Description

Technical Field

[0001] This utility model relates to the field of construction support technology for prefabricated hollow sandwich panels, and in particular to an adjustment device for a temporary support system of prefabricated hollow sandwich panels. Background Technology

[0002] With economic development and improved living standards, people have higher and higher requirements for living space. Ordinary concrete floor slabs can hardly meet the requirements of flexible space, large column grid and large clear height. As the span increases, the self-weight and reinforcement of the floor slab will increase significantly, which not only makes it difficult to meet the large clear height of the structure, but also greatly increases the cost of the structure. Therefore, hollow sandwich slabs with small self-weight and low height have emerged.

[0003] In recent years, hollow sandwich slabs have been widely used in building structures such as factories, houses, museums, and stadiums. The construction of hollow sandwich slabs is mainly divided into cast-in-place, semi-prefabricated, and prefabricated types. Among them, the construction difficulty of semi-prefabricated and prefabricated hollow sandwich slabs is greatly reduced compared with cast-in-place reinforced concrete hollow sandwich slabs, and the formwork required for construction is also greatly reduced.

[0004] To facilitate the assembly of prefabricated hollow sandwich panels, a support system is needed for temporary support on the construction site.

[0005] The existing patent document with publication number CN221682579U discloses a temporary support bracket for prefabricated buildings. The positioning ring is driven by a first spring, which allows the positioning ring to be inserted into or detached from the fixed base. This allows the connecting sleeve rod and the support slide rod to be vertically installed on the base plate to support the prefabricated building components or to be laid down on the base plate, reducing the occupied area and making it easier to store and carry.

[0006] Although the aforementioned temporary support brackets for prefabricated buildings can solve the corresponding technical problems, the contact area between the support slide and the prefabricated building components remains fixed, the support range is small, and the scope of application is limited. It can also easily lead to excessive stress on a single point of the prefabricated building components.

[0007] To address this, a prefabricated hollow sandwich panel temporary support system adjustment device is proposed. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-3 This utility model provides an adjustment device for a temporary support system of a prefabricated hollow sandwich panel, including a support component 100 located at the output end of a support cylinder 1 and capable of contacting the prefabricated hollow sandwich panel, an extension component 200 for adjusting the contact area of ​​the support component 100, a diagonal brace 300 for providing auxiliary support to the extension component 200, and a connecting component 400 for connecting and adjusting the usage state of the extension component 200. An extension component 200 is provided on each side of the support component 100, and two connecting components 400 are arranged vertically on the support component 100, with each connecting component 400 corresponding to one of the extension components 200. A diagonal brace 300 is provided between each connecting component 400 and its corresponding extension component 200. The two extension components 200 have the same structural shape, with one diagonal brace 300 having a longer length than the other diagonal brace 300. The upper connecting component 400 is connected to the shorter diagonal brace 300, and the lower connecting component 400 is connected to the longer diagonal brace 300.

[0030] The support assembly 100 includes a support rod 110 installed at the output end of the support cylinder 1. A support plate 120 is fixedly connected to the top of the support rod 110. Two extension components 200 are respectively located on both sides of the support plate 120. Installing the support assembly 100 at the output end of the support cylinder 1 can further increase the support height of the support cylinder 1. When not in use, the support assembly 100 can be separated from the support cylinder 1 for transportation. At the same time, the support assembly 100 can provide an installation base for the extension components 200, the diagonal brace 300, and the connecting component 400.

[0031] The expansion component 200 includes an expansion plate 210 rotatably connected to the side of the support plate 120 via a pivot. The surface of the expansion plate 210 has a groove 220 that works with the diagonal brace 300. By rotating the expansion component 200, the expansion component 200 is made to be horizontal, so that the support plate 120 and the expansion plate 210 are on the same plane. This increases the contact area between the support component 100 and the prefabricated hollow sandwich panel, avoiding excessive stress on a single point of the prefabricated hollow sandwich panel. It also allows the number of expansion components 200 used to be determined according to the actual usage, avoiding affecting the installation of other equipment.

[0032] One end of the diagonal brace 300 passes through the inner cavity of the corresponding groove 220 and is rotatably connected to the extension plate 210 via a pivot. The other end of the diagonal brace 300 is located on the connecting component 400. The diagonal brace 300 can provide auxiliary support for the extension component 200. When the extension plate 210 is in a horizontal state, the diagonal brace 300, the extension plate 210, and the support rod 110 can form a right-angled triangle structure, which has great stability and better reliability, thereby helping to improve the support effect of the extension component 200.

[0033] The connecting component 400 includes a connector 410 movably disposed on the surface of the support rod 110. The end of the diagonal brace 300 away from the extension plate 210 is movably connected to the corresponding connector 410. A rotating component 420 is provided between the connector 410 and the support rod 110.

