BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a method frame forming embedded mold and a method frame forming method .
[0002]
[Prior art]
[Patent Document 1]
JP, 52-61331, A As a reinforcement method of the slope of the mountainside and other slopes such as roads and land, a mesh body such as a wire mesh is laid on the slope, and a frame is placed on the mesh body. There is a construction method in which an embedding formwork for molding is arranged and mortar or concrete (hereinafter referred to as mortar) is sprayed to fill the formwork, and a grid-like formwork is constructed on the slope.
[0003]
As shown in FIG. 8, as the above-mentioned embedded formwork for forming a normal frame, a connecting spacer disposed between parallel and opposite mesh-like side molds is provided between two horizontal wires and the wires. Is composed of two longitudinal wires connected to each other, and both ends of the horizontal wire are pivotally connected to the side mold frame around the longitudinal axis so as to be foldable. is there.
[0004]
The above-mentioned embedded mold for forming a frame is carried into the frame construction site in a folded state so that two side molds are overlapped. It is used to form a normal frame by placing the upper and lower main bars in a formwork, supported by horizontal wires, and blowing mortar into and out of the formwork.
[0005]
[Problems to be solved by the invention]
However, in the conventional embedded mold for forming a frame, since the net-shaped side mold and the connecting spacer are directly connected, the side mold becomes an obstacle to work from the side, and the bottom main reinforcement The work of binding to the lower wire rod of the connecting spacer, and the work of binding the star wrap and lower end main bar when wrapping the stirrup (helper bar) around the upper main bar and the lower main bar are very troublesome and workability There was a problem of being bad.
[0006]
In addition, since the mortar spraying operation is restricted from above and from above and below, it is easy for mortar to spray poorly on the back side of the intersection between the spacer and the upper and lower main bars. Furthermore, it is difficult to spray the mortar so as to avoid the spacers and main bars, and when the mortar is sprayed on the spacers and main bars, a part of the mortar rebounds and granulates. By bonding to each other, there is a concern that the mortar is likely to be in a porous state, and the strength of the frame is reduced.
[0007]
The present invention provides saving be one such has been made in light of the problems of the prior art, in law frame forming embedded frame having a coupling spacers, the use of the mesh body as side formwork completely In addition, various operations from the side, such as tying the bottom main bar to the lower part of the connecting spacer, or wrapping a star wrap around the upper and lower main bars It is an object of the present invention to make it possible to easily perform the work of binding the bottom main bars and the work of filling the mold with mortar.
[0008]
[Means for Solving the Problems]
In order to solve the above problem, the present invention takes the following technical means. That is, it is formed in a substantially rectangular shape by a plurality of wires, and has an open portion that is large enough to allow a hand to be put inside the mold , and the low slump mortar does not flow out of the mold. A plurality of connecting spacers are pivotally connected to a pair of side frames that have a framework so that they can be meshed to form an embedded mold frame for forming a legal frame that can be folded and can be self-supported when deployed. (Claim 1).
Here, the so-called “substantially rectangular shape” refers to a shape in which a portion that partially protrudes from the rectangle, such as a shape combining well shapes, as well as a rectangle.
[0009]
Also, the open part is not preferred and the open area at the short side 5cm above is 50 cm ² or more. This is because if the area of one open part is less than 50 cm ² , even if a hand can be put in, the workability deteriorates, and if the short side is less than 5 cm, it is difficult to put in a hand. It is desirable that the opening portion be provided on both of the pair of side frames.
[0010]
The embedded frame for forming a legal frame having the above configuration can be brought into the legal frame construction site with the side frame of the embedded frame for forming the legal frame folded so as to be overlapped. It can be installed at a predetermined position on the surface to be independent.
[0011]
Moreover, when using a mortar with low slump (preferably with a slump value of 0), the mortar will not flow out of the mold as long as there is a framework with a certain degree of alignment. Therefore, the embedded frame for forming a legal frame can be configured with only a framework without using a net .
[0012]
In particular, since the side frame is provided with an open portion that is large enough to allow a hand to be placed inside the mold, the embedded mold for forming a frame always has a working space from the side.
[0013]
Therefore, various work from the side, for example, the work to bind the lower main bar to the lower part of the connecting spacer, or the star wrap and the lower main bar to be used when wrapping a star wrap (helper bar) around the upper main bar and the lower main bar It is possible to easily perform the work to be performed.
