DETAILED DESCRIPTION

[0048] The corbel structure is an external cantilever structure used as a beam tow. For example, a corbel is set on the column to place or support the hanging beam to meet the suspension, installation and support force of the hanging beam during the construction process. However, as a supporting and force-transmitting structure, the corbel structure cannot be removed after the column and beam are connected. It will be exposed outside the overall column and beam, affecting the beauty of the overall structure and occupying unnecessary space. Its application in public buildings and multi-story residential buildings is greatly limited.

[0049] The assembled frame structure provided by the embodiment of the present disclosure does not adopt a corbel structure, but instead achieves quick connection and stable screw connection by arranging adaptive connection components on the prefabricated frame columns and prefabricated frame beams, and then fills the assembly gaps with a filling part to wrap each connection component, thereby achieving quick connection between columns and beams while effectively ensuring the beautiful appearance of the overall frame structure.

[0050] Example 1

[0051] Reference Figure 1and attached Figure 2 The prefabricated frame structure provided by the embodiment of the present disclosure includes a prefabricated frame column 1, a prefabricated frame beam 2 and a filling part (not shown in the figure), wherein the prefabricated frame column 1 is arranged in a vertical direction, and a node area 11 is provided on at least one side surface of the prefabricated frame column 1, and a first connecting component 4 and a second connecting component are provided in the node area 11; the prefabricated frame beam 2 is arranged in a direction corresponding to the node area 11 and meeting the vertical condition with the prefabricated frame column 1, and the end of the prefabricated frame beam 2 extends out of a third connecting component 5 and a fourth connecting component, wherein the third connecting component 5 is used for quickly connecting the first connecting component 4, and the fourth connecting component is used for screwing the second connecting component; if the third connecting component 5 is connected to the first connecting component 4 and the fourth connecting component is screwed to the second connecting component, an assembly gap 3 is formed between the node area 11 and the end of the prefabricated frame beam 2; the filling part is arranged in the assembly gap 3, and is used for wrapping the first connecting component 4, the second connecting component, the third connecting component 5 and the fourth connecting component, and the outer wall of the filling part is flush with the outer wall of the prefabricated frame beam 2.

[0052] The prefabricated frame structure includes a plurality of prefabricated frame columns 1 and a plurality of prefabricated frame beams 2; the prefabricated frame column 1 may be a prismatic structure with a rectangular cross section and extending in the vertical direction, the bottom of which is fixed to a preset position of the construction site, specifically to a foundation or other prefabricated frame structure, and slurry 12 is prefabricated and poured therein. The prefabricated frame column 1 is a longitudinal load-bearing member, which can effectively transfer the weight of the building to the foundation or the ground. The node area 11 is a connection area reserved for the corresponding prefabricated frame beam 2. One or more node areas 11 may be provided on the same prefabricated frame column 1, but not limited to. The node area 11 may be provided at a specified height of the vertical side wall of the prefabricated frame column 1, and may cover the entire width of the prefabricated frame column 1 or only part of the width. The prefabricated frame beam 2 may be a prismatic beam structure with a rectangular cross section and extending in the horizontal direction, the end of which is connected to the prefabricated frame column 1, and plays the role of bearing other components of the prefabricated building and transmitting force laterally, and slurry 12 is prefabricated and poured therein. The prefabricated frame beam 2 in this embodiment is a notched beam, the end opening of which is not completely cast, and the end retains a portion of the side wall around its axial direction to reserve an operating position for the connection of each component. Figure 1 In this embodiment, the end opening of the prefabricated frame beam 2 can be set to have a lower side wall 22, a front side wall 23 and a rear side wall 24, and the dimension of the lower side wall 22 along the axial direction of the prefabricated frame beam 2 is larger than the dimensions of the front side wall 23 and the rear side wall 24 in this direction, so that there is sufficient space at the operating position, which can be used as a template structure for pouring the filling part later.

[0053] In this embodiment, satisfying the vertical condition means being vertical or approximately vertical, and the following satisfying the vertical condition all have the same meaning and will not be described in detail later.

