Description

The present invention relates to a slab form unit and a support frame unit applied to form each of a plurality of floor concrete slabs in a three-dimensional structure such as a multi-story parking lot, a house, a warehouse, and an office.

In general, a slab of, for example, a concrete three-dimensional structure is formed by assembling concrete according to the slab form after the slab form is assembled at a predetermined upper position with respect to the concrete floor. A typical example of this slab formwork is that a plurality of pipe supports are arranged at predetermined positions via a steady pipe, a plurality of large pulls are installed at the upper end, and the joists are pulled over the large pulls. Assembled perpendicularly and assembled by placing plywood on the joists.

The above-described conventional slab formwork requires many and many types of members, has an extremely large number of assembly steps, is complicated in assembly work, has poor workability, and further requires a disassembly process. As a result, the work time required for assembling and disassembling the slab form becomes extremely long, requiring a lot of manpower and the construction period. Further, in order to obtain the accuracy required for the slab formwork, a high skill level is required for the assembling work.

In order to solve the above technical problems, the present inventor has already developed a movable slab form unit (see Patent Document 1). The slab formwork unit includes a base that is movable along the mounting surface, a slab formwork, a lifting device that connects the slab formable to the base so as to be movable up and down, and the lifting device in a predetermined state. And a stabilizing device for stabilizing. The lifting device includes a first link having a lower end pivotally connected to the base, a second link having a lower end movably connected along the base, an intermediate portion of the first link, and a second link And a connecting pin that rotatably connects the intermediate part of the two links. The stabilizer includes a length-adjustable support rod. One end of the support rod is pivotally connected to the second link, and the other end of the support rod can be detachably engaged with an engagement portion provided on the base. Then, by engaging the other end of the support rod with the engaging portion of the base, the lower end of the second link of the lifting and lowering hand device is prevented from moving along the base in the direction of lowering the slab formwork. Is done.

According to the above-mentioned mobile slab formwork unit, the construction efficiency is high compared to the conventional slab formwork described above, and the excellent effect that the required accuracy can be easily obtained and the construction cost can be reduced is achieved. it can. However, on the other hand, it has the following problems.
(1) Overall, the number of parts is large, the configuration is complicated, and the cost is high.
(2) Since it is heavy and cannot be folded into a compact shape, it cannot be said that quick and agile small transportation in a narrow space at a construction site is easy. In addition, a relatively large storage space and transportation space are required, and storage costs and transportation costs are high.
Therefore, further improvement has been demanded.

Each of the mounting holes 60c is positioned on a common axis. In the brace support frame 60 configured as described above, the outer surface of the flat plate main body 60a is brought into contact with the surface on the opposite side in the middle in the longitudinal direction of the column 14, and is fixed by welding. Therefore, the brace support frame 60 includes a U-shaped groove opened on the opposite side. The width of the brace support frame 60 is formed to be narrower than the width of the opposing surface of the support column 14, and the brace support frame 60 has a width of the opposing surface of the support column 14, as shown in FIG. It is arranged in the center of the direction.

The brace connecting frame 62 made of a metal plate is composed of a rectangular flat plate body 62a and a pair of side walls 62b that extend from both sides of the flat plate body 62a at a right angle in one side direction and face each other. There is no. The tops of the side walls 62b having substantially the same shape are formed in an arc shape, and a mounting hole 62c is formed at the center of the arc in each of the side walls 62b. Each of the mounting holes 62c is positioned on a common axis. In the brace coupling frame 62 configured as described above, the outer surface of the flat plate body 62a is located closer to the other end in the horizontal vertical direction than the center in the horizontal vertical direction of the side frame 30 (position closer to the left end in FIG. 2). ) And is fixed by welding. Therefore, the brace connection frame 62 is provided with a U-shaped groove opened downward. The width of the brace connection frame 62 is formed to be narrower than the width of the lower surface of the side frame 30, and the brace connection frame 62 is arranged on the inner side in the width direction (support frame 8 on the lower surface of the side frame 30 as shown in FIG. It is arrange | positioned in the position which shifted | deviated to the inner side with respect to the periphery.

The brace 22 is formed from a square pipe having a square cross section. One end (lower end in FIG. 11) and the other end (upper end in FIG. 11) of the brace 22 are formed in a semicircular shape when viewed from the front, as shown in FIG. A mounting hole 22a is formed in the center of the semicircular shape at one end and the other end of the brace 22, respectively. One end of the brace 22 configured as described above is inserted into the U-shaped groove formed by each of the flat plate body 60a and the side wall 60b in the brace support frame 60, and the mounting holes 22a are respectively inserted into the mounting holes 60c.

