#太明: 前的现有 ¾术 # 太明: Before the existing ¾ technique

用于连接钢筋混凝土预制桩的施工方法有多种，比如：钢板角钢焊接，硫磺胶泥锱固定，以及机械式接桩法，钢板角钢焊接法，浪费钢材且工效低，硫磺胶泥锚固法又不适用于管桩接驳，而机械式接桩由于需要耗用大量钢材，施工成本较高。本发明的目的 There are many construction methods used to connect reinforced concrete prefabricated piles, such as: steel plate angle steel welding, sulfur cement mortar fixing, and mechanical piling method, steel plate angle steel welding method, waste steel and low work efficiency, sulfur cement anchoring method is not applicable. It is connected to pipe piles, but mechanical piles require a lot of steel, so the construction cost is high. Object of the invention

本发明的目的是为了给出一种结构简单，成本低，且能有效提高施工工效的钢筋混凝土预制桩快速接头。 The object of the present invention is to provide a quick joint of a steel reinforced concrete prefabricated pile which has a simple structure, low cost, and can effectively improve construction efficiency.

本发明的枝术方案 Branching scheme of the present invention

本发明的主要技术方案在于：在桩身的端头上安装有固定箍；固定箍内开有多个连接槽，装在连接槽内的滑块一侧有连接齿，另一侧紧靠被弹簧压着的推杆;，相对接的两个连接槽内的滑块上，连接齿的齿向相反，连接销***连接槽内，其上有两段 έ向相反的啮合齿分别与滑块上的连接齿啮合，使两节桩身相连。 The main technical solution of the present invention is as follows: a fixing hoop is installed on the end of the pile body; a plurality of connecting grooves are opened in the fixing hoop, the slider installed in the connecting groove has connecting teeth on one side, and the other side is close to the A spring-loaded push rod; on the sliders in the two opposite connecting grooves, the teeth of the connecting teeth are opposite, and the connecting pin is inserted into the connecting groove, and there are two segments of oppositely engaging teeth that are opposite to the slider The connecting teeth on the meshing link the two piles together.

在施工时，先将连接销***下节预制桩的连接槽内，然后将上节预制桩的连接槽正对连接销压下，使上、下两节预制桩对接，本发明施工工艺简单，接驳快，每个接头比传统的焊接接头法节约 0 . 1台班，而且由于零件加工也很简单，从总体上大大降低了生产成本。本发明结构牢固，能承受和传递打桩过程中产生的摩擦力和剪切力及由于偏心产生的弯矩。 During construction, the connecting pin is first inserted into the connecting groove of the lower precast pile, and then the connecting groove of the upper precast pile is directly pressed against the connecting pin, so that the upper and lower prefabricated piles are docked. The construction process of the present invention is simple. Faster connection, each joint saves 0.1 shifts compared with the traditional welding joint method, and because the part processing is also simple, the production cost is greatly reduced as a whole. The invention has a firm structure, and can withstand and transmit the frictional force and shearing force generated during the driving process and the bending moment due to eccentricity.

实施例 Examples

如图 1、图 2、图 3所示，本发明的结构是：在上下两节管桩的桩身 1、 1，的端头上安装有固定箍 2、 2 '，固定箍 2、 2 ' 内均匀开设有 8个连接槽 3、 3 '，连接槽数目可根据实际需要适当增减，如图 4所示，装在连接槽 3、 3 ' 内的滑块As shown in FIG. 1, FIG. 2, and FIG. 3, the structure of the present invention is as follows: Fixed ends 2 and 2 'are installed on the ends of the fixed ends. Eight fixed connecting slots 3 and 3' are evenly arranged in the fixed ends 2 and 2 '. The number of connecting slots can be appropriately increased or decreased according to actual needs. Sliders in connection slots 3, 3 '

4、 4，一侧有连接齿 5、 5 '，另一侧紧靠被弹簧 6、 6，压着的推杆 7、 7 ', 相对接的两个连接槽 3、 3，内的滑块 4、 4 ' 上，连接齿 5、 5，的齿向相反，连接销 8***连接槽 3、 3 ' 内，先推动滑块 4、 4 ' 后移，当连接销上的啮合齿4, 4, one side has connecting teeth 5, 5 ', the other side is close to the push rods 7, 7' pressed by springs 6, 6, and two connecting grooves 3, 3, which are opposite to each other, and the slider inside At 4, 4 ', the teeth of the connecting teeth 5, 5 are opposite, the connecting pin 8 is inserted into the connecting grooves 3, 3', and the slider 4, 4 'is pushed first and then moved back. When the engaging teeth on the connecting pin

9、 9，与滑块 4、 4 ' 上的连接齿 5、 5 ' 正对后，弹簧推动推杆 7、 7 '，滑块 4、 4 ' 前移，使啮合齿与连接齿咬合。为与两节桩身内的滑块配合，连接销上的啮合齿 9、 9 ' 的齿向也是相反的。为了提高接头的密封性能，在相啮合的齿间填充有密封胶，这样还可以防止桩在水平方向及竖直方向产生位移。 9, 9, directly opposite the connecting teeth 5, 5 'on the sliders 4, 4', the spring pushes the push rod 7, 7 ', and the sliders 4, 4' move forward to engage the engaging teeth with the connecting teeth. In order to cooperate with the sliders in the two-section pile body, the tooth directions of the engaging teeth 9, 9 'on the connecting pin are also reversed. In order to improve the sealing performance of the joint, a sealant is filled between the meshing teeth, which can also prevent the pile from being displaced in the horizontal and vertical directions.
