Description

Technical Field

[0001] The utility model relates to a leisure plank road, in particular to a guardrail for the leisure plank road with a prefabricated assembled concrete structure. Background Art

[0002] Currently, Chinese patent publication number CN210657935U discloses a shock-absorbing concrete imitation wood plank walkway, comprising a keel support and guardrails. The upper end surface of the keel support is lined with concrete imitation wood planks, and column feet are fixed to the bottom side of the keel support by mortise and tenon joints. The bottom end of the guardrail is fixedly connected to the keel support. However, in this imitation wood plank walkway, the guardrail is fixedly connected to the keel support and is integrally formed by pouring concrete. This makes it difficult to remove and replace the guardrail if it becomes damaged. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a guardrail for a leisure plank road with a prefabricated assembled concrete structure, which has the advantage of being able to be easily dismantled and replaced when damaged.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a guardrail for a leisure plank road of a prefabricated assembled concrete structure, comprising two guardrail posts symmetrically arranged on the left and right, and a guardrail body arranged between the two guardrail posts, the guardrail posts comprising a post body, a connecting sleeve arranged below the post body, and a decorative block arranged above the post body, a mounting hole being provided through the center of the post body, the connecting sleeve being buried in the keel bracket of the imitation wood plank road, and an internal thread being provided in the connecting sleeve, a connecting column being provided at the lower end of the decorative block, the connecting column passing through the mounting hole, and an external thread being provided at the lower end of the connecting column, the external thread being used to be screwed together and fixed with the internal thread.

[0005] According to the above technical solution, when the above guardrail needs to be installed, the first step is to bury the connecting sleeve into the keel bracket of the leisure plank road so that the opening of the connecting sleeve is vertically upward; the second step is to move the column body to the top of the connecting sleeve so that the mounting hole is connected with the inner hole of the connecting sleeve; the third step is to move the decorative block to the top of the column body so that the connecting column passes through the mounting hole; the fourth step is to rotate the decorative block so that the connecting column is threadedly connected to the connecting sleeve until the lower end of the decorative block is tightly pressed against the column body. At this time, the decorative block presses the column body to the upper end of the keel bracket of the leisure plank road. When it is necessary to remove and replace a damaged guardrail, the first step is to rotate the decorative block in the opposite direction so that the connecting column is separated from the connecting sleeve; the second step is to pull the column body upward to remove the above guardrail from the keel bracket of the leisure plank road. In summary, the above guardrail has the advantage that it can be removed and replaced more conveniently when damaged.

[0006] Preferably, a plurality of plug-in columns are provided at the lower end of the column body, and the plurality of plug-in columns are evenly distributed along the circumference of the mounting hole for being plugged and fixed in the keel bracket of the imitation wooden plank road.

[0007] Through the above technical solution, a plug-in column is installed at the lower end of the column body for plugging and fixing it in the keel bracket of the imitation wooden plank road. This not only improves the connection stability between the column body and the keel bracket, but also can be used to limit the installation angle of the column body, thereby improving the neatness of the above-mentioned guardrail after installation.

[0008] Preferably, the guardrail body includes two guardrail cross bars symmetrically arranged in an upper and lower direction, and a plurality of guardrail blocking bars arranged between the two guardrail cross bars, and the plurality of guardrail blocking bars are evenly distributed along the length direction of the guardrail cross bars.

[0009] Through the above technical solution, the guardrail composed of two guardrail cross bars and a plurality of guardrail bars can achieve a better protective effect.

[0010] Preferably, a connecting opening is provided at a position opposite to the guardrail cross bar on the side wall of the column body, the connecting opening is communicated with the mounting hole, a sliding groove is provided at the end of the guardrail cross bar, a connecting buckle is slidably connected in the sliding groove, the connecting buckle passes through the connecting opening and extends into the mounting hole, the connecting column passes through the inner hole of the connecting buckle, and the connecting column is tightly pressed against the inner wall of the connecting buckle.

[0011] Through the above technical solution, after separating the guardrail from the keel bracket, if you want to remove the guardrail body from between the two guardrail posts, you need to first pull the decorative block upwards to disengage the connecting column from the mounting hole, thereby releasing the restriction of the connecting column on the connecting buckle. After that, you need to pull the column body away from the guardrail cross bar, or push the connecting buckle toward the inside of the sliding groove to separate the column body from the connecting buckle, and then the guardrail body can be removed.

[0012] Preferably, a limiting groove is provided at the inner groove wall of the sliding groove, the side of the limiting groove close to the column body is the extended side, and the side of the limiting groove away from the column body is the retracted side. A limiting protrusion is provided at the outer wall of the connecting buckle, and the limiting protrusion is slidably connected in the limiting groove. When the limiting protrusion conflicts with the extended side, the connecting buckle protrudes out of the sliding groove, and the inner wall of the connecting buckle can just conflict with the connecting column passing through the mounting hole. When the limiting protrusion conflicts with the retracted side, the connecting buckle is completely received in the sliding groove.

[0013] Through the above technical solution, the limiting groove and the limiting protrusion cooperate with each other to control the sliding stroke of the connecting buckle.

[0014] Preferably, a positioning groove is provided at a position where the side wall of the guardrail crossbar is opposite to the guardrail stop bar, and a positioning block is provided at the end of the guardrail stop bar, and the positioning block is inserted and fixed in the corresponding positioning groove.

[0015] Through the above technical solution, the positioning groove and the positioning block cooperate with each other to detachably connect the guardrail cross bar and the guardrail stop bar, so that damaged accessories can be replaced as needed to reduce waste. BRIEF DESCRIPTION OF THE DRAWINGS
