The present invention relates to a truss frame system for plywood used when constructing a plywood wall to prevent soil during building or road civil works, and a truss frame support used for the frame system.

In more detail, even when the H-pile is not straight through the frame support, there is no influence on the balance of the plywood,

In the construction site according to the thickness of the plywood wall, the truss skeleton is introduced in order to omit the reinforcement process in which the workers bind to each other with a constant interval of the reinforcing bars to form a frame, and through the frame support. It relates to a truss frame system for plywood to facilitate the arrangement of the breakthrough.

In general, the plywood is installed to prevent ground collapse during road construction or ground construction of buildings. Conventionally, the H pile is mainly used for the construction of a plywood, and a plywood construction method using various H piles (for example, earth plate, CIP, SWC, sheet pile, and underground continuous wall) is known.

Utility Model Publication No. 1998-0017205 (July 06, 1998) `` Tiebolt Fixture for Formwork Panel Fixing '' and Utility Model Registration No. 0432710 (2004.02.10) `` Formwork Panel Fastening Member for Building a Building Wall, '' A member useful for maintaining the spacing of the formwork panel to be fastened is described.

As described in the above-mentioned Utility Models and Utility Model Publication No. 1995-0033458 (December 16, 1995) `` Formation Fixing Device for Underground Retaining Wall Construction, '' construction of plywood walls using conventional wood earthen boards is fixed to the ground at regular intervals. Fix the earth plate in the groove between the blades of the H pile, and fix the formwork panel spaced apart from the earth plate by using a tie rod, etc., with the reinforcing mold bar sandwiched between them, and inject the concrete mortar rule between the earth plate and the form panel. Is done through.

However, the construction method of the plywood has problems such as inconveniences of reinforcing the reinforcing bars in the formwork panel, reinforcement of air, increase of air, waste of labor, and economic problems.

In order to solve such an economical efficiency of the reinforcement, there is known a method using a truss muscle for the construction of buildings, bridges, plywood and the like.

Related to plywood among truss methods, there is a patent registration No. 0416835 (2004.01.16) which is combined with earth plate method.

As shown in Figs. 1A and 1B of Figs. 1A and 3B of the publication of the registered patent, the plywood of the registered patent is J-shape (3) and c-type on the thumb pile (1) In order to fix the vertical stopper 35 by fixing it with the type ring 31 of the collar 33 and to place the iron truss 2 on it, the iron truss 2 is upper and lower chords 21 and 22. The horizontal inner and outer muscles and the vertical outer periphery (25) and the vertical inner periphery (26) are arranged to face the formwork plate (6), the formwork plate (6) threaded hook bolt (5) or cut type The hook bolt 5a is fixed to the lower chord 22 and fixed by pouring concrete, and then the hook bolt 5a is separated to form a die.

Correspondence of each reference numeral and components in the drawings are as follows.

1: thumb pile 2: steel truss 21: high current 22: low current

23: lattice material 24: ring 25: vertical inner root 26: vertical outer root

3: J-shape 31: type ring 32; Hook 33: U-shaped shackle

5a: Single-head hook bolt 51: Square head 52: K-type washer

53: nut 6: formwork 7: bolt hole

However, although the registered patent uses a truss method, the J-type bolt 3 and the c-type bolt 33 are fixed to the front wing of one H-pile using bolts 34 and J-type bolts. Due to the work of fixing the vertical outer circumference (26) of the truss (2) to the ring of (3) one by one, the workability is inferior, and in order to firmly fix the J-shaped bolt (3) and the c-shaped bolt (33) the thumb pile ( Since it is necessary to weld in 1), the economic improvement effect of the reinforcement process using the truss method is inevitably faded.

In addition, the registered patent does not present a solution for the problem that the plywood wall is unbalanced because the H pile, that is, the thumb pile 1 is fixed out of the gravity direction.

