Description

Technical Field

[0001] This invention relates to the technical field of aluminum formwork systems, and more particularly to a support reduction device for aluminum formwork systems used in civil engineering construction. Background Technology

[0002] In the construction of aluminum formwork systems, traditional support devices typically use multiple independent support columns to provide support, which has many drawbacks. On the one hand, a large number of support columns need to be installed, resulting in a huge workload for workers and low installation efficiency. For example, in large-scale construction projects, a lot of manpower and time are often spent on the layout and installation of support columns to ensure the stability of the aluminum formwork. On the other hand, the use of numerous support columns not only increases material costs but also occupies a lot of construction site space, causing inconvenience to the organization and management of on-site construction, easily leading to congestion and chaos on the construction site, affecting the smooth progress of other construction stages, and thus slowing down the overall project progress.

[0003] In addition, in some construction scenarios, such as when the disassembled support rod is passed to the construction workers upstairs by lifting it, the traditional method often relies on the construction workers' arms to lift it upwards. This makes the workers' arms prone to injury and the work efficiency extremely low, which greatly increases the labor intensity of the construction workers and the construction safety risks. Summary of the Invention

[0013] As a preferred embodiment of the support reduction device for the aluminum formwork system in civil construction described in this invention, the first connecting plate has a through groove at its center, the diameter of which is slightly larger than the diameter of the second support rod; the first connecting plate is hinged to the end of the first movable rod, the end of the first movable rod is hinged to the end of the first movable plate, and the other end of the first movable plate is hinged to the second support rod.

[0018] By engaging the support cylinder with the second support rod, rotating the support cylinder causes the first thread on the inner wall of the second support rod to no longer contact the adjusting thread groove. At this point, under the action of the spring force at the end of the connecting rod, the total length of the first and second support rods reaches its maximum. This allows the worker below to pass the end of the support rod to the worker above without having to lift it up with their arms, thus greatly reducing the workload and arm injuries for construction workers and improving work efficiency.

Detailed Implementation

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0029] Example 1, referring to Figures 1 to 2 This invention provides a first embodiment of a support reduction device for an aluminum formwork system in civil engineering construction. The device includes a support mechanism 100, comprising a first support rod 101, a second support rod 102 mounted on the first support rod 101, and a multi-point support member 103 mounted on the second support rod 102. An adjustment mechanism 200 is mounted on the support mechanism 100, comprising a switching member 201 mounted on the second support rod 102 and a locking member 202 mounted on the adjustment member. The multi-point support member 103 is used to provide multiple support points 103d on the second support rod 102, providing multi-point support force. The adjustment mechanism 200 controls the position and locking state of the multi-point support member 103 on the second support rod 102, and also controls the total length of the first support rod 101 and the second support rod 102.

[0030] It should be noted that by setting multiple support points 103d on the second support rod 102, the traditional support method of a single support point 103d or a small number of support points 103d is changed, allowing the support force to be distributed more evenly on the aluminum formwork, greatly improving the stability of the support. Compared with single-point support, it can better resist external forces from different directions, such as wind force and collision forces during construction, effectively preventing deformation or displacement of the aluminum formwork during construction, ensuring construction accuracy and quality, and achieving the effect of reducing the number of support columns without reducing the number of support points 103d, greatly reducing the workload of workers installing support columns.

[0031] Specifically, a connecting base 101a is provided at the end of the first support rod 101 away from the second support rod 102, and a first adjusting member 101b is provided at the end of the first support rod 101 away from the connecting base 101a. The first adjusting member 101b cooperates with the adjusting mechanism 200 to control the total length of the first support rod 101 and the second support rod 102.

