Description

Technical Field

[0001] The utility model relates to the technical field of bridges, and more specifically to a railway beam end waterproof device which is convenient for construction and maintenance. Background Art

[0002] The expansion device of railway bridge is set at the expansion joint between adjacent beam ends or between the beam body and the abutment breast wall. It plays the role of adapting to the expansion creep of the beam body, preventing slag and waterproofing, and is an important bridge accessory. The device must meet the requirements of free expansion and contraction of the bridge in two directions parallel and perpendicular to the bridge axis, prevent rainwater from penetrating the expansion structure, prevent ballast or garbage from entering the expansion joint or falling from the beam through the expansion joint, affecting pedestrians or vehicles below, and also prevent rainwater and sewage from flowing into the beam end and the end of the prestressed anchor head at the beam end, which will cause the rust of the prestressed anchor to affect the service life of the beam body.

[0003] The commonly used railway bridge waterproofing device at present is composed of anchoring profiles arranged on both sides of the expansion joint and a rubber waterstop connected therebetween. The anchoring profiles at both ends respectively fix and seal the two ends of the rubber waterstop through the internal cavity. When the existing structure is in use, it takes a long time to replace the rubber waterstop, the construction process is cumbersome, time-consuming and labor-intensive, and the construction process requires a lot of manpower and material resources, which greatly increases the maintenance cost. At the same time, during use, the two ends of the rubber waterstop are very easy to separate from the anchoring profiles, thereby failing to meet the waterproofing requirements.

[0039] The utility model is described in detail below.

[0040] like Figure 1-Figure 2 As shown:

[0041] A railway beam end waterproof device that is easy to construct and maintain, comprising two groups of first profile components that are symmetrically arranged and have a slot 11, a sealing strip 3 that is arranged between the two groups of first profile components and connected to the two groups of first profiles, and a T-shaped material 2 for pre-pressing the two ends of the sealing strip 3 into the slot 11;

[0042] Both ends of the sealing strip 3 are respectively provided with slots for inserting and fitting with the T-shaped material 2;

[0043] The slot 11 has an opening and the opening is inclined, and the angle formed with the horizontal plane is A, 90°>A>0°.

[0044] When in use, firstly install the two groups of first profile components, and arrange the two groups of slots 11 on the side close to each other, and then install the sealing strip 3;

[0045] When installing the sealing strip 3, first insert the two ends of the sealing strip 3 into the card slot 11 respectively, and then insert the T-shaped material 2 into the slot respectively. During the insertion process, the T-shaped material 2 will apply a force to the sealing strip 3, so that the sealing strip 3 is deformed and fits and abuts against the inner side surface of the card slot 11;

[0046] The inclined arrangement of the card slot 11 can effectively prevent the sealing strip 3 from slipping out of the card slot 11 during use. The sealing strip 3 can be fitted and abutted against the two sides of the card slot 11 by the coordinated use of the T-shaped material 2 and the slot to achieve a sealed connection and prevent water leakage at this position. At the same time, since the space at this position is small, the inclined arrangement will make it more convenient to install and disassemble the sealing strip 3. The two sets of card slots 11 are inclined to form Figure 1 The opening of the card slot of the described figure eight structure, which is smaller at the top and larger at the bottom, is tilted upward;

[0047] The specific tilt angle can be adjusted according to the on-site space;

[0048] When replacing, the T-shaped material 2 is directly taken out from the slot, and the sealing strip 3 will no longer be squeezed, so it will be restored to its original state, and the sealing strip 3 can be taken out from the slot. Compared with the existing technology, the installation and removal is more convenient, and the maintenance cost is greatly reduced;

[0049] In some possible implementations, in order to further strengthen the sealing connection between the two ends of the sealing strip 3 and the card slot 11;

[0050] The clamping slot 11 is in a U-shaped structure, and C-shaped limiting slots 12 communicating with the clamping slot 11 are respectively arranged on both sides of the U-shaped structure.

