[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0036] Example:

[0037] like Figures 1-6 As shown, a prefabricated composite floor slab includes a slab body 100 and a tie member 200;

[0038] The plate 100 has two opposite ends, one end of which is configured as a storage end with a storage hole 101, and the other end of which is configured as a connecting end with a snap-fit ​​rod 102; correspondingly, the plate 100 is provided with a snap-fit ​​hole 103 adapted to the snap-fit ​​rod 102.

[0039] The pulling member 200 is used to pull the clamping rod 102, so that the clamping rod 102 is extended out of the plate body 100;

[0040] Correspondingly, when two adjacent plate bodies 100 are connected, the clamping rod 102 of one of the plate bodies 100 is inserted into the receiving hole 101 of the other plate body 100 through the pulling member 200.

[0041] In the assembled composite floor slab, the structure of the plate body 100 is improved, and the receiving hole 101 and the clamping rod 102 are arranged. When two adjacent plate bodies 100 are connected, the clamping rod 102 can be pulled into the receiving hole 101 without manual alignment, which can improve the alignment efficiency and ensure the alignment quality. At this time, the clamping rod 102 also plays a connecting role, which improves the reliability of the connection between the two adjacent plate bodies 100.

[0042] Meanwhile, the pulling member 200 is arranged, which provides power for the movement of the clamping rod 102, so as to improve the convenience of pulling the clamping rod 102 and improve the efficiency of pulling.

[0043] It is worth noting that, as shown in Figure 1 The two ends of the plate body 100 are respectively provided with a plurality of receiving holes 101 and a plurality of clamping rods 102, so as to effectively increase the number of connection points between the two adjacent plate bodies 100, which can improve the accuracy of alignment and ensure the strength of connection. Preferably, among the plurality of receiving holes 101 and the plurality of clamping rods 102, the receiving holes 101 and the clamping rods 102 are arranged one by one.

[0044] In work, the workers place two plate bodies 100 relative to each other and roughly align them, and pull a plurality of clamping rods 102 out of the receiving holes 101 through the pulling member 200. If the clamping rod 102 is successfully inserted into the corresponding receiving hole 101, then move one of the plate bodies 100 until the end portions of the two plate bodies 100 are close to each other. If the clamping rod 102 is stuck or blocked, the worker moves the position of one of the plate bodies 100, and then pulls the clamping rod 102 until the clamping rod 102 is successfully inserted into the corresponding receiving hole 101, and then moves one of the plate bodies 100 until the end portions of the two plate bodies 100 are close to each other.

[0045] In a possible implementation, the top surface of the plate body 100 is provided with a first hole body 104 and a second hole body 105. The first hole body 104 is located at the end portion of the plate body 100 and communicates with the receiving hole 101 downward. The second hole body 105 extends downward and communicates with the clamping hole 103, and the connection between the second hole body 105 and the clamping hole 103 is close to the hole bottom surface of the clamping hole 103.

[0046] Based on the above design scheme, when two adjacent plate bodies 100 are connected, in order to more conveniently observe the coaxiality between the clamping rod 102 and the receiving hole 101, the first hole body 104 is arranged to facilitate observation by the staff, thereby reducing the number of times of moving the plate body 100 and improving the connection efficiency.

[0047] When two adjacent plate bodies 100 are connected, that is, the clamping rod 102 of one plate body is inserted into the receiving hole 101 of the other plate body, a cavity will appear in the hole bottom region of the clamping hole 103, so the second hole body 105 is arranged to communicate with the outside, and then the cavity is filled with pouring material, so as to eliminate the cavity.

[0048] Preferably, the first hole body 104 is arranged as an open surface communicating with the outside on one side of the end of the plate body 100, and correspondingly, when two adjacent plate bodies 100 are connected, the first hole body 104 is used as an observation hole. Based on this, the observation area is further enlarged, so that the staff can more intuitively and accurately judge the alignment condition, the extension condition of the clamping rod 102, and the like, which is helpful to improve the efficiency of the connection work.