[0054] Among them, the first connecting component 4 and the second connecting component are both rigid structures, and the first connecting component 4 and the second connecting component are both pre-buried in the prefabricated frame column 1, and a connection end is reserved at the node area 11. The pre-buried first connecting component 4 and the second connecting component can be achieved by connecting steel bars 13. For example, the first end of the first connecting component 4 is welded to the connecting steel bar 13 and pre-buried in the prefabricated frame column 1, and the second end of the first connecting component 4 forms a second connecting end outside the node area 11, so that the second connecting end can be stably reserved outside the node area 11 for connection, and the connecting steel bar 13 can be selected Figure 1 The bending form and the through form shown can also be mechanically anchored; the first connecting component 4 and the third connecting component 5 are quickly connected, so that the prefabricated frame beam 2 has a relatively fixed connection point when hoisting, without temporary support, saving time and cost, and avoiding the shaking of the prefabricated frame beam 2 during the hoisting process, increasing the difficulty of screw connection and even affecting the stability of screw connection. The third connecting component 5 and the fourth connecting component are also rigid structures. The third connecting component 5 and the fourth connecting component are both pre-buried in the prefabricated frame beam 2, and the connecting end is extended at the end opening to cooperate with the first connecting component 4 and the second connecting component, that is, corresponding to the above content, the first end of the third connecting component 5 is pre-buried in the prefabricated frame beam 2, and the second end of the third connecting component 5 is extended at the end opening of the prefabricated frame beam 2 to form a third connecting end. In this embodiment, the second connecting end and the third connecting end can be hinged to each other, overlapped with each other, screwed to each other, or clamped to each other, so as to quickly form a positioning connection point when the prefabricated frame column 1 and the prefabricated frame beam 2 are initially connected, stabilize the prefabricated frame beam 2, and ensure the stability of subsequent screw connection. The second connection assembly and the fourth connection assembly may be a combination of a bolt and a threaded sleeve.

[0055] Specifically, in order to simplify the structure in this embodiment, refer to the attached Figure 3 , Attachment Figure 4 and attached Figure 5, the second connecting end includes a first plate body 41 and a second plate body 42; the first plate body 41 is attached to the node area 11, specifically welded to the connecting steel bar 13, the second plate body 42 is perpendicular to the first plate body 41, and the second plate body 42 is provided with a first opening; the third connecting assembly 5 includes a third plate body 51, the third plate body 51 is provided with a second opening adapted to the first opening, and the two sides of the third plate body 51 are respectively provided with a plurality of connecting anchor rods 52 perpendicular to the third plate body 51, at least part of the connecting anchor rods 52 are embedded in the prefabricated frame beam 2; if the second plate body 42 and the third plate body 51 are attached, the second plate body 42 and the third plate body 51 can be connected through the first opening and the second opening that are opposite and connected to each other and are matched with pins or bolts. It can be understood that the second plate body 42 can be Figure 5 The second plate 42 may be vertically arranged or horizontally arranged. When the second plate 42 is vertically arranged, the insertion direction of the first opening thereon is horizontal, and accordingly, the third plate 51 is also vertically arranged, and the insertion direction of the second opening is also horizontal; when the second plate 42 is horizontally arranged, the insertion direction of the first opening thereon is vertical, and accordingly, the third plate 51 is also horizontally arranged, and the insertion direction of the second opening is also vertical. When the second plate 42 is horizontal, it may not be provided with the first opening, so as to support the third plate 51 in the up-down direction. When the second plate 42 is vertical, the third connecting assembly 5 may also include a fourth plate (not shown) parallel to and spaced from the third plate 51, and the fourth plate is provided with a third opening coaxial with the second opening, and the second plate 42 is clamped between the third plate 51 and the fourth plate, and then a pin or bolt is inserted to connect them.

[0056] Among them, when connecting each connection component through the end opening of the prefabricated frame beam 2, it is necessary to use the end opening to form an operating position, and then after each connection component is connected, an assembly gap 3 will be formed between the prefabricated frame column 1 and the prefabricated frame beam 2. There is no appearance part at the assembly gap 3, and the connection of each connection component is exposed. Then, in this embodiment, a filling part is set to fill the assembly gap 3, and at the same time, each connection component is wrapped, which beautifies and completes the external visual effect, and can also enhance the integrated connection of the assembled frame structure. The filling part can be a slurry 12 of the same material as the cast inside the prefabricated frame column 1 and the prefabricated frame beam 2. In this embodiment, the lower side wall 22 and the relevant side template can be used to cooperate to surround the assembly gap 3 to form a filling space, and then pour, fill, and demold inward. The setting of the filling part allows each connection component to be wrapped, thereby avoiding the need for anti-corrosion and fireproofing treatment of each connection component, effectively reducing the process and cost.

