Example Embodiment

[0054] Example:

[0055] In this embodiment, the temporary support conversion devices are a pair of symmetrical ones, which are respectively installed on the two phase sides of the structural column 7 of this floor, so that the vertical load can be converted reasonably, and the safety of the reinforced concrete structure can be ensured during the reverse demolition process.

[0056] The support plate 2 is the part near the structural column 7 under the structural beam 8 of this floor. A pair of L-shaped steel 5 has a reserved L-shaped steel bolt hole 6 on the corner side, and the L-shaped steel 5 can be fixed on the structural beam 8 by high-strength bolts. On the one hand, it can disperse the concrete pressure generated by the concentrated force on the concrete, and on the other hand, it can also make the force of the vertical load act on the structural beam 8 more evenly. Spread the load with the support plate 2.

[0057] The supporting plate 2 also includes the supporting ...

Abstract

The invention discloses a reinforced concrete structure reverse dismounting temporary supporting conversion device and an operation method thereof, and belongs to the technical field of building reverse dismounting. The device comprises jacks, bearing plates, short post connecting elements, supporting short posts and L-shaped steel, wherein the jacks, the bearing plates, the support short posts and the L-shaped steels form temporary support structures; a pair of temporary support structures are arranged at the two sides of a structure post; the vertical bearing force transmitted by the structure post is replaced; the bearing capability of the reinforced concrete structure post and a structural beam is sufficiently used, so that the vertical load is transmitted onto the temporary support structures through the structural beam; the bearing force is reasonably converted; and the safety in the reverse dismounting process is ensured. The support short posts are mainly used for bearing the vertical load; the support short posts are detachably spliced and can be repeatedly used; and a part of dismounting cost is reduced. The bearing plates are used for uniformly converting the vertical support force and ensuring the vertical support effects. Through the vertical direct conversion of the force, the stress is direct and safe.

Description

technical field [0001] The invention belongs to the technical field of reverse demolition of buildings, and in particular relates to a temporary support conversion device for reverse demolition of reinforced concrete structures and an operating method thereof. Background technique [0002] At present, a large proportion of the demolition of urban buildings is reinforced concrete structures. Traditionally, mechanical demolition and blasting demolition of reinforced concrete are mainly used, supplemented by manual demolition. The demolition of high-rise buildings is still dominated by controlled blasting. Demolition and mechanical demolition are equally important. These traditional demolition methods are more suitable for suburban or more remote houses. The impact on the surrounding environment must be taken into account when demolishing buildings in towns or urban areas with low building density, including the noise generated, the dust generated, whether construction can be ...
