[0002] In the construction of building projects, the renovation and upgrading of outdoor floors or squares often requires the removal of the original pavement, filling or excavating to the designed height and compacting, and re-laying the pavement structure after the construction of the cushion layer. The removal of existing structures, transportation of construction waste or earthwork, and compaction are not only complex and costly, but also time-consuming and noisy. The filling operation also requires an additional settlement waiting period. Summary of the invention

[0003] The purpose of this application is to provide a construction method for a hollow paving structure, which solves the problems of complex traditional construction procedures, high costs, and long time consumption.

[0004] The purpose of this application is achieved through the following technical solutions:

[0010] S005, laying paving materials on the load-bearing frame.

[0011] Furthermore, in the above S004, after the load-bearing frame on the column is adjusted into place, a latch is passed through the first positioning hole of the ear seat on the column and the second positioning hole of the load-bearing frame to fix the column and the load-bearing frame.

[0012] Furthermore, in the above-mentioned S004, the load-bearing frame includes an outer frame rod and a reinforcing rod. The outer frame rod is first installed between two adjacent columns to form a rectangular structure without corners. Then, the outer frame rod and the reinforcing rod of the same or different load-bearing frames are connected by frame connectors. The reinforcing rods are connected to form a tic-tac-toe structure.

[0013] Furthermore, in the above-mentioned S004, the upper, middle and lower parts of the column are provided with fixed or vertically adjustable ear seats, and the columns are connected and fixed at different horizontal planes by using multiple horizontal load-bearing frames.

[0014] Furthermore, in the above S005, a plurality of inverted T-shaped steels and flat steels are installed on the load-bearing frame, two adjacent T-shaped steels are used as left and right limiters, and the T-shaped steels and flat steels are used as supports, and a plurality of paving slabs are installed on the load-bearing frame.

[0015] Furthermore, the paving grid is arranged in a horizontal and vertical staggered manner, and the cells are rectangular.

[0016] Furthermore, the columns are of uniform cross-section or columnar structures that are thick at the bottom and thin at the top. After the load-bearing frame is installed, the top surface height of the columns is consistent with the top surface height of the load-bearing frame.

The outer frame rod is connected between two adjacent columns to form a rectangular structure without corners. The reinforcing rods are connected to form a tic-tac-toe structure. The sides of the tic-tac-toe structure are connected to the outer frame rod.

[0019] Furthermore, the paving material includes paving stone slabs, and a plurality of inverted T-shaped steels are provided on the load-bearing frame. The paving stone slabs are laid between two adjacent T-shaped steels, and a flat steel supporting the paving stone slabs is provided between the two adjacent T-shaped steels; the upper surfaces of the T-shaped steels and the flat steels are provided with stone slab adhesive for sticking the paving stone slabs.

[0020] Beneficial effects of this application:

[0021] (1) The process of removing the original pavement, filling to the designed height and compacting it, and then re-laying the pavement structure after constructing the cushion layer during the renovation of outdoor floors or squares has been eliminated. The process of removing the original pavement structure, transporting slag and filling materials, and compacting the work has been eliminated, which shortens the construction time, reduces the construction cost, and saves the construction period.

[0022] (2) The paving structure is decomposed into multiple unit hollow paving structures, which achieves the consistency and universality of the components, facilitates factory-scale production, improves the production efficiency and quality of components, and also improves the integrity and consistency of the structure after paving, ensuring the strength and appearance of the paving.

[0023] (3) On-site installation is simple, reducing the labor intensity of workers. The unitized load-bearing frame is used as the basis for the operation, and steel is used as a reference for stone slab paving, which simplifies the difficulty of the operation and is conducive to the improvement of operation standardization.

[0024] (4) The load-bearing frame is a hollow structure with good drainage performance. It can quickly drain water from the ground, improve walking safety and comfort, and at the same time increase the air permeability and water permeability of the paving material, which helps maintain ecological balance and is in line with the concept of green and sustainable development.

[0025] (5) If the terrain conditions permit, the hollowed-out portion at the bottom of the load-bearing frame can also be used as a space for arranging sponge city storage and conditioning facilities, which is in line with the concept of sponge city development.

[0035] The following non-limiting examples are provided to illustrate the present application.

[0036] Example 1

[0037] refer to Figure 1 to Figure 7 As shown, a construction method of a hollow paving structure includes the following steps.

[0038] S001, calculating and determining the outer dimensions of the paving material 3 according to the design line shape of the paving material 3 and in combination with the production and processing capabilities of the paving material 3.

[0039] S002, based on the external dimensions and installation elevation of the paving material 3 to be installed, measurement and layout are performed on the original structural level to determine the installation position and height of the column 1 to form a paving grid.

[0040] S003, according to the measurement results of S002, install columns 1 at the positions and heights corresponding to the nodes of the paving grid on the original structural level. Since the columns 1 correspond to the paving grid arrangement, the installation position of the columns 1 is located at the edge of a single paving material or the gap between two paving materials.

[0041] S004, install the load-bearing frame 2 corresponding to the cell position of the paving grid on the column 1, adjust the position of the column 1 and the load-bearing frame 2 as needed, so that the column 1 and the load-bearing frame 2 are connected as a whole, and keep the horizontality of the load-bearing frame 2.

[0042] In S004, after the load-bearing frame 2 on the column 1 is adjusted into place, the latch 8 is passed through the first positioning hole 5 of the ear seat 4 on the column 1 and the second positioning hole 13 of the load-bearing frame 2 to fix the column 1 and the load-bearing frame 2.

