Description

Technical Field

[0001] This utility model relates to the field of waterstop technology, and more specifically to a stress-reducing waterstop with a telescopic device. Background Technology

[0002] Bridge expansion joints are a crucial component of bridge structures, allowing the bridge deck to expand or contract in response to factors such as temperature changes, humidity, vehicle loads, and earthquakes. Without proper expansion joints, bridges may suffer damage due to the thermal expansion and contraction of materials, potentially leading to structural failure. Expansion joints are equipped with waterstops to quickly drain rainwater.

[0003] Chinese patent application number 202211086938.0 discloses a replaceable dustproof expansion joint for road and bridge construction. The structure includes two load-bearing components. A dustproof plate and a waterproof strip are respectively connected to the ends of the two load-bearing components that are close to each other. The dustproof plate is located at the end of the waterproof strip closest to the bridge deck. Anchors are connected to the ends of the two load-bearing components that are far apart from each other. The product has a two-layer structure for dustproofing and waterproofing, with a dustproof shielding plate on the upper part and a waterproof strip on the lower part. However, this replaceable dustproof expansion joint for road and bridge construction still has the following problems in use:

[0004] 1. Because the two ends of the waterproof strip are installed on the load-bearing component by insertion, during the rainy season in summer, a large amount of rainwater will flow over the waterproof strip, increasing its weight and causing it to fall off.

[0005] 2. When rainwater falls on the waterproof strip, because the two sides of the waterproof strip have curved surfaces, some rainwater will flow to the edge and come into contact with the load-bearing components, causing the load-bearing components to rust and other problems. At the same time, it will also cause the accumulation of sand and gravel on both sides, which will affect the subsequent drainage capacity.

[0006] Therefore, it is necessary to propose a stress-reducing and water-stopping mechanism for expansion joints to solve the above problems. Utility Model Content

[0007] To address the above problems, this utility model provides a stress-replaceable waterstop with a telescopic device, which enhances the waterproofing between the stress-replacement waterstop and the edge beam steel, while also improving the load-bearing capacity of the stress-replacement waterstop to cope with the large amount of water during the rainy season.

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] A stress-replaceable waterstop for a telescopic device includes a stress-replaceable waterstop located between two adjacent side beam steel sections. The bottom of the side beam steel section is provided with a base plate, and a cavity is formed between the side beam steel section and the base plate. The stress-replaceable waterstop includes a connecting strip and a fixing strip located on both sides of the connecting part. The top of the fixing strip is provided with a wedge-shaped strip, and the wedge-shaped strip and the fixing strip are located in the cavity.

[0010] The middle area of ​​the connecting strip is provided with a downward-facing bent portion. A horizontal support portion is provided at the connection between the fixing strip and the connecting strip. The horizontal support portion is located at the top of one end of the base plate. An upper step portion and a lower step portion are provided between the fixing strip and the horizontal support portion. A boss portion that cooperates with the lower step portion is provided in the cavity. A right-angle portion that cooperates with the upper step portion is provided at the bottom of the wedge strip.

[0011] Preferably, the top of the wedge-shaped strip is provided with an outer inclined surface that slopes toward the side beam steel, and the top of the cavity is provided with an inner inclined surface that matches the outer inclined surface.

[0012] Preferably, a stop block is provided on one side of the wedge-shaped strip, located above the right angle portion.

[0013] Preferably, the stress-resistant waterstop is made of EPDM material.

[0014] Preferably, a support platform is connected to the opposite side of the two side beam steel sections, and a dustproof plate is connected to the top of the support platform.

[0015] Preferably, the dustproof plate includes a dustproof plate and a shock-absorbing plate located at the bottom of the dustproof plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This device has a wedge-shaped strip component at the top of the fixing strip. The wedge-shaped strip has the function of squeezing and fixing the fixing strip, which improves the tensile strength of the stress waterstop, allowing the stress waterstop to bear more rainwater to cope with the rainy season. At the same time, it improves the waterproofing ability of the connection.

[0018] 2. This device has a downward-facing bend in the middle of the stress-resistant waterstop. The bend guides rainwater towards the center, reducing the contact between rainwater and the side beam steel and preventing rust. At the same time, in conjunction with the wedge strip, it increases the height on both sides, increasing the waterproofing and sand and gravel accumulation prevention capabilities on both sides.

[0024] 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.

