The utility model discloses one kind three across prefabricated building cover board, it is the building cover board being prefabricated into by armored concrete, some hollow-core constructions are provided with the building cover board, the building cover board is provided with the preformed hole passed through for pillar reinforcing bar, and the building cover board periphery is provided with the protruding bar on the outside of stretching out.The utility model three saves material across being provided with some hollow-core constructions in prefabricated building cover board, building cover board, reduces cost, conducts oneself with dignity small, it is possible to increase its span；Building cover board is provided with four preformed holes passed through for pillar reinforcing bar, and superstructure span of slab is more, and seam is few, installs simple rapid, overall performance is good, and required building cover board splicing quantity is few during installation, reduces the engineering time, improves operating efficiency.
Description
Technical field
The utility model is related to building field, and specifically one kind three is across prefabricated building cover board.
Background technology
Floor framing plate is horizontally oriented structural bearing component, and all kinds of load transmissions that will act on flooring are to beam column etc.
Vertical supporting member, while each vertical load-carrying members also are connected into an entirety, therefore plays an important roll in structure entirety.
Current building cover board is frequently with superposed floor, a kind of structure shape that superposed floor is prefabricated and cast-in-place concrete is combined
Formula, superposed floor is combined into an entirety, cooperation with top cast-in-place concrete layer.But secondary casting concrete binder course
Quality does not reach one-time-concreting effect, with easy layering, cracking, the shortcomings of cast-in-place concrete amount is greatly and situ wet operation amount is more.
Prefabricated building cover board is mostly solid building cover board in the prior art, and consumable material is more, from great, significantly limit across
Degree；Also there is precast hollow building cover board in the prior art, conduct oneself with dignity small, span is big, but span is few, needs polylith building cover board to enter during installation
Row splicing is installed, and installs cumbersome, seam is more, and overall performance is poor, and often, the engineering time is long for building cover board lifting during installation, work
Efficiency is low.
Utility model content
Technical problem to be solved in the utility model is to provide one kind three across prefabricated building cover board, to overcome in the prior art
The easy layering of superposed floor, cracking, cast-in-place concrete amount are big, and the consumable material of prefabricated solid building cover board is big, from great, limit building
Cover plate span, the span of precast hollow building cover board is few, installs cumbersome, seam is more, and overall performance is poor, building cover board lifting time during installation
Number is more, the problems such as engineering time length and inefficiency.
The utility model solves the technical scheme that its technical problem used：One kind three across prefabricated building cover board, it be by
Some hollow-core constructions are provided with the building cover board that armored concrete is prefabricated into, the building cover board, the building cover board is provided with and supplies pillar
The preformed hole that reinforcing bar is passed through, the building cover board periphery is provided with the protruding bar on the outside of stretching out.
The hollow-core construction is located in the screen frame area of two layers of assembling reinforcement net formation up and down, and the hollow-core construction can be pros
Body, cuboid or other gengons structure.
The hollow-core construction is linearly distributed, and the position on the horizontal and vertical line of the preformed hole is avoided in its distribution.
Four preformed holes are distributed with the building cover board transverse direction, and retain original superstructure slab in the preformed hole
Muscle.
The protruding bar is that the building cover board reinforcing bar stretches out, and its extension meets wanting for bar connecting length
Ask.
Using the utility model three across prefabricated building cover board, building cover board is integral prefabricated, and cast-in-place amount is few, rigidity is big；In building cover board
Provided with some hollow-core constructions, material is saved, cost is reduced, conducted oneself with dignity small, it is possible to increase its span；Building cover board supplies pillar provided with four
The preformed hole that reinforcing bar is passed through, superstructure span of slab is more, and seam is few, installs simple, overall performance is good, required building cover board splicing during installation
Quantity is few, reduces the engineering time, improves operating efficiency.

Embodiment
The structure to the utility model three across prefabricated building cover board is further described below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, the utility model three is the building cover board being prefabricated into by armored concrete across prefabricated building cover board,
Including some hollow-core constructions 2, preformed hole 4, two layers of net distribution up and down building cover board reinforcing bar 3 and building cover board periphery protruding bar 5.
As shown in Figure 1, Figure 2 and Figure 3, some hollow-core constructions 2 are provided with the building cover board 1, the building cover board 1 is provided with confession
The preformed hole 4 that pillar reinforcing bar 7 is passed through, the periphery of building cover board 1 is provided with the protruding bar 5 on the outside of stretching out.The hollow-core construction 2
In in the screen frame area of two layers assembling reinforcement net formation up and down, the hollow-core construction 2 can be for square, cuboid or other are polygon
Body structure；The hollow-core construction 2 is linearly distributed, and the position on the horizontal and vertical line of the preformed hole 4 is avoided in its distribution；Institute
State and four preformed holes 4 are distributed with the transverse direction of building cover board 1, and retain original building cover board reinforcing bar 3 in the preformed hole 4；Institute
Protruding bar 5 is stated for the building cover board reinforcing bar 3 to stretch out, and its extension meets the requirement of bar connecting length.
During installation, superstructure plate support is set up, lifting building cover board passes through pillar reinforcing bar to the top of support member and pillar
Preformed hole on building cover board, adjusts superstructure plate support, to ensure that the degree of being mutually perpendicular to of building cover board and pillar reaches installation requirement, building
Seam is left between cover plate, is connected building cover board protruding bar, is finally connect in building cover board preformed hole and building cover board in seam crossing
Full concrete is poured at seam.
The utility model three is provided with some hollow-core constructions across prefabricated building cover board, building cover board, saves material, reduces cost, subtract
Small deadweight, convenient lifting；Retain original building cover board reinforcing bar in building cover board preformed hole, improve its ability for bearing load；Superstructure
Span of slab is more, reduces building cover board lifting number of times and installs seam, and shortening engineering time, raising operating efficiency, overall performance are good.
