Description

The steel reinforcement cage binding and tying by the construction worker lowering to the pit has the following technical problems: (1) there is a hidden danger that the collapse of the foundation pit causes personal injury to the construction worker in the pit; (2) there is a hidden danger that toxic gas in the pit causes personal injury to the construction worker in the pit; and (3) the construction worker needs to climb and bind and tie the steel reinforcement cage, which is inconvenient for operation, resulting in low efficiency and unstable quality of the binding and tying.

[0072] Embodiment 1:

[0073] The traditional method requires construction personnel to bind the reinforcement cage in the pit, which has the hidden danger of pit collapse causing harm to the construction personnel in the pit, and the toxic gas in the pit will cause personal injury to the construction personnel in the pit. In addition, when the construction personnel binds the reinforcement cage in the pit, they need to climb and bind the reinforcement cage, which is not convenient for operation, has low binding efficiency and unstable quality. Based on this, the present embodiment proposes a reinforcement cage binding and lowering integrated device. The device proposed in the present embodiment can bind the reinforcement cage at the pit mouth, and the binding is alternately performed on one section and the lower section, so that the construction personnel do not need to bind the reinforcement cage in the pit, avoiding safety hazards, and efficiently and stably completing the reinforcement cage binding and lowering operation.

[0074] As shown in Figure 1 The device proposed in the present embodiment mainly includes a base 1, a lattice column 2, a lifting ring 3 and a spacing ring 4.

[0075] The base 1 is installed at the pit opening, with its center coinciding with the pit center. The lattice column 2 is vertically installed at the center of the upper plane of the base 1. A lifting device is installed at the top of the lattice column 2. Several spacer rings 4 and a lifting ring 3 are sequentially fitted from bottom to top on the upper plane of the base 1 along the length of the lattice column 2 (i.e., perpendicular to the upper plane of the base), with the lifting ring 3 located at the top. Adjacent spacer rings 4 are connected by steel wire sleeves, and the lifting ring 3 is connected to its adjacent spacer ring 4 by steel wire sleeves. The spacer rings 4 adjacent to the upper plane of the base 1 are fixedly connected to the upper plane of the base 1. The remaining spacer rings 4 and lifting rings 3 can slide along the length of the lattice column 2. Several spacer rings 4 and lifting rings 3 are provided with multiple strip holes at corresponding positions along the circumference for the main reinforcement 6 to pass through. Stirrups 5 are provided outside the main reinforcement 6 and at the upper end inside the base 1. The lifting device at the top of the lattice column 2 is connected to the lifting lugs on the lifting ring 3 through a lifting steel wire rope 7.

[0076] The working principle of the device proposed in this embodiment is as follows: First, the lifting wire rope 7 is tightened by the lifting device at the top of the lattice column 2, thereby lifting the lifting ring 3 upward. When the lifting ring 3 rises, it drives the spacer ring 4 to rise until the main reinforcement 6 reaches the pit opening position. Figure 2 As shown. Then, the main reinforcement bars and stirrups within the base 1 area at the pit opening are tied, as follows. Figure 3 As shown, after the reinforcement is tied, the lifting wire rope 7 is simultaneously released by the lifting device at the top of the lattice column 2, thereby lowering the lifting ring 3. The tied part then enters the foundation pit. The main reinforcement and stirrups within the base 1 area are tied again. After the tying is completed, the lifting wire rope 7 is simultaneously released by the lifting device at the top of the lattice column 2, thereby lowering the lifting ring 3. The tied part then enters the foundation pit. This tying and lowering process is repeated until all the tying is completed and the reinforcement cage is completely placed in the pit. Figure 4 As shown.

[0077] The integrated device proposed in this invention can realize the binding of steel cages at the pit opening, which solves the safety hazards of construction personnel going down into the pit and the problems of low efficiency and unstable process quality in the traditional method of steel cage binding.

