A gable frame construction method

Abstract

This invention discloses a construction method for a gable wall space frame. The middle unit space frame is hoisted onto pre-set concrete columns for positioning, and then guy ropes are installed for temporary support. The positioned middle unit space frame serves as the starting support, and smaller unit space frames are installed laterally using a piecemeal method. The hoisted three-sided gable wall space frame is then connected to the arched portion of the space frame via the piecemeal method, forming a U-shape, resulting in higher structural stability. This combination of hoisting and piecemeal assembly reduces the frequency and risk of high-altitude work for construction personnel. While hoisting is difficult for large-span doorways, combining it with the piecemeal method facilitates crossing doorways and ensures stability. Hoisting large middle units reduces the number of cranes required. Furthermore, the space frame assembled using this method ensures a high stability coefficient and spatial stiffness, exhibiting good seismic performance.

Description

TECHNICAL FIELD

[0001] The present application relates to a gable frame construction method. BACKGROUND

[0002] In the field of construction, some shed structure buildings we commonly see, such as dry coal sheds, are mostly assembled from gables, arched supports and the like, as recorded in the patent literature of Chinese Patent Publication No. CN205955300U, the gable frame and arched support of which are assembled from a plurality of single unit frames. This type of frame assembly often uses high-altitude bulk loading method for assembly, and there is more high-altitude work and greater risk in the construction process. SUMMARY

[0003] The present application aims to provide a gable frame construction method that not only ensures the stability of the frame structure, but also reduces the frequency of high-altitude work for workers and the risk of high-altitude work.

[0004] To solve the above technical problems, the present application adopts the following technical solutions:

[0005] A gable frame construction method, comprising the following steps:

[0006] (1) dividing the ground into an assembly area, a construction area and a transfer station, and pre-setting concrete columns in the construction area;

[0007] (2) assembling two middle unit frames in the assembly area as a first gable frame and a first arched side frame; hoisting the first gable frame onto the pre-set concrete columns for positioning, and after positioning, pulling wind ropes on the inside and outside of the first gable frame, and adding supports on the inside;

[0008] At the same time, prepare to hoist the first arched side frame;

[0009] (3) hoist the first arched side frame onto the corresponding support and connect it with the first gable frame, after which the first gable frame and the first arched side frame form an L shape and are in a relatively stable state; the support is arranged on the corresponding concrete column;

[0010] (4) assemble a middle unit frame in the assembly area as a second gable frame, hoist the second gable frame onto the corresponding support for positioning, and after positioning, pull wind ropes on the second gable frame and make temporary supports; the support is arranged on the corresponding concrete column;

[0011] (5) assemble a plurality of small unit frames in the assembly area, and install the small unit frames on the second gable frame in a bulk loading method, the steps of which include:

[0012] a. Extend the small unit space frame towards the first gable wall space frame, install it onto the next support for fixation, and install temporary supports and guy ropes;

[0013] b. Spread the small unit space frame towards the first gable wall space frame, spanning the doorway between the first and second gable wall space frames, so that the first and second gable wall space frames are connected.

[0014] (6) While the small unit space frame is being installed in the second gable wall space frame, the unit space frame is being assembled in the assembly area as the third gable wall space frame; the third gable wall space frame is hoisted onto the pre-set concrete column for positioning, and then the third gable wall space frame is stretched with wind ropes and temporarily supported.

[0015] (7) Assemble multiple small unit space frames in the assembly area, and spread the small unit space frames on the third gable wall space frame using the bulk method. Spread the small unit space frames towards the second gable wall space frame, and at the same time spread the small unit space frames upward to prepare for the third gable wall space frame to cross the roof of the transfer station.

[0016] (8) The third gable wall space frame continues to spread upwards to install small unit space frames using the loose method. For every two grid units of small unit space frames that are spread upwards, a steel wire rope is pulled to stabilize the structure.

[0017] At the same time, the third gable wall space frame extends towards the second gable wall space frame to install small unit space frames to cross the roof of the transfer station;

[0018] At the same time, the first arched side space frame also spreads upward and towards the second gable wall space frame in a stepped manner to install small unit space frames. During the upward spreading installation of small unit space frames, once the second steel wire rope is installed, preparations begin for the connection between the second arched side space frame and the third gable wall space frame.

