Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite board technology, and in particular to a composite board with rapid splicing capability. Background Technology
[0002] Composite slabs are the core horizontal components of prefabricated buildings, which are formed by combining precast concrete base slabs with cast-in-place concrete layers to create an integral load-bearing floor slab system.
[0003] Existing composite slabs require splicing during use. The lack of a positioning mechanism on the composite slabs makes positioning difficult, resulting in slow splicing speed and poor performance. Furthermore, the bottom slab of the composite slab is only supported by an internal steel reinforcement frame, leading to low overall structural strength. The bottom slab is connected to the cast-in-place concrete layer via a top truss, which can cause delamination between the concrete layer and the bottom slab during use, further contributing to poor performance.
[0004] Therefore, we provide a composite board with rapid assembly capabilities. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a composite board with rapid assembly capabilities, which can be positioned between two substrates through the cooperation of positioning blocks and positioning grooves, making positioning convenient.
[0006] In view of this, the present invention provides a composite board with rapid splicing, including a base plate, a first strip connecting plate installed on one side of the top of the base plate, and a second strip connecting plate installed on the other side of the top of the base plate. A positioning groove is provided on one side of the top of the second strip connecting plate, and a positioning block is installed on one side of the top of the first strip connecting plate. One end of each positioning block extends to one side of the base plate, and when two base plates are spliced, one end of each positioning block extends into the corresponding positioning groove.
[0007] The top of the substrate is equipped with several sets of trusses, the bottom of which is embedded in the substrate. Several reinforcing ribs are provided between two adjacent sets of trusses, and both ends of the reinforcing ribs are connected to the trusses through a connecting mechanism.
[0008] Preferably, when one end of the positioning block extends into the corresponding positioning groove, there is a gap between two adjacent substrates.
[0009] Preferably, each of the first and second strip-shaped connecting plates has mounting holes on its side. When one end of the positioning block extends into the corresponding positioning groove, the two corresponding mounting holes are aligned. Each mounting hole is provided with a pull screw, and both ends of the pull screw pass through the two corresponding mounting holes. Each pull screw has a locking sleeve threaded onto both ends. The sides of the first and second strip-shaped connecting plates abut against the ends of the corresponding locking sleeves.
[0010] Preferably, the connecting mechanism includes a first arc-shaped connecting sleeve installed at both ends of the reinforcing rib, and a second arc-shaped connecting sleeve is provided on one side of each of the first arc-shaped connecting sleeves. The first arc-shaped connecting sleeves and the second arc-shaped connecting sleeves abut against each other at their proximal ends, and a receiving space is formed between them. One end of the truss passes through this space.
[0011] Preferably, each of the first arc-shaped connecting sleeve and the second arc-shaped connecting sleeve has a skirt at both ends, and the two skirts on the same side are connected by bolts.
[0012] Preferably, there is a gap between the bottom of the reinforcing rib and the top of the substrate.
[0013] Preferably, the top of the truss is higher than the top of the first strip connecting plate and the top of the second strip connecting plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0025] A type of composite panel with rapid assembly, such as Figures 1-4 As shown, the system includes a substrate 1, a first strip-shaped connecting plate 2 mounted on one side of the top of the substrate 1, and a second strip-shaped connecting plate 8 mounted on the other side of the top of the substrate 1. A positioning groove 10 is provided on one side of the top of the second strip-shaped connecting plate 8, and a positioning block 3 is mounted on one side of the top of the first strip-shaped connecting plate 2. One end of each positioning block 3 extends to one side of the substrate 1. When two substrates 1 are spliced, one end of each positioning block 3 extends into the corresponding positioning groove 10. In actual splicing, the two substrates 1 can be positioned by moving the positioning block 3 into the positioning groove 10. Positioning is convenient and splicing speed is fast.
[0026] It should be noted that when one end of the positioning block 3 extends into the corresponding positioning groove 10, there is a gap between two adjacent base plates 1. A certain distance is reserved between the two base plates 1 so that concrete can be poured into this gap during subsequent pouring, thereby improving the stability of the splicing between the two base plates 1.
