Description

Technical Field

[0001] The utility model specifically relates to an assembled box-type culvert structure. Background Art

[0002] Box culverts usually refer to a type of traffic engineering structure, a channel constructed of concrete or other solid materials, usually with a cuboid or rectangular box section. This structure is designed to provide sufficient strength and stability to withstand the traffic load above and possible water flow or other external forces, and is mostly used in roads, railways or other transportation routes.

[0003] When installing the existing assembled box culvert, the prefabricated support plate is heavy and needs to be hoisted to the designated installation position by a crane. It will shake during the hoisting, especially in an environment with strong external wind. It cannot be installed accurately and needs to be adjusted back and forth, which is troublesome and time-consuming, affecting the installation efficiency. For this reason, we propose an assembled box culvert structure. Utility Model Content

[0006] Two prefabricated support plates arranged side by side, with a prefabricated top plate arranged on the top of the prefabricated support plates;

[0007] The connection and positioning mechanism is arranged on the lower surface of the prefabricated support plate to position and connect the prefabricated support plate when it is installed;

[0008] A connecting plate is cast between two prefabricated support plates, and the connecting plate is in contact with the connecting positioning mechanism;

[0009] Wherein, the connection and positioning mechanism is provided with a protrusion which cooperates with the connection plate.

[0010] Preferably, the connecting and positioning mechanism includes a positioning base plate, a guide block and connecting bolts. The positioning base plate is fixed with a guide block, and the lower surface of the prefabricated support plate is provided with a guide groove matching the guide block. The connecting bolts are fixed to the four corners of the upper surface of the positioning base plate to be fixed to the prefabricated support plate through the positioning base plate.

[0011] Preferably, the guide block is conical, and the upper surface of the guide block is smaller than the lower surface.

[0012] Preferably, a second reinforcement bar matching with the connecting plate is fixed to one side wall of the guide block.

[0013] Preferably, a first reinforcement bar is fixed to the lower end of one side wall of the prefabricated support plate, and the first reinforcement bar cooperates with the connecting plate.

[0014] Preferably, the protrusion is cylindrical, and a plurality of the protrusions are provided.

[0015] Preferably, the connection and positioning mechanism is rectangular, and both end surfaces of the connection and positioning mechanism are flush with the side walls of the two prefabricated support plates respectively.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] By providing a positioning base plate, a guide block, connecting bolts and a connecting plate, it is convenient to accurately lift the two prefabricated support plates to the predetermined installation position when assembling the culvert, and avoid the prefabricated support plates shaking back and forth when being lifted by a crane, which makes the installation more inconvenient. The device has a simple structure and can play a precise guiding effect during installation, thereby improving the installation efficiency and improving the firmness of the connection between the two prefabricated support plates through the connecting plate after installation.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 5The utility model provides a technical solution: an assembled box-type culvert structure, comprising:

[0026] Two prefabricated support plates 1 are arranged side by side, and a prefabricated top plate 2 is arranged on the top of the prefabricated support plates 1;

[0027] The connection and positioning mechanism 3 is arranged on the lower surface of the prefabricated support plate 1, and is used to position and connect the prefabricated support plate 1 when installing it, so as to facilitate the positioning and installation of the two prefabricated support plates 1, improve the effect of installing them in place at one time during installation, and avoid the prefabricated support plate 1 from shaking back and forth during hoisting, which affects the installation effect;

[0028] The connecting plate 4 is cast between the two prefabricated support plates 1, and the connecting plate 4 is in contact with the connecting positioning mechanism 3;

[0029] Among them, a protrusion 5 cooperating with the connecting plate 4 is provided on the connecting positioning mechanism 3, so as to improve the connection firmness between the connecting positioning mechanism 3 and the connecting plate 4 after installation, thereby improving the connection firmness effect of the connecting plate 4 on the two prefabricated support plates 1.

[0030] In this embodiment, preferably, the connecting and positioning mechanism 3 includes a positioning base plate 31, a guide block 32 and a connecting bolt 33. The guide block 32 is fixed on the positioning base plate 31, and a guide groove 6 matching the guide block 32 is opened on the lower surface of the prefabricated support plate 1, so as to facilitate guiding the prefabricated support plate 1 when hoisting it to avoid rocking back and forth and causing installation deviation. The connecting bolts 33 are fixed to the four corners of the upper surface of the positioning base plate 31 to be fixed to the prefabricated support plate 1 through the positioning base plate 31.

[0031] In this embodiment, preferably, the guide block 32 is conical, and the upper surface of the guide block 32 is smaller than the lower surface, so as to better guide when the prefabricated support plate 1 is slowly hoisted.

[0032] In this embodiment, preferably, a second reinforcement bar 321 matching with the connecting plate 4 is fixed to one side wall of the guide block 32 , so as to improve the firmness of the connection with the connecting plate 4 .

[0035] In this embodiment, preferably, the connection and positioning mechanism 3 is rectangular, and both end surfaces of the connection and positioning mechanism 3 are flush with the side walls of the two prefabricated support plates 1, respectively, to facilitate a better supporting effect.

[0036] The working principle and use process of the utility model are as follows: when in use, the lightweight positioning base plate 31 is laid to the predetermined position, and then the prefabricated support plate 1 is hoisted above the positioning base plate 31 by a crane. When the prefabricated support plate 1 slowly approaches the positioning base plate 31, the guide block 32 cooperates with the guide groove 6 to guide the prefabricated support plate 1 to the predetermined installation position at one time. At this time, the positioning base plate 31 and the prefabricated support plate 1 can be fixed by connecting bolts 33. Similarly, another prefabricated support plate 1 can be installed to the predetermined position at one time, and then the prefabricated top plate 2 is hoisted to the top of the prefabricated support plate 1, and the connecting plate 4 is cast between the two prefabricated support plates 1. By cooperating with the protrusion 5, the second reinforcement bar 321, and the first reinforcement bar 7 and the connecting plate 4, the two prefabricated support plates 1 and the connecting positioning mechanism 3 can be connected to form a whole, thereby improving the stability and strength after installation.
