Abstract
The utility model discloses a kind of special temporary facility ground networks, it includes the building frame (1) of board house, below ground in building frame (1) bottom sets horizontal earth mat (3), is provided with vertical wire (2) in the corner of the building frame (1) and is connected to form equal pressure zone with horizontal earth mat (3).Be connected to ground networks on temporary facility by the utility model, when temporary facility in there is high-voltage electric shock, too high electric current can be imported the earth by temporary facility, as long as the people in temporary facility does not contact ironwork, just will not be influenceed by electric current, carry out the safety of guarantor with this, can play a part of to carry out security protection to the people in temporary facility under high-tension electricity.
Description
Technical field
The utility model is related to temporary facility technical field in construction, and in particular to a kind of temporary facility grounded screen
Network.
Background technology
With developing rapidly for China's infrastructure construction, real estate cause is maked rapid progress, it is necessary in different environments
Building construction is carried out, according to different geographical conditions, construction is needed due to construction, and narrow field is run into sometimes, will be faced
When facility build in specific position；And situation about this time running into is aiming at having high-tension electricity dangerous in temporary facility is built
Position when, for such case, we must just take grounded screen special in one to be connected with temporary facility, to temporary facility
Safety necessarily processed.
Utility model content
The purpose of this utility model is to provide a kind of special temporary facility ground networks, to solve in some particular surroundings
The security protection problem of the temporary facility of lower build, can play carries out security protection under high-tension electricity to the people in temporary facility
Effect.
The technical solution of the utility model is as follows：
The utility model is such a temporary facility ground networks structure, and it includes the building frame of board house, is built at this
The horizontal earth mat of below ground setting of base of frame is built, be provided with vertical wire in the corner of the building frame connects with horizontal earth mat
Connect to form equal pressure zone.
Wherein, the horizontal earth mat is made up of 40 × 4 band irons, and the buried depth of horizontal earth mat is at least up to 1m, horizontal earth mat
The outer 0.8~1.2m wide of length-width ratio building frame.The vertical wire is made up of 40 × 4 band irons, vertical wire and horizontal earth mat
It is weldingly connected.The grounding resistance of the ground networks that building frame, vertical wire are constituted with horizontal earth mat is less than 4 Ω.
Be connected to ground networks on temporary facility by the utility model, when temporary facility in there is high-voltage electric shock, temporarily
Too high electric current can be imported the earth by facility, as long as the people in temporary facility does not contact ironwork, just will not be influenceed by electric current, with
This carrys out the safety of guarantor, can play a part of to carry out security protection to the people in temporary facility under high-tension electricity.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Mark in accompanying drawing for：1- building frames, the vertical wires of 2-, the horizontal earth mats of 3-.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, this ground networks structure of the invention includes the building frame 1 of board house, at the bottom of building frame 1
The below ground in portion sets horizontal earth mat 3, is provided with vertical wire 2 in the corner of the building frame 1 and is connected shape with horizontal earth mat 3
Into equal pressure zone.Horizontal earth mat 3 is made up of 40 × 4 band irons, and the buried depth of horizontal earth mat 3 is at least up to 1m, the length and width of horizontal earth mat 3
Wide 0.8~1.2m outer than building frame 1.Vertical wire 2 is made up of 40 × 4 band irons, and vertical wire 2 welds phase with horizontal earth mat 3
Even.The grounding resistance of the ground networks that building frame 1, vertical wire 2 are constituted with horizontal earth mat 3 is less than 4 Ω.
The utility model is implemented：As shown in figure 1, carrying out excavation foundation trench first, 40 × 4 band irons composition is laid
Horizontal earth mat 3, after 40 × 4 band irons vertical wire 2 of composition is welded with horizontal earth mat 3, backfills and assembles board house building frame 1,
After the completion of, building frame 1 is welded with vertical wire 2, make building frame 1, vertical wire 2 and horizontal earth mat 3 whole as one
Body, grounding resistance is measured less than 4 Ω with ground meter.The horizontal earth mat 3 is made up of 40 × 4 band irons, and horizontal earth mat 3
Buried depth need to meet 1m, and the outer width 1m of length-width ratio building of horizontal earth mat 3 is advisable.
When vertical wire 2 weld with horizontal earth mat 3, length is not not less than 60mm, during single-sided welding for length during two-sided welding
Less than 120mm, when two weldering band irons are in 90 °, lap-welded round steel should bend to 90 ° of circular arc type and carry out overlap welding, overlap welding list
Edge lengths are not less than 100mm, and weld seam must be full during welding.
Certainly, it is more than concrete application example of the present utility model, the utility model also has other implementation methods, all
The technical scheme formed using equivalent or equivalent transformation, is all fallen within the protection domain required by the utility model.
