Scaffold assembly and method of installing scaffold assembly

[0001] Cross-reference to Related Applications

[0002] The present application claims priority to the Chinese patent application No. 202410893588.1, filed on July 04, 2024, and entitled "Scaffold assembly and method of installing scaffold assembly", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of scaffold construction, and in particular to a scaffold assembly and a method of installing the scaffold assembly. BACKGROUND

[0004] Scaffold devices such as scaffolds are usually formed by interconnecting a plurality of horizontal poles, a plurality of vertical poles, and a plurality of diagonal poles. When the scaffold is built, the horizontal poles, the vertical poles, and the diagonal poles are connected by disc clamps or pin joints.

[0005] Based on the connection mode of the disc clamps and the pin joints, the horizontal poles, the vertical poles, and the diagonal poles are connected one by one from bottom to top by manual work when the scaffold device such as the scaffold is built. This not only has low construction efficiency and high labor intensity, but also greatly increases the risk of high-altitude work in the later stage of construction.

[0032] In a second aspect, the disclosure provides a support assembly installation method, which applies the support assembly of any one of the preceding embodiments, and includes:

[0033] S1: divide the periphery of each bracket unit into front side, rear side, left side and right side, and take one side of the first mounting side and the second mounting side of each bracket unit as the top side and the other side as the bottom side; a plurality of bracket units are arranged in the horizontal direction on the rear side of one of the bracket units;

[0034] S2: a plurality of bracket units are arranged in order from bottom to top above each bracket unit, or, one bracket unit is arranged on the right side of each bracket unit first, and then a plurality of bracket units are alternately arranged above each group of two bracket units adjacent to each other in the left and right directions; meanwhile, any two bracket units adjacent to each other in the up and down directions in each group are connected to each other through the plug-in part and the counter plug hole, and the plug-in parts of any two bracket units adjacent to each other in the horizontal direction in each group are connected to each other through the limiting pin and the limiting slot;

[0035] S3: one bracket unit is arranged on the right side of each bracket unit with space on the right side, meanwhile, each group of two bracket units adjacent to each other in the up and down directions are connected to each other through the plug-in part and the counter plug hole, and the plug-in parts of each group of two bracket units adjacent to each other in the horizontal direction are connected to each other through the limiting pin and the limiting slot;

[0036] S4: repeat step S3 until all the bracket units are connected in order to form the bracket assembly.

[0037] In the optional embodiment, in steps S2-S4, when one bracket unit is arranged above another bracket unit, a forklift is used to install the bracket unit on the top side of the bracket unit below.

