Description

Gangform lifting system {Gangform Climbing system}

The present invention relates to a gangform lifting system, and more specifically, to a gangform lifting system that can easily install a guide shoe and reliably prevent the rail from falling after installation.

Gangform is mainly used as a large form that is used to manufacture and use a cage for the scaffolding of external wall form installation/disassembly work and plastering/decoration work in structures with the same cross-section on the top and bottom, such as in high-rise apartments. .

These gangforms use the gangform climbing system.

The gangform lifting system is manufactured by combining the work platform and scaffolding for formwork installation with rails. The gangform lifting system engages with a guide shoe installed on one side of the structure and rises hydraulically without a crane.

Specifically, when a part of the reinforced concrete structure is constructed, a guide shoe is installed on one side of the structure, and a gangform lifting system equipped with a work platform, scaffolding, etc. is fixed to the guide shoe. Concrete is poured while installing formwork for concrete pouring using a gang form lifting system fixed to a guide shoe, and through this, part of the structure is constructed.

After constructing part of the structure, the rail is raised to the upper part through a hydraulic cylinder provided in the guide shoe, and the above-described method is repeated to construct the upper part of the structure.

This lower rail 110 is a pair of "ㄷ" shaped steels joined with open surfaces facing each other and configured to be arranged at a predetermined distance. A pair of “ㄷ” shaped steels are coupled to each other by the fixture 111 to maintain a spaced apart state.

The fixture 111 of the lower rail 110 is configured to engage the upper end of the hydraulic cylinder 200 provided on the guide shoe 130, and when the hydraulic cylinder 200 is extended, the lower rail 110 It rises, and when the inflow cylinder is reduced, the lower rail 110 descends. In this way, when the lower rail 110 is raised or lowered, the gang form, including the upper rail 120 connected to the lower rail 110, is also configured to rise or lower.

The upper rail 120 extends vertically, is disposed above the lower rail 110, and is coupled to the gang form.

Specifically, the upper rail 120 is arranged on the upper side of the lower rail 110 and is configured to be coupled to the gang form that serves as the external formwork of the structure. After constructing part of the structure, the upper rail 120 is slid and moved away from the lower rail 110 to separate the gang form from the outer wall of the building, and then the lower rail 110 is raised to allow the gang form to construct the remainder of the structure. make it possible

The lower part of the upper rail 120 is arranged to partially overlap the lower rail 110, and the lower part of the upper rail 120 is located in front of the upper part of the lower rail 110.

This upper rail 120 has the same shape as the lower rail 110 and is made of a pair of “ㄷ” shaped steel, with the open surfaces joined to face each other and arranged at a predetermined distance. A pair of “ㄷ” shaped steel beams are coupled to each other by a fixture 121 to maintain a spaced apart state.

The guide shoe 130 is fixedly installed on the outer wall of the building and guides the vertical movement of the lower rail 110. Specifically, a plurality of guide shoes 130 are installed in the vertical direction, and the lower rail 110 is slidably coupled to each guide shoe 130.

After construction of a part of the structure is completed, the guide shoe 130 located at the bottom is removed from the outer wall and then placed again at the top of the structure so that the remaining part of the structure can be constructed.

This guide shoe 130 includes a shoe body 131 fixed to the outer wall, and a hook portion 132 rotatably coupled to the shoe body 131 and engageable with the lower rail 110.

The shoe body 131 is configured such that a pair of plates facing each other are connected to each other at the rear, and the connected rear is fixed to the outer wall of the building.

Guide portions 131a are provided on both sides of the shoe body 131 to form vertical passages into which the lower rail 110 can be slidably inserted. The guide portion 131a is configured to have “>” and “<” shapes facing each other so that the lower rail 110 is sandwiched between them.

The hook portion 132 is rotatably coupled to the inside of the shoe body 131 and has a horizontal position parallel to the horizontal direction to support the fixture 111 of the lower rail 110, and the lower rail 110 is When rising, the fixture 111 of the lower rail rotates between vertical positions so as not to interfere with the rising.

The free end of the hook portion 132 has a hook shape to support the fixture 111.

A hydraulic cylinder may be coupled to the upper part of the shoe body, and the lower rail 110 can be raised or lowered by extending the hydraulic cylinder 200 coupled to the upper part of the shoe body.

The rail bracket 140 extends in a horizontal direction perpendicular to the longitudinal direction of the lower rail 110. This rail bracket 140 is fixedly installed on the side of the lower rail 110 and includes a pair of bracket supports 141 extending forward, and a pair of bracket supports 141 that are fixed to the bracket support 141 and extend the length of the lower rail 110. It is configured to include a horizontal rail portion 142 extending in a direction perpendicular to the direction.

