DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

As shown in FIG. 9, the RCC dam 10 according to the present invention is constructed such that a PC panel 12 made of precast concrete is constructed on the upstream and downstream sides. 1 to 3, the PC panel 12 is formed in a plate-like shape having a predetermined thickness. The PC panel 12 may have a square or rectangular shape.

The PC panel 12 has panel-side pivot projections 121 and panel-side coupling edges 122 and 122 on four sides, respectively. The panel-side pivot protrusion 121 has an arcuate or semi-circular cross-section along the longitudinal direction of the side. The panel-side coupling edges 122 and 122 are formed symmetrically with the panel-side pivot projection 121 at the center.

The edge coupling socket 14 is coupled to an edge portion where the adjacent panels 12 and 12 meet. The edge coupling socket 14 is made of precast concrete. The edge coupling socket 14 serves to pivot to allow the PC panel 12 to be installed along the designed curved surface of the RCC dam 10, while simultaneously inducing coupling between the panels 12 and 12.

As shown in FIGS. 4 and 5, the edge coupling socket 14 is configured to be smaller than the side length of the PC panel 12. The edge coupling socket 14 has an edge socket side engagement groove 141 pivotally coupled to the pivot projection 121 of the PC panel 12 for pivotal engagement with the PC panel 12, And has edge-socket-side coupling edges 142 and 142 symmetrically formed on both sides in the longitudinal direction to be coupled with the coupling edges 122 and 122. [ At this time, as shown in FIG. 4, the gap G is provided between the panel-side coupling edges 122 and 122 and the edge-socket-side coupling edges 142 and 142 so that the curved surface of the PC panel 12 can be arranged. This clearance G facilitates the curved surface arrangement of the PC panel 12 by causing a tilting angle [theta] according to the pivotal movement of the PC panel 12 coupled to the edge coupling socket 14. [ This clearance G can be determined within a range in which the angle adjustment of the PC panel 12 is performed within a range of 5 DEG to 10 DEG.

As shown in FIGS. 1 and 3, a cross coupling socket 16 is provided at an intersection where the four PC panels 12 intersect with each other. The cross coupling socket 16 is made of precast concrete. The cross coupling socket 16 enables the simultaneous construction of the upper and lower curved surfaces and the left and right curved surfaces of the RCC dam 10 by joining the intersections of the four PC panels 12.

As shown in FIG. 6, the cross coupling socket 16 has a cross-socket-side coupling groove 161 that is engaged with the panel-side pivot projection 121 of the PC panel 12 on a circumferential surface in a cross shape, Side-side coupling edges 162 and 162 that are engaged with the panel-side coupling edge 122.

Thus, the RCC dam 10 is pivotally coupled to the adjacent panels 12 and 12 via the edge-coupling socket 14, and the PC panels 12 are pivoted in the cross- The coupling is made at the intersection where it meets.

Accordingly, as shown in FIG. 9, the downstream surface of the RCC dam 10 is not only capable of curved surface construction in the vertical direction, but also can be curved in the lateral direction. In the case of the left and right direction, it can be configured to be convex to the center or to be concave. In this way, the RCC dam 10 can follow the designed curved surface to construct the PC panel 12, so that the RCC dam 10 can have an aesthetic appearance.

The panel angle adjusting anchor assembly 20 is connected to the rear side of each PC panel 12 in order to adjust the angle of the curved surface of the PC panel 12 during the construction of the PC panel 12. The panel angle adjusting anchor assembly 20 is hingedly connected to two or more places on the back surface of the PC panel 12. [

7, the panel angle adjusting anchor assembly 20 includes a panel side rod arm 21 having a predetermined length hinged to the back surface of the PC panel 12, An anchor side rod arm 23 having one end screwed to the other end of the turn buckle 22 and an anchor side rod arm 23 fixed to the other end of the turn buckle 22, And an anchor (24) connected to the other end of the side rod arm (23) and embedded in the dam concrete for installation in the site. At this time, the coupling arm 25 may be further connected to the rod arm 21. [

2, the overall length of the panel angle adjusting anchor assembly 20 is increased or decreased in accordance with the rotation direction of the angle adjusting turn buckle 22 in a state where the anchor 24 is fixed to the concrete for dam construction, So that the angle of entry of the PC panel 12 can be adjusted to follow the designed curved surface of the RCC dam 10.

