Hollow structure, and it is provided with wavy buffering spring sheet wherein.
Preferably, the aluminum honeycomb panel is equipped with trapezoidal protrusion, and the side of second enhancement layer is equipped with and the protrusion
The compatible groove of shape, cooperation and the second enhancement layer card that the aluminum honeycomb panel passes through the protrusion and the groove
It connects.
Preferably, second enhancement layer is hollow structure, and the inner wall of second enhancement layer is equipped with wire mesh.
Preferably, several PVC casings are additionally provided in second enhancement layer, the PVC casing is in longitudinal arrangement described
Between wire mesh.
Preferably, expanded polystyrene foam is filled in the PVC casing.
Preferably, the gap location of the adjacent PVC casing is filled with carbon fiber.
The utility model has the following beneficial effects: the people's air defense of the utility model explosion proof door light weight, is easy dismounting group
Dress, and intensity is high, and compression strength is high, also has the effect of sound insulation damping, and doorframe uses hot rolling YH people's air defense fashioned iron, eliminates and hold
The oblique band steel of the welding procedure of pressing plate, oblique band steel, especially bearing plate and angle steel main body single hot-roll forming, bearing plate and angle steel it
Between bonding strength improve 20 times or more than the intensity of welding procedure, substantially increase closed guard gate's protective seal performance, making
Artificial consumptive material is greatly reduced when people's air defense door frame main body；Due to substantially reducing weld length, doorframe production process is avoided
The internal stress of middle generation acts on, and reduces the deflection of doorframe, improves the airtightness of closed guard gate, reduce in welding process and produce
Raw flue dust and welding slag, keeps production environment cleaner, reduces soot emissions and causes environment pollution.

Specific embodiment
It as shown in Figs. 1-5, is a kind of people's air defense explosion proof door of the utility model, including explosion-proof door body and doorframe, it is explosion-proof
Door body includes the first enhancement layer 1 and the second enhancement layer 2, and the second enhancement layer 2 is arranged in the two sides of the first enhancement layer 1 and by first
Enhancement layer 1 surrounds wherein, and the first enhancement layer 1 includes criss-cross reinforcing rib 3, and reinforcing rib 3 forms several cavitys 4, empty
It is equipped with aluminum honeycomb panel 5 in chamber 4, is hollow structure in reinforcing rib 3, and be provided with wavy buffering spring sheet 6 wherein.
Specifically, Double-layered reinforcing structure is arranged on explosion proof door, the first enhancement layer 1 is equipped with aluminum honeycomb between reinforcing rib 3
Plate 5, aluminum honeycomb panel 5 not only light weight but also have the effect of sound-absorbing sound insulation, wavy buffering elastic are provided in reinforcing rib 3
It is measuring body that piece 6 can play the role of buffering.Such as Fig. 4-5, in addition, traditional angle steel 12 welds, 1 process of doorframe is more, and time-consuming is high, weld seam
Long, consumables cost is high, and explosion-proof shock wave, airtightness are lower, and the doorframe of the utility model uses hot rolling YH people's air defense fashioned iron, removes from
