[0003]
The concrete wall is formed by placing concrete between panel-shaped concrete molds facing each other at a predetermined interval. When concrete is placed between concrete panels in this way, the concrete wall is placed. An extremely large lateral pressure acts on the concrete panel due to the pressure of the concrete.
For this reason, the concrete panel is supported and fixed by the carrier so that the concrete panel is maintained at the initially set interval by preventing the concrete panel from being deformed or displaced, until the concrete driven between the concrete panels is hardened. ing.
[0004]
Conventionally, as a method for supporting such a concrete panel, there is a method in which a steel tube having a circular or rectangular cross section is assembled in a lattice shape and supported (see FIGS. 7 and 8). FIG. 7 is an explanatory diagram when the state in which the supporting means is applied to the outer surface of the concrete panel (10) is viewed from the outside. In the figure, the broken line indicates the vertical steel pipe (40) at this time, and the solid line indicates the horizontal steel pipe (30, 30 ') spanned in the horizontal direction. For comparison, the case where the support 5 according to the present invention is provided is also indicated by a solid line. In explaining the prior art, the circular support 5 shown in FIG. 7 is not considered. FIG. 8 is a cross-sectional view of the main part when the concrete panel (10) provided with the supporting means is viewed from the side.
In FIG. 7, 10 is a concrete form formed in a panel shape, and vertical and horizontal pipes 40, 30, 30 ′ are assembled in a lattice shape in order to press the panel 10 arranged to face each other. . At this time, as shown in FIG. 8, the interval defining tool 4 is screwed to the end of the shaft-like connecting rod (separator) 3 spanned between the panels 10 facing each other, and the other end of the interval defining device 4 is further engaged. The main body 2a of the fixing means 2 such as foam tie (registered trademark) is screwed into the shaft foot 14 formed in the above.
The main body 2a of the fixing means 2 protrudes outward from between the two pipes 30 and 30 'which are spanned in parallel in the lateral direction outside the panel 10, and the horizontal pipes 30 and 30' The plate 41 ′ that can be engaged with is fixed to the fixing means, and then tightened with a nut 2 c or the like, and fixed to the outer wall surface of the concrete panel 10. When the nut 2c of the fixing means 2 is tightened, the horizontal pipes 30, 30 'locked to the contact plate 41' are pressed toward the panel 10, and the vertical pipes pressed by the horizontal pipes 30, 30 'are pressed. 40 is pressed against the outer surface of the panel 10 to carry the concrete formwork.
[0005]
In the concrete panel carried by the conventional means (assembled steel pipe) having the above-described configuration, the area of the carried panel 10 that is actually sandwiched between the space defining tool 4 and the fixing means 2 is extremely small. A large number of pipes (40, 30, 30 ′) are brought into contact with the outer surface of the panel 10 so that the side pressure acting on the panel 10 can be dispersed by the pipes. For this reason, it is necessary to use a large amount of pipes (40, 30, 30 ′), and it is necessary to spend a great deal of labor and cost for transportation and installation, as well as a vast space and labor for storage and management.
In order to reduce the number of pipes used for this, concrete mold carrier of JP-A-11-190127, concrete support jig of JP-A-2002-155623, JP-A-2002- A concrete mold carrier disclosed in Japanese Patent No. 167963 is known. Of these, FIG. 9 shows an example of a concrete form carrier of JP-A-11-190127.
[0006]
[Problems to be solved by the invention]
[Concrete form carrier of JP-A-11-190127]
However, the concrete form carrier of Japanese Patent Application Laid-Open No. 11-190127 is provided when the support 50 is pressed against the plywood form 12 (hereinafter, using the reference numerals given in the above publication) or the holding plate 70. The flange 54 is configured to be elastically deformed so that it can be uniformly and reliably pressed against these surfaces, and the support 50 itself lacks the action of pressing down the outer surfaces of the plywood mold 12 and the presser plate 70. It is not a substitute for the vertical pipe 92 or the tree 92 '.
[0007]
[Concrete support jig of JP 2002-155623 A]
The concrete support jig of Japanese Patent Laid-Open No. 2002-155623 is intended to increase the contact area between the plywood form 1 (hereinafter, using the reference numerals given in the above publication) and the outer wall surface of the presser plate 30. The metal cap-like body 33 is provided with the depressed portion 26. However, in this configuration, the contact area between the pipe 3 and the metal cap-like body 33 decreases on the contrary, and the metal cap-like body 33 is provided. The support of the pipe at the top of the tube will be unstable.
