The present invention relates to a supporter for supporting the slab construction formwork, and more specifically, a support that is placed on the floor, a pipe-shaped fixing bar coupled upright to the support so that the height can be adjusted, and the inside of the fixing bar at its upper end And a sliding bar having an upper end supported by a support member adhered to the bottom of the slab formwork, and on both opposite sidewalls of the fixing bar, from one side to the other end in the horizontal direction from the upper side to the lower side, and one side at the other end. By forming a linear zigzag through hole which is gradually inclined downward gradually toward the end, through the link movably coupled to the lower end of the sliding bar located inside the fixed bar, the opposite ends of the fixed bar Sliding rod penetrates the two through-holes, when dismantling slab formwork, formwork and support One such material and automatically sliding the through-hole in the lower moving slowly from the top of the fixed bar in accordance with by the weight, including the bar, to a formwork for slab construction supporter.

The multi-layered structure of concrete reinforcing structure begins with the installation of concrete wall and slab construction formwork. First, the interior space is made into a mold like a wall shape, and the ceiling slab construction board is placed on the ground. After the horizontal installation, the form of the concrete and the upper surface of the plate is formed by the method of curing and curing, the 'frame' and 'plates' called 'forms' are generally rectangular panels called formwork panels It is made by connecting a number.

Therefore, the construction of the wall and the slab starts by installing the formwork, which is a mold having an interior space and an upper surface to connect concrete with the plurality of formwork panels.

That is, one wall is made of concrete that is filled in the space between two wall formwork, each of which is installed so that the front faces face each other while being spaced by the thickness of the wall.

In addition, the ceiling slab formwork is coupled to the upper end of the wall formwork parallel to the floor so that the upper surface of the plurality of formwork panels form the same plane and the gap between the two opposing wall formwork is not blocked, between the two formwork and between Concrete is poured together on top of the slab formwork.

In the case of the formwork panel constituting the formwork as described above has been used mainly in the wood, but in the case of using the wood panel, as the assembly of the connection between the panel is made by nailing or tightening the wire, many formwork installation work Manpower and time are required, and also a lot of time and manpower is required to demolish the formwork after concrete curing.

Therefore, in recent years, wood-metal panels using metals such as iron or aluminum alloys (hereinafter referred to as 'aluminum') together with wood have been developed and used in various construction sites, and the range and scale of their use are rapidly increasing. There is a trend.

Referring to Figure 1 based on the conventional formwork structure that is a type of the concrete is poured by assembling the various panels as described above.

Conventional formwork is erected on the upper surface of the wooden foundation bar 12 fixed to the bottom surface (A) for the construction of each wall (W) and the bottom on the upper end of the two wall formwork 11 consisting of two upper and lower stages The slab formwork 13 is placed in parallel with the structure.

In addition, a plurality of parallel horizontal bars 14 (long lines) are in close contact with the bottom of the slab formwork 13, and a plurality of vertical bars 15 perpendicular to and parallel to these bottoms of the horizontal bars 14. After the yokes are in close contact with each other, the plurality of supporters S3 stand up to the bottom surface A along the bottoms of the vertical bars 15 to support the slab formwork 13, and the back of the wall formwork. Along the top portion, the horizontal bar 14 and the lumber T parallel to each other are coupled to the slab formwork 13 and the wall formwork 11.

At this time, the two wall formwork 11 facing each other in a state in which the flat front surface is spaced apart by the thickness of the wall (W) is coupled to a plurality of connecting pieces (C) to cross the wall in the thickness direction, and after completion of the wall construction each connecting piece Both ends of (C) are cut to dismantle the wall formwork, and the intermediate portion of each connecting piece C is buried in the wall concrete.

In addition, on each rear surface of the wall formwork 11, a plurality of formwork panels forming each wall formwork are prevented from being released from the initial assembly position by the pressure of the load of concrete poured for the construction of the wall W. Wall vertical support (S1) and wall horizontal support (S2) is combined.

