Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a hoisting construction support structure and construction method. Background Technology

[0002] Nowadays, steel structures are increasingly involved in building construction, which involves the hoisting of steel components. If existing tower cranes cannot meet the hoisting requirements due to insufficient lifting capacity or excessive distance, truck cranes are needed to travel on the structural floor slabs and carry out the hoisting.

[0003] Chinese patent document CN119083737A discloses a method for hoisting a truck crane, comprising: setting up the outriggers of the truck crane on a floor slab, with the outriggers positioned directly above a structural beam, so that the reaction force of the outriggers acts on the structural beam. If there is no structural beam below the outriggers, a transfer steel beam is installed between the structural beams in front of and behind the outriggers, supporting the outriggers on the transfer steel beam, and the force of the outriggers is transmitted to the front and rear structural beams through the steel beam.

[0004] However, in the existing technology, if the truck crane needs to move to another location on the floor after completing construction at one location, it is necessary to reinstall the transfer steel beam at the location to be constructed. Then, the truck crane is lifted by a tower crane onto the transfer steel beam and structural beam at the location to be constructed. The construction steps are relatively complicated, and the installation of the transfer steel beam also increases the construction cost and time. In addition, if the structural floor slab has insufficient load-bearing capacity, it is not possible to move freely on the floor slab. Summary of the Invention

[0005] In view of this, the present invention provides a hoisting construction support structure and construction method to solve the problem of poor mobility of truck cranes in the prior art when constructing on floor slabs.

[0006] In a first aspect, the present invention provides a hoisting construction support structure, comprising: a main support frame for detachably installing on a structural beam on a floor slab, wherein the structural beam is used for installation on a fixed column; The main support frame includes: a support member and a support arm detachably connected to the support member. The support member is arranged horizontally, and the upper end face of the support member is used for the truck crane to travel along the length direction. Support arms are provided on both end faces of the support member in the width direction. The support arms extend outward along the width direction of the support member and are spaced apart along the length direction of the support member. The lower end of the support arm abuts against the structural beam and / or against the fixed column. At least two transfer beams are provided, which are symmetrically arranged on both sides of the support member in the width direction. The two ends of the transfer beams in the length direction are detachably connected to the two adjacent support arms respectively, and the outriggers of the truck crane abut against the upper end face of the transfer beams.

[0007] By installing multiple support arms on the support components of the main support frame, the lower ends of the support arms can abut against the structural beams of the floor slab. After the truck crane completes the lifting operation on the support components of the main support frame, when it needs to be moved, the truck crane moves to the new transfer beam position, and the outriggers of the truck crane abut against the upper surface of the transfer beam to continue the lifting operation. This enables the truck crane to move quickly on the floor slab without dismantling the main support frame, only the truck crane needs to be moved, thus improving construction efficiency.

[0008] In one alternative embodiment, the support includes a frame and a roadbed box, the roadbed box being fixedly mounted on the frame.

[0009] By fixing the roadbed box onto the frame, the truck crane can travel on the upper surface of the support after the support is installed. At this time, there is no need to use other crane equipment to move the truck crane. The truck crane can travel to the next position on its own, which can save construction time and improve construction efficiency.

[0010] In one optional embodiment, the frame includes: a plurality of first fixed rods and a plurality of second fixed rods, the first fixed rods being arranged parallel to each other at intervals, the second fixed rods being perpendicular to the first fixed rods, the two ends of the second fixed rods being detachably connected to two adjacent first fixed rods respectively, and the conversion beam being arranged parallel to and at intervals with the second fixed rods.

[0011] By setting the frame as multiple first fixed rods and multiple second fixed rods, and using the first fixed rods and second fixed rods to detachably connect to form the frame, the first fixed rods, second fixed rods and transfer beams can be transported to the floor slab during installation, and then spliced ​​and installed on the floor slab, which greatly improves the construction efficiency. At the same time, after completion, it can be disassembled into individual parts and units, which also facilitates its transportation and subsequent assembly operations.

