Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a roof beam support column foot support and a construction method thereof. Background Art

[0002] During building construction, when erecting steel structures above the roof, it is usually necessary to first construct beam support columns on the supporting steel beams of the roof, and then construct the steel structure above the roof to support the steel structure components.

[0003] In the traditional construction method, the column base of the beam support column is usually welded to the supporting steel beam of the roof in advance, and then the roof is constructed above the supporting steel beam of the roof; after the roof construction is completed, the steel structure is constructed above the roof through the beam support column.

[0004] However, after the column base of the beam support column is constructed by pre-welding it to the supporting steel beam of the roof, the supporting beam is subjected to a large force, which makes it easy to become unstable and lose its bearing capacity, resulting in construction accidents. At the same time, the beam support column needs to be pre-constructed on the supporting steel beam of the roof, which will to a certain extent limit the flexibility of subsequent steel structure construction and bring inconvenience to the construction of the steel structure. Summary of the invention

[0005] The present application provides a roof beam support column foot support and a construction method thereof, which can facilitate the construction of beam support columns and subsequent steel structures, and can effectively reduce the force acting on the support column beam and the probability of its being damaged.

[0010] Optionally, the first support member is in a contracted shape in a direction away from the first connecting plate.

[0011] By adopting the above technical solution, it is possible to facilitate welding of the first support member on the supporting steel beam, thereby reducing the difficulty of construction; at the same time, it is possible to reduce the impact of the connection of the lower support to the supporting steel beam on subsequent roof construction.

[0012] Optionally, the upper support includes a second connecting plate, a second supporting member and a third connecting plate; Two ends of the second support member are fixedly connected to the second connecting plate and the third connecting plate respectively, the third connecting plate is used to be fixedly connected to the column, and the second connecting plate and the third connecting plate are parallel to each other; After the upper support is connected to the lower support, the first connecting plate is in contact with the second connecting plate and abuts against each other, and the third connecting plate is in a horizontal state.

[0013] By adopting the above technical solution, the upper support can facilitate the connection between the column and the lower support, effectively reducing the construction difficulty of forming the connection between the column and the lower support.

[0014] Optionally, it further comprises a plurality of connection components, and the upper support and the lower support are detachably connected via the plurality of connection components; The connecting assembly includes a screw, a washer and a nut; The first connecting plate is provided with a plurality of through holes for the tail of the screw to pass through, and the second connecting plate is provided with a plurality of clearance grooves for the tail of the screw to pass through; the gasket is provided with a clearance hole for the tail of the screw to pass through, and the nut can cooperate with the tail thread of the screw; When the upper support is connected to the lower support, the tail of the screw passes through the through hole and the clearance groove, and the head of the screw contacts and abuts against the first connecting plate; the gasket is fitted with the tail of the screw through the clearance hole, and contacts and abuts against the second connecting plate; the nut is threadedly fitted with the tail of the screw, and contacts and abuts against the gasket.

[0015] By adopting the above technical solution, the process of achieving detachable connection between the upper support and the lower support can be made more convenient and quicker, and at the same time, the column can have a certain flexibility in position adjustment during installation above the lower support, thereby making the subsequent construction process of the steel structure more convenient.

[0016] Optionally, the connecting assembly includes two nuts in total; when the upper support is connected to the lower support, the two nuts cooperate with the tail thread of the screw, one nut contacts and abuts against the gasket, and the two nuts contact and abut against each other.

[0017] By adopting the above technical solution, the stability of the connection component that connects and fixes the upper support and the lower support can be effectively improved, and the connection strength between the two can be improved, thereby effectively improving the structural stability of the subsequent steel structure after construction.

[0018] Optionally, the connection assembly further comprises an elastic sealing member, and a clamping groove for clamping and installing the sealing member is provided on one side of the gasket; after the nut is matched with the tail thread of the screw rod, the nut can cover the opening of the clamping groove; The clamping groove includes a first groove and a second groove, and the first groove is located on a side of the second groove close to the clearance hole; When one end of the seal is snap-fitted with the first groove or the second groove, the other end of the seal is located outside the snap-fit ​​groove; when the nut is engaged with the tail thread of the screw and contacts and abuts against the gasket, the seal is squeezed and bent, and the other end is snapped into the second groove or the first groove; so that the seal completely fills the snap-fit ​​groove, and the seal contacts and abuts against the adjacent nut.

