Abstract

The utility model relates to a lifting scaffold used for the construction operation of high-rise buildings. The utility model is mainly formed by that three steel beam assemblies are installed on the outer wall (beam) of a building, and the head part of the upper steel beam is hung with a calabash of which the lower hook can hook a bottom on the inner side of the scaffold. When in use, the up-and-down movement of a calabash chain can drive the scaffold to ascend or descend, and guide wheels are fixed on the steel beam assemblies and are matched with guide rails fixed on the scaffold; anti-dropping devices are arranged between the steel beam assemblies and the guide rails. The utility model has the advantages of reasonable structure, high integral rigidity, material saving, etc., and the utility model can effectively improve the safety factor and the production efficiency of building operation.

Description

Raise scaffold
Affiliated technical field
The utility model belongs to building engineering construction device technique field, relates to a kind of scaffold that is used for the high-building construction operation.
Background technology
High-building construction is used the of a great variety of scaffold on the domestic and international market at present, differs from one another, and has obtained the patented product---hoisting scaffold (patent No. is ZL96236380.4) that country is authorized comprising the utility model applicant.The work structuring of this scaffold as shown in Figure 2, be characterized in the outside of building 1 by on the next installation twice girder steel assembly 3, head (center of construction scaffolding 9) at following girder steel hangs cucurbit 5, the lower draw-bar of cucurbit 5 hooks the bottom of scaffold 9, and moving up and down by the cucurbit chain during work drives the rising or the decline of scaffold; End at girder steel assembly 3 is provided with directive wheel, and in scaffold 9 processes of rising or falling, the guide rail that is fixed together with support body 2 moves up and down along directive wheel, thus limited scaffold 9 inside and outside topple; When the unexpected disconnection of cucurbit chain, anti-drop device 8 can be in time locked with guide rail 2, prevented the tenesmus of scaffold 9.After this hoisting scaffold enters enforcement, by engineering verification in the past few years, 1., the termination of girder steel assembly puts in the scaffold find that it also has following weak point:, scaffold is when lifting, because being parallel to the horizontal pipe support (leger) of building wall interferes mutually with girder steel, so leger must be disconnected, so just influence the integral rigidity (this also is the common fault of most of raise scaffolds) of scaffold; 2., owing to all leger will be disconnected in the position that girder steel is arranged, both strengthened working strength of workers, also brought unnecessary trouble to construction.In addition, in high-building construction in recent years, the use of large form is more and more frequent, the large form hanger that matches with the exterior wall large form has appearred thereupon, but present hanger well known in the art all needs to promote with tower crane, and when tower crane plays hanger, also need the people to stand on the hanger to cooperate tower crane to promote and fixing hanger, operation is absolutely unsafe.
The utility model content
The purpose of this utility model is to develop a kind of structure and more become rationally and can replace the raise scaffold of large form hanger for overcoming weak point that the above-mentioned background technology exists, thus make it to realize to ensure high-building construction safely, enhance productivity, the effect and the effect of economical with materials.
The technical solution that adopts is so to achieve the above object of the invention: the raise scaffold that is provided has the girder steel assembly of three roads by the packing of upper, middle and lower position, hang cucurbit at last girder steel head, the lower draw-bar of cucurbit hooks the inside bottom of scaffold, and moving up and down by the cucurbit chain during work drives scaffold and rise or descend; Outer end at the girder steel assembly is provided with directive wheel, is provided with the guide rail that cooperates with directive wheel in the scaffold inboard, scaffold rise and the decline process in, guide rail moves up and down along directive wheel, limited scaffold inside and outside topple.In addition, be provided with anti-drop device between girder steel assembly and guide rail, when the cucurbit chain meets accident when prominent disconnected, anti-drop device is can be in time locked with the guide rail that is fixed together with support body, has prevented the tenesmus of scaffold, guarantees construction safety.
Compare with aforementioned background art, advantage of the present utility model is:
1, guide rail is located at the inboard of scaffold, girder steel assembly and scaffold mutually noninterfere, and frame pipe (leger) need not disconnect, and has improved the integral rigidity of scaffold; In addition, the utility model also promotes the seat in the plane at each and is provided with the facade main frame, is provided with the horizontal support framework in the bottom of scaffold, has further strengthened the integral rigidity of scaffold;
2, maximum 2.5~3 layers of only needing the covering floor of the scaffolding height of scaffold have fully been saved construction material (steel pipe, fastener, scaffold floor and safety net etc.);
3, when project subject is constructed, this raise scaffold can be with the exterior wall large form to rise together, without the tower crane lifting, has both saved hanging device, has overcome unsafe factor again; During exterior decoration, remove large form, this raise scaffold can be used as the finishing frame again and descends voluntarily;
3, change original guide pad into directive wheel, be about to the scaffold up-down mode and change rolling friction into, reduced frictional force by sliding friction;
4, turnover part volume is little, in light weight, has alleviated working strength of workers greatly, has also effectively improved construction safety coefficient and production efficiency simultaneously.

The specific embodiment
Referring to accompanying drawing, raise scaffold described in the utility model comprises scaffold support body 9 and is connected girder steel assembly 3 members such as grade that cooperate with scaffold 9.Scaffold 9 can be set up with the common steel tube fastener, and the frame height is about 2.5~3 times of single story height, satisfies the needs of main body construction and finishing.Girder steel assembly 3 comprises three roads, distinguishes by last girder steel, middle girder steel and following girder steel, and is vertically fixed on the exterior wall (beam) of building 1 with through-wall bolt assembly 4 respectively.Hang cucurbit 5 at following girder steel head (inboard of scaffold 9), the lower draw-bar of cucurbit 5 hooks the inside bottom of scaffold 9.Be provided with directive wheel 10 in the outer end of girder steel assembly 3, be provided with the guide rail 2 that cooperates with directive wheel 10 in scaffold 9 inboards, guide rail 2 is that gathering sill moves up and down along directive wheel 10 with scaffold 9 with the profile of two channel-section steels during work, limited scaffold inside and outside topple.Between girder steel assembly 3 and guide rail 2, be provided with by brake wheel 12 and skewback 11 form and can with the anti-drop device 8 of cucurbit 5 interlock, when the cucurbit chain is unexpected prominent disconnected, the brake wheel 12 of anti-drop device can roll downwards under the drive of guide rail 2, in time that scaffold is locked aloft under skewback 11 effects, thereby prevented the tenesmus of scaffold 9, the safety of assurance personnel and equipment.
