Abstract
Description
Technical Field
[0001] This utility model relates to the field of PC wall panel production technology, and more specifically, to a quick positioning clamp for installing steel bars in PC wall panels. Background Technology
[0002] PC components refer to concrete products manufactured in factories using standardized and mechanized methods. They are widely used in construction, transportation, water conservancy, and other fields. PC components are prefabricated in factories and then assembled on-site, offering advantages such as energy saving, environmental protection, and cost reduction. However, in the current production of PC components, it is necessary to reinforce the steel bars to increase the strength of the components. In the existing steel bar placement, the position of the steel bars is mostly fixed manually and arbitrarily, which makes it difficult to maximize the force that the steel bars can withstand, thus affecting the overall strength of the components. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a quick positioning clamp for installing steel bars in PC wall panels, which has the advantage of controlling the position of the steel bars and maximizing the load-bearing capacity of the components.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick positioning clamp for installing rebar in PC wall panels, comprising a base, a sliding groove inside the base, a slider slidably connected inside the sliding groove, a positioning hole inside the slider, a vertical rebar inserted into the positioning hole, an installation groove and a scale on the top of the base, a connecting plate fixedly installed on the outside of the slider, and a screw hole inside the connecting plate.
[0005] As a preferred embodiment of this utility model, the base has a slot inside, the slot has a block inside, and a vertical plate is fixedly installed behind the block.
[0006] As a preferred embodiment of this utility model, a second sliding groove is provided inside the vertical plate, a second slider is slidably connected inside the second sliding groove, a support plate is fixedly installed in front of the second slider, and a screw is inserted into the rear of the vertical plate, the screw engaging with the second slider.
[0007] As a preferred embodiment of this utility model, a connecting sleeve is sleeved on the outer side of the vertical reinforcing bar, and a limiting rod is fixedly installed on the outer side of the connecting sleeve. There are multiple vertical reinforcing bars, all of which are located above the base, and the limiting rods are respectively located between two of the vertical reinforcing bars.
[0008] As a preferred technical solution of this utility model, there are multiple sliders, all of which are located inside the base and are slidably connected to the slide groove.
[0009] As a preferred embodiment of this utility model, there are two vertical plates, both of which are located behind the base and are parallel to each other. There are multiple sliders and multiple support plates, with the multiple support plates located in front of the two vertical plates respectively.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model features a sliding groove inside the base, a slider slidably connected inside the sliding groove, and a positioning hole inside the slider, into which a vertical reinforcing bar is inserted. When the vertical reinforcing bar needs to be installed, it is first inserted above the slider. The installation is then achieved through the sliding connection between the slider and the sliding groove, causing the vertical reinforcing bar to be moved to a designated position. When installing the next vertical reinforcing bar, its position is moved to a designated location, determined by a ruler, and then fixed, ensuring that the distance between each vertical reinforcing bar is equal. This results in uniform force distribution among the multiple vertical reinforcing bars, maximizing the force distribution.
[0012] 2. This utility model features a groove 2 inside a vertical plate, with a slider 2 slidably connected inside the groove 2. A support plate is fixedly installed in front of the slider 2. When the vertical steel bar is fixed to the designated position, the support plate needs to be fixed by the horizontal steel bar and the horizontal force-bearing area of the component is increased. At this time, the slider 2 is displaced through the sliding connection between the groove 2 and the vertical plate. When it is displaced to the fixed position, the screw engages with the slider 2, fixing the slider 2. Since the support plate and the slider 2 are fixedly connected, the support plate is also fixed. Then, the horizontal steel bar is placed above the support plate and in contact with the vertical steel bar, and then fixed by steel wire, achieving the effect of easy installation and fixing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1 to 5 As shown, this utility model provides a quick positioning clamp for installing rebar in PC wall panels, including a base 1, a sliding groove 2 inside the base 1, a slider 3 slidably connected inside the sliding groove 2, a positioning hole 4 inside the slider 3, a vertical rebar 5 inserted into the positioning hole 4, an installation groove 6 and a scale 9 above the base 1, a connecting plate 7 fixedly installed on the outside of the slider 3, and a screw hole 8 inside the connecting plate 7.