The present invention has been proposed to solve the problem of resolving the inconsistency of the reinforcement process in the conventional plywood construction method using the H pile, and to lose the balance of the plywood to be built when the H pile is fixed out of the gravity direction.

Therefore, the present invention provides a truss frame support for drastically reducing the hassle and complexity of the reinforcement process still remaining when introducing the truss frame to the plywood construction, and to solve the problem caused by the H-file deviating from the direction of gravity. An object of the present invention is to provide a truss frame system using this support.

In addition, an object of the present invention is to introduce a variety of connecting means and fixtures to the frame system to ensure easy connection of the truss frame and the formwork panel.

In order to achieve the above object, the plywood frame support body according to the present invention is fixed to the H-pile exposed surface in a direction corresponding to the direction of gravity (縱 長 筋); And a plurality of protrusions up and down at a predetermined distance from the front of the H-file and the longitudinal muscle, and includes a transverse muscle (橫 短 筋) on which the skeleton is placed.

In addition, the truss frame system for plywood according to the present invention is a formwork panel in which a plurality of fitting holes spaced apart at regular intervals; A two-dimensional or three-dimensional frame structure consisting of two or more cast iron bars keeping a gap corresponding to the thickness of the construction wall and lattice bars for maintaining and reinforcing the gap of the cast iron bars; A plurality of H piles arranged laterally apart from each other at a rear of the construction wall; The longitudinal muscles fixed to the H-pile exposed surface in a direction corresponding to the direction of gravity, and the front and rear of the H-pile and the longitudinal muscles are plurally up and down at a predetermined distance from each other. Frame support including a transverse muscle (橫 短 筋) on which the frame is placed; And it comprises a connecting means positioned for each fitting hole of the panel to connect the frame and the formwork panel.

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

Reference numerals associated with the conventional framework system shown in FIGS. 1A and 1B and reference numerals of each component of the framework system according to the present invention shown in FIG. 2A below refer to mutually unrelated members.

In addition, in each of the drawings of FIG. 2A and the following, the tens and ones place, or the tens, ones place, and the same reference numeral refer to a member having the same function. You just need to understand the correlation between the sign and the component.

Meanwhile, in describing the frame support and the frame system according to the present invention, in FIG. 2A, the exposed side of the H-pile on which the support frame 30 is attached is referred to as the front side, and the opposite side is illustrated in FIG. 2A. It is determined to be rearward, up and down is determined based on the direction of gravity, and left and right are determined while looking at the front exposed surface of the H-pile (H).

First, as shown in FIGS. 2A and 3, the support 30 for the frame 10 is longitudinally fixed to the front exposed surface of the H pile H in a direction corresponding to the direction of gravity. ) 31, the H pile (H) and the longitudinal muscles 31 in front of each other at a predetermined distance from each other up and down, the transverse muscle (혀) is placed on each of the skeleton (10) Iii) 33.

The longitudinal root 31 and the transverse muscle 33 may be made of a deformed bar (shown in a flat form for the sake of simplicity in the drawing) that is commonly used in construction, and at the rear end of the transverse carrot 33 It is preferable that the bent part 33A for forming the welding joint area with the longitudinal root 31 is formed.

In addition, it is preferable that each of the front end of the transverse muscle 33 is further formed a skeleton departure prevention projection protruding upwards, as shown in the projection is a plate-like member 35 of the transverse muscle 33 It is made of a form that is welded to the front bent portion (33B). The protrusion 35 made of the plate member is formed with a recess 35a in which the front main reinforcing bar 11A of the frame 10 can be accommodated.

Next, as shown in Figures 2a and 2b, the truss frame system (F) according to the present invention is the H pile (H) fixed to the ground, the support 30 fixed to the exposed surface of the H pile (H) ), Connecting means 240 for connecting the frame body 10, the formwork panel 20, the frame body 10 and the panel 20 mounted on the transverse muscle 33 of the support 20, It includes.