The connecting pin 67 and the retaining pin 68 constitute connecting means. To release the connection of the other end of the brace 22 to the brace connection frame 62, the retaining pin 68 inserted into the through hole 67a of the connection pin 67 is removed, and the connection pin 67 is removed from each of the attachment hole 22a and the attachment hole 62c. It is easily accomplished by extracting.

As shown in FIGS. 1, 2, and 14, the other ends of the braces 20 and 22 in the support units 12 and 16 and the brace connection frame 62 are connected to each other to connect the braces 20 and 22, respectively. When each is positioned in the working position, the strut units 12 and 16 are each positioned in the support position. The slab formwork unit 2 is mounted on the mounting surface via the substrates 11a and 15a of the jack members 11a and 15a, respectively. By rotating the jack members 11a and 15a screwed to the lower ends of the columns 10 and 14, respectively, the height from the placement surface to the upper surface of the mold plate 6 is adjusted to a predetermined height. The upper surface is adjusted horizontally. When the slab form unit 2 is viewed from the front, each of the support columns 10 and each of the support columns 14 and the braces 20 and 22 that obliquely connect the support frame 8 support the support frame 8 firmly. 4 and the slab formwork unit 2 are ensured in strength and contribute to stable load support.

When each of the column units 12 and 16 is positioned at the support position, the downward vertical distance from the lower surface of the support frame 8 to the lower end of each of the columns 10 and 14 in each of the column units 12 and 16 is Are defined substantially equally. Due to this configuration, if the protruding lengths of the jack members 11a and 15a from the lower ends of the columns 10 and 14 are adjusted to be the same in advance before the slab formwork unit 2 is placed, the slab Since the adjustment after the mold unit 2 is placed may be fine adjustment, the adjustment work is facilitated. Further, when each of the column units 12 and 16 is positioned at the support position, the outer side surfaces of the supported plates 45 arranged at the upper ends of the columns 10 and 14 are respectively in the horizontal and vertical directions. The substrates 41 and 51 (see FIGS. 6 and 9) of the support columns 40 and 50 are positioned so as to contact or substantially contact the inner side surfaces in the horizontal vertical direction. Due to this configuration, when the connection between the other end of each of the braces 20 and 22 in each of the support units 12 and 16 and each of the brace connection frames 62 is released, the support units 12 and 16 are respectively It is prevented from rotating outward in the horizontal and vertical directions, and a stable placement state of the slab mold unit 2 is ensured.

In the slab mold unit 2 in which each of the column units 12 and 16 is positioned at the support position and placed on the placement surface, the slab mold unit 2 is viewed from the plane, and therefore the support frame 8 is viewed from the plane. All the structural members of the support frame unit 4 except the support frame 8 are arranged so as not to protrude outward beyond the rectangular peripheral surface of the support frame 8. Accordingly, a plurality of the slab mold units 2 are placed on the placing surface in parallel with each other in the horizontal and vertical directions and in the horizontal and horizontal directions, and are connected to each other so as to be separable from each other. The surface can be easily formed.

More specifically, FIGS. 28 and 29 show an embodiment in which a slab form surface is formed by arranging four slab form units 2A, 2B, 2C and 2D in parallel. . In the illustrated embodiment, the slab mold units 2A and 2B and the slab mold units 2C and 2D are arranged such that the horizontal longitudinal outer surfaces of one end frame 32 of each support frame 8 are adjacent to each other. The connecting holes 32a (see FIG. 1) aligned in parallel and aligned with each other are fastened to be separable by bolts and nuts 70. The slab mold units 2A and 2C and the slab mold units 2B and 2D are arranged in parallel so that the horizontal lateral outer surfaces of one side frame 30 in each support frame 8 are adjacent to each other. The connection holes 30a (see FIG. 1) aligned with the bolts and nuts 70 are detachably fastened. As a result, a horizontal rectangular slab mold surface is formed by the upper surfaces of the mold plates 6 of the slab mold units 2A to 2D. In this way, the slab mold surface can be easily enlarged by connecting the slab mold unit 2 in parallel in the horizontal vertical direction and the horizontal horizontal direction so as to be separable from each other.

