Frame beam strength detection device for constructional engineering

The frame beam strength detection device comprises a connecting base, four polished rods are fixedly arranged on one side of the connecting base at equal intervals, pressing pieces are fixedly arranged at one ends of the four polished rods, the edges of one sides of the pressing pieces are fixedly connected with one ends of the four polished rods respectively, an installation opening is formed in the middle of each pressing piece, and the other ends of the four polished rods are fixedly connected with the installation opening. The outer walls of the four polished rods are sleeved with moving seats, the edges of the moving seats are connected with the outer walls of the four polished rods in a penetrating and inserting mode, the outer walls of two of the polished rods are sleeved with springs, one ends of the two springs abut against one sides of the moving seats, and the other ends of the two springs abut against one sides of the pressing pieces. During detection, the pressing sheet is attached to and abuts a
