Description
Technical field
The present invention relates to end mould design field, specially a kind of Long Span Continuous Rigid-Frame Structure is outstanding to fill Side Template location and installation
And the tooling and method removed.
Background technology
Appearance with railway parent company to continuous beam associated construction technique instruction, the construction quality of continuous beam is
It is obviously improved.The previous form using wooden model and steel plate processing Side Template cannot meet today's society to continuous beam
The requirement of construction quality.
Traditional end mould design the mode of trepanning directly in template be easy to cause under form removal construction efficiency, construction risk
It is higher, and template deformation seriously recycles number and puts into less greatly.
Invention content
In view of the above-mentioned problems, can greatly improve end mould positioning, installation the purpose of the present invention is to provide one kind and remove
Construction efficiency, save the construction time, reduce construction input, at the same make that beam body end construction quality effectively improves it is big across
Spend the outstanding tooling and method for filling Side Template location and installation and dismounting of continuous rigid frame.Technical solution is as follows：
A kind of outstanding tooling for filling Side Template location and installation and dismounting of Long Span Continuous Rigid-Frame Structure, includes being made of multiple template unit
Unjointed beam Side Template, the modular unit according to reinforcing bar reserving hole position be boundary divided comprising scale steel plate and
Fixed length angle steel；The wide open slot of reinforced hole is arranged on fixed length angle steel；Inside is scale steel plate without hole or less porous hole position.
Further, the scale steel plate is fixedly connected with fixed length angle steel by bar dowel.
A method of the outstanding filling Side Template location and installation of Long Span Continuous Rigid-Frame Structure and dismounting are carried out, is included the following steps：
Step 1：Scale steel plate and fixed length angle steel are cut according to the size of the modular unit divided by unjointed beam Side Template；
Step 2：The wide open slot of reinforced hole is opened up to fixed length angle steel, to being reserved with the scale steel plate trepanning of a small number of reinforcing bar holes；
Step 3：Fixed length angle steel is installed to the beam-ends line position of design, and is connect with bed die and side form spot welding；
Step 4：Installation scale steel plate penetrates longitudinal reinforcement using bar dowel by fixed length angle steel and scale Interal fixation；
Step 5：Reinforcement measure, casting concrete are taken to beam-ends template；
Step 6：When dismounting, the bar dowel of beam-ends template each section connection is removed, each modular unit is independently removed.
The beneficial effects of the invention are as follows：Emphasis considers the spy of reinforcing bar reserving hole when the present invention makes full use of end mould processing
End mould is divided into several units by point using reinforcing bar reserving hole channel position as boundary.The wide open slot of reinforced hole designs on fixed length angle steel,
Inside is designed as scale steel plate without hole or less porous hole position, steel plate is connect with angle steel using bar dowel spot welding, such design
It not only installs, reinforce conveniently, after the completion of concreting, striking time can reduce significantly, while this tooling reuses number
It is more, beam body end concrete is destroyed less.

Fig. 2 is fixed length angle steel fluting schematic diagram.
Fig. 3 is angle steel template scheme of installation.
Fig. 4 is that end head formwork combines scheme of installation.
In figure：1- beam-ends templates；2- modular units；3- fixed length angle steel；The wide open slot of 4- reinforced holes；5- scale steel plates；6- is vertical
To reinforcing bar；7- bar dowels.
Specific implementation mode
The present invention is described in further details in the following with reference to the drawings and specific embodiments.A kind of Long Span Continuous Rigid-Frame Structure is outstanding
Side Template location and installation and the tooling of dismounting are filled, includes the unjointed beam Side Template 1 being made of multiple template unit 2, the template
Unit 2 is that boundary is divided according to reinforcing bar reserving hole position.Modular unit 2 includes scale steel plate 5 and fixed length angle steel 3；Steel
Muscle hole fluting 4 is arranged on fixed length angle steel 3；Inside is scale steel plate 5 without hole or less porous hole position.Wherein, the scale
Steel plate 5 is fixedly connected with fixed length angle steel 3 by bar dowel 7.
Operation principle：The device takes full advantage of the principle that whole end head formwork is made of modular unit.Scale 5cm ×
5cm angle steel is slotted according to rebar design spacing, is not only the fixture of reinforcing bar positioning, while being also the standard apparatus of template assemblies.
Steel plate is welded with angle steel using bar dowel, and installing and dismounting speed is accelerated.It is not slotted using steel plate and is changed with beam body rebar sizes
Little feature carries out gas cutting using steel cutting equipment after form removable to steel plate, can quickly meet beam body web, top
The requirement of plate and bottom plate Varying-thickness, And of Varying Depth.
Specific construction method, includes the following steps：
Step 1：Scale steel plate 5 and fixed length angle steel 3 are cut according to the size of the modular unit 2 divided by unjointed beam Side Template 1.Beam
Side Template dividing elements are as shown in Figure 1.
Step 2：The wide open slot 4 of reinforced hole is opened up to fixed length angle steel 3, the scale steel plate 5 to being reserved with a small number of reinforcing bar holes is opened
Hole, the fixture as reinforcing bar positioning.Fixed length angle steel fluting is as shown in Figure 2.
Step 3：By the beam-ends line position of the installation of fixed length angle steel 3 to design, and it is connect with bed die and side form spot welding；Such as Fig. 3
It is shown.
Step 4：Scale steel plate 5 is installed, fixed length angle steel 3 and scale steel plate 5 are fixed using bar dowel 7, penetrate longitudinal steel
Muscle 6；As shown in Figure 4.
The fixed length angle steel formerly installed provides reference position for the assembling of scale steel plate, makes the assembling of scale steel plate more
It is convenient accurate.Scale steel plate is welded with fixed length angle steel using bar dowel 7, and installing and dismounting speed is accelerated.
Step 5：Reinforcement measure, casting concrete are taken to beam-ends template 1；
Step 6：When dismounting, the bar dowel 7 that 1 each section of beam-ends template connects is removed, each modular unit 2 is independent to be removed.Form removal
Time can reduce significantly, while this tooling is reused often, is destroyed to beam body end concrete less.
