Abstract
The utility model relates to an embedded bolt anchoring device for fixing cantilever I-shaped steel in building construction and aims at solving the problem that embedded bolts of a cantilever I-shaped steel anchoring device cannot be detached and recycled. The device comprises a pressing plate, connecting bolts, a base, casings and a positioning cover plate, through holes are formed in the base, grooves are arranged below the through holes, the casings are installed on the base, the length of the casing corresponds to the thickness of a floor slab, through holes are formed in the positioning cover plate, and the positioning cover plate is sheathed on the casings to form a connecting structure that the base and the positioning cover plate isare positioned through the casings and is are locked by the connecting bolts and nuts. The device aims at overcoming the defects in the prior art and the embedded bolt anchoring device provided by the utility model has the advantages that the structure is simple, the device is convenient to disassemble and assemble and the device can be repetitively used. The embedded bolt anchoring device is applicable to the installation and the fixation of the cantilever I-shaped steel in the building construction field.
Description
Technical field
The utility model relates to the realm of building construction, relates in particular to a kind of device with pre-embedded bolt cantilever mounted i iron.
Background technology
The i-steel component of encorbelmenting is widely used in the support of encorbelment construction and the overhanging type discharging platform of external scaffolding in building operations.At present, traditional i iron anchoring process has three kinds: 1, on floor, pre-buried door shape round steel and bottom, door limit, to horizontal both sides extension, form non-dismountable structure, are fixed on floor.2, on floor, pre-buried U-shaped screw rod and U-shaped base are placed in concrete and form non-dismountable structure, are fixed on floor.3, on floor, pre-buried U-shaped screw rod and U-shaped base are placed in the bottom (bottom layer of the reinforcing steel bottom) of concrete thickness, and both sides screw rod adopts plastic bushing parcel, encapsulation process, forms the demountable structure of U-shaped screw rod, is fixed on floor.Above-mentioned three kinds of methods, the pre-buried door of first two shape round steel and U-shaped screw rod are non-dismountable, consume material, although rear a kind of detachable, make, installation requirement is high, during dismounting, bottom concrete need to be pounded remove and repair perfect, increase construction cost.And the installation of the i iron anchoring piece of encorbelmenting, dismounting be if reach fixing reliable, that easy installation and removal and component are made is simple, cost is low, can reuse, and has applicable and promotional value.
Utility model content
The utility model has overcome shortcoming of the prior art, provides that a kind of making is simple, easy accessibility, the pre-embedded bolt anchor device that can reuse.
The technical scheme that the utility model is realized the employing of utility model object is: the pre-embedded bolt anchor device that is used for fixing cantilever i iron in a kind of building operations, comprise pressing plate, threaded fixed bar, described threaded fixed bar is connecting bolt, this device also comprises base, sleeve pipe, positioning cover plate, on base, be provided with through hole, through hole is arranged with groove, sleeve pipe is arranged on base, the length of sleeve pipe is corresponding with the thickness of floor, on positioning cover plate, be provided with through hole, positioning cover plate is sleeved on sleeve pipe, form base, sleeve pipe, the syndeton of positioning cover plate, pass through pressing plate, the nut i iron of encorbelmenting is fixed on floor.
Base, sleeve pipe, positioning cover plate can be injection molded into integral structure, and base groove is rectangular recess, and connecting bolt is lag screw, and perimeter profile can be made taper according to removing direction.
The beneficial effects of the utility model are: this device is made simple, easy accessibility, can reuse.
Below in conjunction with accompanying drawing and the specific embodiment, the utility model will be further described.
Accompanying drawing explanation
fig. 1 is assembling front view;
Fig. 2 is the top view of base 1;
Fig. 3 is the upward view of positioning cover plate 3.
In figure, base 1, sleeve pipe 2, positioning cover plate 3, connecting bolt 4, nut 5, pressing plate 6, square washer 7.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model will be further described.
The pre-embedded bolt anchor device of cantilever mounted i iron as shown in Figure 1, this device comprises pressing plate, connecting bolt, also comprise base, sleeve pipe, positioning cover plate, be provided with through hole on base, through hole is arranged with groove, sleeve pipe is arranged on base, the length of sleeve pipe is corresponding with the thickness of floor, is provided with through hole on positioning cover plate, and positioning cover plate is sleeved on sleeve pipe, form the syndeton of base, sleeve pipe, positioning cover plate, by pressing plate, the nut i iron of encorbelmenting, be fixed on floor.
For reducing assembling link, its base, sleeve pipe, positioning cover plate can be injection molded into integral structure, and base groove is rectangular recess, and connecting bolt is lag screw, and perimeter profile is made taper according to removing direction, is convenient to remove.
The technology of carrying out before construction is prepared, and each part is got all the ready.Thereby the position that base is made in the installation site of determining i iron according to construction requirement in template.Base, sleeve pipe, positioning cover plate, connecting bolt, square washer are assembled, with steel nail, be fixed in template.Check and correction installation site, accurate after, take off positioning cover plate concreting, intensity reaches after installation requirement, anchoring i iron, completes installation work.After engineering finishes, unload lower nut, pressing plate, withdrawal connecting bolt, square washer, i iron, recycling is to next engineering.
