Description

Reinforcement splicer set and protective cover thereof

This creation is about a steel splicer group and its protective cover, especially a steel splicer group and its protective cover used in the field of steel splicing.

At present, the reinforcing bars are continuously extended. A reinforcing bar is usually used as a connecting member between the reinforcing bars, wherein one end of the reinforcing bar is fixed to a reinforcing bar end, and then the fixing hole in the reinforcing bar is provided. The end of the other reinforcing bar is fixed therein. In the process of constructing the steel bar, in order to avoid the fixing hole of the steel bar splicer not being fixed to the steel bar, the foreign object enters the fixing hole of the steel bar splicer to block, and affects the subsequent work of fixing the steel bar to the steel splicer. Most of the workers will cover the end of the reinforcing bar before the reinforcing bar is fixed to the end of the reinforcing bar before the reinforcing bar is fixed.

However, due to the use of the reinforcing bar splicer, after the reinforcing bar is fixed to the end of the reinforcing bar, it must be welded and fixed, so the plastic protective cover cannot be pre-covered with the end of the steel splicer, otherwise it will It is melted by the high temperature of the steel bar splicer welding work. However, after the steel bar splicer is constructed on the reinforced concrete foundation, the operator often arranges the plastic protective cover to the splicer end of the steel bar due to the dense arrangement of the steel bars or the deep position. The difficulty of the department. Furthermore, the plastic protective cover is constructed by arranging the outer side of one end of the reinforcing bar splicer In the construction work, the plastic protective cover is easily detached by external force.

The main purpose of this creation is to provide a steel splicer set and its protective cover. It is intended to solve the problem that the existing plastic protective cover cannot be pre-covered at the end of the reinforcing splicer, and it is difficult to cover the plastic protective cover after the steel is constructed. Problems with the rebar adapter.

In order to achieve the above objective, the rebar combination of the present invention comprises: a steel rebar splicer having a fixing hole, the fixing hole being a port at one end of the rebar splicer; and a metal material The protective cover is detachably assembled in a fixing hole at one end of the reinforcing bar splicer, and the protective cover includes a receiving portion having a recessed portion, and one end of the peripheral wall of the inserting portion forms a closed end having an end wall, The recessed portion is an open end at the other end of the peripheral wall, and the insertion portion radially protrudes a ring flange at a periphery of the open end thereof, and the insertion portion of the protective cover can be placed at one end of the fixing hole fixed to the reinforcing bar splicer, and the ring flange is abutted Connect the side end of the reinforcing bar to close the port of the fixing hole.

The rebar retaining cover of the present invention comprises an inserting portion having a recessed portion, and a peripheral end of the peripheral wall of the inserting portion is formed with a closed end having an end wall, the recessed portion being an open end at the other end of the peripheral wall, and the inserting portion A ring flange is radially protruded from a periphery of the open end, and the insertion portion of the protective cover is fixed to one end of the reinforcing bar splicer.

By the front of the reinforcing steel splicer group and the protective cover thereof, the protective cover of the metal material can be pre-installed with one end of the steel splicer, so that the reinforcing splicer is fixed at the high temperature generated by the welding of the end of the steel bar. The protective cover is not damaged, and the protective cover of the metal material can be pre-installed on the reinforcing bar splicer At one end, the construction of the steel bar can be made more simple. Moreover, the protective cover is formed by inserting the port in the reinforcing bar splicer so that the protective cover does not protrude outside the reinforcing bar splicer, so that the protective cover is not easily detached from the reinforcing bar by the external force.

The second purpose of the present invention is to form a plurality of spaced-apart abutting protrusions at the insertion portion of the protective cover to abut the convex portion to abut the fixing hole wall of the reed splicer, adjacent to the convex portion The connecting portion of the gap has a gap with the fixing hole wall of the reinforcing bar splicer, so that the contact portion between the placing portion of the protective cover and the reinforcing bar splicer can be reduced, so that the protective cover is detached from the reinforcing bar splicer from. Furthermore, the peripheral wall of the insertion portion of the protective cover may be a tapered surface structure whose size gradually increases from the end wall toward the opening end, so that the insertion portion of the protective cover can be easily placed in the fixing hole of the reinforcing bar.

The present invention comprises a reinforcing bar adapter set and a protective cover thereof. As shown in FIG. 1, the reinforcing bar adapter set comprises a reinforcing bar adapter 1 and a protective cover 2 as described.

As shown in FIG. 1 , the reinforcing bar splicer 1 is a member made of a steel material, and the reinforcing bar splicer 1 has a fixing hole 10 , and the end of the reinforcing bar 10 is provided with a reinforcing bar fixed therein. The reinforcing bar 1 forms a port 11 at one end of the fixing hole 10, and forms a closed end with the end wall 12 at the other end of the fixing hole 10. Alternatively, as shown in FIG. 6, the reinforcing bar 1 can also be fixed. Ports 11 are formed at both ends of the hole 10. As shown in FIG. 1 and FIG. 5, the hole wall of the fixing hole 10 can be formed with a thread, and the fixing hole 10 is used to provide a threaded end portion of the reinforcing bar to be screwed.