[0078] Example 2

[0079] This embodiment further optimizes the base design proposed in the above embodiments, specifically as follows: Figure 5 As shown, the base 1 in this embodiment is mainly composed of an upper ring 8, a lower ring 9, a vertical rod 10, a horizontal rod 15, and a connecting rope 16.

[0080] The upper ring 8 and the lower ring 9 are connected to form a columnar structure by several uprights 10. The outer side of the upper ring 8 is provided with multiple upper connecting ears 13 along the circumference. Correspondingly, the outer side of the lower ring 9 is provided with multiple lower connecting ears 14 along the circumference (i.e., the upper connecting ears 13 and the lower connecting ears 14 are provided one-to-one). These are used to connect the crossbar 15. The upper connecting ears 13 are connected to the free end of the crossbar 15 connected to the corresponding lower connecting ears 14 by connecting ropes 16. The crossbar 15 is provided with counterweights to apply pressure and ensure the stability of the base 1.

[0081] The inner side of the upper ring 8 is connected to the lattice column fixing seat 12 by several connecting rods 11, and the lattice column fixing seat 12 is located at the center of the upper ring 8.

[0082] Specifically, in this embodiment, the upright 10 can be a telescopic adjustable rod to facilitate the adjustment of the height of the base 1.

[0083] Specifically, in this embodiment, the connecting rope 16 is a steel wire rope.

[0084] Example 3:

[0085] This embodiment further optimizes the design of the lattice column 2 proposed in the above embodiment, specifically as follows: Figure 6 As shown, the lattice column 2 is mainly composed of multiple main members 17 and several auxiliary members 18 connected together. For example, the figure shows three main members. The main members can be, but are not limited to, profiles, pipes, etc. The figure shows pipes. It should be noted that the attached figures are for illustrative purposes only and do not limit the materials or quantities.

[0086] The bottom end of the lattice column 2 can be hinged to the lattice column fixing seat 12 on the upper surface of the base 1, so that the lattice column 2 can be rotated and erected as a whole after being hinged to the base 1. After the bottom end of the lattice column is completely attached to the top surface of the lattice column fixing seat, it is then fastened with bolts to fix the lattice column 2 to the lattice column fixing seat 12, thus achieving a reliable connection between the two.

[0087] The lifting device installed at the top of the lattice column 2 includes a winch 19, a pulley 20, a pulley fixing plate 21, and a screw 23.

[0088] The winch 19 can be configured as multiple sets. Specifically, in this embodiment, the winch 19 is configured as 3 sets, and the 3 sets lift simultaneously. The lifting wire rope 7 of each set of winches 19 passes through its corresponding pulley 20 and is vertically connected to the lifting lug 26 of the lifting ring 3. Each pulley 20 is fixed to the outer top of the lattice column 2 by its respective pulley fixing plate 21. Each pulley fixing plate 21 is provided with a screw 23 on the top and outer end to prevent the lifting wire rope 7 from jumping out of the groove.

[0089] The top end of the lattice column 2 is further provided with a pull ear 22. Specifically, the pull ear 22 is evenly arranged along the circumference of the lattice column 2. The pull ear 22 is connected with a steel wire rope, and the free end of the steel wire rope is anchored to the ground in a diagonal manner to ensure the stability of the entire structure (the steel wire rope is not shown in the figure).

[0090] Embodiment 4:

[0091] This embodiment further optimizes the lifting ring 3 proposed in the above embodiments, as shown in Figure 7 and Figure 9 The lifting ring 3 of this embodiment includes a first circular ring 24 and a first sleeve body 25 arranged at the center of the first circular ring 24. The first sleeve body 25 is connected with the first circular ring 24 through a plurality of connecting plates 27. The inner contour of the first sleeve body 25 is sleeved on the lattice column 2 and can smoothly slide on the lattice column 2, which is equivalent to the cooperation between the sliding block and the guide rail. A plurality of lifting lugs 26 are arranged close to the first sleeve body 25. Specifically, three lifting lugs 26 are arranged corresponding to the number of winch sets in this embodiment.

