Description

Technical Field

[0001] The utility model mainly relates to the technical field of steel bar construction, and particularly relates to a longitudinal steel bar storage mechanism suitable for the construction of the secondary lining of a tunnel. Background Art

[0002] Secondary lining (referred to as "second lining" for short) is a commonly used term in tunnel engineering construction. It refers to the reinforced concrete lining constructed on the inner side of the primary support, aiming to jointly form a composite lining with the primary support to achieve the effect of strengthening the support and thus meet the requirements of modern tunnel construction.

[0003] The secondary lining includes steel bar construction, that is, an arched steel bar cage adapted to the shape of the tunnel inner wall is formed by tying. When using tunnel steel bar cage operation equipment (such as the technical solution disclosed in the Chinese patent application document with the application publication number: CN 115163139 A and the invention name "Tunnel Steel Bar Cage Operation Equipment and Tunnel Steel Bar Cage Construction Method") for steel bar construction, it is necessary to set up a storage mechanism to carry longitudinal steel bars and move along the tunnel circumferential direction with the steel bar pulling device. The lengths of the longitudinal steel bars are different, and the storage spaces of the existing longitudinal steel bar storage mechanisms are arranged linearly, which results in either storing longitudinal steel bars of different lengths in a mixed manner or storing steel bars of different lengths in the storage mechanism in sequence according to the preset use order. However, no matter which method is used, the workload will be increased, thus affecting the construction progress. Therefore, a longitudinal steel bar storage mechanism that is convenient for partition management is needed. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a longitudinal steel bar storage mechanism suitable for the construction of the secondary lining of a tunnel.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A longitudinal steel bar storage mechanism suitable for the construction of the secondary lining of a tunnel includes at least three cross beams arranged at intervals in the vertical direction. Each of the cross beams is connected to the same vertical column, thereby forming at least two layers of transverse storage spaces with one end open. The transverse storage spaces are divided into several partition spaces by a number of partition members detachably connected to the cross beams.

[0007] As a further improvement of the above technical solution:

[0008] A number of bayonet openings for fixing the partition members are formed on the surface of the cross beam facing the adjacent cross beam, and the bayonet openings are arranged at intervals along the length direction of the cross beam.

[0009] The bayonet openings are arranged in a groove-like structure, and the plate-shaped partition members can be detachably and slidably inserted therein.

[0010] The blocking member is configured as a pin rod which penetrates each cross beam in a pluggable manner in the vertical direction.

[0011] The storage mechanism also includes a blocking rod, one end of which is connected to the end of the beam away from the column, and the other end of which forms a gap for the longitudinal steel bars to move out with the adjacent beam and the adjacent blocking rod above.

[0012] The blocking rod and the crossbeam are arranged to be detachably connected.

[0013] The blocking rod is connected with the crossbeam via a quick-release latch.

[0014] The storage mechanism also includes a reinforcing plate attached to the side surfaces of the cross beam and the column, and the reinforcing plate covers the joint between the cross beam and the column.

[0015] There are two reinforcing plates, which are symmetrically attached to both sides of the crossbeam and the column.

[0016] The storage mechanism also includes a connecting plate, which is attached to the bottom surface of the beam located at the bottom, and has a plurality of connecting holes formed on the connecting plate.

[0017] Compared with the prior art, the advantages of the utility model are:

[0018] By setting up multi-layer partition spaces, longitudinal steel bars of different lengths can be concentrated in the partition space of the same layer, so that operators can selectively release the required length of longitudinal steel bars according to actual needs, thus having a more flexible operating space. At the same time, it can reduce the workload of operators in distinguishing the required length of longitudinal steel bars from the mixed steel bar pile, and can also speed up the construction progress accordingly.

Specific implementation mode

[0025] The following will further elaborate on the present utility model in conjunction with the specification drawings and specific embodiments.

[0026] Embodiment 1

[0027] As Figure 1 and Figure 2As shown in the figure, the longitudinal steel bar storage mechanism applicable to the secondary lining construction of tunnels in this embodiment includes three cross beams 1 arranged at intervals vertically. The right ends of the three cross beams 1 are all connected to the columns 2, thereby forming two layers of horizontally arranged storage spaces 3 with open left ends. Each layer of the horizontally arranged storage space 3 is divided into five partition spaces 5 by four partition members 4 detachably connected to the cross beam 1. In each partition space 5 on the upper layer, there are A1 longitudinal steel bars with a length of B1 stored, and in each partition space 5 on the lower layer, there are A2 longitudinal steel bars with a length of B2 stored (the storage method of the longitudinal steel bars is the same as that in the prior art). The storage mechanism is connected to an external steel bar pulling device and moves along the tunnel circumferential direction following the external steel bar pulling device. Whenever the storage mechanism moves a certain distance along the tunnel circumferential direction, a certain number of longitudinal steel bars need to be taken out from the storage mechanism for binding. If at this time, A1 longitudinal steel bars with a length of B1 need to be bound, the operator only needs to remove one partition member 4 installed in the upper horizontally arranged storage space 3 to release the longitudinal steel bars that meet the requirements. If at this time, A2 longitudinal steel bars with a length of B2 need to be bound, the operator only needs to remove one partition member 4 installed in the lower horizontally arranged storage space 3 to release the longitudinal steel bars that meet the requirements. In the prior art, the storage space for placing longitudinal steel bars has only one layer and is arranged in a straight line. If the longitudinal steel bars placed in the three storage spaces arranged in sequence from the outside to the inside are: A1 longitudinal steel bars with a length of B1, A2 longitudinal steel bars with a length of B2, and A1 longitudinal steel bars with a length of B1 respectively, then, if after binding A1 longitudinal steel bars with a length of B1, another A1 longitudinal steel bars with a length of B1 need to be bound, it is necessary to first release the A2 longitudinal steel bars with a length of B2. This will cause the released A2 longitudinal steel bars with a length of B2 to be mixed with the released A1 longitudinal steel bars with a length of B1, thus possibly resulting in the incorrect mixing of longitudinal steel bars of different lengths. When using the storage mechanism disclosed in this application to store longitudinal steel bars, the operator can selectively release the longitudinal steel bars of the required length according to actual needs. Therefore, there is a more flexible operation space, and at the same time, the workload of the operator to distinguish the longitudinal steel bars of the required length from the mixed steel bar pile can be reduced, and the construction progress can also be accelerated accordingly.

