Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a column-supported beam structure and its construction method. Background Technology

[0002] In underground structures, different structural types are often used for the upper and lower parts of a floor due to its different functions, such as frame structures and shear wall structures. To achieve load transfer between these different structural types, transfer floors are needed at appropriate levels. Column transfer in underground structures is a common form of transfer, achieved by setting columns on transfer beams to transfer loads.

[0003] Currently, the authorized patent with publication number CN212453092U discloses a connection node structure between a steel transfer beam and a concrete column. In the connection node structure, the transfer beam is a pure steel structure, which does not require formwork or concrete pouring, thus improving the construction efficiency of the entire construction period. The concrete column is effectively connected to the first square steel pipe connector through studs. The bottom of the first square steel pipe connector is fixed to the upper flange of the steel beam, so that the connection strength and rigidity can be guaranteed.

[0004] In some buildings, the thickness of transfer beams is much greater than that of conventional transfer beams, reaching approximately 1.8 meters. When the thickness of the steel beam reaches 1.8 meters, the structural strength and rigidity of the steel beam will be greatly reduced, making it difficult to achieve stable support for the columns above the beam. Summary of the Invention

[0005] To address the instability issue when installing columns on thick transfer beams, this application provides a column-supporting structure and its construction method.

[0006] Firstly, the technical solution for a beam-supported column structure provided in this application is as follows:

[0007] A column-supported beam structure and its construction method are disclosed, comprising a support set inside a beam casting formwork, a steel reinforcement cage placed inside the beam casting formwork, the support located within the steel reinforcement cage, the bottom of the support being fixedly connected to the lower reinforcement of the steel reinforcement cage via a first connector, and a supporting steel member set at the top of the support, the supporting steel member comprising a steel beam and a steel column, the steel beam being set horizontally at the top of the support and located within the steel reinforcement cage, and the steel column being fixedly set vertically on the steel beam, the top of the steel column passing through the steel reinforcement cage and extending out of the beam casting formwork.

[0008] By adopting the above technical solution, a reinforcing steel cage is placed inside the casting formwork, and supporting steel components are installed within the reinforcing steel cage via supports. Concrete is then poured into the beam casting formwork, and after the concrete solidifies, a concrete transfer beam is formed. The top of the steel column extends out of the concrete transfer beam, facilitating the casting of the column on the beam. Furthermore, the steel beams within the concrete transfer beam reinforce the steel column, making the column cast on the beam more stable. This design, with pre-embedded supporting steel components within the concrete transfer beam, ensures that even with a large thickness, the column on the beam can still be stably installed on the concrete transfer beam.

[0009] Preferably, the support includes two first legs and multiple first connecting steel bars. The steel beam is set on the first legs. Each first leg is formed by two channel steel openings placed facing each other at intervals. The multiple first connecting steel bars connect four channel steels. The first connecting member is an angle steel. The two first connecting members are respectively located on the side of the two first legs that are far apart from each other. The side wall of the first connecting member is fixedly connected to the two channel steels of the first leg. The bottom wall of the first connecting member is fixedly connected to the lower steel bar of the steel reinforcement cage.

[0010] By adopting the above technical solution, the first angle steel connector is used to fix the channel steel of the first leg to the lower steel bar of the steel reinforcement cage, thereby fixing the support inside the steel reinforcement cage. The first connecting steel bar connects and fixes the four channel steels of the two first legs, making the supporting steel components more stable when installed on the support.

[0011] Preferably, two steel beams are provided, and the two steel beams are fixedly installed on both sides of the steel column. The steel beams are located in the two channel steels of the first leg, and the steel beams are placed on the topmost first connecting steel bar connecting the two channel steels of the first leg.

[0012] By adopting the above technical solution, when the supporting steel component is installed on the support, the two steel beams are respectively installed on the first connecting steel bars at the top of the two first legs, which can quickly complete the installation of the supporting steel component. In addition, the two channel steels in one first leg limit the steel beams, making the installation of the supporting steel component more stable.

