Technical Field

[0001] The utility model relates to a prefabricated drainage grid beam, belonging to the technical field of building prefabricated parts. Background Art

[0002] Grid beams are commonly used on slopes or soil surfaces for reinforcement. Conventional grid beams are manufactured using a pre-cut groove, mold installation, and concrete pouring process. This requires a long preparation period and is physically demanding for the construction staff, making the construction process cumbersome and inefficient. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a prefabricated drainage grid beam, which solves the problem of low construction efficiency of grid beams in the prior art.

[0004] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions: a prefabricated drainage grid beam, comprising a prefabricated base, a fixed connecting block, a movable connecting block, a threaded hole, a countersunk hole and a bolt fastener, the prefabricated base being arranged in a rectangular block, the fixed connecting block being arranged on the outer side of the prefabricated base and embedded in the prefabricated base, forming a stepped structure at the side where the fixed connecting block and the prefabricated base are connected, the threaded hole being opened on the fixed connecting block, the movable connecting block being arranged in a rectangular frame shape, the movable connecting block being placed on a side of the fixed connecting block away from the prefabricated base, the countersunk hole being opened on a side of the movable connecting block away from the fixed connecting block, the countersunk hole passing through the movable connecting block toward one end of the fixed connecting block, the countersunk hole and the threaded hole being aligned, the bolt fastener being arranged in the countersunk hole, the end of the bolt fastener extending into the threaded hole and being threadedly connected to the threaded hole, a plurality of slots being aligned on the opposite inner walls of the movable connecting block, a reinforcing rod being arranged between the two aligned opposite slots, and a connecting structure being provided at both ends of the reinforcing rod, the reinforcing rod being inserted into the slot through the connecting structure and fixedly connected to the movable connecting block.

[0005] By adopting the above technical solution, multiple prefabricated bases are directly buried or cast in the ground, and adjacent prefabricated bases are abutted against each other to fix the prefabricated bases to the ground. At this time, the prefabricated movable connecting block is placed on the fixed connecting block, and bolt fasteners are inserted into the countersunk holes. The movable connecting block and the fixed connecting block are fixed by threaded connection between the bolt fasteners and the threaded holes to complete the installation of the movable connecting block. In this way, multiple movable connecting blocks are installed back and forth to form a grid beam structure. Compared with the traditional method of grooving and pouring concrete in the ground, this installation method is more efficient. The stepped structure between adjacent prefabricated bases and fixed connecting blocks can allow water to flow through to achieve the purpose of drainage. At the same time, reinforcing rods can be installed on the movable connecting block. While improving the structural strength of the movable connecting block, the middle part of the movable connecting block of the rectangular frame structure can be filled, so that the side of the grid beam structure away from the ground is changed from uneven to approximately flat, so that construction equipment and other equipment can pass normally on the movable connecting block, thereby improving the diversified application of the grid beam.

[0006] The utility model is further configured as follows: a limiting groove is provided on the side of the fixed connection block facing the prefabricated base, and a limiting block aligned with the limiting groove is fixed on the side of the movable connection block facing the fixed connection block, and the limiting block is plugged into the limiting groove.

[0007] By adopting the above technical solution, the connection between the limit block and the limit groove can ensure that the movable connection block will not slide relative to the fixed connection block during installation, so that the threaded hole and the countersunk hole are always aligned, thereby improving the installation convenience of the movable connection block.

[0008] The utility model is further configured as follows: a portion of the movable connection block where the limit block is set is provided with a plurality of prefabricated holes, the prefabricated holes extend toward the direction of the limit slot, both ends of the prefabricated holes penetrate the movable connection block, and a matching hole aligned with the prefabricated hole is provided on the inner wall of the limit slot on the side away from the movable connection block, a limiting column is inserted into the prefabricated hole, the end of the limiting column extends into the matching hole, and the gap between the prefabricated hole and the limit column is filled with cement mortar.

[0009] By adopting the above technical solution, by inserting limit columns into the prefabricated holes and pouring cement mortar, the connection strength between the movable connection block and the fixed connection block can be improved, avoiding the situation where the fixed connection block and the movable connection block fall off after the bolt fasteners fail, thereby improving the service life of the grid beam.

