Abstract

The utility model discloses a light-weight bearable fire-proof wall, belonging to the ocean platform fire-proof technical field, in particular to a light-weight fire-proof wall which has fire-proof property and can bear certain structural load. The light-weight bearable fire-proof wall comprises a strengthened framework consisting of a channel steel plate and a steel wire mesh, wherein inner core insulation packing is filled in the strengthened framework, and the outer surface of the strengthened framework is coated with a concrete protective layer with a certain thickness. Compared with the prior art, the light-weight bearable fire-proof wall has the advantages of simple structure, light weight, small volume, load bearing capability, good fire-proof property, simple manufacture process and low cost, and can replace the prior ocean platform fire-proof wall.

Description

But a kind of lightweight load-bearing fire wall

Technical field

The utility model relates to ocean platform fireproof building material technical field, more particularly, but relates to a kind of lightweight load-bearing fire wall.

Background technology

It is bigger to carry out the possibility that the platform fire accident of oil and gas development operation takes place on the ocean, and marine climate easily makes fire spreading.Common prevention propagation of flame on the ocean platform at present, the measure of protection structural safety are to set up the fireproof bulkhead with protective coating or the fire wall of concrete structure form around dangerous point source.Fireproof bulkhead is to spray the topping of enough thick fireproof paint as steel plate at surface of steel plate, also needs stiffener to guarantee its stability simultaneously, and this structural cost is higher, complex process.Though the fire wall technology of concrete structure form is simple, cost is low, but also there is necessarily more formidable drawback, as: first weight is bigger, be not easy to its building operations on ocean platform, it two is that volume is bigger, has taken limited platform oil-gas mining working space, in case at high temperature its concrete peels off easily when breaking out of fire, flameproof effect is poor.So be necessary to do in this respect some new research and improvement, develop a kind of simple in structure, light weight, volume little, can bear certain structure load, be convenient to the fire wall of fabrication and installation.

Summary of the invention

Technical problem: in order to solve the weak point that above-mentioned technology exists, the purpose of this utility model provide a kind of simple in structure, light weight, volume little, can bear certain structure load, be convenient to the fire wall of fabrication and installation.

Technical scheme: in order to achieve the above object, the utility model solves the technical scheme that its technical problem adopts and is: but a kind of lightweight load-bearing fire wall is made of web frame, inner core thermal insulating filling, concrete cover.Wherein, described web frame is wrapped the troughing plate of two parallel placements and is adopted fixed form to be formed by connecting by gauze wire cloth; Described inner core thermal insulating filling is filled in the slit of leaving in the middle of two troughing plates; The be laid in external surface of the web frame that two troughing plates and gauze wire cloth form of described concrete cover.

Beneficial effect: the beneficial effects of the utility model are: steel plate is made bathtub construction, helps improving the stability of steel plate under the vertical load effect.The web frame that is made of troughing plate and gauze wire cloth can be used as the support of other structures, carries certain vertical load.Simultaneously this skeleton form can effectively prevent from the concrete spalling phenomenon that produces because of the high temperature of fire effect to guarantee the performance of outer concrete fire resistance, reduces the transmission of heat, in order to avoid steel billet temperature surpasses critical-temperature, produces unstable phenomenon.The thermal insulating filling of inner core can effectively stop the heat transmission between two block plates, can also limit the distortion of steel plate under high temperature action.Therefore this novel fire wall not only can be used as the barrier of resisting fire but also can be used as the body of wall with load-carrying properties, but has light weight, the little load-bearing of volume, good, the simple cheap advantage of manufacture craft of fireproof performance.

Description of drawings

Fig. 1 is the fire rated wall structure cross sectional view;

Among the figure: 1. gauze wire cloth, 2. troughing plate, 3. inner core thermal insulating filling, 4. concrete cover.

The specific embodiment

Shown in Figure 1, but a kind of lightweight load-bearing of the utility model fire wall is formed by strengthening aggregate, inner core filler 3 and concrete cover 4.Wherein, web frame is wrapped the troughing plate 2 of two parallel placements and is adopted welding manner to be formed by fixedly connecting by gauze wire cloth 1.Promptly earlier with troughing plate 2 wherein a placing flat on a bracing frame, and on troughing plate, apply and spread certain thickness rock wool or glass wool or other mixture; Another piece with troughing plate 2 covers then, again two troughing plate external surface wrapped wire nets 1 and with it is erected after troughing plate welding is fixedlyed connected, inner core thermal insulating filling 3 in the middle of two troughing plates of compacting, and additional fillers make between whole plate seam to be full of filler; Lay concrete cover 4 at its external surface at last, make concrete cover 4 wrap whole web frame.
