Description

Technical Field

[0001] The utility model relates to the field of bridge engineering, in particular to a tool for assisting in sealing joints. Background Art

[0002] With the rapid development of domestic high-speed railway construction, the application of prefabricated and assembled bridge deck components has become more and more extensive. After the prefabricated bridge deck components are installed on the box girder body, the gap between the prefabricated bridge deck components and the beam surface is filled and compacted by pouring mortar.

[0003] When filling the joints between prefabricated bridge deck components and beam surfaces, existing technologies often employ mortar edge sealing. This involves first sealing the joints with mortar, and then grouting the gaps between the prefabricated bridge deck components and the beam surfaces through pre-reserved grouting ports. This pre-sealing of the joints with mortar often results in gaps in the seal due to uneven filling. This can lead to incomplete sealing and subsequent leakage during grouting. This can also result in defects such as insufficient grouting density and an uneven seal appearance, compromising the quality of the grouting seal. Utility Model Content

[0004] The purpose of the present utility model is to overcome the problem in the prior art that, when performing the filling operation of the joints between prefabricated bridge deck components and beam surfaces, mortar is used in advance to seal the joints for gap filling, which often leads to gaps in the sealing due to uneven filling slurry, thereby causing poor sealing and leakage of slurry during subsequent grouting operations, and to provide a tool for assisting in sealing the joints.

[0005] In a first aspect, the utility model provides a tool for assisting in sealing joints, comprising an edge sealing portion and a fixing portion, wherein the edge sealing portion is used to seal the gap between the bridge deck component and the beam surface, and the edge sealing portion is connected to the fixing portion, and the fixing portion is used to fix the position of the edge sealing portion relative to the gap.

[0006] By setting the edge sealing part, the size and shape of the edge sealing part are adapted to the gap between the bridge deck component and the beam surface, so that the edge sealing part can seal the gap between the bridge deck component and the beam surface, preventing the slurry from overflowing from the gap during the filling operation, replacing the prior art of using mortar to seal the gap in advance, simplifying the steps of the joint filling operation, and improving the construction efficiency; by setting the fixing part, the edge sealing part is connected to the fixing part, and when the fixing part is installed on the assembled bridge deck component, the relative position of the edge sealing part can be fixed, reducing the During the joint filling operation, the slurry squeezes the edge sealing part, causing the edge sealing part to shift, thereby increasing the probability of the edge sealing part being tightly sealed and reducing the probability of slurry leakage. After the joint filling operation is completed, the connection between the fixing part and the prefabricated bridge deck component is released, and the edge sealing part is separated from the seam, which facilitates the reuse of the tools used to assist in joint sealing. The edge sealing part is fixed by the relative position of the fixing part and the prefabricated bridge deck component, which facilitates the disassembly and recycling of the tools used to assist in joint sealing, thereby reducing construction costs.

[0007] The fixing portion may be a clamping member or a rivet member, etc. The fixing portion may be connected to the assembled bridge deck component by clamping or by riveting.

[0008] The fixing portion is a clamping member, which includes a first clamping portion and a second clamping portion. The first clamping portion and the second clamping portion are used to clamp the bridge deck member, and the edge sealing portion can be connected to the second clamping portion.

[0009] By setting the fixing part as a clamping part, the fixing part is connected to the bridge deck component by clamping, which facilitates the installation and disassembly of the tool. The clamping part is in the clamping state, which means that the clamping part tightens the bridge deck component to fix the relative position of the clamping part and the bridge deck component. By enabling the edge sealing part to be connected to the second clamping part, when the clamping part is in the clamping state, the position of the edge sealing part relative to the bridge deck component is fixed. During operation, it is only necessary to cover the edge sealing board with the seam and then tighten the clamping part to the bridge deck component to complete the fixation of the edge sealing board position, which simplifies the operation process and improves work efficiency.

[0010] The first clamping portion and / or the second clamping portion comprises an adjusting member, and the adjusting member is used to adjust the distance between the first clamping portion and the second clamping portion, and the clamping member is clamped to the bridge deck member through the adjusting member.

[0011] By setting an adjusting piece, the bridge deck component can be clamped by the adjusting piece, and then the distance between the first clamping part and the second clamping part can be adjusted according to actual needs, so that the clamping piece can be clamped on bridge deck components of different sizes, thereby improving the adaptability of tool use.

[0012] The edge sealing portion is an edge sealing plate, the clamping piece is a U-shaped clamp, and the first clamping portion and the second clamping portion are connected by a connecting rod.

[0013] The adjusting member is a screw and a nut that cooperate with each other, or can be configured as a spring. When the adjusting member is a screw and a nut that cooperate with each other, the nut is welded to the side of the first clamping portion or the second clamping portion that is close to the bridge deck member. The screw is sequentially passed through the first clamping portion or the second clamping portion and the nut and fixed to the bridge deck member. The screw clamp is then tightened or loosened by screwing the screw into or out of the clamping member.

[0014] The edge sealing portion is a 90° angle steel, one of the wing plates of the edge sealing portion is used to contact the bridge deck component, the edge sealing portion is connected to the second clamping portion through the wing plate in contact with the bridge deck component, and the position of the adjusting member arranged on the second clamping portion corresponds to the position of the edge sealing portion.

[0015] By setting the edge sealing part to 90° angle steel, the two wing plates of the edge sealing part can be in contact with the bridge deck component and the beam surface respectively, thereby improving the sealing capacity of the edge sealing part.

[0016] The model of the angle steel can be set to 45° angle steel or 135° angle steel according to actual needs.

[0017] The second clamping portion is provided with a bottom plate, the surface of the bottom plate is perpendicular to the length direction of the second clamping portion, and when one wing plate of the edge sealing portion is connected to the second clamping portion, the other wing plate of the edge sealing portion can contact the bottom plate.

[0018] By providing the bottom plate, when the bridge deck component is flush with the end surface of the beam, one of the wing plates of the edge sealing part can contact the bottom plate, thereby improving the stability of the edge sealing part when connected to the clamping member.

[0019] The bottom plate can be an angle steel segment or a steel plate.

[0020] The edge sealing portion includes at least one segment, and connecting plates are provided at both ends of the segment, and the connecting plates are used to connect two adjacent segments.

[0021] The connecting plates of two adjacent segments can be connected by riveting or welding, and several segments can be connected according to actual needs to adapt to seams of different lengths, thereby improving the convenience of using the tool.

[0022] The connecting plate is provided with a connecting hole.

[0023] By providing the connection holes, rivets or bolts can be inserted into the connection holes of the connection plates of two adjacent edge banding plates to connect them, which facilitates installation and disassembly when connecting tools.
