Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a trestle structure for bridge pier construction. Background Technology

[0002] A pier is a simple bridge structure, but when a pier needs to cross a wide body of water or bear a large load, it also needs piers as support points. Piers provide stable support for the pier, especially when it needs to cross deep water or places with large waves. Piers can make the pier more solid and improve its load-bearing capacity.

[0003] In the existing technology of bridge pier construction trestle structures, most of them are only supported and connected by bridge piers at the bottom of the trestle frame. However, when a lot of pedestrians walk on the bridge surface, the trestle frame is under pressure. After long-term use, the middle of the trestle frame between each bridge pier may deform downward, and the two ends will lift upward, affecting the safety of the trestle and causing the bridge surface to be uneven. Utility Model Content

[0004] The purpose of this utility model is to provide a trestle structure for bridge pier construction, in order to solve the problem mentioned in the background art that most of the existing bridge pier construction trestle structures are only supported and connected by bridge piers at the bottom of the trestle frame. However, when many pedestrians walk on the bridge surface, the trestle frame is under pressure. After long-term use, the middle of the trestle frame between each bridge pier may deform downward, and the two ends will lift upward, affecting the safety of the trestle and causing unevenness of the bridge surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a trestle structure for bridge pier construction, comprising a bridge pier, a trestle frame, and trestle panels. A bracket is provided above the bridge pier, and two sets of trestle frames are spliced ​​above the bracket. Limiting plates are installed above both sets of trestle frames. The middle part of the limiting plate is fixedly connected to the trestle frame, and the two ends of the limiting plate are fixedly connected to the bracket. The limiting plates and the trestle panels are arranged and installed on the upper surface of the trestle frame.

[0006] Preferably, the upper edges of both ends of the trestle frame are provided with recesses, and the size of the limiting plate matches the recesses.

[0007] Preferably, the joint between the two sets of trestle frames is located at the center of the bracket.

[0008] Preferably, the length of the bracket is taken as the extension direction of the trestle bridge, and the length of the bracket is greater than the size of the bridge pier.

[0009] Preferably, the bracket has protruding edges at both ends in the width direction, and the width dimension of the trestle frame matches the dimension between the protruding edges.

[0010] Preferably, a damping layer assembly is installed between the bracket and the pier. The damping layer assembly includes a first connecting plate, a pressure-bearing plate, a damping component, and a second connecting plate. The first connecting plate is installed and fixed above the pier. Multiple sets of damping components are evenly arranged between the pressure-bearing plate and the first connecting plate. The pressure-bearing plate is installed and fixed below the bracket through the second connecting plate.

[0011] Preferably, the system also includes triangular supports, with two sets of triangular supports distributed on both sides of the pier and connected to the damping layer assembly. The top of the triangular supports is screwed to a pressure plate, and the sides of the triangular supports are screwed to the pier.

[0012] Preferably, the damping layer assembly is provided in two sets, which are symmetrically arranged about the bridge pier.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting a limiting plate, the trestle frame is fixed to the bracket by the limiting plate. The lower part of the ends of all trestle frames is constrained by the bracket, and the upper part is constrained by the limiting plate. The limiting plate applies a downward force on the trestle frame at both ends, reducing the risk of trestle frame deformation, keeping the trestle frame straight, improving the quality of the trestle, and extending the service life of the trestle.

[0015] 2. By setting up a large-size bracket, the length of the bracket increases the connection position with the two side bridge frames and also increases the contact area of ​​the supporting bridge frames, making walking on the bridge board more stable. At the same time, when the bridge board bears a large load, the middle of the bridge frame between each pair of piers is not easily deformed. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] One embodiment provided by this utility model: as follows Figure 1 As shown, a trestle structure for pier construction includes a pier 1, a damping layer component 2, a bracket 3, a limiting plate 4, a trestle frame 5, and a trestle plate 6.

