SUPPORTING SYSTEM FOR A CONCRETE STRUCTURE HAVING AN EASILY MOUNTABLE SUPPORTING PANEL}

The present invention relates to a support system for concrete placing, and more particularly, to provide a support system for concrete placing, including an auxiliary panel that can be easily installed.

In general, the support system for placing concrete is called a formwork as a system that supports the kneaded concrete to maintain the desired shape while it is being cast and cured when the concrete structure is constructed. In the high-rise concrete structure, the retaining wall thickness varies depending on the load, so the upper and lower support portions (hereinafter, referred to as 'foam panels') of the structure are formed to have different thicknesses accordingly.

As described above, there is no problem in the case where the foam panel manufactured according to the thickness of the upper and lower retaining walls of the structure is correctly distinguished and installed for the lower portion of the upper structure, but the foam panels having different thicknesses are often used at the same time. In this case, since a predetermined gap is formed between the foam panels, an auxiliary means for filling in the gap is required.

In order to solve the above problems, a support system for concrete pouring with the auxiliary means has been developed.

Figure 5 is a perspective view before assembly of the support system for the conventional concrete pouring.

As shown in FIG. 5, the conventional support system for placing concrete is composed of a foam panel 100, a spacer 200, a coupling tie 300, and a fastening pin 400. As shown in FIG. 5, a plurality of grooves 240 are formed in the spacer 200 in a straight direction so as to correspond to the grooves 120 of the foam panel 100.

Therefore, the assembling worker has to check the grooves 240 of the spacers 200 and the grooves 120 of the foam panel 100 to coincide with each other and then insert the spacers 200 into the foam panel 100. There was this. In addition, if a mistake was found in the process of fastening with the fastening pin 400 after assembling by changing the direction of the spacer 200, there was a problem of releasing and reassembling the initial assembly.

FIG. 6 is a perspective view before assembly of another conventional concrete placing system for supplementing the disadvantages of the support system of FIG. 5; FIG.

Referring to FIG. 6, in order to overcome the problem of the support system according to FIG. 5, in Utility Model Registration No. 288410 filed and registered by the present applicant, instead of arranging the grooves of the spacers side by side, they are alternately arranged side by side. To solve this problem, one of the alternating spacer grooves must match the groove of the foam panel even when the spacer is incorrectly inserted by mistake.

However, even when the spacer grooves are alternately positioned, the fastening pins can only be fixed to the matching spacer holes, which may still cause inconvenience when the fastening pins must be inserted into the spacer holes at specific positions.

That is, in general, when pouring concrete using a foam panel, fixed pipes connected orthogonally to each other with a clamp 70 or the like support the foam panel to support the load of concrete introduced into the foam panel. Is connected to the foam panel by a hook (50).

If necessary, such a hook 50 needs to be located between the foam panel and the foam panel, that is, where the spacer is located. In this case, if the hook 50 is connected with the spacer using a fastening pin for fixing the spacer without using a separate fixing device, such a method is frequently used because the operation is more convenient and no separate member is required. do.

However, the position of connecting the fixed pipes to withstand the load of the concrete generally corresponds to the height of the top and bottom of each of the foam panels. As described above, when the spacer grooves are alternately positioned, the top or bottom spacer grooves are the foam panel grooves. Inconsistent with the present invention, there is still the inconvenience that the spacer 50 must be removed and reassembled in order to secure the hook 50 with this fastening pin.

In addition, the conventional spacer has a simple rectangular cross section whose width is the same as that of the foam panel. When placing such a conventional spacer between the foam panel, the operator has to be careful to align the foam panel with the outside, and if it is wrong, work efficiency is deteriorated. If the spacer and the form panel are misaligned with each other, There is also a problem that there is a risk of leakage of concrete if it is not located straight.