[0019] (9) Assemble several unit grids on the ground using small unit grids, and assemble the second arched side grid using the unit grids. The assembly steps of the second arched side grid include:

[0020] a. Lift one end of the first cell grid;

[0021] b. Along the pre-set arc of the second arched side grid, assemble the second unit grid to the end of the first unit grid that is being lifted, and then lower it;

[0022] c. Lift one end of the two assembled unit grids;

[0023] d. Along the pre-set arc of the second arched side grid, assemble the third unit grid onto the end where the first two unit grids are suspended, and then lower it;

[0024] The construction process involved repeatedly lifting and lowering the spheres until the 11 spheres on the upper chord side of the second arched side frame were completed.

[0025] The second arched side space frame, which was then assembled on the ground, was hoisted to the installation position and connected with the third gable wall space frame; steel wire ropes were then used to stabilize the structure.

[0026] (10) The first gable wall space frame, the second gable wall space frame and the third gable wall space frame that are connected to each other form a gable wall space frame on the same axis;

[0027] The gable space frame continues to expand upwards using a piecemeal method to install smaller unit space frames until the gable space frame is completely closed with the first arched side space frame and the second arched side space frame;

[0028] (11) After the first arched side space frame and the second arched side space frame are joined together, they form the arched part of the gable space frame. After the gable space frames on both sides of the current axis are joined together, the arched part of the space frame is installed in a diffused manner towards both sides of the axis as small unit space frames.

[0029] (12) After the small unit space frame is installed between the arched parts of the gable space frame on multiple axes, the expansion joints between them are connected and transitioned by ordinary mesh rods.

[0030] (13) Remove the temporary connecting rods and fill the missing parts of the gable wall space frame with rods; after the filling and replacement of rods are completed, the gable wall space frame is installed as a whole.

[0031] By adopting the above technical solutions, the construction of the gable space frame combines hoisting and assembly methods. The hoisting method reduces the frequency of high-altitude work for construction personnel and lowers the risks associated with such work. For large-span doorways, the assembly method is used for diffused installation, while also ensuring the stability of the space frame structure. The hoisting object is a medium-unit space frame assembled on the ground. As the volume of the hoisting object increases, the number of cranes required for hoisting is reduced, thus lowering the hoisting cost.

[0032] Furthermore, before assembling the medium and small unit space frames in the assembly area, the ground in the assembly area will be laid with sleepers or steel pipes, and a level will be used to measure and level it. If there are differences in elevation during the measurement, steel plates will be used for fine adjustment.

[0033] Furthermore, the members at the connection between the first arched side space frame and the first gable wall space frame in step (3) are temporary members, which will be removed after the gable wall space frame is fully constructed.

[0034] Furthermore, the small unit grid diffusion installation steps in step (5) include:

[0035] a. Assemble the first small unit space frame, which includes a sphere, a chord, and two web members, on the ground. Hoist the first small unit space frame to the installation position and manually assemble the first small unit space frame with the corresponding space frame.

[0036] b. Assemble the second small unit space frame, which includes a sphere, two chords and two web members, on the ground. Hoist the second small unit space frame to the installation position and manually assemble the second small unit space frame with the corresponding space frame.

[0037] c. Assemble the third small unit space frame, which includes a sphere, a chord, and two web members, on the ground. Hoist the third small unit space frame to the installation position and manually assemble the third small unit space frame with the corresponding space frame.

[0038] d. Assemble the fourth small unit space frame, which includes a sphere, two chords and one web member, on the ground. Hoist the fourth small unit space frame to the installation position and manually assemble the fourth small unit space frame with the corresponding space frame.

[0039] Furthermore, during the bulking process of the small unit space frame in step (7) spreading towards the second gable wall space frame, it will be fixed with the corresponding support, and temporary supports and wind ropes will be installed.

[0040] Furthermore, in step (9), the second arched side grid frame assembled on the ground needs to be lifted by two 75-ton cranes, with a total lifting weight of 16.48 tons.

[0041] Furthermore, in step (9), when the second arched side grid is hoisted across the belt conveyor, the second arched side grid needs to be temporarily supported. The support can be provided by using sleeper pads or by using steel pipes as temporary support pipes.

[0042] Furthermore, in step (9), the second arched side space frame needs to be slightly offset from the outside of the current axis when it is assembled on the ground to ensure that it does not affect the crane station position and the installation of the second arched side space frame when crossing the belt conveyor; at the same time, after the second arched side space frame is hoisted into place, it needs to be connected to the third gable wall space frame immediately, and the crane hook is released after the connection is completed.