[0028] The following is combined with Figure 1-7 This application is described in further detail.

[0029] Embodiment 1: Reference Figure 1 and Figure 2 The embodiment of the present application discloses a roof beam support column foot support, which is used for construction workers to construct beam support columns on the supporting steel beam 8 (i.e., support column beam) of the roof 7, so as to facilitate the construction workers to subsequently construct steel structures above the roof 7. In this embodiment, the supporting steel beam 8 is preferably an I-beam; in practical applications, in order to improve the structural strength of the supporting steel beam 8 (i.e., improve its supporting effect), the supporting steel beam 8 is preferably provided with a plurality of reinforcing ribs for strengthening the structure in the space on both sides of the I-beam.

[0030] Reference Figure 1 and Figure 3 The beam supporting column comprises a column body 1 and a column foot support 2, and the column body 1 is constructed above the supporting steel beam 8 through the column foot support 2. In this embodiment, the column body 1 is preferably a square steel pipe column.

[0031] Reference Figure 2 and Figure 3 The column foot support 2 includes a lower support 3, an upper support 4 and a plurality of connection components 5. The lower support 3 is used to be pre-installed and fixed on the supporting steel beam 8, so that subsequent construction workers can construct the beam support column above the roof 7; the upper support 4 is used to facilitate construction workers to connect the column 1 with the lower support 3; the connection component 5 is used to form a connection between the upper support 4 and the lower support 3.

[0032] The lower support 3 includes a first support member 31 and a first connecting plate 32. The first support member 31 is used for fixedly connecting the lower support 3 with the supporting steel beam 8; the first connecting plate 32 is used for forming a connection between the lower support 3 and the upper support 4.

[0033] The first support member 31 is a cross-plate structure, formed by a combination of multiple vertical plates; the first connecting plate 32 is a square plate structure, and the first connecting plate 32 is fixedly installed at one end of the cross extension track of the first support member 31. The cross directions of the first support member 31 are respectively parallel to the different side lengths of the first connecting plate 32, and the center of the first support member 31 and the center of the first connecting plate 32 are aligned along the cross extension track of the first support member 31. In this embodiment, it is preferred that the first support member 31 and the first connecting plate 32 are both steel structures, and it is preferred that the first support member 31 and the first connecting plate 32 are fixedly connected by welding.

[0034] One end of the first support member 31 away from the first connecting plate 32 is fixedly connected to the supporting steel beam 8. At this time, the first connecting plate 32 is located above the supporting steel beam 8 and is in a state where the square surface is parallel to the supporting steel beam 8. At this time, a construction space 6 sufficient for the construction and molding of the roof 7 is formed below the first connecting plate 32 and above the supporting steel beam 8. In this embodiment, it is preferred that the first support member 31 and the supporting steel beam 8 are fixedly connected by welding, and it is preferred that after the roof 7 is constructed on the supporting steel beam 8, the first connecting plate 32 will be located above the roof 7, that is, there is a certain distance between the surface of the top of the roof 7 and the first connecting plate 32 in the vertical direction.

[0035] Furthermore, the first support member 31 preferably contracts along its center line in a direction away from the first connecting plate 32 , and the cross-sectional area of ​​the first support member 31 away from the first connecting plate 32 is smaller than the cross-sectional area of ​​the first support member 31 close to the first connecting plate 32 .

[0036] Since the cross-sectional area of ​​the first support member 31 away from the first connecting plate 32 is reduced, when the first support member 31 and the supporting steel beam 8 are fixedly connected by welding, the scale of the weld that the construction workers need to weld is relatively small, which can facilitate the welding construction of the construction workers.

[0037] Moreover, compared with one end of the column 1 being directly welded and fixed to the supporting steel beam 8, the square trajectory formed by the weld is closed-loop and larger in scale, and the supporting steel beam 8 is also subjected to greater stress and deformation during its welding process; and after the first support member 31 is fixedly connected to the supporting steel beam 8, the weld between it and the supporting steel beam 8 is more concentrated and smaller in scale, and the supporting steel beam 8 is also subjected to less stress and deformation during its welding process.

