[0032] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0033] Please refer to Figure 1-4 , the present invention provides an assembled building structural member, including a bottom beam 1, including two parallel and spaced apart; The swing beam 2 is arranged one-to-one with the bottom beam 1, one end of which is hingedly connected to the bottom beam 1, and the axis of the hinged part extends along the spacing direction of the two bottom beams; A power telescopic rod 4, both ends of which are respectively hinged to the bottom beam 1 and the swing beam 2; A bearing plate 27 is disposed between the two swing beams 2 and close to one end of the bottom beam 1 , and an upper limit assembly 3 is disposed at the other end. The upper surface of the bearing plate 27 is perpendicular to the extension direction of the swing beam 2 .

[0034] Specifically, the bottom beam 1 is provided with a first hinge 10 and a second hinge 11, a hinge shaft 21 is provided on the outer side surface of the bottom end of the swing beam 2, the swing beam 2 is hingedly connected to the second hinge 11 through the hinge shaft 21, and a third hinge 20 is provided on the outer side surface of the middle area of ​​the swing beam 2, and both ends of the power telescopic rod 4 are respectively hingedly connected to the first hinge and the second hinge. Specifically, the first hinge, the second hinge and the third hinge all adopt a lug structure, and the hinge axes of the three hinges are parallel. The power telescopic rod 4 can be any one of an electric telescopic rod, a pneumatic telescopic rod and a hydraulic telescopic rod. When working, the extension and retraction of the power telescopic rod 4 can push the swing beam to swing around the hinge shaft 21, so that the swing beam can be moved. Figure 1 , Figure 2 The bottom beam 2 is switched between the inclined state shown in the figure and the vertical state in which the swing beam is perpendicular to the bottom beam. When in use, the two bottom beams 1 are set on both sides of the wall to be assembled, and the hinge shaft 21 corresponds to the position of the assembled wall. The bottom beam can be set on the beam or floor below, and ensure that the bottom beam is in a horizontal state and the two bottom beams are at the same height. Then the bottom beam is fixed, and the elongation of the power telescopic rod 4 is controlled to make the swing beam 2 in Figure 1 , Figure 2 In the inclined state shown, a crane is used to lift the wall to be assembled above the assembly position, and then it is gradually lowered, and the lower end of the wall is set on the load-bearing plate 27, and then it continues to fall. At this time, the workers cooperate to make the wall tilt against the swing beam 2, and make the wall surface of the wall flush with the side of the swing beam away from the power telescopic rod, and limit the upper end of the wall by the upper limit assembly, and then remove the hook of the crane, control the extension of the power telescopic rod 4, push the swing beam 2 to swing to a vertical state, swing the wall to a vertical state, and then use diagonal rods and other fixing devices to fix the wall to complete the assembly. In this way, the assembly and installation efficiency of the wall can be improved, and the labor intensity of the workers can be reduced.

[0035] Furthermore, as a specific implementation, a second power telescopic rod 9 is provided at both ends of each bottom beam 1, and the second power telescopic rod is arranged perpendicular to the bottom beam. The lower end portion of the second power telescopic rod can extend out of the lower surface of the bottom beam to support the bottom beam. By individually controlling the extension and retraction of each second power telescopic rod 9, the bottom beam can be horizontally adjusted, and after the wall installation is completed, the supporting force between the bearing plate 27 and the wall is reduced by controlling the contraction of the second power telescopic rod, and then the bottom beam is facilitated to move horizontally and separate from the wall. As a specific implementation, the second power telescopic rod is preferably a hydraulic telescopic rod.

[0036] Further, as a preferred embodiment, along the extension direction of the swing beam 2 , a first support member 23 is provided between the two swing beams 2 , and the bearing plate 27 includes two guide plates 27 which are slidably provided on the first support member 23 .

[0037] Specifically, refer to Figure 1-Figure 4 The first support member 23 is arranged between the two swing beams and the two ends are connected to the two swing beams. By setting two bearing plates 27 and slidingly cooperating with the guide of the first support member 23, the position of the bearing plate 27 can be adjusted to ensure that the bearing plate 27 is carried at a suitable position under the wall. The bearing plate 27 can be matched with the first support member 23 in any matching manner in the prior art as long as the adjustment purpose can be achieved. Specifically, a T-shaped guide member can be set on the lower side of the first support member 23, and the bearing plate 27 is provided with a T-shaped groove that slides with the guide of the T-shaped guide member. On the basis of achieving sliding cooperation, it can provide bearing capacity for the bearing plate 27.

