Abstract
The utility model relates to a floor drain pipe opening protection pier which is used for solving the problem of potential safety hazards existing in an existing floor drain pipe opening. The protection pier comprises a pier cover, arc-shaped elastic sheets and an expansion bolt. A T-shaped threaded hole is formed in the center of the pier cover. The arc-shaped elastic sheets are located under the pier cover and circumferentially and evenly fixed around the T-shaped threaded hole. The upper end of the expansion bolt is provided with threads, the lower end of the expansion bolt is provided with a pear-shaped head, and the expansion bolt is installed on the T-shaped threaded hole. After the floor drain pipe opening protection pier is installed, the arc-shaped elastic sheets are tightly pressed between a floor and the expansion bolt, the stability is improved, and the problem of potential safety hazards is avoided whatever construction is conducted upstairs or downstairs.
Description
Technical field
The utility model relates to construction safety protection instrument, what be specifically related to is a kind of underfloor hose nozzle Protection Pier.
Background technology
Job site is on the floor of levels, all leave sewer pipe mouth, all there is certain potential safety hazard for construction under upstairs house in this sewer pipe mouth, while construction, must prevent from not looking the sewer pipe mouth of stepping on upstairs, while construction downstairs, must prevent from sewer pipe mouth drop some construction fragments, somebody is even blocked with discarded cement sack, because the steadiness of sack is poor, step on or easily cause danger and damage, therefore, for ensureing the safety of job site, need to design a kind of device that can improve safety.
Utility model content
Goal of the invention of the present utility model is to provide a kind of underfloor hose nozzle Protection Pier for the problems referred to above, for solving the problem of the potential safety hazard that current underfloor hose nozzle exists.
The utility model is achieved through the following technical solutions: underfloor hose nozzle Protection Pier comprises Dun Gai, arc spring lamination, dilating screw, and wherein, Dun Gai center has inverted "convex" shape screwed hole; Arc spring lamination is positioned at the below of Dun Gai, and is circumferentially evenly fixed on around inverted "convex" shape screwed hole; Dilating screw upper end is provided with screw thread, and lower end is set to pear-shaped heads, and dilating screw is arranged on inverted "convex" shape screwed hole.
Described dilating screw top is provided with circular lid, and circular lid inside is provided with equilateral triangle groove.
No matter adopt the good effect of technique scheme: after the utility model is installed, arc spring lamination is crushed between floor and dilating screw tightly, and steadiness is improved, be upstairs or downstairs to construct, and do not had the problem of potential safety hazard.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of dilating screw in the utility model.
In figure: 1 Dun Gai, 2 arc spring laminations, 3 dilating screws, 4 inverted "convex" shape screwed holes, 5 circular lid, 6 equilateral triangle grooves.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Fig. 1 is structural representation of the present utility model, and as shown in Figure 1, underfloor hose nozzle Protection Pier comprises pier lid 1, arc spring lamination 2, dilating screw 3.Wherein, pier lid 1 center has inverted "convex" shape screwed hole 4.Arc spring lamination 2 is positioned at the below of pier lid 1, and is circumferentially evenly fixed on around inverted "convex" shape screwed hole 4.The minimum number of arc spring lamination is three, is conventionally set to four arc spring laminations.Dilating screw 3 upper ends are provided with screw thread, and lower end is set to pear-shaped heads, and dilating screw 3 is arranged on inverted "convex" shape screwed hole 4.
Fig. 2 is the plan structure schematic diagram of dilating screw in the utility model, as shown in Figure 2, and for further increasing steadiness, and safety, dilating screw 3 tops can be arranged to a circular lid 5, and in circular lid 5 inside, equilateral triangle groove 6 is set.The setting of equilateral triangle groove, can only be used special triangular tool while making to rotate dilating screw, has therefore increased safety.
After the utility model is installed, arc spring lamination is crushed between floor and dilating screw tightly, and steadiness is improved, and no matter is upstairs or downstairs to construct, and has not had the problem of potential safety hazard.
