摘要： The slab module disclosed herein consists of a precast prestressed slab section which may have solid or a hollow core. The slab module has a longitudinal male inserting edge which when installed mates with a complimentary-shaped female receiving edge on a similar slab module. However, the dimensions of the female edge are slightly greater than the corresponding male edges. The bottom surface of both male and female members are inclined at an angle to the plane of a side of the slab module so that the inserted module will move upward in translation as well as move toward the module into which its edge is being inserted. When the top or bottom surface (as desired) of the inserting module is at the same plane as the corresponding surface of the inserted module, a positioning spacer may be inserted to limit further movement and to maintain the relative position of the modules. The spacers may be in the form of plates which will vary in thickness. The joints between slab modules will be grouted after the slab modules are assembled. The modules will be drawn together by tendons. After assembly and adjustment of the slab modules, the tendons are post-tensioned and permanently anchored. The finished deck will appear and function as a smooth, continuous slab.

摘要翻译： 本文公开的板坯模块由可以具有固体或中空芯的预制预应力板段组成。 板模块具有纵向插入插入边缘，当安装在相似的板模块上与互补形状的母接收边缘配合时。 然而，母边缘的尺寸略大于相应的凸缘。 两个阳构件和阴构件的底表面与板模块的一侧的平面成一定角度倾斜，使得插入的模块将以平移方式向上移动，并朝向其边缘被插入其中的模块移动。 当插入模块的顶部或底部表面（根据需要）处于与插入的模块的相应表面相同的平面时，可以插入定位间隔件以限制进一步的移动并保持模块的相对位置。 间隔件可以是厚度变化的板的形式。 在组装板模块后，板模块之间的接缝将被灌浆。 模块将由肌腱一起绘制。 在组装和调整板坯模块后，钢筋后张紧并永久锚定。 完成的甲板将出现并作为一个光滑连续的板坯。
