It provides safety protection during the construction of steel decking and floor slab structures, reducing safety hazards.

Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a steel beam-attached integral hoisting enclosure and its construction method. Background Technology

[0002] Currently, the core tube + steel frame structure system is increasingly used in high-rise office buildings. Its construction process involves first constructing the core tube, then installing steel columns and beams, and finally laying steel decking and constructing the floor slab structure. The enclosure installation for the core tube + steel frame structure system is done temporarily after the floor slab is poured. This results in the lack of enclosure construction during the installation of steel columns, beams, and decking, as well as the reinforcement binding and concrete pouring of the floor slab, creating areas with relatively high safety hazards. Considering that the installation of steel columns and beams involves high-altitude assembly and lacks the conditions for enclosure installation, it is crucial to install enclosures in the steel decking and floor slab construction areas to reduce safety hazards. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a steel beam-attached integral hoisting enclosure and its construction method, effectively solving the safety hazards associated with installing temporary enclosure structures only after the floor slab has been poured in traditional construction.

[0004] The present invention achieves the above-mentioned technical objectives through the following technical means.

[0005] A steel beam-attached integral hoisting enclosure includes a steel beam body and an enclosure support beam. Multiple steel beam stiffening plates are welded evenly between the upper and lower flanges and the web of the steel beam body. One end of the enclosure support beam is connected to the steel beam stiffening plate, and the other end extends out of the steel beam body and is equipped with outer and inner columns. Enclosure panels are installed between adjacent outer columns, walkway panels are installed between adjacent enclosure support beams, and flaps are installed between adjacent inner columns on one side of the walkway panels.

[0006] Furthermore, the stiffening gusset plates of the steel beams are spaced 500mm apart, and the support beams of the enclosure frame are spaced 1500mm apart.

[0007] Furthermore, the outer and inner columns have the same structure but different heights; both the outer and inner columns have two column slots symmetrically arranged along the height direction on both sides of the column body, and each column body has a connection hole. Each column body has a base plate welded to the bottom, and each base plate has two base connecting ear plates welded to the lower surface of the base plate, and each base connecting ear plate has a connection hole.

[0008] Furthermore, the enclosure support beam is a steel box girder structure welded from steel plates. One end of the enclosure support beam is connected to the stiffening plate of the steel beam by high-strength connecting bolts. The two base connecting lugs of the outer column and the inner column are both snapped onto both sides of the enclosure support beam and fixed by high-strength connecting bolts.

[0009] Furthermore, the walkway slab includes a main frame composed of longitudinal keels, cross keels, and transverse keels welded together. Connecting ears are welded at the four corners of the main frame, and connecting ears are provided with connecting ear bolt holes. The walkway slab panel is welded to the upper surface of the main frame. The walkway slab is connected to the columns of the outer and inner columns through the connecting ears and high-strength connecting bolts.

[0010] Furthermore, the enclosure panel is welded together from two enclosure panels with the same structural dimensions. Each enclosure panel includes a main frame consisting of enclosure panel slot posts, enclosure panel top and bottom keels, and enclosure panel middle keel welded together. The enclosure panel protective mesh is welded and installed in the main frame. The size of the enclosure panel slot posts matches the column slots on both sides of the outer column body. The enclosure panel is embedded and installed between adjacent outer columns through the enclosure panel slot posts.

[0011] Furthermore, the flap includes a flap keel beam, with flap slot columns welded to both ends of the flap keel beam. The size of the flap slot columns matches the column slots on both sides of the inner columns. The flap is embedded and installed between adjacent inner columns through the flap slot columns. Multiple flap panels are installed on one side of the flap keel beam through flap hinges.

[0012] Furthermore, a lifting rod is welded at the middle position of the flap keel beam.

[0013] An installation method for the above-mentioned steel beam-attached integral hoisted enclosure includes the following steps:

[0014] Stiffening plates are welded onto the steel beam body, and the retaining frame support beam is connected to the stiffening plates using high-strength bolts. The base connecting lugs of the outer columns and the base connecting lugs of the inner columns are snapped onto the retaining frame support beam and connected using high-strength bolts. Then, the assembled steel beam body, stiffening plates, retaining frame support beam, outer columns, and inner columns are hoisted and placed onto the main building structure frame. Next, walkway panels are installed between adjacent retaining frame support beams, flap panels are installed between adjacent inner columns, and the flap panels are overlapped with the edge of the main building structure. Retaining panels are installed between the outer columns, and then steel decking is laid between the steel beam bodies, and the concrete floor structure is constructed.

