[0056] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0057] First embodiment:

[0058] like Figure 1 As shown, a stable structure of aluminum formwork for building construction provided by the first embodiment of the utility model includes a base 1, a plurality of slide bars 2, a support part 3, a clamping part 4 and a driving part 5. The base 1 is used to be placed on the ground to provide a supporting foundation; the plurality of slide bars 2 are movably mounted on the base 1 along the vertical direction, and the support part 3 is fixed on the top of the plurality of slide bars 2 to support the aluminum formwork; the clamping part 4 is mounted on the support part 3 to clamp the aluminum formwork; the driving part 5 is in transmission connection with the support part 3, so that the support part 3 is driven to move up and down through the driving part 5 to adjust the supporting height of the aluminum formwork.

[0059] Specifically, Figure 2 As shown, in this embodiment, the base 1 is roughly trapezoidal in shape, with an avoidance groove 11 at the bottom and a plurality of mounting holes 12 at the top in the vertical direction. The avoidance groove 11 is used to provide an installation space for the drive unit 5, and there are four mounting holes 12, which are respectively located at the four corners of the top of the base 1, so that four slide bars 2 can be installed and the four slide bars 2 are respectively located at the four corners of the top of the base 1. It can be understood that in other embodiments, the number and position of the mounting holes 12 can also be adjusted as needed. For example, three mounting holes are respectively provided on both sides of the top of the base 1, so as to form six mounting holes for installing six slide bars 2. In addition, in this embodiment, preferably, as Figure 3 As shown, at least one stabilizing plate 13 is provided at both ends of the bottom of the base 1. The stabilizing plate 13 can rotate along the connection, so that the stabilizing plate and the base are set at an angle of 90 degrees, thereby increasing the force-bearing area and providing a certain stabilizing effect.

[0060] In this embodiment, preferably, the slide bar 2 is a cylindrical rod, so that the smoothness of the up and down movement can be improved by cooperating with the circular mounting hole 12. However, in other embodiments, the structural shape of the slide bar 2 can also be adaptively adjusted as needed, for example: the slide bar 2 is replaced with a square column, and accordingly, the mounting hole 12 is also set as a square hole. In addition, in another embodiment, preferably, an anti-slip sleeve (not shown in the figure) is sleeved on the outer side of each of the slide bars 2 to play the role of axial limit and anti-slip.

[0061] like Figure 2 As shown, the support portion 3 is fixed to the top of the plurality of slide bars 2 to support the aluminum formwork. Specifically, in the present embodiment, the support portion 3 is a rectangular plate, but is not limited to the specific structural form of the support portion 3. The bottom of the support portion 3 can be fixedly connected to the top of the four slide bars 2 by welding, bonding, threaded connection, etc., so that the support portion 3 can reciprocate along the vertical direction with the slide bars 2. In addition, the bottom of the support portion 3 is also connected to the driving portion 5 (described in detail below), so that the driving portion 5 provides a driving force for the support portion 3 to reciprocate along the vertical direction to adjust the support height of the support portion 3.

[0062] like Figure 1 As shown, the clamping portion 4 is movably disposed on the top of the supporting portion 3 to clamp the aluminum template. Figure 4 As shown, the clamping part 4 includes two clamping plates 41, two adjustment blocks 42, and positive and negative threaded rods 43. Among them, the two clamping plates 41 are parallel to each other and are arranged at the top of the support part 3. The two adjustment blocks 42 are respectively fixed to the bottom of the two clamping plates 41, and the top of the support part 3 is provided with a slideway 31 in the horizontal direction (the horizontal direction is perpendicular to the clamping plates 41), and the two adjustment blocks 42 are respectively movably installed in the slideway 31. The positive and negative threaded rod 43 has a positive thread section 431 and a negative thread section 432, and the positive thread section 431 and the negative thread section 432 are respectively threadedly connected with the two adjustment blocks 42. Therefore, when the positive and negative threaded rod 43 is rotated, the two adjustment blocks 42 can be driven to move in opposite directions along the slideway 31, thereby driving the two clamping plates 41 to move in opposite directions to adjust the distance between the two clamping plates 41, which is more convenient for clamping and fixing the aluminum template and improving the fixing and clamping effect of the aluminum template.

[0063] In addition, in this embodiment, preferably, a dovetail slider 44 is also provided at the bottom of the clamping plate 41, and correspondingly, a dovetail slot 32 is also provided at the top of the support portion 3 in the horizontal direction, and the dovetail slider 44 is slidably matched with the dovetail slot 32 to limit the relative position of the clamping plate 41 and the support portion 3, and to prevent the clamping plate 41 from being separated from the support portion 3, thereby ensuring the safety and stability of use. More preferably, anti-skid protrusions 45 are provided on the two opposite inner sides of the two clamping plates 41, and the anti-skid protrusions 45 can be used to increase the friction coefficient between the clamping plate 41 and the aluminum template, thereby improving the stability of clamping the aluminum template.

