Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a quick-release support structure for prefabricated composite floor slabs. Background Technology

[0002] Prefabricated composite floor slabs are prefabricated in the factory and transported directly to the construction site for installation. At the construction site, the prefabricated composite floor slabs are hoisted down to the installation area on the floor for positioning and installation. Support columns and beams are installed beneath the prefabricated composite floor slabs, with the top of the beams supporting the bottom of the slab. During hoisting and movement, it is difficult to effectively guide and vertically align the prefabricated composite floor slabs towards the top of the beams. This results in the prefabricated composite floor slabs not being stably aligned and positioned on top of the beams, causing misalignment and displacement of the connection support area between the prefabricated composite floor slabs and the beams. This affects the stability of the beams and support columns supporting the floor slabs from below, impacting work efficiency. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a quick-release support structure for prefabricated composite floor slabs, which has the characteristics of improving support effect and improving work efficiency.

[0004] The technical solution adopted to solve the above-mentioned technical problems is: a prefabricated composite floor slab quick-release support structure, including a support column, a bracket fixedly connected to the top of the support column, a top beam engaged with the top of the bracket, and a template guiding component, the template guiding component including a rotation drive, a winding belt, a guide plate and a support block, the rotation drive winding the winding belt below the bracket to control the vertical movement of the guide plate and the support block on the side of the top beam; and a positioning component, the positioning component being positioned on the side of the bracket to connect to the template guiding component, the positioning component including a fixed shell and a guide shell, the fixed shell being fixed to the bottom of the bracket and the guide shell being fixed from below the guide shell on the outside of the top beam to constrain and guide the vertical movement of the guide plate from the outside of the guide plate.

[0005] The outer wall of the fixed shell of this utility model is fixedly connected to two symmetrically distributed connecting blocks, and the guide shell is fixedly connected between the two connecting blocks.

[0006] The rotation drive component of this utility model is fixedly connected to the outer wall of the fixed shell, and the output end of the rotation drive component is rotatably connected to the inside of the fixed shell.

[0008] The guide plate of this invention is inserted into the inner side of the guide shell, and the inner sidewall of the guide plate contacts the corresponding end of the top beam.

[0009] The top beam of this utility model has a guide groove at the end corresponding to the guide plate, and the support block is inserted into the guide groove.

[0010] The fixed shell of this utility model has an arc plate fixedly connected inside, and the outer wall of the winding tape is close to the inner wall of the arc plate.

[0011] 1. This utility model uses support columns to position the bracket, top beam, template guiding component, and positioning component together in the floor slab installation area. The top beam aligns with the bottom of the installation area, and the guiding plate and support block extend upwards to the top of the installation area. During the descent of the prefabricated composite floor slab, the guiding plate adheres closely to the corresponding side of the floor slab, and the top of the support block supports the bottom of the floor slab, effectively aligning the descending prefabricated composite floor slab in the installation area. During the descent, the guiding plate and support block move downwards along with the floor slab. Multiple support devices installed within the floor can effectively guide and align the floor slab above the top beam from all four sides, effectively guiding the prefabricated composite floor slab towards the top beam for vertical alignment, ensuring stable alignment and positioning of the prefabricated composite floor slab on the top beam, and improving the stability of the prefabricated composite floor slab positioning, installation, and support.

[0012] 2. In this utility model, the guide plate and support block can be moved downward to the lower position of the installation area, separating the guide plate and support block from the prefabricated composite floor slab, and retracting the guide plate and support block into the side position of the top beam, so that the whole device is kept in the state of supporting the floor slab from below, so as to facilitate the subsequent fixing work of the floor slab. The top beam can move vertically below the floor slab together with the template guide component and the positioning component through the support column, so as to facilitate the removal of the whole device below the floor slab. It can conveniently carry out the guiding, splicing, alignment, support and removal work of the whole device below the floor slab, improving work efficiency.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to these embodiments. Example 1

[0017] exist Figures 1-4 This utility model relates to a prefabricated composite floor slab quick-release support structure, including a support column 1, a bracket 11 fixedly connected to the top of the support column 1, a top beam 12 snapped onto the top of the bracket 11, and a template guiding component 2. The template guiding component 2 includes a rotation drive 21, a winding belt 22, a guide plate 23, and a support block 24. The rotation drive 21 winds up the winding belt 22 below the bracket 11 to control the vertical movement of the guide plate 23 and the support block 24 on the side of the top beam 12. A positioning component 3 is positioned on the side of the bracket 11 to connect to the template guiding component 2. The positioning component 3 includes a fixing shell 31 and a guide shell 32. The guide shell 32 is positioned on the outside of the top beam 12 through the fixing shell 31 to constrain and guide the vertical movement of the guide plate 23 from the outside.

