DETAILED DESCRIPTION

[0024] like Figures 1 to 8 As shown, the present invention provides an anti-seepage and heat-insulating device at a node of a steel box girder, comprising a first steel beam body 1, a second steel beam body 2 and an anti-seepage and heat-insulating mechanism 4 arranged adjacent to each other, wherein a groove 3 is arranged on one side opposite to the first steel beam body 1 and the second steel beam body 2, and the anti-seepage and heat-insulating mechanism 4 is arranged in the groove 3, and the anti-seepage and heat-insulating mechanism 4 is connected to the first steel beam body 1 through a first connecting component, and is connected to the second steel beam body 2 through a second connecting component; the anti-seepage and heat-insulating mechanism 4 comprises a rectangular parallelepiped frame 41, and the frame 41 is partitioned into four chambers by a plurality of vertical vertical plates 42, and a plurality of through holes 43 are arranged on the vertical plates 42, and the partitioned chambers are filled with heat-insulating material and anti-seepage material respectively, and the lower and upper layers of the heat-insulating material and the anti-seepage material can be poured with concrete, and the left and right sides of the first steel beam body 1 and the second steel beam body 2 are connected by three reinforcing ribs 46 respectively.

[0025] In this solution, the anti-seepage and heat-insulating mechanism 4 is placed in the groove 3 of the first steel beam body 1, and the two are connected by the first connecting assembly, and then the lower layer of concrete is first poured into the frame 41, and then the insulation material and the anti-seepage material are respectively poured into the adjacent chambers, and then the upper layer of concrete is sealed, and finally the groove 3 of the second steel beam body 2 is aligned with the other side of the anti-seepage and heat-insulating mechanism 4 and connected by the second connecting assembly. The anti-seepage and heat-insulating mechanism 4 of the present invention casts the insulation material and the anti-seepage material at the node of the first steel beam body 1 and the second steel beam body 2, which plays a role in absorbing the water vapor at the node and insulating the node to prevent the cold bridge effect. The first steel beam body 1 and the second steel beam body 2 are respectively connected by the first connecting assembly and the second connecting assembly, so that the connection between the three can be firm and tight, and not easy to break, which not only achieves the effect of anti-seepage and heat preservation, but also makes the first steel beam body 1 and the second steel beam body 2 tightly connected.

[0026] The first connecting component includes three vertical grooves 51 formed on the bottom surface of the groove 3 of the first steel beam body 1. The upper and lower edges of the first steel beam body 1 are horizontally provided with three first transverse grooves 52 corresponding to the vertical grooves 51, and the vertical grooves 51 are connected to the first transverse grooves 52; a horizontally sliding connecting block 53 is provided in the first transverse groove 52, and two up-and-down sliding abutting blocks 54 are provided in the vertical groove 51. The outer sides of the opposite ends of the two abutting blocks 54 are formed into a first arc surface 55, and the ends of the two abutting blocks 54 away from each other are formed into a first inclined surface 56, and the end of the connecting block 53 away from the notch of the first transverse groove 52 is formed into a second arc surface 57. Three pressing blocks 58 are provided at the end of the frame 41 facing the first steel beam body 1, and the upper and lower edges of the ends of the pressing blocks 58 are formed into a third arc surface 59.

[0027] In the present scheme, the abutment blocks 54 distributed up and down are initially close to each other. When the frame 41 is placed in the groove 3 of the first steel beam body 1, the second arc surface 57 of the pressing block 58 is inserted between the abutment blocks 54 distributed up and down, pushing the abutment blocks 54 to move up and down respectively. When the abutment blocks 54 move up and down respectively, they can abut against the connecting blocks 53 and be pushed out of the first transverse groove 52 as the abutment blocks 54 move up and down. After being pushed out, the connecting blocks 53 are connected with the second connecting assembly so that the first steel beam body 1 and the second steel beam body 2 are connected and tightened. After the pressing block 58 is inserted between the abutment blocks 54, it can also be pressed due to the squeezing force of the two, so that the frame 41 is tightly connected to the first steel beam body 1.

