Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to the negative reinforcement mesh module for floor slab structure support and its construction method. Background Technology

[0002] The construction of building floor slab structures typically involves the erection of supports, installation of formwork, binding of floor slab reinforcement, pouring of concrete, and final curing, as well as inspection and acceptance at each stage.

[0003] During the construction of negative reinforcement for floor slab structural supports in the stage of tying floor slab reinforcement, construction personnel usually need to repeatedly check the design document parameters, process materials, lay out construction lines, check and measure and sort the reinforcement bars one by one on the work surface, lay the reinforcement bars one by one, tie the reinforcement mesh point by point with wire to form a reinforcement mesh, set up the negative reinforcement mesh support stools, and conduct construction verification. The construction process involves a large amount of information, is tedious and time-consuming, and affects the quality of reinforcement installation and the construction progress.

[0004] During the inspection and acceptance phase of the floor slab reinforcement, the inspection and acceptance personnel need to inspect the quality of the floor slab reinforcement according to the design parameters of the floor slab negative reinforcement in the engineering construction drawings. They need to measure and verify the installation spacing and diameter of the reinforcement. The inspection and acceptance process involves a large amount of information, is tedious and time-consuming, and affects the acceptance progress.

[0005] The negative reinforcement of the floor slab structure includes the main reinforcement and the distribution reinforcement. The ends of the main reinforcement are all anchored with a 7-shaped hook to form a single, short, gate-shaped reinforcement. Usually, the floor slab structure negative reinforcement mesh is stabilized by independently setting up support trestles between the negative reinforcement mesh and the formwork. The floor slab support negative reinforcement mesh made by this structure is difficult to resist construction loads. The reinforcement and support trestles are prone to deformation or displacement. In particular, after the negative reinforcement bends, it will affect the load-bearing capacity of the floor slab structure.

[0006] Since the negative reinforcement mesh of the floor slab structure support is formed by laying out lines, positioning and binding wires on the working surface, it is easy for the negative reinforcement mesh to deform, shift or sink under the action of construction loads (concrete pouring, construction machinery, materials and construction personnel), which affects the construction quality.

[0007] During the implementation of steel reinforcement projects, the processes of steel reinforcement fabrication, material management, installation, inspection and acceptance, and inspection tracking all extract information from the design documents (such as drawings) (the location, diameter, spacing, and length of the reinforcement). During implementation, each process needs to repeatedly search and verify this information, resulting in a large workload. Summary of the Invention

[0008] The purpose of this utility model is to provide a negative reinforcement mesh module for the support of building floor slab structures, which can realize integrated management of reinforcement information, reasonable structural stress, good stability, can be used in both cast-in-place and precast structures, eliminate the construction process of setting up support trestles, improve the construction environment of rebar tying, reduce the workload of work surface acceptance, and improve construction quality and speed.

[0009] The negative reinforcement mesh module for floor slab structure support of this utility model is implemented as follows:

