Description

Technical Field

[0001] The utility model relates to the technical field of assembled bridges, in particular to an assembled bridge slope adjustment structure. Background Art

[0002] Prefabricated bridges, also known as prefabricated assembled bridges, are a type of bridge construction in which the main components are prefabricated in a factory or specialized facility and then transported to the construction site for rapid assembly. Currently, the slope of the bridge pavement can be adjusted during assembly.

[0003] For example, the Chinese patent publication number CN111206509A states, "A prefabricated bridge slope adjustment support system includes a lower prefabricated quick-install distribution beam mounted on a support base, a prefabricated bridge slope adjustment support frame mounted on the lower prefabricated quick-install distribution beam, an upper prefabricated quick-install distribution beam mounted on the upper side of the prefabricated bridge slope adjustment support frame, and a prefabricated slab corner support frame mounted on the upper side of the upper prefabricated quick-install distribution beam; the prefabricated bridge slope adjustment support frame includes a support upright, an upper adjustment screw, an upper adjustment nut, a lower adjustment screw, a lower adjustment nut, and a connecting truss; the support upright includes an upright body and a truss support lug assembly; the truss support lug assembly includes four truss support lugs, the truss support lugs having guide blind holes; the connecting truss includes a truss body and truss plates matching the guide blind holes; the prefabricated slab corner support frame includes an adjustable screw support rod and a slab corner device."

[0004] The above-mentioned reference documents can meet the needs of different bridge types during construction, eliminating the traditional method of using different sizes and requiring a lot of cutting and welding, which results in a lot of material waste and increased construction costs. The assembled distribution beam does not require a lot of cutting or welding during use, and different sizes can be used in different specifications, which greatly saves construction costs. The present invention improves material utilization, increases the construction safety factor, is simpler and more convenient to operate than the traditional erection method, and solves the high difficulty of supporting the corner formwork along the plate in the traditional construction method.

[0005] However, when the above-mentioned prefabricated bridge slope adjustment is assembled and applied, the assembly connection between the bridge slope frame and the jacking pole and the distribution beam is relatively scattered. After assembly, the overall connection has fewer stress points and poor stability. Utility Model Content

[0006] The purpose of the utility model is to provide a prefabricated bridge slope adjustment structure, which can achieve a firm connection between assembled structural parts and improve the stability of the prefabricated bridge slope adjustment.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an assembled bridge slope adjustment structure, including a bridge slope frame, a lifting pole, a first distribution beam, a truss, a second distribution beam, and a supporting pole. First connecting poles are fixedly installed between two groups of supporting poles located on the same side of the bridge slope frame, and second connecting poles are installed at equal intervals on both sides of the outer periphery of the bridge slope frame and the first distribution beam. The second connecting pole includes a connecting rod passing through both sides of the bridge slope frame and the first distribution beam, and fastening nuts are fixedly installed at both ends of the connecting rod. The connecting rod fixes the bridge slope frame and the first distribution beam to the lifting screw rods at both ends of the second connecting pole.

[0008] Preferably, the lifting rod includes a lifting adjustment nut rotatably connected to the top and bottom, and the lifting rod also includes two sets of lifting screw rods threadedly connected to the lifting adjustment nut, and the lifting screw rods at the upper and lower ends of the lifting rod are respectively assembled and fixed to the first distribution beam.

[0009] Preferably, the supporting upright, the first connecting upright and the second connecting upright are all of the same structure as the lifting upright, and the lifting screw rods at both ends of the supporting upright are respectively assembled and fixed with the second distribution beam and the first distribution beam on one side of the bridge slope frame.

[0010] Preferably, trusses are symmetrically fixedly installed between the jacking poles arranged in parallel and at equal intervals, and side plates are respectively welded at the inner corners of the trusses.

[0011] Preferably, connecting seats are welded at equal intervals on the outer circumference of the jacking pole, mounting holes are opened through the top of the connecting seats, and the side plates outside the truss are fixedly connected to the mounting holes on the top of the connecting seats outside the jacking pole by bolts.

[0012] Preferably, the ends of the connecting rods respectively pass through the outer sides of the lifting screw rods in the second connecting vertical rods on the same side.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In the present invention, the two sides of the bridge slope frame are supported by the second distribution beam and the first distribution beam through supporting uprights, and the two groups of supporting uprights in the same plane are obliquely fixed by the first connecting uprights, so that the two groups of supporting uprights in the same plane are obliquely fixed, thereby improving the stability of the connection between the two adjacent groups of supporting uprights in the same plane, and the upper and lower groups of first distribution beams are penetrated by the connecting rods in the second connecting uprights with equal spacing on the outside and are fixed with fastening nuts, so that the integrity of the connection between the bridge slope frame and the upper and lower groups of first distribution beams is enhanced. This ensures a firm connection between the assembled structural parts, improves the stability of the slope adjustment of the assembled bridge, and solves the problem that the assembly connection between the bridge slope frame and the lifting uprights and distribution beams is relatively scattered, and after assembly, the overall connection has fewer stress points and poor stability.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-4The utility model provides a technical solution: an assembled bridge slope adjustment structure, comprising a bridge slope frame 1, a lifting pole 2, a first distribution beam 3, a truss 4, a second distribution beam 5, and a support pole 6. A first connecting pole 7 is fixedly installed between two groups of support poles 6 on the same side of the bridge slope frame 1;

