Abstract
The utility model relates to an architectural steel pipe scaffold, particularly to a joint type steel pipe scaffold. The utility model is composed of steel pipes, joints, straight joints, set screws and diagonal rod connecting pieces. The steel pipes are processed into steel pipes with the length of fifteen kinds of standard specifications, the diagonal rod connecting pieces, the steel pipes and the set screws are connected and combined into diagonal rods through bolts, the steel pipes are connected together by the joints, and the joint type steel pipe scaffold is combined. When the scaffold is used in a template support system, the support height is adjusted by the set screws, and two steel pipes are connected by the straight joints to satisfy the span of buildings. The steel pipes do not need to be cut off whether the utility model matches any scaffold, and only steel pipes with different length are selected to collocate required length.

Description
Technical field
The utility model relates to a kind of steel pipe scaffold for building, connects steel pipe with joint, straight joint, jackscrew, brace connector, specifically is a kind of joint type steel pipe scaffold.
Background technology
In the construction of building and structure, mainly adopt fastener type steel pipe scaffold and bowl fastening type steel pipe scaffold.Fastener type steel pipe scaffold mainly is the formwork bracing system that is used in exterior wall scaffold and cast-in-situ steel reinforced concrete framework, and its advantage is: cost is low, the steel pipe highly versatile.Its shortcoming is: exterior wall scaffold is comparison danger when setting up, and the scaffolder who sets up scaffold must be through training, and ability is on duty behind the card that qualifies.Steel pipe is by tightening the bolt on the fastener with being connected of fastener, the bond stress of leaning on fastener that steel pipe is produced is transmitted load, so its bearing capacity is little, when being used for formwork bracing system, the formwork bracing system that can only be used for the less cast-in-situ steel reinforced concrete framework of load, and can not be used for the formwork bracing system of the bigger cast-in-situ steel reinforced concrete member of load, as cast-in-place bridge culvert, stadiums etc.The bond stress that fastener produces steel pipe is to realize by the bolt of tightening on the fastener by operating personnel, operating personnel's working attitude and quality directly have influence on the size of bond stress, so the unsafe factor during scaffold building is more, so often there is security incident to take place.The advantage of bowl fastening type steel pipe scaffold is: power transmission is reliable, bearing capacity is big, people's influence factor is less.Its shortcoming is: rod member is not general, and vertical rod and horizontal bars are special-purpose rod member, can not exchange; The two ends of steel pipe are provided with connector, its transportation and stacking and inconvenience thereof, and cost height.So the bowl fastening type steel pipe scaffold only is used for the bigger formwork bracing systems of load such as cast-in-place bridge culvert, stadiums.
Summary of the invention
In order to change the mode of occupation of existing steel pipe scaffold, the utility model provides a kind of joint type steel pipe scaffold, that this joint type steel pipe scaffold is installed is simple, convenient, power transmission is reliable, safety, standard, bearing capacity height, the advantage of existing fastener type steel pipe scaffold also has the advantage of bowl fastening type steel pipe scaffold.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of joint type steel pipe scaffold comprises by steel pipe, ordinary couplings, diagonal brace joint, the joint of encorbelmenting, straight joint, jackscrew, brace connector, brace and forming.Described steel pipe two ends respectively have two to perforation,, with bolt steel pipe and joint are linked together after on the joint at steel pipe socket.Described ordinary couplings is maximum joint that the joint type steel pipe scaffold is used, connect vertical rod and horizon bar by ordinary couplings, the steel pipe that can connect six direction, joint is connected with bolt with steel pipe, act on the load on the horizontal cross bar, be delivered to by steel pipe on the cambered plate of joint, be delivered on the vertical steel pipe by joint again.Described diagonal brace joint is to be used for exterior wall scaffold, connects the joint of diagonal brace, during installation brace is enclosed within on the screw rod of brace joint, then tightening nuts.The described joint of encorbelmenting is when being used for exterior wall scaffold and having the shelf of encorbelmenting and cast-in-place formwork bracing system that the shelf of encorbelmenting is arranged, and forms builder's jack by the straight plate bracing diagonal of the joint of encorbelmenting.Described straight joint is when being used for formwork bracing system, with straight joint two joint steel pipe is synthesized different length to adapt to the span of beam slab.Described jackscrew is to be used for cast-in-place formwork bracing system, adjusts the height of template; When being used for the composition of brace, can be with any one size of brace furnishing to satisfy the needs of brace length.Connector when described brace connector is the combination brace; Be combined into a joint brace by two brace connectors, two joint steel pipes, a jackscrew.
The beneficial effects of the utility model are: the one, and economical, compare with the fastener type scaffold, can save 12% steel pipe consumption, the use amount of joint is 3/7ths of a fastener use amount.In addition, the weight of a standard fastener is the shortage in weight 1kg of a joint of 1.25kg, can save a large amount of steel and expense, and transportation and stacking and convenient.The 2nd, standard, highly versatile is processed into the length of 15 kinds of standard specifications with steel pipe, in the scope that standard allows, the scaffold of various different spacing of one-tenth capable of being combined and asynchronous distance, because steel pipe is of a size of full-length, the scaffold of setting up must rule; Because the stressed of joint rationally can bear very big load, the interchangeability of rod member is very strong, so can set up various forms of scaffolds and formwork bracing system.The 3rd, safety simple to operate, because the longest steel pipe has only 195cm, weight is no more than 7.5kg, operating personnel can finish setting up of scaffold easily, setting up of scaffold is upwards to set up length by length, so do not need special scaffolder, general constructor all can set up; When steel pipe is connected with joint, as long as bolt is screwed on, security incident can not appear even without tighting a bolt yet, thus safety the during installation that has improved scaffold greatly and the safety when using.

The specific embodiment
Steel pipe is divided into 195cm, 180cm, 165cm, 150cm, 135cm, 120cm, 105cm, 90cm, 75cm, 60cm, 30cm, 25cm, 20cm, 15cm, 10cm15 kind full-length, can set up all kinds of scaffolds of different spacing and asynchronous distance in the scope that standard allows.The following steel pipe of 60cm is mainly used in formwork bracing system and combination brace.
As shown in Figure 8, form brace by brace connector (17), steel pipe (19) and jackscrew (20) with bolt (18), brace mainly is used in the diagonal brace of exterior wall scaffold and the brace when encorbelmenting.Select the synthetic required brace length of two steel pipe of different length for use,,, the length of brace can be transferred to length arbitrarily with jackscrew, to satisfy the needs of brace length so increase a jackscrew because the minimum modulus of steel pipe length is 50mm.
Steel pipe is connected with joint: steel pipe socket on the cambered plate of joint, is linked together steel pipe and joint with bolt.Setting up of exterior wall scaffold sees Figure 10 for details.
Set up the cast-in-situ beam slab support system as shown in Figure 9 with the joint type steel pipe scaffold, the upper end of each vertical steel pipe all is provided with a jackscrew, increase a jackscrew at the position that beam is arranged again,, can set up the building of any floor height with the height that the steel pipe and the jackscrew of different length are adjusted support system.This following steel pipe of side, its length is combined into needed length by two steel pipes by straight joint, can adapt to the building of any span.