[0014]
In addition, when mortar is sprayed inside and outside the mold, filling may occur in the back side in the spraying direction, such as the back side of the main reinforcement, and cavities (sparse parts such as mortar and concrete) may be formed. However, as mentioned above, since the mold is composed of only the framework without using the reticulated side mold, the mortar can be sprayed into the mold from the side of the mold as needed. In addition, it is possible to avoid filling defects on the back side in the blowing direction such as the back side of the main bar, and the quality of the method frame can be improved also from this aspect.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show an example of an embedded mold for forming a legal frame according to the present invention. The embedded frame 1 for forming a normal frame is made of a wire rod (for example, a steel wire rod or a soft iron wire rod), and is configured to be foldable and to be self-supporting when unfolded.
[0016]
The embedded frame 1 for forming a frame is connected to a plurality of (four in the illustrated example) horizontal wires 2 (2a, 2b, 2c, 2d) arranged in parallel and connected thereto by means such as welding. A plurality of (in the illustrated example, four in the illustrated example) a plurality of (in the illustrated example, four in the illustrated example) a plurality of (in the illustrated example, four in the illustrated example) the pair of side frames 4 formed in a rectangular shape with a plurality of (seven in the illustrated example) vertical wires 3 (3a, 3b, 3c, 3d. The connecting spacer 5 is pivotally connected.
[0017]
The vertical wires 3 (3a, 3b, 3c, 3d...) Constituting the side frame 4 are arranged at 15 cm intervals from the adjacent vertical wires 3 (3a, 3b, 3c, 3d...), Respectively. The horizontal wire 2 is disposed with an interval of 7 cm between 2a2b and 2c2d and 15 cm between 2b2c.
The spacing between these wires is not particularly limited, but considering the work efficiency, the distance between the open portions is at least 5 cm or more, preferably 10 cm or more, and the area of the open portions is 50 cm ² or more. It is preferable to configure.
[0018]
The connecting spacer 5 includes two wire rods 7a and 7b that intersect in an X shape within a plane perpendicular to the side frame 4 in a state where the embedded frame for forming the frame is expanded to the use posture, and both wire rods 7a. , 7b and the transverse wires 8a and 8b connected to the upper and lower portions by means of welding or the like, and ring-shaped portions are bent and formed at both ends of each wire 7a, 7b, 8a, 8b. The ring-shaped portion is pivotally attached to the vertical wires 3a, 3b, 3c, 3d of the side frame 4 so as to be rotatable around the vertical axis, and the pair of side frames 4 can be switched between a self-supporting posture and a folding posture, The connecting spacer 5 may be formed in a similar shape using a plate material or a plastic molded product.
The shape of the spacer is not limited to the above, and can be selected as appropriate, such as a well shape or a gate shape.
[0019]
According to the above configuration, as shown in FIG. 2, the embedded frame 1 for forming the legal frame can be carried into the legal frame construction site in a folded state. It can be deployed and self-supported at a predetermined position on the slope, and installed on the slope.
[0020]
Then, for example, as shown in FIG. 3A, the upper main bars 10a and the lower main bars 10b are arranged in a state where they are supported by the necessary number of wires 8a and 8b of the connecting spacer 5, and these main bars 10a, The stirrup 11 is wound and fixed on 10b, and then a low slump mortar 13 is sprayed in and out of the embedded mold for forming the frame to form the frame.
[0021]
In this case, the above-mentioned embedded mold 1 for forming a frame has an open portion that allows a hand to be sufficiently placed in the side frame 4, so various operations from the side, for example, the lower end main bar 10 b is used as the lower wire 8 b. Thus, it is possible to easily perform the operation of binding the stirrup 11 and the bottom main muscle 10b.
[0022]
In particular, according to the above-described configuration, the connecting spacer 5 has a bracing structure in which the two wire rods 7a and 7b intersect each other in the X shape, so that it is very robust and hardly deforms in the width direction. Therefore, when forming the normal frame portion along the contour line, the weight of the main muscles 10a and 10b supported by the connecting spacer 5, especially the operator steps on the main muscles 10a and 10b, or hits other objects against the main muscles 10a and 10b. There is no possibility that the mold will be deformed in the width direction due to an unexpected load at the time of contact, and the quality of the method frame can be improved.
