Description

Technical Field

[0001] This invention belongs to the field of bridge engineering, specifically a convenient method for constructing a high pier cap beam construction platform. Background Technology

[0002] In the construction of high piers in bridge engineering, the construction of the cap beam working platform is a crucial link in ensuring construction safety and progress. This type of platform typically needs to be erected outside the completed pier (pile) structure. The core technical requirement is to establish a reliable support structure capable of safely bearing various loads from construction personnel, equipment, and materials. Traditional methods often involve pre-embedded corbels or using steel cantilever beams on the pier as the main load-bearing foundation, upon which distribution beams and scaffolding platforms are then erected.

[0003] However, a significant drawback exists in existing technologies: the connection between the platform structure and the piers often relies on a single force transmission path. For example, the entire load is borne solely by the shear resistance of embedded parts or the bending resistance of cantilever beams. Under complex and alternating construction loads, this connection method is prone to stress concentration, leading to insufficient connection reliability and posing certain safety hazards. Furthermore, uneven distribution of support points on the platform's superstructure can easily cause localized deformation, affecting overall stability and making it difficult to fully meet the high standards of safety and stability required for high pier cap beam construction. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a convenient high-pier cap beam construction platform to solve the issues of insufficient overall stability caused by the single force transmission path and significant stress concentration in the connection between the platform and the pier column in the prior art.

[0005] A convenient high-pier cap beam construction platform includes a pile body, a protrusion, a first locking component, a support platform, an I-beam, a positioning bracket, a construction frame, and a second locking component;

[0006] The protrusion is pre-embedded and fixed to the outside of the pile body. The first locking member is fixed to the outside of the pile body by expansion bolts. The support platform is snapped into the outside of the protrusion and fixed by the first locking member. The I-beam is fixedly installed on the upper side of the support platform. The positioning bracket is fixedly installed on the upper side of the I-beam. The construction frame is snapped into the positioning bracket and fixed by the second locking member.

[0007] Preferably, the protrusion is partially embedded inside the pile body;

[0008] The protrusion is block-shaped, rib-shaped, or ring-shaped, and a groove is provided on one side of the support platform to accommodate the embedded protrusion.

[0009] Preferably, the first locking member includes a locking frame, and a support rod is provided on the outer side of the locking frame;

[0010] The locking frame is fixedly installed on the outer side of the pile body through expansion bolts;

[0011] The support platform is installed on the support rod in a limited way.

[0012] Preferably, a support convex edge is fixedly installed on the outer side of the locking frame, and the support convex edge supports the bottom of the construction member.

[0013] Preferably, the positioning support member includes a connecting plate, and support steels I are fixed at both ends of the connecting plate;

[0014] The bottom of the support steel I is welded and fixed on the upper side of the I-beam, the upper edge of the support steel I is clamped on the construction member, and the construction member and the support steel I are fixed by the second locking member passing through horizontally.

[0015] Preferably, several support steels II in the shape of "soil" are arranged on the upper side of the I-beam, the bottom of the support steel II is welded and fixed on the I-beam, and the upper edge of the support steel II is clamped on the construction member.

[0016] Preferably, the construction member includes a bottom plate, and a guardrail is welded and fixed on the upper side of the bottom plate.

[0017] A method for erecting a convenient high pier cap construction platform includes the following steps:

[0018] S1. During the construction of the pile body, the convex part is embedded and fixed on the outer side of the pile body;

[0019] S2. After the pile body is formed, the first locking member is fixed on the outer side of the pile body through expansion bolts;

[0020] S3. The support platform is clamped on the outer side of the convex part and fixed by the first locking member;

[0021] S4. The I-beam is fixedly installed on the upper side of the support platform;

[0022] S5. The positioning support member is fixedly installed on the upper side of the I-beam;

[0023] S6. The construction member is clamped on the positioning support member and fixed by the second locking member.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] By pre-embedding or partially embedding convex parts with different shapes on the pile body and precisely clamping them with the grooves on the side of the support platform, an initial connection with strong shear resistance is formed; then, the support platform is limited and assisted in fixing by the first locking member, and at the same time, the support convex edge on the locking frame directly supports the bottom of the construction member, constituting multiple guarantees from vertical load-bearing to lateral limit support, making the platform foundation extremely stable;

[0026] Above the platform, the I-beam converts the fulcrum force of the support platform into a linearly distributed force; the positioning support member is welded to the I-beam through the support steel one and is transversely locked with the construction member through the second locking member to form a rigid connection; to further optimize the force, several "soil"-shaped support steels two are added to form a uniformly distributed top support surface on the I-beam together with the support steel one, effectively avoiding excessive local stress and significantly improving the overall stiffness and load-bearing uniformity of the platform;

[0027] Finally, the construction member is composed of a bottom plate and a guardrail welded thereon, which not only provides a safe working plane but also完善了高空施工的防护体系。 BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] like Figures 1 to 4 As shown:

[0039] Example 1: The present invention provides a convenient high pier cap beam construction platform, including a pile body 1, a protrusion 2, a first locking component 3, a support platform 4, an I-beam 5, a positioning bracket 6, a construction frame 7, and a second locking component 8;

[0040] The protrusion 2 is pre-embedded and fixed to the outside of the pile body 1. The first locking member 3 is fixed to the outside of the pile body 1 by expansion bolts. The support platform 4 is snapped into the outside of the protrusion 2 and fixed by the first locking member 3. The I-beam 5 is fixedly installed on the upper side of the support platform 4. The positioning bracket 6 is fixedly installed on the upper side of the I-beam 5. The construction frame 7 is snapped into the positioning bracket 6 and fixed by the second locking member 8.

