Description

Technical Field

[0001] This utility model relates to the field of assembly box construction, specifically to a split-type assembly box. Background Technology

[0002] Currently, prefabricated buildings are increasingly common in the construction industry, and prefabricated boxes are one such component used to reduce the weight of concrete and increase the span of concrete structures. However, in practice, the handling and installation of prefabricated boxes are cumbersome, inconvenient to transport, and easily damaged. Furthermore, they are difficult to hoist, move, and position during installation, resulting in slow construction speed, low installation efficiency, and high costs.

[0003] Therefore, to solve the above problems, a modular assembly box is needed that can reduce the negative impacts of handling, installation and transportation of the integral assembly box, and improve the construction efficiency of the assembly box. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the defects in the prior art and provide a split assembly box that can reduce the negative impact of handling, installation and transportation of the integral assembly box and improve the construction efficiency of the assembly box.

[0005] The modular assembly box of this utility model includes a bottom plate, a top plate, and several side plates located between the bottom plate and the top plate. The several side plates, the top plate, and the bottom plate are assembled together to form a hollow box structure.

[0006] The base plate has pre-drilled holes for the main beam reinforcement bars to pass through, so that when in use, the base plate is set on the supporting body through the main beam reinforcement bars.

[0007] Furthermore, the bottom periphery of the base plate has shear teeth.

[0008] Furthermore, the periphery of the bottom plate protrudes upward to form a bottom flange, the periphery of the top plate protrudes downward to form a top flange, and the side plate is supported between the bottom flange and the top flange.

[0009] Furthermore, the top surface of the bottom edge is recessed downward to form a groove, and the bottom of the side plate is disposed in the groove so that the bottom surface of the side plate is not higher than the top surface of the bottom edge.

[0010] Furthermore, the groove is located on the outside of the bottom edge, and the groove is an open "L" shape.

[0011] Furthermore, the side panel has fire-resistant properties.

[0012] Furthermore, the top plate is a precast concrete slab.

[0013] Furthermore, the bottom of the base plate has a through-hole.

[0014] Furthermore, adjacent panels that make up the assembly box are connected together with adhesive to form a whole.

[0015] The beneficial effects of this utility model are as follows: The modular assembly box disclosed in this utility model has a rectangular cubic structure. The adjacent plates constituting the assembly box are connected to form a whole by a connecting adhesive. The connecting adhesive has a certain bonding ability and a certain anti-permeability ability, resulting in better sealing and preventing grout leakage during use. It is a multi-functional connection method. The modular structure of this assembly box is extremely convenient in handling, installation, and transportation, resulting in higher construction efficiency. Compared with the integral assembly box, it can reduce the occurrence of component damage and scrap, and has the advantage of low cost. Attached Figure Description

[0023] Figure 1 This is a schematic diagram of the structure of the present invention. As shown in the figure, the split assembly box 1 in this embodiment is further explained by taking its application in a hollow floor slab structure as an example. The hollow floor slab structure includes adjacent assembly boxes 1, a rib beam steel cage 2 set between adjacent assembly boxes 1, and a supporting body that connects the adjacent assembly boxes 1 and the rib beam steel cage 2.

[0024] It also includes an anti-buoyancy component 3, which comprises a supporting horizontal bar 4 and a supporting vertical bar 5. The supporting horizontal bar 4 has a first horizontal end 6 and a second horizontal end 7 that are laterally separated, and the distance between the first horizontal end 6 and the second horizontal end 7 is adjustable so that, in use, the first horizontal end 6 and the second horizontal end 7 are correspondingly supported between adjacent assembly boxes 1. The supporting vertical bar 5 is vertically arranged on the supporting horizontal bar 4, making the overall structure more stable, reducing the force exerted on the overall structure by the composite force, and improving the structural reliability. The supporting vertical bar 5 also has a first vertical end 8 for supporting the rib beam steel cage 2, and the height of the supporting vertical bar 5 is adjustable so that the height of the first vertical end 8 is also adjustable. The lateral direction is... Figure 2 In the horizontal direction, the longitudinal direction is Figure 2 The vertical direction is not described in detail here. The structures for adjusting the horizontal and vertical spacing include telescopic rods with damping force, sliding blocks with slide rails, and bolt thread assembly structures, etc., to make the usable length of the supporting horizontal bar 4 and the supporting vertical bar adjustable, thereby improving the structural adaptability and versatility. These will not be described in detail here.

[0025] During use, the support crossbar 4 is approximately located in the middle of the adjacent assembly box 1 to further improve the reliability of the support and reduce the possibility of the assembly box 1 floating or deviating under stress. This solution supports the two adjacent assembly boxes 1 through the first horizontal end 6 and the second horizontal end 7 with adjustable spacing between the crossbars, thereby improving the connection strength between the two assembly boxes 1 and reducing the floating and displacement of the assembly box 1. At the same time, this solution also limits the support crossbar 4 connecting the two assembly boxes 1 to the support rib beam again through the support vertical bar 5, further reducing the floating and displacement of the assembly box 1 during the concrete pouring process, thereby meeting the preset design requirements and improving the construction quality and efficiency.

