构成本实施例的预制混凝土构件的制作方法基本相同,以平板构件为例,如图 22 所示,包括以下步骤: The manufacturing method of the precast concrete member constituting the present embodiment is basically the same. Taking the flat member as an example, as shown in Fig. 22, the following steps are included:
( 1-1 )在预制板生产场地上,采用底模 21 ,侧模 22 ,顶模 23
,和多根用于制作纵向孔洞的纵向钢管内模 24 作模板;其中,侧模 22 每间隔一定距离向内凹,顶模 23 上开有与钢管形状尺寸相同的孔洞 231 ; ( 1-1 ) On the prefabricated board production site, the bottom mold 21, the
( 1- 2 )将底模 21 ,侧模 22 ,顶模 23
组合在一起,布置钢筋网(图中未示出),将多跟钢管内模 24 穿过一侧顶模的孔洞 231 ,穿过钢筋网的间隙,穿过另一侧顶模的孔洞;侧模内凹部分的端部 221
与纵向钢管内模 24 贴合在一起; ( 1- 2 ) the bottom mold 21 , the
( 1- 3
)在侧模、顶模和底模组成的空间内浇筑混凝土,在混凝土达到一定强度后抽出纵向钢管形成纵向贯通孔洞 9 ; ( 1- 3
Pour concrete in a space composed of a side mold, a top mold and a bottom mold, and after the concrete reaches a certain strength, the longitudinal steel tube is drawn to form a longitudinal through
( 1-4 )待混凝土达到预期强度拆除底模,顶模,侧模,形成所述的预制混凝土空心构件。 (1-4) The concrete is removed to the expected strength, the top mold, the side mold, and the precast concrete hollow member are formed.