[0018] In this embodiment, the support column 1, bracket 11, top beam 12, template guiding component 2, and positioning component 3 work together to form a floor slab support device. The bracket 11 is fixed to the top of the support column 1, and the top beam 12 is connected to the top of the bracket 11 by a snap-fit ​​method. The four upright corners of the top of the bracket 11 block and constrain the top beam 12 from the outside. The bracket 11 is controlled by the support column 1 to move vertically together with the top beam 12. The support column 1 adopts an existing adjustable steel support. This type of adjustable steel support adopts a galvanizing process and supports telescopic adjustment. Common models include independent columns with a diameter of 48 / 56mm, so as to facilitate the adjustment of the position of the top beam 12 and the bracket 11.

[0019] The positioning component 3 is located on the side of the bracket 11. The positioning component 3 is used to connect the template guiding component 2 to the side of the bracket 11 and the top beam 12. The positioning component 3 consists of a fixed shell 31 and a guide shell 32. The fixed shell 31 is fixedly connected to the bottom of the bracket 11, and two symmetrically distributed connecting blocks 33 are fixedly connected to the outer wall of the fixed shell 31. The guide shell 32 is fixedly connected between the two connecting blocks 33, so that the positioning component 3 is stably connected to the side of the bracket 11 as a whole, and the guide shell 32 is stably positioned on the outside of the top beam 12 by the two connecting blocks 33 and the fixed shell 31.

[0020] The template guiding assembly 2 consists of a rotating drive 21, a take-up belt 22, a guide plate 23, and a support block 24. The rotating drive 21 is fixedly connected to the outer wall of the fixed shell 31, and the output end of the rotating drive 21 is rotatably disposed inside the fixed shell 31. The tail end of the take-up belt 22 is fixedly connected to the output end of the rotating drive 21. In this embodiment, the rotating drive 21 is a motor. The guide plate 23 is fixedly connected to the head end of the take-up belt 22, and the support block 24 is fixedly connected to the inner side wall of the guide plate 23. The template guiding assembly 2 is stably connected to the outside of the bracket 11 to position the guide plate 23 and the support block 24 on the outside of the top beam 12. The rotation drive 21 activates the winding tape 22, which pulls the guide plate 23 and the support block 24 to move vertically. The guide plate 23 is inserted into the inner side of the guide shell 32, and the inner wall of the guide plate 23 contacts the corresponding end of the top beam 12. The top beam 12 has a guide groove 121 at the end corresponding to the guide plate 23, and the support block 24 is inserted into the guide groove 121, allowing the guide plate 23 and the support block 24 to move vertically at the corresponding end of the top beam 12. This facilitates changing the position of the guide plate 23 and the support block 24, allowing them to be completely retracted into the top beam 12. An arc plate 34 is fixedly connected inside the fixed shell 31. The outer wall of the winding tape 22 is pressed against the inner wall of the arc plate 34, ensuring that the winding tape 22 remains in contact with the arc plate 34 during winding, thereby improving the stability of the winding tape 22 and the movement of the guide plate 23. The take-up belt 22 can be made of spring steel sheet or spring steel strip. Spring steel sheet or spring steel strip has elastic memory function and is often used in measuring tape. Therefore, it can overcome the gravity of the guide plate 23 and always stay in a specific position.

[0021] The positioning component 3 is combined with the template guide component 2 and connected to the bracket 11. The template guide component 2 is positioned as a whole on the outer side of the corresponding end of the top beam 12. The support column 1 positions the bracket 11, the top beam 12, the template guide component 2 and the positioning component 3 together in the floor slab installation area on the floor. The top beam 12 is aligned with the bottom of the installation area. The guide plate 23 and the support block 24 extend upward to the upper position of the installation area. The guide plate 23 is close to the corresponding side of the floor slab during the descent of the prefabricated composite floor slab. The top of the support block 24 supports the bottom of the floor slab to effectively connect the descending prefabricated composite floor slab in the installation area. During the descent of the floor slab, the guide plate 23 and the support block 24 move downwards along with the floor slab. Multiple support devices are installed within the floor, and support devices are installed on all four sides of the floor slab. This allows for the simultaneous guidance and alignment of the floor slab above the top beam 12 from all four sides. During the descent, the floor slab is effectively guided to move vertically downwards to approach the top beam 12, facilitating the guidance and vertical alignment of the prefabricated composite floor slab onto the top beam 12. This ensures that the prefabricated composite floor slab is stably aligned and positioned on the top beam 12, preventing misalignment or displacement of the connection support area between the prefabricated composite floor slab and the top beam 12. This improves the stability of the positioning, installation, and support of the prefabricated composite floor slab, and increases work efficiency.

[0022] The guide plate 23 and support block 24 can be moved downwards to a position below the installation area to effectively separate the guide plate 23 and support block 24 from the prefabricated composite floor slab, and to retract the guide plate 23 and support block 24 into the side position of the top beam 12, so that the entire device is kept in a state of supporting the floor slab from below, so as to facilitate the fixing of the floor slab in the installation area. The top beam 12 can move vertically below the floor slab together with the template guide assembly 2 and positioning assembly 3 through the support column 1, so as to dismantle the entire device below the floor slab. The operation is simple and can facilitate the guidance, splicing, alignment, support and dismantling of the device below the floor slab, improving work efficiency.