[0012] In one optional embodiment, a third fixing rod is provided at the midpoint of the length direction of two adjacent second fixing rods, and the third fixing rod is fixedly connected to the second fixing rod.

[0013] By setting a third fixing rod, the structural strength of the frame in the middle position can be enhanced, ensuring that the frame can provide stable support for the truck crane when it is in motion.

[0014] In one alternative embodiment, the system further includes a roadbed box, which is mounted on the support member, and the truck crane travels on the roadbed box.

[0015] By installing a roadbed box on the support structure, the roadbed box can transfer the pressure of the truck crane traveling to the support structure, thus preventing the truck crane from directly acting on the structural floor slab.

[0016] Secondly, a construction method is also provided, including: Install the main support frame on the ground; After assembly, tower crane equipment is used to place the assembled main support frame and the support arm on the main support frame onto the floor slab, with the lower end of the support arm abutting against the structural beam; The truck crane is placed onto the main support frame using the tower crane equipment. The truck crane then travels back and forth along the length of the main support frame, with its outriggers abutting against the transfer beam.

[0017] By following the steps described above, a main support frame can be installed on the floor slab, allowing the truck crane to carry out construction work on the main support frame. The outriggers of the truck crane abut against the transfer beam, and the lifting load of the truck crane is transferred to the support arm through the transfer beam, and then to the structural beam through the support arm. Following the above steps, the truck crane can move on the floor slab, improving construction efficiency.

[0018] In one optional embodiment, the main support frame includes a first fixed rod, a second fixed rod, and a third fixed rod. The second fixed rod and the third fixed rod are assembled on the ground, and the assembled second fixed rod and the third fixed rod are hoisted onto the floor slab. The assembled second fixed rod, the third fixed rod, and the first fixed rod are then installed together to form the main support frame.

[0019] By setting the main support frame as an integral frame structure consisting of a first fixed rod, a second fixed rod, and a third fixed rod, it is easier to install and disassemble it, while ensuring that it has sufficient structural strength to withstand the weight of the truck crane and construction loads during construction.

[0020] In one optional embodiment, the first fixing rod and the second fixing rod enclose a frame, and a roadbed box is provided on the upper end surface of the frame.

[0021] By setting a roadbed box on the upper surface of the frame, the weight can be reduced while ensuring structural strength.

[0022] In one optional embodiment, the first fixing rods are arranged parallel to each other, and the second fixing rod is placed between two adjacent first fixing rods. The two ends of the second fixing rod abut against the first fixing rods respectively. The first fixing rods and the second fixing rods are installed and fixed. The transition beam is arranged parallel to each other on one side of the second fixing rod, and the two ends of the transition beam in the length direction are fixed to two adjacent first fixing rods respectively.

[0023] After installing the first and second fixed rods, a "well" shaped frame is formed. The outriggers of the truck crane are supported by the conversion beam. The "well" shaped frame can adapt to various wheelbases of different building structures, allowing the truck crane to have greater load-bearing capacity and use less material without damaging the original building structure.

[0024] In one optional implementation, after the first fixing rod, the second fixing rod, and the third fixing rod are installed, stress analysis is performed on the hoisting construction support structure.

[0025] Stress analysis can be conducted before construction to predict the stress conditions of the hoisting support structure and the safety of the substructure during actual construction, determining whether it can meet the load requirements generated by the crane's movement and hoisting operations. If the stress analysis results show weak points in the structure, adjustments and optimizations can be made to the specifications and connection methods of the first, second, and third fixing rods, such as increasing their wall thickness. Adjusting the support arm's pier position ensures sufficient safety for the entire hoisting support structure and the substructure during construction, guaranteeing smooth construction and preventing interruptions or accidents due to structural stress issues. These stress analyses are performed in advance based on specified crane products and common substructure dimensions, designing a support structure that meets the requirements of crane operation and substructure load-bearing capacity, enabling prefabricated assembly for application in actual construction plans.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The following is combined Figures 1 to 12 The following describes embodiments of the present invention.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, according to an embodiment of the present invention, a hoisting construction support structure is provided, including: a main support frame and a transfer beam 3. The main support frame is detachably installed on a structural beam in a floor slab. The structural beam is horizontally arranged, and both ends of the structural beam are connected to vertically arranged structural columns. The transfer beam 3 is used to support the outriggers 10 of a truck crane 9. The main support frame includes: a support member 1 and support arms 2. The support member 1 is horizontally arranged, and its upper end face is used for the truck crane 9 to travel along the length direction of the main support frame. Support arms 2 are provided on both end faces of the support member 1 in the width direction. The support arms 2 extend outward along the width direction of the support member 1, and multiple support arms 2 are spaced apart along the length direction of the support member 1. The lower ends of the support arms 2 abut against the structural beam.

