The Chinese invention patent with the publication number CN201276203Y and the publication date of July 22, 2009 discloses a maintenance system for an integral asphalt ship, including a cabin, which is characterized in that it also includes an independent interior that can be installed in the cabin and can be insulated. For the gallbladder structure, the manual discloses that rock wool was once used as the heat insulation material in the heat insulation design of the integral asphalt ship cargo hold, but the water absorption rate of rock wool is high, and it is easy to mildew after long-term water absorption, and the internal silk floss delaminates, and the heat insulation fails
In order to prevent the rock wool from contacting with the cargo to absorb water, the patent designed an additional layer of a complete airtight cargo tank liner thin steel plate on the surface of the rock wool, but this eventually caused the heated air in the rock wool confined space to expand and cannot breathe. Therefore, it leads to the problem of deformation of the reverse hull structure
Therefore, the thermal insulation problem of the monolithic asphalt ship cargo hold has not been completely solved

Embodiment Construction

[0024] The present invention will be further clarified below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. Modifications of equivalent forms all fall within the scope defined by the appended claims of this application.

[0025] like Figure 1 to Figure 3 As shown, an integral thermal insulation cabin of an asphalt ship includes a cargo hold, and an open thermal insulation structure is arranged inside the cargo hold. The open thermal insulation structure includes foam glass, galvanized sheet steel, fastening studs and flat steel. The solid studs are vertically welded to the inner wall of the cargo hold. Corresponding through holes are formed in the foam glass and galvanized sheet steel. The foam glass is distributed on the inner wall of the cargo hold in several zigzag structures. Each zigzag structure in...

Abstract

The invention discloses an integral heat insulation and heat preservation cabin of an asphalt ship and a construction method thereof.The integral heat insulation and heat preservation cabin comprises a cargo hold, an open type heat insulation and heat preservation structure is arranged in the cargo hold and comprises foam glass, galvanized thin steel plates, fastening studs and flat steel, the fastening studs are vertically arranged on the inner wall of the cargo hold, and the flat steel is arranged on the inner wall of the cargo hold; corresponding through holes are formed in the foam glass and the galvanized thin steel plates, the fastening studs sequentially penetrate through the through holes in the foam glass and the galvanized thin steel plates and are pressed and fixed through the nuts and the flat steel, and gaps are reserved between the galvanized thin steel plates. The thermal insulation effect is good, the ship body structure cannot be damaged, and the safety coefficient of the integral cargo hold asphalt ship during transportation is improved.

Description

technical field [0001] The invention relates to the field of ship design, in particular to an integral thermal insulation cabin of an asphalt ship and a construction method thereof. Background technique [0002] At present, there are two types of cargo holds for asphalt carriers in the world. The independent cargo hold structure is connected to the hull through pads and supports. It is not a necessary part of the hull structure and can be understood as being built in the main hull structure. A separate closed structure acts as a cargo hold. The advantage of the independent cargo hold is that the thermal insulation material can be arranged on the outer bulkhead of the cargo hold, which is not affected by the internal cargo. The thermal insulation design is simple in material selection and convenient in maintenance. However, the disadvantage of the independent cargo hold is the construction of an additional set of independent cargo hold structures, which largely wastes space ...
