Difference, the problems such as quality is low, overcome that prefabricated board " beard muscle " rapid wear, the occlusion of contiguous prefabricated plate be difficult, pin is not easy positioning and
The disadvantages of steel using amount is big, secondary casting concrete amount is big.
Its major advantage has:
(1) reasonable stress: the main primary structure member of prefabricated board tank-type connecting component is the otic placode of connector, and otic placode etc. replaces by force
Slab muscle does not weaken prefabricated board steel bar stress section, and only changing dispersed placement slab muscle is centralized arrangement steel ear plate.Secondly, connection
Part in groups, in pairs, be symmetrically arranged in prefabricated board ends, each connector is arranged in the center of plate height, and connector stress is closed
Reason bears the mutual pulling force of prefabricated board, will not generate additional bending moment because of arranged off-centre, cause to reverse.
It after prefabricated board lifting is in place, deducts prefabricated board and shelves width, there are also the installation spaces of 150mm or so, in addition to the company of inserting
For fitting pin to fix outside prefabricated board, installation of the space of the 150mm or so width simultaneously as back reinforcing bar, beam peg is empty
Between.Peg interlaced can be arranged with connector, will not be fought each other.After prefabricated board installation is fixed in place, back can be laid
Reinforcing bar (peg can be welded on beam in advance in factory), pours piece concrete between the prefabricated board of back, by left and right prefabricated board, beam three
Person is closely joined together, and realizes the globality of floor.
The prefabricated board tank-type connecting component Path of Force Transfer is clear, reasonable, does not change the force way of floor using the device, ties
The anti-seismic performance of structure system does not weaken, and structure is secure safely.
(2) production is simple: the main component connected between two prefabricated boards is tank-type connecting component and dowel, pin, structure
Part arranges compact, deft design.Cut profiled sheet, punching, welding fabrication can be used in tank-type connecting component, and die sinking can also be used
Cast molding；Dowel can be used common cold rolled reinforcing steel bar with ribs in engineering and make through end fusing, jumping-up and tapping, bolt anchor head
Bolt the conventional hexagonal bolt and nut that can be purchased in the market can be used；Pin is then that using common snap rivet and will follow closely
Foot cuts chamfering molding, or using Ribbed Bar cutting, fusing jumping-up, cutting chamfered.
When tank-type connecting component production quantity is less, tank-type connecting component can be used cut profiled sheet, punching, welding and
It can be cut with Ribbed Bar at, dowel, jumping-up, tapping molding (nut of bolt anchor head is purchased from market), rivet can be used general
Logical rivet cutting chamfering is formed.If production quantity is big, all components be can be mass, and can be opened casting, and processing technology is simpler
Just, machining accuracy is also more guaranteed, and prefabricated board tank-type connecting component production is simple, reliable in quality, use easy to spread.
(3) quick for installation: dowel is first inserted into groove profile company by the pre-buried tank-type connecting component before prefabricated board casting concrete respectively
In the vertical plate dowel hole of fitting, clamping screw anchor head, then in pairs, centrally pre-buried arrangement tank-type connecting component.Prefabricated board factory
It is transported to scene, the prefabricated board of beam two sides lifts in pairs, tank-type connecting component is pushed into the tank-type connecting component of contiguous prefabricated plate, is inserted into
Pin, i.e., completion prefabricated board is in place, fixed, and the mounting means of the prefabricated board tank-type connecting component is simple, quick, efficient, construction
Quality is guaranteed.
(4) storage is convenient: prefabricated board tank-type connecting component each section component is all using separate type way, and dowel, pin are equal
Can dismantle, in factory's built-in connection just be inserted into dowel, at the scene in place, regulation prefabricated board when just insertion pin, accessory
Can store, occupy little space respectively, store, transport it is all very convenient.
(5) cost is saved: since the main primary structure member of the tank-type connecting component of prefabricated board is the otic placode of tank-type connecting component, ear
The strong replacement slab muscle such as plate, does not weaken prefabricated board steel bar stress section, and only changing dispersed placement slab muscle is centralized arrangement steel ear plate.
Therefore it is compared with traditional cast-in-place concrete floor, increased steel using amount very little.And coagulation is commonly overlapped with existing assembled
Tulou plate is compared, and due to floor one-pass molding, steel content not will increase, or even there are also reduce.It is prior, because changing folded
The way of concrete floor is closed, new prefabricated board connection type is simple and direct, and it is easy for construction efficiently to save labour cost, and reduce existing
The building materials expense of field waste.Therefore, cost can be reduced using the prefabricated board, saves cost.