[0043] Furthermore, in step (11), the arched portion of the space frame is installed in a loose, stepped manner to the side of the axis, with small unit space frames being diffused and installed.

[0044] Furthermore, in step (11), the arched portion of the space frame is installed in a manner of one row of upper chords and one row of lower chords towards the side of the axis to spread out the small unit space frame.

[0045] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0046] This invention combines hoisting and bulk assembly methods in its construction approach, which not only reduces the frequency and risk of high-altitude work for construction workers, but also ensures the structural stability of the space frame.

[0047] The object to be hoisted by this invention is an assembled medium-unit space frame, which can reduce the number of cranes required for hoisting and reduce hoisting costs;

[0048] The arched space frame of this invention spans large-span doorways using a cantilevered, high-altitude, loose-assembly method, which ensures stability and spatial stiffness, effectively withstands asymmetric loads, concentrated loads, and dynamic loads, and has good seismic performance.

[0049] This invention involves leveling the ground before assembling the intermediate and small unit space frames, which better ensures the structural accuracy of each intermediate and small unit space frame. Attached Figure Description

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. Example

[0079] A method for constructing a gable wall space frame includes the following steps:

[0080] (1) Divide the ground into areas, including assembly area, construction area and transfer station, and pre-set concrete columns in the construction area;

[0081] (2) Assemble two medium unit space frames in the assembly area as the first gable wall space frame and the first arched side space frame; hoist the first gable wall space frame onto the pre-set concrete column for positioning; after positioning, pull the wind ropes inside and outside the first gable wall space frame and add support on the inner side.

[0082] At the same time, preparations were made for hoisting the first arched side space frame;

[0083] (3) After hoisting the first arched side space frame onto the corresponding supports, it is connected to the first gable wall space frame. After the first gable wall space frame and the first arched side space frame are connected, they form an L-shape and are in a relatively stable state, such as Figure 7 As shown;

[0084] (4) Assemble a medium unit space frame in the assembly area as the second gable wall space frame, hoist the second gable wall space frame onto the corresponding support for positioning, and after positioning, pull the wind ropes and make temporary support for the second gable wall space frame.

[0085] (5) Assemble multiple small unit space frames in the assembly area, and then spread out the small unit space frames on the second gable wall space frame using the bulk method. The steps for spreading out the small unit space frames include:

[0086] a. Extend the small unit space frame towards the first gable wall space frame, install it onto the next support for fixation, and install temporary supports and guy ropes;

[0087] b. Spread the small unit space frame towards the first gable wall space frame, spanning the doorway between the first and second gable wall space frames, so that the first and second gable wall space frames are connected.

[0088] (6) While the small unit space frame is being installed in the second gable wall space frame, the unit space frame is being assembled in the assembly area as the third gable wall space frame; the third gable wall space frame is hoisted onto the pre-set concrete column for positioning, and then the third gable wall space frame is stretched with wind ropes and temporarily supported.

[0089] (7) Assemble multiple small unit space frames in the assembly area, and spread the small unit space frames on the third gable wall space frame using the bulk method. Spread the small unit space frames towards the second gable wall space frame, and at the same time spread the small unit space frames upward to prepare for the third gable wall space frame to cross the roof of the transfer station.

[0090] (8) The third gable wall space frame continues to spread upwards to install small unit space frames using the loose method. For every two grid units of small unit space frames that are spread upwards, a steel wire rope is pulled to stabilize the structure.

[0091] At the same time, the third gable wall space frame extends towards the second gable wall space frame to install small unit space frames to cross the roof of the transfer station;

[0092] At the same time, the first arched side space frame also spreads upward and towards the second gable wall space frame in a stepped manner to install small unit space frames. During the upward spreading installation of small unit space frames, once the second steel wire rope is installed, preparations begin for the connection between the second arched side space frame and the third gable wall space frame.

[0093] (9) Assemble several unit grids on the ground using small unit grids, and assemble the second arched side grid using the unit grids. The assembly steps of the second arched side grid include:

[0094] a. Lift one end of the first cell grid;

[0095] b. Along the pre-set arc of the second arched side grid, assemble the second unit grid to the end of the first unit grid that is being lifted, and then lower it;

[0096] c. Lift one end of the two assembled unit grids;

[0097] d. Along the pre-set arc of the second arched side grid, assemble the third unit grid onto the end where the first two unit grids are suspended, and then lower it;

[0098] The construction process involved repeatedly lifting and lowering the spheres until the 11 spheres on the upper chord side of the second arched side frame were completed.

