[Technical field to which the device belongs]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building form panel connecting device, and more particularly to a building form panel connecting device that is convenient to operate and can quickly connect and dismantle adjacent frame panels.

[0002]

[Prior art]

 Instead of wood formwork, metal foam formwork has come to be used in most large-scale construction works because metal foam formwork has a smooth surface and can be used for a long time. This is because there is an advantage, and as shown in FIG. 1, which is a local structure diagram of a metal foam formwork of a conventional example, the metal foam formwork has a length of a long plate in accordance with the standard required at the construction site. In this case, panel units 1 with different widths are connected in parallel, and the total wall width to be constructed differs at different construction sites. Therefore, when these panel units 1 are connected in parallel and combined, panels with different widths are combined. The units 1 are appropriately combined and arranged to form a formwork panel having the required full width.

In the construction work of a large number of buildings of the same type, for example, condominiums, high-rise buildings, housing complex, etc., the interior floor plan of each house is designed to the same standard, and standardized into a unit. Since the same set of formwork panels can be used repeatedly, there is no need to constantly change the size of formwork panels.

At the beginning of erection of the formwork, since the formwork panels of those standardized units can be carried to the formwork erection site by the hoist, it is not necessary to subdivide and disassemble the formwork panel, When the molding is completed and cured and solidified, the standardized unitized form panel in the room, that is, each member of the form panel on the inner wall surface, must be dismantled, moved out of the building, and re-combined for repeated use. However, under the condition that the four side walls in the room are already completed and almost closed, it is impossible to remove these standardized formwork panels together with each member from the floor bottom and carry them out of the building. There is no choice but to dismantle it into an appropriately small frame panel, carry it out of the building through the windows and doorways left on the four-sided peripheral wall, and combine it again for reuse.

In order to save manpower and time required for disassembling and reassembling, it is not necessary to dismantle each form panel into the long plate-shaped panel unit 1, and for example, 3 to 4 that can be carried out from a window or a doorway. It suffices to disassemble one panel unit 1 to a size in which it is connected in an array. In the process of repeating this disassembling and reassembling, each panel unit 1 can be operated quickly and improves work efficiency. It is desirable that the design of the parallel connection part 1 be simple, solid, and easy to assemble and disassemble.

Further, in dismantling the formwork panel, the panel surface portion of the entire formwork is adhered to the solidified concrete surface, and the adhesion of the two causes difficulty in detaching the formwork, and therefore dismantlement It is desirable that the panel surface of the form can be quickly separated from the concrete surface under the condition that it is easy.

[0007]

[Problems to be solved by the device]

 In light of the above-mentioned problems which are urgently desired in the conventional connecting device for building form panels, the present invention enables quick and convenient assembly and disassembly by manual operation, and adjusts the degree of parallel joining of both adjacent panel units. It is an object of the present invention to provide a connecting device for a formwork panel for construction, which can form a smoother panel surface.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides first and second connecting plates that are bent and extended rearward at an appropriate angle so as to form a complementary angle by closely contacting the connecting side edges of both adjacent panel units. Portions are integrally formed, and at least a pair of first and second connecting holes having the same width and length that can correspond to each other are provided in the first and second connecting plate portions, and are connected to both the connecting holes. By inserting the sandwiching locking portion formed at one end of the body and appropriately rotating the connecting body, the rotation amplitude along the major axis of the sandwiching locking portion pushes both connecting holes sideways. The hole walls of the two connecting holes are made to correspond to each other, and at the same time, the engaging plate and the engaging surface of the engaging neck portion provided on the sandwiching and engaging portion tightly sandwich and sandwich the connecting plate portions at the connecting hole portions. Then, the two adjacent panel units are quickly connected to each other.

Then, for example, if connecting holes are formed in the first and second connecting plate portions and are bonded and communicated in a corresponding manner without displacement, the panel surface portions of both the adjacent panel units have the same smooth surface. The surfaces are connected to each other, and this state is firmly held by the engaging neck portion of the connecting body, or the first and second connecting plate portions are respectively attached to the respective end edges by adhesive hooks. If a second hook portion is provided and the first and second hook portions are adhesively hooked to each other, the panel surface portions of both adjacent panel units have the same smooth surface and are connected to each other, and It is more preferable to devise various means for each member, such as making it possible to hold the state by hooking with a holding means.

