Description

[Detailed explanation of the invention] [Industrial field of application] This invention relates to a large temporary material receiving device, which is connected to pipe supports and attached to formwork when constructing concrete floor slabs for buildings, factories, etc. The support beams that hold the floor slabs are supported and fixed via large timbers,
The present invention also relates to a temporary lumber receiving device for dismantling floor slabs after construction.

[Conventional technology] Conventionally, in the construction work of concrete slabs in buildings, factories, etc., the formwork slabs are held on support beams that are appropriately erected and supported, and concrete material is poured onto the formwork slabs. and solidify.

At this time, the support beams are erected and supported between the upper ends of the constructed wall sections or between the stands of pipe supports, and when dismantled, they are separated from the solidified concrete slab. When separating, the support beams and the formwork slabs supported by them are first dropped slightly, and then the connections between each member are released and dismantled.

In particular, when supporting beams are supported and fixed on pipe supports that stand in a forest, a temporary large lumber receiving device called a drophead is connected to the pipe support, and the lumber is supported in parallel between the dropheads. Install support beams in between. That is, the drophead includes a support and fixing mechanism for supporting the support beam at a predetermined height position, and a drop mechanism for slightly dropping the support beam.

As an example, there is a concrete pouring panel support and explanation device disclosed in Japanese Utility Model Application Publication No. 59-167147. This is designed to fix the position of the elevation locking plate and allow it to fall via an actuating member having a wedge action using a protrusion provided at the intermediate portion of the support shaft.

[Problems that the invention attempts to solve] However, according to the conventional support and explanation devices,
When the position is fixed, the load is supported while being supported by the protrusion, so it is difficult to support a large load and there are restrictions on use.

Therefore, this invention was made in order to eliminate the above-mentioned conventional drawbacks, and aims to provide a large temporary material receiving device that has excellent load resistance and is easy to handle.

[Means for Solving the Problems] In order to solve the problems of the conventional method, this invention consists of a base body that is connected to a forest of pipe supports and is provided with pillars, and a base body that is slidable in the vertical direction of the pillars. A support body that is attached to the outside of the column and engages and supports the end of the large tension material, and is inserted into a falling groove that is opened vertically along the lower part of the support, and is inserted into a falling groove in the vertical direction along the falling groove. It is characterized by comprising an operating wedge that slides and supports the support at a predetermined height position by being inserted into and engaged with a support notch formed at the upper end of the drop groove.

[Function] The temporary lumber receiving device of this invention is used by being connected to pipe supports set up at a site where a concrete slab is to be constructed.

That is, the operating wedge is connected to the pipe support, is slid upward within the drop groove, and is inserted into and engaged with the support notch at the upper end of the drop groove.
A support is supported on this operating wedge.

By engaging the ends of the large tension members with the support body supported at a predetermined height position on the pillar, the large tension members are supported in a suspended state, and the supporting beam is constructed between the parallel large tension members. The equipment is fixed and the formwork slab is placed on the support beam.

When the construction of the concrete slab on the formwork slab is completed, the engagement with the support notch is released by driving the operating wedge, the operating wedge falls to the bottom of the support, and at the same time a large pull-out occurs. The timber also fell, and the formwork slab and support beams separated from the concrete slab.

Therefore, each component is disassembled and the whole thing is disassembled. These operations are performed by sliding the operating wedge and support body along the up and down direction of the column, and sliding the operating wedge in the front and back direction. This is done by engaging or disengaging with the support notch.

supports the bulkheads 22 that frame and fix the supporting beams 23 that hold the formwork slabs 24 when constructing the concrete floor slabs. The support body 5 itself is made up of a rectangular cylindrical sliding tube 6 that fits around the pillar 3, and an engaging piece 7 that engages the large tension member 22. 6 are bent in a pair of left and right sides to have an L-shaped cross section that expands outward on both sides from the upper end, so that the ends of the large tension members 22 are engaged in the engaging pieces 7 . Further, as shown in the figure, a strip-shaped stop piece 8 is provided on both ends of the upper edge of the engaging piece 7 to prevent the end portion of the large tension member 22 from being pulled out or displaced when the end portion is engaged. At the center of the upper edge of the engaging piece 7, a round bar-shaped stop rod 9 is protrudingly provided for positioning when engaging the end portion of the large tension member 22.

In order to reinforce the support body 5 itself, a trapezoidal reinforcing brace 10 is formed between the sliding tube 6 and the engagement piece 7, and the upper end of this reinforcing brace 10 is formed into an L-shaped engagement. The horizontal portions of the pieces 7 are made to protrude upward to prevent the engagement pieces 7 from becoming distorted.

The support body 5 formed in this way is connected to the operating wedge body 1
1, it is supported and fixed at a predetermined position on the pillar 3,
Further, it is assumed that it is dropped to the lower position of the column 3, and this is done by the operation wedge 11 inserted through the column 3.

The operating wedge 11 moves up and down along a drop groove 12 that is opened in the vertical direction at a height corresponding to the height position at which the support body 5 is supported at a predetermined position at the lower part of the column 3. A wide support notch 13 is formed at the upper end of the drop groove 12 so as to communicate with the drop groove 12, and the drop groove 12 as a whole has a vertically elongated T-shape.

On the other hand, the operating wedge 11 itself engages with a narrow sliding portion 14 that slides within the falling groove 12 in the vertical direction along the falling groove 12 through the support notch 13, and the operating wedge 11 It is integrated with a wide support part 15 that supports and stops itself in the upper position. This operating wedge 11