In addition, when a rectangular square pipe is used as the horizontal pipe 3, the depressed overhanging concave portion 45 formed on the bottom surface side of the metal cap-shaped body 33 is a storage portion for the square pipe contact plate 43 for fastening the square pipe. Since the through-hole 38 opened in the center of the metal cap-shaped body 33 is a round hole, the metal cap-shaped body 33 is inserted into the through-hole 38 by inserting the foam tie 6 into the concrete mold. The positions of the recessed and extended recesses 45 when being brought into contact with the frame 1 are not always aligned and arranged in one direction. In this case, when a square pipe is used as the horizontal pipe, after the nut 8 is tightened and fixed, it is necessary to align the depressed and extended recess 45 that functions as a storage portion for the square pipe contact plate 43. In such a case, the adjustment must be performed by loosening the nut 8 again, resulting in poor working efficiency.
Therefore, in such a concrete formwork holding jig (supporting tool), when a square pipe is used as a lateral pipe, the square pipe clamping plate for fastening the square pipe is directed to the support tool. It is desirable to have a structure that can be freely arranged regardless of the direction in which it is present.
In addition, in the concrete supporting jig disclosed in the above-mentioned publication, the square pipe abutting plate 43 for fastening the square pipe is brought into direct contact with the formwork 1, so that a strong force is exerted on the abutting plate itself. If is added, the mold 1 may be damaged.
Therefore, assuming that such a square pipe fastening plate for tightening the square pipe is used, the bottom of the square pipe fastening plate for fastening the square pipe can be stably placed on the support. It is desirable that the force applied to the plate can be effectively dispersed on the concrete panel.
[0008]
[Concrete formwork carrier disclosed in JP 2002-167963 A]
In the concrete mold carrier of JP-A-2002-167963, the pressing metal fitting 80 (hereinafter, the reference numerals given in the above-mentioned publications are used) has a special shape, so that the nut 66 is screwed from above. Fixing is essential, and in carrying out the work per carrier tool, the nuts must be attached to the electric drill and then tightened, resulting in poor work efficiency and a problem of construction delay.
Further, since it is not possible to use a fastening metal fitting (washer or the like) that is used when a concrete form frame is supported by metal pipes that are combined in the vertical and horizontal directions, it is problematic in terms of cost.
[0009]
Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks of the prior art. In short, the present invention can be used at low cost and can be applied quickly, and has a high performance for supporting a concrete panel. It is an object of the present invention to provide a concrete panel carrier that does not damage the surface of the concrete panel.
[0010]
In other words, it has a support that has a shape suitable for stably placing and holding the square pipe abutment plate for tightening the square pipe without spending any special effort, and in addition, the deformation of the support itself is effective. This is a concrete panel supporter that can be prevented easily and can firmly support the concrete panel, reduce the number of pipes and trees used, and use pipes and trees depending on the size of the concrete wall to be formed. Providing concrete panel holders that can reduce the labor and cost of installation work, transportation, and storage due to the reduced use of pipes and wood by reliably supporting concrete panels without having to The purpose is to do.
[0011]
The present invention is also composed of a commercially available foam tie provided with a slit and a wedge that can be inserted into the slit, and is used in combination in combination. It is an object of the present invention to obtain a concrete panel carrying tool that can be diverted and can be fixed quickly and reliably only by a wedge driving operation, and to obtain a concrete panel carrying method using the same.
[0012]
[Means for Solving the Problems]
The present inventor does not interfere with the square pipe abutment plate for clamping the square pipe and the support member to interfere with each other, and does not interfere with the concrete placement work. As a result of intensive investigations to obtain a concrete panel support that can effectively suppress deformation of the support and a support using the same, even when applied directly to The present invention has been completed by finding out that the above-mentioned object can be achieved by using the carrier.
In order to achieve the above object, a concrete panel carrier according to the present invention includes a connecting rod spanned between opposing concrete panels, attached to both ends of the connecting rod, and in contact with the inner wall surface of the concrete panel. A space defining tool that defines the space between the panels, and a shaft foot that protrudes further outward from the space defining tool from the outer wall surface side of the concrete panel, and fixes the concrete panel between the space defining tools. A concrete panel carrier provided with a fixing means that includes a support tool that is inserted through and attached to a body of the fixing means on an outer wall surface side of the concrete panel, and the support tool is provided outside the concrete panel. A hollow substantially frustoconical body formed with a bowl-shaped annular base that abuts against the wall surface in surface contact. Comprising a reinforcing groove, the substantially central portion of the top surface is characterized in that said fixing means are insertion holes for inserting possible substantially rectangular is formed.
[0013]
A concrete panel carrying method according to the present invention is a concrete panel carrying method using a concrete panel carrying tool having the above-described features,

And a step of driving a wedge into a slit provided in the main body and fixing the square pipe abutting plate for fastening the square pipe, the steel pipe and the support between the concrete panel. Is.
