Description

  The present invention provides a support support tool improved so as to be able to give a strong independence to a support work composed of a pipe support for supporting a slab formwork, and workability using the support tool. The present invention relates to an improved support assembly method.

In order to support the slab formwork, a support work composed of a pipe support or the like has been widely used. Since this support is not self-supporting itself, for example, there is a method of holding the support works so as not to tilt by connecting the support works vertically and horizontally by changing the height with horizontal connecting materials such as single pipes. It was taken. However, the work to connect vertically and horizontally with this horizontal connecting material is not self-supporting, so an operator who supports the standing state of the support work is also required, which is very troublesome work. Had a big problem. In addition, there is another problem that the horizontal connecting members installed in the vertical and horizontal directions obstruct the worker's walking and other work. Therefore, by using a wall form installed in the lower peripheral part of the slab form, and by connecting the horizontal end thick material installed outside the wall form to the support work, the support work is provided with independence. And the prior art which tries to exclude the horizontal connection material installed vertically and horizontally is also disclosed (refer patent document 1). However, in this prior art, when connecting the horizontal end thick material installed outside the wall formwork and the support work, the gap between the horizontal end thick material and the support work is determined according to the standing position of the support work. As a means for adjusting the length of the connecting tool, a technical means is adopted in which the connecting tool is constituted by a screw member and the length is adjusted by changing the screwing position with the female screw portion on the clamp side. The resistance force that prevents the clamp connector from rotating about its axis was extremely small, and the support work itself was also weak.

  The present invention has been developed in view of the above-described state of the art, and the length can be easily adjusted according to the standing position of the support work, and it is also strong self-supporting with respect to the support work. To provide a supportive support tool that is easy to use and can improve the workability, and to improve the workability of the support work for the slab formwork using the supporter support tool. With the goal.

  In the present invention, in order to solve the above-described problem, two support support tools having a sliding portion having a cross-sectional shape other than a circle and fitted coaxially so as to be movable relative to each other only in the axial direction. In the state where rotation around the shaft center is prevented, one side is installed for supporting work and the other is installed on the end of the wall form frame. The technical means is integrally provided with attachment means that can be attached to the temporary member, and at least one shaft body is provided with a fixing means for preventing relative movement between the shaft bodies. One of the shaft bodies is constituted by a screw joint reinforcing bar, and in a state of being fitted so as to be relatively movable inward of the other shaft body, rotation around the shaft center is prevented by the opposed flat portions of the screw joint reinforcing bar. It is also possible to configure. As for the mounting means, one of the pipes is a single pipe clamp and is configured to be attachable to a supporting work made of a pipe through the single pipe clamp, and the other mounting means is made thicker at the lateral end of the wall frame. It may be configured to be attachable to the material, or both may be configured as single pipe clamps for pipes, and the support works composed of pipes may be configured to be connectable via the single pipe clamps.

  Furthermore, the support assembly method which can improve the workability | operativity regarding the assembly work of the support for a slab form using the support support tool is provided. First, in the assembling method for assembling a support for a slab form using a thick side end material installed outside the wall formwork, a large pulling material is fixed to the upper ends of the two separate support works. The first row of gate-type support assembly is raised, and at least two sets of horizontal end thick members installed in the two support works are separated from each other in the vertical direction outside the wall formwork. On the other hand, the other end of each support support tool temporarily fixed at one end with an interval corresponding to the two support works is temporarily fixed, and the horizontal connection between the support works in the horizontal direction. While fixing the material, install an appropriate number of intermediate support members to support the large pulling material from below between the support members and fix them to the horizontal connecting material, and then two spaced support members A second row of gate-type support assemblies comprising a large pulling material fixed to the upper end of the first row of gate-type support assemblies; The second row of gate-type supports is fixed by passing a long horizontal connecting member in the vertical direction at the intermediate height position of the corresponding support work on both sides of the second row of gate-type support assemblies. In addition to fixing the horizontal assembly between the support members of the second row of gate-type support assemblies, the large pulling material is brought into contact between the support members from below. Install an appropriate number of intermediate support works to support and fix to the horizontal connecting material, and a long horizontal length in the middle height position between the corresponding intermediate support works in the first row and the second row respectively The connecting material is handed over and fixed, and then the next-stage gate-type support assembly, in which the large pulling material is fixed to the upper ends of the two separate support members, is raised. The work is self-supported by fixing it to a long horizontal connecting member in the longitudinal direction protruding from the support work on both sides of the front row, and the support A horizontal connecting member in the horizontal direction is fixed between the works, and an appropriate number of intermediate supporting members are installed between the supporting members to support the large pulling material from below and fixed to the horizontal connecting member, and Assembling the slab form support after assembling the slab formwork after the work of fixing the intermediate support to the vertical horizontal connecting member protruding from the intermediate support in the front row is sequentially repeated. The method was adopted.