[0010] The utility model is further configured as follows: the connecting structure includes a sliding cavity, a through groove, a movable sleeve, an intermediate block and a plug-in rod, the sliding cavity is opened on both side end faces of the reinforcing rod, the sliding cavity extends axially along the reinforcing rod, the through groove is opened on both side end faces of the reinforcing rod, the through groove is communicated with the sliding cavity and the side of the through groove away from the sliding cavity radially penetrates the reinforcing rod, the extension direction of the through groove is the same as that of the sliding cavity and the extension length is smaller than the sliding cavity, one end of the plug-in rod is inserted into the sliding cavity, the plug-in rod slides along the extension direction of the sliding cavity, the other end of the plug-in rod extends into the slot, the intermediate block is arranged in the through groove, one end of the intermediate block is fixed to the side curved surface of the plug-in rod, the movable sleeve is arranged on the outside of the reinforcing rod, the other end of the intermediate block is fixed to the movable sleeve, and the axial length of the intermediate block along the reinforcing rod is smaller than the axial length of the through groove along the reinforcing rod.

[0011] The utility model is further configured as follows: a pressure spring is fixedly arranged between one end of the plug rod inserted into the sliding cavity and an end wall of the sliding cavity away from the opening, and the elastic force of the pressure spring presses the plug rod toward the slot.

[0012] By adopting the above technical solution, when installing the reinforcing rod, first press the movable sleeve in the direction away from the slot. At this time, the connecting rod retracts in the sliding cavity and the pressure spring is compressed. Then, after aligning the end of the connecting rod with the slot opening, release the movable sleeve, so that the connecting rod enters the slot under the elastic action of the pressure spring. At this time, both ends of the reinforcing rod are connected to the slot through the connecting rod to complete the installation of the reinforcing rod. When disassembling, you only need to press the movable sleeve in the direction away from the slot to disengage the connecting rod from the slot and disassemble the reinforcing rod. In this way, when the reinforcing rod is damaged, it can be quickly replaced, which greatly reduces the difficulty of repairing and maintaining the grid beam.

[0013] The utility model is further configured as follows: an abutting sleeve is provided on the outer side of the reinforcing rod, and the two ends of the abutting sleeve along the axial direction of the reinforcing rod respectively abut against the movable sleeves at both ends of the reinforcing rod, and the abutting sleeve limits the axial movement of the movable sleeve along the reinforcing rod.

[0014] By adopting the above technical solution, after the reinforcement rod is installed, the abutment sleeve is installed on the outside of the reinforcement rod. After the abutment sleeve is installed on the reinforcement rod, it can protect the reinforcement rod, and the end of the abutment sleeve can abut against the movable sleeve, thereby limiting the movement of the movable sleeve, preventing the plug-in rod from being separated from the slot, and improving the stability of the reinforcement rod.

[0015] The beneficial effect of the present invention is that multiple prefabricated bases are directly buried or cast on the ground, and adjacent prefabricated bases are abutted against each other to fix the prefabricated bases to the ground. At this time, the prefabricated movable connecting blocks are placed on the fixed connecting blocks, and bolt fasteners are inserted into the countersunk holes. The movable connecting blocks are fixed to the fixed connecting blocks through the threaded connection of the bolt fasteners and the threaded holes to complete the installation of the movable connecting blocks. Thus, multiple movable connecting blocks are installed back and forth to form a grid beam structure. Compared with the traditional method of grooving and pouring concrete on the ground, this installation method is more efficient. The stepped structure between the adjacent prefabricated bases and the fixed connecting blocks can allow water to flow through, thereby achieving the purpose of drainage.

