Description

The present invention relates to a reinforcing bar connecting method used for construction of a foundation plate.

In the construction process, the connection between structures is one of the key factors affecting the overall structural strength.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. Note that the embodiments to be described below are not intended to limit the present invention described in the appended claims. In addition, all of the configurations described below are not necessarily essential requirements of the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the lower layer rebar 100 is crossed with each other with including a plurality of first lower reinforcing bars 110 and a plurality of second lower reinforcing bars 120. The first lower layer reinforcing bars 110 are extended along the first direction a, and are arranged in parallel in the second direction b at equal intervals. The 2nd lower layer reinforcement 120 is extended along the 2nd direction b, and is arranged in parallel at equal intervals in the 1st direction a. After bundling the lower layer reinforcing bars 100, the mat 130 is put on the installation surface according to demand and is protected by lifting. An upper layer reinforcing bar 200 is installed above the lower layer reinforcing bar 100. The upper rebar 200 is composed of a plurality of first upper rebars 210 and a plurality of second upper rebars 220 and crosses each other. The first upper-layer reinforcing bars 210 are extended along the first direction a, and are arranged in parallel along the second direction b at equal intervals. The second upper-layer reinforcing bars 220 are extended along the second direction b, and are arranged in parallel along the first direction a at equal intervals. Moreover, the connector 112 which has the protective stopper 114 is installed in the edge part of each 1st lower layer reinforcement 110, and prevents that a foreign material approachs in the construction process.

As shown in FIG. 2, the side plate 300 has an outer surface 302 and an upper surface 304. A plurality of hole portions 306 are formed in the outer side surface 302, and the end portions of the first lower layer reinforcing bars 110 are accommodated in the hole portions 306. A plurality of first concave portions 308 are formed on the other upper surface 304, and the first upper-layer reinforcing bar 210 is straddled over the upper surface 304 and is accommodated in the first concave portion 308. The first upper-layer reinforcing bar 210 straddling the upper surface 304 protrudes outside the end portion of the first lower-layer reinforcing bar 110.

In addition, an auxiliary support structure is optionally installed on the side plate 300. For example, a lateral stop bar 400, a vertical stop bar 600, and an oblique support member 700 are installed, and FIG. 3, FIG. 5 and FIG. Illustrated. The horizontal stop bar 400 is installed between the upper surface 304 and the installation surface and is fixed to the outer surface 302 of the side plate 300. Thereby, the structural strength of the side plate 300 is increased as a whole, and the side plate 300 is prevented from being deformed after grouting (see FIG. 3).

As shown in FIG. 4A, a plurality of second recesses 502 are formed in the lower push bar 500 and correspond to the plurality of first recesses 308 of the side plate 300. Each of the first recess 308 and the second recess 502 surrounds the first upper-layer reinforcing bar 210. The outer shapes of the first concave portion 308 and the second concave portion 502 are semicircular cutouts or the like, and both form a space for accommodating the first upper layer rebar 210 in the radial direction (the first upper and lower rebars 210a in FIG. See one recess and the second recess).

As shown in FIG. 4B, a lower push bar 500 is installed on the upper surface of the side plate 300, thereby sealing the side plate 300 in a space above the first upper layer rebar 210 and further fixing the first upper layer rebar 210. This design prevents leakage from the location of the first upper rebar during grouting. Further, a U-shaped first concave portion 308 is adopted for the side plate 300, the depth of the U-shaped concave portion is substantially equal to the length in the radial direction of the first upper-layer reinforcing bar 210, and the lower push bar 500 has a concave portion. The design is flat without being provided. This saves time for aligning the lower push bar 500 with the side plate 300 when placing the lower push bar 500 (see FIG. 4C).

The lower push bar 500 has a convex edge portion 504 that protrudes from the connecting portion of the lower push bar 500 and the side plate 300 toward the outer surface 302, and the protruding length of the convex edge portion 504 is a lateral stop of the side plate 300. Substantially equal to the depth of the bar 400 (the size protruding from the outer surface), the lower push bar 500 is horizontal to the surface of the lateral stop bar 400 in a direction away from the side plate 300 of the outer surface 302, and the vertical stop bar 600 is fixed to the lower push bar 500 and the lateral stop bar 400 (see FIG. 5). The vertical stop bar 600 and the horizontal stop bar 400 increase the overall structural strength and prevent deformation after grouting. At this time, the lower push bar 500 is horizontal to the outer surface 302 (that is, does not have the convex edge 504), and the vertical stop bar 600 is directly fixed to the side plate 300 and the lower push bar 500.

