[0049] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0050] In the description of the present application, it should be understood that the directions or positional relationships indicated by the directions, such as up, down, front, back, left, right, etc., are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application. If there is a description of first or second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or indicating relative importance in time or implicitly indicating the number of the indicated counting features or implicitly indicating the order of the indicated technical features.

[0051] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0052] During the construction process, after the basement construction is completed and the construction scaffolding is removed, due to the need for upper structure hoisting, a large crawler crane is required to walk or stand on the basement top floor to lift components. Since the crawler crane load was not considered during the structural design of the basement, the floor slab and concrete beams of the basement top cannot meet the force requirements, so the original structure must be reinforced. Based on this, the present application proposes a basement operation reinforcement structure and construction method, which can improve the load capacity of the basement top.

[0053] Reference Figure 1 and Figure 2 As shown, in the first aspect, the embodiment of the present application proposes a basement operation reinforcement structure, which is applied to a basement, and the basement includes a basement top plate 100; the basement operation reinforcement structure includes:

[0054] A roadbed box 200, wherein a plurality of roadbed boxes 200 are provided, and the plurality of roadbed boxes 200 are arranged in a row on the upper surface of the basement top plate 100;

[0055] The anti-top steel support component 300 has two ends connected to the basement top plate 100 and the basement ground 400 respectively. A plurality of anti-top steel support components 300 are provided and distributed in the basement according to preset distribution intervals; the distribution intervals are obtained by modeling and calculating the building model corresponding to the basement.

[0056] Therefore, a roadbed box 200 is laid on the upper surface of the basement top plate 100 where the crawler crane is traveling, so that the load generated by the crawler crane is widely and evenly spread from the crawler belt to the entire basement top plate 100. Anti-top steel support components 300 are arranged at a certain interval on the lower surface of the basement top plate 100, so that the upper surface load of the basement top plate 100 is effectively transmitted to the ground 400 of the basement through the anti-top steel support components 300. And because the anti-top steel support components 300 are obtained by modeling and calculation through the building model, the distributed anti-top steel support components 300 can better play a supporting role and reduce the probability of deformation of the basement top plate 100. Therefore, the basement operation reinforcement structure of the embodiment of the present application improves the load capacity of the basement top plate 100.

[0057] It should be noted that the roadbed box 200 is usually a square structure with inconsistent length and width. The number of roadbed boxes 200 can be determined according to the size information and specifications of the basement top plate 100. The specifications of the roadbed box 200 are determined by the model of the crawler crane. For example, the roadbed boxes 200 are laid horizontally, that is, the shorter side (i.e., the width side) of the roadbed boxes 200 are laid in rows along the walking direction of the crawler crane, and the following can be obtained: Figure 3 The distribution of the roadbed box 200 is shown, wherein Figure 3 The middle arrow indicates the walking direction.

[0058] It should be noted that the anti-top steel support component 300 at least includes a steel column support body 310, and the steel column support body 310 can be selected from channel steel, H-shaped steel, box-shaped steel, etc., and this embodiment of the application does not limit this.

[0059] It should be noted that the basement top plate 100 includes a floor plate 120 and a plurality of beams and columns 110 distributed laterally for bearing loads. Vertically distributed beams and columns 110 supporting the basement top plate 100 are also provided in the basement. The vertically distributed beams and columns 110 and the horizontally distributed beams and columns 110 are connected to form the main load-bearing structure of the basement. Some of the anti-top steel support components 300 are located under the horizontally distributed beams and columns 110, and some are distributed on the floor plate 120 between two adjacent horizontally distributed beams and columns 110. The intervals between any two adjacent anti-top steel support components 300 can be the same or different, and are specifically set according to the spacing obtained by modeling calculation.

[0060] Understandably, referring to Figure 3 As shown, the long side of each roadbed box 200 is perpendicular to the direction in which the crawler crane travels on the upper surface of the basement top plate 100. By arranging the long side of the roadbed box 200 perpendicular to the direction in which the crawler crane travels, the number of roadbed boxes 200 laid on the upper surface of the basement top plate 100 is sufficient, thereby improving the load capacity of the basement top plate 100.

[0061] Understandably, referring to Figure 4 and Figure 5 As shown, the anti-top steel support component 300 includes a steel column support body 310, a pad 320 and a plurality of wedges 330. The two ends of the steel column support body 310 are respectively connected to the basement top plate 100 and the pad 320. The pad 320 is set on the ground 400. The plurality of wedges 330 are detachably connected to the pad 320 and are circumferentially distributed around the steel column support body 310. The wedges 330 are used to fill the gap between the pad 320 and the steel column support body 310. The steel column support body 310 is positioned by setting the wedges 330 and the pad 320, and then the gap between the pad 320 and the steel column support body 310 is filled by the wedges 330, so that the two ends of the steel column support body 310 are respectively pressed against the basement top plate 100 and the ground 400, thereby reducing the probability that the basement top plate 100 is pressed against the steel column support body 310 only after deformation.

[0062] It should be noted that a wedge 330 is provided on each side of the steel column support body, and multiple wedges 330 can be provided on each side, but there is at least a pair of wedges 330 on opposite sides that are symmetrically arranged, and then when the wedges 330 are used to fill the gaps, knocking the symmetrical wedges 330 at the same time can maintain the stability of the steel column support body 310.

[0063] It is understandable that a connector 500 is connected between two adjacent counter-top steel support components 300 located in the same row. By providing the connector 500, the counter-top steel support components 300 are more stable, and the load capacity of the basement top plate 100 is further improved.

[0064] For example, refer to Figure 2 As shown, the connector 500 is configured as a steel connector 500. The steel connector 500 is connected to the steel column support body 310.

