Abstract
The utility model relates to a groove type fast connecting joint for tubular piles, solving the defects that the welding and cooling time is long and the welding quality is easily influenced by the human factors and weather conditions when the electric welding is used for welding the connecting joint for tubular piles. The utility model provides a groove type fast connecting joint for tubular piles, which is visual, fast, simple, safe, economic, electric welding and pollution free. The utility model is composed of two circular joint components with grooves. One end or two of the two circular joint components is provided with fixation connecting devices. The utility model has fast pile extension speed and is not influenced by human factors and weather conditions. The groove connecting joint does not require the workers with high skill level, the ordinary worker can operate after inspecting and practicing and the standard is easy to obtain. The utility model has no naked light operation, so the construction can be carried out on windy or rainy day. The construction quality is stable and reliable, and the anticorrosion property and the durability are good. The metal parts on the connecting joint are all processed with hot galvanizing. The galvanizing coat is thick. Therefore, the device can be used for a long time, in the bad environment and synthetic effectiveness is good.
Description
(1) technical field:
The utility model relates to a kind of pile tube plough groove type fast connecting joint.
(2) background technology:
Advantages such as prestressed concrete pipe pile has the bearing capacity of single pile height, speed of application is fast, price is suitable, static pressure construction compliance with environmental protection requirements are applied in the construction work more and more widely.But pipe pile joint all adopts electric welding to connect at present, and joints made by electric welding has welding and cool time is long, welding quality is subjected to human factor and weather condition to influence defectives such as big.
(3) utility model content:
The utility model solved existing pipe pile joint all need to adopt electric welding joint could be connected and exist welding and cool time long, welding quality is subjected to artificial factor and weather condition to influence big defective, a kind of directly perceived, quick, simple and easy, safety, economy is provided, exempts from the pile tube plough groove type fast connecting joint of electric welding.
The technical solution of the utility model is as follows: it is that ring joint member by two with grooves constitutes, and is provided with interconnective fixed connection apparatus in the one or both ends of two ring joint members.
The pile tube plough groove type fast connecting joint of the utility model structure: changed the technical matters of existing pipe pile joint, compared, had the following advantages with the technical matters of existing pipe pile joint:
(1) pile extension is quick.Calculate with each joint engineering time, adopt the arc welding welding to need 30 minutes approximately, adopt carbon dioxide gas arc welding to need 15 minutes approximately, and adopt plough groove type snap joint only to need 2 minutes.
(2) get rid of the influence of human factor and weather condition.The ditch trough connection is less demanding to workman's technical level, and general workman can operate after observing practice, and accomplish easily qualified.This technology there is not the naked light operation, still can construct under the blowing and raining condition, and construction quality is reliable and stable.
(3) antiseptic property and good endurance.The joint metal parts is all handled through galvanizing, and zinc coat is thicker, can be in the medium-term and long-term use of adverse circumstances.
(4) comprehensive benefit is good.
Compare with similar achievement:
(4.1) compare with engagement type (machinery) snap joint (this achievement is classified as populariztion of scientific and technical result project in 2002 by the development of the cladding lapicide's journey of Guangzhou silk cotton Co., Ltd by nation-building portion), have more convenient operation, the advantage that cost is lower.The market price of engagement type joint connector improves 10 yuan/m than original, thereby since two thousand two, this achievement is difficult to promote.The market price of plough groove type joint only improves 2.5 yuan/m than former joint.Market prospects are wide.
(4.2) with the authorization notification number: 2536650 pile tube machinery (being threaded) is connected to be compared, and also has more convenient operation, the advantage that cost is lower.This joint estimated cost is 7.5 yuan/m, does not also begin at present to promote.
The utility model has been removed welding procedure from, has improved the reliability that pile tube connects.