In addition, the slab formwork 13, each front surface is in close contact with each opposite surface of the two sidewalls facing each other and spaced apart by the distance of the bottom (A) surface, each front surface of the two wall formwork, each back surface facing each other Since both ends are placed from the top of the side to the back side to form a top plate of the bridge spanning the two piers, the load of the entire concrete cast into the top of the slab formwork for the construction of the slab is combined with the upper ends at both ends of the slab formwork. It is a structure supported only by two wall formwork.

Therefore, in the structure as described above, because the slab formwork can not withstand the load of the concrete, as described above, a number of horizontal bars 14, vertical bars 15 and between the bottom and the bottom surface (A) of the slab formwork 13 and Supporters S3 are installed.

Therefore, the conventional formwork installed as described above, first, because the large number of the wall vertical support and the wall horizontal support must be coupled to the back of the wall formwork, the installation time is extended to extend the construction period, and secondly, to the wall formwork The time required to install and dismantle the support members and supporters because excessive support members such as horizontal bars, vertical bars, and lumber, and supporters for supporting them are necessary to support the intermediate portions other than both ends of the slab formwork supported by the slab formwork. This will be longer.

Third, various subsidiary materials for installing the formwork, namely slab formwork and various supporting members, are mainly used for plywood, lumber, or pipes, and each wood is combined with nails, and thus the various subsidiary materials for installing and dismantling the formwork. Due to the high breakage rate, the recyclability is low, so the initial form cost is inexpensive, but as a result, the construction cost is increased, and the cost for the disposal of waste materials is generated.

In order to solve the problems of the conventional formwork, a formwork structure consisting of a white body and a slab formwork is disclosed in Korean Laid-Open Patent Publication No. 2004-42029, in particular, the structure is a slab formwork (or "deck") It is made of "H" section and is supported by the flexible deck support bar, which makes it easy to dismantle slab formwork.

The deck support bar is smaller than the conventional formwork structure, but is supported by a conventional pipe support. When the deck support bar is bent downward after removing the support when dismantling slab formwork, the weight of the slab formwork is reduced. Due to the fast falling speed of the deck support bar may cause a safety accident.

That is, when a separate control means such as a spring is provided so that the bending progresses slowly in the bent portion of the deck support bar, there may be a big problem that a safety accident such as a head hitting the deck support bar that descends quickly may occur. In addition, sharp downward bending may cause deformation of the deck support bar.

However, since deck support bars are not only easily handled roughly at the construction site, but also have two bends per deck support bar, it is not easy to provide control means for slowing the bending speed in each deck support bar.

The present invention, in particular, to solve the problem of dismantling the slab formwork having a conventional formwork system wall and slab formwork together, the slab formwork support member in close contact with the bottom surface of the slab formwork, such as deck support bar It is installed between the floor and the floor to support the slab formwork including the support member, and when dismantling the slab formwork, it is not separated from the support member, but gradually raises itself in contact with the support member bent downward by the weight and the weight of the slab formwork. By lowering the present invention, the present invention provides a supporter that can prevent a safety accident that may be caused by a fast descending speed of the support member, as well as prevent the support member such as a deck support bar from being deformed or damaged due to a sudden lowering. There is a purpose.

The above object of the present invention is achieved by a linear zigzag through hole which is formed penetrating from top to bottom along opposing side walls of the pipe-shaped fixing bar.

Slab construction formwork supporter of the present invention, the support is placed on the bottom and provided with a height adjusting means upright in the upper end; A lower end of the pipe-shaped fixing bar which is erectly coupled to an upper end of the height adjusting means of the support and has an axial hollow; The bottom surface of the slab formwork supporting member is coupled to the reciprocating sliding in the up and down direction while the lower end is inserted into the inside of the fixing bar through the upper end of the fixing bar, and the upper surface is installed on the bottom of the slab formwork like the deck support. Sliding bar in close contact with; It consists of a link and a sliding rod connecting the lower end of the sliding bar and opposite side walls of the fixed bar.