In each of the slab formwork units 2, each of the connecting rod members 38 in the column units 12 and 16 can be used as a ladder in addition to improving the strength of the column units 12 and 16. It also contributes to improving the performance. Further, as shown in FIG. 18, the casters 72 are detachably mounted on the lower surfaces of the substrates 11a and 15a of the jack members 11A and 15A of the slab mold unit 2, so that the slab mold unit 2 can be separated. It can be used as a movable shelf or a movable work table.

A concrete slab is formed on the slab mold surface by placing concrete on the slab mold surface formed as described above in a known manner. After a predetermined curing period has elapsed, each of the slab formwork units 2 is removed. This demolding is performed by rotating the jack members 11A and 15A in each of the slab mold units 2 to substantially reduce the length of each of the columns 10 and 14, so that the slab mold unit 2 from the mounting surface. By reducing the height to the upper surface of the mold plate 6 in each of the above, it can be carried out easily and reliably.

As is clear from the above description, the slab mold unit 2 and the support frame unit 4 according to the present invention have a short installation time and are easy to remove, and as a whole, the number of parts is small and the configuration is simple. This makes it possible to manufacture at a low cost.

When each of the braces 20 and 22 is positioned at the folding position and one of the column units 12 is positioned at the folding position and the other column unit 16 is positioned at the folding position, the other column unit 12 is positioned. Each of the braces 22 in the other column unit 16 extends below the one column unit 12 in the horizontal vertical direction along the lower surface of the support frame 8.

The folding of the slab mold unit 2 and the support frame unit 4 will be described more specifically with reference to FIGS. First, the connection between the other end of each of the braces 20 and 22 and each of the brace connection frames 62 in the support units 12 and 16 is released, and each of the braces 20 and 22 is connected to each of the supports 10 and 14, respectively. Each of the braces 20 and 22 is pivoted about each of the brace support frames 60 disposed in the middle of each of the braces 20 and 22 so as to extend along the opposite surface in the lower region of each of the columns 10 and 14. The other end of each is positioned at a folding position where it is superimposed on the lower end of each of the columns 10 and 14, respectively. Each of the braces 20 and 22 has a length such that the tip of each of the braces 20 and 22 does not exceed the lower end of each of the columns 10 and 14, respectively, when each of the braces 20 and 22 is positioned in the folded position. Have. This configuration contributes to downsizing of the support units 12 and 16 when folded.

Subsequently, one of the column units 12 is rotated around the rotation axis L1 and positioned at the folding position (see FIGS. 16 and 17). As a result, each of the braces 20 in one column unit 12 is separable into each U-shaped groove of the other brace connecting frame 62 (the brace connecting frame 62 located on the left in FIGS. 16 and 17). Inserted into. Further, each of the one brace support frames 60 in the one column unit 12 is positioned almost directly below the lower surface of each of the side frames 30 of the support frame 8, and each of the columns 10 in the one column unit 12. Are positioned so as to extend almost directly below each of one brace connecting frame 62 (the brace connecting frame 62 positioned on the right side in FIGS. 16 and 17).

Further, the other column unit 16 is rotated around the rotation axis L2 and positioned at the folding position (see FIGS. 16 and 17). When the other strut unit 16 is positioned in the folded position, each of the braces 22 in the other strut unit 16 and each of the other brace support frames 60 are directly below each of the struts 10 in the one strut unit 12, respectively. , Positioned almost without gaps. Since each of the support units 12 and 16 is sequentially positioned immediately below the lower surface of the support frame 8 with almost no gap, the slab form unit 2 is folded to a substantially minimum thickness.

As is clear from the above description, the slab mold unit 2 and the support frame unit 4 according to the present invention are relatively lightweight, can be folded into a compact shape, and are flexible in a narrow space at a construction site. Small transportation is easy, storage and transportation space is reduced, and storage and transportation costs are reduced.

15-17, although the illustration of the jack members 11a and 15a screwed to the lower ends of each of the columns 10 and 14 is omitted, the folding operation of each of the column units 12 and 16 is as follows. The jack members 11a and 15 are mounted on the lower ends of the columns 10 and 14. When each of the column units 12 and 16 is folded, the jack members 11a and 15 are screwed into the lower ends of the columns 10 and 14 almost as much as possible, and the protruding amounts from the lower ends of the columns 10 and 14 are as follows. Should be kept to a minimum. As a result, the overall length of each of the columns 10 and 14 is substantially minimized, so that when each of the column units 12 and 16 is folded, each of the substrates 11a and 15a of the jack members 11a and 15 is Interference with each of the column support frames 40 and 50 is prevented.