[0038] The support assembly provided by the present disclosure comprises a plurality of support units; each support unit comprises a first mounting side and a second mounting side opposite to each other, the first mounting side is provided with a plug-in part, and the second mounting side is provided with a counter plug-in hole; the plug-in part is configured to be plugged into the counter plug-in hole on the other support unit on one side of the first mounting side, and the counter plug-in hole is configured to be plugged into the plug-in part on the other support unit on one side of the second mounting side; the support unit further comprises a peripheral side between the first mounting side and the second mounting side, the peripheral side of the plug-in part is provided with a limiting pin and a limiting groove; the limiting pin is configured to be plugged into the limiting groove on the other support unit on the peripheral side of the support unit where the limiting pin is located when the plug-in part where the limiting pin is located is plugged into the counter plug-in hole on the other support unit; the limiting groove is configured to be plugged into the limiting pin on the other support unit on the peripheral side of the support unit where the limiting groove is located when the plug-in part where the limiting groove is located is plugged into the counter plug-in hole on the other support unit; the plugging direction between the limiting pin and the limiting groove is the same as the plugging direction between the plug-in part and the counter plug-in hole, and the limiting pin and the limiting groove can abut against each other in a direction perpendicular to the plugging direction after being plugged into each other. The support assembly provided by the present disclosure can be used as a scaffold in a construction project. Before the support assembly is installed, a sufficient number of support units can be manufactured on the ground in advance, and then a plurality of support units can be sequentially transported to the support assembly erection site. After the support units are transported to the erection site, the first mounting side or the second mounting side of the support units needs to be upward, and then a plurality of other support units can be sequentially stacked above one of the support units, and during the stacking process, the plug-in part and the counter plug-in hole are used to plug the two adjacent support units above and below into each other. Then a plurality of support units can be sequentially stacked and plugged from bottom to top on the peripheral side of the stacked plurality of support units, and during the process of stacking and plugging other support units above each support unit, the limiting pin and the limiting groove between the support unit above and the other support units on the peripheral side of the support unit are plugged into each other. Since the plugging direction between the limiting pin and the limiting groove is the same as the plugging direction between the plug-in part and the counter plug-in hole, the limiting pin and the limiting groove between the two adjacent support units above and below are aligned vertically before the other support units are stacked and plugged above each support unit, so that the limiting pin and the limiting pin are plugged into each other during the stacking and plugging, without the need for additional plugging operation. Since the limiting pin and the limiting groove can abut against each other in a direction perpendicular to the plugging direction after being plugged into each other, the limiting pin and the limiting groove can be used to lock the support unit above and the other support units on the peripheral side of the support unit after the two adjacent support units are stacked and plugged, and then the support unit below and the other support units on the peripheral side of the support unit can also be locked. By repeating the above process, all support units can be plugged and locked in sequence to form a stable support assembly.It can be seen that the support assembly provided by the present disclosure only needs to align and stack the support units from bottom to top in the installation process, and does not need to use fasteners or pin connectors to connect the support units. Since the stacking and inserting process of the support units is relatively simple, the process can be realized by using mechanical equipment such as forklifts and cranes, and manual inserting operation is not required, thereby effectively improving construction efficiency, reducing manual labor intensity, and effectively reducing the risk of manual high-altitude operation in the late installation stage.

[0039] The support assembly provided by the present disclosure can realize the insertion and locking between the support units by stacking and inserting multiple support units from bottom to top, repeatedly stacking and inserting multiple support units from bottom to top around the side of the stacked support units, and inserting the limiting pin and the limiting slot between every two support units adjacent in the horizontal direction during the stacking process, thereby forming a support assembly with stable structure. Based on this, the installation process of the support assembly provided by the present disclosure can be realized by using mechanical equipment such as forklifts, and manual assembly is not required, thereby effectively improving construction efficiency, reducing manual labor intensity, and reducing the risk of manual high-altitude operation.

[0040] The support assembly installation method provided by the present disclosure applies the above support assembly, and includes the following steps: S1: dividing the side of each support unit into front side, rear side, left side and right side, and taking one side of the first installation side and the second installation side of each support unit as the top side and the other side as the bottom side; arranging one support unit on the right side of one of the support units, and / or arranging multiple support units in sequence on the rear side of one of the support units in the horizontal direction and arranging one support unit on the right side of each support unit; S2: stacking and arranging multiple support units in sequence from bottom to top above each support unit, simultaneously inserting any two support units adjacent in the vertical direction into each other through the insertion part and the counter insertion hole, and connecting the insertion parts of any two support units adjacent in the horizontal direction through the limiting pin and the limiting slot; S3: arranging one support unit on the right side of each support unit with space on the right side, simultaneously inserting each two support units adjacent in the vertical direction into each other through the insertion part and the counter insertion hole, and connecting the insertion parts of each two support units adjacent in the horizontal direction through the limiting pin and the limiting slot; and S4: repeating step S3 until all support units are connected in sequence to form a support assembly.

[0041] The support assembly installation method provided by the present disclosure applies the above support assembly, and after steps S1-S4, the support units can also be stacked and inserted to form a support assembly with stable structure. Based on this, the support assembly installation method can also realize the installation process of the support assembly by using mechanical equipment such as forklifts, and manual assembly is not required, thereby effectively improving construction efficiency, reducing manual labor intensity, and reducing the risk of manual high-altitude operation.

[0071] In order to make the purposes, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure but not all the embodiments. The components of the embodiments of the present disclosure described and shown in the drawings can be arranged and designed in various different configurations.

[0072] Therefore, the following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the claimed present disclosure, but only represents selected embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present disclosure.