[0013] Preferably, a second leg is provided at the end of the bottom wall of each of the two steel beams away from the first leg. The bottom end of the second leg is inclined away from the first leg. A plurality of second connecting steel bars are provided on the side wall of the second leg, and the second connecting steel bars are connected to the first leg.

[0014] By adopting the above technical solution, the second leg works together with the first leg to support the supporting steel component, and the second connecting steel bar connects the first leg and the second leg, thereby increasing the stability of the first leg and the second leg, and making the installation of the supporting steel component more stable.

[0015] Preferably, each of the two second legs has a second connector on its sidewalls that are close to each other at the bottom. The second connector is fixedly connected to the lower steel bar of the steel reinforcement cage. A connecting rod is provided on the second connector, and the end of the connecting rod away from the second connector is fixedly connected to the first connector.

[0016] By adopting the above technical solution, the second leg is fixed in the steel frame using the second connector, which further improves the stability of the second leg. The connecting rod connects the first connector and the second connector, thereby further improving the stability of the first leg and the second leg.

[0017] Preferably, a connecting beam is fixedly installed on the side wall of the steel column within the beam casting formwork along the direction perpendicular to the steel beam and the steel column, and the connecting beam is inserted into the longitudinal beam that is perpendicularly connected to the concrete transfer beam.

[0018] By adopting the above technical solution, after the concrete transfer beam is poured, the connecting beam extends horizontally through the side wall of the concrete transfer beam. When the longitudinal beam that is perpendicularly connected to the concrete transfer beam is poured, the connecting beam is inserted into the pouring formwork of the longitudinal beam, thereby making the connection between the longitudinal beam and the concrete transfer beam more stable.

[0019] Preferably, a connecting frame is provided on the connecting beam, and the end of the reinforcing cage inside the casting template of the longitudinal beam is tied and fixed to the connecting frame.

[0020] By adopting the above technical solution, before pouring the longitudinal beam, the end of the steel cage in the casting template of the longitudinal beam is tied and fixed to the connecting frame, so that the steel cage is fixedly connected to the connecting beam, and then fixedly connected to the supporting steel components, thereby further improving the stability of the longitudinal beam installation.

[0021] Preferably, the connecting frame includes two first sliding cylinders, a lifting column, a second sliding cylinder, a first frame, and a second frame. The two first sliding cylinders are respectively fixedly installed on the upper and lower side walls of the connecting beam. The two lifting columns are respectively slidably disposed in the two first sliding cylinders. The middle part of the side wall of the two second sliding cylinders is respectively fixedly connected to the ends of the two lifting columns away from the connecting beam. The ends of the first sliding cylinders are provided with first fixing members for fixing the lifting columns. The first frame and the second frame are both L-shaped. The ends of the two first frames that are close to each other are respectively slidably disposed at both ends of one second sliding cylinder. The ends of the two second frames that are close to each other are respectively slidably disposed at both ends of the other second sliding cylinder. The ends of the two first frames that are far from each other are respectively slidably disposed at the ends of the two second frames that are far from each other. The ends of the two second sliding cylinders are each provided with second fixing members for fixing the first frame or the second frame.

[0022] By adopting the above technical solution, two first frames and a second frame form a rectangular connecting frame. Two lifting columns slide within a first sliding cylinder. The lifting columns, via a second sliding cylinder, drive either the first or second frame to move up or down, thereby adjusting the height of the connecting frame. Sliding either the first or second frame within the second sliding cylinder adjusts the width of the connecting frame. After adjustment, the lifting columns, first frames, and second frames are fixed using first and second fixing components, thus completing the adjustment of the connecting frame's size. This configuration, by adjusting the size of the connecting frame, allows it to be used for connecting longitudinal beam reinforcement cages of different cross-sectional sizes.

[0023] Preferably, the first frame, the second frame, and the lifting column are all hollow, and each of the first frame, the second frame, the first slide cylinder, the second slide cylinder, and the lifting column has a pouring hole.

[0024] By adopting the above technical solution, when the longitudinal beam is poured, the poured concrete will enter the first frame, the second frame, the first slide cylinder, the second slide cylinder and the lifting column through the pouring hole. After the concrete solidifies, the structural strength of the connecting frame will be higher.

