Description

Technical Field

[0001] This application relates to the field of steel structure buildings, and in particular to a steel structure factory building. Background Art

[0002] A steel structure factory building refers to a factory building whose main load-bearing components are made of steel. It usually includes a steel structure frame, wall panels installed on the outer side of the steel structure frame, and cover plates covering the top of the steel structure frame. Steel structure factory buildings are widely selected because of their light structural quality, high strength, and short construction period.

[0003] However, in the existing steel structure factory buildings, the steel materials between adjacent steel structure frames are usually connected by welding or bolts. Although this connection method can achieve fixed connection between two steel materials, it often takes a lot of time during implementation. For example, during welding, welders need to carry tools to weld the connection between the two steel materials. When connecting by bolts, it takes extra time to tighten and check numerous bolts, resulting in too long construction time for the steel structure frame and low efficiency. Summary of the Invention

[0004] In order to improve the construction efficiency of the steel structure frame, this application provides a steel structure factory building.

[0005] The steel structure factory building provided by this application adopts the following technical solutions:

[0006] It includes a steel structure frame, multiple wall panels installed outside the steel structure frame, and multiple cover plates installed on the top of the steel structure frame. The steel structure frame includes multiple vertical beams, multiple horizontal beams, and multiple connectors for connecting the horizontal beams and the vertical beams. The connector includes a vertical sleeve and multiple horizontal sleeves. Each horizontal sleeve is vertically connected to the outer side walls of the vertical sleeve. The vertical beam is inserted into the corresponding vertical sleeve. The vertical sleeve is provided with perforations, and the outer part of the vertical beam corresponding to the perforations is provided with insertion holes. The horizontal beam is inserted into the corresponding horizontal sleeve. One end of the horizontal beam located inside the horizontal sleeve is provided with a connection head. The connection head passes through the perforation and the insertion hole and is partially located inside the vertical beam. An anti-disengagement member is provided at the end of the vertical sleeve away from the vertical beam. The anti-disengagement member is used to prevent the connection head from disengaging from the inside of the vertical beam.

[0007] By adopting the above technical solution, when it is necessary to build a steel structure framework, first insert the vertical beam into the vertical sleeve of a connecting piece, and then insert the cross beam into the transverse sleeve in turn. The connecting head on the cross beam passes through the through hole on the vertical sleeve and the jack on the vertical beam and inserts into and partially located inside the vertical beam, which makes the quantity not easily fall out of the quantity sleeve. After the vertical beam is fixed, put the anti-disengagement part into the vertical sleeve from the end far away from the cross beam, and the anti-disengagement part is inserted into the connecting head located inside the vertical beam, so that the connecting head on the cross beam will not easily fall out of the anti-disengagement part, and further the cross beam will not fall out of the transverse sleeve. During the whole process, the connection between the cross beam and the vertical beam can be realized without welding or bolts, reducing the time for welding or tightening bolts one by one at the connection between the cross beam and the vertical beam, and achieving the effect of increasing the construction speed of the steel structure framework.

[0008] Optionally, a connecting groove is provided on the part of the connecting head located inside the vertical beam. The anti-disengagement part includes an anti-disengagement portion, a connecting portion and a mounting portion. One end of the connecting portion is connected to the anti-disengagement portion, and the other end of the connecting portion is connected to the mounting portion. The anti-disengagement portion can slide inside the vertical beam. A clamping groove adapted to the connecting groove is provided on the outer wall of the anti-disengagement portion, and the clamping groove is inserted and matched with the connecting groove. The mounting portion can be connected to the end of the vertical sleeve far away from the vertical beam.

[0009] By adopting the above technical solution, the anti-disengagement part includes an anti-disengagement portion, a connecting portion and a mounting portion. Clamping grooves are respectively provided on the outer side wall of the anti-disengagement portion. When the anti-disengagement portion slides from the end of the vertical sleeve far away from the vertical beam into the vertical beam, the clamping groove on the anti-disengagement portion is inserted into the connecting head located inside the vertical beam from the up and down direction, and the connecting portion enables the position of the limiting portion in the vertical beam to be adjusted in time when the limiting portion slides in the vertical beam. The mounting portion is connected to the end of the vertical sleeve far away from the vertical beam, so that the limiting portion and the mounting portion will not fall out of the inside of the vertical beam.

[0010] Optionally, a plurality of purlins are provided between two parallel cross beams. The plurality of purlins are spaced along the length direction of the cross beam. The two ends of each purlin are respectively embedded in the two cross beams. A cover plate is laid on the purlin, and the cover plate is connected to the cross beam.

[0011] By adopting the above technical solution, the two ends of each purlin are respectively embedded in the two cross beams, so that the connection between the purlin and the cross beam can also be realized without welding or bolts, saving the connection time. And the cover plate is laid on the purlin and connected to the cross beam, so that the embedding between the purlin and the cross beam will not easily fail.