[0064] like Figure 1 As shown, in this embodiment, the driving part 5 is located in the avoidance groove 11, and the power output end of the driving part 5 passes through the top surface of the base 1 and is connected to the bottom surface of the support part 3. Therefore, the driving part 5 can drive the multiple slide bars 2 to move back and forth in the vertical direction to adjust the support height of the support part 3. Specifically, as Figure 2 As shown, the driving part 5 includes an adjusting nut 51, an adjusting threaded rod 52 and a turntable 53. The adjusting nut 51 is fixed to the top of the base 1, and a through hole 14 is provided on the top of the base 1 at a position corresponding to the adjusting nut 51. The adjusting threaded rod 52 passes through the through hole 14 and is threadedly connected to the adjusting nut 51, and the top of the adjusting threaded rod 52 (i.e., the power output end of the driving part 5) is rotatably connected to the bottom of the support part 3, so that the adjusting threaded rod 52 and the support part 3 can rotate relative to each other but cannot move relative to each other. The turntable 53 is installed at the bottom of the adjusting threaded rod 52 to drive the adjusting threaded rod 52 to rotate.

[0065] The working principle of the stable structure of the aluminum formwork for house construction is described in detail below:

[0066] By rotating the turntable 53, the turntable 53 will drive the adjusting threaded rod 52 to rotate, and the adjusting threaded rod 52 is threadedly matched with the adjusting nut 51 to convert the rotational motion of the adjusting threaded rod 52 into a linear motion along the vertical direction. Since the adjusting threaded rod 52 is rotatably connected to the bottom of the support part 3 (relatively rotatable but not relatively movable), the adjusting threaded rod 52 can transmit the vertical force to the support part 3, so that the support part 3 moves with the movement of the slide bar 2 in the mounting hole 12, thereby achieving the raising or lowering of the support part 3, and then achieving the effect of supporting aluminum templates of different heights.

[0067] It can be understood that in the present embodiment, the driving part 5 provides driving force manually. In other embodiments, the driving part 5 can also adopt a driving motor or a cylinder, and can be provided with a controller (for example: a PLC controller or a single-chip microcomputer, etc.) electrically connected to the driving part 5, so as to realize automatic adjustment of the height of the support part 3.

[0068] In summary, the embodiment of the utility model provides a stabilizing structure for aluminum formwork for building construction, which achieves the effect of supporting aluminum formworks of different heights by adjusting the height of the support part 3, thereby solving the problem that most aluminum formwork stabilizing devices for building construction are difficult to stabilize aluminum formworks of different heights.

[0069] Second embodiment:

[0070] like Figure 5 As shown, a second embodiment of the utility model provides a stable structure of aluminum formwork for building construction, including a base 1, a plurality of slide bars 2, a support portion 3, a clamping portion 4 and a driving portion 5. Compared with the first embodiment, the difference of this embodiment is that it also includes a fixing portion 6.

[0071] Specifically, in this embodiment, the fixing portion 6 is a rectangular plate, and the four corners of the rectangular plate are respectively fixed on a slide bar 2 to limit and fix the four slide bars 2, so that the four slide bars can be driven to move upward through the fixing portion 6 to achieve the effect of lifting, and the sliding movement of the slide bars inside the base is not affected. Correspondingly, the support portion 3 is fixed to the top of the plurality of slide bars 2 and is located above the fixing portion 6 to support the aluminum template. In addition, the power output end of the driving portion 5 passes through the top surface of the base 1 and is connected to the bottom surface of the fixing portion 6.

[0072] During specific use, the driving force can be transmitted to the fixing part 6 through the driving part 5, thereby driving the four sliding rods 2 to rise or fall vertically through the fixing part 6, and then driving the supporting part 4 to rise or fall vertically through the sliding rod 2, thereby achieving the purpose of adjusting the supporting height of the aluminum formwork.

[0073] Except for the above differences, the remaining features of this embodiment are the same as those of the first embodiment and will not be described herein again.

[0074] Third embodiment:

[0075] like Figure 6 and Figure 7 As shown, a stable structure of aluminum formwork for building construction provided by the third embodiment of the utility model comprises a base 1, a plurality of slide bars 2, a support part 3, a clamping part 4 and a driving part 5. Compared with the first embodiment, the difference of this embodiment is that the base 1 can be raised and lowered.

[0076] Specifically, a lifting roller 7 is installed at the bottom of the base 1, and the lifting roller 7 can be switched between an extended state and a retracted state. Figure 6 As shown, in the extended state, the lifting roller 7 protrudes out of the bottom of the base 1 and contacts the ground. At this time, the entire building aluminum formwork stable structure can be easily pushed to move on the ground to freely adjust the position of the building aluminum formwork stable structure. Figure 7As shown, in the retracted state, the lifting roller 7 is hidden in the base 1 so that the bottom of the base 1 is in contact with the ground.

[0077] It can be seen from this that when the aluminum formwork stabilizing structure for building construction needs to be used, the lifting roller 7 can be retracted to ensure the stability of the support of the aluminum formwork stabilizing structure for building construction; when the aluminum formwork stabilizing structure for building construction is used up, the lifting roller 7 can be extended to move the aluminum formwork stabilizing structure for building construction to a suitable parking area for the next use.

In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples, unless they are contradictory.

[0079] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
