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 through vertical on stiffener with elliptical aperture, vertically be welded on the bottom surface of top board constitute an entirety, on the basis of being embedded into plant bottom case to stiffener.Advantage is: effectively ensure that the flatness of large scale built-in fitting, it is ensured that main equipment installation accuracy reaches to design requirement.

Description

A kind of built-in fitting guaranteeing flatness
Technical field
The invention belongs to structural engineering technical field, particularly to a kind of built-in fitting guaranteeing flatness.Especially relate to And still can ensure that, under a kind of large scale steel plate, the built-in fitting that flatness is the least.
Background technology
In some industry and civil buildings, generally there are some main equipments relatively big due to the vibration of self, so supporting leg The longest and the highest to the installation requirement precision of earth plate, the most just require that in equipment Foundations, the flatness of built-in fitting is in non- The least level.
Traditional built-in fitting, is all that steel plate forms with reinforcement welding, when plate size is bigger, owing to the reason of deadweight is led Cause built-in fitting flatness the biggest.
Summary of the invention
It is an object of the invention to provide a kind of built-in fitting guaranteeing flatness, solve tradition built-in fitting size bigger time The problem that the built-in fitting flatness that causes because of deadweight and the reason such as construction error is 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 vertical on stiffener 2 with elliptical aperture, be vertically welded on the bottom surface of top board 1 constitute an entirety to stiffener 2, in advance On the basis of burying plant bottom case.
Top board 1 is as the end face of built-in fitting, and its thickness is more than 12mm, with guarantee welding vertically to stiffener 2 time will not send out Change shape;
Vertically with the elliptical aperture that spacing is 100mm~250mm on stiffener 2, this hole is in plant bottom case basis Passing through of reinforcing bar;
The vertical center being welded to top board 1 to stiffener 2, the main body of composition T-shaped built-in fitting;
Existence due to elliptical aperture, it can be ensured that the reinforcing bar on plant bottom case basis will not be cut because of the existence of built-in fitting Disconnected, also enhance the withdrawal resistance of built-in fitting simultaneously;
Owing to vertically to the existence of stiffener 2, built-in fitting is the biggest at 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 the least.
It is an advantage of the current invention that: effectively ensure that the flatness of large scale built-in fitting, it is ensured that main equipment installation accuracy Reach to design requirement.

Detailed description of the invention
Embodiment 1
The present invention includes top board 1, vertically to stiffener 2;The reinforcing bar on plant bottom case basis carries on stiffener 2 through vertical The elliptical aperture, is vertically welded to stiffener 2 on the bottom surface of top board 1 constitute an entirety, on the basis of being embedded into plant bottom case.
Top board 1 as the end face of built-in fitting, its thickness 20mm, with guarantee welding vertically to stiffener 2 time will not become Shape;
Vertical is the elliptical aperture of 150mm with spacing on stiffener 2, this hole reinforcing bar logical in plant bottom case basis Cross;
The vertical center being welded to top board 1 to stiffener 2, the main body of composition T-shaped built-in fitting;
Existence due to elliptical aperture, it can be ensured that the reinforcing bar on plant bottom case basis will not be cut because of the existence of built-in fitting Disconnected, also enhance the withdrawal resistance of built-in fitting simultaneously;
Due to vertical to the existence of 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 the biggest, even if thus built-in fitting size is very big, also can guarantee that flatness is the least.
