Description

Temporary worktable for placing walls {Temporary worktable}

Since the present invention is provided with a locking part at the upper end of the support bracket comprising a support bar on which the work footing is mounted, it can be easily fixed or dismantled to the wall formwork using the locking part, and there is no obstacle to the worker's passage, It is about a stationary temporary workbench for placing walls without fear of collapse.

Reinforced concrete structures complete the structure by installing the formwork and pouring and curing the concrete inside the formwork.

In general, for a vertical member such as a wall, a worker pours concrete from the upper part of the slab formwork into the lower wall formwork.

However, if the wall height is high or if wall concrete needs to be poured before the slab formwork is installed, such as an underground composite wall, a separate work platform for wall concrete pouring is required.

Therefore, in the prior art, scaffolding was installed outside the wall formwork, and workers performed concrete pouring work on the scaffolding.

However, in this case, it takes a lot of time to install and dismantle the scaffolding, and the scaffolding installation obstructs the passage of workers, and if the scaffold height is high, there is a risk of overturning or collapsing, which leads to safety accidents.

When an eccentric load is applied to one side of the working platform 4 of the temporary workbench 2, there is a possibility that the temporary workbench 2 is separated from the yoke 10 and falls while the support bracket 3 of the other side is lifted.

Accordingly, a locking pin 35 penetrating through the main bar 33 and the locking part 31 can be detachably provided to prevent the temporary workbench 2 from being separated from the yoke 10 by an external force. have.

The locking pin 35 may be disposed to be caught under the yoke 10 to prevent the locking portion 31 from being separated from the yoke 10 .

Through-holes 311 and 331 may be formed in the main bar 33 and the locking part 31 to pass through the locking pin 35 , respectively.

After installing the temporary work table 2 by mounting the locking part 31 on the yoke 10 , the locking pin 35 passes through the through holes 311 and 331 of the main bar 33 and the locking part 31 . ) to prevent the detachment of the temporary workbench 2 due to external force or eccentricity.

In addition, when dismantling the temporary workbench 2 , after dismantling the locking pin 35 , the temporary workbench 2 may be lifted.

When the yoke 10 is composed of a pair of upper and lower pipes, the locking pin 35 may be configured to pass between the upper and lower pipes.

The locking pin 35 can be fastened to the main bar 33 and the locking part 31 at an upper position of the work platform 4 . Therefore, the operator can easily install or dismantle the locking pin 35 .

The locking pin 35 is connected to one side of the support bracket 3 by a wire (W), thereby preventing the locking pin 35 from being lost.

6 is a perspective view showing another embodiment of the support bracket.

As shown in FIG. 6 , the support bracket 3 is provided with the support bar 32 in which the locking part 31 is formed at the front end, and inclined toward the wall formwork 1 from the rear end of the support bar 32 .

The fixture 36 may include a guide bolt 361 and a pressure tool 362 .

The guide bolt 361 passes through the third support bar 34c and can move forward or backward by rotation.

The pressing hole 362 is provided at the front end of the guide bolt 361 to press the front of the yoke (10).

The yoke 10 may be fixed by a locking part 31 on the back side and a pressing hole 362 on the front side. In this case, the temporary workbench 2 is not separated from the yoke 10 by an external force, and a firm fixed state can be maintained.

Specifically, as shown in FIG. 7 (a), the support bracket 3 is lowered from the upper part of the yoke 10, and then the guide bolt 361 is advanced as shown in FIG. The fixture 36 can be fixed in a state in close contact with the yoke 10 .

A through hole may be formed in the third support bar 34c to pass through the guide bolt 361 .

A guide nut 341 to which a guide bolt 361 is screwed may be fixedly coupled to one side of the through hole of the third support bar 34c.

A locking protrusion 363 caught in the lower portion of the yoke 10 may be formed protruding from the front surface of the pressing member 362 .

The locking protrusion 363 supports the lower part of the yoke 10 so that the locking part 31 does not fall out of the yoke 10 and is fixed even when an upward external force is applied.
