Description

The present invention relates to a reinforcing bar support member and a reinforcing bar support frame used for installing a reinforcing bar for reinforced concrete, and more specifically, for a reinforcing bar installation that enables an inexperienced person to perform the installation of a reinforcing bar where a vertical reinforcing bar and a horizontal reinforcing bar cross each other accurately and efficiently . The present invention relates to a reinforcing bar support frame and a composite reinforcing bar support frame obtained by combining the support frame .

Reinforcement installation for reinforced concrete is still in place by placing the pillow material facing in the vertical direction and the pillow material corresponding to the horizontal direction in accordance with the shape of the product concrete so that there is a difference in height over the diameter of the rebar. Place a mark on the pillow to mark the spacing of the reinforcing bars, or affix gauge paper with lines printed at the spacing of the reinforcing bars, and match the above-mentioned chalk marks or printed lines. For example, place vertical rebars side by side on the pillow material, and then place the horizontal rebars side by side with the choke lines or printed lines on the support member of the higher rebar, as described above. Many methods are used to install the reinforcing bars by binding the crossing points with binding wires.

However, in the above method, since the rebar spacing is set according to the mark of the chalk and the printed line after calculating the interval between the reinforcing bars by marking with chalk or pasting the printing paper, it takes time to use the work. In addition, if you touch the reinforcing bar accidentally after placing it, the position will change and correction will be required.In addition, if you place the reinforcing bar on the support member, the position of the reinforcing bar will shift when placing concrete. In order to prevent this, a knot that binds the intersection of vertical and horizontal bars with a tie wire is required. However, this ligature requires skill and cannot be sure even for beginners. For this reason, at present when there is a lot of reinforced concrete work, there is a shortage of rebar assembly technicians and it is not possible to respond immediately to the request. There has been a strong demand for the development of technology that can solve this problem.

The present invention has been made in accordance with this situation, and it is possible for a beginner to reliably and efficiently install a reinforcing bar that does not require binding in a state where the vertical reinforcing bar and the horizontal reinforcing bar are crossed in a non-binding manner. and as its object to provide a reinforcing bar supporting frame body for mounting.

In order to solve the above-mentioned problems, the reinforcing bar support frame for reinforcing bar installation for reinforced concrete according to the present invention employs the following configuration.

The invention according to claim 1 is a support for reinforcing bars in which a required number of reinforcing bar through-holes are arranged in a thin plate supporting member arranged in the vertical direction and in the horizontal direction in accordance with the spacing of the reinforcing bars, and the reinforcing bars are supported through these through-holes. The support members in the vertical direction and the horizontal direction are made of the same thin plate material, and are joined to each other at the ends in the length direction to form a flat frame, and the through holes of the reinforcing bars are The vertical and horizontal support members are provided so as to be biased to one side with respect to the center in the width direction, and the vertical and horizontal support members are respectively arranged so that the through holes of the reinforcing bars are biased to the opposite side. At the same time, the reinforcing bars in the vertical direction and the horizontal direction are supported by passing through the reinforcing bars in the horizontal direction and the vertical direction through the through holes of the reinforcing bars, respectively .

According to a second aspect of the present invention, in the first aspect of the present invention , the reinforcing member is formed with reinforcing edges on both sides in the width direction thereof, and a joining piece is continuously provided at one end of each of the reinforcing edges. An insertion groove in which the joining piece can be engaged is formed .

According to a third aspect of the present invention, the plurality of longitudinal support members according to the first or second aspect are joined at the side edges in the width direction so as to cross each other at a predetermined angle, and the crossing angle is set at the joint portion. the combined connecting features rebar was placed in supported through holes of the auxiliary rebar provided rebar support member adjacent joined it.

In the invention according to claim 4, the plurality of longitudinal support members according to claim 1 or 2 are joined at the side edges in the width direction so as to form a cylindrical shape, and the joining angle is adjusted to each joining portion. that the joining rebar shape, was placed in supported through holes of the auxiliary rebar provided rebar support member adjacent are joined.

