Description

Technical Field

[0001] This utility model relates to the field of steel structure platform technology, and in particular to a steel structure platform for pile driver construction. Background Technology

[0002] In the construction of slope support piles, soil is usually backfilled at the toe of the slope up to the top of the pile to serve as the operating platform for the pile driving machine. However, for high slopes, a large amount of soil needs to be backfilled, which occupies a large area, has a long construction period, and is costly.

[0003] For example, Chinese utility model patent CN206941364U, with an authorization announcement date of January 30, 2018, discloses a Bailey bridge temporary bridge. Specifically, it includes multiple steel pipe piles, multiple I-beam crossbeams, multiple rows of Bailey beams, multiple I-beam distribution beams, and a bridge deck, arranged sequentially from bottom to top. A reinforcing mechanism is installed between the multiple I-beam distribution beams to enhance their structural strength. The reinforcing mechanism includes clamping components that fit against both sides of the I-beam distribution beams and two connecting pieces perpendicular to the I-beam distribution beams. Each clamping component corresponds one-to-one with an I-beam distribution beam, and the clamping components and connecting pieces are detachably and fixedly connected. Multiple sets of clamping components are connected in series through connecting pieces, thereby limiting the movement of the I-beam distribution beams and preventing them from tilting.

[0004] The existing Bailey bridge is mainly used to meet construction transportation requirements, and the various structures are rigidly connected. If this design is used as a steel platform, the large vibrations generated during pile driving and the long-term vibration loads can easily lead to the failure of the connection points, resulting in poor safety of the entire steel platform. Utility Model Content

[0005] The technical problem this utility model aims to solve is that the large vibrations generated during pile driver construction can easily lead to the failure of connection parts due to long-term vibration loads, resulting in poor safety of the entire steel platform.

[0006] To solve the above-mentioned technical problems, this utility model provides a technical solution for a steel structure platform used in pile driver construction:

[0007] The steel structure platform used for pile driver construction includes multiple columns, supports, transverse load-bearing beams, longitudinal load-bearing beams, and a top structure. The multiple columns are inserted into the soil layer, and the transverse load-bearing beams are erected on the upper part of two transversely opposite columns.

[0008] The support is disposed between the column and the transverse load-bearing beam. The support includes a first steel plate layer, a rubber pad and a second steel plate layer stacked along the height direction, and the rubber pad is sandwiched between the first steel plate layer and the second steel plate layer.

[0009] An anti-detachment rope is also connected between the transverse load-bearing beam and the column, and the anti-detachment rope extends obliquely in the height direction; the longitudinal load-bearing beam is installed on the upper side of the transverse load-bearing beam, and the top structure is set on the upper side of the longitudinal load-bearing beam.

[0010] Furthermore, the column is a steel pipe column, and the interior space above the soil layer is filled with concrete.

[0011] Furthermore, the upper part of the column is provided with a groove, the support is fixed to the bottom of the groove, and the transverse load-bearing beam is arranged in the groove and located on the upper side of the support.

[0012] Furthermore, a bolt is fixed to the upper part of the column, the bolt protruding from the upper side of the column along the height direction, the bolt passing through the first steel plate layer, the rubber pad and the second steel plate layer, and a fastening nut is also installed on the upper part of the bolt.

[0013] Furthermore, two reinforcing rods are fixedly connected between the two horizontally opposite columns, and the two reinforcing rods are arranged in a cross pattern.

[0014] Furthermore, the transverse load-bearing beam includes two I-beams, which are arranged side by side in the transverse direction and are symmetrically distributed about the central axis of the column.

[0015] Furthermore, there are at least two sets of longitudinal load-bearing beams, which are arranged laterally at intervals. Each set of longitudinal load-bearing beams includes multiple Bailey bridges, which are sequentially spliced ​​together along the longitudinal direction.

[0016] Furthermore, a reinforcing plate is fixedly connected between the transverse load-bearing beam and the Bailey bridge.