[0073] Some embodiments of the present disclosure will be described in detail below with reference to the drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0074] Embodiments:

[0075] As shown in FIGS. 1, 2 and 3, the support assembly provided by the present embodiment comprises a plurality of support units 1; each support unit 1 comprises a first mounting side and a second mounting side opposite to each other, as shown in FIGS. 1 and 4, the first mounting side is provided with a plug-in part 10, as shown in FIGS. 4 and 8, the second mounting side is provided with a counter plug hole 11; the plug-in part 10 is configured to be plugged with the counter plug hole 11 on the other support unit 1 on the side of the first mounting side, and the counter plug hole 11 is configured to be plugged with the plug-in part 10 on the other support unit 1 on the side of the second mounting side; the support unit 1 further comprises a peripheral side between the first mounting side and the second mounting side, as shown in FIGS. 4, 5, 6 and 7, the peripheral side of the plug-in part 10 is provided with a limiting pin 100 and a limiting groove 101; the limiting pin 100 is configured to be plugged with the limiting groove 101 on the other support unit 1 on the peripheral side of the support unit 1 when the plug-in part 10 where the limiting pin 100 is located is plugged with the counter plug hole 11 on the other support unit 1; the limiting groove 101 is configured to be plugged with the limiting pin 100 on the other support unit 1 on the peripheral side of the support unit 1 when the plug-in part 10 where the limiting groove 101 is located is plugged with the counter plug hole 11 on the other support unit 1; the plugging direction between the limiting pin 100 and the limiting groove 101 is the same as the plugging direction between the plug-in part 10 and the counter plug hole 11, and the limiting pin 100 and the limiting groove 101 can abut each other in a direction perpendicular to the plugging direction after being plugged, so as to limit the support unit 1 and the other support unit 1 on the peripheral side of the support unit 1 from separating from each other along the peripheral direction.

[0076] The support assembly provided by the embodiment can be used as a scaffold in a construction project. Before the support assembly is installed, a sufficient number of support units 1 shown in FIG. 1 can be manufactured on the ground in advance, and then the support units 1 are sequentially transported to a support assembly erection site. After the support units 1 are transported to the erection site, the first installation side or the second installation side of the support unit 1 is made to face upward, and then a plurality of other support units 1 can be sequentially stacked above one of the support units 1, and in the stacking process, the plug-in part 10 and the counter plug-in hole 11 are used to make the two adjacent support units 1 above and below be plugged in with each other, as shown in FIG. 4. Then, a plurality of support units 1 can be sequentially stacked and plugged in from bottom to top at the circumferential side of the stacked support units 1, and in the process of stacking and plugging in the other support units 1 above each support unit 1, the limiting pin 100 and the limiting groove 101 between the support unit 1 above and the other support units 1 located at the circumferential side of the support unit 1 above are plugged in with each other, as shown in FIGS. 5, 6 and 7.

[0077] Since the plugging-in direction between the limiting pin 100 and the limiting groove 101 is the same as the plugging-in direction between the plug-in part 10 and the counter plug-in hole 11, before the other support units 1 are stacked and plugged in above each support unit 1, the limiting pin 100 and the limiting groove 101 between the two adjacent support units 1 above and below are aligned vertically, so that the limiting pin 100 and the limiting pin 100 are plugged in with each other at the same time of the stacking and plugging in, and there is no need to additionally perform the plugging-in operation. Since the limiting pin 100 and the limiting groove 101 are plugged in and can abut against each other in a direction perpendicular to the plugging-in direction, after the two adjacent support units 1 are stacked and plugged in, the limiting pin 100 and the limiting groove 101 can be used to lock the support unit 1 above and the other support units 1 located at the circumferential side of the support unit 1 above with each other, and then the support unit 1 below and the other support units 1 located at the circumferential side of the support unit 1 below can also be locked with each other, as shown in FIGS. 6 and 7.

[0078] The above process is repeated, so that all the support units 1 are plugged in and sequentially locked, thereby forming a support assembly with stable structure.