[0027] like Figure 1 and Figure 4 As shown, each of the first strip connecting plate 2 and the second strip connecting plate 8 has mounting holes 9 on its side. When one end of the positioning block 3 extends into the corresponding positioning groove 10, the two corresponding mounting holes 9 are aligned. The mounting holes 9 are equipped with pull screws 4, and both ends of the pull screws 4 pass through the two corresponding mounting holes 9. Each pull screw 4 has a locking sleeve 5 threaded on both ends. The sides of the first strip connecting plate 2 and the second strip connecting plate 8 abut against the ends of the corresponding locking sleeves 5. After the splicing is completed, the workers can pass the pull screws 4 through the corresponding mounting holes 9 and tighten the locking sleeves 5 to fix the first strip connecting plate 2 and the second strip connecting plate 8 together. This will fix the two adjacent base plates 1 and prevent the two adjacent base plates 1 from shifting during subsequent pouring.
[0028] like Figure 1 and Figure 2 As shown, several sets of trusses 6 are installed on the top of the substrate 1. The bottom of each truss 6 is embedded inside the substrate 1. Several reinforcing ribs 7 are provided between two adjacent sets of trusses 6. Both ends of the reinforcing ribs 7 are connected to the trusses 6 through a connecting mechanism. In actual use, by setting reinforcing ribs 7 between two adjacent sets of trusses 6, the structural strength of the trusses 6 can be increased. At the same time, during casting, the connection area between the casting layer and the substrate 1 can be increased, the connection strength between the casting layer and the substrate 1 can be improved, and the performance can be improved.
[0029] The specific structure of the connecting mechanism is as follows: the connecting mechanism includes a first arc-shaped connecting sleeve 11 installed at both ends of the reinforcing rib 7. Each first arc-shaped connecting sleeve 11 has a second arc-shaped connecting sleeve 12 on one side. The first arc-shaped connecting sleeve 11 and the second arc-shaped connecting sleeve 12 abut each other at their near ends, and a receiving space is formed between them. One end of the truss 6 passes through this space. Each first arc-shaped connecting sleeve 11 and the second arc-shaped connecting sleeve 12 has a skirt 13 at both ends. The two skirts 13 on the same side are connected by bolts 14. The first arc-shaped connecting sleeve 11 and the second arc-shaped connecting sleeve 12 can wrap around one end of the truss 6, and the first arc-shaped connecting sleeve 11 and the second arc-shaped connecting sleeve 12 are fixed together by bolts 14, so that the reinforcing rib 7 and the truss 6 can be connected together, and the connection is stable.
[0030] It should be noted that there is a gap between the bottom of the reinforcing rib 7 and the top of the base plate 1. During pouring, the concrete will pass through the bottom of the reinforcing rib 7, which can increase the contact area between the pouring layer and the reinforcing rib 7 and improve the pouring stability.
[0031] It should be noted that the top of the truss 6 is higher than the top of the first strip connecting plate 2 and the second strip connecting plate 8. In this way, during casting, the casting layer will overflow the first strip connecting plate 2 and the second strip connecting plate 8, making the connection between the two base plates 1 more stable.
[0032] In use, the operator first places the first arc-shaped connecting sleeves 11 at both ends of the reinforcing rib 7 onto the corresponding truss 6, then abuts the end of the corresponding second arc-shaped connecting sleeve 12 against the end of the first arc-shaped connecting sleeve 11, and then tightens the bolts 14 to fix the first arc-shaped connecting sleeve 11 and the second arc-shaped connecting sleeve 12 together, thus fixing the reinforcing rib 7 to the truss 6. This increases the structural strength of the base plate 1. One base plate 1 is placed in a preset position, and then another base plate 1 is hoisted to one side of the previous base plate 1 using a hoisting mechanism, so that the positioning block 3 installed on one side of the first strip connecting plate 2 on the hoisted base plate 1 is aligned with the previous base plate 6. Align the positioning grooves 10 on the second strip connecting plate 8 on the base plate 1, and then move the positioning block 3 into the corresponding positioning groove 10 to complete the splicing. The splicing is convenient. After the splicing is completed, the worker will pass the tie rod 4 through the corresponding mounting hole 9, and then put the locking nut 5 on the corresponding tie rod 4 and tighten it to fix the first strip connecting plate 2 and the second strip connecting plate 8 together. This will fix the two adjacent base plates 1 together. Then, the concrete will be poured. The poured concrete layer will overflow the truss 6. Under the action of the truss 6 and the reinforcing rib 7, the connection area between the concrete layer and the base plate 1 can be increased, and the stability can be improved.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