According to the first aspect of the present invention, when a plurality of reinforcing bar support members are joined at the end portions in the length direction, a flat reinforcing bar support frame is formed, and the through holes of the reinforcing bars are formed in the vertical direction and the horizontal direction of the thin plate. The support members in the vertical direction and the horizontal direction are provided so as to be biased to one side from the center of the width direction of the support member in the direction. The support frame can be formed by simply changing the length of the same support member, and can be formed with a single mold, thereby reducing costs. Moreover, of the installed rebar as vertical reinforcing bars and horizontal reinforcing bars intersect installation is, in the vertical direction and the horizontal direction reinforcing bar insertion hole of the support member, to passing to intersect the horizontal and vertical reinforcing bars respectively been done in quite a simple operation of only, moreover, installation was rebar, were example, because no external force is the need for repair and found to be stable without causing a positional shift also act, professional skills skilled even for beginners Reinforcement installation similar to the bundling-type rebar installation by can be done, and can be processed at any time if the need for rebar installation arises, so the delay of construction caused by waiting for the installation of the rebar by a skilled technician Can be solved completely. Further, the support member is Ri der just plug the rebar through holes of the plate surface, it is not necessary to bind the reinforcing bars, working efficiency is rather very high, half of the binding equation rebar installation by even skilled professional skills novice There is also an effect that installation can be performed in the following time. Also, when this support frame body is mass-produced, the work of joining the reinforcing bar support members to form the support frame body is carried out at the factory, and the formed support frame body is carried to the site to install the reinforcing bars. It is possible to further improve the efficiency.

According to the second aspect of the present invention, since reinforcing bars are formed on both sides in the width direction of the support member for the reinforcing bar, the thickness of the thin plate material is reduced as much as possible to save material and facilitate processing. In addition, it is possible to stabilize even if the reinforcing bar supporting members are used side by side without joining them by widening the width of the reinforcing edge. In addition, a joining piece is continuously provided at one end of both reinforcing edges, and an insertion groove is formed at the other end so that the joining piece can be engaged. Therefore, it is desired to join a thin plate material having a unit length. Since a reinforcing bar support member having a length can be obtained, it is not necessary to manufacture a large number of support members for each length, which is economical.

According to the invention of claim 3 , a plurality of reinforcing bar support frames are joined at a predetermined angle, and a joining rebar that matches the crossing angle is supported by the through hole at the joint, and installed. The reinforcing bar support frame for the wall and the wall are integrated, and the joint is formed with a composite reinforcing bar support frame in which the reinforcing bars for bonding straddling both the support frames are arranged. If the reinforcing bar is inserted into the through hole opposite to the horizontal direction and the horizontal reinforcing bar crosses and stabilizes, the installation of the reinforcing bar will be performed by a skilled technician. It can be done in less than half the time of installation by bundling. Also, when this composite support frame is mass-produced, the work of joining the reinforcing bar support members to form the support frame is performed at the factory, and the formed support frame is carried to the site to reinforce the reinforcing bars. Further efficiency can be achieved by performing installation.

According to the invention of claim 4 , a plurality of reinforcing bar support frames are joined so as to form a cylindrical shape at the side edges in the width direction, and the joining rebars suitable for the crossing angle are passed through the joints in the through holes. For example, a hollow cylindrical reinforcing bar support frame that is hollow for pillars, beams, girders, and other structural materials is integrally formed. A cylindrical reinforcing bar support frame is formed in which reinforcing bars for joining straddling the support frame are arranged, and the reinforcing bars are placed in the through holes facing each other in the vertical direction and the through holes facing each side in each support frame. Once inserted, in this case as well, the installation of the reinforcing bars, which are stable by crossing the longitudinal bars and the horizontal bars, can be done in less than half the time of installation by the binding of skilled technicians by the hands of beginners. Also, when this same type of cylindrical composite support frame is produced in large quantities, work to form a support frame by joining reinforcing bar support members is carried out at the factory, and the formed support frame is carried to the site. In addition, the efficiency can be further improved by installing the reinforcing bars.

  Embodiments of a reinforcing bar support member for reinforcing bar installation according to the present invention will be described below with reference to the drawings.

