Description

Technical Field

[0001] The utility model relates to a cover plate for a construction site opening, in particular to an embedded telescopic cover plate component, belonging to the technical field of building construction. Background Art

[0002] In the field of construction, openings, pipe wells, etc., as well as necessary retentions due to engineering and process needs, may cause people and objects to be in danger of falling or other injuries that endanger personal safety. Safety protection facilities must be set up in accordance with the requirements of relevant safety specifications and regulations. Foundation holes are an indispensable process in the construction process. The size and position of the holes are different, and the functions are also different. After the openings are set, necessary finished product protection and safety protection should be carried out to prevent the objects above from falling and causing harm to the lower part. After the traditional cover is placed, it cannot be fixed. Sitting on the opening, it will also cause other injuries such as tripping, falling, etc. After the traditional cover is covered, it is impossible to understand the situation below and it needs to be moved before checking. The need to move it before checking will increase the risk factor and fail to play a protective role. The openings are of different sizes and shapes, resulting in an increase in the number of covers used, a waste of manpower costs, and functional ventilation, fire protection, and drainage channels are blocked. The site is also in urgent need of a tool that can be adjusted according to the size of the opening without affecting other functions such as functional ventilation and drainage, so as to better play a safety protection role.

[0017] The utility model is further explained and illustrated below in conjunction with the accompanying drawings:

[0018] For example, see Figure 1-Figure 2A built-in telescopic cover assembly comprises a first angle plate 1, a second angle plate 2, a positioning sleeve 5 and a telescopic rod 7. The first angle plate 1 and the second angle plate 2 are symmetrically distributed and are respectively arranged on steps B of the inner wall of a construction opening A. At least two positioning sleeves 5 are arranged at intervals on the inner wall of the first angle plate 1. A telescopic rod 7 is inserted in the positioning sleeve 5. The outer end of the telescopic rod 7 is fixedly connected to the inner wall of the second angle plate 2. A support frame 8 is arranged above the construction opening A. Support legs are respectively arranged at the four corners of the bottom of the support frame 8. Rollers 3 are arranged at the bottom of the legs. A displacement plate 9 is slidably connected to the support frame 8, and a pull rope assembly 10 is arranged on the displacement plate 9.

[0019] A connecting plate 6 is arranged on the top of the positioning sleeve 5 .

[0020] A first handle 4 is provided at the center of the top of the first angle plate 1 and the top of the second angle plate 2, respectively, and a roller 3 is provided on the bottom surface of the inner wall of the first angle plate 1 and the inner wall of the second angle plate 2, respectively.

[0021] The pull rope assembly 10 consists of a support plate 902, a winding wheel 903 and a second handle 904. A rectangular through hole 901 is dug in the middle of the displacement plate 9, and support plates 902 are respectively arranged on both sides above the rectangular through hole 901. The winding wheel 903 is rotatably connected between the two support plates 902, and the second handle 904 is rotatably connected to the outside of the support plate 902. The inner end of the second handle 904 is fixedly connected to the winding wheel 903, a rope is wound on the winding wheel 903, and a pull hook 11 is connected to the bottom of the rope.

[0022] There are two displacement plates 9.

[0023] The bottoms of the first angle plate 1 and the second angle plate 2 are respectively located below the bottom of the roller 3 .

[0024] In the above description, the bottoms of the first angle plate and the second angle plate extend into the stepped interior of the construction opening respectively, that is, the bottoms of the two angle plates are located below the roller.

[0025] In the above description, a connecting plate is provided between the tops of adjacent positioning sleeves.

[0026] In the above description, the pull rope on the winding wheel passes through the rectangular through hole 901 and extends into the construction opening.

[0027] In the above description, the support frame spans above the construction opening, and the support frame can move horizontally above the construction opening.

[0028] In the above description, the first angle plate and the second angle plate are two identical right-angle plates.

[0029] Working principle:

[0030] When using, choose a few telescopic frames (i.e. Figure 2 The telescopic frame is lowered by using the pull rope assembly on the support frame. When the telescopic frame is not used at the construction opening, the pull rope assembly is also used to take it away.

[0031] The device is used for construction work on the edge of pile holes, manholes, trenches and pipe holes with a depth of 2m or more, which is called hole opening work. After the hole opening is set, necessary product protection and safety protection should be carried out to prevent people from falling into the hole, and at the same time prevent objects from falling from above from causing harm to the lower part. For the protection of hole opening work, a stable cover plate must be set. This cover plate can be telescopically adjusted in an embedded manner according to different sizes of holes without affecting other functional requirements such as ventilation and fire protection to play a safety protection role. The situation below the hole can also be visually checked through the interval between the cover plate materials (without moving the cover plate) to understand the situation inside the hole. A connecting plate, i.e. flat steel, is welded on the telescopic positioning sleeve to enhance the stability.

[0032] The utility model arranges rollers at the bottom of the first angle plate and the second angle plate to facilitate the horizontal movement of the device along the steps of the construction opening. By arranging a telescopic rod and a positioning sleeve between the two angle plates, it can be freely moved according to the size of the construction opening. At the same time, the positioning sleeve and the telescopic rod are distributed at intervals, which does not affect the staff's observation of the construction situation in the construction opening at any time. The utility model is easy to use and simple to operate.
