Abstract

A precast beam steel bar hanger frame belongs to the bridge construction technical field, which is characterized in that the lower structural beams horizontally distributed in the hanger frame are longitudinally distributed and fixed with upper structural beams, the upper structure of the hanger frame is fixed with a stayed reinforce bars, several or tens of hooks are fixed on the lower structural beams via iron chains, the hooks and the iron chains are provided with line tightening devices therebetween. The precast beam steel bar hanger frame has the advantages that the utility model can hang objects at multipoint and adjust the force on the steel bar skeleton uniform via the line tightening devices, to effectively prevent the steel bar skeleton from deformation in hanging, the utility model can parallel process a plurality of operations, accelerate construction and save project cot.

Description

Precast beam reinforcing bar mast-up

Technical field

The utility model belongs to the bridge construction technical field.

Background technology

Background technology:

At present, along with the arrival of China Express Railway upsurge in construction.The construction criteria of passenger dedicated railway line and technical requirements are more much higher than general railway, and basic reason is because passenger dedicated railway line must guarantee that high-speed track has the high ride of lasting stability.Bridge is as the keystone configuration thing of railway line for passenger traffic, and comparing with the common railway bridge at the construction party mask has characteristics such as Bridge Sections is big, the beam body weight is big, construction requirement is tight.Just because of above characteristics, when construction, must guarantee the operation or work standard of each operation.And the built-in fitting on the railway line for passenger traffic beam body is more, must guarantee the accurate of reinforcement location during construction.Reinforcing bar usually produces bigger distortion when carrying out beam body framework of steel reinforcement lifting construction because the weight of reinforcing bar focuses on.Can not satisfy the construction criteria of railway line for passenger traffic.Causing has wasted great amount of manpower and material resources and has also caused simultaneously bigger economic loss.Existing construction method: be after the reinforcing bar canopy carries out the processing of framework of steel reinforcement, to lift, adopt the hoisting structure of interim assembly unit in the hoisting process.Its weak point is: carry out framework of steel reinforcement lifting discontinuity, force structure is non-adjustable, the bigger distortion of same generation during lifting operation.

Summary of the invention

The purpose of this utility model is:

A kind of precast beam reinforcing bar mast-up is provided, discontinuity when it has solved the framework of steel reinforcement lifting, force structure is non-adjustable, produces the problem of bigger distortion during lifting operation.

The technical solution of the utility model is:

On the mast-up understructure beam of laterally arranging, vertically arrange and be fixed with mast-up superstructure beam, have at mast-up superstructure internal fixation and tiltedly to draw reinforced rib, several distribute by iron chains to several ten suspension hooks and are fixed on the mast-up understructure beam, are provided with boomer between suspension hook and the iron chains.

The beneficial effects of the utility model are:

When lifting, carry out many suspension centre liftings, make framework of steel reinforcement stressed evenly, prevented that preferably framework of steel reinforcement is out of shape in hoisting process by regulating boomer; Make the multinomial operation can parallel working, accelerated construction speed, saved engineering cost.

Description of drawings

Fig. 1 is a reinforcing bar mast-up planar view;

Fig. 2 is a reinforcing bar mast-up skiagraph;

Fig. 3 is a reinforcing bar mast-up cross-sectional view;

Fig. 4 is a lifting top board reinforcing bar scheme drawing;

Fig. 5 is a lifting end web reinforcement scheme drawing.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1, 2, 3, the 1st, iron chains, the 2nd, strengthening rib, the 3rd, mast-up superstructure, the 4th, mast-up understructure, the 5th, boomer.

The reinforcing bar mast-up is welded by shaped steel and steel plate.

With the suspension ring that weld on the steel wire penetrating mast-up, gantry crane by steel rope with whole mast-up handling to framework of steel reinforcement top, iron chains end suspension hook on the mast-up is transferred to the reinforcing bar end face, hook reinforcing bar with suspension hook, and the connection between this place's reinforced steel (can adopt spot welding).After all being arranged in all suspension hooks on the framework of steel reinforcement, adjust iron chains length so that each iron chains is stressed evenly with boomer.By gantry crane framework of steel reinforcement is slowly hung and to send into mould.
