Abstract
An upper and lower reinforcement connection device in a bridge pier column reinforcement cage comprises ribbed reinforcements, an inner sleeve and an outer sleeve; the inner sleeve and the outer sleeve with the inner wall with threads are arranged on the outer side of the ribbed reinforcements in turn in a sleeving mode; the inner sleeve comprises a thread section and extension sections; the extension sections are arranged at two ends of the thread section respectively; the inner wall of the thread section is provided with threads which are matched with threads formed on the ribbed reinforcements; the outer wall of the thread section is provided with threads which are matched with the threads of the outer sleeve. According to the upper and lower reinforcement connection device in the bridge pier column reinforcement cage, the outer side of the ribbed reinforcements is provided with the inner sleeve and the outer sleeve and accordingly the problem that a half sleeve length of thread section is exposed out in the prior art is solved, the strength is ensured, and the installation is simple and convenient.
Description
Technical field
The utility model belongs to the technical field of cement concrete pavement, is specifically related to the device that in a kind of bridge pier column reinforcing cage, upper and lower reinforcing bar connects.
Background technology
Mechanical connection technique of reinforcement development in recent years is rapid, and especially the development of roll extrusion straight thread reinforced bar sleeve link technique is very fast, but all rebar connecting technologies are all used in building trade at present, and straight screw sleeve link technique all connects for single steel bar, and in bridge industry, start at present to have construction team straight screw sleeve link technique to be applied in the connection of bridge pier column reinforcing cage, but when reinforcing cage docking, descending reinforcing cage is fixing, only have upper reinforcing cage to rotate, therefore while adopting sleeve to install, can only rotational sleeve, because reinforcing cage is heavier, therefore whole sleeve all can only be rotated on reinforcing bar above, after reinforcing cage aligns, being rotated down sleeve connects again, after installing, reinforcing bar above can expose the thread segment of half cover tube length, this can weaken the bulk strength of reinforcing cage greatly, affect the application life of bridge, in addition, upper descending reinforcing cage is to timing, be not that all reinforcing bars can align completely, always some reinforcing bar cannot align, and while adopting sleeve to install, need to force reinforcing bar to align by external force and install, going up like this eccentric throw that a reinforcing bar has timing will be added on next root reinforcing bar, in the time that eccentric throw reaches some values, it is abnormal difficult that installation will become, and sometimes even cannot install.
Utility model content
The purpose of this utility model is to provide the device that in a kind of bridge pier column reinforcing cage, upper and lower reinforcing bar connects, and has simple installation, the advantage that intensity is large.
For achieving the above object, the utility model adopts following technical scheme: comprise Ribbed Bar and be sleeved on successively inner sleeve and the threaded outer sleeve of inner wall belt in Ribbed Bar outside, wherein, inner sleeve comprises thread segment and is arranged at the lengthening section at thread segment two ends, thread segment inwall is provided with the screw thread that matches with the screw thread in Ribbed Bar, is provided with the screw thread that the screw thread of outer sleeve matches on thread segment outer wall.
The thickness of described lengthening section is less than the thickness of inner sleeve, and is less than the thickness near thread segment away from the thickness of thread segment.
Described inner sleeve is divided into two parts vertically.
Two parts of described inner sleeve are fixed by tied silk.
On the outer wall of described outer sleeve, be provided with for spanner card and groove.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by being arranged on Ribbed Bar arranged outside inner sleeve and outer sleeve, the problem of having avoided like this exposing in prior art the thread segment of half cover tube length, has guaranteed intensity, and simple installation.
Further, in the utility model, inner sleeve is divided into two parts vertically, can make like this inner sleeve, outer sleeve install, guaranteed strength and speed of application simultaneously.The thickness of lengthening section is less than the thickness of inner sleeve, and is less than the thickness near thread segment away from the thickness of thread segment.Facilitate like this installation of outer sleeve, also facilitate the installation between inner sleeve and reinforcing bar.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of half inner sleeve.
Fig. 3 is the structural representation of outer sleeve.
In figure: 1-outer sleeve; 2-inner sleeve; 3-top Ribbed Bar, 4-bottom Ribbed Bar, 5-tied silk.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As Figure 1-3, the utility model comprises Ribbed Bar and is sleeved on successively inner sleeve 2 and the threaded outer sleeve 1 of inner wall belt in Ribbed Bar outside, on the outer wall of outer sleeve 1, be provided with for spanner card and groove.Wherein, Ribbed Bar comprises top Ribbed Bar 3 and bottom Ribbed Bar 4; Inner sleeve comprises thread segment and the lengthening section that is arranged at thread segment two ends, and the thickness of lengthening section is less than the thickness of inner sleeve, and is less than the thickness near thread segment away from the thickness of thread segment.Described inner sleeve is divided into two parts vertically, offers annular groove on two parts, is provided with the tied silk 5 that two parts is fixed to connection in annular groove.
Thread segment inwall is provided with the screw thread that matches with the screw thread in Ribbed Bar, is provided with the screw thread that the screw thread of outer sleeve 1 matches on thread segment outer wall.
When the utility model work, first allow top Ribbed Bar 3 and the bottom Ribbed Bar 4 of descending reinforcing cage align, after reinforcing cage aligns, the top Ribbed Bar 3 that many people align with inner sleeve 2 simultaneously and the junction of bottom Ribbed Bar 4 wrap, adopt tied silk 5 that two and half sleeves are fixed simultaneously, then with the groove that spanner blocks on outer sleeve, outer sleeve is screwed on, until the thread segment of outer sleeve and the thread segment of inner sleeve all coordinate.
Specific works process is that inner sleeve is arranged in threaded Ribbed Bar, and inner sleeve 2, along being circumferentially cut into two half blocks, when two half block inner sleeves are embraced after upper and lower two reinforcing bars, then is installed to outer sleeve on inner sleeve.In bridge pier column reinforcing cage installation process, to be installed by several staff simultaneously, inner sleeve is except normal thread segment, two ends also have lengthening section, lengthening section thickness is less than the thickness of inner sleeve, and is less than the thickness near thread segment away from the thickness of thread segment, the convenient like this outer sleeve 1 of installing.
More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model all belongs to protection domain of the present utility model.
