1、 forced concrete structure reinforced with an overviewRein Since the reform and opening up, with the national economys rapid and sustained development of a reinforced concrete structure built, reinforced with the development of technology has been great. Therefore, to promote the use of advanced tec
2、hnology reinforced connecting to improve project quality and speed up the pace of construction, improve labor productivity, reduce costs, and is of great significance. Reinforced steel bars connecting technologies can be divided into two broad categories linking welding machinery and steel. There ar
3、e six types of welding steel welding methods, and some apply to the prefabricated plant, and some apply to the construction site, some of both apply. There are three types of machinery commonly used reinforcement linking method primarily applicable to the construction site. Ways has its own characte
4、ristics and different application, and in the continuous development and improvement. In actual production, should be based on specific conditions of work, working environment and technical requirements, the choice of suitable methods to achieve the best overall efficiency. 1、 steel mechanical link
5、1.1 radial squeeze link Will be a steel sleeve in two sets to the highly-reinforced Department with superhigh pressure hydraulic equipment (squeeze tongs) along steel sleeve radial squeeze steel casing, in squeezing out tongs squeeze pressure role of a steel sleeve plasticity deformation closely int
6、egrated with reinforced through reinforced steel sleeve and Wang Liangs Position will be two solid steel bars linked Characteristic: Connect intensity to be high, performance reliable, can bear high stress draw and pigeonhole the load and tired load repeatedly. Easy and simple to handle, constructio
7、n fast, save energy and material, comprehensive economy profitable, this method has been already a large amount of application in the project. Applicable scope : Suitable for , , grade reinforcing bar (including welding bad reinforcing bar ) with ribbing of 18- 50mm, connection between the same diam
8、eter or different diameters reinforcing bar . 1.2 must squeeze link Extruders used in the covers, reinforced axis along the cold metal sleeve squeeze dedicated to insert sleeve Lane two hot rolling steel drums into a highly integrated mechanical linking methods. Characteristic: Easy to operate and j
9、oining fast and not having flame homework , can construct for 24 hours , save a large number of reinforcing bars and energy. Applicable scope : Suitable for , set up according to first and second class antidetonation requirement -proof armored concrete structure , grade reinforcing bar with ribbing
10、of hot rolling of 20- 32mm join and construct live. 1.3 cone thread connecting Using cone thread to bear pulled, pressed both effort and self-locking nature, undergo good principles will be reinforced by linking into cone-processing thread at the moment the value of integration into the joints conne
11、cting steel bars. Characteristic: Simple , all right preparatory cut of the craft , connecting fast, concentricity is good, have pattern person who restrain from advantage reinforcing bar carbon content. Applicable scope : Suitable for the concrete structure of the industry , civil building and gene
12、ral structures, reinforcing bar diameter is for for the the 16- 40mm one , grade verticality, it is the oblique to or reinforcing bars horizontal join construct live. conclusions These are now commonly used to connect steel synthesis methods, which links technology in the United States, Britain, Jap
13、an and other countries are widely used. There are different ways to connect their different characteristics and scope of the actual construction of production depending on the specific project choose a suitable method of connecting to achieve both energy conservation and saving time limit for a project ends.