The link is rotatably coupled to the upper end of the lower end of the sliding bar which is simply inserted into the fixed bar so that the lower end thereof can flow left and right, and the sliding rod is rotatable through the lower end of the link. Both ends deviating from both sides of the link penetrate the opposite side walls of the fixing bar.

In addition, on both opposing sidewalls of the fixed bar through which both ends of the sliding rod pass, linear zigzag through-holes are formed to extend from the upper portion to the lower portion in the same position and shape. The technical and structural features of the present invention are coupled to both sidewalls of the fixing bar in such a way that they penetrate the two through holes formed on each of the sidewalls of the opposite fixing bar.

At this time, the linear zigzag through-holes respectively formed to be opposed to each other at the same position opposite the side walls of the fixing bar is inclined downward from the upper side of the fixing bar toward the lower end from one side portion of the side wall in the horizontal direction to the other end portion thereof. It is formed to extend from the top to the bottom of each side wall in a sequential and repetitive form inclined downward from the other end to the one end again, the horizontal portion is provided at the upper end of the through hole.

Therefore, when both ends of the sliding rods respectively inserted in the two through holes facing each other are positioned at the horizontal portion of the upper end of the through holes, the sliding rods can be moved in the left and right directions with respect to the fixing bar, When it is impossible to move in the direction, and is positioned on the inclined portion beyond the horizontal portion of the through hole, it moves downwardly from the top to the bottom of the fixing bar alternately in the left and right directions along the zigzag-shaped inclined through hole. Looking at the use of the present invention support bar is as follows.

First, the sliding bar is pulled upward by the required length from the fixed bar, and then one end of the sliding rod is inserted into the inside of the fixed bar through one horizontal through hole horizontal part of the fixed bar from the outside of the fixed bar. One side end passes through the lower end of the link coupled to the lower end of the sliding bar inside the fixed bar, and then penetrates the horizontal part of the other through hole, and the other end of the sliding rod located outside the fixed bar is formed of the one through hole. The supporter of the present invention is set so as to pass through the horizontal portion.

That is, in a state where the sliding rod penetrates the link, the sliding rod is fixed by allowing both ends of the sliding rod off both sides of the link to penetrate each horizontal portion of the two through-holes of both side walls facing each other from the inside of the fixing bar. It can be moved only in the left and right directions within the through hole of the bar.

Then, the support bar coupled to the sliding bar and the sliding rod as described above, upright between the support member, such as a deck support installed on the bottom of the slab formwork and the bottom, and then using the height adjusting means coupled to the upper end of the support bar By raising the height of the upper surface of the sliding bar coupled to the fixed bar in close contact with the bottom of the support member, the installation of the supporter of the present invention is completed.

When the curing of the concrete is made in the state in which the installation of the support is completed as described above, the slab formwork and the support member in close contact with the bottom thereof are in close contact with the bottom (ceiling surface) of the slab by the supporter in a state of being separated from the slab. Becomes

Therefore, when the sliding rod is moved from the horizontal portion of the through hole to the inclined portion by applying a force in both directions to the horizontal ends formed on the horizontal portion formed in the upper end of the fixing bar through hole of the supporter, By the weight of the slab formwork, the supporting member, and the sliding bar that are in close contact, the sliding rod coupled to the lower end of the sliding bar via the link slides along the inclined portion of the through hole and slides simultaneously from the upper side to the lower side of the fixing bar. It moves slowly in a zigzag shape.

Then, the sliding rod is stopped to reach the lower end of the through hole, it is possible to easily dismantle the support member and the slab formwork placed on the upper surface of the supporter sliding bar sufficiently lowered.

As described above, the descending speed of the sliding bar which is lowered together in the fixed bar together with the downward movement of the sliding rod by the weight of the slab formwork, etc., depends on the inclination of the through hole that serves as a track in which the sliding rod moves. If the slope is changed to be larger than necessary, the descending speed of the sliding bar is faster than necessary, and a safety accident may occur.

