Abstract
The utility model provides a concrete tubular pile extension device which comprises a sleeve, wherein the sleeve is composed of a left steel plate and a right steel plate; both the left steel plate and the right steel plate are semi-cylindrical, and the inner diameters of the left steel plate and the right steel plate are the same as the outer diameter of a tubular pile; two stiffening plates are arranged at the edges of the two sides of the left steel plate and the right steel plate respectively; the stiffening plates are welded with the left steel plate and the right steel plate; the edge extension line of each of the stiffening plates penetrates through the axes of each of the semi-cylinders; a plurality of through holes are formed in each of the stiffening plates; fixed bolts are arranged in the through holes; lock sleeves are respectively arranged at the top and the bottom of the sleeve; the lock sleeves are cylindrical; the inner diameter of each of the lock sleeves is the same as the outer diameter of the sleeve. The concrete tubular pile extension device has the following benefits: with adoption of the concrete tubular pile extension device for pile extension, the tubular pile connector is firm, and the bending resistance is high; in addition, the pile extension technology is simple, the device is easy to operate, the pile extension is not affected by the weather and human factors, and the device is high in pile extension speed, and high in efficiency.
Description
Technical field
The utility model belongs to pile tube production labor dress field, especially relates to a kind of pile extension device for concrete pipe pile.
Background technology
Prestressed concrete pipe pile, due to advantages such as bearing capacity of single pile is high, speed of application fast, low prices, is widely used.At present, most engineerings are traditional artificial weldings pipe pile joint being processed to what adopt, technique and qualitatively the method require the symmetrical spot welding 4-6 point of elder generation, when carrying out symmetrical welding, after weld seam is naturally cooling, could continue injection or piling.Because the pile extension technology consumption time of traditional welding is too much, weldquality is subject to the impact of human factor and weather condition, be difficult to guarantee, and be efficiency and the quality that improves pile extension, the pile extension method of seeking other seems particularly necessary.
Utility model content
The purpose of this utility model is to provide a kind of pile extension device for concrete pipe pile, is especially applicable to prestressed concrete pipe pile joint.
The technical solution of the utility model is: a kind of pile extension device for concrete pipe pile, comprise the sleeve that left plate and right steel plate form, described left plate is that half round post and its internal diameter are identical with pile tube external diameter with right steel plate, the both sides of the edge of described left plate and right steel plate are respectively arranged with two stiffeners, described stiffener and left plate and right Plate Welding, the edge extended line of described any stiffener is all by the axle center of semicolumn, on described stiffener, be provided with some through holes, on described through hole, be provided with set bolt, top and the bottom of described sleeve are respectively arranged with lock tube, described lock tube is cylindrical, the internal diameter of described lock tube is identical with the external diameter of sleeve.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, the pile tube up and down that need are connected inserts sleeve, with bolt, be tightened, and the further reinforcing of cover that locks, pile tube interface is firm, anti-bending strength is strong, and pile extension technology is simple, easy operating, is not subject to the impact of weather and human factor, pile extension speed is fast, and efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1, left plate 2, right steel plate 3, sleeve
4, stiffener 5, through hole 6, set bolt
7, lock tube
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of pile extension device for concrete pipe pile of the utility model, comprise the sleeve 3 that left plate 1 and right steel plate 2 form, described left plate 1 is that half round post and its internal diameter are identical with pile tube external diameter with right steel plate 2, the both sides of the edge of described left plate 1 and right steel plate 2 are respectively arranged with two stiffeners 4, described stiffener 4 and left plate 1 and 2 welding of right steel plate, the edge extended line of described any stiffener 4 is all by the axle center of semicolumn, on described stiffener 4, be provided with some through holes 5, on described through hole 5, be provided with set bolt 6, the top of described sleeve 3 and bottom are respectively arranged with lock tube 7, described lock tube 7 is cylindrical, the internal diameter of described lock tube 7 is identical with the external diameter of sleeve 3.
The course of work of this example: the sleeve 3 that left plate 1 is formed with right steel plate 2 is enclosed within respectively top and the bottom of two root canal piles that need be connected, with set bolt 6, pass through hole 5 fixed muffles 3, then lock tube 7 is passed respectively to top and the bottom of sleeve 3, further reinforce, thereby two root canal piles are linked together securely.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
