Description

Technical Field

[0001] The utility model relates to the technical field of independent supports, in particular to an independent support for a construction joint and a post-casting strip. Background Art

[0002] In civil engineering and building construction, the treatment of construction joints and post-cast strips is a key link in ensuring the stability and durability of building structures. Construction joints refer to interruptions formed during the concrete pouring process due to process requirements or progress limitations, while post-cast strips are gaps reserved during structural construction to control the settlement or deformation of the building. These areas need to be poured or treated a second time after construction is completed to ensure the integrity and strength of the overall structure. However, due to the complex construction environment, the support work of construction joints and post-cast strips requires precise height adjustment and stability control to ensure the accuracy of concrete pouring during construction and the quality of subsequent construction.

[0003] Traditional construction joint and post-cast strip support devices mostly use a threaded support rod structure. The support height is adjusted by rotating the threaded tube on the upper part of the support rod. Although this design can achieve height adjustment, it has some limitations. First, the operator needs to climb to a higher position to make adjustments, which increases the difficulty of operation and safety risks during construction. Second, the contact area of ​​the traditional telescopic structure is limited. After the support rod is extended, it is easy to bend or become unstable. Especially when carrying heavier objects, this may cause the support rod to lose its supporting capacity and affect construction safety.

[0004] Therefore, it is very necessary to invent a kind of independent support of construction joint and post-casting belt. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0021] As attached Figure 1 To the attached Figure 3 shown.

[0022] The utility model provides an independent support for construction joints and post-cast strips, comprising a support base 1, a threaded support structure 2, a heavy sleeve 3, a positioning clamp 4 and a support rod 5, wherein: the support base 1 is fixedly installed on the ground, and the threaded support structure 2 is fixedly installed on the surface of the support base 1, and the heavy sleeve 3 is slidably installed on the threaded support structure 2; the positioning clamp 4 is engaged with the threaded support structure 2 by bolts and is located below the heavy sleeve 3; the support rod 5 is fixedly installed above the heavy sleeve 3.

[0023] The threaded support structure 2 includes a support base 21, a reinforcing rib 22, a threaded rod 23 and a stabilizing slide 24, and the support base 21 is fixedly mounted on the surface of the support base 1, and the reinforcing rib 22 is fixedly mounted between the support base 1 and the support base 21; the threaded rod 23 is fixedly mounted on the top of the support base 21, and the stabilizing slide 24 is opened inside the threaded rod 23.

[0024] The support rod 5 includes a support cylinder 51, a support head 52, a sliding rod 53, a support frame 54 and a support U-support 55, and a heavy sleeve 3 is fixedly installed on the bottom end of the support cylinder 51, and the support cylinder 51 is located on the outside of the threaded support structure 2; the support head 52 is fixedly installed on the top of the support cylinder 51, and the sliding rod 53 is fixedly installed inside the support head 52, and the sliding rod 53 is slidably installed inside the stabilizing slide 24 inside the threaded support structure 2; the support frame 54 is fixedly installed on the outside of the support head 52, and the support U-support 55 is fixedly installed on the top of the support frame 54.

[0025] The threaded support structure 2 is located below the support rod 5, and the threads on the outside of the threaded support structure 2 are engaged with the threads inside the positioning clamp 4. The threads on the outside of the threaded support structure 2 can move the heavy sleeve 3 in the vertical direction through the rotation of the positioning clamp 4; the support base 21 adopts a circular metal table, and the threaded rod 23 adopts a metal threaded tube, which is provided with a stabilizing slide 24 inside and coated with lubricating oil.

[0026] The support rod 5 as a whole can move along with the movement of the heavy sleeve 3, and the support cylinder 51 adopts a steel metal tube, and the sliding rod 53 adopts a metal rod; the sliding rod 53 can extend and retract inside the stabilizing slide 24 when following the vertical movement of the support rod 5 as a whole; the support U bracket 55 is supported on the support head 52 at the top of the support cylinder 51 through the support frame 54.

[0027] Three groups of auxiliary support legs 6 are provided on the outside of the support rod 5, and the auxiliary support legs 6 include two parts: a support and a leg. The support of the auxiliary support leg 6 is fixedly installed on the outside of the support rod 5; the auxiliary support leg 6 is tilted to one side; the leg inside the auxiliary support leg 6 is slidably installed inside the support and is tightened and fixed by driving bolts.

