Description

  The present invention is a metal fitting for fixing the inner width of the previously built formwork, and one of the two separators connected to the female screw hole at the tip of the peakon fixed to the formwork on both sides. From the front of the U-shaped opening of the Sepalock fitting main body of the U-shaped configuration on the side surface of the position where the other end of the separator is doubled and fixed, by screwing the male screw at the end to the two sides. It is a metal fitting that is wrapped around the side surface of a doubled separator and fastened and fixed at once by the side surface of the tightening slope shaft.

  The clamping ramp axis is a clamping ramp axis with a hexagonal head fixed to one of the shaft bases, and the angle from the part straight to the tip of the shaft is fixed at the angle of the clamping ramp axis. The screw projection rough screw is fixed to the outer periphery of the tightening slope shaft, and a part of the tip of the tightening slope shaft is fixed to the screwless shaft portion.

Background technology

  In a conventional metal fitting for connecting a separator, the male screw shafts of one of the two separators to be connected are screwed into a female screw cylinder in a cylindrical metal fitting of a female screw, Although there is a method in which the male screws are abutted and fixed in a single unit, this connection method has a limitation on the length of each one with respect to the length of the separator to be connected.

  The structural configuration of the commonly used separator coupling metal fittings is an elliptical cylindrical configuration, with an elliptical through hole or a round through hole fixed at the center of the elliptical cylindrical metal fitting. When connecting a separator by passing a shaft pin through this through hole, the shaft pin in the elliptical cylindrical hole is used as a core, and the separators connected to both sides of the core are staggered from both holes. Insert and insert both separators back and forth in the axial direction of the separator to determine the length, and depending on whether the shaft pin in the core is pushed in strongly or pulled, it varies depending on the manufacturer. Also in the method, two separators that are connected in an elliptical cylindrical hole are firmly inserted between the separators with an axial pin, and the separators are spread out on both sides and pressed against the circular wall. How to fix this separator If widely between the separator and the separator, the more separators fitting is twisted when pulling the end portion of the separator is the separator becomes brittle cutting.

  In the conventional separator connection brackets, all separators are passed through the holes and the separators are fixed. The separator is fixed by wrapping the separator with the separator connection brackets from the side of the separator shaft. Since the metal fitting to be used is not found in the past, it takes a very long time to connect the separator, and until the length of the separator to be connected is determined and fixed. It takes a very long time. The reason is that the two separators to be connected move back and forth in the connection fitting, so when measuring the length of the separator, there is no standard thing, so it will not be stable until any time, so it will be adjusted to the middle Things are difficult.

  In the conventional shaft screw relationship, when tightening or loosening an object, all screw relationships are rotated clockwise or counterclockwise in the vertical direction of the screw shaft, and the object is moved by the screw shaft. It was tightened.

When two separators are connected to one with the structural configuration of the conventional separator connection bracket, the shaft pin is inserted between the two separators to be connected, and the two separators are attached to the walls of the connection bracket on both sides. The two separators are fixed at the same time.
In the structure where a space is provided between the separators by the connection method as described above, when both ends of the separator are pulled with a strong load, the strength against which the separator is pulled on both sides The connecting metal part of the separator is twisted, and the separator may be cut without applying sufficient force to the connected separator.

  In conventional beam separators, beam forms are assembled and peakons are attached to the beam side molds on both sides, and the slab is placed on the entire beam side form, and then the rebar construction is started. After the construction is completed, screw the beam separator hook metal fitting into the hole in the peakon attached to the beam side, and then insert one side L-shaped of the U-shaped beam separator into the hole of the beam separator hook metal fitting. After hooking, the L-shaped one end of the remaining separator is also hooked through the hole of the beam separator hook metal fitting on the other side in the same manner as described above, thereby completing the installation of one beam separator. However, it is necessary to attach several hundred beam separators to the number of beam separators to be attached to the slab beams for the first floor in the same manner.

