Abstract
The utility model relates to a coupling device used for steel pipes of a construction scaffold, wherein the coupling device mainly comprises an inner pipe, a strengthening pipe and a connector which are combined with each other. The inner pipe is combined with an upper steel pipe and a lower steel pipe, then the combined upper steel pipe and the lower steel pipe and the inner pipe are coated by the strengthening pipe in order to strengthen the rigid integration degree among the pipes and the inner pipe, finally, the combined assembly is fixedly connected by connectors such as a bolt.
Description
Technical field
The utility model relates to a kind of coupling device that is used for the building scaffold steel pipe, refers to a kind of coupling device that can scaffold firmly be combined especially.
Background technology
Existing because population is constantly soaring, the demand of house also constantly improves, and is just carrying out so the streets and lanes of taking a broad view usually just has some fortification; And these building fortification are when carrying out; Whether for construction worker's safety, or, all can around building fortification main body, erect the scaffold of a circle for pedestrian's on the road safety; Simultaneously, also convenient construction personnel migration successfully around building body.
Suitable simple of the basic structure of these scaffolds; Usually be exactly that two steel pipes utilize double-screw bolt or bolted joints together, thereafter, then carry out the extension of all directions again, be centered around building fortification body suitable net structure body all around and cause formation one.When the network structure body of this type utilizes double-screw bolt or bolt to combine, because joint all around all is that to utilize double-screw bolt or bolt to be used as be its stressed strong point, so the network structure body of this type is when doing the protection of low floor; Still can be competent at the responsibility that it is undertaken; Yet, it for example is five layers, seven layers in case the floor of protection improves ..., the increase that the overall weight of then whole network structure body can be rapid; Under this situation; Since the joint of steel pipe all be by double-screw bolt or bolt as media so that all weight (load) all is to be carried by double-screw bolt or bolt, therefore; As long as the joint between steel pipe and steel pipe has not positive situation to take place slightly, the situation that then can rupture at an easy rate or fracture by joint.
When this situation takes place, the light then net structure body avalanche of part, heavy then the damage of personnel's property takes place; Therefore, no matter be for the personnel of construction, or for the other people around walking in building fortification body, the scaffold that existing techniques is used can't provide suitable protective action really.
For fear of the unfortunate event that causes because combination is bad taking place, the purpose of the utility model promptly is to provide a kind of coupling device that is used for the building scaffold steel pipe.
The utility model content
Be the problem of solution existing building scaffolding steel pipe joint poor effect,, the utility model provides a kind of coupling device that is used for the building scaffold steel pipe, and it mainly has:
Pipe in one, its caliber is less than the scaffolding steel pipe internal diameter;
One spacer assembly, it is that the steel pipe up and down that is arranged at the pipe outside in this is separated, and is formed on this interior pipe lateral wall;
One enhanced tube, it is arranged on the pipe outside in this; And
One conjunction, it is to wear pipe and this enhanced tube in this.
The aforementioned coupling device that is used for the building scaffold steel pipe, it still has the elastic body that is arranged on this conjunction.
Aforementioned spacer assembly is to be formed at the protruding grain on the pipe outer side surface in this.
The aforementioned coupling device that is used for the building scaffold steel pipe is to have the conjunction of confession to pass through perforation wherein on this enhanced tube.
Aforementioned elastic body is a spring.
Be to be provided with the groove of strengthening its surface strength on the aforementioned enhanced tube outside wall surface.
Cooperating with next that the utility model is appended graphicly does more detailed explanation to the utility model each item embodiment; It should be noted that; Wherein narration is relevant for each item embodiment of the utility model, and its purpose only is explanation, and does not have the effect of any restriction; Both having made wherein has any term that can be considered restriction, and it is also still defined by the statement that uses in the appended claims.
Description of drawings
Fig. 1 is the utility model decomposing schematic representation;
Fig. 2 radially makes up the section structural scheme of mechanism for the utility model; And
Fig. 3 axially makes up the section structural scheme of mechanism for the utility model.
The specific embodiment
The utility model relates to a kind of coupling device that is used for the building scaffold steel pipe; The main purpose of building scaffold is in the engineering of building fortification is carried out; Set up a firm protection body all around at building fortification body; Thereby can be to the constructor who is being engaged in the building fortification, or near the personnel that walk the fortification in building provide enough protections.
Please referring to shown in Fig. 1 the utility model decomposing schematic representation, wherein the utility model coupling device of being used for building scaffold steel pipe 9 comprises pipe 4 in a conjunction, the enhanced tube 3 and;
This conjunction is preferably by a nut 1 and a bolt or double-screw bolt 2 (present embodiment is to be that example is explained with the double-screw bolt) combines;
This enhanced tube 3 mainly is made up of two arc lamellar bodies; Be to have a corresponding each other perforation 31 to wear on it on each lamellar body; So when two lamellar bodies were combined into a tubular body each other, the perforation 31 that is separately positioned on each lamellar body was alignment each other and coincide.
Should in pipe 4 be to have comprised that one has the hollow tube of both ends open, then be provided with a through hole 41 and a spacer assembly on body.Best, this spacer assembly is one group of protruding grain 6 that is oppositely arranged on this tube wall face.
It then is the cylinder that can be set in this double-screw bolt 2 that the coupling device that the utility model is used for the building scaffold steel pipe is provided with an elastic body (preferably is helical spring 5) in addition.
Cooperation is referring to Fig. 2, shown in 3, and the utility model at first is that interior pipe 4 is set between two steel tube end parts of desiring to be bonded together when practical operation, that is the outer tube diameter of interior pipe must be the internal diameter less than steel pipe; After sheathed completion, two steel pipes of desiring to be bonded together can be set at respectively then that spacer assembly on pipe 4 outside wall surface separates in this, with avoid steel pipe all of a sudden to be linked in each other together or let in pipe fall among the steel pipe.Then be double-screw bolt 2 with conjunction pass perforation 31, through hole 41 interior pipe 4 on and perforation 31 opposite side enhanced tube 3 lamellar bodies on enhanced tube 3 lamellar bodies on thereafter.Afterwards, then be that the double-screw bolt that utilizes this nut 1 will pass enhanced tube 3, interior pipe 4, enhanced tube 3 is locked together in together tightly.
It should be noted that in this between lamellar body of outer wall and this enhanced tube 3 both sides of pipe 4, can add an elastic body 5 again.This elastic body 5 is to be resisted against between the internal face of outside wall surface and enhanced tube 3 each lamellar body of pipe 4 in this respectively; So, when removing nut 1 on by this double-screw bolt 2, because the effect of elastic body 5, each sheet of enhanced tube 3 is known from experience and is automatically peeled away the steel pipe that it coated, and can accomplish the action of dismounting quickly and easily.
