Description

Technical Field

[0001] This utility model relates to the field of tower crane foundation construction technology for bridge engineering, and in particular to a general-purpose prefabricated tower crane foundation. Background Technology

[0002] In bridge engineering, tower cranes are used in various processes, including pier construction, beam construction, and auxiliary structure construction. When the pier or beam is high, especially for piers in water or land-based piers with small abutments, tower crane foundations are required. Therefore, tower crane foundations are widely used in bridge engineering construction.

[0003] Currently, due to its advantages such as convenient construction, reusability, and versatility, the "steel pipe pile + steel section" structure for tower crane foundations is often used in bridge construction projects as the foundation for some small and medium-sized tower cranes.

[0004] However, precisely because of the high reusability of the "steel pipe pile + steel section" structure, the steel structure profiles with welded connections suffer a lot of irreversible damage during repeated use due to frequent welding, installation, cutting and disassembly. This brings great risks to their subsequent reuse, gradually reduces their turnover rate, and makes the construction process more complicated.

[0005] Therefore, a general-purpose prefabricated tower crane foundation is proposed. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that frequent welding or cutting of tower crane foundations with "steel pipe piles + steel sections" structures during the turnover process in the existing technology leads to insufficient welding quality and structural risks. Therefore, a general-purpose prefabricated tower crane foundation is proposed.

[0010] Preferably, the multi-bolt-hole pile top distribution beam is fixedly connected with multiple distribution beam reinforcement plates and distribution beam hand hole reinforcement plates.

[0011] Preferably, multiple reinforcing plates for the combined longitudinal beam are fixedly connected to the outer surface of the multi-bolt-hole combined longitudinal beam.

[0012] Preferably, each of the two multi-bolt-hole combined crossbeams is provided with a combined longitudinal beam limiting plate on one side, and multiple combined crossbeam reinforcing plates are fixedly connected to the multi-bolt-hole combined crossbeams. A combined crossbeam hand hole stiffening plate is fixedly connected to the side of the combined crossbeam reinforcing plate near the multi-bolt-hole combined crossbeam.

[0013] Preferably, the detachable base plate is connected to the combined longitudinal beam limiting plate by a frame combined beam fixing clamp, and the frame combined beam fixing clamp and the combined longitudinal beam limiting plate are fixed together by assembly bolts.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-8 A general-purpose prefabricated tower crane foundation includes a foundation support component 1, an adjustable frame composite beam 2, and assembly bolts 3. The foundation support component 1 includes a detachable pile cap 101. The adjustable frame composite beam 2 includes a multi-bolt hole composite longitudinal beam 201, a multi-bolt hole composite transverse beam 202, and a detachable foundation base plate 203. The detachable pile cap 101 is connected to the multi-bolt hole composite transverse beam 202 via the multi-bolt hole pile top distribution beam 102. The multi-bolt hole pile top distribution beam 102 and the multi-bolt hole composite transverse beam 202, the multi-bolt hole composite longitudinal beam 201 and the multi-bolt hole composite transverse beam 202, and the multi-bolt hole composite transverse beam 202 and the detachable foundation base plate 203 are all detachably installed via assembly bolts 3.

[0028] It should be noted that by setting up a detachable tower crane foundation and an adjustable spacing detachable foundation base plate, the problem of frequent welding or cutting of the "steel pipe pile + steel section" structure tower crane foundation during the turnover process can be solved. It can also reduce the structural risk caused by insufficient welding quality. Moreover, this structure can meet the needs of most models of small and medium-sized tower cranes on the market.

[0029] Based on the above, the foundation support 1 mainly serves as the load-bearing frame of the tower crane foundation, and its load-bearing capacity needs to be the primary consideration. During the installation of the tower crane foundation, due to the unstable soil conditions at the construction site, the penetration depth of the tower crane foundation steel pipe piles will also change continuously. Therefore, in order to reduce the losses and uncontrollable quality factors caused by repeated cutting and welding of the foundation structure due to the adjustment of the steel pipe pile length, and to reduce the construction difficulty, the foundation support 1 in this application is connected to different foundation steel pipe piles through the connecting flange 1013.

[0030] The adjustable frame composite beam 2 mainly serves as the load distribution frame of the tower crane foundation and the foundation structure matching the spacing of the tower crane legs. Its load-bearing capacity and structural dimensions are the primary considerations. During the installation of the tower crane foundation, factors such as the continuous change of the tower crane model and the adjustment of the tower crane's position according to the construction progress place greater demands on the structural dimensions, turnover performance, and turnover efficiency of the tower crane foundation. Therefore, in order to reduce the irreversible damage to the tower crane foundation structure during turnover, reduce the large number of uncontrollable human factors during the installation of the tower crane foundation, and improve the construction efficiency during the installation and dismantling of the tower crane foundation, the adjustable frame composite beam 2 in this application is connected and fixed to the foundation support 1 by assembly bolts 3 and multi-bolt-hole pile top distribution beam 102.