[0014]
The support according to the present invention can be applied to any case where two lateral pipes are used in parallel, when used alone, or when there is no lateral pipe. It is. In the case where the square pipe is spanned in the lateral direction, the square pipe fastening plate for fastening the square pipe is directly applied to the upper surface of the support and pressed. This abutment plate is placed between the reinforcing grooves provided on the upper surface of the support tool, and is stably held on the upper surface of the support tool.
[0015]
Moreover, it is preferable that the reinforcing groove provided in the support according to the present invention is formed in a cross beam shape on the upper surface of the support. The interval between the two reinforcing grooves extending in parallel with each other is set such that the square pipe clamping plate for clamping the square pipe can be held sufficiently stably between them. Therefore, even if a large force is applied to the upper surface of the support tool from the square pipe contact plate for tightening the square pipe, the upper surface of the support tool may be recessed. There is no. In addition, the force applied from the square pipe clamping plate for tightening the square pipe is further dispersed from the upper surface of the support and reaches the concrete panel. No damage to the surface will occur.
[0016]
Furthermore, the deformation of the support itself can be minimized by forming the support itself using a relatively thick steel plate or the like, and the bottom surface of the bowl-shaped annular base portion maintains parallelism with the plane of the concrete panel. It is pressure-welded as it is. Accordingly, the contact area between the support and the concrete panel is sufficiently secured, so that the concrete panel can be stably supported.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described.
[0018]
In the concrete panel supporting tool of the present invention, a separator 3 as a connecting rod spanned between concrete panels, a spacing defining tool 4 such as a washer, a P-con or a sharp P-con attached to the separator 3, and this spacing defining tool 4 About the point provided with the fixing means 2 (2a, 2b) connected with the shaft leg 14 provided in this, it is the same as that of the support tool of the concrete panel which concerns on the prior art demonstrated previously. Although the engagement relationship of these members is as shown in FIG. 1, the construction flow will be briefly described below.
[0019]
In other words, the space defining tool 4 is attached to both ends of the separator 3 that spans between the two concrete panels 10 facing each other and contacts the inner wall surface of the concrete panel 10 to define the distance between the concrete panels. The main body 2 a of the fixing means 2 is attached to the other end of 4. The shaft foot 14 of the spacing defining tool 4 is protruded from the outer wall surface of the concrete panel 10, and the main body 2a of the fixing means 2 is screwed from the outside of the concrete panel. The support 5 is inserted and attached to the main body 2a. Thereafter, when the wedge 2b is driven into the slit 12 provided in the main body 2, the support 5 is pressed against and fixed to the concrete panel 10 directly or via the pipe 30 and the contact plate 41 (see FIG. 1, FIG. 4, FIG. 6).
[0020]
【Example】
Next, a preferred embodiment of the present invention will be described below with reference to the accompanying drawings.
[0021]
FIG. 1 is a cross-sectional view of a principal part of a concrete panel carrier according to the present invention.
In the figure, 5 is a support, 7 is a reinforcing groove, 11 is an insertion hole, 41 is a square pipe abutment plate for fastening a square pipe, 2 is a fixing means, preferably a metal fitting commercially available as a foam tie. 3 is a separator, 10 is a concrete panel, and 30 is a pipe extending in the horizontal (horizontal) direction. In addition, although the member etc. which are marketed as a washer, P-con, or a sharp P-con, etc. are mentioned as the space | interval definition tool 4, the member marketed as P-con is suitable in a present Example.
As the fixing means 2, various types of foam ties (registered trademark) are currently marketed, but a slit 12 is formed in the middle of the shaft-shaped main body 2 a, and the slit 12 It is preferable that the fixing wedge 2b can be inserted into the.
In the present embodiment, the support 5 is made of a steel plate having a thickness of 2 mm, and the formation of the reinforcing groove 7, the body portion 13 and the bowl-shaped annular base portion 8 is carried out integrally by pressing.
[0022]
Next, FIG. 2 is the figure which looked at one Example of the support tool based on this invention from the upper surface. Hereinafter, the configuration of the support according to the present embodiment will be described with reference to FIGS. 1 and 2.
The support 5 in the present embodiment is a hollow substantially truncated cone having a bowl-shaped annular base 8 that is in contact with the outer surface of the concrete panel 10 in surface contact. Reinforcing grooves (7a to 7d) are formed on the upper surface of the support tool 5, and an insertion hole 11 for penetrating the main body 2a of a shaft tie-shaped body of Foam Tie (registered trademark) is formed in the center portion thereof. ing. The annular base portion 8 is provided with at least one support fixture fixing nail hole 9 so that the support fixture 5 can be directly secured to the concrete panel 10 and temporarily fixed.
