Technical Field

[0001] This application relates to the field of curtain walls, and in particular to a supporting structure for curtain walls and its installation process. Background Art

[0002] A curtain wall is the external wall enclosure of a building, which does not bear weight and is hung like a curtain, so it is also called a "curtain wall". It is mainly composed of decorative panels and a supporting structure system, and is a lightweight wall with a decorative effect commonly used in modern large-scale and high-rise buildings.

[0003] In related technologies, a supporting structure for a curtain wall includes columns and crossbeams. The columns are vertical, and two columns are arranged at intervals in the horizontal direction, and both columns are fixed to the exterior wall of the building or the lower ends of both columns are fixed to the floor of the building. The crossbeam is horizontal, located between the two columns, and both ends of the crossbeam are respectively abutted against the two columns. Both ends of the crossbeam are fixed to the corresponding columns through fasteners and angle plates. The fasteners are generally rivets or bolts, and multiple crossbeams are arranged vertically on the columns. In actual installation, first, the two columns are fixed to the exterior wall of the building or the floor, then the crossbeam is placed between the two columns, and the two side plates of the angle plate are respectively nailed to the column and the crossbeam through rivets and bolts. After that, the decorative panels of the curtain wall can be installed between two adjacent crossbeams.

[0004] With the above scheme, when installing a crossbeam with a relatively large length, the middle part of the crossbeam is prone to deflection, and it is relatively more difficult to control the distance between two adjacent crossbeams and the installation error is relatively large, which will result in poor installation quality of the curtain wall and there is room for improvement. Summary of the Invention

[0005] In order to improve the problem that it is difficult to control the distance between two adjacent crossbeams during the installation of a crossbeam with a relatively large length in related technologies, resulting in relatively large installation errors and poor installation quality of the curtain wall, this application provides a supporting structure for curtain walls and its installation process.

[0006] In a first aspect, a supporting structure for curtain walls provided by this application adopts the following technical solution:

[0007] A supporting structure for curtain walls includes columns. The columns are vertical and fixed to the building. Two columns are arranged in parallel at intervals in the horizontal direction. A crossbeam is arranged between the two columns. The crossbeam is horizontal, and fixed components are respectively connected between both ends of the crossbeam and the two columns, and multiple crossbeams are evenly arranged at intervals in the vertical direction;

[0008] A temporary support frame is arranged between the two columns. The temporary support frame includes a vertical frame and a bearing layer frame. The vertical frame is detachably fixed to the building. The bearing layer frame is arranged on the vertical frame in a lifting manner, and a fastening component is fixed between the bearing layer frame and the vertical frame;

The middle part of the cross beam is supported by the bearing layer frame, and both ends of the cross beam are fixed to the columns through the corresponding fixing components. After all the cross beams are installed, the temporary support frame can be removed. In this way, the situation of the middle part of the longer cross beam deflecting downward is reduced, and it helps to reduce the error of the distance between two adjacent longer cross beams, which helps to improve the installation quality of the curtain wall.

[0011] Preferably, the fixing component includes a fixing frame fixed to the column. An embedding groove is provided at the end of the cross beam close to the fixing frame.

[0015] Preferably, a first waist-shaped hole is opened from top to bottom at one end of the cross beam on the fixing frame. The length direction of the first waist-shaped hole is parallel to the length direction of the cross beam. The fixing component further includes a fixing bolt and a fixing nut. The fixing bolt passes through the fixing frame and the first waist-shaped hole, and the fixing nut is threadedly connected to the end of the fixing bolt.

[0016] By adopting the above technical solution, during actual installation, the staff can adjust the relative position between the cross beam and the fixing frame along the length direction of the cross beam, and then lock and fix the cross beam and the fixing frame by the cooperation of the fixing bolts and the fixing nuts, which helps to ensure the correctness of the relative position between two adjacent cross beams.

[0017] Preferably, a second waist-shaped hole is formed in the fixing frame from top to bottom, the length direction of the second waist-shaped hole is perpendicular to the length direction of the cross beam, the fixing assembly further includes a fixing bolt and a fixing nut, the fixing bolt passes through the second waist-shaped hole and the cross beam, and the fixing nut is threadedly connected to the end of the fixing bolt.

[0019] Preferably, a structural beam is fixed between the upper ends of the two columns, and tie rods are vertically fixed between the structural beam and the adjacent cross beam, between two adjacent cross beams, and between the lower side of the lowermost cross beam and the building.