[0025] Please see Figure 1-3 A stress-reducing waterstop for a bridge expansion joint includes a stress-reducing waterstop 102 located between two adjacent side beam steel sections 101. The side beam steel sections 101 are connected to adjacent bridge sections, and the two adjacent side beam steel sections 101 form a bridge expansion joint. The top is used for vehicle passage, and the bottom of the side beam steel section 101 is provided with a base plate 103. A cavity 104 is formed between the side beam steel section 101 and the base plate 103. The cavity 104 is used to accommodate both ends of the stress-reducing waterstop 102, which can release the stress-reducing waterstop from both sides of the side beam steel section 101. The water hose 102 is pulled out to replace the stress waterstop 102, which is convenient and quick. The stress waterstop 102 includes a connecting strip 105 and a fixing strip 106 located on both sides of the connecting part. The connecting strip 105 is used for the flow of rainwater, and the fixing strip 106 is used to fix it in the cavity 104. The top of the fixing strip 106 is provided with a wedge-shaped strip 107, which plays a squeezing and fixing role to stabilize the stress waterstop 102 in the cavity 104. The wedge-shaped strip 107 and the fixing strip 106 are located in the cavity 104.

[0026] The connecting strip 105 has a downward-facing bend 108 in its middle area. The bend 108 is downward-facing so that when rainwater falls on the stress-retaining waterstop 102, it flows towards the bend 108, preventing rainwater from flowing to the sides and causing sand and gravel accumulation. A horizontal support 109 is provided at the connection between the fixing strip 106 and the connecting strip 105. The horizontal support 109 is located at the top of one end of the base plate 103, supporting the stress-retaining waterstop 102. The fixing strip 106... Between the 6 and the horizontal support 109, there is an upper step 110 and a lower step 111. The lower step 111 is used to be locked in the cavity 104, and the upper step 110 is used to cooperate with the wedge strip 107 to increase the stability during connection. The cavity 104 is provided with a boss 112 that cooperates with the lower step 111. The boss 112 blocks the lower step 111 to prevent the fixing strip 106 from being pulled out of the cavity 104. The bottom of the wedge strip 107 is provided with a right angle portion 113 that cooperates with the upper step 110. The right angle portion 113 is used to cooperate with the upper step 110.

[0027] Specifically, refer to Figure 1 and Figure 2 The top of the wedge-shaped strip 107 is provided with an outer inclined surface 114 that is inclined toward the side beam steel 101, which facilitates the installation of the wedge-shaped strip 107 into the cavity 104. The bottom of the wedge-shaped strip 107 is blocked by the upper step portion 110, so it will not easily come out of the cavity 104. The top of the cavity 104 is provided with an inner inclined surface 115 that cooperates with the outer inclined surface 114.

[0028] Specifically, refer to Figure 1 and Figure 2 The wedge-shaped strip 107 has a stop 116 located above the right angle portion 113 on one side. The stop 116 serves a positioning function, making it easy to position the strip during installation and also easy to hold when pulling the wedge-shaped strip 107.

[0029] Specifically, the stress-resistant waterstop 102 is made of EPDM material, which has the advantages of corrosion resistance and resistance to high and low temperatures.

[0030] Specifically, refer to Figure 1 and Figure 3 A support platform 117 is connected to the opposite side of the two side beam steel sections 101. The support platform 117 is used to support the dustproof plate 118. The top of the support platform 117 is connected to the dustproof plate 118. The dustproof plate 118 is used to prevent foreign objects such as gravel from entering the area between the two side beam steel sections 101 and has a blocking function. Specifically, the support platform 117 is provided with a drainage hole 119 for the rapid discharge of rainwater and impurities.

[0031] Specifically, refer to Figure 1 and Figure 2 The dustproof plate 118 includes a dustproof plate and a shock-absorbing plate located at the bottom of the dustproof plate. The top dustproof plate is used to prevent sand and gravel from entering, and the bottom shock-absorbing plate plays a role in shock absorption.

[0032] In this embodiment, when rainwater falls on the stress waterstop 102, it will be affected by the bending part 108, thus moving towards the middle position of the stress waterstop 102, reducing the contact between rainwater and the side beam steel 101. The wedge strip 107 is used to hold the fixing strip 106 in the cavity 104, which improves the load-bearing capacity of the stress waterstop 102. When the stress waterstop 102 needs to be disassembled, the wedge strip 107 is first pulled out from both sides, then the stress waterstop 102 to be replaced is pulled out from both sides, then the new stress waterstop 102 is put in, and finally the wedge strip 107 is retracted into the cavity 104.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
