Problems solved by technology

[0007] Aiming at the overall demolition and reconstruction of large-space steel roofs, the method of first removing the old roof and then building a new one has the problems of time-consuming and expensive, and the internal structure of the building may be damaged in bad weather during construction. The present invention Provides a new and old steel roof overall lifting replacement construction method, the new steel roof adopts overall assembly and overall lifting, and provides an operation platform for the removal of the old steel roof, with convenient operation, fast construction speed, and strong weather adaptability Etc

Embodiment 1

[0049] to combine Figure 1 to Figure 10 As shown, the construction method for the overall upgrading and replacement of new and old steel roofs provided in this embodiment includes the following steps:

[0050] Step one, such as figure 1 As shown, an assembled tire frame 3 is set directly under the old steel roof 1 that needs to be removed, and the new steel roof 4 is integrally assembled on the assembled tire frame 3; after the overall assembly of the new steel roof 4 is completed, the new steel roof 4 and lay isolation protection device 6 on it.

[0051] For large-space steel structure buildings, the old steel roof 1 provides support through the peripheral permanent structure 2 of the building, and the peripheral permanent structure 2 can be a structural column. The old steel roof 1 has the characteristics of large span and heavy weight.

[0052] In the overall assembly of the new steel roof 4, a crane 5 is used for auxiliary construction. The orthographic projection area...

Embodiment 2

[0080] The difference between this embodiment and the first embodiment is that the construction sequence of step 6 to step 8 in the first embodiment is adjusted. The specific adjustments are:

[0081] Step 6. Cut and disassemble the old steel roof on the operating platform provided by the new steel roof, and use a crane to remove the cut old steel roof components to complete the demolition work of the old steel roof;

[0082] Step 7. Remove the temporary fixation around the new steel roof, and the computer control system controls the lifting power mechanism to lift the new steel roof to the design level;

[0083] Step 8: Complete the fixed connection between the new steel roof and the peripheral permanent structure.

[0084] It can be seen that step 6 of this embodiment is based on step 5, first remove the old steel roof on the new steel roof, and then raise the new steel roof to the design elevation separately, and realize the new steel roof The roof is fixed.

[0085] Fur...

Abstract

The invention discloses a construction method for overall lifting and replacement of new and old steel roofs, which mainly includes the following steps: performing overall assembly of new steel roofs on the assembled tire frame directly below the old steel roof; setting an overall lifting system; using the lifting system Lift the new steel roof to the bottom of the old steel roof; set up several steel supports; remove the connection between the old steel roof and the peripheral permanent structure; lift the new steel roof and the old steel roof together to make the new steel roof rise to the design level Elevation; fix the new steel roof; cut and disassemble the old steel roof on the operating platform provided by the new steel roof. The construction method described is less affected by weather factors, requires less cranes, and the internal building structure can be fully protected during construction; moreover, the new steel roof provides a safe operating platform for the removal of the old steel roof, which solves the problem of high-altitude problems. The safety of the operation reduces the difficulty of dismantling the old steel roof, allows multiple working faces to be constructed at the same time, and effectively improves the construction efficiency.

Description

technical field [0001] The invention relates to a construction method for overall lifting and replacement of old and new steel roofs, and belongs to the technical field of building steel structure construction. Background technique [0002] With the continuous development of the city, more and more attention has been paid to the renovation and renewal of existing buildings. Especially for steel structure buildings, it is easy to cause problems such as corrosion of steel components. With the continuous increase of the service life of steel structure buildings, these problems have become increasingly prominent, and will seriously affect the safety of the entire structure. For this reason, in the renovation and renewal of old building steel structures, it is often necessary to carry out safety inspection and evaluation on the existing steel structures, and to carry out corresponding reinforcement or replacement. For serious problems, it even needs to be rebuilt after the overa...
