A roadway roof

Abstract

This utility model discloses a roadway roof slab, relating to the field of roadway roof slab technology. Its key technical features include a roof slab with multiple supporting rotating plates rotatably installed at both ends in the width direction. These supporting rotating plates are evenly distributed along the length direction of the roof slab. Multiple limiting baffles are fixedly installed on the lower surface of the roof slab, with each supporting rotating plate corresponding to one limiting baffle. When the supporting rotating plate is in a vertical state, one side of the supporting rotating plate is in contact with the limiting baffle, and this side is the side away from the roadway. When the multiple supporting rotating plates are subjected to force, they are blocked by the limiting baffles and the roadway sidewalls, giving the roof slab strong support capabilities and preventing easy collapse. This provides high stability to the roadway supported by the roof slab and improves construction safety.

[0015] The following combination Figures 1 to 2 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0016] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] Please combine Figures 1 to 2 As shown, this utility model provides a roadway roof slab. Multiple supporting rotating plates 3 are rotatably installed at both ends of the roof slab 1 in the width direction. The multiple supporting rotating plates 3 are evenly distributed in the length direction of the roof slab 1. Multiple limiting baffles 2 are fixedly installed on the lower surface of the roof slab 1. Each supporting rotating plate 3 corresponds to one limiting baffle 2. When the supporting rotating plate 3 is in a vertical state, one side of the supporting rotating plate 3 is in contact with the limiting baffle 2. One side of the supporting rotating plate 3 is the side away from the roadway.

[0019] The bottom ends of multiple support rotating plates 3 are fixed to the bottom of the roadway, and the roof plate 1 is fixedly installed on the top of the roadway. When supporting the roadway, the multiple support rotating plates 3 support both ends of the roof plate 1 in the width direction. The support rotating plates 3 are located between the limiting baffle 2 and the roadway sidewall. When the roof plate 1 is subjected to greater pressure, the roof plate 1 is prone to collapse. However, under the action of the multiple support rotating plates 3, after being subjected to force, the multiple support rotating plates 3 are blocked by the limiting baffle 2 and the roadway sidewall, so that the multiple support rotating plates 3 have a strong support capacity for the roof plate 1, so that the roof plate 1 will not collapse easily. This makes the roadway supported by the roof plate 1 have high stability and can further improve the safety of construction.

[0020] To increase the stability of the bottom ends of multiple support plates 3, a reinforcing plate 4 is provided between the bottom ends of two support plates 3 located at both ends of the width direction of the roof plate 1. A connecting protrusion 5 is fixedly installed at both ends of the length direction of the reinforcing plate 4. The support plates 3 and the connecting protrusion 5 are fixedly connected by anchor bolts 6. The anchor bolts 6 are inserted into the sidewall of the roadway. Concrete can be poured on each reinforcing plate 4 to firmly fix the support plates 3 at the bottom end of the roadway, which can further improve the support capacity of the roof plate 1 for the roadway.

[0021] Finally, it should be noted that an upper combined plate 8 is fixedly installed at one end of the roof plate 1 along its length, and a lower combined plate 7 is fixedly installed at the other end of the roof plate 1 along its length. After the roof plate 1 is fixed to the inner top of the roadway, the upper combined plate 8 on the adjacent roof plate 1 is inserted between the lower combined plate 7 and the inner top of the roadway. When installing the roof plate 1, only the end of the roof plate 1 with the lower combined plate 7 needs to be provided with support, which can reduce the difficulty of fixing the roof plate 1. In addition, the multiple roof plates 1 in the roadway have a mutual replication and support function, which is conducive to improving the overall support capacity of the roadway and further improving the stability of the roadway support.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
