Description

Technical Field

[0001] The invention relates to the field of assembly box construction, and in particular to a hollow floor structure and a construction method. Background Art

[0002] Prefabricated buildings are becoming increasingly common in the construction industry, and assembly boxes are a common component of these structures. However, during the concrete pouring process, these boxes are prone to floating and shifting, causing them to fail to meet design requirements, altering the structure's load-bearing capacity, leading to quality defects and increasing the workload for workers to correct them. This significantly reduces construction efficiency, and some boxes even risk becoming irreversibly repositioned, creating significant management difficulties and quality risks for daily production.

[0003] Therefore, in order to solve the above problems, a hollow floor structure and construction method are needed to improve the construction stability of the assembly box and thus improve the construction efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to overcome the defects in the prior art and provide a hollow floor structure and construction method, which can improve the construction stability of the assembly box and thus improve the construction efficiency.

[0005] The hollow floor structure of the present invention comprises adjacently arranged assembly boxes, ribbed steel cages arranged between the adjacent assembly boxes, and a supporting body connecting the adjacent assembly boxes and the ribbed steel cages;

[0006] It also includes an anti-floating component, which includes a supporting cross bar and a supporting vertical bar. The supporting cross bar has a first cross end and a second cross end that are laterally separated. The distance between the first cross end and the second cross end is adjustable so that the first cross end and the second cross end are correspondingly supported between adjacent assembly boxes when in use; the supporting vertical bar is vertically arranged to the supporting cross bar, and the supporting vertical bar has a first vertical end for supporting the rib beam steel cage.

[0007] Furthermore, there are two supporting vertical rods, and the two supporting vertical rods are respectively close to the first horizontal end and the second horizontal end, and the two supporting vertical rods are symmetrical about the horizontal center of the supporting horizontal rod.

[0008] Furthermore, the rib beam reinforcement cage has two rib beam top bars located at the top of the assembly box. The two rib beam top bars are respectively close to the first horizontal end and the second horizontal end, and are supported by the supporting vertical rods on the corresponding sides.

[0009] Furthermore, the height of the supporting vertical rod is adjustable.

[0010] Furthermore, in the cross section, the first vertical end of the supporting vertical rod is in an arc shape that supports the bottom end of the top rib of the rib beam.

[0011] Furthermore, the first and second transverse ends of the support crossbar are respectively supported on the top edges of adjacent assembly boxes, and in cross section, the first and second transverse ends are respectively in an "L" shape that conforms to the top edges of the corresponding assembly boxes.

[0012] Furthermore, the assembly box includes a bottom plate, a top plate, and a plurality of side plates located between the bottom plate and the top plate. The plurality of side plates, the top plate, and the bottom plate are assembled together to form a hollow box structure.

[0013] Furthermore, the periphery of the bottom plate has shear grooves.

[0014] Furthermore, the peripheral edge of the bottom plate protrudes upward to form a bottom protective edge, the peripheral edge of the top plate protrudes downward to form a top protective edge, and the side plates are supported between the bottom protective edge and the top protective edge.

[0015] This solution also discloses a construction method based on the hollow floor structure, which includes the following construction steps:

[0016] S1. Transport the bottom plate, top plate and side plates of the assembly box to the construction site;

[0017] S2. Set up the main formwork;

[0018] S3. Set the main beam reinforcement, the bottom plate of the assembly box, the ribbed beam reinforcement cage, the side panels of the assembly box and the top plate of the assembly box in sequence on the main template;

[0019] S4. Anti-floating components are provided between adjacent assembly boxes;

[0020] S5. Set the slab reinforcement and pour concrete.

[0021] The beneficial effects of the present invention are as follows: a hollow floor structure and construction method disclosed in the present invention supports two adjacent assembly boxes through the first horizontal end and the second horizontal end of the horizontal bar with adjustable spacing, thereby improving the bonding strength between the two assembly boxes, thereby reducing the floating and displacement of the assembly boxes. At the same time, this solution also limits the supporting horizontal bar connecting the two assembly boxes on the supporting rib beam again through the supporting vertical bar, further reducing the floating and displacement of the assembly boxes during the concrete pouring process, thereby meeting the preset design requirements and improving the construction quality and construction efficiency.

[0029] Figure 1 This is a structural diagram of the present invention. As shown in the figure, the hollow floor structure in this embodiment includes adjacent assembly boxes 1, ribbed steel cages 2 arranged between adjacent assembly boxes 1, and a supporting body connecting the adjacent assembly boxes 1 and the ribbed steel cages 2;

[0030] It also includes an anti-floating component 3, which includes a supporting cross bar 4 and a supporting vertical bar 5. The supporting cross bar 4 has a first horizontal end 6 and a second horizontal end 7 that are laterally separated. The distance between the first horizontal end 6 and the second horizontal end 7 is adjustable so that the first horizontal end 6 and the second horizontal end 7 are correspondingly supported between adjacent assembly boxes 1 when in use; the supporting vertical bar 5 is vertically arranged on the supporting cross bar 4, so that the overall structure is more stable, the composite force on the overall structure is reduced, and the structural reliability is improved. The supporting vertical bar 5 has a first vertical end 8 for supporting the rib beam reinforcement cage 2. The height of the supporting vertical bar 5 is adjustable so that the height of the first vertical end 8 is adjustable. The horizontal Figure 2 In the horizontal direction, the longitudinal direction is Figure 2 The structure for adjusting the horizontal and vertical spacing includes a telescopic rod with damping force, a structure for the slider to cooperate with the slide rail, and a structure for bolt thread assembly, etc., so as to achieve the adjustable length of the supporting cross bar 4 and the supporting vertical bar, thereby improving the adaptability and versatility of the structure. ...

