Construction structure and method of RC wall integrated with finish panel

The present invention relates to a construction structure and a construction method of reinforced concrete walls uniting reinforced concrete concrete construction and finishing work, and more specifically, the finished integral reinforced concrete walls that maximize the stability in construction without damaging the appearance of the finishing panel. Construction structure and construction method.

Usually after the concrete construction of the reinforced concrete structure to perform the finishing work in a separate process to make the appearance beautiful. Concrete construction of reinforced concrete structures is usually carried out by a wet method on site, and finishing works are performed by connecting steel, adhesive, mortar, etc. to finish panels (brick, stone, tiles, etc.) on the finished concrete surface. It is common to proceed while attaching.

1 is a view showing an example of finishing with a stone panel on the front surface of the reinforced concrete retaining wall by a conventional method, and as shown in the related art, once the reinforced concrete retaining wall concrete is constructed, the anchor nails are anchored on the retaining wall surface. It has been constructed by connecting the nail and the stone panel with a connecting wire to adjust the position of the stone panel and then filling mortar between the stone panel and the retaining wall sphere. However, this method implies that the construction period is delayed according to the progress of concrete construction and finishing work, and it is not only cumbersome to work on anchor nails, but also in the process of anchoring nails. The loss of strength is a concern, and furthermore, the durability of the connecting wire and mortar is easily degraded, and thus the stone panel is easily dropped.

In order to improve the above problems, a finish-type wall construction method as shown in FIG. 2 has been proposed. 2 is a method of finishing the integral wall construction method of installing the prefabricated panel with the finishing material as the outer wall formwork and then tightening it to the wall reinforcement or the wall formwork, and then pouring the wall concrete to proceed with the finishing work and the reinforcement. Since concrete concrete work is unified, construction costs can be reduced while reducing air. However, this method has a limitation that it can be applied only when the prefabricated panel to which the finishing material is attached is provided with a considerable thickness so as to have a substantial strength. This is because the prefabricated panel with the finishing material should be the outer wall formwork so that it can withstand the lateral pressure during concrete placement.

The present invention was created in order to improve the above-mentioned conventional problems, while unifying the finishing work and reinforced concrete concrete construction, while adopting a thin thickness finishing panel, it is possible to maximize construction stability and further damage the appearance of the finishing panel. There is a technical problem in providing a construction structure and a construction method of the one-piece reinforced concrete walls that can be prevented.

In order to solve the above technical problem, the present invention provides a construction structure of the integrally integrated reinforced concrete wall as a construction structure of the reinforced concrete wall closed with a finishing panel, the outer support frame; A closing panel fixedly installed at the inner side of the outer support frame by a fastener and provided with a plurality of finishing panels facing up, down, left and right; A wall reinforcing bar constructed to be located inside the finishing panel and having horizontal bars and vertical bars assembled; A plurality of long support rods fixed to the finishing panel and installed to be constrained to the wall reinforcement; An inner wall formwork constructed to be located inside the elongated support rod and constructed so as to be connected to the elongated support rod or to be self-supporting; And a wall concrete that is poured between the finishing panel and the inner wall formwork.

A fastener for fixing the closing panel to the outer support frame, the locking pieces being installed at the positions where the finishing panels are opposed to each other to the inner side of the finishing panel and are simultaneously disposed to overlap the adjacent finishing panels; A fixing piece installed on an outer surface of the outer support frame as a position corresponding to the locking piece; And a connecting piece for connecting and engaging the locking piece and the fixed piece while passing between the facing surfaces of the adjacent finishing panels facing each other.

In addition, the present invention provides a method for constructing a reinforced concrete wall finished with a finishing panel, comprising the steps of: (a) installing an outer support frame outside the finish line of the reinforced concrete wall to be constructed; (b) a step of fixing the inner side surface of the outer support frame while fixing the up and down left and right buttling the finishing panel is fixed to the inner support rod fixed to the inner side; (c) reinforcing wall reinforcing bars in which horizontal and vertical bars are assembled into the finishing panel; (d) restraining the tight support rods fixed to the finishing panel to the wall reinforcing bars; (e) installing an inner wall formwork to the inside of the long support rod, and installing the unit to be self-supporting or freestanding to the long support rod; (f) placing wall concrete between the finishing panel and the inner wall formwork; And, (g) removing the outer support frame and the inner wall formwork;

The step (b) is a locking piece which is installed so as to overlap the adjacent finishing panel at the same time in a portion where the closing panel inner surface of the closing panel is opposed to each other, and installed on the outer side of the outer support frame as a position corresponding to the locking piece The fixing panel is configured to be fixed to the inner side of the outer support frame by a fastener configured to include a connecting piece for connecting and fastening the engaging piece and the fixing piece while passing between the mating surface of the adjacent closing panel facing each other. Provides a method of construction of the one-piece reinforced concrete wall characterized in that.

