Description

Technical Field

[0001] The utility model relates to road construction, in particular to a concrete road surface free-cutting construction structure. Background Art

[0002] In the process of urban road concrete construction, due to the limitation of concrete strength age and site, it is impossible to continuously pour multiple slabs of concrete horizontally. When the road width is wide, it is necessary to carry out construction in sections, which seriously affects the construction period and requires multiple formwork. This not only makes it difficult to ensure the quality of cast-in-place concrete, but also makes the construction efficiency low. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned background technology and to provide a concrete pavement cutting-free construction structure, so as to solve the problem of continuous pouring of multiple concrete panels and improve the construction efficiency of the concrete pavement.

[0004] The utility model provides a concrete pavement cutting-free construction structure, comprising a concrete structure, wherein a middle partition plate arranged along the axial direction is provided at the central axis of the concrete structure, the middle partition plate is arranged in a vertical direction, and a base steel plate perpendicular to the middle partition plate is provided at the bottom of the middle partition plate, and the base steel plate is arranged along the axial direction of the concrete structure.

[0005] In the above technical solution, the middle partition includes a middle seam steel plate and plastic plates respectively connected to two sides of the middle seam steel plate.

[0006] In the above technical solution, the base steel plate is symmetrically arranged with the middle partition as the symmetry axis.

[0007] In the above technical solution, side steel plates are respectively arranged perpendicularly to the base steel plate on both sides, and the base steel plate and the side steel plates form an inverted "L"-shaped structure.

[0008] In the above technical solution, a plurality of holes are evenly distributed in the middle of the middle partition along the axial direction, and a connecting rib perpendicular to the middle partition is provided in each hole.

[0009] In the above technical solution, the thickness of the steel plate where the center seam steel plate contacts the connecting ribs is greater than the thickness of the steel plate at other positions of the center seam steel plate.

[0010] In the above technical solution, a grease layer is provided on the top of the middle partition.

[0011] The utility model concrete pavement cutting-free construction structure has the following beneficial effects:

[0012] 1. The middle partition is a one-time structure, which acts as a template during the concrete pouring process. The middle of the middle partition adopts a structure in which the middle seam steel plate is covered with plastic plates on both sides. The middle seam steel plate ensures the rigidity of the middle partition, and no lateral deformation will occur when the concrete is poured on both sides; the plastic plates on the outside not only strengthen the rigidity of the middle partition, but also provide space for the expansion and deformation of the concrete in the later stage, ensuring that the concrete will not be squeezed and damaged;

[0013] 2. The bottom of the middle partition is a base steel plate, which is symmetrically arranged on both sides. First, pour the concrete at the bottom to ensure the stability of the middle partition and prevent it from tilting or collapsing. At the same time, the two ends of the base steel plate are set in an inverted L shape, which plays the role of connecting the concrete slabs on both sides after the concrete pouring is completed;

[0014] 3. Reserve holes in the middle of the middle partition according to the diameter and spacing of the connecting reinforcement. Insert the connecting reinforcement into the middle partition before pouring concrete. At the same time, the steel plate in the connecting reinforcement area is appropriately thickened to ensure that the connecting reinforcement is stable. BRIEF DESCRIPTION OF THE DRAWINGS
