Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 2-5, the utility model discloses a precast concrete component body 1 all reserves on two connection faces of the left and right sides of precast concrete component body 1 and pours spread groove 2, pours spread groove 2 and sets up along precast concrete component body 1's extending direction, all sets up one at least standing groove 3 in every is pour spread groove 2, standing groove 3 available cutting machine cutting shaping, standing groove 3 sets up along the extending direction of pouring spread groove 2. A water stopping sheet 4 is placed in each placing groove 3, one part of the water stopping sheet 4 is inserted into the placing groove 3, and the other part of the water stopping sheet 4 is exposed in the pouring connecting groove 2. The water stop sheet 4 is connected with the placing groove 3 through structural adhesive.
