Steel templates, also known as (disassembly template network), can replace wood templates, significantly reduced the exclusion of pore water pressure and bubbles in concrete pressure in traditional sealing templates such as wood, plywood, or steel plates;After the structural concrete is poured, a ideal rough interface is formed.
Steel template design
Bridge steel template design principles: 1. Reasonableness must consider the pouring process in actual use, whether it is applicable and can meet the quality requirements, the focus is as follows: 1) the steel template resistance strength is sufficient, not lower than the actual anti -curved strength strength2 to 3 times; 2) minimize the seams as much as possible, and use large templates as much as possible under the conditions of construction conditions (hanging capacity, transportation conditions, etc.) as much as possible to reduce the installation and demolition workload and facilitate the construction of construction.3) When the steel mold connection is designed, a certain number of positioning and sales should be set, which is conducive to the control of the template to sew.4) To prevent seepage, the connection part of the two templates should be designed as yin and yang overlap.2. Although the standardization of each structure is different and the size is different, as the number of tasks increases and the variety increases, the overall division of the main section shape, vertical shape and size range (or several basic shapes) can be performed.Class is combined with a standard form template and matching template combination to meet the size requirements and achieve the purpose of construction to reduce template investment.This requires that the main raw materials, steel plate thickness, tendon thickness, tendon pitch, connecting pores, and hole spacing are relatively fixed.
Steel template weight
Steel template specification
The cross -section of one -way force -type steel template is generally ladder -wave shape, and its specifications are generally: 0.75 ~ 1.6mm, the thickest is 3.2mm; the width of the board is 610 ~ 760mm, and the widest is 1200mm;The maximum is 160mm; the rib width is 52 ~ 100mm; the span of the board is from 1500 ~ 4000mm, the most economical span is 2000 ~ 3000mm, and the maximum span is 12000mm.The weight of the board is 9.6 ~ 38kg/m2.The two -way force pressure steel mold shell is generally made of a square box -shaped shell from 0.75 ~ 1mmq235 thin steel plate, and its specifications are determined according to the floor structure design.The pressure -type steel template for a combination board, the average width of the groove (ribs) of the pouring concrete should not be less than 50mm.When a nail is set in the groove, the total height of the voltage steel plate should not exceed 80mm.
Steel template price
The processing fee is about 2000/ton, and the price of the finished product is 5500-6500 yuan/ton. It depends on the type of the template is a pier pillar template, a national standard template or a box beam template.many factors.
