Abstract
The utility model discloses a fireproofing profile steel structure which comprises a body of the steel structure. The body is provided with an inner cavity, an air discharging pipe is arranged on the upper portion of the inner cavity, a water inlet pipe is arranged on the lower portion of the inner cavity, the water inlet pipe is communicated with a water source through a water pump, a water level detector is arranged on the upper portion of the inner cavity and matched with the water pump, and meanwhile a one-way stop valve is located at the position, between the water pump and the inner cavity, on the water inlet pipe. The fireproofing profile steel structure has the advantage that a sufficient amount of water can be kept in the inner cavity.
Description
Technical field
The present invention relates to steel work technical field, especially relate to a kind of fireproof steel structure.
Background technology
At present, steel work has been widely used in building field, is especially applied on large public building.Therefore, the fire safety problem of steel work is very important.For this reason, there is producer to prevent fires by priming petock in the inner chamber of steel work.Concrete, this steel work comprises the body of steel work, and this body has inner chamber, and this inner chamber top is provided with stack, bottom is provided with water inlet pipe, and this water inlet pipe is communicated with water source.Obviously, the setting of this stack is in order to prevent the imbalance of pressure in this inner chamber.But such steel work is after long-term use, the water in its inner chamber can pass through this exhausting pipe evaporation, causes lack of water in this inner chamber, and then makes this steel work lose fireproofing function.
Summary of the invention
The object of this invention is to provide a kind of fireproof steel structure, it has the advantages that in inner chamber, to keep the sufficient water yield.
The technical solution adopted in the present invention is: fireproof steel structure, the body that comprises steel work, this body has inner chamber, this inner chamber top is provided with stack, bottom is provided with water inlet pipe, and this water inlet pipe connection water source, and described water inlet pipe is communicated to this water source by water pump, and the top of this inner chamber is provided with water level detector, this water level detector and this water pump match, and meanwhile, on this water inlet pipe, between this water pump and this inner chamber, are provided with unidirectional stop valve.
The advantage that compared to the prior art the present invention had is: in inner chamber, can keep the sufficient water yield.Once lack of water in the inner chamber of fireproof steel structure of the present invention, this water level detector sends the signal of startup to this water pump, thus this water pump to pump water in this inner chamber to keep the skin wet, avoided the situation of lack of water in this inner chamber.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the master of embodiments of the invention looks sectional view.
In figure: 10, body, 11, inner chamber; 21, water inlet pipe, 22, stack; 30, water source; 40, water pump; 50, water level detector; 60, unidirectional stop valve.
The specific embodiment
Embodiment, as shown in Figure 1: fireproof steel structure, comprise the body 10 of steel work, this body 10 has inner chamber 11, and these inner chamber 11 tops are provided with stack 22, bottom is provided with water inlet pipe 21, and this water inlet pipe 21 is communicated with water sources 30.That is, in the inner chamber 11 of this steel work, be filled with water, thereby can prevent fires, and this stack 22 can make pressure and the extraneous balance that keeps in this inner chamber 11.Further say, this water inlet pipe 21 is communicated to this water source 30 by water pump 40.That is, avoided like this 30 positions, water source must be arranged on the situation higher than the top of the peak level of this inner chamber 11, and the top of this inner chamber 11 is provided with water level detector 50, this water level detector 50 and this water pump 40 match.That is, the water level detecting in this inner chamber 11 when this water level detector 50 is lower, and this water pump 40 starts as keeping the skin wet in this inner chamber 11.Meanwhile, on this water inlet pipe 21, between this water pump 40 and this inner chamber 11, be provided with unidirectional stop valve 60.That is, the water in this water inlet pipe 21 only can enter in this inner chamber 11 and cannot reverse flow.Like this, avoided the water in this inner chamber 11 by this water inlet pipe 21, to flow backward to the situation at water source 30.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes manual of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