In addition, the truss frame system (F) of the present invention may further include a space maintaining means for separating the front main reinforcing bar (11A) and the formwork panel 20 of the frame (10) by a predetermined distance.

When the frame 10 is produced as a ready-made product in a factory, it is composed of two main reinforcing bars 11A and 11B spaced apart from each other and a lattice reinforcing bar 13 for maintaining and reinforcing the spacing of the main reinforcing bars.

The lattice reinforcing bar 13 may be bent in a zigzag form and may be combined with the main reinforcing bars 11A and 11B at each bent portion thereof, but as shown in FIG. 6B, the two reinforcing bars 111A and 111B are perpendicular to each other. It may be transformed into a frame (110) having a lattice reinforcing bar 113 of the cross shape.

In addition, as shown in Figure 2b, each of the frame 10 arranged up and down on the support 30 may be bound to each other using a separate longitudinal reinforcement (15) if necessary.

In the present invention, as shown, the skeleton may be manufactured in a two-dimensional form in which two or more cast irons are arranged on a virtual same plane, or in a three-dimensional form in which three or more cast irons are arranged on different planes. The distance between the main bars is limited to correspond to the thickness of the wall to be constructed, that is, the spacing between the main bars should be arranged to be narrower than the thickness of the wall. This restriction is intended to prevent reinforcing bars, in particular cast iron, from the cast-in plywood outside the concrete.

Next, the formwork panel 20 has a plurality of fitting holes 21 spaced apart from each other at a predetermined interval, and may be made of wood such as a commonly used brand name veneer plywood, synthetic resin material such as FRP, or metal material, and repeated. For use, a known coating may be applied to the contact surface of the panel 20 with the concrete mortar, i.e., the rear surface.

The H pile (H) may be fixed to the ground according to various plywood methods, for example, by using a boring machine on the ground according to the cast in place pile (CIP) method, which is a kind of cast-in-place casting pile method By drilling a hole of a predetermined diameter, the H-file is inserted into the perforated hole, and then filled with gravel and the like in the remaining portion may be fixed by pouring.

In addition, after drilling with a boring device (for example, three-axis auger) to the planned depth in accordance with the SCW (soil cement wall) method, it may be fixed by injecting cement into the formed hole and then inserting the H pile into the stress material.

H file (H) shown in Figure 2b is fixed in accordance with the CIP or SCW method.

The advantage of introducing the framework 10 support 30 to the plywood wall construction according to the present invention is that when the H-file fixed on the ground is out of the gravity direction, the thickness of the plywood wall poured due to the skewed H-file is uneven This is because it prevents the balance from being lost or tilted.

More specifically, first, as shown in FIG. 4A, when the H file H is inclined to the left and the outside of the gravity direction G, the H file H to match the gravity direction of the support 30. The problem can be solved by welding to the exposed surface of.

In addition, as shown in FIG. 4B, when the H pile H is tilted back and forth, the left and right balances of the support 30 are welded to the exposed surface of the H pile, but the cross section 33 of the support 30 is welded. Different lengths can be used to balance the front and back of the skeleton on the transverse muscles. In the figure, since the upper end of the H pile is inclined forward, the transverse muscle located at the lower part is long and the transverse muscle located at the upper part is shorter.

If the upper end of the H pile is inclined rearward, the transverse muscle length may be adjusted in the opposite manner, and in the case of the H pile inclined back and forth and left and right, the combination of the methods of FIGS. 4A and 4B may be solved. .

2A and 2B, the support 30 is fixed to the front exposed surface of the H pile H as described above.

The length of the truss frame 10 placed on each of the transverse muscles 33 of the support 30 is varied as necessary, for example, about 5 to 10m may be used.

Connection means located for each fitting hole 21 of the panel 20 to connect the frame 10 and the formwork panel 20 can be implemented in various forms, in the present invention, the panel 20 and the frame It provides a variety of connecting means to make the connection of the sieve 10 more easily.

