The external wall latch-type deformation joint corner device (GB model: EK-J, E-EK-J series) is an expansion protection product specifically designed for irregular corners such as internal and external corners of building facades, beam-column corners, and other such locations. Its core features an integrated latch-type structure that eliminates the need for complex bolt fixation, enabling quick assembly. It is suitable for 90°-135° corner scenarios and 50-300mm seam width requirements, effectively absorbing multi-directional displacements caused by temperature changes and foundation settlement in buildings. The product consists of a 6063-T5 aluminum alloy corner base, a 1.2-2mm thick aluminum alloy/stainless steel latch cover plate, an EPDM waterstop, and an elastic sealing strip.

The roof cover type deformation joint corner joint is a customized protective device designed specifically for special nodes such as the internal and external corners of building roofs, the corner of parapets, and the intersection of high and low spans. The core consists of an integrated corner cover plate, an aluminum alloy base, a stainless steel sliding rod system, and a waterproof sealing component. The product strictly follows the node specifications on page 22 of the "04CJ01-3 Deformation Joint Atlas" and the standard "14J936 Construction of Building Deformation Joints". It achieves horizontal and vertical multidimensional displacement compensation through bidirectional sliding rod transmission, accurately absorbing structural stress caused by temperature changes, foundation settlement, and earthquakes, and avoiding cracking and leakage at the corner turning parts.

Ground locking type deformation joint corner joint is a quick installation protective device designed for special nodes such as internal and external corners of building floors, wall ground junctions, and high and low span corners. The core consists of an integrated corner locking cover plate, a reinforced aluminum alloy base, a three-dimensional adjustable buckle component, and a composite waterproof system. The product strictly follows the A/B/C/D series corner node specifications of "14J936 Deformation Joint Building Construction", and is suitable for areas with seismic fortification intensity ≤ 9 degrees. The joint width supports mainstream specifications of 25-450mm (special sizes can be customized), optimized for ground corner...

The special EPDM waterstop for deformation joint is a macromolecular waterproof sealing material specially designed for building deformation joint (expansion joint, settlement joint and seismic joint), and the core is composed of EPDM base material, reinforcing layer (nylon cord fabric/polyester fabric) and positioning installation components. The product strictly complies with Macromolecule Waterproof Materials - Part 1: Sheet Materials (GB 18173.1-2014). According to the structure, the product can be divided into three types: embedded, externally attached and removable. The width supports 200-600mm (customizable), and the thickness is 1.2-10mm. The expansion amount reaches ± 50mm, which can accurately absorb the displacement of deformation joint caused by temperature change, foundation settlement and earthquake impact. EPDM content ≥ 60%. It is widely used in the waterproof engineering of deformation joints of basements, underground garages, pools, tunnels, bridges and other buildings.
