[0027] Now the content of the present utility model will be described with reference to exemplary embodiments. It should be understood that the described embodiments are only for enabling those of ordinary skill in the art to better understand and thus implement the content of the present utility model, rather than implying any limitation to the scope of the present utility model.

[0028] As used herein, the term "comprising" and its variants are to be construed as open-ended terms meaning "including but not limited to". The term "based on" is to be construed as "at least partially based on". The terms "an embodiment" and "one embodiment" are to be construed as "at least one embodiment".

[0029] As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in the present embodiment, the anti-offset combined box cover for a prefabricated hollow ribbed floor slab includes a box body 1, a first box cover 2, and a second box cover 14. Two groups of T-shaped limit sliding bars 3 are symmetrically and fixedly connected to the top of the box body 1. Two groups of limit sliding grooves 4 corresponding to each T-shaped limit sliding bar 3 are symmetrically formed at the bottoms of the first box cover 2 and the second box cover 14. The T-shaped limit sliding bars 3 are slidably inserted into the interiors of the limit sliding grooves 4. Among them, a clamping component 5 is arranged on the top of the first box cover 2, and a locking component 6 that cooperates with the clamping component 5 to position the two box covers 2 is arranged on the top of the second box cover 2. The first box cover 2 and the second box cover 14 are both made of hollow steel plates, and cross reinforcing ribs 12 are arranged in the inner cavities of the first box cover 2 and the second box cover 14. The hollow steel plate is lighter than a solid steel plate or reinforced concrete, which helps to reduce the weight of the entire box cover structure, and thus reduces the inertial force under the action of the foundation load.

[0030] Furthermore, in the present embodiment, after the two box covers 2 are combined, the first box cover 2 and the second box cover 14 are completely locked by the cooperation of the clamping component 5 and the locking component 6, so that the first box cover 2 and the second box cover 14 are firmly covered on the top of the box body 1, avoiding the situation that the first box cover 2 and the second box cover 14 shake or even displace when subjected to external forces or vibrations, thereby ensuring the stability of the overall structure of the ribbed floor slab. In addition, the box cover is set to two groups (i.e., the first box cover 2 and the second box cover 14), and then a prefabricated design is adopted to allow the box cover to be fabricated in sections during the manufacturing process, thereby reducing the size and weight of a single component; this helps to simplify the transportation process, reduce transportation costs, and facilitate on-site installation. The prefabricated box cover can also be flexibly adjusted in size and shape according to actual needs to adapt to different floor slab structures.

[0031] Furthermore, in the present embodiment, the clamping component 5 includes a fixing plate 501 and an inserting plate 502. The fixing plate 501 is fixedly installed on the top of the first box cover 2, and the inserting plate 502 is fixedly connected to one side side wall of the fixing plate 501;

[0032] The locking assembly 6 includes a positioning shell 601 which is fixedly installed on the top of the second box cover 14. A receiving cavity 602 adapted to the insertion plate 502 is reserved on one side of the positioning shell 601. The insertion plate 502 is inserted into the interior of the receiving cavity 602 to achieve the preliminary positioning of the first box cover 2 and the second box cover 14.

[0033] Further, in this embodiment, the locking assembly 6 further includes a plurality of fixed sleeves 7 which are arranged at intervals. A positioning rod 8 is slidably inserted into each of the fixed sleeves 7. The bottom end of each positioning rod 8 penetrates through the positioning shell 601 and is inserted into the interior of the insertion plate 502. The top of each positioning rod 8 is fixedly connected to a pulling plate 9.

[0034] Further, in this embodiment, the locking assembly 6 further includes a plurality of telescopic springs 10. The top end of each telescopic spring 10 is fixedly connected to the bottom of the pulling plate 9. The bottom end of each telescopic spring 10 is fixedly connected to the top end of each fixed sleeve 7 respectively. Each telescopic spring 10 is movably sleeved on the outer wall of each positioning rod 8. When it is necessary to lock and position the first box cover 2 and the second box cover 14, the pulling plate 9 can be lifted upward first. At this time, the telescopic spring 10 is in a stretched state. Then, the push-pull handle 13 is pushed to insert the insertion plate 502 into the interior of the receiving cavity 602. When the insertion plate 502 is completely inserted into the receiving cavity 602, the pulling plate 9 is released at this time, and the positioning rod 8 is stably inserted into the interior of the insertion plate 502 by the pulling force of the telescopic spring 10, so as to achieve the effect of locking and positioning the first box cover 2 and the second box cover 14.

[0035] Further, in this embodiment, the material of the box body 1 is set to be made of concrete, and several groups of steel bars 11 are arranged in each side wall of the box body 1. The box body 1 is made of concrete material, which has good compressive performance and durability. According to needs, materials such as ordinary concrete, lightweight concrete or high-performance concrete can be selected;

[0036] Push-pull handles 13 are fixedly connected to the tops of the two groups of box covers 2, and the two groups of push-pull handles 13 are symmetrically arranged.

[0037] According to the above scheme of the present invention, the present invention can solve the problems in the prior art that the box cover adopts an integral structure, is heavy and bulky, is not conducive to transportation, and has a heavy weight and is not conducive to on-site installation; it can also solve the problems in the prior art that only the top of the box body is clamped into the groove and only limited by the groove, and the connection between the box cover and the box body may not be firm enough, and the box cover may shake or shift when subjected to external forces or vibrations, affecting the stability of the overall structure.

[0038] In the present utility model, by setting the box cover into two groups and adopting a modular design, the box cover is allowed to be fabricated in sections during the manufacturing process, thereby reducing the size and weight of a single component; this helps to simplify the transportation process, reduce transportation costs, and facilitate on-site installation. In addition, the hollow steel plate is lighter than the solid steel plate or reinforced concrete, which helps to reduce the weight of the entire box cover structure.

[0039] In the present utility model, by setting the T-shaped limit slide bar and the limit slide groove to cooperate with each other, the two groups of box covers can be inserted into the inside of the limit slide groove with the T-shaped limit slide bar from one side of the upper surface of the box body, thereby limiting the two groups of box covers. In addition, after the two groups of box covers are combined, by setting the clamping component and the locking component to cooperate with each other, the two groups of box covers can be completely locked, so that the two groups of box covers are firmly covered on the top of the box body, avoiding the situation that the box covers shake or even displace when subjected to external forces or vibrations, thereby ensuring the stability of the overall structure of the ribbed floor slab.

[0040] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and details without departing from the scope defined by the claims of the present utility model.
