Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.
FIG. 1 is a perspective view showing a part of an embodiment of a monolithic prefabricated monolithic form according to the present invention.
A plurality of prefabricated steels (110) are disposed at positions spaced apart from each other by a predetermined distance from an outer side of a corner of a column (10) having a rectangular cross-sectional shape; A plurality of horizontal support members (120) horizontally spaced vertically apart from each other at an outer side of the main frame (110) on each side of the column (10); And a side wall of the column 10 is closed at an outer side of the horizontal support member 120 so as to serve as a mold for the column 10. The steel plate may be bent (140) arranged so that the direction of the trough (142) coincides with the longitudinal direction of the column (10); .
As shown in the embodiment of FIG. 1, in the present invention, the main-shaped steel material 110 has the outer side of each leg facing the outside of the column 10, and the edge of the main- And the horizontal support member 120 can be coupled to the outer side surfaces of the legs of the main type steel member 110.
The prefabricated steel reinforced concrete (PSRC) structure is formed by replacing all or part of the reinforcing concrete column members with the a-shaped steel.
The prefabricated column frame structure including the horizontal support members 120 connecting the plurality of main girder members 110 and the main girder member 110 can be manufactured in advance in the factory. It is possible to attach the deck deck form 140 and complete the post by placing the concrete in the field.
It is preferable that the golf deck formwork 140 is assembled at a factory for convenience of construction, but the present invention is not limited thereto.
1, the main girder 110 is disposed at each corner of a quadrangular cross-section 10, and a plurality of U-shaped steels 110 are disposed between the main girders 110 depending on the sizes of the columns 10 130 can be disposed.
The horizontal support member 120 connects a pair of main-shaped steel members 110 located on the same surface of the column 10 and is provided at a plurality of vertically spaced intervals along the longitudinal direction of the column 10 , And is coupled to the main-shaped steel member 110 by means of rivet, bolt, welding, or the like.
In this case, the horizontal support member 120 not only can attach the deck deck formwork 140, but also exerts an effect of confining the column by holding the main a-shaped steel material 110 from the outside, Can be replaced.
The horizontal support member 120 may be a Z-shaped steel. The horizontal support member 120 together with the valleys 142 of the deck formwork 140 constitutes the covering thickness of the column 10, so that the width is determined so as to form a sufficient covering thickness.
The deck deck form 140 is coupled to the outside of the horizontal support member 120 so as to close the side surface of the column 10 to serve as a mold for the column 10. The iron deck form is formed by the floor 141 and the valley 142, So that the direction of the troughs 142 coincides with the longitudinal direction of the column 10.
The golf deck formwork 140 will be described later with reference to FIG.
FIG. 2 is a perspective view showing a part of another embodiment of a monolithic prefabricated monolithic form according to the present invention, and FIG. 3 is a perspective view showing a coupling relationship between the horizontal support member 120 and the connecting member 150 in FIG.
As can be seen in the embodiment of FIGS. 2 to 3, the main section 110 of the main section 110 has the edge of the main section 110 of the main section 110, Shaped steel members 110 are connected to each other by a connecting member 150 in the horizontal direction and the connecting member 150 is connected to the outside of the legs of the main- And the horizontal support member 120 may be coupled to the upper end of the protruding end of the connecting member 150 .
Unlike the embodiment of FIG. 1 in which the corners of the main steel 110 are disposed on the corners of the column 10, in the embodiment of FIGS. 2 to 3, each leg end of the main steel 110 is supported by the columns 10 Shaped steel member 110 is disposed on the inner side of the column 10 so as to face the outer surface of the columnar steel member 110.
Therefore, when the transverse reinforcement is wound on the outer side of the main frame 110, the gap between the outer side of the legs of the main frame 110 and the transverse reinforcement occurs at the corner of the column 10, There is no worry. Further, since the joint plate is inserted into the column 10 when the column 10 is joined, it is advantageous in securing the coating thickness.
