The frame columns are fully prefabricated, the frame beams are composite beams, the longitudinal reinforcement of the upper and lower columns is connected by sleeve grouting, and the beam-column nodes are cast in concrete later. During the construction of this system, temporary supports and formwork need to be set up on site, the on-site work volume is large, and the construction period is long. In addition, the frame columns in the steel frame structure generally use rectangular steel pipe columns or H-shaped steel columns, the steel beams use H-shaped cross-sections, and the beam-column connection can be a short beam, flange welded web bolting or a fully welded connection. This type of system has a short construction period, but fire prevention and anti-corrosion measures need to be taken, and the construction cost is relatively high.

[0056] Example

[0057] Reference Figure 1 -Attached Figure 3 The embodiment of the utility model provides an assembled concrete frame structure, which comprises: a prefabricated frame column 1 and a prefabricated frame beam 2, wherein the side of the prefabricated frame column 1 has a node area for splicing with the prefabricated frame beam 2, and the prefabricated frame beam 2 has a node end for splicing with the prefabricated frame column 1, and the bottom and top of the node end are respectively provided with a first groove 201 and a second groove 2022; a support member 3, which comprises a mutually perpendicular connecting end plate 31 and a supporting plate 32, and the connecting end plate 31 is pre-buried in the node area of ​​the prefabricated frame column 1; a first connecting member 4 , adapted and pre-embedded in the first groove 201 of the prefabricated frame beam 2, the first connecting member 4 is overlapped on the support plate 32 of the support member, and the first connecting member 4 and the connecting end plate 31 are separated by a first filling gap; and a second connecting member 5, adapted and pre-embedded in the second groove 2022 of the prefabricated frame beam 2, and the second connecting member 5 and the node area are separated by a second filling gap; wherein, the first connecting member 4 is locked and fixed with the connecting end plate 31 and the node area by a threaded locking member 6, and the second connecting member 5 is locked and fixed with the node area by a threaded locking member 6.

[0058] Specifically, the prefabricated concrete frame structure provided in this embodiment mainly includes a prefabricated frame column 1 and a prefabricated frame beam 2. The prefabricated frame column 1 can be a cubic column structure with a rectangular cross-section and extending longitudinally, and its bottom end is fixed to a preset position on the construction site, specifically, it can be fixed to the foundation or other prefabricated frame columns 1. The prefabricated frame column 1 serves as a longitudinal load-bearing member and can effectively transfer the weight of the building to the foundation; the prefabricated frame beam 2 can be a cubic beam structure with a rectangular cross-section and extending transversely, and its end is connected to the prefabricated frame column 1 to carry other components of the prefabricated building and transmit force laterally; Figure 2 Schematically shows the precast concrete parts in the precast frame column 1 and the precast frame beam 2.

[0059] In the prefabricated concrete frame, the way of connecting beams and columns is the fundamental difference between prefabricated structures and cast-in-place structures, and is also the core stress-bearing part that affects the seismic performance of the overall structure. In order to solve the problems of large on-site work volume and long construction period in the current method of prefabricating beams and columns and casting nodes later, as well as the need to take fire prevention and anti-corrosion measures and high construction cost in the form of beam-column connection with short beams, flange welded web bolting or full welding, in the technical scheme adopted by the utility model, the node area where the prefabricated frame column 1 and the prefabricated frame beam 2 are spliced ​​is connected by a support member 3, a first connecting member 4 and a second connecting member 5, wherein the support member 3 is fixed to the prefabricated frame column 1, and the first connecting member 4 and the second connecting member 5 are fixed to the prefabricated frame beam 2, and are connected and fixed in conjunction with the threaded locking member 6, thereby realizing a dry connection in the node area. During construction, the prefabricated frame beam 2 can be overlapped on the support member 3 and fixed by the threaded locking member 6, without the need for temporary support, saving construction time and cost.

