In general, in order to build a building on a soft ground or to carry out various civil works, it is necessary to reinforce the ground first.In order to reinforce the soft ground, it is often necessary to lay a top pile on which the concrete is loaded to lay the ground. Do construction.

The top pile is composed of an inverted triangular pyramidal shape having an upper end opening so that concrete can be loaded therein, and a pile part supporting the support at the bottom of the support and having a pointed bottom In consideration of manufacturability and workability, it is mainly made of synthetic resins and various forms thereof. For example, the present applicant has devised various types of formwork for folding piles, and the Republic of Korea Patent Registration No. 10-0469143, Patent Registration No. 10- 0500599 and the like.

When explaining the basic construction method of the conventional soft ground using the top pile as follows.

First, the plurality of top piles are installed to be connected to each other horizontally and longitudinally, and then the tops of all top piles are tied together by fixing the two interconnected top piles together using a bundle means such as cable ties, wires, and strings. Top connection process), and reinforce the basic rebar in the horizontal and / or longitudinal direction to the neck of the top pile, and fix the basic rebar and the basic rebar by fixing means such as cable ties, wires, strings or welding. By this, the top panel is assembled (tie binding and top panel assembly step).

Subsequently, after the surface of the soft ground is evenly applied, a civil engineering mat such as a nonwoven fabric is applied on the ground (civil engineering mat installation process), and a plurality of the assembled top panels are successively installed on the mat (top panel installation process). .

When the top panel is installed, concrete is filled in each top pile (with concrete consolidation process), and a top ring is installed at the center of each top pile before the concrete is hardened (a top hook installation process).

When the concrete is hardened to some extent (curing process), it is left in this state for about 1 to 3 days to fill the crushed stone in the space formed between each top pile and compact it to distribute it evenly and uniformly in all spaces (aggregate filling and After the compaction process), connecting the reinforcing bar to each of the protruding ponchos and binds, whereby connecting by a bundle fixing means such as cable ties, wires or strings (connecting reinforcement and tie-binding process), and thus produced The concrete is laid on the top panel to be cured to form the foundation concrete layer (base concrete laying process) to complete the construction of the foundation pile. The ready-mixing process of injecting and filling the ready-mixed concrete into the top pile includes the following problems: .

First, because the top pile is open top and mostly circular, the top of the top panel is very inconvenient and somewhat dangerous when the worker moves on it because the space that the operator can step on is very limited.

Second, since the ready-mixed concrete leaks into the space between the top panels, there is a problem in that the lost concrete is discarded without being introduced into the top pile.

Third, the worker's load is concentrated on a part of the top file, and a problem arises that the top file is damaged by the hitting of ready-mixed concrete.

Accordingly, the present invention for solving the above problems, while preventing the ready-mixed concrete leaks into the space between the top piles during the ready-mixing process, allowing the operator to move the top of the top panel safely and conveniently, at the same time It is an object of the present invention to provide a concrete pouring plate of the field-pouring top pile to prevent the damage and the construction method using the same.

The top pile 110, the upper surface is open so that the concrete is introduced into the filling is wide, the upper side is wider or narrower toward the bottom (上 廣 下 狹) shape, or inverted triangular pyramid shape It is formed with a support portion 111 and downwardly integrally formed downward from the lower portion of the support portion 111 and the lower end is composed of a sharply formed pile portion 112 to facilitate insertion into the ground, so If the file 110 has a support part 111 and the file part 112, the shape such as a circle or a polygon may be variously modified from a plan view point of view. It is also possible to apply the invention with reference to the proposed ones.

On the other hand, as shown in the example shown in Figure 1, the four horizontally and vertically, or in the longitudinal and transverse direction to install each four in succession, in order to mutually secure each of the neighboring interconnected piles, The connecting reinforcing rods 120 pass through the inclined surface of the buoys 111 of the respective top piles 110 to integrate a plurality of top piles 110 to form one assembly.

In this case, the portion where the connecting reinforcing rod 120 penetrates is preferably an inclined surface of the top pile 110, and furthermore, each top pile 110 connected to each other at the time of carrying or installing the top panel 100 by penetrating the center of gravity. It is desirable to have no top or flow of the top of.

In addition, the connecting reinforcing rods 120 are disposed in the horizontal and vertical directions, respectively, so that the connecting reinforcing rod 120 penetrates in a cross shape with respect to one of the top piles 110. It is firmly secured to each other and does not need to be secured by separate binding means (wire, tie, string, etc.).

However, the present invention is not limited thereto, and the top and bottom sides of the top pile 110 can be varied, and the length of each side of the top panel is 1 m. The number may be increased or decreased within the range of from 4 m to 4 m.