[0023]
[Strengthening groove]
Further, as shown in FIG. 2, each of the reinforcing grooves (7 a to 7 d) extends straight from end to end on the upper surface 6 of the base portion 13.
In this embodiment, the two reinforced grooves (7a, 7b) forming one set extend in parallel while maintaining a certain distance around the insertion hole 11, and another set of reinforced grooves 2 orthogonal to this. Similarly, the book (7c, 7d) extends in parallel while maintaining a certain distance around the insertion hole 11. Therefore, the reinforcing grooves 7 a to 7 d are formed in a cross beam shape on the upper surface 6 of the support 5. The distance between the two reinforcing grooves (7a, 7b or 7c, 7d) extending in parallel is approximately 70 mm in this embodiment. In this embodiment, each set of reinforcing grooves (7a and 7b, or 7c and 7d) sandwiches the insertion hole 11 in the middle and extends in parallel with the long side or short side of the insertion hole. The reinforcing groove extends to the peripheral edge 16 on the upper surface of the support member. Therefore, a part of the peripheral edge 16 is cut out in a side view.
In this embodiment, the width of each of the reinforcing grooves (7a to 7d) is about 10 mm, and the groove depth is about 10 mm. The cross-sectional shape of the reinforcing grooves (7a to 7d) may be rectangular or semicircular, or may be appropriately polygonal.
[0024]
In this embodiment, the reinforcing grooves 7a to 7d are formed in a cross-beam shape on the upper surface 6, and the interval between the two reinforcing grooves (7a, 7b or 7c, 7d) parallel to each other is set for a square pipe for fastening the square pipe. An appropriate interval according to the width of the contact plate 41 is set. By adopting such a configuration, the square pipe contact plate 41 for fastening the square pipe is stably held on the upper surface 6 of the support.
Even if a force is applied to the support tool from the square pipe clamping plate 41 for tightening the square pipe, the support tool 5 may be bent due to the reinforcement effect of the support grooves by the reinforcing grooves 7a to 7d. Therefore, the possibility of dents and deformations is eliminated as much as possible.
[0025]
[Construction method]
Next, a concrete panel carrying method using the concrete panel carrying tool according to the present embodiment will be described.
First, the separator 3 with the interval defining tool 4 attached to both ends is temporarily fixed to a reinforcing bar or the like embedded in the concrete wall after completion, for example, and arranged at a predetermined interval.
When the arrangement of the separator 3 is completed, one of the concrete panels 10 arranged to face one end of the separator 3 is raised.
The concrete panel 10 is provided with an opening 15 corresponding to the position where the separator 3 is arranged, and the concrete panel is raised, and a shaft leg that protrudes outward from the space defining tool into the opening 15 is provided. 14 is inserted.
When the shaft foot 14 is inserted into the opening 15, the shaft foot 14 protrudes from the outer surface of the concrete panel 10, and the main body 2 a of the fixing device 2 is attached to the protruding shaft foot 14 by screwing. After that, the main body 2a is inserted into the insertion hole 11 formed in the upper surface of the support tool 5 to fit the support tool 5, and the wedge 2b is inserted into the slit 12 on the side surface of the main body 2a. To fix.
[0026]
FIG. 3 shows a state in which the support 5 of the present embodiment described with reference to FIGS. 1 and 2 is constructed by the method described above. The main body 2a, the wedge 2b, and the square pipe fixing presser plate 41 are not shown and are omitted. In the figure, 33 is a tree provided on the side of the panel 10, and when the panels are continuously arranged in the horizontal direction, adjacent trees are connected to each other by a nail or the like.
FIG. 3 shows an example in which a concrete wall having a height of 3 m, a width of 4 m, and a thickness of about 400 mm (not shown) is formed. In the vertical direction, the height is 1800 mm (L1) and 1200 mm ( L2) panels are provided continuously in the vertical direction. On the other hand, the width of the panel in the horizontal direction is 900 mm, and the panels are continuously arranged in the horizontal direction as necessary. In the present embodiment, eight support members 5 are arranged per one panel 10 having a size of the above width 900 mm × height 1800 mm (L1). In this embodiment, two supports 5 are also arranged in the width direction on the joints of the upper and lower panels. When constructing a concrete wall of the scale illustrated in FIG. 3, in the construction method of supporting a concrete panel with a conventional steel pipe, as shown by a broken line in FIG. When it was necessary to arrange the steel pipe, if the support according to this embodiment is used, there is no need to provide a separate pipe in the vertical direction, and the vertical reinforcement is performed only by the trees 33 provided at both ends in the width direction of the panel. We can cope enough. In this embodiment, the pipe is a 60 mm square rectangular steel pipe, and the wood 33 is 30 mm wide, and the length of the concrete wall in the thickness direction is 60 mm, which is the same as the width of the rectangular steel pipe.