[0060] Specifically, the side of the prefabricated frame column 1 has a node area located in the node area for splicing with the prefabricated frame beam 2; the prefabricated frame beam 2 is set as a notched beam, and the top and bottom of the node end of the prefabricated frame beam 2 are respectively provided with a first groove 201 and a second groove 2022, and the shapes of the two can be different, so as to be used for pre-embedded first connecting member 4 and second connecting member 5 respectively; the support member 3 can be configured as a steel structure, which includes a connecting end plate 31 and a supporting plate 32 perpendicular to each other, and the two can be fixed as a whole by welding, and the connecting end plate 31 is fixed to the prefabricated frame column 1, and its width in the first direction x is adapted to the size of the prefabricated frame beam 2 in this direction (the first direction x is the attached Figure 1The direction indicated by the double-headed arrow x in the figure is perpendicular to the extension direction of the prefabricated frame beam 2 and the prefabricated frame column 1 respectively); the support plate 32 can be just located at the bottom end of the connecting end plate 31, or can also be set higher than the bottom end of the connecting end plate 31. The support plate 32 is used to provide support for the node end of the prefabricated frame beam 2 when the prefabricated frame beam 2 is spliced ​​with the prefabricated frame column 1; the first connecting member 4 is embedded in and fixedly connected to the first groove 201 of the prefabricated frame beam 2. When the prefabricated frame beam 2 is spliced ​​with the prefabricated frame column 1, the first connecting member 4 is overlapped on the support plate 32 of the supporting member 3; the second connecting member 5 is embedded in and fixedly connected to the second groove 2022 of the prefabricated frame beam 2; the first connecting member 4 is locked and fixed to the connecting end plate 31 and the node area by a threaded locking member 6, and the second connecting member 5 is locked and fixed to the node area by a threaded locking member 6, and the first connecting member A first filling gap is reserved between the connecting end plate 31 of the prefabricated frame beam 4 and the support member 3, and a second filling gap is reserved between the second connecting member 5 and the node area. The first filling gap and the second filling gap are used to pour filling materials. The filling materials can fill all gaps, spaces and cracks in the node area to enhance the rigidity and stability of the node area, avoid loosening and damage of the connection structure in the node area, and can wrap the connection structures such as the support member 3, the first connecting member 4 and the second connecting member 5 in the node area so that the connection structure is not exposed. The filling material has good corrosion resistance and oxidation resistance, so there is no need for anti-corrosion and fire prevention treatment, which further reduces the construction cost; wherein, the first filling gap and the second filling gap refer to the interval space reserved in the extension direction of the prefabricated frame beam 2, and the sizes of the first filling gap and the second filling gap can be equal or unequal.

[0061] During the construction of the above-mentioned prefabricated concrete frame structure, the prefabricated frame column 1 can be first hoisted to the construction site, and then the prefabricated frame beam 2 can be hoisted, and the node end of the prefabricated frame beam 2 corresponds to the node area of ​​the prefabricated frame column 1 and the first connecting member 4 dropped to the node end is overlapped on the support plate 32 of the support member 3, and then fixedly connected by a threaded locking member 6, and finally poured with filling material to fill the gaps, spaces and cracks in the connection structure of the node area and the first groove 201, the second groove 2022, etc.

[0062] Among them, the support member 3 is embedded in the prefabricated frame column 1, and the first connecting member 4 and the second connecting member 5 are embedded in the prefabricated frame beam 2. When the beams and columns are spliced ​​at the construction site, there is no need to perform the installation steps of the support member 3, the first connecting member 4 and the second connecting member 5. This improves the construction efficiency, ensures the position accuracy and connection quality of the connecting structure, and is also beneficial to enhancing the stability and bearing capacity of the structure.

[0063] Among them, the shape setting of the first connecting member 4 and the second connecting member 5 needs to ensure its own strength and the fixing strength between it and the prefabricated frame beam 2, and the setting of the first connecting member 4 also needs to improve the lap stability between it and the support member 3, and the first connecting member 4 and the second connecting member 5 also need to form an operating space for connecting the threaded locking member 6.

[0064] For further information, see Attachment Figure 1 and attached Figure 2 In a specific implementation, the bottom surface of the connecting end plate 31 can be set flush with the bottom surface of the prefabricated frame beam 2, so that the support member 3 does not protrude from the prefabricated frame beam 2 when it is matched with the prefabricated frame beam 2, thereby improving the aesthetics of the node area; at the same time, such a design can also completely wrap the support member 3 when pouring the filling material so that it is not exposed.

[0065] According to the above, the embodiment of the utility model proposes an assembled concrete frame structure, in which the node area where the prefabricated frame column 1 and the prefabricated frame beam 2 are spliced ​​is connected and locked by connecting structures such as the support member 3, the first connecting member 4 and the second connecting member 5 in cooperation with the threaded locking member 6. During construction, the node end of the prefabricated frame beam 2 can be overlapped on the support member 3, and the support member 3 participates in the shear resistance at the end where the prefabricated frame beam 2 is located, so the force is more reasonable, and there is no need to set up a temporary supporting structure, which can reduce construction time and cost; the node location is a dry connection, without traditional formwork engineering, concrete pouring on site and other large-scale wet operations, which can effectively improve construction efficiency and is conducive to energy conservation, emission reduction and environmental protection; after the node area is connected by the threaded locking member 6, the connection structure of the node area can be wrapped inside by pouring filling material, so that the connection structure is not exposed, so there is no need for anti-corrosion and fire prevention treatment, which can reduce construction costs.

