Description

Technical Field

[0001] The utility model relates to the technical field of steel structure modular buildings, in particular to an insertion type grouting connection structure used for steel structure modular buildings. Background Art

[0002] Steel structure modular buildings are an advanced stage of the development of building industrialization and are highly integrated prefabricated buildings. Steel structure modular buildings use functional modules as basic units. They can be used alone or in different combinations in the horizontal and vertical directions to form spacious use spaces. They are temporary or permanent buildings for turnover use. Modular steel structure buildings adopt modular design, factory production, and assembly construction. The processing of module units is completed in the factory, transported to the construction site, hoisted into place with lifting equipment, key nodes and pipelines between modules are connected, and the assembly of module units is completed by processing the joints. The construction quality is high and the construction speed is fast.

[0003] Compared with prefabricated concrete structures, modular steel structures do not require wet work on site, are quick to install, have more controllable quality, and are made of recyclable ductile materials. In addition to being environmentally friendly, they also have excellent seismic resistance. At the same time, compared with concrete structures, modular steel structures have smaller cross-sectional dimensions while ensuring mechanical properties, allowing for larger indoor usable space.

[0004] The construction site of steel structure modular building only needs to connect adjacent modules to form a whole, so the connection performance between modules is crucial to ensure the integrity of the building structure. In the past, steel structure modular buildings mainly adopted the form of multi-bolt connection or bolt connection combined with on-site welding, which had high requirements for error control at each stage. The more bolt connection holes or other installation holes were reserved, the higher the production accuracy control requirements, and the higher the deformation control requirements for transportation, stacking and hoisting, which greatly affected the mechanical properties of the connection nodes and the construction progress.

[0048] In order to better explain the utility model and facilitate understanding, the utility model is described in detail below with reference to the accompanying drawings and through specific implementation methods. Figure 1 The orientation is used as a reference.

[0049] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0050] The utility model provides an insertion type grouting connection structure for a steel structure modular building, wherein the steel structure modular building comprises a plurality of modules, and adjacent modules are fixedly connected. The module comprises a module column 10 and a module beam 11 perpendicular to the module column 10, and the module column 10 and the module beam 11 constitute a structural frame of the module. A first module beam 12 arranged along a first direction and a second module beam 13 arranged along a second direction are fixedly arranged at the end of the module column 10, and in this embodiment, the first module beam 12 is perpendicular to the second module beam 13.

[0051] The insertion type grouting connection structure also includes a connector 14, which is inserted into the installation cavity of the adjacent module column 10 to connect the adjacent module columns 10. The two upper and lower adjacent module columns 10 are fixedly connected by the connector 14, and the installation cavity is filled with grouting material to improve the connection strength between the module column 10 and the connector 14. While ensuring the connection strength, the construction process is reduced, the fault tolerance of the construction operation is improved, and the connection of the building module is more convenient.

[0052] The connecting member 14 includes a main rod 201 located in the middle and a plurality of plug-ins 203 arranged at equal intervals on the outer edge of the main rod 201 along the circumference of the main rod 201. The main rod 201 is fixedly connected to the plug-in 203, and the connecting member 14 is plugged into the inner wall of the installation cavity through the plug-in 203.

[0053] The main rod 201 is a circular steel tube with a hollow interior, located at the axis of the connector 14, and the plug-in 203 is arranged at equal intervals along the circumference of the main rod 201, and the plug-in 203 is connected to the cavity in the middle of the main rod 201. A plurality of second grouting holes 204 are arranged on the side wall of the plug-in 203 to facilitate the diffusion of grout to the surroundings during the grouting operation, so that the installation cavity in the module column 10 and the connector 14 are connected as a whole.

[0054] The main rod 201 has a plurality of first slurry holes 202 arranged at equal intervals along the circumferential direction. The first slurry holes 202 are located between adjacent plug-ins 203. The slurry holes 202 are used to facilitate the flow of grouting material in the installation cavity in the module column 10 during grouting operations, so that the grouting material can fill the installation cavity faster.

[0055] The end of the plug 203 is fixedly provided with a plug flange 205, which is used to be plugged into the module column 10. Each inner wall of the installation cavity is provided with a slot 101 corresponding to the plug 203, and the slot 101 is used to plug the plug flange 205, so that the connector 14 can be fixed on the inner wall of the module column 10, which is convenient for subsequent grouting.

