Problems solved by technology

However, it still cannot reflect the change of thermal deformation of the lap joint, and the data cannot directly reflect the influence of thermal deformation on the structure of waterproof membranes.
[0005] Therefore, there is a lack of a test method in the prior art that can reflect the thermal deformation of the lap joint and can directly reflect the impact of thermal deformation on the structure of the waterproof membrane.

Abstract

The invention discloses a test method for thermal deformation of a lap joint of waterproof coiled materials. The test method comprises the following steps of sample piece cutting, test piece preparation, thermal treatment and measurement. The device has the beneficial effects that in the thermal deformation process of the test piece, the test piece is fixed through the fixing piece, the state of the waterproof coiled material after fixed construction is simulated, the bonding lap joint position of the main body part sample piece and the lap joint position sample piece is subjected to thermal deformation to generate an opening, and the deformation direction and length of the opening are measured to obtain the waterproof coiled material. And the thermal size deformation condition of the main body part sample piece and the lap joint part sample piece after construction and fixation can be intuitively reflected. Therefore, the thermal deformation condition of the overlap edge can be reflected, and the influence of thermal deformation on the waterproof roll structure can be visually reflected.

Description

technical field [0001] The invention relates to the technical field of test methods, in particular to a test method for thermal deformation of lap joints of waterproof coiled materials. Background technique [0002] Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills and other facilities, and it is a flexible building material product that can be rolled into rolls to resist external rainwater and groundwater leakage, as an engineering basis The leak-free connection with the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. Due to the various use environments of waterproofing membranes, requirements are put forward for the dimensional change rate of waterproofing membranes under different temperature environments, and it is also necessary to conduct thermal deformation tests on waterproofing membranes. [0003] In the current test of the waterproof membrane, the test pie...
