Description

[Technical Field]

[0001] The present invention relates to an assembly auxiliary member for form panels used in formwork. [Background technology]

[0002] Concrete pouring work is carried out when constructing buildings made of reinforced concrete or steel-reinforced concrete. Concrete pouring work involves pouring concrete into a formwork formed by arranging multiple formwork panels on concrete that has been cast on the ground, or what is known as a concrete floor plate, and molding the concrete into the designed shape.

[0003] One example of concrete pouring work is formwork work to cast building foundations. Formwork work is carried out using a formwork in which formwork panels are arranged to match the shape of the target concrete structure. The formwork panels are arranged on the inside and outside of the area where the building foundation will be cast, and a concrete filling space is formed between the formwork panel arranged on the inside and the formwork panel arranged on the outside. When steel formwork panels are used, the top ends of the inner and outer formwork panels are held at a fixed distance by linear separators.

[0004] However, depending on the shape of the building foundation being constructed, the heights of the top ends of the form panels arranged on the inside and the outside may not match, making it impossible to use linear separators for the top ends of opposing form panels. Patent Document 1 lists auxiliary fittings that can connect the top ends of opposing form panels even in such cases.

[0005] Patent Document 1 discloses an auxiliary fitting for mounting a separator in a foundation formwork. The auxiliary fitting includes a foundation formwork crown portion into which the upper end of the foundation formwork fits, and a separator support portion that supports a separator when the foundation formwork crown portion is attached to the upper end of the foundation formwork and whose upper end is approximately flush with the upper end of the other foundation formwork. The auxiliary fitting is configured so that the separator support portion is approximately flush with the upper end of the foundation formwork, allowing a standard separator to be fitted into the upper end of the opposing foundation formwork. The auxiliary fitting is also formed with an open, angular lower end, and two insertion slots, one above the other, are spaced apart along the sidewall of the opening. The foundation formwork crown portion is formed by inserting height-adjustable plates into the insertion slots, allowing it to be fitted into the upper end of the foundation formwork. This allows the auxiliary fittings to adjust the height of the separator support part, making it possible to accommodate multiple levels of step height even if the opposing foundation formworks are at different heights. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2005-320817 Summary of the Invention [Problem to be solved by the invention]

[0007] In current formwork construction, when a step occurs between the upper ends of opposing formwork panels, a roughly L-shaped, standard-sized step separator is used. However, because this step separator is a standard size, it can only accommodate steps of a specific size. As a result, formwork construction contractors have had to take cumbersome measures such as preparing step separators of various sizes or creating handmade separators for each construction site.

[0008] The same is true for the auxiliary fittings of Patent Document 1. Although the auxiliary fittings can accommodate step heights in stages by increasing the number of insertion slots, the number of insertion slots that can be provided on the auxiliary fittings is limited by the size and durability of the auxiliary fittings. Therefore, while the auxiliary fittings can accommodate several levels of step height, it is difficult to accommodate an appropriate step height between opposing formwork panels, just as with approximately L-shaped separators. In actual construction sites, steps between formwork panels that are not of the specified height often occur, so a separator that can adjust the step height to accommodate any step height has been desired.

[0009] Furthermore, even if the upper ends of opposing formwork panels are at the same height, the formwork panel arranged on the inside and the formwork panel arranged on the outside may not be parallel, and there was a need for a separator that could properly connect the upper ends of formwork panels even in such cases. [Means for solving the problem]

[0010] The present invention has been made in consideration of such problems, and its object is to provide an assembly auxiliary member that fixes a rod-shaped member for positioning a form panel to the end of the form panel, and that can appropriately fix the rod-shaped member to the end of the form panel in accordance with various construction environments.

[0011] In other words, the present invention provides an assembly auxiliary member for fixing rod-shaped members for positioning form panels to the ends of form panels when assembling a form in which a plurality of form panels are arranged to form a filled space into which a hardening filler material is poured, wherein the ends of the form panels are provided with a frame plate portion that is formed continuous with the flat panel main body that forms the filled space and is perpendicular to the panel main body, and a rib portion that is formed continuous with the frame plate portion and parallel to the panel main body and forms a recess in the upper part of the panel main body, and the assembly auxiliary member is provided with a substantially U-shaped hook portion whose tip abuts against the inside of the recess to hook the assembly auxiliary member onto the end of the form panel, a support portion that is formed continuous with the hook portion and through which a rod-shaped member abutting against the frame plate portion is inserted, and a pressing portion that presses the rod-shaped member against the frame plate portion from outside the recess and pulls the tip of the hook portion toward the frame plate portion from inside the recess. [Effects of the Invention]

