Description

Technical Field

[0001] The utility model relates to the technical field of construction site measuring point protection, in particular to a control network measuring point protection device. Background Art

[0002] Before laying out the building at the construction site, it is necessary to measure the control network and bury the control network measurement points. The conventional practice is to directly cast concrete piers on the existing ground and bury the control network measurement points.

[0003] The expected effect of this method is to use the height of the poured concrete pier to ensure that the control network measuring points are not easily buried by the soil at the construction site to ensure effectiveness. However, since the existing ground elevation often needs to be changed during the construction process, such as backfilling and raising the existing ground, it is easy to cause damage to the control network measuring points, which leads to the need to repeatedly deploy measuring points.

[0004] Among the existing treatment methods, there is a method of using a sealing plate to cover the control network measuring points to protect the control network measuring points, but the treatment method is relatively rough and the sealing plate is easy to shift; there are also some treatment methods that use a cap to cover the control network measuring points, but the cap mainly considers the purpose of closing the control network measuring points, and does not consider whether it can be easily removed later, resulting in conventional cap structures being difficult to remove after being buried in the soil.

[0005] Therefore, a new improvement scheme is needed to improve the current control network measuring point protection device so that it can better protect the control network measuring point on the one hand and can be relatively easily removed in the later stage on the other hand. Utility Model Content

[0006] The utility model aims to address the deficiencies of the prior art and thus provide a control network measuring point protection device which has good protection capability, small removal resistance and is easy to find and open.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a control network measuring point protection device, including a rectangular top plate and four angle irons;

[0008] The rectangular top plate is arranged as a cap top, and the upper surface of the rectangular top plate is a plane;

[0009] The angle of the angle iron is a right angle, one side of the angle iron is fixed to the bottom surface of the rectangular top plate, four angle irons are arranged around the center of the rectangular top plate, and two adjacent angle irons among the four angle irons are perpendicular to each other;

[0010] The other sides of the four angle irons are perpendicular to the rectangular top plate.

[0011] Preferably, the ends of the four angle irons are connected in sequence to form a closed rectangular structure.

[0012] Preferably, the ends of the four angle irons are not arranged adjacent to each other.

[0013] Preferably, one side of the angle iron is welded and fixed to the rectangular top plate.

[0014] Preferably, one side of the angle iron is fixed to the rectangular top plate by bolts.

[0015] Preferably, the area of ​​the rectangular top plate is more than twice the area enclosed by the four angle irons.

[0016] Preferably, the rectangular top plate is a steel plate.

[0017] Preferably, the inner corner of the angle iron is arranged outward.

[0018] Preferably, the top surface of the rectangular top plate is painted with a marking color.

[0019] Preferably, a through hole is provided at the center of the rectangular top plate.

[0020] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model utilizes steel plates and angle irons to be welded or bolted to assemble the control network measuring point protection device. On the one hand, the entire device is in a cap shape, which can protect the control network measuring points from being damaged by on-site construction operations. On the other hand, the rectangular top plate at the top has a large area. When the protection device needs to be removed in the later stage, it is not easy to cause too much removal resistance due to burial problems. Moreover, due to the large area, it is easier to be opened, and the angle iron at the bottom plays a limiting role, which can prevent the protection device from slipping.

[0021] Furthermore, steel plates and angle irons are the most commonly used scraps at construction sites and can be temporarily manufactured at the construction site with simple processes and convenient material acquisition.

[0022] Furthermore, the rectangular top plate is colored and marked to facilitate later finding. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0029] like Figures 1-4 As shown, a control network measuring point protection device includes a rectangular top plate 1 and four angle irons 2.

[0030] The rectangular top plate 1 is provided as a cap top, and the upper surface of the rectangular top plate 1 is a plane. In the present embodiment, the rectangular top plate 1 is made of a steel plate, which is manufactured using leftover materials from a construction site.

[0031] The angle of the angle iron 2 is a right angle, one side of the angle iron 2 is fixed to the bottom surface of the rectangular top plate 1, the inner corner of the angle iron 2 is arranged outward to prevent interference with each other in space, and the four angle irons 2 are arranged around the center of the rectangular top plate 1, and two adjacent angle irons 2 of the four angle irons 2 are perpendicular to each other;

[0032] The other sides of the four angle irons 2 are perpendicular to the rectangular top plate 1 .

[0033] In this embodiment, the ends of the four angle irons 2 are sequentially connected to form a closed rectangular structure, and the entire protective device is in the shape of a cap. One side of the angle iron 2 is welded and fixed to the rectangular top plate 1 to form a whole.

[0034] In this embodiment, the area of ​​the rectangular top plate 1 is more than twice the area enclosed by the four angle irons 2. The area is fully expanded so that when the entire rectangular top plate is buried, the plane area is larger than the longitudinal area. The entire protective device can be easily removed by simply removing the surface loose soil, avoiding the problem of difficulty in removing a cap whose vertical length is greater than its plane length due to lack of force points.

[0035] In other embodiments, the ends of the four angle irons are not arranged adjacent to each other, so the angle irons used can be shorter, saving materials.

[0036] In other embodiments, one side of the angle iron is fixed to the rectangular top plate by bolts, and the fixing methods are various.

[0037] In a preferred embodiment, the top surface of the rectangular top plate is painted with a marking color to facilitate rapid locating of control network measuring points.

[0038] In other embodiments, a through hole is provided at the center of the rectangular top plate, and the protection device can be opened by hooking, providing more operation possibilities.

[0039] When it is necessary to protect the control network measuring points at the construction site, select appropriate steel plates and angle irons from the on-site processed materials for cutting. Obtain square steel plates 1 and connect them to the angle irons 2 by welding. Four angle irons 2 are welded to each square steel plate 1.

[0040] When raising the road surface, first use formwork to support the formwork to protect the control network measuring point 4. After the construction of the newly made road surface 3 is completed, cover the square steel plate 1 over the reserved hole above the control network measuring point 4 for easy daily protection, as Figure 5 shown.

[0041] When it is necessary to use the control network measuring point 4, just uncover the square steel plate 1.

[0042] Finally, it should be noted that: The above has made a detailed description of the preferred embodiment of this patent, but this patent is not limited to the above embodiment. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of this patent.
