Abstract
A kind of built-in fitting guaranteeing flatness, belongs to structural engineering technical field.Including top board, vertically to stiffener；The reinforcing bar on plant bottom case basis pass through vertical on stiffener with elliptical aperture, be vertically welded to one entirety of composition on the bottom surface of top board to stiffener, on the basis of being embedded into plant bottom case.Advantage is：Effectively ensure that the flatness of large scale built-in fitting it is ensured that main equipment installation accuracy reaches design requirement.
Description
Technical field
This utility model belongs to structural engineering technical field, particularly to a kind of built-in fitting guaranteeing flatness.Especially
It is related to still can ensure that the built-in fitting of flatness very little under a kind of large scale steel plate.
Background technology
In some industry and civil buildings, generally there are some main equipments larger due to the vibration of itself, so supporting leg
Very long and very high to the installation requirement precision of earth plate, at this moment just require the flatness of built-in fitting in equipment Foundations to be in non-
Often little level.
Traditional built-in fitting, is all that steel plate is formed with reinforcement welding, when plate size is larger, is led due to due to deadweight
Cause built-in fitting flatness very big.
Content of the invention
The purpose of this utility model is to provide a kind of built-in fitting guaranteeing flatness, solves traditional built-in fitting size relatively
The built-in fitting flatness that causes because of reasons such as deadweight and construction errors when big problem bigger than normal.
A kind of built-in fitting guaranteeing flatness, including top board 1 with vertically to stiffener 2；The reinforcing bar on plant bottom case basis is worn
Cross vertically on stiffener 2 with elliptical aperture, be vertically welded on the bottom surface of top board 1 one entirety of composition to stiffener 2, in advance
On the basis of burying plant bottom case.
As the top surface of built-in fitting, its thickness is more than 12mm to top board 1, vertically will not be sent out to during stiffener 2 with guaranteeing to weld
Change shape；
The elliptical aperture that spacing is 100mm～250mm is vertically carried on stiffener 2, this hole is used in plant bottom case basis
The passing through of reinforcing bar；
The vertical center being welded to top board 1 to stiffener 2, organizes the main body of T-shaped built-in fitting；
Because the presence of elliptical aperture is it can be ensured that the reinforcing bar on plant bottom case basis will not be cut because of the presence of built-in fitting
Disconnected, also enhance the withdrawal resistance of built-in fitting simultaneously；
Due to the vertical presence to stiffener 2, built-in fitting is all very big in the cross sectional moment of inertia of level and vertical direction, thus
Even if built-in fitting size is very big, also can guarantee that flatness is very little.
The utility model has the advantage of：Effectively ensure that the flatness of large scale built-in fitting it is ensured that main equipment is installed
Precision reaches design requirement.

Specific embodiment
Embodiment 1
This utility model includes top board 1, vertically to stiffener 2；The reinforcing bar on plant bottom case basis passes through vertically to stiffener 2
On with elliptical aperture, be vertically welded on the bottom surface of top board 1 one entirety of composition to stiffener 2, be embedded into plant bottom case base
On plinth.
Top board 1 as the top surface of built-in fitting, its thickness 20mm, with guarantee welding vertically will not become to during stiffener 2
Shape；
Vertical the elliptical aperture that spacing is 150mm is carried on stiffener 2, this hole is used for the logical of reinforcing bar in plant bottom case basis
Cross；
The vertical center being welded to top board 1 to stiffener 2, organizes the main body of T-shaped built-in fitting；
Because the presence of elliptical aperture is it can be ensured that the reinforcing bar on plant bottom case basis will not be cut because of the presence of built-in fitting
Disconnected, also enhance the withdrawal resistance of built-in fitting simultaneously；
Due to the vertical presence to stiffener 2, by cross sectional moment of inertia computing formula it is known that this novel embedded part exists
The cross sectional moment of inertia of level and vertical direction is all very big, even if thus built-in fitting size is very big, also can guarantee that flatness is very little.
