  Hereinafter, embodiments of a temporary structure for forming a slab according to the present invention and a method for constructing the temporary structure for forming a slab will be described in detail with reference to the drawings. However, the present invention is not limited by this embodiment.

[Basic concept of the embodiment]
First, the basic concept of this embodiment will be described. The present embodiment schematically relates to a temporary structure for forming a slab for forming concrete by placing concrete at a position distant upward from the foundation, and a method for constructing the temporary structure for forming the slab. Is. The floor area of the slab constructed by this temporary slab forming structure and the purpose of use of the slab are arbitrary. In addition, the floor on which the foundation and the slab are formed is arbitrary, but in the present embodiment, the description will be made assuming that the foundation is the first floor and the slab to be formed is the second floor.

[Specific contents of the embodiment]
Next, specific contents of the present embodiment will be described.

(Embodiment)
First, an embodiment will be described.

(Constitution)
Initially, the structure of the temporary structure 10 for slab formation concerning this Embodiment is demonstrated. FIG. 1 is a perspective view schematically showing a slab forming temporary structure 10 according to the present embodiment. As shown in FIG. 1, the slab-forming temporary structure 10 according to the present embodiment includes a barrier plate 20, a support part 30, a first coupling part 40, and a second coupling part 50. . In the following description, the X direction in FIG. 1 is referred to as the width direction, the Y direction (that is, the direction orthogonal to the XZ plane) as the depth direction, and the Z direction as the height direction as necessary.

(Configuration-target space)
First, the target space 1 in which the slab-forming temporary structure 10 according to the present embodiment is constructed will be described. The target space 1 includes a base portion 2 and a wall portion 3. The base 2 is a slab that forms a first floor formed by a known method. The wall 3 is a known wall configured by connecting a plurality of panels. Note that at least the base portion 2 may be formed in the target space 1, and the wall portion 3 may not be provided.

(Configuration-Temporary structure for slab formation)
Then, each component of the temporary structure 10 for slab formation is demonstrated.

(Configuration-Temporary structure for slab formation-Dam plate)
The dam plate 20 is a casting form in which concrete is cast on the upper surface. The number and shape of the dam plates 20 are arbitrary, and the dam plates 20 having a necessary number and shape are appropriately used according to the shape of the slab to be formed. Moreover, although the raw material of this dam plate 20 is arbitrary, in this Embodiment, it demonstrates as what is a veneer board generally used as the dam plate 20. FIG.

(Configuration-Temporary structure for slab formation-Support section)
The support unit 30 is a support unit that supports the plurality of dam plates 20 by being installed from the base portion 2 to the plurality of dam plates 20. This support part 30 is generally configured to include a column 31 and a base part 32.

  The support 31 is a support means for supporting the base portion 32. The support columns 31 are arranged in parallel on the base portion 2 at a plurality of locations along the width direction and the depth direction, and each support column 31 extends along the vertical direction between the base portion 2 and the large pull 33. Has been placed. The support column 31 is a plurality of support members having lengths corresponding to the height of the slab to be formed, and is a metal rod-like body formed with a strength capable of supporting the load of the slab and the base portion 32. Composed. Here, the support column 31 is generally configured to include a support column 31a and a support column 31b. However, when it is not necessary to distinguish between the support column 31a and the support column 31b, they are simply referred to as a “support column” 31. I will explain.

  The column 31 a is a base part support means for supporting the base part 32. In other words, the support column 31 a is disposed immediately below the base portion 32. Although the specific configuration of the column 31a is arbitrary, a locking piece (not shown) capable of locking the base portion 32 is formed at the upper end of the column 31a in the present embodiment. It is configured such that the end of the base portion 32 can be hooked and locked to the stop piece. As a result, the base portion 32 can be easily assembled. Details of the assembly of the base portion 32 will be described later.

  The column 31 b is a second coupling portion support means for supporting the second coupling portion 50. That is, unlike the support column 31a, the support column 31b is disposed other than directly below the base portion 32. Specifically, as shown in FIG. 1, a plurality of base portions 32 are arranged side by side along the width direction and the depth direction, and the plurality of base portions 32 are arranged so as to be in close contact with each other. And there is a portion arranged with a gap of a predetermined distance from each other, and the column 31b is arranged in the latter gap portion. The reason why the gap portion is provided in this manner is that a known permanent support method is applied in the present embodiment, and the support plate 31b and the weir plate 20 supported by the support column 31b correspond to so-called permanent support portions. In addition, the said construction method is demonstrated briefly below and the said construction method is demonstrated in detail in description of the construction method mentioned later. First, when concrete is placed on the barrier plate 20 and the concrete of the barrier plate 20 realizes early dismantling strength (described later), only the support plate 31b and the support plate 31b supported by the support column 31b are left, Other parts (for example, the column 31a etc.) are disassembled. As described above, the other part (for example, the support column 31a) can be disassembled at an early stage before the design reference strength is realized, and therefore, the other part can be disassembled and diverted early. . After the dismantling, when the concrete achieves the design standard strength (described later), the permanent support portion left on the site is dismantled.

