Description

Technical Field

[0001] The present application relates to a modular building structure, belonging to the technical field of construction. Background Art

[0002] Modular construction is an important trend in the development of the construction industry in recent years. As one of the most prefabricated building forms in prefabricated buildings, modular construction has gradually developed into a hot spot in my country's construction industrialization with its unique advantages in construction, management and green environmental protection. Modular structural buildings have the advantages of high degree of integration, fast and efficient assembly, etc. The connection nodes between modules have a significant impact on the overall performance of the structure, so the design of the nodes is crucial. The development history of modular building structures at home and abroad has studied the structural form of connection nodes from the component assembly level, modular structure level and modular building level.

[0003] Existing technologies can be divided into welding connection, bolt connection, riveting connection, mortise and tenon connection, prestressed connection, adhesive connection, grouting connection, magnetic attraction connection, etc. The above connection processes can be used alone or in combination; based on the connection position, they can be divided into column top connection, column bottom connection, node box (a hexahedron of a certain material, generally located at the bottom and top of the column) connection, etc.

[0004] The existing connection construction is complex, the construction quality is difficult to guarantee, and the construction workers have high skills requirements. The quality of welding is not guaranteed at the construction site, and safety accidents are prone to occur. Bolt connection and mortise and tenon connection require high dimensional accuracy of the single module, and it is difficult to meet all the design requirements. Prestressed connection construction steps are many. The construction quality of adhesive connection and grouting connection is difficult to guarantee and is not environmentally friendly. Magnet attraction connection is not yet mature in the construction industry.

[0005] Therefore, in order to solve the above technical problems, it is necessary to provide a modular building structure to overcome the above defects in the prior art. Summary of the invention

[0006] The object of the present invention is to provide a modular building structure which can solve the construction complexity, ensure the construction quality and not impose excessive requirements on the skills of the construction workers.

[0007] To achieve the above object, the technical solution adopted by the present invention is: a construction method of a modular building structure, characterized in that it includes the following steps: 1) Install Velcro on two adjacent side walls of module 1; 2) Install the two modules 2 on the two side walls of module 1 respectively through Velcro; 3) Install Velcro on the two adjacent side walls between the two modules; 4) Install module 2 between two modules 2 to complete the whole module; One of the nylon fasteners is a connecting surface, and the other surface is a mounting surface. The connecting surface is used to mount the nylon fastener on module one, module two and module three, and the mounting surface is a hook surface or a fleece surface.

[0008] By adopting the above technical solution, the Velcro is in surface contact instead of point contact, the structure is more fully stressed, the redundancy is greater, and the contact surface is larger than the existing connection.

[0009] A modular building structure of the present invention is further configured as follows: a load is added to the entire module, and the force value of the Velcro connection point is analyzed and calculated.

[0010] A modular building structure of the present invention is further configured such that the shear strength between the hook surface and the rough surface is ≥77.0 N / cm2.

[0011] By adopting the above technical solution, the shear force value can be changed by adjusting the length, spacing and contact area of ​​the hook surface and the fleece surface. The shear force value is at least 7 times the requirement of the existing "Hook and Loop Fastener" (GB / T 23315-2009).

[0012] A modular building structure of the present invention is further configured as follows: the mounting surface is mounted on module one, module two and module three by means of gluing, bolting or riveting.

[0013] By adopting the technical solution, the compatibility of Velcro is improved.

[0014] The material of the Velcro of a modular building structure of the present invention is further configured as follows: the Velcro contains nylon, composite high-strength glass fiber content, added polytetrafluoroethylene, molybdenum disulfide and graphite.

[0015] By adopting the above technical solution, the shear force value of the Velcro can be changed.

[0016] A modular building structure of the present invention is further configured as follows: the Velcro fastener further comprises a stabilizer, an antioxidant and a carbon black filler.

[0017] By adopting the technical solution, the weather resistance of the Velcro is increased.