When the corner of the main steel 110 faces the outside of the column 10 during the splicing bolt operation of the upper and lower main steel 110, the hand is inserted into the column 10 to fasten the bolt In the embodiment of FIG. 2 in which the corner of the main steel 110 faces the inside of the column 10, the bolt fastening operation can be performed outside the column 10, so that the work is easy.
2 to 3, a connecting member 150 (not shown) for joining the side surfaces of the main-type steel member 110 and the horizontal supporting member 120 to the outer side surfaces of the legs of the main- ).
Therefore, since the horizontal support member 120 is coupled through the coupling member 150 without directly coupling to the U-shaped steel material 110, the time for transferring heat to the U-shaped steel material 110 can be delayed when a fire occurs , The fire resistance performance is improved.
In addition, since the main girder 110 is connected to the connecting member 150 passing through the inside of the column 10, it is possible to omit the additional hoop ropes, and it is also possible to use the auxiliary hoop ropes 180 if necessary.
The connection members 150 and the horizontal support members 120 are disposed in a plurality of directions such that the connection members 150 and the horizontal support members 120 are spaced apart from each other by a predetermined distance along the longitudinal direction of the columns 10.
2 to 3, the connecting members 150 are each formed of a steel, but a steel having various cross-sectional shapes such as a flat bar, a C-shaped steel, a C-shaped steel, and a Z-shaped steel can be widely used. In particular, the horizontal support member 120 uses a Z-bar, and the width of the horizontal support member 120 is determined in consideration of the covering thickness of the column 10.
The main structural member 110 and the connecting member 150 and the connecting member 150 and the horizontal supporting member 120 may be connected by rivet, bolt, welding or the like.
The horizontal support member 120 is engaged with the upper end surface of the protruded end of the connecting member 150, which is formed such that both ends of the horizontal support member 120 protrude from the leg ends of the main-
Figs. 4 (a) and 4 (b) are front views showing embodiments of a combined deck-formwork integrated prefabricated column according to the present invention, and Figs. 4 (a) and 4 Respectively.
As shown in FIG. 4 (a), the horizontal support members 120 provided on vertically adjoining surfaces may be positioned on the same plane.
However, if the end portions of the horizontal support members 120 provided on the vertically adjoining surfaces are in contact with each other, it may interfere with the flow of concrete when the concrete is poured.
4 (b), the horizontal support member 120 provided on each surface of the column 10 is spaced apart from the horizontal support member 120 provided on vertically adjoining surfaces by a predetermined distance in the vertical direction As shown in FIG. In other words, by arranging the heights of the adjacent horizontal support members 120 to be shifted from each other, a predetermined vertical space can be secured between the ends of the adjacent horizontal support members 120 to make the concrete flow more freely have.
5 is a perspective view showing an integrated prefabricated column according to the present invention.
5, the golf deck formwork 140 is coupled to the outside of the horizontal support member 120 so as to close the side surface of the column 10 to serve as a mold for the column 10, The steel plate is bent such that the floor 141 and the valleys 142 are formed alternately so that the direction of the valleys 142 is aligned with the longitudinal direction of the column 10. [
That is, the golf deck formwork 140 can be utilized as a lightweight permanent formwork to reduce the weight of the formwork, and is easy to handle, easy to install, and shorten the length of air compared to the conventional formwork. This can reduce the labor costs in the construction site and reduce the construction cost.
The deck deck formwork 140 should be able to withstand the weight and the concrete load of the concrete before curing. Since the golf deck formwork 140 in which the floor 141 and the valleys 142 are alternately formed is strong in rigidity, in the present invention, the direction of the valleys 142 is aligned with the longitudinal direction of the column 10, 140) was able to withstand the concrete side pressure. Therefore, it is possible to increase the height of the column 10 in which the concrete can be installed temporarily.
In addition, it is possible to sufficiently support the upper slab load by only the deck deck form 140 and the column framing before the post concrete is laid, so that the air can be shortened by installing the slab concrete before the post concrete.
