Definitions

  • the present invention relates to a ferroconcrete constructing frame. More particularly, it relates to a ferroconcrete constructing frame for winding around reinforcing steels forming a pillar or similar structural parts in reinforced concrete buildings, bridges, or similar structures.
  • prior ferroconcrete constructing frame has been constructed in the way that profile steel or similar bar of 10 or 13 mm thick having ring-like convex and concave is cut out to desired lengths, which are combined laterally and longitudinally or vertically around a beam or similar structural part to form a constructing frame by binding them at the crossing points with wires, belts, or the like.
  • the ferroconcrete constructing frame comprising a constructing frame having four side frames linked together to surround a beam forming a pillar or similar structural parts, each of the side frames being independent from the other and comprising a plurality of lateral bars and a plurality of longitudinal bars perpendicular to the lateral bars, cross points of the lateral bars and longitudinal bars being welded to fix.
  • the constructing frame is formed on site in a way that the lateral bars have a ring formed on a plane perpendicular to the longitudinal bars at each of ends thereof, and that rings of one side frame are made to align the ones of an adjoining side frame, and that a stick bar is passed through the aligned rings to link the side frames.
  • lateral bars of the side frame have a ring formed on a plane perpendicular to the longitudinal bars at one end thereof and a hook formed on the plane at the other end
  • the constructing frame is formed on site in a way that the lateral bars have a ring formed on a plane perpendicular to the longitudinal bars at each of ends thereof, and that the rings of one side frame are made to align the ones of an adjoining side frame, and that a stick bar is passed through the aligned rings to link the side frames, and that the hooks are made to hook the stick bar passed through the rings of the adjoining side frame.
  • lateral bars of the side frame have a ring formed on a plane perpendicular to the longitudinal bars at one end thereof and a hook bent from the longitudinal bars on a plane parallel with the lateral bars at the other end, and the constructing frame is formed on site in a way that the lateral bars have a ring 8 formed on a plane perpendicular to the longitudinal bars at each of ends thereof, and that the rings of one side frame are made to align the ones of an adjoining side frame, and that a stick bar is passed through the aligned rings to link the side frames, and that the hooks are made to hook the rings of the adjoining side frame.
  • bars of the side frame have a hook formed on a plane perpendicular to the longitudinal bars at each of ends thereof, and the constructing frame is formed on site in a way that the hook on each end of the side frame is made to hook the respective stick bars passed through the rings of the adjoining side frames on both sides thereof.
  • lateral bars of the side frame have one hook at each of ends thereof, which are bent reversely from each other on a plane parallel with the lateral bars, and the constructing frame is formed on site in a way that the hook on each end of the side frame is made to hook the respective rings of the adjoining side frames on both sides thereof.
  • lateral bars of the side frame have a hook formed on a plane perpendicular to the longitudinal bars at one of ends thereof and a hook bent from the longitudinal bars on a plane parallel with the lateral bars at the other end, and the constructing frame is formed on site in a way that the hook on one end of the side frame is made to hook the stick bar passed through the ring at a free end of the adjoining side frame, and that the hook on the other end of the side frame is made to hook the ring at a free end of the other adjoining side frame.
  • each of the side frames has longitudinal bars and lateral bars combined to form a grill along a side of the beam, and each of cross points of the longitudinal bars and the lateral bars is welded, and the lateral bars of two of the side frames extend perpendicular to a longitudinal direction of the beam, and ends of the lateral bars are bent obliquely inward so as to hook the longitudinal bars at ends of the adjoining side frame.
  • the said four side frames are hinged to two pairs, and the lateral bars of two opposing side frames are turnably coupled with the end longitudinal bars of the other two opposing side frames.
  • the two side frame pairs may be formed L shape by integrating their lateral bars.
  • all the four side frames are turnably coupled together, and only one of the side frames is made detachable.
  • the present invention consists in the novel and useful provision. Formation, construction, association and relative arrangement of parts, members and features, all as shown in the accompanying drawing, described generally, and more particularly pointed out in the claims.
  • An advantage of the present invention consists in particular in the fact that number of working steps can be decreased to a great extent as the side frames A, B1, B2, C1, C2, and C3 can be fabricated at factory and should be only linked together on site.
  • Another advantage of the present invention consists in that the side frames A, B1, B2, C1, C2, and C3 are more sturdy than the conventional ones bound on site as their lateral and longitudinal bars are welded at the cross points. This can reduce binding material.