[0038] Further, as a specific implementation method, refer to Figure 1-Figure 4 , and further includes a second support member 24 disposed between the two swing beams 2 and spaced apart from the first support member 23, wherein the swing beam 2, the first support member, and the second support member are on the same plane away from the surfaces of the power telescopic rod 4. Specifically, the first support member and the second support member are both rigid plates, the second support plate is disposed in the middle of the swing beam, and the upper surfaces of the first support member and the second support member are on the same plane as the surface of the swing beam. Through this arrangement, the first support member and the second support member can contact and position the wall surface together, provide support force to the wall, and ensure the positioning posture of the wall.

[0039] Furthermore, the upper limit assembly 3 is arranged on the side of the second support member 24 away from the first support member 23. Specifically, it should be noted that the length of the swing beam is greater than the height of the wall to be assembled, and the height of the wall to be assembled is greater than the distance from the bearing plate 27 to the second support member 24. By arranging the upper limit assembly 3 on the side of the second support member 24 away from the first support member 23, after the lower end of the wall to be assembled contacts the bearing plate 27 and leans against the first support member and the second support member, the upper limit assembly 3 is used to limit the upper end of the wall, so that the wall is limited by the upper limit assembly and the second support member 24 to ensure the stability of the limit. The specific structure of the upper limit assembly 3 is referred to below.

[0040] Further, as a preferred embodiment, refer to Figure 1-Figure 4 , Fig.14 Along the extension direction of the swing beam 2, the sides of the two swing beams 2 that are close to each other are both guided and movablely provided with a first sliding member 22, a first elastic member is provided between the first sliding member 22 and the swing beam 2, and both ends of the first support member 23 are connected to the two first sliding members 22, and the first elastic member can provide an elastic force to the first sliding member 22 toward the upper limit assembly 3.

[0041] Specifically, an internal space 28 is provided inside the swing beam, a first strip hole 201 communicating with the internal space 28 is provided on the side wall, the first sliding member 22 is guided and slidably provided in the internal space 28 and partially extends out of the first strip hole 201, and the end of the first support member 23 is fixedly connected to the first sliding member 22 by bolts, Fig.14 As a specific implementation, the first elastic member is a fifth compression spring 89 arranged between the bottom of the internal space 28 and the first sliding member. Through this arrangement, under normal conditions, the fifth compression spring 89 provides support force for the first sliding member under the action of the elastic force of the first compression spring 89, and the upper end of the first sliding member abuts against the upper end of the first strip hole 201. When the crane places the wall on the bearing plate 27, the fifth compression spring 89 can be compressed and buffered, thereby reducing the impact force on the bearing plate 27, reducing the impact force at the connection between the bearing plate 27 and the first support member 23, and improving the service life of the structure.

[0042] Further, as a preferred embodiment, refer to Figure 1-Figure 6 , Fig.14 Along the extension direction, the sides of the swing beams 2 that are close to each other are slidably provided with second sliding members 26, and the upper limit assembly 3 includes a rotating member whose two ends are respectively rotatably matched with the two second sliding members 26 and two limit plates 33 arranged at intervals on the rotating member.

[0043] Specifically, refer to Fig.14The swing beam is located at the upper end of the second support member 24 and is connected to the internal space 28 and is provided with a second strip hole 202. A second sliding member 26 is provided in the internal space 28 for guiding sliding. The two ends of the rotating member are rotatably matched with the two second sliding members 26. The upper limit assembly 3 includes Figure 1-Figure 3 In the initial state, the limit plate 33 is located on the side of the swing beam 2 close to the first power telescopic rod 4 and at the upper end of the swing beam 2. With this arrangement, the limit plate 33 will not hinder the upper surface of the swing beam, so it will not hinder when placing the wall. After the wall is placed on the bearing plate 27 and tilted against the swing beam 2, the rotating member is driven to move toward one end close to the bearing plate 27, and at the same time, the rotating member is driven to rotate around the axis, driving the limit plate 33 to rotate to the other side of the swing beam. When the plate surface of the bearing plate 27 is parallel to the upper surface of the swing beam, the rotating member stops rotating and continues to move. After the limit plate moves to the end of the wall, the bearing plate contacts the wall to limit the wall by moving the limit plate close to the wall. After limiting, the power telescopic rod 4 extends to drive the swing beam 2 to swing to a vertical state, and then fixes and supports the wall, and then controls the rotating member to move upward, return to the initial position, and rotate to drive the limit plate back to the initial state.