  Here, the “early dismantling strength” is a compressive strength required when disassembling a portion other than the permanent support portion, and is calculated based on the frame type of the slab, the number of support columns 31, the load situation, and the like. The strength is about 50%. The “design standard strength” includes a known design standard strength determined by the Building Standards Law, but is not limited to this, and a compressive strength appropriately determined based on an arbitrary law or the like may be used.

  Although the specific configuration of the column 31b is arbitrary, a substantially upward U-shaped mounting piece (FIG. 1) for mounting the second coupling unit 50 on the upper end of the column 31b in the present embodiment. And the second coupling portion 50 can be mounted on the mounting piece.

  The base portion 32 is a base means that is installed at the upper end of the column 31a and constructs the bases of the plurality of barrier plates 20. FIG. 2 is a perspective view showing the base portion 32. As shown in FIG. 2, the base portion 32 is configured by integrally including a large pull 33 and a joist 34.

  The large pull 33 is a member that is directly supported by the column 31a, and a total of two are arranged below the both ends of the joist 34 in the longitudinal direction so as to be parallel to each other. The two large forks 33 are formed of the same shape and material as each other, and are specifically aluminum materials having a substantially rectangular parallelepiped shape. The shape and material of the large pull 33 are arbitrary, and can be formed of any other shape or material as long as it can withstand the load of the slab.

  The joist 34 is a member that directly supports the barrier plate 20, and is installed above the large pull 33 and perpendicular to the longitudinal direction of the large pull 33 so as to be bridged between the two large pulls 33. Yes. Although the number of joists 34 is arbitrary, in the present embodiment, the description will be made assuming that six joists 34 are arranged in parallel along the longitudinal direction of the large pull 33. Further, the cross section shape of the joist 34 is arbitrary, and may be, for example, a rectangle, but in the present embodiment, it will be described as an inverted trapezoidal shape having a short side as a base. In the following description, it is assumed that the joist 34 has a height of 100 mm (ie, the length from the surface in contact with the large pull 33 to the upper end surface). Further, the joist 34 is also made of aluminum like the large drawer 33.

(Configuration-Temporary structure for slab formation-First coupling part)
The first coupling portion 40 is a coupling means that is coupled to the dam plate 20 and fixes the position of the dam plate 20. Here, “fixing the position of the barrier plate 20” means fixing the position of the barrier plate 20 in the width direction and the height direction in the target space 1, and the barrier plate 20 is warped, This includes preventing the position of the weir plate 20 from shifting. Specifically, the first coupling portion 40 is a crosspiece disposed above the large pull 33 and between the plurality of joists 34 and is disposed along the joints of the plurality of dam plates 20. . And this 1st coupling | bond part 40 has couple | bonded the said dam boards 20 mutually by being nailed and fixed with respect to each dam board 20 which forms these seams.

  Here, the specific shape of the first coupling portion 40 is arbitrary, but in the present embodiment, as shown in FIG. 1, it is formed as a long member whose cross-sectional shape orthogonal to the longitudinal direction is a rectangle. Has been. Here, the height of the first connecting portion 40 is preferably the same as the height of the joists 34 or smaller than the height of the joists 34. In other words, if the height of the first coupling portion 40 is greater than the height of the joist 34, when the first coupling portion 40 is placed on the upper portion 33 as shown in FIG. Although it swells upward, this problem can be solved by setting it to the height of the joist 34 or less. More preferably, the height of the first coupling portion 40 is preferably the same as the height of the joist 34. That is, compared with the case where the height of the first coupling portion 40 is less than the height of the joist 34, the first coupling portion 40 and the dam plate 20 when the first coupling portion 40 is placed above the large pull 33. No gap is formed between the first coupling portion 40 and the weir plate 20, which can be more firmly and stably fixed. In view of the above, the first coupling portion 40 according to the present embodiment is formed to have the same height as the joist 34 (in the present embodiment, 100 mm).

  The first coupling portion 40 may be formed by combining a plurality of materials. For example, in the present embodiment, by placing two pieces of wood having a height of 50 mm in the height direction, A first coupling portion 40 having a total height of 100 mm is configured. Moreover, the 1st coupling | bond part 40 does not need to be wood, as long as the weir board 20 can be couple | bonded mutually.

