Description
Technical field
The present invention relates to construction and decoration field.
Background technology
Flourish along with modern architecture thing, large public building moulding is increasingly abundant, novel and diversified.Cause
This, in building engineering construction, the structure node difficulty of construction such as Curved beam cylinder becomes increasingly complex；Along with people are to engineering matter
Amount, the requirement of construction benefit improve constantly, and discuss research for Curved beam beam-cylinder joint difficulty of construction in irregular building: biography
System construction method takes fillet flat-die to make full fold-line-shaped spelling group along circular arc, then contains position with outside reinforcing bar annular anchor ear.Result goes out
Circle is lost in current situation portion, and outward appearance undulate, Forming Quality is poor.And make set shaped steel formwork specially, description can be caused many, complete
I.e. lose turnover after work to be worth and scrap, the most uneconomical." adjustable arc-shaped beam cylindrical node assembling clamp " construction makes
By movable fixture stationary nodes template, the number of turnover is many, and technical economic benefit is notable, node quality beautiful appearance.
Summary of the invention
It is an object of the present invention to provide a kind of adjustable arc-shaped beam cylindrical node assembling clamp construction method, should
Method includes step:
(1) preparation of construction: according to confiding a technological secret of site technology administrative staff, carries out the examination of adjustable assembling fixture scene
Spell；
(2) set Curved beam bed die, colligation Curved beam reinforcing bar, then install Curved beam two side template and assemble adjustable card
Tool；Technical staff's on-the-spot guidance checks that fixture screw rod is fixed, and carries out self-inspection through Quality Inspector, and the management of qualified rear tissue is checked and accepted, detection
At node, template clamping is firmly and the requirement such as perpendicularity, all checks complete after-pouring concrete；
(3) by node quality examination, sum up construction experience and lesson, improve arrangement and method for construction, and workman's every day
Before leaving offices, site operation person, Quality Inspector class monitor and group leader is led to check the node quality constructed the same day, carry out evaluating, analyze,
Learn from other's strong points to offset one's weaknesses, improve constantly operative skill, improve construction technology further；
(4) conscientiously construct by job specfication, job specfication is accomplished, and staff is a, strengthen the quality responsibility heart to workman and teach
Educate.Organizational technology director gives some short-term training to operating personnel, is then passed through examination on the spot, defective not appoints, and passes through
After above-mentioned measure, modal displacement, swollen mould, spillage phenomenon have been resolved；
(5) strengthen vibrating with small-sized plug-in type vibrating rod for the core space that Curved beam beam-cylinder joint reinforcing bar is intensive, stop
Leak the dead angle that shakes, it is ensured that the density of joint cores concrete and design strength；
(6) in order to ensure the quality of node area concrete, before Curved beam beam-cylinder joint concrete initial set, carry out secondary shake
Smash, i.e. vibrate again once before concrete initial set, the density of concrete at Curved beam beam-cylinder joint, reduces and shrinks, it is ensured that matter
Amount；
(7) concrete after pouring, should carry out covering and water seasoning in 12h, water foster after pouring shaping
The shortest time protected is 7d, irrigation amount number, concrete should be able to be kept to be in moisture state and to be advisable, use plastic sheeting maintenance
Concrete, its exposed surface should all cover tightly, and has condensation water in should keeping plastic sheeting；
(8) striking time and form removal method are controlled, it is ensured that the corner angle of concrete, surface are complete.Must not arrive striking time pine
The accessories such as moving platen bolt, in order to avoid affecting concrete quality and the integrality of surface corner angle, forbid during form removal firmly to pound, hard sledge；
(9) concrete curing is carried out at bean column node in time with plastic sheeting parcel after concrete form removal.
Another object of the present invention is to provide a kind of adjustable arc-shaped beam cylindrical node assembling clamp, it uses two
Being fabricated to arc after block 4mm thickness 100mm width steel plate overlap half, lap can regulate the width of beam section at bean column node
Degree, fixture lap uses the screw rod of ￠ 12 to fix；200mm width steel plate side is fixed with node template, and side is with to drawing spiral shell
Bar is fixed, and the bilateral symmetry of beam is arranged, and along length direction perforating hole on 200mm width steel plate；Outside two row's macropores are according to angle
45 ° of settings, spacing 50mm, inner side one row's aperture is arranged according to spacing 100mm, and it is because having along depth of beam direction that outside macropore is arranged
Being connected with node at the bottom of the beam of the discrepancy in elevation, fixture can arbitrarily adjust spacing on the macropore of outside.
It is an advantage of the current invention that: at Curved beam beam-cylinder joint, use " adjustable arc-shaped beam cylindrical node assembling clamp "
Construction is compared with common templates assembling construction process, and position of joints apparent size and quality are guaranteed, and decrease coagulation
The swollen mould of Tu Jiedianchu, displacement, improve work efficiency and construction quality；This engineering method has certain operability, wound property and is suitable for
Property, extensively can apply at complicated round building structure Curved beam beam-cylinder joint core space.
The construction at present invention bean column node position be applicable to large public building circular configuration or arcuate structure.
