Description

Rust prevention device for construction engineering reserved steel bars

Technical Field

The utility model belongs to the technical field of building engineering, especially, relate to an antirust device of building engineering reserved steel bar.

Background

When the building engineering is under construction, because the bending resistance of concrete is poor, consequently often need to match the use each other with the reinforcing bar for floor or post not only have the intensity of concrete, have the toughness of reinforcing bar simultaneously, and the building just can be more firm like this.

Because the cement in the concrete needs water for hydration, the water used for cement hydration in the concrete can be dried through for years or even for ten years after the concrete reaches a surface dry state, so that the steel bars positioned in the concrete are always in a humid environment, the surfaces of the steel bars are easy to rust, the tensile strength and the breaking strength of the rusted steel bars are greatly reduced, and brittle fracture is easy to generate.

SUMMERY OF THE UTILITY MODEL

The problem to prior art exists, the utility model provides an antirust device of constructional engineering reservation reinforcing bar, last PVC pipe box through setting up can cup joint the reinforcing bar through the connecting hole with PVC pipe box down, thereby better wrap up the reinforcing bar, then will go up PVC pipe box and connect with PVC pipe box down through first mounting disc and second mounting disc, then will go up PVC pipe box and fix PVC pipe box down through the threaded rod, make to connect more convenience, then can be better polish and dry the reinforcing bar through the layer of polishing and the dry layer that sets up, thereby better place the reinforcing bar and take place to rust.

The utility model discloses a realize like this, including last PVC pipe box and lower PVC pipe box, go up the first mounting disc of lower extreme fixedly connected with of PVC pipe box, the upper end fixedly connected with second mounting disc of PVC pipe box down, open the upper end of first mounting disc and run through and be equipped with the screw hole, the thread groove has been seted up to the upper end of second mounting disc, threaded connection has the threaded rod in the screw hole, the inboard of going up PVC pipe box and lower PVC pipe box runs through and has seted up the connecting hole, the reinforcing bar has been cup jointed in the connecting hole.

As the utility model discloses it is preferred, the inboard of connecting hole is provided with the layer of polishing, one side on the layer of polishing is provided with dry layer.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses a last PVC pipe box that sets up can cup joint the reinforcing bar through the connecting hole with lower PVC pipe box to better wrap up the reinforcing bar, then will go up PVC pipe box and connect PVC pipe box down through first mounting disc and second mounting disc, then will go up PVC pipe box and fix PVC pipe box down through the threaded rod, make to connect convenience more, then can be better polish and dry the reinforcing bar through the layer of polishing and the dry layer that sets up, thereby better placing the reinforcing bar and taking place to rust.

2. The utility model discloses a layer and the dry layer of polishing that sets up through the inboard setting at the connecting hole layer of polishing, then one side of the layer of polishing set up that dry layer can be better will through the reinforcing bar can polish through the layer of polishing when the atress takes place to deform to prevent to rust, through the dry in the assurance PVC pipe box that the dry layer that sets up can be fine moreover, reduced rusty emergence.

Drawings

Fig. 1 is a schematic structural diagram provided in an embodiment of the present invention;

fig. 2 is an enlarged view of a portion a in fig. 1 according to an embodiment of the present invention.

In the figure: 1. coating a PVC pipe sleeve; 2. a PVC pipe sleeve is arranged; 3. connecting holes; 4. a first mounting plate; 5. a threaded hole; 6. a thread groove; 7. a threaded rod; 8. drying the layer; 9. polishing the layer; 10. reinforcing steel bars; 11. a second mounting plate.

Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.

The structure of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to fig. 2, the embodiment of the utility model provides a pair of rust-proof device of reinforcing bar is reserved to building engineering, including last PVC pipe box 1 and PVC pipe box 2 down, go up the first mounting disc 4 of lower extreme fixedly connected with of PVC pipe box 1, the upper end fixedly connected with second mounting disc 11 of PVC pipe box 2 down, open the upper end of first mounting disc 4 and run through and be equipped with screw hole 5, thread groove 6 has been seted up to the upper end of second mounting disc 11, threaded connection has threaded rod 7 in the screw hole 5, go up PVC pipe box 1 and run through with the inboard of PVC pipe box 2 down and seted up connecting hole 3, the reinforcing bar 10 has been cup jointed in connecting hole 3.

Referring to fig. 1, a polishing layer 9 is provided at an inner side of the connection hole 3, and a drying layer 8 is provided at one side of the polishing layer 9.

Adopt above-mentioned scheme: through the layer 9 and the dry layer 8 of polishing that set up, through the inboard at connecting hole 3 set up the layer 9 of polishing, then one side of the layer 9 of polishing set up that dry layer 8 can be better will through reinforcing bar 10 when the atress takes place to deform can polish through layer 9 of polishing, thereby prevent to rust, through the dry layer 8 drying in the assurance PVC pipe box that sets up can be fine moreover, reduced rusty emergence.

The utility model discloses a theory of operation:

when using, at first cup joint reinforcing bar 10 through last PVC pipe box 1 and connecting hole 3 in the PVC pipe box 2 down, thereby wrap up reinforcing bar 10, then will go up PVC pipe box 1 and fix PVC pipe box 2 down through first mounting disc 4 and second mounting disc 11, thereby fix reinforcing bar 10, then bury reinforcing bar 10, make through the dry layer 8 that sets up keep dry throughout in the PVC pipe box, thereby rusty phenomenon has been prevented to appear reinforcing bar 10, then can polish at the in-process that reinforcing bar 10 takes place deformation through the polishing layer 9 that sets up, thereby the place of embroidering now is polished, better improvement the intensity of reinforcing bar.

In summary, the following steps: this rust-proof device of steel bar is reserved to building engineering, last PVC pipe box 1 through the setting, lower PVC pipe box 2, connecting hole 3, first mounting disc 4, screw hole 5, thread groove 6, threaded rod 7, dry layer 8, the layer 9 of polishing, the cooperation of reinforcing bar 10 and second mounting disc 11 is used, the cement hydration of having solved because in the concrete needs water, its inside water that is used for cement hydration probably will do thoroughly several years even ten years after the concrete reaches the surface dry state, consequently its reinforcing bar that is located concrete inside is in a moist environment always, the reinforcing bar surface rusts just so easily very much, its tensile rupture strength of reinforcing bar after rustting all can greatly reduced, very easily produce brittle fracture's problem.
