Hole 20；
During connection installation, connecting bolt 4 sequentially passes through the through hole 20 of first through hole 10 and second, fixes and connects with tensioning nut 5
Connect.
Prestressed concrete member refers to prefabricated tubular pile, precast square pile, prefabricated T-shaped stake etc., sheet material in the technical program
100 be stretch board (as shown in Figure 1) or fixed plate (as shown in Figure 3) or common stake connecting plate in tubular piles stretching mechanism, and it is corresponding
Can rounded or square or T-shaped.
As shown in Figure 10, Figure 11 and Figure 12, the technical scheme is in tensioning, first by board body 1 correspondingly and on steel reinforcement cage
Tensioning nut 5 be connected by connecting bolt 4, then again by tensioning mechanism for implementing tensioning, due in board body 1
Set and correspond the first bulge-structure 2 abutted with tensioning nut 4, the first bulge-structure 2 protrudes from the level of board body 1
End face so that prestressed concrete member is in forming process, end face and the prestressed concrete member shaping of tensioning nut 5
Certain intervals space between end face be present, that is, it is not exposed make it that tensioning nut is lowered into prestressed concrete member, and
Interstitial spaces form a groove 6 between the end face of tensioning nut and the end face of prestressed concrete member shaping, on the one hand, tensioning
Nut 5 is sunk down into prestressed concrete member, contact of the component in docking operation between nut can be effectively avoided, so as to prevent
Injury of the component in docking operation or in work progress to nut or component in itself, on the other hand, the groove 6 of formation can be with
One accommodating cavity is provided, convenient storage is can be used for when component docks and accommodates the chemical agents such as epoxy resin, plays preservative efficacy.
It is various as the specific constructive form of the first bulge-structure 2, the present invention according to actual production and condition of construction enumerate as
Lower three kinds more preferred embodiments：
" embodiment 1 "
As shown in Fig. 5, Fig. 6 and Fig. 7, the first bulge-structure 2 is directly integrally formed on the end face of board body 1, its bottom
End face 21 is connected with the end face of board body 1, and stretches out along the end face of board body 1 and convex to form and tensioning nut 5
The top end face 22 that abuts against of end face.
More specifically, the end face of the bottom face 21 of the first bulge-structure 2 and board body 1 can use and be welded to connect.
In addition, the first bulge-structure 2 can also be with the integral formation type structure of board body 1, i.e., the first bulge-structure 2 can
To be that board body 1 is formed out by turning or milling mode in board body 1.
" embodiment 2 "
The first bulge-structure 2 in above-described embodiment 1 deposits the problem of non-exchange upon wear.In addition, ledge needs
Want wear-resistant, it is necessary to through Overheating Treatment, program inconvenience local heat treatmet, particularly, when the first bulge-structure 2 and sheet material sheet
During the integral formation type structure of body 1, difficulty of processing is very big if reprocessing after the bulk heat treatmet, can if being heat-treated again after the processing
Only 3~5mm of surface occur thermal effectiveness, it is impossible to meets requirement.
Therefore, as shown in figure 8, the first bulge-structure 2 includes setting the second through hole 20, first through hole in bushing 23, bushing 23
The edge seat 24 corresponding with bushing 23 is set in 10, bushing 23 corresponding inlay are fixedly connected in edge seat 24, and bushing 23 top
Extend outwardly and protrude from the end face of board body 1.
Bushing 23 are interference fitted with edge seat 24 in the technical scheme, and bushing 23 are inlayed in seat 24 using press mode insertion, compared with
Above-described embodiment 1, board body 1 (such as stretch board, fixed plate) can use the steel of regular tenacity, and only need bushing 23 to adopt
With the steel Jing Guo heat treatment process, cost can be substantially reduced, replacing can also be knocked out after bushing 23 abrasions.Certainly, exist
Board body 1 and bushing 23 can be that steel can also be that other materials is made in this scheme.Moreover, bushing 23 and edge seat
24 connected mode can also be by the way of threaded connection.
" embodiment 3 "
As shown in figure 9, the present embodiment and the structure of above-described embodiment 2 and principle are substantially similar, its difference is：Bushing 23
End face of the top end face along board body 1 horizontally outward extends to form an abutting part 25 for being suitable to abut against with the end face of board body 1,
The other end of abutting part 25 is corresponding with the end face of tensioning nut 5 to abut.
In addition it is also necessary to, it is noted that the first bulge-structure 2 protrudes from the end face of board body 1 in the above-mentioned technical solutions
At least 1mm.
In addition, the second outstanding bulge-structure 3 is additionally provided with the centre of board body 1, second is raised
The bulge-structure 2 of structure 3 and first is located at the same side of board body 1.
The effect of second bulge-structure 3 is the intensity for improving stretch board and fixed plate, while in centrifugation, mud can stay in
In the groove that bulge-structure is formed, avoid mud from being flowed out from the slit of stretch board and fixed plate, influence the cleaning in overall workshop.
Certainly, it the above is only the concrete application example of the present invention, protection scope of the present invention be not limited in any way.It is all
The technical scheme formed using equivalent transformation or equivalent replacement, all fall within rights protection scope of the present invention.
