The connecting plate is fixedly connected with a main reinforcement in the column body; a supporting block is fixedly installed on the connecting column, and a butt joint hole corresponding to the connecting column is formed in the connecting plate. A frustum is fixedly mounted on the connecting column, and a butt joint column is fixedly mounted on the frustum; the supporting block is provided with a limiting structure, and the limiting structure can limit the connecting plate when the connecting plate is completely attached to the supporting block. When the connecting plate is completely attached to the supporting block, the limiting structure can act in time to limit the connecting plate, due to the fact that the weight of the column body is large, and the length of the part, penetrating through the butt joint hole, of the connecting column is large, the limiting structure only needs to limit the connecting plate so as to further prevent the connecting plate from being separated from the prefabricated foundation. And the capability of the connection node for coping with accidental situations can be improved.

Description

Technical Field

[0001] The utility model relates to a connection node, in particular to a connection node between a prefabricated foundation and a fully assembled building body. Background Art

[0002] Fully prefabricated buildings are structures assembled on-site from prefabricated components. This construction method shifts much of the on-site work involved in traditional construction methods to the factory. Building components and accessories (prefabricated foundations, columns, beams, slabs, etc.) are manufactured in the factory and then transported to the construction site for assembly and installation using reliable connections.

[0003] The precast foundation is responsible for bearing the overall weight of the building; the main structure (including columns, beams, slabs, etc.) is responsible for supporting and transferring loads. During the construction of precast components, the quality of the connection nodes between the various structures is particularly important, as it determines the stability and strength of the entire prefabricated building. For example, if the connection strength between the precast foundation and the column is not high, the column will deform and move under the load on the precast foundation, greatly affecting the quality of the building. The connection nodes between the precast foundation and the column are commonly connected using bolts.

[0004] When the connection nodes between the prefabricated foundation and the column are connected by bolts, it is necessary to connect the connection plate (with multiple connection holes) installed on the column with the connection rod buried in the foundation (by hoisting method), and then reinforce it with bolts. Since the diameter of the connection rod on the connection node of the common bolt connection is basically the same as the hole diameter of the connection hole on the installation plate, it is very difficult to connect all the connection holes with the connection rod, which greatly increases the construction time and construction cost. Utility Model Content

[0005] The purpose of the present invention is to provide a connection node between a prefabricated foundation and a fully assembled building body, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A connection node between a prefabricated foundation and a fully assembled building body, comprising a plurality of connection columns embedded in the prefabricated foundation; and a connection plate fixedly connected to the main reinforcement in the column;

[0008] A support block for supporting the connecting plate and the column is fixedly mounted on the connecting column, and a docking hole corresponding to the connecting column is opened on the connecting plate;

[0009] The connecting column is fixedly mounted with a frustum, and the frustum is fixedly mounted with a docking column;

[0010] A limiting structure is provided on the support block, and the limiting structure can limit the connection plate when the connection plate is completely fitted with the support block.

[0011] The connection node between the prefabricated foundation and the fully assembled building body as described above: the diameter of the docking column is smaller than the diameter of the docking hole, and the diameter of one circular surface of the frustum is the same as that of the docking column, and the diameter of the other circular surface is the same as that of the connecting column, and the diameter of the connecting column is slightly smaller than the diameter of the docking hole.

[0012] The connection node between the prefabricated foundation and the fully assembled building body as described above: the diameter of the support block is larger than the diameter of the connecting column and larger than the diameter of the docking hole, and the contact surfaces of multiple support blocks and the connecting plate are located on the same plane.

[0013] The connection node between the prefabricated foundation and the fully assembled building body as described above: the limiting structure includes a first slide groove provided on the support block, and a second slide groove provided on the support block and the connecting column, the first slide groove is connected to the second slide groove, a pressing block is slidably engaged in the first slide groove, a first wedge block is fixedly installed on the pressing block, a transmission block is slidably engaged in the second slide groove, a transmission groove is provided on the transmission block, and a return spring fixedly connected to the connecting column is fixedly installed on the transmission block.

[0014] The connection node between the prefabricated foundation and the fully assembled building body as described above: the limiting structure also includes a third slide groove provided on the connecting column, the third slide groove is connected to the second slide groove, and the connecting column is also provided with a fourth slide groove connected to the third slide groove, a locking block that cooperates with the transmission groove is slidably engaged in the third slide groove, a second wedge block is fixedly installed on the locking block, and a locking block is slidably engaged in the fourth slide groove, the locking block is provided with a locking groove that cooperates with the second wedge block, and a locking spring fixedly connected to the connecting column is fixedly installed on the locking block.

