Description

Movable prefabricated girder tensioning protector
Technical field
The utility model relates to bridge precast beam construction field, is specifically related to a kind of to the safety device protected during precast beam stretch-draw.
Background technology
During bridge precast beam construction, after precast beam concrete reaches design strength, tackle it and carry out prestress wire stretch-draw.Usual employing jack and intermediate plate are to steel strand tension.Hurt sb.'s feelings for preventing steel strand, intermediate plate etc. from flying out during stretch-draw, Ying Zheng arranges baffle plate to stretch-draw direction and protects.During general construction be the steel plate that vertically arranges of employing one block as protected apron, steel plate bottom welding one base, is placed on just to the direction of stretch-draw.But such protected apron is due to the large mobile inconvenience of weight, and cross section being provided with some bundle prestressing force due to precast beam, during stretch-draw, jack will move to next place after the complete a branch of prestressing force of stretch-draw, and installing/dismounting jack is also very inconvenient, need at substantial manpower, efficiency of construction is low.
Summary of the invention
The purpose of this utility model is to provide a kind of movable prefabricated girder tensioning protector, can need mobile flexibly in use, thus save manpower, raise the efficiency according to scene.
For achieving the above object, the utility model is by the following technical solutions:
A kind of movable prefabricated girder tensioning protector, comprises a rectangle baffle plate vertically arranged, it is characterized in that: the rectangle wheel carrier that described baffle plate base welding one is vertical with baffle plane, and described wheel carrier arranges road wheel bottom four angles respectively; The rectangle support that described baffle plate top welding one is vertical with baffle plane, two limits that described support is vertical with baffle plate are respectively arranged with longitudinal rail, two longitudinal rail tops are provided with two cross slide waies vertical with longitudinal rail, and the two ends of two cross slide waies are respectively equipped with the longitudinal roller along described longitudinal rail movement; Described cross slide way top, is provided with the peg vertical with cross slide way, and the two ends of described peg are provided with the transverse-roller along described cross slide way movement, hang a Chain block in the middle part of described peg.
The beneficial effects of the utility model are:
(1), device conveniently moving.Bottom of device is installed can the wheel of multiple-directional rotating, only needs 1 people just whole device can be moved to next work plane.
(2), jack moves and easy installation and removal.Jack is hung by Chain block, by the chain sling on longitudinal direction, cross slide way and Chain block, can realize any movement of jack three dimensions, also greatly facilitate jack installing/dismounting.
(3), protection effect is remarkable.Baffle plate is provided with two layers, reaches beam slab stretch-draw safety protection standard.
(4), construction cost is reduced.Set of device can be recycled and reused for box girder tensioning and stretch-draw protection, transition can reuse to other building sites, is very suitable for the mobility feature in building site.
(5), save artificial and reduce labour intensity.The stretch-draw of equivalent amount beam slab needs 4-5 people, and adopts the utility model, and stretching process only needs 2 people.
Accompanying drawing explanation
Fig. 1 is the lateral view of a kind of embodiment of the utility model;
Fig. 2 is the front view of a kind of embodiment of the utility model;
Fig. 3 is the top view of a kind of embodiment of the utility model;
Fig. 4 is a kind of using state figure of the present utility model.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model comprises a rectangle baffle plate 1 vertically arranged, the rectangle wheel carrier 2 that described baffle plate 1 base welding one is vertical with baffle plane, and described wheel carrier arranges road wheel 3 bottom 2 four angles respectively; The rectangle support 4 that described baffle plate 1 top welding one is vertical with baffle plane, two limits that described support 4 is vertical with baffle plate 1 are respectively arranged with longitudinal rail 5, the two ends that two longitudinal rail 5 tops are provided with two cross slide way 6, two cross slide waies 6 vertical with longitudinal rail are respectively equipped with the longitudinal roller 7 along described longitudinal rail movement; Described cross slide way 6 top, is provided with the peg 8 vertical with cross slide way, and the two ends of described peg are provided with the transverse-roller 9 along described cross slide way movement, hangs a Chain block 10 in the middle part of described peg.
The utility model can move by the road wheel bottom wheel carrier, is convenient to move to next station from a station.Mobile more flexible for making, road wheel can be set to universal wheel during concrete enforcement.
For reaching better protection effect, baffle plate can be set to two-layer by the utility model, and first floor is bamboo slab rubber, plays cushioning effect, and the second layer is steel plate, has stopped steel strand, intermediate plate etc. and has penetrated baffle plate.
For making whole apparatus structure firm, wheel carrier fixed bar 11 can be welded between wheel carrier with baffle plate; Welding support fixed bar 12 between support and baffle plate.
As shown in Figure 4, the utility model in use, precast beam 13 place needing stretch-draw is first moved to by road wheel, jack 14 is hung by Chain block outstanding 10, operation Chain block jack is moved up and down, peg by transverse-roller transversely guide rail move, cross slide way by longitudinal roller longitudinally guide rail move, realize the position adjustments of jack three dimensions, jack is moved to prestress wire 15 place to be tensioned, be connected with steel strand and start stretch-draw; A branch of steel strand tension completes, and jack moves to next place more by the way.After a precast beam stretch-draw completes, promote whole device and move to next precast beam and carry out stretch-draw.
For making whole device in stretching process keep stable, two can be established to link up with 16 in the front end of support 4, be connected and fixed in hook 16 and precast beam 13 top during stretch-draw, anti-locking apparatus moves.
