Background technique:
For large cruise ships, it is very important to improve the vibration and noise reduction measures in the public areas of the ship, especially the public areas of the ship’s indoor sports venues, which have vibration absorption, sphere rebound, coefficient of friction, rolling load and impact resistance, etc. Performance indicators have higher requirements. Therefore, for the floor on a cruise ship, it is necessary to provide a ship floor and an installation method that has good shock and noise reduction functions, simple design, convenient construction and installation, and can shorten the construction period of the cruise ship.
Technical realization elements:
The technical problem to be solved by the present invention is to overcome the disadvantages of poor shock and noise reduction performance of the ship floor in the prior art and complicated construction, and provide a ship floor and a ship floor installation method.
The present invention solves the above technical problems through the following technical solutions:
A ship floor, the ship floor including a deck layer, characterized in that the ship floor further includes a shock absorption layer, a reinforcement layer, a connection layer and a surface layer, the shock absorption layer, the reinforcement layer, the connection layer and the surface layer The upper surface of the deck layer is successively overlapped and arranged upward, and the connecting layer is used to connect the reinforcing layer and the surface layer. The function of the damping layer is to reduce the vibration and noise. The setting of the reinforcement layer improves the structural rigidity of the ship floor and ensures the strength of the floor. The connecting layer is used to fix the surface layer set at the top and the reinforcement layer below. , The operation is convenient. The ship floor is arranged by overlapping the above-mentioned floor layers with different functions, which not only ensures the strength of the floor structure, but also has the effect of shock absorption, simple structure and convenient installation.
Preferably, the shock-absorbing layer is formed by laying a plurality of rock wool strips staggered. The use of rock wool in the damping layer can not only achieve the effect of shock and noise reduction, but also take advantage of the light weight of rock wool to effectively reduce the weight of the ship's floor and achieve maximum control of the overall weight of the ship.
Preferably, the reinforcing layer is formed by laying several steel plates, and the adjacent steel plates are connected by edge welding. The arrangement of the strengthening layer not only protects the lower rock wool, but also enhances the structural strength of the ship floor.
Preferably, a plurality of partition bars are further provided between the reinforcement layer and the shock absorption layer, and the partition bars are located directly below the connecting edges of the two steel plates. The partition strip is set directly below the connecting edge of the two steel plates, preventing the upper connecting layer from flowing from the gap between the steel plates to the surface of the rock wool and causing infiltration.
Preferably, the surface layer is formed by laying a plurality of the steel plates, and the steel plates are embedded on the upper surface of the connecting layer. The steel plate is embedded on the surface of the connecting layer, that is, the connecting layer seals the gap between each steel plate to prevent rainwater and other dirt above the surface layer from penetrating downward.
Preferably, the material of the connecting layer is an adhesive. Adhesive is a commonly used connecting agent for ships, which can effectively replace other mechanical connections such as welding and riveting, simplifying the process, reducing costs, and improving economic benefits.
Preferably, fasteners are pierced on the surface layer, and the fasteners are arranged around the edges of each of the steel plates that make up the surface layer, and the lower end of the fastener is located at the reduction. Above the earthquake layer. The installation of fasteners makes the connection between the various floor layers fully, and prevents the separation or falling off between the various floor layers caused by long-term use.
Preferably, the steel plate is an electro-galvanized steel plate.
A ship floor installation method, characterized in that the ship floor installation method is used to install the ship floor according to claim 1, and the ship floor installation method comprises the following steps:
s1, laying the damping layer on the deck;
s2, laying the reinforcement layer above the shock absorption layer, and leaving a gap between the reinforcement layer and the bulkhead of the ship;
s3. Laying the connecting layer on the upper surface of the reinforcing layer;
s4. Laminating the surface on the upper surface of the connecting layer;
s5. Use a fastener to penetrate the surface layer, and the lower end of the fastener does not touch the shock-absorbing layer;
s6. Use an adhesive to seal the gap between the surface layer and the bulkhead of the ship.
Through the above steps, the ship floor is processed and installed, and the operation is convenient. It only needs to lay the slabs from bottom to top in order to form a ship floor with shock absorption and noise reduction effect and ensure the structural strength of the floor. Installation The step operation is simple and convenient, and the practicability is strong.
