Description

Technical Field

[0001] This application relates to the field of trestle technology, and in particular to a trestle structure. Background Technology

[0002] In modern hydraulic engineering, steel trestle bridges are needed to assist in bridge construction. During the construction of existing trestle bridges, transverse I-beams need to be installed on each row of piles. The existing I-beams and piles are usually fixedly connected. Under long-term longitudinal loads, fatigue damage can easily occur at the connection between the I-beams and piles, causing problems in the installation of the I-beams. Utility Model Content

[0003] To improve the stability of the transverse beam installation, this application provides a trestle structure.

[0004] The trestle structure provided in this application adopts the following technical solution:

[0005] A trestle structure includes several rows of piles, each row of piles comprising several piles, with a transverse beam at the top of each row of piles. A first mounting groove is formed at the top of each pile, the length direction of the first mounting groove being parallel to the length direction of the transverse beam. Arc-shaped plates are provided on both sides of the first mounting groove along its width direction, and the transverse beam is located between two arc-shaped plates. The two ends of the arc-shaped plates are connected to the transverse beam.

[0006] By adopting the above technical solution, the transverse beam is installed in the first installation groove, and the transverse beam is limited by the arc plates on both sides, and the arc plates are connected to the transverse beam to realize the installation of the transverse beam; when subjected to load along the length of the trestle bridge, the arc plates play a buffering role, thereby improving the stability of the transverse beam installation.

[0007] Optionally, the first mounting groove has arc-shaped surfaces on both sides along its width direction, and the arc-shaped surfaces are adapted to the outer surface of the arc-shaped plate.

[0008] By adopting the above technical solution, the first mounting groove is provided with an arc-shaped surface that is compatible with the arc-shaped plate, which can limit the arc-shaped plate. After installation, the arc-shaped surface can limit the arc-shaped plate to further improve the stability of the transverse beam installation.

[0009] Optionally, two transverse beams are provided, and the two transverse beams are arranged parallel in the length direction and installed side by side in the first mounting groove.

[0010] Optionally, the outer perimeter walls on both sides of the pile body distributed along the length of the transverse beam are provided with reinforcing plates, the upper surface of the reinforcing plates abutting against the lower surface of the transverse beam, and the side of the reinforcing plates being installed on the pile body.

[0011] By adopting the above technical solution, a reinforcing plate is installed on the pile body, which can support the transverse beam, thereby improving the support strength of the transverse beam.

[0012] Optionally, a first mounting portion is provided on both sides of the arc-shaped plate. The first mounting portion abuts against the side of the transverse beam. The first mounting portion has a first through hole, and the transverse beam has a second through hole. The first mounting portion is provided with a bolt pair, and the bolt pair passes through the first through hole and the second through hole in sequence.

[0013] By adopting the above technical solution, the arc plate is provided with a first mounting part on both sides, and a first through hole is provided on the first mounting part. When installing the arc plate and the transverse beam, the bolt pair is sequentially inserted into the first through hole and the second through hole to connect the arc plate and the two transverse beams.

[0014] Optionally, a second mounting portion is provided at both ends of the arc-shaped plate, and the first mounting portion is slidably connected to the second mounting portion along the length direction of the transverse beam.

[0015] By adopting the above technical solution, during the installation of the transverse beam and the arc plate, there may be a situation where the first through hole and the second through hole do not align. Therefore, the first mounting part is set to a sliding state, and the position of the first mounting part can be finely adjusted during installation so that the first through hole and the second through hole are coaxially set.

[0016] Optionally, T-shaped members are pre-embedded on both sides of the pile body along the length direction of the first installation groove. The T-shaped members are provided with a first sliding groove in the vertical direction. The reinforcing plate is provided with a first sliding block, and the first sliding block is slidably connected to the first sliding groove in the vertical direction.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. The transverse beam is installed in the first mounting slot, and the transverse beam is limited by the arc plates on both sides. The arc plates are connected to the transverse beam to realize the installation of the transverse beam. When subjected to loads along the length of the trestle, the arc plates play a buffering role, thereby improving the stability of the transverse beam installation.

