It is connected between word secondary beam by connecting pawl, principle is that two pawl heads are hooked on the edge of a wing of carpenter's word secondary beam, another sawtooth hooks card
On the edge of a wing of carpenter's word secondary beam, by tightening bolt linking together between carpenter's word secondary beam and carpenter's word secondary beam, closely
Fitting, does not stay gap, and carpenter's word secondary beam is made to form entirety, common stress with carpenter's word secondary beam.The inclined-plane row of plain form lower part
Frame is using high capacity, the novel discs buckle frame that rigidity is big, stability is strong, and the top of disk buckle frame is using jacking come support inclined-plane master
Beam.Conversion stress is carried out with the slope wedge block for meeting bevel angle between jacking and inclined-plane girder, increases the contact of inclined-plane girder
Area, the bottom of slope wedge block is equipped with protrusion part, jacking edge is blocked using the protrusion part, to resist horizontal direction point
Power.
The construction method on high-supported formwork low-angle clear water inclined-plane of the present invention mainly includes the following steps：
S001：Set up inclined-plane framed bent, including installing supported rod erecting, between supported rod erecting connecting rod structure and in support
The top setting jacking of upright bar.
Clear water inclined-plane according to clear water is divided in advance and is required, plain form is cut with accurate template cutter, after cutting
It is accordingly numbered, when construction sits in the right seat according to drawing；
Inclined-plane framed bent uses disk buckle frame, and disk buckle frame is set up constructs in strict accordance with the high-formwork construction scheme of evaluation, first
Line setting is set up according still further to the position line on ground.
The overall stability for resisting the horizontal loading of slope bearing layer to strengthen the disk buckle frame below high-supported formwork inclined-plane, is being molded
Lower stabilizer wall to disk buckle frame do even wall drawknot.
Disk buckle frame need to be in the middle part of clear water inclined plate and top position setting reliably connects wall measure, and the jacking at the top of supported rod erecting is stretched
Go out section and reserve 200mm~350mm, girt is laterally set, oblique drawbar, oblique drawbar and inclined plate top are set along inclined-plane
Even wall steel pipe drawknot forms the steel pipe rack along inclined-plane, and oblique drawbar is connect with fastener at the top of inclined plate, for being difficult to junction
Then add vertical steel pipe.Middle part connects wall steel pipe across disk buckle frame two across every two across arrangement, steel pipe is close proximity to the main section of disk buckle frame
Point position, no more than 200mm.
S002：In installing inclined-plane girder on jacking, card sets slope wedge block between jacking and inclined-plane girder.
Inclined-plane girder uses Two bors d's oeuveres 10# channel steels, and gap is 50mm between two channel steels, and two channel steels pass through 6mm steel disc spacing 1m
It is welded to connect.
It is stoppered between jacking with slope wedge block at the top of inclined-plane girder and disk buckle frame, it with sectional dimension is 40mm that slope wedge block, which is,
× 100mm wall thickness is cut for 3mm steel pipes, and the small steel discs of 3mm are welded in slope wedge block bottom, for blocking the edge of jacking,
The horizontal loading that slope bearing layer generates is resisted, jacking edge is blocked in slope wedge block lower part, has resisted the level that inclined-plane girder transmits
Power so that slope wedge block does not slide.During slope bearing layer, under the action of construction loads, slope wedge block can be under the action of load
More wedge is tighter, and the principle of wedge-shaped stress is utilized well, has been effective against horizontal loading.
S003：By connecting pawl in installation back cord structure on inclined-plane girder.
Back cord structure is positioned over tiltedly using the larger wooden H-beam of rigidity, wooden H-beam according to the distance no more than 300mm
On the girder of face, inclined-plane girder is closely connected with wooden H-beam by connecting pawl.
S004：In installing plain form in back cord structure.
Plain form uses 18mm thickness clear water plank sheathings, ensures there is wooden H-beam below plain form splicing seams, i.e., each
There is the support of wooden H-beam in clear water cicada seam lower section, can effectively prevent the faulting of slab ends of plain form, the dehydration of plain form piece is avoided to leak
Slurry, it is ensured that the effect of last clear water cicada seam；
The angle of inclined-plane girder is adjusted by jacking height at the top of the supported rod erecting of adjustment disk buckle frame, and then adjusts clear water mould
The angle of plate, when angular adjustment, are convenient and efficient.
Plain form is laid on wooden H-beam, plain form is nailed with wooden H-beam by front to be connected with wooden H-beam
It connects, hole for nailing poly-putty base equating, artificial jam-packed when plain form splices, and glass cement is beaten in the edge joint position of plain form, prevent
Only plain form piece dehydration spillage.
S005：In binding inclined-plane reinforcing bar on plain form.
In lower section pad three-ply board protection plain form when binding inclined-plane reinforcing bar.
Because slope bearing layer is single side formwork, trickle when slope concrete pours readily along inclined-plane, it is difficult to inclined-plane is formed,
Therefore the measure that steel wire is taken to block on inclined-plane is needed, when binding inclined-plane reinforcing bar, exist along the trickling direction of slope concrete
Interval binding multiple tracks steel wire block 22 on inclined-plane reinforcing bar 21, as shown in Figure 6.
S006：In pouring slope concrete on inclined-plane reinforcing bar.
It after the completion of inclined-plane reinforcing bar binding, carries out slope concrete and pours and vibrate, slope concrete molding is using steel wire
Block.
Low-angle clear water inclined-plane uses the form of one side formwork, only sets bed die, slump is excessive, flows
Dropping down property is big, therefore uses the smaller concrete of slump to facilitate molding, and slump is controlled in 140mm~160mm.
After the completion of slope concrete pours, because upper surface is without template, therefore covered rearing with plastic film maintenance can be used, maintenance is extremely
It is convenient.
Connection in the formwork reinforcement system of the present invention such as connects pawl, slope wedge block, is factory's regularization product, tears open
Except conveniently, easy to operate, dismounting is efficient.
Low-angle clear water inclined plate post-cast strip way using the present invention can obtain good effect, complete inclined plate well
The construction difficult problem of clear water, the method is efficient, and bearing capacity is big, and clear water effect is easy to ensure, is the method being worth in the same way.
The present invention is described in detail above in association with accompanying drawings and embodiments, those skilled in the art can basis
Above description makes the present invention many variations example.Thus, certain details in embodiment should not form limitation of the invention,
The present invention will be using the range that the appended claims define as protection scope of the present invention.
