Detailed Description
The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.
As shown in fig. 1-10, the assembled multi-layer steel structure factory building frame structurally comprises a steel roof truss 10, outer wall upright posts 11, outer wall cross bars 12, steel purlines 13 and floor steel beams 14, further comprises upright post units 1, screw block units 2 which are arranged on the upright post units 1 and are used for connecting steel roof truss bottom plates 10a, and supporting block units 3 which are arranged on the upright post units 1 and are used for supporting the floor steel beams 14.
In this embodiment, the frame does not include structures such as floors a, wall panels, windows, and roof panels. The steel roof truss 10 is prefabricated in a factory, the outer wall upright posts 11 and the outer wall cross bars 12 are fixedly connected in advance in a small range, and are assembled and fixed in a large area after being pulled to a factory construction site from the factory.
In addition, the two ends of the floor slab steel beam 14 are welded or screwed with the outer wall upright posts 11, the screwed block units 2 are used for fixedly connecting the upright post units 1 and the steel roof truss bottom plate 10a, the supporting block units 3 are used for at least supporting the floor slab steel beam 14, and finally, the floor a is paved on the floor slab steel beam 14, so that the subsequent factory building detail installation can be smoothly carried out.
The column unit 1 comprises a I-steel 101 and a mounting hole 102 arranged on the I-steel 101.
In this embodiment, if the column unit 1 uses angle steel or C-steel, the strength of the column unit is not as high as that of the i-steel 101, so that it is ensured that the i-steel 101 can support more than one floor structure.
Furthermore, the screw block unit 2 connects the i-beam 101 and the entire steel roof truss 10 precisely through the mounting hole 102.
In the prior art, the steel roof truss 10 is most commonly a light steel roof truss, and the steel roof truss bottom plate 10a is generally angle steel or C-shaped steel.
The column unit 1 further comprises a supporting base plate 103 arranged on the lower end face of the I-steel 101.
In this embodiment, the supporting base 103 is used to directly press on the ground, and is welded or screwed with the i-beam 101.
The screw block unit 2 includes an inner inverted L-shaped block 201 provided on the lower surface of the steel roof truss bottom plate 10a and the inner side surface of the middle portion of the i-beam 101, and first perforations 202 provided on the top plate and the side plates of the inner inverted L-shaped block 201.
In this embodiment, the 2 inner inverted L-shaped blocks 201 are respectively located at two sides of the "i-shaped" inner portion, and are used for connecting the steel roof truss bottom plate 10a after the bolts and nuts are installed in the first through holes 202 on the top plate, and are used for connecting the i-steel 101 after the bolts and nuts are installed in the first through holes 202 on the side plate.
The top plate of the inner inverted L-shaped block 201 is provided with 1 first through hole 202.
In this embodiment, the number of the first through holes 202 on the side plate is not particularly limited, and the first through holes may correspond to the mounting holes 102 one by one.
However, the first through hole 202 on the top plate needs to be provided with a bolt and a nut, and the bolt and the nut need to avoid the vertical side plate structure of the angle steel or the C-shaped steel of the steel roof truss bottom plate 10a, so that the first through hole 202 cannot be provided too much and needs to be positioned as far inward as possible, that is, as shown in fig. 2.
The screw block unit 2 further includes an outer inverted L-shaped block 203 provided on the lower surface of the steel roof truss bottom plate 10a and the outer side surface of the i-beam 101, and second perforations 204 provided on the top plate and the side plates of the outer inverted L-shaped block 203.
In this embodiment, the number of the outer inverted L-shaped blocks 203 is also 2, and the second through holes 204 on the top plate are also connected to the steel roof truss bottom plate 10a, and the second through holes 204 on the side plates are also connected to the i-steel 101. The outer inverted L-shaped block 203 is larger in size than the inner inverted L-shaped block 201.
In addition, the mounting holes 102 may be formed in the middle plate and the side plates of the i-steel 101, so that the side inverted L-shaped blocks 203 and the inner inverted L-shaped blocks 201 may be screwed smoothly.
However, it is also possible to provide the mounting hole 102 only in the intermediate plate, and in this case, the second through hole 204, that is, the outer side surface of the i-beam 101 may be welded with a steel column and then supported.
The lateral spacing of the second perforations 204 on the side plate of the outer inverted L-shaped block 203 is greater than the lateral spacing of the second perforations 204 on the top plate of the outer inverted L-shaped block 203.
In this embodiment, the "side plate bolt" on the outer inverted L-shaped block 203 needs to avoid the inner inverted L-shaped block 201 during installation, so the second through hole 204 on the side plate needs to be properly spaced apart from each other in a lateral direction, and needs to be properly opened side by side.
The supporting block unit 3 comprises an outer U-shaped block 301 which is arranged on the I-steel 101 in a clamping way and is used for simultaneously supporting two floor slab steel beams 14.
In this embodiment, the outer U-shaped block 301 and the i-steel 101 may be screwed or welded. The word "outer" refers to that the i-beam 101 is clamped into the U-shaped block, 2 side plates of the outer U-shaped block 301 are used for supporting one floor steel beam 14, and a part of side plates and an intermediate plate are used for supporting the other floor steel beam 14.
The support block unit 3 further includes a protruding support block 302 provided on the outer side surface of the middle portion of the outer U-shaped block 301.
In this embodiment, the protruding supporting blocks 302 serve to supplement the middle plate of the outer U-shaped block 301, equivalently increasing the thickness of the middle plate, so that a total of 2 floor beams 14 on both sides of the i-beam 101 can be effectively supported.
In addition, the support block unit 3 and the floor slab steel beam 14 may be welded or screwed.
And 2-3 supporting block units 3 are arranged on each upright column unit 1.
In this embodiment, the multi-layer steel structure factory building is set to 3 or 4 layers, otherwise, the post unit 1 may have problems of overload and self-deformation. At this time, the number of the corresponding support block units 3 is 2 or 3.
The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
