Description

Technical Field

[0001] This invention relates to the field of building construction support frame technology, and specifically to an adjustable support frame for building construction. Background Technology

[0002] Steel pipe scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It is divided into external scaffolding and internal scaffolding according to its location. To increase the stability and strength of the scaffolding, steel pipes are usually used for its construction. At the same time, to improve stability during installation, steel pipe scaffolding needs to be positioned with the help of support frames.

[0003] Currently, in existing technologies, after the vertical steel pipes are positioned, horizontal steel pipes need to be installed between the two sets of vertical steel pipes. In practical applications, when the distance between the two sets of vertical steel pipes is too large, the horizontal steel pipes need to be connected and lengthened so that the length of the lengthened horizontal steel pipes matches the distance between the vertical steel pipes. However, after the connection is completed, workers still need to connect it to the vertical steel pipes. When the installation height is high, it is difficult to operate manually. At the same time, existing technologies can only install one set of horizontal steel pipes at a time, resulting in low installation efficiency. Summary of the Invention

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please see Figure 1 As shown, the present invention is an adjustable support frame for building construction, including two sets of symmetrically arranged workbenches 3. Each set of workbenches 3 is symmetrically arranged with two sets of positioning modules for positioning horizontal steel pipes 203. In one embodiment of this invention, when docking the two sets of horizontal steel pipes 203, the horizontal steel pipes 203 are first positioned on both sides of the workbench 3 by the positioning modules. Since there are two sets of workbenches 3, each operation can dock two pairs of horizontal steel pipes 203, thereby improving docking efficiency.

[0039] The workbench 3 is also equipped with an adjustment module, which is used to drive the positioning modules on both sides to move closer or further away synchronously, so as to insert the positioned horizontal steel pipe 203 into the positioning tube 202; specifically, after the two sets of horizontal steel pipes 203 are positioned by the positioning module, the positioning tube 202 is placed between the two sets of horizontal steel pipes 203, and then the adjustment module drives the positioning modules on both sides to move closer synchronously, thereby driving the horizontal steel pipe 203 to move and be inserted into the positioning tube 202;

[0040] It also includes a lifting module, which drives the worktable 3 to move vertically to achieve height adjustment; it can be noted that, please refer to Figure 3 After the two sets of horizontal steel pipes 203 are inserted and positioned with the positioning pipes 202, the lifting module drives the worktable 3 to rise, so that the extended horizontal steel pipes 203 move to the installation position. The tee pipe 201 is sleeved on the vertical steel pipe 2 and slid to the installation position. Then, the adjustment module drives the two horizontal steel pipes 203 to move a specified distance away from each other, so that one end of the horizontal steel pipe 203 is inserted into the positioning pipe 202, and the other end is inserted into the tee pipe 201, thereby realizing the connection between the extended horizontal steel pipe 203 and the vertical steel pipe 2. After the connection is completed, the lifting module drives the worktable 3 to reset. In this embodiment, it is not necessary to manually hold the horizontal steel pipes 203 for docking, and two pairs of horizontal steel pipes 203 can be docked and installed at one time, which is more efficient.

[0041] Example 2

[0042] Based on Example 1, please refer to Figure 4 Each positioning module includes two sets of V-shaped plates 5. The two side walls of the V-shaped plates 5 are symmetrically provided with positioning grooves 501. The positioning grooves 501 are slidably embedded with clamping blocks 502. The upper side of the two sets of clamping blocks 502 that are close to each other is provided with an inclined surface 503, and the lower side is provided with an arc-shaped surface 504 for abutting against the outer wall of the horizontal steel pipe 203.

[0043] It also includes elastic mechanisms arranged on both sides of the V-shaped plate 5, which are connected to the clamping blocks 502. It can be explained that when positioning the horizontal steel pipe 203, the horizontal steel pipe 203 is placed between the V-shaped plates 5, and the outer wall of the horizontal steel pipe 203 abuts against the inclined surface 503 of the clamping block 502. Then, the horizontal steel pipe 203 is pressed towards the bottom of the V-shaped plate 5, and the clamping blocks 502 on both sides can move in opposite directions. At this time, the elastic mechanism generates elastic force. When the horizontal steel pipe 203 moves to the bottom of the clamping block 502, the elastic mechanism can drive the clamping block 502 to reset, so that the arc surface 504 of the clamping block 502 abuts against the outer wall of the horizontal steel pipe 203, and thus the horizontal steel pipe 203 can be positioned under the action of elastic force.

[0044] In addition, this embodiment uses two sets of V-shaped plates 5 on a set of positioning modules to support the horizontal steel pipe 203, which makes the positioning stability of the horizontal steel pipe 203 higher and avoids the phenomenon of the horizontal steel pipe 203 tilting.

