Beam clamping device for building

The utility model relates to a beam clamping device for a building, which comprises a beam clamp and a beam clamping device, the two U-shaped rods are connected with the connecting positions on the bottom plate through the ends, in the U-shaped opening direction, of the U-shaped rods correspondingly, the connected U-shaped rods are erected on the bottom plate, the height of the U-shaped rods relative to the bottom plate can be adjusted, and the two U-shaped rods and the bottom plate jointly form a clamping area for clamping a building beam, so that the beam clamp is adjusted in the width direction and the height direction of the clamping area; the problem that components are stacked disorderly is solved, and compared with an existing beam clamp, operation is more convenient and faster; the two supporting frames are arranged on the outer sides, opposite to the clamping area, of the U-shaped rods, the U-shaped rods are connected to the supporting frames in an abutting mode, and the supporting frames are fixedly