[0044] Furthermore, as a specific implementation, a guide plate 34 is provided between the two swing beams 2, and a sliding support member 30 is guided and cooperated on the guide plate. The rotating member includes two rotating shafts 31 respectively arranged on both sides of the sliding support member 30, and the ends of the rotating shafts 31 are rotatably cooperated with the sliding support member 30.

[0045] Specifically, refer to Figure 1-Figure 9 The guide plate 34 is extended along the length direction of the swing beam 2, the rotating member includes two rotating shafts 31, the guide plate 34 is preferably a dovetail plate, the sliding support member 30 includes a dovetail groove 303 that cooperates with the guide plate 34 for guiding, the rotating shaft 31 includes a second shaft end 311, and a second limiting protrusion 312 is arranged on the outer peripheral surface of the second shaft end close to one end of the rotating shaft 31, the sliding support member also includes a second matching hole 300 that is rotatably plugged with the second shaft end 311, the second matching hole is arranged through the sliding support member, and the length of the second shaft end 311 is less than or equal to the general length of the second matching through hole, both ends of the second matching through hole are coaxially provided with blind holes 301, and the side walls of the blind hole 301 are provided with a first limiting protrusion 302, refer to Fig. 9 When the second shaft end 311 extends into the second matching hole, the second limiting protrusion 312 can extend into the blind hole 301. Fig. 9 In the state shown, when the second limiting protrusion abuts against the first limiting protrusion, the rotating shaft 31 is in Figure 1 , Figure 2 The initial state shown, at this time the limit plate 33 is in the initial state, again refer to Fig. 9When the rotating shaft 31 rotates clockwise around the axis, and the other side of the second limiting protrusion 312 contacts the other side of the first limiting protrusion 302 for limiting, it can drive the limiting plate 33 to rotate to the working state, and at this time, the limiting plate 3 is parallel to the swing beam.

[0046] Further, as a specific implementation method, refer to Figure 5-Figure 8 , Fig.12 , Fig.13 A swing arm 32 is slidably sleeved and non-rotatably matched on the rotating shaft 31, a second sliding sleeve 331 is slidably sleeved on the swing arm 32, a driving device is arranged between the second sliding sleeve 331 and the swing arm, the driving device can drive the second sliding sleeve 331 to move along the swing arm 32, and a guide plate 34 is arranged on the second sliding sleeve 331.

[0047] Specifically, the swing arm 32 includes a first sliding sleeve 321, which is arranged on the rotating shaft 31 and non-rotatingly cooperates with the rotating shaft 31. The swing arm 32 is a strip structure with a rectangular cross-section. A second sliding sleeve 331 is provided on the swing arm for guiding sliding. A limiting end plate 332 is provided at the end. The limiting plate 33 is fixedly provided on the second sliding sleeve 331. A first strip groove 320 is provided on one surface of the swing arm, and a rack 3201 is provided on the bottom surface of the first strip groove. A driving motor 37 is also provided on the second sliding sleeve. The output shaft 371 of the driving motor is transmission-connected with a gear 372, and the transmission gear 372 is meshed with the rack 3201. By controlling the forward and reverse rotation of the driving motor 37, the second sliding sleeve 331 is driven to slide on the swing arm 32, thereby driving the limiting plate 33 to move.

[0048] Further, as a preferred embodiment, refer to Figure 6 , Fig.12 , Fig.13 A one-way limiting assembly 38 is provided between the second sliding sleeve 331 and the swing arm 32 .

