[0047] The utility model provides a concrete component and its assembly, and a construction method, which have high construction efficiency, good waterproof effect, and are convenient for on-site installation and subsequent maintenance.

[0048] Please refer to Figures 1 to 6 In the embodiment of the present application, a concrete component 100 is provided, and the concrete component 100 is used to be installed on the opening of a trench 200 to block the trench 200.

[0049] In the embodiment of the present application, the concrete component 100 may specifically be a concrete cover plate, which is used to be installed on the opening of the trench 200 .

[0050] The concrete cover plate may include: a plate-like body. The plate-like body includes: a top surface 110 and a bottom surface 120 arranged opposite to each other along the thickness direction, and a side surface surrounded by the top surface 110 and the bottom surface 120. Specifically, the side surface may include a first side surface 101, a second side surface 102, a third side surface 103 and a fourth side surface 104 connected in sequence. Of course, in some embodiments, it is not excluded that the side surface of the plate-like body includes three side surfaces or includes more than five side surfaces. In the embodiment of the present application, the side surface of the plate-like body is described by taking four side surfaces as an example. On the whole, the plate-like body may be a rectangular plate with a predetermined thickness, and the projection of the plate-like body on the first side surface 101 and the third side surface 103 along the thickness direction forms two parallel long sides, and the projection of the plate-like body on the second side surface 102 and the fourth side surface 104 along the thickness direction forms two parallel short sides.

[0051] Chamfers 130 of predetermined sizes are formed at the junctions of the first side surface 101 , the second side surface 102 , the third side surface 103 , and the fourth side surface 104 with the top surface 110 .

[0052] By using the chamfer 130, a filling space for filling the sealant 4 can be formed when the concrete cover is assembled to the opening of the trench 200. Specifically, the projection of the plate-like body along the thickness direction at the first side surface 101 and the third side surface 103 forms two parallel long sides, and the projection of the plate-like body along the thickness direction at the second side surface 102 and the fourth side surface 104 forms two parallel short sides; the chamfer 130 at the long side is used to cooperate with the chamfer 130 at the long side of the adjacent concrete member 100 to form a first filling space filled with the sealant 4; the chamfer 130 at the short side is used to cooperate with the side wall 202 of the trench 200 to form a second filling space filled with the sealant 4.

[0053] In addition, it should be noted that along the extension direction of the trench 200, the trench 200 has a starting side wall and an ending side wall, and the long sides of the concrete components 100 located at both ends are also respectively matched with the starting side wall and the ending side wall of the trench 200, and the long sides cooperate with the starting side wall and the ending side wall of the trench 200 to form a filling space for filling the sealant 4.

[0054] This type of concrete cover plate in the embodiment of the present application, because a filling space for filling the sealant 4 is formed by setting a chamfer 130, it is possible to eliminate the operating steps of mixing mortar, mortaring on the trench wall, mortar filling and the like in the prior art, thereby speeding up the construction progress; since the sealant 4 used in the present application has good adhesion to concrete and is ductile, the waterproof effect is significantly better than that of mortar; when maintenance is required, when the concrete cover plate needs to be opened, the sealant 4 can be cut with a knife, etc., which saves time and effort; the sealant 4 is a chemical product and can be purchased on demand according to the actual usage.

[0055] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the cross section of the concrete component 100 perpendicular to the long side direction is hexagonal, and the interface of the concrete component 100 perpendicular to the short side direction is hexagonal.

[0056] like Figure 3 As shown, in the front view of the concrete component 100, the concrete component 100 is hexagonal, which can be understood as a hexagonal structure formed by providing chamfers 130 at the two upper corners of a rectangle.

[0057] like Figure 5 As shown, in the left view of the concrete component 100, the concrete component 100 is hexagonal, which can also be understood as a hexagonal structure formed by providing chamfers 130 at the two upper corners of a rectangle.

[0058] Specifically, the size of the chamfer 130 is greater than 10 mm×10 mm; the size of the chamfer 130 is not greater than 1 / 3 of the thickness of the plate-like body.

[0059] In this embodiment, the chamfer 130 is mainly illustrated as a 45° chamfer 130. Of course, in other embodiments, the degree of the chamfer 130 can also be set to other angles, which will not be described one by one in this application.

[0060] In order to ensure that the chamfer 130 forms a space sufficient for the sealant 4 to achieve a better sealing effect, the size of the chamfer 130 can be set to be greater than 10 mm×10 mm. In addition, when the size of the chamfer 130 increases to a certain size, if the size of the chamfer 130 is further increased, the improvement of the sealing effect is no longer significant, but may affect the strength of the edge cloth of the concrete component 100. Therefore, the size of the chamfer 130 is not greater than 1 / 3 of the thickness of the plate-like body. In a specific embodiment, the size of the chamfer 130 can be 20 mm×20 mm.