[0057] According to the above, the prefabricated frame structure provided by the present invention realizes the connection between the prefabricated frame beam 2 and the prefabricated frame column 1 through the connection cooperation of the first connecting component 4 and the third connecting component 5, and the screw connection cooperation of the second connecting component and the fourth connecting component, thereby avoiding on-site wet work, being quick and efficient, and at the same time using the filling part to fill the assembly gap 3 formed in the process of connecting each connecting component, so that all the connecting components can be wrapped, avoiding the leakage of the connecting components affecting the appearance of the overall frame structure; thereby solving the problem of the prior art of prefabricated concrete frame connection, in which the corbel leaks, affecting the structural appearance and limiting the application.

[0058] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B, which is specifically understood as: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may exist.

[0059] Further, see Attachment Figure 2 and attached Figure 3 In the assembled frame structure provided in this embodiment, in a specific implementation, the second connecting component includes a first screw terminal 6 and a second screw terminal 7, and the first screw terminal 6 and the second screw terminal 7 are respectively located on both sides of the first connecting component 4 in the vertical direction; the fourth connecting component includes a first connecting box 8 and a second connecting box 9, and the first connecting box 8 and the second connecting box 9 are respectively located on both sides of the third connecting component 5 in the vertical direction, so as to correspond to and be screwed to the first screw terminal 6 and the second screw terminal 7 respectively.

[0060] It can be understood that in order to realize the screw connection between the second connecting component and the fourth connecting component and ensure stable connection and efficient force transmission, in this embodiment, the first screw connection end 6 and the second screw connection end 7 are respectively arranged on the upper and lower parts of the first connecting component 4, and the corresponding first connection box 8 and the second connection box 9 are respectively arranged on the upper and lower parts of the third connecting component 5, so as to stably connect and support the prefabricated frame beam 2 in the direction of gravity; the first screw connection end 6 and the second screw connection end 7 can be symmetrically arranged relative to the first connecting component 4, or the first screw connection end 6, the first connecting component 4, and the second screw connection end 7 can be staggered in the vertical direction, and the first connection box 8 and the second connection box 9 can be arranged in the same corresponding manner. The first screw connection end 6 and the second screw connection end 7 can be bolt holes or bolt columns, and the corresponding first connection box 8 and the second connection box 9 can provide bolt columns or bolt holes, and the first connection box 8 and the second connection box 9 can be open boxes or groove boxes.

[0061] Further, see Attachment Figure 2 and attached Figure 3In the assembled frame structure provided in this embodiment, in a specific implementation, the first threaded end 6 and the second threaded end 7 have the same structure, and both include at least two threaded sleeves 61; at least two of the threaded sleeves 61 are pre-buried in the prefabricated frame column 1 at intervals along a first direction a and expose a threaded opening in the node area 11; wherein the first direction a satisfies the vertical condition at the same time with the extension direction of the prefabricated frame column 1 and the extension direction of the prefabricated frame beam 2.

[0062] It is understandable that in order to simplify the connection and improve the efficiency, in this embodiment, the first screw connection end 6 and the second screw connection end 7 are set in the form of a bolt hole, so that when the connection is made, the bolt monomer can be screwed at the opening of the prefabricated frame beam 2, rather than the bolt hole and the entire carrier, which reduces the difficulty of operation. In this embodiment, the screw connection end is set to include at least two screw connection sleeves 61 along the first direction a, and the first direction a is the width direction of the prefabricated frame beam 2 and the prefabricated frame column 1 in the actual installation. The number of screw connection sleeves 61 and the distance between adjacent screw connection sleeves 61 in the first direction a can be adjusted according to the size design of the prefabricated frame beam 2 to ensure the connection strength in the width direction of the prefabricated frame beam 2. It is understandable that the first connection box 8 and the second connection box 9 need to extend the connection bolt. The screw connection sleeve 61 is embedded in the prefabricated frame column 1 through the connecting steel bar 13, and the screw connection opening is reserved in the node area 11 to ensure the connection strength and appearance.

[0063] Further, see Attachment Figure 2 and attached Figure 4 In the assembled frame structure provided in this embodiment, in a specific implementation, the first connection box 8 and the second connection box 9 have the same structure and both include a box body 81; the two ends of the box body 81 are respectively provided with a third screw end 82 and a first connection end 83, the third screw end 82 is used to adapt to the screw connection of the first screw end 6 or the second screw end 7, the first connection end 83 is used for welding and connecting the longitudinal steel bars 25 in the prefabricated frame beam 2, and the first connection end 83 is pre-embedded in the prefabricated frame beam 2.