  • a ferroconcrete constructing frame 12 surrounding a beam 11 forming a pillar or similar structural parts comprises four side frames independent from one another, each of which has a plurality of lateral bars a 2 to c3 7 and a plurality of longitudinal bars 1 crossing them at right angles. All the crossing points is fixed by welding. Appropriate four of the completed side frames A, B1, B2, C1, C2, and C3 are selected to form the ferroconcrete constructing frame 12.
  • Fig. 1a shows the side frame A lateral bars a 2 of which have a ring 8 formed on a plane perpendicular to the longitudinal bars 1 at each of ends thereof.
  • Fig. 1b shows the side frame B1 lateral bars b1 3 of which have a ring 8 formed on a plane perpendicular to the longitudinal bars 1 at one end thereof and a hook a 9 formed on the plane at the other end.

  • Fig. 1d shows the side frame C1 lateral bars c1 5 of which have a hook a 9 formed on a plane perpendicular to the longitudinal bars 1 at each of ends thereof.
  • Fig. 1e shows the side frame C2 lateral bars c2 6 of which have one hook 10 at each of ends thereof, which are bent reversely from each other on a plane parallel with the lateral bars c2 6.
  • Fig. 1f shows the side frame C3 lateral bars c3 7 of which have a hook a 9 formed on a plane perpendicular to the longitudinal bars 1 at one of ends thereof and a hook b 10 bent from the longitudinal bars 1 on a plane parallel with the lateral bars c3 7 at the other end.
  • Fig. 2a is an example of ferroconcrete constructing frame 12 of the present invention having three side frames A and one side frame B1 assembled together.
  • the ferroconcrete constructing frame 12 should be assembled in the way that first, the adjoining side frames A and B1 should be made to align at their rings 8 and have a stick bar 13 passed through every couple of the rings 8 to link them.
  • the end side frame A should have the stick bar 12 passed through each couple of the end rings 8 thereof.
  • the ferroconcrete constructing frame 12 developed as such should be wound around the beam 11 forming the pillar or similar structural parts.
  • the hooks a 9 of the side frame B1 should be made to hook the stick bar 13 passed through the rings 8 at a free (no coupling) end of the side frame A opposite to the side frame B1.
  • Fig. 2b is another example of ferroconcrete constructing frame 12 of the present invention having three side frames A and one side frame B2 assembled together.
  • the ferroconcrete constructing frame 12 should be assembled in the way that first, the adjoining side frames A and B2 should be made to align at their rings 8 with the stick bar 13 passed through each couple of the rings 8 to link them.
  • the ferroconcrete constructing frame 12 developed as such should be wound around the beam 11 forming the pillar or similar structural parts.
  • the hooks b 10 of the side frame B2 should be made to directly hook the rings 8 at a free (no coupling) end of the side frame A opposite to the side frame B1.
  • Fig. 2c is still another example of ferroconcrete constructing frame 12 of the present invention having three side frames A assembled together and one separate side frame C1.
  • the ferroconcrete constructing frame 12 should be assembled in the way that first, the adjoining side frames A should be made to align at their rings 8 with the stick bar 13 passed through each couple of the rings 8 to link them.
  • the semi-assembled ferroconcrete constructing frame of the three side frames should be wound around the beam 11 and have the stick bar 13 passed through each couple of the end rings 8. After this, the hooks a 9 of the last side frame C1 should be made to hook the respective stick bars 13 passed through the rings 8.
  • Fig. 2d is still another example of ferroconcrete constructing frame 12 of the present invention having three side frames A assembled together and one separate side frame C2.
  • the ferroconcrete constructing frame 12 should be assembled in the way that first, the adjoining side frames A should be made to align at their rings 8 with the stick bar 13 passed through each couple of the rings 8 to link them.
  • the semi-assembled ferroconcrete constructing frame of the three side frames should be wound around the beam 11.
  • the hooks b 10 of the side frame C2 should be made to directly hook the respective rings 8 of the semi-assembled ferroconcrete constructing frame.
  • Fig. 2e is still another example of ferroconcrete constructing frame 12 of the present invention having three side frames A assembled together and one separate side frame C2.
  • the ferroconcrete constructing frame 12 should be assembled in the way that first, the adjoining side frames A should be made to align at their rings 8 with the stick bar 13 passed through each couple of the rings 8 to link them.
  • the semi-assembled ferroconcrete constructing frame of the three side frames should be wound around the beam 11 and have the stick bar 13 passed through couples of the rings 8 on either of the free ends.
  • the hooks a 9 of the side frame C3 should be made to hook the stick bar 13 passed through the rings 8 on the one free end and be made to directly hook the rings 8 of the other free end.
  • Fig. 3 is a cross-sectioned view of an example of applications of the ferroconcrete constructing frame 12 to the beam 11 or the like.