  In addition, in the assembly method for assembling the support for the slab form by using the support for the beam erected at the lower part of the beam formwork, a large pulling material is fixed to the upper ends of the two separate support works. The first row of column-type support assembly is raised, and the two support works are spaced apart in the height direction with respect to the beam support work standing at the bottom of the beam formwork. The other end of each support support tool temporarily fixed at one position at an open position is temporarily fixed to be self-supporting, and a horizontal horizontal connecting member is fixed between the support works, and the support work is also performed. Install an appropriate number of intermediate supporters to support the large pulling material in contact with the lower side, and fix it to the horizontal connecting member. Next, fix the large pulling material to the upper ends of the two separate supporters. The second row of gate-type support assemblies, and the first row of gate-type support assemblies and that of the second row of gate-type support assemblies The second-row gate-type support assembly is made self-supporting by passing a long horizontal connecting member in the vertical direction at the intermediate height position of the corresponding support works on both sides, and further, A horizontal horizontal connecting member is fixed between the supporting members of the gate-type supporting member assembly, and an appropriate number of intermediate supporting members are installed between the supporting members to support the large pulling material from below. Fixed to the connecting material, and fixed by passing a long horizontal connecting material in the longitudinal direction at the intermediate height position between the corresponding intermediate supports in the first row and the second row, and then separated. The next-stage gate-type support assembly, in which a large pulling material is fixed to the upper ends of the two support works, is started, and these two support works are projected from the support works on both sides of the front line. By fixing it to the long horizontal connecting material in the direction, and further fix the horizontal connecting material in the horizontal direction between the support works Both of them are fixed to the horizontal connecting member by supporting an appropriate number of intermediate supports between the support members from below and supported, and the intermediate supports are connected to the intermediate supports in the front row. The assembling method of removing the support support tool after assembling the support for the slab formwork by sequentially repeating the work of fixing to the protruding vertical horizontal connecting member was adopted.

  The support support tool according to the present invention has at least a sliding portion having a cross-sectional shape other than a circle, and is composed of two shaft bodies fitted coaxially so as to be relatively movable relative to each other only in the axial direction. At the outer end of these shafts, one can be attached to a supporting work while the other is attached to a temporary member that has already been installed, such as a thicker horizontal end of a wall formwork, in a state where rotation around the axis is blocked Since the mounting means are integrated, rotation around the axis is prevented by the sliding part having a cross-sectional shape other than a circle, and relative movement is possible only in the axial direction. In addition to being able to adjust the standing position of the work, it is possible to provide a support work support tool that is very easy to use because it is possible to ensure a strong independence of the work. In particular, when one of the shaft bodies is composed of a screw rebar, and is fitted so as to be relatively movable inward of the other shaft body, rotation around the axis is prevented by the opposing flat portion of the screw joint rebar. If constituted so, one shaft body which consists of a non-circular cross section can be formed simply and cheaply using a commercially available screw joint reinforcing bar. Furthermore, relative movement can be easily and accurately prevented by using the male thread portion of the threaded reinforcing bar.

