The utility model discloses simple accurate, it is firm reliable, compensate the defect of traditional butt joint fastener, show improvement efficiency of construction, have very strong spreading value.
Description
Technical Field
The utility model relates to a connection structure for steel pipe butt joint.
Background
With the social progress and the improvement of the construction technology level, a high-efficiency, quick and reliable construction mode is gradually favored by project managers. The traditional steel pipe fastener scaffold is a common construction mode in engineering, and is particularly widely applied to concrete structure construction.
The traditional fastener type steel pipe connection wastes time and energy, is difficult to control torque, has different standards, is easy to loose when bearing dynamic load, and even has the phenomenon of collapse due to the loosening of the fastener.
Disclosure of Invention
The utility model discloses aim at overcoming prior art's defect, provide a connection structure for steel pipe butt joint, solve job site steel pipe fastener and connect and take a lot of work and time, easily not hard up scheduling problem that drops.
In order to solve the technical problem, the utility model discloses a realize like this:
the utility model provides a connection structure for steel pipe butt joint which characterized in that: the steel pipe and the steel pipe butt joint device comprise connecting pieces, bolts and spring clamps, wherein the connecting pieces are bamboo-shaped, through holes are formed in two ends of each connecting piece, the diameter of each connecting piece is smaller than the inner diameter of a steel pipe to be connected, the steel pipe to be connected is in plug-in butt joint with the two ends of each connecting piece, and the bolts are inserted into the through holes of the connecting pieces and the through holes of the steel pipes and.
A connection structure for steel pipe butt joint, its characterized in that: the diameter of the connecting piece is 2mm smaller than the inner diameter of the steel pipe to be connected.
The utility model has the advantages that: the application range is wide: the connecting device is suitable for connecting the steel pipes of the support frames and the decorative scaffolds with various diameters, and can also be used for butt joint of the steel pipes with different diameters; the functionality is strong: the axial pressure and the tensile force of the connected steel pipes can be borne; the operation is simple and convenient: a single worker can quickly complete the operation process; the spring clamp is stable and reliable, the bolt is not easy to loosen and fall off in the use process, and the connection is reliable; can design according to actual demand, batch factory production, it is convenient to retrieve, and the loss is low.
Drawings
The invention will be described in further detail with reference to the following drawings and embodiments:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic side view of fig. 1.
Detailed Description
As shown in fig. 1 and 2: the utility model provides a connection structure for steel pipe butt joint, it includes connecting piece 4, bolt 2 and spring card 3, the connecting piece is bamboo joint shape and both ends are equipped with the through-hole respectively, and the diameter of connecting piece is less than the internal diameter of required connection steel pipe 1, and the steel pipe of required connection and the bayonet butt joint in connecting piece both ends, bolt insert the through-hole of connecting piece and steel pipe and lock through the spring card.
Furthermore, the diameter of the connecting piece is 2mm smaller than the inner diameter of the steel pipe to be connected.
Through the practical inspection of a high formwork system, the connecting piece can be used for mounting 10 sections of matched gantries with the height of 1.8m at the highest, the load of 110KN is borne, and the shearing force of 80KN can be borne by the bolt. The requirements of the general engineering template support system on the erection height and the stability are met.