The bracket support portion 141 protrudes forward from both sides of the lower rail 110 and is made of a thin plate. One side of this bracket support portion 141 is bolted to the side of the lower rail 110, and the other side is bolted to the side of the horizontal rail 144.

The horizontal rail portion 142 consists of a pair of “ㄷ” shaped rigid bodies with the open portion facing inward. Each of them includes a rectangular bottom plate 1421 extending long in one direction, a rail side plate 1422 facing each other and standing upward from a long side edge of the bottom plate 1421, and the rail side plate 1422 ) consists of a horizontal rail (1423) bent toward the inside. An open opening is formed between the pair of bottom plates 1421, and an open opening is also formed between the pair of horizontal rails 1423. A slider 151 is movably coupled to the opening between the horizontal rails 1423.

The roller bracket 150 is installed to be slideable on the rail bracket 140 and is coupled to the upper rail 120. This roller bracket 150 consists of a slider 151, a connecting member 152, and an upper support body 153.

The slider 151 is movably coupled to the rail bracket 140, and has a pair of slide plates 1511 on the front and rear sides that can be fitted and coupled to the horizontal rail 144, and the slide plate 1511 ) consists of an intermediate connection part 1512 that connects them to each other. The slide plate portion 1511 has an upper part in an inverted trapezoidal shape, a lower part in a trapezoidal shape, and the center between the upper and lower parts in a narrow square shape to connect the upper and lower parts. The center between the upper and lower parts is concave inward so that the horizontal rail 144 is fitted into the concave portion.

A roller 1512a is installed in the middle connection 1512 to support the upper or lower surface of the horizontal rail 144 so as to stably support the horizontal rail 144, and the roller 1512a is installed on the horizontal rail 144. ) are arranged alternately so as to contact the upper and lower surfaces.

The connecting member 152 extends upward from the center of the slide and is arranged to stand vertically. The lower part of the connecting member 152 is fixed to the slider 151 and the upper part is fixed to the upper support 153, so that the slider 151 and the upper support 153 are connected to each other.

The upper support 153 extends upward from the connecting member 152 and is coupled to the upper rail 120. The lower part of the upper support 153 is fixedly coupled to the connecting member 152, and the upper part is configured to extend upward. The upper support 153 is configured to be coupled to the lower part of the upper rail 120.

The upper support 153 and the upper rail 120 are coupled to move in conjunction with each other in the horizontal direction, but are configured to move independently of each other in the vertical direction. Specifically, when the upper support 153 moves forward, the upper rail 120 also moves forward along with the roller bracket 150 and its independent movement is restricted, but when the upper rail 120 moves up and down, the roller bracket (150) is linked and does not move. For this connection, a second long hole 1531 extending vertically is formed in the upper rail. In addition, an insertion screw 122 inserted in the horizontal direction is coupled to the upper rail 120, and the insertion screw is configured to pass through the second long hole 1531. Since the insertion screw 122 is inserted within the second long hole 1531, the roller bracket 150 moves together with the upper rail 120 in the horizontal direction, and the roller bracket 150 is bound to the slider 151. Even in this state, the upper rail 120 can independently move in the vertical direction.

The separation spindle 160 has one side fixed to the lower rail and the other side coupled to the roller bracket 150 to move the roller bracket 150 in the horizontal direction while supported on the lower rail. Specifically, the separation spindle 160 separates the upper rail 120 from the lower rail 110 so that the gangform coupled to the upper rail 120 separates from the outer wall of the structure.

This separation spindle 160 moves the roller bracket 150 away from or approaches the lower rail 110 while one side is fixedly coupled to the lower rail 110.

This separation spindle 160 includes a spindle body 161 and a moving screw 162. The spindle body 161 includes a support plate portion 1611 that extends long in all directions while fixed to the lower rail 110, and a screw that is fixedly coupled to the front of the support plate portion 1611 and has a thread formed on the inner peripheral surface. Includes a coupling portion 1612.

The support plate portion 1611 consists of a pair of thin bars spaced apart from each other and has a hole formed on one end thereof so that a screw connected to the lower rail 110 can be inserted through the hole.

The screw coupling portion 1612 is fixed to the front of the support plate portion 1611 and has a substantially cylindrical shape, with screw threads formed on the inner peripheral surface and fixed to the support plate portion 1611 on the outer peripheral surface.

One side of the moving screw 162 is coupled to the roller bracket 150 and the other side is screwed to the screw coupling portion 1612, so that when it slides along the screw coupling portion 1612, the roller bracket 150 moves together. It is done. This moving screw 162 consists of a tool fastening part 1621, a disk part 1622, and a screw part 1623. The tool fastening portion 1621 protrudes forward from the upper support 153 of the roller bracket 150 and can be coupled with a rotating tool carried by the worker. When the worker rotates the tool after binding it to the tool fastening portion 1621, the moving screw 162 can rotate.

