[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed below. The technical features in each embodiment of the utility model can be combined accordingly without conflicting with each other.

[0027] As a preferred embodiment of the present invention, this embodiment provides a steel plate wet-dry combined laying structure with rainwater collection function, the cross-sectional view is as follows: Figure 1 The dry-wet combination laying structure of the steel plate comprises a crushed stone layer 2, a concrete layer 3, a C-shaped connector 4, a dry hard cement mortar layer 7, a patterned steel plate 8, a drainage pipe 10 and a floor drain 11.

[0028] In the structure provided by the utility model, the crushed stone layer 2 is laid on the compacted and leveled foundation soil 1. The concrete layer 3 is poured on the crushed stone layer 2. Generally speaking, the thickness of the crushed stone layer 2 and the concrete layer 3 is laid to 150 mm.

[0029] The C-shaped connector 4 used in the structure provided by the utility model is specifically as follows Figure 2 The C-shaped connector 4 includes an upper flange and a lower flange which are parallel to each other and a web which is perpendicular to the upper flange and the lower flange. The upper flange and the lower flange of the C-shaped connector 4 are both provided with fixing holes.

[0030] In this embodiment, the C-shaped connector 4 is made of hot-dip galvanized channel steel, and the distance between the upper flange and the lower flange of the C-shaped connector 4 is 30 mm, that is, the height of the web is 30 mm. It should be noted that those skilled in the art can choose a C-shaped connector 4 with a distance between the upper flange and the lower flange of 30-50 mm. However, if the distance between the upper flange and the lower flange exceeds 50 mm, it is recommended to strengthen the C-shaped connector.

[0031] The C-shaped connectors 4 are fixedly spaced on the concrete layer 3. At least 4 C-shaped connectors 4 should be provided under each diamond plate 8 to be laid, respectively for supporting the four corners of the diamond plate 8. In this embodiment, standard diamond plates are used, and the size of the diamond plate 8 is 2440 mm × 1220 mm, and the gap between adjacent diamond plates 8 is set to 80 mm. Of course, those skilled in the art can also select the appropriate size of the diamond plate and set the gap according to the actual working conditions.

[0032] In this embodiment, expansion bolts pass through the fixing holes on the lower flange of the C-shaped connector 4 to fix the C-shaped connector 4 on the concrete layer 3. 6 C-shaped connectors 4 are provided under each diamond plate 8 to be laid, of which 4 are respectively for supporting the four corners of the diamond plate 8, and the other 2 are arranged on the central axis of the long side of the diamond plate 8. The upper flange of the C-shaped connector 4 is used for placing the diamond plate 8.

[0033] In the structure provided by the present utility model, a dry-mixed mortar layer 7 is poured on the concrete layer 3, and the thickness of the dry-mixed mortar layer 7 is based on the elevation of the upper flange of the C-shaped connector 4.

[0034] In order to enable the laying structure to have the function of rainwater collection, a drain pipe 10 is pre-buried at the gap between adjacent diamond plates 8 to be laid. The drain pipe 10 is pre-buried in the foundation soil 1, the gravel layer 2 and the concrete layer 3, and a geotextile for preventing soil blockage is provided at the port. A floor drain 11 is provided at one end of the water pipe 10 located on the concrete layer 3, and the other end of the drain pipe 10 extends to the main drainage pipe. As Figure 3 and Figure 4 shown, gravel is laid at the gap between adjacent diamond plates 8. The gravel 9 can prevent foreign objects from blocking the drain pipe 10 above the floor drain 11.

[0035] In this embodiment, in order to improve the overall stability of the area where the diamond plate is laid, steel bars 6 are vertically arranged at the edge of the laid diamond plate 8 to form a boundary with other paving materials. An L-shaped connector 5 is provided at the place where the steel bar 6 needs to be provided. The bottom surface of the L-shaped connector 5 is fixed on the concrete layer 3 by expansion bolts, and the vertical surface of the L-shaped connector 5 is used to fix the steel bar 6. The L-shaped connector 5 can directly use hot-dip galvanized angle steel.

[0036] Next, a construction method for the above-mentioned wet-dry combined laying structure of the diamond plate is provided, and the specific steps are as follows:

[0037] The first step: Deepening the drawing layout.

[0038] According to the area where the diamond plate 8 needs to be laid, deepen the layout of the diamond plate. The standard size of the diamond plate is 2440mm×1220mm, and the gap between adjacent diamond plates is 80mm. The principle is to arrange the standard plates symmetrically along the middle first, and mark the position of the rainwater floor drain on the drawing. Each single rainwater floor drain controls about 50m 2 or so, that is, within 50m around a single floor drain 2 All slopes towards this floor drain.