[0079] As can be seen, the support assembly provided by the embodiment only needs to be aligned and stacked and plugged in from bottom to top in the installation process, and there is no need to use fasteners or pin connectors to connect the support units 1. Since the stacking and plugging-in process of the support units 1 is relatively simple, the process can be realized by using the forklift 6 or the crane shown in FIG. 3 or other mechanical equipment, and there is no need for manual plugging-in operation, thereby effectively improving the construction efficiency and reducing the labor intensity. In the later stage of installation, the risk of manual high-altitude operation can also be effectively reduced.

[0080] It should be noted that, in order to accurately plug in the support units 1 by using the forklift 6 or other mechanical equipment to improve the construction efficiency, a camera device can be provided on the forklift 6 or other mechanical equipment.

[0081] The support assembly provided by the embodiment is formed by stacking and inserting multiple support units 1 from bottom to top, and repeatedly stacking and inserting multiple support units 1 from bottom to top around the side of the stacked support units 1, and inserting the limiting pin 100 and the limiting slot 101 between every two support units 1 adjacent in the horizontal direction during the stacking process, so that the support units 1 are inserted and locked, thereby forming a support assembly with stable structure. Therefore, the installation process of the support assembly provided by the embodiment can be realized by using mechanical equipment such as a forklift 6, without manual assembly, which can effectively improve the construction efficiency, reduce the labor intensity, and reduce the risk of high-altitude operation.

[0082] It should be noted that the mutual abutment of the limiting pin 100 and the limiting slot 101 after the insertion can be achieved by connecting a spring positioning pin or the like that can be extended and retracted vertically on the side of the limiting pin 100 away from the insertion part 10. Correspondingly, a clamping groove is provided at the position of the limiting slot 101 corresponding to the end of the spring positioning pin. After the spring positioning pin moves to the clamping groove, it can be extended and its end can be inserted into the clamping groove, thereby limiting the withdrawal of the limiting pin 100 from the limiting slot 101.

[0083] Alternatively, in order to achieve the mutual abutment of the limiting pin 100 and the limiting slot 101 after the insertion, as shown in FIGS. 4-7, the insertion part 10 can be tubular, and the side of the limiting pin 100 away from the insertion part 10 is provided with an abutting protrusion 1000, and the limiting slot 101 communicates with the inner space of the tubular insertion part 10. The abutting protrusion 1000 is configured to abut with the inner wall of the insertion part 10 where the limiting slot 101 is located after the insertion of the limiting pin 100 and the limiting slot 101.

[0084] As can be seen from FIG. 5, while the insertion part 10 and the counter insertion hole 11 of the two support units 1 adjacent above and below are inserted, the limiting pin 100 and the limiting slot 101 between the upper support unit 1 and the support unit 1 around the side thereof are also inserted, and after the insertion of the limiting pin 100 and the limiting slot 101, the separation of the upper support unit 1 and the support unit 1 around the side thereof in the circumferential direction is limited, thereby locking the upper support unit 1 and the support unit 1 around the side thereof.

[0085] It should be noted that, as shown in FIGS. 5 and 6, when the upper support unit 1 and the lower support unit 1 are provided with other support units 1 on the circumferential side of the upper support unit 1 and the circumferential side of the lower support unit 1, and the upper support unit 1 and the lower support unit 1 are inserted into each other, and the other support units 1 on the circumferential side of the upper support unit 1 and the other support units 1 on the circumferential side of the lower support unit 1 are inserted into each other, when the upper support unit 1 and the other support units 1 on the circumferential side thereof are locked with each other through the limiting pin 100 and the limiting groove 101, the support units 1 will be sequentially locked with each other, thereby achieving the locking of the support units 1 after being inserted, so that the support assembly can be kept stable at any time during the installation process.

[0086] To improve the abutting stability between the abutting protrusion 1000 and the inner wall of the insertion part 10, the abutting protrusion 1000 is optionally an arc surface plate, and the arc surface plate can be fitted with the inner wall of the insertion part 10.