[0034] The connector 410 includes an outer hoop 411 that is movably fitted onto the surface of the support rod 110 and has an arc-shaped structure. Both ends of the outer hoop 411 are integrally formed with a side ear 412, and a gap is formed between the two side ears 412. The end of the diagonal brace 300 away from the extension plate 210 passes through the gap and is rotatably connected to the side ear 412 through a pivot. When the extension component 200 is flipped upward to a horizontal state or flipped downward to a vertical state, the extension component 200 can drive one end of the diagonal brace 300 to move synchronously. Since the length of the diagonal brace 300 remains unchanged, the angle of the diagonal brace 300 changes, so that the other end of the diagonal brace 300 can drive the connector 410 to move up and down on the surface of the support rod 110, which can guide the diagonal brace 300 and help improve the stability of the diagonal brace 300 during movement.

[0035] The rotating component 420 includes an inner tube 421 located between the support rod 110 and the outer clamp 411. The inner wall of the inner tube 421 is provided with internal threads, and the surface of the support rod 110 is provided with three external threads from top to bottom. The inner tube 421 is threadedly connected to the support rod 110 through the mating of the internal and external threads. Two symmetrically arranged handles 422 for easy force application are fixedly connected to the surface of the inner tube 421. The rotating component 420 can achieve the positioning function of the connecting component 410, so that the connecting component 410 can be stably placed at a certain position on the support rod 110. To ensure that the extension component 200 can always remain in a horizontal or vertical state and avoid collapse; at the same time, a three-section external thread is adopted. When the extension component 200 is in a horizontal state, the upper two sections of external thread can be used to position the connector 410; when the extension component 200 is in a vertical state, the lower two sections of external thread can be used to position the connector 410. This allows the rotating component 420 to slide directly on the support rod 110 after disengaging from one of the external threads, without the need for continuous rotation, which helps to reduce labor intensity and improve adjustment efficiency.

[0036] The outer hoop 411 has an integrally formed arc-shaped protrusion 413 on its inner wall surface. The inner tube 421 has an annular groove 423 that matches the protrusion 413 on its surface. The inner wall surface of the annular groove 423 is slidably connected to the surface of the protrusion 413. Through the cooperation of the protrusion 413 and the annular groove 423, the outer hoop 411 and the inner tube 421 can be movably connected to each other, so as to ensure that the inner tube 421 can rotate normally on the surface of the support rod 110 without affecting the connection effect between the connector 410 and the diagonal brace 300.

[0037] A retaining ring 500 is fixedly sleeved on the upper part of the surface of the support rod 110. The retaining ring 500 is located above the external thread. The top of the inner tube 421 located above contacts the bottom of the retaining ring 500. The opposite ends of the two inner tubes 421 are in contact. When the inner tube 421 located above is fixed to the support rod 110 through the uppermost external thread, the retaining ring 500 can restrict the inner tube 421 and prevent the inner tube 421 from moving excessively. When the inner tube 421 located above moves to its maximum extent, it can drive the extension component 200 to a horizontal state.

[0038] The handle 422 has an anti-slip texture on its surface, which is a wavy texture, to increase the friction when the operator holds it.

[0039] The working principle of this utility model is as follows: The support assembly 100 is installed at the output end of the support cylinder 1. Activating the support cylinder 1 causes the support assembly 100 to move upwards until the top of the support plate 120 contacts the prefabricated hollow sandwich panel, thus achieving temporary support for the prefabricated hollow sandwich panel. Using the handle 422, the inner tube 421 located above is rotated, causing the inner tube 421 to rotate the annular groove 423. Under the action of the thread, the inner tube 421 moves upwards on the surface of the support rod 110. The inner tube 421 drives the outer hoop 411, side ears 412, and protrusions 413 to move upwards simultaneously. The protrusions 413 move upwards in the annular groove... The inner cavity of 423 slides, and the side ear 412 drives one end of the diagonal brace 300 to move synchronously. The other end of the diagonal brace 300 pushes the extension plate 210 to flip upward. When the inner tube 421 disengages from the external thread in the middle, the inner tube 421 can be moved directly upward until it is close to the external thread at the top. Then, the inner tube 421 is rotated until the top of the inner tube 421 contacts the bottom of the retaining ring 500. At this time, the extension plate 210 is in a horizontal state, which realizes the adjustment of the support area of ​​the assembled hollow sandwich panel. Similarly, by using the handle 422 to rotate the inner tube 421 located below, the other extension plate 210 can be adjusted to a horizontal state to expand the support area.

[0040] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