[0020] By adopting the above technical solution, the cross beam is pulled and supported by the tie rods, which helps to ensure the stability of the cross beam.

[0021] Preferably, threaded sleeves are rotatably connected to both sides of the upper side of the cross beam, and the end parts of the adjacent tie rods on the upper and lower sides of the cross beam respectively penetrate into the corresponding threaded sleeves and are threadedly connected to the corresponding threaded sleeves.

[0022] By adopting the above technical solution, the threaded sleeves and the tie rods are in threaded cooperation, which facilitates the installation of the tie rods and helps to ensure the normal adjustment operation of the cross beam.

A temporary support frame 3 is arranged between the two columns 1. The temporary support frame 3 includes an upright frame 31 and a bearing layer frame 32. The lower side of the upright frame 31 is fixed to the floor of the building. The bearing layer frame 32 is arranged to be lifted and lowered on the upright frame 31, and a fastening component is fixed between the bearing layer frame 32 and the upright frame 31. A cross beam 4 is also arranged between the two columns 1. The cross beam 4 is horizontal, the middle part of the cross beam 4 is erected on the bearing layer frame 32, and fixing components 5 are respectively fixed between the two ends of the cross beam 4 and the two columns 1. Moreover, a plurality of cross beams 4 are arranged at equal intervals in the vertical direction, and the fixing components 5, the bearing layer frame 32 and the fastening component are all arranged corresponding to the cross beam 4.

[0050] In actual use, first fix the two columns 1 on the floor of the building, and fix the structural beam 2 on the upper ends of the two columns 1; then, install the upright frame 31 between the two columns 1, and install the bearing layer frame 32 on the upright frame 31. At this time, the height of the bearing layer frame 32 can be adjusted, and the bearing layer frame 32 and the upright frame 31 are fixedly connected through the fastening component; then, hoist the cross beam 4 so that the middle part of the cross beam 4 is erected on the bearing layer frame 32, and the bearing layer frame 32 supports and positions the cross beam 4; finally, fix the two ends of the cross beam 4 to the two columns 1 respectively through two groups of fixing components 5. After the installation of all the cross beams 4 is completed, the temporary support frame 3 can be removed.

[0051] Specifically, refer to Figure 1 and Figure 2 , the upright frame 31 includes two side frames 311, and the two side frames 311 are respectively located on both sides of the width direction of the cross beam 4. The structures of the two side frames 311 are the same, and the structures of each layer of the bearing layer frame 32 are the same. Now, one of the side frames 311 and one layer of the bearing layer frame 32 are taken as examples for description.

[0052] The side frame 311 includes a vertical pipe 3111 and a horizontal pipe 3112. Two vertical pipes 3111 are arranged in parallel at intervals along the length direction of the cross beam 4. The cross beam 4 is located between the two vertical pipes 3111. The two ends of the horizontal pipe 3112 are respectively locked and fixed to the two vertical pipes 3111 through scaffolding fasteners, and a plurality of horizontal pipes 3112 are arranged at equal intervals in the vertical direction on the vertical pipes 3111. Moreover, a plurality of vertical pipes 3111 can be arranged in the vertical direction, and the adjacent two vertical pipes 3111 are connected through scaffolding fasteners, so as to ensure that the side frame 311 has sufficient height.

[0053] The bearing rack 32 includes two bearing pipes 321 arranged at intervals along the length direction of the cross beam 4, and the axes of the two bearing pipes 321 are both arranged along the width direction of the cross beam 4. The fastening component is an adjustable fastener 33, and both ends of each bearing pipe 321 are fixedly connected to two vertical pipes 3111 arranged along the width direction of the cross beam 4 of the vertical rack 31 through the adjustable fastener 33 respectively. To improve the stability of the support for the cross beam 4, three vertical racks 31 are evenly arranged at intervals along the length direction of the cross beam 4. When installing the cross beam 4, the bearing racks 32 are installed sequentially from bottom to top, and the cross beam 4 is installed together with the bearing racks 32 from bottom to top. That is, after installing each layer of bearing rack 32, the corresponding layer of cross beam 4 is installed accordingly, reducing the obstruction of the upper bearing rack 32 to the installation of the lower cross beam 4, thereby helping to ensure the convenience of installing the cross beam 4.

