Description

A wooden formwork early demolition independent support reinforcement system

technical field

The utility model relates to the field of construction tools, in particular to an independent support and reinforcement system for early demolition of wooden formwork.

Background technique

The usual method of wood formwork support system: use fastener-type steel pipe scaffolding, wheel-buckle scaffolding or coil-buckle scaffolding as the formwork support frame, and the time for formwork removal should be determined according to the reported value of the concrete compressive strength. Usually the span of beams and slabs is ≤8m, and the removal of the formwork needs to be carried out after the concrete strength reaches 75% of the design value. After the concrete pouring is completed, the corresponding formwork removal strength can be reached after 7 days of curing; the span of beams and slabs is greater than 8m, and the removal of the formwork needs to be done after the concrete The strength can only be carried out when the strength reaches 100% of the design value. After the concrete pouring is completed, it usually takes 30 days or more to maintain the corresponding formwork removal strength.

The objective shortcoming of prior art:

(1) The form removal time is too long, which is not conducive to the turnover of the formwork, especially in the construction process of the basement structure. The turnover rate is extremely low, resulting in serious waste of formwork and excessive investment in formwork materials.

(2) The form removal time is too long, resulting in a serious backlog of formwork, which cannot be removed in time and used in other construction areas, making secondary handling very difficult, which not only increases labor costs, but also increases the cost of civilized construction.

1. The early dismantling of the wooden formwork and the independent support rods are self-made rods, which are easy to install, and the height of the rods can be adjusted through adjustable rods, which are suitable for different storey height requirements, and have strong versatility and practicability.

2. On the basis of the conventional formwork frame, the independent support system for the early demolition of the wooden formwork is added, which can realize the demolition work in areas other than the independent support system for the early demolition of the wooden formwork in advance, greatly improving the turnover rate of the formwork and greatly reducing the cost of the formwork. Reduce the loss rate and reduce the investment in civilized construction.

3. By adding an independent support and reinforcement system for early demolition of wooden formwork, an independent force-bearing support member can be formed, the original design span of beams and slabs can be reduced and controlled within 2 meters, and the floor formwork can be removed in advance and used in turnover.

As shown in the figure: 1. Formwork strip 2, double square tube 3, independent support 4, adjustable rod 5, support plate 6, U-shaped support plate 7, seamless steel pipe 71, upper seamless steel pipe 72, lower end Seamless steel pipe 8, positive nut 9, reverse nut 10, screw mandrel 11, rotating rod.

Detailed ways

Below in conjunction with accompanying drawing 1-3 the utility model is described further.

An independent support and reinforcement system for early demolition of wooden formwork, comprising an independent support 3, a formwork bar 1 arranged above the independent support 3, a double square pipe 2 is arranged on the independent support 3, and the formwork strip 1 is arranged on the double square pipe 2 Specifically, the independent support 3 includes a seamless steel pipe 7 , an adjustable rod 4 , and a support pad 5 .

The seamless steel pipe 7 includes two groups, the seamless steel pipe 7 includes an upper seamless steel pipe 71 and a lower seamless steel pipe 72, and the adjustable rod 4 is arranged between the upper seamless steel pipe 71 and the lower seamless steel pipe 72, specifically Yes, the bottom of the seamless steel pipe 71 at the upper end is provided with a positive nut 8. Anti-nut 9 is established on the bottom seamless steel pipe 72 tops. The adjustable rod 4 includes a screw 10 and a rotating rod 11 , and the rotating rod 11 is sleeved on the screw 10 .