[0012] Optionally, a connecting plate is provided between two adjacent transverse sleeves on the connecting piece. The connecting plate is vertically fixed between the two adjacent transverse sleeves respectively. A connecting beam is provided on the connecting plates of the two connecting pieces on the diagonal line. The connecting beam is connected to the connecting plate by means of bolt connection. The connecting beam is located below the purlin.

[0013] By adopting the above technical solution, the connecting beam is located on the diagonal line, ensuring the connection stability between the cross beam and the vertical beam. At the same time, since the connecting beam is below the purlin, it can support the purlin, so that the purlin will not break easily when bearing the cover plate.

[0014] Optionally, the wall panel is provided with a plug-in portion, which can be plugged and matched with the corresponding transverse sleeve. The cross-section formed by combining the plug-in portions on two adjacent wall panels is adapted to the inner wall contour of the cross beam sleeve.

[0015] By adopting the above technical solution, the wall panel is provided with a plug-in portion, and the cross-section formed by combining the plug-in portions on two adjacent wall panels is adapted to the inner wall contour of the cross beam sleeve, so that the plug-in portions close to each other on two adjacent wall panels can be plugged into the same cross beam sleeve. This makes the connection between two adjacent wall panels tighter and the gap smaller. At the same time, it is also convenient for the wall panels to be installed tightly and orderly along the direction of the cross beam.

[0016] Optionally, the inner wall of the transverse sleeve is provided with a clamping groove, and the outer wall of the plug-in portion is provided with a receiving groove, a clamping block and a spring. One end of the clamping block close to the transverse sleeve is hinged to the outer wall of the plug-in portion. The receiving groove is located on the plug-in portion. One end of the spring is connected to the end of the clamping block far from the hinge axis, and the other end of the spring is connected in the receiving groove. The clamping block and the clamping groove are connected by clamping.

[0017] By adopting the above technical solution, when the plug-in portion on the wall panel is plugged into the transverse sleeve, when the clamping block on the plug-in portion moves to the clamping groove in the transverse sleeve, the clamping block will be ejected under the action of the spring, so that the end of the clamping block far from the hinge axis is clamped with the clamping groove, thus preventing the plug-in portion from easily disengaging from the cross beam sleeve.

[0018] Optionally, anti-disengagement grooves are provided on both sides of the wall panel, and anti-disengagement beams are arranged in the anti-disengagement grooves by plugging and matching. The cross-section of the anti-disengagement beam is adapted to the contour formed by combining the anti-disengagement grooves on two adjacent wall panels.

[0019] By adopting the above technical solution, the cross-section of the anti-disengagement beam is adapted to the contour formed by combining the anti-disengagement grooves on two adjacent wall panels, making the connection between two adjacent wall panels tighter. Thus, two adjacent wall panels can be pre-assembled before being connected to the transverse sleeve to improve the installation efficiency of the wall panels.

[0020] Optionally, the anti-disengagement beam is provided with a grouting hole, and an out-grouting hole is provided on the side of the anti-disengagement beam close to the wall panel. The grouting hole is communicated with the out-grouting hole.

[0021] By adopting the above technical solution, after the wall panel is installed, cement mortar is poured into the grouting hole, and the cement mortar will gush out from the slurry outlet hole on the anti-disengagement beam, and then adhere to the side wall of the anti-disengagement groove and the side wall of the anti-disengagement beam. After the cement mortar solidifies, the connection tightness between the anti-disengagement beam and the anti-disengagement groove is further increased.

[0022] In summary, the present application includes at least the following beneficial technical effects:

[0023] 1. By setting the connecting piece and the anti-disengagement piece, the connection between the cross beam and the vertical beam constituting the steel structure frame does not need to be connected by welding or bolt connection, saving the time spent on welding or bolt connection, and achieving the effect of improving the assembly efficiency of the steel structure frame;

[0024] 2. By injecting cement mortar into the grouting hole on the anti-disengagement beam, and the cement mortar can flow out from the slurry outlet hole, the gap between the anti-disengagement beam and the anti-disengagement groove can be filled with cement mortar, and then the effect of increasing the connection tightness between the anti-disengagement beam and the anti-disengagement groove is achieved; Description of the Drawings

[0032] The following further describes the present application in conjunction with the attached Figure 1 -., 6 with more details

[0033] An embodiment of the present application discloses a steel structure factory building, referring to Figure 1 , including a steel structure frame 1, multiple wall panels 2 and multiple cover plates 3. Among them, both the wall panel 2 and the cover plate 3 are prefabricated parts. Multiple wall panels 2 are all installed on the outer side of the steel structure frame 1, and multiple cover plates 3 cover the top of the steel structure frame 1

