Description

Technical Field

[0001] The present application relates to the technical field of prefabricated trench cover paving, and in particular to a limiter for installing and positioning prefabricated concrete trench cover. Background Art

[0002] During the cable trench construction process, after installing the cable support on the inner wall of the cable trench, the cables are laid on the cable support. Finally, several cable trench covers are installed on the upper sinking platform of the cable trench along the length of the cable trench to protect the cables. There are many types of cable trench covers. In terms of material, commonly used cable trench covers include cast iron covers, concrete covers, composite covers, fiberglass covers, etc.

[0003] During the installation of cable trench covers, it is usually necessary to maintain a gap between adjacent cable trench covers to allow rainwater to flow into the cable trench and into the municipal drainage pipes, thus providing drainage for the cable trench. However, during the installation of cable trench covers, it is difficult to ensure the consistency of the installation gap width between adjacent cable trench covers, requiring repeated adjustments to the position of the cable trench covers, resulting in low construction efficiency and a need for further improvement. Utility Model Content

[0004] In order to improve the laying efficiency of precast cover slabs, the present application provides a limiter for installation and positioning of concrete precast cover slabs.

[0005] The present application provides a stopper for installation and positioning of a prefabricated concrete cover plate, which adopts the following technical solution:

[0006] A limiter for installing and positioning a concrete prefabricated cover plate comprises a limiter body, wherein the limiter body comprises a limiter horizontal plate and a limiter vertical plate arranged on the limiter horizontal plate, wherein the upper end face of the limiter horizontal plate is provided with a handle, and the lower end face of the limiter horizontal plate is used to abut against the upper end face of the prefabricated cover plate, and the outer walls on both sides of the limiter vertical plate abut against the side walls of the two prefabricated cover plates respectively.

[0007] By adopting the above technical solution, in the process of laying the prefabricated cover plates, after the first prefabricated cover plate is laid, the limiting horizontal plate is abutted against the upper end face of the prefabricated cover plate, and one side outer wall of the limiting vertical plate is abutted against the side wall of the first prefabricated cover plate, and then the second prefabricated cover plate is placed on the sinking platform of the cable trench, and the second prefabricated cover plate is pushed to slide toward the direction close to the first prefabricated cover plate, so that its side wall abuts against the other side outer wall of the limiting vertical plate, and then the construction personnel apply force to the limiting horizontal plate through the handle to extract the limiter body upward, and after the limiting vertical plate is pulled out, the limiter body is placed on the other side of the second prefabricated cover plate, and the next prefabricated cover plate is laid to ensure the consistency of the spacing between adjacent prefabricated cover plates and improve the laying efficiency of the prefabricated cover plates.

[0008] Preferably, both side outer walls of the position-limiting vertical plate are provided with balls, and the outer peripheral walls of the balls abut against the side walls of the prefabricated cover plate.

[0009] By adopting the above technical solution, the balls are arranged on the outer walls on both sides of the limiting vertical plate, and the outer peripheral walls of the balls are in contact with the side walls of the prefabricated cover plate. The presence of the balls significantly reduces the friction between the limiting vertical plate and the prefabricated cover plate, making it easier to remove the limiting vertical plate and avoiding scratches or damage caused by hard contact.

[0010] Preferably, one side outer wall of the limiting horizontal plate is flush with the outer side wall of the limiting vertical plate, so that the cross section of the limiter body is in an inverted L shape.

[0011] By adopting the above technical solution, the cross-section of the limiter body is set in an inverted L shape, and the limiter body is directly hooked on the first prefabricated cover plate, so that the limiter horizontal plate abuts against the upper end face of the prefabricated cover plate, and one side outer wall of the limiter vertical plate abuts against the side wall of the first prefabricated cover plate. The outer wall of one side of the limiter horizontal plate is flush with the outer side wall of the limiter vertical plate, ensuring that the second prefabricated cover plate slides into place smoothly, that is, the side wall of the second prefabricated cover plate abuts against the other side outer wall of the limiter vertical plate.

