[0002] The existing composite floor is an assembled integral floor composed of prefabricated panels and cast-in-place reinforced concrete layers. The composite floor has good integrity, and the upper and lower surfaces of the panels are flat, which is convenient for finishing layer decoration. It is suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity.

[0003] At present, there is an existing two-way composite slab bottom plate with close joint connection (such as patent number: CN209723341U), which discloses a two-way composite slab bottom plate with close joint connection, wherein the two-way composite slab bottom plate comprises 2 to 3 single plates that need to be connected with close joint connection, and a post-cast groove is left at a certain interval at the joint of the single plates, and the connecting steel bars are exposed in the post-cast groove, and the ends of the connecting steel bars are threaded; the connecting steel bars between the two connected single plates are connected by a steel bar connector. The two-way composite slab bottom plate is manufactured in a factory, transported to the site and hoisted, and the steel bar connector is inserted into the steel bar on one side of the seam, and the other bottom plate to be connected is hoisted to align the grooves of the two bottom plates, and the steel bar connector is inserted into the steel bar to be connected on the other side, and the three connecting steel bars are tightened with nuts to complete the steel bar connection. After the steel bars are connected, the nuts can also be used to apply tension to the steel bars, and this tension will generate pre-stress in the concrete at the joint, thereby improving the performance of the composite slab.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following problems: when the first single board and the second single board were connected, the corresponding post-cast grooves needed to be aligned one by one, so the staff needed to constantly adjust the position of the first single board or the second single board, which reduced the connection efficiency of the first single board and the second single board.

[0024] The embodiment of the present application provides a close-jointed connection node for edge-laminated floor slabs, thereby effectively solving the technical problem that when the first single board 1 and the second single board 2 are connected, the corresponding post-cast grooves 7 need to be aligned one by one, so the staff needs to constantly adjust the position of the first single board 1 or the second single board 2, thereby reducing the connection efficiency of the first single board 1 and the second single board 2.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The technical solution in the embodiment of the present application effectively solves the technical problem that when the first single board 1 and the second single board 2 are connected, the corresponding post-casting grooves 7 need to be aligned one by one, so the staff needs to constantly adjust the position of the first single board 1 or the second single board 2, which reduces the connection efficiency of the first single board 1 and the second single board 2. The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a close-jointed connection node for edge-laminated floor slabs, which comprises a first single board 1, a second single board 2 is placed outside the first single board 1, slots 3 are provided at both ends of the first single board 1, connecting mechanisms are provided at both ends of the second single board 2, each connecting mechanism comprises a connecting shaft 4, an external thread 5 and an insert block 6, the connecting shaft 4 is provided on the outside of the second single board 2, the external thread 5 is provided on the outside of the connecting shaft 4, and the insert block 6 is threadedly connected to the outside of the external thread 5.

[0028] By setting the slot 3 and cooperating with the plug block 6, when the first single board 1 is connected to the second single board 2, the second single board 2 is lifted on site so that the second single board 2 is close to the first single board 1 placed on the ground. When the second single board 2 is close to the first single board 1, the staff can adjust the position of the second single board 2 so that the plug block 6 is fully inserted into the inside of the slot 3. At this time, the first single board 1 and the second single board 2 are completely fitted together. When the first single board 1 and the second single board 2 are connected, the corresponding post-cast grooves 7 need to be aligned one by one. Therefore, the staff can align the first single board 1 with the second single board 2 without observing and adjusting the position of the first single board 1 or the second single board 2, thereby preventing the connection efficiency of the first single board 1 and the second single board 2 from being reduced.

[0029] Both ends of the second single board 2 are provided with grooves 7, and the connecting shaft 4 is fixedly connected to the inside of the groove 7. After the first single board 1 and the second single board 2 are installed, concrete is used to pour the inside of the groove 7 to facilitate the stability of the connection between the connecting shaft 4 and the second single board 2. Both ends of each plug block 6 are provided with connecting grooves 8, and the connecting grooves 8 are located on a side of the plug block 6 close to the groove 7. Concrete enters the groove 7 and flows into the connecting groove 8 for pouring to facilitate the stability of the connection between the plug block 6 and the second single board 2.

[0030] A mounting hole 9 is provided on the outside of each plug block 6, and the connecting groove 8 is communicated with the mounting hole 9. A mounting cylinder 10 is clamped inside each mounting hole 9. An internal thread 11 is provided on the inner side of the mounting cylinder 10. The plug block 6 is threadedly connected to the outside of the external thread 5 through the internal thread 11, which is convenient for the replacement of the plug block 6. Limiting plates 12 are fixedly installed on both ends of the outer side of each mounting cylinder 10, and limiting grooves 13 are provided on both ends of the inside of each mounting hole 9. The limiting plate 12 is slidably connected to the inside of the limiting groove 13 to limit the rotation of the mounting cylinder 10 inside the mounting hole 9. A circular groove 14 is provided on the side of each plug block 6 away from the groove 7. A circular plate 15 is slidably connected to the inside of each circular groove 14. The connecting shaft 4 is slidably connected to the inner side of the circular plate 15. The circular groove 14 is communicated with the mounting hole 9, and the circular plate 15 is fixedly installed on the mounting cylinder 10, to avoid the connection between the installation tube 10 and the installation hole 9 being released. By setting the installation hole 9 and cooperating with the installation tube 10, when the plug block 6 is damaged during the transportation of the second single board 2, the plug block 6 is rotated to release the connection between the external thread 5 and the internal thread 11. At this time, the installation tube 10 is pushed to release the connection between the installation tube 10 and the installation hole 9. At this time, the plug block 6 is disassembled. At this time, the plug block 6 is damaged. When installing a new plug block 6, the installation tube 10 is inserted into the inside of the installation hole 9. At this time, the limit plate 12 enters the inside of the limit groove 13 to limit the rotation of the installation tube 10 in the installation hole 9. At this time, the plug block 6 is threadedly connected to the outside of the external thread 5 through the internal thread 11 until the plug block 6 is fitted with the outside of the second single board 2. At this time, the plug block 6 is installed. The detachable plug block 6 is convenient for replacing the plug block 6 according to the working conditions.

[0031] Working principle:

[0032] The first step is to insert the block 6, insert the installation tube 10 into the installation hole 9, and then the limit plate 12 enters the limit groove 13 to limit the rotation of the installation tube 10 in the installation hole 9. At this time, the block 6 is threadedly connected to the outside of the external thread 5 through the internal thread 11 until the block 6 fits with the outside of the second single board 2. At this time, the block 6 is installed;

[0033] In the second step, by setting the slot 3 and matching the plug block 6, when the first single board 1 is connected to the second single board 2, the second single board 2 is lifted on site so that the second single board 2 is close to the first single board 1 placed on the ground. When the second single board 2 is close to the first single board 1, the staff can adjust the position of the second single board 2 so that the plug block 6 is fully inserted into the slot 3. At this time, the first single board 1 and the second single board 2 are fully fitted. When the first single board 1 and the second single board 2 are connected, the corresponding post-casting grooves 7 need to be aligned one by one. Therefore, the staff does not need to observe and adjust the position of the first single board 1 or the second single board 2 to align the first single board 1 with the second single board 2, thereby preventing the connection efficiency of the first single board 1 and the second single board 2 from being reduced.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
