Abstract

PROBLEM TO BE SOLVED: To provide a form transfer device which has superior versatility and transportability.SOLUTION: A rail member 5 of a form transfer device 1 is formed of a pair of rails 5a and a plurality of crosspiece materials 5b bridged between the pair of rails 5a. Therefore, even in the state where the rail member 5 is placed on an erection member 4, a top face 4a of the plate-like erection member 4 is exposed in a portion in which there is no crosspiece material 5b. A worker C can thus move or work while standing on the erection member 4 that can be used as a gangboard. Thus, the form transfer device 1 has superior versatility. Leg members 2 and 3, the erection member 4 and the rail member 5 are all separate members so that each member is not bulky in comparison with the case where the device is integrated as a whole. Accordingly, the form transfer device 1 also has superior transportability and storage capability.

Description

  The present invention particularly relates to a formwork transfer device for transferring formwork at a construction site.

  Conventionally, a reusable steel formwork has been used in the construction of foundations for construction sites such as houses. When used at a construction site, it is common for a road plate to be bridged on a reinforcing bar that rises in a lattice shape, and an operator manually transports a steel formwork using this road plate. However, in such a method, (1) it takes a lot of labor for hand transportation, (2) there is a risk that the road plate will be bent and drop the steel formwork, or the operator may fall down, (3) There was a problem that rework may occur due to the movement and inclination of the reinforcing bars.

  Then, as described in the following Patent Document 1, a formwork transfer device for transferring a formwork at a construction site has been proposed. This device includes a frame supported by legs. The frame has a roller conveyor in which a large number of rollers are attached to a shaft. The roller conveyor is installed horizontally in the width direction and inclined in the length direction. The worker at the construction site moves the formwork by the inclination by placing the formwork on the roller conveyor and pushing it.

  In this apparatus, a support member is fixed to the lower surface of the end portion of the frame body, and a leg is attached to the support member via an attachment fitting or the like. The legs can be lowered. Moreover, the length of the leg can be adjusted by expansion and contraction, and the roller conveyor can be installed on the inclined ground. When transporting or storing the device, the legs are folded along the frame.

Japanese Utility Model Publication No. 61-101510

  However, in the above-described conventional apparatus, since the rollers are arranged on almost the entire surface of the frame body, it can be used only for transporting the formwork and lacks versatility. Moreover, although a leg is foldable, a frame and a leg are bulky and its conveyance property is bad. Thus, improvement in versatility and transportability is a problem in the formwork transfer device.

  An object of the present invention is to provide a formwork transfer device excellent in versatility and transportability.

  The formwork transfer device of the present invention includes a plurality of leg members, a long plate-like installation member that is supported by being supported by the plurality of leg members, a pair of rails having sliding portions formed on the upper surface, A rail member that is bridged between the pair of rails and is formed of a plurality of crosspieces that keep the pair of rails parallel to each other.

  According to this formwork transfer device, the rail member is placed on the erection member, and the formwork can be moved by placing the formwork on the sliding portion formed on the upper surface of the rail of the rail member. Here, since the rail member is composed of a pair of rails and a plurality of crosspieces spanned between the pair of rails, even in a state where the rail member is placed on the installation member, The plate-shaped erection member is exposed. Therefore, the worker can stand on the construction member and move or work. That is, the installation member can be used as a road plate. Further, since the rail member is a separate member, the installation member can be used as a road plate by removing the rail member. Further, when the curing of the concrete is completed and the loose formwork is carried out, only the rail member can be bridged and used on the upper surface of the completed cloth foundation. Thus, the formwork transfer device of the present invention is excellent in versatility. Further, since the leg member, the erection member, and the rail member are separate bodies, each member is not bulky as compared with the case where the entire apparatus is integrated. Therefore, the formwork transfer device of the present invention is excellent in transportability.

  Moreover, in the said formwork transfer apparatus, the width | variety of a construction member is smaller than the separation distance of a pair of rail, and a some crosspiece is mounted on a construction member. According to this configuration, the distance between the pair of rails can be sufficiently secured while using a narrow erection member, and stability during the transfer of the formwork is maintained. Further, since the plurality of crosspieces are supported by the erection member, the crosspieces for keeping the pair of rails in parallel can be used effectively.

  Moreover, in the said formwork transfer apparatus, a rail member is foldable, when a rail and a crosspiece are hinge-joined. According to this configuration, the transportability of the formwork transfer device is further enhanced. Moreover, it is excellent also in storage property.

  ADVANTAGE OF THE INVENTION According to this invention, the form transfer apparatus excellent in versatility and transportability can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1 and FIG. 2, the formwork transfer device 1 is a device that is installed in a construction site such as a house and transfers a formwork for foundation construction within the site. The formwork transferred by the formwork transfer device 1 is, for example, a reusable steel formwork D (see FIG. 7). The formwork transfer device 1 is placed on a plurality of leg members 2, 3, a long plate-like erection member 4 that is supported by being supported by the plurality of leg members 2, 3, and the erection member 4. The rail member 5 is provided.