[0012] Preferably, the limiting vertical plate is detachably connected to the limiting horizontal plate.

[0013] By adopting the above technical solution, the limiting vertical plate can be detachably connected to the limiting horizontal plate, so that the limiter body can be flexibly replaced with limiting vertical plates of different thicknesses according to actual usage requirements, thereby improving the applicability and flexibility of the limiter.

[0014] Preferably, a first slide groove is provided on the lower end surface of the limiting horizontal plate, and a notch at one end of the first slide groove extends to the side wall of the limiting horizontal plate, so that one end of the first slide groove is an open end and the other end of the first slide groove is a closed end, and a sliding protrusion is fixed on the upper end surface of the limiting vertical plate and is slidably inserted into the first slide groove, and the limiting horizontal plate is provided with a control component for controlling the opening and closing of the first slide groove.

[0015] By adopting the above technical solution, the design of the first slide groove facilitates the installation and removal of the limit vertical plate, improving construction efficiency. The presence of the control member effectively prevents the sliding protrusion from accidentally falling off during use, ensuring the stability of the limiter.

[0016] Preferably, the control member includes a sealing plate slidably connected to the side wall of the limiting horizontal plate, and the sealing plate slides to the open end of the first sliding groove to prevent the sliding protrusion from sliding out of the first sliding groove.

[0017] By adopting the above technical solution, the closing plate is slidably connected to the side wall of the limiting horizontal plate. When the closing plate slides to the open end of the first slide groove, it can effectively prevent the sliding protrusion from sliding out of the first slide groove, thereby realizing a stable connection between the limiting vertical plate and the limiting horizontal plate, ensuring the stability of the limiter during use, and avoiding accidental falling off of the limiting vertical plate.

[0018] Preferably, the control member further comprises a spring arranged between the limiting horizontal plate and the sealing plate, and the spring forces the sealing plate to slide to the open end of the first sliding groove under normal conditions.

[0019] By adopting the above technical solution, the spring forces the closing plate to slide to the open end of the first slide groove under normal conditions, effectively preventing the limiting vertical plate from accidentally sliding out of the first slide groove, and ensuring the stability and reliability of the limiter during use.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. During the process of laying the prefabricated cover plate, after the first prefabricated cover plate is laid, the limiting horizontal plate is abutted against the upper end surface of the prefabricated cover plate, and one side outer wall of the limiting vertical plate is abutted against the side wall of the first prefabricated cover plate. Then, the second prefabricated cover plate is placed on the sinking platform of the cable trench, and the second prefabricated cover plate is pushed to slide toward the first prefabricated cover plate, so that its side wall abuts against the other side outer wall of the limiting vertical plate. Then, the construction personnel apply force to the limiting horizontal plate through the handle to extract the limiter body upward. After the limiting vertical plate is pulled out, the limiter body is placed on the other side of the second prefabricated cover plate, and the next prefabricated cover plate is laid to ensure the consistency of the spacing between adjacent prefabricated cover plates and improve the laying efficiency of the prefabricated cover plates.

[0022] 2. The limit vertical plate can be detachably connected to the limit horizontal plate, so that the limiter body can be flexibly replaced with limit vertical plates of different thicknesses and sizes according to actual use requirements, thereby improving the application range and flexibility of the limiter.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] Example 1:

[0030] The embodiment of the present application discloses a stopper for installing and positioning a prefabricated concrete cover plate, referring to Figure 1 、 Figure 2 The stopper body 10 includes a plurality of stopper bodies 10, each including a stopper horizontal plate 1 and a stopper vertical plate 2 disposed on the stopper horizontal plate 1. In this embodiment, the stopper vertical plate 2 is fixedly connected to the lower end surface of one side of the stopper horizontal plate 1, and the outer wall of one side of the stopper horizontal plate 1 is flush with the outer wall of the stopper vertical plate 2, so that the cross section of the stopper body 10 is inverted L-shaped. The lower end surface of the stopper horizontal plate 1 is used to abut the upper end surface of the prefabricated cover plate 20, and the outer walls of the two sides of the stopper vertical plate 2 respectively abut the side walls of the two prefabricated cover plates 20.