  However, depending on how the slab is stretched, the beam width dimension can be slightly deviated. For example, if the beam width increases by 5 mm, the normally ordered separator is shortened and cannot be used. Or, conversely, if the beam width is reduced by 5 mm, the beam separator shaft is bent sideways, the gap width of the U-shaped beam separator is matched, and it is hooked through the hole of the beam separator hook fitting. However, in any case, it is work after the beam rebar and slab rebar are completed, so the U-shaped beam separator is passed through the hole of the beam separator hook fitting until it is completed This is a difficult and time-consuming task.

Of the construction work, the formwork work is particularly important in the overall work. For that reason, from the beginning, the work of the formwork is based on the budget amount of the work and the building of the first floor formwork. The schedule for placing concrete is clearly incorporated into the process.
Because of the above, when building a formwork, it is necessary to reduce the budget, and to do the work so that the work proceeds accurately and quickly, but to do so In particular, the metal fittings of the formwork required for the building relations of the formwork is an important problem.

  In order to achieve the above object, the present invention provides a U-shaped separlock metal fitting body and a screw projection rough screw tightening slope shaft, which are fixed to provide a U-shaped separlock metal fitting body (1). The space between the U-shaped opening (7) and the U-shaped inner wall (6) is a space, and the side surfaces of the two separator shafts (30) extend from the U-shaped opening (7) to the U-shaped inner wall ( 6) After contacting the side surface of the U-shaped separator lock metal fitting body (1) from the large diameter upper hole (2) to the left hole rod of the small diameter pilot hole (3) The screw-less shaft (13) of 11) is inserted, and for the first time at this time, the U-shaped opening (7) is blocked by the tightening inclined shaft (11).

  The U-shaped separlock metal fitting body (1) has a U-shaped configuration on the side surface where the two separators (30) to be connected doubly overlap each other regardless of the length of the separator. From the front of the U-shaped opening (7) of the separlock metal fitting body (1), wrap it in the side of the two separators (30) to be connected and feed it straight to the side of the U-shaped inner wall (6) Thus, it is a U-shaped separlock fitting in which the two separators (30) that are connected at the same time on the side surface of the tightening inclined shaft (11) are locked and firmly fixed.

  The U-shaped separlock metal fitting body is bent and fixed to the two U-shaped inner walls of the semicircular shape (6) of the separator shaft (30) from the longitudinal center of the rectangular iron plate. A large diameter upper hole (2) and a small diameter lower hole (3) through holes are fixed and fixed closer to the opening (7) side than the center of the iron plate that is bent and fixed to the two inner walls of the mold The tip of the left hole の of the hole and the small diameter pilot hole is a substitute for the female screw of the screw projection rough screw (12) of the tightening inclined shaft (11), and the left hole 淵 (2) and (3) are the female screw. As a result, the tightening slope shaft has been greatly utilized, and the U-shaped separlock metal fitting body and the tightening slope shaft are completed.

  As for the tightening slope shaft, a hexagon head (14) is fixed to one of the bases (10) of the tightening member, and a neck (15) for attaching a connecting string is provided between the hexagon shaft and the base. Fixed, a part of the shaft base (10) is fixed directly, and the tightening slope shaft (11) with an inclination angle from the straight position to the tip of the shaft is fixed, and the screw projection rough screw (12 ) Is fixed, and a part of the tip of the slope shaft is fixed to the screwless shaft portion (13). The distance between the screw projection and the projection is the thickness of the U-shaped separok fitting body metal fitting, The interval width of the protrusions is fixed.

  The above structure is an explanation of the structural content of the U-shaped separlock metal fitting body (1) and the tightening slope shaft of the screw projection rough screw (12). To explain briefly, for example, for the beam-side formwork, once the assembly of the beam-side formwork is finished, when the peakon is attached and fixed to the beam side at the same position on both sides, the beam is immediately The slab is stretched with a panel panel on the entire surface of the upper side of the side, and the upper side of the beam side is completely fixed by nailing to the slab plate. After the installation, the slab rebars are installed on the grid on the entire surface of the slab, and after the rebar construction is completed, the beam separator is attached to the beam side and fixed. Since the work is performed after the The female screw hole of Pikon you have, be fixed by mounting the beam separator regular size is medium people difficult.