  According to the assembling method according to the present invention, a horizontal support material installed outside the wall formwork or a beam support installed upright at the lower part of the beam formwork, which is a temporary member already installed, is used. Secure the independence of the support structures on both sides of the first row of portal support assemblies being assembled, and then connect the second and subsequent column support assemblies vertically and horizontally. Since the assembly method of assembling sequentially while securing independence by connecting to the first row of gate-type support assembly using the material, the standing state of the gate-type support assembly of each row This eliminates the need for support, so that it is possible to reduce the number of workers required in the past and to obtain an accurate standing state of the gate-type support construction assembly, thereby greatly improving the workability. In addition, after the gate-type support assembly of each row is erected in sequence and the assembly of the support for the slab form is finished, the side wall thicker or beam support work of the wall formwork and the first row The support support tool that had been connected to the gate-type support assembly was removed, so there was an obstacle between each support for the slab formwork and the support for the wall formwork or beam. In addition to being effective as an operator's passage, it is extremely effective as a work space for facilitating precise filling by lightly striking the outer surface of the wall formwork when placing concrete for walls. is there.

  The support support tool according to the present invention is generally made of metal, but may be formed of another material having sufficient strength. As the cross-sectional shape of the sliding portion constituting the support support tool, if the cross-sectional shape other than a circle that can prevent relative rotation around the axis between shaft bodies such as a rectangular shape or an elliptical shape, Appropriate cross-sectional shapes can be applied. In particular, it is effective in reducing costs if a threaded bar that is easily available as one of the shafts is employed and a cross-sectional shape having a flat portion on the opposite surface is utilized. Moreover, it is also possible to simply obtain a strong fixed state by configuring the fixing means to be locked to the male thread portion of the threaded reinforcing bar. As a member on the other side for ensuring the self-supporting property of the support, a temporary member that has already been installed, such as a wall end frame thick member or a beam support, is suitable. With respect to the means for attaching to these mating members, a double tube clamp or a U-shaped member that can be sandwiched simultaneously as a set of two horizontal end thick members of the wall form as exemplified in the following examples and for retaining These are used in combination with other wedges, and single tube clamps that can be attached to beam supports made of pipes. In addition, as for the attachment means to the other purpose of the support work, since a support work made of a pipe is common, a single pipe clamp is usually used. Further, as a method of assembling the support for the slab formwork, as described in detail in the following examples, first, using the support support tool, the thickening or beam of the horizontal end of the temporarily installed wall formwork The support structure of the first row of gate-type support assemblies is connected to ensure the independence of the first-column support structure. An assembly method was adopted in which the gate-type support assembly in each row was erected in sequence while using vertical and horizontal horizontal connection materials for the support assembly.

  FIG. 1 is an explanatory view showing an application example of the present invention. In the figure, reference numeral 1 denotes a wall formwork. On the outside of the wall formwork 1, reinforcing horizontal end thick members 4 and 5 are provided in pairs in contact with the vertical frame parts 2 and 3 respectively. A plurality of devices are installed with predetermined intervals in the height direction through the separator 6. In the figure, reference numeral 7 denotes a support support tool according to the present invention. One outer end is attached to the horizontal end thick member 4 and the other outer end is attached to the support member 8, respectively. By connecting 4 and the support work 8, the support work 8 is provided with independence. 2 to 4 show the assembled state of the first embodiment relating to the supporter support tool, FIG. 2 is a front view thereof, FIG. 3 is a longitudinal sectional view, and FIG. 4 is a plan view thereof. is there. In particular, as shown in the longitudinal sectional view of FIG. 3, the support support tool 7 according to this embodiment includes a hollow first shaft body 10 in which a single tube clamp 9 is fixed to an outer end portion by welding or the like. The second shaft body 12 is inserted into the first shaft body 10 and has a double-tube clamp 11 fixed to the outer end thereof by welding or the like. Then, as shown in FIG. 5, the distance between the single tube clamp 9 and the double tube clamp 11 at both ends is adjusted by relatively moving the first shaft body 10 and the second shaft body 12 in the axial direction. be able to.

