DETAILED DESCRIPTION

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0040] like Figures 1 to 14 As shown, a steel-UHPC composite bridge deck module that is easy to install in this embodiment includes a plurality of bridge deck module units 100 and a plurality of expansion joint units 200 for connecting two adjacent bridge deck module units 100;

[0041] The bridge deck module unit 100 includes a UHPC prefabricated body 110; an H-shaped steel 150 is arranged on the bottom surface of the UHPC prefabricated body 110; both ends of the UHPC prefabricated body 110 are concavely provided with a casting notch 111; an adjusting device and a plurality of inverted U-shaped embedded steel bars 112 are arranged in the casting notch 111;

[0042] The adjusting device includes two adjusting units 120 arranged at intervals; each adjusting unit 120 is provided with an adjusting window 1211 and a connecting portion 1221 penetrating the adjusting window 1211 in the casting notch 111; two first transverse steel bars 130 located below the embedded steel bars 112 are connected between the connecting portions 1221 of the two adjusting units 120; and both ends of the first transverse steel bars 130 are movably connected to the connecting portions 1221 respectively;

[0043] The expansion joint unit 200 includes two steel members 210 arranged opposite to each other; a rubber belt 220 is provided between the two steel members 210; a plurality of anchor plates 230 arranged at intervals are fixed to the steel members 210; each anchor plate 230 is fixed with a first connecting rib 240 and a second connecting rib 250 fixed to the first connecting rib 240 and in a C shape; the opening of the second connecting rib 250 faces downward.

[0044] When installing the steel-UHPC composite bridge deck module that is easy to install in this embodiment, a shaping plate 30 is arranged outside the casting notch 111, and the shaping plate 30 and the casting notch 111 form a casting space for subsequent casting. The expansion joint unit 200 is placed between two adjacent bridge deck module units 100, so that the steel member 210, the anchor plate 230, the first connecting rib 240 and the second connecting rib 250 are embedded in the casting space, and each first connecting rib 240 contacts the embedded steel bar 112 in the casting notch 111 one by one, and a horizontal plate 40 is placed between the two bridge deck module units 100, as shown in FIG. Figure 2 As shown; then the two first transverse steel bars 130 are driven to move upward through the connection parts 1221 of the two adjustment units 120, and the two first transverse steel bars 130 enter the second connecting bar 250 through the opening of the second connecting bar 250 and contact the second connecting bar 250, thereby lifting the steel member 210, the anchor plate 230, the first connecting bar 240 and the second connecting bar 250 located in the casting space until the steel member 210 contacts the horizontal plate 40. At this time, the steel member 210 is blocked by the horizontal plate 40 and cannot continue to move upward, so that the top surfaces of the two steel members 210 of the telescopic unit and the top surfaces of the UHPC prefabricated body 110 are coplanar, so that the two first transverse steel bars 130 cannot move upward, and then the two first transverse steel bars 130 move away from each other until the two first transverse steel bars 130 are respectively stuck in the two ends of the second connecting bar 250, as shown in FIG. Fig.14As shown, the load bearing capacity of the expansion joint unit 200 is increased, and the installation stability of the expansion joint unit 200 is increased. At this time, the embedded steel bars 112 and the first connecting bars 240 can be firmly connected by welding;

[0045] After the embedded steel bars 112 are fixed to the first connecting bars 240, casting material is injected into the casting space to completely solidify the internal components. After the casting material is solidified, the shaping plate 30 is removed, and the rubber belt 220 is installed between the two steel components 210 of the expansion joint unit 200, and the horizontal plate 40 is moved to complete the installation of the expansion joint unit 200.

