Description

[Technical field]

[0001] The present invention relates to a frame body of a beam reinforcing bar assembly frame. [Background technology]

[0002] A building using reinforcing bars has a reinforced concrete column and a reinforced concrete beam that is installed horizontally to the column. The reinforced concrete beam is made of beam reinforcing bars and concrete. The beam reinforcing bars are formed of multiple straight beam bars and multiple frame-shaped stirrup bars that are tied to each beam bar with wire or the like. Reinforced concrete beams are manufactured by assembling the beam reinforcing bars with the beam bars and stirrup bars, forming a form to surround the assembled beam reinforcing bars, and pouring concrete into the form.

[0003] Stirrup bars are classified into one-piece type and split type. The one-piece type is integrally formed into a quadrilateral frame. The split type is formed into an overall quadrilateral shape with a roughly U-shaped main body with an open upper end and width stop bars arranged on the opening side of the main body. Beam reinforcing bars are incorporated inside the stirrup bars so that they extend straight. The beam reinforcing bars usually have an upper beam reinforcing bar group consisting of multiple beam reinforcing bars arranged in the upper part of the reinforced concrete beam, and a lower beam reinforcing bar group consisting of multiple beam reinforcing bars arranged in the lower part of the reinforced concrete beam.

[0004] Patent Document 1 discloses a beam reinforcement assembly stand having a stand body constituting a pair of stand assemblies, a stirrup support supporting stirrup bars, a first beam reinforcement support rod supporting the beam reinforcements constituting the upper beam reinforcement group, and a second beam reinforcement support rod supporting the beam reinforcements constituting the lower beam reinforcement group.

[0005] In this beam reinforcing bar assembly stand, the multiple beam bars constituting the upper beam reinforcing bar group are placed on the first beam reinforcing bar support bar, and the multiple beam bars constituting the lower beam reinforcing bar group are placed on the second beam reinforcing bar support bar, so that the stirrup bars and the beam reinforcing bars can be prepared to be tied together without interference between them.The stirrup bars are distributed so that their upper edges come into contact with the upper beam reinforcing bar group, and the lower beam reinforcing bar group is moved downward to come into contact with the lower edges of the stirrup bars, so that the stirrup bars and the beam reinforcing bars can be assembled safely in a short time to manufacture the beam reinforcing bar.

[0006] [Patent Document 1] Patent No. 5118897 Summary of the Invention [Problem to be solved by the invention]

[0007] The frame body of the above-mentioned beam reinforcement bar assembly frame is quite heavy, so that it requires two people to move it manually, and installation requires a lot of labor and cost.

[0008] An object of the present invention is to provide a frame body for a beam reinforcement assembly frame that can be easily installed. [Means for solving the problem]

[0009] The frame body of the beam reinforcing bar assembly frame according to the present invention is a beam reinforcing bar assembly frame for assembling beam reinforcing bars consisting of upper beam reinforcing bars formed of multiple beam reinforcing bars extending parallel to each other, lower beam reinforcing bars formed of multiple beam reinforcing bars extending parallel to each other and arranged parallel to the upper beam reinforcing bars, and multiple frame-shaped stirrup bars tied to each of the beam reinforcing bars. The frame body is equipped with a first beam reinforcing bar support rod supporting the upper beam reinforcing bars, a second beam reinforcing bar support rod supporting the lower beam reinforcing bars, and a stirrup support base supporting the stirrup reinforcing bars, which are detachably attached to the frame body, the frame body is composed of a support column and a leg portion provided at the lower end of the support column and in contact with the installation surface, the leg portion being composed of a first leg and a second leg perpendicular to the first leg, and the frame body is equipped with a wheel mechanism consisting of a cross member attached across the first leg and the second leg, and a plurality of wheels supported by the cross member and rotatable, This is a frame body of a beam reinforced concrete assembly frame, characterized in that when the frame body is inclined with respect to the installation surface, the multiple wheels are in contact with the installation surface and the legs are spaced apart from the installation surface.

[0010] In addition, in the frame body of the beam reinforcement bar assembly frame according to the present invention, the cross member is disposed at an angle of 45° to the first leg and the second leg.

