Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety passages, in particular to an assembled safety passage for dock construction. Background Art
[0002] Dock construction is generally an offshore operation. In order to facilitate the work of the operators, a spliced safety passage is generally used. That is, the longitudinal H-shaped steel is first hoisted on site using a ship, and then wooden boards or steel gratings are laid section by section as walkway boards and fixed. When the construction of a certain beam is completed, the walkway board is dismantled to the next beam to be constructed.
[0003] In the existing technology, for prefabricated safety passages, I-beams and concrete pouring are mainly used to increase the stability and load-bearing capacity of the steel. However, after the passage collapses due to the excessively heavy concrete, the foam material filled inside is difficult to overcome gravity, and thus the ability to resist wind and waves is poor. For example, the patent with publication number CN209194311U in the prior art discloses an assembled safety passage for dock construction, which is achieved by arranging side filling plates on the outside of H-shaped steel plates, arranging main filling plates between the H-shaped steel plates, filling the side filling plates and the main filling plates with foam materials with greater buoyancy, and arranging air grooves between the main filling plates and the walking base plate. When the safety passage collapses, water will first fill the air grooves to slow down the sinking speed. At the same time, the foam materials in the main filling plates and the side filling plates will make the collapsed parts float on the water surface, avoiding the situation where construction workers fall into the water and drown due to the sinking of the collapsed parts. However, concrete needs to be poured during the construction process, and I-beams are used in combination with concrete to increase the stability and load-bearing capacity of the steel. However, after the passage collapses, the foam material filled inside the overly heavy concrete will find it difficult to overcome gravity to support and float the walkway, resulting in poor safety. Utility Model Content
[0004] The purpose of the utility model is to provide an assembled safety passage for dock construction, which effectively disperses water pressure through the integrated bottom sealing setting, avoids the impact of wind and waves on the passage support beams, protects against seawater erosion and bumps, extends the service life of the passage support beams and improves stability.
[0005] In order to achieve the above effects, the technical solution of the utility model is as follows:
[0006] An assembled safety passage for dock construction includes a dock passage, which includes, from top to bottom, guardrails, passage support beams, shear walls, and caissons. An assembly cavity is formed inside the passage support beams, and a plurality of reinforcement structures are arranged in a matrix within the assembly cavity. The cavities of the reinforcement structures are filled with shock-absorbing mechanisms.
[0007] The caisson is a hollow structure, and an opening is provided on one side of the caisson close to the shear wall. When the caisson sinks to a set position, the shear wall is filled and cast together with the caisson opening to form an integrated structure.
[0008] After the caissons are fixedly connected to the shear walls in a one-to-one correspondence, a plurality of shear walls form at least two rows of support parts, and the dock guardrails are assembled on the channel support beams located on the support parts along the direction of the support parts.
[0009] Furthermore, the caisson is divided into a plurality of casting cavities by dividing pieces, and the caisson side portions and / or dividing pieces forming the casting cavities are upwardly extended with a plurality of steel extension pieces which form shear walls after casting.
[0010] Furthermore, the projection of the shear wall is located inside the caisson, and a protective edge is formed outwards of the caisson at the connection between the caisson and the shear wall.
[0011] Furthermore, the bottom of the caisson is away from the shear wall and extends toward the periphery to form an expansion cavity.
[0012] Furthermore, the reinforcement structure includes a plurality of I-shaped steel beams connected in sequence, the tops and bottoms of the I-shaped steel beams are connected in sequence, and a plurality of assembly cavities for assembling shock-absorbing mechanisms are formed in the middle.
[0013] Furthermore, the shock absorbing mechanism is a spring, which is in a compressed state and is respectively connected to the top and bottom of the I-shaped steel beam.

[0016] Furthermore, along the length direction of the shear wall, a number of triangular support steels are connected to the shear wall in a sequence of vertex connection and side connection.
[0017] The beneficial effects of the utility model are as follows:
[0018] 1. In the present utility model, the caisson is a structure with a top but no bottom. During construction, workers first dig soil along the wall of the barrel. The caisson gradually sinks due to its own gravity or external pressure, sinking as it is dug. At the same time, concrete shear walls are poured on top of the caisson. After the caisson sinks to a certain depth, it is sealed to form an integrated structure, which effectively disperses water pressure, avoids the impact of wind and waves on the channel support beams, protects them from seawater erosion and bumps, extends the service life of the channel support beams and improves stability.
[0019] 2. In the present invention, each channel support beam is spliced with the channel support beam on the other side through the connecting beam at the bottom. During operation, it is necessary to nail the bolts into the channel support beam at the other end through the connecting beam. The upper reinforcement of the bottom triangular support steel adopts screw tension and is connected to the embedded reinforcement of the channel support beam. The reserved hole of the shear wall is provided with expansion screws. Two expansion screws are provided and connected to the side of the triangular support steel and the shear wall to strengthen the fixation; on the other hand, the alloy spring steel on the inside of the I-beam has high elasticity, wear resistance and corrosion resistance.

[0027] The present invention is described in detail below with reference to the various embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in this field based on these embodiments are all within the scope of protection of the present invention.