[0026] In this embodiment, there are two supporting vertical rods 5, each approaching the first horizontal end 6 and the second horizontal end 7 respectively, and the two supporting vertical rods 5 are symmetrical about the transverse center of the supporting horizontal rod 4; the rib beam reinforcement cage 2 has two rib beam top bars 9 located at the top of the assembly box 1, each approaching the first horizontal end 6 and the second horizontal end 7 respectively, and is supported by the supporting vertical rods 5 on the corresponding sides; specifically, the two rib beam top bars 9 are respectively located at the two tops of the rib beam reinforcement cage 2. The rib cage 2 also has two bottom rib bars 10, which are located at the two bottom corners of the rib cage 2. The two bottom rib bars 10 are tied together to form a rectangular structure. The two bottom rib bars 10 are connected to the bottom of the two adjacent assembly boxes 1 through the main beam reinforcement 11 supporting the main body. The two top rib bars 9 are connected to the top of the two adjacent assembly boxes 1 through the anti-buoyancy component 3, which improves the overall integrity and consistency of the structure and ensures the reliability of use. Since the ribbed steel cage 2 and the two adjacent assembly boxes 1 are connected in series to form a whole on the supporting body, and the bottoms of the three are flush, in this case, combined with the support crossbar 4 that supports the adjacent assembly boxes 1 and the support vertical bar that connects the crossbar and the top of the ribbed steel cage 2, the adjacent assembly boxes 1, the ribbed steel cage 2 and the anti-buoyancy component 3 form a whole. Especially during construction, multiple sets of anti-buoyancy components 3 are set, so that the assembly boxes 1 that form a hollow floor slab are all connected to each other to form a whole, which has better stability and can overcome the floating and displacement of the assembly boxes 1 during the concrete pouring process, thereby ensuring the construction quality and improving the construction efficiency.

[0027] In this embodiment, the first vertical end 8 of the supporting vertical rod 5 is arc-shaped in the cross-section, supporting the bottom end of the top rib 9 of the rib beam. That is, in use, the end of the supporting vertical rod 5 is arc-shaped to support the bottom end of the top rib 9 of the rib beam. The cross-section is... Figure 2 As shown in the figure, the first vertical end of the support rod 5 is a semi-circular arc surface that supports the bottom end of the top reinforcement 9 of the rib beam. When in use, the support rod 5 forms a support for the corresponding top reinforcement 9 of the rib beam to improve the structural stability. In particular, the support rods 5 are two that are relatively far apart in the lateral direction, which can ensure the balance of force applied to the rib beam steel cage 2, so that the overall structural strength is higher and the anti-buoyancy and anti-disturbance capabilities are better.

[0028] In this embodiment, the first horizontal end 6 and the second horizontal end 7 of the supporting crossbar 4 are respectively supported on the top edge of the adjacent assembly box 1, that is, at the transition position of the adjacent surfaces shown in the figure. On the cross section, the first horizontal end 6 and the second horizontal end 7 are respectively in an "L" shape conforming to the top edge of the corresponding assembly box 1. Compared with the support structure of the vertical plate type, the "L" shaped first horizontal end 6 and the second horizontal end 7 also have the function of actively limiting the assembly box 1, which can further suppress the floating and vibration of the assembly box 1. In particular, the design of this structure transfers the buoyancy and vibration of the assembly box 1 to the rib beam steel cage 2. Especially when the anti-buoyancy component 3 is used extensively, the assembly boxes 1 are connected to form a whole, and the overall anti-buoyancy and anti-vibration capabilities are better.

[0029] In this embodiment, the supporting crossbar 4 includes a crossbar sleeve 12 and a first crossbar 13 and a second crossbar 14 correspondingly passing through both ends of the crossbar sleeve 12. The first crossbar end 6 is located at the first crossbar 13, and the second crossbar end 7 is located at the second crossbar 14. The first crossbar 13 and the second crossbar 14 are each driven to slide within the crossbar sleeve 12. The supporting crossbar also includes a first locking member 15 for correspondingly limiting the first crossbar 13 within the crossbar sleeve 12, and a second locking member 16 for correspondingly limiting the second crossbar 14 within the crossbar sleeve 12. That is, in this solution, the first crossbar 13 and the second crossbar 14 are inserted and removed within the crossbar sleeve 12. The first locking member 15 includes two bolts for fastening the first crossbar 13, and the second locking member 16 includes two bolts for fastening the second crossbar 14. The structure is simple and reliable, and easy to adjust. In particular, it has a certain torsional resistance and high structural strength.

