Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically, it is a secondary structural column formwork support device that does not require drilling. Background Technology

[0002] With the rapid development of construction engineering, industry professionals have become increasingly strict in their quality requirements for building construction projects. Secondary structural columns are widely used in building structures, and on-site technicians have also raised their requirements for the quality of pouring and the formwork system. They not only need to reduce costs and increase efficiency, save materials and protect the environment, but also ensure that the quality is up to standard. Therefore, the formwork reinforcement of secondary structural columns is a challenge for on-site construction.

[0003] Traditional formwork reinforcement for structural columns employs two methods: step-by-step tightening with building tools and tie rod installation. While step-by-step tightening is convenient and quick, it leaves holes in the wall, potentially compromising the structural integrity. Using tie rods requires drilling holes in the formwork, leaving openings in the structural column. For rooms exposed to water, these holes need to be sealed later, wasting manpower and resources. Furthermore, both of these secondary formwork reinforcement methods involve hammering and vibrating the concrete after pouring, or using a vibrator for layered compaction, resulting in complex and uninterrupted construction procedures.

[0004] Chinese patent CN105604339B, published on December 15, 2017, discloses a method for reinforcing secondary structural columns. This invention involves welding horizontal tie bars to the through-wall tie rods of the structural column, and using butterfly buckles to lock the steel pipes of the reinforcing timber back braces at the end of the structural column. The tension of the horizontal tie bars provides the necessary horizontal constraint for the column end reinforcement, avoiding the drawbacks of reduced wall integrity and compressive strength caused by drilling holes in the structural column formwork. Although this invention avoids drilling holes in the wall, the reinforcement method still uses traditional vibration compaction and requires drilling holes in the formwork with tie rods, necessitating subsequent sealing of these holes.

[0005] Chinese patent CN217175711U, published on August 12, 2022, discloses an openable aluminum formwork for structural columns. This invention includes three aluminum formwork panels located on the front and rear sides between two masonry walls. Multiple protrusions are integrally formed on opposite sides of the two masonry walls, abutting against the aluminum formwork panels. A concrete grouting groove is provided at the top of the front top aluminum formwork panel. This invention can avoid concrete quality problems in structural columns such as "rotten roots," "broken strips," and "honeycomb and pitted surfaces." However, it requires opening the aluminum formwork multiple times, making the process complex.

[0006] Therefore, the known secondary structural column formwork reinforcement methods have the aforementioned inconveniences and problems. Utility Model Content

[0007] The purpose of this utility model is to propose a safe and reliable secondary structural column formwork support device that does not require drilling.

[0008] To achieve the above objectives, the technical solution of this utility model is: A secondary structural column drill-free formwork support device, comprising aluminum formwork, sliding guide rails, and jacks, characterized in that: The aluminum formwork 1 consists of two rectangular aluminum formwork pieces that cooperate with each other. The bottom ends of the two rectangular aluminum formwork pieces are clamped to both sides of the wall 10. A limiting groove 2 is provided in the middle of the top of the two rectangular aluminum formwork pieces. A concrete pouring port 3 is provided at the upper end of one formwork piece. A concrete vibrator 9 is provided in the middle of one formwork piece through a fixed bracket 6. The sliding guide rail 12 consists of a pair of parallel steel rails spaced apart and perpendicular to the aluminum template facade. One end of the sliding guide rail 12 is connected to the aluminum template via a limiting support 11, and the other end of the sliding guide rail 12 is provided with a support rod 4. The support rod is connected and fixed via a support crossbar 5, so that one end of the support crossbar supports the aluminum template via a support tray 8. The base of the sliding guide rail 12 is provided with several lower limiting bolt holes 13. A slide block is provided above the sliding guide rail 12 and moves in conjunction with the sliding guide rail base. The upper center of the slide block is provided with an upper limiting bolt hole 14, and the sides of the slide block are provided with jack lower support bolt holes 15. The jack 7 is a small jack. The base of the jack is provided with a jack upper support bolt hole 16. The jack is connected and fixed to the jack lower support bolt hole 15 by bolts.

[0009] The secondary structural column punch-free formwork support device of this utility model can also be further realized by the following technical measures.

Detailed Implementation

[0015] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0016] Example 1 This utility model discloses a secondary structural column support device without drilling, which includes aluminum formwork, sliding guide rails, and jacks.

