Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a vertical combination mold for tower crane counterweights and its construction method. Background Technology

[0002] Tower cranes are important pieces of machinery for vertical transportation in construction, and the counterweights on the tower crane's counterweight boom are like... Figure 1 The large counterweight 3 and small counterweight 4 shown range in weight from 15t to 30t per tower crane. Generally, there are multiple large counterweights and one to two small counterweights. They are used to balance the forward tilting moment of the tower crane's jib. The number of counterweights corresponds to the combined length of the jib; the longer the jib, the more counterweights are needed for balance. Since the counterweights are suspended in the air and rotate with the counterweight boom 2, any quality issues such as insecure suspension, breakage, or deformation could cause them to fall from a height, potentially leading to tower crane overturning. Therefore, the manufacturing quality of the counterweights determines the tower crane's performance and operational reliability, thus affecting construction efficiency and safety.

[0003] The counterweight of a tower crane is a combination of multiple rectangular reinforced concrete blocks of varying lengths. The traditional method of construction is to lay them in a row on an open outdoor ground, such as... Figure 2 As shown, multiple rectangular frames are formed using large counterweight block template 5 and small counterweight block template 6. Large counterweight block steel reinforcement frames 31 and small counterweight block steel reinforcement frames 41 are placed within these frames before concrete is poured. Existing flat-laying pouring methods suffer from drawbacks such as large footprint, complex process flow, low manufacturing efficiency, sensitivity to weather conditions, easy template displacement and deformation leading to large dimensional deviations in the counterweight blocks, large upper surface area during pouring making manual smoothing difficult to guarantee flatness, poor sealing at the large counterweight block lifting lugs 32 and 42 on the sides resulting in grout leakage and environmental pollution, low turnover rate of template materials, and significant waste.

[0055] The following is for reference. Figures 1 to 8 The vertical assembly mold for tower crane counterweights according to an embodiment of this application is described in detail with reference to a specific example. It is to be understood that the following description is merely illustrative and not intended to limit the invention.

[0056] like Figure 3 and Figure 4 As shown, the tower crane counterweight vertical combination mold includes a base 7, a fixed template 71 fixedly connected to one side of the base 7, and multiple first vertical molds 8. In this embodiment, the first vertical mold 8 is a standard counterweight mold.

[0057] The second vertical mold 9, in this embodiment, is an electric counterweight mold. The fixed template 71, multiple first vertical molds 8 and the second vertical mold 9 are sequentially and movably arranged on the base 7.

[0058] like Figure 6 As shown, the base 7 includes a track 74. In this embodiment, two tracks 74 are provided, consisting of two parallel circular guide rails, serving as guide rails for mold movement. A fixed template 71 is provided at one end of the track 74, and a baffle 76 is provided at the other end to prevent the mold from detaching from the track 74. The track 74 is connected by multiple supports 75 to form a steel frame. Multiple support legs 78 are evenly arranged under the steel frame to ensure that the overall steel frame is in stable contact with the ground. A rack 77 is installed in the middle of the track 74. The fixed template 71 is at a 90° angle to the track 74 and is firmly welded to the track 74 as a fixed vertical template.

[0059] like Figure 7The diagram shows the structure of the first vertical mold 8. The first vertical mold 8 includes a first base plate 88, a first vertical plate 81, and two opposing and spaced-apart first side plates 83. The two first side plates 83 are connected to the first vertical plate 81. The first base plate 88, the first vertical plate 81, and the two first side plates 83 together form a first opening 801.

[0060] Four rollers 89 are installed under the first base plate 88. The rollers 89 travel on two tracks 74 of the base 7, supporting the weight of the entire upper mold and preventing the box from tipping over. Two first supports 85 are welded and fixed to the bottom sides of the first base plate 88. A first rocker arm 84 is installed on the first support 85. A first gear 87 is installed in the middle of the rocker arm. The first gear 87 meshes with the rack 77 on the base 7. Rotating the first rocker arm 84 can move the first vertical mold 8.

[0061] The first opening 801 is provided with a U-shaped groove, and a first sealing element 82 is provided in the U-shaped groove. In this embodiment, the first sealing element 82 is a silicone waterstop strip or a rubber waterstop strip to ensure the sealing effect.