[0087] Optionally, as shown in FIGS. 6 and 7, the number of the limiting pins 100 and the limiting grooves 101 on the insertion part 10 is multiple, the multiple limiting pins 100 and the multiple limiting grooves 101 are sequentially and equally spaced along the circumferential direction of the insertion part 10, and the multiple limiting pins 100 are arranged in pairs, and the multiple limiting grooves 101 are arranged in pairs.

[0088] When the number of the limiting pins 100 and the limiting grooves 101 is multiple and they are sequentially and equally spaced along the circumferential direction of the insertion part 10, not only can the structure of the support unit 1 be unified, but also the installation convenience of the support assembly can be improved, and the stress balance of the support unit 1 can be improved, thereby effectively improving the installation balance and the installation stability of the support assembly.

[0089] Since the circumferential side of each support unit 1 is connected with at most four other support units 1 during the installation of the support assembly, the number of the limiting pins 100 and the limiting grooves 101 on the insertion part 10 in the embodiment is two, and the two limiting pins 100 and the two limiting grooves 101 are configured to be connected with the four other support units 1.

[0090] In the embodiment, the first installation side can be the bottom side of the support unit 1, and the second installation side can be the top side of the support unit 1.

[0091] When the first installation side is the bottom side of the support unit 1, the insertion part 10 can be located at the bottom of the support unit 1, and the insertion hole 11 can be located at the top of the support unit 1. This arrangement can facilitate the insertion of the upper support unit 1 into the lower support unit 1 during the vertical stacking of the support units 1, and can facilitate the detachment of the upper support unit 1 from the lower support unit 1 during the disassembly of the support assembly.

[0092] In the embodiment, the support unit 1 can also be formed by connecting various rods. In order to facilitate the plugging process between the plugging part 10 and the counter-plugging hole 11, as shown in FIG. 1, a sleeve 110 shown in FIG. 8 can be sleeved on the end of the rod at the second mounting side of the support unit 1. The internal space of the sleeve 110 forms the counter-plugging hole 11.

[0093] Optionally, as shown in FIG. 8, a partition plate 1100 can be arranged inside the sleeve 110. The partition plate 1100 is configured to divide the counter-plugging hole 11 into two counter-plugging slots with the same volume and opposite openings. The counter-plugging slot with the upward opening is configured to be plugged with the plugging part 10 of the support unit 1 located above it, and the counter-plugging slot with the downward opening is configured to be plugged with the plugging part 10 of the support unit 1 located below it.

[0094] It can be seen that the partition plate 1100 in the sleeve 110 can effectively improve the plugging stability and balance between the support units 1.

[0095] As shown in FIG. 9, the support assembly provided in the embodiment further comprises a top support structure 2. Among the plurality of support units 1, the top side of the support unit 1 located at the top is provided with a threaded hole 3, and the top support structure 2 is provided with an external thread matched with the threaded hole 3. The top support structure 2 is threadedly connected in the threaded hole 3.

[0096] The top support structure 2 is configured to be mounted on the uppermost of the stacked support units 1 after the support units 1 are stacked and plugged. The top of the top support structure 2 is configured to support beams, walking plates and other components.

[0097] It should be noted that the top support structure 2 and the support unit 1 located at the top are connected through the threaded hole 3 and the external thread, which can be achieved by manual high-altitude operation. Compared with the situation that the entire support assembly installation process relies on manual assembly, only the connection between the top support structure 2 and the support unit 1 relies on manual operation, which can still improve the construction efficiency and reduce the labor intensity.

[0098] As shown in FIGS. 10 and 11, the support assembly provided in the embodiment further comprises a rotation limiting piece 4. Each thread of the external thread is provided with a notch, and a plurality of notches are located on the same straight line to form a first discontinuous channel 5 extending in the axial direction of the external thread on the top support structure 2. Each thread of the threaded hole 3 is provided with a break, and a plurality of breaks are located on the same straight line to form a second discontinuous channel extending in the axial direction of the threaded hole 3 on the inner wall of the threaded hole 3. The first discontinuous channel 5 on the top support structure 2 is configured to communicate with the second discontinuous channel in the threaded hole 3 to form an anti-rotation groove when the top support structure 2 is threadedly connected in the threaded hole 3. The rotation limiting piece 4 is plugged into the anti-rotation groove in the extension direction of the first discontinuous channel 5.

