Thereafter, the concrete 300 is poured and cured so that the frame panel assembly 11 disposed in the horizontal and vertical directions is sealed.

The construction process for the wall system 111 manufactured by the above process can be divided into four cases as follows according to which process of the above manufacturing process is made in the factory.

First, referring to FIG. 5, the entire wall system 111 including the frame panel assembly 11 and concrete is prefabricated (precast) and the factory manufactured wall system 111 is transported to a construction site. Can be installed in place.

Second, referring to FIG. 6, the frame panel assembly 11 is prefabricated in advance, and the casting and curing of the concrete 300 is performed in the field after the frame panel assembly 11 is transported to the site.

Third, the entire process, such as the manufacturing process of the frame panel assembly 11, the concrete 300 pouring and curing process according to the assembly between the frame panels 10a, 10b may all be made immediately in the field. In this case, the production process is the construction process.

The wall system 111 of the present invention manufactured and constructed as described above has the following advantages.

2, in the wall system 111 of the present invention, the vertical frame panel 10b serves as a vertical reinforcing bar of a general concrete wall, and the horizontal frame panel 10a serves as a horizontal band reinforcing bar to act as a vertical load. In addition, it can resist the horizontal load and the shear force.

In addition, the wall system 111 of the present invention, unlike the conventional assembly or welding work using a separate wire (wire), the frame panel grooves each frame panel by adjusting the interval according to the required performance (100a) ) Can be easily assembled and installed in a way that can be fitted according to the modularity.

In addition, the panels assembled by the fitting method are embedded in the concrete wall after the concrete is placed to form a composite concrete wall with improved structural performance.

[ Example 2 ]

7 is a perspective view showing another structural example of the wall system of the present invention. The wall system 111a according to the present embodiment basically has the same configuration as that of the above-described [Example 1], but the frame panel assembly 11 ) Has a difference in that the formwork 400 using the high-strength iron plate is integrated to the composite concrete wall.

That is, the wall system 111a of the present embodiment shows a case in which the form 400 using high strength plate such as high strength steel sheet is integrated into the concrete wall into which the frame panel assembly 11 is inserted according to structural requirements. As such, in this case, not only the structural performance of the wall system is improved, but also a separate formwork dismantling operation may be omitted.

The wall system 111a of the present embodiment is basically the same as the [Example 1] except the formwork 400 using the high-strength iron plate, and is carried out by a manufacturing and construction process sufficiently understood from the [Example 1]. In order to avoid duplication of explanation, a detailed description of the configuration and operation will be omitted.

[ Example 3 ]

Figure 8 is a perspective view showing another structural example of the wall system of the present invention, Figure 9 is a perspective view of a longitudinal non-contact fixed high strength frame panel applied to the wall system of Figure 8, Figure 10 is a front view of FIG.

8 to 10, the wall system 111b of the present embodiment presents a composite wall system 111b having a structure suitable for application to a retaining wall structure or an inclined surface as well as a general wall applied to a building exterior wall. As one, basically the same configuration as the above-described [Example 1], there is a difference in that the structure of the frame panel constituting the longitudinal direction of the elements constituting the frame panel assembly 11 is configured to fit the slope.

That is, in the wall system 111b of the present embodiment, among the elements constituting the frame panel assembly 11, the width of the vertical frame panel 10b forming the panel in the height direction on the actual wall is from top to bottom along the height direction. It is characterized in that the width is formed wider.

In this case, while the width of the vertical frame panel 10b varies linearly, the lower width W2 may be wider than the upper width W1 (see FIG. 10), and the lower width W2 varies nonlinearly. ) May be wider than the upper width W1.

Meanwhile, in the present embodiment, as the width of the vertical frame panel 10b is formed in a different size along the height direction, each groove 100a formed in the panel body 100 has a length direction of the vertical frame panel 10b. The panel width direction depths (ie, depths of the grooves) of the grooves 100a may also be formed in different sizes along the coupling force with the concrete 300 that is placed in the body region where the grooves 100a are not formed. In order to increase the size of the through-holes (100b) can also be formed in different sizes along the longitudinal direction of the vertical frame panel in consideration of the width change.

The wall system 111b according to the present embodiment configured as described above has a vertical load and a retaining wall in which the vertical frame panel 10b is transmitted from the top according to a structural requirement of a wall system to be applicable not only to general walls but also to retaining walls or slopes. Alternatively, in consideration of the fact that the shear force acting by the earth pressure on the slope increases toward the lower side, the structural performance of the wall system is improved as the width of the vertical frame panel 10b is designed to become wider toward the lower side.

That is, when the wall system 111b according to the present embodiment is applied as a retaining wall structure or a slope reinforcing structure, the wall system 111 more effectively resists the shear force caused by the vertical load transmitted from the upper wall and the earth pressure acting behind the wall. .

On the other hand, the wall system 111b of the present embodiment is basically the same as [Example 1] except that the shape of the frame panel in the vertical direction is different, the production and construction process sufficiently understandable from [Example 1] In order to avoid duplication of explanation, the description of the detailed configuration and operation will be omitted.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them.

For example, in the drawings of [Example 1] and [Example 2] of the present invention, the groove 100a and the groove 100a of the horizontal and vertical frame panels 10a and 10b are assembled to meet each other, and the horizontal and vertical frame Although the upper part of the panel is exemplified in the same height so as to be located on the same plane without deviating from the upper part of the other panel, but the height of the horizontal and vertical frame panel in the mutually assembled state of the groove (100a) The depth in the panel width direction may be adjusted.

In addition, the formwork of the high strength iron plate in [Example 2] is also applicable to the wall system 111b shown in [Example 3] as needed.

Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.

The present invention is capable of reducing construction errors and high quality of construction quality when constructing wall systems through modularization of the members, and reducing construction costs through shortening of air due to minimizing construction facilities and field work, and improving the structural performance of wall systems. Can be improved.

Therefore, the present invention can be utilized for wall construction of high-rise construction, remodeling of high-rise construction, and the like, and can be effectively utilized for wall structures for retaining walls and slopes.