According to the present invention, the following effects are expected.

First, the reinforcement concrete and finishing works will be unified, which will lead to shortening of air-conditioning and construction costs, as well as suppression of falling-off panels. In particular, since the finishing panel is installed to receive the support of the outer support frame, it is possible to proceed with the construction of the reinforced concrete wall in the form of a finish while applying a thin thickness finishing panel.

Second, since the outer support frame and the finishing panel are mutually bound through the gap between the finishing panels by using a fastener composed of a locking piece, a fixing piece, and a connecting piece, the exterior of the finishing panel is provided even when the outer supporting frame is provided outside the finishing panel. It is possible to complete the finished reinforced concrete walls without damage.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

Figure 3 and Figure 4 shows the construction structure of the finished integrally reinforced concrete wall according to the present invention, as shown in the present invention is fixed to the inner side surface of the outer support frame 10 as a fixing panel 20 as a fixture 100 At the same time it is characterized in that it is connected to the reinforcing bar 40 with the long support rod 30.

Specifically, the present invention, the outer support frame 10; A closing panel 20 fixedly installed at the inner side of the outer support frame 10 by a fixture 100 and installed so that a plurality of upper and lower sides of the support frame 10 are connected to each other; A wall reinforcing bar 40 constructed to be positioned inside the finishing panel 20, wherein horizontal reinforcing bars and vertical reinforcing bars are assembled; A plurality of long support rods 30 which are installed to be fixed to the finishing panel 20 and restrained to the wall reinforcement 40; An inner wall formwork 50 which is constructed to be located inside the tension support rod 30 but constructed to be tightly coupled to the tension support rod 30 or to be self-supporting; And wall concrete 60 which is poured between the finishing panel 20 and the inner wall formwork 50.

The outer support frame 10 supports the finish panel 20 and at the same time serves to support the side pressure during concrete pouring with the finish panel 20. As the outer support frame 10, it is also possible to adopt a frame frame composed of a horizontal bar and a vertical bar assembly, it is also possible to adopt the outer wall formwork commonly used for wall construction as it is.

The outer support frame 10 does not need to provide a separate brace for supporting the outer support frame 10 because the tight support rod 30 fixed to the finishing panel 20 is restrained by the wall reinforcement 40 If the brace is installed, it is more advantageous in terms of construction stability.

Closing panel 20 is installed so as to be connected to a plurality of up, down, left and right but is installed to be fixed to the inner side of the outer support frame 10 as a fixture 100, in the present invention is fastened as shown in FIG. A fixture 100 including a piece 110, a fixing piece 120, and a connecting piece 130 is proposed. The locking piece 110 is a configuration that is installed so as to overlap the adjacent closing panel 20 at the same time in the finishing panel 20 to the mutually facing position on the inner side of the finishing panel 20, the fixing piece 120 Is a configuration corresponding to the locking piece 110 is installed on the outer surface of the outer support frame 10, the connecting piece 130 is a portion of the finish panel 20 butt next to each other that is adjacent to each other finish panel It is a structure which connects and binds the said engaging piece 110 and the fixed piece 120 mutually, while passing the clearance gap between the opposing surfaces of 20. As shown in FIG. As shown in FIG. 4, the locking piece 110 may adopt a plate member or a bar type member, and the connection piece 130 may employ an iron wire. Fixture 100 of this configuration is because the outer support frame 10 and the closing panel 20 through the gap between the closing panel 20 mutually the appearance of the finishing panel 20 (the outer outer support frame is removed in the future) So that the exposed outer portion of the finishing panel) is not damaged. Since the finishing panel 20 is fixed to the outer support frame 10 by the fastener 100 and is supported by the outer support frame 10, the finishing panel 20 may be thin.

In addition, the finishing panel 20 is installed so that a plurality of up, down, left, and right facing each other, in this case, it is preferable that the finishing panel 20 is mutually joined with a filler (22, adhesive, mortar, etc.). This is to prevent the appearance damage of the finish panel 20 by preventing the leakage of moisture generated during the curing process of the wall concrete 60, in particular to prepare the groove 21 is processed on the mating surface with the finish panel 20 If the rear panel 20 is joined back to each other with the filler 22, the effect of preventing water leakage will be further increased.

The wall reinforcing bar 40 serves as a main reinforcing bar of the reinforced concrete wall to be constructed as the horizontal reinforcing bar and the vertical reinforcing bar are assembled, and are constructed to be located inside the finishing panel 20. Since the wall reinforcement 40 is fixed to the foundation (or floor), it is installed while maintaining a stable installation independently without resorting to other configurations of the present invention.