[0049] In a possible implementation, the inner wall surface of the clamping hole 103 is provided with a fixing layer matched with the clamping rod 102, or the end surface of the plate body 100 is detachably connected with a cover body for shielding. Based on the above design scheme, generally, during the transportation of the plate body 100, the clamping rod 102 is received in the clamping hole 103 to reduce the length of the plate body 100 as a whole. At this time, by arranging the fixing layer, the friction between the clamping rod 102 and the clamping hole 103 is increased to achieve fixation, so as to effectively avoid the probability of accidental sliding of the clamping rod 102 out of the clamping hole 103. Similarly, the cover body can also be used for limiting, and the cover body can be removed when the plate body 100 is connected.

[0050] In a possible implementation, the pulling member 200 includes a base plate 210, a pulling plate 220 and a pulling rope 230.

[0051] The bottom surface of the base plate 210 is detachably connected to the plate body 100, and the top surface of the base plate 210 is detachably connected to the pulling plate 220.

[0052] The pulling plate 220 is provided with a first fixed hole 240 recessed therein, and correspondingly, the pulling plate 220 is detachably connected to the pulling rope 230 through the first fixed hole 240.

[0053] The pulling rope 230 has opposite two ends, one end of which is detachably connected to the pulling plate 220, and the other end is detachably connected to the clamping rod 102.

[0054] Correspondingly, the plate body 100 is provided with an additional hole 106 adjacent to the hole bottom of the receiving hole 101 and communicating with the receiving hole 101, and the pulling rope 230 is arranged to pass through the receiving hole 101 and the additional hole 106, so that the two ends of the pulling rope 230 are connected to the clamping rod 102 and the pulling plate 220, respectively.

[0055] According to the above design scheme, the substrate 210 and the pull plate 220 are fixed on the plate body 100, the two ends of the pull rope 230 are connected to the pull plate 220 and the clamping rod 102 respectively, the additional hole 106 is arranged to guide the moving direction of the clamping rod 102, so that the clamping rod 102 moves towards the corresponding receiving hole 101.

[0056] For the plate body 100 provided with the preformed through hole, the pull rope 230 can be inserted from one end of the through hole, and the other end of the pull rope 230 is connected to the clamping rod 102. At this time, the two ends of the through hole of the plate body 100 are used as the receiving hole 101 and the clamping hole 103 respectively, and the clamping rod 102 in the clamping hole 103 should be removed when the pull rope 230 is inserted to avoid blocking. In other words, for the plate body 100 provided with the preformed through hole, the additional hole 106 can not be arranged thereon.

[0057] After the pull rope 230 is connected, the staff removes the pull plate 220 from the substrate 210, and then pulls the pull plate 220, so that the pulling force is transmitted to the clamping rod 102 through the pull plate 220 and the pull rope 230, thereby pulling the clamping rod 102 out of the receiving hole 101 and inserting the clamping rod 102 into the receiving hole 101. Figure 3 As shown in FIG. 6, after the clamping rod 102 is inserted into the receiving hole 101, the connection between the pull rope 230 and the clamping rod 102 can be released, so that the pulling piece 200 can be used for the next time.

[0058] It is easy to understand that in the above process, the pull rope 230 will be in contact with the inner wall surface of the receiving hole 101 and the additional hole 106 respectively, and the movement of the pull rope 230 will cause the surface of the pull rope 230 to wear. At this time, the pull rope 230 is preferably an existing model with good wear resistance to improve the service life.

[0059] It is easy to understand that the substrate 210 is connected to the plate body 100 and the pull plate 220 by any suitable detachable connection mode, and the present application does not make any limitation on this.

[0060] In one possible implementation, the pull rope 230 includes a pull rope body 231 and a connecting column 232, wherein the two ends of the pull rope body 231 are connected to one connecting column 232 respectively, and at least two clamping columns 233 are arranged on the outer peripheral surface of the connecting column 232. According to the above design scheme, the pull rope body 231 can be selected from any suitable existing model, and preferably an existing model with good wear resistance. The connecting column 232 is connected and limited by the clamping column 233 to ensure the connection quality and accurately transmit the pulling force.

