The accompanying drawing explanation
Fig. 1 is for to connect into cancellated schematic diagram by connector by each fixed head;
The schematic diagram that Fig. 2 is fixed head and firm banking;
In figure, be labeled as: connector 1, upper end nut 2, double end stone bolt 3, lower end nut 4, firm banking 5, shearing resistance box 6, fixed head 7, bolt of fixing plate installing hole 8, bolt of lower base installing hole 9, protection tube 10.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As depicted in figs. 1 and 2, group of the present invention double end stone bolt integral built-in structure, comprise a plurality of unit that are intervally arranged, each unit comprises firm banking 5, is positioned at fixed head 7 and one group of double end stone bolt 3 of firm banking 5 tops, double end stone bolt 3 is vertical with firm banking 5 and fixed head 7 respectively, the two ends of double end stone bolt 3 are threaded with firm banking 5 and fixed head 7 respectively, the top of double end stone bolt 3 is positioned at the top of fixed head 7, and each fixed head 7 connects into net structure by connector 1.The top of double end stone bolt 3 is positioned at the top of fixed head 7, and namely the upper end threaded portion of double end stone bolt 3 is exposed at the top of fixed head 7 outward, for join dependency structure and equipment.Dual positioning effect by firm banking 5 and fixed head 7, can effectively guarantee that double end stone bolt 3 vertically arranges, arrange vertical with horizontal plane namely, and in casting process, because the Dual positioning effect of firm banking 5 and fixed head 7 can make double end stone bolt 3 be difficult for the occurrence positions skew.Simultaneously, owing to by connector, each fixed head 7 being connected into to net structure, thereby make unit form an integral body.The position of the double end stone bolt 3 arranged on unit is subject to the restriction of other unit, makes the position of each double end stone bolt 3 fix, difficult departing from, thus effectively guaranteed the installation accuracy of double end stone bolt 3.Above-mentioned connector can be steel bar, steel pipe, steel plate etc.
The number of above-mentioned one group of double end stone bolt can be 2,3,4 etc.Can set according to the real needs of equipment.For example the number of one group of double end stone bolt is 2, and 2 double end stone bolt are separately positioned on the two ends of fixed head 7.The two ends that above-mentioned 2 double end stone bolt are separately positioned on fixed head 7 are conducive to make fixed head 7 stressed evenly, not yielding, thereby are conducive to guarantee the installation accuracy of double end stone bolt.
Further, on the basis of the above, be provided with shearing resistance box 6 on fixed head 7.The box body that shearing resistance box 6 is a upper end open, the box body inner hollow, can be made by steel plate.Shearing resistance box 6 is, for convenient, steel column is set within it, and then connects other steel work on steel column.
The connected mode of double end stone bolt 3 and fixed head 7 and firm banking 5 has multiple, and for example double end stone bolt 3 is threaded and is threaded with fixed head 7 by nut with the screwed hole on firm banking 5.But arrange like this, fixing of double end stone bolt 3 is firm not.Be convenient to installation and fixed in order to make double end stone bolt 3, be provided with bolt of fixing plate installing hole 8 on fixed head 7, bolt of fixing plate installing hole 8 is screwed hole, and double end stone bolt 3 is threaded with fixed head 7 by upper end nut 2 and bolt of fixing plate installing hole 8; Be provided with bolt of lower base installing hole 9 on firm banking 5, bolt of lower base installing hole 9 is screwed hole, and double end stone bolt 3 is threaded with firm banking 5 by bolt of lower base installing hole 9 and lower end nut 4.
Above-mentioned unit can need to be arranged according to equipment.It is to be the capable M row of N mode to arrange that general device requires.At this moment, can will be connected with adjacent two fixed heads of a line and same row by connector, as shown in Figure 1, with this, form net structure.
In order to avoid the screw top of double end stone bolt damaged when the concreting, on the basis of the above, the top overcoat of double end stone bolt 3 has protection tube 10.Above-mentioned protection tube 10 can be pvc pipe etc.Protection tube 10 can be protected the screw top of double end stone bolt 3.
Be below the job practices of above-mentioned pre-buried structure:
A, make a plurality of firm bankings 5 and a plurality of fixed head 7, open bolt of lower base installing hole 9 on firm banking 5, bolt of lower base installing hole 9 is screwed hole, open bolt of fixing plate installing hole 8 on fixed head 7, bolt of fixing plate installing hole 8 is screwed hole, wherein, when fixed head 7 is arranged on the top of corresponding firm banking 5, the axial line of assurance bolt of lower base installing hole 9 overlaps with the axial line of corresponding bolt of fixing plate installing hole 8, can guarantee that like this double end stone bolt is vertical with firm banking with fixed head after installing, and then can guarantee that the double end stone bolt is vertical with horizontal plane,
B, by each firm banking 5 location, firm banking 5 can be fixed on pouring pile head, at each bolt of lower base installing hole place, lower end nut 4 is set, the lower end of each double end stone bolt 3 is threaded with corresponding lower end nut 4 and bolt of lower base installing hole 9, protruded length by lower end nut 4 capable of regulating double end stone bolt 3, make it to meet installation code;
C, fixed head 7 is arranged on to the top of corresponding firm banking 5, its top of concrete after highly guaranteeing fixed head 7 end faces and building is concordant, and at bolt of fixing plate installing hole 8 places of fixed head 7, end nut 2 is set, the upper end of each double end stone bolt 3 is threaded with corresponding upper end nut 2 and bolt of fixing plate installing hole 8, the top of double end stone bolt 3 is positioned at the top of fixed head 7, while arranging, can directly the top of double end stone bolt 3 be pressed into and pass the bolt of fixing plate installing hole 8 of fixed head 7, screw thread by each double end stone bolt 3 upper ends and bolt of fixing plate installing hole 8 coordinate to come supporting and location fixed head 7, then lock double end stone bolt 3 by upper end nut 2,
D, by connector 1, each fixed head 7 is connected into to net structure, protected for the screw top to the double end stone bolt, also comprise step e, at the top of each double end stone bolt overcoat protection tube 10.But last concreting forms final foundation structure.