[0011] Furthermore, in the frame body of the beam reinforcing bar assembly frame according to the present invention, the wheel mechanism is detachable from the first leg and the second leg. Effect of the Invention

[0012] According to the base body of the beam reinforcement assembly base of the present invention, when the base body is inclined relative to the installation surface, the multiple wheels come into contact with the installation surface and the legs are spaced away from the installation surface, so that the base body can be easily moved and installed by human power.

[0013] By positioning the bridge member supporting the multiple wheels at a 45° angle to the first and second legs, the multiple wheels come into stable contact with the installation surface when the platform body is inclined relative to the installation surface, allowing the platform body to be moved stably.

[0014] Because the wheel mechanism is detachable from the first leg and the second leg, the wheel mechanism can be removed from an installed base body and attached to an uninstalled base body, thereby reducing the number of wheel mechanisms in the entire beam reinforcing bar assembly base and reducing costs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is a perspective view showing a pair of frame assemblies constituting a beam reinforcing bar assembled frame according to one embodiment, Fig. 2 is an exploded perspective view showing a frame main body constituting a pair of frame assemblies, Figs. 3 to 7 are front views showing an assembly process of a beam reinforcing bar using a beam reinforcing bar assembled frame, Fig. 8 is an enlarged side view in the direction of the arrow 8-8 in Fig. 5, Fig. 9 is an enlarged side view in the direction of the arrow 9-9 in Fig. 6, Fig. 10 is an enlarged side view in the direction of the arrow 10-10 in Fig. 7, Fig. 13 is a front view of the frame main body, and Fig. 14 is a perspective view showing a state in which the frame main body is inclined with respect to an installation surface.

[0017] The beam reinforcing bar assembly stand is used to assemble the beam reinforcing bar 10, as shown in Figures 7 and 10. The beam reinforcing bar 10 has an upper beam reinforcing bar group 11a composed of multiple beam reinforcing bars 11 extending straight and parallel to each other, and a lower beam reinforcing bar group 12a composed of multiple beam reinforcing bars 12 extending parallel to each other and parallel to the upper beam reinforcing bar group 11a, and multiple quadrilateral frame-shaped stirrup reinforcing bars 13 are arranged at predetermined intervals to surround the upper beam reinforcing bar group 11a and the lower beam reinforcing bar group 12a. The stirrup reinforcing bars 13 and the respective beam reinforcing bars 11, 12 are tied together by wires (not shown) to complete the assembly of the beam reinforcing bar 10.

[0018] As shown in Fig. 1, a pair of rack assemblies 20 is composed of a first rack body 21 and a second rack body 22, and the rack bodies 21, 22 have the same structure. Each rack body 21, 22 has a support 23 made of a hollow square pipe with a square cross section, and a leg 24 is attached to the lower end of the support 23, so that the support 23 is installed vertically on a base surface (installation surface) at the leg 24. An engagement hole 23a is formed in the upper end of the support 23, and when the support 23 is suspended by an elevator (not shown), a hook of the elevator engages with the engagement hole 23a.

[0019] A cradle support member 25 made of a square pipe is detachably attached to the side of the upper end of the support column 23 in parallel with the support column 23. As shown in FIG. 2, a U-shaped bracket 26 that covers three sides of the support column 23 is fixed to the lower end of the support column support member 25, and a U-shaped hook 27 that opens upward is fixed to the upper end. Through holes 28 are formed on two opposing sides of the bracket 26, and a plurality of through holes 29 are formed at predetermined intervals in the longitudinal direction of the support column 23. The cradle support member 25 is detachably attached to the support column 23 by passing a bolt 30 through the through hole 28 through one of the through holes 29 to fix the bracket 26 to the support column 23. The height of the upper end of the cradle support member 25 can be changed in multiple steps by changing the position of the through hole 29 through which the bolt 30 passes.

[0020] As shown in Fig. 1, a stirrup support 31 is removably attached to the upper end of the support base support member 25. The stirrup support 31 is composed of a support bar 32 made of a square pipe supported at both ends by hooks 27 of the support base support member 25, and a number of support bars 34 protruding from both sides in the width direction of the support bar 32 and fixed by clamps 33. As shown in Fig. 4, the stirrup support 31 supports the stirrup bars 13 vertically at the inner part of their upper side.

