Abstract
The invention discloses a supporting rod with a length adjusting device. The supporting rod comprises an inner steel pipe at the upper part, an outer steel pipe at the lower part and the length adjusting device arranged between the inner steel pipe and the outer steel pipe, wherein the length adjusting device comprises an outer pipe provided with an external thread at the end part, an inner pipe which has the diameter smaller than that of the outer pipe and is provided with an insertion hole in the pipe wall, as well as a length adjuster consisting of a ring nut, spanners and an inserted pin; the inner pipe is inserted into the outer pipe; the inserted pin is inserted into the insertion hole of the inner pipe; the ring nut is in threaded connection with the outer pipe provided with the external thread; and the spanners are arranged on the outer wall of the ring nut. According to the supporting rod with the length adjusting device, the problem of a length error generated during component manufacturing and mounting can be solved, and reliable connection is guaranteed.
Description
?
Technical field
The present invention relates to civil engineering steel work technical field, be 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 integral body 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 of regular length to connect tower body and steel frame with otic placode.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 different, and the length of the support bar of connection tower body and steel frame is different, causes the kind of support bar too much, be unfavorable for the batch making assembling of support bar.
Summary of the invention
To the object of the invention is in order solving by the problem of making, alignment error causes support to connect or to regulate and control, or to be beneficial to batch making in order to reduce support kind, convenient installation, provides a kind of support bar of strip length adjusting device.
The technical solution used in the present invention 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 strip length adjusting device of the present invention is a kind ofly can suitably regulate the supporting rod of rod member length according to actual demands of engineering, 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 and operate.When it regulates length to be no more than a jack interval, the step-less adjustment that completes respective length by adjustable sleeve operates.
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, with adjustable sleeve adjuster, carry out stepless fine tuning, adjustable range is thread segment length.
Beneficial effect: the present invention 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 present invention 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 present invention can solve the be more or less the same problem of unitized, standardized production of rod member of bar length.
The present invention also can solve the similar problem that need to regulate rod member length of roof tower and bundling antenna support.
The present invention also can solve the similar problem that need to regulate rod member length in building construction.
The present invention adopts the support bar of adjustable length to replace the support bar of traditional regular length, easy to operate.
The present invention can conveniently install, and improves speed of application, the reduction of erection time, reducing the construction costs, and there is significant overall economic efficiency.
The present invention is to solving the fabrication and installation essence innovation of Practical Project, having significant technological progress and significant social benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of support bar of the present invention.
Fig. 2 is the structural representation of length adjuster of the present invention.
The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing, the present invention will be further described:
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.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