[0024] like Figure 2 and Figure 3 As shown, two sets of damping layer components 2 are installed between the bracket 3 and the pier 1, symmetrically arranged about the pier 1. The damping layer components 2 include a first connecting plate 21, a bearing plate 22, a damping element 23, and a second connecting plate 24. The first connecting plate 21 is fixed above the pier 1. Multiple sets of damping elements 23 are evenly arranged between the bearing plate 22 and the first connecting plate 21. The bearing plate 22 is fixed below the bracket 3 via the second connecting plate 24. When a pedestrian walks on the trestle slab 6 above the bracket 3, the trestle frame 5 experiences pressure from the trestle slab 6, which is transmitted to the bracket 3 supporting the trestle frame 5. Under the action of the damping elements 23, the bracket 3 moves downward to buffer the pressure, thereby reducing the pressure of the bracket 3 on the pier 1 and improving the safety of the trestle. Furthermore, the symmetrically distributed damping layer components 2 ensure that the pressure of the bracket 3 on the pier 1 is balanced, preventing eccentric pressure from affecting the stability of the pier 1.

[0025] like Figure 4 As shown, each group of damping layer components 2 is equipped with two sets of triangular supports 11. The triangular supports 11 are distributed on both sides of the pier 1 and connected to the damping layer components 2. The top of the triangular supports 11 is screwed to the pressure plate 22, and the side of the triangular supports 11 is screwed to the pier 1. The triangular supports 11 stably support the pressure plate 22 to keep it horizontal and without deformation, and horizontally support the bracket 3. Therefore, the pressure applied by the bracket 3 to the pier 1 is vertically downward, and the pier 1 is not prone to tilting to one side. At the same time, the triangular supports 11 increase the support area and improve the stability of the pier 1 supporting the trestle bridge.

[0026] With the extension direction of the trestle bridge as the longitudinal direction, the length of the bracket 3 is greater than the size of the pier 1. Two sets of trestle bridge frames 5 are spliced ​​above the bracket 3, and the splice seam between the two sets of trestle bridge frames 5 is located at the center of the bracket 3. The larger length of the bracket 3 increases the connection points with the trestle bridge frames 5 on both sides, and also increases the contact area supporting the trestle bridge frames 5, making walking on the trestle bridge 6 more stable. At the same time, when the trestle bridge 6 bears a large load, the middle of the trestle bridge frame 5 between each pair of piers 1 is less prone to deformation.

[0027] The bracket 3 has protruding edges 31 at both ends in the width direction, and the width dimension of the trestle frame 5 matches the dimension between the protruding edges 31. The bracket 3 limits the lateral sides of the trestle frame 5, and even if the connection parts loosen after long-term use, the bracket 3 can ensure that the trestle frame 5 is not prone to displacement, thus increasing the stability of the trestle.

[0028] Limiting plates 4 are installed on top of both sets of trestle frames 5. Recesses 51 are provided on the upper edges of both ends of the trestle frame 5, and the dimensions of the limiting plates 4 match the recesses 51. The middle of the limiting plates 4 is fixedly connected to the trestle frame 5, and the two ends of the limiting plates 4 are fixedly connected to the protruding edges 31 of the brackets 3. When many pedestrians walk on the trestle frame 5, after prolonged use, the middle of the trestle frame 5 may deform downwards, and the two ends may warp upwards, affecting the safety of the trestle and causing unevenness on the bridge surface. Here, the trestle frame 5 is fixed to the brackets 3 by the limiting plates 4. The lower ends of all trestle frames 5 are constrained by the brackets 3, and the upper ends are constrained by the limiting plates 4. The limiting plates 4 apply a downward force to the trestle frames 5 at both ends, reducing the risk of deformation, keeping the trestle frames 5 straight, improving the quality of the trestle, and extending its service life.

[0029] The limiting plate 4 and the trestle frame 5, except for the recessed part 51, are at the same height. Trestle plates 6 are installed on the upper surfaces of the limiting plate 4 and the trestle frame 5. The trestle plates 6 are laid flat on the entire surface of the trestle.

[0030] The above are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