[0021] As shown in Fig. 1, an engagement groove 35 that opens upward is formed at the upper end of the support column 23, and a first beam reinforcement support bar 36 made of a round bar is removably attached to this engagement groove 35. A pair of frame assemblies 20 is formed by arranging the first frame body 21 and the second frame body 22 in a pair as shown in Fig. 1. On the first beam reinforcement support bar 36 attached to the frame assembly 20, each beam reinforcement 11 that constitutes the upper beam reinforcement group 11a is supported horizontally in parallel with each other as shown in Fig. 5.

[0022] A U-shaped bracket 37 is attached to the support 23 so as to cover three sides of the support 23, and a hook 38 is attached to the bracket 37. As shown in FIG. 2, through holes 39 are formed on two opposing sides of the bracket 37, and an eye bolt 40 is inserted through the through hole 39 to be attached. Therefore, when the bracket 37 is attached to the support 23 and the eye bolt 40 is fastened, the bracket 37 is fastened to the support 23 by the fastening force applied to the bracket 37 by the eye bolt 40. When the eye bolt 40 is loosened, the position of the bracket 37 can be adjusted in the vertical direction. In this way, by fastening the bracket 37 with the eye bolt 40, the eye bolt 40 can be fastened and unfastened using a rod-shaped member without using a spanner at the beam reinforcing bar assembly site. In addition, with regard to the receiving platform support member 25, the length of the two opposing sides of the bracket 26 may be increased so that the receiving platform support member 25 is attached to the support column 23 by the fastening force of bolts.In this case, the receiving platform support member 25 can be adjusted to any height position rather than in stages.

[0023] A second beam reinforcement support bar 41 made of a round bar is removably attached to the hook 38 attached to the bracket 37 as shown in Fig. 1. Each of the beam reinforcement bars 12 constituting the lower beam reinforcement group 12a is supported horizontally and parallel to each other on the second beam reinforcement support bar 41 attached to the pair of frame assemblies 20 as shown in Fig. 5. Therefore, when the bracket 37 is shifted downward while supporting each of the beam reinforcement bars 12 constituting the lower beam reinforcement group 12a, the beam reinforcement bars 12 are shifted downward. In other words, after the stirrup bars 13 supported by the stirrup support base 31 are arranged at a predetermined interval on the upper beam bar group 11a as shown in Figures 6 and 9, when each beam bar 12 constituting the lower beam bar group 12a is supported by the second beam bar support bar 41, as shown in Figures 7 and 10, when the second beam bar support bar 41 is shifted downward by the bracket 37 to release the support of the beam bars 12, each beam bar 12 constituting the lower beam bar group 12a will come into contact with the inside of the lower piece of the stirrup bar 13. To release the support of the beam bars 12 by the second beam bar support bar 41, the bracket 37 may be shifted downward, or the second beam bar support bar 41 may be removed.

[0024] In this way, the beam bars 11 of the upper beam bar group 11a come into contact with the inside of the upper side of the stirrup bar 13, and the beam bars 12 of the lower beam bar group 12a come into contact with the inside of the lower piece of the stirrup bar 13. In this state, the stirrup bar 13 and each of the beam bars 11 and 12 are tied together with wire to complete the assembly of the beam reinforcing bars.

[0025] 1 and 2, leg 24 fixed to the lower end of support 23 has two fixed legs 42 fixed to the underside of support 23 and protruding on both sides in a direction perpendicular to support 23. Fixed legs 42 and detachable leg 47 are made of metal and have a channel-shaped cross section.

[0026] As shown in Fig. 2, the fixed legs 42 are connected to each other by connecting plates 43 via gaps 44, and the fixed legs 42 are attached to the support 23 by screwing an attachment member 45 fixed to the support 23 to the fixed legs 42 with bolts 46. A detachable leg 47 is attached to the gap 44 in a direction perpendicular to the fixed leg 42. As shown in Fig. 2, the detachable leg 47 is adapted to be detachably attached to the support 23 by a bolt 49 which passes through a through hole 48 formed in the center of the detachable leg 47 in the longitudinal direction and is screwed into a nut (not shown) provided at the lower end of the support 23.