[0038] Therefore, during the welding process of the end of the first support member 31 away from the first connecting plate 32 and the supporting steel beam 8, the welding construction process of the construction personnel can be effectively reduced, and at the same time, the impact on the supporting steel beam 8 during the welding process can be reduced, thereby ensuring the structural strength of the supporting steel beam 8.

[0039] After the lower support 3 is fixedly connected to the supporting steel beam 8 and the construction of the roof 7 is completed, there is still space in the construction space 6 below the first connecting plate 32 for the construction of structures such as the leveling layer and the waterproof layer, thereby reducing the probability of leakage of the roof 7 near the first support member 31.

[0040] The upper support 4 includes a second connecting plate 41, a second support member 42 and a third connecting plate 43. The second connecting plate 41 is used to form a connection between the upper support 4 and the lower support 3; the third connecting plate 43 is used to form a connection between the upper support 4 and the column 1; and the second support member 42 is used to form a connection between the second connecting plate 41 and the third connecting plate 43.

[0041] The second connecting plate 41 and the third connecting plate 43 are both in a square plate-like structure, and the second support member 42 is also in a cross-plate-like structure, and is also formed by a combination of multiple vertical plates. The second connecting plate 41 and the third connecting plate 43 are respectively fixedly installed at the two ends of the cross extension track of the second support member 42, and the cross direction of the second support member 42 is parallel to the different side lengths of the second connecting plate 41 and the different side lengths of the third connecting plate 43, respectively. The square surface of the second connecting plate 41 is parallel to the square surface of the third connecting plate 43, and the center of the second support member 42, the center of the second connecting plate 41, and the center of the third connecting plate 43 are all aligned along the cross track of the second support member 42. In this embodiment, it is preferred that the second support member 42, the second connecting plate 41, and the third connecting plate 43 are all steel structures, and it is preferred that the second support member 42 is fixedly connected to the second connecting plate 41 and the third connecting plate 43 by welding.

[0042] One end of the column 1 in the length direction is fixedly connected to the third connecting plate 43, at which time the length direction of the column 1 is parallel to the cross extension direction of the second support member 42, the side length of the square cross section on the column 1 is parallel to the side length of the third connecting plate 43, and the center line of the column 1 along its own length direction is aligned with the center of the third connecting plate 43. In this embodiment, it is preferred that the column 1 and the third connecting plate 43 are also fixedly connected by welding.

[0043] The upper support 4 and the lower support 3 are detachably connected through a plurality of connecting components 5. After the upper support 4 and the lower support 3 are connected, the second connecting plate 41 and the first connecting plate 32 are in contact with each other, and at this time, the center line of the column 1 coincides with the center line of the first support member 31 along its own cross extension direction. In this embodiment, preferably, the upper support 4 and the lower support 3 are detachably connected through a total of four connecting components 5.

[0044] The connecting assembly 5 includes a screw rod 51 , a washer 52 and two nuts 53 .

[0045] The first connecting plate 32 is provided with four through holes 321 for the tail of the screw 51 to pass through, the axis of the through hole 321 is perpendicular to the square surface of the first connecting plate 32, and the four through holes 321 are symmetrically distributed on the first connecting plate 32. In this embodiment, the aperture size of the through hole 321 is preferably larger than the radial size of the tail of the screw 51 and smaller than the radial size of the head of the screw 51.

[0046] The second connecting plate 41 is provided with four clearance grooves 411 for the tail of the screw rod 51 to pass through. When the first connecting plate 32 and the second connecting plate 41 are in contact with each other and the centers are aligned, the four clearance grooves 411 will be respectively connected with the four through holes 321. In this embodiment, the cross-sectional dimensions of the clearance grooves 411 are preferably larger than the radial dimensions of the tail of the screw rod 51, and the four clearance grooves 411 are preferably formed along the side length direction of the second connecting plate 41 to form an opening on one side of the adjacent side length of the second connecting plate 41, so that the construction personnel can easily open the clearance grooves 411 on the second connecting plate 41.

[0047] The gasket 52 is a square sheet structure as a whole, and a clearance hole 521 is provided on the gasket 52 for the tail of the screw 51 to pass through. In this embodiment, the size of the square of the gasket 52 is preferably larger than the cross-sectional size of the clearance groove 411, and the aperture size of the clearance hole 521 is preferably larger than the radial size of the tail of the screw 51 and smaller than the radial size of the nut 53.