1 to 3 show the reinforcing bar supporting members for rebars installation. In this reinforcing bar support member A, as shown in FIG. 1, a required number of through holes 3 of the reinforcing bars 2 are arranged in the thin plate material 1 in accordance with the arrangement interval, and the reinforcing bars 2 are inserted into the through holes 3 as shown in FIG. 2. Since the reinforcing bar 2 is surrounded by the peripheral wall of the hole 3 and cannot move in any direction, the reinforcing bar 2 can be instantaneously supported without being displaced at a set interval. Therefore, when the plate-shaped reinforced concrete product 4 as shown by the chain line in FIG. 3 is molded, four pieces of the reinforcing bar support members A are arranged in abutment with the ends in the length direction according to the outer shape of the product 4, When the ends of the longitudinal reinforcing bars 2 were inserted into the through holes 3 of the reinforcing bars arranged in the longitudinal direction of the reinforcing bar support member A, the spacing of the reinforcing bars 2 was determined and supported by the through holes 3. Since the vertical reinforcing bars 2 can be arranged, next, when the end portions of the horizontal reinforcing bars 2 are respectively inserted into the through holes 3 arranged in the reinforcing bar supporting frame A facing in the lateral direction, the intervals between the reinforcing bars 2 are passed through the through holes 3. The arrangement of the horizontal reinforcing bars 2 determined and supported is performed, and the installation of the reinforcing bars combined so that the vertical reinforcing bars 2 and the horizontal reinforcing bars 2 cross each other is completed.

However, as described above, in order to combine the vertical reinforcing bar 2 and the horizontal reinforcing bar 2 so as to cross each other, the through hole 3 formed in the reinforcing bar supporting member A used in the vertical direction so that the vertical reinforcing bar 2 and the horizontal reinforcing bar 2 do not collide with each other. It is necessary to make a difference in height between the through holes 3 opened in the reinforcing bar support member A used in the lateral direction. For this reason, the reinforcing bar support member A used in the vertical direction and the reinforcing bar support member A used in the horizontal direction may be manufactured in two types having different through hole 3 heights. However, in this case, since two types of production molds are required, there is an increase in the cost of the reinforcing bar support member A due to the mold allowance. Therefore, if the position of the through hole 3 opened in the reinforcing bar support member A is biased upward, for example, above the center line SS in the width direction of the reinforcing bar support member A as shown in FIGS. If the upper and lower sides of the member A are reversed , the through hole 3 moves below the center line SS as shown in FIG. 3, so that the reinforcing bar support portion A for the vertical direction and the reinforcing bar support member for the horizontal direction are the same. An object can be used, and the cost can be reduced by manufacturing the reinforcing bar support member A in a single mold.

  Further, the thin plate 1 is provided with auxiliary reinforcing bar through holes 3 ′ in the intervals of the reinforcing bar through holes 3 arranged in line with the bar arrangement intervals as described above. When forming a composite support frame or a cylindrical support frame by joining a plurality of rebar support frames formed as described later with the auxiliary through-holes 3 ', they are arranged at the joining corners of adjacent rebar support frames. Thus, the joining rebar 2 for mutual joining is inserted and used to be arranged at the joining corner.

Figure 4 shows the reinforcing bar supporting member for reinforcing bar installation, just Opening and number of through-holes 3 of the rebar 2 being the column set is different in accordance with the plate surface 1 to Haisuji interval, Since other structures and operations are the same, only the portions of the through holes 3 that differ from each other will be described below, and descriptions of the same portions will be omitted.

The rebars support member A of this, the position of the through-hole 3 through which reinforcing bars 2 when vertically disposed relative the position of the through-holes 3 through which reinforcing bars 2 in the case of providing relative to the horizontal direction, FIG. As shown in FIG. 4, they are lined up so as to be positioned above and below the center line SS in the width direction. And when providing the reinforcing bar support member A relative to the vertical direction, for example, the end of the reinforcing bar 2 is inserted into the through hole 3 located below the center line SS as shown in FIG. When the interval between the vertical reinforcing bars 2 is determined and supported by the through holes 3 and they are provided in the horizontal direction, the horizontal reinforcing bars are inserted into the through holes 3 located above the center line SS as shown in FIG. If the end of 2 is inserted and the interval between the horizontal reinforcing bars 2 is determined and supported by the through holes 3, the reinforcing bars 2 combined so that the vertical reinforcing bars 2 and the horizontal reinforcing bars 2 cross each other are installed.

