Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1 to 3, a group anchor bolt fixing structure comprises a plurality of groups of anchor bolts 1, and an equipment base 3, a colloid irrigation layer 4, a protection tube 5, a supporting frame 6 and a fixing bin 8 which are sequentially arranged from top to bottom, wherein the areas of the equipment base 3 and the colloid irrigation layer 4 can cover the positions of all anchor bolts 1, the protection tube 5 and the fixing bin 8 are respectively in one-to-one correspondence with the anchor bolts 1 and are vertical, two supporting frames 6 which are close to the anchor bolts 1 and are transverse are respectively arranged on two sides of each group of anchor bolts 1, the anchor bolts 1 sequentially penetrate through the equipment base 3 from top to bottom, colloid watering layer 4, protection tube 5, between two supporting brackets 6 and fixed storehouse 8, equipment base 3 is exposed and is compressed tightly equipment base 3 through nut 2 to rag bolt 1 upper end, the lower extreme is located fixed storehouse 8 and is taut two supporting brackets 6 through stationary vane 7.

When positioning and fixing equipment (especially heavy equipment), firstly, a box body formed by a protection pipe 5, a supporting frame 6 and a fixing bin 8 is accurately positioned and then is pre-buried in a foundation, then foundation bolts 1 are positioned and inserted one by one, the foundation bolts 1 enter the fixing bin 8 between the protection pipe 5 and the two supporting frames 6, the foundation bolts 7 are rotated to enable fixing wings 8 to be positioned vertically with the supporting frame 6, then a colloid pouring layer 4 is constructed to play a role of foundation and buffering, finally, an equipment base 3 is positioned and placed, nuts 2 on the foundation bolts 1 are screwed, prestress is formed among the foundation bolts 1, the supporting frame 6 can provide enough locking support for the foundation bolts 1, and therefore the foundation bolts 1 are tightened.

The structure has large stress area inside the foundation, the bearing strength is increased, and the external heavy load borne by a plurality of groups of foundation bolts 1 is completely transmitted to the structure, so that the strength is higher and the foundation is firmer; the fixed bin 8 can be machined, the precision is high, the positioning of the foundation bolt 1 is facilitated, the positioning and the installation are convenient, and the working efficiency of the equipment installation and positioning can be improved; the box that protection tube 5, supporting rack 6 and fixed storehouse 8 formed plays the effect of protection simultaneously to rag bolt 1, and whole rag bolt 1 all is located the inside of this structure, prevents to receive external corruption, increases the security.

As shown in fig. 1 and 2, in the present embodiment, the two support frames 6 of each anchor bolt set 1 are connected by the connecting plate 9, and the connecting plate 9 is distributed on the top surface of the support frame 6 and close to both sides of the protection tube 5 and distributed on the bottom surface of the support frame 6 and close to both sides of the fixing bin 8, so as to further improve the overall structural strength.
