What are the basic conditions for wood flooring to enter the site?

1. Pavement ground leveling.

At the ground pavement site of the stadium, it is necessary to keep no more than 2mm uneven under the straight edge, otherwise it is necessary to adjust the level with appropriate materials. The uneven paving floor of the stadium can be leveled first by the artesian lawn.

2. Floor moisture content.

The equilibrium moisture content of the wooden floor of the gymnasium is between 6% and 14%, which should be considered in the regional climate and environment where the stadium is located. Before paving, the wooden floor of the gymnasium must be tested to see if its moisture content is qualified.

3. Paving ground humidity.

The humidity of the stadium pavement environment should be reasonable. The relative humidity of the air should be the same as that of the building, otherwise a heating and/or extraction system will be used. The difference between lower and higher relative humidity should never exceed 30.

4. Venue environment.

Generally, the wooden floor paving of the gymnasium should wait for the completion of other construction projects before starting construction, and cross construction should be avoided; At the same time, the basic construction conditions such as water, transportation, electricity, and lighting of the stadium should all be in place, and there are construction conditions for the wooden floor pavement of the stadium.

Section 1: Preparatory work before construction.

The following works must be completed before the wood floor can be installed:

1. The surface of the concrete surface layer of the base layer of the building structure should be hard, smooth, clean, dry and sand-free, and the surface flatness should be set under the concrete surface layer of the base layer of the building structure, and the wall surface at the base of the wall should also be waterproofed. Forced ventilation measures should be considered at the grassroots level to ensure that the grassroots layer is ventilated and dry.

2. The laying of wooden floors should be carried out after the completion of the ceiling project, wall decoration project, pipeline pressure test and electrical pipeline installation in the museum.

3. When fixing the sports equipment and installing the wooden floor, the embedded parts used to fix the wooden keel must be embedded accurately and firmly installed according to the requirements of the drawings.

4. The main materials and auxiliary materials (adhesives, surface coatings, anti-corrosion coatings, etc.) used in wood flooring projects should be in accordance with the design requirements, have quality certification documents and comply with the corresponding national (industry) standards, and there should be verification reports for important materials.

As the saying goes, "three points of flooring, seven points of installation" in the sports wood flooring industry. What are the installation requirements and procedures for sports wood flooring:

1. Installation requirements

1) Grassroots waterproof, moisture-proof and ant-proof strengthening measures: On the basis of the original building design structure self-waterproofing, the entire site range and the range interface may produce water seepage in the later stage are all FJS waterproof coatings, and then 150 thick concrete-L is applied as the wood floor structure G layer and waterproof protective layer, and the construction is carried out in advance to ensure that the concrete can be divided into ten dry, and continue to observe whether there is moisture return and leakage, so as to ensure that there is no leakage and moisture before the construction of the wooden floor. Coagulate the base layer:

l Termite control measures are added to ensure that the ant control is effective.

2) The horizontal flatness of the base layer of the site, the horizontal flatness of each layer of keel, and the horizontal flatness of the wool floor are controlled, and each procedure must be controlled by laser level.

3) According to the design of various sports competition equipment embedded parts and keel position accurate positioning and pay-off, installation of competition equipment to embedded parts and keel installation fasteners;

4) Precautions for installation at all levels, keel installation is the key to the sports floor, which must be stable, straight, consistent in spacing, horizontal and flat; Leave a 30mm gap between the keel and the façade to ensure the ventilation of the keel and the floor; The elastic rubber pad must be evenly laid to ensure that the elastic coefficient of the site is consistent: the joint laid by the wool wrench layer in the base layer must leave a 23mm gap; The seams of the face wrench mounting plate head should be staggered and should be relatively symmetrical to maintain beauty.

Second, the installation and construction process

Sports wood floor installation construction process: grassroots cleaning a measurement of the flatness of the ground, elastic line - embedded iron parts - installation of F layer keel, leveling - installation of sports wood floor special shock-absorbing rubber mat - laying sound-absorbing centrifugal glass wool - installation of the upper keel, leveling of a wool floor to find F installation - laying of shock absorption insulation moisture-proof film - overall surface floor paving - equipment embedded parts installation, baseboard production and installation - finishing cleanup.