[0018] A modular building structure of the present invention is further configured as follows: composite high-strength glass fiber accounts for 15-30% of the total content of nylon fastener, polytetrafluoroethylene accounts for 0.5% of the total content of nylon fastener, molybdenum disulfide and graphite account for 0.3% of the total content of nylon fastener.

[0019] A modular building structure of the present invention is further configured such that the total content of the stabilizer, the antioxidant and the carbon black filler accounts for 0.1% of the total content of the Velcro.

[0020] Compared with the prior art, the present invention has the following beneficial effects: The modular building structure method of the present invention can solve the construction complexity, ensure the construction quality and not impose too high requirements on the skills of the construction workers.

[0021] The Velcro in the present invention makes the contact surface larger than the existing connection, not point contact but surface contact. The structure is more fully stressed and has greater redundancy. No additional nodes are required. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Please refer to the instruction manual Figure 1 To Attachment Figure 5 As shown, the present invention is a modular building structure, as shown in the first and second embodiments, including module one 1, two adjacent side walls of module one 1 are connected to module two 2 through nylon 4, module three 3 is connected between two modules two 2 through nylon 4, module one 1, two modules two 2 and module three 3 form an integral module, nylon 4 is not point contact but surface contact, the structure is more fully stressed, the redundancy is also large, and the contact surface is larger than the existing connection. One of the nylons is a connection surface, and the other surface is an installation surface. The connection surface is fixed with module one 1, module two 2 and module three 3 by means of gluing, bolting and riveting, which improves the compatibility of nylon 4, and external line stabilizers, antioxidants and carbon black fillings are provided between module one 1, module two 2 and module three 3 and nylon 4, which improves the weather resistance of nylon 4.

[0024] One of the nylon fasteners 4 is a connection surface, and the other surface is a mounting surface. The mounting surface includes a rough surface and a hook surface. The rough surface is mounted on the side wall of module 1, and the hook surface is mounted on the side wall of module 2. In this embodiment, the rough surface can also be mounted on the side wall of module 2, and the hook surface is mounted on the side wall of module 1. The rough surface and the hook surface are made of nylon material. The bonding effect of the rough surface and the hook surface is used to fix the monomer module and make it tightly combined. The nylon material is added with a composite high-strength glass fiber content, polytetrafluoroethylene, molybdenum disulfide, and graphite to change the shear value of the nylon fastener 4. In this embodiment, the composite high-strength glass fiber accounts for 15-30% of the total content of the nylon fastener 4, polytetrafluoroethylene accounts for 0.5% of the total content of the nylon fastener 4, molybdenum disulfide and graphite account for 0.3% of the total content of the nylon fastener 4, and the total content of the stabilizer, antioxidant and carbon black filler accounts for 0.1% of the total content of the nylon fastener. The top surface or bottom surface of the integral module is connected to another integral module through the nylon fastener 4.

[0025] The steps of installing a modular building structure of the present invention are as follows: First, establish the actual model of the modular building, add specific possible loads, run analysis and calculation, review the calculation results according to national standards, industry standards and product standards, read the force values ​​of the connection points between module 1, module 2 and module 3, such as tension and compression, bending moment, shear force and torque, and change the shear force value by adjusting the length, spacing and contact area of ​​the hook and fur surface of Velcro 4. The shear force value should be at least 7 times the requirement of the existing "Hook and Loop" (GB / T23315-2009), that is, the shear strength should be ≥77.0N / cm2. The length of the hook and fur surface should be increased by more than 10 times, leaving no gaps. The material composition ratio and additives of Velcro 4 can also be adjusted to change the shear force value. Increase the content of composite high-strength glass fiber, add additives such as polytetrafluoroethylene, molybdenum disulfide, graphite, etc., and the peel strength and fatigue resistance of Velcro 4 (after 1000 or 3000 times of clutch) do not need to be concerned. The compatibility of nylon with module 1, module 2, and module 3 is increased by gluing, bolting, and riveting. Its weather resistance is increased by adding UV stabilizers, antioxidants, and carbon black fillers.

[0026] The above specific implementation methods are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