[0024] Second connecting rods 8 are installed at equal intervals on both sides of the outer periphery of the bridge slope frame 1 and the first distribution beam 3. The second connecting rod 8 includes a connecting rod 81 that passes through both sides of the bridge slope frame 1 and the first distribution beam 3. Fastening nuts 82 are fixedly installed at both ends of the connecting rod 81. The connecting rod 81 fixedly connects the bridge slope frame 1 and the first distribution beam 3 to the lifting screw rods 21 at both ends of the second connecting rod 8 respectively;

[0025] By adjusting the lifting adjustment nut 22 at the end of the jacking pole 2, the lifting screw rods 21 at both ends of the jacking pole 2 can be raised and lowered to adjust the height. Under the synchronous adjustment of the upper and lower first distribution beams 3, the bridge slope frame 1 can adjust the slope during assembly. This technical solution is an existing technical solution for prefabricated bridge slope adjustment and will not be described in detail here.

[0026] The two sides of the bridge slope frame 1 are supported by the second distribution beam 5 and the first distribution beam 3 through supporting uprights 6, and the two groups of supporting uprights 6 in the same plane are obliquely fixed by the first connecting uprights 7, so that the two groups of supporting uprights 6 in the same plane are obliquely fixed, which improves the stability of the connection between the two adjacent groups of supporting uprights 6 in the same plane. The upper and lower groups of first distribution beams 3 are penetrated by the connecting rods 81 in the second connecting uprights 8 with equal spacing on the outside and are fixed with fastening nuts 82, so that the integrity of the connection between the bridge slope frame 1 and the upper and lower groups of first distribution beams 3 is enhanced, thereby stabilizing the connection between the assembled structural parts and improving the stability of the slope adjustment of the assembled bridge.

[0027] Among them, the jacking pole 2 includes a lifting and adjusting nut 22 that is rotatably connected at the top and bottom, and the jacking pole 2 also includes two groups of lifting screw rods 21 that are threadedly connected to the lifting and adjusting nuts 22. The lifting screw rods 21 at the upper and lower ends of the jacking pole 2 are respectively assembled and fixed with the first distribution beam 3. The supporting pole 6 and the first connecting pole 7 and the second connecting pole 8 have the same structure as the jacking pole 2. The lifting screw rods 21 at both ends of the supporting pole 6 are respectively assembled and fixed with the second distribution beam 5 and the first distribution beam 3 on one side of the bridge slope frame 1. The trusses 4 are symmetrically fixedly installed between the jacking poles 2 arranged in parallel and at equal intervals, and side plates 41 are respectively welded at the inner corners of the trusses 4. The lifting and adjusting nuts 22 at the ends of the jacking pole 2 are adjusted so that the lifting screw rods 21 at both ends of the jacking pole 2 can be lifted and lowered to adjust the height. Under the synchronous adjustment of the upper and lower first distribution beams 3, the slope of the bridge slope frame 1 can be adjusted during assembly.

[0028] Among them, connecting seats 23 are welded at equal intervals on the outer circumference of the jacking rod 2, and mounting holes are opened on the top of the connecting seat 23. The side plates 41 on the outside of the truss 4 are respectively fixedly connected to the mounting holes on the top of the connecting seat 23 on the outside of the jacking rod 2 by bolts, and the ends of the connecting rod 81 respectively penetrate into the outer side of the lifting screw rod 21 in the second connecting rod 8 on the same side. The adjacent jacking rods 2 are fixed and supported by bolts through the truss 4, thereby improving the stability of the entire prefabricated bridge slope frame. The two sides of the bridge slope frame 1 are supported by the supporting rods 6 between the second distribution beam 5 and the first distribution beam 3, and the two groups of supporting rods 6 in the same plane are obliquely fixed by the first connecting rod 7, so that the two groups of supporting rods 6 in the same plane are obliquely fixed, and the upper and lower groups of first distribution beams 3 are penetrated by the connecting rod 81 in the second connecting rod 8 at equal intervals on the outside and fixed with a fastening nut 82, so that the integrity of the connection between the bridge slope frame 1 and the upper and lower groups of first distribution beams 3 is enhanced.

[0029] Working principle: When in use, after the bridge ramp 1 is assembled, the two sides of the bridge ramp 1 and the second distribution beam 5 and the first distribution beam 3 are supported by support rods 6, and the two groups of support rods 6 in the same plane are fixed obliquely by the first connecting rods 7, so that the two groups of support rods 6 in the same plane are fixed obliquely, thereby improving the stability of the connection between the two adjacent groups of support rods 6 in the same plane;

[0030] Then, the second connecting uprights 8 are assembled at equal intervals on the outside of the upper and lower groups of first distribution beams 3. The upper and lower groups of first distribution beams 3 are penetrated by the connecting rods 81 in the second connecting uprights 8 at equal intervals on the outside and are fixed with fastening nuts 82, so that the integrity of the connection between the bridge slope frame 1 and the upper and lower groups of first distribution beams 3 is enhanced, which stabilizes the connection between the assembled structural parts and improves the stability of the slope adjustment of the assembled bridge.
