It is conducive to the development of my country's building industrialization, improving production efficiency and saving energy, developing green and environmentally friendly buildings, and is conducive to improving and ensuring the quality of construction projects. Compared with the cast-in-place construction method, the prefabricated RC structure is conducive to green construction, because the prefabricated construction can better meet the requirements of green construction, such as land saving, energy saving, material saving, water saving and environmental protection, and reduce the negative impact on the environment.

利用空压效应的孔内销件移动的装置主体由预留孔、销孔和销件组成，其中第一销孔1与第二销孔2之间的轴线在同一直线上，第一销孔1的长度为2.5L，第二销孔2的长度为L，第一销孔1和第二销孔2为水平孔道；竖向孔道由第一预留孔（进气孔）3、第一预留孔（排气孔、泌水孔）4、第二预留孔（注浆孔、排气孔）5共三部分组成，竖向孔道与水平向孔道相垂直并贯通。剪力销由钢棒6、定位钢筋7以及密封橡胶圈8三部分组成，其长度为2L。钢棒6的长度要小于第一销孔的长度，以保证剪力销可以全部装入第一销孔中，方便预制构件的安装，保证剪力销在安装过程中，不被碰撞。密封橡胶圈8起到增加空气阻力，以保证销件6被高压空气推动。定位钢筋7的主要作用有两个，其一，在第一销孔和第二销孔之间有错台时，剪力销端部不会发生阻挡；其二，保证剪力销可以被水泥砂浆充分包裹，增加剪力销与预制构件间的整体性。The main body of the device that uses the air pressure effect to move the pin in the hole is composed of a reserved hole, a pin hole and a pin, wherein the axes between the first pin hole 1 and the second pin hole 2 are on the same straight line, and the first pin hole 1 The length of the second pin hole 2 is L, the first pin hole 1 and the second pin hole 2 are horizontal channels; the vertical channel is composed of the first reserved hole (air intake hole) 3, the first reserved hole The reserved hole (vent hole, bleeding hole) 4 and the second reserved hole (grouting hole, vent hole) 5 are composed of three parts, and the vertical channel is perpendicular to the horizontal channel and runs through it. The shear pin is composed of steel rod 6, positioning steel bar 7 and sealing rubber ring 8, and its length is 2L. The length of steel bar 6 will be less than the length of the first pin hole, to ensure that the shear pins can all be packed into the first pin holes, to facilitate the installation of prefabricated components, to ensure that the shear pins are not collided during installation. The sealing rubber ring 8 plays the role of increasing air resistance to ensure that the pin 6 is pushed by high-pressure air. The main function of positioning reinforcement 7 is two, one, when there is a staggered platform between the first pin hole and the second pin hole, the end of the shear pin will not be blocked; the other is to ensure that the shear pin can be cemented The mortar is fully wrapped to increase the integrity between the shear pin and the prefabricated components.
一种利用空压效应的孔内销件移动的装置的制作和使用方法，包括如下操作步骤，A method for making and using a device for moving a pin in a hole using the air pressure effect, comprising the following steps,
（1）制备剪力销，剪力销的主体部分为钢棒6，长度为2L，在钢棒的端部安装有密封橡胶圈8，在钢棒的中部焊接有定位钢筋7，定位钢筋7由三根较细钢筋组成，呈120°夹角布置；(1) Prepare the shear pin. The main part of the shear pin is a steel rod 6 with a length of 2L.
