in the process of inserting the struts into the embedding socket. The position error can be corrected. In addition, a plurality of gap washers 4-4 may be provided on the studs 4-3 to adjust the height error of the supports by adjusting the number of washers. In FIG. 8, . In the present invention, the cross-sectional shape of the column 1 is generally H-shaped, but it may be modified into a rectangular pipe shape or various closed cross-section and open cross-sectional shape.

6, the outer surface of the wall contacting the cast steel 3-1 of the buried socket 4-1 is joined to the cast steel 3-1 by continuous row welding, and at the same time, (4-2) Also, the base connecting member 4 can be firmly integrated with the main steel rope 3-1 of the foundation structure by finally joining them by tag welding at a portion contacting the plurality of the main ropes 3-1. In this way, the foundation connecting member 4 is firmly integrated with the foundation structure, and the inner studs 4-3 can firmly fix the embedded struts so as not to fall upward. As a result, Only the depth is required, and it is not necessary to excessively embed the landing depth of the land. That is, due to the base connecting member 4, which is sufficiently rigidly supported and joined to the foundation structure 3, and at the same time, the foundation 1 is also strongly rigidly restrained, the depth of the support pillars is required to be at least a minimum depth, It is possible to obtain a significant reduction effect.
