TH11126C3 - Prefabricated concrete parts with collapsible butyl rubber connections in keyway joints and manufacturing processes - Google Patents

Abstract

New requests, improvements Precast concrete components with collapsible butyl rubber connections in a waterproofing that Keyway joints and their manufacturing processes include: Cement grout or mortar bonding material, which is between precast concrete parts, is used to join precast concrete parts together. Provides a stronger seam and better waterproofing Butyl rubber, which is installed according to the formwork design, is half-embedded in the precast concrete block and embedded in the welded joint. Once again, the characteristics of the butyl rubber are folded according to the keyway joint pattern when installed at The butyl rubber work page (2) will collide with each other at the junction. The butyl rubber acts to prevent water seepage. Through the junction of precast concrete parts and contributes to prevent water seepage while the structure The movement And precast concrete parts

Claims (2)

Disclaimer (all) which will not appear on the advertisement page. : New request, update 1. Precast concrete parts connected by collapsible butyl rubber in the waterproofing that Keyway joints consist of - Cement grout or Marta (1) bonding material which is between precast concrete (3) and precast concrete (3) welded parts together to form a joint. Strength and well Better water seepage - Butyl rubber (2) is installed according to the formwork. The butyl rubber (2) is embedded in one half of the precast concrete (3) and the other half is embedded in the bonding material. Keyway joints, when installed at the job site, butyl rubber (2) will collide at the joint. By butyl rubber (2) acts to prevent water seeping through the junction of Precast concrete parts (3) and contribute to preventing water penetration while the structure moves - precast concrete parts (3) where cement grout or mortar (1) is made. Function to help cement concrete parts (3) together and strengthen the They are welded together as well as providing more effective protection against water seepage. 2. Production process of precast concrete parts that are connected by collapsible butyl rubber. In order to prevent water seepage at the keyway joints according to claim 1, there are steps that include The butyl rubber mounting (2) follows a formwork configuration, which features a formwork fold at the keyway junction located in Precast concrete parts (3) along the entire length of the formwork before pouring concrete in the next order, with the remaining half of the butyl rubber (2) used to prevent adhesion to other materials. Installed at the site, then pull the other half of the plastic sheet covering the butyl rubber (2) on both sides. Then, the precast concrete (3) is installed, where the butyl rubber (2) collides at the joint along its entire length, after which the cementitious grout or mortar (1 ) At the junction of precast concrete parts (3)
