Abstract
The utility model provides a steel structure. The steel structure comprises an upper steel plate and a lower steel plate, wherein a shock absorber pad is arranged between the upper steel plate and the lower steel plate, and the upper steel plate and the lower steel plate are fixed with the shock absorber pad by bolts. The steel structure provided by the utility model has the advantages that the steel plates are connected with a main structure by the bolts, and the shock absorber pad is padded, so that the damping shock absorbing effect is great, and the acoustic effect is improved.
Description
Technical field
The utility model relates to technical field of buildings, particularly a kind of steel work.
Background technology
In the prior art, in the steel work of arenas, the general mode of directly welding that adopts is installed, and owing to there is not damping shock absorption, causes acoustic efficiency not good.
The utility model content
The utility model provides a kind of damping good steel work.
To achieve these goals, the utility model provides following technical scheme:
A kind of steel work comprises: upper steel plate and lower steel plate, be provided with the damping cushion block between described upper steel plate and the described lower steel plate, and described upper steel plate, lower steel plate and described damping cushion block pass through bolt.
Preferably, be with damping washer on the described bolt, described damping washer is between the nut and described upper steel plate of described bolt.
Preferably, described damping washer is the hollow cylinder of ladder type.
Preferably, the external diameter of described damping washer equals the external diameter of nut, and the thickness of described damping washer is 25% of nut thickness.
Preferably, the penetration hole diameter of described upper steel plate is identical with the penetration hole diameter of lower steel plate, and described penetration hole diameter be bolt screw diameter 120%, to guarantee the needs of sound wave damping and installation strength.
Preferably, the perforation of the perforation of described damping washer and upper steel plate, lower steel plate is interference fit; Described damping washer and described bolt are interference fit.
By implementing above technical scheme, have following technique effect: the steel work that the utility model provides, steel plate connects agent structure by bolt, and is lined with beam between steel plate and agent structure, and damping shock absorption is effective, has improved acoustic efficiency.
Description of drawings
The structural representation of the steel work that Fig. 1 provides for the utility model.
The specific embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of steel work, as shown in Figure 1, comprise: upper steel plate 101 and lower steel plate 102, be provided with damping cushion block 103 between described upper steel plate 101 and the described lower steel plate 102, described upper steel plate 101, lower steel plate 102 are fixed by bolt 104 with described damping cushion block 103.
In other embodiments, on above-described embodiment basis, be with damping washer 105 on the described bolt 104, described damping washer 105 is between the nut 106 and described upper steel plate 101 of described bolt 104.To play better damping shock absorption effect.
In the above-described embodiments, preferably, described damping washer 105 is the hollow cylinder of ladder type, so that assembling is more stable.
In the above-described embodiments, preferably, the external diameter of described damping washer 105 equals the external diameter of nut, and the thickness of described damping washer is 25% of nut thickness.So that assembling is more stable.
In the above-described embodiments, preferably, the penetration hole diameter of described upper steel plate 101 is identical with the penetration hole diameter of lower steel plate 102, and described penetration hole diameter be bolt 104 screw diameter 120%, to guarantee the needs of sound wave damping and installation strength.
Preferably, described damping washer 105 is interference fit with the perforation of upper steel plate 101, the perforation of lower steel plate 102; Described damping washer 105 is interference fit with described bolt 104.To play better acoustic efficiency and tightness.
In addition, in the above-described embodiments, for better acoustic efficiency, also for acoustic wave energy damping action and fastening needs, damping washer 105 density are 600% of damping cushion block 103 density
More than a kind of steel work that the utility model embodiment is provided be described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, part in specific embodiments and applications all can change, in sum, this description should not be construed as restriction of the present utility model.
