Description

Technical Field

[0001] The present invention relates to the technical field of caisson construction, and particularly relates to a steel bar binding system for a standard layer of a caisson and a construction method thereof. Background Art

[0002] A caisson is an engineering facility used for underwater operations, usually for underwater settlement, construction or maintenance of building structures. It is designed to provide a temporary underwater working platform for construction of construction projects such as bridge foundations, wharves, tunnels, etc. A caisson is usually a large steel or concrete box, which is divided into multiple inner compartments, and the sinking or floating of the caisson is controlled by adjusting the ballast water in the box.

[0003] Nowadays, the production of most caissons adopts the construction method of pouring concrete in layers, that is, a caisson dozens of meters high is constructed in several layers at different time periods, which involves the binding work of steel bars on the inner walls of the standard layers of the caisson at different heights. Currently, after the construction of the caisson base is completed, due to the high standard layer of the caisson, generally, the steel bar cage operation of the standard layer is carried out in layers from bottom to top. During the construction, a binding platform needs to be set up to facilitate the operation personnel to bind the steel bar cage of the standard layer. However, as the standard layer is gradually poured and constructed, the standard layer will gradually increase in height, resulting in the gradual rise of the steel bar cage operation surface, and the height of the conventional binding platform is limited, making it difficult to adapt to the binding of the steel bar cage of the higher standard layer. Summary of the Invention

[0004] The purpose of the present invention is to provide a steel bar binding system for a standard layer of a caisson and a construction method thereof, aiming at the problem in the background art that during the construction of the caisson, as the standard layer is gradually poured and constructed, the steel bar cage operation surface gradually rises, and the height of the conventional binding platform is limited, making it difficult to adapt to the binding of the steel bar cage of the higher standard layer.

[0005] In a first aspect, the present invention provides a steel bar binding system for a standard layer of a caisson, including an outer working platform, an inner working platform, an outer binding platform, an inner binding platform and embedded parts. The embedded parts are arranged on the outer wall of the standard layer of the caisson, and the outer working platform is detachably connected to the embedded parts, and the outer working platform is used to support the outer binding platform;

[0006] The inner working platform is detachably connected to the inner wall of the standard layer of the caisson, and the inner working platform is used to support the inner binding platform;

[0007] The outer binding platform and the inner binding platform are used for binding the steel bar cage.

[0008] For the steel bar binding system described in this application, first, the embedded parts are set on the outer wall of the completed standard layer of the caisson, then the outer working platform is installed on the embedded parts, and then the outer binding platform is supported by the outer working platform, so that the outer binding platform is set on the outer wall of the standard layer of the caisson. Then the inner working platform is installed on the inner wall of the completed standard layer of the caisson, and the inner binding platform is supported by the working platform, so that the inner binding platform is set on the inner wall of the standard layer of the caisson. By supporting the inner and outer binding platforms through the inner and outer working platforms, it is convenient for the operators to bind the steel bar cages of the standard layer at higher positions through the outer binding platform and the inner binding platform, without the need to raise the conventional binding platform, effectively solving the problem that the height of the conventional binding platform is limited and it is difficult to adapt to the binding of steel bar cages of higher standard layers, and greatly improving the construction efficiency of the caisson.

The jib is arranged on one side of the passageway close to the outer wall of the standard layer of the caisson, and one end of the jib is connected to the passageway, and the other end of the jib is detachably connected to the embedded part;

[0010] The passageway is used to support the outer binding platform.

[0011] By setting a jib connected to the passageway, and the jib is detachably connected to the embedded part, the jib is fixedly installed on the embedded part, and then the passageway is fixed on the embedded part through the jib, so as to realize the installation of the passageway on the outer wall of the standard layer of the caisson; further, the outer binding platform is placed on the passageway, and the outer binding platform is supported by the passageway, so that the outer binding platform can be installed on the outer wall of the standard layer of the caisson at a higher position, so that the operators can carry out the binding operation of the steel bar cages of the standard layer at higher positions on the outer binding platform.

[0012] Preferably, one end of the jib close to the embedded part has a strip-shaped groove, and the embedded part is bolted on the strip-shaped groove.

[0013] By setting a strip-shaped groove on the jib and bolting the embedded part on the strip-shaped groove, the jib and the embedded part can be detachably connected, which is convenient for the installation and disassembly of the jib.

[0014] Preferably, the outer working platform further includes a guardrail, and the guardrail is arranged on the side of the passageway away from the outer wall of the standard layer of the caisson.

[0015] Preferably, the embedded parts are arranged at intervals along the circumferential direction of the outer wall of the standard layer of the caisson.

[0018] The plate body is used to support the inner binding platform.