  Further, the through holes 3 and 3 of the rebar 2 are arranged in a row as shown in FIGS. 4 and 5 so as to be parallel to the through holes 3 and 3 outside the through holes 3 and 3 of the two rebars 2. Although not shown in the drawings, when the reinforcing bar supporting member A is wide, it is arranged in two or more rows, and further, the spacing between the through holes 3 is also set in each case, or a plurality of auxiliary reinforcing bars are passed through. When forming a composite support frame or a cylindrical support frame by joining a plurality of reinforcing bar support frames in which holes 3 'are provided and these auxiliary through holes 3' are formed as described later, each reinforcing bar support frame It arrange | positions in this joining corner | angular part, and it utilizes for inserting and inserting the reinforcing bar 2 for joining mutually and hold | maintaining to a joining corner | angular part.

  The reinforcing bar support member A is formed using steel or synthetic resin. However, since it is preferable that the reinforcing bar support member A does not exist for the concrete product 4, a thin material is used as much as possible. A U-shape shown in FIG. 6 (a) with reinforcing edges 5 formed on the side or both sides, a Z-shape shown in FIG. 6 (b), an L-shape shown in FIG. 6 (c), and an inverted T-shape shown in FIG. 6 (d). The rectangular tube shown in FIG. 6E is formed. And when arranging the reinforcing bar support member A side by side according to the external shape of the concrete product, the width of the reinforcing edge 5 is widened as shown in FIGS. 6 (a), (b), (c), (d) and (e), and the reinforcing bar The support member A can maintain a stable standing posture. However, as will be described later, when a plurality of reinforcing bar support members A are joined at end portions in the length direction to form a reinforcing bar support frame, the reinforcing edge 5 is used. It should be narrow enough to perform only the reinforcing function.

  In addition, as for the said reinforcing bar support member A, the magnitude | size of a concrete product is various, and it is uneconomical to form the thing of the length corresponding to this. Therefore, the reinforcing bar support member A is set to a standard length in consideration of various conditions, and the reinforcing bar support member A having this length is formed to have the reinforcing edges 5 and 5 on both sides in the width direction. As shown in FIG. 7A, joint pieces 6 and 6 are continuously provided at one end of the reinforcing edges 5 and 5, and insertion grooves 7 and 7 into which the joint pieces 5 and 5 are inserted are provided at the other end. When the long reinforcing bar support member A is required, the joining pieces 6 and 6 connected to the reinforcing edges 5 and 5 of the one support member A as shown in FIG. When inserting into the insertion grooves 7 and 7 formed in the reinforcing bar support member A, the two reinforcing bar support members A and A are joined. The reinforcing bar supporting member A having a length to be formed can be formed. However, if the desired dimensions cannot be obtained by the above-mentioned joining alone, the reinforcing bar support member A is joined so as to be longer than the desired length, and the surplus portion is cut off to obtain the desired length of the reinforcing bar support member A. To be able to.

  Further, when the reinforcing bar support member A has a joining structure as described above, when the vertical reinforcing bar 2 is added as shown in FIG. 8, a relay reinforcing bar support member A is provided in this portion, and this supporting member is provided. If the end of the reinforcing bar to be added to the lower through hole 3 of A and the end of the reinforcing bar added to the intermediate through hole 3 are inserted and supported so as to overlap as shown in FIG. Easy to do.