The tight support rod 30 is configured to be fixed to the finishing panel 20 to be constrained to the wall reinforcement 40. In other words, the tight support rod 30 of the finishing panel 20 by restraining the finishing panel 20 fixed to the outer support frame 10 to the wall reinforcement 40 already stable (fixed to the base or floor) installed It is to maintain the installation state. The tight support rod 30 may be fixed by filling the groove 23 on the inner surface of the finishing panel 20 and inserting the groove 23 into the groove 23 to fix the filler 24 (adhesive, mortar, etc.). It can be restrained to the wall reinforcement 40 by tying the wires and the like.

It is preferable to have the lengthwise bar 30 as long as the thickness of the reinforced concrete wall to be constructed, so that the lengthwise bar 30 serves as a spacer between the finishing panel 20. At this time, the tight support rod 30 may be installed so as to contact the wall formwork with the length of the whole wall as shown in Figure 3 (a), but in some cases only the wall formwork as in Figure 3 (b) While being installed in contact with the other part may be installed to be restrained by fixing the hook 31 to the wall reinforcement (40).

The inner wall formwork 50 is constructed to be located inside the tight support rod 30, and is constructed to be connected to the long support rod 30 or to be self-supporting. If the inner wall formwork 50 is constructed to be tightly connected to the long support rod 30, the long support rod 30 should be provided in the form of a tie bolt, and if the inner wall formwork 50 is self-contained, the long support rod 30 is shown in Fig. 3 (a). And the inner wall formwork 50, as shown in Figure 3 (b) is sufficient. The self-supporting of the inner wall formwork 50 can also be provided by providing the brace 51 on the inner surface of the inner wall formwork 50.

Wall concrete 60 is a configuration that is poured between the finishing panel 20 and the inner wall formwork 50. The long support rod 30 and the wall reinforcement 40 are embedded in the wall concrete 60, whereby the finishing panel 20 constrained to the wall reinforcement 40 by the long support rod 30 is the wall concrete 60. It is integrated with

First, the outer support frame 10 is installed outside the finish line of the reinforced concrete wall to be constructed ((a) step). As described above, the outer support frame 10 may adopt a frame frame made of an assembly of a horizontal bar and a vertical bar, or a conventional outer wall formwork, and may further install a brace to reinforce the bearing force.

Subsequently, the upper and lower left and right sides of the finishing panel 20 on which the tight support rods 30 are fixed to the inner side are continuously joined together, and the outer support frame (using the fastener 100, the engaging piece, the fixing piece, and the connecting piece) has been examined. 10) fixedly installed on the inner surface (step (b)). At this time, the finishing panel 20 is mutually back to the filler material (22).

Next, the reinforcing wall (40) in which the horizontal reinforcing bars and the vertical reinforcing bars are assembled into the finishing panel 20 (step (c)). The wall reinforcement 40 is reinforced so that it may lead to the state fixed to the foundation or the floor. The reinforcing wall reinforcing bar 40 is constrained to the long support rod 30 fixed to the finishing panel 20 (step (d)). As a result, the outer support frame 10 and the finishing panel 20 may be stably erected while being restrained by being connected to the wall reinforcement 40.

Next, the inner wall formwork 50 is installed into the tight support rod 30 (step (e)). At this time, the inner wall formwork 50 is installed while being connected to the tight support rod (30) or to be installed to stand. In this case, the inner wall formwork 50 is free to mean that it is not installed in the tight support rod 30 is not connected, it can be installed while receiving the support provided separately.

Finally, after curing the wall concrete 60 between the finishing panel 20 and the inner wall formwork (step (f)), the outer support frame 10 and the inner wall formwork are removed (( g) step). The outer support frame 10 can be removed by dismantling the fixing piece 120 of the fixture. As a result, the finished integrally reinforced concrete wall as shown in FIG. 6 is completed.

On the other hand, it can be repeated according to the height of the reinforced concrete wall to be constructed, before the wall concrete (60) is placed to repeat the steps (a) to (e) as a construction cycle or (b) to (e) The steps may be repeated in one construction cycle, and in some cases, the state including the wall concrete 60 pouring step may be repeated in one construction cycle. In addition, if the step (g) includes the step of filling the soil to the inside of the wall concrete 60, it will be completed as a reinforced concrete retaining wall as shown in Figure 6 (b), and further, while fixing the grid in the multi-stage to the soil filling If done and anchored to the reinforced concrete wall, the reinforcement retaining wall will be completed.