[0068] Among them, refer to the attached Figure 2, the exposed end of each connecting sleeve 7 can be set to be flush with the splicing surface of the prefabricated frame column 1, and the exposed surface of the end plate of the support member 3 can also be set to be flush with the splicing surface of the prefabricated frame column 1; the connecting end plate 31 of the connecting sleeve 7 and the support member 3 can be anchored in the prefabricated frame column 1 by the anchor steel bar 11, and the anchor steel bar 11 can be in a bent form, a through form or a mechanical anchoring form, which can be set according to the location of the node area. The end of the straight anchor steel bar 11 can be provided with an anchor plate 12, as shown in the attached Figure 2 As shown, the pull-out resistance of this type of anchor steel bar 11 after pouring is increased.

[0069] Among them, refer to the attached Figure 2 The threaded locking member 6 may include: a screw 61, a first nut 62, a second nut 63 and a gasket 64. After the first connecting member 4 of the prefabricated frame beam 2 is stably overlapped to the support member 3, the first nut 62 is installed on the screw 61, and the screw 61 is threadedly connected in the connecting sleeve 7 corresponding to the first connecting hole 3101 and the second connection. The first nut 62 on the screw 61 is located between the support member 3 and the first end plate 41, and the screw 61 is further threadedly connected in the connecting sleeve 7 corresponding to the third connecting hole 5101. The first nut 62 on the screw 61 is located between the prefabricated frame column 1 and the second end plate 51, and then the gasket 64 and the second nut 63 are respectively installed on the screw 61, and the first nut 62 and the second nut 63 are respectively tightened, and the first filling gap and the second filling gap are reserved, so as to complete the convenient and reliable connection of the threaded support member 3.

[0070] For further information, see Attachment Figure 3 -Attached Figure 6 In a specific implementation, the support member 3 has a stiffening rib 33 connecting the connecting end plate 31 and the support plate 32 in the middle part in the first direction x; the node end of the prefabricated frame beam 2 has a third groove 203 corresponding to the stiffening rib 33, and the second groove 2022 includes a first groove body 2011 and a second groove body 2012 which are arranged on both sides of the third groove 203 and are not connected. The number of the first connecting members 4 is two and they are pre-embedded in the first groove body 2011 and the second groove body 2012 respectively; wherein, there is a third filling gap between the stiffening rib 33 and the third groove 203.

[0071] Specifically, in order to improve the support strength and shear resistance of the support member 3, a stiffening rib 33 can be provided at the middle position of the support member 3 in the first direction x. The stiffening rib 33 can be a plate-like structure and can be welded and fixed to the connecting end plate 31 and the supporting plate 32 of the support member 3, respectively. The stiffening rib 33 can be provided to be perpendicular to the connecting end plate 31 and the supporting plate 32, respectively. The provision of the stiffening rib 33 can improve the rigidity of the support member 3 to effectively resist external loads and deformation; wherein the stiffening rib 33 has an inclined portion on one side facing the prefabricated frame beam 2, as shown in the attached Figure 4 As shown, the structural strength and bearing capacity can be further improved, and the load of the "L"-shaped structure formed by connecting the end plate 31 and the support plate 32 can be dispersed, so that the force is more uniform and the stability of the structure is improved.

[0072] Among them, in order to cooperate with the setting of the stiffening rib 33 on the support member 3, the technical solution adopted by the utility model is as follows: Figure 3 The node end of the prefabricated frame beam 2 has a third groove 203 corresponding to the stiffening rib 33. When the prefabricated frame beam 2 falls to the first connecting member 4 and the supporting member 3, the stiffening rib 33 is inserted into the third groove 203; the first groove 201 includes a first groove body 2011 and a second groove body 2012 which are arranged on two opposite sides of the third groove 203 in the first direction x and are not connected. The number of the first connecting member 4 is two, as shown in the attached figure. Figure 3 and 7 As shown, the two are symmetrically arranged and are respectively embedded in the first trough body 2011 and the second trough body 2012, and the two first connecting members 4 respectively correspond to a part of the connecting sleeve 7 in the sleeve assembly located on the bottom side, so as to be locked and fixed with the connecting end plate 31 and the node area respectively. For example: when the sleeve assembly includes two connecting sleeves 7, a second connecting hole 4101 is respectively opened on the first end plate 41 of the two first connecting members 4; wherein, there is a third filling gap between the stiffening rib 33 and the third groove 203, which is used to pour filling material to enhance the rigidity and stability of the area.