[0027] 2, the detachable legs 47 can be folded so as to overlap the fixed legs 42. When the detachable legs 47 are fastened to the fixed legs 42 with the bolts 49 in the folded state, the occupied area can be reduced when the gantry bodies 21, 22 are transported or stored, that is, when not in use. Moreover, the cradle support member 25 and the bracket 37 are detachable from the support columns 23, so that by removing these from the support columns 23, the occupied area of ​​the gantry bodies 21, 22 during transportation or storage can be reduced. Note that an eye bolt may be used instead of the bolt 49.

[0028] As shown in FIG. 1, a wheel mechanism 130 including a connecting member 100, a first wheel 110, and a second wheel 120 is attached to a fixed leg 42, which is an example of a first leg, and a detachable leg 47, which is an example of a second leg.

[0029] The cross-connecting member 100 is made of metal and has an angle-shaped cross section. The cross-connecting member 100 is attached across the fixed leg 42 and the detachable leg 47. As shown in Fig. 2, an insertion hole 100a is formed in the cross-connecting member 100 at the location where it is attached to the fixed leg 42, and an insertion hole 100b is formed in the location where it is attached to the detachable leg 47. Bolt holes 42a, 42b are formed in the fixed leg 42 at the location where the cross-connecting member 100 is attached, and bolt holes 47a, 47b are formed in the detachable leg 47 at the location where the cross-connecting member 100 is attached.

[0030] The connecting member 100 is attached to the fixed leg 42 and the detachable leg 47 by inserting a bolt 101 through the insertion hole 100a and screwing it into the bolt hole 42a, and by inserting a bolt 102 through the insertion hole 100b and screwing it into the bolt hole 47a. Although not shown, the connecting member 100 may be attached to the bolt hole 42a and the bolt hole 47b, the bolt hole 47b and the bolt hole 42b, or the bolt hole 42b and the bolt hole 47a. Conversely, the connecting member 100 can be removed from the fixed leg 42 and the detachable leg 47 by removing the bolts 101 and 102.

[0031] The connecting member 100 is disposed at an angle of 45° with respect to the fixed leg 42 and the detachable leg 47. That is, the angle α between the connecting member 100 and the fixed leg 42 is 45°, and the angle β between the connecting member 100 and the detachable leg 47 is also 45°.

[0032] A plurality of wheels are rotatably supported on the connecting member 100. In this embodiment, the plurality of wheels include two wheels, a first wheel 110 and a second wheel 120. The first wheel 110 is rotatable about a support shaft provided on a support frame 111. The support frame 111 is attached to the connecting member 100. Similarly, the second wheel 120 is rotatable about a support shaft provided on a support frame 121. The support frame 121 is attached to the connecting member 100.

[0033] 13, when the first gantry body 21 is installed on an installation surface G, that is, when the first gantry body 21 stands upright on the installation surface G, the first wheel 110 and the second wheel 120 are spaced apart from the installation surface G by a distance D. In the state shown in FIG. 13, the first gantry body 21, which is a heavy object, cannot be easily moved by human force.

[0034] From this state, when the first gantry body 21 is tilted toward the front side with the end 42c of the fixed leg 42 and the end 47c of the detachable leg 47 as a fulcrum, the first gantry body 21 is tilted with respect to the installation surface G, and the interval D is narrowed, and the first wheel 110 and the second wheel 120 come into contact with the installation surface G, while the fixed leg 42 and the detachable leg 47 are separated from the installation surface G, as shown in FIG. 14. In this state shown in FIG. 14, the first gantry body 21 can be easily moved by human power by the rotation of the first wheel 110 and the second wheel 120. The second gantry body 22 is the same as the gantry body 21.

[0035] 2, an extension column 51 is removably attached to the upper end of the column 23. The extension column 51 has a protruding portion 51a made of a square pipe of the same size as the column 23, and a fitting portion 51b attached to the lower end of the protruding portion 51a and fitted inside the column 23, and a plurality of through holes 52 are formed in the fitting portion 51b. Therefore, by passing a bolt (not shown) through one of the through holes 29 of the column 23 and one of the through holes 52, the extension column 51 can be attached so as to protrude above the column 23, and the protruding length can be set in a plurality of stages.