[0012] According to the assembly auxiliary member of the present invention, a rod-shaped member is inserted into the support portion, and the rod-shaped member can be pressed against the frame plate portion from outside the recess by the pressing portion. At the same time, the pressing portion can pull the tip of the hook portion toward the frame plate portion from inside the recess. As a result, the frame plate portion is sandwiched between the tip of the hook portion and the recessed member, and the assembly auxiliary member is attached to the end of the form panel together with the rod-shaped member. Therefore, the assembly auxiliary member can be attached to the end of the form panel simply by pressing the rod-shaped member inserted into the support portion against the frame plate portion with the pressing portion, making it easy to secure the rod-shaped member to the end.

[Figure 7] 1 is an example of a formwork using an assembly auxiliary member of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0014] The assembly assisting member of the present invention will be described in detail below with reference to the accompanying drawings.

[0015] FIG. 1 is a perspective view showing a portion of a formwork constructed using an assembly auxiliary member according to one embodiment of the present invention. The formwork is used in concrete pouring work, which is one step in the construction of a reinforced concrete or steel-reinforced concrete building. In this embodiment, formwork work for forming the foundation of a concrete skeleton will be described as an example. Although FIG. 1 shows a portion of an assembled formwork, for convenience, this portion will be described as formwork 100.

[0016] The formwork 100 comprises a pair of formwork panels 200, a pair of auxiliary assembly members 300 attached to the upper ends of each formwork panel 200, and rod-shaped members 400 supported across each auxiliary assembly member 300 and used to position the formwork panels. The formwork 100 is used by arranging it relative to concrete cast on the ground where concrete pouring work will be carried out, i.e., a concrete floor slab 101. Although not shown in the figure, during actual construction, the formwork panels 200 are connected by separators that maintain a fixed distance between the formwork panels 200, and end plates are provided on the outer edges of each formwork panel 200.

[0017] When the formwork 100 is assembled on the concrete floor slab 101, a filling space 102 into which concrete is poured is formed between the opposing formwork panels 200. The filler poured into the filling space 102 is not limited to concrete, and can be any hardening filler that hardens over time, such as mortar. As an example of the assembly state at the construction site, the formwork 100 in Figure 1 is repeatedly arranged in the front-to-back direction of the page, and the filling space 102 is closed at both ends with members not shown, thereby completing the formwork.

[0018] The pair of form panels 200 are arranged facing each other with a predetermined construction distance between them. The construction distance determines the thickness of the concrete to be cast and can be changed as appropriate depending on the concrete structure to be cast. Form panel 200A, which is arranged on the left side of the paper in FIG. 1, is lower in height than form panel 200B, which is arranged on the right side of the paper. In other words, form panel 200A and form panel 200B have different heights, and there is a step between the top end of form panel 200A and the top end of form panel 200B.

[0019] The form panel 200 has a flat panel body 201. The panel body 201 constitutes the filled space 102 and is the portion that comes into contact with the concrete poured into the filled space 102. In addition, at the upper and lower ends of the form panel 200, there are provided frame plate portions 202 that are formed continuously with the panel body 201 and perpendicular to the panel body 201, and rib portions 203 that are formed continuously with the frame plate portions 202 and parallel to the panel body 201 and form a recess in the upper part of the panel body 201.

[0020] FIG. 2 shows the formwork 100 as viewed from the side. The frame plate portion 202 is the upper end of the formwork panel 200 and is the portion where a regular separator is fitted. The frame plate portion 202 is provided perpendicular to the upper end of the panel body 201. A first corner portion 210A is formed where the panel body 201 and the frame plate portion 202 intersect at a right angle, while a second corner portion 210B is formed where the frame plate portion 202 and the rib portion 203 intersect at a right angle. Therefore, the upper end of the formwork panel 200 is formed concave. Note that the lower end of the formwork panel 200 is configured in the same way, so detailed description of the frame plate portion 202 and rib portion 203 formed at the lower end of the formwork panel 200 will be omitted.

