Description

Technical Field

[0001] The present application relates to the technical field of integrated buildings, and in particular to a partition-type concrete frame connection node and a building structure. Background Art

[0002] Integrated buildings, also known as movable or removable buildings, are a building model that prefabricates concrete structures such as walls and roofs in factories, and processes load-bearing structures represented by steel structures according to design requirements, so that complete sets of houses can be quickly assembled on the construction site. The characteristics of integrated buildings that are removable, movable, and do not damage the land have realized the transformation of houses from "real estate" to "movable property" for thousands of years, and realized the separation of "property" and "land" in "real estate" for thousands of years.

[0003] Traditional integrated houses are mainly composed of multiple systems such as structural system, ground system, floor system, wall system and roof system, and each system is composed of several concrete structural parts. The prefabricated concrete structural parts can be quickly assembled on the construction site, but in the actual construction process, the connection nodes of the integrated building still need to be poured on site, so a lot of wet work is still required on the construction site. Summary of the invention

[0004] In order to reduce wet work at the construction site, the purpose of the present application is to provide a partition type concrete frame connection node and building structure.

[0005] In the first aspect, the present application provides a diaphragm type concrete frame connection node adopts the following technical solution:

[0007] By adopting the above technical solution, the tension plate is connected to the upper connection part through the upper bolts and connected to the lower connection part through the lower bolts, thereby achieving a stable connection between the upper connection part and the upper connection part. Since the upper connection part and the lower connection part can be directly prefabricated in the corresponding concrete structure, the construction site only needs to install the tension plate, the upper bolts and the lower bolts, thereby making the connection node of the present application have the effect of reducing the wet work required on the connection node at the construction site.

[0008] Optionally, the upper connecting part includes an upper shear plate and an upper panel arranged on the upper surface of the upper shear plate, the upper panel is penetrated by an upper connecting hole for connection with the upper bolt, and the upper bolt is connected to the upper connecting hole; the lower connecting part includes a lower shear plate and a lower panel arranged on the lower surface of the lower shear plate, the lower panel is penetrated by a lower connecting hole for connection with the lower bolt.

[0009] By adopting the above technical scheme, when connecting two upper and lower adjacent concrete structural members, first align the upper tensile hole of the tensile plate with the upper connecting hole, and then the upper bolts simultaneously connect the upper tensile hole and the upper connecting hole to achieve the connection between the tensile plate and the upper panel, and then align the lower tensile hole of the tensile plate with the lower connecting hole, and the lower bolts simultaneously connect the lower tensile hole and the lower connecting hole to achieve the connection between the tensile plate and the lower panel, thereby completing the connection between the upper panel and the lower panel to achieve the connection between the upper connecting part and the lower connecting part, thereby further simplifying the connection operation between the upper connecting part and the lower connecting part.

[0010] Optionally, the upper shear plate is provided with a shear groove, and the lower shear plate is provided with a shear block for plugging and cooperating with the shear groove.

[0011] By adopting the above technical solution, the shear block is embedded in the shear groove to limit the horizontal displacement of the upper shear plate after being connected to the lower shear plate, thereby further improving the connection stability between the upper connecting part and the lower connecting part.

[0012] Optionally, the lower shear plate is provided with a shear groove, and the upper shear plate is provided with a shear block for plugging and cooperating with the shear groove.

[0013] By adopting the above technical solution, the shear block is embedded in the shear groove to limit the horizontal displacement of the upper shear plate after being connected to the lower shear plate, thereby further improving the connection stability between the upper connecting part and the lower connecting part.

[0014] Optionally, the number of the upper and lower connecting structures is at least two, and the connecting node also includes a connecting plate for connecting multiple upper and lower connecting structures, the connecting plate is clamped between the corresponding upper connecting part and the corresponding lower connecting part, and the connecting plate is provided with a plurality of connecting holes for the shear blocks to pass through, and each upper and lower connecting structure corresponds to one connecting hole.

[0015] By adopting the above technical solution, all the shear blocks of the upper and lower connecting structures need to pass through the corresponding connecting holes on the connecting plate when connected to the corresponding shear grooves, so as to realize the horizontal connection of the upper and lower connecting structures corresponding to the shear blocks. As a result, the stability of the upper and lower connections of the connecting nodes is ensured while the stability of the connection between the two horizontally adjacent upper and lower connecting structures is improved.

[0018] Optionally, the anti-shear block is a rectangular block, a cylindrical block or an elliptical block, and the shape of the anti-shear groove is adapted to the anti-shear block.

[0019] By adopting the above technical solution, when the shear block is set as a rectangular block, the shear groove is a rectangular groove adapted thereto, and the rectangular shape can limit the relative deflection between the upper connecting part and the lower connecting part after being connected, thereby improving the connection stability of the upper connecting part and the lower connecting part.

[0020] When the shear block is set as a cylindrical block, the shear groove is a cylindrical groove adapted thereto.

The elliptical setting combines the cylindrical shear force dispersion function with the rectangular rotation restriction function, thereby improving the shear resistance of the upper and lower connecting parts while improving the connection stability.

[0022] Optionally, the bottom of the shear groove is closed.

[0023] By adopting the above technical solution, the bottom of the shear groove is closed, so that the flow of concrete into the shear groove can be effectively reduced during the prefabrication of the connection node, thereby further improving the use stability when the upper connection part and the lower connection part are connected.

[0025] A building structure comprises a plurality of transversely and / or longitudinally distributed concrete structural members, wherein adjacent concrete structural members are connected via the above-mentioned connection nodes.

[0026] By adopting the above technical solution, the upper connection part and the lower connection part of the connection node are already made in the concrete structure when the concrete structure is prefabricated. The construction site only needs to use tensile plates, upper bolts and lower bolts for connection, thereby effectively reducing wet operations on the construction site.

[0027] Optionally, the concrete structural member includes a base plate, frame columns, frame beams and a top plate, the number of the frame columns and the number of the frame beams are both four, the four frame columns are respectively arranged at the four peripheral corners of the upper surface of the base plate, the frame beam connects the upper ends of two adjacent frame columns, the four frame beams enclose an upper opening, the top plate closes the upper opening, and the upper connecting part and the lower connecting part are installed in corresponding frame columns.

[0028] By adopting the above technical scheme, the bottom plate frame columns, frame beams and top plate are all prefabricated separately and then assembled into concrete structural parts, while the upper connecting part and the lower connecting part are only prefabricated in the frame columns, and the prefabrication process of the bottom plate, frame beams and top plate remains unchanged, thereby reducing the difficulty of prefabrication of concrete structural parts.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] The tensile plate is connected to the upper connection part through the upper bolts and connected to the lower connection part through the lower bolts, thereby realizing a stable connection between the upper connection part and the lower connection part. Since the upper connection part and the lower connection part can be directly prefabricated in the corresponding concrete structure, the construction site only needs to install the tensile plate, the upper bolts and the lower bolts, thereby making the connection node of the present application have the effect of reducing the wet work required on the connection node at the construction site;

[0031] When the shear blocks of all upper and lower connection structures are connected to the corresponding shear grooves, they all need to pass through the corresponding connection holes on the connection plate, so as to realize the connection of the upper and lower connection structures corresponding to the shear blocks in the horizontal direction, thereby ensuring the upper and lower connection stability of the connection nodes while improving the connection stability of the two upper and lower connection structures adjacent to each other in the horizontal direction;
