Abstract
The utility model relates to a steel pull rod. The utility model comprises a plurality of rod bodies, connecting sleeves and/or adjusting sleeve barrels and bias rectifying devices, wherein the connecting sleeves are used for connecting adjacent rod bodies and the bias rectifying devices are arranged on the rod bodies. The bias rectifying devices of the steel pull rod of the utility model change plane contact between a nut and a shim in a traditional steel pull rod into sphere contact. A spherical nut and a concave shim plate with a spherical surface can rotate in any direction of a circular arc surface, and the spherical nut and a concave inner sleeve barrel with a spherical surface can also rotate in any direction of a circular arc surface; consequently, automatic adjustment within a range of 2 DEG in any direction can be realized. The problem of nonuniform stress between the shim plate and the nut when the rod bodies of the steel pull rod is tilted are effectively solved. The utility model also has the advantages of simple and easily implemented construction, financial resource saving and material resource saving.
Description
Technical field
The utility model relates to a kind of connecting elements of long span building thing, specifically, relates to a kind of reinforcing pull rod.
Background technology
Reinforcing pull rod is an important component of building the long span building thing, in the reinforcing pull rod installation process, because the connected structure construction deviation that all has end plane angle and position more or less, and the extent of deviation of angle and position is not quite identical, backing plate and nut unbalance stress when the body of rod tilts, additional being articulated and connected can only be realized unidirectional adjustment, realize that universal adjustment need increase many fixtures, consumption manpower, financial resources are bigger, the most important thing is that duration of a project and workmanship have been subjected to influence.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of and can regulate the reinforcing pull rod of deviation automatically.
The utility model reinforcing pull rod comprises some bodies of rod, connects the adapter sleeve and/or the regulating sleeve of the adjacent body of rod and is arranged on deviation correcting device on the body of rod.
Described deviation correcting device is the end deviation correcting device that is arranged on body of rod outer end, reinforcing pull rod one or both ends.
Described end deviation correcting device comprises the sphere matrix backing plate that is sleeved on body of rod outer end, end successively and the ball-type nut of spinning, and described sphere matrix backing plate matches with described ball-type nut.
Described deviation correcting device is to be arranged on the reinforcing pull rod one or both ends body of rod to be adjacent deviation correcting device between bar between the body of rod.
Deviation correcting device comprises the fastening outer sleeve that is installed in body of rod inner end, end thread segment between described bar, sphere matrix inner sleeve and spinning that is fastenedly connected with described outer sleeve and the ball-type nut that is fixed on the body of rod end adjacent with the body of rod, described ball-type nut matches with described sphere matrix sleeve.
Deviation correcting device is one between described bar, also comprises an end deviation correcting device that is positioned at the described reinforcing pull rod other end.
It is that sphere contacts with plane contact between the pad that the utility model reinforcing pull rod has changed traditional nut, when the body of rod has certain inclination, the body of rod drives nut and rotates together, spherical nut and sphere spill pad are concentric, the ball-type nut is concentric with sphere matrix inner sleeve, also are the sphere contact after the anglec of rotation.The utility model reinforcing pull rod can be realized regulating automatically in 2 ° of scopes of any direction, the problem of backing plate and nut unbalance stress when efficiently solving the inclination of the reinforcing pull rod body of rod, and it is simple to construct, and has saved financial resources, material resources.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model reinforcing pull rod structural representation;
Fig. 2 is the end deviation correcting device structural representation of the utility model reinforcing pull rod;
Fig. 3 is a deviation correcting device structural representation between the bar of the utility model reinforcing pull rod.
The specific embodiment
Referring to Fig. 1, a kind of reinforcing pull rod shown in Figure 1, comprise both ends body of rod I, III and middle body of rod II, IV, wherein body of rod II, IV are fastenedly connected by adapter sleeve 8, body of rod III, IV connect by regulating sleeve 7, comprise that also the end deviation correcting device that is installed in body of rod III outer end, end and end body of rod I are adjacent deviation correcting device between bar between the body of rod II.Wherein, the body of rod quantity in the reinforcing pull rod can increase and decrease according to actual conditions.
Referring to Fig. 2 and Fig. 3, end shown in Figure 2 deviation correcting device comprises the sphere matrix backing plate 1 that is sleeved on body of rod III outer end, end successively and the ball-type nut 2 of spinning, and sphere matrix backing plate 1 matches with described ball-type nut 2, also is the cambered surface contact after the two anglec of rotation.Deviation correcting device comprises the fastening outer sleeve 3 that is installed in body of rod I inner end, end thread segment between bar shown in Figure 3, sphere matrix inner sleeve 4 and spinning that is fastenedly connected with outer sleeve 3 and the ball-type nut 5 that is fixed on the body of rod II end adjacent with body of rod I, ball-type nut 5 matches with sphere matrix sleeve 4.Outer sleeve 3 and body of rod I spin partly, ball-type nut 5 spins with body of rod II partly is provided with holding screw 9, and outer sleeve 3 adopts interior hexagonal to spend shape sunk screw 6 to fixedly connected with the barrel of sphere matrix inner sleeve 4.
It is that sphere contacts with plane contact between the pad that the utility model reinforcing pull rod has changed traditional nut, ball-type nut and sphere matrix backing plate, ball-type nut and sphere matrix sleeve both can be in any direction rotations of arc surface, can regulate automatically in the 2 ° of scopes in side arbitrarily at circular arc, improved the work force-bearing situation of reinforcing pull rod, and it is simple to construct, only need antiseepage routinely to assemble in the Installation and Debugging process, this has just improved operating efficiency, and workmanship also is provided simultaneously.