[0010] The system includes an integrated reinforcing bar assembly, several distributed reinforcing bars, several short reinforcing bars resisting horizontal displacement, end triangular support trestles, middle triangular support trestles, location markers, and integrated management information. The integrated reinforcing bar assembly comprises several parallel straight reinforcing bars, several V-shaped reinforcing bars, and end bent reinforcing bars. One end of each straight reinforcing bar is connected to one end of an adjacent straight reinforcing bar via a first V-shaped reinforcing bar. The other end of the straight reinforcing bar is connected to the other end of an adjacent third straight reinforcing bar via a second V-shaped reinforcing bar. The end bent reinforcing bars are connected to the free ends of the straight reinforcing bars on the sides. The V-shaped reinforcing bars connected to the ends of two adjacent straight reinforcing bars form end triangular support trestles. Several distributed reinforcing bars are parallel and perpendicularly connected to several parallel straight reinforcing bars. There are two sets of middle triangular support trestles, each set containing several middle triangular support trestles, which are V-shaped. Connecting to the connection point of two adjacent distributed reinforcing bars on the same straight reinforcing bar, two sets of central triangular support trestles are located on both sides of the integrated reinforcing bar group. There are two or more sets of anti-horizontal displacement short reinforcing bars located in the middle of the integrated reinforcing bar group. The anti-horizontal displacement short reinforcing bars are vertical and connected to the connection point of the distributed reinforcing bars and the straight reinforcing bars. The height of the anti-horizontal displacement short reinforcing bars, the vertical height of the end triangular support trestles, the vertical height of the end bent reinforcing bars, and the vertical height of the central triangular support trestles are consistent. The position marking and integrated management information include the position of various reinforcing bars, the positioning scale of various reinforcing bars, the diameter of various reinforcing bars, the material of various reinforcing bars, the spacing of various reinforcing bars, the length of various reinforcing bars, the spacing and height between anti-horizontal displacement short reinforcing bars, the spacing and height between the end triangular support trestles, the spacing and height between the central triangular support trestles, the span and thickness of the floor slab used, the location of use, and the information number.

[0011] Preferably, the integrated reinforcing bar assembly, which includes several parallel straight reinforcing bars, several V-shaped reinforcing bars, and end-bent reinforcing bars, is formed by bending a single reinforcing bar as a whole.

[0012] Preferably, the location markers and integrated management information include information numbers with single symbols (such as ①, ③, etc.) to facilitate quick identification by users.

[0013] Preferably, easily identifiable positioning graduations are provided on the direct-load reinforcing bars at the connection and fixing positions corresponding to the design requirements, so as to accurately position and fix the negative reinforcement mesh module of the floor slab structure support during installation.

[0014] The construction method of the negative reinforcement mesh module for floor slab structure support of this utility model is as follows, including:

[0015] S1: After the engineering design documents are finalized, the construction site prepares a construction schedule based on the structural conditions in the design documents and informs the manufacturer of the negative reinforcement mesh module for the floor slab structure support and the relevant quality management parties.

[0016] S2: After the engineering design documents and construction schedule are finalized, the manufacturer of the floor slab support negative reinforcement mesh module shall prepare a floor slab support negative reinforcement mesh module manufacturing plan, and manufacture the floor slab support negative reinforcement mesh module outside the floor slab construction work surface in advance according to the design documents. After the quality acceptance is qualified, the location marking and integrated management information shall be marked and ready for use. The location marking and integrated management information, acceptance status and processing quantity shall be notified to the construction site of the floor slab construction work surface and relevant parties.

[0017] Since the S2 stage acceptance includes the location of various reinforcing bars, the positioning scale of various reinforcing bars, the diameter of various reinforcing bars, the material of various reinforcing bars, the spacing of various reinforcing bars, the length of various reinforcing bars, the spacing and height between short reinforcing bars resisting horizontal displacement, the spacing and height between end triangular support trestles, the spacing and height between middle triangular support trestles, the span and thickness of the floor slab used, the location of use, and the information number, the floor slab structure support negative reinforcement mesh module has met the requirements of the design document parameters. Therefore, the inspection and acceptance at each stage can eliminate the need to check the design parameters, reduce the workload of the later work surface, and improve the construction speed and the quality of the floor slab structure support negative reinforcement mesh module.

[0018] Because it is fabricated outside the floor slab construction site, the fabrication process is not affected by the floor slab construction site environment and construction progress, and can be carried out in a factory. Therefore, it can be carried out using automated equipment, resulting in high production efficiency and high quality.

