Construction preparation of the laser screed flooring

1 Before the concrete laser screed flooring is seamlessly constructed, the drawings shall be reviewed and a special construction plan shall be formulated.

2 The super-large area concrete ground seamless construction plan should include the following main contents:

a) The temperature effect of the concrete pouring body can be calculated according to the calculation method of seamless construction temperature;

b) the conditions for controlling the crack can be determined according to the concrete crack control conditions;

c) The gap between jumps can be calculated according to the jump interval and the concrete stress calculation method, and combined with the specific conditions of the site;

d) The temperature stress and shrinkage stress of the concrete pouring body can be calculated according to the jump interval and the concrete stress calculation method;

e) main anti-crack construction measures and temperature control indicators;

f) monitoring equipment and test layout drawings;

g) raw material optimization, mix design, preparation and transportation;

h) concrete pouring sequence;

i) Concrete insulation and moisturizing maintenance measures;

j) major emergency safeguards;

k) Construction measures under special conditions and special climatic conditions.

Site meeting of laser screed flooring

3 Before the concrete laser screed flooring work is seamlessly constructed, professional training should be carried out for the construction personnel, technical delivery should be carried out step by step, and a post responsibility system and a handover system should be established.

4 The construction site facilities shall be arranged according to the requirements of the general layout plan of the construction and completed on time. The roads in the site shall be solid and flat, and the water supply and power supply shall meet the needs of continuous concrete construction.

5 Before the concrete is poured, the seamless construction equipment shall be inspected and commissioned, and its performance and quantity shall meet the needs of continuous concrete pouring.

6 Concrete temperature monitoring equipment should be calibrated and debugged normally, insulation materials should be available, and special personnel should be assigned to manage temperature measurement.

7 Before the concrete floor is seamlessly constructed, it should contact the local meteorological station and station to grasp the recent meteorological conditions. Emergency construction plans shall be formulated for construction under special conditions.