[0015] The present invention has the following beneficial effects:

[0016] The enclosure frame of this invention is installed by bolting the support beams of the enclosure frame to the stiffening plates of the steel beams, the outer columns, and the inner columns, and then hoisting them together with the main structural steel beams onto the main building structure. Before laying the steel decking, only the walkway panels, enclosure panels, and flaps need to be bolted to the perimeter of the floor to quickly complete the installation of the enclosure frame. The enclosure panels and flaps all use a slot-type fixing structure, making disassembly and installation quick and convenient. The enclosure frame designed in this invention reduces the risks during the enclosure frame installation process, minimizes material waste, reduces labor costs, has a high turnover rate, is safe and reliable, easy to assemble and disassemble, and aesthetically pleasing. It provides safety protection during the construction of steel decking and floor slab structures, reducing safety hazards. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0030] like Figure 1 As shown, the steel beam attached integral hoisting enclosure frame of the present invention includes a steel beam body 1, a steel beam stiffening plate 2, an enclosure frame support beam 3, high-strength connecting bolts 4, an outer column 5, an inner column 6, a walkway 7, an enclosure plate 8, and a flip plate 9.

[0031] like Figure 1 As shown, the main body 1 of the steel beam is an I-beam structure. Multiple steel beam stiffening plates 2 are welded evenly between the upper and lower flanges and the web of the main body 1, with a spacing of 500mm between the stiffening plates 2. The stiffening plates 2 come in two forms: one with pre-drilled holes before processing, and the other without pre-drilled holes. After the holes are drilled, steel plates of the same diameter, material, and thickness are welded for reinforcement. A pre-drilled stiffening plate 2 is placed every two un-drilled plates (i.e., every 1500mm) for subsequent connection to the retaining frame support beam 3.

[0032] like Figure 3 , 4 As shown, the outer column 5 and the inner column 6 have the same structure, the only difference being their height.

[0033] like Figure 3As shown, the outer column 5 includes an outer column slot 5-1, an outer column body 5-2, an outer column walkway bolt connection hole 5-3, an outer column base connecting ear plate 5-4, an outer column base plate 5-5, and an outer column support beam connection hole 5-6. Two outer column slots 5-1 are symmetrically arranged along the height direction on both sides of the outer column body 5-2. An outer column walkway bolt connection hole 5-3 is opened at the lower part of the outer column body 5-2. An outer column base plate 5-5 is welded to the bottom of the outer column body 5-2. Two outer column base connecting ear plates 5-4 are welded to the lower surface of the outer column base plate 5-5. Each outer column base connecting ear plate 5-4 has an outer column support beam connection hole 5-6 for connecting with the enclosure frame support beam 3.

[0034] like Figure 4 As shown, the inner column 6 includes an inner column slot 6-1, an inner column walkway bolt connection hole 6-2, an inner column body 6-3, an inner column base connecting ear plate 6-4, an inner column base plate 6-5, and an inner column support beam connection hole 6-6. Two inner column slots 6-1 are symmetrically arranged along the height direction on both sides of the inner column body 6-3. The inner column body 6-3 has inner column walkway bolt connection holes 6-2. An inner column base plate 6-5 is welded to the bottom of the inner column body 6-3. Two inner column base connecting ear plates 6-4 are welded to the lower surface of the inner column base plate 6-5. Each inner column base connecting ear plate 6-4 has an inner column support beam connection hole 6-6 for connecting with the enclosure frame support beam 3.

[0035] like Figure 2 As shown, the retaining frame support beam 3 is made of 16mm thick Q355 steel plate welded into the form of a steel box beam. During processing, the retaining frame support beam 3 is provided with multiple connection holes for subsequent connection with the steel beam stiffening plate 2, outer column 5, and inner column 6. After the holes are opened, steel plates of the same diameter and material thickness are welded for reinforcement.

[0036] like Figure 2 , 5 As shown, one end of each retaining frame support beam 3 is connected to the corresponding steel beam stiffening plate 2 by three high-strength connecting bolts 4, and the other end extends out of the steel beam body 1. The part of each retaining frame support beam 3 extending out of the steel beam body 1 is connected to the outer column 5 and the inner column 6 by two high-strength connecting bolts 4; among them, the two inner column base connecting ear plates 6-4 of the inner column 6 are respectively snapped into both sides of the retaining frame support beam 3 and fixed by high-strength connecting bolts 4, and the two outer column base connecting ear plates 5-4 of the outer column 5 are respectively snapped into both sides of the retaining frame support beam 3 and fixed by high-strength connecting bolts 4.