[0017] The aluminum formwork 1 consists of two rectangular aluminum formwork panels that fit together. The bottom ends of the two rectangular aluminum formwork panels are clamped to both sides of the wall 10. A limiting groove 2 is provided in the middle of the top of the two rectangular aluminum formwork panels. A concrete pouring port 3 is provided at the upper end of one formwork panel, and a concrete vibrator 9 is provided in the middle of the formwork panel through a fixed bracket 6. Preferably, the splicing edges of the aluminum formwork 1 can be provided with reinforcing ribs to further improve the stability and deformation resistance of the formwork during the load-bearing process.

[0018] The sliding guide rail 12 consists of a pair of parallel steel rails spaced apart and perpendicular to the aluminum template facade. One end of the sliding guide rail 12 is connected to the aluminum template via a limiting support 11, and the other end of the sliding guide rail 12 is equipped with a support column 4. The support column is connected and fixed via a support crossbar 5, with one end of the support crossbar supporting the aluminum template via a support tray 8. The base of the sliding guide rail 12 has several lower limiting bolt holes 13. A slide block is movably mounted above the sliding guide rail 12 in conjunction with the sliding guide rail base. The upper center of the slide block has an upper limiting bolt hole 14, and both sides of the slide block have jack lower support bolt holes 15. Furthermore, the slide block and the sliding guide rail 12 can slide smoothly together via a limiting block and a wear-resistant bushing to prevent shaking and wear under load.

[0019] The jack 7 is a small jack, and its base has upper support bolt holes 16. Bolts are used to connect and fix the jack to the lower support bolt holes 15. The slide block can slide on the sliding guide rail base. The vibrator 9 is connected to the fixed bracket 6 and can move freely up and down. Preferably, after the jack 7 is adjusted to the target position, it can be limited by locking nuts or slots to prevent slippage caused by vibration or load during construction.

[0020] Please see now Figures 1-3 The secondary structural column no-drill formwork support device of this utility model comprises four components: Part 1: Using bolts, the jack support is connected and fixed to the platform of the lower sliding guide rail through the pre-drilled bolt holes on the device to prevent relative slippage. The jack and the connecting platform can move freely in the direction perpendicular to the template. Bolt holes are pre-drilled at both ends of the connecting platform to restrict its displacement and fix the jack's position. Furthermore, thickened sleeves can be provided at the edges of the bolt holes on the connecting platform to improve wear resistance and stability during long-term use.

[0021] The second part includes supporting uprights and supporting horizontal bars. One end of the vertical supporting bar, equipped with a supporting tray, contacts the top slab and is secured by jacks in the aforementioned components, providing sufficient rigidity for the supporting structure. The other end of the horizontal supporting bar, also equipped with a tray, contacts the formwork to increase the contact area, while the other end connects to the supporting upright, thus bearing the load of the concrete through the bars. Preferably, the supporting tray 8 and the supporting horizontal bar 5 can be connected by a threaded detachable connection for easy disassembly and relocation after construction.

[0022] The third part includes a limiting groove at the pouring port, allowing for direct connection between the wedge-shaped pouring port and the formwork during construction. Furthermore, a sealing gasket can be added around the pouring port 3 to prevent concrete slurry leakage during pouring.

[0023] In the fourth part, the vibrator is placed on the fixed support, and the fixed support is connected to the template. This part of the assembly can move up and down along the template. Preferably, the vibrator 9 is connected to the fixed support 6 through a slot-type guide structure, which makes disassembly or replacement easier and improves the applicability of the equipment.

[0024] The device can be adjusted using the above methods to achieve flexible support and reinforcement of the formwork for secondary structural columns, depending on the specific engineering conditions.

[0025] This utility model possesses substantial features and significant technological advancements. The non-drilling formwork support device for secondary structural columns focuses on two main aspects: the non-drilling design for secondary structural columns and the search for efficient vibration methods. This not only improves project quality but also increases work efficiency, saving construction time and costs. Furthermore, all components of this device can utilize commercially available standard parts or be replaced with equivalent components, further ensuring its feasibility and scalability.

[0026] The above embodiments are for illustrative purposes only and are not intended to limit the scope of this utility model. Those skilled in the art can make various modifications and variations without departing from the spirit and scope of this utility model. Therefore, all equivalent technical solutions should also fall within the scope of this utility model and should be defined by the claims.