According to the present invention constructed as described above, when the first and second connecting plate portions are attached to each other and the respective connecting holes are communicated with each other substantially correspondingly, one end of the connecting body is connected. Inserting the holding head portion and the engaging neck portion into the both connecting holes, rotate the grip handle downward by 90 degrees with the holding head portion protruding from the other side surface of the both connecting holes. The clamping surface and the locking surface to clamp both the connecting plate portions, and the engaging neck portion is rotated in the both connecting holes with the swing amplitude along the major axis thereof. By completely matching and matching, the panel surface portions of both adjacent panel units can be quickly connected and held to the same smooth surface.

[0011] On the other hand, when the floor concrete casting is completed and the form is removed, if both the panel units are relatively displaced by loosening and removing the connecting body in the opposite direction, the both panel surface portions are difficult. It can be easily and quickly removed from the concrete wall without the need for a method.

Further, in order to enhance the effect of the connection and smooth joining of the both panel units, the first and second hook-stop portions which are hook-joined to each other by the pinching inlet of the pinching means are pinched and pinched, and The final end is hooked to the inner curved surface of the hook of the first hook, and the grip handle is rotated to connect the first and second hooks to the end and the arcuate step. It is sufficient to clamp the delivery handle between them and the grip handle can be quickly and easily released by rotating the grip handle in the opposite direction.

[0013]

The second panel unit 4 is similarly formed by aluminum extrusion molding. As shown in FIGS. 3 and 4, the second connecting plate portion 42 integrally formed with the second panel unit 4 is the first panel. It is similar to the first connecting plate portion 32 of the unit 3, and the difference between the two is that the angle direction in which the second connecting plate portion 42 integrally extends in the rearward oblique direction from the side edge of the panel surface portion 40 is the above. When the first and second connecting plate parts 32, 42 are brought into contact with each other in a complementary relationship with the first connecting plate part 32, the respective panel surface parts 30, 40 are joined to form an integral plane. In addition, the three connecting holes 43, 44, 45 of the second connecting plate portion 42, including the shape thereof, are almost the same as the three connecting holes 33, 34, 35 of the first connecting plate portion 32. Corresponding and correspond respectively to communicate.

As shown in FIGS. 4 and 5, the positional relationship between the upper and lower edges of the panel unit and the side edges of the panel surface of each connecting hole is as shown in FIGS. 4 and 5, respectively. When 431 communicates in correspondence with each other without displacement, the joint lines 301 and 401 of the panel surface portions 30 and 40 are in anastomosis with each other without any displacement, and the horizontal line sighting connection hole 34 is formed. When the hole walls 341 and 441 of the panel units 44 and 441 are in communication with each other in correspondence with each other, the upper and lower edges 302 and 402 of the panel units 3 and 4 are exactly on the same level plane, and the above-mentioned two pairs. Under the condition that the connecting holes 33, 43, 34, 44 of No. 3 are communicated in an anastomotic manner without displacement, the longitudinal center line of the mold contraction connecting hole 35 is slightly different from the other connecting holes 34, 33. Out of alignment and therefore both formwork When the contraction connecting holes 35 and 45 are communicated with each other and the hole walls 351 and 451 are displaced from each other by a predetermined amount, the joining lines 301 and 401 of the panel surface portions 30 and 40 are joined to each other without any deviation. In addition, a second hook stopper 46 having an inner hook curved surface 461 and an outer hook curved surface 462 is formed at the end edge of the second connecting plate portion 42, and the second hook stopper portion 46 is formed. Allows the hook to be engaged with the outer hook curved surface 362 of the first hook stopper 36.

The cross-section P1 of the engagement neck portion 52 has a shape similar to an ellipse with both edges rounded in an arc shape, and when rotated, the maximum rotation amplitude W1 is obtained by the long axis, and the rotation angle W1 is increased. The oscillating width W1 is set to be just equal to the minor axis dimension, that is, the width of the connecting holes 33, 43, 34, 44.

The holding head portion 53 has two planes parallel to each other across the distance X and extending in the same direction as the major axis of the engaging neck portion 52, and has convex edge portions 531 formed at both ends thereof. A locking surface 532 is provided at a connection portion with the engaging neck portion 52, and a diameter width X between both side surfaces different from the convex edge portion 531 of the holding head portion 53 is set to a width of each of the connecting holes 33, 43, 34, 44. It is convenient to insert it into the connecting hole by making it smaller than the degree and making the dimension Y between the tips of the convex edge portions 531 slightly smaller than the major axis of the connecting holes 33, 43, 34, 44. To do so.

Among them, the axial length of the engaging neck portion 52, that is, the distance Z from the locking surface 532 to the holding surface 510 is approximately the thickness of the first and second connecting plate portions 32 and 42, respectively. The grip handle 50 is provided equally to the sum, and the grip handle 50 has a longitudinal direction in the same direction as the major axis of the engaging neck portion 52.

