The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the electric layout plan of certain engineering GIS, basis 1 and post-install 2 shown in this electrical arrangement substantive requirements of form civil Engineering Design Fig. 2, because outdoor GIS equipment may be subject to the effect of the loads such as switch dynamic load, temperature load, wind load, need to be fixed on above concrete foundation, by the GIS electric fixtures strong point the pre-buried embedded part of Fig. 2 and Fig. 1, weld, realize the fixing of GIS electric fixtures in Fig. 1.Traditional construction method requires embedded part pre-buried in advance, because the requirement of GIS construction accuracy is very high, will cause foundation construction complex procedures like this, and the accuracy of embedded part height is also not easy to guarantee.The post-install the utility model proposes and construction method thereof just can address the above problem, and can meet plurality of devices basis requirement, and the height of embedded part can be adjusted, accuracy easily guarantees, working procedure is simple, does not need curing concrete, shortens the duration of construction.Figure 3 shows that top view and elevation after the construction of the utility model embedded part, load reasonably passes on ground by the approach of equipment embedded part steel plate-Mao Shuan – equipment Foundations, and form of structure is reasonable.
As shown in Fig. 4～6, the rearmounted basic embedded part of a kind of assembled height-adjustable, comprising: embedded part steel plate 3, self-locking crab-bolt 4, support nut 5 and conehead nut 6.Manufacturer accurately determines after the model and size of equipment, and quantity, crab-bolt center to center distance and the crab-bolt anchorage length of crab-bolt, within the scope of infrastructure device layout, calculated in the load providing according to manufacturer and embedded part position, selects suitable crab-bolt; According to the position of crab-bolt, to be holed in basis 11 and embedded part steel plate 3, plastics crab-bolt polyethylene sleeve 8 is placed on basic prebored hole 12 inside in advance.According to the requirement of Fig. 3, to crab-bolt and embedded part steel plate, carry out assembled, assembled position relationship schematic diagram as shown in Figure 8, evenly the crab-bolt of whole embedded part is anchored into, with supporting nut 5 and 6 pairs of embedded part steel plates of conehead nut 3, carry out leveling, with level gauge, by designing requirement, adjust the height of each steel plate, evenly screw in crab-bolt until crab-bolt flushes with embedded part steel plate, for requirement attractive in appearance, the bottom filling dry pea gravel concreten 10 to post-install.
The size of A, embedded part steel plate 1
The Main Function of embedded part steel plate is the tie point as equipment.Embedded part steel plate is selected galvanized steel plain sheet, and its length and width meet the Area of bearing that equipment welding can be provided, and it is control that thickness should be take the force request that meets armor plate strength and rigidity, and the thickness of steel plate is advisable with 15mm～20mm.
The spacing of B, anchor hole and boring
The spacing that crab-bolt arranges, unsuitable excessive, if spacing is excessive, may cause the planeness of steel plate influenced, affect attractive in appearance and use; Same spacing is also unsuitable too small, and too small meeting causes the waste of crab-bolt, and according to previous experiences, selecting anchor hole spacing is that 150mm-250mm is advisable.
Determining of C, self-locking crab-bolt length and diameter
Self-locking crab-bolt mainly plays anchoring and fastening, the length of crab-bolt will meet crab-bolt, PE and concrete and form whole anchoring force request, under pulled condition, total length L=45d+L1+L2, d is the diameter of crab-bolt, L1 is the crab-bolt drift that leaks outside, and L2 is the non-anchoring screw segment length of self tapping.By calculating above, choose the finished product crab-bolt of corresponding modulus.Crab-bolt will meet the intensity of tension or pressurized and the requirement of Compression Stability, specific formula for calculation is with reference to the requirement of < < Code for design of steel structures GB50017-2003 > > 5.2.5, the diameter that the diameter of boring is equal to crab-bolt adds 1mm, and the length of boring will meet the requirement that meets crab-bolt anchoring.
D, structure requirement
The concrete minimum intensity grade of former base surface is C25, otherwise should adjust the anchorage length of crab-bolt, and anchorage length really normal root is determined according to field trial.The distance of crab-bolt centre distance edge of foundation is not less than 6d and 70mm.
The equipment data providing in conjunction with producer, determines after the information such as size-spacing of embedded part, crab-bolt and boring, according to the position of crab-bolt, is holed in basis 11 and embedded part steel plate 3, and it is inner that plastics crab-bolt sleeve is placed on infrastructure prebored hole in advance.According to the requirement of Fig. 3, to crab-bolt and embedded part steel plate, carry out assembled, assembled position relationship schematic diagram as shown in Figure 8, evenly the crab-bolt of whole embedded part is anchored into, with supporting nut and conehead nut, embedded part steel plate is carried out to leveling, with level gauge, by designing requirement, adjust the height of embedded part steel plate, evenly screw in crab-bolt until crab-bolt end face flushes with the end face of embedded part steel plate.
The embodiment flow process of basis embedded part is:
1) load providing according to manufacturer and embedded part position, Deng manufacturer, accurately determine after the model and size of equipment, embedded part steel plate 3 sizes that design scheme combining is definite, quantity, crab-bolt center to center distance and the crab-bolt anchorage length of calculating crab-bolt, select suitable crab-bolt;
2) in conjunction with the scheme of design, determine embedded part scope, according to the position of crab-bolt, holed in basis and embedded part steel plate, plastics crab-bolt sleeve is placed on infrastructure prebored hole 12 inside in advance.
3) according to the requirement of Fig. 3, to crab-bolt and embedded part steel plate, carry out assembled, assembled position relationship schematic diagram as shown in Figure 8, evenly the crab-bolt of whole embedded part is anchored into, with supporting nut 5 and 6 pairs of embedded part steel plates of conehead nut 3, carry out leveling, concrete leveling step is as follows: first with spanner, regulate all support nut height above steel plate, coarse regulation steel plate embedded part is to design elevation; Then with annular conehead nut runner 9 aligning 7 pairs, hole of conehead nut double card conehead nuts 6, regulate and screw, to support nut 5 and conehead nut 6, block embedded part steel plate 3, with level gauge, by designing requirement, evenly inching is up and down carried out in the position of all support nuts 5 and conehead nut 6, the height of fine setting embedded part steel plate 3 is until design elevation; Finally evenly screw in crab-bolt until the end face of crab-bolt is concordant with the end face of embedded part steel plate, and realize the self-locking of self-locking crab-bolt.If the height of embedded part steel plate is improper, the height that can support nut and conehead nut by adjusting just can be realized the inching up and down of embedded part steel plate height.
4) for requirement attractive in appearance, at the bottom of post-install filling dry pea gravel concreten 10, exposed parts press polish, the height of filling dry pea gravel concreten is the height between embedded part and former base surface.
The working procedure such as design and installation embedded part needn't wait equipment manufacturer's working drawing data like this, does not affect the duration of whole engineering construction, is also conducive to first phase and distant view engineering is selected equipment flexibly.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present utility model is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
