DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] Hereinafter, embodiments 1 to 3 of the load cell mounting bracket for formwork and the formwork structure according to the present invention will be described with reference to the drawings. Note that the embodiments 1 to 3 described below are merely examples of the present invention, and the present invention is not limited to the following embodiments 1 to 3, and can be modified as appropriate within the creative scope of the technical concept of the present invention.
[0010] Embodiment 1. The following describes a formwork load cell mounting bracket 1 and a formwork structure according to the first embodiment of the present invention. First, the formwork structure in which the formwork load cell mounting bracket 1 of the first embodiment is used and a load cell 9 is installed will be described.
[0011] <Formwork structure configuration> The formwork for pouring concrete is constructed by supporting the outside of each of the sheathing panels 2,2 by vertical end members 3a and horizontal end members 3b on both sides of a separator 8a provided to keep the sheathing panels 2,2 at a specified distance, as shown in Figure 1, and the horizontal end members 3b are held down by end member holding fittings 7 fastened by fastening nuts 6 that screw onto threaded rods 5.
[0012] The threaded rods 5 are connected to shafts (not shown) of cones 8b connected to both sides of the separator 8a, respectively, via axles 4 provided at the ends of the threaded rods 5. Note that the form structure shown in Fig. 1 shows a state in which a load cell 9 is provided on the outside of the thick end material pressing bracket 7 on the right side of the figure, using the form load cell mounting bracket 1 of embodiment 1.
[0013] As shown in Figures 3 and 4, the thick end material pressing fitting 7 is composed of a back plate portion 7a in which a threaded rod through hole (not shown) through which the threaded rod 5 passes is formed, and a pair of side plate portions 7b, 7b that are bent 90 degrees from both the left and right sides of the back plate portion 7a and extend so as to face each other. The end surfaces of the pair of side plate portions 7b, 7b are provided with two thick end material abutment portions 7b1 that are cut out according to the outer shape of the horizontal thick end material 3b so that the horizontal thick end material 3b made of a round pipe or the like can be securely pressed, and these two thick end material abutment portions 7b1 are configured to press the two horizontal thick end materials 3b. The members and structures that make up the formwork described above are well known.
[0014] <Configuration of the formwork load cell mounting bracket 1 etc. according to embodiment 1> The formwork load cell mounting bracket 1 of embodiment 1 is provided, for example, on the outside of the end thick material pressing bracket 7 that presses the horizontal end thick material 3b as shown in Figures 1 to 4, i.e., on the opposite side from the end thick material abutment portion 7b1 and the horizontal end thick material 3b, and fixes the load cell 9 installed between the load cell fixing frame 11 and the fixing nut 12.
[0015] (Load cell fixed stand 11) As shown in Figures 5 and 6, the load cell fixing stand 11 is composed of a cell fixing base 11a on which the load cell 9 is installed, legs 11b provided on the underside of the cell fixing base 11a, and a stand installation base 11c provided at the lower end of the legs 11b so as to face the cell fixing base 11a.
[0016] Since the load cell 9 has a disk shape or a low cylindrical shape, the cell fixing base 11a is formed in a circular shape in a plan view to match the shape and size of the load cell 9, and a threaded rod through hole 11a1 through which the threaded rod 5 passes is formed in the center. Therefore, the inner diameter of the threaded rod through hole 11a1 is formed to be larger than the outer diameter of the threaded rod 5 and smaller than the outer diameter of the load cell 9 so that the load cell 9 can be installed.
[0017] The leg 11b is cylindrically shaped to fit the shape and size of the load cell 9, and has a fastening nut accommodating portion 11b1 that accommodates the fastening nut 6 that screws onto the threaded rod 5 and presses the end thick material pressing fitting 7 against the horizontal end thick material 3b, as well as a semicircular tool opening 11b2 that receives a tool such as an adjustable spanner to rotate the fastening nut 6 accommodated in the fastening nut accommodating portion 11b1. Therefore, the leg 11b has an inner width and height that are greater than the width and thickness of the fastening nut 6.
[0018] The frame installation base 11c, like the cell fixing base 11a, is formed in a circular shape in a plan view, and is provided with a fastening nut through-hole 11c1 that is larger than the outer diameter of the fastening nut 6 screwed onto the threaded rod 5. The load cell fixing frame 11 is configured so that the leg 11b, which is provided with the fastening nut accommodating portion 11b1 and the tool opening 11b2, is sandwiched between the cell fixing base 11a and the frame installation base 11c, thereby improving the strength or durability of the entire load cell fixing frame 11.