[0025] Secondly, the construction method for raising columns on beams provided in this application adopts the following technical solution:

[0026] A method for constructing columns on beams, using the aforementioned beam-on-column structure, includes the following construction steps: S1: Erecting a scaffold and installing beam casting formwork on the scaffold; S2: Placing a reinforcing steel cage inside the beam casting formwork; S3: Fixing supports inside the reinforcing steel cage; S4: Installing steel columns onto the supports via steel beams; S5: Pouring concrete inside the beam casting formwork; S6: After the concrete transfer beam has cured, casting the column on the beam at the top of the steel column extending from the concrete transfer beam.

[0027] By adopting the above technical solution, supporting steel components are pre-embedded in the concrete transfer beam, and the top of the steel column extends out of the concrete transfer beam, which facilitates the pouring of the column on the beam. In addition, the steel beam in the concrete transfer beam reinforces the steel column, making the column on the beam cast on the steel column more stable. When the thickness of the concrete transfer beam is large, the column on the beam can still be stably installed on the concrete transfer beam.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By using a concrete transfer beam extending from the top of the steel column, it is convenient to pour the column on the beam. The steel beam inside the concrete transfer beam reinforces the steel column, making the column on the beam cast on the steel column more stable. The pre-embedded supporting steel components in the concrete transfer beam ensure that the column on the beam can still be stably installed on the concrete transfer beam even when the concrete transfer beam is thick.

[0030] 2. By using connecting beams, after the concrete transfer beam is poured, the connecting beams extend horizontally from the side wall of the concrete transfer beam. When the longitudinal beams that are perpendicularly connected to the concrete transfer beam are poured, the connecting beams are inserted into the pouring formwork of the longitudinal beams, thereby making the connection between the longitudinal beams and the concrete transfer beam more stable.

[0031] 3. By using an adjustable-size connecting frame, the connecting frame can be adapted to connect longitudinal beam reinforcement cages of different cross-sectional sizes, thereby further improving the stability of longitudinal beam installation. Attached Figure Description

[0042] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0043] Example 1:

[0044] This application discloses a column-supported beam structure.

[0045] Reference Figure 1 and 2 A beam-supported column structure includes a support 1 and a supporting steel member 3. The support 1 is placed inside the beam casting formwork 16, and the supporting steel member 3 is installed on top of the support 1.

[0046] Specifically, the support 1 includes two first legs 11 and multiple first connecting steel bars 12. A steel reinforcement cage 17 is placed inside the beam casting formwork 16. The first legs 11 are located inside the steel reinforcement cage 17, and the bottom end of the first legs 11 abuts against the lower steel bars of the steel reinforcement cage 17. The bottom ends of the side walls of the two first legs 11 that are far apart from each other are welded and fixed with first connecting members 2. In this application, the first connecting members 2 can be selected as angle steel. The bottom wall of the first connecting members 2 is welded and fixed to the lower steel bars of the steel reinforcement cage 17, thereby fixing the first legs 11 inside the steel reinforcement cage 17.

[0047] Each first support leg 11 consists of two channel steels arranged vertically, with their open ends facing each other and spaced apart. A first connector 2 is welded and fixed to the two channel steels of one first support leg 11. Multiple first connecting reinforcing bars 12 consist of transverse and longitudinal reinforcing bars. The two ends of the longitudinal reinforcing bars are welded and fixed to the two channel steels of one support leg, and the two ends of the transverse reinforcing bars are welded and fixed to the two channel steels of two supports. The transverse reinforcing bars are also welded and fixed to the longitudinal reinforcing bars. The use of first connecting reinforcing bars 12 to reinforce the two first support legs 11 increases the structural strength of the support 1.

[0048] Specifically, the supporting steel component 3 includes a vertically installed steel column 32 and two horizontally installed steel beams 31. The two steel beams 31 are welded and fixed to the opposite side walls at the bottom of the steel column 32. The steel beams 31 are located within the beam casting formwork 16 and are installed along the length of the transfer beam. The bottom of the steel column 32 is located within the beam casting formwork 16, and the top of the steel column 32 extends outside the beam casting formwork 16. In this application, the steel beam 31 can be an I-beam, and the steel column 32 can be a square steel tube.