[0043] In S004, each load-bearing frame 2 includes four outer frame rods 6 and four reinforcing rods 7. The outer frame rods 6 are first installed between two adjacent columns 1. The four outer frame rods 6 form a rectangular structure without corners, and the outer frame rods 6 form the grid bars of the paving grid. Then, the outer frame rods 6 and the reinforcing rods 7 of the same or different load-bearing frames 2 are connected by frame connectors. The four reinforcing rods 7 are connected to form a tic-tac-toe structure. The reinforcing rods 7 serve as ribs inside the paving grid cells to complete the support inside the cells.

[0044] In S004, fixed or vertically adjustable ear seats 4 are provided at the upper, middle and lower parts of the column 1, and multiple horizontal load-bearing frames 2 are used to connect and fix the column 1 at different horizontal planes. The multi-layer load-bearing frames 2 further improve the connection strength and stability of the overall structure.

[0045] S005, laying the paving material 3 on the load-bearing frame 2.

[0046] In S005, several inverted T-shaped steels 9 and flat steels 10 are fixedly installed on the load-bearing frame 2, with two adjacent T-shaped steels 9 as left and right limiters, and several paving stone slabs 12 are installed on the load-bearing frame 2 with the T-shaped steels 9 and flat steels 10 as supports.

[0047] Example 2

[0048] refer to Figure 1 to Figure 7 As shown, a hollow paving structure includes a column 1, a load-bearing frame 2 and a paving material 3.

[0049] A number of columns 1 are erected on the original structural level, and the columns 1 are arranged at the nodes of the paving grid. A number of load-bearing frames 2 are provided on the columns 1, and the load-bearing frames 2 are arranged correspondingly at the cells of the paving grid. The columns 1 and the load-bearing frames 2 together form a paving platform surface that is higher than the original structural level.

[0050] The load-bearing frame 2 is provided with paving material 3, which is connected to form a whole. The gravity and additional load borne by the paving material 3 are sequentially transmitted to the original structural level through the load-bearing frame 2 and the column 1. The paving material 3 is directly installed on the platform surface, thereby eliminating the process steps of breaking the original paving structure, transporting slag and fillers, and compacting the operation. The paving operation is directly carried out on the higher paving platform surface, which is simple and convenient, and there is no mutual influence with the original structural level.

[0051] The load-bearing frame 2 is a hollow structure with good drainage performance. It can quickly drain water from the ground, improve walking safety and comfort, and increase the air permeability and water permeability of the paving material, which helps maintain ecological balance and conforms to the concept of green sustainable development. If the terrain conditions permit, the lower hollow part of the load-bearing frame 2 can also be used as a layout space for sponge city storage and regulation facilities, which conforms to the concept of sponge city development.

[0052] The paving grid is arranged in a horizontal and vertical staggered manner, and the cells are rectangular. The columns 1 are arranged in a horizontal and vertical staggered lattice, and the load-bearing frame 2 needs to select a rectangular outline structure according to the shape of the cells. Similarly, the paving grid can also be arranged in other forms, and the corresponding shape of the load-bearing frame 2 is adjusted according to the cells.

[0053] The column 1 is a columnar structure with a uniform cross-section or a thick lower and thin upper portion. The top surface height of the column 1 is consistent with the top surface height of the load-bearing frame 2, ensuring that the column 1 and the load-bearing frame 2 form a horizontal paving working surface together.

[0054] The column 1 is provided with an ear seat 4, and the load-bearing frame 2 is placed on the ear seat 4, so that the column 1 supports the load-bearing frame 2 through the ear seat 4. The column 1 is provided with four ear seats 4 arranged in a cross shape, so that the load-bearing frame 2 can be supported from multiple positions.

[0055] The upper, middle and lower parts of the column 1 are all provided with fixed or vertically adjustable ear seats 4, so that multiple layers of load-bearing frames 2 can be arranged, and the load-bearing frames 2 of the lower layer further improve the connection strength and stability of the overall structure (the load-bearing frames 2 of the lower layer can only be arranged with outer frame rods 6 without reinforcing rods 7). The vertically adjustable ear seats 4 can adapt to the height difference of different columns 1 and ensure the horizontal arrangement of the load-bearing frames 2.

[0056] The ear seat 4 is provided with a first positioning hole 5 , the load-bearing frame 2 is provided with a second positioning hole 13 , and the latch 8 is inserted into the first positioning hole 5 and the second positioning hole 13 to achieve a fixed connection between the column 1 and the load-bearing frame 2 .

[0057] The load-bearing frame 2 includes an outer frame rod 6 and a reinforcing rod 7. The outer frame rod 6 is fixedly connected between two adjacent columns 1, and the outer frame rod 6 forms the grid bars of the paving grid. Each load-bearing frame 2 includes four outer frame rods 6 and four reinforcing rods 7. The four outer frame rods 6 form a rectangular structure without corners, so as to utilize the rectangular structure without corners to be connected and installed with two adjacent ear seats of the column 1. The four reinforcing rods 7 are fixedly connected to form a tic-tac-toe structure. The sides of the tic-tac-toe structure are fixedly connected to the outer frame rods 6. The reinforcing rods 7 serve as ribs inside the paving grid cells to complete the support inside the cells.

[0058] The paving material 3 includes a paving stone slab 12. A plurality of inverted T-shaped steels 9 are fixedly provided on the load-bearing frame 2. The paving stone slab 12 is laid between two adjacent T-shaped steels 9. A flat steel 10 supporting the paving stone slab 12 is fixedly provided between two adjacent T-shaped steels 9. The T-shaped steels 9 and the flat steels 10 are used to assist the installation of the paving stone slab 12, so as to ensure that the paving stone slab 12 is neat, does not shift, and has good aesthetic quality.

[0059] The upper surfaces of the T-shaped steel 9 and the flat steel 10 are provided with a slab adhesive 11 for sticking the paving slab 12. The slab is placed by the adhesive to ensure that the slab is stably placed on the frame.

[0060] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In the scheme of this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.