In addition, in the frame system F, the front main reinforcing bars 11A of the frame 10 and the panel 20 are spaced apart from each other by a gap maintaining means so that when the formwork panel is removed after concrete curing of the plywood, the front frame of the plywood is framed. It is preferable that the sieve is not exposed to prevent corrosion of the main reinforcing bar 11A constituting the frame 10.

As shown in FIG. 1A, the gap maintaining means may be a ring 24, that is, a protrusion in which the bent portion of the lattice muscles 23 continuously arranged in a zigzag form extends below the lower chord 22.

As will be described below, the present invention proposes a form in which the connection means and the space keeping means are particularly implemented in one member. In the description of such a composite member is referred to herein as a connecting means for convenience.

In the frame system F according to the present invention, the connecting means shown in FIGS. 5, 6A, and 7, respectively, are commonly used in the fitting hole for the connection with the frame body, in particular, the main reinforcing bar, the fitting hole of the panel 20 (21). ) Is a flat plate-type, in particular a dome-shaped disc-shaped support member (except for the support member of 5), which is inserted into the panel and is exposed to the lower part of the panel, the coupling portion and the connection portion connecting the exposed portion, and a kind of space keeping means. Cone shape) and connects the frame 10 and the panel 20 in the form as shown in FIGS. 2A and 2B.

First, the connecting means 40 shown in Figure 5 is any one of the frame 10, in particular the main reinforcing bars (11A) (11B) through the hook portion 41A of the coupling portion 41, the rear main reinforcing bar in Figure 2a 11B, the main reinforcing bars 11A and 11B and the hook portion 41A are preferably welded for more firm coupling.

In addition, the connecting means 40 shown is a member 43A of a concrete material having a support member 43 having a cone shape, and a washer of metal or synthetic resin material arranged on the upper surface of the member to prevent breakage of the concrete. 43a).

As described above, when the cone-shaped support member 43 is made of concrete, the reinforcing members (members forming the connecting portion and the exposed portion) of the connecting means are not exposed to the outside even when the formwork is removed after placing the plywood wall. It can increase the bonding force between concrete plywood.

When employing the connecting means 40 shown in Figure 5 in Figures 2a and 2b associated with the framework system (F), the cone-shaped support member 43 has a wide cross-sectional area of the upper frame 10 The front main reinforcing bar of 11A is in contact with, and a lower cross section is in contact with the rear panel 20 of the formwork.

That is, the support member 43 is interposed between the front main reinforcing bar (11A) and the formwork panel 20 of the frame (10).

In FIG. 5, the center of the cone-shaped member 43A is provided with a bushing B made of a nut member (in the present specification, a member of such a function is referred to as a 'nut bushing').

In particular, the bolt portion 44a of the connection portion 44 coupled to the nut bushing B shown and the bolt portion 45a of the exposed portion 45 are connected to each other, and the notch portion is connected to the intermediate position. N) is formed,

When removing the exposed part 45 from the nut bushing (B) when removing the formwork after curing of concrete, holding the cross-sectional extension 45A of the exposed part 45 with a tool such as a wrench and rotating the connection part 44 and the exposed part The notch part N of the intermediate part of the connection of each bolt part 44a and 45a of the part 45 is cut | disconnected as a starting point, and the said exposure part 45 is isolate | separated easily.

Of course, the role of the notch portion (N) can be achieved in the same manner when the connecting portion and the exposed portion are different from each other, but the complexity of the work in the case of assembling the connecting portion and the fitting portion separately to the support member 43 This can lead to problems such as higher prices.

The bushing B and the notch portion N may be introduced into the connecting means of FIGS. 6A and 7 without the cone-shaped member.

On the other hand, in Figure 5, the exposed portion 45 is located outside the panel 20 through the fitting hole 21 of the formwork panel 20, the cross-sectional area is increased at the end of the exposed portion 45 A cross-sectional area extension, in particular, an extension having a polygonal cross section and an expanded portion 45A having a hexagonal cross section is formed, and as shown in FIGS. 2A, 2B and 8A, the formwork panel 20 ) Is coupled to the slide plate (50A) to form a fixture for tightly fixing to the frame (10) to enable a close coupling of the support member 43 and the formwork panel 20 of the connecting means (40). .