[0045] In this embodiment, the elastic mechanism includes two sets of limiting rods 506 symmetrically arranged on the outside of the V-shaped plate 5. A limiting plate 509 fixed to the clamping block 502 is slidably sleeved on the limiting rod 506. A limiting protrusion 507 is provided at the end of the limiting rod 506, and a return spring 508 is also provided on the limiting rod 506. Specifically, one end of the return spring 508 is fixed to the limiting plate 509, and the other end is fixed to the limiting protrusion 507. It can be explained that when the horizontal steel pipe 203 pushes the clamping blocks 502 on both sides to move, the clamping block 502 can drive the return spring 508 to deform and generate elastic force through the limiting plate 509, so as to drive the subsequent clamping block 502 to return to its original position.

[0046] As a further embodiment, a spacing adjustment mechanism is also provided on the two worktables 3. The spacing adjustment mechanism is used to adjust the spacing of the two V-shaped plates 5 to match the spacing of the vertical steel pipes 2. Specifically, in order to make the position of the extended horizontal steel pipes 203 connected on the two worktables 3 correspond to the position of the vertical steel pipes 2, in this embodiment, when positioning the horizontal steel pipes 203, the spacing can be adjusted by driving the two V-shaped plates 5 to move through the spacing adjustment module to match the position of the vertical steel pipes 2 with different spacings, thus having a wider range of applications.

[0047] Please see Figure 4 The spacing adjustment mechanism includes a cylinder 4 and a telescopic rod 401 respectively arranged on the workbench 3. The telescopic rod 401 is slidably inserted into the cylinder 4. Two sets of positioning rings 407 are symmetrically fixed on the cylinder 4 and the telescopic rod 401. A swing rod 404 is fixedly arranged on each positioning ring 407. A pin 410 is fixedly arranged at the end of the swing rod 404 away from the positioning ring 407. A positioning seat 409 is rotatably arranged on the pin 410. A V-shaped plate 5 is fixed on the positioning seat 409.

[0048] It also includes gears 405 fixedly arranged on the cylinder 4 and the telescopic rod 401 respectively. The gears 405 are connected to the rotating part that drives them to rotate. It can be explained that when adjusting the distance between the two V-shaped plates 5, the rotating part synchronously drives the gears 405 on the cylinder 4 and the telescopic rod 401 to rotate. The gears 405 synchronously drive the cylinder 4 and the telescopic rod 401 to rotate. The cylinder 4 and the telescopic rod 401 can drive the swing rod 404 to rotate through the positioning ring 407, thereby realizing the adjustment of the position of the V-shaped plate 5.

[0049] Please see Figure 2 and Figure 5The rotating part includes a U-shaped frame 6 symmetrically arranged between two sets of workbenches 3. The U-shaped frame 6 has racks 601 on both sides for meshing with gears 405. The bottoms of the two workbenches 3 are fixed by connecting frames 302, and a connecting plate 301 is fixedly arranged between the two connecting frames 302. A first screw 303 is spirally arranged in the connecting plate 301. The two U-shaped frames 6 are fixed by support plates 304, and the end of the first screw 303 is rotatably connected to the support plate 304. It can be explained that when driving the gears 405 on both sides to rotate synchronously, by rotating the first screw 303, the first screw 303 drives the U-shaped frame 6 to move vertically through the support plate 304, which in turn drives the gears 405 to rotate through the racks 601, achieving a synchronous effect.

[0050] It should also be noted that, in order to ensure the synchronization of the rotation of the cylinder 4 and the telescopic rod 401, please refer to [the relevant documentation / reference needed]. Figure 6 The inner wall of the cylinder 4 is provided with several sets of strip-shaped slots 403 arranged in a circumferential array. The telescopic rod 401 is provided with corresponding strip-shaped seats 402 that slide and engage with the strip-shaped slots 403 one by one. Specifically, when the cylinder 4 and the telescopic rod 401 are driven to rotate, the strip-shaped seats 402 engage with the strip-shaped slots 403 to keep the cylinder 4 and the telescopic rod 401 synchronized. Thus, when the horizontal steel pipe 203 is connected, the horizontal steel pipes 203 on both sides are always on the same axis.

[0051] In addition, a guide rod 505 is provided between the V-shaped plates 5 at the same horizontal position on both sides of the worktable 3. One end of the guide rod 505 is slidably connected to the positioning seat 409 at the bottom of one side of the V-shaped plate 5, and the other end is slidably connected to the positioning seat 409 at the bottom of the other side of the V-shaped plate 5. Specifically, the two ends of the guide rod 505 are also provided with retaining seats to prevent the guide rod 505 from falling off. Specifically, when the swing rod 404 rotates, the positioning seat 409 can be guided and limited by the guide rod 505, so that the open end of the V-shaped plate 5 always faces upward and avoids the phenomenon of tilting.