That is, the inclination of the through hole is most preferably between 3 and 30 degrees, and when the inclination is less than 3 degrees, the sliding rod is not easily moved downward, and when the speed exceeds 30 degrees, the speed is more than necessary. Can be faster.

In addition, the descending speed of the sliding bar may be changed by various factors such as the friction state between the outer circumferential surface of the sliding rod and the inner surface of the through hole in addition to the inclination of the through hole, the weight of the slab formwork, the supporting member, and the sliding bar. The inclination of the through hole may be out of the inclination range as necessary.

In addition, the sliding rod rotatably coupled to the link has a shape such as a circular rod or a circular pipe having a circular cross section so that the outer circumferential surface thereof is suitable for rotation. The slide is rotated along the inclined through hole, and the coupling portion of the link to which the sliding rod is coupled also has a cylindrical or ring-shaped structure to rotate in a state where the sliding rod is penetrated.

At this time, the wear of the sliding rod is prevented or reduced, and in order to smoothly rotate the sliding rod, the through-hole of the circular cross section is coupled to the inner hole of the link coupling portion, and then the sliding rod is attached to the through-hole of the bushing or the bearing. It is also preferable to penetrate through.

However, when the bearing is combined, the rotation of the sliding rod may be extremely fast, and in view of this, the inclination of the through hole should be sufficiently lowered.

Details of the effects and the resulting effects, including the object and technical configuration of the present invention will be clearly understood by the following description with reference to the drawings showing a preferred embodiment of the present invention.

2 is a perspective view of the first embodiment support of the present invention, FIG. 3 is an exploded perspective view of the first embodiment support of the present invention, and FIG. 4 is a state diagram of the use of the first embodiment support of the present invention.

Prior to the description of the present invention, the shape of the fixed bar constituting the supporter of the present invention will be described. Since the sliding bar is inserted into the fixed bar and reciprocates in the up and down directions along the axial direction, the hollow is provided. The shape of the pipe is preferred, and the shape of the pipe is not limited to the shape of a circle, a square, a polygon, etc., the square pipe shape is most preferable in consideration of the rigidity and manufacturing conditions of the fixed bar.

That is, it is possible to sufficiently solve the rectangular fly shape as the shape of the fixed bar, but in the case of the circular pipe shape, the rigid zigzag through-holes are formed in the opposite side walls, and the rigidity is insufficient. This is because production is tricky.

Therefore, hereinafter, it will be described with reference to the fixed bar of the rectangular pipe shape shown in the drawing.

As shown, the slab construction formwork supporter of the present invention, the support 21 is placed on the bottom and the height adjusting means 21A is coupled to the upper end;

A linear zigzag through hole having a lower end coupled to the upper end of the height adjusting means 21A provided in the support 21 and penetrating the respective side walls W1 at the same position of the opposite side walls W1 ( H) is a pipe-shaped fixing bar 22 extending from the top to the bottom, respectively;

It is possible to reciprocate in the up and down direction in the lower end is inserted into it through the upper end of the fixing bar 22, the upper surface is in close contact with the bottom of the support member (B) installed on the bottom of the slab formwork (13) A sliding bar 23;

Both sides of the lower end of the sliding bar 23, the upper end both sides are rotatably coupled to each other, the lower end can flow in both the left and right directions, the link 24 provided with a cylindrical coupling member (F) on both sides of the lower end Wow;

Rotatable in a state penetrating the inner diameter of the coupling member (F) provided at the lower end of the link 24, both ends penetrate the two through holes (H) facing the fixing bar 22 It is comprised by the sliding rod 25 which is movable along the through-hole H, and has an outer peripheral surface of an arc shape.

In the supporter of the present invention configured as described above, the height adjusting means 21A having the lower end coupled to the upper end of the support 21 may have various forms such as hydraulic, electric, screw, etc. The upper end is screwed to the lower end of the fixing bar 22 in the state that the lower end is rotatably coupled to the upper end of the support or screwed, the bolt member having a handle (h) on the outer peripheral surface is an example For example, by rotating the bolt member using a handle (h) fixedly fixed to the outer peripheral surface of the bolt member, the distance between the support bar and the fixing bar respectively screwed to the upper and lower ends of the bolt member, such as a turnbuckle is adjusted or The height of the fixing bar 22 is adjusted in such a manner that only the fixing bar 22 screwed to the upper end of the bolt member is adjusted.

