Description
Technical field
The present invention relates to municipal technical field of bridge construction, the arrangement for adjusting height of more particularly to a kind of falsework and its
Application method.
Background technology
Falsework is typically made up of components such as column, crossbeams, and it is widely used in municipal bridge construction, can be as existing
Pour main load-carrying construction of beam, Coping Construction etc..
Because the top rake of bridge changes, the scaffolding height of each falsework is all inconsistent in construction, and falsework
Scaffolding height is limited by column specification and crossbeam specification, it is difficult to the disposable absolute altitude set up required for construction.Such as Fig. 1 and
Shown in Fig. 2, at present, the adjusting method of falsework scaffolding height is as follows：When setting up falsework 10, using " just it is low not
The principle of height ", the i.e. scaffolding height of falsework 10 are less than the absolute altitude needed for construction；Then, in the crossbeam 12 of falsework 10
Upper welding steel buttress 14 or absolute altitude of the billet 13 to be adjusted to needed for construction of jumping a queue；Finally, when bridge falls frame, steel branch is cut off
Pier 14.It can be seen that, the construction method needs to aid in falsework 10 to reach regulation height by welding and cutting off steel buttress 14
Purpose, not only degree of regulation is poor, and work high above the ground work amount in job site is big, need to expend substantial amounts of artificial.
The content of the invention
For the adjusting method of existing falsework height, degree of regulation is poor, and job site work high above the ground work amount
Big the problem of, it is an object of the invention to provide a kind of arrangement for adjusting height of falsework and its application method, with reference to regulation
The absolute altitude main regulation of bar and the fine setting of regulating bolt, and then the accurate absolute altitude for adjusting falsework, and without overhead welding operation,
Ensure construction safety and improve efficiency of construction.
The technical solution adopted for the present invention to solve the technical problems is：A kind of arrangement for adjusting height bag of falsework
Include：It is oppositely arranged and is connected to a pair of adjusting parts of the crossbeam of falsework；The adjusting part includes a L bracket, institute
The horizontal part for stating L bracket is fixed in the crossbeam, and the vertical portion of the L bracket is away from the crossbeam；A pair of hanging pieces, it is described
Hanging piece includes the hanging piece main body provided with U-shaped neck and connecting portion, and a regulating bolt, and the U-shaped neck is snapped in the L-shaped branch
The vertical portion of frame, the top of the U-shaped neck is threadedly coupled provided with bolt hole and with the regulating bolt, the regulating bolt
Top of the bottom then with the vertical portion of the L bracket offsets；And the adjusting rod between hanging piece described in a pair is arranged at, it is described
Vertically arranged some bolts hole on adjusting rod, and the adjusting rod and the connecting portion bolt connection of the hanging piece main body.
It is preferred that, the connecting portion of the hanging piece main body is the L-shaped steel member in a cross section, and one of the connecting portion is straight
Side and the U-shaped neck bolt connection, another straight flange of the connecting portion are connected with the adjusting rod by split bolt.
It is preferred that, the connecting portion of the hanging piece main body is steel member of the cross section in I shapes, the connecting portion and the U
Shape neck is vertical and fixes as one, on the connecting portion vertically arranged some bolts hole and with the adjusting rod bolt connection.
It is preferred that, the adjusting rod is made up of the steel with square-section.
It is preferred that, the adjusting rod is made up of square tube.
In addition, present invention also offers a kind of application method of the arrangement for adjusting height of falsework, step is as follows：
First, assembled height adjusting means and L bracket is fixed on the crossbeam of falsework in advance, lifts by crane the crossbeam
And the arrangement for adjusting height, by the crossbeam on the column of the falsework；
2nd, mobile adjusting rod carries out the main regulation of absolute altitude, makes the adjusting rod and the bolt on the connecting portion of hanging piece main body
Hole is alignd, and the adjusting rod is anchored on into the hanging piece main body by split bolt；
3rd, the height of the adjusting rod is finely adjusted by adjusting regulating bolt, the adjusting rod is adjusted to bridge
Absolute altitude needed for construction；
4th, the horizontal member of bridge is erected on the adjusting rod, when bridge falls frame, adjusts the regulating bolt, make
The horizontal member for obtaining the arrangement for adjusting height and the bridge departs from, and then removes the arrangement for adjusting height.
Effect of the invention is that：
First, the arrangement for adjusting height of falsework of the invention, including the L-shaped branch being installed on the crossbeam of falsework
Frame, is snapped in the hanging piece in L bracket, and with the bolted adjusting rod of hanging piece, vertically arranged some spiral shells on adjusting rod
Keyhole is easy to its absolute altitude of flexible modulation, further, is threadedly coupled by tightening (or unscrewing) with the U-shaped neck of hanging piece main body
Regulating bolt, is finely adjusted with realizing to the relative position between crossbeam and adjusting rod, so that falsework accurately be adjusted
To the absolute altitude needed for bridge construction.The present invention arrangement for adjusting height combination adjusting rod absolute altitude main regulation and regulating bolt it is micro-
Adjust, and then the absolute altitude of accurate adjustment falsework, and without overhead welding operation, when bridge falls frame, also eliminate on-site cutting
The work such as steel branch upsetting, have ensured construction safety and have improved efficiency of construction.
2nd, the application method of the arrangement for adjusting height of falsework of the invention, is in advance adjusted the height being completed
The L bracket of device is welded on the crossbeam of falsework, arrangement for adjusting height is lifted with crossbeam and is arranged on interim
On the column of support, the absolute altitude of the Level Change falsework for the adjusting rod being connected to by adjustment bolt on hanging piece is especially weighed
Want, the regulating bolt being also threadedly coupled by tightening (or unscrewing) with hanging piece is finely adjusted to the absolute altitude of falsework, from
And falsework is accurately adjusted to the absolute altitude needed for bridge construction, moreover, avoiding overhead welding operation, improve construction
Efficiency.