Therefore, the present invention has been proposed in view of the above problems, the object of the present invention can be inserted between the foam panels irrespective of the direction of the auxiliary panel in which the hook 50 is inserted for hanging on the fixed pipe It is to provide a support system for placing concrete so that it can always be fixed at the top or bottom regardless.

Another object of the present invention is for placing concrete with additional auxiliary fixing means (80) for solving the problem of coupling force that may occur when the hook 50 is positioned between the auxiliary panel and the foam panel as described above To provide a support system.

It is yet another object of the present invention to provide a support system for placing concrete, including a new auxiliary panel shaped to be more firmly fixed between foam panels.

1 is a perspective view before assembly of the support system for concrete placement according to an embodiment of the present invention.

As shown in Figure 1, the support system for concrete pouring according to an embodiment of the present invention is a foam panel 10, auxiliary panel 20, panel connection means 30, fixing means 40, hook ( 50).

The foam panel 10 is a main body portion which is installed to maintain the kneaded concrete in a desired shape, the flat plate 12, the support bar 14, the projection 16, the foam panel groove 18, the foam panel insert It consists of a hole 19. The flat plate 12 is formed of smooth steel as a part where concrete directly contacts. The support bar 14 is a support means installed on the flat plate 12 to withstand the load applied to the flat plate 12 by pouring concrete, and may be installed horizontally or vertically on the flat plate 12. The protrusion 16 is a portion protruding from the end of the flat plate 12, and a foam panel groove 18 and a foam panel insertion hole 19 are formed therein to connect a plurality of panels. The foam panel groove 18 is a portion into which the panel connection means 30 is inserted, and a foam panel insertion hole 19 to which the fixing means 40 is connected is formed therein.

The auxiliary panel 20 is a member formed in a shape corresponding to the protrusion 16 of the foam panel 10 so as to fill the gap between the foam panels 10 having different sizes, and the auxiliary panel groove 22 and the auxiliary panel groove 22. The auxiliary panel insertion hole 24 is formed. The auxiliary panel groove 22 is formed to correspond to the foam panel groove 18 at regular intervals, and the auxiliary panel insertion hole 24 is formed in the auxiliary panel groove 22 with the foam panel insertion hole 19. It is formed to correspond.

The auxiliary panel insertion holes 24 except for the top and bottom ends of the auxiliary panel insertion holes 24 are alternately formed to the left and right sides of the auxiliary panel groove 22 at positions corresponding to the foam panel insertion holes 19. . Due to the alternately positioned shape, since the fixing means is inserted only in the hole corresponding to the foam panel insertion hole after the auxiliary panel is inserted between the foam panels, the work can be performed without considering the insertion direction of the auxiliary panel.

Auxiliary panel insertion holes located at the top and bottom of the subpanel insertion hole 24 are not alternately positioned left and right, but the position corresponding to the right end of the right subpanel insertion hole is the right end, and the left subpanel insertion is performed. It has a shape in which the position corresponding to the left end of the hole is the left end.

Therefore, no matter which direction the auxiliary panel is inserted in, the top and bottom auxiliary panel insertion holes located at the top and bottom can penetrate the foam panel insertion hole, so that the top and bottom auxiliary panel insertion holes can always be hooked to the fixing pipe for supporting the panel. 50 can be fixed.

As the auxiliary panel 20, it is preferable to use a foamed mixed resin obtained by foaming a resin in which polyethylene (PE) and polypropylene (PP) are mixed. Since the weight of the auxiliary panel 20 made of the expandable resin is about one third of the weight of the auxiliary panel 20 made of the conventional resin, the weight of the auxiliary panel 20 is very light, and thus the handling is easy.

The panel connecting means 30 is a means for connecting the outer foam panel 10 corresponding to the inner foam panel 10, the coupling groove 32 is formed at both ends thereof.

The fixing means 40 is a means for coupling the auxiliary panel 20 inserted between the foam panels 10 and the fastening means 42 and the fastening pins 42 and the fixing pins 44. An example of the fastening means usable in the support system according to an embodiment of the present invention is shown in FIG. 4. However, the present invention is not limited to these examples.