[0019] (Fixing nut 12) The fixing nut 12 is screwed onto the threaded rod 5 to fix the load cell 9 to the cell fixing base portion 11a of the load cell fixing stand 11, and is also a nut that temporarily fixes the horizontal end thick material 3b via the end thick material holding bracket 7, etc., and is a hexagonal nut like the fastening nut 6.
[0020] <Load cell 9> The load cell 9 is used to measure the lateral pressure applied to the formwork when concrete is poured. It is commonly available and has a disk-like or low cylindrical shape with a threaded rod through hole (not shown) in the center through which the threaded rod 5 passes.
[0021] <How to Use the Load Cell Mounting Bracket 1 of the First Embodiment> Next, a method of using the load cell mounting bracket 1 of the first embodiment configured as above will be described with reference to the drawings.
[0022] As shown in Figure 1, in the formwork structure in which the outsides of the weir plates 2, 2 are held down by end thick material holding fittings 7 via vertical end thick materials 3a and horizontal end thick materials 3b on separators 8a provided to hold the weir plates 2, 2 at a specified distance, each of the end thick material holding fittings 7 on both sides is firmly fastened by a fastening nut 6 that screws onto a threaded rod 5.
[0023] When installing a load cell 9 using the load cell mounting bracket 1 of embodiment 1 in such a formwork structure, the load cell fixing stand 11, the load cell 9, and the fixing nut 12 constituting the load cell mounting bracket 1 of embodiment 1 are passed in this order onto one of the sides, for example, the threaded rod 5 as shown in FIG. 7(a).
[0024] Thereafter, the fixing nut 12 is screwed in to fix the load cell fixing stand 11 to the outside of the end thick material holding fitting 7 as shown in FIG. 7(b), and the load cell 9 is fixed to the cell fixing base portion 11a of the load cell fixing stand 11.
[0025] Next, as shown in FIG. 8(a), the fastening nuts 6 fastening the end thick material holding fittings 7 are loosened, and then concrete is poured into the formwork.
[0026] By loosening the fastening nut 6, the horizontal end thick members 3b etc. are fixed only by the fixing nut 12, so that the lateral pressure acting on the formwork during concrete pouring can be accurately measured.
[0027] To remove the load cell 9 after concrete pouring has been completed, again insert a tool such as an adjustable wrench through the tool opening 11b2 (see Figures 5 and 6) in the leg 11b of the load cell fixing stand 11, tighten the fastening nut 6 as shown in Figure 8(b) to press and fix the end thick material holding bracket 7 against the horizontal end thick material 3b, then loosen the fixing nut 12 that secures the load cell 9 etc. and remove them from the threaded rod 5, and then remove the load cell 9 and load cell fixing stand 11.
[0028] <Summary of the formwork load cell mounting bracket 1 of embodiment 1> As described above, the formwork load cell mounting bracket 1 of embodiment 1 is composed of a cell fixing base portion 11a, legs 11b and a base installation base portion 11c on the outside of the end thick material holding bracket 7, and is equipped with a load cell fixing base 11 having a fastening nut accommodating portion 11b1 that accommodates the fastening nut 6 that fastens the end thick material holding bracket 7 and a tool opening 11b2 for receiving a tool for rotating the fastening nut 6 accommodated in the fastening nut accommodating portion 11b1, and a fixing nut 12 that screws onto the threaded rod 5 to fix the load cell 9 to the cell fixing base portion 11a of the load cell fixing base 11 and temporarily fixes the horizontal end thick material 3b via the end thick material holding bracket 7 etc.
[0029] Therefore, according to the formwork load cell mounting bracket 1 and formwork structure of embodiment 1 of the present invention, the load cell 9, which measures the lateral pressure applied to the formwork when concrete is poured, is attached via a load cell fixing stand 11 provided on the outside of the end thick material holding bracket 7, i.e., on the opposite side of the end thick material abutment portion 7b1, and fixed with a fixing nut 12. Therefore, even if the mounting position of the load cell 9 needs to be changed, the mounting position of the load cell 9 can be easily changed without removing the horizontal end thick material 3b or the end thick material holding bracket 7, thereby improving workability.
[0030] In particular, in the formwork load cell mounting bracket 1 of embodiment 1, the load cell fixing base 11 is configured so that the leg 11b, in which the fastening nut accommodating portion 11b1 and the tool opening 11b2 are provided, is sandwiched between the cell fixing base portion 11a and the base installation base portion 11c, thereby improving the strength or durability of the entire load cell fixing base 11.
