The invention discloses an anti-stretching steel support shaft axial pressure device and an axial force stepless adjusting method. The axial pressure device is composed of a bearing conversion key, aloading bin, a jack, variable section connecting keys, an axial force stepless adjusting wedge-shaped key and anti-stretching connecting bolts. One end of the bearing conversion key is connected withthe loading bin, and the other end of the bearing conversion key is connected with the variable section connecting keys. The space for mounting and loading of the jack and a locating seat are left onthe loading bin. The jack is placed in the loading bin, and a loading piston of the jack penetrates through a loading locating hole and directly acts on an end plate of the bearing conversion key. Theaxial force stepless adjusting wedge-shaped key is in a uniform-thickness big-end-up trapezoid shape and is made of a thick steel plate. The front ends of the variable section connecting keys are connected with the loading bin, and the rear ends of the variable section connecting keys can be connected with profile steel of different sections. Connection between the bearing conversion key and theloading bin and connection between the variable section connecting keys and steel supports adopt the anti-stretching connecting bolts to achieve assembling, and tensile force can be resisted. The device has the advantages that force transmission and force maintaining are reliable, the manufacturing cost is reduced, the construction period is shortened, and good economic and social value is achieved.
本发明公开了一种抗拉伸的钢支撑轴向加压装置与轴力无级调节方法，其轴向加压装置是由承载转换键、加载仓、千斤顶、变截面连接键、轴力无级调节楔形键和抗拉连接螺栓组成；承载转换键的一端与加载仓相连，另一端与变截面连接键相连；加载仓留有安装加载千斤顶的空间及定位座；千斤顶安放在加载仓内，千斤顶的加载活塞穿过加载定位孔，直接作用在承载转换键的端板上；轴力无级调节楔形键呈等厚度的上大下小梯形，由厚钢板制成；变截面连接键的前端与加载仓相连，后端能分别与不同截面的型钢相连；承载转换键与加载仓、变截面连接键和钢支撑之间的连接均采用抗拉连接螺栓装配，能抵抗拉力。该装置具有传力和保力可靠，降低造价和缩短工期，具有良好的的经济和社会价值价值。