[0099] In the installation process, the top support structure 2 can be first threaded into the threaded hole 3 of the top support unit 1, and the first intermittent channel 5 on the top support structure 2 is communicated with the second intermittent channel in the threaded hole 3 to form an anti-rotation groove. Then, the rotation limiting piece 4 shown in FIG. 10 can be inserted into the anti-rotation groove. At this time, as shown in FIG. 11, the rotation limiting piece 4 can abut between the threads on both sides of the first intermittent channel 5 on the top support structure 2 and between the threads on both sides of the second intermittent channel on the threaded hole 3, thereby limiting the continuous rotation or reverse rotation of the top support structure 2 in the threaded hole 3, and effectively preventing the top support structure 2 from being withdrawn from the threaded hole 3.

[0100] In order to facilitate the insertion and withdrawal of the rotation limiting piece 4 into / from the anti-rotation groove, as shown in FIG. 10, the rotation limiting piece 4 can include a plug rod configured to be inserted into the anti-rotation groove and a handle rod connected perpendicularly to one side of the plug rod. The handle rod can abut against the top side of the top support unit 1, and can not only serve as a handle, but also prevent the plug rod from being withdrawn from the anti-rotation groove due to sinking into the anti-rotation groove.

[0101] As shown in FIGS. 12-17, the support unit 1 includes a folding frame 12 and a strut structure 13. As shown in FIGS. 12 and 15, the folding frame 12 can be folded and unfolded, and as shown in FIG. 1, the strut structure 13 is configured to be detachably connected between opposite sides of the folding frame 12 after the folding frame 12 is unfolded, so as to limit the folding of the folding frame 12.

[0102] Compared with the fixed support unit 1, the support unit 1 including the folding frame 12 can effectively reduce the occupied space of the support unit 1 during transportation and storage, and effectively improve the transportation convenience of the support unit 1. Therefore, the support unit 1 of the present embodiment includes the folding frame 12 and the strut structure 13, wherein the strut structure 13 can support the folding frame 12 after the folding frame 12 is unfolded, so as to prevent the folding of the folding frame 12, thereby improving the structural stability of the support unit 1 during installation of the support assembly.

[0103] In order to improve the connection convenience between the strut structure 13 and the folding frame 12, the strut structure 13 and the folding frame 12 can be detachably connected through the plug-in mode.

[0104] Optionally, as shown in FIG. 15, the folding frame 12 comprises a plurality of vertical rod structures 120 and a plurality of foldable horizontal rod structures 121, the plurality of horizontal rod structures 121 are sequentially and spacedly arranged, the plurality of vertical rod structures 120 are sequentially and circumferentially distributed along the horizontal rod structures 121, and each vertical rod structure 120 is sequentially connected with the plurality of horizontal rod structures 121; as shown in FIG. 1, FIG. 20 and FIG. 23, the supporting rod structure 13 comprises a plurality of horizontal rods 130 and a plurality of inclined rods 131, the plurality of horizontal rods 130 are configured to be correspondingly inserted between each two adjacent vertical rod structures 120 after the folding frame 12 is unfolded, and the plurality of inclined rods 131 are configured to be correspondingly inserted between each two adjacent vertical rod structures 120 after the folding frame 12 is unfolded.

[0105] In order to realize the folding and unfolding of the folding frame 12, the vertical rod structure 120 and the horizontal rod structure 121 in the folding frame 12 can be hingedly connected with each other. As shown in FIG. 13, the top and bottom of the vertical rod structure 120 are respectively provided with a hinge lug 1200, and as shown in FIG. 16, the two ends of each horizontal rod structure 121 are respectively hingedly connected with the hinge lug 1200.

[0106] In addition, as shown in FIG. 15, the horizontal rod structure 121 can comprise a plurality of horizontal rods 1210, each of which comprises two rod segments, one end of which is hingedly connected with each other; the horizontal rod structure 121 can also comprise a hinge piece 1211 as shown in FIG. 14, and the hinge pieces 1211 are hingedly connected with the hinge connection portions of the plurality of horizontal rods 1210 in the horizontal rod structure 121.