[0028] In this embodiment, four clamping openings 11 for fixing the partition member 4 are formed on one side of the cross beam 1 facing the adjacent cross beam 1, and the clamping openings 11 are arranged at intervals along the length direction of the cross beam 1. The clamping openings 11 are arranged in a groove-like structure, and the plate-shaped partition member 4 can be detachably and slidably inserted therein. When the operator needs to release the longitudinal steel bars in the partition space 5, only need to pull out the partition member 4 along the length direction of the groove-like clamping opening 11. This structure form of the groove and the plate is simple, reliable, and easy to manufacture. Of course, in other embodiments, the clamping openings 11 and the partition member 4 can also be set in different structural forms, which are not limited here.

[0029] In this embodiment, the storage mechanism further includes a blocking rod 6, one end of which is connected to the end of the beam 1 away from the column 2, and the other end of which is connected to the adjacent beam 1 located above and the adjacent blocking rod 6 located above to form a gap for the longitudinal steel bars to move out. The blocking rod 6 is hook-shaped, and is detachably connected to the beam 1 via a quick-release pin 7. By providing the blocking rod 6, it is possible to prevent the longitudinal steel bars released due to the blocking member 4 being pulled out from slipping out of the storage mechanism. Since one end of the blocking rod 6 is connected to the adjacent beam 1 located above and the adjacent blocking rod 6 located above to form a gap for the longitudinal steel bars to move out, the operator can sequentially move the longitudinal steel bars out of the gap according to the binding progress, thereby improving the safety performance of the storage mechanism.

[0030] In this embodiment, the storage mechanism further includes two reinforcing plates 8 symmetrically attached to the sides of the cross beam 1 and the upright column 2. The reinforcing plates 8 are in an "E" shape, covering the joint between the cross beam 1 and the upright column 2 while avoiding the horizontal storage space 3. By providing the reinforcing plates 8, the connection stability between the cross beam 1 and the upright column 2 can be enhanced, thereby optimizing the force and reducing the structural deformation.

[0031] In this embodiment, the storage mechanism further includes a connecting plate 9, which is attached to the bottom surface of the lowest crossbeam 1, and has a plurality of connecting holes 91 formed on the connecting plate 9. The other side of the connecting plate 9 is connected to a mounting seat formed on the external steel bar pulling device, and the two are firmly connected via bolts passing through the connecting holes 91.

[0032] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are relative concepts for the convenience of understanding. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation and direction of operation. Therefore, they cannot be understood as limitations on the present invention.

[0033] Example 2

[0034] like Figure 3 As shown, the longitudinal steel bar storage mechanism for tunnel secondary lining construction of this embodiment is basically the same as that of the embodiment 1, and the difference is only that: the blocking member 4 is set as a pin rod, which can be inserted and pulled through each beam 1 in the vertical direction. Each beam 1 is formed with 4 vertical through holes 12, and the through holes 12 formed on each beam 1 correspond vertically. When the pin rod vertically penetrates the through holes 12 on each beam 1, each layer of the horizontal storage space 3 is divided into five partition spaces 5, and each partition space 5 can store longitudinal steel bars. When the longitudinal steel bars need to be taken out, only the pin rod needs to be pulled out.

The blocking member 4 divides each layer of the horizontal storage space 3 into five partition spaces 5, and longitudinal steel bars can be stored in each partition space 5. When it is necessary to take out the longitudinal steel bars, only the pin 10 needs to be pulled out and the blocking member 4 removed.

[0037] Embodiment 4

[0038] As Figure 5 shown in the figure, the longitudinal steel bar storage mechanism applicable to the secondary lining construction of tunnels in this embodiment is basically the same as that in Embodiment 1, and the difference is only that: at least two cross beams 1 are provided with 4 slots 14 at intervals along the length direction of their own sides, and the plate-shaped blocking member 4 is inserted into the slots 14, and the blocking member 4 and the slots 14 are connected by a pin 10. The blocking member 4 divides each layer of the horizontal storage space 3 into five partition spaces 5, and longitudinal steel bars can be stored in each partition space 5. When it is necessary to take out the longitudinal steel bars, only the pin 10 needs to be pulled out and the blocking member 4 removed.
