[0002] The steel structure column and the foundation are connected through pre-buried bolts in the main body of the building steel structure, and the installation precision of the pre-buried bolts directly affects the steel structure construction precision of the entire factory building. Therefore, the pre-buried installation precision of the pre-buried bolts is very high. If the pre-buried deviation exceeds the allowable range, the hole on the steel column foot plate will not correspond to the foundation bolt, affecting the subsequent main body construction quality of the steel structure. Therefore, a positioning mechanism needs to be used to position the pre-buried bolt during the construction and fixing process of the steel structure pre-buried bolt. SUMMARY

[0011] Example 1: in the construction process of electrolytic workshop steel structure embedded bolt positioning, for the characteristics of many embedded bolts, high precision requirement, use a kind of embedded bolt positioning mould.
[0012] The utility model provides a kind of steel structure pre-buried bolt fast positioning mould, when using, first the longitudinal and transverse axis of concrete structure column cap foundation, structure column template installation boundary line are marked using ink pot, and the midpoint position of concrete structure column is marked using red paint.According to the position of pre-buried bolt 10 on drawing and the relative spacing size between bolt, the processing of positioning template 1 is positioned, and positioning template 1 uses 18mm thick solid wood plywood, and bolt positioning hole 2 is processed using mechanical drilling on positioning template 1, the diameter of bolt positioning hole 2 is pre-buried bolt 10 outer diameter+2mm, square hole 3 is opened in the middle of bolt positioning hole 2, and the size of square hole 3 is 100mm*100mm, and square hole 3 is used for subsequent concrete pouring and vibrating construction.Iron nails are used to fix upper reinforcing beam 4 and lower support beam 5 on the upper side and lower side of positioning template 1 respectively, and upper reinforcing beam 4 and lower support beam 5 are wood square with cross section diameter 40mm*60mm, and upper reinforcing beam 4 and lower support beam 5 are both two, and upper reinforcing beam 4 and lower support beam 5 are perpendicular to each other, and the position is located outside square hole 3 and bolt positioning hole 2, and the distance between iron nails is 70mm~100mm.In the process of steel structure foundation steel bar binding, the position of pre-buried bolt 10 is measured in advance, and the position of pre-buried bolt position conflicts with foundation steel bar is appropriately adjusted to avoid.
[0013] After the installation of pre-buried bolt 10 is completed, the position and elevation are reviewed, and after the review is correct, concrete is poured, and the pouring of concrete is poured from the middle square hole 3 of positioning template 1, and concrete is vibrated during the pouring of concrete to avoid the contact of vibrating rod with pre-buried bolt 10, and if displacement of pre-buried bolt 10 is found during the vibrating process, pre-buried bolt 10 is adjusted, and after adjustment is in place and fixed, concrete is continuously poured.In the process of pouring concrete, plastic sleeve is used to protect the upper thread of pre-buried bolt 10.After the completion of concrete pouring, maintenance is carried out, and after the end of maintenance, positioning template 1 is removed.
