[Prior art]

 A conventional formwork support device, in which vertical end thick materials and horizontal end thick materials that support beam side formwork are tightly fixed using formwork clamps such as separators and foam ties, has a large number of parts・ Because the disassembling method is also complicated, a form supporting device has been proposed in the past, in which a vertical end thick member that directly supports the beam side form is movably connected to and supported by a hauling member.

As such a frame support device, for example, Japanese Utility Model Laid-Open No. 1-98858 is known. As shown in FIG. 7, this conventional frame support device has side support members 102 and center support members 103. The horizontal members 104 and the diagonal members 105 were connected to each other to form the support 101 in one frame. At the upper end of the center support member 103, a horizontal support plate 107 for supporting the beam bottom form 106 is installed, and a pair of left and right pulling members 108, 108 are connected to both ends thereof so as to be vertically swingable. Was there.

The pulling bar 108 is horizontally supported by the side supporting members 102, and a support metal fitting 109 having a substantially U-shaped cross section is slidably fitted on the upper surface of each pulling bar 108. Vertical end thick members 111 for supporting the beam side form 110 were vertically provided at opposite ends of the support fitting 109. In this conventional formwork support device, the support 101 supports the vertical and lateral loads of the beam 112, but the floorform formwork 114 of the floorboard 113 adjacent to the beam 112 stands upright from the lower floorboard 115. It was supported separately by supporting works such as the pipe support 116 to be installed.

By the way, if the support work for the slab formwork 114 is set up as described above, the work on the lower slab 115 becomes extremely difficult. Therefore, a method of supporting the slab formwork 114 with support beams is required. is there. This support beam receives the intermediate load as a beam only by supporting both ends, and supported both ends by pipe supports.

[0006]

[Problems to be solved by the device]

 However, the pipe support that supports the supporting beams needs to be erected as close as possible to the side faces of the beams, which has the drawback that the building work is troublesome. Further, since the conventional form supporting device does not have a member for independently supporting the supporting beam, when the supporting beam is supported without using the pipe support from the lower floor slab 115, the beam side form 1 It was necessary to load the support beam claw fittings on the top of 10. However, the support beam support by the beam side form 110 is unstable, and there is a drawback that the beam frame after the form is disassembled is notched by the claw fitting.

This invention aims at effective utilization of the lower floor slab by receiving the floor slab formwork with the support beam, stably supports the support beam, and facilitates disassembly of the support beam / beam formwork and support work. Moreover, it is an object of the present invention to provide a form supporting device that makes the beam-formed form beautiful.

[0008]

Next, the operation of the frame support device 1 will be described. First, a plurality of rows of the mold support devices 1 are arranged at predetermined positions on the lower floor slab 11 in the transverse direction of the beam 19. A plurality of formwork supporting devices may be connected in advance using a member connecting fitting. An example of this case is shown in FIG. FIG. 5 is a side view of assembling a beam form by connecting a plurality of form supporting devices. The two rows of frame support devices 1, 1 are connected to each other by engaging the casters 10 with the lower member connecting fittings 9 and installing the horizontal connecting members 32. Further, the horizontal connecting member 33 is also engaged with the upper connecting fitting 9, and the brace 34 is bridged between the horizontal connecting members 32, 33 to firmly connect the two rows of form supporting devices 1, 1.

In this way, the beam bottom formwork 12 is placed on the central pulling member 13 on the central supporting frame 6 of each formwork supporting device 1 arranged in the transverse direction of the beam 19. Next, the left and right side pulling members 14, 14 are respectively rotated upward around the pins 13a to be loaded on the jack base 7 of the side strut 2, and the jacks are observed while observing the horizontal side pulling member 14 horizontally. Finely adjust the height with the bases 7 and 17.

On the other hand, a beam side surface form 22 is attached to the vertical end thick material 6 protruding from the support fitting 5, and the fastening bolt 21 is moved in the elongated hole 14a to fix the support fitting 15 at a predetermined position. At this time, the pipe support 18 is located above the side support 2. Next, while adjusting the height of the pipe support 18, the hauling material 31 is placed on the receiving plate 27a. The claw fittings 30a of the supporting beam 30 are suspended on the large pulling material 31, the floor slab formwork 29 is assembled on the supporting beam 30, and connected to the top of the beam side formwork 22. Through the above steps, as shown in Fig. 1, the beam / slab formwork assembly is completed and the preparation for concrete pouring is completed.

A floor slab load at the time of placing concrete is transmitted to the side support 2 through the supporting beam 30, the pulling bar 31, and the pipe support 18. The vertical load of the beam 19 acts on the central support frame 6 via the joists 12 a attached to the beam bottom formwork 12 and the central pulling bar 13, and is transmitted to the side support columns 2 through the diagonal members 5 supporting this. Further, the lateral pressure acting on the beam side form 22 is transmitted to the vertical end thick member 16 through the lateral end thick member 22a. This load is also transmitted to the diagonal member 23 and the horizontal member 24, and acts as a vertical load on the side pull member 14 through the support fitting 15. Furthermore, this load is finally transmitted to the side support 2 as an axial force.

At the time of disassembling the formwork, the jack base 27 on the pipe support 18 is loosened, and the floor slab formwork 29 and the support beams 30 are removed. Next, the side support 2 is contracted to release the support of the side pulling bar 14 and the side pulling bar 14 is rotated downward about the pin 13a, or the support metal fitting 15 is slid to move the side surface of the beam. The form 22 is disassembled. Even in this state, the beam bottom formwork 12 can be continuously cured if the lower jack base 17 is not loosened. Therefore, if the beam side, floor slab, and lower beam curing periods are different, the supporting beam 30 The floor slab form 29 and the beam side face form 22 can be diverted at an early stage.

When the form supporting apparatus 1 is diverted after the entire curing period has passed, the supporting metal fittings 15 are disassembled on the side pulling members 14 without sliding. Fig. 6 shows a front view of the dismantled formwork. With the downward rotation of the side hauling member 14, the beam side form 22, the vertical end thick member 16, and the pipe support 18 rotate to a horizontal state. The outer pipe 18b of the pipe support 18 is supported by the jack base 7 of the side support 2. Next, the lower jack base 17 is loosened, the caster 10 is grounded to the lower floor slab 11, and the jack base 17 is removed. If it is diverted in this state, it is not necessary to slide the beam side form 22 in the case of reassembly, and it can be immediately erected at a predetermined position.