[0021] FIG. 3 is a perspective view of the assembly auxiliary member 300. The assembly auxiliary member 300 is used to fix the rod-shaped member 400 to the end of the form panel 200. The assembly auxiliary member 300 has a support portion 310 that guides the rod-shaped member 400, a hook portion 320 that is formed continuously with the support portion 310 and hooks the assembly auxiliary member 300 onto the end of the form panel 200, and a pressing portion 330 that presses the rod-shaped member 400. The support portion 310 is formed in a substantially U-shape and has a pair of side walls 311 that sandwich the rod-shaped member 400. As shown in FIGS. 1 and 2, the rod-shaped member 400 is inserted between the pair of side walls 311 of the support portion 310. The rod-shaped member 400 sandwiched between the pair of side walls 311 is supported at a certain angle with respect to the assembly auxiliary member 300. Although the rod-shaped member 400 in this embodiment is a square timber having a generally rectangular cross section, any rod-shaped member such as a round pipe or a square pipe may be used.

[0022] This enables the support portion 310 to guide the rod-shaped member 400 relative to the upper surface of the frame plate portion 202. Furthermore, the support portion 310 can guide the rod-shaped member 400 relative to the outside of a first corner portion 210A where the panel main body 201 and the frame plate portion 202 intersect at a right angle, or the outside of a second corner portion 210B where the frame plate portion 202 and the rib portion 203 intersect at a right angle. In other words, the support portion 310 can guide the rod-shaped member 400 relative to the frame plate portion 202 from the outside of the recess.

[0023] The rod-shaped members 400 are inserted through the support portions 310 of the auxiliary assembly member 300A provided at the upper end of the form panel 200A and the support portions 310 of the auxiliary assembly member 300B provided at the upper end of the form panel 200B. The rod-shaped members 400 inserted through the support portions 310 are supported at an incline according to the difference in height between the upper ends of the opposing form panels 200. In this embodiment, the upper end of the form panel 200A is set lower than the upper end of the form panel 200B, and therefore the rod-shaped members 400 supported across the support portions 310 are supported at an incline downward from the upper end of the form panel 200B toward the upper end of the form panel 200A.

[0024] The hook portion 320 is formed in a generally U-shape, extending and curved from the lower portion of the side wall portion 311. The hook portion 320 is provided on each side wall portion 311, and therefore the hook portions 320 are provided opposite each other. The tip portion 321 of the hook portion 320 is formed in a generally semicircular shape. When the assembly auxiliary member 300 is placed at the upper end of the form panel 200, the tip portion 321 of the hook portion 320 can abut against the inside of the recess and be hooked onto the upper end of the form panel 200.

[0025] 2, when the assembly auxiliary member 300A is attached to the upper end of a low form panel 200A, the tip 321 of the hook portion 320 abuts against and is hooked onto a second corner 210B where the frame plate portion 202 and the rib portion 203 intersect at a right angle. On the other hand, when the assembly auxiliary member 300B is attached to the upper end of a high form panel 200B, the tip 321 of the hook portion 320 abuts against and is hooked onto a first corner 210A where the frame plate portion 202 and the panel main body 201 intersect at a right angle. That is, the tip 321 of the hook portion 320 abuts against the underside of the frame plate portion 202, allowing the assembly auxiliary member 300 to be hooked onto the upper end of the form panel 200.

[0026] The pressing portion 330 has a first slit 331A provided in one of the side wall portions 311A, a second slit 331B provided in the other side wall portion 311B, and a wedge-shaped cam plate 333. The first slit 331A and the second slit 331B are provided in opposing side wall portions 311, but these slits are formed so as not to face each other. In other words, the first slit 331A is provided at a position offset from the second slit 331B along the longitudinal direction of the rod-shaped member 400 guided by the support portion 310.

[0027] In the assembly auxiliary member 300 of this embodiment, two tiers of slits 331, one above the other, are provided in each side wall portion 311, but this configuration is not essential, and it is sufficient if one slit 331 is provided in each side wall portion 311, and the slits 331 are offset along the longitudinal direction of the rod-shaped member 400. Incidentally, by providing two tiers of slits 331, one above the other, in each side wall portion 311 as in this embodiment, it is possible to achieve the effect of improving the degree of freedom in the insertion direction of a cam plate 333, which will be described later.

[0028] The cam plate 333 is inserted across the first slit 331A and the second slit 331B. Therefore, the cam plate 333 is supported at an incline with respect to the assembly auxiliary member 300 according to the amount of deviation between the first slit 331A and the second slit 331B. The cam plate 333 is inclined toward the longitudinal direction of the rod-shaped member 400 guided by the support portion 310. In other words, the cam plate 333 is provided at an incline with respect to the lateral direction of the rod-shaped member 400.