[0065] It is understandable that part of the anti-top steel support components 300 are located below the beams and columns 110 of the basement top plate 100, and the cross-sectional area of ​​the anti-top steel support components 300 located at the beams and columns 110 is larger than the cross-sectional area of ​​the anti-top steel support components 300 located at other positions of the basement top plate 100. By setting the cross-sectional area of ​​the anti-top steel support components 300 located below the beams and columns 110 to be larger, the beams and columns 110 that are subjected to more force can be better supported, and the load capacity of the basement top plate 100 can be further improved.

[0066] Reference Figure 6 As shown, in a second aspect, an embodiment of the present application provides a construction method for a basement work reinforcement structure, which is applied to any basement work reinforcement structure of the first aspect, and the construction method includes:

[0067] Step S100: obtaining estimated parameters of the anti-top steel support component 300 to be installed.

[0068] It should be noted that an estimated parameter can be roughly estimated according to the area of ​​the basement top plate 100 and the specifications of the crawler crane. The estimated parameters include the number, distribution interval and hardware parameters of the steel column support body 310 in the counter-top steel support component 300, and the hardware parameters correspond to the hardware selection (different hardware selections have different materials or cross-sectional areas).

[0069] Step S200: Establish a building model based on the estimated parameters and the basement.

[0070] It should be noted that modeling can be performed using modeling software.

[0071] Step S300, by adjusting the building model to meet the preset conditions, the construction parameters of the anti-top steel support component 300 are obtained, and the construction parameters include the construction quantity of the anti-top steel support component 300, the distribution interval between any two adjacent anti-top steel support components 300, and hardware parameters.

[0072] It should be noted that by manually adjusting the distribution interval, quantity and hardware parameters of the building model in the modeling software, and based on the load parameters of the adjusted building model, it can be checked whether the adjustment is in place (that is, whether the preset conditions are met).

[0073] Step S400 , determining the hardware selection of the anti-top steel support component 300 according to the hardware parameters and distributing a plurality of anti-top steel support components 300 corresponding to the construction quantity under the basement top plate 100 according to the distribution intervals.

[0074] Step S500 , arranging a plurality of roadbed boxes 200 in rows on the upper surface of the basement top plate 100 .

[0075] It is understandable that the preset conditions include at least one of the following:

[0076] The maximum stress ratio of the beams and columns 110 of the basement top plate 100 is less than 1;

[0077] The maximum verification ratio of the anti-top steel support component 300 is less than 1;

[0078] The over-provision coefficient of the concrete slab of the basement top slab 100 is greater than 1;

[0079] The maximum crack of the basement ceiling 100 is less than 0.2 mm.

[0080] For example, refer to Figure 7As shown, when the maximum stress ratio of the concrete beam column 110 is adjusted to 0.38, the maximum verification ratio of the steel column support body 310 is 0.48, the over-matching coefficient of the concrete plate is set to 1.7, and the maximum crack of the basement top plate 100 is 0.06mm, it means that the load-bearing structure of the basement meets the force requirements. At this time, the distribution interval, cross-sectional area and number of steel column support bodies 310 set in the building model can be selected and construction can be carried out with reference to the adjusted building model.

[0081] It is understandable that step S500, arranging multiple roadbed boxes 200 in rows on the upper surface of the basement top plate 100, includes: obtaining the walking direction of the crawler crane on the basement top plate 100; obtaining a first length value of the basement top plate 100 in the walking direction; calculating the number of roadbed boxes 200 in each column based on the first length value and the width value of the roadbed box 200; determining the number of rows of the roadbed boxes 200 based on the second length value of the roadbed box 200 and the width value of the basement top plate 100; and laying multiple roadbed boxes 200 according to the number of rows and the number of rows.

[0082] For example, assuming that the first length value is l1, the second length value of the roadbed box 200 is l1, and the width value is d1; the width of the basement top plate 100 perpendicular to the walking direction is d; then the number of columns of each column of the roadbed box 200 is num1=l / d1, and the number of columns of the roadbed box 200 is num2=d2 / l1. The total number of roadbed boxes 200 is num1*num2.

[0083] It is understandable that the anti-top steel support component 300 includes a steel column support body 310, a pad 320 and a plurality of wedges 330. In step S400, the plurality of anti-top steel support components 300 are distributed on the lower surface of the basement top plate 100 according to the distribution interval, including:

[0084] (1) The pads 320 are fixed to the floor 400 of the basement at distributed intervals.

[0085] (2) A plurality of notches 330 are spot welded and fixed on the pad 320 , so that the plurality of notches 330 enclose an installation space for the steel column support body 310 and at least one notch 330 is disposed on each side of the steel column support body 310 .

[0086] It should be noted that there is at least one pair of symmetrically arranged wedges 330 located on opposite sides of the steel column support body 310. At least one wedge 330 is arranged on each side of the steel column support body 310. The wedge 330 can be simply fixed by spot welding and can be easily removed later.

[0087] (3) Place one end of the steel column support body 310 in the installation space and remove the solder on the wedge 330.

[0088] By spot welding the wedge 330 on the pad 320, the wedge 330 can be fixed so that the position of the wedge 330 will not be moved when the steel column support column body is adjusted. After the position of the steel column support column body is determined, the steel column support column body and the basement ceiling 100 can be further tightened by removing the solder.

[0089] (4) The wedges 330 which are oppositely arranged and have been free of solder are simultaneously driven into the gap between the pad 320 and the steel column support body 310, so that the other end of the steel column support body 310 is pressed tightly against the basement ceiling 100.