[0028] Refer to the attached Figures 1-5As shown, the assembled safety passage used for dock construction in this embodiment includes a dock passage 1, which includes a guardrail 14, a passage support beam 13, a shear wall 12 and a caisson 11 from top to bottom. An assembly cavity is formed inside the passage support beam 13, and a plurality of reinforcing structures 15 are arranged in a matrix in the assembly cavity. The cavity of the reinforcing structure 15 is filled with a shock-absorbing mechanism 3. In this embodiment, due to the passage of vehicles, etc., the dock passage will be squeezed, etc., causing the internal reinforcing structure to deform. At this time, the shock-absorbing mechanism 3 is utilized to absorb energy to alleviate vibration and impact, thereby effectively preventing the deformation of the reinforcing structure formed by the I-beam steel beam and improving the overall strength of the dock passage.
[0029] Different from the prior art, in this embodiment, the caisson 11 is a hollow structure, and an opening is provided on one side of the caisson 11 close to the shear wall 12. When the caisson 12 sinks to the set position, the shear wall 12 is filled and cast together with the opening of the caisson 11 to form an integrated structure; thus, this arrangement effectively disperses the water pressure, avoids the impact of wind and waves on the channel support beam, protects it from seawater erosion and bumps, extends the service life of the channel support beam and improves its stability.
[0030] In this embodiment, the specific formation of the channel mainly relies on the channel support beam 3. At this time, after the caisson 11 and the shear wall 12 are fixed one by one, several shear walls 12 form at least two rows of support parts, and the dock guardrail 14 is assembled on the channel support beam 3 located on the support part along the direction of the support part.
[0031] First, the relevant introductions to the caisson and shear wall in this embodiment are as follows:
[0032] In this embodiment, the caisson 11 is divided into several casting cavities by means of partitions. The sides of the caisson 11 and / or the partitions forming the casting cavities are provided with several steel extensions extending upward, which are then cast to form shear walls. This division increases the strength of the caisson 1's main body within the cavity. The steel bars cast within the caisson 1 or welded to the main body then provide guidance and reinforcement for the subsequent casting of the shear walls, improving efficiency.
[0033] Furthermore, the projection of the shear wall 12 is located within the caisson 11, and a protective cavity is formed outwardly at the connection between the caisson 11 and the shear wall 12. Specifically, the shear wall 12 has a small cross-sectional area. When viewed from the outside, the caisson 11 is partially sheathed around the outer periphery of the shear wall 12. Therefore, in the event of an accident with the shear wall 12, the protective edge of the frame provides protection from the outer periphery.
[0034] To ensure bottom stability, the bottom of the caisson 11 extends away from the shear wall 12 and outward to form an expansion cavity. The expansion cavity of the caisson 11 now forms a larger support. Compared with a structure with a constant cross-section, the expansion of the bottom increases the bottom support force.
[0035] Secondly, we will introduce the strengthening and shock absorption:
[0036] The reinforcement structure 15 in this embodiment includes a plurality of I-shaped steel beams connected in sequence, wherein the top and bottom of the I-shaped steel beams are connected in sequence, and a plurality of assembly cavities for assembling shock-absorbing mechanisms are formed in the middle.
[0037] Specifically, the shock-absorbing mechanism 2 is a compressed spring connected to the top and bottom of the I-beam. During use, the alloy spring steel inside the I-beam is highly elastic, wear-resistant, and corrosion-resistant. Vehicles traveling on the passageway for extended periods of time can cause the I-beam to slightly bend and deform. The alloy spring steel absorbs energy, mitigating vibrations and shocks. This effectively prevents deformation of the I-beam and enhances the overall strength of the passageway.
[0038] Again, we will introduce the strengthening of the periphery.
[0039] In order to realize a longer channel, several connecting beams 3 are also included along the width direction of the channel support beam 13, which are located at the bottom of the channel support beam 13 and staggered with the shear wall 12. The connecting beams 3 are provided with limiting bolts 4 for fixedly connecting adjacent channel support beams.
[0040] Furthermore, it also includes a triangular support steel 5 connecting the adjacent shear walls 12 in the width direction of the channel support beam 13. The triangular support steel 5 is fixedly connected to the shear wall 12 through the reserved hole 6 and the expansion screw 7, thereby improving its internal strength.
[0041] To ensure uniform force in the connection, several triangular support steels 5 are connected to the shear wall 12 in a vertex connection and side connection arrangement along the length of the shear wall 12. That is, adjacent triangular support steels are connected at points and at surfaces, which provides good stability.
[0042] In this embodiment, the assembly process of the entire safety channel is as follows:
[0043] This device requires first digging out the foundation of the walkway and then pouring the foundation. After the concrete reaches the required strength, the walkway slab is removed and a channel support beam 13 is formed. Each channel support beam 13 is spliced with the channel support beam 13 on the other side through the connecting beam 3 at the bottom. During operation, the limit bolt 4 can be nailed into the channel support beam 13 at the other end through the connecting beam 3. The upper part of the triangular support steel 5 at the bottom is reinforced by screw tension and connected to the embedded steel bar of the channel support beam 13. The reserved hole 6 of the shear wall 12 is provided with an expansion screw 7. Two expansion screws 7 are provided and connected to the side of the triangular support steel 5 and the shear wall 12 to strengthen the fixation; on the other hand, the alloy spring steel on the inside of the I-shaped steel beam (i.e., the shock absorbing mechanism 2) has high elasticity, wear resistance and corrosion resistance. Vehicles driving on the channel for a long time will cause the I-shaped steel beam 15 to bend slightly. The alloy spring steel is used to absorb energy to alleviate vibration and impact, thereby effectively preventing the deformation of the I-shaped steel beam and improving the overall strength of the terminal channel.
