Method.
Background technique
For a long time, Building Engineering Design is pursued practical, safety, economy, the principle of beauty and is carried out, with national economy
Development builds this particularity works and has become the sociometric technique level in one epoch of reflection and the load of cultural concept
Body.The vertical entire body hanging plate of architectural engineering alien invasion, with its unique decorative effect, won it is public like and accept, and
It is widely used in multilayer, high residential building field.The a part of alien invasion entire body hanging plate as main structure, presentation quality
Directly affect the total quality of engineering.Therefore the construction quality of vertical entire body hanging plate is proposed higher must ask.It is general
The vertical entire body Slate hanging construction of architectural engineering alien invasion dissipates the mold method for spelling bamboo slab rubber using scene, and not only construction efficiency is low, at
This is higher, and construction quality, duration cannot be guaranteed.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the present invention provides a kind of vertical entire body hanging plates of alien invasion to apply
Work method.
Technical solution: a kind of vertical entire body Slate hanging construction method of alien invasion includes the following steps: that arrangement and method for construction determines ---
--- --- reinforcing bar binding is installed with examination --- inspection of steel reinforcement bars, examination --- template, is tested for levelling, unwrapping wire for stencil design, processing
Receive --- concreting --- form removable --- concrete curing --- finished product protection --- upper layer construction;Wherein:
The reinforcing bar binding and examination:
(1) hanging plate vertical reinforcement is anchored in balcony coupling beam, and horizontal bar and main structure the sleeper anchoring of width direction connect
It connects, binding joint location is mutually staggered, and same jointing longitudinal stress muscle connector should meet the regulation of design and specification, when examination
Check that specification, spacing, the joint location of reinforcing bar, the lap of splice have to comply with design and code requirement;
(2) starter bar is corrected, guarantees vertical, control thickness of protection tier, it is ensured that effective depth of section;
(3) the split bolt position of large steel moulding plate is fixed position, to avoid bolt eyelet and reinforcing bar from clashing, template
The position of bolt hole, vertically arranged mark rod are first popped up before in place on the ground;Split bolt is encountered and when reinforcing bar is fought, by phase
Adjacent several placing of reinforcements carry out appropriate adjustment, but adjusting amplitude must be in specification allowed band, to ensure split bolt installation position
It sets;
(4) tied silk tail is pushed down inwards after tied silk has been tied up, to prevent tied silk exposed, concrete surface appearance point point is made to become rusty
Spot;
The template is installed, is checked and accepted:
1) it before template installation, in lower layer's hanging plate bullet horizontal line in place's suitable for reading, is stitched with portable cutting machine-cut 1cm, portion's hair will be sewed on
Stubble is cut, and 1cm wide 3mm thickness sandwich rubber band is pasted under line, prevents hanging plate from spillage, bad root phenomenon occurs;
2) template is in place: template uses the big punching block of all steel, and tower crane cooperation alleviates labor intensity;