[0032] Specifically, the support arm 2 is an H-beam, prefabricated according to the dimensions of the main support frame, and arranged along the length of the support member 1 according to the actual dimensions of the mesh structural beam. Two support arms 2 can be arranged in parallel. Alternatively, as an alternative implementation, the main support frame can also be configured as two diagonally oriented beams along its length, with the support arms 2 also arranged diagonally.

[0033] During installation, support component 1 and support arm 2 are detachably connected. After transporting support component 1 and support arm 2 to the construction site, a suitable support arm 2 is selected according to the size of the structural column. The main support frame is then hoisted onto the structure, and support arm 2 is then secured to support component 1 with high-strength bolts. During use, the truck crane 9 is placed on the upper surface of support component 1. The weight of the truck crane 9 is transferred through support component 1 to support arm 2, then through support arm 2 to the structural beam, and finally through the structural beam to the structural column.

[0034] At least two transfer beams 3 are provided, symmetrically arranged on both sides of the support member 1 in the width direction. The two ends of the transfer beams 3 in the length direction are detachably connected to two adjacent support arms 2. In use, the outriggers 10 of the truck crane 9 abut against the upper surface of the transfer beams 3. At this time, the force exerted by the outriggers 10 of the truck crane 9 is transmitted to the support arms 2 through the transfer beams 3, and then to the structural beams through the support arms 2. At this time, the width of the main support frame is greater than the width of the truck crane 9, but less than the width of the outriggers 10 of the truck crane 9. After the transfer beams 3 are installed on the support arms 2, the width between the two symmetrical transfer beams 3 is equal to the width of the outriggers 10 on both sides of the truck crane 9. Two outriggers 10 on the same side of the truck crane 9 can simultaneously abut against the same transfer beam 3.

[0035] By installing multiple support arms 2 on the support member 1 of the main support frame, the lower end of the support arm 2 can abut against the structural beam of the floor slab. After the truck crane 9 completes the lifting operation on the support member 1 of the main support frame, when it needs to be moved, the truck crane 9 moves to the position of the new transfer beam 3, and the outriggers 10 of the truck crane 9 abut against the upper surface of the transfer beam 3 to continue the lifting operation. This enables the truck crane 9 to move quickly on the floor slab without disassembling the main support frame, only the truck crane 9 needs to be moved, thereby improving construction efficiency.

[0036] Specifically, the support arm 2 can also be detachably connected to the support member 1. The support arm 2 is threadedly connected to the support member 1 after passing through the support arm 1 with a high-strength bolt.

[0037] like Figure 2 As shown, in this embodiment, the support member 1 includes a frame 4 and a roadbed box 5 or a U-rib plate. The roadbed box 5 is welded to the frame 4. The roadbed box 5 is an iron product made of flat steel arranged at certain intervals and crossbars, and then welded and fixed. Specifically, the roadbed box 5 is welded to the frame 4, and the lower end face of the roadbed box 5 abuts against the upper end face of the frame 4. After all the roadbed boxes 5 are installed, the truck crane 9 can travel on the upper end face of the frame 4, and personnel can also walk or carry out construction on the roadbed boxes 5. After the support member 1 is installed, the truck crane 9 can travel on the upper end face of the support member 1. At this time, there is no need to use other crane equipment to move the truck crane 9. The truck crane 9 can travel to the next position by itself, which can save construction time and improve construction efficiency. It should be noted that, as an alternative implementation, the roadbed box 5 can also be replaced with a thin ribbed steel plate welded to the frame 4. Alternatively, the roadbed box 5 can be replaced with a ribbed steel plate.