[0029] The cam plate 333 is in contact with the rod-shaped member 400 guided by the support portion 310 while being inserted across the first slit 331A and the second slit 331B. This allows the cam plate 333 to press the rod-shaped member 400 against the upper surface of the frame plate portion 202. In other words, the cam plate 333 can press the rod-shaped member 400 against the frame plate portion 202 from outside the recess. The assembly auxiliary member 300 can adjust the biasing force on the rod-shaped member 400 according to the amount of pressing of the cam plate 333.

[0030] 4 is a schematic diagram showing the contact relationship between the cam plate 333 and the rod-shaped member 400. The cam plate 333 is inclined according to the amount of displacement of the first slit 331A and the second slit 331B, and therefore contacts the rod-shaped member 400 in a linear manner inclined toward the longitudinal direction of the rod-shaped member 400. By contacting the cam plate 333 in a linear manner inclined relative to the rod-shaped member 400 within the range of the amount of displacement, it is possible to prevent the angle between the rod-shaped member 400 and the assembly auxiliary member 300 from changing. Therefore, the cam plate 333 can press the rod-shaped member 400 against the upper surface of the frame plate portion 202 while firmly restricting the rod-shaped member 400. Furthermore, if the thickness of the cam plate 333 is increased, it is possible to prevent the angle between the rod-shaped member 400 and the assembly auxiliary member 300 from changing even when the cam plate 333 is brought into contact with the rod-shaped member 400 in a parallel line. However, by configuring it as in the present invention, it is possible to prevent the angle between the rod-shaped member 400 and the assembly auxiliary member 300 from changing without increasing the thickness of the cam plate 333.

[0031] On the other hand, when the cam plate 333 presses the rod-shaped member 400 against the upper surface of the frame plate portion 202, the hook portion 320 is simultaneously drawn from the lower surface of the frame plate portion 202. In other words, the cam plate 333 can draw the tip portion 321 of the hook portion 320 from inside the recess toward the frame plate portion 202. At this time, the tip portion 321 of the hook portion 320 is drawn from the lower surface of the frame plate portion 202 to the portion of the frame plate portion 202 against which the rod-shaped member 400 is pressed, and abuts against the frame plate portion 202. Therefore, a portion of the frame plate portion 202 is sandwiched between the rod-shaped member 400 and the tip portion 321 of the hook portion 320. As a result, the assembly auxiliary member 300 and the rod-shaped member 400 are fixed to the upper end of the form panel 200. In order to strengthen the fixation of the assembly auxiliary member 300 and the rod-shaped member 400 to the upper end of the form panel 200, the rod-shaped member 400 may be provided with a sleeve for improving friction. This improves the frictional force at the contact point between the cam plate 333 and the rod-shaped member 400 and at the contact point between the rod-shaped member 400 and the upper end of the form panel 200, and the assembly auxiliary member 300 and the rod-shaped member 400 are firmly fixed to the upper end of the form panel 200.

[0032] 2, the assembly auxiliary member 300A attached to the upper end of the low-height form panel 200A presses the rod-shaped member 400 guided by the support member 310 against the corner 210B with the cam plate 333, while drawing the tip 321 of the hook member 320 toward the corner 210B. The assembly auxiliary member 300B attached to the upper end of the high-height form panel 200B presses the rod-shaped member 400 guided by the support member 310 against the corner 210A with the cam plate 333, while drawing the tip 321 of the hook member 320 toward the corner 210A. In this way, each assembly auxiliary member 300 is attached to the upper end of each form panel 200 and can support the rod-shaped member 400 along the angle of the difference in height between the upper ends of the opposing form panels 200. In this way, the assembly auxiliary members 300 are attached to the upper ends of the opposing form panels 200, and each assembly auxiliary member 300 fixes one rod-like member 400 across the end of each form panel 200, thereby enabling the rod-like member 400 to position the opposing form panels 200. Note that, in the above description, an example has been given in which the assembly auxiliary member 300 of this embodiment is attached to the upper ends of the form panels 200, but the attachment location of the assembly auxiliary member 300 is not limited to the upper ends of the form panels 200, and there are no restrictions on the attachment location as long as it is an end having the frame plate portion 202 and the rib portion 203.

[0033] The part of the frame plate part 202 that is sandwiched between the rod-shaped member 400 pressed against the frame plate part 202 by the cam plate 333 and the tip end 321 changes depending on the relative height of the step that occurs between the upper ends of the opposing form panels 200. Therefore, when attaching the assembly auxiliary member 300 to a low form panel 200, the part of the frame plate part 202 that is close to the corner part 210B is sandwiched between the rod-shaped member 400 and the tip end 321, whereas when attaching the assembly auxiliary member 300 to a high form panel 200, the part of the frame plate part 202 that is close to the corner part 210A is sandwiched between the rod-shaped member 400 and the tip end 321.