[0039] The second step: Leveling the foundation soil and burying the drain pipe.

[0040] Compact and level the foundation soil 1. According to the positioning of the deepened drawing, pre-bury the drain pipe 10 in the foundation soil 1. One end of the drain pipe 10 is successively connected to the main drainage pipe and the rainwater collection pool. The upper elevation of the drain pipe 10 needs to exceed the ground finish surface. After completion, block the pipe orifice with a rag to prevent foreign objects from entering.

[0041] The third step: Laying the graded crushed stone layer and pouring the concrete layer.

[0042] Lay the crushed stone layer 2 on the foundation soil 1. Pour concrete on the crushed stone layer 2 to form the concrete layer 3. During the concrete pouring, it is leveled while being poured, and the position where the floor drain 11 needs to be set is the lowest point. The slope around the floor drain 11 is 0.3%. The thicknesses of both the crushed stone layer 2 and the concrete layer 3 are 150mm.

[0043] The fourth step: Elastic line positioning and elevation measurement of the connector.

[0044] After the concrete layer 3 hardens, conduct elastic line positioning at the positions where the C-shaped connectors 4 need to be set on its surface. Draw elastic lines with the size of a single diamond plate as the boundary, and draw elastic lines for the setting positions of each diamond plate. The standard height of the C-shaped connector is 30mm. However, due to the inconsistent ground elevation, it is necessary to measure and check the elevation, and take the finish surface as the unified height, and process and manufacture the connectors at some positions with large differences.

[0045] The fifth step: Fixing the connector.

[0046] Six C-shaped connectors 4 are set under one diamond plate 8, and one C-shaped connector is set at each of the four sides, and one C-shaped connector is set in the middle of the two long sides of the diamond plate. Set L-shaped connectors at the boundary positions. The connectors are all fixedly connected to the concrete floor through expansion bolts.

[0047] The sixth step: Mixing and laying the dry-hard mortar.

[0048] Mix cement and sand in a ratio of 1:3 and add a small amount of water to obtain dry - hard cement mortar. Spread the dry - hard cement mortar on the concrete layer 3 and level it according to the horizontal elevation of the upper flange of the C - type connector 4. After hardening, a dry - hard cement mortar layer 7 is formed.

[0049] Step 7: Place the checkered plate and clean the gap.

[0050] Place the checkered plate 8 on the upper flange of the C - type connector 4, with the side of the checkered plate 8 flush with the web of the C - type connector 4, and clean the dry - hard cement mortar between the gaps of two adjacent checkered plates 8. The cleaning standard is that the side exposes the checkered plate and the side of the connector, and the bottom exposes the concrete floor.

[0051] Step 8: Weld connection, install floor drain, and fill with gravel.

[0052] Spot - weld the side of the checkered plate 8 to the web of the C - type connector 4. Subsequently, set the L - type connector 5 at the boundary of the laying area of the checkered plate 8. The bottom surface of the L - type connector 5 is fixed to the concrete layer 3 through expansion bolts, and the vertical surface of the L - type connector 5 is fixed to the steel bar 6 by spot - welding to enhance the stability of the overall structure. After completion, cut the drain pipe 10 so that it is flush with the concrete layer 3, and set the floor drain 11. Lay gravel in the gaps between adjacent checkered plates 8 until it is flush with the surface of the checkered plate to ensure the overall appearance is flat and beautiful. The gravel 9 above the floor drain 11 can prevent foreign objects from blocking the drain pipe 10.

[0053] The laying structure provided by the utility model connects the checkered plate and the concrete layer through a combination of dry and wet operations: through the C - type connector, the checkered plate and the concrete floor form an overhead connection, and through the dry - hard cement mortar, the area below the checkered plate is filled and connected to the concrete floor, greatly reducing the situation of abnormal noise generated by stepping on the steel plate.

[0054] There are drainage pipes and rainwater collection floor drains buried in the foundation soil and the concrete layer respectively. The floor drain is set in the gap between the checkered plates, and gravel is laid and filled above the floor drain, which can reduce the situation of foreign object blockage to a certain extent. The rainwater can flow from the floor drain, the drain pipe, and into the rainwater collection pool, realizing the function of rainwater collection.

[0055] The above - described embodiments are only a preferred solution of the utility model, but they are not intended to limit the utility model. Those of ordinary skill in the relevant technical field can still make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, all technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