[0061] In some embodiments, the trench 200 may include a bottom wall 201 and a side wall 202, the side wall 202 having a lower end face connected to the bottom wall 201, and an upper end face facing away from the bottom wall 201, the upper end face is provided with an opening 210 whose depth matches the thickness of the plate-like body, and the plate-like body is gap-fitted with the opening 210.

[0062] In this embodiment, an opening 210 may be provided on the upper end surface of the side wall 202 of the trench 200. The opening 210 is used to fit with the side clearance of the plate-like body, thereby facilitating the installation and removal of the concrete cover plate.

[0063] Specifically, along the long side direction, the gap between the side of the plate-like body and the opening 210 is between 5 mm and 10 mm. For example, along the long side direction of the plate-like body, the dimension of the plate-like body overlapping the opening 210 can be 100 mm, and the gap between the side of the plate-like body and the opening 210 can be 5 mm.

[0064] The present application also provides a concrete assembly in an embodiment, the concrete assembly mainly includes the above-mentioned concrete component 100, and the concrete assembly can achieve the technical effect achieved by the empty concrete component 100 embodiment by setting the concrete component 100. For details, please refer to the specific description of the above-mentioned embodiment, and the present application will not repeat them here. The concrete assembly can also include: a trench 200, the width of the trench 200 is smaller than the long side of the concrete component 100, so that the concrete component 100 can overlap at the opening of the trench 200 and can block the opening of the trench 200.

[0065] In one embodiment, the trench 200 is provided at its uppermost end with an opening 210 for cooperating with the concrete member 100 for installation, and the opening 210 is in a stepped shape with a sudden change in the opening cross-section.

[0066] In this embodiment, the trench 200 can be a cast-in-place concrete trench 200. The concrete component 100 can be made on-site or prefabricated in batches in a prefabrication plant. The trench 200 is provided with a stepped opening 210 at the top.

[0067] Furthermore, a protective structure 220 is provided at the junction of the opening 210 and the side wall 202 of the trench 200 , and the protective structure 220 has a first abutting surface for contacting the concrete component 100 .

[0068] When the concrete component 100 is installed at the opening 210 , the protective structure 220 can be used to protect the opening 210 , and at the same time, the flatness of the first abutting surface can be ensured.

[0069] In a specific embodiment, the protective structure 220 can be an angle steel, which is a pre-buried angle steel, with a thickness of 4 mm to 6 mm, and a side width of the angle steel that is smaller than the contact length of the concrete component 100 and the trench 200 in the long side direction. For example, the side width of the angle steel can be 50 mm. When the angle steel is of the above size, it can meet the above-mentioned functions of ensuring flatness and protecting the corner of the opening 210 of the trench 200. If the size of the angle steel is further increased, on the one hand, the cost may increase, and on the other hand, the sealant 4 may contact the angle steel.

[0070] Based on the concrete assembly provided in the above embodiment, a construction method of a concrete assembly is also provided in the embodiment of the present application. The construction method may include the following steps:

[0071] A trench 200 of a certain size is cast in situ with concrete, the trench 200 comprising a bottom wall 201 and a side wall 202, the side wall 202 having a lower end face connected to the bottom wall 201 and an upper end face away from the bottom wall 201, the upper end face being provided with an opening 210 having a depth matching the thickness of the plate-like body; an angle steel is pre-buried at the junction of the opening 210 and the side wall 202 of the trench 200;

[0072] After the trench 200 reaches the designed strength and the cables are installed in the trench 200, a plurality of concrete members 100 with chamfers 130 on four sides are installed at the opening 210 in a clearance fit manner, and the bottom surface 120 of the concrete member 100 contacts the angle steel;

[0073] The gap between the chamfers 130 of two adjacent concrete components 100 and the gap between the concrete component 100 and the side wall 202 are sealed with a sealant 4 .

[0074] The construction method provided in the embodiment of the present application can be used to cast a concrete trench 200 on site, and the concrete component 100 (hereinafter referred to as the cover plate) can be manufactured on site or mass-produced in a prefabricated factory. After the side walls 202 and the bottom wall 201 of the trench 200 reach the design strength and the cables in the trench are installed, the cover plate is covered and a sealant 4, such as a waterproof sealant, is applied. During maintenance, the sealant is cut with a tool and the cover plate is opened for maintenance. After the maintenance is completed, the cover plate is replaced and the waterproof sealant is reapplied.
