Abstract

The utility model discloses a scaffold for the construction, in particular to a self-elevating scaffold attached to wall for replacing a prior multi-vertical member steel tube scaffold, which overcomes the defects that prior suspended scaffolds can not be self-elevating. The utility model comprises a plurality of sleeve framework racks which are arranged along the wall surface of the building in the horizontal direction; the sleeve framework racks are placed with scaffold boards. The scaffold attached to the wall can be self-elevating via lifting apparatuses, such as a jack, etc. Thus the overlapping of the scaffold has the advantages of simple operation, investment saving, safe use, and good utility.

Description

Wall bearing self-lifting scaffold

The utility model relates to building operations and architectural decoration operation scaffold.

In building operations, especially in high-building construction, need set up scaffold, in order to satisfy the needs of building operations and architectural decoration operation.Continuous development along with design of building structures and architectural construction technology, especially construction technologies such as more employing sliding formwork, large form and gang form in highrise building, above-mentioned scaffold mostly is many pole steel tubes scaffold greatly, and this scaffold desired structure material is more, and sets up troublesome poeration and set up and remove the required cycle of scaffold long etc.In addition, usually also use a kind of suspended scaffold, but because this suspended scaffold self can not lifting, and to make its lifting by the jacking equipment that is located at this suspended scaffold outside, complicated because of its elevating method, thereby in building operations, seldom adopt this suspended scaffold.

The utility model scaffold is exactly in order to adapt to the needs of architectural construction technology development, with in order to replace above-mentioned suspended scaffold, and attempt replacing or partly replacing above-mentioned many pole steel tubes scaffold, and simple but practical attached wall self the Liftable type scaffold device of a kind of structure is proposed.

The utility model scaffold has a plurality of hangers that are made of an inner sleeve framework and an outer tube framework, described hanger is arranged along the horizontal direction of building wall, and make described outer tube framework slip big envelope on described inner sleeve framework, have being connected partly of some energy and described fabric structure spare phase mount on described inner sleeve framework and the outer tube framework respectively, can make respectively to produce between described inside and outside cover tube frame and relatively move by being installed in manual crane gear in the described scaffold.

The major advantage of the utility model scaffold is that its energy self carry out lifting, can not self lifting thereby overcome original suspended scaffold, and the shortcoming that can not extensively be promoted the use of, simultaneously, the utility model scaffolding structure is simple, and set up and remove easily, and small investment, be hopeful to be used for replacing or partly replace many pole steel tubes scaffold that extensive at present custom adopts, this helps improving building operations efficient and reduces investment outlay.The utility model scaffold is suitable for the high-building construction occasion especially, and adopts the occasion of architectural construction technologies such as large form and climbing forms.

Structural representation when Fig. 1 is connected for the sleeve pipe framing component of the described sleeve pipe shaped as frame hanger of expression formation and with fabric structure spare mount.

Fig. 2 uses the utility model scaffold when a certain actual high-building construction for expression, and described sleeve pipe shaped as frame hanger is along the skin configuration schematic diagram.

Fig. 3 connects partly structural representation for the part of the described sleeve pipe framing component of expression.

Now referring to (a) among Fig. 1,1 is described sleeve pipe framing component, it by outer tube framework (3) big envelope on inner sleeve framework (2), and can in inner sleeve framework (2), move freely and form, inner sleeve framework (2) is fixedly connected by welding by two steel tube poles 2 and some web members 6 and forms rectangular frame, outer tube framework (3) is by two steel tube poles 3 and some web members 6 ' form rectangular frame by welding, the structure length of outer tube framework (3) is about about one meter (distances of the two adjacent screws through walls that stay along the building structural member vertical direction when being equivalent to construction approximately), be provided with by welding on one side at it and all right one way or the otherly be mounted with the hook 7 that is connected with fabric structure spare, at its web member 6 ' be mounted with scaffold board support 5 that connection can be shelved scaffold board 4. On one side of inner sleeve framework (2) by welding be provided with all right one way or the other and fabric structure spare be mounted with the hook 7 that is connected ', has scaffold board support 5 with the scaffold board shelved 4 of above-mentioned same configuration form at its web member 6, the structure height of inner sleeve framework (2) is about (the structure height sum that is equivalent to approximately two common scaffold operation element layer heights and a jacketing frame (3)) about four meter five, two vertical rods 2 at inner sleeve framework (2) are respectively equipped with the pin hole that a row can insert the insurance pin, are used for addition rod 11 being installed and being inserted the insurance pin when making 1 lifting of cover tube frame.

Be positioned at the jack type hydraulic lifting on the web member seat board of outer tube framework (3) among Fig. 1 (a) Equipment 9 schematically illustrates the state when preparing lifting or decline inner sleeve framework (2), when wanting inner sleeve framework (2) is promoted, the adjacent two inner sleeve frameworks (2) of arranging along the same level direction are promoted simultaneously, therefore need there be two described jack type hydraulic lifting equipments 9 to work simultaneously, by install and fix addition rod 11 temporarily, when outer tube framework (3) and fabric structure spare being mounted be connected, unclamp the connecting bolt of inner sleeve framework (2) and fabric structure spare, can allow jack start working, inner sleeve framework (2) is promoted step by step, inner sleeve framework (2) is always promoted about one meter, generally need to change the position about three of addition rod 11 on inner sleeve framework (2), four times, just can finish once always promoting of inner sleeve framework (2). When wanting inner sleeve framework (2) is descended, for inner sleeve framework (2) is descended, must make earlier inner sleeve framework (2) a bit of distance that rises, can withdraw from from the fastening bolt that is connected with fabric structure spare, and then make its decline, in addition, the operation sequence of its rising and decline is all identical with main points, generally also need change about three, four times of the position of addition rod 11 on inner sleeve framework (2), just can finish once always descending of inner sleeve framework (2).

State when Fig. 1 (b) expression prepares outer tube framework (3) is risen, when wanting outer tube framework (3) is promoted, the two adjacent outer tube frameworks (3) of arranging along the same level direction are promoted simultaneously, when inner sleeve framework (2) and fabric structure spare being mounted be connected, unclamp the connecting bolt of outer tube framework (3) and fabric structure spare, can allow jack start working, the outer tube framework is promoted step by step, outer tube framework (3) is always promoted about one meter, by interim installing addition rod, generally also need change the position about three of addition rod on inner sleeve framework (2), four times, just can finish once always promoting of outer tube framework (3). When wanting to make outer tube framework (3) to descend, its operation sequence is substantially identical with the operation sequence when making inner sleeve framework (2) decline.

In addition, the gap of 5～10mm is arranged approximately between vertical rod 2 and vertical rod 3 tube walls, be beneficial to overlap the mount of tube frame 1 and fabric structure spare.

The utility model scaffold also has two-layer scaffold operation element layer, and described scaffold floor support 5 can connect by bolt makes it be connected with

vertical rod

2 or 3 phase mounts, also can itself and