[0032] The first adjusting member 101b includes a connecting rod 101b-1 disposed at the end of the first support rod 101, a connecting spring 101b-2 disposed at the end of the connecting rod 101b-1, and a telescopic rod 101b-3 disposed at the end of the connecting rod 101b-1. The connecting rod 101b-1 is inserted into the second support rod 102. It should be noted that a rotating disk is provided at the end of the connecting rod 101b-1 connected to the connecting spring 101b-2. The rotating disk is always connected to the end of the connecting rod 101b-1 and rotates along the central axis of the connecting rod 101b-1, so that when the second support rod 102 drives the spring to rotate, the first support rod 101 can remain stationary. It should also be noted that the end of the telescopic rod 101b-3 is inserted into the end of the connecting rod 101b-1 and the end of the inner wall of the second connecting rod 101b-1, respectively.

[0033] Furthermore, the outer wall of the connecting rod 101b-1 is provided with an adjusting threaded groove 101b-4, which is located at the end of the connecting rod 101b-1 connected to the first support rod 101. One end of the connecting spring 101b-2 and the telescopic rod 101b-3 are both connected to the end of the connecting rod 101b-1, and the other end of the connecting spring 101b-2 and the telescopic rod 101b-3 are both connected to the inner wall of the second support rod 102. The inner wall of the second support rod 102 is provided with a first thread, which is adapted to the adjusting threaded groove 101b-4.

[0034] Example 2, refer to Figures 1 to 4This embodiment differs from the first embodiment in that: the outer wall of the second support rod 102 is provided with a second thread 102a and a third thread 102b, the second thread 102a being close to the first thread and the third thread 102b being away from the first thread; a first snap-fit ​​hole 102c is provided below the second thread 102a, and a second snap-fit ​​hole 102d is provided below the third thread 102b; the inner wall of the second support rod 102 is provided with an insertion groove, which is adapted to the connecting rod 101b-1. It is worth noting that during the adjustment of the total length of the first support rod 101 and the second support rod 102, the insertion groove provides a guiding function for the movement of the connecting rod 101b-1, so that the connecting rod 101b-1 can only move along the direction of the insertion groove, avoiding the displacement or misalignment of the connecting rod 101b-1 during rotation or other operations, and ensuring the smoothness and accuracy of the adjustment process. Meanwhile, the size and shape of the insertion slot limit the range of motion of the connecting rod 101b-1, preventing excessive elongation or detachment, thereby ensuring the structural integrity and safety of the support device in different length states.

[0035] It should be noted that a support point 103d is fixedly provided at the end of the second support rod 102. That is, this device has three support points 103d at the end of one support rod, which reduces the number of books to be installed on the support rod, but does not reduce the number of support points 103d, that is, does not reduce the supporting force, thereby reducing the workload of the staff in installing the support rod.

[0036] Specifically, the multi-point support member 103 includes a first connecting plate 103a, a first movable rod 103b disposed on the first connecting plate 103a, a first movable plate 103c disposed on the first movable rod 103b, and a support point 103d disposed on the first movable plate 103c; the first movable rod 103b, the first movable plate 103c, and the support point 103d are all mirror images of each other with the central axis of the second support rod 102 as the center.

[0037] Furthermore, a through groove is provided at the center of the first connecting plate 103a, and the diameter of the through groove is slightly larger than the diameter of the second support rod 102. The first connecting plate 103a is hinged to the end of the first movable rod 103b, the end of the first movable rod 103b is hinged to the end of the first movable plate 103c, and the other end of the first movable plate 103c is hinged to the second support rod 102. It is worth noting that a U-shaped groove is provided at the hinge point between the first movable rod 103b and the first movable plate 103c. The purpose of providing the U-shaped groove is to prevent jamming when the angle between the first movable rod 103b and the first movable plate 103c changes.

[0038] The rest of the structure is the same as in Example 1.

[0039] Example 3, referring to Figures 1 to 4This embodiment differs from the above embodiments in that: the switching component 201 includes a support cylinder 201a disposed on the outer wall of the second support rod 102 and a handle 201b disposed on the outer wall of the support cylinder 201a; the support cylinder 201a is sleeved on the outer wall of the second support rod 102, and a support thread groove is provided on the inner wall of the end of the support cylinder 201a near the multi-point support component 103, and the support thread groove is adapted to both the second thread 102a and the third thread 102b.