The disk portion 1622 is configured to hang on the upper support 153 of the roller bracket 150 and rotate only within the partition wall 1532 of the upper support 153. The disk portion 1622 inserted into the partition wall 1532 of the upper support 153 is configured so that the moving screw 162 can rotate and is not separated from the partition wall 1532, so that the disk portion 1622 moves in the forward and backward directions. When moving, the upper support body 153 is also configured to move together with the disk portion 1622.

The screw portion 1623 extends from the disk portion 1622 and is coupled to the screw coupling portion 1612. Since the threaded portion 1623 is inserted into the screwed portion 1612 and screwed together, when the threaded portion 1623 rotates, it can slide in the longitudinal direction with respect to the screwed portion 1612. That is, when the screw portion 1623 rotates in one direction, the moving screw 162 moves forward, and when the screw portion 1623 rotates in the other direction, the moving screw 162 moves backward.

When the worker rotates the tool after binding the tool to the tool fastening portion 1621 of the moving screw 162 from the outside, the moving screw 162 moves forward and backward, and at the same time, the roller bracket 150 is also linked. It moves forward or backward. When the roller bracket 150 moves forward by rotating the moving screw 162 in one direction, the upper rail 120 and the gang form also move forward, and accordingly, the gang form coupled to the outer wall of the structure is configured to be demolded from the outer wall. do.

The separation prevention part 170 has one side installed at the lower part of the upper rail 120 and the other side coupled to the upper part of the lower rail 110, and regulates the upper rail 120 from moving in the lateral direction. will be. Specifically, the separation prevention unit 170 regulates the upper rail 120 from moving in a lateral direction rather than a designated path when moving forward for demolding of the gang form.

This separation prevention part 170 is formed in the form of a thin and long bar extending in one direction as a whole. A first through hole 171 is formed on one side of the separation prevention portion 170, and a first long hole extending long in one direction is formed on the other side.

A first screw screwed to the lower part of the upper rail 120 is inserted into the first through hole 171 of the separation prevention part 170, and a second screw screwed to the upper part of the lower rail 110 is inserted into the long hole. When inserted, the second screw can slide and move the first long hole when the upper rail 120 moves relative to the lower rail 110.

In this way, in a state in which the separation prevention part 170 is rotatably coupled to the upper rail 120, the second screw is inserted into the long hole, so the upper rail 120 can be guided along the longitudinal direction of the first long hole, so that the upper rail 120 (120) can only move forward with respect to the lower rail (110) and is suppressed from moving laterally at right angles to the horizontal direction.

In the gangform support 180, the insertion screw 122 can move in the vertical direction along the second long hole 1531, and in the upper rail 120, it can move relative to the roller bracket 150 in the vertical direction. The height of the upper rail 120 is adjusted so as to do so. In general, the work of raising the gangform is performed by the hydraulic cylinder 200, but the bottom part of each structure may have a different height, and it is not easy to precisely adjust the height of the gangform in the field using only the hydraulic cylinder 200. In addition, the hydraulic cylinder 200 increases the overall height of the gangform, but there is a limit to precisely aligning the gangform to the desired position. In the present invention, the gang form support 180 is installed so that the worker can adjust the position of each gang form in detail while visually observing it.

This gangform support 180 consists of a support body 181, a protrusion 182, and an elevating member 183.

The support body 181 is fixedly installed on the upper rail 120 and is configured to be fixed in position by being inserted into a screw installed on the upper rail 120. This gang form support can have a structure in which a hole is formed in an “I” shape, but is not limited to this.

The protrusion 182 protrudes forward from the support body 181 and includes a protrusion plate 1821 composed of a thin rectangular plate placed horizontally, and a protrusion plate 1821 that stands perpendicular to the protrusion plate 1821 and has threads formed on the inner peripheral surface. It is configured to include a protruding screw portion 1822. A screw thread is formed on the inner peripheral surface of the protruding screw portion 1822, and a hole connected to the inside of the protruding screw portion 1822 is formed in the protruding plate 1821 to allow the lifting member 183 to pass through the hole.

The lifting member 183 is screwed to the protrusion 182 so as to be movable in the vertical direction. This lifting member 183 has a hexagonal bolt head shape at the top so that a tool can be coupled to it, and is configured to have threads formed on the outer peripheral surface below it.

The bottom of the lifting member 183 is in contact with the upper part of the roller bracket, and when the lifting member 183 descends, the upper rail 120 moves in a direction away from the roller bracket 150. When the worker rotates the lifting member 183, the lifting member 183 descends and moves the upper rail 120 away from the roller bracket 150, allowing the height of the gangform to be precisely adjusted.

