Clamp for detecting constructional engineering waterproof material

The utility model relates to the technical field of detection fixtures, and discloses a fixture for detecting a waterproof material of constructional engineering, which comprises a base, a clamping plate and a clamping plate, the first sliding groove is formed in the top of the base; a sliding assembly is arranged in the first sliding groove, the sliding assembly comprises the detection clamp, and through sliding of the rent, when the clamping plate slides, an extrusion block makes contact with a clamping block, after the waterproof material is fixed, the clamping block and the extrusion block are clamped and fixed, and the position of the clamping plate is fixed. Compared with an existing device, only the clamping plates need to be pushed during adjustment, and use is more convenient. According to the detection clamp, if the area of a waterproof material is large, a second pull button can be pulled upwards through a lifting assembly to enable a pressing plate to move upwards, and therefore a lifting plate mo
