[0002] The cap beam of a highway bridge is the main load-bearing member of the lower structure. The quality of its cast-in-place construction is not only controlled by the concrete mix ratio and pouring method, but also closely related to the construction method adopted. Only by choosing a reasonable construction method, making the formwork firm and reliable, the joints tight, and the interfaces straight, can the self-weight and construction load be resisted and the stability of the cap beam formwork support system be ensured. The support method, the hoop method, and the through-rod method are commonly used construction methods for cap beam construction. The through-rod method has no requirements for the foundation and is not only suitable for cylindrical piers but also for rectangular high pier construction.

[0044] When in use, first install the mandrel 110 in the pre-buried hole of the pier column, and use a crane or other tool to lift the steel box body 120 to the mandrel 110. The construction personnel pull the steel box body 120 at the top of the pier column until the steel box body 120 is pulled onto the mandrel 110. At this time, the axial drive gear 230 meshes with the arc-shaped teeth 111 on the mandrel 110, and the circumferential drive gear 2100 meshes with the strip-shaped teeth 112 on the mandrel 110. Subsequently, the construction personnel can start the electric push rod 370 to move the second bevel gear 320 to mesh with the first bevel gear 310, and then start the drive motor 270 to move the steel box body 120 to a suitable position on the mandrel 110. Then, the electric push rod 370 is started to disengage the second bevel gear 320 from the meshing with the first bevel gear 310. At this time, the circumferential drive gear 2100 is pulled to the regular hexagonal protrusion 340. The construction personnel observe the level 130 on the top plate 121 and adjust the drive motor 270 so that the level 130 on the steel box body 120 is adjusted to a horizontal state. At this time, the top plate 121 on the steel box body 120 is in a horizontal state, and then the steel wedge body 150 is placed on the top plate 121 of the steel box body 120. Then, the longitudinal beam can be placed on the steel wedge body 150. On the body 150, the height of the steel wedge body 150 is adjusted by screwing the adjusting nut 1130 until the longitudinal beam is adjusted to a horizontal level, and then the template can be built on the longitudinal beam and the cap beam can be cast. After the cap beam is cast, the steel wedge body 150 is removed from the top plate 121, and then the electric push rod 370 is started to make the second bevel gear 320 mesh with the first bevel gear 310, and then the drive motor 270 is started to move the steel box body 120 to the edge of the through rod 110, and then the steel box body 120 is removed from the through rod 110.

[0045] The steel wedge device of the cap beam support system in this embodiment can support the longitudinal beam more stably through the cooperation between the two steel wedge bodies 150, and can also be stably placed on the top plate 121, thereby better improving the stability of the cap beam construction.

[0046] Among them, by disposing the triangular side plate 1180 and the inclined plate 1190 , the inclined surface 1110 can be formed by the inclined plate 1190 .

[0047] The threaded rod through holes 11110 on the vertical plate 11100 and the inclined plate 1190 allow the threaded rod 1120 to pass through, so that the construction personnel can adjust the height of the two steel wedge bodies 150 by screwing the adjusting nut 1130. The L-shaped plate 1160 can be installed on the top plate 121 of the steel box body 120 through the arrangement of the strip-shaped rack 1150 and the tooth block 1230 on the sliding plate 1220, and the L-shaped plate 1160 is connected to the top plate 121 through the bolts and other connecting parts passing through the L-shaped plate through holes 1270. After the two steel wedge bodies 150 are placed on the top plate 121, the tooth block 1230 on the sliding plate 1220 is pressed against the strip-shaped rack 1150 through the pressing mechanism, thereby preventing the steel wedge bodies 150 from moving after the two steel wedge bodies 150 are placed on the top plate, thereby further improving the stability of the steel wedge device of the cap beam support system when in use.

[0048] Among them, by setting the pressing mechanism structure, the tooth block 1230 on the sliding plate 1220 can be pressed against the strip-shaped rack 1150 through the elastic force of the spring 1260, so that the cooperation between the tooth block 1230 and the strip-shaped rack 1150 can be achieved more conveniently.

