Abstract

The utility model relates to a lifting/lowering supporting head of a helical pipe for building construction. The lifting/lowering supporting head of a helical pipe is sheathed on the upper part of a single rod supporting post, the lower part of the steel pipe of the lifting/lowering supporting head of a helical pipe for building construction is provided with an outer thread, and the upper part of the lifting/lowering supporting head of a helical pipe for building construction is provided with a supporting plate. A rotatable nut is arranged on the outer thread. The rotatable nut is clamped and connected by a clamping pin on the single rod supporting post. The clamping pin is arranged inside a slot which is symmetrical to the opening of the outer thread. When the rotatable nut is rotated, the lifting/lowering supporting head of the helical pipe can move from top to bottom. The lifting/lowering supporting head of a helical pipe for building construction has simple structure, convenient use, and low cost. The lifting/lowering supporting head of a helical pipe for building construction can also make the bottom template of a building structure early disassembled.

Description

Architectural elevating helical pipe supporting head

The utility model belongs to the spiral tube lifting supporting member that a kind of building operation is used.

At present, the widely used various studs of building industry have scaffolding steel pipe, tool-type single tube pillar, four pipe steel struts, combined steel pipe pillar etc.These pillars all are that crossbar or the truss below the template supported on the top, must remove pillar earlier during form removal.Like this, when form removal and pillar, must reach the form removal intensity of " reinforced concrete construction and acceptance specification " regulation, therefore make striking time longer, make that a large amount of templates, template accessory and support system circulation material turn around time are long, the circulation material requirement is big in the construction, the engineering cost height.

The purpose of this utility model is in order to overcome the problem of above-mentioned stud, can not become flexible and remove the spiral tube lifting supporting member of pillar when a kind of form removal is provided, and template, template accessory and support system circulation material are early removed.

The utility model is to adopt such method to realize: the spiral tube lifting supporting member that building operation is used, be on common single pole pillar, to be with a spiral tube lifting supporting head, the centre of spiral tube lifting supporting member is that a bottom has externally threaded steel pipe, the top of steel pipe is one and has the steel plate back plate that is welded to connect, has a circular hole on the back plate, the both sides on steel pipe top, below the back plate be two and have the symmetrical steel floor that is welded to connect, in the steel pipe lower thread part, has a radial opening symmetrical channels, have a nut on threaded portion, a side of nut has a round steel rotary handle.Have a radial symmetry circular hole on single pole pillar top, a round steel bayonet lock is housed in circular hole, the sponson two ends of bayonet lock are connected in the symmetrical channels of threaded portion, and are supporting nut.During by the rotary handle swivel nut, the motionless and back plate lifting of single pole pillar.

The utility model is compared with existing technology, has characteristics simple in structure, in light weight, easy to process, that use is also convenient, cost is low.Be fit to be installed on the single pole pillars such as tool-type single tube pillar, scaffold tubes pillar and use.And be installed on the single pole pillar, reduction reinforced beam, plate structure end template are removed required concrete strength, are easy to form removal early, the reduction of erection time, reduce engineering cost.

Concrete structure of the present utility model and embodiment are provided by the following drawings.

Fig. 1 is the overall structure scheme drawing of the utility model spiral tube lifting supporting member for building.

Fig. 2 is the structural representation of the utility model spiral tube lifting supporting member.

Fig. 3 is the structural representation of looking up of the utility model spiral tube lifting supporting member.

Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are made further instruction.

See shown in the accompanying drawing 1,2,3: the spiral tube lifting supporting member that building operation is used, pillar upper boom 5 of grafting on pillar lower beam 1, be with a spiral tube lifting supporting member 6 on 5 on the pillar upper boom, has small-sized gang form 11 on the top of pillar upper boom 5, on pillar lower beam 1, have outside thread 7, on screw thread 7 parts, have radial opening symmetrical channels 8, on outside thread 7, have nut 2, on nut 2, have rotary handle 3, on pillar upper boom 5, have the bayonet lock 4 that radial direction through hole passes.

Lower end at spiral tube lifting supporting member 6 has outside thread 7, the upper end has back plate 10, has a radial opening symmetrical channels 8 in outside thread 7 parts, on outside thread 7, cooperate a nut 2, on nut 2, has a rotary handle 3, at bayonet lock 4 of the lower end of nut 2 (in the opening symmetrical channels 8) clamping, bayonet lock 4 is fixed by the radial direction through hole of pillar upper boom 5.

Have two floors that are symmetrically welded 9 in spiral tube lifting supporting member 6 upper ends, on back plate 10, have a through hole.

When construction, at first according to reinforced beam or plate bottom surface height, adjust the height of tool-type single tube pillar, make mounting plate than cement concrete at the bottom of absolute altitude low slightly, after needs form removal early, leave the position of pillar, layout is with the tool-type single tube pillar of spiral tube lifting supporting member, and drawknot makes pillar firm in length and breadth, then, and by rotary handle 3 swivel nuts 2, make back plate 10 rise to the upper limit, crossbar, gang form are installed on back plate.After casting concrete, following of normal temperature needs maintenance 3～4 days, can pass through rotary handle 3 swivel nuts 2, makes back plate 10 declines and pillar is motionless.Dismountable immediately other pillar and crossbar and other template that withstands on below the crossbar, at this moment, though concrete strength is much smaller than the form removal intensity of " standard " regulation because pillar still supporting cement concrete, institute so that the support of cement concrete needs be guaranteed.So just reached the purpose of form removal early.

Claims