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0022] like Figure 1 and Figure 3As shown, a prefabricated drainage grid beam includes a prefabricated base 10, a fixed connecting block 11, a movable connecting block 12, a threaded hole 13, a countersunk hole 14 and a bolt fastener. The prefabricated base 10 is a rectangular block. The fixed connecting block 11 is arranged on the outside of the prefabricated base 10 and is embedded and connected to the prefabricated base 10. The side of the connection between the fixed connecting block 11 and the prefabricated base 10 forms a stepped structure. The prefabricated base 10 passes through a mold and steel bars are inserted. It is formed by pouring concrete mortar in one go, and then the fixed connecting block 11 is inserted into the unsolidified prefabricated base 10. After the concrete solidifies, the prefabricated base 10 and the fixed connecting block 11 are fixedly connected. The threaded hole 13 is opened on the fixed connecting block 11, and the movable connecting block 12 is arranged in a rectangular frame shape. The movable connecting block 12 is placed on the side of the fixed connecting block 11 away from the prefabricated base 10. The countersunk hole 14 is opened on the side of the movable connecting block 12 away from the fixed connecting block 11. The countersunk hole 14 passes through the movable connecting block 12 toward one end of the fixed connecting block 11. The countersunk hole 14 is aligned with the threaded hole 13, and a bolt fastener is arranged in the countersunk hole 14. The end of the bolt fastener extends into the threaded hole 13 and is threadedly connected to the threaded hole 13. A number of slots 28 are aligned on the relative inner walls of the movable connecting block 12, and a reinforcing rod 20 is arranged between the two aligned relative slots 28. The two ends of the reinforcing rod 20 are provided with a connecting structure. The reinforcing rod 20 is inserted into the slot 28 through the connecting structure and is fixedly connected to the movable connecting block 12. The fixed connection block 11 is provided with a limiting groove 15 on the side facing the prefabricated base 10 , and the movable connection block 12 is fixed with a limiting block 16 aligned with the limiting groove 15 on the side facing the fixed connection block 11 , and the limiting block 16 is plugged into the limiting groove 15 .

[0023] like Figure 2 and Figure 3 As shown, the part of the movable connection block 12 where the limit block 16 is set is provided with several prefabricated holes 30, and the prefabricated holes 30 extend toward the direction of the limit groove 15. Both ends of the prefabricated hole 30 pass through the movable connection block 12. The inner wall of the limit groove 15 on the side away from the movable connection block 12 is provided with a matching hole aligned with the prefabricated hole 30. A limiting column 31 is inserted into the prefabricated hole 30, and the end of the limiting column 31 extends into the matching hole. The gap between the prefabricated hole 30 and the limiting column 31 is filled with cement mortar.

[0024] like Figure 2 and Figure 3As shown, the connection structure includes a sliding cavity 22, a through groove 23, a movable sleeve 24, an intermediate block 25 and a plug-in rod 26. The sliding cavity 22 is opened on both side end faces of the reinforcing rod 20. The sliding cavity 22 extends axially along the reinforcing rod 20. The through groove 23 is opened on both side end faces of the reinforcing rod 20. The through groove 23 is connected to the sliding cavity 22 and the side of the through groove 23 away from the sliding cavity 22 radially penetrates the reinforcing rod 20. The extension direction of the through groove 23 is the same as that of the sliding cavity 22 and the extension length is less than that of the sliding cavity 22. Cavity 22, one end of the plug rod 26 is inserted into the sliding cavity 22, the plug rod 26 slides along the extension direction of the sliding cavity 22, and the other end of the plug rod 26 extends into the slot 28. The intermediate block 25 is set in the through slot 23, and one end of the intermediate block 25 is fixed to the side curved surface of the plug rod 26. The movable sleeve 24 is sleeved on the outside of the reinforcing rod 20, and the other end of the intermediate block 25 is fixed to the movable sleeve 24. The axial length of the intermediate block 25 along the reinforcing rod 20 is less than the axial length of the through slot 23 along the reinforcing rod 20. In the use scenario where the reinforcing rod 20 is not subjected to force, the connecting structure can be set as a rubber rod, the end of the rubber rod is fixed to the end of the reinforcing rod 20, and the total axial length of the reinforcing rod 20 is reduced by bending deformation of the rubber rods at both ends. When the rubber rod is aligned with the slot 28, the rubber rod is released so that the end of the rubber rod is inserted into the slot 28, completing the installation of the reinforcing rod 20.

