目前广泛应用的定型组合钢模板中,有一种代号为“J”的连接角模(以下简称角模),其主要作用是在混凝土构件90°阳角位置连接代号为“P”的平模,它只起固定模板作用,不接触混凝土,也不起使混凝土成型的作用。工程实践中,我在几个常见的特殊部位采用角模作为接触混凝土的模板,使混凝土成型,收到了非常好的效果。只是要在角模U形卡孔处采取防止漏浆措施,如铺贴油毡条等。一、用于空心板间的吊缝当空心板间有小于40毫米缝隙需灌细石混凝土时,可用铅丝将角模吊绑在板下作模板,见图1。其特点是拆装方便,混凝土不凸出板底,节约木材。
Among the widely used fixed combination steel templates, there is a connection angle model code named “J” (hereinafter referred to as “angle mold”) whose main function is to connect the code name “P” to the 90° angle position of the concrete structure. The flat die, which only acts as a fixed template, does not touch the concrete nor does it serve to shape the concrete. In engineering practice, I used corner moulds as template for contact with concrete in several common special locations to form concrete and received very good results. It is only necessary to take measures to prevent the leakage of pulp at the corners of the U-shaped hole of the corner die, such as laying linoleum strips. First, for the gap between the hollow plate between the hollow plate when there is less than 40 mm gap between the need to pour fine stone concrete, the lead can be used to hang the angle die tied under the board as a template, see Figure 1. It is characterized by easy disassembly and assembly, the concrete does not protrude from the bottom of the board, and saves wood.