[0046] In this embodiment, two adjustment units 120 are arranged in the casting notch 111 of the UHPC prefabricated body 110, so that during installation, the two adjustment units 120 are used to synchronously drive the two first transverse steel bars 130 to move upward to lift the expansion unit, thereby achieving fine adjustment of the transverse steel bars, thereby facilitating the top surface of the steel member 210 to be coplanar with the top surface of the UHPC prefabricated body 110, thereby ensuring the precise docking between the bridge deck module unit 100 and the expansion joint unit 200, and then the two first transverse steel bars 130 are moved horizontally and inserted into the two ends of the second connecting bar 250, thereby enhancing the load bearing capacity and installation stability of the expansion joint unit 200, thereby improving the installation accuracy, reducing the construction difficulty, and facilitating improving the construction efficiency and quality.

[0047] Benru Figure 4 and Figure 5 As shown, the embodiment of the steel-UHPC composite bridge deck module that is easy to install, in some embodiments, the second transverse reinforcement 140 located between the two first transverse reinforcements 130 is also fixedly connected between the connecting parts 1221 of the two adjustment units 120. In this embodiment, by setting the second transverse reinforcement 140, during installation, the first transverse reinforcement 130 and the second transverse reinforcement 140 are driven to move upward by the two adjustment units 120, and the first transverse reinforcement 130 and the second transverse reinforcement 140 enter through the opening of the second connecting reinforcement 250 until the first transverse reinforcement 130 and the second transverse reinforcement 140 contact the second connecting reinforcement 250, and then the two first transverse reinforcements 130 are moved away from the second transverse reinforcement 140 and clamped into the two ends of the second connecting reinforcement 250, as shown in FIG. Fig.14 As shown, the second transverse reinforcement 140 and the second connecting reinforcement 250 can then be firmly connected by welding. Such an arrangement further enhances the load bearing capacity and installation stability of the expansion joint unit 200.

[0048] like Figures 3 to 8As shown, the steel-UHPC composite bridge deck module that is easy to install in this embodiment, in some embodiments, each of the adjustment units 120 includes an adjustment seat 121, a positioning plate 122 movably arranged in the adjustment seat 121, a rotating rod 123 rotatably arranged in the adjustment seat 121, and an adjustment plate 124 slidably sleeved on the rotating rod 123 and located below the positioning plate 122; the adjustment window 1211 is arranged on the adjustment seat 121; the connecting portion 1221 is arranged on the positioning plate 122; the adjustment seat 121 is cylindrical, and the adjustment window 1211 is rectangular;

[0049] The outer wall of the rotating rod 123 is provided with a first spiral groove 1231 and a second spiral groove 1232 arranged in parallel; the positioning plate 122 is slidably arranged on the outer wall of the rotating rod 123; the positioning plate 122 is elastically floatingly connected with a first bayonet 1223; the adjusting plate 124 is provided with a second bayonet 1241; the first bayonet 1223 is movably embedded in the first spiral groove 1231; the second bayonet 1241 is movably embedded in the second spiral groove 1232; the two first transverse steel bars 130 are both transmission-connected with the adjusting plate 124, so as to drive the two first transverse steel bars 130 to move apart when the adjusting plate 124 moves upward relative to the positioning plate 122.