[0107] When the folding frame 12 is folded, as shown in FIG. 12, the two rod segments of the horizontal rod 1210 rotate towards each other with the hinge piece 1211 as the rotation center, thereby realizing the folding of the horizontal rod 1210; at the same time, the end of the horizontal rod structure 121 rotates towards the vertical rod structure 120 with the hinge lug 1200 as the rotation center, thereby realizing the folding between the horizontal rod structure 121 and the vertical rod structure 120, until the folding frame 12 is folded to the state shown in FIG. 12. When the folding frame 12 is unfolded, the two rod segments of the horizontal rod 1210 and the horizontal rod structure 121 are respectively rotated in the opposite direction, thereby unfolding the horizontal rod 1210 and unfolding the horizontal rod structure 121 relative to the vertical rod structure 120, until the folding frame 12 is unfolded to the state shown in FIG. 15.

[0108] In order to realize the insertion between the horizontal rod 130 and the vertical rod structure 120 and the insertion between the inclined rod 131 and the vertical rod structure 120, as shown in FIG. 16, the hinge lug 1200 on the vertical rod structure 120 can be provided with a plurality of insertion slots spacedly distributed along the circumference thereof; correspondingly, as shown in FIG. 21 and FIG. 22, the two ends of the inclined rod 131 are respectively provided with an insertion pin 132 matched with the insertion slot, and as shown in FIG. 24, the two ends of the horizontal rod 130 are respectively provided with an insertion pin 132 matched with the insertion slot.

[0109] When the cross bar 130 is inserted into the vertical rod structure 120, as shown in FIG. 18, the pins 132 on the cross bar 130 can be inserted into the partial insertion slots on the hinged lug plate 1200 in the vertical direction; when the inclined bar 131 is inserted into the vertical rod structure 120, as shown in FIG. 19, the pins 132 on the inclined bar 131 can be inserted into the remaining insertion slots on the hinged lug plate 1200 in the vertical direction.

[0110] The embodiment also provides a support assembly installation method, which applies the above support assembly. As shown in FIG. 25, the support assembly installation method comprises the following steps:

[0111] Step S1: dividing the circumferential side of each support unit 1 into a front side, a rear side, a left side and a right side, and taking one side of the first mounting side and the second mounting side of each support unit 1 as a top side and the other side as a bottom side; sequentially arranging a plurality of support units 1 on the rear side of one of the support units 1 in the horizontal direction;

[0112] Step S2: sequentially stacking a plurality of support units 1 above each support unit 1 from bottom to top, or first arranging one support unit 1 on the right side of each support unit 1, and then alternately stacking a plurality of support units 1 above each group of two support units 1 adjacent to each other in the left and right directions; simultaneously inserting any group of two support units 1 adjacent to each other in the vertical direction into each other through the insertion part 10 and the counter insertion hole 11, and connecting the insertion parts 10 of any group of two support units 1 adjacent to each other in the horizontal direction to each other through the limiting pin 100 and the limiting slot 101;

[0113] Step S3: arranging one support unit 1 on the right side of each support unit 1 with space on the right side, and simultaneously inserting each group of two support units 1 adjacent to each other in the vertical direction into each other through the insertion part 10 and the counter insertion hole 11, and connecting the insertion parts 10 of each group of two support units 1 adjacent to each other in the horizontal direction to each other through the limiting pin 100 and the limiting slot 101;

[0114] Step S4: repeating step S3 until all support units 1 are sequentially connected to form a support assembly.

[0115] The support assembly installation method provided by the embodiment applies the above support assembly. After steps S1-S4, the support units 1 can also be stacked and inserted to form a support assembly with stable structure. Therefore, the support assembly installation method can also use mechanical equipment such as a forklift 6 to install the support assembly, without manual assembly, thereby effectively improving construction efficiency, reducing labor intensity and reducing the risk of manual high-altitude operation.