  However, both the beam and the slab are fitted with a regular length into the female screw hole of the PECON that is fixed to both beams by inserting one arm into the narrow gap between the reinforcing bar and the reinforcing bar. Since it is impossible to screw and fix the male screw of the separator, the present invention does not depend on the length of the separator, and the male screw (31) at one end of the separator having an appropriate length is Screwed into the female threaded holes of the peaons on both sides and fixed to the side of the two separators (30) where one end of the two separators (30) overlaps and is doubled. 1) From the front of the U-shaped opening (7), wrap the double-sided side of the separator and press the side of the separator (30) into the side of the U-shaped inner wall (6) Remove the screwless shaft (13) of the slope shaft (11) from the upper hole (2) to the lower hole ( ), And the hexagon head (14) of the tightening slope shaft is rotated to the right. The double overlapped two separators are locked at once and strongly fixed. Since there is a separate separlock metal fitting, the beam separlock metal fitting with a U-shaped configuration can be used as long as the opening is in a state where one arm can be inserted, no matter how narrow the opening is.

  The U-shaped normal separlock metal fitting body and the U-shaped beam separlock metal fitting body have the same structure, but the only difference is the U-shaped normal separlock metal fitting body. Is required to be stronger than the U-shaped beam separator lock metal fitting, so that the thickness of the iron plate of the metal fitting itself and the female screw member (20) are fixed to one upper end of the U-shaped inner wall (6). .

  The U-shaped separlock metal fitting body according to the present invention is a separator in which the connecting portions of two separators to be connected are overlapped, the separators and the side surfaces of the separator are in contact with each other, and the separators are overlapped Wrap the side of the separator in a stacked state directly from the U-shaped opening of the U-shaped separlock metal fitting body into the side of the U-shaped, and push it straight into the side of the U-shaped inner wall, Insert the screw tightening slope shaft between the upper hole from the upper hole of the U-shaped Sepalock fitting body to the left hole 下 of the lower hole and the right side between the left side of the separator, and rotate the hexagonal head clockwise. The two separators are U-shaped separlock fittings that are locked at once and strongly fixed. The outer periphery of the tightening slope shaft is a screw protrusion rough screw, so even if it is lightly tightened, Speed Ku and a Separokku fitting of the U-shaped structure of stabilized the method tightening.

The U-shaped separlock metal fitting of the present invention is a very excellent product in which the traction force of the connected separator is stronger than the conventional metal fittings, but it is a product with only two types of parts. In addition, the product is produced at a low production cost.
In addition, since the protruding ends of the large-diameter upper hole and small-diameter pilot hole of the U-shaped Sepalock fitting body are substitutes for female screws, there is no need to newly produce female screws. The material cost and labor cost are 0 yen, and even if it is produced in Japan, it can be sold at a price lower than the selling price of conventional separator fittings. The feature of the U-shaped separlock metal fitting body of the present invention is that even if the separators are ordered collectively, the length of the ordered separator is not wasted. If there are other separators in the field, the size is not related. For example, if the size of the separator is long, even if the separator is cut in half, the female screw is fixed to one end of the separator. Is used, Invention is, in the current recession era, and the fast of the work, as oriented at a low cost and economic thing of the product, but the product of stable configurations have been proposed excellent.

The separator lock metal fitting body of the U-shaped configuration of the invention is in a state where the center part of the side surfaces of the two separators to be connected from the beginning is overlapped, and the total length of the separator is positioned, it is overlapped As it is, wrap the side of the separator in a state where two overlap each other from the front of the U-shaped opening of the U-shaped Sepalock fitting body on the side of the separator. A U-shape that uses the tightening slope shaft of the screw projection rough screw that pushes into the side surface of the inner wall and fastens the side surface of the two overlapping separators at once with the side surface of the tightening slope shaft of the screw protrusion rough screw U-shaped structure that can be expected to finish work faster because the force of tightening at the side of the inclined shaft of the screw protrusion rough screw is fast and the speed of tightening is fast. This is a separoc metal fitting.
