A displacement-compensating support fitting

Abstract

This invention provides a displacement-compensating support accessory, including a horizontal support tray mounted on the upper end of a vertical screw. Adjustable-width clamps are symmetrically arranged on both sides of the horizontal support tray. A horizontal screw is provided on the top surface. A longitudinal slide rail groove is provided in the middle of the adjustable-width clamp, and the lower end is bent into an L-shape towards the middle of the horizontal support tray. The two ends of the horizontal screw are slidably placed in the slide rail grooves on both sides, and their relative positions with the slide rail grooves are locked by fastening nuts. An adjustable support column is threaded onto the horizontal screw. This invention, through a modular design of "clamp fixing + horizontal bidirectional adjustment + vertical support," efficiently compensates for construction deviations without changing the original disc-lock frame layout, ensuring that the support point is always aligned with the early dismantling head.

Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a support bracket for compensating for displacement. Background Technology

[0002] In the construction industry, a key technical problem exists in existing formwork support systems using disc-lock scaffolding to support early-stripping heads of aluminum alloy formwork: when there is a construction deviation between the design point of the early-stripping head and the standard spacing of the lower disc-lock uprights, the top support in the traditional support system cannot be adjusted horizontally, resulting in inaccurate alignment. Common solutions include manually prying the top support (which poses significant safety hazards and is ineffective) or dismantling and rebuilding parts of the scaffolding. These methods are not only inefficient but also significantly increase labor and material costs, severely impacting project progress. The main drawbacks can be summarized as follows: 1. Poor flexibility and low tolerance for error: Traditional modular scaffolding uprights are arranged according to a fixed module, while the early dismantling head of aluminum alloy formwork often deviates from the center of the uprights due to structural design requirements. Existing top supports lack effective horizontal adjustment capabilities and cannot compensate for such construction deviations, resulting in insufficient adaptability of the support system to design changes.

[0003] Second, low construction efficiency and high cost: When positional deviations occur, a large amount of manpower is often required for temporary adjustments or even partial dismantling and alteration of the scaffolding, which is cumbersome and time-consuming. Manual prying can easily lead to component damage and safety risks, while dismantling and alteration work further increases material waste and repetitive labor, significantly driving up the overall construction cost.

[0004] Third, strong specialization and insufficient versatility: Some special adjustment components or customized solutions currently available on the market are usually complex in structure, inconvenient to install, and have poor compatibility with conventional disc buckle frame components, making it difficult to apply them on a large scale in existing projects, which restricts their promotion value. Summary of the Invention

[0005] To address the aforementioned issues, this invention discloses a displacement-compensating support top bracket. Through a modular design of "clamp fixing + horizontal bidirectional adjustment + vertical support," it efficiently compensates for construction deviations without altering the original disc buckle frame layout, ensuring that the support point is always aligned with the early dismantling head.

[0006] The specific plan is as follows: A displacement-compensating support fitting includes a top support horizontal tray mounted on the upper end of a vertical screw. The top support horizontal tray has adjustable width clamps symmetrically arranged on both sides, and a transverse screw on the top surface. The adjustable width clamp has a slide rail groove in the middle along the longitudinal direction, and the lower end is bent into an L-shape towards the middle of the top support horizontal tray. The two ends of the transverse screw are slidably placed in the slide rail grooves on both sides, and their relative positions with the slide rail grooves are locked by fastening nuts. An adjustable support column is threaded onto the transverse screw.

[0007] Furthermore, a top support vertical screw buckle is fitted onto the vertical screw and is threadedly connected to it.

[0008] Furthermore, the transverse screw is perpendicular to the slide rail groove.

[0009] The beneficial effects of this invention are as follows: A support bracket accessory that can be clamped and fixed to a top support is designed. This accessory integrates a bidirectional orthogonally arranged horizontal adjustment mechanism, specifically mutually perpendicular slide rails and screws. The column is positioned by bidirectional sliding and locking in the X and Y directions within the horizontal plane, thus adjusting the position of the upper support point. The top of the column can precisely connect with the early-release head of the aluminum alloy template. Specific advantages are as follows: 1. It can be installed on the existing support brackets on the construction site.

[0010] 2. It can realize the docking connection between the disc buckle support frame and the metal template or the standardized template.

[0011] 3. It can compensate for the deviation between the construction support frame and the customized template. Attached Figure Description

[0015] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0016] As shown in the figure, this invention provides a displacement-compensating support top bracket accessory, including a top bracket horizontal tray 5 installed on the upper end of a vertical screw 7. Adjustable width clamps 3 are symmetrically arranged on both sides of the top bracket horizontal tray 5. A transverse screw 2 is provided on the top surface. A slide rail groove 8 is longitudinally arranged in the middle of the adjustable width clamp 3, and the lower end is bent into an L-shape towards the middle of the top bracket horizontal tray 5. The two ends of the transverse screw 2 are slidably placed in the slide rail grooves 8 on both sides, and their relative positions with the slide rail grooves 8 are locked by fastening nuts 4. An adjustable support column 1 is threadedly connected to the transverse screw 2. A top bracket vertical screw buckle 6 is fitted onto the vertical screw 7 and threadedly connected to it. The transverse screw 2 is perpendicular to the slide rail groove 8.

[0017] Construction Principle: The adjustable support column 1 is connected to the early-release head of the aluminum alloy formwork to bear the vertical load of the metal formwork. The horizontal screw 2 passes through the adjustable support column 1 and is adjusted and positioned using a screw and nut structure. The horizontal screw 2 and the fastening nut 4 are adjusted for tightness using the screw and nut structure and their positions are adjusted in the slide rail groove 8, achieving bidirectional adjustment of the adjustable support column 1. The adjustable width clamp 3 is clamped onto the top support horizontal tray 5 by the horizontal screw 2 and the fastening nut 4, and the vertical force of the adjustable support column 1 presses on the top support horizontal tray 5. The force is transmitted to the vertical support frame through the top support horizontal tray 5, the top support vertical screw buckle 6, and the vertical screw 7.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