[0034] Referring to Figure 2 , Figure 3 and Figure 4 , the steel structure frame 1 includes multiple vertical beams 4, multiple cross beams 5 and multiple connectors 6 for realizing the connection between the vertical beams 4 and the cross beams 5. The vertical beam 4 is a square tube with both ends not closed, and the cross beam 5 is a square tube with both ends closed. Among them, one connector 6 includes a vertical sleeve 7 and multiple horizontal sleeves 8. Multiple horizontal sleeves 8 are respectively installed on different outer side walls of the vertical sleeve 7 and are all connected to the vertical sleeve 7 by welding. The vertical beam 4 can be inserted into the vertical sleeve 7 by means of insertion and cooperation. A perforation 9 is provided on the outer side wall of the vertical sleeve 7, and a socket 10 is provided at the position of the vertical beam 4 corresponding to the perforation 9. The cross beam 5 is inserted into the corresponding horizontal sleeve 8. A connector head 11 is provided at the end of the cross beam 5 located in the horizontal sleeve 8. The connector head 11 is perpendicular to the horizontal sleeve 8. When the cross beam 5 is inserted into the horizontal sleeve 8, the connector head 11 passes through the perforation 9 on the vertical sleeve 7 and the socket 10 on the vertical beam 4, and a part of the connector head 11 is located inside the vertical beam 4, which makes the vertical beam 4 not easily come out of the vertical sleeve 7

[0035] At one end of the vertical sleeve 7 far from the vertical beam 4, an anti - detachment member 12 is provided. The anti - detachment member 12 includes an anti - detachment part 13, a connecting part 14 and a mounting part 15. One end of the connecting part 14 is connected to the anti - detachment part 13, and the other end of the connecting part 14 is connected to the mounting part 15. The anti - detachment part 13 can slide along the length direction of the vertical beam 4 within the vertical beam 4. A connecting groove 29 surrounding the outer wall of the connecting head 11 is provided on the part of the connecting head 11 located within the vertical beam 4, and a clamping groove 16 adapted to the connecting groove 29 on the connecting head 11 is provided on the outer wall of the anti - detachment part 13. When the anti - detachment part 13 slides within the vertical beam 4 along the length direction of the vertical beam 4, the clamping groove 16 on the outer wall of the anti - detachment part 13 can be clamped with the connecting groove 29 of the connecting head 11. At this time, the surface of the mounting part 15 close to the connecting part 14 just abuts against the end face of the vertical sleeve 7 far from the vertical beam 4 and is connected to the vertical sleeve 7 by means of bolt connection. Under the action of the anti - detachment part 13, the part of the connecting head 11 located within the vertical beam 4 will not easily come out of the vertical beam 4, and thus the cross - beam 5 will not easily come out of the horizontal sleeve 8 either.

[0036] Refer to Figure 2 and Figure 3 As shown in and, multiple purlins 17 are arranged between two parallel cross - beams 5. A plurality of placing grooves for placing the purlins 17 are arranged at intervals along the length direction on the two cross - beams 5 where the purlins 17 are installed, and the ends of the purlins 17 can be placed in the placing grooves. The cover plate 3 is laid above the purlins 17. The purlins 17 are used to support the cover plate 3. At the same time, the two ends in the length direction of the cover plate 3 are respectively connected to the cross - beam 5 by bolts, which makes the purlins 17 not come out of the cross - beam 5 when the cover plate 3 is connected to the cross - beam 5.

[0037] Furthermore, a connecting plate 18 is provided between two adjacent vertical sleeves 7 on the connecting piece 6. The connecting plate 18 is fixedly connected to the two horizontal sleeves 8 respectively. A connecting beam 19 is provided between two diagonal connecting plates 18 at the top of the vertical beam 4. The connecting beam 19 is fixed to the connecting plate 18 by means of bolt connection, and the connecting beam 19 is installed below the purlins 17 to play a certain supporting role for the purlins 17, so as to reduce the risk that the purlins 17 fail due to the excessive weight of the snow accumulated on the cover plate 3 in heavy snow weather.

