The present invention relates to a temporary beam support device for slab (Slab) formwork, in particular, by making it easy to adjust the height, not only can easily install the temporary beam, it can be easily and safely dismantled the concrete beam after pouring concrete The present invention relates to a temporary beam support device for slab formwork.

For example, in order to construct a slab that divides the upper and lower layers, first, a slab formwork must be installed at the lower part of the slab construction.

Slab formwork, as shown in Figure 1 is usually made by reinforcement work on the upper portion of the plate material 40, such as slabs or plywood, and by placing and curing the concrete thereon, to form the slab (50).

In the slab construction process as described above, the slab formwork and the slab 50 is supported by the formwork support device by the temporary beam and the copper bar, the joist (30) and yoke (20) is used as the temporary beam, As the furnace, a pipe support 10 is usually used. That is, the joists 30, which mean the horizontal beams, support the lower part of the plate 40 at predetermined intervals, and the yokes 20, which represent the longitudinal beams, support the lower parts of the joists 30 at predetermined intervals, and the yoke ( 20 are to be supported by the pipe supports (10). Then, the construction of the slab formwork is completed by the formwork support device as described above, and after the concrete is poured into the slab formwork, if the slab 50 is cured for a certain required time so as not to collapse, the next layer of slab construction For the purpose of retrieval, the temporary beams 20, 30 of the formwork supporting device should be dismantled and the pipe support 10 should support the slab 50 until the slab 50 is fully cured.

By the way, when the formwork is installed by the conventional formwork supporting device as described above, it is difficult to horizontally install the temporary beams such as the joist 30, the yoke 20, and the like. That is, in general, in the case of the pipe support 10, the height can not be substantially adjusted, and the height of the pipe support 10 may be adjusted by a screw transfer method by a nut. Very hard In addition, since a separate member is further provided on the upper portion of the pipe support 10 so that the height can be adjusted, the work becomes more difficult.

On the other hand, when the temporary beams are installed horizontally and vertically at the same height, the beam beams may not be performed by the above-described method. For example, beam beams may be installed on the main beams, and the beam necks may be installed. (Beam Neck) is used to combine the other beams to be orthogonal, but in this case it is more difficult to support the temporary beams. Of course, the same is true when hypothesis beams are hypothesized.

In the process of disassembling the temporary beams 20 and 30, the temporary beams 20 and 30 must be disassembled while the pipe support 10 is lowered or removed, and the hypothetical beams falling during the disassembly process. Since there is no means for supporting the 20 and 30, the worker may be greatly injured by the falling beams 20 and 30 if the attention is not required.

The present invention has been made in consideration of the above-mentioned conventional problems, and by allowing height adjustment to be easily performed, it is not only easy to install the temporary beam, but also to easily and safely dismantle the temporary beam after concrete placement. .

In order to solve this, it is preferable that the auxiliary support pins 220 are respectively coupled in the orthogonal state to both ends of the support pins 210 protruding out of the support pipes 110 of the support pins 210, respectively. 220 and the bottom of the wing plate 200 may also be welded.

The support pin 210 and the auxiliary support pin 220 may be formed in an inverted trapezoidal shape, for example, according to the inclination of the wing 202. In this case, as shown in Figure 5, the upper coupling grooves 212 are formed on both sides of the upper end of the support pins 210, respectively, the lower coupling grooves 222 in the lower center of the corresponding support pins 220 If it is formed, it can be coupled to each of the support pins 210, by inserting the auxiliary support pins 220 from top to bottom, respectively. When the support pins 210 and the auxiliary support pins 220 are coupled in this way, the upper surfaces of the support pins 210 and the auxiliary support pins 220 are placed at the same height, so that the lower portion of the wing plate 200 is in all directions. I can support it.

Next, the operation of the temporary beam support apparatus for slab formwork according to the present invention configured as described above will be described.