[0019] By arranging a bolt on the plate body, and the bolt extends outwards and is fixed in a reserved groove on the inner wall of the standard caisson layer, it can ensure that the inner working platform 2 is firmly fixed on the inner wall of the standard caisson layer, avoiding displacement or loosening of the platform caused by external forces, thereby improving the stability of the inner working platform 2. At the same time, the design of the bolt makes the installation and disassembly process of the inner working platform 2 more convenient and fast; further, the inner binding platform is supported by the plate body, enabling the inner binding platform to be installed on the inner wall of a relatively high standard caisson layer, facilitating the binding of the steel cage of the standard layer at a higher position.

[0020] Preferably, a receiving cavity is arranged on each side of the plate body, the bolt is movably installed in the receiving cavity, and the bolt can move along the length direction of the receiving cavity, so as to move the bolt in the receiving cavity to make the bolt extend outwards and be installed in the reserved groove on the inner wall of the standard caisson layer.

[0021] Preferably, it further includes a cable, one end of the cable is fixed on the outer binding platform, and the other end of the cable is fixed on the inner binding platform.

[0022] The outer binding platform and the inner binding platform are connected together through the cable to ensure the stability of the outer binding platform and avoid excessive swaying of the outer binding platform, which may affect the operation safety.

[0054] Embodiment 1

[0055] As Figures 1-5 shown, a steel bar binding system for the standard layer of a caisson described in this embodiment includes an outer working platform 1, an inner working platform 2, an outer binding platform 3, an inner binding platform 4, and a pre-embedded part 5. The pre-embedded part 5 is arranged on the outer wall of the standard layer of the caisson. The outer working platform 1 is detachably connected to the pre-embedded part 5, and the outer working platform 1 is used to support the outer binding platform 3;

[0056] The inner working platform 2 is detachably connected to the inner wall of the standard layer of the caisson, and the inner working platform 2 is used to support the inner binding platform 4;

[0057] The outer binding platform 3 and the inner binding platform 4 are used to bind the steel bar cage 50.

[0058] When the steel bar binding system of this embodiment is used, first, the pre-embedded part 5 is set on the outer wall of the completed standard layer of the caisson in advance, then the outer working platform 1 is installed on the pre-embedded part 5, and then the outer binding platform 3 is supported by the outer working platform 1, so that the outer binding platform 3 is arranged on the outer wall of the standard layer of the caisson. Then the inner working platform 2 is installed on the inner wall of the completed standard layer of the caisson, and the inner binding platform 4 is supported by the working platform, so that the inner binding platform 4 is arranged on the inner wall of the standard layer of the caisson. By supporting the inner and outer binding platforms through the inner and outer working platforms, it is convenient for the operators to bind the steel bar cage 50 of the higher standard layer through the outer binding platform 3 and the inner binding platform 4, without the need to raise the conventional binding platform. It effectively solves the problem that the height of the conventional binding platform is limited and it is difficult to adapt to the binding of the steel bar cage 50 of the higher standard layer, and greatly improves the construction efficiency of the caisson.

[0059] In one or several embodiments, as Figure 3As shown, there is a binding area 10 between the outer binding platform 3 and the inner binding platform 4, and between adjacent inner binding platforms 4. The binding operation of the steel cage 50 is carried out in the binding area 10 through the outer binding platform 3 and the inner binding platform 4.

[0060] In one or several embodiments, as Figure 4 , Figure 9 shown, the outer working platform 1 includes an aisle 11 and a jib 12. The jib 12 is arranged on one side of the aisle 11 close to the outer wall of the caisson standard floor, and one end of the jib 12 is connected to the aisle 11, and the other end of the jib 12 is detachably connected to the embedded part 5;

[0061] The aisle 11 is used to support the outer binding platform 3.

[0062] By setting the jib 12 connected to the aisle 11 and detachably connecting the jib 12 to the embedded part 5, the jib 12 is fixedly installed on the embedded part 5, and then the aisle 11 is fixed on the embedded part 5 through the jib 12, so as to realize the installation of the aisle 11 on the outer wall of the caisson standard floor;

[0063] Furthermore, the outer binding platform 3 is placed on the aisle 11, and the outer binding platform 3 is supported by the aisle 11, so that the outer binding platform 3 can be installed on the outer wall of the higher caisson standard floor, so that the operators can carry out the binding operation of the standard floor steel cage 50 on the outer binding platform 3.

[0064] In an alternative embodiment, as Figure 4 , Figure 9 shown, the aisle 11 is assembled by combining multiple steel profiles and channel steels, and its vertical direction includes at least two layers. Among them, the jib 12 is assembled by channel steel or steel profile, one end of which is welded to the aisle 11, and the other end is located above the aisle 11. The jib 12 is used to connect with the embedded part 5.

[0065] In an alternative embodiment, as Figure 10 , Figure 11 shown, one end of the jib 12 close to the embedded part 5 has a strip groove 121, and the embedded part 5 is bolted to the strip groove 121.