[0038] Refer to Figure 2 、 Figure 3 and Figure 5, and for the convenience of installing the wall panel 2, a plug-in part 20 is provided on the wall panel 2, and the cross-section after combination between the plug-in parts 20 on two adjacent wall panels 2 is adapted to the contour of the inner wall of the transverse sleeve 8, which makes it not easy for the plug-in parts 20 on two adjacent wall panels 2 to separate after being respectively inserted into the transverse sleeve 8. And in order to prevent the plug-in part 20 on the wall panel 2 from being disengaged from the transverse sleeve 8, a clamping groove 21 is provided on the inner wall of the transverse sleeve 8, and a receiving groove 24, a clamping block 22 and a spring 23 are provided on the outer wall of the plug-in part 20. Both the clamping block 22 and the spring 23 are arranged in the receiving groove 24. One end of the clamping block 22 close to the transverse sleeve 8 is hinged to the plug-in part 20, and one end of the spring 23 is connected to the end of the clamping block 22 far from the hinge axis, and the other end of the spring 23 is connected in the receiving groove 24. This makes the clamping block 22 always located in the receiving groove 24 during the process of the plug-in part 20 entering the transverse sleeve 8. And as the plug-in part 20 moves in the transverse sleeve, when the plug-in part 20 moves to the clamping groove 21 in the transverse sleeve 8, the end of the clamping block 22 far from the hinge axis is ejected under the action of the spring 23, so that the clamping block 22 is clamped in the clamping groove 21, and further makes it not easy for the wall panel 2 to be disengaged from the transverse sleeve 8 after being connected to the transverse sleeve 8.

[0039] Refer to Figure 2 , Figure 5 and Figure 6 , further, in order to save the time for installing the wall panel 2, two wall panels 2 can be pre-installed first. Anti-disengagement grooves 25 are respectively provided on both sides of the wall panel 2 in the length direction. The anti-disengagement grooves 25 can be dovetail grooves or C-shaped sliding grooves. An anti-disengagement beam 26 is provided in the anti-disengagement grooves 25. The cross-section of the anti-disengagement beam 26 is adapted to the cross-section formed by the two anti-disengagement grooves 25 when the surfaces of two adjacent wall panels 2 provided with the anti-disengagement grooves 25 are tightly abutted against each other. This makes the anti-disengagement beam 26 can be inserted between two adjacent wall panels 2 to realize the assembly between the two wall panels 2, and further enables the wall panel 2 to be pre-installed before being installed on the transverse sleeve 8 to save the installation time of the wall panel 2.

[0040] Furthermore, slurry outlet holes 27 are respectively provided on both sides of the anti-disengagement beam 26 in the length direction, and a slurry inlet hole 28 communicating with the slurry outlet holes 27 is provided on the top of the anti-disengagement beam 26. This makes it possible to pour cement mortar etc. into the slurry inlet hole 28 when the anti-disengagement beam 26 is installed between two adjacent wall panels 2. The cement mortar flows out from the slurry outlet holes 27 and gradually fills the gap between the anti-disengagement beam 26 and the anti-disengagement grooves 25. On the one hand, it makes the abutment between the anti-disengagement beam 26 and the anti-disengagement grooves 25 closer, and on the other hand, it also makes the connection between the anti-disengagement beam 26 and the anti-disengagement grooves 25 more firm, so that the anti-disengagement beam 26 will not fall out of the anti-disengagement grooves 25 vertically under the action of gravity.

[0041] The implementation principle of the embodiments of this application is as follows: First, insert the vertical beam 4 into the vertical sleeve 7, and then insert the cross beams 5 one by one into the corresponding horizontal sleeves, so that the connecting heads 11 at the ends of the cross beams 5 pass through the through holes 9 on the vertical sleeve 7 and the jack holes 10 on the vertical beam 4, ensuring that the vertical beam 4 does not fall out of the vertical sleeve 7. Then, place the anti-disengagement member 12 from the end of the vertical sleeve away from the vertical beam 4, so that the card slots 16 on the anti-disengagement part 13 are engaged with the connecting grooves 29 on the connecting head 11 in a top-down manner within the vertical beam 4, thereby preventing the cross beam 5 from easily falling out of the horizontal sleeve 8. After that, fix the installation part 15 on the end face of the vertical sleeve 7, and repeat this process until the connection between the cross beams 5 and the vertical beams 4 in the entire steel structure frame 1 is achieved.

[0042] Then, install the connecting beam 19 on the connecting plates 18 of the two connecting members 6 on the diagonal, lay the purlins 17 along the length direction of the cross beam 5, and lay the cover plate 3 above the purlins 17 and fix the cover plate 3 to the cross beam 5 to prevent the purlins 17 from falling out of the cross beam 5.

[0043] After that, pre-assemble the two wall panels 2 on the same side of the steel structure frame 1 through the anti-disengagement beam 26, and install the two wall panels 2 on the assembled steel structure frame 1 through the plug-in fit between the plug-in parts 20 and the horizontal sleeves 8.

[0044] Finally, pour cement mortar into the grouting hole 28. The cement mortar flows out from the slurry outlet hole. Stop grouting when the cement mortar seeps out from the gap between the anti-disengagement beam 26 and the anti-disengagement groove 25, wait for the cement mortar to solidify, and then install the cover plate 3.

[0045] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
