The utility model patent with the publication number of CN205804616U discloses an embedded part for fixing I-steel in building construction, which comprises a falling plate, a screw rod and a PVC pipe, wherein the falling plate is installed and fixed on a floor slab template during construction, the two screw rods are welded on the corresponding falling plates, the PVC pipe is sleeved on the screw rod, and the PVC pipe is not adhered to concrete, so that the connecting piece of the falling plate and the screw rod is detachable after the construction is finished, and the aim of recycling is fulfilled. However, when the PVC pipe is sleeved, the PVC pipe is also required to be fixed by an iron wire and the upper part of the PVC pipe is plugged by an adhesive tape, so that the concrete is prevented from entering the PVC pipe to contact the pipe to pollute the screw, the consumption of materials is increased, and the construction cost is increased.
Disclosure of Invention
In view of the above, the utility model aims to provide a reusable overhanging I-steel embedded part, so as to solve the problems of complicated construction steps, reduced construction efficiency and increased construction cost caused by using a U-shaped embedded part protective sleeve or a PVC pipe to connect an embedded screw.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: reusable I-steel built-in fitting encorbelments includes:
the embedded part body comprises a base arranged on the template and a screw fixedly connected to the base, and the upper part of the screw is provided with threads;
the rubber protection sleeve comprises a base protection sleeve and a screw protection sleeve, and the base protection sleeve and the screw protection sleeve are integrally formed; the base protection sleeve is matched with the base, a hole for the embedded part body to pass through is formed in the bottom surface of the base protection sleeve, and pressing edges which are attached to the base and the ground are arranged on two sides of the hole; the screw protection sleeve is matched with the screw, and the length of the screw protection sleeve is longer than the length of the screw embedded in the concrete floor slab.
Further, the cross section of the base is rectangular.
Further, the hole at the bottom of the base protective sleeve is rectangular, the size of the rectangle is smaller than the cross section size of the base, and four sides of the hole are connected through circular arcs.
Further, two fixing holes for the iron nails to pass through are formed in the base and the base protective sleeve, and projections of the fixing holes are located in the holes.
Further, the screw is welded on the base.
The beneficial effects of the technical scheme are as follows:
before construction, the embedded part body passes through the hole formed in the bottom of the rubber protective sleeve, and as the size of the hole formed in the bottom of the embedded part protective sleeve is slightly smaller than the section of the base, and the four sides of the hole are connected by the circular arc, the base protective sleeve is easy to wrap the edge of the base, so that the embedded part protective sleeve is fixed on the embedded part body, and after the embedded part is placed, the protective sleeve and the screw rod are not required to be fixed respectively, so that the construction steps are simplified, and the construction efficiency is improved. The base and the base protective sleeve are provided with the fixing holes for the iron nails to pass through, the embedded part body sleeved with the embedded part rubber protective sleeve can be fixed on the template through the iron nails, and the problem that the embedded part is reworked due to displacement of the embedded part caused by external force in the concrete pouring and solidification process is prevented.
Because screw rod protective sheath and base protective sheath are integrated into one piece, the length of screw rod protective sheath is greater than the length of screw rod embedding in concrete floor, the hole that the base protective sheath was seted up makes the bottom surface of base protective sheath form the blank holder that laminates mutually with ground and base, need not to operate in addition before pouring concrete just can ensure that the built-in fitting body does not receive the pollution of concrete, easy operation has improved the efficiency of construction greatly, and need not additionally to use other materials, has saved construction cost.
After construction, because rubber material and concrete do not bond, strike the screw rod with the rubber hammer when dismantling and can take off the built-in fitting completely to make the built-in fitting used repeatedly, practice thrift construction cost. In addition, when in use, the embedded parts are arranged on two sides of the I-shaped steel beam in pairs, and the placement position of the base can be adjusted according to the widths of the wing plates of different I-shaped steel beams, so that the distance between the screw rods is controlled, and the reusable range of the embedded parts is enlarged.