The slide plate 50A is formed with a slit 53A consisting of an extended portion 53a near the lowest point and a narrow portion 53b communicating with the expanded portion 53a. In addition, both ends of the slide plate (50A) is formed with raised portions (51c, 51d) bent at a predetermined angle, the sliding plate 50A is exposed to the connecting means 40 by gently beating the raised portion with a tool such as a hammer. It is to provide a hitting part for making it easy to bite or loosen the portion 45.

In FIG. 2B, reference numeral 50a is an auxiliary means for allowing the slide plate 50A to be in close contact with the cross-sectional extension 45A of the connecting means 40, and has a length corresponding to the entire width of the formwork panel 20. And a hole 50h into which the exposed portion 45 is fitted.

In addition, the cross-sectional area expansion portion is exposed to the exposed portion 45 exposed to the outer surface of the cured concrete structure when dismantling the formwork panel 20 after curing the concrete in the framework system (F) to the notch portion (N) When cutting to remove the starting point, the cross-sectional area extension portion 45A having the hexagonal cross section is gripped with a tool such as a wrench and then rotated so that the exposed portion 45 can be more easily removed.

The cross-sectional area extension portion 45A may have an outer diameter greater than or smaller than an inner diameter of the fitting hole 21 of the panel, but as shown in FIG. 8A, the sliding plate 50A positioned at the front surface of the panel 20 and the slide plate 50A. When considering the coupling of the outer diameter of the cross-sectional area expansion portion than the inner diameter of the fitting hole 21, the inner diameter of the fixing plate 50B insertion hole 55, and the inner diameter of the slit 53A extension 53a of the sliding plate 50A It should be small and larger than the gap width of the narrow portion 53b of the slit 53A of the slide plate 50A.

Such cross-sectional extension of the exposed part is also common in the connecting means 140 and 240 for connecting the panel 20 and the frame 10 as shown in the connecting means of FIGS. 6A and 7.

In addition, it is essential for the function of the sliding plate (50A) in the skeleton system according to the present invention.

That is, in FIGS. 2A, 2B, and 8A, the fitting hole 21 of the panel 20 and the expansion part 53a of the sliding plate 50A slit 53A are introduced to the front of the panel 20. The exposed portion 45 is picked up by the narrow portion 53b of the slit 53A by the movement of the wedge-shaped slide plate 50A as shown in FIG. 8A, and the slide plate by the cross-sectional area extension portion 45A. 50A, eventually, the departure of the formwork panel 20 is restricted.

Next, the connecting means 140 of FIG. 6A is connected to the rear cast iron 111B of the frame 110 shown in FIG. 6B through the upper hook portion 141A of the coupling portion 141, and the coupling portion ( It is connected to the front main reinforcement 111A through the lower hook portion 141B of the 141, the main reinforcing bars (111A) 111B and the hook portion (141A) (141B) is preferably welded for a more firm coupling.

In addition, the coupling portion 141 and the connecting portion 144 constituting the connecting means 140, and the exposure portion 145 are all of the form of bending and deformation of one bar, such a connection means various modifications by those skilled in the art This is possible.

Subsequently, a support member 143 which is arranged under the hook portion 141B and contacts the rear surface of the formwork panel 20, and is a plate member coupled to the connection portion 144 extending below the hook portion 141B. A dome-shaped disc-shaped support member 143 and a stopper for limiting the upper movement of the support member 143 are provided.

The detent protrusion 144A shown is formed by deforming the connecting portion 144 by flat pressing, and cures concrete in the frame system F, and then protrudes on the outer surface of the cured concrete structure during disassembly of the formwork panel 20. When removing the exposed portion 145, the lower portion of the stop 144A may serve as a separation point for the exposed portion. That is, the stopper 144A itself may function as a notch part.