[0015] As described above, the connection node between the prefabricated foundation and the fully assembled building body: the surface where the first wedge block cooperates with the transmission block is a sloped surface, the surface where the transmission groove cooperates with the locking block is an inclined surface, and the surface where the locking groove cooperates with the locking block is a straight surface.

[0016] The connection node between the prefabricated foundation and the fully assembled building body as described above: the distance between the locking block and the supporting block is slightly greater than the thickness of the connecting plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the diameter of the docking column is smaller than the diameter of the docking hole, so there is a large displacement space (adjusting the position of the docking column in the docking hole) during the docking process between the docking column and the docking hole. This space is conducive to multiple docking columns passing through the docking hole, thereby reducing the difficulty of docking and effectively shortening the construction time; during the hoisting process, the inclined surface of the cone will contact the docking hole, and then the inclined surface will act on the wall of the docking hole to correct the position of the connecting plate (the center of the docking hole and the center of the connecting column are located on the same vertical axis), thereby improving the accuracy of the connection and thus improving the quality of the project; when the connecting plate and the support block are fully fitted, the limiting structure will act in time to limit the connecting plate. Since the weight of the column is large and the length of the part of the connecting column passing through the docking hole is long, the limiting structure only needs to limit the connecting plate to further prevent the connecting plate from separating from the prefabricated foundation, and can improve the ability of the connection node to cope with accidental situations (such as the up and down shaking of the column caused by earthquake waves).

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] See also Figures 1 to 9 As an embodiment of the present invention, the connection node between the prefabricated foundation and the fully assembled building body includes a plurality of connection columns 1 embedded in the prefabricated foundation 10; and a connection plate 3 fixedly connected to the main reinforcement 1101 in the column 11;

[0040] The connecting column 1 is fixedly mounted with a support block 2 for supporting the connecting plate 3 and the column 11. The connecting plate 3 is provided with a docking hole 301 corresponding to the connecting column 1.

[0041] The connecting column 1 is fixedly mounted with a frustum 102, and the frustum 102 is fixedly mounted with a docking column 101;

[0042] A limiting structure is provided on the support block 2 , and the limiting structure can limit the connection plate 3 when the connection plate 3 is completely fitted with the support block 2 .

[0043] In this embodiment, after the prefabricated foundation 10 is fixedly connected to the piles buried underground, a hoisting mechanism is used to lift the columns 11 on the fully assembled building body to just above the prefabricated foundation 10, and then docking begins.

[0044] During docking, align the docking holes 301 with the docking columns 101 one by one, and then slowly hoist the column 11 so that the connecting plate 3 is completely fitted with the support block 2. During the hoisting process, the cone 102 will correct the position of the connecting plate 3 so that the center of the docking hole 301 is concentric with the center of the connecting column 1, thereby improving the stability of the connection between the prefabricated foundation 10 and the column 11.

[0045] When the connecting plate 3 is completely fitted with the supporting block 2, the limiting structure will act in time to limit the connecting plate 3. Since the weight of the column 11 is large and the length of the portion of the connecting column 1 passing through the docking hole 301 is long, the limiting structure only needs to limit the connecting plate 3 to further prevent the connecting plate 3 from separating from the prefabricated foundation 10, and can improve the ability of the connection node to cope with accidental situations (such as the up and down shaking of the column 11 caused by earthquake waves, etc.); after the connection is completed, the connection node is further reinforced by post-pouring concrete to improve stability.

[0046] As a further solution of the present invention, the diameter of the docking column 101 is smaller than the diameter of the docking hole 301, and the diameter of one circular surface of the frustum 102 is the same as that of the docking column 101, and the diameter of the other circular surface is the same as that of the connecting column 1, and the diameter of the connecting column 1 is slightly smaller than the diameter of the docking hole 301.

[0047] In this embodiment, since the diameter of the docking column 101 is smaller than the diameter of the docking hole 301, there is a large displacement space (adjusting the position of the docking column 101 in the docking hole 301) during the docking process between the docking column 101 and the docking hole 301. This space is conducive to multiple docking columns 101 passing through the docking hole 301, thereby reducing the difficulty of docking and effectively shortening the construction time.

[0048] During the hoisting process, the inclined surface of the cone 102 will contact the docking hole 301, and then the inclined surface will act on the wall of the docking hole 301 to correct the position of the connecting plate 3 (the center of the docking hole 301 and the center of the connecting column 1 are located on the same vertical axis), thereby improving the accuracy of the connection and thus improving the quality of the project.