[0031] When in use, the supporting cross bar 4 is roughly located in the middle of the adjacent assembly boxes 1 to further improve the support reliability and reduce the possibility of the assembly box 1 floating or shifting due to force. This solution supports the two adjacent assembly boxes 1 through the first cross end 6 and the second cross end 7 with adjustable spacing in the support cross bar, thereby improving the bonding strength between the two assembly boxes 1 and reducing the floating and displacement of the assembly boxes 1. At the same time, this solution also limits the supporting cross bar 4 connecting the two assembly boxes 1 to the supporting rib beam again through the supporting vertical rod 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 construction quality and efficiency.

[0032] In this embodiment, there are two support vertical rods 5, and the two support vertical rods 5 are respectively close to the first horizontal end 6 and the second horizontal end 7, and the two support vertical rods 5 are symmetrical with the horizontal center of the support crossbar 4; the rib beam reinforcement cage 2 has a rib beam top rib 9 located at the top of the assembly box 1, and the rib beam top rib 9 is two, and the two rib beam top ribs 9 are respectively close to the first horizontal end 6 and the second horizontal end 7, and are supported by the support vertical rod 5 on the corresponding side; specifically, the two rib beam top ribs 9 are respectively located at the two tops of the rib beam reinforcement cage 2 The rib beam reinforcement cage 2 also has a rib beam bottom reinforcement 10, and there are two rib beam bottom reinforcements 10. The two rib beam bottom reinforcements 10 are respectively located at the two bottom corners of the rib beam reinforcement cage 2, and the two rib beam top reinforcements 9 and the two rib beam bottom reinforcements 10 are tied together into a rectangular structure. The two rib beam bottom reinforcements 10 are connected to the bottom of the two adjacent assembly boxes 1 through the main beam reinforcement 11 supporting the main body, and the two rib beam top reinforcements 9 are connected to the top of the two adjacent assembly boxes 1 through the anti-floating component 3, which improves the structural integrity and consistency and ensures reliability in use. Since the rib beam reinforcement cage 2 and the two adjacent assembly boxes 1 are connected in series on the supporting body to form a whole, the bottoms of the three are flush. In this case, combined with the support cross bars 4 that support the adjacent assembly boxes 1 and the support vertical bars that connect the cross bars and the tops of the rib beam reinforcement cages 2, the adjacent assembly boxes 1, the rib beam reinforcement cages 2 and the anti-floating components 3 form a whole. Especially during construction, multiple groups of anti-floating components 3 are arranged, so that the assembly boxes 1 that form the hollow floor as a whole are 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.

[0033] In this embodiment, the first vertical end 8 of the support vertical rod 5 is in an arc shape in cross section to support the bottom end of the rib top rib 9, that is, when in use, the end of the support vertical rod 5 is in an arc shape to support the bottom end of the rib top rib 9. Figure 2 As shown in the cross-section, the first vertical end of the supporting vertical rod 5 is a semicircular arc surface supporting the bottom end of the rib beam top reinforcement 9. When in use, the supporting vertical rod 5 forms a support for the corresponding rib beam top reinforcement 9 to improve the structural stability. In particular, the supporting vertical rods 5 are two relatively far apart in the horizontal direction, which can ensure the balance of force applied to the rib beam reinforcement cage 2, so that the overall structural strength is higher, and the anti-floating ability and anti-disturbance ability are better.

[0034] In this embodiment, the first transverse end 6 and the second transverse end 7 of the support crossbar 4 are respectively supported on the top edge of the adjacent assembly box 1, that is, the transition position of the adjacent surfaces shown in the figure. In the cross section, the first transverse end 6 and the second transverse end 7 are respectively "L"-shaped and conform to the top edge of the corresponding assembly box 1. Compared with the support structure of the vertical plate type, the "L"-shaped first transverse end 6 and the second transverse end 7 also have the function of actively limiting the assembly box 1, which can further suppress the buoyancy 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-floating components 3 are used on a large scale, the assembly boxes 1 are connected to each other to form a whole, and the overall anti-floating and anti-vibration capabilities are better.