[0036] An engagement groove 35 is formed at the upper end of the extension support 51, similar to the upper end of the support 23, and the first beam reinforcement support bar 36 can be placed in the engagement groove 35. Therefore, by attaching the extension support 51 to the support 23, the height of the first beam reinforcement support bar 36 can be set in multiple stages. Although the support 23 and the extension support 51 are formed of square pipes, they may also be round pipes. Furthermore, although the first beam reinforcement support bar 36 and the second beam reinforcement support bar 41 are formed of round pipes, they may also be square pipes.

[0037] Next, the process of assembling a beam reinforcing bar using the beam reinforcing bar assembly stand will be described with reference to Figures 3 to 10. Note that in Figures 3 to 10, the wheel mechanism 130 is omitted.

[0038] First, the frame bodies 21 and 22 are moved to a desired location as described in Fig. 13. Here, the connecting member 110 supporting the multiple wheels (first wheel 110, second wheel 120) is arranged at an angle of 45° with respect to the fixed leg 42 and the detachable leg 47, so that the multiple wheels stably contact the installation surface G with the frame bodies 21 and 22 inclined with respect to the installation surface G, and therefore the frame bodies 21 and 22 can be moved stably. In addition, the wheel mechanism 130 can be removed from the moved frame bodies 21 and 22, and the removed wheel mechanism 130 can be attached to another frame body 21 and 22, thereby reducing the number of wheel mechanisms 130 in the entire beam reinforcing bar assembly frame, and reducing costs.

[0039] 1, each frame assembly 20 is formed by arranging two frame bodies 21, 22 at a distance from each other. A first beam bar support bar 36 is attached to each frame assembly 20 by engaging both ends with the engagement grooves 35 of the two frame bodies 21, 22, and a second beam bar support bar 41 is attached to each frame assembly 20 by engaging both ends with the hooks 38.

[0040] In this way, a plurality of pairs of frame assemblies 20 each formed by two frame bodies 21, 22 are arranged in a straight line at a predetermined interval corresponding to the length of the beam bars 11, 12 forming the beam reinforcing bar 10, as shown in Fig. 3. In the case shown in Fig. 3, five pairs of frame assemblies 20 are arranged on the base corresponding to the length of the beam bars 11, 12, and stirrup supports 31 are attached to the support support members 25 of a total of two pairs of frame assemblies 20, with both ends engaged with hooks 27, between the pair of frame assemblies 20. The number of frame assemblies 20 used to assemble the beam reinforcing bar 10 can be any number according to the length of the beam bars 11, 12.

[0041] With a predetermined number of frame assemblies 20 in place, a number of frame-shaped, i.e. loop-shaped stirrup bars 13 are hung from the support rods 34 of the stirrup support base 31 as shown in Fig. 4. This causes the stirrup bars 13 to be supported vertically by the stirrup support base 31 at the inner part of their upper sides. However, it is also possible to attach the stirrup support base 31 to all frame assemblies 20 and hang the stirrup bars 13 from each stirrup support base 31.

[0042] In this way, with the stirrup reinforcing bars 13 supported by the support bar 32 of the stirrup support base 31 at the inside of its upper side, a number of beam reinforcing bars 11 are placed on the first beam reinforcing bar 36 as shown in Figs. 5 and 8. As a result, all beam reinforcing bars 11 constituting the upper beam reinforcing bar group 11a are supported horizontally on the first beam reinforcing bar 36, penetrating the inside of the stirrup reinforcing bars 13 without interfering with them. Similarly, a number of beam reinforcing bars 12 are placed on the second beam reinforcing bar 41. As a result, all beam reinforcing bars 12 constituting the lower beam reinforcing bar group 12a are supported horizontally on the second beam reinforcing bar 41, penetrating the inside of the stirrup reinforcing bars 13 without interfering with them, and the lower beam reinforcing bar group 12a and the upper beam reinforcing bar group 11a are parallel to each other as shown in Fig. 8.

