Description
Technical field
The present invention relates to a kind of bidirectional laminated slab plate side piece connecting structure and overlapping board construction methods, belong to architectural engineering
Field.
Background technique
Since last decade, Chinese society economy is fast-developing steadily, and construction industry high energy consumption issues are outstanding day by day, and government is to section
Can emission reduction, environmental protection requirement increasingly improve.Traditional concrete structure production method is mostly cast in situs, working strength
Height, labour intensive, operating condition are poor, long in time limit, energy waste is serious, material loss is serious, building waste is more, cause engineering
Of poor quality, environmental pollution weight, and building life and design grave fault.And the component of fabricated construction is most of pre- in factory
System, can effectively shorten the construction period and economize on resources, the energy while, improve stock utilization, reduce building waste discharge,
And it can avoid influence of the external environment to construction speed.
Shear Behavior of R. c. Laminated Slabs is generallyd use in the superstructure of China's assembly concrete residential architecture at present.Concrete is folded
Plywood is as a kind of laminated structure member, compared with prefabricated board, improves structure overall stiffness and anti-seismic performance, with Bars In Poured Concrete Slab phase
Be easy to control than, quality, it is easy for construction quickly, save that template, industrialization degree be high, environmental pollution is reduced.Concrete folding plate
The advantage of two sides is combined, and can satisfy the requirement of building industrialization, is the house demolition for having the potentiality that grow a lot.
According to " prefabricated concrete structure technical regulation " (JGJ1-2014) the 6.6.3 articles regulation, superimposed sheet presses one-way slabs
Shi Keyong separate type seam is designed, designs Shi Keyong monoblock type seam by two-way slab；The 6.6.6 articles regulation, bidirectional laminated slab are pre-
Making sheet side Reinforcement, which must be stretched out, to be welded in post-cast strip, overlaps connection, bending anchoring, and post-cast strip width is not preferably less than
200mm.However, in engineer application, above-mentioned bidirectional laminated slab prefabricated panel need the way of reserved protruding bar can bring as
Lower problem: (1) prefabricated board board bottom has stretching reinforcing bar, needs largely to manually adjust the positioning of reinforcement, it is difficult to realize automatic
Change continuous productive process, production efficiency is low；(2) prefabricated board side needs to carry out undisguised material roughening treatment, needs to consume a large amount of people
Work, it is not water-saving and will cause environmental pollution, do not meet the spirit of green construction；(3) since overlap joint reinforcing bar positioning is also easy to produce partially
Difference needs to manually adjust the position of reinforcing bar, increases difficulty of construction in actual installation；(4) it was waited in production, transport and lifting
Cheng Zhong, prefabricated board protruding bar is easy to produce safety problem, and is easy bending, is easy to produce quality problems.
" assembly concrete connecting node construction " (15G310-1) supplement gives the close spelling piece of bidirectional laminated slab (i.e.
Above-mentioned separate type seam) construction.But the separate type seam for being applied to unidirectional superimposed sheet is only directly applied to by this construction
On bidirectional laminated slab, solve the problems, such as that bidirectional laminated slab prefabricated panel needs brought by reserved protruding bar, however but band
Carry out new problem: (1) mechanical characteristic of bidirectional laminated slab is different from unidirectional superimposed sheet, directly uses close spelling piece, edge joint position
Steel bar stress position is excessively high, it is necessary to increase tension reinforcement dosage；(2) it to prevent the too fast development in edge joint position crack, and must spell
Increase other construction measures at seam, will increase material utilization amount, increases cost.
Summary of the invention
In order to overcome existing middle bidirectional laminated slab prefabricated panel plate side to stretch out the piece form of reinforcing bar and existing not stretch out
The piece form problem encountered of reinforcing bar, the present invention provides a kind of bidirectional laminated slab plate side piece connecting structure and superimposed sheet is applied
Work method can not only cancel the stretching reinforcing bar of prefabricated panel plate side, more can effectively improve superimposed sheet overall stiffness and
Intensity reduces the crack developing of edge joint position, promotes the integral working of superimposed sheet, and work progress is convenient and efficient.
The technical solution used to solve the technical problems of the present invention is that:
A kind of bidirectional laminated slab plate side piece connecting structure, plate side and the preformed hole of top surface including prefabricated panel is arranged in
Hole and arc connector, reserving hole is corresponding at two communicates and path is arc, and arc connector passes through reserving hole, and two
The side lock outside reserving hole is held, two pieces of prefabricated panels are closely connected.
The construction method of bidirectional laminated slab in the piece connecting structure of bidirectional laminated slab plate of the present invention side, comprising the following steps:
Step 1: the platform mould of bidirectional laminated slab prefabricated panel is made according to design requirement, prefabricated panel surrounding does not stretch out steel
Muscle, platform mould do not need to slot；
Step 2: prefabricated panel reinforcement is arranged according to design requirement；
Step 3: curved steel tube or hose being arranged in prefabricated panel plate side according to design requirement, fix its position, it is ensured that arc
Shape steel pipe or hose are in sealing state, and when casting concrete leaks into pipe without slurries；
Step 4: bidirectional laminated slab prefabricated panel concrete is poured and conserved, scene is transported to after passed examination, lifting is in place,
Arc connector is passed through to the reserving hole of corresponding two pieces of prefabricated panel plate sides, locking member and anchoring piece are installed in both ends；
Step 5: the pre-buried equipment pipe and top bars being laid in bidirectional laminated slab pour and smash poured in place concrete, most
End form is at bidirectional laminated slab.
Compared with prior art, a kind of bidirectional laminated slab plate side piece connecting structure of the invention and overlapping board construction method,
Firstly, since eliminating the stretching reinforcing bar of prefabricated panel plate side, therefore on the one hand reduce the production process of prefabricated components, demoulding
When more convenient and quicker, improve production efficiency；On the other hand the versatility for improving platform mould improves every group of platform mould utilization rate,
Reduce production cost；Furthermore since reinforcing bar is not stretched out in plate side, collision is also effectively reduced in installation component, saves and stretches
The adjustment of reinforcing bar out, construction quality is more secure, assembles also faster more efficient.Secondly, the present invention is real using arc connector
The piece mode now connected can effectively improve the overall stiffness and intensity of superimposed sheet, reduce the crack developing of edge joint position, mention
Rise the integral working of superimposed sheet；The piece mode also power transmission is clear, and simple structure is understandable, and work progress is convenient and efficient, and
To the professional of less demanding of construction worker, be conducive to promote on a large scale.
