Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically to an early-stripping structure for building formwork. Background Technology

[0002] Early stripping formwork technology is an advanced construction process that significantly improves the efficiency of formwork turnover by removing part of the formwork and supports when the concrete structure reaches 50%-70% of its design strength, while retaining key support points for continued curing.

[0003] A typical early-stripping formwork system consists of three main parts: adjustable independent steel supports, a dedicated early-stripping structure, and matching formwork components. The early-stripping head, as the core component, employs a specially designed support mechanism. When the locking device is released, the formwork and joists can drop 5-10cm away from the concrete surface, while the support poles remain in place to continue bearing the structural load.

[0004] However, some early-stripping structures use thin guide fasteners or pins to bear the main load, which poses a risk of the support unit falling off after long-term use. Therefore, there is an urgent need for an early-stripping structure for building formwork to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an early stripping structure for building formwork to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An early stripping structure for building formwork includes two sets of support frames. Each set of support frames includes two support rods. Each support rod includes a steel pipe with protruding ribs on the outside. A support plate is provided at one end of the steel pipe, and a limiting plate is sleeved on the outside of the steel pipe. The limiting plate is provided with grooves and protrusions; the protrusions of the limiting plate are distributed in two ways; One type has bumps distributed around the perimeter of the limiting plate, and the number of bumps is 2-6. Another type has bumps distributed on the bottom outer wall of the limiting plate, and the number of bumps is 2-6; The grooves and protrusions are matched in specifications and correspond one-to-one; The limiting plate includes an early removal section, which can be distributed in two ways. One type is a wedge groove provided on one side of the limiting plate, and the number of wedge grooves needs to match the number of protrusions. The wedge groove includes a horizontal part and an inclined part, and the height of the inclined part is 0.5-3mm. Another type of limiting plate is also provided with a wedge, which also includes a horizontal part and an inclined part.

[0007] Preferably, a first main beam and a secondary beam are provided between the two sets of support frames, with the first main beam located at both ends of the support frame.

[0008] Preferably, the support frame includes a connector that is sleeved on the outside of the steel pipe.

[0009] Preferably, the connector is located above the protruding ridge, and the limiting plate is located below the connector.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-7 As shown, the present invention provides a building formwork early stripping structure, including two sets of support frames 1, each set of support frames including two support rods 5, the support rods 5 including steel pipes 6, the outside of the steel pipes 6 being provided with protruding ribs 7, one end of the steel pipes 6 being provided with a support plate 8, and a limiting plate 10 being sleeved on the outside of the steel pipes 6. The limiting plate 10 is provided with grooves 15 and protrusions 14; the protrusions 14 of the limiting plate 10 are distributed in two ways; In one type, the bumps 14 are distributed around the periphery of the limiting disk 10, and the number of bumps 14 is 2-6. Alternatively, the bumps 14 are distributed on the bottom outer wall of the limiting disk 10, and the number of bumps 14 is 2-6; The groove 15 and the convex ridge 7 are compatible in size and correspond one-to-one; The limit plate 10 includes an early release section, which has two distribution patterns. One type is a wedge groove 11 provided on one side of the limiting plate 10, and the number of wedge grooves 11 matches the number of protrusions 7. The wedge groove 11 includes a horizontal part 13 and an inclined part 12, and the height of the inclined part is 0.5-3mm. Another type of limiting plate 10 is provided with a wedge 19, which also includes a horizontal part 13 and an inclined part 12, with the height of the inclined part being 0.5-3mm.

[0027] In this invention, during operation, the upper edge of the convex ridge rests against the horizontal part of the wedge groove or wedge block of the limiting plate, and the upper load acts on the limiting plate. The limiting plate then transmits the load to the convex ridge through the horizontal part of the wedge groove or wedge block.

[0028] When early disassembly is required, tap the limiting plate to make it rotate. At this time, the top of the convex ridge gradually separates from the horizontal part and contacts the inclined part. During this process, the height of the limiting plate will gradually decrease, and the pressure on the upper part will be gradually released during the descent.

[0029] This utility model discloses a support rod composed of a support plate, a steel pipe, and protruding ribs. The support plate is located at the end of the steel pipe and serves to support the template. The protruding ribs support the limiting disc and are located on the outer wall of the steel pipe, with at least two ribs. The limiting disc is the core component of the early disassembly structure; it is a circular ring structure with an inner diameter slightly larger than the outer diameter of the support rod for easy rotation. It has protrusions and grooves. The protrusions facilitate the operator's rotation of the limiting disc, typically achieved by striking it with a hammer. There are at least two of these protrusions. The grooves need to be coupled with the protruding ribs of the support rod, and their size and number correspond to the protruding ribs on the support rod. To better constrain the protruding ribs and facilitate easier rotation of the limiting disc, wedge-shaped grooves or wedge-shaped protrusions can be provided on the limiting disc.

[0030] The width of the wedge groove or wedge block should be slightly larger than the width of the support column protrusion to fully accommodate the protrusion and prevent stress concentration.

[0031] The wedge groove or wedge block consists of two parts: a horizontal part and an inclined part. When installing the early removal structure, the protruding edge needs to be aligned with the horizontal part of the wedge groove or wedge block.

[0032] When early disassembly is required, tap the limiting plate to make it rotate. At this time, the inclined part of the wedge groove or wedge block and the convex edge come into contact. Since the inclined part is a slope, the height of the limiting plate gradually decreases, and the pressure on the limiting plate gradually decreases, thus making it easier to complete the disassembly.

[0033] Preferably, a first main beam 2 and a secondary beam 3 are provided between the two sets of support frames 1, with the first main beam 2 located at both ends of the support frame 1.

[0034] Preferably, the support frame 1 includes a connector 9, which is sleeved on the outside of the steel pipe 6.