[0066] As Figure 4 , Figure 11 shown, the strip groove 121 is arranged along the length direction of the jib 12. When the outer working platform 1 is installed, the arrangement of the strip groove 121 facilitates the jib 12 to be conveniently sleeved on the embedded part 5. Of course, after the jib 12 is installed on the embedded part 5, a nut is sleeved on the embedded part 5, and the nut is tightened to fix the jib 12 on the embedded part 5, so as to fix the outer working platform 1 on the embedded part 5, and then realize the installation of the outer working platform 1 on the outer wall of the caisson standard floor.

[0067] In an alternative embodiment, as Figure 4As shown, the outer working platform 1 further includes a guardrail 13, and the guardrail 13 is arranged on the side of the aisle 11 away from the outer wall of the caisson standard floor.

[0068] By providing the guardrail 13, protection is provided for the operators to ensure their safety.

[0069] In an alternative embodiment, the embedded parts 5 are arranged at intervals along the circumferential direction of the outer wall of the caisson standard floor. By arranging the embedded parts 5 at intervals along the circumferential direction of the outer wall of the caisson standard floor and then installing the outer working platform 1 on the embedded parts 5, the outer working platform 1 is arranged along the circumferential direction of the outer wall of the caisson standard floor, so as to support the outer binding platform 3 at various positions on the outer wall of the caisson standard floor through the outer working platform 1.

[0070] In an alternative embodiment, the embedded part 5 is an embedded screw.

[0071] In one or several embodiments, as Figure 6 shown, the inner working platform 2 includes a plate body 21, and a plug 22 capable of extending outwards is arranged on the plate body 21. The plug 22 is used to be fixed in the reserved groove 20 on the inner wall of the caisson standard floor;

[0072] The plate body 21 is used to support the inner binding platform 4.

[0073] By arranging the plug 22 on the plate body 21 and making the plug 22 extend outwards and be fixed in the reserved groove 20 on the inner wall of the caisson standard floor, it can be ensured that the inner working platform 2 is firmly fixed on the inner wall of the caisson standard floor, avoiding displacement or loosening of the platform caused by external forces, thereby improving the stability of the inner working platform 2. At the same time, the design of the plug 22 makes the installation and disassembly process of the inner working platform 2 simpler and faster; further, by using the plate body 21 to support the inner binding platform 4, the inner binding platform 4 can be installed on the inner wall of the higher caisson standard floor, facilitating the binding of the standard floor steel cage 50 at higher positions.

[0074] In an alternative embodiment, as Figure 7 、 Figure 8 shown, a receiving cavity 23 is arranged on each side of the plate body 21, and the plug 22 is movably installed in the receiving cavity 23, and the plug 22 can move along the length direction of the receiving cavity 23, so as to make the plug 22 extend outwards and be installed in the reserved groove 20 on the inner wall of the caisson standard floor by moving the plug 22 in the receiving cavity 23.

[0075] Further, as Figure 8As shown in the figure, the bolt 22 includes a bolt rod 221 and a pull plate 222 connected to the rod body. A strip-shaped groove 24 is provided at the top of the accommodating cavity 23. The strip-shaped groove 24 is arranged along the length direction of the accommodating cavity 23, and the pull plate 222 is located in the strip-shaped groove 24. During actual construction, when it is necessary to extend the bolt 22, the operator drags the pull plate 222 to move outward. The pull plate 222 drives the bolt rod 221 to move outward from the accommodating cavity 23 to the outside of the plate body 21, realizing the extension of the bolt 22 until the bolt rod 221 enters the reserved groove 20 on the inner wall of the caisson standard floor, completing the installation of the bolt 22 and the reserved groove 20 on the inner wall of the caisson standard floor, fixing the bolt 22 in the reserved groove 20 on the inner wall of the caisson standard floor, and then installing the inner working platform 2 on the inner wall of the caisson standard floor.

[0076] In one or several embodiments, as Figure 1 、 Figure 3 shown, it further includes a cable 30. One end of the cable 30 is fixed to the outer tying platform 3, and the other end of the cable 30 is fixed to the inner tying platform 4.

[0077] The outer tying platform 3 and the inner tying platform 4 are connected together by the cable 30 to ensure the stability of the outer tying platform 3 and prevent excessive shaking of the outer tying platform 3, which may affect the operation safety.

[0078] The cables 30 are arranged at intervals along the height direction of the outer tying platform 3 and the inner tying platform 4. By vertically arranging multiple cables 30 between the outer tying platform 3 and the inner tying platform 4, the connection between the outer tying platform 3 and the inner tying platform 4 is ensured to be firm.

[0079] Adjacent inner tying platforms 4 are connected by cables 30 or chain hoists to ensure that the inner tying platforms 4 form a whole and guarantee their stability.
