Description

Technical Field

[0001] The utility model relates to the technical field of protective structures, in particular to a patch protective structure. Background Art

[0002] Mechanical and electrical installation is the most complicated and tedious step in an engineering project. In traditional 2D drawings, reserved points and collision points can only be determined based on personal experience, resulting in a lot of rework and waste. BIM technology, especially 3D visualization technology, has changed this phenomenon. It clearly reflects the component information of each mechanical and electrical equipment installed in the installation project on the model, solving the problem of unreasonable installation, but on-site installation construction personnel still need to obtain installation drawing information through drawings. Paper drawings are not only easy to be damaged and lost during use, but also a large number of drawings are not easy to organize, find, and carry in large projects.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] like Figure 1-Figure 4As shown, the patch protection structure of this embodiment includes a base plate 1 and a shielding device 2, the shielding device 2 is arranged inside the base plate 1, the patch 4 is fixed between the base plate 1 and the shielding device 2, the middle part of the base plate 1 protrudes outward to form a hollow boss 11, the side wall of the hollow boss 11 is provided with a protrusion 12, the top of the protrusion 12 abuts against the bottom of the patch 4, the top of the patch 4 abuts against the shielding device 2, and the top of the shielding device 2 extends to the outside of the hollow boss 11; the middle part of the shielding device 2 is a detachable shielding sheet 22.

[0025] A QR code is printed or drawn on the surface of the patch 4. The QR code corresponds to the building component 6 and the BIM (Building Information Model) information. The BIM information includes the name of the building component 6, the position, shape, installation position of the building component 6 in the entire building, and the engineering performance of the component. The BIM information of the patch 4 also includes the name, category, quantity, and construction process information of the electromechanical equipment installed on the building component 6. The patch 4 with the QR code is prefabricated in advance before the building component 6 is shipped to the construction site, and is fixed on the building component 6. In the actual electromechanical installation construction, the construction personnel can obtain the corresponding BIM information by scanning the patch 4, thereby replacing the traditional paper drawings for construction.

[0026] Furthermore, the shielding device 2 includes a fixing ring 21, a shielding sheet 22, a connecting rod 23 and a frame 25. The fixing ring 21 is fixed to the top of the frame 25 and extends to the outside of the hollow boss 11. The shielding sheet 22 is arranged in the middle of the fixing ring 21. The outer wall of the shielding sheet 22 is fixed to one end of a plurality of connecting rods 23, and the other end of the connecting rod 23 is fixed to the inner wall of the fixing ring 21.

[0027] The connecting rod 23 is bent and arched upward, so that the middle shielding piece 22 is higher than the outer ring 21. When the fixing ring 21 is in a stationary state, the shielding piece 22 is pressed downward by hand, and the connecting rod 23 can be quickly broken. After removing the shielding piece, the two-dimensional code pattern on the information patch 4 can be obtained.

[0028] Furthermore, a fracture 24 is formed on the surface of the connecting rod 23 .

[0029] The fracture opening 24 is provided to facilitate breaking of the connecting rod 23 when an external force acts.

[0030] Furthermore, a protective cover 3 is provided outside the shielding device 2 , and the inner wall of the bottom of the protective cover 3 is threadedly connected to the outer wall of the hollow boss 11 .

[0031] In order to prevent the patch 4 from being accidentally damaged and causing confidentiality leakage during transportation, a transparent protective cover 3 is provided on the outside of the hollow boss 11. During transportation, the protective cover 3 can prevent the shielding device 2 from being damaged. After removing the shielding piece 22, the protective cover 3 can still be reinstalled and used to prevent the patch 4 from being contaminated and damaged.

[0032] Furthermore, a mounting hole 13 is opened at the end of the bottom plate 1 , and the bolt 5 passes through the mounting hole 13 and is fixed to the bottom plate 1 and the building component 6 .

[0033] Furthermore, the patch 4 is a waterproof paper sheet, a ceramic sheet, or a metal sheet.

[0034] The method of using the utility model is:

[0035] During installation, the shielding device 2 is first placed into the inner cavity of the hollow boss 11, and then the patch 4 is placed into the inner cavity of the hollow boss 11, so that the two-dimensional code on the patch 4 is blocked by the shielding sheet 22 in the middle of the fixing ring 21, and then the bottom plate 1 including the patch 4 and the shielding device 2 is fixed to the surface of the building component 6 by bolts 5.

[0036] To prevent the patch 4 and the shielding plate 22 from falling out of the hollow boss 11, a wedge-shaped protrusion 12 is provided on the inner side wall of the hollow boss 11. The patch 4 and the shielding device 2 can utilize the gap and extrusion force with the inner wall of the hollow boss 11 to be stuck into the inner cavity of the hollow boss 11 from bottom to top and prevent falling.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
