Description
Technical field
The present invention relates to the building element used in a kind of construction, in particular it relates to a kind of cast-in-situ concrete member
In built-in fitting.
Background technology
It is built-in fitting is conventional in construction setting that the crab-bolt leg colligation of built-in fitting or point, which are welded in the cage bar of post, wall, beam,
Mode, for the construction method in the process of vibrating of concrete, the position of built-in fitting is easily by vibration displacement, it is difficult to ensures built-in fitting
The accuracy of position.Treat in installation afterwards, majority needs to be picked chisel afterwards, and picks the built-in fitting both out-of-flatnesses dug out and
Also it is lack of standardization, and most do not meet also designs coordinate position requirement, or even some also can not find, it is necessary to carry out bar planting or plant swollen
The modes such as swollen bolt are handled.The presentation quality of architectural engineering is so not only influenceed, seriously, structural strength is had an effect on, increases simultaneously
Add workload and waste of materials.
The content of the invention
The shortcomings that to overcome in the prior art, it is an object of the invention to provide in a kind of new cast-in-situ concrete member
Built-in fitting, the embedded part structure is simple, easy for installation, avoids the structure caused by built-in fitting displacement from destroying or need bar planting etc. to lack
Point.
To reach above-mentioned purpose, the present invention adopts the following technical scheme that：
Built-in fitting in cast-in-situ concrete member, including steel plate, crab-bolt and screw rod, crab-bolt are welded on the side of steel plate, spiral shell
Bar is welded on the opposite side of steel plate, and nut is carried on screw rod；
Preferably, steel plain size is 300mm × 300mm, thickness 10mm；
Preferably, spiro rod length 100mm；
Preferably, the quantity of screw rod is four, and the quantity of crab-bolt is four；
Preferably, screw rod uses φ 8- φ 12 shank of bolt, and nut uses the nut of respective model.
Built-in fitting in cast-in-situ concrete member of the present invention has advantages below：Applied using the built-in fitting of the present invention
Work, position accuracy rate, the project installation quality of built-in fitting have obtained comprehensive lifting, solve factory building, equipment installation and technique
Easily there is the common quality defect such as displacement, inaccurate in the built-in fitting such as pipeline coordinate, has good Social benefit and economic benefit.

Embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
As shown in Figure 1-2, the built-in fitting in cast-in-situ concrete member includes steel plate 1, crab-bolt 2 and screw rod 3, four crab-bolts 2
It is welded on a side of steel plate 1, four screw rods are welded on another side of steel plate 1, and nut 4 is carried on screw rod 3；Spiral shell
Bar uses φ 8- φ 12 shank of bolt and is furnished with corresponding nut；Steel plain size is 300mm × 300mm, thickness 10mm；
Spiro rod length is 100mm.
As shown in figure 3, when template 5 is installed, at Designing of Pre-embedded Pieces in Concrete Structures coordinate position, it is corresponding that electricity consumption is drilled in the face of template 1
Coordinate position on, drill out the hole more bigger than screw rod 3, then the screw rod 3 welded on built-in fitting and this hole to good, then
Nut 4 is tightened itself and screw rod with spanner at the back side of template, so as to which built-in fitting and template are fixedly secured, without with reinforcing bar
Frame 6 fixes, not the change of the position by framework of steel reinforcement 6 in cast and change, so as to ensure that the position of built-in fitting is accurate.
During form removal, only the mould outer nut 4 of built-in fitting need to be first screwed down, then carry out form removable；Treat form removable
Afterwards, nut 4 is screwed on screw rod 3 in time, protects screw rod effect without damage.
