Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a floor slab casting vibration bridge bracket. Background Art
[0002] When pouring concrete, bubbles must be removed and tamped to make the concrete dense and combined, and eliminate the honeycomb and pockmarked surface of the concrete, so as to improve the strength of the concrete and ensure the quality of the concrete components. The above process of removing bubbles and tamping the concrete is called concrete vibration, and the concrete vibrator is a tool used to compact the concrete.
[0003] When vibrating floor slab concrete, a surface vibrator is usually used to ensure the flatness of the concrete. However, since workers need to drag the vibrator to move it during vibration, it is inevitable that the vibrator will tilt to one side during the dragging process. At this time, the concrete thickness at a certain position will become smaller, the floor surface after solidification will not be flat enough, and the floor thickness and the thickness of the steel bar protective layer cannot meet the requirements. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a floor slab casting vibration bridge bracket, which can make the vibrator move smoothly without tilting during vibration, and can ensure the flatness of the floor and ensure that the thickness of the floor slab and the thickness of the steel bar protective layer meet the requirements.
[0005] In order to solve the above technical problems, the technical solutions adopted are as follows:
[0006] A floor casting vibration bridge support, characterized in that it includes multiple steel pipes and multiple steel pipe supports, one steel pipe corresponds to at least two steel pipe supports; the steel pipe support includes a fixed base and a steel pipe erection seat, the upper end of the fixed base is provided with a first connecting piece, the lower end of the steel pipe erection seat is provided with a second connecting piece matching the first connecting piece, the steel pipe erection seat is installed on the fixed base through the second connecting piece and the first connecting piece, and the upper end of the steel pipe erection seat is provided with a steel pipe erection groove for placing the steel pipe.
[0007] Before pouring concrete on the floor slab, a plurality of steel pipe brackets are first arranged in an array on the formwork. When setting, the fixed base is first fixed on the formwork, and then the second connecting piece and the first connecting piece are installed on the fixed base according to the thickness requirements of the concrete, and the steel pipe mounting seat is placed at a suitable height; after each steel pipe bracket is set, a steel pipe is mounted on the steel pipe bracket (the steel pipe is in the steel pipe mounting groove and placed in the horizontal direction, and one steel pipe is supported by at least two steel pipe brackets), and the distance between the upper side of the steel pipe and the formwork is equal to the thickness of the required concrete layer, thereby completing the installation of the floor slab pouring vibration bridge bracket. When vibrating, the two ends of the vibrating bottom plate of the vibrator span across two adjacent steel pipes. As the workers drag, the steel pipe can always limit the vibrator, ensuring that the height of each position is uniform during the vibration process, so that the floor surface is flat after the concrete solidifies, and ensuring that the floor thickness and the thickness of the steel bar protective layer meet the requirements. After the concrete layer is vibrated, the steel pipe can be removed and reused (the pit left after the steel pipe is removed can be filled with concrete mortar), and the steel pipe support is buried in the concrete layer.
[0008] In a preferred solution, the first connecting member is a nut, and the second connecting member is a stud extending up and down, and the stud is threadedly connected to the nut. The threaded connection can fine-tune the height of the steel pipe mounting seat, making it easier to ensure uniform height at each position.
[0009] In a further preferred embodiment, the fixed base includes a base frame and a plurality of vertical poles, the lower ends of the vertical poles are fixedly connected to the base frame, and the upper ends of the vertical poles are connected to the outer periphery of the nut and arranged along the circumference of the nut. The vertical poles surround the nut and leave a space below the nut for the stud to extend into. The vertical poles are made of steel bars.
[0010] In a further preferred embodiment, the base frame is X-shaped.
[0011] In a further preferred embodiment, the base frame includes two second steel bars bent into an L shape, and the bent parts of the two second steel bars are connected (for example, welded) to form an X-shaped base frame. The base frame can be fixed to the template by using multiple iron nails to nail the template, and each iron nail is located on the side of the second steel bar, so that the base frame is first limited in the horizontal direction, and then the nail heads of the iron nails are pressed down in the direction of the second steel bar to press the second steel bar, thereby fixing the base frame. The base frame can also be fixed to the template by using multiple semicircular clamps to clamp the second steel bars respectively and then lock them on the template.
[0012] In a further preferred embodiment, the lower end of the vertical rod is welded to the base frame, and the upper end of the vertical rod is welded to the outer periphery of the nut.
[0013] In a further preferred embodiment, the steel pipe mounting seat is made of semicircular round steel, which is high at both ends and low in the middle, and the middle part of the semicircular round steel is welded to the upper end of the stud.
[0014] In another preferred embodiment, the first connecting member is a stud extending upward and downward, and the second connecting member is a nut, and the stud and the nut are threadedly connected.
[0015] The nuts, studs, uprights, steel bars and round steels are all common construction materials at construction sites, and are all fixed and connected by welding. Therefore, the floor slab casting vibration bridge bracket is easy to obtain and manufacture, and has a low manufacturing cost.
[0016] The beneficial effect of the utility model is that the floor slab casting vibration bridge bracket can make the vibrator move smoothly without tilting during vibration, which can not only ensure the flatness of the floor, but also ensure that the floor slab thickness and the steel bar protection layer thickness meet the requirements.
