Description

Technical Field

[0001] The utility model belongs to the technical field of parking lot ground construction, in particular to an anti-sag structure of a parking lot floor. Background Art

[0002] The process of people parking in underground parking lots is divided into two steps: driving in and driving out. For some larger shopping malls, there are many vehicles coming and going, and the number of vehicles entering and leaving the parking lot is very frequent. Therefore, the anti-sag ability of the parking lot floor is required to be relatively high, especially for the road section entering the parking lot floor. When the vehicle goes downhill, the speed of the vehicle is relatively faster than when it has entered the parking lot floor. Not only that, a certain centrifugal force will be generated during the downhill process of the vehicle. For this section of the road where the vehicle gets off, higher requirements are put forward for its anti-sag ability. In the existing technology, most parking lot floors have a single structure. Over time, it is easy to cause the ground to sink and produce depressions during the downhill process of the vehicle, and there is a problem of insufficient anti-sag ability.

[0003] To this end, we proposed a parking lot floor anti-sag structure to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that in the existing technology, most parking lots have a single floor structure, which over time can easily cause the ground to sink and form a depression when vehicles go downhill, and the anti-sag ability is insufficient. A parking lot floor anti-sag structure is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A parking lot floor anti-sag structure includes a foundation, which is located at the lowest end of the structure. The foundation cross-section is arc-shaped. The foundation is penetrated by a plurality of load-bearing walls arranged along the foundation cross-section. The load-bearing walls are parallel to the tangent position of the foundation. A steel bar bracket is fixedly arranged between every two load-bearing piles, a load-bearing layer is fixedly arranged above the load-bearing piles, and a buffer layer is fixedly arranged on the load-bearing layer.

[0007] The anti-sag capability of the device is enhanced by arranging a foundation, a load-bearing wall, a steel support, a load-bearing layer and a buffer layer.

[0008] Preferably, the load-bearing wall is a cement stone wall, and steel piles are fixedly installed in the cement stone wall. The cement stone wall and the steel piles are parallel to the tangent position of the foundation.

[0009] By setting up load-bearing walls, radial support is provided to the vehicle when going downhill, thereby increasing its compressive strength.

[0010] Preferably, the steel bar support includes a plurality of steel bars fixedly connected to the steel piles, and the plurality of steel bars are staggeredly arranged inside the steel bars.

[0011] By arranging steel bar brackets, multiple load-bearing walls are connected to each other, thereby increasing the stability of the device.

[0012] Preferably, the load-bearing layer is provided with honeycomb pits arranged in a uniform arrangement, and concrete is provided in the honeycomb pits.

[0013] By setting up honeycomb pits and concrete, the strength of the upper layer of the road surface is increased.

[0014] Preferably, the buffer layer includes a sealing mortar layer located on the bottom surface, and a primer layer is fixedly arranged above the sealing mortar layer.

[0015] By setting up a closed mortar layer and a base oil layer, the friction of the road surface is increased and the safety performance of the road surface is improved.

[0016] Preferably, protective slopes are provided at both ends of the foundation, and the two protective slopes are symmetrically arranged.

[0017] By setting up a protective slope, the deviation of the foundation can be reduced, which is beneficial to improving the stability of the overall structure.

[0018] Preferably, the cross-section of the protective slope is a right-angled trapezoid, and a connecting rod is provided between the two protective slopes, and the connecting rod is provided through the steel support.

[0019] By setting the shape of the protection slope and the connecting rods, the stability between the protection slopes is increased.

