Description

Technical Field

[0001] The utility model relates to the technical field of building assembly, in particular to an assembled composite plate. Background Art

[0002] Concrete composite slab is an assembled integral floor slab composed of precast slabs and cast-in-place reinforced concrete layers. Concrete composite slab is not only one of the components of the floor structure, but also a permanent formwork for the cast-in-place reinforced concrete composite layer. Horizontal equipment pipelines can be laid in the cast-in-place composite layer. Concrete composite slab has good integrity and high rigidity, which can save formwork. In addition, the upper and lower surfaces of the slab are flat, which is convenient for the decoration of the finishing layer. It is suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity.

[0003] At present, the prefabricated panels and trusses of the current prefabricated composite slabs are usually set as an integrated structure during production. The composite panels are stacked together during transportation, which makes it easy for the trusses to bend and deform, causing the trusses to collapse toward the prefabricated panels. Ultimately, the firmness of the connection between the bent and deformed trusses and the cast-in-place concrete layer will deteriorate, thereby deteriorating the integrity of the floor slab. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide an assembled composite plate, which can prevent the truss from being bent and deformed by the prefabricated plate body during transportation.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A prefabricated composite panel comprises a prefabricated panel body, a truss and a plurality of fixing screws, wherein a limiting groove is provided on the prefabricated panel body; the truss comprises a compression rod and a plurality of support frames, wherein the plurality of support frames are arranged along the length direction of the compression rod and the top of the support frame is detachably connected to the compression rod, and the bottom of the support frame is fixedly connected to a fixing block, which can slide into or out of the limiting groove and has its upper and lower freedom restricted by the limiting groove; the plurality of fixing screws are distributed on both sides of the limiting groove and correspond to the fixing blocks respectively, and the fixing screws penetrate the top wall of the limiting groove and can be threadedly connected to the fixing block.

[0007] As an optional solution, the support frame includes a semicircular clamp and four supporting feet. The semicircular clamp is detachably connected to the pressure rod by bolts, and the lower ends of the four supporting feet are respectively fixedly connected to the four corners of the fixed block, and the upper ends of the four supporting feet are fixedly connected to the bottom of the semicircular clamp.

[0008] As an optional solution, the semicircular clamp and the pressure rod are provided with through holes which penetrate both of them from top to bottom, and the semicircular clamp is further fixed to the pressure rod by bolts arranged in the through holes.

[0009] As an optional solution, the limiting groove is in an inverted "T" shape, and the limiting groove passes through both ends of the prefabricated board body along the length direction of the prefabricated board body.

[0010] As an optional solution, the fixing block is square in shape, and is slidably connected in a transverse groove of the inverted “T”-shaped limiting groove, and the support frame passes through a vertical groove of the limiting groove to connect to the fixing block.

[0011] As an optional solution, the fixing screw is a hexagon socket screw, the top wall of the limiting groove is provided with a countersunk hole, and the fixing screw is installed in the countersunk hole.

[0012] As an optional solution, it also includes reinforcing steel bars that are arranged through the prefabricated panel body, and two ends of the reinforcing steel bars extend out from both sides of the top surface of the prefabricated panel body respectively.

[0013] Due to the adoption of the above technical solution, the utility model will have the following beneficial effects:

[0014] The utility model provides an assembled composite panel, which can limit the movement of the fixed block and fix the truss on the prefabricated panel by sliding the fixed block into the limit slot, tightening the corresponding fixing screw to limit the horizontal freedom of the fixed block, and cooperating with the limit slot that can limit the upper and lower freedom of the fixed block; when disassembling the truss, the fixing screw is loosened to slide the fixed block out of the limit slot to remove the truss from the prefabricated panel. The above-mentioned detachable truss can be used to transport the truss separately from the prefabricated panel to avoid the truss being bent and deformed by the prefabricated panel during transportation. At the same time, since the support frame is detachably connected to the pressure rod, the truss can be disassembled, and the pressure rod and the support frame connected to the fixed block can be transported separately, so that the prefabricated panel, the pressure rod and the support frame connected to the fixed block can be stacked together separately, saving space and facilitating transportation.

[0026] Please refer to Figure 1-6In one embodiment of an assembled composite panel of the utility model, the assembled composite panel includes a prefabricated panel body 1, a truss 2 and a plurality of fixing screws 31. The prefabricated panel body 1 is used to support the cast-in-place concrete layer above, and the two sides of the top surface of the prefabricated panel body 1 are respectively provided with limit grooves 11. The truss 2 is provided with two limit grooves 11 which are detachably mounted on the two sides of the top surface of the prefabricated panel body 1. When the concrete layer is poured above the prefabricated panel body 1, the concrete will contact the truss 2, and the truss 2 can play a reinforcing role on the cast-in-place concrete layer. Specifically, the truss 2 includes a compression rod 21, a plurality of support frames 22 and a plurality of fixed blocks 23 respectively corresponding to the support frames 22; wherein the compression rod 21 is arranged directly above the limiting groove 11 along the length direction of the limiting groove 11, a plurality of support frames 22 are arranged along the length direction of the compression rod 21 and the top of the support frame 22 is detachably connected to the compression rod 21, and a fixed block 23 is fixedly connected to the bottom of the support frame 22, the fixed block 23 can slide into or out of the limiting groove 11 and the upper and lower degrees of freedom are restricted by the limiting groove 11; a plurality of fixing screws 31 are distributed on both sides of the notch of the limiting groove 11 and correspond to each fixing block 23 respectively, the fixing screws 31 pass through the top wall of the limiting groove 11 and can be threadedly connected to the fixing block 23 to limit the horizontal degree of freedom of the fixing block 23. It should be noted that it is best to leave a certain gap between the fixing block 23 and the inner wall of the limiting groove 11 and between each fixing block 23, so that when pouring concrete on the prefabricated panel 1, the concrete can enter these gaps, thereby increasing the contact area between the truss 2 and the cast-in-place concrete layer, and further improving the firmness of the connection between the two.