[0031] Specifically, a steel pipe column 1011 is fixedly installed at the bottom of the detachable pile cap 101, a steel pipe pile cap 1012 is fixed at the top of the steel pipe column 1011, a connecting flange 1013 is fixed at the bottom of the steel pipe column 1011, and multiple distribution beam reinforcement plates 1021 and distribution beam hand hole reinforcement plates 1022 are fixedly connected to the multi-bolt hole pile top distribution beam 102.

[0032] It should be noted that: the upper edge of the steel pipe column 1011 is provided with a steel pipe pile cap 1012 to connect with the movable structure, and the lower edge of the steel pipe column 1011 is provided with a connecting flange 1013 to provide the turnover of the foundation support component 1 system. The foundation support component 1 also includes a multi-bolt pile top distribution beam 102, which is fixed to the top of the detachable pile cap 101 by welding and is used for foundation load transfer and structural fixation.

[0033] Furthermore, multiple rows of bolt holes are provided on the multi-bolt-hole pile top distribution beam 102 and the multi-bolt-hole combined crossbeam 202 to accommodate different installation positions of the adjustable frame combined beam 2, thus meeting the needs of different tower crane models for tower crane foundations.

[0034] Specifically, multiple reinforcing plates 2011 are fixedly connected to the outer surface of the multi-bolt-hole combined longitudinal beam 201. Each of the two multi-bolt-hole combined crossbeams 202 has a combined longitudinal beam limiting plate 2021 on one side opposite to it. Multiple reinforcing plates 2022 are fixedly connected to the multi-bolt-hole combined crossbeam 202. A hand hole stiffening plate 2023 is fixedly connected to the side of the reinforcing plate 2022 near the multi-bolt-hole combined crossbeam 202. The detachable foundation base plate 203 is snapped into the combined longitudinal beam limiting plate 2021 by the frame combined beam fixing clamp 2031. The frame combined beam fixing clamp 2031 and the combined longitudinal beam limiting plate 2021 are fixed together by assembly bolts 3.

[0035] It should be noted that: the combined longitudinal beam limiting plate 2021 is used to limit and stabilize the multi-bolt hole combined longitudinal beam 201 during installation, and through the detachable foundation base plate 203, it can provide a reliable connection to the tower crane legs as a consumable component. The adjustable frame combined beam 2 is installed on the top of the foundation support 1 through the top of the multi-bolt hole pile top distribution beam 102 and the assembly bolts 3. The installation position can be adjusted according to different tower crane leg spacings.

[0036] Based on the above, after the holes on the multi-bolt-hole combined crossbeam 202 in the adjustable frame combined beam 2 and the multi-bolt-hole pile top distribution beam 102 in the foundation support 1 are accurately aligned, the assembly bolts 3 can be installed by tightening the wrench to achieve the connection and fixation between the adjustable frame combined beam 2 and the foundation support 1.

[0037] Furthermore, based on the above, the multi-bolt-hole combined longitudinal beam 201 and the multi-bolt-hole combined transverse beam 202 are the main load-bearing components of the adjustable frame combined beam 2. The multi-bolt-hole combined transverse beam 202 is provided with multiple rows of bolt holes, which can meet the different installation positions of the multi-bolt-hole combined longitudinal beam 201, so as to meet the structural dimensions of different adjustable frame combined beams 2, thereby realizing the use of different tower crane models for the tower crane foundation.

[0038] Furthermore, the combined longitudinal beam limiting plate 2021 installed on the multi-bolt-hole combined crossbeam 202 achieves different installation positions of the multi-bolt-hole combined longitudinal beam 201 through different spacing, thereby realizing multiple structural dimensions of the adjustable frame combined beam 2;

[0039] The multi-bolt-hole combined longitudinal beam 201 is connected to the combined longitudinal beam limiting plate 2021 by assembly bolts 3, thereby realizing the connection between the multi-bolt-hole combined longitudinal beam 201 and the multi-bolt-hole combined crossbeam 202.

[0040] Furthermore, the detachable foundation base plate 203, as a vulnerable component connected to the tower crane legs, is connected to the multi-bolt-hole combined longitudinal beam 201 and multi-bolt-hole combined transverse beam 202 via assembly bolts 3 and frame combination beam fixing clamps 2031, thereby achieving connection with the adjustable frame combination beam 2 to realize a reliable connection between the tower crane and the entire tower crane foundation.

[0041] The detachable base plate 203 is connected to both the multi-bolt-hole combined longitudinal beam 201 and the multi-bolt-hole combined transverse beam 202, which can increase the structural integrity and completeness of the adjustable frame combined beam 2.

[0042] Furthermore, the detachable base plate 203 also includes a limiting groove, which can provide the conditions for installing countersunk bolts when bolting the tower crane legs, and can also realize the temporary limiting function when installing the tower crane legs.

[0043] First, reliably connect the tower crane outriggers to the detachable foundation base plate 203. Then, place the detachable foundation base plate 203 at the designated position on the adjustable frame combination beam 2, align the bolt holes, and install the frame combination beam fixing clamp 2031 on the multi-bolt hole combination longitudinal beam 201 and the multi-bolt hole combination transverse beam 202. After aligning the holes, use a tightening wrench to install the assembly bolts 3, thereby achieving a reliable connection between the tower crane and the entire tower crane foundation.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