[0028] The second connecting component includes a second transverse groove 61 horizontally arranged at the upper and lower edges of the second steel beam body 2 and corresponding to the first transverse groove 52. Four sliding openings 62 are symmetrically distributed on the upper and lower sides of the frame 41 facing the second steel beam body 2. A lower connecting piece is arranged in the lower sliding opening 62. The lower connecting piece includes a cylinder 63 horizontally slidably arranged on the top wall of the lower sliding opening 62. A connecting block 64 is arranged at the end of the cylinder 63. Two horizontal abutting rods 65 are also arranged on the side of the connecting block 64 away from the cylinder 63. The two abutting rods 65 slide horizontally along the connecting block 64 to abut against Two L-rods 66 facing opposite directions are provided downward at the end of the rod 65, and a gap is left between the two abutting rods 65. Two notches 67 are provided on the upper and lower side walls of the groove 3 on the second steel beam body 2, and the left and right side walls of each notch 67 are provided with a receiving opening 68 for accommodating the short end of the L-rod 66; an upper connecting piece is provided in the upper sliding opening 62, and the upper connecting piece and the lower connecting piece are arranged in a mirror-symmetrical manner; four shifting rods 69 are symmetrically distributed on the upper and lower sides of the groove bottom of the groove 3 on the second steel beam body 2, and the left and right edges of the end of the shifting rod 69 are both fourth arc surfaces 691.

[0029] In this solution, after the upper layer of concrete is poured in the frame 41, the cylinder 63 is initially in a compressed state, and the groove 3 of the second steel beam body 2 is aligned with the frame 41. When the L rod 66 is aligned with the notch 67, the cylinder 63 extends to push the L rod 66 into the notch 67, and continues to move the second steel beam body 2. The lever 69 is inserted into the gap between the abutment rods 65, and the two L rods 66 are separated, so that the short end of the L rod 66 is inserted into the placement opening 68, and then the second steel beam body 2 is continued to be driven. The second steel beam body 2 pushes the abutment rod 65, and the cylinder 63 can move along the top wall of the sliding opening 62 and drive the abutment rod 65 to move inward and retract into the sliding opening 62, so that the frame 41 and the second steel beam body 2 can be tightly connected, and the second steel beam body 2 and the first steel beam body 1 are connected tightly without a gap.

[0030] A limit groove 31 is provided on the left and right side walls of the groove 3 of the first steel beam body 1 and the second steel beam body 2, two connecting grooves 411 are provided on the left and right sides of the frame body 41, a spring is provided at the bottom of the connecting groove 411, a limit block 412 is provided at the end of the spring, and a fifth arc surface 413 is provided on the side of the limit blocks 412 on the same side facing away from each other.

[0031] In the present embodiment, when the frame 41 is placed in the groove 3 of the first steel beam body 1, the spring is squeezed so that the spring compression drives the limit block 412 to enter the connecting groove 411. When the connecting groove 411 is aligned with the limit groove 31, the spring resets and pushes the limit block 412 into the limit groove 31, further enhancing the tightness between the frame 41 and the first steel beam body 1. The side of the limit block 412 close to the groove 3 of the first steel beam body 1 has a fifth arc surface 413, which can make the limit block 412 enter the groove 3 more smoothly and reduce friction. The side of the limit block 412 away from the groove 3 of the first steel beam body 1 is not provided with an arc surface, which can reduce the possibility of the limit block 412 falling out of the limit groove 31.

[0032] The connection block 53 is provided with a puncture needle 71 on its surface, and the bottom of the second transverse groove 61 can be punctured by the puncture needle 71 and is provided with a flexible bag 72 , wherein the bag 72 is wrapped with an adhesive.

[0033] In this solution, when the second steel beam body 2 approaches the first steel beam body 1, the connecting block 53 enters the second transverse groove 61 and continues to approach so that the second steel beam body 2 approaches the first steel beam body 1. The puncture needle 71 can contact and pierce the bag 72, and the adhesive in the bag 72 can flow out to fill the second transverse groove 61 and cover the side wall of the connecting block 53, thereby further improving the firmness of the connection between the second steel beam body 2 and the first steel beam body 1.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