[0019] S3: When the construction site reaches the corresponding structural component position according to the construction schedule, and after the installation of the floor slab structural formwork is completed, mark the corresponding position of the floor slab structural support negative reinforcement mesh module to be installed and the information number of the integrated management information at the corresponding position of the formwork. This ensures that the floor slab structural support negative reinforcement mesh module delivered and placed corresponds to the corresponding position (e.g., when the floor slab structural support negative reinforcement mesh module with information number ① needs to be placed on the building's 3rd axis or the floor slab structural support negative reinforcement mesh module with information number ③ needs to be placed on the building's B axis according to the design requirements, mark the corresponding position of the floor slab structural support negative reinforcement mesh module and the information number of the integrated management information at the corresponding position of the corresponding formwork so that the floor slab structural support negative reinforcement mesh module can be accurately delivered to the construction site).

[0020] S4: Match the position marks and integrated management information numbers on the template with the position marks and integrated management information numbers of the floor slab structural support negative reinforcement mesh module. After the structural beam steel reinforcement cage is settled and stabilized and the floor slab bottom reinforcement is installed, position and fix the floor slab structural support negative reinforcement mesh module according to the positioning scale on the direct-load steel reinforcement. The steel reinforcement of the structural beam steel reinforcement cage, the steel reinforcement of the floor slab bottom reinforcement and the steel reinforcement of the floor slab structural support negative reinforcement mesh module are inter-lapped and anchored to each other to complete the laying of the floor reinforcement cage. According to the actual needs of the site, simply use steel nails to fix the end triangular support stools and the middle triangular support stools to the template to ensure that the floor slab structural support negative reinforcement mesh module is installed firmly.

[0021] Since the quality of the negative reinforcement mesh module of the floor slab structure support has been inspected in the S2 stage, there is no need to look at the design document parameters (drawings) in the S4 stage, and the construction process is intuitive, simple and fast.

[0022] Since the negative reinforcement mesh module of the floor slab structure support already contains the fixed load-bearing structure with reasonable end triangular support trestles and middle triangular support trestles, the construction process of setting up end triangular support trestles and middle triangular support trestles is eliminated in the S4 stage, reducing the workload on the work surface and improving the construction speed.

[0023] Because the negative reinforcement mesh module of the floor slab structure support has corresponding positioning scales on it during the manufacturing process, the positioning can be directly used when installing the negative reinforcement mesh module of the floor slab structure support. Therefore, the use of a measuring tape is eliminated in the S4 stage, which improves the construction speed.

[0024] S5: After the floor slab reinforcement cage is completed, the acceptance phase of the floor slab reinforcement cage begins. The acceptance personnel check the location markings and integrated management information of the template with the location markings and integrated management information of the floor slab structure support negative reinforcement mesh module that has been installed, to confirm whether the information numbers match. At the same time, they can directly visually observe the positioning scale on the floor slab structure support negative reinforcement mesh module to check the accuracy of the acceptance and placement positioning.

[0025] Since the quality of the negative reinforcement mesh module of the floor slab structure support has been inspected in the S2 stage, there is no need to look at the design document parameters (drawings) in the S5 stage. It is only necessary to check on-site whether the information numbers correspond one by one. The inspection process is intuitive, simple and fast.

[0026] Since the negative reinforcement mesh module of the floor slab structure support has corresponding positioning scales during the manufacturing process, when checking and accepting whether the positioning of the negative reinforcement mesh module of the floor slab structure support is accurate, the S5 stage can be carried out by visually verifying the conformity, without having to look at the design document parameters (drawings), thus improving the speed of inspection and acceptance.

[0027] S6: After the floor steel reinforcement cage passes inspection, the floor concrete is poured. Because the negative reinforcement mesh module of the floor structure support has good load-bearing capacity, it is not easy to deform and sink under construction load, which reduces the need for adjusting and resetting the floor negative reinforcement during the concrete pouring process.

[0028] Compared with existing technologies, this utility model has the advantages of enabling integrated management of reinforcement information, reasonable structural stress, good stability, applicability to both cast-in-place and prefabricated structures, eliminating the need for supporting trestles during construction, improving the construction environment for rebar tying, reducing the workload of work surface acceptance, and improving construction quality and speed.