[0019] 2. During the installation of the transverse beam and the curved plate, there may be a situation where the first through hole and the second through hole do not align. Therefore, the first mounting part is set to a sliding state. During installation, the position of the first mounting part can be finely adjusted so that the first through hole and the second through hole are coaxially set. Attached Figure Description

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0029] This application discloses a trestle structure, referring to... Figure 1 and Figure 2 It includes several rows of pile bodies 1, several concrete strip foundations 2, and a laying plate 3. The several rows of pile bodies 1 correspond to the several concrete strip foundations 2 respectively. Each row of pile bodies 1 includes several pile bodies 1. The several pile bodies 1 are distributed along the length direction of the concrete strip foundation 2. The lower ends of the several pile bodies 1 are fixedly connected to the upper surface of the concrete strip foundation 2. The laying plate 3 is laid on the upper end of the several rows of pile bodies 1.

[0030] Reference Figure 2 , Figure 3 as well as Figure 4Each row of piles 1 has a transverse beam 5 at its upper part, located between the pile 1 and the laying plate 3. The length direction of the transverse beam 5 is parallel to the distribution direction of the piles 1 in each row. A first mounting groove 11 is provided on the upper part of the pile 1, and the length direction of the first mounting groove 11 is parallel to the length direction of the transverse beam 5. The two sides of the first mounting groove 11 along its length direction are connected to the side of the pile 1. Arc-shaped plates 6 are provided on both sides of the first mounting groove 11 along its width direction. The transverse beam 5 is located in the first mounting groove 11 and between the two arc-shaped plates 6. The arc-shaped opening of the arc-shaped plate 6 faces the transverse beam 5. In this embodiment, the two ends of the arc-shaped plate 6 are welded to the transverse beam 5.

[0031] Reference Figure 2 , Figure 3 as well as Figure 4 There are two transverse beams 5, which are located between two arc plates 6. The two transverse beams 5 are arranged in parallel along their length. In this embodiment, the two transverse beams 5 are welded and fixed.

[0032] Reference Figure 2 A truss 4 is welded to the upper surface of the transverse beam 5, and a paving plate 3 is fixed above the truss 4.

[0033] Reference Figure 4 The side walls of the first mounting groove 11 distributed along the width direction are arc-shaped to form an arc surface 12, which is adapted to the outer side surface of the arc plate 6.

[0034] Reference Figure 4 and Figure 5 The pile body 1 is provided with reinforcing plates 7 on both sides of the outer peripheral wall distributed along the length direction of the transverse beam 5. There are two reinforcing plates 7 on each side. The two reinforcing plates 7 are distributed along the width direction of the transverse beam 5. The upper surface of the reinforcing plate 7 abuts against the lower surface of the transverse beam 5, and the side of the reinforcing plate 7 is fixedly connected to the outer peripheral wall of the pile body 1.

[0035] The implementation principle of a trestle structure in this application embodiment is as follows: the transverse beam 5 is installed in the first mounting groove 11, and the transverse beam 5 is limited by the arc plates 6 on both sides, and the arc plates 6 are connected to the transverse beam 5 to realize the installation of the transverse beam 5; when subjected to a load along the length of the trestle, the arc plates 6 achieve a buffering effect, thereby improving the stability of the installation of the transverse beam 5.

[0036] Example 2:

[0037] The difference between Example 2 and Example 1 is that, referring to Figure 6 and Figure 7Both ends of the arc-shaped plate 6 are provided with a first mounting part 61, and the side of the first mounting part 61 abuts against the side of the transverse beam 5. A first through hole 611 is opened through the side of the first mounting part 61, and a second through hole is opened on the transverse beam 5. When the transverse beam 5 is installed on the pile body 1, the first through hole 611 and the second through hole are arranged coaxially. The first mounting part 61 is provided with a bolt pair 63, and the bolt pair 63 is sequentially inserted into the first through hole 611 and the second through hole.

[0038] Reference Figure 6 and Figure 7 Both ends of the arc plate 6 are integrally formed with a second mounting part 62, and the first mounting part 61 slides along the length direction of the transverse beam 5 and is connected to the second mounting part 62.

[0039] Reference Figure 6 and Figure 7 T-shaped members 13 are pre-embedded on both sides of the pile body 1 along the length direction of the first installation groove 11. The upper surface of the T-shaped member 13 is provided with a first sliding groove 131 in the vertical direction. There are two first sliding grooves 131, which are distributed along the width direction of the transverse beam 5. The reinforcing plate 7 is provided with a first sliding block 71, which slides vertically and is connected to the first sliding groove 131.

[0040] The implementation principle of Example 2 is as follows: During the installation of the transverse beam 5 and the arc plate 6, there may be a situation where the first through hole 611 and the second through hole do not align. Therefore, the first mounting part 61 is set to a sliding state. During installation, the position of the first mounting part 61 can be finely adjusted so that the first through hole 611 and the second through hole are coaxially arranged.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
