[0002] With the continuous increase in demand for cars, more and more underground garages are being built. There are underground garages in shopping malls and residential areas. During the construction of underground garages, the rapid construction of car ramps is an important guarantee for increasing the construction rate of underground garages.

[0003] After searching, the announcement number is CN219671903U, which discloses a conversion node for converting a concrete car ramp to a steel ramp, including a car ramp: a conversion node is arranged at the node part of the car ramp, the conversion node includes an L-support, a support pad is installed on one side of the L-support, pads are evenly distributed in the middle part of the support pad, and a shear key is inserted and installed in the middle part of the support pad.

[0004] Based on the above search combined with the existing technology, we found that;

[0005] Although the above patent has high strength at the conversion node, its overall structural strength is low. At present, most of the basement car ramps use reinforced concrete cast-in-place structures, the process is relatively complicated, the construction quality is difficult to guarantee, and the construction period is long, which affects the overall construction progress of the basement. Therefore, there are certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a prefabricated concrete slab automobile ramp node structure. By using the ramp node structure, the prefabricated ramp slabs can be made in the factory and can be directly laid on site, thereby improving construction efficiency, reducing work procedures, and ensuring construction quality.

[0007] The technical solution for achieving the purpose of the utility model is: a precast concrete slab car ramp node structure, including a plurality of structural beams, a frame beam is fixedly installed between each adjacent structural beam, a stopper is fixedly installed on the top of each structural beam, and a plurality of groups of steel casings are pre-embedded inside each structural beam, and both ends of the steel casings are threadedly connected with high-strength connecting bolts.

[0008] Preferably, a plurality of prefabricated ramp plates are fixedly installed between the tops of each adjacent structural beam via steel casings, and both sides of each prefabricated ramp plate are fixedly connected to the steel casing via high-strength connecting bolts.

[0009] Preferably, triangular reinforcing ribs are fixedly installed between the bottom of each prefabricated ramp plate and the structural beams on both sides.

[0010] Preferably, a rubber pad is fixedly installed between each of the prefabricated ramp plates and the structural beam and the stopper.

[0011] Preferably, a drainage board is fixedly installed between a pair of the structural beams located at the ends.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] First, the utility model first fixes and installs a steel casing with high-strength connecting bolts at the construction site, then manufactures the structural beam and the block by casting, and then uses the prefabricated ramp plate manufactured in the factory to fix the prefabricated ramp plate on the structural beam by high-strength connecting bolts. The set block can ensure that the prefabricated ramp plate will not slide down, and by installing a rubber pad between the prefabricated ramp plate and the structural beam, the damping performance of the rubber can be used to effectively prevent the intensity of impact or vibration, reduce the impact and vibration of the car on the overall structure, and achieve rapid construction of the car ramp by prefabrication in advance.

[0014] Second: The utility model further improves the strength of the overall structure, improves the service life and stability by arranging triangular reinforcement ribs. By arranging a drainage board, the water on the ground can be discharged through the drainage board to prevent the water from entering the underground garage or basement and affecting the use of the underground garage or basement.

[0015] The invention solves the problem that although the strength at the conversion node of the above-mentioned patent is high, the overall structural strength is low, and most of the current basement car ramps adopt reinforced concrete cast-in-place structure, the process is relatively complicated, the construction quality is difficult to guarantee, and the construction period is long, which affects the overall construction progress of the basement.

[0022] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a prefabricated concrete slab car ramp node structure through improvement. The technical solution of the utility model is:

[0024] like Figure 1-3 As shown, a precast concrete slab car ramp node structure includes multiple structural beams 1, frame beams 2 are fixedly installed between each adjacent structural beam 1, a block 5 is fixedly installed on the top of each structural beam 1, and multiple groups of steel casings 7 are pre-buried inside each structural beam 1. Both ends of the steel casings 7 are connected with high-strength connecting bolts 8 through threads. The structural strength of the overall construction can be improved by setting the frame beams 2. The use of the set steel casings 7 and high-strength connecting bolts 8 not only further strengthens the strength of the structural beam 1, but also provides support for subsequent installation.

[0025] Furthermore, a plurality of prefabricated ramp panels 4 are fixedly installed between the tops of each adjacent structural beam 1 through a steel casing 7, and both sides of each prefabricated ramp panel 4 are fixedly connected to the steel casing 7 through high-strength connecting bolts 8. The steel casing 7 and the high-strength connecting bolts 8 can firmly fix the prefabricated ramp panel 4 to prevent shaking or sliding during use, thereby improving the stability of the prefabricated ramp panel 4 during use.

[0026] Furthermore, triangular reinforcing ribs 3 are fixedly installed between the bottom of each prefabricated ramp slab 4 and the structural beams 1 on both sides, and the overall structural strength can be further improved by using the provided triangular reinforcing ribs 3.

[0027] As a further solution of the utility model, a rubber pad 9 is fixedly installed between each prefabricated ramp plate 4 and the structural beam 1 and the block 5. By installing the rubber pad 9 between the prefabricated ramp plate 4 and the structural beam 1, the damping performance of rubber is utilized to effectively prevent impact or vibration intensity, thereby reducing the impact and vibration of the car on the overall structure.

[0028] Furthermore, a drainage board 6 is fixedly installed between a pair of structural beams 1 at the ends. The drainage board 6 can improve the drainage performance of the overall structure and prevent ground water from entering the underground garage or basement, affecting the use of the underground garage or basement.

[0029] The specific working method is: first, fix the steel casing 7 with high-strength connecting bolts 8 at the construction site, cast the structural beam 1, frame beam 2 and block 5, and fix the prefabricated ramp plate 4 at the end between adjacent structural beams 1 through high-strength connecting bolts 8, and lay and fix them in sequence.

In addition, a rubber pad 9 is installed between the prefabricated ramp plate 4 and the structural beam 1. The damping performance of rubber is used to effectively prevent impact or vibration intensity and reduce the impact and vibration of the car on the overall structure. The laying slope is generally 15°.
