Abstract
A friction damper with adjustable height comprises a T-shaped plate, a friction material, a damping pad, an intermediate clamping plate, an outer fixing plate and a base, wherein the top of the T-shaped plate is connected with the base; the utility model discloses a friction damper with adjustable height is the shearing type, because it mainly prevents lateral shifting, but if the high form installation that then can not pass through the compression completely inadequately when the installation, through the utility model discloses a T shaped plate is connected at the top and inserts in the clearance that two friction materials formed to the height of connecting the T shaped plate at top is adjusted through the vertical shifting groove of the vertical direction on the T shaped plate to realize adjusting friction damper's height, prevent to install because of the precision problem.
Description
Technical Field
The utility model relates to a friction damper with adjustable height.
Background
The existing friction damper for construction is generally designed into a height dimension in advance according to engineering requirements, but the accuracy of the mounting position of the damper cannot be ensured due to certain deviation of construction, and the friction damper is generally high in strength and is not difficult to be mounted in a pre-compression mode.
SUMMERY OF THE UTILITY MODEL
In order to solve the prior art problem, the utility model provides a friction damper with adjustable height.
The utility model provides a technical scheme does:
a friction damper with adjustable height comprises a T-shaped plate, a friction material, a damping pad, an intermediate clamping plate, an outer fixing plate and a base, wherein the top of the T-shaped plate is connected with the base;
the outer fixing plate and the middle clamping plate are fixed on the base, two outer fixing plates are respectively arranged on two sides of the middle clamping plate to form a double-independent cavity structure, two parts of the friction material are respectively inserted into the cavity structure, and the damping pad is arranged among the friction material, the corresponding outer fixing plate and the middle clamping plate; the outer fixing plates, the middle clamping plates and the damping pads are all provided with transverse moving grooves, fixing bolts are arranged in the moving grooves, and the fixing bolts penetrate through the two outer fixing plates and the middle clamping plates and fix the friction materials among the damping pads; the top connecting T-shaped plate is inserted into a gap between the two friction material tops, the top connecting T-shaped plate is provided with a longitudinal moving groove, and the top connecting T-shaped plate is arranged in the longitudinal moving groove through a bolt.
Preferably, the bolt head of the fixing bolt is provided with a stiffening spring.
Preferably, the damping pad is fixed to the outer fixing plate or the intermediate clamping plate by bolts.
The utility model has the advantages that:
the utility model discloses a friction damper with adjustable height is the shearing type, because it mainly prevents lateral shifting, but if the high form installation that then can not pass through the compression completely inadequately when the installation, through the utility model discloses a T shaped plate is connected at the top and inserts in the clearance that two friction materials formed to the height of connecting the T shaped plate at top is adjusted through the vertical shifting groove of the vertical direction on the T shaped plate to realize adjusting friction damper's height, prevent to install because of the precision problem.
Drawings
Fig. 1 is a schematic view of the internal structure of the height adjustable friction damper of the present invention;
fig. 2 is a schematic structural view of the height-adjustable friction damper of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings, as shown in fig. 1 and 2, a height-adjustable friction damper comprises a top connection T-shaped plate 1, a friction material 2, a damping pad 3, an intermediate clamping plate 4, an outer fixing plate 5 and a base 6;
the outer fixing plate 5 and the middle clamping plate 4 are fixed on the base 6 through bolts, two outer fixing plates 5 are respectively arranged on two sides of the middle clamping plate 4, so that a double-independent cavity structure is formed, two parts of the friction material 2 are respectively inserted into the cavity structure, and the damping pad 3 is arranged between the friction material 2 and the corresponding outer fixing plate 5 and the middle clamping plate 4; the outer fixing plate 5, the middle clamping plate 4 and the damping pad 3 are all provided with transverse moving grooves 7, each transverse moving groove 7 is communicated in the thickness direction of the friction damper, fixing bolts 8 are arranged in the moving grooves 7, the fixing bolts 8 penetrate through the two outer fixing plates 5 and the middle clamping plate 4 and fix the friction materials 2 between the damping cushions 3, namely, the fixing bolt 8 is vertically fixed on the friction material 2 through a threaded opening, and the damping pad 3 is pressed with the friction material 2 through nut clamping, if a shearing force exists, the friction material 2 moves transversely to drive the fixing bolt 8 to slide in the transverse moving groove 7, but the pressure is unchanged, each damping pad 3 is fixed on the outer fixing plate 5 or the middle clamping plate 4 through a bolt fixing 10, and a stiffening spring 11 is arranged at the head of the fixing bolt for increasing the pressure and preventing the fixing bolt 8 from loosening; the top connecting T-shaped plate 1 is inserted into a gap between the tops of the two friction materials 2, the top connecting T-shaped plate 1 is provided with a longitudinal moving groove 9, the top connecting T-shaped plate 1 is arranged in the longitudinal moving groove 9 through a bolt 12, the bolt 12 can be loosened during installation, the height of the top connecting T-shaped plate 1 is adjusted, the bolt 12 is fixed after being matched with a building, the transverse moving groove 7 is transverse and is in a shearing mode, the longitudinal moving groove 9 is perpendicular to the transverse moving groove, transverse force is mainly used during use, and the longitudinal moving groove cannot influence transverse movement, so that the damping effect is influenced.
The present invention has been described in detail with reference to the preferred embodiments. However, variations and additions to the embodiments will become apparent to those of ordinary skill in the art upon a reading of the foregoing description. It is the intention of the applicant that all such variations and additions fall within the scope of the invention as claimed.
