Abstract
The utility model discloses a supporting rod with a length adjusting device. The supporting rod comprises an inner steel tube on the upper portion, an outer steel tube on the lower portion and the length adjusting device between the outer steel tube and the inner steel tube. The length adjusting device comprises an outer tube, an inner tube and a length adjuster, wherein external threads are arranged at the end of the outer tube, the diameter of the inner tube is smaller relative to the diameter of the outer tube, insertion holes are formed in the wall of the inner tube, and the length adjuster is composed of a ring nut, spanners and insertion pins. The inner tube is inserted into the outer tube, the insertion pins are inserted into the insertion holes of the inner tube, the ring nut is in threaded connection with the outer tube with the external threads, and the spanners are arranged on the outer wall of the ring nut. Length errors which are generated in the processes of manufacturing and installing the component can be avoided, so that connection is reliable.
Description
Technical field
The utility model relates to civil engineering steel work technical field, is specifically related to a kind of support bar of strip length adjusting device.
Background technology
Communication tower is as tall and slender structure, and the load effect under wind action is the major control load of himself structure and basic calculation, and basis must provide enough drags to guarantee that superstructure entirety does not occur and topples.
As the support bar that connects tower body and foundation steel framework, conventional way is to adopt the support bar otic placode of regular length to connect tower body and steel frame.This is high to the required precision level of making and install, and can not well to tower body inclining degree, regulate and control.And the difference of different according to the height of tower from wind reference pressure, causes foundation steel framework size difference, the length of the support bar of connection tower body and steel frame is different, causes the kind of support bar too much, is unfavorable for the batch making assembling of support bar.
Utility model content
The purpose of this utility model is in order to solve by the problem of making, alignment error causes support to connect or to regulate and control, or is beneficial to batch making in order to reduce support kind, and convenient installation, provides a kind of support bar of strip length adjusting device.
The technical solution adopted in the utility model is: a kind of support bar of strip length adjusting device, comprises the interior steel pipe on top, the outer steel pipe of bottom and length adjustment device between the two; Described length adjustment device comprises:
An externally threaded outer tube of end band;
Relatively described outer tube of diameter is less and on tube wall, opened the inner tube of jack;
A length adjuster being formed by ring nut, spanner and latch;
Described inner tube is inserted in outer tube, and described latch inserts in the jack of inner tube, and described ring nut is connected with being with externally threaded external pipe thread, and the outer wall of ring nut is provided with spanner.
As preferably, the jack side on described inner pipe wall is provided with the graduation mark that indicates length.
As preferably, described spanner is two, on the outer wall of described ring nut, is symmetrical arranged.
The support bar of the utility model strip length adjusting device is a kind of supporting rod that can suitably regulate according to actual demands of engineering rod member length, can be used for because fabrication and installation error causes installing among difficult Practical Project.Length adjustment device comprises jack section and adjustable sleeve two parts, respectively can be for coarse adjustment and fine tuning.Coarse adjustment is by latch, to insert corresponding jack to complete corresponding length adjustment operation.When it regulates length to be no more than a jack interval, by adjustable sleeve, complete the step-less adjustment operation of corresponding length.
Outer tube is the relatively large sleeve pipe of the externally threaded diameter of one end band, inner tube is that diameter is relatively little and on tube wall, opened the intubate of jack, intubate is inserted in sleeve pipe, utilize the latch can the larger error in length of coarse adjustment support bar, carry out stepless fine tuning with adjustable sleeve adjuster, adjustable range is thread segment length.
Beneficial effect: the utility model can solve the tower body bottom rigid support of the simple and easy self-support single-pipe tower of counter weight type, because fabrication and installation error causes installing a difficult difficult problem.
The utility model can solve the problem of the simple and easy self-support single-pipe tower of counter weight type to the regulation and control of tower body inclining degree.
The utility model can solve the be more or less the same problem of unitized, standardized production of rod member of bar length.
The utility model also can solve the similar problem that need to regulate rod member length of roof tower and bundling antenna support.
The utility model also can solve the similar problem that need to regulate rod member length in building construction.
The support bar of the utility model employing adjustable length replaces the support bar of traditional regular length, easy to operate.
The utility model can conveniently be installed, and improves speed of application, the reduction of erection time, reducing the construction costs, and there is significant overall economic efficiency.
The utility model is the fabrication and installation essence innovation to solving Practical Project, has significant technological progress and significant social benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model support bar.
Fig. 2 is the structural representation of the utility model length adjuster.
The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing, the utility model is described further:
As shown in Fig. 1 and 2, a kind of support bar of strip length adjusting device, comprises the interior steel pipe on top, the outer steel pipe of bottom and length adjustment device between the two; Described length adjustment device comprises:
An externally threaded outer tube 2 of end band;
Relatively described outer tube 2 of diameter is less and on tube wall, opened the inner tube 1 of jack 3;
A length adjuster 4 being formed by ring nut 4.2, spanner 4.3 and latch 4.1;
Described inner tube 1 is inserted in outer tube 2, and described latch 4.1 inserts in the jack 3 of inner tube 1, and described ring nut 4.2 is threaded with being with externally threaded outer tube 2, and the outer wall of ring nut 4.2 is provided with spanner 4.3.
Jack 3 sides on described inner tube 1 tube wall are provided with the graduation mark that indicates length.Described spanner 4.3 is two, on the outer wall of described ring nut 4.2, is symmetrical arranged.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