1. Requirements for ground foundations:

The structural elevation of the sports floor is determined, and the height can be adjusted to 10-20mm;

The foundation requirements are basically flat, the overall horizontal difference of the floor is not more than 20 mm, and the 2m ruler is not more than 3 mm;

Before the ground floor venue is leveled, the waterproof layer of the building must be done;

The cement floor is dry and the humidity is less than 10%;

The ground is clean and clean, and there is no cargo or debris stacked;

According to the design requirements, install all kinds of sports equipment embedded parts (including the ground base part);

If the ground is designed with trunking, pipelines, etc., drawings and corresponding written instructions should be provided in advance;

Before entering the site, the owner should provide a track map of the activity stand.

2. Basic requirements for the construction site:

The construction above the floor and the fire test have ended, and there are no more projects to be constructed for the decorative ceiling, lighting and sound systems;

Indoor wall painting, sound-absorbing panels, soft packaging, glass curtain walls, painting, water, electricity, and other engineering projects have been completely completed and no longer under construction;

There shall be no water seepage and rain leakage in the venue to avoid the deformation of the floor when exposed to water;

In order to protect the product and construction quality, the floor installation adopts closed construction, which does not allow cross construction and avoids walking. Avoid duplicate construction.

The quality of the foundation ground treatment of the gymnasium has a great relationship with the installation of sports wood flooring, and the ground base is required to be flat, strong, strong and dry on the surface, so as to develop the corresponding construction plan, which has the following requirements:

1. The construction conditions of the floor base must meet the conditions stipulated in the national construction quality acceptance specification for the construction quality of the cement base in the national construction quality acceptance specification for the cement base "GB50209-2002", and the material laying work can be carried out.

2. To detect the moisture content of the ground, the moisture content of the base layer should be less than 3%, but it cannot be measured at the window or doorway, because the test value may be too low, and the depth of the test must also be noted: the suspended concrete floor is 20% deep from the surface downward; 40% depth of concrete floor;

3. The relative air humidity suitable for construction shall not exceed 60%. Use a thermometer to detect the temperature, the indoor temperature and the surface temperature should be 18 degrees, should not be below 5 degrees and above 30 degrees of construction, if the moisture barrier has been added, the relative humidity can be allowed to reach 85%, but once it exceeds 85%, it can not be laid.

The paving of the sports floor pays attention to the "right time, the right place and the right people", "the time of the day" refers to the sunny weather, and the sports floor is sunny before and after the installation, and it does not rain; "Geographical advantage" requires that the foundation ground has been thoroughly dried before laying; "People" means that pavement workers must be professional.

All aspects of the foundation of the site before the construction of the sports wood floor must meet the standards, which is the most basic requirement, and the construction site is also required to meet the following conditions in order to arrange the construction

a. The infrastructure project must be completed before the construction of the sports wood floor, and the construction site has been cleaned. The construction quality of the ground must meet the design requirements, and it should also be waterproof, moisture-proof, and air-isolated, and completely dry;

b. The indoor electricity, steam, water and ventilation projects have been installed, and the acceptance meets the design requirements and can be used normally;

c. Before the installation of sports wood flooring, the horizontal tolerance within 2m of the ground of the stadium shall not exceed 2mm;

d. Try not to cross construction, if you can't avoid cross construction, you need to reach a consensus through the relevant responsible person to form a written record to clarify the responsibility.

(1) The production conditions and safety facilities at the job site should meet the requirements of relevant standards and specifications, and the labor protection equipment of the staff should be qualified and complete.

2) Places where people often work and construction vehicles should be equipped with first-aid kits and storage of first-aid supplies, and special personnel should be designated to check, replenish or replace them frequently.

3) The safety equipment used on site should be qualified and meet the relevant requirements.

4) All kinds of operators should be informed of the risk factors and preventive measures existing on site and at work.
