Problems solved by technology

If the traditional process is used to install plastic sleeves (the plastic sleeves cannot be effectively and firmly combined with the profiled steel plate) when the concrete is poured, the position is prone to shift. Dismantling using flame cutting or electric cutting machine) The above two methods will lead to a waste of a lot of manpower and material resources
After the profiled steel plate is opened and cut, when pouring concrete, it will cause the opening to sink, and the construction quality cannot be guaranteed
[0003] Therefore there is above-mentioned inconvenience and problem in the support mode of known hole concrete formwork

Embodiment 1

[0031] The quick-detachable supporting device of the present invention is used for pre-embedded casing pipe holes, reserved holes, and holes of profiled steel plate floor slabs, and includes a base, a vertical pole, and a hole-blocking cover.

[0032] see now figure 1 , figure 1 It is a structural schematic diagram of the supporting device of the embodiment of the present invention. As shown in the figure, the base is a top wire 2, and the top wire is vertically arranged on the template 1 on the upper surface of the profiled steel plate floor plate, and the top of the top wire is provided with a top wire adjusting nut 3.

[0033] Described upright bar is common scaffolding steel pipe 4, and the bottom end of upright bar is supported on jackscrew adjusting nut, and the top of upright bar bears against the formwork 1 below the hole that covers upper laminated steel plate floor plate.

[0034] The hole cover includes an inverted T-shaped bracket, a rubber plug 6, and a cover pl...

Embodiment 2

[0036] The method for using the quick-detachable support device of the present invention comprises the following steps:

[0037] a. Use a plasma cutting machine to cut out the holes that need to be left on the upper laminated steel plate.

[0038] b. Use ordinary scaffolding steel pipes and adjustable top wires to support the 40cm*40cm waste formwork at the bottom of the hole in the profiled steel plate to prevent the steel plate from collapsing due to hole cutting.

[0039] c. Weld an inverted T-shaped piece by using waste pull-up screws and grounded galvanized flat steel waste, drill 4 holes in the flat steel of the inverted T-shaped piece, and fix it on the formwork with nails or screws.

[0040] d. Use a rubber tube with a thickness of 4mm to stuff it into the cut hole, use the waste template to punch a round hole in the center to make a pressure plate device for pressing and fixing the rubber tube, and fix the pull screw and the compression screw to make the hole pre-buri...

Abstract

The invention provides a rapid disassembling type supporting device used in pre-buried sleeve holes, preformed holes and holes of pressed type steel plate floor slabs. The rapid disassembling type supporting device comprises a base, a vertical rod and a hole blocking cover. The rapid disassembling type supporting device is characterized in that a jackscrew (2) is adopted as a base, a common scaffold steel pipe (4) is adopted as the vertical rod, the hole blocking cover comprises an inverted-T-shaped support, a rubber plug (6) and a cover plate (8), the rubber plug is provided with a communicating hole communicating up and down, a bottom plate of the inverted-T-shaped support (5) is a section of flat steel plate provided with a plurality of through holes, the flat steel plate is fixed to aformwork (1) below the flat steel plate through screws (7), a screw rod penetrates through the through holes of the rubber plug upwards, and then penetrates through the cover plate arranged on the topface of the rubber plug, the cover plate is pressed through nuts, and the rapid disassembling type supporting device is formed. The rapid disassembling type supporting device and a using method thereof have the advantages that the supporting device is simple in structure and convenient to manufacture, the engineering quality is safe and reliable, the installing efficiency is improved greatly, thelabor cost is saved by about fifty thousand yuan, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a support frame for a concrete formwork, in particular to a quick-detachable support device and its application method. Background technique [0002] Caofeidian Comprehensive Free Trade Zone Innovation and Entrepreneurship Center 1#~4# office building has a total floor area of ​​110,000 square meters above ground, all of which adopt steel frame structure, with an average floor height of 3900mm. The floor slab is a composite floor 1mm thick profiled steel plate. About 5,300 pipe holes need to be reserved for the profiled steel plate floor slab, which is an extremely large number. Because it is a profiled steel plate composite floor slab and there are steel bars inside, the code does not allow the use of water drills to open holes after the concrete is poured, so a plasma cutter must be used to cut holes on the profiled steel plate before concrete pouring, and then add casing, etc. After pouring initial setting for a period of ...
