Technical field
The present invention relates to concrete prefabricated interconnection technique field.
Background technology
Present board house or the Roofing slab of concrete prefabricated structure are usually that, using two kinds of forms, one kind is prefabricated in advance
With roof structure identical plate body, covered on roof when binding, this way is convenient and simple, but a disadvantage is that whole
Body effect is bad, is not sufficiently stable, and another form is to carry out integral cast-in-situ to floor to build, and this way can be good at ensureing
The resistance to overturning of floor, but the operation that operates is too complicated, labor intensive material resources, is also very big waste to material, it is whole
Body effect is not easy control, so now in order to solve the above problems, now providing a kind of precast roof slab node connecting structure
Preparation method.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of precast roof slab node connecting structure, the party
Method easy construction is feasible, construction precast construction has been reached the effect for making whole top board keep high integrity and stability.
To solve the above problems, the present invention adopts the technical scheme that a kind of making of precast roof slab node connecting structure
Method, the method is comprised the following steps,（1）The big little makings concrete-pouring template of the walls shape of caping, makes mould as needed
Plate is surrounded and is provided with frame-shaped construction, and template to the recessed U-bend in inner side；
（2）Reinforcing bar is laid in framework to template composition, and the reinforcing bar outside stretching out in template is provided with the U-bend and broken
Head；
（3）To casting concrete in pattern plate bolster body, until the upper surface of concrete flushes with the top surface of template, concrete is then treated
It is conserved after solidification, then the reinforcing bar broken end welding lock ring that will expose；
（4）Template framework is removed, the prefabricated top board that will be made is transported to the top of bearing wall, by two prefabricated top boards
Side lap and makes to leave certain space between two prefabricated top boards in the top surface of same bearing wall, makes long herein
Lock ring on degree direction is aligned；
（5）While being inserted through the reinforcing rod of all lock rings, Ran Hou on all lock rings that will be aligned on same length direction
Casting concrete in space between two prefabricated top boards.
Preferably, step（1）Middle concrete-pouring template is rectangle or square, and the concrete-pouring template is
Wooden square plate, the quantity of U-bend is at least three on single concrete-pouring template.
Preferably, the step（2）In stretch out in outside template reinforcing bar broken end length be 8 centimetres to 10 centimetres.
Preferably, the step（3）In lock ring be cyclic structure or tubular structure.
Preferably, the step（4）In between two prefabricated top boards the width in space be 5 centimetres to 15 centimetres.
Preferably, the step（5）Middle poured concrete is flush with the upper surface of prefabricated top board.
The beneficial effects of the present invention are the method effect is good, and operating process is easy, and the structure can either effectively keep
The globality and stability of whole top surface, serve good technique effect, and simple and convenient during operation, save
The inconvenience of one-piece casting is just carried out to whole top board, substantial amounts of material has been saved.
Brief description of the drawings
Fig. 1 is the structural representation of the precast roof slab node connecting structure obtained by invention；
Fig. 2 is that prefabricated top board is placed on structural representation on bearing wall in Fig. 1.
Specific embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：A kind of precast roof slab section
The preparation method of point attachment structure, the method is comprised the following steps,（1）The big little makings coagulation of the walls shape of caping as needed
Native formwork for placing, surrounds template and is provided with frame-shaped construction, and template to the recessed U-bend in inner side；Concrete-pouring template
It is rectangle or square, the concrete-pouring template is wooden square plate, U-bend on single concrete-pouring template
Quantity is at least three.
（2）Reinforcing bar is laid in framework to template composition, and the steel outside stretching out in template is provided with the U-bend
Breaking of muscle and tendon head；The length for stretching out in the reinforcing bar broken end outside template is 8 centimetres to 10 centimetres.
（3）To casting concrete in pattern plate bolster body, until the upper surface of concrete flushes with the top surface of template, then wait to mix
It is conserved after solidifying soil solidification, then the reinforcing bar broken end welding lock ring that will expose；
（4）Template framework is removed, the prefabricated top board that will be made is transported to the top of bearing wall, by two prefabricated top boards
Side lap and makes to leave certain space between two prefabricated top boards in the top surface of same bearing wall, makes long herein
Lock ring on degree direction is aligned；Lock ring is cyclic structure or tubular structure.The width in space is 5 between two prefabricated top boards
Centimetre to 15 centimetres.
（5）While being inserted through the reinforcing rod of all lock rings on all lock rings that will be aligned on same length direction, so
Casting concrete in space between two prefabricated top boards afterwards.The concrete for pouring is flush with the upper surface of prefabricated top board.
A kind of precast roof slab node connecting structure, the structure includes the multiple prefabricated top board on bearing wall, phase
Bindiny mechanism is provided between two adjacent prefabricated top boards, described prefabricated top board 2 is the concrete slab for pouring in advance, described
The reinforcing bar of booster action is provided with prefabricated top board, bindiny mechanism includes being provided with multiple U-shaped breach at the edges of boards of prefabricated top board,
The upper and lower surface for distinguishing the prefabricated top board of insertion up and down of U-shaped breach, two adjacent the two of prefabricated top board adjacent panels
U-shaped breach between side is oppositely arranged, and a reinforcing bar with lock ring is provided with each U-shaped breach and is breaked end, in same side plate
All lock rings in the same direction of side are aligned and are installed with and are adapted reinforcing rod, are also poured between two adjacent prefabricated top boards
There is concrete.
Prefabricated top board is rectangle or square, and the quantity of U-shaped breach is at least three on the unilateral prefabricated top board of edges of boards.
Lock ring is closed ring body.The relative edges of boards of two adjacent prefabricated top boards are overlapped on the top surface of same bearing wall.
The thickness of prefabricated unit top board is 5 centimetres to 10 centimetres, and the length of the prefabricated top board is 2 meters to 5 meters, and width is 1 meter to 4
Rice.
The device by split type prefabricated top board as building body or the top of room body, first by the prefabricated top board according to chi
It is very little prefabricated, framework is surrounded by template, reinforcing bar, that is, reinforcement are then laid in the frame, reach the journey arranged in length and breadth
Degree, then by maintenance aftershaping, with U-bend in template, so meeting forms U-shaped and lacks casting concrete when pouring
Mouthful, the prefabricated top board of each two is overlapped on a bearing wall top, reinforcing rod is then passed through, then between two prefabricated top boards
Space, that is, where reinforcing rod at by reinforcing rod, lock ring, pour together, its prefabricated top board with both sides is formed one
Individual overall structure, so just produces a desired effect.
The beneficial effects of the present invention are the method effect is good, and operating process is easy, and the structure can either effectively keep
The globality and stability of whole top surface, serve good technique effect, and simple and convenient during operation, save
The inconvenience of one-piece casting is just carried out to whole top board, substantial amounts of material has been saved.