  The leg members 2 and 3 are for supporting the long plate-like erection member 4. Each of the leg members 2 and 3 is erected on the root cutting surface A or the island (banking formed by temporarily placing the residual soil generated by the root cutting) where the foundation is constructed. The leg members 2 and 3 are arranged in a substantially straight line with a predetermined interval. The leg member 2 is a leg member for installing a root cut surface, and the leg member 3 is a leg member for installing an island.

  The leg member 2 for root cutting surface installation includes a receiving plate portion 10 that supports the erection member 4, a bottom plate portion 11 that is installed on the root cutting surface A, and a shaft portion that connects the receiving plate portion 10 and the bottom plate portion 11. 12A. In the vicinity of the corner portion of the upper surface 10 a of the rectangular receiving plate portion 10, a displacement preventing piece 16 that prevents the erection member 4 from being displaced is projected.

  As shown in FIGS. 3A to 3C, for example, three types of leg members 2A, 2B, and 2C are prepared as the root member 2 for installing the root cut surface. The leg members 2A, 2B, and 2C are prepared in accordance with the depth of the root cutting surface A set in stages, that is, the bottom surfaces of the foundations 20, 21, and 22, respectively. In the leg members 2A, 2B, and 2C, the receiving plate portion 10 and the bottom plate portion 11 are made common, and only the shaft portions 12A, 12B, and 12C are different. The lengths of the shaft portions 12A, 12B, and 12C are set stepwise according to the depth of the root cut surface A. That is, the lengths of the shaft portions 12A, 12B, and 12C differ by the level difference ΔH of the root cut surface A. The lengths of the shaft portions 12A, 12B, and 12C are such that the height of the upper surface 10a of the receiving plate portion 10 is higher than the upper end surfaces 20a, 21a, and 22a of the foundations 20, 21, and 22 when the leg members 2A, 2B, and 2C are installed. Is set to be higher.

  As shown in FIG. 2 and FIG. 4, the island installation leg member 3 includes a receiving plate portion 10 that supports the erection member 4, a bottom plate portion 11 that is installed on the island B, and the receiving plate portion 10 and the bottom plate. And a shaft portion 13 that connects the portions 11. In the vicinity of the corner portion of the upper surface 10 a of the rectangular receiving plate portion 10, a displacement preventing piece 16 that prevents the erection member 4 from being displaced is projected.

  In the case of the leg member 3, since the height of the island B is not uniform, the length of the shaft portion 13 can be finely adjusted. That is, the height from the bottom surface of the bottom plate portion 11 to the upper surface 10a of the receiving plate portion 10 can be finely adjusted. For example, in the case of the relatively high island B1 (see FIG. 4), the shaft portion 13 is contracted to reduce the overall height of the leg member 3, and in the case of the relatively low island B2, the shaft portion 13 is extended to extend the leg. The height of the entire member 3 can be increased.

  As shown in FIG. 1 and FIG. 2, the erection member 4 is for mounting and supporting the rail member 5. The erection member 4 can also be used as a road plate. In other words, a commonly used road plate can be used as the erection member 4. The erection member 4 is made of, for example, steel, aluminum, or plywood. A plurality of erection members 4 are juxtaposed in the longitudinal direction according to the distance to which the mold D is transferred. Both ends of the erection member 4 are placed and supported on the upper surface 10a of the receiving member 10 of the leg member 2 or the leg member 3. That is, the leg members 2 and 3 are arranged in the continuous portion of the erection member 4 and are configured to support the end edges of the two erection members 4 simultaneously. In addition, the erection member 4 may be mounted only on the leg member 2 or the receiving plate portion 10 of the leg member 3, or may be connected by a connecting metal fitting. Further, the plurality of erection members 4 may be connected to each other.

  The rail member 5 is composed of a pair of rails 5a and 5a having a sliding portion 5c formed on the upper surface, and two bars that are bridged between the pair of rails 5a and 5a and keep the pair of rails 5a and 5a in parallel. And a material 5b. The rail member 5 is configured in a ladder shape when in use. The sliding portion 5c is composed of a plurality of rollers (or rollers) 17 arranged in a straight line with both ends of the shaft fixed to a pair of long support plate members arranged so as to face each other. .

  The crosspiece 5b is fixed to the lower end surface of the rail 5a by a bolt 25 (see FIG. 6). By loosening the bolt 25, the bolt 25 serves as a hinge, and the rail member 5 can be folded compactly. That is, the rail 5a and the crosspiece 5b are hinge-joined. A connection fitting 18 for connecting the rail members 5 to each other is provided at the end of the rail member 5. The connecting metal fitting 18 is rotatably attached to the rail 5a of one rail member 5 and is hooked on a protrusion 19 provided on the rail 5a of the other rail member 5.

  Here, the length of the crosspiece 5 b is longer than the width of the erection member 4. That is, the width of the erection member 4 is smaller than the distance between the pair of rails 5a and 5a. Therefore, the crosspiece 5 b is placed on the upper surface 4 a of the erection member 4, and the rail 5 a protrudes on both sides of the erection member 4. In a state where the rail member 5 is placed on the erection member 4, the upper surface 4a of the erection member 4 is exposed at a portion where the crosspiece 5b is not present. Thereby, the worker can stand on the erection member 4 and move or work.