[0031] In the formwork load cell mounting bracket 1 of the above embodiment 1, as shown in Figures 6 and 7, the load cell fixing stand 11 is provided with a stand installation base 11c at the lower end of the leg 11b. However, the present invention is not limited to this. For example, it is of course possible to use a load cell fixing stand 11' which omits the stand installation base 11c, as shown in Figures 9(a) to (c) and 10(a) to (c).
[0032] Embodiment 2. The formwork load cell mounting bracket 1 of the above embodiment 1 has been described using the load cell fixing base 11 consisting of the cell fixing base 11a, legs 11b, and base installation base 11c, which are circular in plan view, or the load cell fixing base 11' consisting of the cell fixing base 11a and legs 11b with the base installation base 11c omitted, but the load cell mounting bracket 1' of embodiment 2 will be described using an example in which a rectangular load cell fixing base 13 is used. Note that the fixing nut 12 is the same as that of embodiment 1, and therefore description thereof will be omitted.
[0033] Figures 11(a) to (d) are respectively an oblique view, a bottom view, a front view, and a cross-sectional view along line CC in Figure 11(c) of a load cell fixing stand 13 constituting a load cell mounting bracket for formwork 1' of embodiment 2 of the present invention, and Figure 12 is an oblique view of the load cell fixing stand 13 and end thick material pressing bracket 7' constituting the load cell mounting bracket for formwork 1' of embodiment 2.
[0034] The formwork load cell mounting bracket 1' of embodiment 2 uses a load cell fixing stand 13 consisting of a cell fixing base 13a that is square in plan view and four legs 13b provided on the underside of the four corners of the cell fixing base 13a.
[0035] A threaded rod through hole 13a1 through which the threaded rod 5 constituting the formwork clamping fitting passes is provided in the center of the cell fixing base portion 13a, and the inner diameter of the threaded rod through hole 13a1 is larger than the outer diameter of the threaded rod 5 and smaller than the outer diameter of the load cell 9 so that the load cell 9 can be installed.
[0036] The four legs 13b are rod-shaped, unlike the load cell fixing frames 11, 11' of the formwork load cell mounting bracket 1 of the above-mentioned embodiment 1, and the fastening nut 6 is housed between the outer surface of the thick-end material pressing bracket 7' surrounded by the four legs 13b and the cell fixing base 13a. That is, in the case of the load cell fixing frame 13 of embodiment 2, the space surrounded by the four legs 13b becomes the fastening nut housing section in which the fastening nut 6 is housed, and the space between two legs 13b becomes a tool opening into which a tool such as an adjustable wrench can be inserted.
[0037] At the tip of each of the four legs 13b, a positioning portion 13b1 having a smaller outer diameter than the leg 13b is provided.
[0038] For this reason, as shown in FIG. 12, a threaded rod through hole 7a1' through which the threaded rod 5 passes is provided on the outer surface of the back plate portion 7a' of the end thick material pressing bracket 7' to which the load cell fixing stand 13 of embodiment 2 is attached, and positioning holes 7a2' into which the positioning portions 13b1 of each of the four legs 13b fit are also provided.
[0039] Therefore, according to the load cell mounting bracket 1' for formwork and formwork structure of embodiment 2 of the present invention, the load cell 9 is fixed by the fixing nut 12 to the cell fixing base portion 13a of the load cell fixing stand 13 provided on the outside of the end thick material pressing bracket 7', i.e., on the opposite side of the end thick material abutment portion 7b1'. Therefore, as with the load cell mounting bracket 1 for formwork of embodiment 1, even if the mounting position of the load cell 9 is changed, it is possible to easily change the mounting position of the load cell 9 without removing the horizontal end thick material 3b or the end thick material pressing bracket 7, thereby improving workability.
[0040] In particular, in the case of the formwork load cell mounting bracket 1' of embodiment 2, the legs of the load cell fixing stand 13 are composed of four rod-shaped legs 13b, making it possible to ensure a wide fastening nut storage section and tool opening, which also improves workability.
[0041] Furthermore, according to the formwork load cell mounting bracket 1' of embodiment 2 of the present invention, positioning portions 13b1 are provided at the lower ends of the four legs 13b of the load cell fixing frame 13, and the positioning portions 13b1 are configured to fit into positioning holes 7a2' of the end thick material holding bracket 7'. This makes it possible to prevent the load cell fixing frame 13 from shifting or falling off, improving workability, and also improving the strength or yield strength of the entire load cell fixing frame 13 by fitting the positioning portions 13b1 of the legs 13b into the positioning holes 7a2' of the end thick material holding bracket 7'.
