Background technique
In use there are a lot of deficiencys in crane span structure in the technology now, mainly show the following aspects: 1, crane span structure adopts the common iron manufacturing to form usually, baking vanish or zinc-plated processing are merely carried out in the crane span structure surface, these two kinds of methods can not guarantee the long-term non-corrosive in crane span structure surface, crane span structure generally is no more than 1 year and will gets rusty, thereby shortened working life of crane span structure, cause the less stable of crane span structure.2, after no matter crane span structure adopts hot-galvanizing or baking vanish, the crane span structure surface all can produce very strong reflective, thereby produces light pollution, particularly in the local time being used for tunnel, airport, bridge etc., bury bigger potential safety hazard, when the light of vehicle crosses, had bigger danger.3, because the crane span structure of prior art adopts the common material manufacturing to form, make that the intensity of crane span structure is low, bearing capacity is poor, in case as breaking out of fire, the temperature of crane span structure will rupture when reaching 800～1000 ℃, the circuit interruption that causes ground such as tunnel, airport, the disaster relief can't smooth implementations, make that loss is huge.And because the thickness a surname of crane span structure, the bearing load of most of crane span structure is lower, mostly adopts the Q235 steel at present both at home and abroad, and support uses angle bar to make, and is fixing by welding, and causes the variable of crane span structure big, unstable, has bigger potential safety hazard.
The model utility content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and is easy for installation, the Safety performance height, and bearing capacity is strong, the fireproof bridge frame that heat distortion amount is little.
The technical scheme in the invention for solving the above technical problem is: this fireproof bridge frame comprises two bridge limit rails and some reinforced steels, described two bridge limit rails are parallel to each other, described reinforced steel is fixed between two bridge limit rails, its characteristics are: also comprise two connecting sheets, one end of described two bridge limit rails is provided with attachment hole, described two connecting sheets are separately fixed at the other end of two bridge limit rails, be provided with the connection film perforation on these two connecting sheets, described connection film perforation and attachment hole are complementary, and described two connecting sheets are complementary with an end of two bridge limit rails respectively.
Bridge described in the utility model limit rail and reinforced steel are S20C alloyed steel material.
The utility model also comprises the high low pressure beam, and described high low pressure beam is fixed on the reinforced steel, and this high low pressure beam is between two bridge limit rails.
The other end of two bridge limit rails described in the utility model is provided with mounting groove, and described two connecting sheets are separately fixed in the mounting groove of two bridge limit rail the other ends.
Have the ligation hole in the reinforced steel described in the utility model, described high low pressure beam is fixed on the reinforced steel by the ligation hole.
High low pressure beam described in the utility model parallels with bridge limit rail.
Spacing between high low pressure beam described in the utility model and the bridge limit rail is greater than the spacing between this high low pressure beam and another root bridge limit rail.
Connecting sheet described in the utility model is a S20C alloyed steel material.
High low pressure beam described in the utility model is a S20C alloyed steel material.
The utility model compared with prior art has the following advantages and effect: simple in structure, reasonable in design, and the Safety performance height, bearing capacity is strong, and heat distortion amount is little.Long service life, the mechanical strength height, bearing capacity is strong, and average bearing capacity can reach 30 kilograms every meter load.
Installation and removal of the present utility model are very convenient, be convenient to safeguard and maintenance that during installation, only several fireproof bridge frames need be joined end to end gets final product, get final product as the connecting sheet in the previous fireproof bridge frame is connected with attachment hole in the back fireproof bridge frame, thereby improved working efficiency.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment:
Referring to Fig. 1 to Fig. 6, fireproof bridge frame in the present embodiment comprises two bridge limit rails 1, high low pressure beam 2, some reinforced steels 3 and two connecting sheets 4, and wherein bridge limit rail 1, high low pressure beam 2, reinforced steel 3 and connecting sheet 4 all adopt the manufacturing of S20C alloy steel material to form.
Be parallel to each other between two bridge limit rails 1 in the present embodiment, reinforced steel 3 is fixed between two bridge limit rails 1, and promptly an end of reinforced steel 3 is fixed on the bridge limit rail 1, and the other end of this reinforced steel 3 is fixed on another root bridge limit rail 1.Have ligation hole 31 in reinforced steel 3, high low pressure beam 2 is fixed on the reinforced steel 3 by ligation hole 31, and this high low pressure beam 2 is between two bridge limit rails 1, and high low pressure beam 2 parallels with bridge limit rail 1.Spacing between high low pressure beam 2 and the bridge limit rail 1 is greater than the spacing between this high low pressure beam 2 and another root bridge limit rail 1, that is to say that high low pressure beam 2 becomes asymmetric distribution with distance between two bridge limit rails 1.
An end of two bridge limit rails 1 is provided with attachment hole 5 in the present embodiment, is provided with 6, two connecting sheets 4 of mounting groove at the other end of two bridge limit rails 1 and is separately fixed in the mounting groove 6 of two bridge limit rail 1 the other ends.Be provided with on two connecting sheets 4 in the present embodiment and connect film perforation 41, connect film perforation 41 and attachment hole 5 and be complementary, two connecting sheets 4 are complementary with an end of two bridge limit rails 1 respectively, make can join end to end between several fireproof bridge frames.
Fireproof bridge frame in the present embodiment adopts the S20C alloyed steel as material, makes that the high temperature deformation amount of crane span structure is very little, and in general when 1000 ℃ of high temperature, the per 6 meters amount of deformation of this crane span structure is no more than 70mm ~ 100mm.In use not reflective, can not produce light pollution, the effect that particularly is used in tunnel, submerged tunnel or the deep-well is more obvious.
Fireproof bridge frame reliable performance in the present embodiment, as this crane span structure initiation fire in use, the cable that can guarantee to be installed on the crane span structure can not interrupt in 2 hours, thereby bring more facility for the stand-by service of fire, illumination can be provided or rescue power equipment to other and carry out electric power input as place, thereby can reduce loss at insufficient lights such as tunnels.Long service life can effectively keep non-corrosive in 30 years.