The fall prevention unit 190 has a fall prevention position on the upper part of the lower rail 110 to prevent the hook unit 132 from being separated from the lower rail 110, and the hook unit 132 is located on the lower rail (110). It moves between release positions that allow it to be separated from 110).

This fall prevention unit 190 includes a pair of swing plates 191 and a locking pin 192.

The swing plate 191 is made in the form of a thin plate and is placed in a pair spaced apart from each other. One swing plate 191 is rotatably coupled to one side of the lower rail 110, and the other swing plate 191 is rotatably coupled to the other side of the lower rail 110.

The center of the swing plate 191 is rotatably connected to the lower rail 110. A locking pin 192 is coupled to one free end of the swing plate 191 so as to pass through the spaced interior, and a lower part is attached to the other free end of the swing plate 191 so that the swing plate 191 is positioned and fixed in the fall prevention position. A fixing hole 1911 is formed into which a fixing screw 112 screwed to the rail 110 is inserted.

As shown in FIG. 9, when the swing pin is placed in the release position that opens the upper part of the lower rail 110, the guide shoe 130 is attached to the lower rail 110 without releasing the gang form. After the guide shoe 130 is inserted into the lower rail 110, the swing pin rotates about the center and rotates to the fall prevention position, so that the lower rail 110 is caught even if it falls. Stability can be secured by allowing the pin 192 to be caught on the hook portion 132 of the guide shoe 130. In the fall prevention position, the worker can restrict the guide shoe 130 from moving to the release position by fastening the fixing screw 112 to the lower rail 110 through the fixing hole 1911.

A method of constructing a structure using the gangform lifting system 100 according to the present invention will be described with reference to FIGS. 11 to 15.

Figure 11 shows the state before lifting the gangform using the gangform lifting system 100, and at this time, part of the structure has completed construction.

Figure 12 shows the step of separating the gangform from the structure, and the worker separates the gangform from the structure using the separation spindle 160. Specifically, when the tool is inserted into the moving screw 162 and the moving screw 162 is rotated, the roller bracket 150 is guided by the rail bracket 140 and moves in the horizontal direction.

Figure 13 shows the gang form being lifted upward using the hydraulic cylinder 200. The hydraulic cylinder 200 is supported on the guide shoe 130 at the lower end, and the upper part hangs on the lower rail 110. When the rod is extended while the hydraulic cylinder 200 operates, the lower rail 110 is raised one floor higher. It will rise accordingly. When the lower rail 110 rises, the upper rail 120 also moves upward while being spaced apart from the outer wall of the structure.

Figure 14 shows the guide shoe 130 being installed at the top of the structure. In order to bind the guide shoe 130 to the lower rail 110, the fall prevention unit 190 is moved to the dismantled position. In the released position, the guide shoe 130 can be easily inserted into the lower rail 110 even without dismantling the gang form.

Figure 15 shows that the guide shoe 130 is installed at the top of the structure and coupled to the lower rail 110, and the fall prevention unit 190 is rotated to the fall prevention position to prevent the lower rail 110 from falling. Shows the ordered state.

Afterwards, additional parts of the structure are constructed using the gang form as a formwork, and construction is carried out by repeatedly performing the steps shown in Figures 11 to 15.

Previously, when using a guide shoe, there was a problem of the concrete filling phenomenon occurring due to the gangform open section during concrete pouring due to the gangform being opened separately. In addition, when installing the guide shoe, it did not function as a safety pin, so there was a problem of falling if a problem occurred in the middle shoe supporting the load.

On the other hand, the present invention has the advantage that the fall prevention part plays a role in preventing the guide shoe located at the top from falling, and there is no need to open a separate gang form, so the phenomenon of fullness does not occur when pouring concrete.

In addition, the fall prevention part facilitates the installation of the guide shoe by removing the fixing pin when installing the guide shoe on the upper side and rotating it into a hinge type, and increases stability by fastening the fixing pin after installing the guide shoe. In particular, it has the advantage of being able to prevent falls in case of a problem with the middle shoe due to the role of the upper safety pin.

In the above-described embodiment, it is exemplified that the horizontal rail portions of the rail bracket 140 are spaced apart from each other and the lower center is open downward, but this is not limited to this and has a “ㄷ” shape as shown in FIG. 16. It is also possible that a reinforcing plate 143 is added to the horizontal rail portion 142 to connect a pair of floor plates 1421 spaced apart from each other. The reinforcement plate 143 may be joined to the bottom plate 1421 by welding, or may be coupled to the bottom plate 1421 by bolting or rivets. In this way, when the open space between the floor plates 1421 is sealed by the reinforcement plate 143, it prevents gang foam or falling objects generated from the upper part from passing between the floor plates 1421 and falling to the ground, resulting in casualties. can do.
