Abstract

The invention relates to a pre-supporting and post-mounting shaping early-dismantling form system. The pre-supporting and post-mounting shaping early-dismantling form system comprises a supporting system and a form system; the supporting system comprises a supporting frame body, a jacking, a supporting beam and a beam bottom supporting device; the supporting frame body is an integral bracket formed by erecting scaffold steel pipes; the jacking comprises an early-dismantling jacking and a common jacking; the supporting beam comprises a plate bottom supporting beam and a beam bottom supporting beam; the form system comprises a floor form, a rear dismantling base plate, beam side forms and a beam bottom form, the floor form is located on the plate bottom supporting beam; and the beam bottom form is located on the upper side of the beam bottom supporting device, and the beam side forms are located on the two sides of the beam bottom form correspondingly. According to the pre-supporting andpost-mounting shaping early-dismantling form system, the strength and rigidity requirements of the shaping form are greatly reduced, so that the weight, the manufacturing cost and the processing difficulty of the shaping form are reduced, the problem that the shaping form is difficult to adapt to an integral supporting system is effectively solved, and the pre-supporting and post-mounting shapingearly-dismantling form system has wider application range.

Description

technical field

[0001] The invention belongs to the technical field of construction engineering, and relates to an early demolition formwork system, in particular to an early demolition formwork system and a construction method thereof. Background technique

[0002] Early demolition formwork is a formwork support device and method adopted to realize early demolition of floor formwork. Its working principle is "remove the slab without dismantling the column". As long as the concrete strength reaches 50% of the design strength, the floor formwork and Part of the supporting uprights, while most of the supporting uprights and adjustable supports remain in the supporting state. When the strength of the concrete meets the design requirements, all the supporting uprights are removed. According to the construction sequence, the early demolition formwork can be divided into the method of supporting first and then installing and the method of installing first and then supporting, and ...

Embodiment Construction

[0050] Such as Figure 1 to Figure 16 As shown, the present invention is a formwork system that is supported first, then installed, fixed, and early dismantled, including a support system and a formwork system.

[0051] The support system of the present invention includes a support frame body, a jacking, a support beam and a support device 4 at the bottom of the beam; An integral support erected by scaffolding steel pipes of this type not only has the capacity to carry formwork, concrete and construction loads, but also has the stability to ensure the stability of the entire formwork system. In this embodiment, the support frame body includes plate The support pole 10 is removed at the bottom, the support pole 12 is removed early at the bottom of the board, the support pole 1 is removed at the bottom of the beam, the support pole 14 is removed early at the bottom of the beam, and the connecting cross bar 13; and the common jacking bracket 11, the early demolition jacking brac...