[0025] like Figure 1 and Figure 3 As shown, a pressure spring 27 is fixedly installed between the end of the plug rod 26 inserted into the sliding cavity 22 and the end wall of the sliding cavity 22 away from the opening. The elastic force of the pressure spring 27 presses the plug rod 26 toward the slot 28. An abutment sleeve 21 is sleeved on the outside of the reinforcement rod 20. The two ends of the abutment sleeve 21 along the axial direction of the reinforcement rod 20 respectively abut against the movable sleeves 24 at both ends of the reinforcement rod 20, and the abutment sleeve 21 restricts the axial movement of the movable sleeve 24 along the reinforcement rod 20.

[0026] A plurality of prefabricated bases 10 are directly buried or poured on the ground, and adjacent prefabricated bases 10 are abutted against each other to fix the prefabricated bases 10 to the ground. Figure 4As shown, the prefabricated movable connection block 12 is placed on the fixed connection block 11, and bolt fasteners are inserted into the countersunk holes 14. The movable connection block 12 is fixed to the fixed connection block 11 by threaded connection of the bolt fasteners and the threaded holes 13, completing the installation of the movable connection block 12. After the multiple movable connection blocks 12 are installed back and forth, a grid beam structure is formed. Compared with the traditional method of grooving and pouring concrete on the ground, this installation method is more efficient. The stepped structures between the adjacent prefabricated bases 10 and the fixed connection blocks 11 abut against each other to form a water guide 40. At this time, the water guide 40 can allow water to flow through to achieve the purpose of drainage. At the same time, the reinforcing rod 20 can be installed on the movable connection block 12. While improving the structural strength of the movable connection block 12, the middle part of the movable connection block 12 of the rectangular frame structure can be filled, so that the side of the grid beam structure away from the ground is changed from uneven to approximately flat, so that construction equipment and other equipment can pass normally on the movable connection block 12, thereby improving the diversified application of the grid beam.

[0027] The prefabricated base 10 can also be installed at the opening of the ground drainage channel. The prefabricated base 10 is first fixed to the ground using concrete or direct filling, and then the installation of the movable connection block 12 is completed through the above process. At this time, the movable connection block 12 can be used as a drainage grid plate of the drainage channel after installing the reinforcement rod 20, further improving the diversified application of the grid beam.

[0028] The connection between the limiting block 16 and the limiting groove 15 can ensure that the movable connecting block 12 will not slide relative to the fixed connecting block 11 during installation, so that the threaded hole 13 and the countersunk hole 14 are always aligned, thereby improving the installation convenience of the movable connecting block 12.

[0029] By inserting the limiting column 31 into the prefabricated hole 30 and pouring cement mortar, the connection strength between the movable connection block 12 and the fixed connection block 11 can be improved, thereby avoiding the fixed connection block 11 and the movable connection block 12 from falling off after the bolt fastener fails, thereby improving the service life of the grid beam.

[0030] When installing the reinforcing rod 20, first press the movable sleeve 24 in the direction away from the slot 28. At this time, the connecting rod 26 retracts in the sliding cavity 22, and the pressure spring 27 is compressed. Then, after aligning the end of the connecting rod 26 with the opening of the slot 28, release the movable sleeve 24, so that the connecting rod 26 enters the slot 28 under the elastic action of the pressure spring 27. At this time, both ends of the reinforcing rod 20 are connected to the slot 28 through the connecting rod 26, and the installation of the reinforcing rod 20 is completed. When disassembling, you only need to press the movable sleeve 24 in the direction away from the slot 28 to disengage the connecting rod 26 from the slot 28 and disassemble the reinforcing rod 20. In this way, when the reinforcing rod 20 is damaged, it can be quickly replaced, which greatly reduces the difficulty of repairing and maintaining the grid beam.

[0031] After the reinforcement rod 20 is installed, the abutment sleeve 21 is installed on the outside of the reinforcement rod 20. After the abutment sleeve 21 is installed on the reinforcement rod 20, it can protect the reinforcement rod 20, and the end of the abutment sleeve 21 can abut against the movable sleeve 24, thereby limiting the movement of the movable sleeve 24, preventing the plug-in rod 26 from being separated from the slot 28, and improving the stability of the reinforcement rod 20.