[0092] A plurality of first strip holes 28 are arranged on the first circular ring 24 in a radial direction. The first strip holes 28 can adapt to different diameters of the main reinforcement 6. First guide rails 29 are arranged on both sides of the first strip holes 28. The first guide rails 29 are used to install and fix clamping blocks 30 for the main reinforcement 6. The position of the clamping blocks 30 is adjusted and constrained through the guide rails 29.

[0093] Two clamping blocks 30 provided with grooves are installed on each guide rail 29. Two holes are arranged on each clamping block 30. One of the holes is a threaded hole, and the other is a through hole. The grooves of the two clamping blocks 30 are opposite to each other. The main reinforcement 6 is located in the two grooves, and the clamping of the main reinforcement is achieved through bolt fastening.

[0094] A plurality of connecting rings are evenly arranged on the lower surface of the first circular ring 2 in a circumferential direction, which are used to connect with adjacent spacing rings through steel wire sleeves.

[0095] Embodiment 5:

[0096] This embodiment further optimizes the spacing ring 4 proposed in the above embodiments, as shown in Figure 8 and Figure 9 The spacing ring 4 of this embodiment includes a second circular ring 31 and a second sleeve body 32 arranged at the center of the second circular ring 31. The second sleeve body 32 is connected with the second circular ring 31 through a plurality of connecting pieces 34. The inner contour of the second sleeve body 32 is sleeved on the lattice column 2 and can smoothly slide on the lattice column 2, which is equivalent to the cooperation between the sliding block and the guide rail.

[0097] The second circular ring 31 is provided with a plurality of second strip-shaped holes 35 arranged in the radial direction, and the second strip-shaped holes 35 can adapt to the different diameters of the main reinforcement 6. The second strip-shaped holes 35 are provided with second guide rails 36 on both sides, and the second guide rails 36 are used for mounting the clamping blocks 30 for fixing the main reinforcement 6, and the position of the clamping blocks 30 is adjusted and constrained through the second guide rails 36.

[0098] The uppermost spacer ring 4 and the lifting ring 3, and the adjacent two spacer rings are connected by a plurality of equal-length steel wire sleeves. When the lifting ring 3 is lifted, the main reinforcement 6 that exceeds the plane of the base 1 and is not bound by the stirrup 5 is integrated with the spacer ring 4 under the action of the spacer ring 4, thereby improving the stability of the main reinforcement of the unbound stirrup section.

[0099] In the integrated device according to the embodiment of the application, the lattice column closely cooperates with the lifting ring and the spacer ring, the lattice column plays the role of bearing and guide rail, the lifting and lowering process during the binding of the reinforcement cage is stable, the safety performance is good, and the main reinforcement or the reinforcement cage is prevented from colliding with the pit wall, which is beneficial to the maintenance of the integrity of the pit wall and further improves the operation safety and process quality.

[0100] Embodiment 6:

[0101] The embodiment provides an operation method of the integrated device according to the above embodiment, and specifically includes the following steps.

[0102] Step 1: The pit opening is cleaned and leveled, the base 1 is installed at the pit opening, the center of the base 1 is kept coincident with the center of the pit, and the counterweight is arranged on the horizontal rod 15 of the base 1 to keep the stability of the base 1.

[0103] Step 2: The lattice column 2 is assembled in the horizontal direction, necessary substrates are arranged to keep the horizontal assembly height consistent with the height of the base, the hinge joint between the bottom of the lattice column 2 and the base 1 is connected, the lifting ring 3 and the spacer ring 4 are sleeved on the lattice column 2, the lifting device is installed at the top of the lattice column 2, the pull line is connected to the pull ear 22 at the top of the lattice column 2, and the lattice column is erected by using the method of standing a holding pole. The method of standing a holding pole belongs to the conventional method in the field, and will not be described in detail here. After the lattice column 2 is erected, the lattice column 2 is connected and fixed to the base 1 firmly, the pull line is led to the ground anchoring point obliquely downward, and is tightened and adjusted to keep the lattice column 2 in the vertical state and fixed firmly.

