Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an auxiliary device for simultaneously pouring concrete for two floor slabs. Background Technology

[0002] During the construction of concrete structures, there is a lack of convenient and reliable methods for erecting formwork to simultaneously pour concrete in overlapping sections of floor slabs in the main structure. These overlapping areas are usually small, but the inability to pour concrete simultaneously significantly impacts the construction progress of the main structure.

[0003] Utility model patent CN214942359U discloses a support for simultaneous pouring of partially overlapping floor slabs. It includes a first support plate, a second support plate located below the first support plate, a frame for supporting the non-overlapping portions of the first and second support plates, and a support mechanism for supporting the overlapping portions of the first and second support plates. The support mechanism includes a first screw rod that passes through the second support plate from top to bottom and is fixedly connected to the first support plate, and two sleeves that are sleeved and threadedly connected to the first screw rod. The inner sidewalls of the sleeves are threaded. The sleeves are threadedly connected to the first screw rod and respectively abut against both sides of the second support plate. The end of the first screw rod away from the first support plate abuts against the ground through a support leg assembly.

[0004] The aforementioned patent enables simultaneous pouring of concrete for upper and lower floor slabs, but the pallets, frames, and fixing bolts used in this solution are unconventional frame materials that cannot be reused, and the actual use requires high material performance. Utility Model Content

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] like Figure 1 and Figure 2 As shown, this utility model discloses an auxiliary device for simultaneous pouring of concrete for two floor slabs, comprising a first frame 1 and a second frame 2 arranged vertically. The top of the first frame 1 is provided with a template 3. The second frame 2 includes vertically arranged connecting pipes 4. Above the template 3, there is a connecting mechanism 5 corresponding to each connecting pipe 4. The connecting mechanism 5 includes a base 6. The base 6 is provided with a boss 7. The boss 7 and the upper surface of the base 6 are rounded. The boss 7 is provided with an installation groove 8. Above the installation groove 8, there is a connecting column 9. The bottom of the connecting column 9 is provided with a connector 10 that cooperates with the installation groove 8. The outer surface of the connecting column 9 is provided with a threaded section 11. The top of the connecting column 9 is coaxially provided with a hexagonal insert rod 12. The insert rod 12 and the connecting column 9 form a limiting platform 13. The lower surface of the connecting pipe 4 abuts against the limiting platform 13.

[0020] The first scaffold 1 and the second scaffold 2 are both standard scaffolding structures, consisting of horizontal and vertical steel pipes connected by cross joints to form a grid-like support frame. The top of the first scaffold 1 is fixed with a formwork 3 to support the upper floor concrete slab; the steel pipes of the second scaffold 2 opposite the formwork 3 form connecting pipes 4. The base 6 is made of steel and is integrally formed with the boss 7 through forging. The diameter of the base 6 is larger than that of the boss 7 to increase the load-bearing area and improve stability. The mounting groove 8 is hemispherical with a central angle of 150°-160°, and the connector 10 is a matching hemispherical shape. The gap between the two is controlled at 0.1mm-0.3mm to ensure precise alignment and allow for minor deformation buffering; the upper surface of the boss 7 and the base 6 has a rounded transition, facilitating the demolding of the subsequent concrete layer 17. During the pouring process, the thickness of the concrete layer 17 does not exceed the overall height of the base 6, the boss 7, the connector 10, and the connecting column 9; the diameter of the connecting column 9 is greater than the diameter of the connecting pipe 4, and a threaded section 11 is provided on the connecting column 9. The length of the threaded section 11 extending along the axial direction of the connecting column 9 is the same as the length of the connecting column 9, and the pitch of the threaded section 11 is 1-2 cm; the connecting pipe 4 is sleeved on the insertion rod 12 and abuts against the limiting platform 13.

[0021] During the pouring of concrete layer 17, the first scaffold 1 is erected first, and the first layer of formwork is installed above the first scaffold 1. Connecting mechanisms 5 are arranged in a row above the first layer of formwork, and connecting pipes 4 are inserted into each connecting mechanism 5. The connecting pipes 4 serve as the longitudinal steel pipes of the second scaffold 2. Then, transverse steel pipes are laid on the longitudinal steel pipes to achieve the overlap of the second scaffold 2. The second layer of formwork is installed above the second scaffold 2, so that concrete can be poured on the first and second layer of formwork at the same time. After the concrete layer 17 is cured, the first scaffold 1, the second scaffold 2 and the formwork 3 are removed. The base 6 and the boss 7 are taken out from below the concrete layer 17. The insert rod 12 has a hexagonal cross-section design. Using an internal hex wrench on the insert rod 12, rotating the internal hex wrench, under the action of the threaded section 11, the connecting column 9 can be taken out from the concrete layer 17 from above, realizing the reuse of materials.

[0022] To ensure the stability of the base 6 on the template 3, a base plate 14 is further provided below the base 6, and a release layer 15 is provided on the upper surface of the base 6. The base plate 14 is made of rubber or silicone and is bolted or bonded to the base 6. Anti-slip protrusions can be provided on the lower surface of the base plate 14 to make the base 6 more stable on the template 3. Simultaneously, to facilitate demolding, a release layer 15 is provided on the upper surface of the base 6. A polytetrafluoroethylene coating is applied to cover the upper surface of the base 6 using a spraying process, with a uniform thickness of 0.5mm-1mm, reducing concrete adhesion.

[0023] To better separate the concrete layer 17 from the base 6 after the concrete layer 17 has cured, a rotating hole 16 is provided on the lower surface of the base 6. The rotating hole 16 has an internal hexagonal cross-section. By inserting a hexagonal wrench into the rotating hole 16 and rotating the base 6, the base 6 can be separated from the concrete layer 17.

[0024] Since the upper surface of template 3 may have an angle with the horizontal plane, further see... Figure 2 and Figure 3 The mounting groove 8 is hemispherical, and the central angle corresponding to the mounting groove 8 is between 150° and 160°. This arrangement allows the connector 10 to rotate within the mounting groove 8, keeping the connecting post 9 in a vertical position.

[0025] To prevent the connecting pipe 4 from sliding on the upper surface of the limiting platform 13, the upper surface of the limiting platform 13 is further provided with anti-slip texture.

[0026] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