[0049] In the present embodiment, by setting up a steel box structure matching the through-steel pin rod, the steel box body 120 can be installed on the through-steel pin rod 110 more conveniently, thereby avoiding the construction workers from welding steel plates on the through-steel pin rod 110 to prevent the steel wedge body 150. At the same time, the steel box body 120 can be removed from the through-steel pin rod 110 more conveniently. Compared with manually pushing the steel box body 120 to move on the through-steel pin rod 110, the labor intensity of the construction workers is better reduced; and the top plate 121 on the steel box body 120 can stably support the steel wedge body 150, thereby better improving the stability of the steel wedge device of the cap beam support system during use.

[0050] Among them, through the setting of the driving mechanism structure, the universal joint 260 can be driven to rotate through the engagement between the second bevel gear 320 and the first bevel gear 310, and the rotating shaft 250 can be driven to rotate through the connection between the universal joint 260 and the rotating shaft 250, thereby driving the rotation of the axial driving gear 230 on the rotating shaft 250, so that the construction personnel can control the driving motor 270 to rotate the axial driving gear 230.

[0051] Among them, by setting the number of universal joints 260, the driving effect of the axial driving gear 230 is better improved, and the stability of the axial driving gear 230 during rotation is also better improved.

[0052] Among them, by setting the front side plate 122 and the rear side plate 280, the installation of the sleeve 210 can be realized; by setting the lifting lug 140, the steel box body 120 can be hoisted by the rope passing through the lifting lug 140, so that the hoisting of the steel box body 120 can be realized more conveniently. By setting the reinforcing plate 2160, the structural strength of the steel box body 120 is better improved. By setting the adjustment mechanism and the level 130, the level of the top plate 121 can be adjusted, so that the two steel wedge bodies 150 can be placed horizontally on the top plate 121, thereby avoiding the displacement or tipping of the two steel wedge bodies 150 on the top plate 121, thereby better improving the stability during the construction of the cap beam. Among them, by setting the adjustment mechanism structure, the level of the steel box body 120 can be adjusted through the cooperation between the circumferential driving gear 2100 and the strip-shaped clamping teeth 112, so that the level of the steel box body 120 can be adjusted more conveniently.

[0053] Among them, through the cooperation between the electric push rod 370 and the slider 350 and the second bevel gear 320 and the circumferential drive gear 2100, the second bevel gear 320 can be meshed with the first bevel gear 310 by driving the electric push rod 370, or the electric push rod 370 can be driven to make the circumferential drive gear 2100 rotate as the rotating shaft of the drive motor 270 rotates, so that the drive motor 270 can not only drive the axial drive gear 230 to rotate, but also drive the circumferential drive gear 2100 to rotate.

[0054] Among them, through the arrangement of the strip through hole 2120, the clamping plate 2130 and the rib plate 2140, the arc groove 820 on the rib plate 2140 can be squeezed to rest against the through rod 110 in the sleeve 210 through the locking mechanism, thereby preventing the steel box body 120 from rotating by itself during use, thereby better improving the stability of the steel box equipped with the through steel pin rod during use.

[0055] Among them, through the setting of the locking mechanism, the arc groove 820 on the rib 2140 can be squeezed to abut against the through rod 110 in the sleeve 210 by screwing the screw nut 840, so that the steel box body 120 can be locked more conveniently.

[0056] Among them, by setting the arc-shaped rack 920, the fixing plate 1020 and the bolt 1060, after the position adjustment of the steel box body 120 is completed, the screw nut 840 is first screwed to make the arc-shaped rack 920 mesh with the strip-shaped clamping teeth 112, and then the screw nut 840 and the bolt 1060 are tightened in sequence, so that the arc surface 1040 on the fixing plate 1020 is pressed against the arc-shaped rack 920 to prevent the arc-shaped rack 920 from rotating, thereby preventing the steel box body 120 from rotating through the meshing between the arc-shaped rack 920 and the strip-shaped clamping teeth 112, thereby further improving the stability of the steel box equipped with the through-steel pin rod when in use. In this embodiment, in order to enable the fixing plate 1020 to better fix the arc-shaped rack 920, the arc surface 1040 and the arc surface 1040 on the arc-shaped rack 920 are rough surfaces.

[0057] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
