Abstract
A vibration reduction fixing device of a light steel joist comprises a fixing seat (10) used for being fixed with a building, a joist installation seat (20) used for installing the light steel joist, and a vibration reduction unit (30) which is arranged between the fixing seat (10) and the joist installation seat (20) and connects the fixing seat (10) and the joist installation seat (20) into a whole. The vibration reduction fixing device adopts a steel outer shell and is strong in corrosion resistance. A vibration reduction pad separates a wall surface from the light steel joist, so that rigid connection is eliminated. A bolt fixes the outer shell of a shock absorber and a pinch plate, the completeness of a system after vibration reduction materials are burnt under limiting situations like a fire disaster is taken into account, and the situation that workers are injured due to the fact that light steel joist collapses is avoided.
Description
Technical field
The utility model relates to structure design, the buffering fixed structure when particularly lightgage steel joist is installed.
Background technology
Lightgage steel joist generally is to adopt and the direct-connected mode of metope in the prior art, do not design vibration reducing measure, because the walling system of metope and lightgage steel joist combination is when thickness is certain, the air sound insulation factor is limited, therefore, can't satisfy high performance requirement, simultaneously, lightgage steel joist directly is connected with body of wall, produces the overhead speaker of rigidity, be very disadvantageous to sound insulation, soundproof effect is poor.
Summary of the invention
The utility model provides a kind of vibration damping fastening devices of lightgage steel joist, adopts and adds buffer structure in fastening devices, solves the not good technical problem of soundproof effect in the prior art.
The utility model for the vibration damping fastening devices that this lightgage steel joist that provides is provided comprise for the fixing holder of building, the damper unit that is used for that the keel mount pad of lightgage steel joist is installed and is arranged between the two and both are connected as one.Described holder is for being converted into the sheet material of " U " shape, a sidewall that is somebody's turn to do " U " shape holder is the fixed head fixing with building, this fixed head is provided with fixed hole position, and another sidewall relative with fixed head is first Connection Block that is connected with the keel mount pad with damper unit on this " U " shape holder.Described damper unit is for making the elastic body of " U " shape, described first Connection Block inserts and is somebody's turn to do in the middle groove of " U " shape elastic body, described keel mount pad comprises second Connection Block that is " U " shape and the keel installing plate that is come out by bending on sidewall of this second Connection Block, described second Connection Block is buckled in described elastomeric outside, and described keel installing plate is provided with mounting hole site.Two sides of described first Connection Block outwards are bent with baffle plate respectively, at least part of damper unit is stuck between these two baffle plates, described damper unit also includes connecting bolt, and this connecting bolt connects as one above-mentioned three parts by the fixing hole on first Connection Block, elastic body and second Connection Block.
Buffering fastening devices of the present utility model adopts steel shell, corrosion resistance is strong, cushion blocking will disconnect between metope and the lightgage steel joist, eliminated and be rigidly connected, bolt is fixed together shock absorber shell and buckle, considered that (such as fire) damping material can not made lightgage steel joist collapse and cause injury to personnel by the integrality of system after being burnt under the limiting case.
Description of drawings
Fig. 1 is the perspective exploded view of the utility model vibration damping fastening devices.
Fig. 2 is schematic diagram of the present utility model.
The specific embodiment
In conjunction with above-mentioned description of drawings specific embodiment of the utility model.
By among Fig. 1 and Fig. 2 as can be known, the vibration damping fastening devices of this lightgage steel joist comprise for the fixing holder 10 of building, the damper unit 30 that is used for that the keel mount pad 20 of lightgage steel joist is installed and is arranged between the two and both are connected as one.The utility model adopts the method that damper unit is set between two connection fasteners, avoid lightgage steel joist and body of wall to be rigidly connected, and cuts off the sound transmission passage, thereby reaches the effect of sound insulation.
By among Fig. 1 and Fig. 2 as can be known, described holder 10 is for being converted into the sheet material of " U " shape, a sidewall that is somebody's turn to do " U " shape holder 10 is the fixed head 11 fixing with building, this fixed head 11 is provided with fixed hole position 111, should " U " shape holder 10 on another sidewall relative with fixed head 11 be first Connection Block 12 that is connected with keel mount pad 20 with damper unit 30.Described damper unit 30 is for making the elastic body 31 of " U " shape, in the groove in the middle of described this " U " shape elastic body 31 of first Connection Block, 12 insertions, described keel mount pad 20 comprises second Connection Block 21 that is " U " shape and the keel installing plate 22 that is come out by bending on 21 1 sidewalls of this second Connection Block, described second Connection Block 21 is buckled in the outside of described elastic body 31, and described keel installing plate 22 is provided with mounting hole site 221.U-shaped elastic body 31 is installed on the holder 10 between two parties, second Connection Block 21 is installed on the elastic body 31 between two parties, use expansion bolt or other modes by fixed hole position 111 that whole vibration damping fastening devices is fixing on the wall; Lightgage steel joist is close on keel installing plate 22, and adjusts the front and back position of lightgage steel joist, guarantee the basal plane level; Adopt modes such as screw or rivet by mounting hole site 221 lightgage steel joist to be fixed on the vibration damping fastening devices, adopt mode commonly used that the facing plate on surface is installed at last.
By among Fig. 1 and Fig. 2 as can be known, two sides of described first Connection Block 12 outwards are bent with baffle plate 121 respectively, at least part of damper unit 30 is stuck between these two baffle plates 121, described damper unit 30 also includes connecting bolt 32, and this connecting bolt 32 connects as one above-mentioned three parts by the fixing hole on first Connection Block 12, elastic body 31 and second Connection Block 21.Baffle plate 121 will be fixed the run location of elastic body 31; The bending up part and also will control relative position with elastic body 31 of second Connection Block, 21 two ends; Connecting bolt 32 is passed fixing hole with all parts strings together, and with nut that all parts are locked.
Above content be in conjunction with concrete preferred embodiment to further describing that the present invention does, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