[0052] Please see Figure 5The adjustment module includes a second screw 408 rotatably arranged between two sets of workbenches 3. The threads on both sides of the second screw 408 have opposite directions. Nuts 411 are symmetrically spirally sleeved on the second screw 408. Drive plates 603 are symmetrically fixed on both sides of the nuts 411. The end of the drive plate 603 is fixed to a drive ring 406 rotatably arranged on the cylinder 4 and the telescopic rod 401. It can be explained that after the horizontal steel pipe 203 is positioned, when the horizontal steel pipe 203 is driven to be inserted into the positioning pipe 202 or the three-way pipe 201, the second screw 408 is rotated. During the movement of the nut 411 on the second screw 408, the drive plate 603 drives the cylinder 4 and the telescopic rod 401 to move, so that the telescopic rod 401 extends and retracts in the cylinder 4. This synchronously drives the telescopic rod 401 and the positioning ring 407 on the cylinder 4 to move, thereby driving the horizontal steel pipe 203 to be inserted into the positioning pipe 202 or the three-way pipe 201.

[0053] In addition, in this embodiment, a slide groove 305 is provided on the workbench 3, and a slide seat is slidably provided in the slide groove 305. Guide rings 306 are rotatably arranged on the cylinder 4 and the telescopic rod 401, and the bottom of the guide rings 306 is fixed to the slide seat through a guide plate. Specifically, when the telescopic rod 401 and the cylinder 4 are driven to move in the horizontal direction, the slide groove 305 and the slide seat are used for guidance and limitation, so that their horizontal movement stability is higher.

[0054] Furthermore, in order to ensure that the rack 601 and the gear 405 are always meshed when adjusting the position of the cylinder 4 and the telescopic rod 401, in this embodiment, a U-shaped limiting plate 602 is fixedly arranged on the end of each set of drive plates 603 facing the gear 405, and the U-shaped frame 6 is slidably connected to the U-shaped limiting plate 602; specifically, when the nut 411 moves, the drive plate 603 and the U-shaped limiting plate 602 can synchronously drive the U-shaped frame 6 to move, so that the U-shaped frame 6 and the gear 405 are always meshed.

[0055] Please see Figure 2 The lifting module includes a base 1, on which third screws 103 are symmetrically arranged. The other end of the third screws 103 is spirally connected to a support cylinder 102, and the other end of the support cylinder 102 is fixed to a connecting frame 302. A drive motor 104 is installed at the bottom of the base 1. The drive motor 104 is connected to the third screws 103 on both sides through two sets of belt pulley transmission mechanisms 101. Specifically, when adjusting the height of the worktable 3, the drive motor 104 is started. The drive motor 104 drives the third screws 103 on both sides to rotate through the belt pulley transmission mechanisms 101. While the third screws 103 extend and retract in the support cylinder 102, they can simultaneously drive the worktable 3 to rise and fall, so as to achieve height adjustment.

[0056] An adjustable support frame for building construction, the working method of which includes the following steps:

[0057] The horizontal steel pipe 203 is placed between the V-shaped plates 5, and the outer wall of the horizontal steel pipe 203 abuts against the inclined surface 503 of the clamping block 502.

[0058] Press the horizontal steel pipe 203 towards the bottom of the V-shaped plate 5. Under pressure, the clamping blocks 502 on both sides move in opposite directions. The elastic mechanism generates elastic force. When the horizontal steel pipe 203 moves to the bottom of the clamping block 502, the elastic mechanism drives the clamping block 502 to reset. The arc-shaped surface 504 of the clamping block 502 abuts against the outer wall of the horizontal steel pipe 203. Under the action of elastic force, the horizontal steel pipe 203 is positioned.

[0059] The positioning tube 202 is placed between two sets of horizontal steel pipes 203, and then the second screw 408 is rotated. During the movement of the nut 411 on the second screw 408, the cylinder 4 and the telescopic rod 401 are driven to move through the drive plate 603, and the telescopic rod 401 and the positioning ring 407 on the cylinder 4 are moved in sync, thereby driving the horizontal steel pipe 203 to move and be inserted into the positioning tube 202.

[0060] Start the drive motor 104. The drive motor 104 drives the third screws 103 on both sides to rotate through the belt pulley transmission mechanism 101. While the third screws 103 extend and retract in the support cylinder 102, they can simultaneously drive the worktable 3 to rise, so that the extended horizontal steel pipe 203 can move to the installation position.

[0061] A three-way pipe 201 is fitted onto the vertical steel pipe 2 and slid to the installation position. Then, the second screw 408 is rotated in the opposite direction to drive the horizontal steel pipes 203 on both sides to move a specified distance away from each other, so that one end of the horizontal steel pipe 203 is inserted into the positioning pipe 202 while the other end is inserted into the three-way pipe 201.

[0062] After the connection is complete, start the drive motor 104 to rotate in reverse, and the drive table 3 will be reset.