Figure 9 shows a reinforcing bar supporting frame body according to claim 1, this embodiment, when fabricating a plate-like reinforced concrete products 4 of the same type in large quantities, rebar support member in accordance with the outer shape as described above If the reinforcing bars are installed side by side, the work efficiency is poor. Therefore, the required number of reinforcing bar support members A are joined together by welding with the end portions in the length direction as shown in FIG. As shown in FIG. 9, an L-shaped metal fitting 8 is attached to the outside of the butt portion and joined by spot welding to form a reinforcing bar support frame B that matches the outer shape of the plate-like concrete product 4 shown by a chain line in FIG. 9. Then, if the end portions of the reinforcing bars 2 in the vertical direction are inserted into the through holes 3 of the reinforcing bars arranged in the reinforcing bar support members A facing in the vertical direction of the reinforcing bar support frame B, the interval between the through holes 3 is determined. Since the vertical reinforcing bars 2 are stably arranged with support, if the end portions of the horizontal reinforcing bars 2 are respectively inserted into the reinforcing bar through holes 3 opened in the reinforcing bar supporting member A facing in the lateral direction, the through holes are provided. The horizontal rebar 2 is stably arranged by determining and spacing by 3 and the installation of the rebar in which the vertical rebar 2 and the horizontal rebar 2 are crossed and combined is performed more efficiently by using the support frame B. .

FIG. 10 shows an embodiment of a composite reinforcing bar support frame according to claim 3, and the composite reinforcing bar support frame C shown in this embodiment has a width of a plurality of B 1 and B 2 of the reinforcing bar support frame B. Are joined together at the side edges in the direction to form an L shape as shown in FIG. 10 or a U shape or the like (not shown in the drawing). The other reinforcing bar support frame B2 is used as a composite reinforcing bar support frame C for the wall, and the joining corners of both reinforcing bar support frames B1 and B2 are adapted to the joining angle. The reinforcing bar 2 'for joining in a shape is arranged by inserting an end into a through-hole 3' of an auxiliary reinforcing bar provided in the reinforcing bar support member A that forms the reinforcing bar support members B1 and B2. Accordingly, the ends of the vertical reinforcing bars 2 are inserted into the through-holes 2 and 2 of the reinforcing bars opposite to each other in the longitudinal direction of one reinforcing bar supporting frame B1 and the other reinforcing bar supporting frame B2, and the reinforcing bars supporting frame facing in the horizontal direction. If the operation of inserting the end of the horizontal reinforcing bar into the through hole 3 of the reinforcing bars B and B is performed, the vertical reinforcing bar 2 and the horizontal reinforcing bar 2 are combined so as to cross each other, and the reinforcing bar to the composite reinforcing bar supporting frame C is combined. The installation is not only stably and reliably performed by the positioning and support of the reinforcing bar 2 by the through-hole 3 even if it is performed by a beginner, but it is also possible to easily place a reinforcing bar for bonding at the bonding corner. The speed was also almost doubled on the data compared to the bar arrangement work performed by the skilled person with the ligatures.

FIG. 11 shows an embodiment of a cylindrical reinforcing bar support frame according to claim 4, and the cylindrical reinforcing bar support frame D shown in this embodiment is the reinforcing bar support frame as shown in FIG. 11. For example, four of B are joined at the side edges in the width direction so that each reinforcing bar support frame B1, B2, B3, B4 forms a rectangular cylinder suitable for, for example, a column, a beam, a girder, etc. To form. And each reinforcing bar frame B1 and B2, B2 and B3, B3 and B4, and B4 and B1 are connected to adjacent reinforcing bars 2 'for joining that correspond to the joining angles. The members B1 and B2, B2 and B3, B3 and B4, and B4 and B1 are arranged by inserting their end portions into auxiliary through-holes 3 'provided at the joint portions. Therefore, the end of the reinforcing bar is inserted into the reinforcing bar through hole 3 of the four reinforcing bar support frames B1, B2, B3, and B4 in the vertical direction and the reinforcing bar through hole 3 of the reinforcing bar support frames B and B in the horizontal direction. If the insertion operation is sequentially performed, the vertical reinforcing bar 2 and the horizontal reinforcing bar 2 are combined so as to cross each other, and even if a beginner performs the installation of the reinforcing bar on the cylindrical reinforcing bar support frame D, the through hole 3 In addition to the stable and reliable positioning and support of the reinforcing bars 2 by means of, it is also possible to easily place the reinforcing bars for joining at the joining corners, and the working speed in this case is also performed by the skilled worker Compared to the bar arrangement work, the data was almost doubled.