[0027]
Further, the support 5 of the present embodiment is used not only when the lateral pipe 30 is constituted by a single pipe as shown in FIG. 1, but also when the two pipes (30, 30 ') are closely parallel. Is also applicable (FIGS. 4 and 5). At that time, as shown in FIG. 4 or 5, the two pipes 30 and 30 ′ are arranged with a slight gap therebetween, and the main body 2 a of the fixing means 2 extends through the gap.
[0028]
Furthermore, although depending on the scale of the concrete wall to be constructed, it is also possible to carry the concrete panel only by the support according to the present invention without laying pipes in the lateral direction (see FIG. 6). The working time and cost are greatly reduced compared to the case of installing a pipe. At this time, a plurality of slits are provided on the axis of the main body 2a. On the other hand, the distance (height) between the outer surface of the concrete panel 10 and the upper surface 6 of the support 5 is the diameter of the steel pipe or the length of one side. Therefore, the various metal fittings (2a, 2b, 41) can be used in the same manner as used for ordinary steel pipes.
[0029]
In the present embodiment, the shaft leg 14 is provided at one end of the interval defining tool 4. However, since the separator 3, the shaft leg 14, and the main body 2a of the fixing means 2 are arranged on the same axis, for example, Even if the separator 3 and the shaft foot 14 are integrally formed and the gap defining tool 4 having a threaded hole is screwed into the separator 3 or the body 2a of the fixing means 2, The support 5 according to the present embodiment can be used in the same manner even when the shaft foot 14 is integrally formed and the lower end of the shaft foot 14 is screwed into the interval defining device 4.
In the carrier according to the present invention, it goes without saying that a method of fixing the support 5 to the concrete panel 10 by screwing the nut 2c into the thread groove formed in the main body 2a can be used as in the prior art.
[0030]
【The invention's effect】
If the concrete panel carrier of the present invention described in detail above is used, the following excellent effects can be obtained. In particular, fixing means (metal fittings) that can be used in combination with wedges that can be inserted into the slits provided in the main body can be diverted. At this time, the support can be fixed only by driving the wedges into the slits of the main body. Can be quickly achieved, and the working time and labor can be reduced, and as a result, the remarkable effect of contributing to shortening the work period can be obtained.
[0031]
When carrying concrete panels using the carrying tool according to the present invention, the pipes in the longitudinal direction can be greatly reduced. In the conventional case where a concrete formwork is supported by a steel tube, for example, to create a concrete wall having a height of 3 m, a width of 4 m and a concrete thickness of 400 mm using a panel having a width of 900 mm and a height of 1800 mm, 3 Although the vertical pipe of a book was required, when the support tool 5 by one Example of this invention is used, such an extra vertical pipe becomes unnecessary. When this support tool 5 is used, it is sufficient for the support members in the vertical direction to be provided with wooden boards provided at the left and right ends of the concrete panel.
[0032]
The support of the present invention is formed such that the distance between the upper surface of the base and the surface of the concrete panel is substantially the same as the length of the steel pipe in the vertical direction or the thickness of the longitudinally extending wood. Even when such a support is used, various metal fittings such as foam ties, metal plates, and washers that have been used for supporting concrete molds using conventional steel tube can be used without any modification. I can do it. Therefore, there is no need to procure foam ties or other metal fittings by special order, and there is little possibility of shortage of metal parts of the metal fittings, so that the construction of the concrete wall can be performed inexpensively and quickly. In particular, it is very useful that a fixing means by a method of inserting a wedge into a slit can be selected among commercially available metal fittings.
[0033]
In addition, since the hole opened in the central portion of the support is rectangular according to the cross-sectional shape of the fixing means, the support and the reinforcing groove provided on the concrete panel are always uniform in a certain direction. The conventional work for re-adjusting the support tool in accordance with the displacement of the square pipe clamping plate (41) for tightening the square pipe is not required at all, and the work time can be shortened. It also contributes to solving the delay problem. Further, with the above configuration, the bottom portion of the square pipe abutting plate (41) for tightening the square pipe can be stably placed on the central portion of the reinforcing groove arranged substantially in parallel on the upper surface of the support. Even when the square pipe fastening plate (41) for fastening the square pipe is used, the lateral pipe can be fixed stably to the support at all times.
