Detailed Description
For the purpose of facilitating understanding, the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1 and 2, taking an upper steel bar 1 and a lower steel bar 7 to be connected as an example, the upper steel bar 1 and the lower steel bar 7 are exposed steel bars of a PC component to be connected, and the steel bar connecting assembly comprises an upper connecting plate 2, a lower connecting plate 8 and two groove-shaped connecting pieces 9, wherein as shown in fig. 4, a threaded hole 23 in threaded connection with the upper steel bar 1 is formed in the middle of the upper connecting plate 2, and bolt holes 22 are formed in two ends of the upper connecting plate 2; as shown in fig. 6, the middle of the lower connecting plate 8 is provided with a through hole 81 for the lower steel bar 7 to pass through, and two ends of the lower connecting plate 8 are provided with bolt holes 82; as shown in fig. 7, the groove-shaped connecting member 9 is C-shaped, and bolt holes 91 are formed in flanges at both ends of the groove-shaped connecting member 9. In addition, the reinforcing bar connecting assembly further comprises a nut 5, and a bolt 4 and a nut 3 which are matched with each other.
The method of using the rebar junction assembly is as follows: firstly, the upper connecting plate 2 is installed on the upper reinforcing steel bar 1, the lower connecting plate 8 is installed on the lower reinforcing steel bar 7, the external thread (see fig. 3) of the upper reinforcing steel bar 1 is connected with the threaded hole 23 of the upper connecting plate 2, the external thread (see fig. 5) of the lower reinforcing steel bar 7 is connected with the nut 5, and the two nuts 5 clamp and fix the lower connecting plate 8 (in order to improve stability, a backing ring 6 can be arranged between the lower connecting plate 8 and the nut 5). After the upper connecting plate 2 and the lower connecting plate 8 are installed, the upper connecting plate 2 and the lower connecting plate 8 are approximately parallel to each other, then the groove-shaped connecting pieces 9 are buckled at the two ends of the upper connecting plate 2 and the lower connecting plate 8, when the groove-shaped connecting pieces 9 are installed, the distance between the upper connecting plate 2 and the lower connecting plate 8 can be finely adjusted by adjusting the positions of the nuts 5, and two flanges of the groove-shaped connecting pieces 9 can be respectively buckled on the upper connecting plate 2 and the lower connecting plate 8. After the groove-shaped connecting piece 9 is fastened, a bolt hole 91 at the upper end of the groove-shaped connecting piece 9 is aligned to a bolt hole 22 of the upper connecting plate 2, a bolt hole 91 at the lower end of the groove-shaped connecting piece 9 is aligned to a bolt hole 82 of the lower connecting plate 8, finally, two bolts 4 sequentially penetrate through the bolt holes 22 and the bolt holes 91 and are screwed with nuts 3 to fix the upper connecting plate 2 with the groove-shaped connecting piece 9, the other two bolts 4 sequentially penetrate through the bolt holes 82 and the bolt holes 91 and are screwed with nuts 3 to fix the lower connecting plate 8 with the groove-shaped connecting piece 9, and therefore.
As shown in fig. 1 and 2, in order to make the screw hole 23 of the upper connecting plate 2 have a long length, a convex ring portion 21 may be provided at a middle portion of the upper connecting plate 2, and the screw hole 23 extends to an inner wall of the convex ring portion 21. In a specific practical application, the protruding ring part 21 may be a structure integrally formed with the connecting plate 2, or may be a part welded to the connecting plate 2.
It can be seen from the above-mentioned method of use that the distance between the upper connecting plate 2 and the lower connecting plate 8 can be finely adjusted by adjusting the position of the nut 5, so as to ensure that the groove-shaped connecting member 9 can be smoothly fastened, which is to say, the position of the lower connecting plate 8 is adjusted, it is easy to understand that the connection between the upper connecting plate 2 and the upper steel bar 1 can be changed into the connection between the lower connecting plate 8 and the lower steel bar 7, so that the positions of the upper connecting plate 2 and the lower connecting plate 8 can be adjusted, that is, at least one of the two connecting plates needs to have a through hole in the middle for the exposed steel bar of the PC member to pass through.