As shown in FIG. 4, a waterproofing material 30, which is closely fitted between the panel-side coupling step 122 and the edge-socket-side coupling step 142 for waterproofing the inner surface of the downstream side of the RCC dam 10 to be constructed, Can be installed. The waterproofing material 30 may be made of a soft plastic such as PVC or urethane. The waterproofing material 30 has a waterproof tight contact portion 301 which is forcibly contracted and deformed as shown in Fig. 8 and a retaining jaw 302 for restricting the insertion of the waterproof tight contact portion 301. The waterproof adhered portion 301 may further include a hollow hole 301a in order to increase the elastic repulsive force.

The construction method of the RCC dam thus constructed will be described.

First, as shown in FIG. 1, the panel foundation 5 is formed on the bottom side of the dam to be installed so that the filler filling grooves 5a are formed on the upper surface as shown in FIG. The panel base (5) is placed in the space of the concrete and panel foundation (5) and is constructed of reinforced concrete which is synthesized in concrete. The width of the filling material filling groove 5a is formed larger than the thickness of the PC panel 12 to be described later.

Then, the PC panel 12 constituting the upper and lower surfaces of the dam is fitted into the filler filling grooves 5a of the panel foundation 5 and filled with the filler 6 at regular intervals from each other. The filler 6 may be a mortar mixed with water and cement. Thus, a single-stage panel is constructed.

At this time, the RCC dam can construct the PC panel 12 of the present invention both on the upstream and downstream sides. However, in order to construct only the downstream surface of the downstream side where the contour is revealed to the outside, And the PC panel 12 of the present invention may be installed only on the downstream side.

A panel angle adjusting anchor assembly 20 connected to the rear surface of the PC panel 12 by a panel side rod arm 21, an angle adjusting turn buckle 22, an anchor side rod arm 23 and an anchor 24, .

Then, concrete for dam construction 8 is poured into a space between the upper and lower surface side panels 12 and 12 at a predetermined height.

Then, the panel panel 12 is connected to the same PC panel 12 from the one-end PC panel 12, and the connection of the panel angle adjusting anchor assembly 20 and the concrete for dam construction are repeated. At this time, 1 and 11, the cross-coupled socket 16 is coupled to the intersection where the adjacent panels 12 and 12 cross each other at the same time, and at the same time, .

Of course, at this time, the angle adjusting angle of the PC panel 12 is adjusted by operating the turn-adjusting buckle 22 of the panel angle adjusting anchor assembly 20 so as to follow the designed curved surface.

A joint is formed between the edge of the PC panel 12 and the edges of the edge coupling socket 14 and the cross coupling socket 16 by filling the gap between the edges.

At this time, it is needless to say that a waterproof material 30 made of a soft plastic such as PVC or urethane may be further provided between the gap between the PC panel 12 and the edge coupling socket 14 as the inner wall of the downstream surface.

The RCC dam 10 thus constructed is pivotally coupled to the adjacent panels 12 and 12 through the edge coupling socket 14 and is connected to the PC panels 12 through the cross coupling socket 16. [ Bonding occurs at the intersection where the cross is encountered. In addition, the angle of the PC panel 12 can be adjusted by adjusting the angle of the panel angle adjusting anchor assembly 20, so that the arch curved surface can be formed, and the aesthetic appearance can be improved.

In the present invention, the edges (h1 and h2) of the edge-socket-side coupling edges 142 and 142 of the edge-coupling socket 14 may be different from each other as shown in FIG. In this case, the PC panel 12 is arranged to be inclined in a relatively low height direction, thereby making it possible to form an irregular surface of the RCC dam.

The present invention also includes a socket body 14a having an edge socket side engagement groove 141 to be engaged with the pivot protrusion 121 as shown in Fig. 13 and a socket body 14a having a soft plastic Socket blades 14b and 14b which are manufactured on the both sides of the socket body 14a and joined with the panel side coupling edges 122 and 122 to have different heights h1 and h2 and the socket blades 14b and 14b which are inserted into the socket body 14a, And a wing bridge 14c connecting the wings 14b and 14b. At this time, the wing bridges 14c are made of the same material as the socket wings 14b and 14b and integrated. Each of the socket blades 14b and 14b may have a plurality of air pockets 14d in order to increase elastic repulsive force.

In this case, the edge coupling socket 14 prepares the socket body 14a with precast concrete, and thereafter injects soft synthetic resin into the socket body 14a from the mold to form the socket wings 14b and 14b and the wing bridge 14a. (14c) are integrally molded.

In the present embodiment, the socket blades 14b and 14b are formed with h1 > h2, and the PC panel 12 is arranged to be inclined in the h2 direction.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be.