[0048] The nut 53 can be matched with the tail thread of the screw rod 51. When the upper support 4 is installed above the lower support 3 and the first connecting plate 32 contacts and abuts against the surface of the second connecting plate 41, the gasket 52 is placed above the second connecting plate 41 to cover the corresponding part of the clearance groove 411. Then the tail of the screw rod 51 is passed through the through hole 321, the clearance groove 411 and the clearance hole 521 from bottom to top with the tail facing upward, so that the head of the screw rod 51 contacts and abuts against the bottom of the first connecting plate 32. Then, the two nuts 53 are matched with the tail threads of the corresponding screw rods 51 in turn, so that one nut 53 contacts and abuts against the top of the gasket 52 and drives the gasket 52 to abut against the second connecting plate 41, and the other nut 53 contacts and abuts against the nut 53 above the above nut 53. At this time, the column 1 can be fixedly connected with the upper support 4 and the lower support 3 through multiple connecting components 5, and the construction of the beam support column is completed.

[0049] The implementation principle of a roof beam support column foot support in the embodiment of the present application is: Before constructing the roof 7 on the supporting steel beam 8, the lower support 3 is welded and fixed on the supporting steel beam 8 in advance, and then the roof 7 is constructed; After the roof 7 is constructed, the upper support 4 of the column 1 is connected to the lower support 3 through a plurality of connecting components 5, and the position state of the column 1 after construction can be adjusted according to the construction requirements of the specific steel structure during the above construction process, thereby improving the flexibility of the beam support column construction and effectively making the beam support column construction process more convenient and quick; After the construction of the steel structure is completed, the force acting on the steel structure is applied to the beam support column. The force acting on the column 1 will be transmitted to the upper support 4, multiple connecting components 5 and the lower support 3 in succession, and finally transmitted to the supporting steel beam 8. The force can be gradually consumed in the process of transmission, thereby effectively reducing the probability of the beam support column being damaged after the force acting on the supporting steel beam 8 of the roof 7 directly acts on it.

[0050] Embodiment 2: Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 lies in the upper support 4 and the lower support 3.

[0051] Reference Figure 4 In order to improve the degree of alignment of the centers of the upper support 4 and the lower support 3 when determining the installation position, so that the force transmitted on the beam support column when the beam support column provides support for the steel structure later is more evenly distributed, thereby improving the overall structural stability of the beam support column; at the same time, in order to meet the flexibility of position adjustment required in the process of forming a connection between the support 4 above the column 1 and the lower support 3 through multiple connecting components 5; it is preferred that the lower support 3 is provided with a positioning groove 322 on the side of the first connecting plate 32 away from the first support member 31, and the upper support 4 is provided with a positioning block 412 adapted to the positioning groove 322 on the side of the second connecting plate 41 away from the second support member 42.

[0052] The positioning groove 322 is located at the center of the first connecting plate 32, and the positioning block 412 is located at the center of the second connecting plate 41. When the first connecting plate 32 and the second connecting plate 41 are in a center-aligned position, the positioning block 412 will be inserted into the positioning groove 322 to achieve plug-in fit, which can facilitate construction personnel to determine the installation position of the upper support 4 on the lower support 3, thereby making the construction process of the beam support column more convenient and quick.

[0053] Furthermore, it is preferred that the positioning block 412 is a cylindrical 1 structure as a whole, and the axis of the positioning block 412 is perpendicular to the square surface of the second connecting plate 41 .

[0054] When the positioning block 412 is plugged into the positioning groove 322, the upper support 4 together with the column 1 can rotate relative to the lower support 3 with the axis of the positioning block 412 as the axis, so that it is convenient for construction personnel to adjust the position of the column 1 according to the needs of subsequent steel structure construction. In this embodiment, the size of the preferably giving way groove 411 can meet the needs of a small range of rotation adjustment of the upper support 4 relative to the lower support 3.

[0055] The implementation principle of a roof beam support column foot support in the embodiment of the present application is: During the process of the upper support 4 of the column 1 forming a fixed connection with the lower support 3 through multiple connecting components 5, the positioning block 412 is controlled to be plugged into the positioning groove 322 to preliminarily determine the installation position of the upper support 4 on the lower support 3. According to the construction requirements of the subsequent steel structure, the upper support 4 is controlled to rotate and adjust to the required position relative to the lower support 3, and then the relative position between the upper support 4 and the lower support 3 is fixed through multiple connecting components 5, which can make the subsequent construction of the steel structure more convenient.

