Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and specifically relates to a reinforcing steel bar binding limiting tool. Background Art

[0002] In traditional reinforcing steel bar binding, the pre-cut stirrups are first bound and fixed with the main bars at four corners, then the positions of other main bars are further determined, and finally all the reinforcing steel bars are bound. However, limited by the size of the stirrups, deviations often exist in the spacing, margin and other parameters of the main bars. For the production of common components, the position deviation of reinforcing steel bars has little impact as long as normal installation can be realized in the later stage. But for components with high requirements on reinforcing steel bar spacing used in scientific research tests and the like, if the existing binding process is still adopted, it is very likely that the requirements cannot be met, and continuous adjustments are required subsequently, which wastes labor and time. With the release of the new prefabricated building evaluation standard in Zhejiang Province, formed reinforcing steel bar binding will also be gradually applied in the near future. If the existing reinforcing steel bar binding method is used for processing formed reinforcing steel bars later, when the reinforcing steel bars are transported to the construction site for installation and it is found that the deviation is too large to be installed and secondary adjustment is required, not only the advantages of this method cannot be reflected, but also it will be a strong resistance to the implementation of specifications.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-3 As shown, a rebar tying limiting tool includes two identical limiting frames 6, as well as a template 7 and a base plate assembly 1 set on the limiting frames 6.

[0019] Template 7 is a detachable wooden template, and its size is adapted to the cross-sectional size of the steel reinforcement component to be tied. Considering that the steel reinforcement needs to be suspended at a certain distance, the bottom of template 7 is raised. The template 7 has steel reinforcement positioning holes 4 according to the position of the main reinforcement 13 to be tied. The diameter of the holes is slightly larger than the diameter of the main reinforcement 13 to be tied, so as to ensure that the main reinforcement 13 can pass through and cannot move significantly.

[0020] The limiting frame 6 is used to clamp and fix the template 7. It includes two sets of "U"-shaped limiting frames. The outer contour size of the limiting frame 6 is the same as that of the template 7. Bolt holes 8 are set on each side of the limiting frame 6 at a certain interval. A connecting steel plate 9 is provided on the outer side of the limiting frame 6. After the first bolt 10 passes through the connecting steel plate 9 and the bolt hole 8 in sequence, the entire device is connected and fixed by the nut 5 at the corresponding position on the inner side of the limiting frame 6.

[0021] A base plate assembly 1 is fixedly installed at the bottom of the limiting frame 6. The base plate assembly 1 consists of an upper whole plate 101 and a number of lower segmented plates 102. The whole plate 101 is fixed to the limiting frame 6 by a second bolt 11 passing through the bolt hole 8. The segmented plates 102 are at least two independent plates and are evenly distributed along the length of the whole plate 101 to prevent unevenness at the bottom due to the presence of nuts 5 in some parts of the whole plate 101, which would prevent stable placement. To ensure stability, a support plate 3 is provided in the middle of the limiting frame 6. The support plate 3 is close to the outer side of the template 7. Similarly, a retaining strip 12 is provided inside the limiting frame 6. The upper and lower ends of the support plate 3 are fixed to the retaining strip by a third bolt 2. The third bolt 2 passes through the retaining strip bolt hole 1201 and is connected and fixed to the retaining strip nut 1202 at the corresponding position on the retaining strip.

[0022] like Figure 4 As shown, during use, the device is placed at both ends of the main reinforcement bar 13 to be tied. After inserting the stirrups 14 into the main reinforcement bar 13, both ends of the main reinforcement bar 13 are then inserted into the reinforcement positioning holes 4 on the formwork 7. After the device is stably fixed, the spacing of the main reinforcement bar 13 will not change. At this time, the stirrups 14 can be tied. After the tying is completed, the limiting devices at both ends are removed, and the reinforcement cage is tied. If the diameter and spacing of the main reinforcement bar 13 to be tied change, only the formwork 7 and the reinforcement position need to be replaced. It is applicable to reinforcement bars with the same cross-sectional size.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