[0049] Specifically, a second strip groove 322 is provided on one side of the swing arm 32 close to the limiting plate 33, a one-way ratchet 3220 is provided at the bottom of the second strip groove 322, a one-way limiting assembly 38 is provided on the second sliding sleeve 331, a guide channel 3310 which coincides with the second strip groove 322 is provided on the second sliding sleeve 331, the one-way limiting assembly 38 comprises a cylinder 381 which is coaxially arranged with the guide channel, a limiting step 3810 which is arranged in the middle area of ​​the cylinder and is arranged opposite to the second sliding sleeve 331, a first piston 380 which is arranged above the limiting step, and a guide arranged in the guide channel 3310. A guide column 385 and a rigid rod 383 connecting the guide column 385 and the first piston 380, a second compression spring 384 is arranged between the lower part of the first piston and the second sliding sleeve, a first connecting port 382 is arranged at the upper end of the cylinder, and a connecting hole 3811 is arranged at the lower end, a second blind hole 3851 is coaxially arranged at the guide column 385, and an end cover 388 is arranged at the end of the second blind hole, and the end cover and the rigid rod 383 are guided and slidably matched, a limiting nut 386 is arranged at the lower end of the rigid rod, and a third compression spring 387 is arranged between the limiting nut 386 and the bottom of the second blind hole, and the first connecting port 382 is connected to the gas source, refer to Fig.13 When the gas source does not supply compressed gas to the first connecting port, the first piston abuts against the upper end of the cylinder under the elastic force of the second compression spring 384. At this time, the rigid rod 383 pulls the guide column 385 to be in Fig.13 In the state shown, the lower end of the guide column 385 does not overlap with the one-way ratchet 3220 and does not play a one-way limiting role. When the limiting plate 33 is required to limit the wall, the air source supplies compressed gas into the cylinder. At this time, the first piston is pushed by the air pressure to squeeze the second compression spring 384 to move, thereby pushing the rigid rod 383 to move downward, pushing the guide column 385 to move downward, so that the lower end of the guide column abuts against the one-way ratchet 3220 and partially compresses the third compression spring 387. The guide column 385 is made of steel. The manufactured plate body has an inclined surface at the end that cooperates with the one-way ratchet. At this time, when the driving motor drives the second sliding sleeve 331 to slide in the direction of the rotating shaft, the guide column passes through the one-way ratchet 3220 in turn, and reciprocates the third compression spring 387 in this process to ensure that the second sliding sleeve can slide. After the limit plate 33 contacts the wall, the driving motor stops working. At this time, the air source continues to supply compressed gas to ensure that the guide column 385 cooperates with the one-way ratchet to unidirectionally cooperate with the second sliding sleeve, thereby ensuring that the limit plate 33 continues to limit the wall.

[0050] After the wall is assembled, the air source stops supplying air. At this time, the first piston is pushed back under the elastic force of the second compression spring 384, and the guide column is pulled upward through the rigid rod 383 to separate from the one-way ratchet. At this time, the driving motor rotates in the opposite direction to drive the second sliding sleeve back to the end of the swing arm 32. Specifically, a detection member 5 can be set on the limit plate 33 to detect whether the limit plate is in contact with the wall and the distance between the limit plate and the wall, so as to control the operation of the driving motor. The detection member can be a laser distance sensor.

[0051] Further, as a preferred embodiment, refer to Figure 3-Figure 7 , Fig.10 , Fig.11 , a friction wheel 36 is coaxially arranged on the rotating shaft 31, and a plate body 25 is arranged between the two swing beams 2 to frictionally cooperate with the outer peripheral surface of the friction wheel 36. Specifically, the rotating shaft 31 also includes a first shaft end 310, on which the friction wheel 36 is sleeved, and a first matching hole 260 is arranged on the second sliding member 26 to rotatably cooperate with the first shaft end 310. A rigid plate body 25 is arranged between the two swing beams 2, and the plate body 25 is located on the side of the first support member and the second support member close to the power telescopic rod 4. The guide plate 34 is fixedly arranged on the plate body 25, and the outer peripheral surface of the friction wheel is tangent to the extension surface of the upper surface of the plate body 25. Figure 1 , Figure 2 When the upper limit assembly 3 is in the initial state, the plate body 25 and the friction wheel do not overlap. When the upper limit assembly 3 needs to limit the wall, the driving shaft 31 moves downward. When the friction wheel 36 overlaps with the plate body 25, the plate surface of the plate body 25 rubs against the outer peripheral surface of the friction wheel 36. With the movement of the shaft 31, the shaft 31 is driven to rotate around the axis under the action of the friction force, thereby driving the swing arm 32 to swing until it rotates to the limit plate 33 and the swing beam are parallel. The second limit protrusion 312 and the first limit protrusion 302 limit the shaft, and the shaft no longer rotates, and the limit plate 33 is kept in a state parallel to the swing beam. Through this setting, the shaft 31 can be driven to rotate by the friction force of the friction wheel when it translates, without the need to set up an additional device to drive the shaft to rotate, thereby simplifying the structure.