[0023]
Moreover, when the mortar 13 is sprayed and filled in and out of the mold, there may be a filling failure portion on the back side in the spraying direction such as the back side of the main bars 10a and 10b. Further, the connecting spacer 5 is attached to the side frame 4. If it is composed of two wire rods 7a and 7b intersecting in an X shape within a plane perpendicular to each other, and horizontal wire rods 8a and 8b laid horizontally at two upper and lower portions of both wire rods 7a and 7b, When filling the mold with mortar 13 from one end in the longitudinal direction, cavities (sparse parts such as mortar and concrete) can be formed due to poor filling of the connecting spacer 5 to the back side of the X-shaped intersection. However, as mentioned above, the formwork is composed of a frame without using a reticulated side formwork, and the side face of the formwork is widely open. The frame can be filled with mortar 13, 10a, the back side of 10b or the like, the back or spraying direction, defective filling of the rear side of the X-shaped cross section of the connecting spacers 5 can be avoided, can improve the quality of legal frame from this plane.
[0024]
An example of the legal frame construction procedure is described as follows. First, as shown in FIG. 4A, after laying the wire mesh 12 on the slope, the bottom main bar 10b is installed on the wire mesh 12 in a state of being inserted into the stirrup 11 in advance, and the frame is placed on it. After the formation of the forming embedded form 1, the lower end main bar 10 b is bound to the wire 8 b of the connecting spacer 5 with a wire or the like (not shown) as shown in FIG.
[0025]
Thereafter, as shown in FIG. 4C, the star wrap 11 is lifted, and the upper end main reinforcement 10a is placed in the stir wrap 11 on the wire 8a of the connecting spacer 5 and is connected with a wire or the like (not shown). After being bound, the stirrup 11 is bound to the upper main bar 10a and the lower main bar 10b with a wire or the like (not shown), and the bar arrangement work is completed as shown in FIG.
[0026]
In this case, since the opening part is provided on the side surface of the mold, a hand can be inserted into the mold from the side, and the upper end main bar 10a and the lower end main bar 10b are bound to the wires 8a and 8b of the connecting spacer 5. The stirrup 11 can be easily bound to the upper main bar 10a and the lower main bar 10b.
[0027]
Then, as shown in FIG. 5B, low slump mortar 13 is sprayed into and out of the embedded mold for forming the frame, and the mold is filled.
[0028]
In this case, since the skeleton 13 is not used and the side surface is a framework, the mortar 13 can be sprayed from the side into the mold, such as the back side of the main bars 10a and 10b, It is possible to avoid a filling failure on the back side of the X-shaped intersection of the connecting spacer 5.
[0029]
After that, when there is 13 parts of mortar that has adhered too much outside the mold, a desired method frame is constructed by performing surface decorative blowing and / or trowel finishing as necessary.
[0030]
[0031]
FIG. 6 and FIG. 7 show a method frame constructed by the above procedure. In the figure, reference numeral 15 denotes a vegetation base material sprayed in a thick layer on the wire mesh 12 between the frame frames, and 16 denotes an anchor. In addition, as shown in FIG. 6, the embedded frame 1 for forming the frame and the upper main bar 10a, the lower main bar 10b, the stirrup 11 and, if necessary, the side frame network 14 are pre-assembled on a flat ground. Can be suspended to the installation position on the slope.
[0032]
【The invention's effect】
As described above, according to the present invention, in the embedded mold for forming a frame, it is only necessary to serve as a guide for mortar spraying, so the use of a side mold network can be omitted, Cost reduction can be achieved.
[0033]
Moreover, the side frames constituting the mold constituted of only the skeleton, the opening of which can be placed a hand size provided, and, fit eyes of the degree of low slump mortar or concrete is not of flows in the mold outside the frame Since the framework is made to exist , the workability of reinforcement and bundling is improved, and from the upper side, the upper front and back, and the side from the side without being disturbed by the net-like side formwork Since the mortar spraying operation is possible, it becomes possible to avoid poor mortar spraying and porous construction of the mortar, thereby ensuring the improvement of the strength quality of the legal frame.