As shown in FIGS. 8 and 9, the second connecting body 6 has a grip portion 60, a holding base portion 61, an engaging neck portion 62, and a holding head portion as in the case of the first connecting body 5. 63, the related positioning forms of the respective parts are substantially similar, but since they are designed corresponding to the above-mentioned both mold contraction connecting holes 35, 45, the both connecting holes 35, 45 are not yet joined. Shows a state in which they are partially overlapped with each other, and the gap between the vertical hole walls 351 and the hole wall 451 on the opposite side is narrowed. The first connecting body 5 of 6 is provided in the shape of a flat cone that is obliquely cut out from the top end of the holding head 53 so that it can be easily inserted into both connecting holes 35 and 45 that are narrowed by a predetermined distance. At the same time, the rotation amplitude W2 of the engagement neck portion 62 is set to the hole wall 351 of the connecting holes 35 and 45. And the hole wall 451 are provided with the same width as the body surface, and the cross-sectional shape of the engaging neck portion 62 is changed to a shape shown in FIG. Make it convenient to turn. The grip handle 60 is provided in a longitudinal direction orthogonal to the swing amplitude W2 of the engaging neck portion 62 along the major axis.

As shown in FIG. 10, the sandwiching means 7 comprises a grip handle 70 and a clamp portion 71 formed at one end of the grip handle 70 and having an elastic shape and curved in a hook shape. A starting end portion 72 extending from one end of the grip 70 in a predetermined curve in an asymptotic curve shape, an arcuate step portion 73 connected to the starting end portion 72 and extending an appropriate distance in an arc shape having a predetermined radius of curvature; A curved step portion 74 connected to the step portion 73 and gradually extending toward the starting end portion 72 by a predetermined distance and forming a sandwiching inlet 75 between the end portion 741 and the starting end portion 72; A terminating end that is provided at the end of the curved step portion 74 and has an arc surface 76 1 parallel to the arc step portion 73 at a position opposite to the start end portion 72 and the arc step portion 73. And part 76.

Among them, the distance between the front inner surface 731 on the inner surface of the arcuate step 73 and the corresponding arcuate surface 761 of the end end 76 is relatively long, and the inner surface of the arcuate step 73 is relatively long. The distance between the middle inner surface 732 and the corresponding arcuate surface 761 of the end portion 76 is relatively short, and the middle inner surface 732 of the arcuate step portion 73 has an arc surface of the end portion 76. At least one location T1 is provided so that the distance from the location 761 is equal to the vertical distance of the maximum thickness T2 when the first and second hook portions 36 and 46 are engaged with each other, and from that location T1. When entering the back, a tight holding pin is formed so that the distance between the middle inner surface 732 of the arcuate stepped portion 73 and the arcuate surface 761 of the end end portion 76 becomes smaller. In particular, it is formed in the shape of a ridge to enhance its sandwiching function.

With the above-described structure, as will be understood by referring to FIGS. 5 and 11, when the present invention is used, the connecting holes 33 and 43 and the first connecting body 5 will be described as a representative example, when the first and second connecting plate portions 32 and 42 are adhered and abutted to each other so that the connecting holes 33 and 43 substantially communicate with each other. Inserting the holding head portion 53 and the engaging neck portion 52 at one end of the first connecting body 5 into the connecting holes 33 and 43, the holding head portion 53 is located on the other side surface of the connecting holes 33 and 34. The grip handle 50 is rotated downward by 90 degrees under the state of protruding so that the connecting plate portions 32 and 42 are clamped by the clamping surface 510 and the locking surface 532. The neck portion 52 is rotated in the connecting holes 33 and 43 with the rotation amplitude W1 of each of the holes. When the walls 331 and 431 are in complete communication, the purpose of connection and anti-matching is achieved, and the joining lines 301 and 401 of both panel face portions 30 and 40 are surely anti-matching.

Similarly, if the second first connecting body 5 ′ is used for the horizontal aiming connecting holes 34 and 44, the upper and lower edges of the panel units 3 and 4 are matched at the same level. be able to.

On the other hand, the mold shrinkage connecting holes 35, 45 have already been connected to the perpendicular aiming connecting holes 33, 43 and the horizontal aiming connecting holes 34, 44, and both panel surface portions 30, 40 are Forming two smooth surfaces, the mold can be contracted during the process of erection and dismantling the form.