[0052] Further, refer to Fig.10 , Fig.11The friction wheel 36 includes a support sleeve 361 sleeved on the outer circumference of the first shaft end 310, an outer layer 360 arranged outside the support sleeve 361, at least one groove 3101 is arranged on the outer circumference of the first shaft end 310, a guide through hole 362 is radially arranged on the support sleeve 361, the outer end of the guide through hole is threadedly connected with a second limiting plate 363, a limiting column 364 is arranged in the guide through hole, and a first compression spring 365 is arranged between the second limiting plate 363 and the limiting column 364. By this arrangement, the limiting column 362 is radially arranged. The end of 64 penetrates into the groove 3101, providing a circumferential limiting resistance to the support sleeve 361, and the friction wheel can drive the rotating shaft 31 to rotate through the friction resistance. After the second limiting protrusion 312 and the first limiting protrusion 302 are limited, the first compression spring 365 can be compressed when the friction wheel continues to rotate, so that the friction wheel and the first shaft end 310 can rotate relative to each other, thereby reducing the damage to the outer layer 360 caused by the sliding friction between the outer peripheral surface of the friction wheel and the plate body 25, thereby increasing the service life of the friction wheel, wherein the outer layer 360 is a rubber layer.

[0053] As a specific implementation, the driving shaft 31 can be driven to translate by any one of an electric push rod, a hydraulic push rod and a pneumatic push rod.

[0055] refer to Fig.14 , Fig.15 The state shown in the figure is a schematic diagram of the state when there is no wall placed on the bearing plate 27. At this time, the control valve 86 is in an open state, the connecting pipe 84 and the first connecting port 382 are connected to the atmosphere, and the state of the one-way limit assembly 38 is as shown in FIG. Fig.13 As shown, the first sliding member 22 and the second sliding member 26 are in the following position under the elastic force of the fourth compression spring 87 and the fifth compression spring 89. Fig.14 The state shown, at this time, the upper limit component 3 is in Figure 1 , Figure 2In the initial state shown, when assembling the wall, the control valve 86 is closed. After the wall is placed on the bearing plate 27, the crane controls the wall to fall, so that the bearing plate can be pushed to drive the first sliding member 22 to move downward, and the second piston 800 is pulled downward by the first pull rod 801, thereby squeezing the gas below the first columnar cavity 80 to increase the air pressure below, thereby supplying air pressure to the one-way limit assembly 38 and the second columnar cavity 81, and continuing to squeeze the gas during the falling process of the wall until the first sliding member 22 contacts the bottom of the internal space 28, and the high-pressure gas can push the third piston 810 to move, pull the second sliding member 26 to resist the elastic movement of the fourth compression spring 87, thereby pulling the rotating shaft 31 to move downward, and during the movement, the swing arm 32 is driven to swing until the swing arm abuts against the upper end of the wall. At this time, the wall is detected by the detection member 5, and the drive motor 37 works to drive the second sliding sleeve 331 to move until the limit plate 33 contacts the wall, and the drive stops, completing the upper end limit of the wall. Then adjust the power telescopic rod 4 to make the swing beam 2 swing to a vertical state, and then assemble the wall support. During the assembly process, the height of the wall can also be adjusted by telescoping the second power telescopic rod 9 to facilitate assembly. After the assembly is completed, open the control valve 86 to release the gas and release the air pressure. At this time, the one-way limit assembly 38 returns to its original position, and the second sliding member 26 returns to its original position under the elastic force of the fourth compression spring. The drive motor is controlled to rotate in the opposite direction to return the limit plate to its initial position, and then the bottom beam 1 is translated to separate from the wall.