[0040] It should be noted that in this invention, the support cylinder 201a plays two key roles: The support cylinder 201a is sleeved on the outer wall of the second support rod 102, and its inner wall has a support thread groove that matches the second thread 102a and the third thread 102b on the outer wall of the second support rod 102, enabling the support cylinder 201a to move up and down and rotate on the second support rod 102. During installation, by moving the support cylinder 201a to different thread positions and rotating it, the second support rod 102 is rotated, thereby adjusting the position of the multi-point support member 103 (such as the end support point 103d of the first movable plate 103c), allowing it to accurately engage in the preset support position and effectively support the aluminum mold system.

[0041] The rotational fit between the support cylinder 201a and the second support rod 102 plays a crucial role in adjusting the overall length of the first support rod 101 and the second support rod 102. By rotating the support cylinder 201a, the first thread on the inner wall of the second support rod 102 moves along the adjusting thread groove 101b-4 of the connecting rod 101b-1 in the first adjusting member 101b, thereby changing the relative position of the first support rod 101 and the second support rod 102 and adjusting the overall length to meet the support requirements of different heights or facilitate handling after disassembly.

[0042] Specifically, the engaging component 202 includes a central rod 202a disposed on the support cylinder 201a and a pressing plate 202b disposed on the central rod 202a; a engaging block 202c is disposed at the end of the pressing plate 202b away from the handle 201b, and an engaging through hole 202d is also disposed on the support cylinder 201a, and the engaging block 202c is adapted to the engaging through hole 202d, the first engaging hole 102c and the second engaging hole 102d.

[0043] Furthermore, a torsion spring is provided on the outer wall of the center rod 202a, and the torsion spring is connected to the pressing plate 202b, which is hinged to the center rod 202a.

[0044] The rest of the structure is the same as in Example 2.

[0045] Operation process: The initial state of the present invention is set as follows: the angle between the first movable rod 103b and the first movable plate 103c is 0°, the total length of the first support rod 101 and the second support rod 102 is at its shortest, and the engaging part 202 on the support cylinder 201a is in a non-engaged state.

[0046] When using this invention during construction, first align the support point 103d at the end of the second support rod 102 with the position requiring support. Then, connect the base of the first support rod 101 to the ground with bolts. At this time, the first support rod 101 and the second support rod 102 are perpendicular to the ground. Then, move the support cylinder 201a downward so that the support thread groove on the inner wall of the support cylinder 201a is fully connected with the second thread 102a. When the support thread groove is fully connected with the second thread 102a, press down one end of the pressing plate 202b which is provided with the engaging block 202c, so that the engaging block 202c on the pressing plate 202b simultaneously engages with the engaging through hole 2. 02d and the first snap-fit ​​hole 102c, at this time the support cylinder 201a and the second support rod 102 are connected through the snap-fit ​​block 202c. At this time, rotate the handle 201b on the outer wall of the support cylinder 201a clockwise, and the second support rod 102 will rotate simultaneously under the rotation force of the support cylinder 201a, so that the first thread on the inner wall of the second support rod 102 moves upward along the adjusting thread groove 101b-4 until the support point 103d at the end of the second support rod 102 is inserted into the preset support position. At this time, press the end of the pressing plate 202b away from the snap-fit ​​block 202c, so that the support cylinder 201a is no longer connected to the second support rod 102 through the snap-fit ​​block 202c.