For example, as shown in FIG. 2, the supporting devices of the present invention are provided at the central portions of the four side walls of the enclosure-shaped slab form 2, that is, the panel units 3 and 4 are enclosed. When the slab formwork panel 2 is attached to the inside of the concrete wall 20 below the four side walls, as shown in FIGS. 12 and 13 (of which FIG. 13 is a bottom view), first the second connecting body 6 is placed on the ground. When both panel units 3 and 4 are relatively displaced by inserting them into the connecting holes 35 and 45 and twisting and turning them so that the hole walls 351 and 451 of the connecting holes 35 and 45 respectively correspond to each other. Since the units 3 and 4 are in contact with each other in an oblique direction, when one panel surface portion 30 droops and retracts vertically due to the corresponding movement of the inclined surface, the other panel surface portion 40 is interlocked and horizontally moves slightly horizontally, At this time, the metal part Since the material is somewhat flexible, the lower end of the enclosure formed by the entire wall beam panel 22 retracts slightly inward, and although the degree of the retraction is not large, the accuracy of the construction work is required. Under such circumstances, a marginal space is formed at the lower end of each wall beam panel 22, so that it can be relatively easily fitted into the inside of the upper edge of the concrete wall 20 that is closed on all sides, and the entire slab formwork 2 is suspended and suspended. Work becomes convenient.

Then, after the whole slab formwork 2 is fixedly installed on the upper end of the concrete wall 20, the second connecting body 6 is twisted and turned in the reverse direction so that the respective panel surface portions 30 and 40 correspond to the same smooth surface. It recovers to the state where it did.

On the contrary, when the concrete casting of the floor is completed and the form is removed, first, both the first connecting bodies 5 and 5 ′ are loosened in the opposite direction and then the second connecting body is removed. When 6 is twisted and rotated once again to relatively displace both panel units 3 and 4, both panel surfaces 30 and 40 are forcibly concreted by a simple operation without the need for another difficult method. Get off the wall.

As shown in FIG. 10 (bottom view), the holding means 7 is used to enhance the effect of the connection and smooth joining of the both panel units 3, 4, and when used, first, the holding means 7 is used. The first and second hook-stop portions 36 and 46 which are hook-joined to each other at the inlet 75 are pinched and sandwiched (see FIG. 4), and the end end portions 76 thereof are fitted into the hook-inside curved surface 361 of the first hook-stop portion 36. The grip handle 70 is rotated, and the first and second hook stoppers 36 and 46 are delivered and clamped between the end end 76 and the arcuate stepped portion 73 for connection. At the same time as achieving the purpose, it is easy if both panel units 3 and 4 are securely sandwiched to hold the respective panel surface portions 30 and 40 on a smooth surface and the grip handle 70 is rotated in the opposite direction. The holding state can be released, and the holding means 7 rotates the second connecting body 6 by loosening it. It is used in this case, and surely exerts a predetermined sandwiching and holding function, and firmly holds the smooth surface formed by the panel surface portions 30, 40.

As described above, the feature of the present invention is that one connecting member may be disposed in a pair of connecting holes of both panel units 3 and 4 facing each other, or as shown in the drawings and the embodiment. In addition, it is also possible to use two connecting bodies arranged in three pairs of connecting holes.

That is, the operation of the present invention is diverse, and for example, as in another embodiment of the present invention shown in FIG. 14, the connecting holes 33 ', 43' of the pair are connected to the connecting holes 35 of the other pair. By slightly deviating to a degree smaller than the deviation of ', 45', the mold retracting connecting holes 35 ', 45' are forcibly made to correspond to the hole walls 351 ', 451' by the second connecting body 6. In this case, the bottom portions of the panel units 3 and 4 may be relatively displaced so that the panel units 3 and 4 are not excessively bent. In this embodiment, the horizontal aiming connecting holes 34 'and 44' are first provided. The first connecting member 5 is used to match the hole walls with each other, and then the mold retracting connecting holes 35 ', 45' are used with the second connecting member 6 to match the hole walls with each other. Due to the deviation, the second connecting body 6 is finally used for the sighting of the two perpendicular lines in which the hole walls are already close to the corresponding coincidence. It is inserted into the connecting holes 33 'and 43' to achieve the purpose of sandwiching and connecting as shown in FIG.

At this time, the bottom of the enclosure-shaped slab form 2 can be easily retracted inward to fit inside the upper ends of the four-way peripheral wall, and the three connected bodies can be connected after the formwork is completed. All 5 and 6 are loosened and removed, and instead, both panel units 3 and 4 are clamped and fixed by three clamping means 7, and both panel surface portions are secured to one smooth surface.
