Abstract

(57) [Summary] [Purpose] An object of the present invention is to provide a structure of a floor portion of a ship which is excellent in heat resistance and sound absorption and has durability. [Structure] A heat-resistant paint 2 is applied on a steel plate 1, a lock wheel 3 is laid on the steel plate 1, covered with an expanded metal 4, and the expanded metal 4 is fixed with a stud pin 5 and a claw nail 6. , And further lay latex cement mortar 7 on it. The lower end of the stat pin 5 is fixed to the surface of the steel plate 1 by welding or an adhesive to fix the lock wheel 3 to the steel plate 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a floor portion which is constructed above the engine room of a ship.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, the structure of a walking floor part and floor part that is constructed on the upper part of the engine room of a ship is, as shown in FIG. 2, coated with an adhesive material 200 on a steel plate 100 and then a calcium silicate plate on it. 300 is pasted, and Rasami 400 is laid on it. In order to prevent Rasami 400 from floating, nails 500 are hammered and fixed onto calcium silicate plate 300 from above Rasami 400, and glass cloth 600 is further placed on it. Double sticking was done, and latex mortar 700 was laid on it. Since the engine room of a ship generates heat and noise from the engine at the same time, the walking floor and floor above the engine room are required to have heat resistance and sound insulation. Although the conventional structure having the calcium silicate plate 300 interposed therein has no particular problem in terms of heat resistance, the calcium silicate plate 300 has insufficient sound absorption, so that the engine room noise There was a drawback that the clogs passed through the floor and leaked to the outside. Further, the glass cloth 600 often did not fit well with the latex mortar 700 and floated.

Further, when the latex-based mortar 700 floats, cracks occur, and moisture penetrates into the cracks and reaches the steel sheet 100 through the gaps, so that the steel sheet 100 is locally corroded. was there.

[0004]

[Problems to be solved by the device]

 The present invention was made in order to solve the drawbacks described in the prior art, and an object thereof is to provide a structure of a floor portion of a ship which is excellent in heat resistance and sound absorption and has durability. .

[0005]

[Means for Solving the Problems]

 Heat-resistant paint is applied on a steel plate, rock wool is laid on it, covered with expanded metal, expanded metal is fixed with stat pins and claw nails, and latex cement mortar is laid on it. To do. The lower end of the stud pin is fixed to the surface of the steel plate by welding or an adhesive material.

[0006]

[Action]

 The stud pin securely locks the rock wool to the steel plate, and the adhesive firmly adheres the rock wool to the steel plate, so the rock rule floats up due to thermal expansion and contraction, creating a harmful gap. It never happens. Moreover, since the rock wheel has excellent sound absorption, it absorbs the noise generated in the engine room. In latex cement mortar, the latex mixed with cement mortar has a strong adhesive force and prevents the occurrence of cracks due to expansion and contraction or mechanical vibration.

[0007]

【Example】

 The present invention will be described with reference to the drawings showing an example of its implementation. As shown in Fig. 1, a heat-resistant paint 2 is applied on a steel plate 1 installed in the upper part of the engine room of a ship, a lock wheel 3 is laid on it, and an expand metal 4 is placed on it to expand it. Metal 4 is fixed with stud pins 5 and claws 6, and latex cement mortar 7 is laid on it. The lower end of the stat pin 5 is fixed to the surface of the steel plate 1 by welding or an adhesive, and the lock wheel 3 is fixed to the steel plate 1.

In the standard structure, the stud pins 5 are 6 per square meter, the crotch nails 6 are 12 per square meter, and the expanded metal 4 is fixed to the lock wheel 3. are doing. The standard thickness of the rock wool 3 is about 25 mm, and the standard thickness of the latex cement mortar 7 is about 10 mm.

[0009]

Since the present invention is configured as described above, it has the following effects.

Since the structure is such that a rock wheel is interposed, noise and vibration from the engine room can be absorbed.

Since the lock wheel is adhered to the steel plate, a gap is not formed at the interface between the two due to expansion and contraction, so that heat resistance does not deteriorate.

Since the latex mortar penetrates into the gaps between the expanded metals and has a strong adhesive force, the occurrence of cracks due to expansion and contraction, mechanical vibration, etc. is prevented. The present invention has the above effects, and its industrial utility value is remarkable.