Referring to FIG. 4, the fastening pins 42 are inserted from the foam panel inserting holes 19 through the corresponding auxiliary panel inserting holes 24 to the opposite foam panel inserting holes 19 to form the panels. Means for fastening. The fastening pin 42 has two fixing grooves 43 formed on both sides thereof, and the horizontal length of the fixing groove is preferably about 25 mm, and the interval between the fixing grooves 43 is about 20 mm. It is preferable. In addition, the fastening pins 42 are preferably rounded at both ends to facilitate insertion into the panel holes 19 and 24.

In addition, referring to Figure 4, the fixing pin 44 is inserted into the fixing groove 43 in close contact with the means for fastening the panel by the fastening pin 42, the fixing pin 44 has a cross section It is formed to be inclined from one end to the other end so that the length of. On the other hand, the portion abutting the foam panel 10 may be formed vertically and the opposite side may be formed to be inclined from one end to the other end.

The hook 50 has a hook shape for hanging the fixed pipe 60, and a hook hole 51 corresponding to a foam panel hole is positioned at one end of the hook-shaped opposite side, and is fastened through the hook hole 51. Fixing means 40 such as a pin penetrates and the hook hole 51 is fixed to the foam panel and the auxiliary panel. The fixed pipe 60 is connected to each other by the clamp 70 and the like to support the foam panels to withstand the load of the concrete introduced into the panels.

According to another embodiment, the support system for placing concrete according to the present invention includes auxiliary fixing means 80 for more rigid fixing of the auxiliary panel and the foam panel.

As described above, when the hook 50 is positioned between the auxiliary panel and the foam panel, the hook 50 is inserted between the auxiliary panel and the foam panel instead of being directly fixed by fixing means such as fastening pins. Since the hook 50 receives upward force through the fixing pipe 60 to move upstairs after the concrete is placed, there is a fear that the hook 50 is opened.

In addition, since the positions connecting the hooks 50 are adjacent to each other at the top and the bottom, the position where the foam panel and the auxiliary panel are directly fixed by the fixing means is farther away from each other, thereby requiring more firm fixing. For example, the fixing means is connected to the lower subpanel insertion hole of the uppermost subpanel insertion hole of the lower foam panel structure, and the fixing means is connected to the upper subpanel inserting hole of the lowermost subpanel insert hole of the upper foam panel structure. Since the position where the fixing means is connected is at least 60 cm (as is the case with three insertion holes in the middle), the demand for such fixing becomes more urgent.

In order to solve this problem, the present invention provides an auxiliary fixing hole (28) for penetrating the auxiliary fixing means (80) and the upper and lower auxiliary panel inserting hole of the upper and lower auxiliary panel inserting hole (80) directly above. Equipped.

The position of the auxiliary fixing hole 28 is preferably the center position of the uppermost subpanel insertion hole and the subpanel insertion hole immediately below it, and the center position of the lowermost subpanel inserting hole and the subpanel inserting hole directly above. Do.

In addition, the auxiliary fastening means 80 may be one of nails, wires, bolts, for example, and other general coupling and fastening means well known in the art.

2 is a front view and a side view of an auxiliary panel according to an embodiment of the present invention.

Figure 2 in the auxiliary panel according to the present invention alternately the auxiliary panel insertion hole 24 (hereinafter referred to as the top and bottom auxiliary panel insertion hole) positioned in the top and bottom of the auxiliary panel insertion hole (hereinafter referred to as the middle auxiliary panel insertion hole) The relationship with the shape of) is shown in detail.

The length of the lowermost subpanel insertion hole is extended so that the position of the left end of the lowermost subpanel insertion hole corresponds to the position of the left end of the left middle subpanel insertion hole, and the position of the right end of the uppermost subpanel insertion hole is the right middle auxiliary Corresponds to the position of the right end of the panel insertion hole. The height of the lowermost subpanel insertion hole is equal to the height of the middle subpanel insertion hole.