  FIG. 6 is a cross-sectional view taken along the line AA indicated in FIG. 3, and shows an enlarged cross-section at the sliding portion between the first shaft body 10 and the second shaft body 12. FIGS. 7 to 11 show each part constituting the support support tool 7. As shown in FIGS. 7 and 8, the first shaft body 10 in the present embodiment is formed in a hollow shape having a circular cross section as a whole, and crushes the end opposite to the single tube clamp 9 in parallel. Thus, a flat sliding portion 13 is formed as shown in FIG. In this case, as shown in FIG. 8, the planar outer dimension of the sliding portion 13 is also slightly reduced. Further, as shown in the BB cross-sectional views of FIGS. 7 and 9, a nut 14 is welded in the vicinity of the sliding portion 13 on the outer peripheral portion of the first shaft body 10. The tightening and fixing bolt 15 constitutes a fixing means for preventing relative movement between the shaft bodies 10 and 12. In addition, openings 16 and 17 for retaining, which will be described later, are formed on the outer peripheral portion of the first shaft body 10 that is closer to the single tube clamp 9 side. These openings 16 and 17 also function as escape holes for the liquid remaining in the first shaft body 10. Incidentally, the single pipe clamp 9 opens an opening / closing member 19 pivotally attached to a support shaft 18 and is fitted on the support 8, and then the opening / closing member 19 is closed and screwed into a bolt 20 via a nut 21. To fix the support work 8.

  As shown in FIG. 10, the 2nd shaft body 12 in a present Example is provided with the double tube clamp 11 in an outer end part as mentioned above. Incidentally, the other shaft end portion 22 of the second shaft body 12 is inserted into the hollow portion of the first shaft body 10 as will be described later, and then crushed by a punch or the like to be processed for retaining. . The double tube clamp 11 is externally fitted to a first clamping member 23 fixed to the outer end portion of the second shaft body 12 by welding or the like, and a male screw portion 24 formed on the second shaft body 12. The second clamping member 26 is configured to be tightened from the outside by a nut 25 screwed into the male screw portion 24. And as shown in CC sectional drawing of FIG. 11, as for the 2nd shaft body 12, parts other than the external thread part 24 for the double tube clamp 11 are formed in the flat cross-sectional shape.

  Thus, when the second shaft body 12 is inserted through the opening of the sliding portion 13 of the first shaft body 10, the support work support tool 7 shown in FIGS. 2 to 4 is formed. In this case, as shown in FIG. 6, the first shaft body 10 and the second shaft body 12 are related to the flat sliding portion 13 of the first shaft body 10 and the flat second shaft body 12. As a result, rotation about the axis is prevented, and only relative movement in the axial direction is allowed. Therefore, one outer end portion of the support support tool 7 is attached to the thick side material 4 via the double tube clamp 11, and the other outer end portion is attached to the support work 8 via the single tube clamp 9. If the horizontal end thick material 4 and the support work 8 are connected to each other, the support work 8 is provided with strong independence. After inserting the second shaft body 12 into the first shaft body 10, a tool such as a punch is inserted through the openings 16 and 17 formed in the first shaft body 10, and the second shaft By crushing and deforming the shaft end portion 22 of the body 12, a retaining portion 27 having a size larger than the opening width of the sliding portion 13 is formed as shown in FIG. 12. In the figure, reference numeral 28 denotes a lower opening formed when the insertion hole of the bolt 15 is drilled.

  FIGS. 13 to 16 are enlarged views of the main part in the assembled state of the second embodiment relating to the support support tool, FIG. 13 is a partially enlarged front view, FIG. 14 is a partially enlarged plan view, and FIG. Is a longitudinal sectional view of FIG. 13, and FIG. 16 is a longitudinal sectional view of FIG. 17 is a cross-sectional view taken along the line DD indicated in FIG. 13, and FIG. 18 is a cross-sectional view taken along the line EE shown in FIG. The support support tool 29 according to the present embodiment is characterized in that a second shaft body 30 made of screw joints is used in place of the second shaft body 12, and the remaining structure is the same as that described above. Since there is no fundamental difference from the first embodiment, the same components are denoted by the same reference numerals and description thereof is omitted. Accordingly, since the second shaft body 30 of the support member 29 according to the present embodiment employs the screw joint reinforcing bar, as shown in FIG. 14, the opposed flat portions 31 formed over the entire length of the screw joint reinforcing bar. 17 is engaged with the sliding portion 13 of the first shaft body 10 shown in FIG. 17 to prevent rotation around the axis and allow only relative movement in the axial direction. . Therefore, as in the case of the first embodiment described above, if the horizontal end thick material 4 of the wall mold 1 and the supporter 8 are connected by the supporter support tool 29, the supporter 8 has a strong independence. Can be granted. It is also possible to fasten and fix the second clamping member 26 of the double-pipe clamp 11 by screwing the nut 25 using the male thread portion of the screw rebar. In addition, since a commercially available threaded bar can be used, it is very easy to obtain the material, which is very effective for cost reduction. Incidentally, it is also possible to easily obtain a strong fixed state if the fixing means is configured to be locked to the male thread portion of the threaded reinforcing bar instead of the present embodiment.