[0051] The C-shaped limiting grooves 12 are symmetrically arranged on both sides of the U-shaped structure, and cooperate with the card slot 11 to form a chamber with a large middle and small ends. After the mounting portion 31 is installed in the card slot 11, it will be squeezed by the T-shaped material 2 to deform the mounting portion 31, and its outer side surface will abut against the bottom of the C-shaped limiting groove 12. Each group of C-shaped limiting grooves 12 and the inner side surface on the same side of the U-shaped structure will form an inner concave structure. The outer side surface of the deformed mounting portion 31 is located in the inner concave structure, further preventing the sealing strip 3 from slipping out of the card slot 11. At the same time, since two C-shaped limiting grooves 12 are arranged on one side of the card slot 11, there will be no gap after the mounting portion 31 is deformed, so that the location has good sealing and waterproof performance;

[0052] In some possible implementations, in order to allow the sealing strip 3 to deform and abut against two side surfaces of the slot 11 after the T-shaped bar 2 is inserted;

[0053] The sealing strip 3 comprises two sets of mounting parts 31 with the same structure and respectively mounted in the two sets of slots 11 and pressed and matched with the C-shaped limit slots 12, and a main body section 32 disposed between the two sets of mounting parts 31 and respectively connected to the two sets of mounting parts 31;

[0054] Furthermore, the main body section 32 is disposed between the two sets of mounting portions 31 and is integrally formed, and the two sets of mounting portions 31 are disposed to achieve effective connection between the sealing strip 3 and the first profile assembly;

[0055] In some possible implementations, in order to achieve noise reduction during use;

[0056] The main body section 32 is provided with a cavity noise reduction structure;

[0057] Furthermore, the cavity noise reduction structure includes any one of a mesh structure, a parallelogram structure, a triangle structure, a circular structure, and a strip structure.

[0058] In some possible implementations,

[0059] The slot is disposed in the mounting portion 31 , and the small end of the T-shaped bar 2 is inserted into the slot and applies a pressing force to the mounting portion 31 .

[0060] In some possible implementations, in order to effectively squeeze the mounting portion 31 through the T-shaped bar 2, the outer side surface of the mounting portion 31 is abutted against the two side surfaces of the slot 11 to achieve sealing;

[0061] The small end of the T-profile 2 includes a connecting section connected to its large end, and an extrusion boss 21 connected to the side of the connecting section away from the small end and having a cross-sectional size larger than the cross-sectional size of the connecting section. The extrusion boss 21 is inserted into the slot to apply pressure to the mounting portion 31, causing the mounting portion 31 to deform and its outer side to abut against the C-shaped limit groove 12.

[0062] During the insertion, the extrusion boss 21 first enters the slot. Since its cross-sectional size is large and larger than the cross-sectional size of the slot, during the insertion process, the mounting portion 31 is pressurized, causing the mounting portion 31 to deform, and the two side surfaces of the U-shaped structure on the outer side of the mounting portion 31 and the bottom of the C-shaped limiting groove 12 are in contact with each other, so that after the installation is completed, there will be no water leakage at this part, and the sealing performance is good;

[0063] In some possible implementations, in order to effectively realize the anchoring connection between the first profile assembly and the bridge;

[0064] The first profile assembly includes a profile body 1 having a slot 11 and an anchor connected to the profile body 1;

[0065] In some possible implementations,

[0066] A dovetail groove 13 connected to the anchor is provided on the profile body 1; the anchor comprises a trapezoidal nut 4 installed in the dovetail groove 13, an anchor bolt 6 connected to the trapezoidal nut 4, and a locking nut 5 sleeved on the outside of the anchor bolt 6 and screwed to the anchor bolt 6;

[0067] The trapezoidal nut 4 is installed in the dovetail groove 13, the anchor bolt 6 is threadedly matched with the trapezoidal nut 4, and the locking nut 5 is sleeved on the outside of the anchor bolt 6. Through the abutment of the locking nut 5 and the profile body 1 on one side close to each other, the profile body 1 and the anchor are integrally anchored in the bridge and form a whole with the bridge;

[0068] In some possible implementations, in order to further enable the anchor bolt 6 to be effectively anchored in the bridge;

[0069] A limiting step is provided at one end of the anchor bolt 6 away from the trapezoidal nut 4;

[0070] Specifically, the small end of the dovetail groove 13 has an opening and is provided with a side away from the card slot 11, so that the trapezoidal nut 4 installed in the dovetail groove 13 of the mounting groove and in cooperation with the dovetail groove 13 will not slip out of the dovetail groove 13; the end of the anchor bolt 6 close to the dovetail groove 13 is provided with an external thread, and the locking nut 5 moves toward the side close to the dovetail groove 13, thereby achieving the further locking of the trapezoidal nut 4 and the profile body 1 through the locking nut 5, so that the entire profile body is anchored in the bridge as a whole.

[0071] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
