Abstract
Description
Technical Field
[0001] The present application relates to the technical field of supporting equipment, and in particular to a large-diameter steel pipe pile supporting device. Background Art
[0002] During the construction of river-spanning bridges, river filling is not permitted due to the requirement for water flow through the river channel. Consequently, the construction of cast-in-place box girders across the river has to adopt the steel pipe pile + Bailey beam support method. However, due to the complex geological conditions of the river channel and the irregular distribution of boulders in the riverbed, the rate of encountering boulders during the steel pipe pile installation process is nearly 100%. To address this problem, large-diameter steel pipe piles are used as the foundation for the construction supports of cast-in-place box girders across the river. This increases the porosity range, reduces the number of steel pipe piles used, reduces the probability of encountering boulders during the steel pipe pile installation process, and reduces the difficulty of construction. However, after the large-diameter steel pipe piles are constructed, I-beams are used as crossbeams on the steel pipe piles. Due to the large diameter of the steel pipe piles, the contact area between the I-beam and the steel pipe piles is small, resulting in uneven force on the steel pipe piles, which can cause instability and create safety risks. Utility Model Content
[0003] In order to solve or partially solve the problems existing in the related art, the present application provides a large-diameter steel pipe pile support device, which can effectively increase the stress-bearing area of the large-diameter steel pipe pile head and avoid slipping.
[0004] The present application discloses a large-diameter steel pipe pile support device, comprising: a steel pipe pile, wherein a positioning groove is constructed downwardly from the top of the steel pipe pile, and the positioning groove is a square groove; and an I-beam, wherein the I-beam is a double-piece I-beam, and a first anti-skid plate is constructed on both sides of the bottom of the I-beam; and a support plate; wherein the I-beam is embedded in the positioning groove, the first anti-skid plate clamps the outer groove edge of the positioning groove, and the support plate is arranged on the top of the steel pipe pile and abuts against the top of the I-beam.
[0005] Optionally, two second anti-skid plates are connected to the top of the support plate, and the two second anti-skid plates form a positioning groove.
[0006] Optionally, the four bottom connecting reinforcement ribs of the support plate are in contact with the outer wall of the steel pipe pile at the same time.
[0007] Optionally, a through hole is provided on the support plate, and four connecting reinforcement ribs are fixedly provided on the outer side wall of the steel pipe pile, and the connecting reinforcement ribs are inserted into the through hole of the support plate.
[0008] Optionally, the second anti-skid plate is fixedly arranged on the I-beam, and a hole for the second anti-skid plate to pass through is configured on the support plate.
[0009] The technical solution provided by this application may have the following beneficial effects:
[0010] This device places an I-beam into a positioning groove, and causes the first anti-slip plates on both sides to clamp onto the outer groove edge of the positioning groove to prevent it from sliding. In this way, the upper surface of the I-beam and the top surface of the steel pipe pile are located on the same plane. Finally, a support plate is placed on this plane to form a placement platform. When placing a crossbeam on the steel pipe pile, the area that was originally only in contact with the pipe edge of the steel pipe pile 1 becomes in contact with the entire bottom of the crossbeam and the support plate. The support plate is located on the pipe edge of the entire steel pipe pile, increasing the contact area between the entire crossbeam and the steel pipe pile. At the same time, due to the use of double-piece I-beams as extended support, the strength of the entire support surface of the support plate is improved, the possibility of relative sliding between the crossbeam and the support plate is reduced, and safety risks are reduced.

[0023] In response to the above problems, an embodiment of the present application provides a large-diameter steel pipe pile supporting device. The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.
[0024] like Figure 1 and Figure 2 A large-diameter steel pipe pile supporting device is shown, comprising:
[0025] A steel pipe pile 1, wherein a positioning groove 11 is formed downward from the top of the steel pipe pile 1, and the positioning groove 11 is a square groove; and
[0026] I-beam 2, which is a double-jointed I-beam, with first anti-slip plates 21 and support plates 3 constructed on both sides of the bottom of the I-beam 2;
[0027] The I-beam 2 is embedded in the positioning groove 11 , the first anti-slip plate 21 clamps the outer groove edge of the positioning groove 11 , and the support plate 3 is arranged on the top of the steel pipe pile 1 and abuts against the top of the I-beam 2 .
[0028] In this device, the double-jointed I-beam is formed by welding two I-beams. When in use, the I-beam 2 is placed in the positioning groove 11, and the first anti-slip plates 21 on both sides are clamped on the outer groove edge of the positioning groove 11 to prevent it from sliding. In this way, the upper surface of the I-beam 2 and the top surface of the steel pipe pile 1 are located in the same plane. Finally, the support plate 3 is placed on this plane to form a placement platform. When placing the beam on the steel pipe pile, the area that was originally only in contact with the pipe edge of the steel pipe pile 1 becomes in contact with the entire bottom of the beam and the support plate 3. The support plate 3 is located on the pipe edge of the entire steel pipe pile 1, which increases the contact area between the entire beam and the steel pipe pile 1. At the same time, due to the use of double-jointed I-beams as extended support, the strength of the entire support surface of the support plate 3 is improved, the possibility of relative sliding between the beam and the support plate 3 is reduced, and the safety risk is reduced.
[0029] In one embodiment, Figure 3 and Figure 4 As shown, two second anti-skid plates 5 are connected above the top of the support plate 3. The two second anti-skid plates 5 form a positioning slot, and the crossbeam is embedded in the positioning slot. In this way, the safety risk of the crossbeam sliding from the side is avoided.
[0030] In one embodiment, Figure 1 and Figure 3 As shown, four connecting ribs 4 are provided at the bottom of the support plate 3, and the connecting ribs 4 are in contact with the outer wall of the steel pipe pile 1. This not only improves the support stability of the support plate 3, but also prevents the support plate 3 from sliding on the top of the steel pipe pile 1.
[0031] In one embodiment, a more reliable method is to connect all components by welding, so that the entire structure is stable.
[0032] In one embodiment, a structure that facilitates assembly and disassembly is provided with through-holes in the support plate 3. Four connecting ribs 4 are fixedly installed on the outer wall of the steel pipe pile 1. The connecting ribs 4 are inserted into the through-holes in the support plate 3. The support plate 3 and the I-beam 2 are both movably connected to the steel pipe pile 1. The I-beam 2 is prevented from moving by the positioning groove 11 and the first anti-slip plates 21 on its sides, while the support plate 3 is prevented from moving by the connecting ribs 4. When in use, the connecting ribs 4 are provided with steps at the bottom of the support plate 3 to increase the support strength. In this way, the entire structure is easy to assemble and disassemble.
[0033] In one embodiment, a structure that is convenient for assembly and disassembly and more convenient for fixing the support plate 3 is to fix the second anti-slip plate 5 on the I-beam 2, and a hole for the second anti-slip plate 5 to pass through is configured on the support plate 3.
[0034] Finally, it should be noted that, in this document, relationships such as first and second, etc., are used solely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
