Detailed Description
The present invention will be further described with reference to the following examples, which are intended to illustrate only some, but not all, of the embodiments of the present invention. Based on the embodiments in the present invention, other embodiments used by those skilled in the art without creative efforts all belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; furthermore, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, as they may be fixedly connected, detachably connected, or integrally connected, for example; may be a mechanical connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
With reference to the attached drawing 1, the conventional stirrup common structure for buildings comprises a connecting steel bar 1, a plurality of supporting legs 2 are connected to the lower end of the connecting steel bar 1, each supporting leg 2 comprises two supporting legs 21, the two supporting legs 21 are respectively inclined and connected below the connecting steel bar 1, in the specific manufacturing process, the two supporting legs 21 are generally bent to form the supporting legs 2, and then the supporting legs are directly welded below the connecting steel bar 1. In the use process of the stirrup with the structure, as constructors need to walk on top layer steel bars, the problem that the support legs 2 of the stirrup are easy to deform and collapse is solved. That is to say, two landing legs 21 of supporting leg 2 incline each other and are the connection of "eight" style of calligraphy in the below of connecting reinforcement 1, and the supporting leg very easily takes place to warp and collapses, leads to the stirrup to lose the effect of support.
With reference to fig. 1, the stirrup described in the present application refers to a stirrup capable of simultaneously supporting a plurality of transverse reinforcements (or a plurality of longitudinal reinforcements) arranged side by side in top reinforcements during building construction. That is to say that the stirrup of this application teaching is the structure of the structural muscle that can support the top layer reinforcing bar of floor in the building construction process. Wherein, many horizontal reinforcing bars that set up side by side and many vertical reinforcing bars that set up side by side are the structural muscle of top layer reinforcing bar.
Meanwhile, the existing stirrup only plays a role in supporting the top layer steel bars of the floor slab in the using process, and is not mutually connected with the bottom layer steel bars and the top layer steel bars of the floor slab, so that the stirrup is easy to slide and deflect, and the top layer steel bars are not supported. In addition, the existing stirrup only plays a supporting role, does not have other auxiliary functions, and has a single function.
The thickness of the floor slab is generally between 80 and 120mm, the thickness of the protective layer of the bottom layer steel bars (formed by bundling the transverse steel bars and the longitudinal steel bars) and the top layer steel bars (formed by bundling the transverse steel bars and the longitudinal steel bars) of the floor slab is generally about 15mm, namely, the distance between the lower end surface of the structural bars (the transverse steel bars and the longitudinal steel bars) of the bottom layer steel bars and the lower bottom surface of the floor slab is generally about 15mm, and the distance between the upper end surface of the structural bars of the top layer steel bars and the upper surface of the floor slab is generally about 15 mm. Thus, the overall height of the stirrup is generally between 60 and 90 mm. Referring to fig. 1, the height of two legs 21 of the support leg 2 in the prior art is the height of the stirrup minus the outer diameter of the connecting bar 1 (the diameter of the connecting bar is typically 3.5-4.2 mm). Therefore, the overall height of the two legs 21 is high, and the two legs 21 are distributed in an "eight" shape, so that the legs 21 are easily deformed and collapsed.
Based on the above problems, the present application provides a stirrup for being placed between top and bottom reinforcing bars of a floor slab, including a first connecting reinforcing bar 11, a second connecting reinforcing bar 12 and a plurality of connecting rods, where the first connecting reinforcing bar 11 and the second connecting reinforcing bar 12 are parallel to each other; the first connecting steel bar 11, the second connecting steel bar 12 and the connecting rod are connected together to form a columnar stirrup; the first connecting steel bar 11 is used for contacting with a structural bar of a top steel bar of the floor slab, or the first connecting steel bar 11 is used as a part of the structural bar of the top steel bar of the floor slab; the second connecting reinforcement 12 is used for contacting with the structural reinforcement of the bottom reinforcement of the floor slab, or the second connecting reinforcement 12 is used as a part of the structural reinforcement of the bottom reinforcement of the floor slab.

Wherein the thickness of the concrete protective layer is understood and appreciated by those skilled in the art and will not be described in detail herein.
And the stirrup of this application is directly placed between the top layer reinforcing bar and the bottom reinforcing bar of floor, consequently, after the concrete placement of floor is accomplished, whole stirrup all wraps up in the concrete, the stirrup also can not with the template contact when pouring the floor, the exposed and corrosion problem of stirrup appears after having avoided the form removal, make the floor bottom surface no longer carry out the seam repair because of the stirrup simultaneously, improve the shaping quality of floor. Among the prior art, the stirrup is all directly placed on die block (bottom template) when pouring the floor, demolishs the back when die block (bottom template), because the bottom of stirrup flushes with the bottom surface of floor to make stirrup bottom expose and take place the problem of corrosion easily, follow-up still need sew up.