  19 and 20 show the assembled state of the third embodiment relating to the support support tool, FIG. 19 is a front view thereof, and FIG. 20 is a plan view thereof. The support support tool 32 according to the present embodiment includes a combination of a U-shaped member 33 and a retaining wedge 34 instead of the double tube clamp 11 provided at the outer end portion of the second shaft body 12. Since there is a feature in that the mounting means 35 is employed, and the remaining configuration is basically different from the first embodiment, the same components are denoted by the same reference numerals for description. Omitted. Thus, in the case of the attachment means 35 of the support support tool 32 according to this embodiment, the U-shaped member 33 fixed to the outer end portion of the second shaft body 36 formed in a flat shape by welding or the like. In the same manner as in the first embodiment, it is externally fitted to the horizontal end thick material 4 and the like through the open portion of the wall, and then formed on the upper and lower plate-like portions of the U-shaped member 33. By inserting the wedge 34 for preventing slippage through the insertion hole 37, it is possible to fix the lateral end thick material 4 and the like in a state in which rotation around the axis is prevented. Therefore, as in the case of the first embodiment described above, if the horizontal end thick member 4 of the wall mold 1 and the supporter 8 are connected by the supporter support tool 32, the supporter 8 has strong independence. Can be granted. In this embodiment, as shown in FIG. 20, the insertion holes 37 are formed in the upper and lower plate-like portions of the U-shaped member 33 by changing the front and rear positions of the insertion holes 37, so The insertion position of the wedge 34 can be adjusted according to the dimensions. In the figure, reference numeral 39 denotes a string-like member for preventing the wedge 34 from being lost.

  FIGS. 21 and 22 show the assembled state of the fourth embodiment relating to the support support tool, FIG. 21 is a front view thereof, and FIG. 22 is a plan view thereof. The support support tool 40 according to the present embodiment is characterized in that a single tube clamp 41 similar to the single tube clamp 9 is employed instead of the double tube clamp 11 provided at the outer end portion of the second shaft body 12. In other configurations, there is no fundamental difference from the first embodiment, and therefore, the same components are denoted by the same reference numerals and description thereof is omitted. Thus, in the case of the support support tool 40 according to the present embodiment, one single tube clamp 9 is attached to the support 8 and the other single tube clamp 41 is erected at the lower part of the beam formwork. By attaching to a support for a pipe-shaped beam (not shown) or to another support that has already been installed, as with the case of the lateral end material 4 of the wall formwork 1, both of them are prevented from rotating around the axis. It can be connected in the state which was made, and strong independence can be provided with respect to the support work 8. FIG. Incidentally, it goes without saying that the form adopting the single pipe clamp as the attachment means on both sides can be applied to the second embodiment in which the threaded reinforcing bar is used as the second shaft body. Further, in the first to fourth embodiments described above, the first shaft body and the second shaft body are interchanged, the second shaft body is formed in a hollow shape, and the first shaft body is inserted into the inside thereof. It is also possible to configure as described above.

  Next, the assembling method of the support for the slab formwork will be described using the support support tool according to the present invention. FIG. 23 is a construction state diagram showing a state in which the first-column portal support assembly is installed in the first embodiment relating to the support assembly method. As shown in the figure, in the support assembly method according to the present embodiment, first, the two support works 8 made of pipes are used, and in the state where the support works 8 are laid horizontally, the outer sides of both support works 8 are shown. The large pulling material 42 is fixed to the upper ends of the support members 8 spaced apart from each other with a predetermined space between the surrounding construction members and a passage or work space. Thus, the gate-type support assembly 43 in the first row is formed. In addition, the height adjustment of the large pulling material 42 is performed via a connection adjustment unit 45 disposed in a connection portion between the support work 8 and the upper support work part 44 as necessary. Thereafter, as shown in the figure, the first-stage gate-type support assembly 43 assembled in a horizontal state is raised, and the support works 8 on both sides of the gate-type support assembly 43 are formed in the wall form as previously described with reference to FIG. 1 is held through a single tube clamp 9 at the other end of two upper and lower support support tools 7 attached to a thick horizontal end member 4 having different heights, which are installed outside 1, via a double tube clamp 11. Thereby, the self-supporting property of the support work 8 on both sides of the gate-type support assembly 43 is ensured, and the standing state of the gate-type support work assembly 43 in the first row is maintained.

