Problems solved by technology

However, in the first way of sealing, the sealing formwork is easily displaced due to contact during construction, and loses the safety protection effect
In the second way of blocking, the fixing effect of the blocking formwork is poor, and it will also be displaced due to contact during construction, losing the safety protection effect
At the same time, both methods need to process the plugging formwork according to the different sizes of the opening, and it is difficult to classify and recycle the used formwork; therefore, there is an urgent need for an adjustable reusable horizontal opening suitable for rectangular openings within a certain range protective cover

Embodiment 1

[0025] Example 1: See figure 1 with figure 2 , an adjustable horizontal hole protection cover plate in this embodiment, the cover plate 1 is provided with a vertical adjustment groove 2, and the vertical adjustment groove 2 is provided with an adjustment stop bolt 4, and the adjustment stop bolt 4 and the vertical adjustment groove 2 Fixed by the nut, the vertical adjustment groove 2 is used to adjust the longitudinal coordinates of the adjustment stopper 4, one end of the adjustment stopper 4 is provided with a first fixing nut 43 for resisting the hole, and the other end is provided with a first fixing nut 43 for vertical adjustment. The second fixing nut 41 fixed in the slot 2, the number of adjusting stop bolts 4 is multiple, and the first fixing nut 43 is engaged in the opening; it is used for small rectangular openings of different sizes (long and short sides 100mm-500mm range) ) adjustable protective cover 1, and meet the requirements that the cover 1 is not easy to m...

Embodiment 2

[0026] Embodiment 2: The center position of the cover plate 1 of this embodiment is provided with a pull ring 5 for hanging and pulling the cover plate 1. The number of vertical adjustment grooves 2 in this embodiment is multiple, and they are arranged on the cover plate 1 in parallel. The vertical adjustment slot 2 is fixed. The number of vertical adjustment grooves 2 in this embodiment is four, and the number of adjustment stoppers 4 on each vertical adjustment groove 2 is two. In this embodiment, the vertical adjustment groove 2 is provided with a horizontal sub-groove 3, which is perpendicular to the vertical adjustment groove 2 and communicates with each other. The horizontal sub-groove 3 is used to adjust the horizontal coordinate of the adjustment bolt. In this embodiment, there are multiple transverse sub-slots 3 , which are arranged in parallel on the vertical adjustment slots 2 . The number of transverse sub-grooves 3 in this embodiment is four, and transverse sub-...

Abstract

The invention discloses an adjustable horizontal hole protective cover plate. A vertical adjusting groove is formed in the cover plate, a plurality of adjusting blocking bolts are arranged in the vertical adjusting groove, the adjusting blocking bolts and the vertical adjusting groove are fixed through nuts, and the vertical adjusting groove is used for adjusting the longitudinal coordinates of the adjusting blocking bolts. First fixing nuts used for abutting against the corresponding holes are arranged at one ends of the adjusting blocking bolts, second fixing nuts used for being fixed to the corresponding vertical adjusting groove in a limiting mode are arranged at the other ends of the adjusting blocking bolts, and the multiple adjusting blocking bolts are clamped to the corresponding holes through the first fixing nuts. The adjustable protective cover plate is used for small rectangular holes of different sizes, the requirement that the cover plate is not prone to moving is met, the process of machining the cover plate independently according to the sizes of the holes can be reduced, manual operation is reduced, the cover plate can be recycled after being used, and material waste and loss are reduced; and meanwhile, the fixing and protecting effects are good, and a good safety protection effect is achieved.

Description

technical field [0001] The invention relates to the field of roof waterproof construction, in particular to an adjustable horizontal hole protection cover. Background technique [0002] During the construction process, there will be some small horizontal reserved openings, including reserved openings for rectangular flue (common size 300mm×400mm), setting-out openings (common size 100mm×100mm), reserved openings for pump pipes (common size 300mm ×300mm), bridge reserved openings (common size 200mm ×400mm), etc. According to the construction safety management requirements, such openings need to be blocked. [0003] At present, there are two common sealing methods for such openings: the first one, according to the size of the opening, use a template to manually cut and process it into a cover plate slightly larger than the opening, and then place it at the opening for protection and sealing; the second one, using The formwork is manually cut and processed to be slightly larg...