If only one of the two connecting plates is provided with a through hole in the middle like the lower connecting plate 8, the other connecting plate can be connected with the steel bar in other ways such as welding and the like besides being connected with the steel bar thread like the upper connecting plate 2, as long as the connecting plate can be fixed on the exposed steel bar of the PC component, and the connecting plates without adjusting the positions are usually pre-installed on the PC component production line in consideration of the field situation of construction, for example, when the upper steel bar 1 is still on the PC component production line, the upper connecting plate 2 is connected with the upper steel bar 1, and when the construction site is reached, other parts left by the steel bar connecting assembly are connected.
After the two PC components are hoisted in place at the construction site, if there is a large coaxiality deviation between the upper steel bar 1 and the lower steel bar 7, the bolt holes 91 of the groove-type connecting member 9 are difficult to align with the bolt holes on the connecting plate, which may affect the normal installation of the bolts 4, and for this reason, the bolt holes 91 may be designed as long holes to ensure that the bolts 4 can smoothly pass through the bolt holes on the connecting plate and the bolt holes 91 on the groove-type connecting member 9 in sequence.
In a specific practical application, the distance between the flanges at the two ends of the groove-shaped connecting member 9 may be 10cm to 30cm, for example 20cm, and the distance between the two bolt holes 22 and the distance between the two bolt holes 82 may be 3cm to 10cm, for example 5cm or 8 cm.
Based on the reinforcing steel bar connecting component provided by the invention, the invention also provides a method for building by utilizing the PC component, which comprises the following steps:
and S1, after the two PC components to be connected are hoisted in place in a construction site, the two connecting plates are respectively installed on the exposed steel bars of the two PC components, so that the exposed steel bars are fixedly connected with the middle parts of the connecting plates.
Taking fig. 1 and 2 as an example, the purpose of step S1 is to fixedly connect the upper connecting plate 2 with the upper reinforcement bar 1, and the lower connecting plate 8 with the lower reinforcement bar 7.
S2, buckling the two groove-shaped connecting pieces 9 to two ends of the connecting plate respectively, wherein the groove-shaped connecting pieces 9 and the connecting plate are enclosed into a square shape, and bolt holes 91 at two ends of each groove-shaped connecting piece 9 are aligned to bolt holes of the two connecting plates respectively.
Taking fig. 1 and 2 as an example, the purpose of step S2 is to make the groove-shaped connecting members 9 snap onto the upper connecting plate 2 and the lower connecting plate 8 so that the upper connecting plate 2, the lower connecting plate 8 and the two groove-shaped connecting members 9 enclose a square shape, the bolt holes 91 at the upper ends of the groove-shaped connecting members 9 are aligned with the bolt holes 22 of the upper connecting plate 2, and the bolt holes 91 at the lower ends of the groove-shaped connecting members 9 are aligned with the bolt holes 82 of the lower connecting plate 8, ready for the installation of the bolts 4.
And S3, sequentially penetrating the bolt 4 through the bolt hole of the connecting plate and the bolt hole 91 of the groove-shaped connecting piece 9, and then screwing and fixing the nut 3 and the bolt 4.
Taking fig. 1 and 2 as an example, the step S3 is to fix the upper connecting plate 2 to the channel-shaped connecting member 9 and the lower connecting plate 8 to the channel-shaped connecting member 9, thereby completing the connection of the upper reinforcement 1 to the lower reinforcement 7.
In practical applications, if one of the two tie plates is not provided with a through hole in the middle as the lower tie plate 8, then this tie plate can be used in the PC component production line in advance, so that the aforementioned step S1 only operates the other tie plate, and as shown in fig. 1 and 2, in the PC component production line, the PC component where the upper reinforcement bar 1 is located uses the upper tie plate 2, i.e., the upper tie plate 2 is pre-installed before the PC component is transported to the construction site, so that the step S1 only installs the lower tie plate 8 on the lower reinforcement bar 7, and specifically, the lower tie plate 8 is clamped and fixed on the lower reinforcement bar 7 by the two nuts 5 at the construction site.
When the PC member is used for construction, the region where the exposed steel bars are located is poured after the step S3 to form the pouring connecting strip, as can be seen from fig. 2, the steel bar connecting assembly provided by the present invention can improve the space utilization rate in the pouring connecting strip, and improve the overall strength of the pouring connecting strip.
It should be noted that the present invention is described above with respect to the reinforcing bars 1 and the lower reinforcing bars 7 by way of example, but the use of the reinforcing bar connecting assembly is not limited by the form of the positions of the reinforcing bars, and for example, the reinforcing bar connecting assembly of the present invention can be used with two reinforcing bars to be connected arranged side by side.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
