Step Grooved Concrete Nail Easy To Install And Remove

In order to improve the temperature of the outlet of the Step Grooved Step Grooved Concrete Nail, should be given priority to the mixing of water heating, if not meet the requirements to consider aggregate heating; cement can not be directly heated.

When the mixed water heating, the water temperature should not exceed 60 ℃, such as more than 60 ℃, should change the feeding order: the aggregate and water first mix, and then add cement, so as not to cause cement fake condensate, affecting the quality of Step Grooved Step Grooved Concrete Nail.

Aggregate heating of aggregate is generally used to pass hot water or steam heating. Aggregate heating the maximum temperature should not exceed 60oC. When steam is used, the coarse aggregate can be heated directly, but it does not affect the water-cement ratio of the Step Grooved Step Grooved Concrete Nail.

Before mixing the Step Grooved Step Grooved Concrete Nail with hot water or steam, the mixing machine should be washed and the mixing time should be about 50% longer than that of the general season. Winter Step Grooved Step Grooved Concrete Nail transport should be as much as possible to reduce the number of transshipments, it is best to take a direct delivery. Transport equipment should have reliable wind protection measures, and as much as possible to be insulated. A variety of transport equipment at the end of the work, you must immediately rinse with steam or hot water; restore the work of the first heating.

Winter frost prevention measures for Step Grooved Step Grooved Concrete Nail pouring are mainly heat storage method and greenhouse method. Thermal storage method is generally applicable to the temperature above -10 ℃, the greenhouse method for the temperature below a 10 ℃.

The heat storage method is to heat the material with a low thermal conductivity on the outer surface of the Step Grooved Step Grooved Concrete Nail pouring block, and the heat source is the heat and cement hydration heat of the pre-added Step Grooved Step Grooved Concrete Nail composition. Construction of the template should be insulation template, pouring the top of the Step Grooved Step Grooved Concrete Nail, to immediately cover the use of insulation materials. The thermal insulation method is essentially a surface insulation method, which is consistent with the surface protection of Step Grooved Step Grooved Concrete Nail dams, but its purpose and requirements are different. The purpose of surface protection is to prevent the surface cracks of Step Grooved Step Grooved Concrete Nail, which requires that the internal temperature difference of Step Grooved Step Grooved Concrete Nail does not exceed the allowable standard. The purpose of the thermal storage method is to prevent the surface of the Step Grooved Step Grooved Concrete Nail frost damage, which requires the Step Grooved Step Grooved Concrete Nail surface temperature is not lower than its normal solidification hardening temperature.

The shed is a Step Grooved Step Grooved Concrete Nail Nail shed in a Step Grooved Step Grooved Concrete Nail pouring position.

The warm shed is mainly composed of shed cover, support structure and insulation structure of the insulation layer. We usually use three types. The banded shed is a simple warm shed. With 10 × 10cm prefabricated Step Grooved Step Grooved Concrete Nail column for support, high 3.5 ~ 4.Om. The shed is covered with round logs. Insulation layer with straw, straw and canvas and so on. The roof of the Step Grooved Step Grooved Concrete Nail under the mouth of the activities of the mouth of the mouth, and sacks and bags of straw mat insulation.

Assembled shed, the shed with a single piece of steel truss assembled. Because of its large span, the support structure can be set aside from the template. The roof shall also be provided with a Step Grooved Step Grooved Concrete Nail discharge opening and a movable mouth cover.

The installation of warm shed, including steel truss composite beams, stereotypes insulation support structure, lifting structure and envelope structure and other parts. The entire shed is an integral hoisting unit. Its main advantage is easy to install and dismantle.
