Abstract
Description
Technical Field
[0001] This utility model relates to a detachable support steel plate, and more particularly to a detachable support steel plate for temporarily restoring passage through trenches. Background Technology
[0002] Existing trenches require nighttime construction due to road closures, with traffic restored during the day. However, large vehicles travel on the highway, and simply laying steel plates across the trenches poses a significant safety hazard when large vehicles pass. Temporary traffic restoration primarily involves backfilling with earth and rock before laying the steel plates, or adding temporary supports before laying the steel plates. If backfilling is used, the earth and rock must be excavated before construction can resume, resulting in a long construction period and increased costs. If temporary supports are used, they need to be custom-made according to the trench depth, lacking versatility and requiring a robust foundation. This patent aims to provide a utility model of a detachable support steel plate that is easy to install and transport, and has wide applicability. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a detachable support steel plate that is easy to install, transport, and widely applicable.
[0004] In order to solve the technical problems existing in current construction, this utility model adopts the following technical solution:
[0005] The present invention provides a detachable support steel plate, including a horizontal steel plate for supporting the top of a trench. A row of semi-circular steel plates is respectively arranged on the front and rear sides of the bottom surface of the horizontal steel plate. A circular hole is opened in the center of each semi-circular steel plate. A support structure is respectively arranged on the left and right sides between any two adjacent rows of semi-circular steel plates.
[0006] Each of the aforementioned support structures includes a side edge that is pressed against the trench slope and a support plate whose top wall can be pressed against the bottom edge of a horizontal steel plate. The side edge of the support plate is connected to the side edge, and a circular hole is opened in the support plate. The support structure is fixedly connected to the horizontal steel plate by a horizontal axis passing through the circular hole and a circular hole in the semi-circular steel plate.
[0007] The beneficial effects of this utility model are:
[0008] (1) This device does not require any auxiliary devices or materials other than the device itself, and can be used immediately after assembly.
[0009] (2) The short side slope of the supporting steel plate of this device is set at 1:0.5, which is the maximum slope for slope excavation and can be used for all trench excavation. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0015] As shown in the attached diagram, this utility model discloses a detachable support steel plate, comprising a horizontal steel plate 1 for supporting the top of a trench. A row of semi-circular steel plates 4 is respectively arranged on the front and rear sides of the bottom surface of the horizontal steel plate 1. Preferably, multiple rows of semi-circular steel plates are arranged between the two rows of semi-circular steel plates on the front and rear sides. A circular hole is formed in the center of each semi-circular steel plate 4. A support structure 2 is respectively arranged on the left and right sides between any two adjacent rows of semi-circular steel plates. The position of the support structure can be selected and determined according to the needs of on-site support.
[0016] Each of the aforementioned support structures includes a side edge that presses against the trench slope and a support plate whose top wall can press against the bottom edge of a horizontal steel plate. The side edge of the support plate is connected to the side edge, and a circular hole is formed in the support plate. The support structure is fixedly connected to the horizontal steel plate via a horizontal axis 3 passing through the circular hole and the circular hole in the semi-circular steel plate. Preferably, the support structure is a triangular structure, and the support plate is the two side wings of the triangular structure. The part where the two side wings are connected is the side edge. To save materials, the support plate can be a hollow structure. The triangular structure increases the contact area with the slope, providing a more stable force transmission effect. The slope of the side edge (the ratio of the vertical height of the side edge to the horizontal projection width of the side edge) can be set at 1:0.5.
[0017] The method of using this device is as follows:
[0018] After the trench is excavated and sloped, a step is left at the top. After transporting the horizontal steel plate 1 to the site, a semi-circular steel plate 4 with holes is welded to the bottom of the horizontal steel plate 1. The processed support structure is arranged at the bottom of the steel plate 1. The horizontal shaft 3 is passed through the holes on the semi-circular steel plate 4 and the round holes on the support structure for fixation. After fixation, the horizontal steel plate 1 is hoisted and placed above the trench. After placement, a large vehicle is used to apply pressure to the steel plate so that the hypotenuse triangular steel plate of the support steel plate 2 is embedded in the slope, thus completing the fixation.
[0019] The above-described specific embodiments are merely illustrative and not restrictive. Those skilled in the art can make many modifications under the guidance of this utility model without departing from the spirit and scope of the claims, and these modifications are all protected by this utility model.