[0038] Specifically, the flat steel spacing of the roadbed box 5 is 400mm, and the roadbed box 5 is made of 20mm thick plates, with the roadbed box 5 and 20mm thick plates stacked sequentially. The roadbed box 5 is welded and fixed to the upper end of the support frame for the movement of the truck crane 9.

[0039] Specifically, the dimensions of the roadbed box 5 are: width 2400mm, length 6000mm, and height 200mm. It is made of low-alloy high-strength structural steel (Q355B). The stiffening slabs of the roadbed box 5 are 160mm long and 16mm wide.

[0040] Specifically, such as Figure 1 As shown, the roadbed box 5 can also be laid on the support member 1. The area of ​​the roadbed box 5 after laying is equal to the area of ​​the support member 1, allowing the truck crane 9 to move inside the machine box on the roadbed box 5. The roadbed box 5 evenly distributes the weight of the truck crane 9 onto the support member 1.

[0041] like Figure 3As shown, in this embodiment, the frame 4 includes: multiple first fixing rods 6 and multiple second fixing rods 7. The first fixing rods 6 are arranged parallel to each other, and the second fixing rods 7 are perpendicular to the first fixing rods 6. The two ends of the second fixing rods 7 are detachably connected to two adjacent first fixing rods 6. The transfer beam 3 is arranged parallel to the second fixing rods 7. Specifically, the first fixing rods 6, second fixing rods 7, and transfer beam 3 are all H-beams. The cross-sectional dimensions of the first fixing rods 6 are H502x465x15x25, the cross-sectional dimensions of the second fixing rods 7 are H502x465x15x25, and the cross-sectional dimensions of the transfer beam 3 are H502x465x15x25. Here, 502 refers to the height of the H-beam being 502mm, the width of the H-beam being 465mm, the web thickness being 15mm, and the flange thickness being 25mm. The first fixing rods 6, second fixing rods 7, and transfer beam 3 are all made of low-alloy high-strength structural steel (material Q390B). By setting the frame 4 as multiple first fixing rods 6 and multiple second fixing rods 7, and detachably connecting the first fixing rods 6 and the second fixing rods 7 to form the frame 4, the support component 1, roadbed box 5, support arm 2, and transfer beam 3 can be transported to the floor slab during installation, and then assembled on the floor slab, which greatly improves construction efficiency. Furthermore, after completion, it can be disassembled into individual parts and units, facilitating transportation and subsequent assembly. It should be noted that, as an alternative implementation, the dimensions of the first fixing rods 6, second fixing rods 7, and transfer beam 3 can be modified according to actual needs.

[0042] Specifically, the two ends of the first fixing rod 6 are the aforementioned support arms 2, and the two ends of the first fixing rod 6 respectively abut against the structural beam.

[0043] Specifically, in this embodiment, the length of the first fixing rod 6 is 7800mm, the length of the second fixing rod 7 is 12000mm, and the length of the transition beam 3 is the same as the length of the second fixing rod 7, also 12000mm. Three second fixing rods 7 and two transition beams 3 are installed between two adjacent first fixing rods 6. One second fixing rod 7 is installed at the midpoint of the first fixing rod 6, and the other two second fixing rods 7 are symmetrically arranged on both sides of the first fixing rod 6. The distance between the two symmetrical second fixing rods 7 and the second fixing rod 7 at the midpoint is 2400mm. The two transition beams 3 are symmetrically arranged on the outermost side of the first fixing rod 6, and the distance between the transition beam 3 and the adjacent second fixing rod 7 is 1550mm.