[0099] The second arched side space frame, which was then assembled on the ground, was hoisted to the installation position and connected with the third gable wall space frame; steel wire ropes were then used to stabilize the structure.

[0100] (10) The first gable wall space frame, the second gable wall space frame and the third gable wall space frame that are connected to each other form a gable wall space frame on the same axis;

[0101] The gable space frame continues to expand upwards using a piecemeal method to install smaller unit space frames until the gable space frame is completely closed with the first arched side space frame and the second arched side space frame;

[0102] (11) After the first arched side space frame and the second arched side space frame are joined together, they form the arched part of the gable space frame. After the gable space frames on both sides of the current axis are joined together, the arched part of the space frame is installed in a diffused manner towards both sides of the axis as small unit space frames.

[0103] (12) After the small unit space frame is installed between the arched parts of the gable space frame on multiple axes, the expansion joints between them are connected and transitioned by ordinary mesh rods.

[0104] (13) Remove the temporary connecting rods and fill the missing parts of the gable wall space frame with rods; after the filling and replacement of rods are completed, the gable wall space frame is installed as a whole.

[0105] The intermediate unit space frame in step (2) is composed of multiple conical unit space frames. Figure 4 This is a schematic diagram of the assembly process of the medium-sized unit space frame. Figure 5 This is a schematic diagram of the structure after the middle unit space frame is assembled.

[0106] In this embodiment, supports for fixing the grid frame are provided on the concrete columns. The supports in steps (3), (4) and (5) are all provided on the concrete columns.

[0107] In this embodiment, the hoisting height of the first gable wall space frame is 20.4 meters, the hoisting weight is 7.61 tons, and the hoisting radius is 11 meters. Considering a safety factor of 1.3, a 50-ton mobile crane is required for hoisting.

[0108] In this embodiment, when the medium-sized and small-sized space frames are assembled in the assembly area, the ground is leveled using sleepers.

[0109] The members at the connection between the first arched side space frame and the first gable wall space frame in step (3) are temporary members, which will be removed after the gable wall space frame is fully constructed.

[0110] In this embodiment, the hoisting height of the first arched side grid is 20.4 meters, the hoisting weight is 8.4 tons, and the hoisting radius is 11 meters. Considering a safety factor of 1.3, a 50-ton truck crane is required for hoisting.

[0111] In this embodiment, the second gable wall space frame is hoisted at a height of 20.4 meters, weighs 6.97 tons, and has a hoisting radius of 11 meters. Considering a safety factor of 1.3, a 50-ton mobile crane is required for hoisting.

[0112] The small unit frame in step (5) includes sphere 3, chord 4, and web member 5, such as Figure 8 , Figure 9 As shown;

[0113] Step (5) of the small unit grid diffusion installation process includes:

[0114] a. Assemble the first small unit space frame, which includes a sphere, a chord, and two web members, on the ground. Hoist the first small unit space frame to the installation position and manually assemble the first small unit space frame with the corresponding space frame.

[0115] b. Assemble the second small unit space frame, which includes a sphere, two chords and two web members, on the ground. Hoist the second small unit space frame to the installation position and manually assemble the second small unit space frame with the corresponding space frame.

[0116] c. Assemble the third small unit space frame, which includes a sphere, a chord, and two web members, on the ground. Hoist the third small unit space frame to the installation position and manually assemble the third small unit space frame with the corresponding space frame.

[0117] d. Assemble the fourth small unit space frame, which includes a sphere, two chords and one web member, on the ground. Hoist the fourth small unit space frame to the installation position and manually assemble the fourth small unit space frame with the corresponding space frame.

[0118] Figures 12 to 15 This is a schematic diagram of the installation process for the small unit grid diffusion installation in step (5).

[0119] In this embodiment, the maximum combined weight of the small unit grid structure does not exceed 500KG.

[0120] During the dispersal process of the small unit space frame in step (7) towards the second gable wall space frame, it will be fixed with the corresponding support, and temporary support and wind ropes will be installed.

[0121] In step (9), the second arched side grid frame assembled on the ground needs to be lifted by two 75-ton cranes, with a total lifting weight of 16.48 tons.