[0049] Two steel beams 31 are respectively installed at the top of the two first legs 11. Each steel beam 31 is located between two channel steels of each first leg 11. Each steel beam 31 overlaps the topmost longitudinal steel bar inside each first leg 11 and is welded and fixed to the channel steel. In this way, the supporting steel component 3 can be installed on the support 1, and the two channel steels inside the first leg 11 limit the position of the steel beam 31, making the supporting steel component 3 more stable on the support 1.

[0050] After the supporting steel component 3 is installed, concrete is poured into the beam casting formwork 16. The concrete submerges the support 1, the reinforcing steel cage 17, the steel beam 31, and the lower half of the steel column 32. After the concrete cures, the concrete transfer beam is formed. At this time, the upper half of the steel column 32 extends out of the concrete transfer beam, which facilitates the casting of the column on the beam. The steel beam 31 inside the concrete transfer beam reinforces the steel column 32, making the column cast on the beam more stable. In this way, by pre-embedding the supporting steel component 3 inside the concrete transfer beam, the column on the beam can still be stably installed on the concrete transfer beam even when the concrete transfer beam is thick.

[0051] Both steel beams 31 have a first reinforcing member 18 welded to one end of their top walls that is close to each other. The first reinforcing member 18 is T-shaped, and the ends of both first reinforcing members 18 that are close to each other are welded to the steel column 32. The first reinforcing member 18 reinforces the connection between the steel beam 31 and the steel column 32, making the steel column 32 less prone to tilting.

[0052] A connecting beam 8 is welded and fixed horizontally on the side wall between the two steel beams 31 at the bottom of the steel column 32. When the longitudinal beam that is perpendicularly connected to the concrete transfer beam is poured, the connecting beam 8 is inserted into the pouring template of the longitudinal beam. After the longitudinal beam is poured and cured, the connecting beam 8 is inserted and fixed in the longitudinal beam, so that the connection between the longitudinal beam and the concrete transfer beam is more stable.

[0053] A second reinforcing member 19 is welded and fixed to the connecting beam 8. The second reinforcing member 19 is T-shaped, and its end is welded and fixed to the steel column 32. Part of the second reinforcing member 19 is located inside the concrete transfer beam, and the other part is located inside the longitudinal beam. The second reinforcing member 19 reinforces the connection between the connecting beam 8 and the steel column 32, making the connecting beam 8 less prone to tilting.

[0054] The implementation principle of Embodiment 1 of this application is as follows: A reinforcing steel cage 17 is placed inside the casting template, and the supporting steel component 3 is installed inside the reinforcing steel cage 17 through the support 1. Concrete is poured into the beam casting template 16, and after the concrete solidifies, a concrete transfer beam is formed. The top of the steel column 32 extends out of the concrete transfer beam, which facilitates the casting of the column on the beam. The steel beam 31 inside the concrete transfer beam reinforces the steel column 32, making the column on the beam cast on the steel column 32 more stable. In this way, by pre-embedding the supporting steel component 3 inside the concrete transfer beam, the column on the beam can still be stably installed on the concrete transfer beam even when the concrete transfer beam is thick.

[0055] Example 2:

[0056] Reference Figure 3 The difference between this embodiment and Embodiment 1 is that the beam-supported column structure also includes two second legs 4. The structure of the second legs 4 is the same as that of the first legs 11. Two steel beams 31 are respectively installed on the top of the two second legs 4 and welded to the second legs 4. The two second legs 4 are located on the sides of the two first legs 11 that are far apart from each other, and the bottom of the second legs 4 is inclined away from the first legs 11. The second legs 4 work together with the first legs 11 to support the supporting steel member 3, making the supporting steel member 3 more stable.

[0057] A second connector 6 is welded and fixed to the bottom side wall of the second leg 4 near the first leg 11. The second connector 6 has an L-shaped cross-section, and its side wall fits against the second leg 4. Its bottom wall is welded and fixed to the lower reinforcing bars of the reinforcing steel frame 17. The second connector 6 is used to fix the second leg 4 to the reinforcing steel frame 17, thereby improving the stability of the second leg 4.

