Abstract
The invention relates to a prestressed concrete tubular pile end plate which is particularly suitable for being used as an end plate mated with a PHC (Prestress High Concrete) tubular pile and a PC (Prestressed Concrete) tubular pile. The prestressed concrete tubular pile end plate is characterized by comprising an end plate, wherein an end plate inner bore is arranged in the middle part of the end plate, a plurality of main reinforcement anchor holes are arranged in the end plate, the main reinforcement anchor holes and reinforcement holes are combined together, and reinforcing bulges are arranged at the lower parts of the main reinforcement anchor holes and the reinforcement holes. Each main reinforcement anchor hole is provided with a stepped hole at the upper part and a screwed hole at the lower part; and each reinforcement hole is provided with a countersunk head hole at the upper part and a through hole at the lower part. Since the reinforcing bulges are arranged at the lower parts of the main reinforcement anchor holes and the reinforcement holes, the tensile strength of the prestressed concrete tubular pile end plate can be increased, the thickness of the prestressed concrete tubular pile end plate can be reduced, the amount of steel used in the tubular pile end plate can be lowered, labor intensity of production workers can be reduced, production efficiency can be increased, and production cost is decreased.
Description
Technical field
What the present invention relates to is a kind of prestressed concrete pipe pile end plate, is specially adapted to PHC pile tube, PC pile tube and makes supporting end plate and use.
Background technology
The prestressed concrete pipe pile end plate does not reach tensile strength in the prestressed stretch-draw process at present, necessary upset end plate thickness, meet the design needs, thereby increase cost of production because the increase of end plate thickness causes increasing steel weight, it is low to increase direct labor's labour intensity production efficiency.
Summary of the invention
The present invention seeks to provides a kind of prestressed concrete pipe pile end plate at above-mentioned weak point, the concrete pipe pile end plate is provided with several main muscle anchor holes, reinforced hole, be provided with the reinforcement projection at main muscle anchor hole and reinforced hole bottom, can increase prestressed concrete pipe pile end plate tensile strength, pile end board in condition of equivalent thickness can increase tensile strength greatly, therefore, can reduce pile end board thickness, reduce the pile end board rolled steel dosage, alleviate direct labor's labour intensity, enhance productivity, lower cost of production.
The prestressed concrete pipe pile end plate takes following technical scheme to realize:
The prestressed concrete pipe pile end plate has end plate, is provided with the end plate endoporus at the end plate middle part, and end plate is provided with several main muscle anchor hole and reinforced holes, and main muscle anchor hole and reinforced hole are combined, and is provided with the reinforcement projection at main muscle anchor hole and reinforced hole bottom.
Described main muscle anchor hole top is provided with stepped hole, and the bottom is provided with screwed hole, is used for installing rising drawing bolt.
Described reinforced hole top is provided with counter sink, and the bottom is provided with through hole, is used for the prestressed reinforcing bar.
Operating principle:
When the prestressed concrete pipe pile end plate uses, the prestressed concrete pipe pile end plate is installed in to rise draws the bolt two ends, simultaneously prestressed reinforcement is installed rivet clasp on pile end board, rise and draw bolt to be installed in the main muscle anchor hole, draw by rising and to reach the pile tube design strength, adopt the centrifugal casting concrete again, make prestressed concrete pipe pile by maintenance.
The prestressed concrete pipe pile end plate is reasonable in design, because the concrete pipe pile end plate is provided with several main muscle anchor holes, reinforced hole, be provided with in main muscle anchor hole and reinforced hole bottom and strengthen projection, can increase prestressed concrete pipe pile end plate tensile strength, can increase tensile strength greatly at the pile end board of condition of equivalent thickness, therefore, can reduce pile end board thickness, reduce the pile end board rolled steel dosage, alleviate direct labor's labour intensity, enhance productivity, lower cost of production.
Description of drawings
The invention will be further described below with reference to accompanying drawing:
Fig. 1 is a prestressed concrete pipe pile end plate front view.
Fig. 2 is the prestressed concrete pipe pile end plate B-B sectional view of Fig. 1.
Fig. 3 is the main muscle anchor hole and the reinforced hole enlarged drawing of prestressed concrete pipe pile end plate.
Fig. 4 is the main muscle anchor hole and the reinforced hole A-A sectional view of Fig. 3 prestressed concrete pipe pile end plate.
The specific embodiment
With reference to accompanying drawing 1～4, the prestressed concrete pipe pile end plate has end plate 1, be provided with end plate endoporus 4 at end plate 1 middle part, end plate 1 is provided with several main muscle anchor hole 2 and reinforced holes 3, main muscle anchor hole 2 and reinforced hole 3 are combined, and are provided with reinforcement projection 5 at main muscle anchor hole 2 and reinforced hole 3 bottoms.
Described main muscle anchor hole 2 tops are provided with stepped hole 6, and the bottom is provided with screwed hole 7, are used for installing rising drawing bolt.
Described reinforced hole 3 tops are provided with counter sink 8, and the bottom is provided with through hole 9, is used for the prestressed reinforcing bar.