Since the lowermost subpanel insertion hole has an extended shape as described above, while the foam panel inserting hole has the same size as the subpanel inserting hole, the lowermost subpanel inserting hole corresponds to which direction the subpanel is inserted. And a fixing means such as, for example, a fastening pin passes through the foam panel insertion hole, the hook hole 51, the uppermost or the lowermost auxiliary panel insertion hole, in order to form the foam panel and the hook (50). ), The auxiliary panel is fixed together.

In addition, the size of the uppermost sub-panel insertion hole is extended and larger than the size of the fixing means such as the fastening pin, but the size and shape of the hook hole 51 and the size and shape of the foam panel insertion hole are the same as the thickness and shape of the fastening pin. There is no problem that the hook 50 is firmly fixed.

Figure 3a is a rear perspective view showing a new auxiliary panel according to another embodiment of the present invention.

In the auxiliary panel of FIG. 3A, a protrusion 26 in a vertical direction is formed on a rear surface (hereinafter, a rear surface) of a surface on which the auxiliary panel groove is located.

The protrusion 26 has a shape corresponding to the shape of the foam panel corresponding to the insertion of the auxiliary panel. That is, the foam panel generally used has a protrusion 16 at its vertical edge, so the protrusion 26 for inserting into the protrusion has a rectangular cross section. However, for ease of insertion during operation, it is preferable that the upper side has a trapezoidal shape that is shorter than the lower side in the insertion direction.

In addition, considering that the overall width of the foam panel generally used is 65mm and the width of the foam panel protrusion is 5mm, it is preferable that the length of the upper side of the appropriate trapezoid is about 47mm.

3B is a view showing a cross-sectional shape when the auxiliary panel according to the present invention having the protrusion 26 is inserted between the foam panels, and the height (a) and the position (b) of the protrusion 26 and the protrusion of the foam panel. The relationship with the specification is clear.

The height a of the protrusion 26 is related to the height a 'of the protrusion 16 of the foam panel. Since the height (a ') of the projections 16 of the foam panel is generally used is 4mm or less it is preferably the same or smaller. In addition, since the protrusions 26 of the auxiliary panels are embedded into the protrusions of the foam panels when they are connected to the foam panels, the protrusions 26 may be used to calculate the thickness of the auxiliary panels for considering the difference in thickness between the upper and lower retaining walls. 26) Only thickness is considered except height.

The position b of the protrusion 26 is related to the width b 'of the protrusion 16 of the foam panel. That is, since the width b 'of the protrusion 16 of the foam panel which is generally used is 5 mm, the protrusion 26 of the auxiliary panel also has a protrusion 26 from each other at a distance b or more from 5 mm from the outside thereof. It is preferably formed.

The length difference c between the bottom side and the top side, that is, the inclination degree of the hypotenuse of the trapezoid is sufficient to be easy enough to insert the auxiliary panel, preferably about 4mm.

As described above, according to the support system for concrete placing according to the present invention, even when a hook for connecting a fixed pipe is connected to a specific auxiliary panel insertion hole, the auxiliary panel can be inserted without considering the orientation. Work is easy and work time is shortened because no problem of reassembly occurs.

In addition, according to the support system for concrete placing according to the present invention, by providing an auxiliary panel having an auxiliary fixing means and an auxiliary fixing hole for penetrating the auxiliary fixing means, which may occur in a specific auxiliary panel insertion hole to which the hook is connected. The weakening of the bond between the foam panel and the auxiliary panel is solved.

In addition, according to the support system for placing concrete according to the present invention, by providing a subpanel formed with a protrusion corresponding to the protrusion of the foam panel, it is easier to work when inserting the subpanel between the foam panels and more firmly coupled between them do.