[0056] A spacer bar 207 is provided in the middle of the connecting member 14, and the spacer bar 207 is fixed around the outer edge of the plug-in flange 205. The shape of the spacer bar 207 matches the module column 10, and is used to seal the connecting gap between two adjacent module columns 10 above and below, so that the sealing of the connection between the module columns 10 is better, and overflow from the gap is avoided during grouting.

[0057] Optionally, a spacer bar 207 of a corresponding shape may be selected according to the actual number of connected modules. When multiple modules are connected, the spacer bars 207 of multiple connectors may be integrally arranged.

[0058] The interior of the module column 10 is a hollow structure. A mounting cavity for mounting a connector 14 is formed by fixing a partition 103 inside the module column 10 and the side wall of the module column 10. When mounting the connector 14, a first grouting hole 104 for inserting a grouting conduit 107 is provided on the partition 103 located above the connector 14, and no first grouting hole 104 is provided on the partition 103 located below the connector 14, so that the grouting material injected from above can be retained in the mounting cavity.

[0059] The four corners of the partition 103 located on the upper part of the connecting member 14 are also provided with exhaust holes 105, which are beneficial to exhaust during the grouting operation.

[0060] Furthermore, a second grouting hole 106 for inserting a grouting tube 107 is provided on the side wall of the module column 10 located at the upper part of the connecting piece 14. The grouting tube 107 passes through the second grouting hole 106 and the first grouting hole 104 and is inserted into the main rod 201 from the middle of the partition 103. The grouting material is poured into the main rod 201 through the grouting tube 107, and then diffused into the plug-in 203 and the installation cavity through the grouting hole 202 on the main rod 201. The grouting material in the plug-in 203 diffuses to the surroundings through the second grouting hole 204, thereby increasing the grouting speed and allowing the grouting material to evenly fill the installation cavity.

[0061] A first bolt group 206 is further provided between adjacent plug-ins 203 , and the first bolt group 206 is used to enhance the connection strength between the connecting member 14 and the grouting material.

[0062] A second bolt group 102 is provided on the inner side wall of the installation cavity. The second bolt group 102 is located on both sides of the slot 101. The second bolt group 102 is used to enhance the connection strength between the module column 10 and the grouting material.

[0063] The insertion type grouting connection structure provided by the utility model is applied to the steel structure module. The installation of the upper and lower module splicing nodes of the steel structure module includes the following steps:

[0064] Step 1: Processing the joint nodes of the upper and lower modules, including the installation cavity of the module column 10 located at the lower layer and the installation cavity of the module column 10 located at the upper layer;

[0065] Step 2: a first grouting hole 104, a second grouting hole 106 and an exhaust hole 105 for inserting a grouting conduit 107 are provided on the module column 10 located at the upper layer;

[0066] Step 3: After the module on the lower layer is installed, insert the bottom end of the connector 14 into the installation cavity at the top of the module column 10 on the lower layer, and then hoist the module on the upper layer to the installation position, so that the position of the module column 10 on the upper layer corresponds to the position of the module column 10 on the lower layer, and gradually lower the hoisted module so that the module column 10 is plugged into the upper part of the connector 14.

[0067] Step 4: After the upper steel structure module is placed, high-strength self-compacting grouting material is poured from the top of the installation cavity through the grouting conduit 107 until the installation cavity of the upper and lower module splicing nodes is filled, thereby completing the connection of the upper and lower module splicing nodes.

[0068] Optionally, the number of modules and the locations where the modules are installed are selected according to the actual needs of the steel structure modular building.

[0069] The utility model provides an insertion type grouting connection structure for steel structure modular buildings. An installation cavity is arranged in a module column 10 and connected by a connecting piece 14. The installation is simple and convenient, and the construction efficiency is improved.

[0070] By combining the main rod 201, the plug-in 203 and the plug-in flange 205, the connector can be plugged into the module column 10, which facilitates the fixing of the module column 10 during grouting.

[0071] By arranging a plurality of grouting holes on the main rod 201 and the plug-in 203, the grouting liquid can be freely diffused in the installation cavity during the grouting operation, so that the grouting material can fill the installation cavity faster and improve the grouting efficiency.