The fixing component 5 includes a fixing frame 51, and the fixing frame 51 is welded and fixed to the column 1. An embedding groove 41 is provided at the end of the cross beam 4 close to the fixing frame 51, the fixing frame 51 is embedded in the embedding groove 41, and gaps are reserved between the fixing frame 51 and the upper and lower side walls of the embedding groove 41 respectively. An adjusting member is further provided at the end of the cross beam 4, and the adjusting member is a gasket 6, and a plurality of gaskets 6 are provided between the upper side of the fixing frame 51 and the upper side wall of the embedding groove 41 and between the fixing frame 51 and the lower side wall of the embedding groove 41 respectively. In actual installation, gaskets 6 with the same thickness are first installed in the two gaps between the fixing frame 51 and the upper and lower side walls of the embedding groove 41, so that the fixing frame 51 is centered in the embedding groove 41, and then the fixing frame 51 is welded to the column 1. When there is an error in the levelness of the cross beam 4, the height of one end of the cross beam 4 can be adjusted by increasing the thickness of the gasket 6 on the lower side of the fixing frame 51 and decreasing the thickness of the gasket 6 on the upper side of the fixing frame 51 to raise the height of one end of the cross beam 4; or by decreasing the thickness of the gasket 6 on the lower side of the fixing frame 51 and increasing the thickness of the gasket 6 on the upper side of the fixing frame 51 to lower the height of one end of the cross beam 4, thereby realizing the adjustment of the levelness of the cross beam 4.

[0055] The fixing component 5 further includes a fixing bolt 52 and a fixing nut 53. A first waist-shaped hole 42 is opened from top to bottom at the end of each cross beam 4, the length direction of the first waist-shaped hole 42 is parallel to the length direction of the cross beam 4, a second waist-shaped hole 511 is opened from top to bottom on the fixing frame 51, and the length direction of the second waist-shaped hole 511 is parallel to the width direction of the cross beam 4. The fixing bolt 52 penetrates through the first waist-shaped hole 42 and the second waist-shaped hole 511, and the fixing nut 53 is threadedly connected to the end of the fixing bolt 52. In actual application, the position of the cross beam 4 can be adjusted along the length directions of the first waist-shaped hole 42 and the second waist-shaped hole 511, and the fixing frame 51 and the cross beam 4 are locked and fixed through the cooperation of the fixing bolt 52 and the fixing nut 53.

[0056] See Figure 1 and Figure 2 To ensure the stability of the cross beam 4 after the temporary support frame 3 is removed, tie rods 7 are vertically arranged between the lower side of the lowermost cross beam 4 and the floor of the building, between two adjacent cross beams 4, and between the structural beam 2 and the adjacent cross beam 4. The axes of all the tie rods 7 are collinear. Embedded parts 8 are pre-buried on the floor of the building. Threaded sleeves 71 are vertically arranged on the upper side of the embedded parts 8, the upper and lower sides of the cross beam 4. The threaded sleeves 71 on the embedded parts 8 are fixedly connected to the embedded parts 8, and the threaded sleeves 71 on the cross beam 4 are rotatably connected to the corresponding cross beam 4. Among them, between the floor of the building and the lowermost cross beam 4, and between two adjacent cross beams 4, the two ends of each tie rod 7 respectively penetrate into the corresponding two threaded sleeves 71 and are threadedly connected to the threaded sleeves 71; between the structural beam 2 and the uppermost cross beam 4, the upper end of the corresponding tie rod 7 is fixed to the structural beam 2, and the lower end of the tie rod 7 penetrates into the corresponding threaded sleeve 71 and is threadedly connected to the threaded sleeve 71. And, the tie rods 7 that are coaxial in the vertical direction are in a group. The tie rods 7 are arranged in two groups in the width direction of the cross beam 4. The two groups of tie rods 7 are in a row. The tie rods 7 are evenly spaced in six rows in the length direction of the cross beam 4, and the threaded sleeves 71 are arranged corresponding to the tie rods 7.

[0057] The embodiment of the present application also discloses an installation process of a supporting structure for a curtain wall, including the following steps,

[0058] S1. Install the outer frame. Fix the two columns 1 on the floor of the building, and fixedly install the structural beam 2 between the upper ends of the two columns 1.

[0059] S2. Install the vertical frames 31. Three vertical frames 31 are evenly spaced along the length direction of the structural beam 2 between the two columns 1, and the lower side of each side frame 311 is fixed on the floor of the building. In this embodiment, the lower end of the side frame 311 can be buried in the floor; or an installation seat can be pre-buried at the position corresponding to the vertical frame 31 on the floor of the building, and the vertical frame 31 is fixed on the installation seat.

