Description

Technical Field

[0001] This invention relates to the field of engineering, and more particularly to a UHPC bridge deck rubber pad installation device. Background Technology

[0002] During the installation of UHPC bridge decks, according to the design documents, polypropylene spacers are generally required to be installed between the upper flanges of the steel beams and the bridge deck. Reliable measures must be taken to fix them to the edge of the flanges to ensure that the spacers do not move during the hoisting of the precast bridge decks and the pouring of concrete. The installation should also be tight and straight.

[0003] During the installation of UHPC bridge decks, the PVC gaskets are prone to shifting, misalignment, and unevenness, leading to prolonged installation time and low efficiency. Therefore, it is necessary to design a UHPC bridge deck rubber gasket installation device to further improve the accuracy of the UHPC bridge deck installation process. Summary of the Invention

[0004] The purpose of this invention is to provide a UHPC bridge deck rubber pad installation device, which solves the technical problems of easy movement, non-close fit and straightness of the pads during the existing UHPC bridge deck installation process, and long installation time.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A UHPC bridge deck rubber pad installation device includes a connecting plate and two clamps. The two clamps are located at both ends of the connecting plate and are respectively clamped on both sides of the beam segment. The pad is laterally clamped into the clamps of several installation devices in the same straight line, and the clamps limit and fix the pad.

[0007] Furthermore, the two brackets are a right bracket and a left bracket, with the right bracket located at the right end of the connecting plate and the left bracket located at the left end of the connecting plate. The bottoms of the connecting plate, the right bracket, and the left bracket are all attached to the upper end of the beam segment.

[0008] Furthermore, the left-side card holder includes a left-side pad first card plate, a left-side pad second card plate, and a left-side pad card holder. The left-side pad first card plate and the left-side pad second card plate are disposed on both sides of the left-side pad card holder, and the pad is disposed inside the left-side pad card holder.

[0009] Furthermore, the right-side bracket includes a right-side pad first plate, a right-side pad second plate, and a right-side pad bracket. The right-side pad first plate and the right-side pad second plate are respectively disposed on both sides of the right-side pad bracket, and the pad is disposed inside the right-side pad bracket.

[0010] Furthermore, the left bridge plate is set on the side of the left bracket, and the bending direction of the left bridge plate is opposite to the bending direction of the first left pad plate. The left bridge plate and the first left pad plate are set on the same plane.

[0011] Furthermore, the right bridge plate is set on the side of the right bracket, and the bending direction of the right bridge plate is opposite to the bending direction of the second plate of the right pad.

[0012] Furthermore, the manufacturing process of the installation device is as follows: First, select a 1mm thick steel plate, and select a steel plate of appropriate length according to the width of the beam segment. Draw areas A, B, and C on both ends of the steel plate. Areas A and C are set at the ends of the steel plate. Cut from the connection line between areas A and C. Area A is bent upwards by 90°, and area C is bent downwards by 90°. Area B is set in the inner area of ​​the end of the steel plate. Area B is separated from area A by a fixed distance. After being bent upwards, area B is positioned opposite to the bent area A. The interval between the bent area B and the bent area A is a spacer groove.

[0013] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0014] The gasket holder of this invention can fix the gasket in a fixed position, realizing the locking of the gasket at a specific position. At the same time, when installing the polypropylene gasket, the gasket does not move, ensuring a tight fit and straightness. While ensuring a tight fit and straightness, it can improve installation efficiency and shorten the installation time by half. Attached Figure Description
