Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a quick-release support structure. Background Technology

[0002] Currently, most building construction utilizes cast-in-place concrete structures. The formwork structure used in construction mainly consists of three parts: panels, supporting structures, and connectors. The panels are the load-bearing slabs that directly contact the cast-in-place concrete; currently, wooden formwork is commonly used for the panels. The supporting structure is a temporary structure that supports the panels, concrete, and construction loads, ensuring the formwork structure is firmly assembled and does not deform or break. Connectors are the fittings that connect the panels and supporting structures into a whole. Existing wooden formwork support systems cannot achieve early removal functionality with their top supports and back ribs; they require the horizontal structure to reach a certain strength before being completely removed. Furthermore, the existing support top supports bear stress through the structure, formwork, main back ribs, secondary back ribs, top supports, and uprights, resulting in complex stress distribution and making quick removal impossible.

[0003] Therefore, how to provide a quick-release support structure that simplifies the installation process has become a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention discloses a quick-release support structure, and specifically discloses the following technical solutions:

[0005] A quick-release support structure includes a template, a keel, a locking pin, a quick-release top support, and a vertical pole. The template is rectangular with an L-shaped locking plate on its surface edge. The keel is hollow with a positioning groove on its surface. The L-shaped locking plate is inserted into the positioning groove, and the L-shaped locking plate and the keel are respectively provided with through-hole elliptical keyholes. The locking pin passes through the elliptical keyholes, securing the template and the support together. The quick-release top support is located at the top of the vertical pole and includes a support screw, an adjusting ring, and a bracket. The bottom of the support screw extends into the vertical pole. The adjusting ring is located on the surface of the support screw and threadedly connected to it for adjusting and limiting the support screw. The bracket is rotatably located at the top of the support screw and is snapped into the keel.

[0006] Furthermore, the locking pin has limiting protrusions at both ends, and after the locking pin extends into the elliptical keyhole, the limiting protrusions can be engaged with the two ends of the outer side of the elliptical keyhole.

[0007] Furthermore, the top two sides of the bracket are L-shaped, and a rotating locking mechanism is provided in the middle of the bracket, which can lock the bracket together with the keel.

[0008] Furthermore, the rotary locking mechanism includes a tension spring, a sliding block, and a limiting block. The tension spring is disposed inside the bracket. The sliding block is movably confined within the bracket and fixedly connected to the tension spring. The limiting block is disposed at the top of the sliding block and has a flat T-shaped structure. The cylindrical surface of the bracket is provided with a U-shaped through hole. The surface of the sliding block is provided with a toggle rod, which is slidably disposed in the U-shaped through hole.

[0009] Furthermore, a thrust bearing is provided at the bottom end of the bracket, and the support screw is rotatably connected to the bracket through the thrust bearing.

[0010] Furthermore, the L-shaped lock plate is also provided with a handle, which is located on the other side of the vertical plate of the L-shaped lock plate.

[0011] Furthermore, a base is provided at the bottom of the upright, and a height adjustment mechanism is provided on the surface of the upright.

[0012] Furthermore, a disc buckle is provided in the middle of the upright, and a fixed crossbar is provided between adjacent uprights through the disc buckle.

[0013] The beneficial effects of this invention are as follows: By using a combination of template and keel, along with an elliptical keyhole and locking post, this invention eliminates the need for tightening bolts, enabling rapid splicing and installation of the template and keel, simplifying the template laying method. The rotating locking mechanism allows for locking the quick-release top support to the keel via a limiting block, achieving rapid keel positioning. Furthermore, the quick-release top support can be rapidly disassembled by pushing the lever, improving the disassembly efficiency of the support structure. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1

[0023] See attached document Figure 1-6 This embodiment discloses a quick-release support structure, including a template 1, a keel 2, a locking column 3, a quick-release top support, and a vertical pole 4.

[0024] Template 1 has a rectangular structure. The surface edge of template 1 is provided with an L-shaped locking plate 5. The vertical plate of the L-shaped locking plate 5 is provided with an oval keyhole for locking template 1. A handle 6 is provided on one side of the vertical plate for easy handling and installation of template 1.

[0025] The keel 2 is a hollow alloy frame structure. The surface of the keel 2 is provided with a positioning groove, and the side of the keel 2 is provided with a through oval keyhole. The oval keyhole is connected to the positioning groove. When the L-shaped lock plate 5 is inserted into the positioning groove, the oval keyholes of the two overlap. Preferably, the oval keyholes are arranged in pairs to facilitate the quick-release top support. The two ends of the lock pin 3 are provided with limit protrusions. After the lock pin 3 is inserted into the oval keyhole, the limit protrusions can be locked on the two ends of the outer side of the oval keyhole.

[0026] The quick-release top support is located at the top of the upright 4. The quick-release top support includes a support screw 7, an adjusting ring 8, and a bracket 9. The bottom of the support screw 7 extends into the upright 4. The adjusting ring 8 is located on the surface of the support screw 7 and is threadedly connected to the support screw 7 for adjusting and limiting the support screw 7. The bracket 9 is located at the top of the support screw 7. The bottom end of the bracket 9 is provided with a thrust bearing 10. The support screw 7 and the bracket 9 are rotatably connected through the thrust bearing 10 to prevent the rotation of the support screw 7 from affecting the bracket 9 when adjusting the height. The top two sides of the bracket 9 are L-shaped to support the keel 2.

[0027] As a preferred embodiment of the present invention, a rotating locking mechanism is provided in the middle of the bracket 9, which can lock the bracket 9 and the keel 2 together.

[0028] Specifically, the rotating locking mechanism includes a tension spring 11, a sliding block 12, and a limiting block 13. The tension spring 11 is located inside the bracket 9 and is in a stretched state. The sliding block 12 is movably confined in the bracket 9 and fixedly connected to the tension spring 11. The limiting block 13 is fixed to the top of the sliding block 12. The limiting block 13 has a flat T-shaped structure and a limiting groove is provided on the top of the limiting block 13. The cylindrical surface of the bracket 9 is provided with a U-shaped through hole. The surface of the sliding block 12 is provided with a toggle rod 14, which is slidably disposed in the U-shaped through hole.

[0029] In normal conditions, the limiting block 13 is hidden in the bracket 9 under the tension of the tension spring 11. When the bracket 9 needs to be fixed to the keel 2, simply push the lever 14 upward along the U-shaped through hole on the cylindrical surface so that the top of the limiting block 13 passes through the adjacent locking pin 3. Then continue to rotate the lever 14 along the through hole on the cylindrical surface so that the limiting block 13 rotates 90°. Release the lever 14, and the lever 14 slides downward along the U-shaped through hole so that the limiting groove at the top of the limiting block 13 engages with the locking pin. After the bracket 9 is fixed to the keel 2, adjusting the height of the quick-release top bracket will not affect the connection between the top bracket and the keel 2. Furthermore, after the bracket 9 is fixed to the keel 2, the locking pin 3 is further locked to prevent the locking pin 3 from moving. When it is necessary to partially remove the uprights and quick-release top supports, simply push the lever 14 in the opposite direction within the U-shaped through hole. Removing the quick-release top supports will not affect the splicing of the keel 2 to the template 1, thus achieving quick removal of the uprights 4.

[0030] The bottom of the upright 4 is provided with a base 15 for stable support of the upright 4. The surface of the upright 4 is provided with a height adjustment mechanism 16 for adjusting the height of the upright 4. The middle of the upright 4 is provided with a disc buckle 17. The connected uprights 4 are provided with a fixed crossbar through the disc buckle 17 to improve the stability of the support structure.

[0031] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
