Abstract
The utility model relates to an adjustable steel support with an improved structure. The adjustable steel support comprises an outer tube, wherein external threads are formed on the upper end of the outer tube, and a kidney slot which penetrates through tube walls of both sides is formed in the external thread section of the outer tube; an inner tube is inserted and sheathed into the outer tube, and a plurality of round holes which penetrate through the tube walls of the both sides are vertically distributed in the inner tube; both ends of a pin shaft respectively penetrate through the round holes of the inner tube and the kidney slot of the outer tube, so as to press against the top plane of a thread bushing which is screwed on the external thread section of the outer tube; the lower end of the outer tube is divided into a lower tube and an upper tube, and opposite external threads are formed on the upper end of the lower tube and the lower end of the upper tube; the upper end of an internal thread tube is screwed on the lower end of the upper tube, the lower end of the internal thread tube is screwed on the upper end of the lower end, and a slotted hole which penetrates through the tube walls of the both sides is formed in the middle of the internal thread tube. The thread outer tube is utilized to screw the adjustable steel support together, the steel support is extended and shortened through rotation of the thread outer tube, and additionally, the tube wall of the thread outer tube is thickened, so that the tube wall is difficult to deform when the tube wall is beaten, thereby prolonging the service life of the steel support.
Description
Technical field:
The utility model relates to the technical field of building-supporting, more specifically to a kind of adjustable steel support of architecture advances.
Background technology:
It is the desirable fastenings of construction project such as building, mine, tunnel, bridge, culvert that adjustable steel supports, it have stable performance, can free adjustment height, be repeatedly used with simple in structure, support the advantages such as convenient.And after present Practical Completion, remove when adjustable steel supports is that figure dismounting is quick and convenient, the way of site operation personnel convention is to utilize the instruments such as iron hammer, beam column to knock in the lower end of outer tube, thereby being supported, steel tilts to remove steel support, but there is hidden danger in this kind of dismounting mode, while sometimes knocking outer tube, overexert and can make the lower end of the outer tube shape of just changing, thereby inner tube does not enter in the outer tube of distortion place during retraction inner tube.The intensity that the distortion meeting of outer tube lower end is supported steel simultaneously exerts an influence, and the accident of shining into likely appears bending and in distortion place of outer tube.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of adjustable steel of architecture advances to support, and can when removing fast, avoid outer tube to deform, thereby can guarantee that the integrality that steel supports can reclaim use.
Technology solution of the present utility model is as follows:
A kind of adjustable steel of architecture advances supports, comprise outer tube, outer tube upper end forms external screw thread, on the outer tube of external thread section, form the kidney slot that runs through both sides tube wall, in outer tube, be inserted with inner tube, in inner tube, be vertically distributed with the circular hole that several run through both sides tube wall, the two ends of bearing pin are pressed against in the top plane of thread bush through the circular hole of inner tube and the kidney slot of outer tube respectively, thread bush is screwed onto on the outer tube at external screw thread place, the lower end of described outer tube is divided and is truncated into two sections of lower pipe and upper pipes, the upper end of lower pipe and the lower end of upper pipe form contrary external screw thread, the upper end of riffled tube is screwed onto the lower end of pipe, the lower end of riffled tube is screwed onto the upper end of lower pipe, the middle part of described riffled tube forms the slotted eye that runs through both sides tube wall.
The screw thread of the slotted eye top of described riffled tube is contrary with the screw thread of slotted eye below, and the thread rotary orientation of slotted eye top is consistent with the thread rotary orientation of lower pipe upper end, and the thread rotary orientation of slotted eye below is consistent with the thread rotary orientation of upper pipe lower end.
The pipe thickness of described riffled tube is 3～4 times of outer tube wall.
One end of described bearing pin is extended and is bent and is bending part.
The beneficial effects of the utility model are:
The lower end of the outer tube that it supports steel is divided into two sections, and utilize screw thread outer tube to be screwed together, and the rotation by screw thread outer tube is supported steel to extend and shorten, and the tube wall of screw thread outer tube is thickeied simultaneously, it is beaten not yielding, thereby has increased the application life that steel supports.
Accompanying drawing explanation:
Fig. 1 is easy structure schematic diagram of the present utility model;
Fig. 2 is the cross-sectional schematic of the utility model outer tube lower end.
In figure: 10, outer tube; 20, inner tube; 30, bearing pin; 40, thread bush; 50, riffled tube; 11, lower pipe; 12, upper pipe; 51, slotted eye.
The specific embodiment:
Embodiment: see Fig. 1, shown in 2, a kind of adjustable steel of architecture advances supports, comprise outer tube, outer tube 10 upper ends form external screw thread, on the outer tube 10 of external thread section, form the kidney slot that runs through both sides tube wall, in outer tube 10, be inserted with inner tube 20, in inner tube 20, be vertically distributed with the circular hole that several run through both sides tube wall, the two ends of bearing pin 30 are pressed against in the top plane of thread bush 40 through the circular hole of inner tube 20 and the kidney slot of outer tube 10 respectively, thread bush 40 is screwed onto on the outer tube 10 at external screw thread place, the lower end of described outer tube 10 is divided and is truncated into 12 two sections of lower pipe 11 and upper pipes, the lower end of the upper end of lower pipe 11 and upper pipe 12 forms contrary external screw thread, the upper end of riffled tube 50 is screwed onto the lower end of pipe 12, the lower end of riffled tube 50 is screwed onto the upper end of lower pipe 11, the middle part of described riffled tube 50 forms the slotted eye 51 that runs through both sides tube wall.
The screw thread of slotted eye 51 tops of described riffled tube 50 is contrary with the screw thread of slotted eye 51 belows, and the thread rotary orientation of slotted eye 51 tops is consistent with the thread rotary orientation of lower pipe 11 upper ends, and the thread rotary orientation of slotted eye 51 belows is consistent with the thread rotary orientation of upper pipe 12 lower ends.
The pipe thickness of described riffled tube 50 is 3～4 times of outer tube 10 tube walls.
One end of described bearing pin 30 is extended and is bent and is bending part.
Operating principle: when carrying out the removing of adjustable steel support, can utilize a reinforcing bar to be inserted on the slotted eye 51 of riffled tube 50, because of the upper pipe 12 of its outer tube 10 contrary with the external screw thread of lower pipe 11, during riffled tube 50 rotation, make screw thread simultaneously tight or simultaneously loose, can time regulate the gap between pipe 12 and lower pipe 11, rotation riffled tube 50 reduces the gap between upper pipe 12 and lower pipe 11, thereby energy just can be by steel supporting removal.The steel pipe that is simultaneously thickening because of its riffled tube 50, the intensity of being beaten is stronger, and it is difficult for deforming, and has increased the application life that steel supports.
