Abstract
The invention relates to a construction method of an apertured cast iron terrace in the terrace construction field, wherein, a foundation soil layer is arranged in the lowest layer; a concrete cushioning layer, a cement mortar bonding layer and an apertured cast iron panel layer are arranged above the foundation soil layer in sequence; the concrete cushioning layer is C15; and the cement mortar bonding layer is a 35mm-thick bonding layer in which the ratio of cement to mortar is 1 to 2. The construction method not only effectively solves the problem that the terrace is apt to crack and collapse, but also has quite high flatness, high temperature resistance and long service life and is mainly used for the design of the terrace of nonferrous metal processing shops.
Description
Technical field
The present invention relates to the construction field of terrace, specifically a kind of job practices of cast iron terrace with hole.
Background technology
In the manufacturing process of non-ferrous metal processing plant, often exist the art production process that terrace strong wear, terrace are contacted with scorching hot object, thereby cause the ordinary concrete terrace to ftracture easily, subside, yet production technology require ground to have strong cracking resistance and slump resistance energy.
Summary of the invention
The purpose of this invention is to provide a kind of job practices with a kind of cast iron terrace with hole of strong cracking resistance and slump resistance energy, this invention can not only effectively solve the problem that terrace ftractures easily, subsides, and can satisfy the requirement and the long service life of production technology.
The technical solution adopted for the present invention to solve the technical problems is: foundation soil is arranged at stratum, and the foundation soil upper strata sets gradually the concrete bed course, cement mortar setting course, porose cast iron plate surface layer.
Described concrete bed course is C15.
Described cement mortar setting course is that cement and mortar ratio are the thick setting course of 35mm of 1:2.
The invention has the beneficial effects as follows, not only effectively solved the problem that non-ferrous metal processing plant terrace for a long time ftractures easily, subsides, and also can bear the high temperature below 100 ℃ simultaneously and have higher planeness and long service life.
Description of drawings
Fig. 1 is a kind of cast iron terrace with hole organigram of cast iron terrace with hole job practices;
1. foundation soils among the figure, 2. concrete bed course, the thick 1:2 cement mortar of 3.35mm setting course, 4. porose cast iron, 5. hole.
Fig. 2 is the vertical view of porose cast iron;
The specific embodiment
In Fig. 1, earlier with the compacting of ground epibasal tier, compacting coefficient 〉=0.9.Pour into a mould the C15 concrete bed course of 100mm～200mm on the upper strata, thick 1: 2 cement mortar setting course of 35mm is that thickness is that 6mm highly is the porose cast iron plate surface layer of 25mm at last.During installation, bed course should first hacking and is cleaned clean back with water and lay setting course and surface layer, and the smooth of cast iron plate extruded and guaranteed by cement paste by the hole.Cast iron plate must keep profile neat smooth promptly do not have sand holes crackle, crack situation, and the straight-line dimension deviation of plate must not surpass ± 1mm, and diagonal is no more than ± 2mm, and the front of plate and edgewise bend degree (interplanar deviation) are no more than ± 1mm.The tensile strength of the intensity of cast iron should satisfy 1.176x10N/m
2, flexural strength satisfies 2.7x10N/m
2, Brinell hardness satisfies 143～229.
Claims (3)
1. the job practices of a cast iron terrace with hole, it is characterized in that: foundation soil is arranged at stratum, and the foundation soil upper strata sets gradually the concrete bed course, cement mortar setting course, porose cast iron plate surface layer.
2. according to the job practices of the described a kind of cast iron terrace with hole of claim 1, it is characterized in that: the job practices according to the porose a kind of cast iron terrace described in claims 1 is characterized in that: described concrete bed course is C15.
3. according to the job practices of the described porose a kind of cast iron terrace of claim 1, it is characterized in that: described cement mortar setting course be cement with mortar thickness than being the thick setting course of 35mm of 1:2.
