[0030] 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.

[0031] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] Embodiment 1:

[0033] Reference Figure 1-Figure 9 , a building node structure of an assembled composite slab and a supporting member, comprising a supporting beam 1 and a concrete slab 2 perpendicular to the supporting beam 1, the concrete slab 2 being used for laying and installing on the top of the supporting beam 1, and also comprising: a plurality of rectangular frames 3 arranged at equal intervals, all of which are fixedly connected in the concrete slab 2, the rectangular frames 3 are welded by a combination of threaded steel bars, and are used to ensure the service strength of the concrete slab 2, the number of rectangular frames 3 is 3-10, and the preferred number in this application is 3, wherein the top of the rectangular frame 3 is fixedly connected with a plurality of upper cross bars 4 arranged at equal intervals, and the bottom of the rectangular frame 3 is fixedly connected with a plurality of lower cross bars 5 arranged at equal intervals, the number of the upper cross bars 4 and the lower cross bars 5 is the same, both of which are 5-12, and the preferred number in this application is 5, the upper cross bars 4 and the lower cross bars 5 are both threaded steel bars, which are welded to the rectangular frame 3 or tied together by steel wire ropes; a plurality of pillars 6 arranged at equal intervals, the number of the pillars 6 is the same as the number of the upper cross bars 4, and are all fixedly connected in the supporting beam 1, wherein the lower cross bars 5 and the pillars 6 are connected by buckling parts.

[0034] Specifically, when in use, the concrete slab 2 is hoisted downward until one end of the concrete slab 2 is placed on the top of the support beam 1, and then the lower horizontal bar 5 is connected to the support 6 through the buckle part, so that the concrete slab 2 and the support beam 1 can be connected together, thereby reducing the laying amount of support parts under the concrete slab 2 and improving the installation efficiency.

[0035] Both sides of the rectangular frame 3 are fixedly connected with T-shaped rods 26 extending to the outer wall of the concrete slab 2. When multiple concrete slabs 2 are installed side by side, there will be two symmetrically arranged T-shaped rods 26 in the gap between adjacent concrete slabs 2. At this time, concrete is poured into the gap, and the two symmetrically arranged T-shaped rods 26 can enhance the connection strength between the two concrete slabs 2.

[0036] A lifting ring 18 for lifting the concrete slab 2 is fixedly connected to the top of the rectangular frame 3 , and the lifting ring 18 has a triangular shape.

[0037] Embodiment 2:

[0038] Reference Figure 2-Figure 7 , which is basically the same as the first embodiment, and further discloses a specific implementation scheme of the buckle part.

[0039] The above-mentioned buckling part includes a horizontal column 7 fixedly connected to the top of the pillar 6, and both ends of the lower horizontal bar 5 are fixedly connected with diagonal rods 9. The horizontal column 7, the diagonal rods 9 and the pillar 6 are made of the same material, namely threaded steel, and the ends of the two diagonal rods 9 are fixedly connected with an integrally formed main hook 8. During installation, the main hook 8 is buckled on the outer wall of the horizontal column 7, wherein both sides of the pillar 6 are fixedly connected with diagonal columns 10, and the material of the diagonal columns 10 is also threaded steel. The angle between the diagonal columns 10 and the pillar 6 is 30°-60°, and the preferred angle of this application is 30°. The top of the diagonal column 10 is pressed against the lower end of the lower horizontal bar 5, and grooves 16 are provided on both sides of the upper end of the support beam 1, and bosses 17 are provided on both sides of the lower end of the concrete slab 2 and are sleeved in the grooves 16.

[0040] Specifically, when in use, the concrete slab 2 is hoisted downward, and the boss 17 at one end is placed in the groove 16 of the support beam 1, and the main hook 8 close to the horizontal column 7 is buckled on the horizontal column 7. At the same time, the top of the inclined column 10 is against the lower end of the lower horizontal bar 5. At this time, the support column 6, the inclined column 10 and the lower horizontal bar 5 will be combined into a tripod for supporting the concrete slab 2. Then the hoisting device for hoisting the concrete slab 2 is released, and the concrete slab 2 will be effectively supported, which can effectively reduce the laying work of the support parts. Then, concrete is poured on the top of the support beam 1 and completely submerges the main hook 8, the horizontal column 7, the left hook 12 or the main hook 8. When the poured concrete solidifies, the tripod composed of the support column 6, the inclined column 10 and the lower horizontal bar 5 can also improve the stability of the concrete slab 2 and the seismic performance, and the whole installation process is relatively simple.

[0041] Of course, during installation, a support frame for supporting the concrete slab 2 can be laid as needed, which depends on the total weight of the concrete slab 2. When the total weight of the concrete slab 2 is greater than the supporting strength of the tripod, a support member needs to be erected.

[0042] The two ends of the upper horizontal bar 4 are respectively fixedly connected with a left hook 12 and a right hook 13 , the opening of the left hook 12 is set downward, and the right hook 13 is perpendicular to the left hook 12 , and the left hook 12 and the right hook 13 are integrally formed with the upper horizontal bar 4 .

[0043] Specifically, when concrete slabs 2 are installed on both sides of the upper end of the support beam 1, the concrete slab 2 on one side is installed first, and then the other concrete slab 2 is installed and hoisted. When hoisting, the left hook 12 at the adjacent position is buckled on the right hook 13, so that the two concrete slabs 2 are connected by the left hook 12 and the right hook 13 that are buckled with each other. The weight of the two concrete slabs 2 can be balanced with each other, which can significantly improve the stability of the concrete slab 2 when installed on the support beam 1, and at the same time can further reduce the laying work of the support members.

