In most units of construction, for economic consideration, the above connection structure of the 6m long phi 48 multiplied by 3.0 steel pipe is generally adopted, and the concrete construction procedures are as follows: firstly, punching a steel pipe, then respectively placing a screw cap and a screw rod on a platform into two ends of the steel pipe, respectively fixing the screw cap and the screw rod by welding points on the holes, the supporting rods are screwed into the supporting rods for fixing during connection, the supporting rods are bolted according to the handbook of construction work, the weight of each supporting rod is about 20 kg, on one hand, the supporting rods are generally lifted by operators with two hands and then operated, in the operation process, if the labor consumption of workers is large and danger is easily caused if the workers rotate for a long time (only one minute is needed for rotating one joint), and the verticality of the joint also does not meet the standard requirement, on the other hand, the nut 2' is formed by punching a supporting rod, and then the nut is welded and fixed in the inner hole 4' of the support rod, the centering performance of the nut is poor due to the installation structure, the vertical load bearing capacity and the bending resistance of the support are reduced, the welding is not firm, the nut is easy to fall off, and potential safety hazards exist.
Still another structure is as shown in fig. 2 (prior art two), and construction unit directly saves the bolt, adopts sleeve pipe mode butt joint welded mounting structure, and the construction process is: firstly, manufacturing a sleeve, welding and fixing the sleeve at one end of a support rod, sleeving the previous support rod on the sleeve in construction, then welding a joint, and finally polishing a welding seam smoothly by using a polishing machine, taking the construction of a phi 41 multiplied by 3.0 support rod as an example, the concrete construction steps are as follows: firstly, a phi 41 multiplied by 3.0 sleeve 5' is manufactured (the length is about 400 mm); secondly, welding the sleeve 5' at one end of the support rod steel pipe; thirdly, inserting the support pipe steel pipe and then welding; this method is mainly time-consuming, labor-consuming and material-consuming.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a convenient to construct swift, labour saving and time saving, cost of manufacture low, to well just connect firm slipform construction supporting rod connection structure of neutrality.
In order to solve the technical problem, the utility model discloses a slipform construction supporting rod connection structure, including treating many spinal branch vaulting poles of connecting, wherein one end of every spinal branch vaulting pole is directly pressed into the pipe end that contracts through the pipe pressing machine, and the initiating terminal of the pipe end that contracts of every spinal branch vaulting pole has the arc transition part that forms through the pipe pressing machine suppression in-process, adjacent two one of them spinal branch vaulting pole in the bracing piece contract the pipe end insert in the non-pipe end of another spinal branch vaulting pole and utilize this arc transition part after the accurate location carry out welded fastening.
The reducing end of one of the supporting rods is in transition fit with the non-reducing end of the other supporting rod.
The length of the pipe contracting end of the supporting rod is 200-800 mm.
And the pipe reducing end of one supporting rod is inserted into the non-pipe reducing end of the other supporting rod and is welded along the circumferential surface of the arc transition part.
The support rod is made of a steel pipe.
The utility model has the advantages that:
the contracted pipe end can be directly inserted into the other supporting rod in the connecting process, the manufacturing cost is low, time-consuming and labor-consuming rotary connection operation is not needed any more, only circumferential welding is needed, the construction is very convenient and rapid, labor and time are saved, the connecting efficiency is greatly improved, meanwhile, two adjacent support rods have the same central axis, so that the requirement of the specification is met (because both ends are concentric circles), the structure with good alignment and integrated molding ensures that the connection has good firmness, avoids the potential safety hazard problem caused by poor connection reliability in the prior art, particularly an arc-shaped transition part is naturally formed in the pressing process, thereby the naturally formed arc transition part is skillfully utilized for accurate positioning in the connection process, therefore, the centering precision is further greatly improved, and the vertical load bearing capacity and the bending resistance are improved.