As shown in FIG. 6, an oblique support member 700 is installed on the outer surface 302. Except for the end surface of the diagonal support member 700 being in contact with the outer surface 302, preferably, the diagonal support member 700 is adjacent to one side of the vertical stop bar 600 to further increase the structural strength of the side plate 300.

Next, as shown in FIG. 7, after concrete is poured into the side plate 300 so as to cover the upper layer rebar 210 and the lower layer rebar, the side plate 300, the lower push bar 500 and other auxiliary support structures are removed, and the partial foundation A plate 810 is completed (see FIG. 8). With this design, not only is the bottom bar and side plate combined with the reinforcing bar, but the combination and removal of both is considerably convenient and construction quality is enhanced.

When the partial foundation plate 810 is completed, the lower layer reinforcing bar 100 and the upper layer reinforcing bar 200 are continuously installed along the first direction a (see FIGS. 9 and 10). The first lower layer reinforcement 110 is connected from the position of the connector 112 to the first lower layer reinforcement 110 of the partial foundation plate 810, and the first upper layer reinforcement 210-2 and the first upper layer reinforcement 210-1 of the partial foundation plate 810. Are connected by a lap joint method. Next, as described above, the erection process of the side plate, the lower push bar, and the support member (for example, a horizontal stop bar, a vertical stop bar) is performed.

As shown in FIG. 11, a partial foundation plate 820 is formed by pouring concrete. The above method is repeated to complete the basic version 800 step by step. The design of the first recess and the hole of the side plate increases the accuracy of rebar alignment and improves the construction efficiency in a stepwise construction process.

As shown in FIG. 12, in step S1010, a lower layer reinforcing bar is installed on the installation surface. The lower layer reinforcing bars are composed of a plurality of first lower layer reinforcing bars and a plurality of second lower layer reinforcing bars and cross each other, and the first lower layer reinforcing bars are arranged in parallel along the second direction at equal intervals. Are arranged at equal intervals along the first direction. In step S1030, the upper layer reinforcing bar is installed above the lower layer reinforcing bar. The upper-layer reinforcing bars are composed of a plurality of first upper-layer reinforcing bars and a plurality of second upper-layer reinforcing bars, intersect with each other, and are arranged in parallel at equal intervals along the second direction and the first direction. In addition, it has a connection apparatus in the edge part of each 1st lower layer reinforcement, Preferably, a connection apparatus is sealed from the opposite side connected to a 1st lower layer reinforcement with a protective stopper. This prevents foreign matter from entering the connector during the construction process and does not affect the connection effect.

In step S1050, a side plate is installed. The side plate has an outer surface and an upper surface connected to the outer surface. A plurality of hole portions are formed on the outer side surface, and a plurality of first concave portions arranged at equal intervals along the second direction are formed on the upper surface. The end of the first lower layer reinforcing bar is housed in the hole, and the first upper layer reinforcing bar is straddled on the upper surface and is housed in the first recess. Further, in the side plate laying step, a plurality of lateral stop bars are arbitrarily installed between the upper surface of the side plate and the installation surface to form an auxiliary support structure. The lateral stop bar is fixed to the outer surface of the side plate. This increases the structural strength of the side plate as a whole and prevents the side plate from being deformed after grouting.

In step S1070, a lower push bar is installed on the upper surface of the side plate. The lower push bar is formed with a plurality of second recesses and corresponds to the plurality of first recesses of the side plate. Both the first recess and the second recess surround the first upper-layer reinforcing bar. In the lower push bar installation step, a plurality of vertical stop bars are optionally installed on the side plate and the lower push bar. The vertical stop bar is connected to the lower push bar and the side plate to form a side plate support member, and the diagonal support member is installed on the outer surface. The oblique support member is preferably adjacent to one side of the vertical stop bar to further enhance the structural strength of the side plate. In step S1090, concrete is poured so as to cover the upper layer reinforcing bar and the lower layer reinforcing bar to form a partial foundation plate. The partial foundation plates are continuously completed along the connection direction (for example, the first direction), and the partial foundation plates are connected to complete the construction of the foundation plate. The design of the first concave portion and the hole portion of the side plate increases the accuracy of rebar alignment and improves the construction efficiency.
