Abstract
The utility model relates to the pre-buried of securing member, especially screw built-in fitting.Its structural feature is, comprises annular base, and a plurality of column tubes on one of base center and base, between center column tube and column tube on base, has rib to be connected.Column tube is respectively as fixing hole and securing member embedded hole.By fixing hole, this product is fixed in the template that need to use screw point position, after floor completes fluid concrete, this screw built-in fitting completes with regard to pre-buried, and floor presents screw embedded hole, and for tightening up a screw, object is installed in hanging.Avoid redrilling in the future to cause damage to metope floor.The utility model science simple in structure, pre-buried easy, stretching resistance is strong, firmly.
Description
Technical field
The utility model relates to the pre-buried of securing member, especially screw built-in fitting.
Background technology
The house that finishing has been whitewashed, needs mounted lamp, hangs adapted tool etc., normally takes electric drill or hammering to get hole and installs.Like this floor or metope are caused to damage, be sometimes even corrupted to the pipeline being embedded in body of wall, cause wire short-circuiting, or the serious consequence such as Water pipe leaking.
Utility model content
The purpose of this utility model is to overcome prior art deficiency, and the screw being embedded in floor or body of wall built-in fitting is provided.In major structure of construction framework engineering, complete template formwork, before placing of concrete, on its template face screw point of application, bury this product.Can on the some position of screw, carry out pre-buriedly with being intended to estimate to use, reserve screw hole position, avoid destructive and install, for unnecessary no preformed hole, can whitewash to fill and lead up and leave no trace.
The purpose of this utility model realizes by following approach.
Screw built-in fitting, its structural feature is to comprise annular base, and a plurality of column tubes on one of base center and base, between center column tube and column tube on base, has rib to be connected.
Described base center column tube can be used as fixing hole, column tube on base is as securing member embedded hole, or the column tube of base center is as securing member embedded hole, and the column tube on base is as fixing hole, and the described column tube as fixing hole is spaghetti.
At building body floor concrete formwork, complete, while not carrying out casting and compacting of concrete, with reference to construction drawing, use on the some position of screw estimating, as lamp installation position, hang the positions such as adapted tool, screw built-in fitting is carried out pre-buried.Screw built-in fitting base is kept flat on template millet cake position, with member, by fixing hole, built-in fitting is fixed in template and is positioned, during disturbing concrete, it is embedded in concrete structure layer, pull down after formwork pre-buried completing.On floor face, just reserve securing member embedded hole.During use, be combined with usefulness, at embedded hole, screw in the securing members such as self-tapping screw, expansion bolt.
The utility model prioritization scheme is also:
Described fixing hole is logical heart cylindrical tube, the polygon prism pipe that securing member embedded hole is upper end closed.
Circular fixing hole facilitates the location of built-in fitting, only need through fixing hole, built-in fitting be followed closely on formwork with iron nail; Securing member embedded hole is polygon prism pipe, like this, has increased frictional force between securing member embedded hole and securing member, has also increased built-in fitting and concrete Contact face simultaneously, in securing member processes such as DRIVE SCREWSs, avoids skidding; When on embedded hole, end closure is avoided fluid concrete by embedded hole landfill.
Described base center column tube is as securing member embedded hole, and its caliber is reducing, and epimere caliber is greater than hypomere caliber.
Like this, column tube hypomere closes the more concrete of bag than epimere, and hypomere form to support epimere, when body is subject to pulling force, the epimere body application of force below concrete on, strengthened the stretching resistance of built-in fitting.While especially hanging weight on ceiling, use this built-in fitting can bear heavier object.
Described base is annulus or elliptical ring.
Like this, poured into a mould after concrete, concrete fills up ring internal pore, makes built-in fitting and concrete inlay to such an extent that more reinforce, and has very strong stretching resistance.
Column tube on described base is equally spaced, and makes embedded part structure stable.
In sum, the utility model is rational in infrastructure, and stretching resistance is strong, is embedded in advance in concrete floor, has solved while needing hung articles after house decoration flooring is caused to damage problem.
Accompanying drawing explanation
Fig. 1 is embodiment 1 structural representation
Fig. 2 is most preferred embodiment structural representation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The specific embodiment
Embodiment 1
As Fig. 1, screw built-in fitting, comprises built-in fitting annular base 1, and two pentagonal prism shape embedded holes 2 that are equally spaced on the circular spaghetti fixing hole 3 in one of base center and base, and fixing hole 2 has rib 4 to be connected with securing member embedded hole 3 interdigits.
At building body floor concrete formwork, complete, while not carrying out casting and compacting of concrete, with reference to construction drawing, on expectation use screw point position, carry out pre-buried.Screw built-in fitting base 1 is kept flat on template millet cake position, on the fixing hole 2 of base center, with iron nail, screw built-in fitting is fixed on formwork.During disturbing concrete, it is embedded in concrete structure layer, pulls down after formwork, two screw embedded hole positions 3 on base just present.While needing hanging that object is installed, in embedded hole position, 3 screw in little self-tapping screw, the object that suspended erection weight is lighter; Pack expansion bolt into, suspended weight.
Most preferred embodiment
As Fig. 2, screw built-in fitting, comprise built-in fitting base 1, and upper semisection aperture, one of base center is greater than the pentagonal prism shape embedded hole 3 in lower semisection aperture and two circular spaghetti fixing holes 2 that base is equally spaced, fixed hole position 2 has rib 4 to be connected with 3 of embedded hole positions.
At building body floor concrete formwork, complete, while not carrying out casting and compacting of concrete, with reference to construction drawing, on expectation use screw point position, carry out pre-buried.Screw built-in fitting base 1 is kept flat on template millet cake position, on base, on two fixed hole positions 2, with iron nail, screw built-in fitting is fixed on formwork.During disturbing concrete, it is embedded in concrete structure layer, pulls down after formwork, left the screw embedded hole position 3 of base center.While needing hanging that object is installed, in embedded hole position, screw in a little bigger self-tapping screw suspended heavier object is installed.
It is same as the prior art that the utility model is not stated part.
