Embodiment Construction
[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] see first figure 1 with figure 2 As shown, the epoxy resin cement concrete structure at the joint of the prefabricated basement exterior wall of the present invention includes the prefabricated wall 11 of the basement exterior wall, the prefabricated wall 11 is reserved with a connecting steel bar 12 at the joint, and the adjacent prefabricated wall 11 The connecting steel bars 12 are connected by threaded sleeves 120, and epoxy resin cement concrete 13 is poured at the joints to connect the prefabricated walls 11 of the two basement exterior walls. The epoxy resin cement concrete 13 has excellent dimensional stability and excellent Excellent interfacial bonding performance, effectively solving the problem of water leakage at the joints. The surface of the epoxy resin cement concrete 13 is coated with epoxy resin (epoxy resi...

The invention discloses epoxy resin cement concrete used at the position of a prefabricated basement exterior wall joint and a construction method thereof. The method comprises the steps of mounting prefabricated walls and reserving connecting rebars at prefabricated wall joints; connecting and fixing the connecting rebars on adjacent prefabricated walls with threaded sleeves; erecting formworks on the two sides of each prefabricated wall joint; pouring the epoxy resin cement concrete in the formworks; dismounting the formworks after the epoxy resin cement concrete is polymerized into films; coating the surface of the epoxy resin cement concrete with epoxy resin and pasting a layer of glass fiber cloth; coating the surface of the glass fiber cloth with a layer of epoxy resin cement gum. According to the epoxy resin cement concrete used at the position of the prefabricated basement exterior wall joint and the construction method thereof, two basement exterior walls are connected through the epoxy resin cement concrete, and the excellent dimensional stability and interface bonding performance of the epoxy resin cement concrete can effectively solve the problem of water leakage at the position of the joint.
Description
technical field [0001] The invention relates to a construction method for solving water leakage at joints of prefabricated basement exterior walls, in particular to a structure of epoxy resin cement concrete at the joints of prefabricated basement exterior walls and a construction method thereof. Background technique [0002] Prefabrication technology has gradually been widely used in frame structures, above-ground wall structures, etc., but there are still many limitations in applying to underground structures. The completed walls are transported to the construction site and spliced one by one. The anti-seepage at the joints has become the main technical difficulty in the application of prefabricated structures. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a structure and construction method of epoxy resin cement concrete at the joints of the prefabricated basement external walls that can solve the problem ...
