Description

[0001] The invention relates to the technical field of modern building construction, and in particular to a construction structure and method of rows of independent buttress columns highly integrated into a factory building. Background Art

[0002] At present, there are rows of buttress structures on both sides of the reactor building of the nuclear power plant. The buttresses above the roof elevation of the surrounding buildings are independent buttresses. The buttresses below the roof elevation of the surrounding buildings are located in the surrounding buildings. The height of the buttress structure is consistent with the gable of the reactor building from bottom to top. Since the reactor building is constructed first, the buttresses are used to increase the rigidity of the gable of the reactor building to resist the lateral stress of the steel arch on the gable. The buttress structure needs to be constructed together with the gable of the reactor building, which is much earlier than the construction of the main structure of the surrounding buildings.

[0003] The buttress column structure is designed to be integrated with the main structure of the surrounding factory buildings. The traditional standard layer construction method of one wall and one slab will take a long time to complete and will not meet the requirements of synchronous construction of buttress columns and gables. Therefore, when constructing the buttress column structure, construction joints must be set at the connection with the surrounding factory buildings, and the space of the surrounding factory buildings must not be occupied to build operating platforms or passages, otherwise it will affect the construction of the main structure of the surrounding factory buildings; the buttress column height can generally reach 70m, and the maximum construction height difference with the surrounding factory buildings can reach 40m, so it cannot be constructed by setting up scaffolding. Summary of the invention

[0013] Furthermore, a vertical passage with a scaffolding inclined ladder is set up on the supporting steel beam of the room; the bottom of the scaffolding ladder is buckled with a top support to fix the scaffolding steel pipe, a platform is set at the turning of the passage, railings and toeboards are set on both sides of the inclined passage and the periphery of the platform, and the periphery of the scaffolding ladder along the frame is fully enclosed with a dense mesh safety net.

[0014] Furthermore, the operating platform uses longitudinal scaffolding steel pipes and horizontal scaffolding steel pipes to form an operating platform scaffolding steel pipe frame, wherein the longitudinal scaffolding steel pipes and the horizontal scaffolding steel pipes are connected by cross fasteners, and scaffolding steel springboards are laid on them; the operating platform scaffolding steel pipe frame is connected into a whole by scaffolding steel pipes and the bottom triangular support tooling hanger or channel I-beam.

[0015] Furthermore, the tooling hanger cone is embedded in the inner side of the template of the independent buttress column through a bent pull rod installed in the tooling hanger cone, the tooling hanger screw passes through the hanger mounting hole on the independent buttress column and is connected to the tooling hanger cone, the tooling hanger screw is tightened and fixed to the tooling hanger cone by a disc nut and a gasket, and a triangular support tooling hanger is installed on the outer end of the tooling hanger screw.

[0016] Furthermore, the outer end of the tooling hanger screw rod is connected to the triangular support tooling hanger through the length of the scaffolding steel pipe, so that the triangular support tooling hangers on the same side are connected into a whole.

[0017] Furthermore, the staggered platform is constructed with steel sections and scaffolding supports. The staggered platform is supported by cantilevered I-beams embedded in the lower wall. The scaffolding steel pipes are fixed in the form of top supports and inverted buckles.

[0018] Preferably, a construction joint is provided at the connection between the gable and the independent buttress column, and the independent buttress column dowel bars include mechanical joints.

[0019] Furthermore, the rows of independent buttresses are divided into a number of rooms by partition walls, walls and floor slabs, and the rooms are used as functional rooms in the factory.

[0020] A second aspect of the present application provides a method for constructing rows of independent buttress columns that are highly integrated into a factory building, comprising the following steps:

[0021] Carry out gable construction first;

[0022] After the gable construction, rows of independent buttresses are constructed;

[0023] The operating platform composed of triangular support tooling hangers, cantilevered I-beams and channel I-beams is constructed layer by layer to form rows of independent buttress columns; when constructing the next layer of independent buttress columns, the cantilevered I-beams and tooling hanger cones are pre-embedded; during construction, the triangular support tooling hangers are installed on the tooling hanger cones, the channel I-beams are installed on the cantilevered I-beams, and the operating platform composed of scaffolding steel pipes and steel springboards is installed on the triangular support tooling hangers and channel I-beams;

[0026] Construction of independent buttress columns is staggered;

[0027] Set up scaffolding support and construct the first height floor;

[0028] Scaffolding support is set up on the top of the first-height floor slab to construct the second-height floor slab;

[0029] Finally, the partition walls, walls and floor slabs between the rows of independent buttresses below the roof level of the surrounding factory buildings are constructed.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The rows of independent buttress columns of the present invention do not occupy space, and the independent buttress columns and the surrounding structures can be constructed in parallel, or the buttress columns can be constructed first, thus shortening the construction period.

[0033] The original traditional scaffolding construction method wastes a lot of manpower and materials, occupies space, cannot meet the requirements of synchronous construction of surrounding structures, affects the construction period, and requires the construction of super-high scaffolding, which is very dangerous. The present invention is a construction structure of rows of warehouse-type buttress columns, and combines the operating platform and the passage into one, which can be used in rotation with the construction level, saving construction materials and ensuring construction quality and safety.

[0034] The present invention embeds a supporting steel beam in the buttress column, and sets up a steel pipe scaffolding inclined ladder on the supporting steel beam, so as to fully utilize the internal space, facilitate vertical up and down passage of personnel, and improve efficiency.