[0061] In a possible implementation, the first fixing hole 240 comprises a base hole 241 adapted to the connecting column 232 and a sliding groove 242 provided with a clamping column 233, the base hole 241 is in communication with the sliding groove 242, and the sliding groove 242 is open at one end and extends into the base hole 241 and is connected with an arc-shaped slot 243 for limiting.

[0062] Based on the above design scheme, in combination with the structure of the connecting column 232, when the pull rope 230 is connected to the pull plate 220, the connecting column 232 is inserted into the base hole 241, and at the same time, the clamping column 233 is inserted into the sliding groove 242. The connecting column 232 and the clamping column 233 move towards the bottom of the base hole 241 at the same time, until the connecting column 232 abuts against the bottom of the hole, or the clamping column 233 moves to the arc-shaped slot 243, and the connecting column 232 is rotated to make the clamping column 233 slide into the arc-shaped slot 243, and the limiting is realized by the abutment of the clamping column 233 and the arc-shaped slot 243. Further, the reverse operation can detach the connecting column 232 from the pull plate 220.

[0063] Preferably, the end of the clamping rod 102 is provided with a second fixing hole which has the same structure as the first fixing hole 240. Based on this, the design cost is simplified, and the two ends of the pull rope 230 have universality. At the same time, the disassembly principle of the pull rope 230 and the clamping rod 102 is the same as that of the pull rope 230 and the pull plate 220, and the disassembly of the pull rope 230 and the clamping rod 102 will not be described here.

[0064] In a possible implementation, the pulling member 200 further comprises a pulley 300, the pulley 300 comprises a base 301 and a pulley body 302, the base 301 is detachably arranged on the plate body 100, and the pulley body 302 is rotatably arranged on the base 301. Correspondingly, the pull rope 230 is arranged around the pulley body 302.

[0065] Based on the above design scheme, the direction of the pull rope 230 is changed through the pulley 300, that is, as shown in Figure 2 The pulling member 200 and the clamped rod 102 being pulled can be located on the same plate body 100, thereby reducing the space required for the operation of the pulling member 200. At the same time, when the pull rope 230 passes around the pulley body 302, the contact area of the pull rope 230 with the receiving hole 101 and the additional hole 106 can be reduced to some extent, which helps to reduce the wear of the pull rope 230.

[0066] It is easy to understand that the base 301 can be constructed in any suitable structure, and the pulley body 302 can be selected from any suitable existing model.

[0067] In a possible implementation, the receiving hole 101 comprises an outer zone, an intermediate zone and a bottom zone in sequence, the outer zone is communicated with the outside and the first hole body 104, the inner wall surface of the intermediate zone is provided with a damping layer for fixing the clamping rod 102, and the bottom zone is communicated with the outside through the additional hole 106.

[0068] Based on the above design scheme, the outer zone cooperates with the first hole body 104, so as to facilitate the observation and adjustment of the position of the plate body 100 by the staff. The intermediate zone increases the friction with the clamping rod 102 through the damping layer, improves the reliability and quality of the connection, and the bottom zone is used for penetrating the pull rope 230, and after the clamping rod 102 is inserted into the receiving hole 101, the bottom zone also provides an operation space for the separation of the pull rope 230 and the clamping rod 102.

[0069] It is worth noting that, as shown in Figure 4 When two adjacent plate bodies 100 are connected, the bottom region of the clamping hole 103, the first hole body 104, the bottom zone of the receiving hole 101 and the additional hole 106 are all cavities, and a certain amount of filling material should be injected for filling, so as to avoid the use defects such as noise of the assembled composite floor slab due to the cavities.

[0070] The above specific embodiments further specifically explain the purpose, technical scheme and beneficial effects of the present application, and it should be understood that the above is only a specific embodiment of the present application, and is not used to limit the protection scope of the present application, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application should be included in the protection scope of the present application.