[0064] It can be understood that in order to cooperate with the first threaded end 6 and the second threaded end 7 and reduce the difficulty of design and installation, in this embodiment, the first connecting box 8 and the second connecting box 9 are set to the same structure, and the first connecting box 8 and the second connecting box 9 are provided with a third threaded end 82 and a first connecting end 83. It is not difficult to understand that the third threaded end 82 includes a number of bolts corresponding to the threaded sleeve 61, and the first connecting end 83 can be rod-shaped, plate-shaped, block-shaped, etc., as long as it can be welded with the longitudinal steel bars 25 of the prefabricated frame beam 2 and embedded in the prefabricated frame beam 2, so as to ensure the embedded strength of the first connecting box 8 and the second connecting box 9.

[0065] Further, see Attachment Figure 2 and attached Figure 6 In the assembled frame structure provided in this embodiment, in a specific implementation, the box body 81 includes a bottom plate 811, a first side plate 812, a second side plate 813 and a reinforcing plate 814; the bottom plate 811 is parallel to the inner wall of the side wall of the prefabricated frame beam 2, and the first side plate 812 and the second side plate 813 extend from the two ends of the bottom plate 811 to the first side of the inner wall of the prefabricated frame beam 2; the reinforcing plate 814 is perpendicular to the bottom plate 811 on the first side of the bottom plate 811 and simultaneously connects the bottom plate 811, the first side plate 812 and the second side plate 813; the third screw end 82 can movably pass through the first side plate 812 and extend in a direction away from the second side plate 813; the first connecting end 83 passes through the second side plate 813 and extends in a direction away from the first side plate 812.

[0066] It can be understood that the third screw connection end 82 and the first connection end 83 are arranged on the box body 81 back to back, and the third screw connection end 82 needs to be movable. In order to achieve stable cooperation between the box body 81 and the third screw connection end 82 and the first connection end 83, in this embodiment, the box body 82 is arranged as a U-shaped groove structure surrounded by a bottom plate 811, a first side plate 812 and a second side plate 813. The bottom plate 811, the first side plate 812 and the second side plate 813 are all rigid plates, which can be straight plates or bent plates, and can be designed and adjusted according to actual needs; in this embodiment, the first side plate 812 and the second side plate 813 are respectively used as the setting carriers of the third screw connection end 82 and the first connection end 83. In this embodiment, the bottom plates 811 of the two box bodies are close to each other And the openings are opposite to each other, so that the third screwed end 82 can be exposed at the upper and lower openings of the prefabricated frame beam 2, which is easy to operate; at the same time, in order to ensure the strength of the box body 81 and avoid the third screwed end 82 being subjected to force to cause deformation of the box body 82 after the first connection end 83 is embedded, a reinforcement plate 814 is provided in this embodiment. The reinforcement plate 814 is a rigid plate body, which can be a straight plate body or a bent plate body. It is connected to the bottom plate 811, the first side plate 812 and the second side plate 813 on the first side of the bottom plate 811 at the same time, serving as a force transmission structure between the first side plate 812 and the second side plate 813. The reinforcement plate 814 can be set corresponding to the center line of the bottom plate 811 in the first direction a to ensure that the third screwed end 82 is connected and the force is uniform when corresponding to the two screwed sleeves 61.

[0067] Further, see Attachment Figure 4 and attached Figure 6, this embodiment provides an assembled frame structure. In a specific implementation, the third screw connection end 82 includes at least two bolts 821; at least two of the bolts 821 are respectively located on both sides of the reinforcing plate 814, and the bolt 821 is located on the side of the first side plate 812 facing the second side plate 813 and is provided with a first nut 822, and the bolt 821 is located on the side of the first side plate 812 facing away from the second side plate 813 and is sequentially provided with a gasket 823 and a second nut 824;

[0068] The first connecting end 83 includes at least two connecting rods 831; at least two connecting rods 831 are respectively located on both sides of the reinforcing plate 814, and the connecting rods 831 are respectively welded with a longitudinal steel bar 25 on both sides along the second direction, and the second direction satisfies the vertical condition with the extension direction of the prefabricated frame column 1 and the extension direction of the prefabricated frame beam 2 at the same time; the connecting rod 831 is the bolt.