[0028] Compared with the existing technology, this case has the following significant advantages:

[0029] 1. Improved operational convenience:

[0030] The threaded adjustment part of the traditional support system is usually located at the upper part of the support rod. The operator needs to climb up to adjust the height, which increases the construction difficulty and safety hazards. In this case, the threaded support structure 2 is designed to have the threaded adjustment part at the lower part. The operator can adjust the height by rotating the positioning clamp 4 on the ground, which greatly simplifies the operation process and improves safety and construction efficiency.

[0031] 2. Enhanced stability of support rod 5:

[0032] Traditional telescopic support rods are prone to bending or tilting after extension, especially when carrying heavy objects. To overcome this problem, the present invention utilizes a stabilizing slide 24 in conjunction with a sliding rod 53, providing the support rod 5 with better guidance and stability during extension and retraction. This structure effectively prevents the support rod from shaking or bending during use, enhancing its overall support capacity.

[0033] 3. Adjustable height is more flexible:

[0034] In this case, the threaded rod 23 and the positioning clamp 4 in the threaded support structure are engaged with each other, thereby achieving precise height adjustment of the support rod 5 and a wide adjustment range. Compared with traditional technologies, this case allows more flexible height settings and is easy to operate without the need for multiple disassembly and assembly of parts.

[0035] 4. Enhanced carrying capacity:

[0036] This device ensures the overall structural strength when carrying heavy objects through the optimized design of the heavy sleeve 3 and the support frame 54. In particular, the design of the auxiliary support legs 6 further increases the overall support stability and carrying capacity. The three sets of auxiliary support legs 6 not only disperse the load pressure, but also provide additional supporting force to ensure that the support rod remains stable when carrying a large weight and will not tilt or collapse.

[0037] 5. Structural durability and smooth operation:

[0038] The threaded support structure of this case is specially made of metal material, and lubricating oil is added to the stabilizing slide 24 to ensure smooth operating performance even after long-term use. Compared with traditional equipment, it reduces equipment wear, extends service life, and improves maintenance convenience.

[0039] 6. Multiple stable design:

[0040] In addition to stabilizing the cooperation between the slide cylinder 24 and the sliding rod 53, this case further improves the overall stability of the device by setting the reinforcing ribs 22. The reinforcing ribs 22 are connected between the support base 1 and the support base 21, providing additional support force and torsional resistance for the support structure, ensuring safety and stability under high-intensity working conditions.

[0041] 7. Improved security:

[0042] Since the operator can adjust the support height directly on the ground, the frequent high-altitude operations in traditional technologies are avoided and the risk of falling during construction is reduced. In addition, the locking function of the positioning clamp 4 ensures the stability of the support rod after the adjustment is completed, and it will not loosen or slide due to accidental operation.

[0043] When using the independent support of the construction joint and post-casting strip in this case, the specific operation steps are as follows:

[0044] 1. Install support base 1:

[0045] First, the support base 1 is fixedly installed on the ground of the construction site to ensure that it is stable and does not move.

[0046] 2. Adjust the support height:

[0047] The operator controls the heavy sleeve 3 to move up and down along the thread of the threaded support structure 2 by rotating the positioning clamp 4 on the ground, thereby adjusting the overall height of the support rod 5. Since the threaded structure is located at the bottom, there is no need to climb high for adjustment, and the operation is convenient and safe.

[0048] 3. Confirm support stability:

[0049] After adjusting to the desired height, tighten the positioning snap ring 4 to ensure that it is tightly engaged with the threaded rod 23, fixing the position of the heavy sleeve 3 to prevent it from sliding.

[0050] 4. Expand the auxiliary support leg 6:

[0051] If additional stability is needed, the operator can unfold the three sets of auxiliary support legs 6, fix their supports to the outside of the support rod 5, and adjust the length of the legs to provide additional support.

[0052] 5. Check support rod 5:

[0053] Ensure that the sliding rod 53 slides smoothly inside the stabilizing slide 24, check whether the supporting cylinder 51 and the supporting frame 54 are stable, and ensure that the entire device is not shaking.

[0054] 6. Complete the construction:

[0055] After the support device is adjusted, the construction operation is carried out. After the construction is completed, the device can be loosened by rotating the positioning clamp 4 in the opposite direction, and the support device can be disassembled for subsequent use.

[0056] In summary, this case significantly improves the operational convenience, stability, load-bearing capacity and safety of the construction support device through multiple optimization designs of the threaded support structure and support rods. Compared with the existing technology, the innovation of this case greatly improves the efficiency and safety of the construction process and has broad application prospects.

[0057] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