Furthermore, the disk member 143 having the dome shape may form a space portion R, into which the concrete mortar is not injected, as in the partially enlarged circle of FIG. 6C, thereby closing the fitting hole 21 of the form panel 20. It is possible to prevent the mortar is not ejected to the outside, this mortar loss prevention effect is superior to the case when the disc member 143 is arranged upside down unlike the illustrated.

In FIG. 6C, reference numeral 50B is a fixing plate 50B, which is a kind of sliding means to be described below with reference to FIG. 8B, and forms a fixture 50 together with the slide plate 50A, and the panel 20 to which the fixture is attached. Formwork assembly (M) is formed.

In addition, since the mortar is not introduced into the disk member 143 having the dome shape, the removal of the disk member 143 itself together with the removal of the exposed portion 145 of the connecting means 140 when removing the formwork after curing the concrete. Since it is possible to recycle the separated disk, it is excellent in terms of material cost saving.

In addition, the exposed portion 145 passes through the fitting hole 21 of the formwork panel 20 and is positioned in front of the panel 20. An extended portion 145A having a hexagonal cross section is formed at the end of the exposed portion 45. It is.

The connecting means 140 of FIG. 6A is an imaginary straight line connecting the connecting portion 144 and the exposed portion 145 and the frame located at the two hook portions 141A and 141B as compared to the connecting means 40 of FIG. 5. The imaginary straight lines connecting the centers of the two main reinforcing bars 111A and 111B of the sieve 110 are arranged to overlap each other. The center overlap between the connecting means and the main reinforcing bar is the same in the connecting means 240 shown in FIG. 7.

Next, the connecting means 240 shown in FIG. 7 is only a coupling part 241 connected to the front main reinforcing bar 11A of the frame 10 is a ring part 241B. ) The ring portion 241B of the connecting means 240 of the illustrated form is also formed by bending one bar forming the coupling portion 241, the connecting portion 244, and the exposed portion 245. However, the ring portion 241B of the connecting means 240 before the coupling of the lattice reinforcement 13 to the main reinforcing bars (11A) (11B) of the frame 10 due to the ring portion 241B There is a limitation that it is necessary to fit in the 11A, and after the skeleton is manufactured, it is almost impossible to couple the connecting means 240 to the skeleton. The connecting means employed in FIGS. 2A and 2B are shown in FIG. 7.

Next, FIG. 8B relates to a mold assembly M in which a fixture 50 including the sliding plate 50A shown in FIG. 8A is previously attached to the fitting hole 21 of the formwork panel 20 in a ready-made manner.

As described with reference to FIG. 8A, the sliding plate 50A of FIG. 8B is a slit consisting of an extension 53a near the lowest point and a narrow portion 53b communicating with the extension 53a and extending from the lowest point to the highest point. 53A is formed and has the protruding wedge part 53, and consists of the flat contact part 51 in which the said wedge part 53 is formed.

In particular, the means for attaching the slide plate (50A) to the panel 20 is a sliding means to enable the slide with the fixing of the slide plate, that is, the slide plate (50A) is the lower portion of the formwork panel (20) The sliding plate 50A is positioned on the formwork panel 20 in a state where the fitting hole 21 of the formwork panel and the slit 53A of the sliding plate 50A are coaxially arranged in a fixed state. Attach to the bottom to slide.

The fixed plate 50B of the sliding means in FIG. 8B includes a recess 51a and 51b formed at both sides of the sliding plate 50A and the contact portion 51 and a locking piece 59a capable of biting the recess from the outside. ) 59b is protruding.

In FIG. 8B, the fixing plate 50B is formed at a position corresponding to the fitting hole 21 of the panel 20 so that the cross-sectional area of the exposed portion 45 of the connecting means 40 as shown in FIGS. 2A and 8A.