[0069] It is understandable that, in order to match the threaded sleeve 61, the third threaded end 82 is configured to include at least two bolts 821 in this embodiment, and the number and spacing of the bolts 821 are compatible with the bolt sleeve 62, which will not be described in detail here; when installed with the bolt sleeve 61, the bolt 821 is screwed into the bolt sleeve 61, and the first nut 822 and the second nut 824 are tightened. Of course, a gasket 823 can also be set on the side of the first nut 822. This setting can be easily understood by those skilled in the art, and will not be described in detail here. The second direction here is the same as the first direction a mentioned above or on the same straight line, which will not be described in detail here. In this embodiment, the first connecting end 83 is set in the form of a connecting rod 831, which is convenient for welding the longitudinal steel bar 25. The connecting rod 831 and the second side plate 813 can also be welded and screwed. The connecting rod 831 can be a bolt or a steel bar. At the same time, in order to simplify the structure of the first connecting box 8 and the second connecting box 9 and reduce the difficulty of design and molding, in this embodiment, the connecting rod 831 can be set as a bolt 821 that is the same as the third screw end 82, so that the first connecting box 8 and the second connecting box 9 do not need to consider the directionality during installation. The third screw end 82 and the first connecting end 83 are both bolts, which can be interchanged and directly installed, thereby reducing the difficulty and precision requirements of installation.

[0070] Further, see Attachment Figure 2 and attached Figure 4, this embodiment provides an assembled frame structure, in which, in a specific implementation, a plurality of longitudinal steel bars 25 and a plurality of stirrups 26 are provided in the prefabricated frame beam 2; the plurality of longitudinal steel bars 25 are spaced around the axial direction of the prefabricated frame beam 2 and extend along the axial direction of the prefabricated frame beam 2; the plurality of stirrups 26 are spaced along the axial direction of the prefabricated frame beam 2, and the stirrups 26 surround the plurality of longitudinal steel bars 25 and contact the longitudinal steel bars 25; the longitudinal steel bar 25 has a first bending section 27 and a second bending section 21 at one end facing the fourth connecting assembly, and the first bending section 27 and the second bending section 21 are sequentially connected in a direction away from the longitudinal steel bar 25; the first bending section 27 is inclined from the longitudinal steel bar 25 toward the axial direction of the prefabricated frame beam 2, so that the second bending section 21 is flush with at least a portion of the connecting rod 831; the connecting rod 831 and the second bending section 21 both contact the stirrups 26.

[0071] It can be understood that the longitudinal reinforcement 25 is a longitudinal reinforcement extending along the axial direction of the prefabricated frame beam 2 and arranged around the axial direction of the prefabricated frame beam 2 to improve the bending bearing capacity of the beam. The number of longitudinal reinforcements 25 can be designed and adjusted according to actual needs, for example, Figure 4 As shown, four stirrups 26 are arranged in the width direction of the prefabricated frame beam 2; stirrups 26 are steel bars that surround the outer ring of the longitudinal steel bars 25 inside the prefabricated frame beam 2 to impose circumferential constraints on the longitudinal beam and strengthen the strength and rigidity of the prefabricated frame beam 2. In this embodiment, the connecting rod 831 needs to pass through the second side plate 823, so that there will be a gap between the connecting rod 831 and the upper side wall and the lower side wall 22 of the prefabricated frame beam 2, and then there will be a gap between the connecting rod 831 and the longitudinal steel bars 25 in the radial direction of the prefabricated frame beam 2, and the two cannot be welded. In this embodiment, the second bending section 21 is guided to a position flush with the connecting rod 831 by the inclined setting of the first bending section 27. The second bending section 21 is a steel bar structure that is arranged straight along the axial direction of the prefabricated frame beam 2, so as to facilitate mutual fitting and welding with the connecting rod 831. In this embodiment, the diameter of the connecting rod 831 is greater than the diameter of the longitudinal steel bars 25, thereby effectively ensuring the connection strength of the first connecting end 83 and reducing the welding difficulty and precision requirements of the connecting rod 831 and the longitudinal steel bars 25. In this embodiment, the upper wall of the connecting rod 831 in the first connecting box 8 is flush with the upper wall of the longitudinal steel bar 25 and contacts the inner wall of the stirrup 26, and the lower wall of the connecting rod 831 in the second connecting box 9 is flush with the lower wall of the longitudinal steel bar 25 and contacts the inner wall of the stirrup 26, thereby ensuring the stable binding of the stirrup 26. At the same time, in order to ensure the strength of the prefabricated frame beam 2 at the first bending section 27, refer to the attached Figure 6In this embodiment, the tangent value of the angle β between the first bending section 27 and the second bending section 21 is set to be less than or equal to 1 / 6, thereby avoiding the inclination angle of the first bending section 27 being too large, which causes the steel bar support strength between the first bending section 27 and the side wall of the prefabricated frame beam 2 to decrease.

Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
