Many people don't know much about the construction of floor concrete warehouse joints, and here is an introduction related to this, which can be read and collected by interested family and friends.
The construction of floor concrete sub-silo joints refers to the setting of separation joints in the concrete ground to balance the shrinkage and temperature change of the concrete and prevent the ground from cracking and deformation. Here are the detailed steps and technical points of this construction process::
Construction steps: 1. Design the silo joint: determine the position and spacing of the silo joint according to the ground size and use requirements. Normally, the spacing of the sub-silo joints should be 20 30 times the thickness of the concrete floor, and the width should be 1 4 1 3 times.
2.Preparation: Clear the ground, remove debris and sediment. Make sure the ground is level and remove any bumps or depressions.
3.Foundation treatment: If there are large undulations or holes in the ground, foundation treatment can be carried out. Fill holes and repair uneven ground to ensure a level floor.
4.Installation template: According to the design requirements, install the sub-silo seam template on the ground. The formwork can be made of wood or steel plates, ensuring that the formwork is sturdy and properly installed.
5.Pouring concrete: Set a protective frame around the formwork, and then pour it according to the concrete construction plan. According to the design requirements, select the appropriate concrete mix ratio to ensure the quality of concrete.
6.Grinding and polishing: After the initial setting of concrete, a polishing machine is used to grind and polish the ground. This will level the ground and increase the brightness and ease of cleaning of the floor.
7.Stripping formwork: After the concrete reaches sufficient strength, the installed sub-silo joint formwork can be removed. Make sure the stencil is completely peeled off and no residue is left behind.
8.Crack treatment: Check the ground for cracks, and if necessary, repair with caulk or patch.
Technical points: 1. The position and spacing of the sub-silo joints should be determined according to factors such as ground size, temperature change and concrete shrinkage rate to ensure the overall stability of the ground.
2.The mix ratio of concrete should meet the design requirements to ensure that the concrete has good fluidity and strength, and can withstand the pressure and stress of the ground.
3.The installation of the silo seam template should be firm and reliable to ensure that the size and shape of the silo seam meet the design requirements.
4.When pouring concrete, it is necessary to pay attention to the pouring speed and uniformity to avoid the phenomenon of concrete compartments and premature dehydration.
5.The process of grinding and polishing concrete should be uniform and meticulous to avoid abrasion, scratches or unevenness on the ground.
6.Care should be taken when peeling off the formwork so as not to damage the concrete surface or the edges of the split joints.
7.Crack treatment should be carried out in time to avoid the aggravation and expansion of cracks, and the cracks can be repaired with caulk or repair agent.
The construction of floor concrete silo joints needs to comprehensively consider factors such as ground size, temperature change, concrete shrinkage rate, etc., to ensure the flatness, stability and durability of the ground. At the same time, it is necessary to pay attention to the details during the construction process to ensure the correct implementation of each step to obtain high-quality floor concrete silo joints.
