Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Example 1: as shown in fig. 1-9, an adjustable and fixed hole protection device is used for protection operation of reserved holes between adjacent floors in the construction process of constructional engineering, as shown in fig. 1-4, the device comprises a protection plate 1 which is located on the upper side of a hole and has an area larger than that of the hole, the protection plate 1 is a metal steel plate, the thickness of the protection plate 1 is larger than or equal to 0.5cm, the protection plate is guaranteed not to bounce down after a worker steps on the protection plate, at least two transverse adjusting empty grooves 3 are formed in the protection plate 1, and at least one L-shaped barb member 2 is sleeved inside each adjusting empty groove 3.
L shape barb piece 2 includes vertical pole 201 and horizon bar 202, the horizon bar 202 of two L shape barb pieces 2 is respectively outwards turned over and is perpendicular with vertical pole 201, make horizon bar 202 as its terminal directional reservation mouthful lateral wall one side of barb bar, vertical pole 201 is the screw rod, vertical pole 201 inserts and adjusts inside the dead slot 3, and vertical pole 201 outside cover is equipped with two at least fixation nut 4, two fixation nut 4 are located the both sides of guard plate 1 respectively, and be equipped with gasket 5 in one side that fixation nut 4 is located guard plate 1, gasket 5 is the circular gasket, and the diameter of gasket 5 is greater than the width of adjusting the dead slot 3, when using, fixation nut 4 and the gasket 5 of guard plate 1 bottom side are for playing the spacing effect under the restriction, do not play fixed effect.
