Abstract

FIELD: construction engineering. SUBSTANCE: this relates mainly to reconstruction of long buildings with adding more storeys. Reconstruction is effected successively by diving building into sections and doing one section after another. According to method, made in longitudinal walls of building are holes, inserted into these holes are lateral members with thread on their ends, and temporary supports are installed outside building with fixing them in window openings of top storey and fastening with lateral members by means of nuts. Supports are installed simultaneously on two adjacent sections of building, and guide members are mounted over supports. Then, tent is built on guide members above section to be reconstructed. Under protection of tent, old structures are dismantled and new structures are built. After that, tent is moved to following section and procedure is repeated. Tent and all supports are dismantled on completion of reconstruction operations. EFFECT: high efficiency. 3 dwg

Description

 The invention relates to the field of construction and can be used in the reconstruction of long houses with an increase in the number of storeys without resettlement of residents.

 There is a method of conducting construction work, in the process of which protection from weathering is required, for example, reinforcing and concrete work in greenhouses (tents) during the construction of reinforced concrete exhaust pipes [1] Such greenhouses are mounted on a self-hoisting crane that allows scaffolding, greenhouse and formwork to be moved as pipe construction.

 Closest to the proposed method is a method of reconstruction of a blast furnace workshop [2] This method allows reconstruction of the main production facilities under the protection of a tent mounted on temporary supports installed next to the existing columns of the reconstructed building. The disadvantages of this method include the need to use heavy crane equipment, the need for additional space outside the reconstructed workshop, and the fact that when moving to the reconstruction of the next section of the workshop, the tent must be dismantled and then reassembled.

 The technical task is to simplify the method and reduce the time required for reconstruction of extended buildings due to the possibility of using the erected tent in stages and on separate grips of the building without dismantling it.

 The problem is solved in such a way that in the method of building reconstruction, including erecting a tent over the reconstructed building grab with its support on temporary supports installed along the longitudinal walls, disassembling old structures, erecting new building structures, dismantling the tent and temporary supports, according to the invention, previously the longitudinal walls of the building above the ceiling of the last floor make holes and stretch the bonds in them, establish temporary supports outside the building, resting on the wall in the window rails of the last floor and securing them with ties, after which on the supports along the walls of the building at a distance equal to the sum of the lengths of the reconstructed building grab and the subsequent grab to be reconstructed, the rails are mounted, the tent is erected over the reconstructed building grab, resting it on the rails, then the old ones are disassembled structures and the construction of new ones, after that the tent is moved along the guides to the next grab to be reconstructed, and the temporary supports and the guides are rearranged to the following capturing the building, and dismantling the tent is carried out after the reconstruction of the building along the entire length.

 The proposed method differs from the known one in that previously holes are made in the longitudinal walls of the building above the ceiling of the last floor and the reinforcement steel ties are drawn into them, there is a thread at the ends of the ties. Then, temporary supports are installed outside the building, resting on a wall in the window openings of the last floor and securing them with ties using nuts, which allows for reconstruction of the roof, wall extension and other construction work on the building superstructure without resettling residents. In addition, the proposed method is characterized in that the supports are fixed with diagonal elements, after which the rails are mounted on supports along the walls of the building at a distance equal to the sum of the lengths of the reconstructed building grab and the subsequent grapple to be reconstructed, based on which the tent is erected over the reconstructed building grab . Then, under the protection of the tent, old structures are dismantled and new ones are erected, thus, reconstruction works are carried out under favorable conditions under the roof, and the existing building is protected from adverse atmospheric influences. The tent after that, without disassembling, is moved along the guides to the subsequent grapple to be reconstructed. Temporary supports and guides from the gripper, on which reconstruction work is completed, are rearranged to the next eahvatki of the building. This method eliminates the cost of disassembling and the subsequent erection of the tent over the next grab. Dismantling of the tent and all temporary supports is carried out after the reconstruction of the building along the entire length.

 In FIG. 1 shows a reconstructed building during the superstructure; FIG. 2 view A A of FIG. 1, in FIG. 3 node A of FIG. 2 example of a constructive solution of temporary support.

 In FIG. Figure 1 shows how reconstruction was organized by seizures with an increase in the number of storeys of an extended house: work on capture "a" was started and completed, work is underway on the reconstructed capture "b".

 The method is carried out in the following sequence. For the reconstruction of an extended building 1 with an attic superstructure 2, the building is divided into technological grips “a”, “b”, “c”, etc. the size of which is determined by the convenience of work. Expeditions are 200-300 sq. M. m, which corresponds to one entrance (one section) of a residential building.

 In the longitudinal walls of the building above the ceiling of the last floor, holes 3 are made and ties 4 are drawn in them. Then, temporary supports 5 are installed, resting on the wall in the window openings 6 and securing them with nuts by ties 4. Temporary supports 5 are installed along two external walls of the building on two neighboring captures, for example, on the reconstructed “b” and the next, to be reconstructed “c”. The upper parts of the supports 5 along the walls of the building are combined with the guides mounted on them 7. Then, a protective tent 8 is erected over the reconstructed capture "b" of the building, resting it on the guides 7, and the old structures 9 are dismantled and new structures are erected 2. The tent 8 is moved to the next grasp "c" to be reconstructed, and temporary supports 5 and guides 7 are rearranged on the next grip "g". The dismantling of the tent 8 and temporary supports 5 with connections 4 is carried out after the reconstruction of building 1 along the entire length.
