Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction technology, specifically to a Bailey bridge frame for pile foundation construction. Background Technology

[0002] Bailey bridges are an important engineering structural component. The truss beams assembled from Bailey bridges can be decomposed into planar or three-dimensional units and connected by bolts or pins. They are characterized by high strength, reusability, ease of assembly and disassembly, and convenient transportation. Bailey bridges play an important role in bridge engineering, building construction, and tunnel engineering.

[0003] Existing Bailey bridge beam systems for pile foundation construction cannot improve the longitudinal bearing capacity of the Bailey bridge beam system during construction, have poor deformation resistance, and cannot lower the center of gravity to improve stability during installation and use. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a Bailey bridge frame for pile foundation construction. This Bailey bridge frame improves the longitudinal bearing capacity of the Bailey bridge frame, enhances its resistance to deformation, lowers its center of gravity, and improves its stability during installation and use.

[0005] The technical solution adopted by this utility model to solve its technical problem is a Bailey beam frame for pile foundation construction, including tie rods, horizontal main struts, inclined main struts, enlarged foot plates and longitudinal connecting plates. The tops of the two sets of enlarged foot plates are equipped with circular foot pads at equal intervals by locking bolts. Horizontal main struts are welded between the circular foot pads, and inclined main struts are welded to the tops of the circular foot pads.

[0006] A longitudinal connecting plate is welded to the top of the inclined main support rod in the same group. A transverse expansion plate is welded at equal intervals to the top of the longitudinal connecting plate. An outer extension block is welded at equal intervals to both sides of the longitudinal connecting plate and directly opposite the transverse expansion plate.

[0007] By adopting the above technical solutions, the Bailey bridge beams used in pile foundation construction improve the longitudinal bearing capacity of the Bailey bridge beams, enhance the anti-deformation effect, lower the center of gravity, and improve the stability during installation and use.

[0008] Specifically, the enlarged foot plate has through holes at equal intervals, and tie rods are inserted into the through holes in the same group.

[0009] Specifically, both ends of the tie rod are fitted with tension nuts, and a nut anti-slip pad is fitted between the tension nuts and the enlarged foot plate.

[0010] By adopting the above technical solution, the tension nut facilitates the tightening and fixing of the tie rod, and the anti-slip pad of the nut provides an anti-slip effect.

[0011] Specifically, the outer extension block is fixed to the transverse expansion plate by mounting bolts.

[0012] By adopting the above technical solution, the transverse expansion plate is further fixed on the outer extension block, and the outer extension block is used to effectively support it, thereby improving the bending resistance.

[0013] Specifically, the inclined main strut and the horizontal main strut form an isosceles triangle structure.

[0014] Specifically, both ends of the transverse expansion plate are welded with inner diagonal braces to the inclined main support rod, and outer diagonal braces are welded to the outer side of the inner diagonal braces.

[0015] The beneficial effects of this utility model are:

[0016] (1) The Bailey beam frame for pile foundation construction described in this utility model uses two sets of enlarged foot plates to increase the contact area with the bottom pile, lower the center of gravity, and improve the stability during installation and use. The inclined main support rod and the horizontal main support rod form an isosceles triangle structure, which is the main longitudinal load-bearing structure, thereby improving the longitudinal bearing capacity of the Bailey beam frame and improving the deformation resistance.

[0017] (2) The Bailey beam frame for pile foundation construction described in this utility model uses the outer extension blocks on both sides of the longitudinal connecting plate to further stabilize the transverse expansion plate, so as to avoid the transverse expansion plate bending after being stressed and affecting its use. The inner and outer diagonal braces welded between the transverse expansion plate and the inclined main support rods on both sides increase the outer extension length of the transverse expansion plate, which makes it easier to increase the width of the erection platform.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] To improve the longitudinal bearing capacity of Bailey bridge beams in pile foundation construction, enhance their resistance to deformation, lower their center of gravity, and improve their stability during installation and use, such as... Figure 1-3 As shown, the Bailey bridge frame for pile foundation construction of this utility model includes tie rods 4, horizontal main support rods 3, inclined main support rods 8, enlarged foot plates 5 and longitudinal connecting plates 9. The tops of the two sets of enlarged foot plates 5 are each equipped with circular foot pads 2 at equal intervals by locking bolts 1. Horizontal main support rods 3 are welded between the circular foot pads 2, and inclined main support rods 8 are welded to the tops of the circular foot pads 2.

[0025] A longitudinal connecting plate 9 is welded to the top of the inclined main support rod 8 in the same group. A transverse expansion plate 10 is welded at equal intervals to the top of the longitudinal connecting plate 9. An outer extension block 11 is welded at equal intervals to both sides of the longitudinal connecting plate 9 and directly opposite the transverse expansion plate 10.

[0026] When in use, the Bailey bridge beam structure in pile foundation construction improves the longitudinal bearing capacity of the Bailey bridge beam structure, enhances its resistance to deformation, lowers the center of gravity, and improves its stability during installation and use.

[0027] For example, such as Figure 1 , 3 As shown, the present invention also includes, at equal intervals, through holes 15 on the enlarged foot plate 5, and through holes 15 in the same group of through holes 4.

[0028] When in use, the tie rod 4 facilitates the connection of the enlarged foot plate 5 into a whole, improving the stability of the bottom support.

[0029] For example, such as Figure 1 As shown, the present invention also includes a tensioning nut 7 fitted at both ends of the pull screw 4, and a nut anti-slip pad 6 fitted between the tensioning nut 7 and the enlarged foot plate 5.

[0030] When in use, the tension nut 7 is used to tighten and fix the tie rod 4, and the anti-slip pad 6 of the nut provides an anti-slip effect.

[0031] For example, such as Figure 1 , 2 As shown, the present invention also includes the outer extension block 11 being fixed to the transverse expansion plate 10 by mounting bolts 14.

[0032] In use, the transverse expansion plate 10 is further fixed to the outer extension block 11, and the outer extension block 11 is used to effectively support it, thereby improving the bending resistance.

[0033] For example, such as Figure 1 As shown, the present invention also includes an isosceles triangle structure formed by the inclined main support rod 8 and the horizontal main support rod 3.

[0034] When in use, it serves as the main longitudinal load-bearing structure, improving the longitudinal bearing capacity of the Bailey beam and enhancing its resistance to deformation.

[0035] For example, such as Figure 1 As shown, the present invention also includes inner inclined support rods 12 welded between both ends of the transverse expansion plate 10 and the inclined main support rod 8, and outer inclined support rods 13 welded to the outer side of the inner inclined support rods 12.

[0036] When in use, increasing the outward extension length of the lateral expansion plate 10 facilitates increasing the width of the platform.

[0037] In use, this utility model utilizes two sets of enlarged foot plates 5 to increase the contact area with the bottom pile body, lower the center of gravity, and improve the stability during installation and use;

[0038] The inclined main strut 8 and the horizontal main strut 3 form an isosceles triangle structure, which is the main longitudinal load-bearing structure, improving the longitudinal bearing capacity of the Bailey beam and enhancing its resistance to deformation. Furthermore, the outer extension blocks 11 on both sides of the longitudinal connecting plate 9 further stabilize the transverse expansion plate 10, preventing the transverse expansion plate 10 from bending under stress and affecting its use.

[0039] By utilizing the inner diagonal bracing 12 and outer diagonal bracing 13 welded between the two sides of the transverse expansion plate 10 and the inclined main support rod 8, the outward extension length of the transverse expansion plate 10 is increased, which facilitates increasing the width of the platform.