However, in view of the rigidity and the height adjustment time of the supporter of the present invention, it may not be desirable to adjust the adjustment length of the entire height required for the support only by the rotation of the height adjusting means 21A.

Therefore, after performing most of the entire length that needs to be adjusted, only the remaining small portion, that is, the final height adjustment with a small adjustment range, is performed by the height adjusting means 21A to increase the adhesion between the supporter and the slab formwork supporting member. In this case, as shown in Figure 5, the sliding bar 23, the main sliding bar 23A having a pipe shape such as a fixed bar to be inserted into the fixed bar 22, and It is preferable that the auxiliary sliding bar 23B be movable in the up-down direction in a state in which the lower end is inserted into the inner through the upper end of the main sliding bar 23A.

In this case, first coupling holes H 'are provided at the same heights on both sidewalls of the main sliding bar 23A, and first couplings of the main sliding bar 23A are formed on both sidewalls of the auxiliary sliding bar 23B. To form a plurality of second coupling holes (H ") arranged at regular intervals in the up and down directions so as to coincide with the balls (H '), respectively, the main sliding bar (23A) and the auxiliary sliding bar (23B), After the withdrawal height of the auxiliary sliding bar 23B is adjusted, the sliding bar 23 is formed by the fixing rod 23C which simultaneously passes through the first coupling hole H 'and the second coupling hole H "corresponding thereto. ) Length is adjusted.

That is, as described above, after adjusting the lengths of the main sliding bar 23A and the auxiliary sliding bar 23B, the height of the final supporter may be adjusted through the height adjusting means 21A.

The up and down position fixing of the sliding bar 23 in the state in which the supporter of the present invention as described above is installed on the sliding rod 25 located in the horizontal portion H _H of the through-hole H of the fixing bar 22. When the slab formwork is dismantled, the sliding rod 25 is positioned at the horizontal portion H _H of the through hole H so that the sliding rod 25 descends along the through hole H to the lower portion of the fixing bar 22. Sliding rod 25 has to be moved to the inclined portion (H _I ) of the through hole (H).

However, in order to move the sliding rod 25 to the inclined portion (H _I ) of the through hole (H) through the two through holes (H), both ends of the sliding rod 25 protruding to the outside through the through hole on one side of the inclined portion (H _I) of the through hole of the inclined section bars, the sliding rod 25 both ends of failure to price the two places at the same time, the sliding rod 25 of the required value at the same time the side (H _I) of (H) , The other side may be located in the horizontal portion (H _H ), in this case, the load applied to the supporter is concentrated to one side, the supporter may be deformed or collapsed.

Accordingly, as shown in FIGS. 6 to 8, upper sides of the opposite sidewalls W1 of the fixing bar 22 corresponding to the upper end of the through hole H, so that both ends of the sliding rod 25 can move at the same time. A horizontal stepped portion J is formed on the outer surface, respectively, and the bottom portion is in contact with the top surface of the stepped portion J so that the center portion can be reciprocally moved left and right along the top surface of the stepped portion J. It is also preferable to couple the plate-shaped stopper 26 penetrated by the upper portion of the 22 to the outer surface of the fixing bar 22, which will be described below.

The stopper 26 has a plate shape and has a fixed bar through-hole H1 penetrated by the fixing bar 22 therein, and the two inner circumferential surfaces of the fixed bar through-hole H1 facing each other in the width direction. The silver is not in close contact with the outer surfaces of the opposite sidewalls W1 of the fixing bar 22 so that the movement of the stopper 26 is not disturbed, and the bottom of the stopper 26 is in contact with the bottom of the step J. The length of the fixing bar through-hole H1 is longer than the length of the support bar 22 in the left and right directions, and the stopper 26 is a stepped portion of the fixing bar 22 by the impact applied from the outside. J) It is a structure which can reciprocate in the left-right direction about the fixed bar 22 along the upper surface.