Thus, the top panel 100 in which the plurality of top piles 110 are assembled is coupled in a state in which the top piles 110 are connected to each other, but a space 115 exists between the top piles 110. Since the space 115 is necessary in the aggregate filling process (S70), which will be described later, a certain size should be maintained, and as shown, when the circular top pile 110 is assembled, the top of the space 115 is rhombic. Has the shape of.

As the injection hole 131 is shown as a round perforated, or includes a polygon, such as a rectangular, hexagonal and all, but the diameter must be smaller than the inner diameter of the top of the top pile 110 This is because if the inner diameter of the injection hole 131 is equal to or larger than the outer diameter of the top pile, the pour plate 130 is not stacked on the top panel 100 and falls into the space 115.

As another preferred form of the pour plate 130, the handle 132 is provided at the edge to be used when the pour plate 130 is transported or moved in position on the top panel 100, the transverse of the injection hole 131 And the number of longitudinal direction does not necessarily have to match the number of transverse and longitudinal direction of the top panel, but can be configured arbitrarily, it is to be in the range of 2 to 10 in the transverse and longitudinal direction respectively in consideration of transport or workability. desirable.

5 is a cross-sectional view showing a ready-mixed concrete placing process (S50) according to the present invention, the ready-mixed concrete placing process (S50) with reference to FIG. 5, each top pile 110, the ready-mixed concrete (5) supplied from the ready-mixed vehicle or the ready-mixed concrete supply device As a process of injecting and filling into the internal space of the above, as described above, a skilled worker directly climbs on the top panel 100 to hold the ready-mixed concrete inlet pipe 5a and moves the topped pile 110 while injecting ready-mixed concrete. However, in this case, the workability is poor and the top pile 110 is broken, and the ready-mixed concrete 5 was leaked into the space 115 to waste the ready-mixed concrete, but when the pour plate 130 is installed as in the present invention, Since the operator can move the pour plate 130 in a relatively large area, the mobility is improved and workability is improved accordingly, and the pour plate 130 distributes the load concentrated in the stepping position. Top file 110 does not become damaged.

Moreover, since the pouring plate 130 blocks the space 115 as shown in FIG. 4, the ready-mixed concrete 5 is injected into the top pile 110 through each injection hole 131 without leaking. Even if the injection amount is excessive, the overflowed ready-mixed concrete (5) will be on the pour plate, so that it may be injected into the other top pile around.

FIG. 6 is a cross-sectional view illustrating a step of installing a claw in accordance with the present invention (S60). As shown in FIG. 6, when the injection of the ready-mixed concrete 5 is completed, the entangled ring 6 having a 'U' shape is encapsulated. Installed on top of the pile 110, the top pile (6) is one of each of the 'U' shaped end is long and one has a short structure.

The installation direction of the enclosed ring 6 is inverted 'U' shape is installed so as to protrude a certain height upward from the top of the top pile 110, the protruding height is satisfied 4 to 6cm, but is not limited thereto.

When the concrete 5 is cured to some extent by curing the ready-mixed concrete 5 to 1 to 3 days, the reinforcing bar 6 may be used to reinforce the connecting reinforcing bar (not shown), and then the pouring plate 130 may be used. Is removed so that the space 115 is exposed.

When the crushed stone 7 is filled to some extent when the crushed stone 7 is filled, the crushed stone 7 is sufficient in the space 115 by pulverizing the inside with a vibrator (not shown) and further injecting the crushed stone 7. It is preferable to carry out operations such as filling to a uniform density and flattening the machined portion where the crushed stone 7 protrudes from the top of the top pile 110 by using a machine.

8 is a cross-sectional view showing the step of laying the foundation concrete layer according to the present invention (S80), after the installation of the ground foundation structure using the top panel 100 is completed, by laying concrete with a certain thickness on the top panel 100 When cured, a base concrete layer 8 having a constant thickness is formed as shown, wherein the connecting ring 6 is embedded in the base concrete layer 8 so as to be firmly bonded to the base concrete layer 8. have.

As described above, according to the present invention, the space between the top piles is closed by the pouring plate during the ready-mixing process, and the injection hole opens only a part of the opening of each top pile, as well as the effective space that an operator can take. Because of this widening, it is possible to prevent the ready-mixed concrete from leaking into the space. Even if the injection into the top pile is excessive, the overflowed ready-mixed concrete can be re-injected into the surrounding top pile to eliminate the leakage loss of the ready-mixed concrete. And it can move the top panel conveniently and has the effect of improving workability.

Moreover, the pour plate disperses the load of the operator so that it is not concentrated at the stepping position of the top pile, and also prevents the top pile from being damaged by preventing the ready-mixed concrete discharged at high speed from the guide pipe directly hitting the top pile. As a result, it is a very improved invention that can significantly shorten the construction period, improve workability, and innovatively reduce construction costs.