[0041] As can be seen from the above, this platform securely installs the support platform 4 onto the pile body by pre-embedding the protrusion 2 on the outside of the pile body 1 and using the first locking member 3 for auxiliary fixation, thus forming a reliable load-bearing foundation.

[0042] An I-beam 5 is fixedly installed on the upper side of the support platform 4, which further extends the support range of the platform, while the positioning bracket 6 is fixed on the I-beam 5 to support the upper construction frame 7.

[0043] The construction frame 7 is snapped into the positioning support 6 and locked by the second locking piece 8, ensuring the integrity and stability of the entire construction platform during use and effectively meeting the needs of high pier cap beam construction.

[0044] Example 2: This example is basically the same as the previous example, except that the protrusion 2 is partially embedded inside the pile body 1;

[0045] The protrusion 2 is block-shaped, rib-shaped, or ring-shaped, and a groove is provided on one side of the support platform 4 to accommodate the insertion of the protrusion 2.

[0046] Specifically, such as Figure 6 As shown, the first locking member 3 includes a locking frame 31, and a support rod 32 is provided on the outer side of the locking frame 31;

[0047] The locking bracket 31 is fixedly installed on the outside of the pile body 1 by expansion bolts;

[0048] The support platform 4 is limited and installed on the support rod 32.

[0049] Specifically, a support flange 33 is also fixedly installed on the outer side of the locking frame 31, and the support flange 33 is supported on the bottom of the construction frame 7.

[0050] Specifically, such as Figure 7As shown, the positioning support member 6 includes a connecting plate 61, and both ends of the connecting plate 61 are fixed with a first support steel 62;

[0051] The bottom of the first support steel 62 is welded and fixed to the upper side of the I-beam 5, and the upper edge of the first support steel 62 is clamped on the construction frame member 7. The construction frame member 7 and the first support steel 62 are fixed by the second locking member 8 passing through horizontally.

[0052] As can be seen from the above, the convex part 2 can be partially embedded inside the pile body 1, and its shape can be block-shaped, rib-shaped or ring-shaped. At the same time, a matching groove is provided on one side of the support table 4, making the combination of the two more closely and firmly;

[0053] The first locking member 3 includes a locking frame 31 fixed on the pile body 1 by an expansion bolt, and a support rod 32 arranged outside the locking frame 31. The support table 4 is limited and installed on this support rod 32;

[0054] In addition, a support convex edge 33 is further provided on the locking frame 31, and this support convex edge 33 directly supports the bottom of the construction frame member 7, providing additional support;

[0055] The positioning support member 6 is composed of a connecting plate 61 and the first support steels 62 at both ends; the bottom of the first support steel 62 is welded to the I-beam 5, and its upper edge is used to clamp the construction frame member 7. Finally, the second locking member 8 passes through the construction frame member 7 and the first support steel 62 horizontally to complete the fixation, thus constituting a multi-level and high-stability support system.

[0056] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that, as Figure 5 shown, several "soil"-shaped second support steels 9 are further provided on the upper side of the I-beam 5. The bottom of the second support steel 9 is welded and fixed to the I-beam 5, and the upper edge of the second support steel 9 is clamped on the construction frame member 7.

[0057] Specifically, as Figure 8 shown, the construction frame member 7 includes a bottom plate 71, and a guardrail 72 is welded and fixed on the upper side of the bottom plate 71.

[0058] As can be seen from the above, several "soil"-shaped second support steels 9 are added on the upper side of the I-beam 5. The bottom of these second support steels 9 is welded and fixed to the I-beam 5, and their upper edges are used to clamp and support the upper construction frame member 7, thereby providing a more uniform and reliable force distribution;

[0059] The construction frame member 7 is jointly composed of a bottom plate 71 and a guardrail 72 welded and fixed thereon, constituting a complete safety protection.

[0060] Embodiment 4: This embodiment is basically the same as the previous embodiment, except that a method for erecting a convenient high pier cap beam construction platform includes the following steps:

[0061] S1. During pile construction, the protrusion is pre-embedded and fixed on the outside of the pile.

[0062] S2. After the pile body is formed, the first locking member is fixed to the outside of the pile body with expansion bolts;

[0063] S3. The support platform is snapped into the outside of the protrusion and fixed by the first locking member;

[0064] S4. Fix the I-beam to the upper side of the support platform;

[0065] S5. Fix the positioning bracket to the upper side of the I-beam;

[0066] S6. The construction frame is snapped into the positioning bracket and fixed by the second locking component.

[0067] As can be seen from the above, this method begins in the pile construction stage. By fixing the protrusion to the outside of the pile in advance, a precise foundation is laid for the subsequent installation of the support structure. After the pile is formed, the first locking piece is first firmly installed on the pile. Then, the support platform is snapped into the protrusion and the first locking piece is used to complete the final fixation. These two steps constitute the stable and reliable core load-bearing foundation of the entire platform.

[0068] After establishing a stable foundation, the method proceeds with the installation of the superstructure sequentially. First, the I-beams are fixed to the upper part of the support platform to extend the main load-bearing structure; then, positioning brackets are installed on the upper part of the I-beams to provide positioning and support for the erection of the upper construction platform. Finally, the construction frame components are snapped into the positioning brackets and locked using the second locking device, thus completing the construction of the entire operating platform.

[0069] In summary, this erection method, through a bottom-up and primary-secondary logical sequence, gradually completes the entire process from pile connection and main load-bearing structure construction to operating platform installation, ensuring the systematic nature of the construction process and the integrity of the finished platform, making the platform erection process safe, efficient, and with controllable quality.
