Description

TECHNICAL FIELD [0001] The present invention relates to a profiled integral-type indexer for a floating slab, a floating slab structure using the profilometer, and a method of constructing the same.

The present invention relates to a profiled integral profilometer for a floating slab, a floating slab structure using the same, and a method of constructing the same. More particularly, the present invention relates to a profilometer for cutting a flow of water between a floating slab for a railway track, And a floating slab structure using the same.

In recent years, the importance of railways in transportation has become more and more important due to stability and accuracy. In addition, demand for urban railways and trains is increasing as part of the efforts to overcome traffic congestion in the city, and railway utilization and convenience are gradually increasing due to the opening of railway lines passing through urban areas and adjacent buildings.

However, due to increased noise and vibration due to the increase in the speed of the train, civil complaints are increasing, resulting in various problems such as deterioration of the usability of the structure and exceeding the environmental standard value related to noise and vibration.

In order to solve these problems, various methods such as application of a vibration pad have been tried. Among them, a floating slab track is installed in a state separated from the ground by a vibration pad or the like, .

The floating slab track is installed on the upper surface of the ground by making a concrete slab through which a train passes and is made of a precast concrete slab, and a vibration pad, a spring or a damping member is inserted between the ground and the slab to prevent noise and vibration .

1, the floating slab track 10 is divided into an upper slab track 11 and a lower slab track 12 which are seated on the upper surface of the ground 1, An index material 20 is provided between the lower slab track 12 and the lower slab track 12 so that no rain penetrates from the upper slab track 11 to the lower slab track 12. [

 Since the rainwater infiltrating into the lower part of the slab track 10 becomes high on the interface with the ground, it causes problems such as corrosion of the reinforcing bars in the concrete or expansion upon freezing to destroy the slab itself, It is very important to ensure that the storm does not penetrate through.

Generally, the floating slab track 10 is constructed by arranging a plurality of precast concrete slabs in a row. The upper surface between the slab and the slab is spaced apart by a predetermined distance to form a gap 13.

The gap 13 between the slabs is spaced by a predetermined distance in advance against the expansion of the slab made of concrete by the solar heat. The upper surface of the gap 13 is provided with a profiler 30 ).

The profiler 30 is constructed of a steel plate and is fixed to the upper surface of the gap 13 between the slabs by a bolting operation, thereby shielding the gap 13 between the slabs.

However, in the conventional floating slab track, the exponent and the profiler have to be installed separately, which complicates the process and increases the construction period.

In addition, since the profiler can not perfectly shield the gap between the slabs, there is a problem that a large amount of rainwater penetrates therebetween, thereby failing to cut off the rainwater despite the index re-installation.

FIG. 2 shows a preferred embodiment of a profiled integral type indexer for a floating slab according to the present invention and a floating slab structure using the same. As shown in the figure, the integral type index body 100 of the present invention includes a main body 110 formed between a slab and a slab; A horizontal plate 120 extending horizontally at a middle portion of the main body 110 and a profiler head 130 formed at an upper end of the main body 110. [

The main body 110 may be formed of a synthetic resin such as polyvinyl chloride (PVC). The main body 110 may have a double plate structure in which two plates are spaced apart from each other by a predetermined distance to form a hollow 111 therein. do.

Since the main body 110 is formed in a double plate structure in which a hollow is formed therein, when the surrounding concrete slab thermally expands, the main body 110 is compressed in the hollow direction to serve as a buffer, and the concrete slab And may be configured to return to its original shape by its own elastic force when it is cooled.

A horizontal plate 120 extending in the horizontal direction is formed integrally with the main body 110 at an end of the main body 110. The horizontal plate 120 is formed in a horizontal plate shape, and a plurality of ribs 121 are formed at regular intervals on the upper surface or the lower surface of the horizontal plate 120.

The horizontal plate 120 and the plurality of ribs 121 form a long channel for water flowing in the direction of the lower slab from the upper slab so as to block water flowing into the lower slab.

At the upper end of the main body 110, a profiler head 130 for blocking a gap between the slab and the slab is formed. The profiler head 130 is formed in a double plate structure having a hollow inside as in the main body 110. The top surface of the profiler head 130 is flat and the gap between the slabs is horizontally closed.

That is, the profiler head 130 includes two swash plate parts 131 and a top plate part 132 connected to the upper ends of the swash plate parts 131. Thus, the profile of the profiler head 130 is formed in an inverted triangular shape as shown in FIGS.

3 shows another embodiment of the profiled integral type index body for a floating slab according to the present invention. As shown in the figure, the index body 100 according to another embodiment is formed with at least one incision 133 in the upper plate portion 132 of the profiler head 130. The incision 133 is intended to cause the thermal expansion of the peripheral slab to cause the profiler head 130 to be pressed downward without protruding upward when it is compressed.

The upper plate 140 of the profiler head 130 may be connected to the upper plate 132. A fastening protrusion 141 is formed on the lower surface of the upper plate 140. The fastening protrusion 141 is inserted into a fastening hole 134 formed in the upper plate 132 to be fastened to the profiler head 130. [ have.

The upper plate 140 serves to keep the slabs flat even when the profiler head 130 is squeezed. That is, as shown in FIG. 4A, the upper plate 140 is connected to the upper surface of the profiler head 130 to cover the gap between the slabs. 4B, when the slab expands and the gap between the slabs is reduced, the profiler head 130 is squeezed and folded down along the incision 133, so that the upper plate portion 132 of the profiler head 130 is folded down, .

At this time, since the upper plate 140 connected to the upper plate 132 maintains flatness, it is possible to prevent the formation of pits in the gap between the slabs.

Hereinafter, a method of constructing a floating slab structure using a profiled integral type index element for a floating slab according to the present invention will be described in detail with reference to FIGS. 5A to 5F.

First, as shown in FIG. 5A, after a compaction process is performed on a foundation foundation 200, an anti-vibration member 210 is installed on an upper surface of the foundation foundation 200. The anti-vibration member 210 is not limited to any one type and may be configured in various forms.

5B, a lower slab 310 made of precast concrete slab manufactured on the upper surface of the anti-vibration member 210 is installed. A plurality of the lower slabs 310 are connected to each other, and the lower slabs 310 connected to each other are spaced apart from each other by a predetermined distance so that the index body 100 of the present invention can be inserted into the spaces therebetween.

Then, as shown in FIG. 5C, a thin layer of mortar 311 is laid on the upper surface of the lower slab 310. Before the mortar 311 is cured, the index body 100 of the present invention is inserted and fixed between the lower slabs 310 as shown in FIG. 5D.

When the index body 100 is fixed between the lower slabs 310 as described above, the formwork 320 is installed. At this time, since the index body 100 of the present invention serves as a covering film at the interface between the slab and the slab, it is not necessary to additionally provide the formwork 320 in this part, so that the time for producing the formwork can be reduced.

After the form 320 is installed as shown in FIG. 5E, an exponent liquid spraying operation may be further performed on the surface of the exponent 100 before the concrete is poured. The index solution improves adhesion with concrete to be laid on the surface of the index body 100, and also prevents water from penetrating through the interface between the index body 100 and the concrete.

When the exponent liquid is sprayed, after the concrete is poured, the curing process is performed for a predetermined period, and then the form 320 is disassembled, the floating slab structure is completed. After completion of the finishing process, the railway rail track is completed.

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 and scope of the present invention as defined by the following claims It can be understood that
