Abstract
The utility model discloses a modular telescopic device. The modular telescopic device is characterized by comprising a supporting box, a cross beam limiting plate, a cross beam, a lower boundary beam support, an upper boundary beam support, an upper middle beam support, a lower middle beam support, a boundary beam, an anchor bar set, a displacement spring, a T-shaped frame and a middle beam. Selection of structural steel of the modular telescopic device is different from selection of middle beam structural steel and boundary beam structural steel of an ordinary telescopic device. The structural steel of the modular telescopic device is middle beam structural steel so that sealing of the end of the structural steel of the modular telescopic device can be facilitated, and the problem that specially-shaped structural steel cannot be pulled out after being embedded into concrete is avoided. A panel of the supporting box of the modular telescopic device is flush with the upper edge surface of the structural steel of the modular telescopic device and is connected with the supporting box through bolts. After the modular telescopic device is installed, the panel of the supporting box can be directly detached on the road, and then the telescopic device can be maintained. The structural steel of the modular telescopic device is manufactured in a segmented mode according to the lane width, the segments of the structural steel are connected through bolts, and therefore the modular telescopic device can independently go in and out with one lane as a unit and then is maintained and replaced. The anchor bar set is connected with the structural steel through bolts, and therefore the situation that the modular telescopic device cannot be pulled out due to the fact that the anchor bar set is embedded into concrete is avoided. Most structures of the modular telescopic device are connected through bolts, the modular structure of the telescopic deice is refined better, and therefore batch production and standardized production of the telescopic devices are facilitated.
Description
Technical field
The utility model relates to a kind of bridge module formula stretching device structure.
Background technology
Bridge extension joint refers to for adapting to bridge in the deformation requirements between two beam-ends or between beam-ends and abutment, guarantee the bridge floor transition of when distortion steadily simultaneously and at bridge at the bridge Accessory Members arranging between two beam-ends or between beam-ends and abutment.Conventional stretching device generally designs, produces by bridge lateral width, because each total width of bridge is not quite similar, causes the production of product to lack the advantage of large-scale production; , if stretching device is damaged in operation process, in the equal Transducers Embedded in Concrete of its critical piece, cannot trip out meanwhile, will increase greatly the difficulty of maintain and replace.Therefore research and develop a kind of modular stretching device structure and become very urgent demand.
Utility model content
The purpose of this utility model is to provide a kind of production and processing modularization, is convenient to the novel plug formula stretching device of maintain and replace.
The utility model is to realize like this, construct a kind of modular stretching device, it is characterized in that: include support box, crossbeam limiting plate, crossbeam, side bar lower support, side bar upper support, central sill upper support, central sill lower support, side bar, dowel group, displacement spring, T-shaped, central sill; Support box panel flushes with stretching device shaped steel top face, and with bolts, dowel group and side bar are with bolts, and wherein side bar, central sill are with bolts.
Central sill is supported on crossbeam by central sill upper support, and central sill lower support applies certain precompression to central sill upper support; Crossbeam is supported on support box base plate by side bar lower support, and applies certain precompression by side bar upper support, crossbeam limiting plate restriction crossbeam transverse shifting; Dowel bond pads is on side bar, and side bar welding is on support box, and after pouring concrete, support box, dowel group and side bar are anchored in concrete together, forms an entirety with bridge; Displacement spring is connected on T-shaped and central sill, and T-shaped is bolted on central sill.
The utility model has the advantage of: modular stretching device structure described in the utility model:
1, selecting of stretching device shaped steel: be different from selecting of general stretching device central sill shaped steel and side bar shaped steel, modular stretching device shaped steel is middle joist steel, so that the sealing of stretching device shaped steel end prevents from cannot tripping out after shape steel rolled stock from embedding concrete.
2, supported box design: modular stretching device supported box panel flushes with stretching device shaped steel top face, with bolts with support box, stretching device can directly unload support box panel after installing on road surface, and stretching device is keeped in repair.
3, shaped steel modularization: modular stretching device shaped steel is according to lane width sectional making, with bolts.Make stretching device take track as a unit independent body trips out, carry out maintain and replace.
4, dowel group design: dowel group and shaped steel are with bolts, makes the stretching device can be because not tripping out in dowel group Transducers Embedded in Concrete.
5, connected mode: the most of structure of modular stretching device is with bolts, makes the refinement more of stretching device modular construction, is convenient to stretching device mass, standardized production.

Fig. 4 is displacement control system schematic diagram
Wherein: 1, support box, 2, crossbeam limiting plate, 3, crossbeam, 4, side bar lower support, 5, side bar upper support, 6, central sill upper support, 7, central sill upper support, 8, side bar, 9, dowel group, 10, displacement spring, 11, T-shaped, 12, central sill.
The specific embodiment
Below in conjunction with accompanying drawing, 1-4 is elaborated to the utility model, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The purpose of this utility model is to provide a kind of production and processing modularization, is convenient to the novel plug formula stretching device of maintain and replace.This project will (the wide 3.75m in standard track) be carried out modularized design take track as unit, arrange the stretching device of a module in a track, be conducive to the mass production of product, can in the situation that only sealing a track, realize rapid-maintenance and change.
On road, vehicle flowrate and vehicular load distribute differently on each track, and in same track, the distribution of vehicular load also exists more concentrated situation, carries out modularized design take track as unit, and convenience is carried out to optimum design of structuresprogram to heavily loaded track and heavily loaded position.
As Figure 1-4, this modular stretching device includes: support box 1, crossbeam limiting plate 2, crossbeam 3, side bar lower support 4, side bar upper support 5, central sill upper support 6, central sill upper support 7, side bar 8, dowel group 9, displacement spring 10, T-shaped 11, central sill 12.
