Abstract
The invention provides a simple steel pipe bracket for an inner die of a box girder. The simple steel pipe bracket for the inner die of the box girder comprises a lead screw; supporting adjusting seats are arranged at two ends of the lead screw; each supporting adjusting seat comprises a fixing sleeve and a fixing pipe; one end of each fixing sleeve is matched and connected with the lead screw by threads; a circle of convex ring is arranged on the inner wall of the other end of each fixing sleeve; a circle of chute is formed in the outer wall of the end part of each fixing pipe; the convex rings of the fixing sleeves are in match with the chutes. When in use, the fixing sleeves are rotated, the length of the lead screw, exposed from the fixing sleeves can be adjusted, and thus the length of the simple steel pipe bracket for the inner die of the box girder can be adjusted; the mode of individually adjusting the lead screw to reinforce the inner die during mounting the inner die of the traditional box girder at the field can be avoided; the adjusting is convenient and quick; both time and force can be saved; the working efficiency can be increased; the processing cost is reduced; the other end of each fixing pipe is connected with a connecting plate; the connecting plates are connected with jacking devices through rotating shafts; therefore, the simple steel pipe bracket for the inner die of the box girder can cling to an inner die plate of the box girder, and as a result, the force on the inner die plate of the box girder is uniform.
Description
Technical field
The present invention relates to a kind of support, specifically a kind of simple and easy box girder inner formwork steel pipe support.
Background technology
In the relevant operations such as roadbed, bridges and culverts, cast-in-situ box girder, ballasted track, integrated ground, cable trench, mast foundation for overhead contact wire system, sound barrier, temporary project and cooperation ancillary works, need to use box girder inner formwork to adopt leading screw as support, box girder inner formwork template is reinforced, install because box girder inner formwork adds the segmented processing of solid model at every turn, when installing at the scene, the distance of leading screw support shuttering not etc., does not all need adjusting screw to reinforce internal mold at every turn, time-consumingly take a lot of work, cost is higher.
Summary of the invention
The object of this invention is to provide a kind of simple and easy box girder inner formwork steel pipe support, can solve the problem.
The present invention for achieving the above object, be achieved through the following technical solutions: comprise screw mandrel, the two ends of screw mandrel arrange support adjustment seat, support adjustment seat and comprise fixed muffle, stationary pipes, fixed muffle one end and wire rod thread are connected, the inwall of the fixed muffle other end is arranged a circle bulge loop, the outer wall of the end of stationary pipes arranges a circle chute, the bulge loop of fixed muffle and coordinating of chute.
In order to realize object of the present invention further, can also by the following technical solutions: the other end of stationary pipes connects junction plate, the hinged jacking of junction plate.Described screw mandrel periphery arranges sheath.Described jacking end arranges protection pad.
The invention has the advantages that: during use, rotate fixed muffle, regulate screw mandrel to expose the length of fixed muffle, thus regulate the length of simple and easy box girder inner formwork steel pipe support.Avoid independent adjusting screw in traditional box girder inner formwork field-mounted process to reinforce the mode of internal mold, fast easy to adjust, time saving and energy saving quickening operating efficiency, saves processing cost.The other end of stationary pipes connects junction plate, and junction plate connects jacking by rotating shaft, makes simple and easy box girder inner formwork steel pipe support more fit tightly box girder inner formwork template, make box girder inner formwork template stressed evenly.Screw mandrel arranged outside sheath, making operating personnel when rotating fixed block, can catch sheath, screw mandrel is not rotated with the rotation of fixed block.Meanwhile, the hand of sheath protection operating personnel preserves from, and avoids the wearing and tearing grasped for a long time hand.Jacking arranged outside protection pad, increases the contact area of jacking and beam inside molding plate, makes beam inside molding plate not be damaged in use procedure further.The present invention also has advantage compact, cheap for manufacturing cost and easy to use simple for structure.
Accompanying drawing illustrates: Fig. 1 is structural representation of the present invention, and Fig. 2 is the I partial enlargement structural representation of Fig. 1.

Detailed description of the invention
Simple and easy box girder inner formwork steel pipe support, as depicted in figs. 1 and 2, comprise screw mandrel 5, the two ends of screw mandrel 5 arrange support adjustment seat, support adjustment seat and comprise fixed muffle 6, stationary pipes 4, fixed muffle 6 one end is connected with screw mandrel 5 threaded engagement, the inwall of fixed muffle 6 other end is arranged a circle bulge loop 8, the outer wall of the end of stationary pipes 4 arranges a circle chute 9, the bulge loop 8 of fixed muffle 6 and coordinating of chute 9.The present invention arranges support adjustment seat by the two ends of screw mandrel 5, support adjustment seat and comprise fixed muffle 6, stationary pipes 4, fixed muffle 6 one end is connected with screw mandrel 5 threaded engagement, the inwall of fixed muffle 6 other end is arranged a circle bulge loop 8, the outer wall of the end of stationary pipes 4 arranges a circle chute 9, and the bulge loop 8 of fixed muffle 6 and coordinating of chute 9, only need rotate fixed muffle 6 during use, just screw mandrel can be regulated to expose the length of fixed muffle 6, thus regulate the length of simple and easy box girder inner formwork steel pipe support.When eliminating traditional box girder inner formwork in-site installation, the distance of leading screw support shuttering not etc., does not all need adjusting screw to reinforce internal mold at every turn.Save processing cost.The other end fixed connecting plate 3 of stationary pipes 4, junction plate 3 by rotating shaft connect jacking 2, make simple and easy box girder inner formwork steel pipe support more fit tightly box girder inner formwork template, make box girder inner formwork template stressed evenly.Screw mandrel 5 periphery arranges sheath 7, making operating personnel when rotating fixed block, can catch sheath 7, screw mandrel 5 is not rotated with the rotation of fixed block 6.Meanwhile, sheath 7 protects the hand of operating personnel to preserve from, and avoids the wearing and tearing grasped for a long time hand.Jacking 2 arranged outside protection pad 1, increases the contact area of jacking and beam inside molding plate, makes beam inside molding plate injury-free in use procedure further.
Technical scheme of the present invention is not restricted in the scope of embodiment of the present invention.The technology contents of the not detailed description of the present invention is known technology.