[0058] Each second leg 4 is equipped with multiple second connecting steel bars 5. The structure of the second connecting steel bars 5 is the same as that of the first connecting steel bars 12, and the second connecting steel bars 5 connect the second leg 4 and the first leg 11. Using the second connecting steel bars 5 to connect the second leg 4 and the first leg 11 can improve the stability of the second leg 4 and the first leg 11.

[0059] Three connecting rods 7 are welded and fixed to the side wall of the second connecting member 6 near the first leg 11. The ends of the three connecting rods 7 away from the second connecting member 6 are welded and fixed to the side wall of the first connecting member 2. The connecting rods 7 are used to weld and fix the first connecting member 2 and the second connecting member 6, thereby further improving the stability of the first leg 11 and the second leg 4.

[0060] The implementation principle of Embodiment 2 of this application is as follows: the second support leg 4 works in conjunction with the first support leg 11 to support the supporting steel component 3, and the second connector 6 and the second connecting steel bar 5 fix the second support leg 4, thereby making the supporting steel component 3 more stable on the bracket.

[0061] Example 3:

[0062] Reference Figure 4 and 5 The difference between this embodiment and embodiment 2 is that a connecting frame 9 is installed on the connecting beam 8, and the end of the reinforcing cage inside the longitudinal beam casting template 16 is tied and fixed to the connecting frame 9. Before pouring the longitudinal beam, the end of the reinforcing cage inside the longitudinal beam casting template 16 is tied and fixed to the connecting frame 9, so that the reinforcing cage is fixedly connected to the connecting beam 8, thereby further improving the stability of the longitudinal beam installation.

[0063] Reference Figure 5 and 6 The connecting frame 9 includes two first sliding cylinders 91, a lifting column 92, a second sliding cylinder 93, a first frame 94, and a second frame 95. The two first sliding cylinders 91 are welded and fixed to the middle of the upper and lower side walls of the connecting beam 8, respectively. The two lifting columns 92 are slidably installed in the two first sliding cylinders 91 in the vertical direction. The ends of the lifting columns 92 extend out of the first sliding cylinders 91, and the second sliding cylinder 93 is welded and fixed to the end of the lifting column 92 located outside the first sliding cylinder 91 in the direction perpendicular to the lifting column 92.

[0064] A lifting column 92 slides within the first slide cylinder 91, which in turn drives the second slide cylinder 93 to move up and down. A first fixing member 10 is threaded onto the end of the first slide cylinder 91 furthest from the connecting beam 8, and a deformation groove is formed at the end of the first slide cylinder 91 furthest from the connecting beam 8 to allow for deformation of the first slide cylinder 91. In this application, the first fixing member 10 is a fixing ring. Rotating the first fixing member 10 causes it to press against the first slide cylinder 91, causing the end of the first slide cylinder 91 to tighten and deform inward under the action of the deformation groove, thereby clamping and fixing the lifting column 92, and subsequently fixing the second slide cylinder 93.

[0065] Both the first frame 94 and the second frame 95 are L-shaped. The ends of the two first frames 94 that are close to each other are slidably installed horizontally at both ends of the first sliding cylinder 91 above the connecting beam 8. The ends of the two second frames 95 that are close to each other are slidably installed horizontally at both ends of the first sliding cylinder 91 below the connecting beam 8. The ends of the two first frames 94 that are far apart from each other are slidably installed vertically at the far ends of the two second frames 95. The two first frames 94 and the second frames 95 form a rectangular frame, and the ends of the reinforcing cage in the longitudinal beam casting formwork 16 are tied and fixed to the rectangular frame.

[0066] Both ends of the second slide cylinder 93 are threaded with second fixing members 13, and both ends of the second slide cylinder 93 are provided with deformation grooves for deformation of the second slide cylinder 93. In this application, the second fixing member 13 is a fixing ring. When the second fixing member 13 is rotated, the second fixing member 13 compresses the second slide cylinder 93, and the end of the second slide cylinder 93 is tightened and deformed inward under the action of the deformation groove, thereby clamping and fixing the first frame and the second frame.