[0047] Next, the support cylinder 201a is moved upward along the outer wall of the second support rod 102 to the third thread 102b. Then, the handle 201b of the support cylinder 201a is rotated, moving the support thread groove of the support cylinder 201a from one end to the other along the third thread 102b. During the movement of the support thread groove along the third thread 102b, the included angle between the first movable rod 103b and the first movable plate 103c changes continuously until the support point 103d at the end of the first movable plate 103c is aligned with... The support point 103d at the end of the second support rod 102 is also engaged in the preset support position. At this time, the support cylinder 201a is no longer rotated. Since the end of the support cylinder 201a is in contact with the bottom end of the first connecting plate 103a, the support cylinder 201a cannot move upward. At this time, press down one end of the pressing plate 202b which is provided with the locking block 202c, so that the locking block 202c on the pressing plate 202b simultaneously engages with the locking through hole 202d and the second locking hole 102d. Thus, the entire support device is installed.

[0048] As can be seen from the above, the present invention achieves the effect of reducing the number of installation support columns by cooperating with the multi-point support member 103 and the support cylinder 201a, but without reducing the number of support points 103d, which greatly reduces the workload of the workers in installing the support columns, while not reducing the corresponding support force.

[0049] However, in construction scenarios such as civil engineering, there is a need to transport the disassembled support rods to the upper construction site. The usual solution is for construction workers to lift the support rods upwards by arm, and then workers on the upper floor take the ends of the support rods and lift them up. During this process, workers at lower levels need to repeatedly lift the support rods upwards by arm, which can easily lead to arm injuries and is inefficient. In this invention, the support cylinder 201a, in conjunction with the second support rod 102 and the first support rod 101, can reduce this problem. Specifically, the operation method is as follows: first, the disassembled support rods are transported to the upper construction site. After removing the rod, first press the end of the pressing plate 202b away from the engaging block 202c, so that the engaging block 202c is no longer engaged with the engaging through hole 202d and the second engaging hole 102d. Then move the support cylinder 201a downwards. At this time, the first movable rod 103b and the first movable plate 103c gradually return to their initial state. Then continue to move the support cylinder 201a downwards until the support thread groove on the inner wall of the support cylinder 201a is completely connected with the second thread 102a. When the support thread groove is completely connected with the second thread 102a, press the end of the pressing plate 202b where the engaging block 202c is located, so that... The engaging block 202c on the pressing plate 202b simultaneously engages with the engaging through hole 202d and the first engaging hole 102c. At this time, the support cylinder 201a and the second support rod 102 are connected through the engaging block 202c. Rotating the handle 201b on the outer wall of the support cylinder 201a counterclockwise causes the second support rod 102 to rotate simultaneously under the rotational force of the support cylinder 201a. This causes the first thread on the inner wall of the second support rod 102 to move downwards along the adjusting thread groove 101b-4 until the support point 103d at the end of the second support rod 102 no longer contacts the preset support position. At this point, the first support rod 101 is pushed to the position where upward transmission is required. At the designated point, the support cylinder 201a is rotated counterclockwise. As the support cylinder 201a rotates counterclockwise, the second support rod 102 rotates upward along the outer wall of the connecting rod 101b-1 until the first thread on the inner wall of the second support rod 102, driven by the support cylinder 201a, no longer contacts the adjusting thread groove 101b-4 on the outer wall of the connecting rod 101b-1. At this point, the spring bounces upward, the telescopic rod 101b-3 reaches its maximum length, and the total length of the first support rod 101 and the second support rod 102 also reaches its maximum. At this point, the worker above can touch the end of the second support rod 102 and thus move the entire device upward.

[0050] That is, by engaging the support cylinder 201a with the second support rod 102, rotating the support cylinder 201a causes the first thread on the inner wall of the second support rod 102 to no longer contact the adjusting thread groove 101b-4. At this time, under the action of the spring force at the end of the connecting rod 101b-1, the total length of the first support rod 101 and the second support rod 102 reaches its maximum. This allows the worker below to pass the end of the support rod to the worker above without having to lift the support rod with their arms, so that they can proceed to the next step of the work. This greatly reduces the workload and arm injury for construction workers and improves work efficiency. Moreover, this invention solves the above-mentioned technical problems by moving the support cylinder 201a up and down along the outer wall of the second support rod 102. The structure is simple, the operation is convenient, and it is suitable for widespread promotion.