[0017] Furthermore, the top structure includes multiple transverse transfer beams and a top steel plate, with the multiple transverse transfer beams disposed on the upper side of the longitudinal load-bearing beams and the top steel plate laid on the upper side of the multiple transverse transfer beams.

[0018] Compared with existing technologies, the steel structure platform for pile driver construction disclosed in this utility model has the following advantages: This steel structure platform for pile driver construction adopts a design consisting of multiple columns, supports, transverse load-bearing beams, longitudinal load-bearing beams, and a top structure. Multiple columns are inserted into the soil, serving as the foundation for the entire platform and ensuring its stability. The transverse load-bearing beams are erected on top of two transversely opposite columns. Supports are located between the columns and the transverse load-bearing beams. Each support comprises a first layer of steel plates, a rubber pad, and a second layer of steel plates stacked together. The supports possess excellent load-bearing capacity and vibration damping performance, reliably bearing the vibration loads of the entire platform and the pile driver.

[0019] The transverse load-bearing beams are connected to the columns by anti-derailment ropes. These ropes extend obliquely in the vertical direction, acting as flexible restraints between the beams and columns to prevent relative displacement of the beams. This ensures structural reliability even under prolonged vibration loads and avoids the potential failure due to rigid connections. Furthermore, longitudinal load-bearing beams are installed above the transverse beams, with the top structure situated above them. This combination of longitudinal and transverse beams ensures the balanced stress distribution on the steel platform, thereby guaranteeing the stability and safety of the top structure as the working surface for the piling machine.

[0031] like Figures 1 to 6 As shown, a steel structure platform for pile driver construction according to an embodiment of the present invention includes multiple columns 1, supports 2, transverse load-bearing beams 3, longitudinal load-bearing beams 4, and a top structure 5. The multiple columns 1 are inserted into the soil layer, the transverse load-bearing beams 3 are erected on the upper part of two transversely opposite columns 1, and the supports 2 are set between the columns 1 and the transverse load-bearing beams 3.

[0032] The support 2 includes a first steel plate layer 21, a rubber pad 22, and a second steel plate layer 23 stacked along the height direction, with the rubber pad 22 sandwiched between the first steel plate layer 21 and the second steel plate layer 23; an anti-detachment rope 30 is also connected between the transverse load-bearing beam 3 and the column 1, and the anti-detachment rope 30 extends obliquely in the height direction; the longitudinal load-bearing beam 4 is installed on the upper side of the transverse load-bearing beam 3, and the top structure 5 is set on the upper side of the longitudinal load-bearing beam 4.

[0033] The steel structure platform used for pile driver construction adopts a design consisting of multiple columns 1, supports 2, transverse load-bearing beams 3, longitudinal load-bearing beams 4, and a top structure 5. The multiple columns 1 are inserted into the soil, serving as the foundation for the entire platform and ensuring its stability. The transverse load-bearing beams 3 are erected on top of two transversely opposite columns 1. The supports 2 are positioned between the columns 1 and the transverse load-bearing beams 3. Supports 2 consist of a first steel plate layer 21, a rubber pad 22, and a second steel plate layer 23 arranged in layers. Supports 2 possess excellent load-bearing capacity and vibration damping performance, reliably bearing the vibration loads of the entire platform and the pile driver.

[0034] Among them, an anti-derailment rope 30 is connected between the transverse load-bearing beam 3 and the column 1. The anti-derailment rope 30 extends obliquely in the height direction. The obliquely positioned anti-derailment rope 30 plays a flexible limiting role between the transverse load-bearing beam 3 and the column 1, preventing relative displacement of the transverse load-bearing beam 3 on the column 1, ensuring that the structure remains reliable even after long-term vibration loads, and avoiding the problem of possible breakage failure due to rigid connection. In addition, the longitudinal load-bearing beam 4 is installed on the upper side of the transverse load-bearing beam 3, and the top structure 5 is set on the upper side of the longitudinal load-bearing beam 4. The combination of the longitudinal load-bearing beam 4 and the transverse load-bearing beam 3 ensures the stress balance of the steel structure platform, thereby ensuring the stability and safety of the top structure 5 as the working surface of the pile driver.