[0067] When the second sliding cylinder 93 moves up and down, it drives the first frame 94 or the second frame 95 to move up and down as well, thereby adjusting the height of the frame. Sliding the first frame 94 and the second frame 95 horizontally within the second sliding cylinder 93 adjusts the width of the frame. By adjusting the size of the connecting frame 9, it can be adapted to tie longitudinal beam reinforcement cages of different cross-sectional sizes.

[0068] The first sliding cylinder 91, the lifting column 92, the second sliding cylinder 93, the first frame 94, and the second frame 95 are all hollow structures, and their internal cavities are interconnected. Multiple pouring holes 14 are provided on the side walls of each of these structures. When the longitudinal beam is poured, the concrete enters through the pouring holes 14 into the first sliding cylinder 91, the lifting column 92, the second sliding cylinder 93, the first frame 94, and the second frame 95. The interconnected internal cavities allow the concrete to quickly fill the connecting frame 9. After the concrete has hardened, it supports the connecting blocks inside the connecting frame 9, thus increasing the structural strength of the connecting frame 9.

[0069] The implementation principle of Embodiment 3 of this application is as follows: Before pouring the longitudinal beam, the end of the steel cage in the longitudinal beam pouring template 16 is tied and fixed to the connecting frame 9, so that the steel cage is fixedly connected to the connecting beam 8, thereby further improving the stability of the longitudinal beam installation; at the same time, by adjusting the size of the connecting frame 9, the connecting frame 9 can be adapted to the binding of longitudinal beam steel cages with different cross-sectional sizes.

[0070] Example 4:

[0071] This application discloses a method for constructing columns on beams.

[0072] Reference Figure 7 , 8 9. A method for releasing a column from a beam, employing the aforementioned column-raising structure, includes the following construction steps:

[0073] S1: Construct a frame 15 on the lower building surface, and assemble the beam casting formwork 16 at the top of the frame 15;

[0074] S2: Install the lower reinforcing bars of the reinforcing cage 17 into the casting formwork;

[0075] S3: Use hoisting equipment to hoist the support 1 into the beam casting formwork 16. Weld the first connector 2 to the bottom of the first leg 11 and fix the first connector 2 to the lower reinforcing bar. Weld the second connector 6 to the bottom of the second leg 4 and fix the second connector 6 to the lower reinforcing bar. Finally, weld the two ends of the connecting rod 7 to the first connector 2 and the second connector 6 to fix the support 1 into the beam casting formwork 16.

[0076] S4: Using hoisting equipment, the supporting steel component 3 is hoisted onto the first leg 11 and the second leg 4. Two steel beams 31 are placed on top of the first leg 11 and the second leg 4 respectively, and the steel beams 31 are welded and fixed to the first leg 11 and the second leg 4. The steel column 32 is installed inside the beam casting formwork 16 through the two steel beams 31, and the lower half of the steel column 32 is located inside the beam casting formwork 16, while the upper half of the steel column 32 is located outside the beam casting formwork 16.

[0077] S5: First, install the stirrups and upper reinforcement of the steel cage 17 into the casting form, and then pour concrete into the casting form.

[0078] S6: After the concrete transfer beam has cured, cast the upper column of the beam at the top of the steel column 32 extending from the concrete transfer beam, adjust the size of the connecting frame 9, first tie the end of the steel cage in the longitudinal beam casting template 16 to the adjusting frame, and then cast the longitudinal beam.

[0079] The implementation principle of Embodiment 4 of this application is as follows: a supporting steel component 3 is pre-embedded in the concrete transfer beam, the top of the steel column 32 extends out of the concrete transfer beam, which facilitates the pouring of the column on the beam, and the steel beam 31 in the concrete transfer beam reinforces the steel column 32, making the column on the beam cast on the steel column 32 more stable. When the thickness of the concrete transfer beam is large, the column on the beam can still be stably installed on the concrete transfer beam.

[0080] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