[0104] Step 3: The lifting device is debugged in the empty state, so that the three groups of winches 19 at the top of the lattice column 2 synchronously lift the lifting ring, the lifting steel wire ropes of the three groups of winches are uniformly stressed, and the lifting process is smooth and smooth.

[0105] Step 4, the main reinforcement 6 which has been put into the foundation pit is lifted and installed on the lifting ring 3, the head of the main reinforcement 6 penetrates through the spacer ring 4 and the strip-shaped hole of the lifting ring 3, and the clamping block 30 on the lifting ring 3 clamps the main reinforcement 6, and the exposed length of each main reinforcement 6 on the lifting ring 3 is consistent. The main reinforcement 6 should be symmetrically installed on the lifting ring 3 in cross, so as to keep the force of the lifting ring 3 balanced and avoid being installed from one position to another.

[0106] Step 5, after the installation of all the main reinforcement 6 on the lifting ring 3 is completed, the winch 19 is started to slowly lift the lifting ring 3, and the lifting is paused when the steel wire sleeve between the first spacer ring 4 connected below the lifting ring 3 is stressed, the clamping block 30 on the spacer ring 4 clamps the main reinforcement 6, and then the lifting is continued, and the lifting is paused again when the steel wire sleeve between the next spacer ring 4 connected below is stressed, and the clamping block clamps the main reinforcement, and then the lifting is continued.

[0107] Step 6, when the lower end of the main reinforcement 6 is lifted to the position of the pit opening, the main reinforcement 6 and the stirrup 5 in the range of the base 1 can be bound, and after the binding is completed, the winch 19 at the top of the lattice column is loosened to lower the lifting wire rope, and the bound part enters the pit.

[0108] Step 7, the main reinforcement and the stirrup in the range of the base are bound again, and after the binding is completed, the winch at the top of the lattice column is loosened to lower the lifting wire rope, and the bound part enters the pit, and the binding and lowering process are repeated in turn until the binding is completed and the whole reinforcement cage is completely put into the pit. During the lowering process, the clamping block on the corresponding spacer ring or lifting ring needs to be loosened.

[0116] Step 3: lift and install the main reinforcement 6 in the foundation pit on the lifting ring 3 one by one, the head of the main reinforcement 6 passes through the strip-shaped hole of the spacing ring 4 and the lifting ring 3, the clamping block 30 on the lifting ring 3 clamps the main reinforcement 6, and the exposed length of each main reinforcement 6 on the lifting ring 3 is kept consistent. The main reinforcement 6 should be symmetrically installed on the lifting ring 3 one by one to keep the force balance of the lifting ring 3 and avoid installation from one position.

[0117] Step 4: after all the main reinforcements 6 are installed on the lifting ring 3, start the winch 19 to slowly lift the lifting ring 3, pause the lifting when the steel wire sleeve between the first spacing ring 4 connected below the lifting ring 3 is stressed, clamp the main reinforcement 6 at this position by the clamping block 30 on the spacing ring 4, then continue lifting, and then pause the lifting when the steel wire sleeve between the next spacing ring 4 is stressed, and then continue lifting after clamping the main reinforcement by the clamping block.

[0118] ​Step 5, when the lower end of the main reinforcement 6 is lifted to the pit opening position, the main reinforcement 6 and the stirrup 5 are tied at the pit opening, and after the tying is completed, the hoist 19 at the top of the lattice column is loosened to lower the lifting wire rope and the lifting ring, and the tied part enters the pit.

[0119] Step 6, then the main reinforcement and the stirrup are tied again at the pit opening position, and after the tying is completed, the hoist at the top of the lattice column is loosened to lower the lifting wire rope and the lifting ring, and the tied part enters the pit, and the tying and lowering process are repeated in sequence until all the tying is completed and all the reinforcement cages are completely placed in the pit. Similarly, the clamping blocks on the corresponding spacing rings or lifting rings also need to be loosened in sequence during the lowering process, and the specific process is as described in the above embodiment 6, which will not be repeated here.
