Description

Technical Field

[0001] The invention relates to the field of roof waterproofing construction, and in particular to an adjustable horizontal hole protection cover plate. Background Art

[0002] During the construction process, some small horizontal reserved holes will be generated, including rectangular flue reserved holes (common size 300mm×400mm), wire laying holes (common size 100mm×100mm), pump pipe reserved holes (common size 300mm×300mm), bridge reserved holes (common size 200mm×400mm), etc. According to the construction safety management requirements, such holes need to be blocked.

[0003] There are currently two common ways to seal this type of opening: the first is to use a template to manually cut and process it into a cover slightly larger than the opening according to the size of the opening, and then place it at the opening for protective sealing; the second is to use a template to manually cut and process it into a cover slightly larger than the opening, and add a retaining strip to the template so that the template can be basically guaranteed not to move after being used as a protective seal. The current sealing method can basically prevent objects from falling from the reserved opening and causing objects to hit. However, in the first way of sealing, the sealing template is very likely to move due to contact during construction, and lose its safety protection function. In the second way of sealing, the fixing effect of the sealing template is poor, and it will also move due to contact during construction, and lose its safety protection function. At the same time, both methods require the sealing template to be processed according to the different sizes of the opening, and the template is difficult to classify and recycle after use; therefore, there is an urgent need for an adjustable and reusable horizontal opening protective cover suitable for rectangular openings within a certain range. Summary of the invention

[0004] The present invention aims to provide an adjustable horizontal hole protection cover plate, which is an adjustable protection cover plate for rectangular small holes of different sizes (long and short sides in the range of 100mm-500mm), and meets the requirement that the cover plate is not easy to move. It can reduce the process of processing separate cover plates according to different hole sizes and reduce manual labor. It can be recycled and reused after use, reducing material waste and loss. At the same time, the fixed protection effect is better, and a better safety protection role is played.

[0005] The embodiment of the present invention is achieved as follows:

[0006] An adjustable horizontal hole protection cover plate, the cover plate is provided with a vertical adjustment slot, an adjusting stop bolt is provided in the vertical adjustment slot, the adjusting stop bolt and the vertical adjustment slot are fixed by a nut, the vertical adjustment slot is used to adjust the longitudinal coordinate of the adjusting stop bolt, one end of the adjusting stop bolt is provided with a first fixing nut for abutting against the hole, and the other end is provided with a second fixing nut for limiting fixation with the vertical adjustment slot, the number of the adjusting stop bolts is multiple, and they are clamped in the hole position by the first fixing nut; it is an adjustable protective cover plate for rectangular small holes of different sizes (long and short sides in the range of 100mm-500mm), and meets the requirement that the cover plate is not easy to move, can reduce the process of processing separate cover plates according to different hole sizes, reduce manual work, can be recycled and reused after use, reduce material waste and loss, and at the same time have a good fixing protection effect, and play a good safety protection role. During use, according to the size of the hole, the adjustment bolts are directly installed in appropriate quantities on the cover plate with vertical adjustment slots and adjusted to the appropriate position, and then tightened and fixed. The pull ring is used to place the entire cover plate device at the position of holes of different sizes, thus realizing horizontal protection of the hole. Using this device for protection not only avoids the need for protective processing according to the different sizes of the hole, but also ensures that the protective cover plate is not easily moved, thus achieving a better safety protection effect. At the same time, it can be recycled and reused, thus avoiding the loss and waste of materials.
