Abstract
The utility model discloses a middle beam which is characterized in that the middle beam comprises a body, an upper surface, two frame ribs in a shape of Chinese character 'ao' (meaning 'concave') and two groove type frame ribs, wherein the upper surface is positioned on the body; fixing holes are arranged on the frame ribs in the shape of Chinese character 'ao' and the groove type frame ribs; the two frame ribs in the shape of Chinese character 'ao' are symmetrically arranged and are longitudinally and fixedly connected at the upper parts of the side surfaces of the body; the two groove type frame ribs are symmetrically arranged and are longitudinally and fixedly connected at the lower parts of the side surfaces of the body and under the frame ribs in the shape of Chinese character 'ao'; the lower parts of the frame ribs in the shape of Chinese character 'ao' are fixedly connected with the groove type frame ribs. The middle beam can be dismantled before a main support structure, therefore, the operation is safe and simple, the cycle of turnover is shortened, the middle beam can be reused, and the cost is saved.
Description
Technical field
The utility model relates to a kind of central sill, is mainly used in building field.
Background technology
In existing field of engineering technology, in building field, central sill is the indispensable part of supporting construction, and in the practice, using more is that steel is stupefied and wooden stupefied, supports firmly inadequately, and remove can only be with form removal the time, and the dismounting hazardous, turn around time is long.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of central sill is characterized in that: comprise body, upper surface, two matrix frame ribs and two grooved frame ribs; Said upper surface is positioned at the body top; All be provided with fixing hole on said matrix frame rib and the grooved frame rib; Said two matrix frame ribs are symmetrical set, and vertically are fixed in the top of body side; Said two grooved frame ribs are symmetrical set, and vertically be fixed in the body side bottom, matrix frame rib below; The top of the bottom of matrix frame rib and grooved frame rib is affixed.
During use, grooved frame rib adds steel plate (being provided with fixing hole) with main brace footstock grooved frame rib and is fixedly connected (as passing through fixator pins), and matrix frame rib is connected (as passing through fixator pins) with steel form frame rib, thereby sets up firm, reliable supporting construction.The comparable main brace structure of central sill is dismantled in advance, and is safe and simple, and turn around time is short, and is reusable, practices thrift cost.
Description of drawings
Fig. 1 is the structural representation of the utility model central sill;
Fig. 2 is the cross-sectional view of the central sill of Fig. 1;
Fig. 3 is the plan structure sketch map of the central sill of Fig. 1.
The specific embodiment
Below in conjunction with the specific embodiment introduction:
Shown in Figure 1-3, the beam includes a body 1, two ribs 2 and two concave groove border frame ribs 3, an upper surface 4; body 1 is "Shang" type, two symmetrical concave border ribs 2 settings, and longitudinally welded to the upper side of the body; two slotted frame ribs 3 are symmetrically disposed, and longitudinally welded to the lower side of the body, the lower concave border rib 2; concave lower border of the ribs 2 and the groove border rib 3 upper welding.Upper surface 4 is welded on above the body, is tiled on two matrix frame ribs 2.Establish the fixing hole 21 that is used to connect steel form on the matrix frame rib 2, grooved frame rib 3 is provided with the fixing hole 31 that is used to connect the main brace footstock.
During use, grooved frame rib 3 adds steel plate with main brace footstock grooved frame rib and is fixedly connected (as passing through fixator pins), and matrix frame rib 2 is connected (as passing through fixator pins) with steel form frame rib, thereby sets up firm, reliable supporting construction.Body 1, two matrix frame ribs 2 and two grooved frame ribs 3 are to adopt 9235 steel plates to be shaped through the cold rolling welding processing of punching press, and are surperficial through antirust processing.
