Whole roof system synchronous jacking method

Abstract

The invention discloses a whole roof system synchronous jacking method. A counterforce support is arranged on existing vertical components, a hydraulic jack is arranged between the counterforce support and a roof system frame column, the existing vertical components are cut off, meanwhile a limiting device and a movable two-way pull rod are arranged, whole synchronous jacking is carried out through a PLC synchronous lifting control system, and after jacking is conducted in place, the vertical components are supported by temporary steel cushion blocks; and height addition is conducted on the vertical components, after concrete of a height addition part reaches the designed strength, the temporary support is removed, and therefore the purpose that the height of a building is increased is achieved.

Description

technical field [0001] The invention relates to the technical field of municipal construction, more specifically, it relates to a synchronous jacking method for an integral roof. Background technique [0002] At present, there are many factory buildings or commercial buildings that are not high enough and need to be heightened and reconstructed. However, the method of raising the roof of factory buildings in the prior art is generally the method of removing the roof of the original building, and then re-roofing after heightening. This method not only has the disadvantages of costing a lot of money and long construction period, but also makes it difficult to carry out construction hoisting due to the installation of many equipment and ground structures in the original factory building.

[0002] At present, there are many factory buildings or commercial buildings that are not high enough and need to be heightened and reconstructed. However, the method of raising the roof of factory buildings in the prior art is generally the method of removing the roof of the original building, and then re-roofing after heightening. This method not only has the disadvantages of costing a lot of money and long construction period, but also makes it difficult to carry out construction hoisting due to the installation of many equipment and ground structures in the original factory building. The technical scheme of overall jacking and heightening of the top surface. In this technical scheme of overall jacking, the jacking support member must be built in the factory building first, and then the jack is placed on the support member to lift the roof of the house. Then connect the pillars on the supporting columns of the original factory building, then lower the roof of the house, and finally remove the jacking support components built in the factory building. The main problems of this overall jacking scheme in the prior art are: 1. 1. When erecting the jacking support components, the site in the factory building will be occupied, which cannot be carried out for some workshops full of equipment; 2. When building the jacking support components, many materials are used, which is labor-intensive and time-consuming; 3. The construction process is complex, difficult, poor in safety and long in construction period

As a result, the existing space height and size of some building floors cannot meet the new functional requirements for commercial use, such as shopping malls planning theaters or exhibition halls, etc., and this part of the building floors will face the threat of demolition and reconstruction, which is only for buildings with good structural functions. If the space height is not satisfied, demolition and reconstruction will cause huge waste of resources and serious pollution of the surrounding environment, which is not a more effective method