The deck deck formwork 140 may be used as a permanent form after pouring concrete, or may be removed as needed.
When the surface of the deck deck formwork 140 is wet-finished with mortar or the like, the valleys 142 of the deck deck formwork 140 located on the surface of the post 10 increase the contact area with the finish material. As a result, the adhesion strength of the finish material is improved.
The golf deck formwork 140 is coupled to the horizontal support member 120 by any one of a direct-coupling screw, spot welding, pop rivet, or screw.
In particular, the Self Drilling Screw has a drill bit or a pointed end at the end of the screw, so it is possible to drill a hole in the mounting material and the base material directly without any additional processing, There are advantages. In addition, it is most preferable because it is strong enough to withstand pulling force and retaining force compared to ordinary nails and is safe without loosening even for long-term use, because it can withstand the concrete side pressure without being detached.
When dry finishing with a gypsum board or the like outside the column (10), it is possible to fix the finishing material such as the gypsum board to the column (10) by removing the direct-connection screw and tightening the screw in the screw hole left where the direct- have.

6 and 8 are views showing the embodiment of Figs. 1 and 2, respectively. Fig. 6 (a) and Fig. 8 (a) show the case where the size of the column 10 is small, 6 (b) and 8 (b) show a case in which only the main a-shaped steel material 110 is arranged, and the size of the pillar 10 is relatively large, Shaped steel material 130 is disposed.
In the present invention, each of the deck deck formwork 140 has a floor on the outermost side so that both ends of the horizontal supporting member 120 are vertically adjacent to each other, and the inside of the outermost floor 141 'of the deck deck formwork 140 And an engaging piece 143 bent outwardly at 90 degrees is provided at an end of the outermost floor 141 'of the deck decking die 140 so that the engaging piece 143 is vertically adjacent Is formed so as to overlap with the outer vertical portion 141 '' of the outer deck floor 141 'of the deck deck form 140 and the overlapping joining piece 143 and the outer vertical portion 141' And is connected to the horizontal support member 120 so that the deck deck formwork 140 is formed to be long in the horizontal support member 120.
As described above, the golf deck formwork 140 is composed of a floor 141 and a valley 142. In the present invention, one floor 141 is composed of one horizontal portion and a pair of vertical portions positioned at both ends of the horizontal portion, one of the valleys 142 is one horizontal portion, and the outer vertical portion 141 " Is defined as a vertical portion where the outermost floor 141 'of the deck deck form 140 faces outward.
7, the outermost floor 141 'is positioned at the end of the horizontal support member 120 positioned at the corner of the column 10, and the outermost floor 141' Of the outer side of the outermost floor 141 'of the other deck deck formwork 140 located on the outer side of the pillar 10 adjacent to the engaging piece 143 is provided with the vertically- The joining member 160 is fastened to the horizontal support member 120 such that the joining member 160 passes through the joining member 160 and the joining member 160.
This makes it possible to stably fix the edge of the deck deck formwork 140 by bringing the edge of the deck deck form 140 into close contact with the horizontal support member 120 and to provide an excellent end treatment of the deck deck formwork 140 .
6 and 7, when the horizontal support member 120 positioned on the adjacent surface of the column 10 is positioned on the same line, the deck deck formwork 140 on one side of the column 10, Only the outermost floor 141 'surrounds the end of the horizontal support member 120. Therefore, at each corner of the column 10, the golf deck form 140 and the horizontal support member 120 are coupled to only one side of the column 10 by the engaging member 160.
On the other hand, when the horizontal support members 120 positioned on the adjacent surfaces of the column 10 are not located on the same line, as shown in FIG. 8, The outermost floors 141 'of the deck form 140 each wrap the end of the horizontal support member 120. Therefore, at the corners of the column 10, the deck formwork 140 and the horizontal support members 120 are coupled to the one side and the other side of the column 10 by the engaging members 160, respectively.