[0035] In this embodiment, the support crossbar 4 includes a crossbar sleeve 12 and a first crossbar 13 and a second crossbar 14 correspondingly provided at both ends of the crossbar sleeve 12, the first crossbar 6 being located on the first crossbar 13 and the second crossbar 7 being located on the second crossbar 14, and the first crossbar 13 and the second crossbar 14 being driven to slide within the crossbar sleeve 12; the support crossbar also includes a first locking member 15 for limiting the first crossbar 13 to the corresponding position within the crossbar sleeve 12, and the crossbar also includes a second locking member 16 for limiting the second crossbar 14 to the corresponding position within the crossbar sleeve 12. That is, in this embodiment, the first crossbar 13 and the second crossbar 14 are of a structure that can be plugged in and out of 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 is easy to adjust. In particular, it has a certain torsion resistance and high structural strength.

[0036] In this embodiment, the supporting vertical rod includes a longitudinal rod sleeve 17 and a first longitudinal rod 18 and a second longitudinal rod 19 correspondingly arranged at both ends of the longitudinal rod sleeve 17. The first vertical end is located at the first longitudinal rod 18, and the second longitudinal rod 19 is vertically arranged on the supporting cross bar 4. The first longitudinal rod 18 and the second longitudinal rod 19 are each driven to slide in the longitudinal rod sleeve 17; the longitudinal rod also includes a third locking member 20 and a fourth locking member 21 for limiting the first longitudinal rod 18 and the second longitudinal rod 19 to the longitudinal rod sleeve 17 respectively.

[0037] That is, in this solution, the first longitudinal rod 18 and the second longitudinal rod 19 are structures that are plugged in and out of 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 torsion resistance and high structural strength.

[0038] In this embodiment, the assembly box 1 includes a bottom plate 22, a top plate 23, and a plurality of side plates 24 located between the bottom plate 22 and the top plate 23. The plurality of 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 is a rectangular cube structure. The adjacent plates constituting the assembly box 1 are connected to form a whole by connecting glue. The connecting glue has a certain connection ability and a certain anti-penetration ability. It has better sealing performance and can prevent leakage during use. It is a multifunctional connection method. Of course, the adjacent plates constituting the assembly box 1 can also be connected to form a whole by other connection methods in the prior art, such as nail connection or bolt connection, which will not be repeated here. The split structure of the assembly box 1 of this solution is extremely convenient in handling, installation, and transportation, and compared with the integral assembly box 1, it can reduce the situation of component damage and scrapping, and has the advantage of low cost.

[0039] In this embodiment, through holes are reserved on the bottom plate 22 for the main beam reinforcement 11 to pass through, so that when in use, the bottom plate 22 is set on the supporting body through the main beam reinforcement 11, thereby improving construction convenience and efficiency.

[0040] In this embodiment, the periphery of the base plate 22 has shear grooves 25, and the shear grooves 25 are arranged around the periphery of the base plate 22 so that when the concrete is subsequently poured, the connection strength between the assembly box 1 and the supporting body is improved, and the assembly box 1 has a certain pull-out resistance and shear resistance, and the structural strength is more reliable, thereby ensuring the construction quality of the hollow floor.

[0041] In this embodiment, a functional hole 26 is passed through the bottom of the base plate 22. The functional hole 26 mainly serves the purpose of ventilation and pressure equalization, and is also used for drainage in special circumstances. The hole 26 is sealed after the entire concrete is poured.

[0042] In this embodiment, the periphery of the bottom plate 22 protrudes upward to form a bottom guard edge 27, and the periphery of the top plate 23 protrudes downward to form a top guard edge 28, and the side plate 24 is supported between the bottom guard edge 27 and the top guard edge 28; the structural stability is improved; the top surface of the bottom guard edge 27 is recessed downward to form a embedding groove, and the bottom of the side plate 24 is arranged in the embedding groove, so that the bottom surface of the side plate 24 is not higher than the top surface of the bottom guard edge 27; the embedding groove is located on the outside of the bottom guard edge 27, and the groove shape of the embedding groove is an "L" shape with the opening facing outward; so as to facilitate the side plate 24 to form protection for the bottom plate 22, especially protection against rainwater and slurry, etc., thereby improving construction quality.

[0043] In this embodiment, the side panels 24 have a fireproofing function. More specifically, any high-strength fireproofing board in the prior art is selected to ensure application capability and achieve the corresponding fireproofing purpose, so that the hollow floor has both fireproofing capability and durability.

[0044] This solution also discloses a construction method based on the hollow floor structure, which includes the following construction steps:

[0045] S1 will constitute the bottom plate 22, top plate 23 and side panels 24 of the assembly box 1 are transported to the construction site;

[0047] S3. The main beam reinforcement 11 is sequentially provided on the main template, the bottom plate 22 of the assembly box 1, the rib beam reinforcement cage 2, the side plates 24 of the assembly box 1 and the top plate 23 of the assembly box 1;

[0048] S4. Anti-floating assembly 3 is provided between adjacent assembly boxes 1;

[0049] S5. Set the slab reinforcement and pour concrete.

[0050] The split-structure assembly box 1 can greatly simplify the construction process and ensure the construction quality. In particular, the present solution also utilizes the anti-floating component 3 to limit the assembly box 1, thereby preventing floating and displacement and improving the construction quality of the hollow floor.
