Abstract
The invention relates to a method for fastening a tensioning nut for a concrete tubular pile. The method comprises the following steps: 1) sleeving an annular soft belt on the inner side of a tensioning machine in advance, and exposing one end on the outer side; 2) after the tensioning machine stops, sleeving the tensioning nut with the annular soft belt; 3) pulling the annular soft belt and fastening the tensioning nut. Furthermore, the annular soft belt is a triangular belt. According to the method provided by the invention, the operation is simple, the safety is effectively ensured, and the efficiency is greatly increased.
Description
[technical field]
The present invention relates to a kind of concrete tubular pile production technical field of building trade, be specifically related to a kind of method of concrete tubular pile locking tensioning nut.
[background technology]
China prestressed concrete pipe pile manufacturer has reached 700, and annual production breaks through more than 400,000,000 meters, is to produce in the world and apply the country that prestressed concrete pipe pile is maximum.Produce prestressed concrete pipe pile and have critical process one: prestressed stretch-draw.Every pile tube must, through stretch-draw, be used nut check stretching force by rod iron with 70% left and right that stretching machine is stretched to its standard tensile strength after pouring into material again.
Mostly be at present that by following two kinds of methods, locking a spiral shell draws mother.(1) employee stretches into the direct nutting of hand from the direct handle of outside peep hole.Due to stretching process occasional, occur the problems such as disconnected muscle, equipment fault, the as easy as rolling off a log operative employee of causing points and palm industrial accident.This kind of mode do not ensure safely.(2) with 1 large spanner, look for different angles to put in stubborn tensioning nut, can only twist 1/4 of 1 circle silk bud at every turn, will twist altogether 20 circle silk buds, too slow, waste production time, efficiency is low, hinders in process of production whole piece streamline speed, the very fast rising of cost.
In view of this, the inventor, for the defect further investigation of prior art, has this case to produce then.
[summary of the invention]
Technical problem to be solved by this invention is to provide a kind of method of the simple locking of concrete tubular pile efficiently tensioning nut.
The present invention is achieved in that
The method of concrete tubular pile locking tensioning nut, comprises the steps:
Step 1: in advance a soft band of annular is enclosed within to stretching machine inner side, one end is exposed;
Step 2: machine to be tensioned is quiet stop after, with annular soft band, entangle tensioning nut;
Step 3: pull tensioning nut described in annular soft locking.
Further, the soft band of described annular is V-belt.
The invention has the advantages that: the present invention is simple to operate, safety obtains powerful guarantee, and efficiency promotes greatly.
[accompanying drawing explanation]
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
[specific embodiment]
As shown in Figure 1, the method for concrete tubular pile locking tensioning nut, comprises the steps:
Step 1: be with 1 to be enclosed within stretching machine 2 inner sides by annular is soft in advance, one end is exposed;
Step 2: after quiet the stopping of machine 2 to be tensioned, be with 1 to entangle tensioning nut 3 with annular is soft;
Step 3: pull the soft described tensioning nut 3 of 1 locking of being with of annular.
Wherein, annular soft band is V-belt.
The present invention is simple to operate, and safety obtains powerful guarantee, and efficiency promotes greatly.
The foregoing is only better enforcement use-case of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
Claims (2)
1. the method for concrete tubular pile locking tensioning nut, is characterized in that: comprise the steps:
Step 1: in advance a soft band of annular is enclosed within to stretching machine inner side, one end is exposed;
Step 2: machine to be tensioned is quiet stop after, with annular soft band, entangle tensioning nut;
Step 3: pull tensioning nut described in annular soft locking.
2. the method for concrete tubular pile locking tensioning nut as claimed in claim 1, is characterized in that: the soft band of described annular is V-belt.