[0030] In this embodiment, the supporting vertical rod includes a vertical rod sleeve 17 and a first vertical rod 18 and a second vertical rod 19 correspondingly inserted at both ends of the vertical rod sleeve 17. The first vertical end is located at the first vertical rod 18, and the second vertical rod 19 is vertically arranged on the supporting horizontal rod 4. The first vertical rod 18 and the second vertical rod 19 are each driven to slide within the vertical rod sleeve 17. The vertical rod also includes a third locking member 20 and a fourth locking member 21 for limiting the first vertical rod 18 and the second vertical rod 19 to be respectively located in the vertical rod sleeve 17.

[0031] That is, in this scheme, the first longitudinal rod 18 and the second longitudinal rod 19 are inserted and pulled in the longitudinal rod sleeve 17. The third locking member 20 includes a bolt for fastening the first longitudinal rod 18, and the fourth locking member 21 includes a bolt for fastening the second longitudinal rod 19. The structure is simple and reliable, and easy to adjust. In particular, it has a certain torsional resistance and high structural strength.

[0032] In this embodiment, the split-type assembly box 1 includes a bottom plate 22, a top plate 23, and several side plates 24 located between the bottom plate 22 and the top plate 23. The side plates 24, the top plate 23, and the bottom plate 22 are assembled together to form a hollow box structure. The assembly box 1 of this solution has a rectangular cubic structure. The adjacent plates constituting the assembly box 1 are connected to form a whole using adhesive. The adhesive has a certain bonding ability and a certain anti-permeability ability, resulting in better sealing and preventing grout leakage during use. It is a multi-functional connection method. Of course, the adjacent plates constituting the assembly box 1 can also be connected to form a whole using other connection methods in the prior art, such as nail connection or bolt connection, which will not be elaborated here. The split structure of the assembly box 1 of this solution is extremely convenient in handling, installation, and transportation. Compared with the integral assembly box 1, it can reduce the occurrence of component damage and scrap, and has the advantage of low cost.

[0033] In this embodiment, the base plate 22 has pre-drilled holes for the main beam reinforcing bars 11 to pass through, so that when in use, the base plate 22 is set on the supporting body through the main beam reinforcing bars 11; thus improving the convenience and efficiency of construction.

[0034] In this embodiment, the periphery of the base plate 22 has shear grooves 25, which are arranged around the periphery of the base plate 22 to improve the connection strength between the assembly box 1 and the supporting body during subsequent concrete pouring, and to provide a certain pull-out resistance and shear resistance, making the structural strength more reliable and ensuring the construction quality of the hollow floor slab.

[0035] In this embodiment, the bottom of the base plate 22 has a through-hole 26. The through-hole 26 mainly serves the purpose of ventilation and pressure equalization. In special cases, it is also used for drainage. It is sealed after the overall concrete pouring is completed.

[0036] In this embodiment, the periphery of the base plate 22 protrudes upward to form a bottom flange 27, and the periphery of the top plate 23 protrudes downward to form a top flange 28. The side plate 24 is supported between the bottom flange 27 and the top flange 28, thus improving structural stability. The top surface of the bottom flange 27 is recessed downward to form a groove, and the bottom of the side plate 24 is set in the groove so that the bottom surface of the side plate 24 is not higher than the top surface of the bottom flange 27. The groove is located on the outside of the bottom flange 27, and the groove is an open "L" shape. This facilitates the side plate 24 to protect the base plate 22, especially from rainwater and slurry, thereby improving construction quality.

[0037] In this embodiment, the side panel 24 has a fireproof function. More specifically, any high-strength fireproof board in the prior art is selected to ensure application capability and achieve the corresponding fireproof purpose, so that the hollow floor slab has both fireproof capability and durability.

[0038] This solution also discloses a construction method based on the hollow floor slab structure, including the following construction steps:

[0039] S1. Transport the bottom plate 22, top plate 23 and side plate 24 that make up the assembly box 1 to the construction site;

[0040] S2. Erect the main formwork;

[0041] S3. On the main formwork, the main beam reinforcement 11, the bottom plate 22 of the assembly box 1, the rib beam reinforcement cage 2, the side plate 24 of the assembly box 1 and the top plate 23 of the assembly box 1 are set in sequence.

[0042] S4. Install anti-buoyancy components 3 between adjacent assembly boxes 1;

[0043] S5. After setting the slab reinforcement, pour the concrete.

[0044] The modular assembly box 1 greatly simplifies the construction process and ensures construction quality. In particular, this solution also utilizes anti-buoyancy components 3 to limit the position of the assembly box 1, preventing floating and displacement, and improving the construction quality of the hollow floor slab.