[0044] The above-mentioned lower horizontal bar 5 is provided with a lower curved portion 11 that is curved upward, and the lower end of the concrete slab 2 is provided with an inclined hole 25 that extends to the lower curved portion 11. The end of the inclined column 10 passes through the inclined hole 25 and rests on the lower curved portion 11; therefore, during installation, the end of the inclined column 10 is passed through the inclined hole 25 and then rests on the lower curved portion 11, which can improve the supporting strength between the inclined column 10 and the lower horizontal bar 5.

[0045] Embodiment three:

[0046] Reference Figure 3 , which is basically the same as the second embodiment, and further, a specific implementation scheme for improving the connection strength between the support beam 1 and the concrete slab 2 is specifically added.

[0047] The top of the support beam 1 is provided with a strip groove 14 , and the top of the support beam 1 is provided with a slot 15 connected to the strip groove 14 . The slot 15 is aligned with the lower horizontal bar 5 and the upper horizontal bar 4 , and the horizontal column 7 is arranged in the strip groove 14 .

[0048] Specifically, when installing the concrete slab 2, the two ends of the upper horizontal bar 4 and the lower horizontal bar 5 need to be passed through the slot 15 and then extended into the strip groove 14. Then, when pouring concrete, the concrete is injected into the strip groove 14. The strip groove 14 can effectively support the poured concrete and ensure the combination effect of the concrete with the lower horizontal bar 5 and the upper horizontal bar 4.

[0049] The bottom of the above-mentioned strip groove 14 is provided with symmetrically arranged inclined grooves 24, and the two inclined grooves 24 are combined with the strip groove 14 to form an inverted Y-shaped groove, and the inclined column 10 passes through the inclined groove 24; after the concrete is injected into the strip groove 14, the shape of the solidified concrete will be an inverted Y shape, which can improve the connection strength between the concrete block and the support beam 1 and the concrete slab 2.

[0050] Embodiment 4:

[0051] Reference Figure 1 , Figure 2 , Figure 4 as well as Fig. 9 , which is basically the same as the third embodiment, and further, a specific implementation scheme for improving the connection strength between the concrete slabs 2 is specifically added.

[0052] A top plate 19 is provided on the top of the support beam 1, and vertical plates 20 are fixedly connected on both sides of the lower end of the top plate 19. L-shaped grooves 21 cooperating with the vertical plates 20 and the top plate 19 are provided on both sides of the concrete slab 2. A plurality of filling grooves 22 arranged at equal intervals are provided on the top of the top plate 19. The number of the filling grooves 22 is the same as the number of the pillars 6, and the filling grooves 22 face the tops of the pillars 6.

[0053] Specifically, after installing the two concrete slabs 2, the top plate 19 and the vertical plate 20 are buckled in the L-shaped grooves 21 of the two concrete slabs 2. At this time, the two concrete slabs 2 will also be limited by the top plate 19, thereby further improving the installation stability of the concrete slabs 2. The filling groove 22 makes it easier for workers to pour concrete into the strip groove 14.

[0054] The upper horizontal bar 4 is provided with an upper curved portion 23 in a curved state, and the upper curved portion 23 corresponds to the position of the L-shaped groove 21; thus, the upper horizontal bar 4 can improve the supporting strength of the L-shaped groove 21 to prevent the L-shaped groove 21 from being damaged due to excessive force.

[0055] When the present assembled composite slab and the building node structure of the supporting member are used, the concrete slab 2 is hoisted downward, and the boss 17 at one end thereof is placed in the groove 16 of the supporting beam 1, and the main hook 8 close to the horizontal column 7 is buckled on the horizontal column 7. At the same time, the top of the inclined column 10 is made to rest against the lower curved portion 11 of the lower horizontal bar 5. At this time, the pillar 6, the inclined column 10 and the lower horizontal bar 5 will be combined into a tripod for supporting the concrete slab 2. Then the hoisting device for hoisting the concrete slab 2 will be released, and the concrete slab 2 will be effectively supported, which can effectively reduce the laying work of the supporting parts. Then, concrete is poured on the top of the supporting beam 1 and completely submerges the main hook 8, the horizontal column 7, the left hook 12 or the main hook 8. When the poured concrete is solidified, the tripod composed of the pillar 6, the inclined column 10 and the lower horizontal bar 5 can also improve the stability and seismic performance of the concrete slab 2, and the whole installation process is relatively simple.

[0056] When concrete slabs 2 are installed on both sides of the upper end of the support beam 1, the concrete slab 2 on one side is installed first, and then the other concrete slab 2 is installed and hoisted. When hoisting, the left hook 12 at the adjacent position is buckled on the right hook 13, so that the two concrete slabs 2 are connected by the left hook 12 and the right hook 13 that are buckled with each other. The weight of the two concrete slabs 2 can be balanced with each other, which can significantly improve the stability of the concrete slab 2 when installed on the support beam 1, and at the same time can further reduce the laying work of the support members.

[0057] After installing the two concrete slabs 2, the top plate 19 and the vertical plate 20 are buckled into the L-shaped grooves 21 of the two concrete slabs 2. At this time, the two concrete slabs 2 are also limited by the top plate 19, thereby further improving the installation stability of the concrete slabs 2.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
