Abstract
The utility model discloses a novel foundation bolt set which comprises a plurality of foundation bolts and a fixing plate group, wherein the fixing plate group consists of an upper-layer fixing plate, a middle-layer fixing plate and a lower-layer fixing plate; the three layers of the fixing plates are completely the same in size and structure, and all adopt a square structure; an angle bolt hole is formed in each corner of each layer of the fixing plate; the connection lines of the circle centers of the four angle bolt holes are connected into a small square; a central bolt hole is formed in the central position of the fixing plate; four bolt holes are uniformly formed in a circle which takes the central position of the fixing plate as the center; the sizes of the bolt holes are completely the same; the sum of the diameter of the circle and the diameter of each bolt hole is equal to the side length of the small square. The foundation bolt set adopts the fixing plate group as a carrier on which a plurality of foundation bolts are fixedly supported, the foundation bolts are fixed together through the upper-layer fixing layer, the middle-layer fixing plate and the lower-layer fixing plate to form a foundation bolt cage, and the number of the foundation bolts is identical to that of the bolt holes, so that a novel foundation bolt set is organically formed, and both the mounting precision of the bolts is ensured and the mounting operation is convenient and rapid.
Description
Technical field:
The utility model relates to a kind of Novel feet bolt group, belongs to transformer substation framework foundation frame high accuracy pre-embedded anchoring bolts mounting technique field.
Background technology:
Along with the fast development of Chinese national economy, the quickening of the infrastructure construction speed such as power plant, power transmission and transformation institute (station), steel framework factory building, all kinds of bases especially pre-embedded anchoring bolts of equipment Foundations are adopted in a large number, compared with conventional house building, the base specification of this class building is many, quantity large and it is high that accuracy requirement is installed, once indivedual bolt embedments have occurred that relatively large deviation, by directly affecting the installation and debugging of equipment, will have a strong impact on construction speed, increase engineering cost.
Utility model content:
Technical problem to be solved in the utility model is: a kind of Novel feet bolt group is provided, solves stone bolt the problem that complexity is slow, precision is low is installed.
The technical scheme that the utility model is taked for technical solution problem is:
A kind of Novel feet bolt group, comprises multiple stone bolt and fixed head group, and described fixed head group is made up of upper strata fixed head, middle level fixed head and lower floor's fixed head, and three layers of fixed head size structure are in full accord, are all square structure; Be provided with a corner bolt hole at the corner location of every layer of fixed head, the circle center line connecting in four corner bolt holes forms a little square, be provided with a centre bolt hole in the center of fixed head, on the circle taking fixed head center as the center of circle, be evenly provided with 4 bolts hole, described diameter of a circle is slightly less than the little foursquare length of side.
4 bolts hole that described four corner bolt holes, centre bolt hole, circle evenly arrange above, the size of these bolts hole is in full accord, and the diameter that described diameter of a circle adds upper bolt hole equals the little foursquare length of side.
On the outer wall of described multiple stone bolt, be provided with from top to bottom external screw thread, between each stone bolt and fixed head group all by screw nut and under screw nut and fix.
On the quantity of described stone bolt and every layer of fixed head, the quantity of set bolt hole is just the same.
The steel plate that described upper strata fixed head, middle level fixed head and lower floor's fixed head are 4～10mm by thickness processes.
Positive beneficial effect of the present utility model is as follows:
1, three layers of fixed head size structure of the present utility model are in full accord, all be square structure, on the corner location of every layer of fixed head, be provided with a corner bolt hole, the circle center line connecting in four corner bolt holes forms a little square, be provided with a centre bolt hole in the center of fixed head, on the circle taking fixed head center as the center of circle, be evenly provided with 4 bolts hole, the size of above-mentioned each bolt hole is in full accord, and the diameter that diameter of a circle adds upper bolt hole equals the little foursquare length of side.Design makes the range deviation of single bolt in stone bolt cage be converted into machining deviation, misalignment of axe and the perpendicularity deviation of fixed head group like this, by polyvoltine one, complicated operation is greatly simplified.
2, the utility model utilizes fixed head group to be used as the carrier of multiple stone bolt fixed supports, multiple stone bolt are fixed together and are formed stone bolt cage by upper strata fixed head, middle level fixed head and lower floor's fixed head, the quantity of stone bolt is the same with the quantity of bolt hole, organicly like this form a Novel feet bolt group, not only ensured the precision that bolt is installed but also made installation work convenient and swift.
3, Novel feet bolt group of the present utility model is applicable to the bolt group being made up of multiple bolts, installs and uses scope wide, is specially adapted to the installation of substation truss pre-embedded anchoring bolts, is easy to promote, and has good economic benefit.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view at A-A place in Fig. 1.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to Fig. 1 and Fig. 2, a kind of Novel feet bolt group, comprises multiple stone bolt 4 and fixed head group, and fixed head group is made up of upper strata fixed head 1, middle level fixed head 2 and lower floor's fixed head 3, and three layers of fixed head size structure are in full accord, are all square structure; Be provided with a corner bolt hole 8 at the corner location of every layer of fixed head, one of the circle center line connecting formation in four corner bolt holes 8 is little by square 11, be provided with a centre bolt hole 9 in the center of fixed head, on the circle 10 taking fixed head center as the center of circle, be evenly provided with 4 bolts hole 7, the size of above-mentioned each bolt hole is in full accord, and the diameter that the diameter of circle 10 adds upper bolt hole equals little square 11 the length of side.On the outer wall of described multiple stone bolt 4, be provided with from top to bottom external screw thread, between each stone bolt 4 and fixed head group all by screw nut 5 and under screw nut 6 and fix.Wherein: on the quantity of stone bolt 4 and every layer of fixed head, the quantity of set bolt hole is just the same, the steel plate that upper strata fixed head 1, middle level fixed head 2 and lower floor's fixed head 3 are 4～10mm by thickness processes.