[0050] Specifically, the adjustment seat 121 is embedded in the UHPC prefabricated body 110, and the inner wall of the adjustment plate 124 is provided with a receiving groove, and a reset spring is arranged in the receiving groove, and the first bayonet 1223 is movably embedded in the receiving groove and abuts against the reset spring. When installing the expansion joint unit 200, by driving the rotating rod 123 to rotate, the rotating rod 123 cooperates with the first bayonet 1223 through the first spiral groove 1231, and the second spiral groove 1232 cooperates with the second bayonet 1241, thereby driving the positioning plate 122 and the adjustment plate 124 to move up synchronously, and the connecting portion 1221 moves in the adjustment window 1211. The positioning plate 122 drives the first transverse steel bar 130 and the second transverse steel bar 140 to move up through the connecting portion 1221, and the first transverse steel bar 130 and the second transverse steel bar 140 enter the second connecting bar 250 through the opening of the second connecting bar 250 and abut against the second connecting bar 250, thereby connecting the steel member 210 and the anchor plate 210 located in the casting space. 30. The first connecting rib 240 and the second connecting rib 250 are lifted up until the steel member 210 contacts the horizontal plate 40. As the rotating rod 123 continues to rotate, the steel member 210 is blocked by the horizontal plate 40, so that the first latch 1223 overcomes the elastic force of the return spring and retracts into the accommodating groove, thereby coming out of the first spiral groove 1231. At this time, the positioning plate 122 cannot continue to move upward, and the adjustment plate 124 continues to move upward relative to the positioning plate 122 under the cooperation of the second spiral groove 1232 and the second latch 1241. At this time, the adjustment plate 124 drives the two first transverse steel bars 130 to move away from the second transverse steel bars 140 until the two first transverse steel bars 130 are respectively stuck in the two ends of the second connecting rib 250. Fig.14 As shown, fine adjustment of the first transverse reinforcement 130 and the second transverse reinforcement 140 is achieved in this way to ensure the contact between the second transverse reinforcement 140 and the second connecting reinforcement 250, thereby increasing the installation stability of the expansion joint unit 200 and the bridge deck module unit 100 and reducing the construction difficulty.

[0051] like Figures 7 to 11 As shown, in the embodiment of the easy-to-install steel-UHPC composite bridge deck module, in some embodiments, the positioning plate 122 is slidably provided with a transmission block 125 corresponding to the two first transverse steel bars 130; each of the transmission blocks 125 is respectively connected to the positioning plate 122 with a first spring 126;

[0052] Each transmission block 125 includes a connecting rod 1251 that slides into the connecting portion 1221 and a driving arm 1252 that extends above the positioning plate 122; the connecting rod 1251 is fixedly connected to the first transverse reinforcement 130; the driving arms 1252 of the two transmission blocks 125 are staggered with each other; the driving arms 1252 are provided with a driving inclined surface 1253; the adjustment plate 124 is provided with an adjustment frame 127; the adjustment frame 127 is provided with two push rods 1271 that are movable vertically upward and penetrate the positioning plate 122 at intervals; the two push rods 1271 respectively correspond one by one to abut against the driving inclined surfaces 1253 of the two driving arms 1252.

[0053] Specifically, the first spring 126 makes the two transmission blocks 125 approach each other, so that the two first transverse steel bars 130 are close to the second transverse steel bars 140, that is, the distance between the two first transverse steel bars 130 is the smallest at the beginning. Figure 5 When the expansion joint unit 200 is installed, the rotating rod 123 is driven to rotate, and the rotating rod 123 cooperates with the first bayonet 1223 through the first spiral groove 1231, and the second spiral groove 1232 cooperates with the second bayonet 1241, thereby driving the positioning plate 122 and the adjusting plate 124 to move up synchronously. At this time, since there is no relative movement between the positioning plate 122 and the adjusting plate 124, there is no relative displacement between the push rod 1271 and the driving arm 1252, so that the two first transverse steel bars 130 move up. After the steel member 210 contacts the horizontal plate 40, the first bayonet 1223 escapes from the first spiral groove 1231, and the adjusting plate 124 drives the adjusting frame 127 to move relative to the positioning plate 122, so that relative movement is generated between the push rod 1271 and the driving arm 1252. The push rod 1271 cooperates with the driving inclined surface 1253 of the driving arm 1252, thereby driving the transmission block 125 to slide relative to the positioning plate 122. The first spring 126 is compressed, and the transmission block 125 drives the first transverse steel bar 130 to move through the connecting rod 1251, so that the two first transverse steel bars 130 are respectively clamped into the two ends of the second connecting bar 250, as shown in FIG. Fig.14 As shown, the stability of the installation of the expansion joint unit 200 is enhanced, and the load bearing capacity of the expansion joint unit 200 is enhanced.