[0056] Embodiment 3: Reference Figure 2 and Figure 5 The difference between this embodiment and embodiment 2 lies in the connecting component 5 , which also includes a sealing member 54 .

[0057] Reference Figure 6 and Figure 7 The sealing member 54 is in an overall ring structure and has a certain elastic deformation capability. In this embodiment, the sealing member 54 is preferably made of rubber material.

[0058] The gasket 52 has a snap-fit ​​groove 522 on its square surface on one side thereof, which is adapted to the seal 54, and the snap-fit ​​groove 522 is also in a circular ring structure. The axis of the snap-fit ​​groove 522 coincides with the axis of the through hole 321, and when the connecting assembly 5 is used to form a connection between the upper support 4 and the lower support 3, the nut 53 that contacts and abuts against the top of the gasket 52 can cover the corresponding snap-fit ​​groove 522.

[0059] The clamping groove 522 includes a first groove 5221 and a second groove 5222 adapted to the end of the sealing member 54 . The first groove 5221 and the second groove 5222 are both annular structures as a whole, and the first groove 5221 is located between the second groove 5222 and the corresponding clearance hole 521 .

[0060] The end portion of the seal 54 can be snap-fitted with the first groove 5221 or the second groove 5222. When the end portion of the seal 54 is snapped into the first groove 5221 or the second groove 5222, a portion of the seal 54 is located outside the snap-fit ​​groove 522. The nut 53 can be restricted by the seal 54 during the threaded fit between the nut 53 and the tail of the screw 51. After contacting the portion of the seal 54 outside the snap-fit ​​groove 522, a certain distance is maintained between the nut 53 and the gasket 52. In this embodiment, the end portion of the seal 54 is preferably snap-fitted with the first groove 5221 or the second groove 5222 by interference fit.

[0061] Reference Figure 5 and Figure 6 In this state, the column 1 can form a preliminary connection between the upper support 4 and the lower support 3 through multiple connecting components 5. At the same time, the construction personnel can rotate and adjust the upper support 4 relative to the lower support 3 according to the needs of subsequent steel structure construction.

[0062] Reference Figure 5 and Figure 7 After the position state of the column 1 is adjusted, the construction personnel control the nut 53 to further threadably engage with the tail of the screw 51, and the seal 54 will bend and deform under the extrusion of the nut 53, and completely enter the snap-in groove 522 to fill the snap-in groove 522, so that the seal 54 is snap-fitted with the first groove 5221 and the second groove 5222 at the same time, and at this time, the part of the seal 54 close to the nut 53 will be pressed against the nut 53 in an extruded state.

[0063] In this state, the seal 54 can perform a sealing effect between the nut 53 and the gasket 52, reducing the entry of external moisture (such as rainwater) through the gap between the nut 53 and the gasket 52 and causing rust on the tail of the screw 51, thereby effectively extending the service life of the screw 51 and improving the reliability of the connection assembly 5.

[0064] The implementation principle of a roof beam support column foot support in the embodiment of the present application is: In the process of forming a fixed connection between the upper support 4 of the column 1 and the lower support 3 through multiple connecting components 5, the seal 54 is first installed in a state where the end portion is engaged with the first groove 5221 or the second groove 5222, and then a nut 53 is preliminarily threadedly engaged with the tail of the screw 51 so that the nut 53 and the portion of the seal 54 outside the engaging groove 522 are abutted against each other. At this time, the column 1 has formed a preliminary connection with the upper support 4 and the lower support 3 through multiple connecting components 5; Then, the position state of the column 1 is adjusted according to the requirements of the subsequent steel structure construction. After the final installation position of the upper support 4 above the lower support 3 is determined, the above-mentioned nut 53 is further matched with the tail thread of the screw 51, driving the corresponding seal 54 to bend and deform to fill the snap-in groove 522, and at the same time make its part press against the adjacent nut 53. At this time, the column 1 forms a fixed connection between the upper support 4 and the lower support 3 through multiple connecting components 5.
