边沟模具的使用注意事项

[关闭该页][设为首页][添加收藏][发送朋友][打印][ ]

边沟模具的种类很多,无论在尺寸大小上还是在形状规格上,都有着很大的选择空间,基本可以满足所有边沟的制作,比如在形状上既有较为小型的U型、梯形和矩形边沟,也有长度可以达到2m左右的矩形边沟,这些都是较为常用的类型,而蝶形和浅碟形边沟大多安装在高速公路的两侧以满足其排水需要。从尺寸上来看,边沟模板通常有立模和平模这两个分类,立模体型较小,一般由内模和外模两个部分构成,上下通透的,结构简单,而平模体型就大了许多,因此产出的混凝土边沟容水量也会更大,使用时需要将外模固定在内模外侧,然后在外模的前后端固定上堵板,均匀地刷涂脱模剂后再灌注混凝土,与立模的使用方式不同的是,由于平模体积较大,灌浆量也相对更多,因此往往需要在混凝土中插入钢筋和吊装环,起到固定的作用,等待混凝土凝固后,混凝土和钢筋就会牢牢凝固在一起,拆模时打开边沟模板的螺栓,将外模和堵板先拆下来,使用行车勾住吊装环就可以直接取出,十分方便。

There are many kinds of side ditch molds. They have a large selection space in terms of size and shape specifications, which can basically meet the requirements of all side ditches. For example, there are small U-shaped, trapezoid and rectangular side ditches in the shape, as well as rectangular side ditches with a length of 2m left and right, which are common types. Butterfly and shallow saucer side ditches are mostly installed It is installed on both sides of the expressway to meet the drainage needs. In terms of size, the side ditch formwork usually has two categories: formwork erection and formwork erection. The formwork erection is small and generally consists of internal formwork and external formwork. It is transparent from top to bottom and simple in structure, while the form of flat formwork is much larger. Therefore, the water capacity of concrete side ditch will be larger. When using, the external formwork needs to be fixed outside the internal formwork, and then fixed and blocked at the front and rear ends of the external formwork The slab is evenly brushed with release agent and then poured with concrete. Different from the use of formwork erection, due to the large volume of flat formwork and relatively more grouting, it is often necessary to insert steel bars and lifting rings into the concrete to play a fixed role. After the concrete is solidified, the concrete and steel bars will be firmly solidified together. When the formwork is removed, open the bolts of side ditch formwork The outer mold and the blocking plate are removed first, and can be taken out directly by using the crane to hook the lifting ring, which is very convenient.

边沟模具在使用中需要注意些什么呢?首先就是施工的步骤,需要先检查U型渠模具是否有积累污物或者损坏,没有问题再投入使用,按照组装模具、刷脱模剂、震动排气、晾晒拆模的顺序进行,注意震动过程中需要保证气泡充分冒出,同时要尽量保持振动棒不直接碰触模具的表面,以防止其高速震动划伤模具,影响产出U型渠预制件的光滑程度。还有就是使用后的清洁和保养,需要及时清理U型渠模具内残留的混凝土,以防止其凝固在模具中,影响下一次浇筑的混凝土的配比和成型,所以需要使用专用的清洁剂来清洗,如果难以去除可以使用刷子进行刷洗,在清洗中要注意力度,不要因为用力过大而划伤模具,清洗干净涂好保护油就可以存放到干燥通风的仓库中了。

What should be paid attention to when using the side ditch mold? First of all, it is the construction step. First, it is necessary to check whether the U-shaped channel mold has accumulated dirt or damage, and then put it into use if there is no problem. It shall be carried out according to the sequence of assembling the mold, brushing the release agent, vibrating exhaust and drying the mold. During the vibration process, it is necessary to ensure that bubbles fully emerge, and at the same time, it is necessary to keep the vibrator from directly touching the surface of the mold to prevent its high-speed vibration scratch Damage to the mold will affect the smoothness of U-shaped channel prefabricated parts. There is also the cleaning and maintenance after use. It is necessary to clean the residual concrete in the U-shaped channel mold in time to prevent it from solidifying in the mold, which will affect the proportion and molding of the next pouring concrete. Therefore, it is necessary to use a special cleaner to clean it. If it is difficult to remove it, it can be brushed with a brush. During cleaning, it is necessary to pay attention to the strength, and do not scratch the mold due to excessive force It can be stored in a dry and ventilated warehouse after being cleaned and coated with protective oil.