[0054] like Fig.10 and Fig.11 As shown, in the embodiment of the steel-UHPC composite bridge deck module that is easy to install, in some embodiments, the driving arm 1252 of the transmission block 125 is vertically extended downward by a stop arm 1254 at one end away from the connecting rod 1251. In this embodiment, the stop arm 1254 is used to keep the push rod 1271 in contact with the driving inclined surface 1253 of the driving arm 1252, so as to prevent the driving arm 1252 from being separated from the push rod 1271, and the structure is more reliable.

[0055] In the embodiment of the easy-to-install steel-UHPC composite bridge deck module, in some embodiments, the positioning plate 122 is provided with a guide hole; the adjustment plate 124 is provided with a guide column extending vertically upward; the guide column is movably inserted into the guide hole. In this embodiment, by providing the guide hole and the guide column, when the adjustment plate 124 moves relative to the positioning plate 122, the adjustment plate 124 is provided with a guide and a limit.

[0056] like Figures 7 to 9 As shown, in the embodiment of the easy-to-install steel-UHPC composite bridge deck module, in some embodiments, the edge of the positioning plate 122 extends with a guide portion 1222 adapted to the inner wall of the adjustment seat 121. In this embodiment, the stability and strength of the movement of the positioning plate 122 are enhanced by providing the guide portion 1222.

[0057] like Figures 4 to 8 As shown, in the embodiment of the easy-to-install steel-UHPC combined bridge deck module, in some embodiments, the top of the rotating rod 123 passes through the adjustment seat 121 upward; the top of the rotating rod 123 is recessed with an adjustment port 1233; the rotating rod 123 can be driven to rotate through the adjustment port 1233. In this embodiment, the adjustment port 1233 is used to screw the rotating rod 123. Preferably, the cross-section of the adjustment port 1233 is a regular hexagon, so that the rotating rod 123 can be screwed by a hexagonal wrench during installation.

[0058] like Figures 6 to 8 , Fig.12 As shown, the steel-UHPC combined bridge deck module of this embodiment is easy to install. In some embodiments, the inner wall of the adjustment seat 121 is uniformly distributed with locking grooves 1212 along the circumferential direction; the rotating rod 123 is movably provided with a first locking block 128 and a second locking block 129; the top of the first locking block 128 is movably extended into the adjustment port 1233; the side wall of the first locking block 128 is concavely provided with an accommodating cavity; one end of the second locking block 129 is movably embedded in the accommodating cavity; one end of the second locking block 129 is provided with an inclined boss 1291 in the accommodating cavity; The first locking block 128 abuts against the inclined surface of the inclined boss 1291; the other end of the second locking block 129 moves radially along the rotating rod 123 and penetrates the rotating rod 123; a second spring 1292 is connected between the second locking block 129 and the rotating rod 123; the second locking block 129 moves into the locking groove 1212 under the elastic force of the second spring 1292, and lifts the first locking block 128 through the inclined boss 1291, so that the top of the first locking block 128 protrudes into the adjustment port 1233.

[0059] Specifically, at the beginning, Figure 6As shown, the second locking block 129 is embedded in the locking groove 1212 under the elastic force of the second spring 1292, thereby locking the rotating rod 123 to prevent the rotating rod 123 from rotating, and the top of the first locking block 128 protrudes into the adjustment port 1233; when installing the expansion joint unit 200, a hexagonal wrench is inserted into the adjustment port 1233 to generate downward pressure on the first locking block 128, and the first locking block 128 moves downward. When the first locking block 128 moves downward, a thrust is generated on the second locking block 129 by cooperating with the inclined surface of the inclined boss 1291, so that the second locking block 129 overcomes the elastic force of the second spring 1292 and retracts. At this time, the second locking block 129 is disengaged from the locking groove 1212, thereby releasing the lock on the rotating rod 123. At this time, the rotating rod 123 can be screwed by cooperating with the adjustment port 1233 to fine-tune the first transverse reinforcement 130 and the second transverse reinforcement 140.

[0060] The above description is only a preferred embodiment of the present invention.