[0043] In this state, as shown in Figures 6 and 9, the stirrup bars 13 are removed from the stirrup support 31 and placed at a specified interval in the upper beam bar group 11a. This removal and placement operation can be easily performed without the stirrup bars 13 interfering with the beam bars 11 and 12, and the beam bars 11 constituting the upper beam bar group 11a come into contact with the upper side of the stirrup bars 13 as shown in Figures 6 and 9.

[0044] Next, the eyebolts 40 fastening the brackets 37 of each frame assembly 20 are loosened, and the brackets 37 are shifted downward to release the support of the beam bars 12 by the second beam bar support bar 41. As a result, the second beam bar support bar 41 is shifted downward, and the beam bars 12 constituting the lower beam bar group 12a come into contact with the inside of the lower side of the stirrup bars 13. However, the support of the beam bars 12 may be released by removing the second beam bar support bar 41 without shifting the brackets 37 downward. Figures 7 and 10 show the state in which the beam bars 12 of the lower beam bar group 12a come into contact with the stirrup bars 13 in this way.

[0045] With the beam bars 11 of the upper beam bar group 11a and the beam bars 12 of the lower beam bar group 12a in contact with the stirrup bars 13, the stirrup bars 13 and the beam bars 11, 12 are tied together with a wire (not shown), completing the assembly of the beam reinforcing bars 10. After the assembly is completed, the beam reinforcing bars 10 are lifted slightly upward by a crane (not shown) to remove the frame assembly 20, and then transported by the crane into a formwork and embedded in the concrete, completing the manufacture of the concrete beam. By attaching (or leaving attached) the wheel mechanism 130 to the frame bodies 21, 22, the frame bodies 21, 22 can be easily removed by human power.

[0046] In this way, in a state where a plurality of stirrup bars 13 are gathered and hung on the stirrup support 31, a plurality of beam bars 11 are arranged on the first beam bar support bar 36 so as to enter inside the stirrup bars 13, and a plurality of beam bars 12 are arranged on the second beam bar support bar 41, so that the stirrup bars 13 and the beam bars 11, 12 can be easily set without interfering with each other. In this state, the stirrup bars 13 are first distributed so that the upper beam bar group 11a contacts the inside of the upper side, and then the support of the lower beam bar group 12a by the second beam bar support bar 41 is released, so that the lower beam bar group 12a can be arranged inside the lower side of the stirrup bars 13.

[0047] 11 and 12 are side views showing a beam-reinforced concrete assembly frame according to another embodiment of the present invention, and in these figures, the same reference numerals are used to designate members common to the beam-reinforced concrete assembly frame described above.

[0048] Fig. 11 shows the assembled state of a type of beam reinforcing bar 10 in which large stirrup bars 13a with a long width dimension and small stirrup bars 13b with a shorter width dimension are mixed and attached to beam bars 11, 12. In this way, this beam reinforcing bar assembly stand can be used even when assembling a beam reinforcing bar 10 using multiple stirrup bars 13a, 13b that are integral and have different sizes.

[0049] Fig. 12 shows the assembled state of the beam reinforcing bar 10 using the split type stirrup bar 13c. The stirrup bar 13c is formed into a quadrilateral shape by the main body 14, which is approximately U-shaped and has an open upper end, and the width stop bar 15 arranged on the opening side of the main body 14. The opening side of the main body 14 of the stirrup bar 13c has a hook part 16, and the main body 14 is hung from the receiving bar 34 of the stirrup receiving base 31 at the hook part 16. After the main body 14 is hooked on the beam bar 11 located outside the upper beam bar group 11a, the width stop bar 15 may be attached to the upper beam bar group 11a. However, for the split type stirrup bar 13c, the main body 14 may be attached to the beam bar 11 while the beam bar 11 is supported by the first beam bar support bar 36 without using the stirrup receiving base 31.

[0050] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.

[0051] For example, the illustrated beam reinforcing bar 10 has upper beam reinforcing bar group 11a and lower beam reinforcing bar group 12a incorporated in stirrup bar 13, but in addition to these two rows of beam reinforcing bar groups, one or more rows of intermediate beam reinforcing bar groups may be provided. In that case, the beam reinforcing bar in the intermediate beam reinforcing bar group is connected to the upper beam reinforcing bar by an S-shaped hook metal fitting.