(Configuration-Temporary structure for slab formation-Second coupling part)
The second coupling unit 50 is mounted on the upper end of the support column 31b and coupled to the dam plate 20 positioned between the plurality of base units 32 to fix the position of the dam plate 20. It is. Specifically, the second coupling portion 50 is an end thick angle placed on the placement portion located at the upper end of the support column 31b and is arranged along the joints of the plurality of barrier plates 20. . And this 2nd coupling | bond part 50 couple | bonds the said dam boards 20 mutually by being nailed and fixed with respect to each dam board 20 which forms these seams.

(How to build)
Then, the construction method of the temporary structure 10 for slab formation concerning this Embodiment is demonstrated later on. In addition, although the person who implements this construction method will be referred to as a “worker” below, this worker is not limited to a single person or a person in the same industry. In addition, the “construction method” according to the present embodiment includes a method of disassembling the constructed temporary structure 10 for slab formation.

  First, the worker performs step 1. FIG. 3 is a vertical cross-sectional view schematically showing step 1. In addition, in FIG. 3, the permanent support part P is illustrated with the imaginary line. In this step 1, the worker assembles the column 31a and the base portion 32. This assembling method is publicly known. For example, after all the columns 31a are erected, the base portion 32 may be placed above them, or two columns 31a and one base portion 32 are set as one set. You may build one set at a time. And the support | pillar 31a and the base part 32 are assembled so that the base part 32 may be arrange | positioned over the whole object space 1. FIG. However, in the present embodiment, in order to realize early disassembly and early diversion of the support column 31a and the base portion 32, an area (the above-described permanent support portion P) where the support column 31a and the base portion 32 are not disposed is provided. The permanent support portion P is usually provided at the center of the slab as shown in FIG. 1. However, the strength of the concrete to be placed on the dam plate 20, the known period of the permanent support portion P, etc. It can be arbitrarily determined based on this.

  Next, the worker performs step 2. FIG. 4 is a vertical sectional view schematically showing Step 2. In step 2, the worker erects the support column 31b on the permanent support part P. In addition, since the standing method of this support | pillar 31 is well-known, the detailed description is abbreviate | omitted.

  Next, the worker performs step 3. FIG. 5 is a vertical cross-sectional view schematically showing step 3. In step 3, the worker moves on the base portion 32 and then places the first coupling portion 40 and the second coupling portion 50 thereon. Here, the position where the 1st coupling | bond part 40 is mounted is a position corresponding to the edge part of each dam plate 20 at the time of laying down the several dam plate 20 on the base part 32 without gap in the operation | work mentioned later. is there. For example, when the width of the barrier plate 20 is W (see FIG. 6 described later), the first coupling portions 40 are arranged at intervals corresponding to the W. Moreover, the position where the 2nd coupling | bond part 50 is mounted is arbitrary as long as the dam plate 20 can be mounted on the 2nd coupling | bond part 50, for example, like the 1st coupling | bond part 40, the dam plate 20 of FIG. Although it may be an end portion, in the present embodiment, it will be described as being arranged at the center position in the width direction of the dam plate 20. Here, the first coupling part 40 is placed without being joined to the base part 32. That is, the worker moves on the base portion 32 and simply places the first coupling portion 40 above the large pull 33 and between the joists 34. Do not perform nailing or the like. Similarly, the 2nd coupling | bond part 50 is mounted, without joining with respect to the support | pillar 31b. In addition, the height of the 2nd coupling | bond part 50 and the height of the support | pillar 31b are adjusted so that the height of the upper end position of the 1st coupling | bond part 40 and the 2nd coupling | bond part 50 may become the same as the height of the upper end position of the joist 34. It is desirable to do.

  Next, the worker performs step 4. FIG. 6 is a vertical cross-sectional view schematically showing step 4. FIG. 7 is an enlarged view of a portion A in FIG. In this step 4, the worker moves over the base portion 32 and then spreads the plurality of barrier plates 20 over the entire upper portion of the base portion 32 without any gaps. Specifically, the worker first lays a plurality of dam plates 20 on the base portion 32 without gaps so that the end portions of the dam plates 20 are placed on the first coupling portion 40 as shown in FIG. To go. And the weir plate 20 and the 1st coupling | bond part 40 or the 2nd coupling | bond part 50 are joined by hitting the nail 41, and the dam plates 20 are mutually couple | bonded and an integral formwork is formed. be able to. In addition, the dam plate 20 located in the outermost periphery among several dam plates 20 is earth | grounded with respect to the existing wall part 3, and this wall part 3 plays the role of the formwork which forms the side surface of a slab.

  Thus, in the present embodiment, by providing the first coupling portion 40 and joining the dam plate 20 to the first coupling portion 40, the dam plate 20 is directly nailed and joined to the base portion 32. It becomes possible to install without. Therefore, unlike the conventional method, no holes are formed in the joist 34 of the base portion 32 when nailing, and the number of diversions of the base portion 32 can be dramatically improved.