[0034] The angle of the assembly auxiliary member 300 can be adjusted using the contact point between the tip portion 321 and the underside of the frame plate portion 202 as a fulcrum. Since the tip portion 321 in this embodiment is formed in a substantially semicircular shape, the angle of the assembly auxiliary member 300 and the rod-shaped member 400 can be easily adjusted. Therefore, the assembly auxiliary member 300 can freely set the inclination angle of the rod-shaped member 400 that it regulates, and can respond steplessly to the difference in height between the opposing form panels 200.

[0035] In the above description, the pressing portion 330 has a first slit 331A, a second slit 331B, and a cam plate 333, but it is not necessarily configured in this manner. The design of the pressing portion 330 can be modified as appropriate as long as it can press the rod-shaped member 400 guided by the support portion 310 against the upper surface of the frame plate portion 202 and draw the tip portion 321 of the hook portion 320 toward the lower surface of the frame plate portion 202. However, from the viewpoint of regulating the position of the rod-shaped member 400, it is preferable that the pressing portion 330 be configured to come into contact with the rod-shaped member in an inclined line and press it toward the upper surface of the frame plate portion 202.

[0036] In this embodiment, an example has been described in which the opposing form panels 200 are different in height, but this can also be used when the opposing form panels 200 are the same in height. Even in this case, the assembly auxiliary member 300 can be attached to the upper end of each form panel 200 using the same procedure as described above.

[0037] As described above, the assembly auxiliary member 300 can guide the rod-shaped member 400 by the support portion 310 and press one end of the rod-shaped member 400 against the frame plate portion 202 by the pressing portion 330. At this time, the tip portion 321 of the hook portion 320 is pulled from the opposite side of the frame plate portion 202 against which the rod-shaped member 400 is pressed, and a specific portion of the frame plate portion 202 is sandwiched between the rod-shaped member 400 and the tip portion 321. Therefore, the assembly auxiliary member 300 can be attached to the end of the form panel 200 simply by pressing the rod-shaped member 400 with the pressing portion 330, so that the rod-shaped member 400 inserted through the support portion 310 can be easily fixed to the end of the form panel 200. As a result, the rod-shaped member 400 can position each form panel 200.

[0038] Furthermore, the angle of the assembly auxiliary member 300 and the rod-shaped member 400 can be adjusted with the tip end 321 as a fulcrum. As a result, the assembly auxiliary member 300 can fix the rod-shaped member 400 in an inclined state together with the assembly auxiliary member 300 attached to the upper ends of form panels 200 of different heights. Therefore, the assembly auxiliary member 300 can be used to connect the upper ends of form panels 200 of different heights, and since the height of the step that can be accommodated can be adjusted steplessly, the upper ends of form panels 200 of different heights can be easily connected.

[0039] 5, the assembly auxiliary member 300 can fix the rod-shaped member 400 and the assembly auxiliary member 300 to the upper ends of the form panels 200 at a predetermined angle by sandwiching the frame plate portion 202 between the support portion 310 and the tip portion 321, so that the upper ends of the form panels 200 can be connected together even if the opposing form panels 200 are not parallel to each other. Therefore, the assembly auxiliary member 300 can connect the upper ends of the form panels 200 together depending on various construction environments such as the specifications of the building foundation to be constructed and the topography.

[0040] 6 shows an example of how to use the assembly auxiliary member 300. The angle of the assembly auxiliary member 300 itself and the rod-shaped member 400 can be changed as desired, so that the rod-shaped member 400 can be fixed at an angle facing the concrete floor slab 101. This allows the assembly auxiliary member 300 to function as a pressing member that supports the rod-shaped member 400, which is used to position the form panel 200, from the outside of the form panel 200.

[0041] As described above, various uses of the assembly auxiliary members 300 are possible, and Fig. 7 is one example. Fig. 7 shows a formwork assembled on the ground, with the assembly auxiliary members 300 attached to the upper and lower ends of the form panels 200. Rod-shaped members 400 are inserted through the support portions 310 of each assembly auxiliary member 300, and one end and the other end of the rod-shaped members 400 are pressed against the frame plate portions 202 by the pressing portions 330 of each assembly auxiliary member 300. As a result, the rod-shaped members 400 are fixed along the height direction of the form panels 200 by the assembly auxiliary members 300 attached to the upper and lower ends of the form panels 200.
