Problems solved by technology

However, when the height of the formwork exceeds 20m in this method, not only the amount of scaffolding steel pipes and fasteners is huge, but also the labor cost for erection is high, and the force transmission of the steel pipe formwork frame with super-high floor fasteners is complicated, and there are many safety hazards

Embodiment Construction

[0038] As shown in Figures 1-3, a cable-stayed steel truss high formwork structure system according to the present invention includes a main load-bearing steel truss 1, a connecting steel support 2, a truss cable-stayed hanging bar 3, and a beam 4 And steel pipe scaffold formwork support 5, four steel trusses 1 are set on the structure of the completed building under the high-altitude and long-span reinforced concrete floor to be poured in the form of two-end support, and the steel trusses 1 of each group are connected by setting steel supports 2 To increase the plane stability of the steel truss, the four truss cable-stayed hanging bars 3 are symmetrically suspended between the steel truss 1 and the main structure of the completed building on both sides; The formwork support 5 is built on the beam 4, and the tall atrium floor 6 is poured on the basis of the steel pipe scaffold formwork support 5. The steel truss 1 can be a finished Bailey frame or a military truss beam, or a ...

Abstract

This is a cable stayed steel truss module structure and its construction method. At least two steel trusses are installed to support a high building to be grouted with connecting steel held in between. At least four truss cables are stayed between the building and the steel truss. Beam is installed on the top of the truss with falsework module fixed to the beam.

Description

1. Technical field [0001] The invention relates to a building construction formwork structure system, specifically a cable-stayed steel truss high formwork structure system, and also relates to a construction method of the cable-stayed steel truss high formwork structure system. 2. Background technology [0002] In the construction of cast-in-place concrete structures such as high-rise building conjoined structures and public building shared spaces, the overall collapse of tall and large formworks has caused serious accidents that caused many casualties. The Ministry of Construction will also Construction safety is listed as a key management content. For the formwork of the cast-in-place concrete floor construction of the high hall, the conventional construction method is to use the fastener-type steel pipe scaffolding to support the formwork from the ground full of bent frames. However, when the formwork height of this method exceeds 20m, not only the amount of scaffolding...