[0042] In the formwork load cell mounting bracket 1' of embodiment 2, the positioning portion 13b1 is provided on each of the four rod-shaped legs 13b, but the present invention is not limited to this, and it is of course possible to omit the positioning portion 13b1.
[0043] Embodiment 3. In the above-mentioned embodiments 1 and 2 of the load cell mounting bracket for formwork 1, 1', and 13, the load cell fixing frames 11, 11', and 13 have been described as being configured by joining a plurality of members, but in the load cell mounting bracket for formwork 1" of embodiment 3, an example of a load cell fixing frame 14 formed by cutting and bending a single metal plate will be described. Note that the fixing nut 12 is the same as that in embodiments 1 and 2, and therefore description thereof will be omitted.
[0044] Figures 13(a) to (f) are respectively a perspective view, a front view, a bottom view, a front view, a left side view, and a right side view of a load cell fixing stand 14 that constitutes a load cell mounting bracket for a formwork 1" of embodiment 3 according to the present invention, and a cross-sectional view taken along line DD in Figure 13(e). Figure 14 is a perspective view of the load cell fixing stand 14 and the thick material pressing bracket 7" that constitute the load cell mounting bracket for a formwork 1" of embodiment 3.
[0045] As shown in Figs. 13(a) to (e), the load cell fixing stand 14 of the load cell mounting bracket for formwork 1" of embodiment 3 is formed by cutting a single metal plate into a rectangle taking into consideration the size of the load cell 9, and then bending it into a U-shape so as to accommodate the load cell 9, thereby providing a back plate portion 14a, a first side surface portion 14b, and a second side surface portion 14c that is shorter in the up-down direction than the first side surface portion 14b, and a threaded rod through hole 14a1 is provided in the back plate portion 14a.
[0046] Two vertical cuts are made in the first side surface portion 14b, and the portion between the two cuts is left as is, while both sides are folded toward the second side surface portion 14c at a point the same as the vertical length of the second side surface portion 14c to provide folded portions 14b1, 14b1, and the portion between the folded portions 14b1, 14b1 is used as a positioning portion 14b2.
[0047] In the case of the load cell fixing stand 14 of the load cell mounting bracket for formwork 1" of embodiment 3, the space surrounded by the back plate portion 14a, the first side surface portion 14b, and the second side surface portion 14c becomes a fastening nut accommodating portion in which the fastening nut 6 is accommodated, and also becomes a tool opening into which a tool such as an adjustable wrench can be inserted.
[0048] For this reason, as shown in FIG. 14, a threaded rod through hole 7a1' through which the threaded rod 5 passes is provided on the outer surface of the back plate portion 7a'' of the thick end material pressing bracket 7'' to which the load cell fixing stand 14 of embodiment 3 is attached, and a square-shaped positioning hole 7a2'' into which the positioning portion 14b2 fits is also provided.
[0049] Therefore, according to the load cell mounting bracket for formwork 1" and formwork structure of embodiment 3 of the present invention, like the load cell mounting bracket for formwork 1, 1' of embodiments 1 and 2, even when the mounting position of the load cell 9 is changed, it is possible to easily change the mounting position of the load cell 9 without removing the horizontal end thick member 3b or the end thick member pressing bracket 7, thereby improving workability, and since the load cell fixing stand 14 is formed in a U-shape, it is possible to ensure a wide opening for tools, which also improves workability in this respect.
[0050] Furthermore, in the formwork load cell mounting bracket 1" of embodiment 3 according to the present invention, a positioning portion 14b2 is provided on the first side portion 14b of the load cell fixing frame 14 and is configured to fit into the positioning hole 7a2" of the end thick material holding bracket 7". This makes it possible to prevent the load cell fixing frame 14 from falling off, improving workability, and also improving the strength or durability of the entire load cell fixing frame 14 by fitting the positioning portion 14b2 into the positioning hole 7a2" of the end thick material holding bracket 7".
[0051] In the formwork load cell mounting bracket 1" of embodiment 3, the positioning portion 14b2 is provided on the first side surface portion 14b of the load cell fixing stand 14. However, the present invention is not limited to this, and the positioning portion 14b2 may be omitted. [Explanation of symbols]