[0035] In this embodiment, the column 1 is a steel pipe column, and the space above the soil layer inside the column 1 is filled with a concrete portion 11. Furthermore, the interior of the steel pipe column is also filled with coarse sand, which is located below the concrete portion 11. The stability of the column 1 is enhanced by filling with coarse sand and pouring concrete.

[0036] As a further preferred embodiment, the upper part of the column 1 is provided with a groove 13, such as... Figure 5 As shown, the support 2 is fixed to the bottom of the groove 13, and the transverse load-bearing beam 3 is set in the groove 13 and located on the upper side of the support 2. Specifically, the transverse load-bearing beam 3 is welded and fixed to the second steel plate layer 23 of the support 2, and the anti-derailment ropes 12 on both sides achieve a reliable connection between the transverse load-bearing beam 3 and the column 1.

[0037] It should be noted that a bolt 24 is fixed to the upper part of the column 1. The bolt 24 protrudes from the upper side of the column 1 along the height direction and passes through the first steel plate layer 21, the rubber pad 22, and the second steel plate layer 23. A fastening nut 25 is also installed on the upper part of the bolt 24. The bolt 24 is embedded in the concrete part 11 of the column 1, and the other end of the bolt 24 protrudes from the upper surface of the second steel plate layer 23. The fastening nut 25 fastens the first steel plate layer 21, the rubber pad 22, and the second steel plate layer 23. Sealant is applied between the inner wall of the groove 13 and the support 2, thereby ensuring the reliability of the support 2.

[0038] Two reinforcing rods 12 are fixedly connected between the two laterally opposite columns 1. The two reinforcing rods 12 are arranged in a cross pattern. The reinforcing rods 12 can be made of channel steel. Welding the reinforcing rods 12 can enhance the lateral stability between the columns 1. In addition, the transverse load-bearing beam 3 includes two I-beams 31, which are arranged side by side in the transverse direction and are symmetrically distributed about the central axis of the columns 1.

[0039] Furthermore, there are at least two sets of longitudinal load-bearing beams 4, arranged laterally at intervals. Each set of longitudinal load-bearing beams 4 includes multiple Bailey bridge frames 40, which are sequentially spliced ​​together along the longitudinal direction. Specifically, the Bailey bridge frames 40 adopt the domestically produced "321" highway bridge truss, with a length and height of 3*1.5m. The longitudinal length can be arranged according to the span of the column 1. Each set of longitudinal load-bearing beams 4 is connected by a decorative window, thereby enabling multiple Bailey bridge frames 40 to jointly form an integral structure.

[0040] In addition, a reinforcing plate 32 is fixedly connected between the transverse load-bearing beam 3 and the Bailey bridge 40, which enhances the connection strength between the Bailey bridge 40 and the transverse load-bearing beam 3. The top structure 5 includes multiple transverse transfer beams 51 and a top steel plate 52. The multiple transverse transfer beams 51 are arranged on the upper side of the longitudinal load-bearing beam 4, and the top steel plate 52 is laid on the upper side of the multiple transverse transfer beams 51.

[0041] The transverse transfer beam 51 can also be made of I-beams. A top steel plate 52 is laid on top of the transverse transfer beam 51, with the spacing based on the upper full-span scaffold, and is positioned above the Bailey bridge 40. Finally, the slope of the support pile top is trimmed to the pile top elevation, and simultaneously serves as a temporary access route for the pile driver to enter the steel platform. A steel plate is laid between the support pile top and the steel platform, allowing the pile driver to enter the steel platform from the constructed slope to carry out pile driving operations.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
