Abstract
The invention discloses a reusable reserved hole protection device. The device comprises a rectangular frame, protection cover plates are arranged on the frame, two fixed rods are arranged in the frame, a fastening apparatus is arranged on the fixed rods and comprises a rocking bar and drive shafts arranged at two ends of the rocking rod, threads are arranged on the drive shafts, sleeves are sleeved on the outside of the drive shafts, internal threads matched with the threads on the drive shafts are arranged on the sleeves, and the sleeves is fixed on the fixing rods in a horizontal movable mode. The device is simple to manufacture and mount, the sleeves on the drive shafts on two sides can be slidden outwards until reaching concrete edges of two sides of a reusable hole by rocking the middle rocking bars, so that the protection device cannot move at random, the protection efficacy is high, the device can be operated completely by one person. By the aid of the protection cover plates, releasing of the protection state is facilitated.
Description
Technical field
The present invention relates to a kind of protector, specifically a kind of reusable hole to be provided protector.
Background technology
Can reserve a lot of reserved openings in building operations main body stage floor, and the protection of reserved opening is to be difficult to process thorough common fault construction period always, the hole to be provided protected tends to be lost because the work short time need to be removed fully protective action.And be the safety that guarantees engineering, must drop into a large amount of manpower and materials, the protection of constantly removing to repair hole to be provided, this just causes the expenses of personnel and material.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of reusable hole to be provided protector, and this installs easy installation and removal, reusable.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of reusable hole to be provided protector, it comprises rectangular shaped rim, be provided with protective cover plate on described frame, be provided with two fixed bars in frame, be provided with fastener on described fixed bar, described fastener comprises rocking bar and is arranged on the driving shaft at rocking bar two ends, be provided with screw thread on described driving shaft, driving shaft is outside equipped with sleeve pipe, described sleeve pipe is provided with the internal thread matched with screw thread on driving shaft, and described sleeve pipe can be fixed on fixed bar with moving horizontally.
Described cannula tip is provided with flexible part, for pressing closer the both sides concrete.
Apparatus of the present invention are made simple, install simply, utilize intermediate rocker to shake, and just the sleeve pipe on two side drive axles outwards can be slided, until hold out against hole to be provided two side concrete edges, make it arbitrarily to move, and the protection effect is very high, but only just complete operation of a people; The protective cover plate that this device arranges is convenient to hole to be provided need remove the protection state, as transmitted after the work such as thing complete, can recover protective action.
Traditional approach is removed after the hole to be provided protection and is often needed again to drop into manpower material etc. and again protect.Can greatly reduce the maintenance cost to the hole to be provided protection after adopting the protection of this device.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is top view of the present invention.
Fig. 2 is front view of the present invention.
The specific embodiment
As shown in Figure 1, 2, reusable hole to be provided protector comprises rectangular shaped rim 1, on described frame 1, is provided with protective cover plate 2, when needs are used hole to be provided, can open protective cover plate 2; While not needing, can directly protective cover plate 2 be covered.
Be provided with two fixed bars 3 in frame 1, on described fixed bar 3, be provided with fastener, the purpose of fastener setting is that this protector is fixed on to reserved opening, prevents random movement.
Described fastener comprises rocking bar 4 and is arranged on the driving shaft 5 at rocking bar 4 two ends, be provided with screw thread on described driving shaft 5, driving shaft is outside equipped with sleeve pipe 6, described sleeve pipe 6 is provided with the internal thread matched with screw thread on driving shaft 5, described sleeve pipe 6 can be fixed on fixed bar 3 with moving horizontally, described sleeve pipe 6 tops are provided with flexible part 7, for pressing closer both sides concrete 8.
During use, hand rocking bar 4, under the effect of rocking bar 4, driving shaft 5 rotates, and due to the effect of screw thread, sleeve pipe 6 moves to two ends in the horizontal direction, until sleeve pipe 6 two ends withstand on hole to be provided two side concrete 8 edges, thereby protector integral body is fixed on to reserved opening, plays protective action.
Above-described embodiment does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