  With reference to FIG. 5 and FIG. 6, the work procedure using the formwork transfer apparatus 1 will be described. First, proceed with the foundation work in the normal procedure. In other words, root cutting, groundwork, bar arrangement, etc. are performed. Next, as shown in FIG. 5A, the leg members 2 and 3 are erected at predetermined positions. When installing on the root cutting surface A, the leg member 2 for root cutting surface installation is used. In this case, a shaft portion (any one of the shaft portions 12A, 12B, and 12C) corresponding to the depth of the root cut surface A is selected. When installing on the island B, the height is finely adjusted by expanding and contracting the shaft portion 13 using the leg member 3 for installing the island.

  Next, as shown in FIG. 5B, the erection member 4 is placed on the upper surface 10 a of the receiving plate portion 10 of the leg members 2 and 3. Here, the erection member 4 is arranged between the stopper pieces 16 and 16 projecting from the receiving plate portion 10. Next, the rail member 5 is folded (see FIGS. 5C and 6A) to a ladder-like use state (see FIG. 6B), and the bolts 25 are tightened.

  Next, the rail member 5 is placed on the erection member 4 and connected by the connecting metal fitting 18. The mold transfer apparatus 1 shown in FIG. 1 is completed by the series of operations described above.

  Then, as shown in FIG. 7, when the worker C places and pushes the steel mold D on the rail member 5, the mold D is transferred. Another worker (not shown) lowers the transferred form D and stands at a predetermined position. After the mold D is installed at a predetermined position, concrete is cast and cured for a certain period. Finally, release the formwork.

  According to the formwork transfer apparatus 1 of the present embodiment, the rail member 5 is placed on the erection member 4, and the formwork D is placed on the sliding portion 5c formed on the upper surface of the rail 5a. Can be moved. Since the rail member 5 includes a pair of rails 5a and a plurality of crosspieces 5b spanned between the pair of rails 5a, there is no crosspiece 5b even when the rail member 5 is placed on the installation member 4. In the portion, the upper surface 4a of the plate-like erection member 4 is exposed. Therefore, the worker C can stand on the erection member 4 to move or work, and the erection member 4 can be used as a road plate. Moreover, since the rail member 5 is a separate body, the construction member 4 can be used as a road plate by removing the rail member 5. In addition, when the concrete curing is finished and the loose formwork D is carried out, only the rail member 5 is bridged over the upper surfaces 20a, 21a, and 22a of the finished fabric foundations 20, 21, and 22 (see FIG. 3). Can also be used. Further, the erection member 4 and the rail member 5 may be bridged between the upper end surfaces 20a, 21a, and 22a of the completed fabric foundations 20, 21, and 22. Thus, the formwork transfer apparatus 1 is excellent in versatility. Moreover, since the leg members 2 and 3, the erection member 4, and the rail member 5 are separate bodies, each member is not bulky as compared with the case where the entire apparatus is integrated. Therefore, the form transfer device 1 is excellent in transportability and storage property.

  Moreover, since the width of the erection member 4 is smaller than the distance between the pair of rails 5a and 5a, and the plurality of crosspieces 5b are placed on the upper surface 4a of the erection member 4, the erection member 4 having a narrow width is used. However, a sufficient distance between the pair of rails 5a can be secured, and stability during the transfer of the mold D is maintained. Further, since the plurality of crosspieces 5b are directly supported by the erection member 4, the crosspieces 5b for keeping the pair of rails 5a in parallel can be effectively used.

  Moreover, since the rail 5a and the crosspiece 5b are hinge-joined and the rail member 5 is foldable, the transportability of the formwork transfer apparatus 1 is further enhanced. Moreover, the rail member 5 is excellent also in storage property.

  Moreover, since the leg members 2 and 3 are arranged in the connecting portion of the erection member 4 and are configured to support the edge portions of the two erection members 4 at the same time, steps and unevenness of the linking portion are prevented. The formwork D can be smoothly transferred.

  In the formwork transfer device 1, the strength and stability of the leg members 2 and 3 are sufficiently ensured so that the construction member 4 can be operated while the rail member 5 is placed or the rail member 5 is removed. Can be used for moving. Normally, when placing concrete, a road plate is laid over the formwork D. Therefore, the position and height of the formwork D may change and may need to be corrected. Since the apparatus 1 does not span the mold D, the accuracy of the mold D is maintained.

  In addition, after curing concrete for a certain period, the formwork D is loosened, and when the concrete form D is unloaded, it can be transferred in the same procedure. In this case, without using the leg members 2, 3, the erection member 4 is laid over the upper end surfaces 20 a, 21 a, 22 a of the foundations 20, 21, 22, and the rail member 5 is placed on the erection member 4 and used. Also good. In addition, the rail member 5 does not need to prepare for the full length of the installation member 4, For example, the transfer of the formwork D is also possible by feeding the two rail members 5 forward. In this way, the number of rail members 5 to be prepared can be minimized.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment. For example, the width of the erection member 4 may be larger than the separation distance between the pair of rails 5a and 5a. The crosspiece 5b is not limited to the case where two are provided for the pair of rails 5a and 5a, and may be three or more.