[0044] Specifically, such as Figure 4As shown, a fixing plate is fixedly installed between the upper and lower flanges of the first fixing rod 6. The fixing plate is fixed to the web of the first fixing rod 6 by high-strength bolts. When connecting the first fixing rod 6 and the second fixing rod 7, one end of the second fixing rod 7 in the length direction abuts against the end face of the first fixing rod 6. At this time, the web of the second fixing rod 7 is aligned with the fixing plate on the first fixing rod 6. Two mounting plates are symmetrically arranged on both sides of the web of the second fixing rod 7. The mounting plates are provided with multiple through holes. Some bolts pass through the through holes of the mounting plates and the second fixing rod 7 for fixing, while other bolts pass through the through holes of the mounting plates and the fixing plates for fixing.

[0045] Specifically, such as Figure 5 , Figure 6 As shown, the connection method between the third fixing rod 8 and the second fixing rod 7 is the same as the high-strength bolt connection method between the first fixing rod 6 and the second fixing rod 7, and will not be described again in this embodiment. Additionally, the upper and lower flanges are welded. Simultaneously, welding is used to weld the gap between the third fixing rod 8 and the second fixing rod 7.

[0046] Specifically, a pier is provided at the lower end of the support arm 2. The pier has a square cross-section, is a square steel pipe with a side length of 500mm and a wall thickness of 18mm, and is made of low-alloy high-strength structural steel (material Q355B). The pier is vertically installed and is fixedly connected to the support arm 2 by welding. The lower end of the pier abuts against the structural beam.

[0047] like Figure 3 As shown, in this embodiment, a third fixing rod 8 is provided at the midpoint of the length direction of two adjacent second fixing rods 7, and the third fixing rod 8 is fixedly connected to the second fixing rod 7. The third fixing rod 8 is arranged parallel to and spaced apart from the first fixing rod 6. Two third fixing rods 8 are provided, respectively located between two adjacent second fixing rods 7, and their two ends are fixedly connected to the two adjacent second fixing rods 7. The third fixing rod 8 is an H-beam with a cross-sectional dimension of H502x465x15x25. By providing the third fixing rod 8, the structural strength of the frame 4 at the midpoint can be enhanced, ensuring that the frame 4 can stably support the truck crane 9 when it is in motion. It should be noted that, as an alternative implementation, multiple third fixing rods 8 can be provided at intervals along the length direction of the second fixing rods 7.

[0048] like Figure 2 As shown, in this embodiment, a steel beam frame 4 is installed on the structural beam, and a roadbed box 5 is installed on the steel beam frame 4.

[0049] Specifically, the dimensions of the roadbed box 5 are: length and width 2400mm, width and length 6000mm, and height 200mm. It is made of low-alloy high-strength structural steel (Q355B). The stiffening slab of the roadbed box 5 has a height of 160mm and a width of 16mm.

[0050] Specifically, such as Figure 1 As shown, the roadbed box 5 can also be laid on the support member 1. The area of ​​the roadbed box 5 after laying is equal to the area of ​​the support member 1, allowing the truck crane 9 to move inside the machine box on the roadbed box 5. The roadbed box 5 evenly distributes the weight of the truck crane 9 onto the support member 1.

[0051] like Figure 2 As shown, according to an embodiment of the present invention, another aspect provides a construction method, comprising: installing a main support frame on the ground; after assembling the main support frame, using a tower crane to place the assembled main support frame onto a floor slab, with the lower end of the support arm 2 of the main support frame abutting against a structural beam; using the tower crane to place a truck crane 9 onto the main support frame, the truck crane 9 reciprocating along the length of the main support frame; installing a transfer beam 3 in the area to be constructed, with the outriggers 10 of the truck crane 9 abutting against the transfer beam 3. Through the above steps, a main support frame can be installed on the floor slab, allowing the truck crane 9 to perform construction on the main support frame. The outriggers 10 of the truck crane 9 abut against the transfer beam 3, and the weight of the truck crane 9 is transferred to the main support frame through the transfer beam 3, and then to the structural beam through the main support frame. Following the above steps allows the truck crane 9 to move on the floor slab, improving construction efficiency.