[0037] like Figure 6 , 7As shown, the walkway slab 7 includes connecting ears 7-1, longitudinal keels 7-3, cross keels 7-4, transverse keels 7-5, and a panel 7-6. The longitudinal keels 7-3, cross keels 7-4, and transverse keels 7-5 are welded together to form the main frame of the walkway slab 7. Connecting ears 7-1 are welded at each of the four corners of the main frame. Connecting ears 7-1 have connecting bolt holes 7-2. The panel 7-6 is welded to the upper surface of the main frame. The walkway panel 7 is connected to the inner column 6-3 and the outer column 5-2 via connecting lugs 7-1 and high-strength connecting bolts 4. A walkway panel 7 is installed between each adjacent support beam 3 of the enclosure frame, and the adjacent walkway panels 7 are of different sizes, that is, the adjacent walkway panels 7 are two walkway panels 7 with the same structure but different height and width dimensions. This ensures that when two adjacent walkway panels 7 are connected to the same outer column 5 or inner column 6, they can be cross-embedded and connected based on the same bolt hole and high-strength connecting bolt 4.

[0038] The connecting ear 7-1 measures 80×2×120mm. The longitudinal keel 7-3, cross keel 7-4, and transverse keel 7-5 of the walkway are all made of steel plates that are 20mm high and 2mm thick. The walkway panel 7-6 is made of steel plate that is 1mm thick.

[0039] like Figure 8 , 9 As shown, the enclosure panel 8 is composed of two identical enclosure panels welded together. Each enclosure panel has a planar dimension of 1500×750mm and includes enclosure panel slot posts 8-1, enclosure panel top and bottom joists 8-2, enclosure panel middle joists 8-3, and enclosure panel protective mesh 8-4. The enclosure panel slot posts 8-1, enclosure panel top and bottom joists 8-2, and enclosure panel middle joists 8-3 are welded together to form the main frame of the enclosure panel. The enclosure panel protective mesh 8-4 is welded and installed within this main frame. The dimensions of the enclosure panel slot posts 8-1 match the outer post slots 5-1, and the enclosure panel 8 is embedded between adjacent outer posts 5 through the enclosure panel slot posts 8-1.

[0040] like Figure 10 As shown, the flap 9 includes flap slot posts 9-1, flap keel beam 9-2, flap body 9-3, flap hinge 9-4, and lifting rod 9-5. Flip slot posts 9-1 are welded to both ends of the flap keel beam 9-2. The dimensions of the flip slot posts 9-1 match the inner column slots 6-1. The flap 9 is embedded between adjacent inner columns 6 via the flip slot posts 9-1. Multiple flap bodies 9-3 (preferably three in this embodiment) are installed on one side of the flap keel beam 9-2 via the flap hinge 9-4. The flap bodies 9-3 can rotate around the flap keel beam 9-2. A lifting rod 9-5 is also welded to the middle of the flap keel beam 9-2 to facilitate the disassembly and lifting of the flap 9.

[0041] In this embodiment, to more clearly demonstrate the enclosure structure, Figure 1 In the drawing, only one section of each of the following is drawn: walkway slab 7, enclosure slab 8, and flap 9.

[0042] The construction method for the steel beam-attached integral hoisted enclosure frame described in this invention includes the following steps:

[0043] According to the actual construction requirements, holes are laid out and drilled on the corresponding steel beam stiffening plates 2 and the retaining frame support beams 3. After the holes are drilled, steel plates of the same diameter and material thickness are welded for reinforcement. According to the spacing requirements of the retaining frame support beams 3, two types of steel beam stiffening plates 2 are welded at intervals on the steel beam body 1. Then, each retaining frame support beam 3 is connected to the steel beam stiffening plates 2 using high-strength connecting bolts 4. The outer columns 5 and inner columns 6 are fabricated according to the design. The outer column base connecting ear plates 5-4 and the inner column base connecting ear plates 6-4 are snapped onto the retaining frame support beams 3 and connected with high-strength connecting bolts 4. Then, the installed steel beam body 1, steel beam stiffening plates 2, retaining frame support beams 3, outer columns 5, and inner columns 6 are hoisted and placed on the main building structure frame as a whole.

[0044] Then, refer to Figure 1 , 11 As shown, walkway panels 7 are installed between adjacent retaining frame support beams 3. The connecting lugs 7-1 of the walkway panels 7 are connected to the outer column body 5-2 and the inner column body 6-3 using high-strength connecting bolts 4. Flip plates 9 are installed between adjacent inner columns 6. The flip plate slotted column 9-1 is inserted into the inner column slot 6-1, and the flip plate 9 is overlapped with the side of the main building structure. Enclosing panels 8 are installed between the outer columns 5. The enclosing panel slotted column 8-1 is inserted into the outer column slot 5-1. Then, steel bearing plates are laid between the steel beam bodies 1, and the concrete floor slab 10 structure is constructed.

[0045] The embodiments described above are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essence of the present invention shall fall within the protection scope of the present invention.
