Description

A tool platform suitable for the positioning of cast-in-place pile reinforcement cages and conduits

technical field

The invention belongs to the field of civil engineering construction, and in particular relates to a device for lengthening reinforced cages of cast-in-place piles and pouring concrete.

Background technique

In the prior art, during the construction of cast-in-situ piles, the steel cage is often positioned by inserting section steel to support the top of the steel casing during the lengthening process of the steel cage. When inserting and pulling out the section steel, the physical strength of the operator is greatly consumed, and it is also There are certain safety risks; with the development of civil engineering technology, there are more and more large-diameter deep and long piles, which makes the reinforcement cage of the pile body heavier and more segmented, and the gap between the vertical main bars is also smaller. The smaller the size, the larger the section steel cannot penetrate the gap between the vertical main bars, and the strength of the smaller section steel cannot meet the force requirements. At the same time, the increase in the number of sections will double the work intensity of the operator. In order to solve this kind of problem, the process of positioning the steel cage by adopting the piggyback method has begun to be applied, but the piggyback plate, the key structure of the piggyback process, is still supported on the top of the steel casing, and there is a risk of the steel casing sinking suddenly. The operator's operating surface that the tray can provide is very small, and there are hidden dangers in construction safety. When pouring concrete, the conduit support platform is often hoisted and placed directly on the top of the steel casing, which poses a risk of overturning and poses a great safety hazard.

Contents of the invention

The purpose of the present invention is: the present invention creates a positioning technology based on the positioning technology in the lengthening process of the cast-in-place pile reinforcement cage and the positioning technology when the conduit is lengthened and lifted during the concrete pouring process, and proposes a tool suitable for positioning the cast-in-place pile reinforcement cage and conduit The platform can meet the needs of the above two process links, and can well solve the problem of fast and safe positioning of pile foundation reinforcement cages with super long, overweight and small vertical main reinforcement gaps. It can also realize the rapid positioning and safety of the concrete pouring conduit positioning operation platform At the same time, it also avoids the risk of sudden sinking of the steel casing caused by the steel cage being directly supported on the top of a single steel casing, and also avoids the risk of slipping and overturning when the catheter positioning platform is placed directly on the top of the steel casing.

In this scheme, the angle steel and the frame beam form a slot to limit the sliding and overturning of the conduit limiting platform, and also allow the conduit platform to slide in the slot during the process conversion process.

Alternatively, each movable supporting mechanism is evenly distributed on the circumference of the orifice, and its orientation points to the center of the orifice. In this scheme, the force of the movable supporting mechanism is balanced, stable and reliable.

The above-mentioned main scheme of the present invention and its further options can be freely combined to form multiple schemes, all of which are applicable and claimed in the present invention; can also be combined freely. After understanding the solution of the present invention, those skilled in the art can understand that there are various combinations based on the prior art and common knowledge, all of which are technical solutions to be protected by the present invention, and are not exhaustive here.

Compared with the prior art, the platform device of the present application has three characteristics:

1. The commonly used method for temporary positioning of existing reinforcement cage extensions is to directly insert profiled steel from the vertical main reinforcement gap, and support the profiled steel on the top of the protective tube. Operators often stand on the supporting profiled steel to carry out the operation of reinforcing bar extension. There are risks to personnel safety and quality caused by the sudden sinking of the casing. At the same time, during the construction of large-diameter and super-long pile foundations, the small-sized section steel cannot meet the force requirements when supporting the self-weight of the reinforcement cage, and the large-scale section steel cannot be removed from the pile. The reinforcement cage runs through the middle of the vertical main reinforcement. The tool platform of this application is directly supported on the outer load-bearing structure of the casing through the frame beam, which avoids the risk of sudden sinking caused by the self-weight of the reinforcement cage concentrated on the casing. At the same time, the reinforcement cage is temporarily positioned through the bolts around the platform. The light bolt It can be easily plugged and unplugged with only one operator, and the operation efficiency is greatly improved;

2. When pouring pile foundation concrete, the conventional method is to directly support the conduit positioning platform on the top opening of the casing. In this way, there is a risk of sudden subsidence caused by all the loads acting on the casing, and there is also the possibility that the platform will slip and overturn from the casing opening risks of. In the tool platform of this application, the catheter positioning platform is connected to the frame beam through the angle steel of the limiting device, and the angle steel and the frame beam form a slot to limit the sliding and overturning of the catheter limiting platform, and to make the catheter platform during the process conversion process slide in the card slot;

3. In the construction of cast-in-situ piles, the measures and structures used by the two tools of steel cage lengthening and concrete pouring conduit positioning are often independent. Each process change must be lifted from the measure structure of the previous process and then hoisted in place. The measure structure of the process is inefficient. The tool-type platform of this application integrates the platforms of these two processes. In the process of steel cage lengthening, it is only necessary to slide the catheter positioning platform to the end without hindering the operation of this process. When entering the next process, only need to move the The catheter positioning platform slides to the opening of the casing, which is efficient and quick.

Beneficial effects of the present invention:

1. Safe and reliable. The safety risk caused by the sudden sinking of the steel casing is avoided;

2. Efficient and quick. A safe and reliable working platform is provided for the operators, and the measures and components required for the operation of the required personnel are simple and light, which greatly improves the working efficiency;

3. It reduces on-site operations and has high economy. The measures and structures required for the lowering of the reinforcement cage and the pouring of the concrete are integrated on one platform, which reduces the hoisting operation during the conversion of the process and saves energy and equipment costs.
