Abstract
Provided is a sound barrier supporting device casting a base and stand columns together. A base and a foundation are connected through a vibration damping rubber mat. Thus, after the base is connected with the foundation through the vibration damping rubber mat and is stressed, a groove can accommodate the squeezed and deformed portion of the vibration damping rubber mat, and pressure can be released conveniently; a base body is provided with an installation hole of a foundation bolt and also provided with a threaded hole in the process of replacing the vibration damping rubber mat, and therefore when the vibration damping rubber mat is replaced, the base can be supported after the bolt is screwed in; and coaxial positioning pin holes are formed in the vibration damping rubber mat and the base in an opposite mode, and therefore positioning pins can be used conveniently to limit shift of the rubber mat when the rubber mat is stressed in the process of use.
Description
[0001] technical field
The utility model discloses and a kind of base and column is cast in together sound barrier bracing or strutting arrangement, and especially base lower surface has groove, so as base by the vibration damping rubber cushion with basic be connected stressed after, make groove can hold the part that rubber cushion is extruded distortion.
The utility model belongs to environmental protection technical field.
Background technology
At present, welded construction is adopted in being connected of the base of road, high speed railway sound barrier and column usually, produces tensile stress at joint face, inevitably produces stress in the use and concentrates.And base generally adopts stone bolt directly to be connected with the basis.Owing to be subjected to the travel impact of wind of train or high capacity waggon, can produce flutter in the use, cause the own endurance failure of basis and sound barrier, lose the function of sound barrier.
The utility model content
The utility model provides a kind of base and column is cast in together sound barrier bracing or strutting arrangement, between base and the basis, uses the vibration damping rubber cushion to connect.So that base by the vibration damping rubber cushion with basic be connected stressed after, make groove can hold the part that the vibration damping rubber cushion is extruded distortion, release pressure; Base body also leaves the screwed hole when changing the vibration damping rubber cushion except the installing hole that leaves stone bolt, in order to when changing the vibration damping rubber cushion, can after being screwed into bolt base be propped; The vibration damping rubber cushion all leaves relative coaxial positioning pin-and-hole with base, in order to use alignment pin, string was moving when the restriction rubber cushion was in use stressed.
And use cast steel material directly the sound barrier base to be cast in moulding with column, and do not produce the tensile stress that welding causes, promote mechanical performance of products.Use the vibration damping rubber cushion to connect base and basis, can avoid being rigidly attached to and be subjected to train or high capacity waggon and travel and produce flutter when wind impacts, cause destroying.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the three-dimensional engineering view that base and column is cast in sound barrier bracing or strutting arrangement together;
Fig. 2 is the view of base substructure;
Fig. 3 is the view of base bottom vibration damping rubber cushion.
Among the figure: (1) cast steel column, (2) cast steel base, (3) vibration damping rubber cushion, (4) locating hole, (5) anchor (bolt) hole, (6) rubber cushion distortion release groove, (7) screwed hole.
The specific embodiment
During installation, the anchor (bolt) hole of vibration damping rubber cushion (3) is passed stone bolt, is seated in the installation surface of base, again casting is connected the cast steel column (1) of one and the anchor (bolt) hole (5) above the cast steel base (2) and passes stone bolt, it is fastening to use nut to connect then, squeezes into alignment pin at locating hole (4) at last.
When changing the vibration damping rubber cushion, after backing out anchor bolt nut, extract the alignment pin in the locating hole (4) out, being screwed into four bolts at four screwed holes (7) then withstands on the surface of base, base and basis can be left, prop then, just can change vibration damping rubber cushion (3); Repeat aforesaid installation requirement at last, just can finish the work.
Claims (4)
1. one kind is cast in together sound barrier bracing or strutting arrangement with base and column, it is characterized in that: use the vibration damping rubber cushion to be connected between base and the basis.
2. according to claim 1ly a kind of base and column are cast in together sound barrier bracing or strutting arrangement, it is characterized in that: base lower surface leaves can hold the groove that the vibration damping rubber cushion is extruded crushed element, release pressure.
3. according to claim 1ly a kind of base and column are cast in together sound barrier bracing or strutting arrangement, it is characterized in that: base body is except the installing hole that leaves stone bolt, also leave the screwed hole when changing the vibration damping rubber cushion, so that when changing the vibration damping rubber cushion, can after being screwed into bolt, base be propped.
4. according to claim 1ly a kind of base and column are cast in together sound barrier bracing or strutting arrangement, it is characterized in that: the vibration damping rubber cushion all leaves relative coaxial positioning pin-and-hole with base, in order to use alignment pin, string was moving when the restriction rubber cushion was in use stressed.