[0035] Preferably, the connector 9 is located above the protrusion 7, and the limiting plate 10 is located below the connector 9. The connector is a component used to connect the main beam in four directions. It has a cubic structure and two connecting holes. The inner diameter of the upper connecting hole is slightly larger than the outer diameter of the support rod, and the lower connecting hole is slightly larger than the outer diameter of the support rod plus the thickness of the two protrusions.

[0036] The two connecting holes are connected by a support wall, which can transfer the upper load to the lower limiting plate. The height of the support wall is the lowering height of the main beam during early dismantling.

[0037] When in use, the connector is mounted on the support rod through the connection hole.

[0038] Preferably, a second main beam 4 is provided between the two support frames 1. The two ends of the second main beam 4 are welded to the connector 9. The main beam is used to directly support the template and is usually made of aluminum alloy. Its cross-section is a hollow rectangle. In addition, a support plate is provided in the middle of its cross-section. The support plate runs through the middle of the main beam and is mainly used to place the secondary beam.

[0039] Preferably, the connector 9 includes a first connecting hole 16 and a second connecting hole 17, and the steel pipe 6 extends through the first connecting hole 16 and the second connecting hole 17 to the outside of the connector 9.

[0040] Preferably, the top of the connector 9 is provided with a retaining wall 18, and the support plate 8 is located inside the retaining wall 18.

[0041] In this invention, the limiting plate is first rotated to misalign the protrusions and grooves, and then the main beam and secondary beam are installed sequentially. At this point, the load is transferred to the limiting plate, then through the protrusions to the support rods, and finally to the frame structure. When the upper concrete reaches the conditions for early removal, the protrusions on the limiting plate are struck with a hammer, or the limiting plate is rotated using other methods, causing the grooves on the limiting plate and the protrusions on the support rods to couple. Under gravity, the limiting plate slides downwards along the support rods, thereby causing the upper connectors and main beams to slide downwards together. At this point, the main beams and secondary beams detach from the formwork, while the support columns still support the formwork, thus achieving the purpose of early removal.

[0046] Example 5 This embodiment further defines the embodiments 1, 2, 3 and 4, with a first main beam 2 and a secondary beam 3 provided between the two sets of support frames 1, and the first main beam 2 located at both ends of the support frame 1.

[0047] Preferably, the support frame 1 includes a connector 9, which is sleeved on the outside of the steel pipe 6.

[0048] Preferably, the connector 9 is located above the protrusion 7, and the limiting plate 10 is located below the connector 9. The connector is a component used to connect the main beam in four directions. It has a cubic structure and two connecting holes. The inner diameter of the upper connecting hole is slightly larger than the outer diameter of the support rod, and the lower connecting hole is slightly larger than the outer diameter of the support rod plus the thickness of the two protrusions.

[0049] The two connecting holes are connected by a support wall, which can transfer the upper load to the lower limiting plate. The height of the support wall is the lowering height of the main beam during early dismantling.

[0050] During use, the connector is set on the support rod through the connection hole. A second main beam 4 is set between the two support frames 1. The two ends of the second main beam 4 are welded to the connector 9. The main beam is used to directly support the template and is usually made of aluminum alloy. Its cross-section is a hollow rectangle. In addition, a support plate is set in the middle of its cross-section. The support plate runs through the middle of the main beam and is mainly used to place the secondary beam. The connector 9 includes a first connection hole 16 and a second connection hole 17.

A enclosure 18 is set on the top of the connector 9, and the support plate 8 is located inside the enclosure 18.

[0051] In this invention, the limiting plate is first rotated to misalign the protrusions and grooves, and then the main beam and secondary beam are installed sequentially. At this point, the load is transferred to the limiting plate, then through the protrusions to the support rods, and finally to the frame structure. When the upper concrete reaches the conditions for early removal, the protrusions on the limiting plate are struck with a hammer, or the limiting plate is rotated using other methods, causing the grooves on the limiting plate and the protrusions on the support rods to couple. Under gravity, the limiting plate slides downwards along the support rods, thereby causing the upper connectors and main beams to slide downwards together. At this point, the main beams and secondary beams detach from the formwork, while the support columns still support the formwork, thus achieving the purpose of early removal.

[0052] This utility model discloses a support rod composed of a support plate, a steel pipe, and protruding ribs. The support plate is located at the end of the steel pipe and serves to support the template. The protruding ribs support the limiting disc and are located on the outer wall of the steel pipe, with at least two ribs. The limiting disc is the core component of the early disassembly structure; it is a circular ring structure with an inner diameter slightly larger than the outer diameter of the support rod for easy rotation. It has protrusions and grooves. The protrusions facilitate the operator's rotation of the limiting disc, typically achieved by striking it with a hammer. There are at least two of these protrusions. The grooves need to be coupled with the protruding ribs of the support rod, and their size and number correspond to the protruding ribs on the support rod. To better constrain the protruding ribs and facilitate easier rotation of the limiting disc, wedge-shaped grooves or wedge-shaped protrusions can be provided on the limiting disc.

[0053] The width of the wedge groove or wedge block should be slightly larger than the width of the support column protrusion to fully accommodate the protrusion and prevent stress concentration.

[0054] The wedge groove or wedge block consists of two parts: a horizontal part and an inclined part. When installing the early removal structure, the protruding edge needs to be aligned with the horizontal part of the wedge groove or wedge block.

[0055] When early disassembly is required, tap the limiting plate to make it rotate. At this time, the inclined part of the wedge groove or wedge block and the convex edge come into contact. Since the inclined part is a slope, the height of the limiting plate gradually decreases, and the pressure on the limiting plate gradually decreases, thus making it easier to complete the disassembly.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
