forced concrete structure reinforced with an overviewRein
Since the reform and opening up, with the national economy's rapid and sustained development of a reinforced concrete structure built, reinforced with the development of technology has been great。 Therefore, to promote the u of advanced technology 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 are 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 ud reinforcement linking method primarily applicable to the construction site。 Ways has its own characteristics and different application, and in the continuous development and improvement。 In actual production, should be bad 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
1。1 radial squeeze link
Will be a steel sleeve in two ts 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 cloly integrated with reinforced through reinforced steel sleeve and Wang Liang's 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, construction 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 校长英文Ⅱ , Ⅲ , Ⅳ grade reinforcing bar (including welding ba
d reinforcing bar ) with ribbing of Ф 18— 50mm, connection between the same diameter or different diameters reinforcing bar .
1.2 must squeeze link
study mathExtruders ud in the covers, reinforced axis along the cold metal sleeve squeeze dedicated to inrt sleeve Lane two hot rolling steel drums into a highly integrated mechanical linking methods.
Characteristic: Easy to operate and joining fast and not having flame homework , can construct for 24 hours , save a large number of reinforcing bars and energy.
Applicable scope : Suitable for , t up according to first and cond class antidetonation requirement —proof armored concrete structure ФⅡ , Ⅲ grade reinforcing bar with ribbing of hot rolling of 20- 32mm join and construct live.
1.3 cone thread connectingsanta is coming to town
Using cone thread to bear pulled, presd both effort and lf—locking nature, undergo good principles will be reinforced by linking into cone—processing thread at the moment the value of integration into the joints connecting 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.
成都英语翻译Applicable scope : Suitable for the concrete structure of the industry , civil building and general structures, reinforcing bar diameter is for Фfor the the 16- 40mm one Ⅱ , Ⅲ grade verticality, it is the oblique to or reinforcing bars horizontal join construct live.
conclusions
The are now commonly ud to connect steel synthesis methods, which links technology in the United States, Britain, Japan and other countries are widely ud。 There are different ways to connect their different characteristics and scope of the actual
construction of production depending on the specific project choo a suitable method of connecting to achieve both energy conrvation and saving time limit for a project ends。
钢筋混凝土结构中钢筋连接综述
改革开放以来,随着国民经济的快速、持久发展,各种钢筋混凝土建筑结构大量建造,钢筋连接技术得到很大的发展.因此,推广应用先进的钢筋连接技术,对于提高工程质量、加快施工速度、提高劳动生产率、降低成本,具有十分重要的意义.
钢筋连接技术可分为钢筋焊接和钢筋机械连接两大类.钢筋焊接有6种焊接方法,有的适用于预制厂,有的适用于现场施工,有的两者都适用。钢筋机械连接常用有3种方法,主要适用于现场施工。各种方法有其自身特点和不同的适用范围,并在不断发展和改进。在实际生产中,应根据具体的工作条件、工作环境和技术要求,选用合适的方法以期达到最佳的综合效益。
1、钢筋机械连接
1.1 径向挤压连接
将一个钢套筒套在两根带肋钢筋的端部,用超高压液压设备(挤压钳)沿钢套筒径向挤压钢套管,在挤压钳挤压力作用下,钢套筒产生塑性变形与钢筋紧密结合,通过钢套筒与钢筋横肋的咬合,将两根钢筋牢固连接在一起。
特点:接头强度高,性能可靠,能够承受高应力反复拉压载荷及疲劳载荷。
操作简便、施工速度快、节约能源和材料、综合经济效益好,该方法已在工程中大量应用。
适用范围:适用于Ф18~50mm的Ⅱ论文网站大全、Ⅲ、Ⅳ级带肋钢筋(包括焊接性差的钢筋),相同直径或不同直径钢筋之间的连接。
1.2 轴向挤压连接ginger
将两钢筋安放成对接形式,利用焊接电流通过两钢筋接触点产生塑性区及均匀的液体金属层,迅速施加顶锻力完成的一种压焊方法。
特点:操作简单、速度快、无明火作业、可全天候施工,节约大量钢筋和能源.
2020高考试题
适用范围:适用于按一、二级抗震设防要求的钢筋混凝土结构中Ф20~32mm的Ⅱ、Ⅲ级热轧带肋钢筋现场连接施工.
文化常识1.3gelang 锥螺纹连接
利用锥螺纹能承受拉、压两种作用力及自锁性、密封性好的原理,将钢筋的连接端加工成锥螺纹,按规定的力矩值把钢筋连接成一体的接头.