[0031] Ball bearings 4 are provided on both side outer walls of the limiting vertical plate 2 , and the outer peripheral walls of the ball bearings 4 abut against the side walls of the prefabricated cover plate 20 . A handle 3 is fixedly connected to the upper end surface of the limiting horizontal plate 1 .

[0032] The implementation principle of a limiter for installing and positioning a prefabricated cover plate 20 in an embodiment of the present application is as follows: in the process of laying the prefabricated cover plate 20, after the first prefabricated cover plate 20 is laid, the limiting horizontal plate 1 is abutted against the upper end surface of the prefabricated cover plate 20, and the outer wall of one side of the limiting vertical plate 2 is abutted against the side wall of the first prefabricated cover plate 20, and then the second prefabricated cover plate 20 is placed on the sinking platform of the cable trench, and the second prefabricated cover plate 20 is pushed to slide toward the first prefabricated cover plate 20, so that its side wall abuts against the outer wall of the other side of the limiting vertical plate 2, and then the construction personnel apply force to the limiting horizontal plate 1 through the handle 3 to extract the limiter body 10 upward, and after the limiting vertical plate 2 is pulled out, the limiter body 10 is placed on the other side of the second prefabricated cover plate 20, and the next prefabricated cover plate 20 is laid to ensure the consistency of the spacing between adjacent cable protection cover plates and improve the laying efficiency of the prefabricated cover plates.

[0033] Example 2:

[0034] The difference from Example 1 is that, referring to Figure 3 、 Figure 4The limiting vertical plate 2 is detachably connected to the limiting horizontal plate 1. In other embodiments, the limiting vertical plate 2 is detachably connected to the limiting horizontal plate 1 via bolts. In this embodiment, a first chute 11 is formed on the lower end surface of one side of the limiting horizontal plate 1. One end of the first chute 11 extends from the outer wall of one side of the limiting horizontal plate 1, such that one end of the first chute 11 is open and the other end of the first chute 11 is closed. A sliding protrusion 21 is fixed on the upper end surface of the limiting vertical plate 2 and is slidably inserted into the first chute 11.

[0035] A second slide groove 12 is provided on the outer side wall of the limiting horizontal plate 1 located at the open end of the first slide groove 11. The limiting horizontal plate 1 is provided with a control component 5 for controlling the opening and closing of the first slide groove 11. The control component 5 includes a movable plate 51 slidably connected to the second slide groove 12, a sealing plate 52 fixedly connected to the movable plate 51, and a spring 53 arranged between the movable plate 51 and the limiting horizontal plate 1. One end of the spring 53 is fixedly connected to the movable plate 51, and the other end of the spring 53 is fixedly connected to the outer wall of the limiting horizontal plate 1. Under normal circumstances, the spring 53 forces the sealing plate 52 to slide to the open end of the first slide groove 11 to prevent the sliding protrusion 21 from sliding out of the first slide groove 11.

[0036] The implementation principle of the embodiment of the present application is as follows: when the limit vertical plate 2 needs to be replaced, a force is applied to the movable plate 51, driving the closing plate 52 to slide in the direction close to the spring 53, so that the opening of the first slide groove 11 is in an open state. At this time, the spring 53 undergoes elastic deformation and has elastic potential energy, which can slide and withdraw the sliding protrusion 21, thereby replacing the limit vertical plate 2. The replaced limit vertical plate 2 is slid from the opening of the first slide groove 11 and inserted into the first slide groove 11 again. Then, the force applied to the movable plate 51 is removed, and the spring 53 elastically resets to force the closing plate 52 to slide to the open end of the first slide groove 11, effectively preventing the sliding protrusion 21 from sliding out of the first slide groove 11, thereby realizing a stable connection between the limit vertical plate 2 and the limit horizontal plate 1, ensuring the stability of the limiter during use, and avoiding accidental falling off of the limit vertical plate 2.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