[0049] As a further solution of the present invention, the diameter of the support block 2 is larger than the diameter of the connecting column 1 and larger than the aperture of the docking hole 301, and the surfaces of the support blocks 2 in contact with the connecting plate 3 are located on the same plane.

[0050] In this embodiment, the surfaces where the multiple support blocks 2 contact the connecting plate 3 are located on the same horizontal plane, which can ensure the verticality of the column 11, thereby improving the quality of the project and avoiding the possibility of overturning; the diameter of the support block 2 determines the reliability of the support (the larger the diameter, the larger the contact area with the connecting plate 3, which can better support the connecting plate 3), avoiding the possibility of collapse.

[0051] As a further solution of the present invention, the limiting structure includes a first slide groove 201 provided on the support block 2, and a second slide groove 202 provided on the support block 2 and the connecting column 1. The first slide groove 201 is connected to the second slide groove 202. A pressing block 4 is slidably engaged in the first slide groove 201, and a first wedge block 401 is fixedly installed on the pressing block 4. A transmission block 5 is slidably engaged in the second slide groove 202. A transmission groove 501 is provided on the transmission block 5, and a return spring 6 fixedly connected to the connecting column 1 is fixedly installed on the transmission block 5.

[0052] As a further solution of the present invention, the limiting structure also includes a third slide groove 203 provided on the connecting column 1, and the third slide groove 203 is connected to the second slide groove 202. The connecting column 1 is also provided with a fourth slide groove 204 connected to the third slide groove 203, and a locking block 7 that cooperates with the transmission groove 501 is slidably engaged in the third slide groove 203, and a second wedge block 701 is fixedly installed on the locking block 7, and a locking block 8 is slidably engaged in the fourth slide groove 204, and a locking groove 801 that cooperates with the second wedge block 701 is provided on the locking block 8, and a locking spring 9 fixedly connected to the connecting column 1 is fixedly installed on the locking block 8.

[0053] As a further solution of the present invention, the surface where the first wedge block 401 cooperates with the transmission block 5 is a sloped surface, the surface where the transmission groove 501 cooperates with the locking block 7 is an inclined surface, and the surface where the locking groove 801 cooperates with the locking block 7 is a straight surface.

[0054] When the cam 711 is in the locked state, the locking cam 701 is in the locked state, and the locking cam 701 is in the locked state.

[0055] During the process of hoisting the column 11, the connecting plate 3 will first contact the pressing block 4 and drive the pressing block 4 to slide inward in the first slide groove 201. During the sliding process, the slope of the first wedge block 401 will squeeze the transmission block 5, causing the transmission block 5 to slide from the first slide groove 201 to the second slide groove 202, compressing the return spring 6. During the sliding process of the transmission block 5, the position of the transmission groove 501 changes. At this time, the locking block 7 will slide along the inclined surface of the transmission groove 501 in the direction of gravity under the action of gravity, so that the contact area between the second wedge block 701 and the engaging block 8 gradually decreases.

[0056] When the connecting plate 3 is completely in contact with the supporting block 2, the pressing block 4 will be completely immersed in the first slide groove 201, so that the transmission block 5 is squeezed into the second slide groove 202. At this time, the locking block 7 drives the second wedge block 701 to drop to a position completely separated from the locking groove 801. Under the elastic force of the locking spring 9, the locking block 8 will extend outward in the fourth slide groove 204 to limit the connecting plate 3. That is, when the connecting plate 3 is completely in contact with the supporting block 2, the limiting structure will act in time to limit the connecting plate 3. Since the weight of the column 11 is large and the length of the part of the connecting column 1 passing through the docking hole 301 is long, the limiting structure only needs to limit the connecting plate 3 to further prevent the connecting plate 3 from separating from the precast foundation 10, and can improve the ability of the connection node to cope with accidental situations (such as the up and down shaking of the column 11 caused by earthquake waves, etc.); after the connection is completed, the connection node is further reinforced by post-pouring concrete to improve stability.

[0057] As a further solution of the present invention, the distance between the engaging block 8 and the supporting block 2 is slightly greater than the thickness of the connecting plate 3 .

[0058] In this embodiment, when the spacing of the snap blocks 8 is less than or equal to the thickness of the connecting plate 3, the inner wall of the docking hole 301 will limit the snap blocks 8 from popping out, thereby affecting the limiting effect of the limiting structure on the connecting plate 3. When the spacing of the snap blocks 8 is greater than the thickness of the connecting plate 3, there is no contact between the snap blocks 8 and the connecting plate 3, which also affects the limiting effect of the limiting structure on the connecting plate 3.

[0059] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