  • Fig. 3a is an application in which the assembly shown in Fig. 2a is used.
  • a crane is used to lift the assembled side frames A linked with the side frame B1 to put on the beam 11 or the like.
  • Fig. 3b shows the completed ferroconcrete constructing frame 12 that the free end of the lowest side frame A is pulled up with the hook a 9 made to hook the stick bar 13 passed through the rings 8 thereof to thoroughly surround the beam 11.
  • the stick bar 13 is not passed through the rings 8 on the free end of the lowest side frame A as the side frame B2 is used. Instead, the hooks b 10 should be made to directly hook the rings 8 to complete the ferroconcrete constructing frame 12 that thoroughly surrounds the beam 11.
  • the side frames A, B1, B2, C1, C2, and C3 should not always be plane, but may be, for example, curved.
  • Fig. 4 is shown four side frames E, F, G, and H for surrounding a beam 21 forming a pillar or similar structural parts.
  • Each of the side frames has longitudinal bars e1, e2 and so forth and lateral bars f1, f2 and so forth combined to form a grill along a side of the beam 21.
  • Each of cross points 21 of the longitudinal bars and lateral bars is welded.
  • the side frames E and G have five longitudinal bars e1, e2 through en each.
  • An end fy of each of the lateral bars f1, f2 and so forth is bent obliquely inward to hook and be welded with the respective longitudinal bars e1 and e2 on the both ends.
  • Each of the side frames F and H has three longitudinal bars e1 and e2 and e3 and has no longitudinal bars on the both ends.
  • the lateral bars f1, f2 and so forth of the side frame F and G extend perpendicular to the longitudinal direction of the beam 21. Ends fx of the lateral bars are bent obliquely inward so as to hook the longitudinal bars e1 and en at ends of the adjoining side frame E and G.
  • the end fx is as long as four or more times diameter of the longitudinal bar e1 and extends, or is twisted, in the same oblique direction as the end fy mentioned above, or is twisted, not to interfere the ends fy of the side frames E and G as shown in Fig. 9. Since the end fx extends, or is twisted, obliquely inward, it will not obstruct spot points when it is welded on the longitudinal bars e1 and en.
  • each of the ends fy like the ends fx, extends, or is twisted, obliquely inward. It is made long enough to spirally entangle around the longitudinal bar e1 or en by an angle of 180 to 360 degrees, preferably 270 degrees. Distance between the adjoining lateral bars f1 of the side frames E and F combined together are made uniform. This allows the ends fy contact each other between the welded ends fx. The ends fy cannot move in axial directions of the longitudinal bars e1 and en. Note that the adjoining ends fy and fx are symmetrical.
  • the side frames E, F, G, and H should be put along the beam 21 to surround.
  • the ends fx of the lateral bars f1, f2 and so forth of the side frames F and G should be made to hook the end longitudinal bars e1 and en of the adjoining side frames A and C.
  • a form (not shown) should be placed outside the completed ferroconcrete constructing frame. Concrete should be poured in the form to erect concrete block 23 as indicated by a dot-dash-line in Fig. 4.
  • the ferroconcrete constructing frame may be placed outside an iron bar bundle, support, or similar structural parts instead of the beam.
  • Fig. 7 shows still another embodiment of the present invention.
  • the four side frames E, F, G, and, H mentioned above are hinged to two pairs of E and F and G and H.
  • the lateral bars f1, f2 and so forth of the two opposing side frames F and H are turnably coupled with the end longitudinal bars e1 of the other two opposing side frames E and F.
  • the side frame pairs E and F and G and H can be folded plain as they are hinged. They can be easily transported to site and assembled as they should be simply coupled together there.
  • the two side frame pairs E and F and G and H may be formed L shape by integrating their lateral bars f1, f2 and so forth. In this case, the pairs cannot be folded, but can be assembled further easily as they are formed L shape.
  • Fig. 8 shows still another embodiment of the present invention.
  • Three adjoining side frames E, F, and H of the above-mentioned four are formed U shape by integrating their lateral bars f1, f2 and so forth. Assembling the U-shaped frame and plain side frame can be made further more easily without the beam 21.
  • still another advantage of the present invention consists in particular in the fact that the side frames E, F, G, and H of the present invention can be assembled in the simple way that they should be placed around the beam or bar bundle and the ends fx of the lateral bars f1, f2 and so forth should be made to hook the end longitudinal bars. This makes on-site work simple and easy as it eliminates bar cutting and binding works.
  • Still another advantage of the present invention consists in particular in the fact that the side frames are stronger than the conventional ones bound on site. This can save binding material.
