Abstract
The utility model discloses the connection structure of a kind of arcuate corrugation steel plate and curved steel tube, including arcuate corrugation steel plate, curved steel tube, pin pipe, screw rod and connecting screw, connecting hole is respectively provided with arcuate corrugation steel plate and curved steel tube, pin pipe one end is welded on the connection hole of curved steel tube, the other end is connected with screw rod, and connecting screw is connected through the connecting hole on corrugated sheet steel with pin pipe.The steel pipe that the utility model solves fill concrete is difficult to the problem being connected with corrugated sheet steel；Pin pipe extends the length of threaded connection so that connection is more firm；Screw rod further enhances the tightness of connection；Corrugated sheet steel is with after concrete steel pipe bolt, forming one, its anti-lateral bucking ability greatly promotes；Simple in structure, construction is convenient.
Description
Technical field
It the utility model is related to steel-concrete combined structure, more particularly to the connection knot of a kind of arcuate corrugation steel plate and curved steel tube
Structure.
Background technology
The applicant has applied for the related patents of many steel-concrete combined structures, it mainly make use of arc concrete steel pipe
Extremely strong bearing capacity, the common stress of the pipeclay of arcuate corrugation steel plate and corrugated steel groove to the parcel of concrete steel pipe and
Support of the concrete steel pipe to corrugated sheet steel, both interact, and realize the stressed effect of 1+1 ＞ 2.But in view of in actual use
Concrete steel pipe is generally chosen and is relatively large in diameter, its cross section is largely above corrugated sheet steel groove, if so not to both
Effectively connected, concrete steel pipe lateral bucking easily occurs when being subject to cross component force, and concrete steel pipe once occurs
Unstability, then the intensity of total will weaken significantly, easily there is the phenomenon that collapses.
Utility model content
Purpose of utility model：The purpose of this utility model is to provide a kind of simple and reliable for structure, construction easily arc-shaped wave
The connection structure of line steel plate and curved steel tube.
Technical solution：The arcuate corrugation steel plate of the utility model and the connection structure of curved steel tube, including arcuate corrugation steel
Plate, curved steel tube, pin pipe and connecting stud, are respectively provided with connecting hole on arcuate corrugation steel plate and curved steel tube, pin pipe penetrates connection
Hole is connected with curved steel tube, and concrete is loaded in curved steel tube, and connecting stud is connected through connecting hole with pin pipe.
Pin pipe is welded with curved steel tube.The setting of pin pipe adds the length of threaded connection, improves the reliability of connection.
Preferably, the arcuate corrugation steel plate of the utility model and the connection structure of curved steel tube further include screw rod.
Pin pipe sets internal thread, and the corresponding one end of screw rod sets external screw thread, after steel pipe fill concrete, pin pipe, screw rod and
Concrete forms common force structure, strengthens the fastness of connection.
It is further preferred that one end that the screw rod is located at outside pin pipe extends to the periphery so that connection is more firm.
Beneficial effect：Compared with prior art, the utility model has the following advantages：Solves the steel after fill concrete
Pipe is difficult to the problem being connected with corrugated sheet steel；Pin pipe extends the length of threaded connection so that connection is more firm；Concrete coagulates
Gu after, screw rod further enhances the fastness of connection；Corrugated sheet steel is with after concrete steel pipe bolt, forming one, its anti-side
Greatly promoted to unstability ability；Simple in structure, construction is convenient.
Brief description of the drawings
Fig. 1 is the utility model curved steel tube cross-sectional view；
Fig. 2 is the curved steel tube cross-sectional view of the utility model fill concrete；
Fig. 3 is the cross-sectional view that the utility model arcuate corrugation steel plate is connected with curved steel tube.
Embodiment
The technical solution of the utility model is described further below in conjunction with the accompanying drawings.
The arcuate corrugation steel plate of the utility model and the connection structure of curved steel tube, including arcuate corrugation steel plate (1), arc
Steel pipe (2), pin pipe (3), connecting screw (4) and concrete (5).
Fig. 1 show curved steel tube cross-sectional view, and connecting hole, pin pipe (3) are set on the tube wall of curved steel tube (2) outside
Connecting hole is penetrated, and its one end is welded on curved steel tube (2) inner wall.In order to further strengthen the tightness of connection, Ke Yi
The other end of pin pipe (3) sets screw rod (6), and certainly, screw rod (6) can be straight screw rod or extend to the periphery
Screw rod.Pin pipe (3) carries internal thread, and the corresponding one end of screw rod (6) is equipped with external screw thread, the two is on curved steel tube (2) is penetrated
Tightened before connecting hole.
Then, in curved steel tube (2) interior fill concrete (5), as shown in Figure 2.Pin pipe (3) adds threaded connection length
Degree, so that the tightness of connection is added, and after concrete (5) solidification, pin pipe (3), screw rod (6) and concrete (5) are formed altogether
Same force structure so that connection is more firm.Preferably, one end that screw rod (6) is located at outside pin pipe extends to the periphery, and further increases
The strong fastness of connection.
As shown in figure 3, connecting screw (4) passes through the connecting hole on arcuate corrugation steel plate (1) and curved steel tube (2), with pin
Manage (3) to be threadedly coupled, realize the connection of corrugated steel (1) and the curved steel tube (2) after fill concrete (5).
Claims (5)
- A kind of 1. connection structure of arcuate corrugation steel plate and curved steel tube, it is characterised in that：Including arcuate corrugation steel plate (1), arc It is equipped with shape steel pipe (2), pin pipe (3), connecting stud (4) and concrete (5), arcuate corrugation steel plate (1) and curved steel tube (2) Connecting hole, curved steel tube (2) inner wall set pin pipe (3), and concrete (5) is loaded in curved steel tube (2), and connecting stud (4) is worn Connecting hole is crossed to be connected with pin pipe (3).
- 2. the connection structure of arcuate corrugation steel plate according to claim 1 and curved steel tube, it is characterised in that：The pin pipe (3) one end is welded in the inner wall of curved steel tube (2) connection hole.