In addition, the two inner peripheral surfaces of the width direction opposite to the fixing bar through-hole H1 are provided with a falling groove G crossing the inner peripheral surface in the up and down directions, respectively, and opposite end portions of each of the falling grooves G facing each other. Between the upper end of each and the upper surface (S _U ) of the stopper 26 is inclined surface (S _I ) which is inclined downward toward the falling groove (G) side, respectively.

At this time, there is no horizontal portion at the upper end of the fixing bar 22 through-hole (H), the lower groove (G) of the stopper 26 when the stopper 26 is completely moved to either the left or right side of the fixing bar 22. ) Are shifted from each other in the vertical direction with the upper end of the fixing bar 22 through-hole (H).

That is, when the supporter of the present invention is installed, both ends of the sliding rod 25 penetrated and coupled to the link 24 pass through the upper ends of both sidewalls W1 of the fixing holes 22, respectively. After that, the state is placed on the upper surface (S _U ) adjacent to the inclined surface (S _I ) of the stopper (26), and when dismantling the slab formwork (13), a striker is applied to one side of the stopper (26) to the stopper (22) against the fixing bar (22). When only 26 is slightly moved to one side, the lower groove G of the stopper 26 and the upper end of the through hole H coincide in the vertical direction, and at the same time, the sliding rod that is located on the upper surface S _{U of the} stopper ( the both end portions 25) is in a state to move to the inclined surface (S _I) of the stopper (26).

Accordingly, both ends of the sliding rod 25 slide along the inclined surface S _I of the stopper 26 to move to the upper end of the lowering groove G of the stopper, and move to the upper end of the lowering groove G. The sliding rod 25 descends along the descending groove G, leaves the lower end thereof, and then reaches the upper end of the through-hole H of the fixing bar 22, and then continuously descends along the inclined portion H _I.

At this time, the inclined surface (S _I ), when the deviation occurs in the movement of both ends of the sliding rod 25 by the stopper 26, the sliding rod 25 by slowing the initial moving speed of the sliding rod 25 It is formed so that an operator can correct the deviation of movement of both ends, and it does not need to be provided.

However, when not provided with the inclined surface (S _I ), it is preferable to make the shape of the lower groove (G) in a funnel shape, that is, the width becomes narrower from the upper end of the lower groove (G) toward the lower end, By doing so, it is possible to prevent or minimize the deviation of the movement of both ends of the sliding rod 25 which may be generated.

Then, the plate-shaped stopper 26 is fluidly coupled to the outer surface of the side wall W1 of the fixing bar 22 corresponding to the upper end of the through hole H, so that the two ends of the sliding rod 25 are not positioned at both ends. , The slab formwork 13 can be dismantled by hitting only one side end of the stopper 26.

In order to smoothly operate the supporter of the present invention whose height is reduced by the weight and externally applied loads as described above, the left and right reciprocating movements of the link 24 should be possible, and the link ( The structure of 24 may take various forms, but in FIG. 3 and FIG. 5, the straight rod-shaped link, which is the simplest form, is illustrated as an example, and the upper end of the link is rotatably coupled to the lower end of the sliding bar 23. As long as the lower end of the link can freely flow in the left and right directions within the fixing bar 22 around the upper end, as shown in FIG. 9, a plate-shaped shape is possible, and the structure thereof is a specific shape. It is not constrained.

As described above, the supporter of the present invention is gradually lowered by the weight of the slab formwork and the supporting member which is supported in close contact with the upper surface thereof, so that the slab formwork is easily dismantled and the risk of occurrence of a safety accident is almost eliminated. In addition, when used in conjunction with the curved deck support can be easily systemized to dismantle the wall and slab formwork is expected to reduce the labor load as well as construction costs.