[0060] S3. Install the load-bearing layer frame 32 and the cross beam 4.

[0061] S3.1. Install the single-layer load-bearing rack 32 and the cross beam 4. Install the single-layer load-bearing rack 32 on the three vertical racks 31 successively. Use a total station to measure and position the elevation of the load-bearing pipe 321 of the load-bearing rack 32, and have the staff move the load-bearing pipe 321 to the corresponding elevation. After being measured correctly by the total station, fix both load-bearing pipes 321 of the load-bearing rack 32 to the vertical rack 31 through adjustable fasteners 33. Then, hoist the cross beam 4 by a crane and place the middle part of the cross beam 4 on the three load-bearing racks 32. The load-bearing rack 32 positions the height of the cross beam 4 and supports the cross beam 4. Subsequently, install two fixing brackets 51 at both ends of the cross beam 4, so that the two fixing brackets 51 respectively penetrate into the embedding grooves 41 at both ends of the cross beam 4, and fill the same thickness of gaskets 6 in the two gaps between the installation brackets and the upper and lower side walls of the embedding grooves 41. At this time, the staff can move the cross beam 4 and the fixing brackets 51 so that the two fixing brackets 51 respectively abut against the two columns 1, and weld between each fixing bracket 51 and the corresponding column 1. Finally, pass the fixing bolt 52 through the first kidney-shaped hole 42 and the second kidney-shaped hole 511. At this time, the position of the cross beam 4 can be adjusted along the length directions of the first kidney-shaped hole 42 and the second kidney-shaped hole 511, and then thread the fixing nut 53 onto the end of the fixing bolt 52. The fixing bolt 52 and the fixing nut 53 cooperate to fix between the cross beam 4 and the fixing bracket 51.

[0062] After completing the fixation of the cross beam 4, install the tie rod 7 on the lower side of the cross beam 4, so that both ends of the tie rod 7 are respectively screwed into the two threaded sleeves 71.

[0063] It should be noted that in this embodiment, the fixing bolt 52 penetrates through each gasket 6 to reduce the occurrence of the gasket 6 falling off.

[0064] S3.2. Repeat step 3.1 to install the load-bearing rack 32 and the cross beam 4 from bottom to top until the installation of all cross beams 4 is completed.

[0065] Among them, when the height of the vertical pipe 3111 of the vertical rack 31 is insufficient, new vertical pipes 3111 can be connected upward through scaffolding fasteners to increase the height of the vertical rack 31.

[0066] S3.3. Install the tie rod 7 between the uppermost cross beam 4 and the structural beam 2, and fix the upper end of the tie rod 7 to the structural beam 2, and thread the lower end of the tie rod 7 onto the threaded sleeve 71 on the upper side of the uppermost cross beam 4.

[0067] S4. Dismantle the load-bearing rack 32 and the vertical rack 31.

[0068] Demolish the bearing layer rack 32 layer by layer from top to bottom. At the same time, use a total station to measure the cross beam 4 layer by layer as the bearing layer rack 32 is demolished. That is, demolish one layer of the bearing layer rack 32, then immediately measure the corresponding layer of the cross beam 4 and adjust and correct the corresponding layer of the cross beam 4.

[0069] When there is an error in the levelness of the cross beam 4, loosen the fixing bolts 52 and fixing nuts 53 at one end of the corresponding cross beam 4, take out the gasket 6 between the fixing frame 51 and the upper and lower side walls of the slot 41, and rotate the threaded sleeves 71 on the upper and lower sides of the corresponding cross beam 4 to lift or lower one side of the cross beam 4 through the pull rod 7. Then, fill the gasket 6 with the corresponding thickness between the fixing frame 51 and the upper and lower side walls of the slot 41. When the fixing frame 51 abuts against the upper side wall or the lower side wall of the slot 41, the gasket 6 with the corresponding thickness can be filled only between the fixing frame 51 and the lower side wall or the upper side wall of the slot 41.

[0070] At the same time, the position of the cross beam 4 can be adjusted again along the length directions of the first kidney-shaped hole 42 and the second kidney-shaped hole 511.

[0071] After adjustment, the fixing bolts 52 and fixing nuts 53 are used in cooperation to fix between the cross beam 4 and the fixing frame 51.

[0072] After the bearing layer rack 32 and the vertical rack 31 are demolished and all the cross beams 4 are corrected, the installation of the support structure for the curtain wall is completed.

[0073] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly.