  Next, the worker performs step 5. FIG. 8 is a vertical cross-sectional view schematically showing step 5. In step 5, the worker places concrete on the upper side of the dam plate 20 installed in step 4. In addition, since the concrete method of this placement is well-known, the detailed description is abbreviate | omitted. Further, the placed concrete is indicated by “concrete 4” in FIG. 8 and FIGS. 9 and 10 described later.

  Next, the worker performs step 6. FIG. 9 is a vertical cross-sectional view schematically showing step 6. In step 6, the worker disassembles the column 31 a and the base portion 32. In addition, since the concrete method of this disassembly is well-known, the detailed description is abbreviate | omitted. By this disassembly, only the barrier plate 20, the first coupling portion 40, the second coupling portion 50, and the support column 31b remain under the slab, and the load of the slab is supported by the support column 31b. The pillar 31a and the base portion 32 disassembled in this way can be immediately diverted when the slab-forming temporary structure 10 (not limited to that according to the present embodiment) is constructed again in another place. In addition, this process 6 is implemented after the concrete 4 laid in the process 5 realizes the above-mentioned early dismantling strength.

  Here, as described above, since the base portion 32 and the first coupling portion 40 are not joined to each other, it is possible to reduce labor required for disassembling the base portion 32, and to reduce the base portion 32 and the weir. It is possible to reduce the possibility that the plate 20 is damaged. That is, in the conventional construction method, since the dam plate 20 and the base portion 32 are directly nailed, when disassembling the base portion 32, a tool such as a bar is sandwiched between the base portion 32 and the dam plate 20. There was a problem that it was necessary to peel off and so on, which required much labor. Moreover, when peeling the base part 32 from the barrier plate 20, the nail hole provided in the base part 32 may expand, or the barrier plate 20 may be deformed or damaged. There was also. On the other hand, according to the construction method according to the present embodiment, since the base portion 32 and the first coupling portion 40 are not nailed to each other, any of the above problems can be solved.

  Next, the worker performs step 7. FIG. 10 is a vertical sectional view schematically showing the step 7. In step 7, the worker disassembles all the dam plates 20 and the first coupling portions 40 except for the columns 31 b, the second coupling portions 50, and the dam plates 20 included in the permanent support portion P. The dam plate 20 and the first coupling part 40 disassembled in this way are immediately converted when the slab-forming temporary structure 10 (not limited to the one according to the present embodiment) is constructed again in another place. Can do. With the above, disassembly of all the components except for the barrier plate 20, the second coupling portion 50, and the support column 31b included in the permanent support portion P is completed.

  Finally, the constituent elements such as the weir plate 20 included in these permanent support portions P are disassembled after the concrete 4 placed in step 5 achieves the design standard strength described above. These components can also be diverted to other places in the same manner. Even during this disassembly, the second connecting portion 50 is not nailed to the support 31b, so that it is possible to reduce the labor required for disassembling the support 31b, and the support 31b and the dam plate 20 It becomes possible to reduce the possibility of breakage.

(Effect of embodiment)
As described above, according to the present embodiment, since the dam plate 20 and the first coupling portion 40 are placed in a non-joined state with respect to the base portion 32, the dam plate 20 is nailed to the base portion 32, and the like. A plurality of barrier plates 20 can be joined to each other without being fixed by this method, and the diversion efficiency of the base portion 32 that becomes the base of the barrier plate 20 can be improved, and it is safe and easy, and hassle-free And construction with reduced time.

  In addition, since the first coupling portion 40 is placed at a position between the plurality of joists 34 above the plurality of large draws, an existing space is used without providing a space for installing the first coupling portion 40 separately. Thus, the first coupling portion 40 can be installed, and the workability can be improved. In addition, since the height of the first coupling portion 40 and the height of the joist 34 are the same, the upper end of the first coupling portion 40 abuts against the dam plate 20 when the dam plate 20 is placed on the base portion 32. Thus, the first coupling portion 40 can be more easily coupled to the dam plate 20.

  Moreover, since the 2nd coupling | bond part 50 couple | bonded with respect to the dam plate 20 is provided between the some base parts 32, the support | pillar 31b which supports the 2nd coupling | bond part 50, the 2nd coupling | bond part 50, and 2nd. It can be disassembled early except for the barrier plate 20 coupled to the coupling portion 50, and the labor and cost required for construction can be further reduced.

[Modifications to Embodiment]
Although the embodiments of the present invention have been described above, the specific configuration and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can do. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above contents, and may vary depending on the implementation environment and details of the configuration of the invention. May be solved, or only some of the effects described above may be achieved. For example, when the temporary structure 10 for slab formation according to the present embodiment cannot improve the diversion efficiency of the foundation means, when safe and easy construction is not possible, labor and time can be reduced. Even if it is not, when the construction of the slab-forming temporary structure 10 can be prevented by a technique different from the conventional technique, the problem of the present invention is solved.
