Description

Technical Field

[0001] This invention relates to the field of concrete placing boom support technology for floor slab concrete pouring, specifically to a construction method for a concrete placing boom with reinforcing bar support feet. Background Technology

[0002] In the construction of concrete slabs for building floors, the concrete placing boom is the core pumping and placing equipment, and its support method directly affects the construction quality and safety. In traditional construction, the placing boom's supports are usually placed directly on the floor slab reinforcement, or simply supported by wooden beams and formwork. This traditional approach has the following drawbacks: 1. The continuous vibration generated by the placing boom's pumping and rotating operation can easily cause displacement and deformation of the floor slab reinforcement, affecting the structural performance of the floor slab; 2. Vibration can easily squeeze and damage embedded electrical and plumbing pipelines, leading to rework and repairs, increasing construction costs and time; 3. The wooden beams and formwork supports lack sufficient rigidity and stability, easily slipping and tilting, posing safety hazards; 4. The wooden beams and formwork have a low turnover rate and high wear and tear, generating a large amount of construction waste, which does not meet the requirements of green construction. Currently, there is a lack of a tool-based, adjustable, reusable, non-damaging, and reliably stable support device for placing booms to meet the needs of construction safety, quality, efficiency, and energy conservation and environmental protection. Summary of the Invention

After placing it stably, tighten the connecting nuts to secure it. Commissioning and trial operation: No-load trial operation to check the stability of the support and the normal operation of the equipment; Concrete pouring: Pour evenly in the specified order, avoiding collisions between the reinforcing bar supports and the reinforcing bars; reposition and reinstall the reinforcing bar supports when moving the concrete placing boom; Demolition and Cleaning Maintenance: After pouring, promptly remove the reinforcing bar supports and compact the concrete at the reinforcing bar supports with secondary vibration; clean the equipment, inspect the threads, spray rust inhibitor, wrap and protect it for reuse.

[0005] Furthermore, the outrigger pad is a square steel plate with holes for installing adjusting screws at the four corners and a hole for installing connecting screws in the middle.

[0006] Furthermore, the adjusting screw is a stainless steel foot cup with a rubber bottom.

[0010] Furthermore, the overall reinforcement arrangement passes through the gaps in the floor slab reinforcement and is directly supported on the bottom formwork, transmitting force from the bottom formwork to the formwork support frame, forming an overall force-bearing system.

[0011] Compared with the prior art, the present invention has the following beneficial effects: Reliable quality: The through-beam support does not press on the reinforcing bars or touch the pipelines, eliminating the deformation of the reinforcing bars and damage to the embedded pipes caused by vibration, thus improving the quality of the floor slab formation; Safe and stable: The overall force transmission is clear, the rigidity is sufficient, it is adjustable and prevents loosening, avoiding settlement, tilting and instability; Highly efficient and convenient: Tool-based installation, adjustment, and dismantling make operation simple and significantly shorten setup time; Economical and environmentally friendly: It can be reused more than 20 times, significantly reducing the consumption of timber and formwork, lowering costs and construction waste, and conforming to green construction.
