Abstract

The utility model relates to a column head for an early disassembling system, which belongs to a building tool. The column head for an early disassembling system is composed of a supporting plate, a beam support, T-shaped pins, a column body, a connecting pipe and a round pin, wherein, two steel plates are bent to be opposite to form the column body, and the column body is weld with the supporting plate and the connecting pipe. The middle of the column body is provided with a pin opening. The beam support is composed of a beam ear, a support and a square sleeve pipe. The front part and the rear part of the square sleeve pipe are provided with T-shaped pin openings which are corresponding with each other. When a template beam is additionally added, the beam support is upwards lifted. The T-shaped pins are knocked into the T-shaped pin openings and pin openings, the wide surfaces of the T-shaped pins are just positioned on both ends of the T-shaped pin openings of the beam support to be used as supporting surfaces, and the contact surfaces of the column head for an early disassembling system are the wide surfaces of the T-shaped pins. The stability of the column head for an early disassembling system is high. The column head for an early disassembling system is suitable for a small steel mould system. The column head for an early disassembling system has the advantages of high stability, convenient use, simple processing and low cost.

Description

Column head for early dismantling system

The utility model belongs to the building frock

In builing industry, quote little punching block from the seventies since, development has basically formed system rapidly, becomes the main template of using in the present building operations of China.

Along with the develop rapidly of highrise building industry, it is more and more incompatible that the form of construction work of little punching block has seemed.One of them important deficiency is the early removing system that its support system also lacks a kind of practicality.

Early tearing column cap open, is to be contained in to regulate on the column, and its corbel is hung with Form beam, and two shoulders of Form beam are laid little punching block, can cast-in-situ concrete on little punching block.

Be that column cap is early torn in 89208032.9 hot investment casting open as the patent No. in the prior art, its main defective is:

When its supporting plate 4 places between corbel 3 and the following backing pin 5 with location corbel height, because the contact surface of supporting plate 4 and following backing pin 5 very little (promptly descend the thickness of backing pin 5 very little), when setting up Form beam and little punching block, rock back and forth easily, stability is not high, can cause the of low quality of cast-in-situ floor, in addition because it is hot investment casting processing, the processing cost height, the weight of whole column cap is also heavier.

The purpose of this utility model is: provide a kind of being applicable to tear column cap morning little punching block system, that stability is high, that process simply, save steel and weight open.

The utility model is made up of supporting plate 1, corbel 2, shaft 4, tube connector 5, it is characterized in that:

Shaft 4 is formed after by two block plate bendings relatively, open with lock-joint 11 centre, shaft 4 upper ends and supporting plate 1 welding, weld mutually with tube connector 5 lower end, corbel 2 is welded by beam ear 7, support 8 and square casing 9, square casing 9 front and back have corresponding T shape lock-joint 10, and corbel 2 places the supporting plate 1 and 5 of the tube connectors of shaft 4 and can move up and down.When setting up Form beam, corbel 2 is upwards carried by foot, make the T shape lock-joint 10 and the lock-joint 11 of shaft 4 be in same position, T shape pin 3 is squeezed into from T shape lock-joint 10 by having of garden lock-joint 13, make a wide 14(A to B of T shape pin 3) be in two ends of the T shape lock-joint 10 of corbel 2, and insert with pin 6 at garden lock-joint 13 places, make corbel 2 be positioned the certain altitude of shaft 4, be the height 55mm that certain value is little punching block with the distance H on the last plane of the last plane that guarantees corbel 2 and supporting plate 1.Because the height of corbel 2 of the present utility model location is to depend in the T shape lock-joint 10 that T shape pin 3 is inserted in the lock-joint 7 of shaft 4 and corbel 2, its contact surface is wide 14 of T shape pin 3, it is long to be (A to B), and this just makes it that high stability is arranged, and can not produce the phenomenon of rocking.

When early stripping formwork system, T shape pin 3 is hit the back side that the A end that makes T shape pin 3 surpasses corbel 2 forward, narrow 15 centre joint 11 places that are positioned at shaft 4 of T shape pin 3, corbel 2 promptly falls voluntarily.

The utility model compared with prior art has the following advantages:

(1). because the height of corbel 2 location is to realize that with the lock-joint 7 of shaft 4 its contact surface is very big by the T shape lock-joint 11 of T shape pin 3 insertion corbels 2, can produce and rock back and forth, stability is very high.

(2). early tear several critical pieces of column cap open, as corbel 2, shaft 4 etc. by the sheet material bending and be welded.Therefore technology is simple, and material economy, weight are light approximately by 25%, and price is lower.

Accompanying drawing is described in conjunction with the embodiments

The utility model is to be used for the little punching block early removing system that the cast-in-place concrete floor building is used.For regulating column, on a plane of lower support system, an one direction is the interval with the length of Form beam in the bottom of early tearing column cap open, and other direction is the interval with the length of little punching block, forms a support system.Hang with Form beam on the beam ear 7, two Form beam structure of an essay are with little punching block.Behind the fluid concrete, when its intensity reaches the 5C% left and right sides, beat T shape pin 3, corbel 2 is fallen, take off Form beam, template, mould support etc. and drop into it in order to save cost with hammer.