[0020] To sum up, the technical effects and advantages of the utility model are as follows: by setting the foundation, load-bearing walls, steel support and buffer layer, the vehicle speed is faster when the vehicle goes downhill. During the downward process, the force direction of the vehicle is always perpendicular to the tangent of the slope, so its force direction coincides with the load-bearing wall. During the movement of the car, most of the pressure is applied to the load-bearing wall. The load-bearing wall is different from the general ground structure, has a greater load-bearing capacity, and is more resistant to dents. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] Reference Figure 1-3 A parking lot floor anti-sag structure includes a foundation 1, which is located at the lowest end of the structure. The cross section of the foundation 1 is in an arc shape. The foundation 1 is penetrated by a plurality of load-bearing walls 2 arranged along the cross section of the foundation 1. The load-bearing walls 2 are parallel to the tangent position of the foundation 1. A steel support 3 is fixed between every two load-bearing walls 2. A load-bearing layer 4 is fixed above the load-bearing wall 2, and a buffer layer 5 is fixed on the load-bearing layer 4. This structure is mainly set in the section of the parking lot floor structure when the car is going downhill. The foundation 1, the load-bearing wall 2, the load-bearing layer 4 and the buffer layer 5 The entire parking lot floor structure needs to be reinforced in order to increase its anti-sag ability. On the one hand, it is necessary to strengthen the material strength in this section of the road, and on the other hand, it is necessary to add a stable structure. By setting a foundation 1 as the paving base surface of the entire structure, a load-bearing wall 2 is set on the foundation 1. When the car goes downhill, the centrifugal force and gravity of the car act on the slope surface. The load-bearing wall 2 contains steel material, which is beneficial to increase the strength of the road surface compared to the basic road surface. At the same time, the paving position is selected in a targeted manner, which not only saves materials but also achieves the purpose of increasing the anti-sag ability.

[0030] Reference Figure 1-3 The load-bearing wall 2 is a cement stone wall 21, and a steel pile 22 is fixed in the cement stone wall 21. The steel pile 22 extends into the foundation 1. The cement stone wall 21 and the steel pile 22 are parallel to the tangent position of the foundation 1. The steel pile 22 serves as the basic bearing point of the device. When the car is moving, the main action is on the steel pile 22, and the steel pile 22 transmits the force to the foundation 1, thereby reducing the concentrated impact on the road section.

[0031] Reference Figure 1-3 The steel support 3 includes a plurality of steel rods 31 fixedly connected to the steel piles 22. The plurality of steel rods 31 are staggered inside the steel rods 31. The steel rods 31 connect the steel piles 22 to each other. When the steel rods 31 are subjected to pressure, the pressure of each road section is dispersed, which is beneficial to increase the stability of the entire device.

[0032] Reference Figure 1 、 4 And 5, the load-bearing layer 4 is provided with honeycomb pits 6 arranged in a uniform arrangement, and concrete is provided in the honeycomb pits 6. The honeycomb pits 6 are arranged in a honeycomb shape, and the openings of the honeycomb pits 6 are facing the vertical direction. The built-in concrete can enhance its stability.

[0033] Reference Figure 1 and 4 The buffer layer 5 includes a closed mortar layer 51 located on the bottom surface, and a primer layer 52 is fixedly arranged above the closed mortar layer 51. The closed mortar layer 51 seals the honeycomb pit 6 to increase the pressure resistance of the ground. The primer layer 52 makes the road surface polished and clean, the base surface is dry, flat and free of hollows, which can enhance adhesion.

[0034] Reference Figure 1-3 Protective slopes 7 are set at both ends of the foundation 1. The two protective slopes 7 are symmetrically arranged. The protective slopes 7 are in contact with the foundation 1, the load-bearing wall 2, the load-bearing layer 4, the buffer layer 5 and the outer walls at both ends, which can prevent the road surface from shifting.

[0035] Reference Figure 1-3 The cross-section of the protective slope 7 is a right-angled trapezoid. A connecting rod 8 is provided between the two protective slopes 7. The connecting rod 8 is set through the steel support 3. The connecting rod 8 is connected between the two protective slopes 7 to ensure the stability of the protective slope 7, which is conducive to reducing the inclination of the road surface.

[0036] Working principle:

[0037] The foundation 1, load-bearing wall 2, load-bearing layer 4 and buffer layer 5 constitute the entire parking lot floor structure. In order to increase its anti-sag ability, the foundation 1 is set as the paving base surface of the entire structure, and the load-bearing wall 2 is set on the foundation 1. When the car goes downhill, the centrifugal force and gravity of the car act on the slope surface. The load-bearing wall 2 contains steel material, which is beneficial to increase the strength of the road surface compared to the basic road surface. At the same time, the paving position is selected in a targeted manner, which not only saves materials but also achieves the purpose of increasing the anti-sag ability. The connecting rod 8 connected between the two protective slopes 7 can ensure the stability of the protective slope 7, which is beneficial to reducing the inclination of the road surface.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
