The bottom of the double-T slab body has several material-saving grooves arranged at intervals along its length. The material-saving grooves extend along the width of the double-T slab body. Each material-saving groove has two composite holes arranged symmetrically from left to right and penetrating the double-T slab body vertically. The composite holes consist of an upper truncated cone hole and a lower truncated cone hole arranged symmetrically from top to bottom. The upper and lower truncated cone holes have the same shape and size. The smaller end of the upper truncated cone hole is connected to the lower truncated cone hole, and the larger end is connected to the outside. The smaller end of the lower truncated cone hole is connected to the upper truncated cone hole, and the larger end is connected to the outside. The utility model also includes a truncated cone block that matches the upper or lower truncated cone hole, with a lifting ring at the smaller end of the truncated cone block.

[0005] The present invention is further configured such that: a baffle is provided at the opening of the lower truncated cone hole, one end of the baffle is blocked at the opening of the lower truncated cone hole, and the other end is rotatably connected to the double T plate body.

[0006] The present invention is further configured such that the height of the lifting ring is greater than the depth of the upper or lower frustum hole.

[0007] The present invention is further configured such that the distance between two adjacent material-saving grooves is equal.

[0008] The present invention is further configured such that the lifting ring is U-shaped.

[0009] In summary, the present invention has the following beneficial effects: The concrete double-T slab involved in the present invention, by switching the fitting of a frustum block with a lifting ring at the small end, when it is upright, the lifting ring extends out of the composite hole, and the double-T slab is convenient for lifting at this time; when it is inverted, the lifting ring is hidden, and the double-T slab is conducive to the subsequent paving of the road substrate. The shape can be changed, the use is flexible and convenient, the overall function is perfect, and the practicality is strong. Attached Figure Description

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See Figures 1 to 4 As shown, this embodiment involves a concrete double-T slab, including a double-T slab body 1 cast from concrete. The bottom of the double-T slab body 1 is provided with a plurality of material-saving grooves 2 arranged at intervals along the length direction. The material-saving grooves 2 extend along the width direction of the double-T slab body 1. The bottom of each material-saving groove 2 is provided with two composite holes 3 arranged symmetrically from left to right and penetrating the double-T slab body vertically. The composite hole 3 is composed of an upper frustum hole 31 and a lower frustum hole 32 arranged symmetrically from top to bottom. The upper frustum hole 31 and the lower frustum hole 32 have the same shape and are equal in size. The small end of the upper frustum hole 31 is connected to the lower frustum hole, and the large end is connected to the outside. The small end of the lower frustum hole 32 is connected to the upper frustum hole, and the large end is connected to the outside. It also includes a frustum block 4 that matches the upper or lower frustum hole. The small end of the frustum block 4 is provided with a lifting ring 5, which is U-shaped.

[0018] Furthermore, the height of the lifting ring 5 is greater than the depth of the upper frustum hole 31 or the lower frustum hole 32.

[0019] Furthermore, the distance between two adjacent material-saving troughs 2 is equal.

[0020] In this embodiment, when the frustum block 4 and lifting ring 5 are in the upright position, the frustum block 4 is embedded in the lower frustum hole 32 and the lifting ring 5 extends out of the composite hole 3, so the double T plate can be lifted using the lifting ring 5, which facilitates the lifting of the double T plate; when the frustum block 4 and lifting ring 5 are in the inverted position, the frustum block 4 is embedded in the upper frustum hole 31 and the lifting ring 5 is inverted and hidden at the bottom of the double T plate body 1. At this time, the upper surface of the double T plate is flat, which is conducive to the subsequent paving of the road substrate.

[0021] Example 2

[0022] See Figures 1 to 4 As shown, the concrete double-T slab involved in this embodiment is further configured, based on embodiment 1, with a baffle 6 provided at the opening of the lower frustum hole 32. One end of the baffle 6 blocks the opening of the lower frustum hole 32, and the other end is rotatably connected to the double-T slab body 1.

[0023] In this embodiment, the baffle 6 is used to block the frustum block 4 embedded in the lower frustum hole 32, preventing it from falling out.

[0024] The installation method is as follows: First, rotate the baffle 6 until the end does not block the opening of the lower frustum hole 32, then complete the installation of the frustum block 4, and finally rotate the baffle 6 until the end blocks the opening of the lower frustum hole 32 to block the frustum block 4 embedded in the lower frustum hole 32.

[0025] The concrete double-T slab involved in this utility model can be equipped with a frustum block with a lifting ring at the small end. When it is upright, the lifting ring extends out of the composite hole, making the double-T slab easy to lift. When it is inverted, the lifting ring is hidden, making the double-T slab easier to pave the subsequent road surface substrate. The shape can be changed, making it flexible and convenient to use. The overall function is complete and the practicality is strong.