[0021] When it is necessary to install the vertical reinforcing bar 5, first insert the vertical reinforcing bar 5 above the slider 3. Then, the installation is carried out through the sliding connection between the slider 3 and the groove 2, so that the vertical reinforcing bar 5 will be moved to the designated position. When it is necessary to install the next vertical reinforcing bar 5, move the vertical reinforcing bar 5 to the designated position, and fix it after judging by the scale 9, so that the distance between each vertical reinforcing bar 5 is equal, thereby achieving the effect of uniform force distribution among multiple vertical reinforcing bars 5 and maximizing the force distribution.
[0022] The base 1 has a slot 10 inside, and a block 11 is inside the slot 10. A vertical plate 12 is fixedly installed behind the block 11.
[0023] The vertical plate 12 is connected to the slot 10 by the snap-fit action of the snap-fit block 11, so that the vertical plate 12 is fixedly installed behind the base 1 and the vertical plate 12 is kept perpendicular to the base 1.
[0024] The vertical plate 12 has a sliding groove 13 inside, and a slider 14 is slidably connected inside the sliding groove 13. A support plate 15 is fixedly installed in front of the slider 14, and a screw 16 is inserted into the rear of the vertical plate 12. The screw 16 meshes with the slider 14.
[0025] After the vertical reinforcing bar 5 is fixed to the designated position, the support plate 15 needs to be fixed by the horizontal reinforcing bar and the horizontal force-bearing area of the component needs to be increased. At this time, the slider 14 moves through the sliding connection between the slider 13 and the vertical plate 12. When it moves to the fixed position, the screw 16 engages with the slider 14 to fix the slider 14. Since the support plate 15 and the slider 14 are fixedly connected, the support plate 15 is also fixed. Then, the horizontal reinforcing bar is placed above the support plate 15 and contacts the vertical reinforcing bar 5, and then fixed by the steel wire to achieve the effect of easy installation and fixing.
[0026] Among them, a connecting sleeve 17 is sleeved on the outside of the vertical steel bar 5, and a limiting rod 18 is fixedly installed on the outside of the connecting sleeve 17. There are multiple vertical steel bars 5, and all of them are located above the base 1. The limiting rod 18 is located in the middle of two vertical steel bars 5 respectively.
[0027] The main function of the limiting rod 18 is to limit the vertical reinforcing bar 5 to prevent it from swaying back and forth due to the high height of the vertical reinforcing bar 5 and the resulting instability of the center of gravity.
[0028] There are multiple sliders 3, all of which are located inside the base 1, and all of which are slidably connected to the slide groove 2.
[0029] Multiple vertical reinforcing bars 5 are inserted into the interior of multiple sliders 3 respectively. The distance between two vertical reinforcing bars 5 is adjusted by sliding the sliders 3 with the grooves 2 to facilitate positioning.
[0030] There are two vertical plates 12, both of which are located behind the base 1 and are parallel to each other. There are multiple sliders 14 and multiple support plates 15, with the multiple support plates 15 located in front of the two vertical plates 12 respectively.
[0031] Multiple support plates 15 are installed through the sliding connection between multiple sliders 14 and grooves 13, thereby placing multiple horizontal steel bars in fixed positions. While maintaining convenient installation, the horizontal and vertical surfaces can achieve the effect of maximizing the force.
[0032] Working principle and usage process of this utility model:
[0033] Firstly, a groove 2 is provided inside the base 1, and a slider 3 is slidably connected inside the groove 2. A positioning hole 4 is provided inside the slider 3, and a vertical steel bar 5 is inserted into the positioning hole 4. When the vertical steel bar 5 needs to be installed, it is first inserted above the slider 3. Then, the installation is carried out through the sliding connection between the slider 3 and the groove 2, so that the vertical steel bar 5 will be moved to the designated position. When the next vertical steel bar 5 needs to be installed, the position of the vertical steel bar 5 is moved to the designated position and fixed after being judged by the scale 9, so that the distance between each vertical steel bar 5 is equal, thereby achieving the effect of uniform force distribution among multiple vertical steel bars 5 and maximizing the force distribution.
[0034] Finally, after the vertical reinforcing bar 5 is fixed to the designated position, since the support plate 15 needs to be fixed by the horizontal reinforcing bar and the horizontal force-bearing area of the component is increased, the slider 14 moves through the sliding connection between the slider 13 and the vertical plate 12. When it moves to the fixed position, the screw 16 engages with the slider 14 to fix the slider 14. Since the support plate 15 and the slider 14 are fixedly connected, the support plate 15 is also fixed. Then, the horizontal reinforcing bar is placed above the support plate 15 and contacts the vertical reinforcing bar 5, and then fixed by the steel wire to achieve the effect of easy installation and fixing.
