Abstract
The utility model relates to an adjustable hole protective cover plate belongs to the interim hole of building trade protection technical field, including cover the body, at least three group's adjusting parts are arranged along circumference in lid body back center, and the adjusting part comprises stopper, threaded rod, preceding nut and back nut, and on nut, back nut were worn to adorn in the front to stopper connecting thread pole, threaded rod, it is central that the body is covered in each threaded rod sensing. The utility model discloses effectively protect the hole, the needs of the safe construction of not only being convenient for improve the safe standard of civilization level of construction, can use repeatedly in the engineering of difference moreover, have avoided the material extravagant.
Description
Technical field
The utility model relates to a kind of adjustable hole protective cover plate, belongs to building trade temporary aperture guard technology field.
Background technology
In building trade, during site operation, often need to beat various hole, because job site hole is many, densely populated place, hole location are not obvious, be often easily left in the basket, thus it is injured to cause personnel to fall into.Therefore, the hole of job site needs to install interim cover plate additional, and hole cover plate many infinite places measure in the past, during use, cover plate is easily moved, cause hole to expose, do not reach protection effect, some installs the cover plate of limiting plate additional, because limiting plate directly welds on the cover board, therefore, can only use for the hole of correspondingly-sized, cause the waste of material.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: provide a kind of adjustable hole protective cover plate, hole is effectively protected, not only be convenient to the needs of safe construction, improve the security civilization standardization of construction, and can in different engineerings Reusability, avoid waste of material.
Adjustable hole protective cover plate described in the utility model, comprise lid body, center, the lid body back side is at least three group adjusting parts circumferentially, adjusting part is made up of limited block, threaded rod, front nut and back nut, limited block connecting thread bar, threaded rod is installed on front nut, back nut, and each threaded rod points to lid body central.
Lid body adopts checkered steel plate to make, intensity meets the demands, nut, back nut two groups of nuts before the welding of the cover plate back side, by the position of rotating threaded rod and adjustable limited block, thus the covering of multiple different size hole can be applicable to, the fastening effect of threaded rod avoids and to be shifted the potential safety hazard caused in construction cover plate, eliminates safe common fault.
Described adjusting part arranges four groups, transversely, two groups of longitudinal each symmetrical arrangement.
Described limited block is square.
The described lid body back side is provided with handle and ring stiffener.
During use, rotate each group of threaded rod, according to the position of the size adjusting limited block of hole, cover on hole by lid body, limited block blocks hole edge automatically, and when lid body moves, limited block can block automatically, prevents displacement.The fastening effect of threaded rod avoids and to be shifted the potential safety hazard caused in construction cover plate, eliminates safe common fault.When pulling down, by handle by the pull-up of lid body, readjust the position of limited block, different holes can be reused for.
Compared with prior art, the beneficial effect that the utility model has is:
This adjustable hole protective cover plate effectively protects hole, is not only convenient to the needs of safe construction, improves the security civilization standardization of construction, and can in different engineerings Reusability, avoid waste of material.

In figure: 1, lid body; 2, adjusting part; 2.1, limited block; 2.2, threaded rod; 2.3, front nut; 2.4, back nut; 3, reinforcing rib; 4, handle.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, this adjustable hole protective cover plate comprises lid body 1, center, lid body 1 back side is at least three group adjusting parts 2 circumferentially, preferred arrangements four groups, transversely, two groups of longitudinal each symmetrical arrangement, adjusting part 2 is made up of limited block 2.1, threaded rod 2.2, front nut 2.3 and back nut 2.4, limited block 2.1 is square, limited block 2.1 connecting thread bar 2.2, threaded rod 2.2 is installed on front nut 2.3, back nut 2.4, and each threaded rod 2.2 points to lid body 1 center.
Lid body 1 back side is provided with handle 4 and ring stiffener 3, and ring stiffener 3 is to lid body 1 booster action.
The course of work:
During use, rotate each group of threaded rod 2.2, according to the position of the size adjusting limited block 2.1 of hole, cover on hole by lid body 1, limited block 2.1 blocks hole edge automatically, and when lid body 1 moves, limited block 2.1 can block automatically, prevents displacement.The fastening effect of threaded rod 2.2 avoids and to be shifted the potential safety hazard caused in construction cover plate, eliminates safe common fault.When pulling down, by handle 4 by lid body 1 pull-up, readjust the position of limited block 2.1, different holes can be reused for.