[0027] When installing the truss 2, slide the fixing block 23 into the limiting groove 11, tighten the corresponding fixing screw 31 to limit the horizontal freedom of the fixing block 23, and cooperate with the limiting groove 11 that can limit the upper and lower freedom of the fixing block 23 to limit the movement of the fixing block 23 so as to fix the truss 2 on the prefabricated panel 1. When disassembling the truss 2, loosen the fixing screw 31 to slide the fixing block 23 out of the limiting groove 11 to remove the truss 2 from the prefabricated panel 1. The above-mentioned detachable truss 2 can transport the truss 2 separately from the prefabricated panel 1, so as to facilitate stacking multiple composite panels together, reduce the space occupied by the composite panels, facilitate transportation, and prevent the truss 2 from being bent and deformed by the prefabricated panel 1 during transportation. At the same time, since the support frame 22 is detachably connected to the pressure rod 21, the truss 2 can also be disassembled, so as to transport the support frame 22 and the pressure rod 21 separately, which saves more space and is convenient for transportation.

[0028] Specifically, the support frame 22 includes a semicircular clamp 221 and four supporting feet 222. The semicircular clamp 221 is detachably sleeved on the compression rod 21 by bolts 5. In this way, the semicircular clamp 221 is sleeved on the compression rod 21 and the bolts 5 at both ends of the semicircular clamp 221 are tightened to fix the semicircular clamp 221 on the compression rod 21. Conversely, the bolts 5 at both ends of the semicircular clamp 221 are loosened to remove the semicircular clamp 221 from the compression rod 21. The lower ends of the four supporting feet 222 are respectively fixedly connected to the four corners of the fixing block 23, and the upper ends of the four supporting feet 222 are fixedly connected to the bottom of the semicircular clamp 221. In this way, the four supporting feet 222 and the fixing block 23 form a stable conical structure, thereby improving the stability of the truss 2.

[0029] Furthermore, in order to improve the fixing effect of the semicircular clamp 221, a through hole can be opened on the semicircular clamp 221 and the pressure rod 21 to penetrate the two from top to bottom. A bolt 5 is penetrated in the through hole, and the semicircular clamp 221 can further fix the pressure rod 21 through the bolt 5.

[0030] Specifically, the limiting groove 11 can be set in an inverted "T" shape, and the limiting groove 11 passes through both ends of the prefabricated board body 1 along the length direction of the prefabricated board body 1, so as to facilitate the sliding in and out of the fixing block 23.

[0031] More specifically, in order to improve the limiting effect of the limit groove 11 on the fixed block 23, the fixed block 23 can be set in a square shape, and the fixed block 23 is slidably connected in the horizontal groove of the inverted "T"-shaped limit groove 11; correspondingly, the support frame 22 passes through the vertical groove of the limit groove 11 to connect the fixed block 23.

[0032] Specifically, the fixing screw 31 can be set as a hexagon socket screw, which is easier to apply force and less likely to slide during use. A countersunk hole 32 is opened on the top wall of the limiting groove 11, and the fixing screw 31 is installed in the countersunk hole 32 to improve the load-bearing capacity.

[0033] On this basis, the assembled composite board of this embodiment also includes reinforcing steel bars 4 that are arranged throughout the prefabricated board body 1, and the two ends of the reinforcing steel bars 4 extend from both sides of the top surface of the prefabricated board body 1. By making the two ends of the reinforcing steel bars 4 extend from the top surface of the prefabricated board body 1 instead of extending from the end surface of the prefabricated board body 1, when the composite board is produced in advance, it is not necessary to open a hole on the mold used to produce the composite board, thereby improving the versatility of the mold and facilitating the standardization of the composite board production; on the other hand, since the steel bars are located above the composite board, when the composite board is installed, it is also convenient to displace and avoid the stirrups on the support beam used to support the composite board, making the installation operation easier.

[0034] The usage method or working principle of the utility model is as follows:

[0035] Before transporting the assembled composite panel, the fixing screws 31 can be loosened to slide the fixing block 23 out of the limiting groove 11 to remove the truss 2 from the prefabricated panel body 1, and then the truss 2 can be further disassembled, that is, the bolts 5 at both ends and the middle of the semicircular clamp 221 are loosened to remove the semicircular clamp 221 from the pressure rod 21, thereby disassembling the truss 2 into the pressure rod 21 and the support frame 22 connected to the fixing block 23; after completing the disassembly and disassembly of the truss 2, the prefabricated panel body 1, the pressure rod 21 and the support frame 22 connected to the fixing block 23 are transported separately, and then reinstalled to form the assembled composite panel after arriving at the site.

[0036] Since the prefabricated panel 1 and the truss 2 can be transported separately, the prefabricated panel 1 can be stacked together separately to prevent the truss 2 from being bent and deformed by the prefabricated panel 1 during transportation. At the same time, since the truss 2 itself is also detachable, the pressure rod 21 and the support frame 22 connected to the fixing block 23 can be transported separately, so that the prefabricated panel 1, the pressure rod 21 and the support frame 22 connected to the fixing block 23 can be stacked together separately, saving space and facilitating transportation.

[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