[0122] In step (9), when the second arched side space frame crosses the belt conveyor during hoisting, the second arched side space frame needs to be temporarily supported. The support can be provided by using sleeper pads or by using steel pipes as temporary support pipes.

[0123] In step (9), the second arched side space frame needs to be slightly offset from the outside of the current axis when it is assembled on the ground to ensure that it does not affect the crane station position and the installation of the second arched side space frame when crossing the belt conveyor; at the same time, after the second arched side space frame is hoisted into place, it needs to be connected to the third gable wall space frame immediately, and the crane hook is released after the connection is completed.

[0124] Figure 21 This is a schematic diagram of the construction process of the second arched side space frame in step (9). Figure 22 This is a schematic diagram showing the completion of the installation of the second arched side space frame in step (9).

[0125] In this embodiment, the unit weight of the third gable wall space frame is 6.44 tons, the hoisting height is 20.4 meters, and the hoisting radius is 11 meters. Considering a safety factor of 1.3, a 50-ton mobile crane is used for hoisting.

[0126] The first, second, and third gable space frames all start independently, and then small unit space frames are installed in a dispersed manner to both sides. The above steps are repeated until the gable space frame is completely connected with the arched part of the space frame. After the connection is completed, the entire gable space frame is connected in a U-shape and has higher stability.

[0127] Step (10) The gable space frame continues to spread the small unit space frame upwards using the bulk method until the gable space frame and the arched part space frame are completely closed. During this process, supports are added to both sides of the arched part space frame to ensure that there are more than two continuous supports on both sides of the arched part space frame, thereby increasing the stability of the structure.

[0128] Figure 23 This is a schematic diagram of the structure in step (10) where the gable wall space frame and the arched part of the space frame are fully joined together.

[0129] In this embodiment, the arched portion of the space frame in step (11) is installed in a loose, stepped manner to diffuse the small unit space frame towards the axial side.

[0130] In step (11), the small unit space frame is diffused and installed on both sides of the axis in the arched part of the space frame. The cantilever high-altitude bulk installation method is adopted to ensure the stability coefficient and spatial stiffness. It can effectively bear asymmetric loads, concentrated loads and dynamic loads, and has good seismic performance.

[0131] Figure 24 This is a schematic diagram of the installation process of filling the filler rod in step (13). Example

[0132] This embodiment differs from Embodiment 1 in that, in this embodiment, the arched portion of the space frame in step (11) is installed in a manner of one row of upper chords and one row of lower chords towards the side of the axis to diffuse the small unit space frame.

[0133] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to achieve substantially the same technical effect are all covered within the protection scope of the present invention.

Then, the second arched side space frame, which has been assembled on the ground, will be hoisted to the installation position and connected with the third gable wall space frame; steel wire ropes will be used to stabilize the structure; when assembling the second arched side space frame on the ground, it needs to be slightly offset to the outside of the current axis to ensure that it does not affect the crane position and the installation of the second arched side space frame when crossing the belt conveyor; at the same time, after the second arched side space frame is hoisted into place, it needs to be connected to the third gable wall space frame immediately, and the crane hook will be released after the connection is completed; (10) The first gable wall space frame, the second gable wall space frame and the third gable wall space frame that are connected to each other form a gable wall space frame on the same axis; The gable space frame continues to expand upwards using a piecemeal method to install smaller unit space frames until the gable space frame is completely closed with the first arched side space frame and the second arched side space frame; (11) After the first arched side space frame and the second arched side space frame are joined together, they form the arched part of the gable space frame. After the gable space frames on both sides of the current axis are joined together, the arched part of the space frame is installed in a diffused manner towards both sides of the axis as small unit space frames. (12) After the small unit space frame is installed between the arched parts of the gable space frame on multiple axes, the expansion joints between them are connected and transitioned by ordinary mesh rods. (13) Remove the temporary connecting rods and fill the missing parts of the gable wall space frame with rods; after the filling and replacement of rods are completed, the gable wall space frame is installed as a whole.

2. The method for constructing a gable wall space frame according to claim 1, characterized in that: Before assembling the medium and small unit space frames in the assembly area, the ground in the assembly area will be laid with sleepers or steel pipes, and a level will be used to measure and level it. If there are differences in elevation during the measurement, steel plates will be used for fine adjustment.

3.