When supporting the temporary beams 300 as shown in Figure 6 by the slab formwork temporary beam support device according to the present invention, for example, the lower support 130 on the top of the copper bar, such as pipe support 320 Fasten with the fastening means (330).

Next, in a state in which the temporary beams 300 are disposed such that the wing 202 of the wing plate 200 is inserted into the insertion groove 312 of the connecting bracket 310 installed at the end of the temporary beam 300, the handle When the 160 is repeatedly turned up and down, the pinion 170 and the rack 102 are engaged with each other when the handle 160 is turned downward so that the elevating column 100 rises inside the support pipe 110. . In addition, the support pins 210 rise along the second slots 114 of the support pipes 110 with the elevation of the elevating column 100, and the wing plates 200 are around the support pipes 110. While rising together with the support pins 210, the temporary beams 300 are pushed up.

The vertical swing operation of the handle 160 as described above, the operator does not need to climb up to the side of the temporary beam 300, the handle extension member 166 in the coupling hole 164 of the handle 160 from the bottom By moving the handle extension member 166 up and down, it can be conveniently performed.

As described above, when the support pin 210 is caught on the upper end of the second slot 114 in the process of raising the lifting column 100, the rising of the lifting column 100 is stopped, and the height of the temporary beams 300 is increased. The height of the upper pedestal 120 is automatically adjusted horizontally. Therefore, the temporary beams 300 are supported by the pipe support 320 or the like in a portion other than the portion supported while connecting the temporary beams 300 in the above-described manner, and then the upper portions of the temporary beams 300. The slab formwork can be constructed by plates and reinforcing bars not shown, and concrete can be cured into slabs by pouring concrete into the constructed slab formwork.

On the other hand, when the slab is cured, the temporary beams 300 are dismantled, and after curing the slab for about 3 to 4 days, the pipe support 320 supporting the remaining portions except the connection portion of the temporary beams 300 After dismantling, and after about one month, dismantle the slab formwork temporary beam support device, the pipe support 320 and the temporary beams 300 of the present invention, which fixes the connection portions of the temporary beams 300. .

That is, when dismantling the temporary beams 300, when the handle 160 is fully turned upward, the engagement of the pinion 170 and the rack 102 by the disengagement means 190 is completely released, as shown in FIG. As shown, by the weight of the temporary beam 300, the wing plate 200 and the lifting column 100 can be automatically lowered together. Therefore, since one end of the temporary beams 300 are supported in a state inclined toward the wing plate 200, the temporary beams 300 may be easily dismantled. That is, the temporary beams 300 are placed in a state where they can be disassembled by one operation of the upturning of the handle 160. Even in this case, since the handle 160 can be fully pivoted upward from the bottom using the handle extension member 166, the worker can easily dismantle the temporary beam 300 in a safe state.

According to the slab formwork temporary beam support device according to the present invention configured as described above, since the lifting column 100 can be raised by the operation of repeatedly turning the handle 160, the slab formwork beam 300 Not only can easily support and support them, it is possible to safely install the temporary beams 300, thereby significantly reducing the time and cost for installing the temporary beams 300.

In addition, since it is possible to easily support the temporary beams 300 that are orthogonal to the front, rear, left, and right on the same plane, or are installed in the same straight line, not only can the temporary beams 300 be simplified, but also the amount of installation thereof can be reduced. have.

In addition, even when dismantling the temporary beams 300, the temporary beams 300 can be disassembled by only one operation of turning the handle 160 upward, so that the operator can easily disassemble the temporary beams 300 in a safe state. In this way, the time and cost for the temporary beam 300 dismantling work can be significantly reduced.

In addition, since the handle 160 can be rotated up and down by inserting the handle extension member 166 into the handle 160, the installation and dismantling work of the temporary beam 300 can be more easily performed.

In addition, since the structure of the wing 202 of the wing plate 200 needs to be installed at the end of the temporary beam 300 without having to install a complicated structure such as a beam neck, it is possible to standardize the temporary beam 300. have.