  When the standing state of the gate-type support assembly 43 in the first row is maintained as described above, the horizontal connecting members in the horizontal direction are further fixed between the support works 8 on both sides, and those An appropriate number of intermediate support members are installed between the support members to support the large drawing material from below and fixed to the horizontal connecting member. Thereafter, the second row of gate-type supports, in which a large pulling material is fixed to the upper ends of two spaced-apart support members assembled in a horizontal state in the same manner as the first row of gate-type support assemblies 43. The vertical assembly is raised to the middle height position of the corresponding two-sided support structure of the first row of gate-type support assemblies 43 and the second-column support structure of the second row. The gate-type support assembly in the second row is made independent by passing and fixing the long horizontal connecting member. In addition, a horizontal horizontal connecting member is fixed between the support members of the second-stage gate-type support assembly, and an appropriate number of intermediate supports are supported by supporting the large pulling material from below between the support members. A work is installed and fixed to the horizontal connecting member. Furthermore, a long horizontal connecting member in the vertical direction is also passed and fixed to the intermediate height position between the corresponding intermediate supports in the first row and the second row. As a result, the gate support structure 43 in the first row and the gate support assembly in the second row (not shown) are self-supporting, and support on both sides of the gate support assembly in the second row is also provided. From the intermediate height position of the work and the intermediate height position of each intermediate support work, a long horizontal connecting material in the vertical direction is extended.

  After that, the next-stage gate-type support work in which a large pulling material is fixed to the upper ends of two spaced-apart support works assembled in a horizontal state in the same manner as the first-type gate-type support work assembly 43. The assembly is raised, and the two support works are fixed independently by fixing them to the long horizontal connecting members in the vertical direction protruding from the support works on both sides of the front row. By the way, when starting the next-stage gate-type support assembly, the large pulling material extends below the long vertical horizontal connecting member extending from the second-column support structure. When positioned, the large pulling material is moved upward through a space ahead of the tip of the horizontal connecting member. In addition, a horizontal horizontal connecting member is fixed between the support members, and an appropriate number of intermediate support members are installed between the support members to support the large pulling material from below and fixed to the horizontal connecting member. And the operation | work which fixes those intermediate support works to the vertical horizontal connection material protruded from the intermediate support work of the front row is repeated sequentially, and the support work for the said slab formwork is assembled. Then, by removing the support support tool 7 after the assembly is completed, a passage and a work space are formed around the support assembly for the slab formwork. After that, a plywood 47 is installed on the upper part of each large pulling material 42 fixed to the upper end of each supporting work 8 through a joist 46 made of a pipe or the like as necessary, and concrete for slab is placed on the upper part. Will be cast.

  Furthermore, as a second embodiment related to the support assembly method, the wall mold 1 adopted in the first embodiment related to the assembly method in order to ensure the self-supporting property of the first-stage gate-type support assembly. A slab formwork support assembling method using a beam support work composed of a pipe standing upright at the lower part of the beam formwork is also possible instead of the horizontal end thick material 4 installed outside the slab. The support assembly method according to the second embodiment uses the support support tool 40 provided with single tube clamps 9 and 41 at both ends, and is attached to the beam support through one single tube clamp 41. By attaching to the supporters on both sides of the first row of gate-type support assemblies through the other single pipe clamp 9, the self-supporting property of the first-row portal support assembly is ensured. Has characteristics. The assembly method after the self-supporting of the gate-type support assembly in the first row is the same as in the case of the first embodiment and has the same operational effects.