[0116] It should be noted that in step S2, if only a plurality of support units 1 are sequentially stacked from bottom to top above each support unit 1, at this time the support units 1 will be inserted and connected from bottom to top to form a single-row support wall, and the front and rear adjacent two support units 1 in the support wall can be locked with each other through the limiting groove 101 and the limiting pin 100, thereby ensuring the stability of the wall body of the support wall, but the left and right stability of the support wall is difficult to guarantee, and thus the ground anchor can be arranged at the bottom of the bottommost support unit 1 of the support wall, and the bottommost support unit 1 is stably fixed to the ground through the ground anchor. After step S2 is completed, steps S3 and S4 are sequentially performed, and after steps S2-S4 are completed, the arrangement order of each unit in the support assembly is shown in FIG. 26, wherein the serial numbers ①-⑩ in FIG. 26 respectively represent the installation order of the support unit 1 corresponding to the serial number in the installation process, and taking a single-row support wall including five layers of support units 1 as an example, the support units 1 corresponding to the serial numbers ①-⑤ are installed in step S2, the support units 1 corresponding to the serial numbers ⑥-⑩ are installed in step S3, the support units 1 corresponding to the serial numbers ⑪-⑩ are installed in step S4 when step S3 is repeated for the first time, the support units 1 corresponding to the serial numbers ⑪-⑩ are installed in step S4 when step S3 is repeated for the second time, and so on. The installation process of all support units 1 in the support assembly can be sequentially completed.

[0117] In step S2, if one support unit 1 is arranged on the right side of each support unit 1 as shown in FIG. 2, and then a plurality of support units 1 are alternately and sequentially stacked above each group of left and right adjacent two support units 1, at this time the support units 1 will be alternately and sequentially inserted and connected from bottom to top to form two rows of support walls, and the front and rear adjacent two support units 1 in each row of support walls can be locked with each other through the limiting groove 101 and the limiting pin 100, thereby ensuring the stability of the wall body of each row of support walls. At the same time, the left and right two rows of support walls can also be locked with each other through the limiting groove 101 and the limiting pin 100, thereby supporting each other to simultaneously ensure the stability of the two rows of support walls, and the ground anchor is not needed for reinforcement. After step S2 is completed, steps S3 and S4 are sequentially performed, and after steps S2-S4 are completed, the arrangement order of each unit in the support assembly is shown in FIG. 27, wherein the serial numbers ①-⑩ in FIG. 27 respectively represent the installation order of the support unit 1 corresponding to the serial number in the installation process, and taking each row of support walls including five layers of support units 1 as an example, the support units 1 corresponding to the serial numbers ①-⑩ are installed in step S2 in the left-right alternating and sequential order, the support units 1 corresponding to the serial numbers ⑪-⑩ are installed in step S3, the support units 1 corresponding to the serial numbers ⑪-⑩ are installed in step S4 when step S3 is repeated for the first time, the support units 1 corresponding to the serial numbers ⑪-⑩ are installed in step S4 when step S3 is repeated for the second time, and so on. The installation process of all support units 1 in the support assembly can be sequentially completed. ​​​​​The corresponding support unit 1 is completed in step S4 when step S3 is repeated for the first time, and in the same way, the layering installation process of all support units 1 in the support assembly can be sequentially completed.

[0118] It can be seen that step S3 is to erect a single-row support wall on the right side of the single-row support wall or the left and right two-row support walls in step S2, and step S4 is to repeat the erection of a single-row support wall on the rightmost side of all the erected support walls, thereby gradually increasing the number of rows of support walls until the installation process of all support units 1 is completed.

[0119] Since the forklift 6 is more convenient than the crane and other mechanical equipment, when a support unit 1 is stacked above in steps S2-S4, the forklift 6 is used to install the support unit 1 above on the top side of the support unit 1 below.

[0120] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present disclosure, but not to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent replacements for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure. Industrial applicability

[0121] During the installation process of the support assembly of the present disclosure, mechanical equipment such as a forklift can be used, and manual assembly is not required, which not only effectively improves the construction efficiency and reduces the labor intensity, but also reduces the risk of manual high-altitude work.