[0052] like Figure 3 As shown, in this embodiment, the main support frame includes a first fixing rod 6, a second fixing rod 7, and a third fixing rod 8. The second fixing rod 7 and the third fixing rod 8 are assembled on the ground, then hoisted onto the floor slab, and finally installed with the first fixing rod 6 to form the main support frame. By setting the main support frame as an integral frame 4 structure composed of the first fixing rod 6, the second fixing rod 7, and the third fixing rod 8, it is easier to install and disassemble, while ensuring sufficient structural strength to withstand the weight of the truck crane 9 and construction loads during construction.

[0053] like Figure 3 As shown, in this embodiment, the first fixing rod 6 and the second fixing rod 7 enclose a frame 4, and a third fixing rod 8 is installed at the middle position of the second fixing rod 7. A roadbed box 5 is installed on the main support frame to form a plane for the movement of the truck crane 9. By setting the roadbed box 5 on the main support frame, the weight can be reduced while ensuring structural strength.

[0054] As shown in the figure, in this embodiment, the first fixing rods 6 are arranged in parallel intervals, and the second fixing rods 7 are placed between two adjacent first fixing rods 6. The two ends of the second fixing rods 7 abut against the first fixing rods 6 respectively. The first fixing rods 6 and the second fixing rods 7 are installed and fixed. The transition beams are arranged in parallel intervals on one side of the second fixing rods 7, and the two ends of the transition beams in the length direction are fixed to two adjacent first fixing rods 6 respectively. After installing the first fixing rods 6 and the second fixing rods 7, a "well"-shaped frame 4 is formed. The outriggers 10 of the truck crane 9 are supported by the transition beams 3. The "well"-shaped frame 4 can adapt to various wheelbases of different building structures, allowing the truck crane 9 to have greater load-bearing capacity and less material usage without damaging the original building structure.

[0055] Specifically, after the installation of the first fixing rod 6, the second fixing rod 7, and the third fixing rod 8, a stress analysis is performed on the hoisting construction support structure. This stress analysis allows for pre-construction analysis, predicting the stress conditions of the hoisting construction support structure during actual construction and determining whether it can meet the load requirements generated by the movement and hoisting operations of the truck crane 9. If the stress analysis results show weak points in the structure, the specifications and connection methods of the first fixing rod 6, the second fixing rod 7, and the third fixing rod 8 can be adjusted and optimized in a timely manner. For example, the wall thickness of the fixing rods can be increased, or higher-strength connectors can be used to ensure sufficient safety of the entire hoisting construction support structure during construction, guaranteeing smooth construction and avoiding construction interruptions or safety accidents due to structural stress problems. The main reason is that through calculation and analysis, the specifications of the pre-selected support component 1 can be used for operations on the corresponding column spacing structure on a crane with a specific lifting capacity. If the construction plan involves truck crane operations on floor slabs under these conditions, the corresponding support component 1 can be directly selected and reused, which is convenient and quick.

[0056] like Figure 1 , Figure 8 , Figure 9 The image shows an example of a main support frame with a width of 12 meters provided in this embodiment. The lifting capacity of the truck crane 9 is 130 tons, and the support height is 60 mm. The main support frame and transfer beam 3, constructed according to the above steps, have a maximum combined stress of 84.5 MPa during construction, which is less than the theoretical maximum stress value of 330 MPa, meeting the construction requirements. The maximum shear stress during construction is 104 N, which is less than the theoretical maximum shear stress, also meeting the construction requirements. During the construction of the truck crane 9, the maximum vertical displacement of the main support frame is 15.8 mm, meeting the construction requirements.

[0057] like Figure 10 , Figure 11 , Figure 12The image shows an example of a main support frame with a width of 9 meters provided in this embodiment. The lifting capacity of the truck crane 9 is 130 tons, and the height of the support pier is 60 mm. The main support frame and transfer beam 3 constructed according to the above steps have a maximum combined stress of 268 MPa, which is less than the theoretical maximum stress value of 330 MPa, meeting the construction requirements. The maximum shear stress is 43 N, which is less than the theoretical maximum shear stress, meeting the construction requirements. The maximum vertical displacement is 27.5 mm.

[0058] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
