Description

Technical Field

[0001] The present application relates to the technical field of highways and municipal bridges, and in particular to a device for controlling the elevation of a cast-in-place beam bridge deck. Background Art

[0002] Cast-in-place beam construction technology is widely used in various bridge and building projects due to its flexibility, customization, and adaptability. Controlling the elevation of cast-in-place beam bridge decks is crucial in bridge construction, directly impacting the smoothness and levelness of the deck, as well as the stability and usability of the overall structure.

[0003] Usually, the elevation control of cast-in-place bridge decks usually adopts welded vertical elevation positioning steel bars. During the concrete pouring process, the top surface of the steel bars is used as the elevation control point of the top surface of the cast-in-place bridge deck. This method consumes a lot of steel bars and the vertical stiffness of the steel bars is insufficient. When the hanging beam acts on the steel scraper rail, it will cause the steel scraper rail to deflect, affecting the flatness of the bridge deck. At the same time, the steel bars are exposed on the bridge deck after pouring, which seriously affects the subsequent bridge deck washing and polishing process. Utility Model Content

[0004] In order to solve or partially solve the problems existing in the related art, the present application provides a cast-in-place beam bridge deck elevation control device, which adjusts the clamp to make the elevation of the top of the flat steel consistent with the elevation of the cast-in-place beam top plate. During the casting process, the elevation of the cast-in-place beam is controlled based on the elevation of the top of the flat steel. After completion, the flat steel and the clamp are taken out and recycled before solidification.

[0005] The first aspect of the present application provides a cast-in-place beam bridge deck elevation control device, comprising: a base, an adjustable fixture and flat steel, the base comprising a bottom plate and a support rod connected to the bottom of the bottom plate, the base is arranged at the top plate position and fixedly connected to the top plate, a mounting hole is provided on the bottom plate, the adjustable fixture comprises a bolt, a fixing nut and a clamping plate, the screw rod of the bolt passes through the mounting hole and is positioned and installed by the fixing nut, the head of the bolt is fixedly connected to a group of clamping plates, and the clamping plates constitute a U-shaped groove for limiting the installation of the flat steel.

[0006] Among them, the fixing nut is arranged on the upper part of the mounting hole and is fixedly connected to the base plate, and the screw rod passes through the fixing nut and the base plate in sequence.

[0007] The support rods are vertically connected to the four corner positions of the base.

[0008] Among them, multiple cast-in-place beam bridge deck elevation control devices are arranged at intervals on the flat steel, and the spacing of the bases is determined based on the weight of the scraping beam and the vertical stiffness of the flat steel.

[0009] The technical solution provided by this application may have the following beneficial effects:

[0010] This application provides a cast-in-place beam bridge deck elevation control device that can adjust according to changes in the cast-in-place beam top plate elevation, ensuring the quality of the bridge deck's longitudinal and transverse slopes. Compared to conventional construction, it requires fewer consumables, and the fixtures and flat steel can be removed and recycled, saving construction costs. The scraper beam movement does not cause the scraper rail to deflect, ensuring bridge deck flatness. The device has no impact on the subsequent cast-in-place bridge deck milling process, ensuring high-quality polishing. The device has a simple structure, is easy to manufacture and install, does not require complex operation and technical requirements, and is suitable for a variety of environments and construction conditions.

[0022] The technical scheme of the embodiment of the present application is described in detail below in combination with the drawings.

[0023] As Figure 1-Figure 3 The cast-in-place beam bridge deck elevation control device shown in the figure comprises a base, an adjustable fixture and a flat steel 2. The base comprises a bottom plate 5 and a support rod 6 connected to the bottom of the bottom plate 5. The support rod 6 is vertically connected to the top corner position around the base. The base is arranged at the top plate position and fixedly connected with the top plate. A mounting hole is formed in the central position of the bottom plate 5. A fixed nut 4 is arranged at the upper part of the mounting hole. The fixed nut 4 is fixedly connected with the bottom plate 5. The adjustable fixture comprises a bolt 3, a fixed nut 4 and a clamping plate 1. The shank of the bolt 3 penetrates through the mounting hole and is positioned and installed through the fixed nut 4. The head of the bolt 3 is fixedly connected with a group of clamping plates 1. The clamping plates 1 form a U-shaped groove for limiting the installation of the flat steel 2.

[0024] The reserved space in the U-shaped channel is just enough for flat steel bar 2, which is placed sideways on an adjustable fixture. The fixture is adjusted to align the top elevation of the flat steel bar 2 with the top slab of the cast-in-place beam. The top elevation of the flat steel bar 2 is used as a reference to control the elevation of the cast-in-place beam during the subsequent pouring of the top slab concrete. After the concrete pour is completed but before it sets, the flat steel bar 2, along with the bolts 3 and clamping plate 1, is removed and recycled.

[0025] Specific implementation process:

[0026] 1. Determine the design elevation and layout of the cast-in-place beam bridge deck. Prepare the required base, adjustable fixtures, and flat steel, ensuring their quality and quantity meet the requirements.

[0027] 2. Place the base on the top plate of the cast-in-place beam according to the design requirements. The base is fixed by welding or adjustable support feet to ensure stable support and accurate positioning. The base spacing is 3 to 5 meters, which is determined by the weight of the scraping beam and the vertical stiffness of the flat steel 2.

[0028] 3. Install the adjustable fixture on the base. Pass bolt 3 through the fixing nut 4 and the hole in the base plate 5. Secure bolt 3 with the fixing nut 4. Ensure that the inverted U-shaped structure of the fixture can accurately secure the flat steel 2. The fixture elevation can be adjusted by rotating bolt 3 to meet the required bridge deck elevation.

[0029] 4. Use manual or modified mechanical means to adjust the height of the adjustable fixture to ensure it matches the elevation of the top plate of the cast-in-place beam. Lock the adjusted height to prevent elevation changes during the concrete pouring process. To ensure tightness, install a second movable nut at the bottom of the base plate 5 to reversely lock the bolt 3.

[0030] 5. Pour concrete based on the elevation control device to ensure that the concrete is evenly distributed and reaches the elevation and flatness required by the design.

[0031] 6. Before the concrete begins to set, remove the fixture and flat steel 2 from the concrete. Immediately clean the fixture and flat steel 2 to ensure their surfaces are clean so that they can be reused in the next construction.
