As shown in fig. 1-2, a precast beam splicing template comprises a square installation frame 1, wherein a transverse through groove is formed in the top wall of the installation frame 1, and a transverse chute 11 is fixed on the bottom wall; the device also comprises a left transverse moving part arranged in the mounting frame 1; the left lateral movement part comprises a transverse air cylinder 3 fixed on the outer side wall of the mounting frame 1, and a piston rod 31 of the transverse air cylinder 3 penetrates through the side wall of the mounting frame 1 and is connected with the vertical connecting arm 2 at the tail end through a connecting sleeve 32; the bottom of the connecting arm 2 is provided with a sliding block 22 matched with the transverse chute 11, the top of the connecting arm exceeds the upper surface of the transverse chute, and a connecting seat 21 is fixed at the tail end of the connecting arm; the device also comprises a right transverse moving part which is arranged in the mounting frame 1 and is symmetrical with the left transverse moving part in structure;
the lifting nut seat is characterized by further comprising a portal frame 4 fixed on the connecting seat 21, wherein a lifting through groove 41 is formed in the top wall of the portal frame 4, and a lifting nut seat 42 is further fixed at the lifting through groove 41 of the portal frame 4; the device further comprises a movable screw rod 43 vertically screwed into the lifting nut seat 42 and inserted into the portal frame 4, a hand wheel 44 is arranged at the top of the movable screw rod 43, and a horizontal anti-slip clamping block 45 is arranged at the bottom of the movable screw rod through a rotating bearing.
In the utility model, the main working principle is as follows: firstly, the movable screw 43 is rotated by the hand wheel 44 at the top of the movable screw 43, so that the movable screw 43 descends in the lifting nut seat 42 and the lifting through groove 41, and then drives the anti-slip clamping blocks 45 to move downwards together, the precast beam is placed in the portal frame 4, the direction of the anti-slip clamping blocks 45 is adjusted to enable the precast beam to be abutted against along with the descending of the movable screw 43, and the purpose of rapidly clamping and fixing the precast beam is achieved. Then, the transverse air cylinder 3 is started, the piston rod 31 of the transverse air cylinder 3 extends towards the inside of the mounting frame 1, and accordingly the connecting arm 2 is driven by the connecting sleeve 32 to move transversely in the transverse sliding groove 11 under the action of the sliding block 22, so that the connecting arms 2 on the left side and the right side move towards each other to approach each other, and then the prefabricated beams which are fixed by the portal frame 4, the movable screw 43 and the anti-slip clamping blocks 45 are driven to approach each other synchronously on the upper connecting seat 21, and rapid splicing is achieved.