In the present invention, the golf deck formwork 140 is characterized in that the number of the floors 141 is three as shown in FIG. 9A or the number of the floors 141 is four as shown in FIG. 9B .
Usually, the outer width of the column 10 is generally 600 mm or more in 100 mm increments. Therefore, if the unit width of the deck formwork 140 is two types, that is, a 300 mm type and a 400 mm type, a combination of two types of unit deck deck formwork 140 can be applied to all the columns 10 of various sizes. The deck form 140 can be applied.
9 (b), when a production facility is set with a 400 mm-type unit golf deck formwork 140 composed of four floors 141, only the width of the plate is controlled by the production facility, A 300 mm type unit golf deck form 140 having three pieces can be produced. Therefore, it is possible to maximize production and construction efficiency.
In the present invention, the height h of the floor 141 of the golf deck formwork 140 is the sum of the width w 3 of the engaging tab 143 and the thickness t of the golf deck formwork 140 .
This makes it possible to prevent the end of the coupling deck 143 from protruding out of the floor 141 when overlapping the end of the deck decking die 140 on the adjacent pillar 10 surface.
Generally, if the height h of the floor 141, that is, the depth of the trough 142, is large, the coating thickness is disadvantageous because the depth of the trough 142 is too small. So that deformation may occur. Therefore, it is necessary to appropriately calculate the depth of the troughs 142 in consideration of the coating thickness and the stiffness. The depth of the troughs 142 excluding the thickness t of the deck formwork 140 is about 15 mm Respectively.
In addition, the width of the width (w 2), the fitting piece (143) of the width (w 1), bone 142 of the floor 141 of the bone deck mold 140 according to the present invention (w 3) is a ratio of 7: 3: 1.5.
A plurality of unit deck forming dies 140 may be used in the lateral direction on each side of the column 10.

Since a single trough 142 can be formed by joining the joining pieces 143 of the adjacent unit unit deck formwork 140 when the plurality of unit trough deck formworks 140 are coupled together as described above, ) Is preferably one half of the width of the valley 142. [
Since the normal column 10 is designed in a unit of 100 mm, in order to be universally applied to the columns 10 of various sizes, it is necessary to use the adjacent troughs 142, the troughs 142 or the floor 141, 141 are preferably 100 mm in width.
Thus the goal if a dice deck 16.5㎜ the depth of the troughs (142), including the thickness (t) of 140, the coupling pieces 143, the width (w 3) is a suitable, and bone 142 of 15㎜ The width w 2 is 30 mm, which is twice the width of the coupling piece 143, so that the width w 1 of the floor 141 is optimal to be 70 mm.
However, it is also possible to manufacture a golf deck form with various sizes when machining a golf deck form with a press.
10 is a perspective view showing a monolithic prefabricated column integrated with a golf deck according to the present invention.
As can be seen from FIG. 10, the combined deck deck form integral pre-assembling column of the present invention may not join the deck deck form 140 to a part of the pre-assembled column framing.

The flange 121 prevents the concrete inside the column from flowing to the outside, that is, the cover, when the one flange 121 of the Z bar coupled to the main bar 110 faces downward, ) And the web 123 may not be filled with the concrete. Therefore, as shown in FIG. 14, the flange 121 located on the inner side of the column is coupled so as to face upward so that the concrete is tightly filled .
Therefore, it is possible to prevent the loss of the column section due to the failure of filling the concrete under the flange 121 of the horizontal support member 120, so that the front section can be regarded as an effective column section.
14, a heat insulating material 190 may be provided between the other side flange 122 of the Z-bar and the golf deck form 140 to block heat conduction.
At least one of the Z bars in the present invention is characterized in that a concrete flow hole 124 is formed in the web 123 at the longitudinal end portion.
In the case of the column corner covering portion, the concrete flow may be interfered with each other by the two horizontal supporting members 120, which meet with the main frame 110, respectively.
The concrete flow hole 124 formed in the web 123 of the Z bar prevents the end concrete from being poorly filled at corner portions of the column.