[0062] like Figure 5 As shown, the locking device includes a first connecting seat 72, a second connecting seat 813, a bolt 810, and a nut 811. The second connecting seat 813 is hinged to one side of the bolt 810, and the other side of the bolt 810 is screwed to the nut 811. In this embodiment, both the first connecting seat 72 and the second connecting seat 813 are concave. Further, the second connecting seat 813 is a concave connecting support with a hole. In this embodiment, the bolt 810 is an eye bolt.

[0063] Specifically, four sets of first connecting seats 72 and second connecting seats 813 are symmetrically arranged on the left and right sides of the first vertical mold 8 in two rows. The second connecting seat 813 is hinged to the bolt 810 through the pin 812. The bolt 810 rotates around the pin 812 as the axis. The bolt 810 is rotated to the middle of the groove of the first connecting seat 72 which is concave in front. The nut 811 is screwed in along the thread of the bolt 810 to tighten it, so as to achieve a tight connection between the front and rear molds.

[0064] like Figure 6 As shown, four sets of first connecting seats 72 are symmetrically arranged in two rows on the left and right sides of the fixed template 71. The second connecting seat 813, bolt 810 and nut 811 are fixedly connected to the adjacent first vertical mold 8 at the corresponding positions to realize the locking connection between the fixed template 71 and the first vertical mold 8.

[0065] like Figure 8As shown, the second vertical mold 9 is 1 / 3 to 1 / 2 shorter than the first vertical mold 8. The second vertical mold 9 is divided into upper and lower frames. Specifically, the second vertical mold 9 includes a second base plate 96, a third base plate 95, a second vertical plate 91, and two opposing and spaced second side plates 803. The two second side plates 803 are connected to the second vertical plate 91. The second base plate 96, the second vertical plate 91, and the two second side plates 803 together form a second opening 802. The two sides of the third base plate 95 are fixedly connected to the lower ends of the two second side plates 803 respectively. The second base plate 96 is located above the third base plate 95. The second base plate 96 divides the second vertical mold 9 into a third casting cavity 530 located in the upper part and an installation cavity located in the lower part. The electric device is located in the installation cavity, and an inspection port for inspecting the electric device is provided on one side of the installation cavity.

[0066] The electric actuator includes a motor 92, a gearbox 93, and a third gear 94 installed at the output end of the electric actuator. Two second supports 805 are welded and fixed to both sides of the bottom of the third base plate 95. A second rocker arm 804 is mounted on each second support 805, and a second gear 807 is mounted on each second rocker arm 804. The second gear 807 meshes with a rack 77 on the base 7, enabling electric movement of the second vertical mold 9. The second rocker arm 804 can also be used to manually move the second vertical mold 9. Four rollers 89 are installed under the third base plate 95. The rollers 89 travel on two tracks 74 on the base 7, supporting the weight of the entire upper mold and preventing the box from tipping over.

[0067] The second opening 802 is provided with a U-shaped groove, and a second sealing element 97 is provided in the U-shaped groove. In this embodiment, the second sealing element 97 is a silicone waterstop strip or a rubber waterstop strip to ensure the sealing effect.

[0068] like Figure 8 As shown, four sets of second connecting seats 813 are symmetrically arranged in two rows on the left and right sides of the second vertical mold 9. The second connecting seats 813 are hinged to bolts 810 through pins 812. The bolts 810 rotate about the pins 812 as the axis. The bolts 810 are rotated to the middle of the groove of the concave first connecting seat 72 provided on the first vertical mold 8 adjacent to the second vertical mold 9. The nuts 811 are screwed in along the threads of the bolts 810 to tighten them, so as to achieve a tight connection between the front and rear molds.

[0069] like Figure 3 and Figure 4 as well as Figure 9 and Figure 10As shown, the tower crane counterweight vertical combination mold has an assembled state and a disassembled state. In the assembled state, the fixed template 71 is closed by the locking device 10 to the first opening 801 of the adjacent first vertical mold 8 to form a first casting cavity 510. The upper end of the first casting cavity 510 has a first casting port. The two adjacent first vertical molds 8 are closed by the locking device 10 to the first opening 801 of one first vertical mold 8 and the first vertical plate 81 of the other first vertical mold 8 to form a second casting cavity 520. The upper end of the second casting cavity 520 has a second casting port. The second opening 802 is closed by the locking device 10 to the first vertical plate 81 of the adjacent first vertical mold 8 to form a third casting cavity 530. The upper end of the third casting cavity 530 has a third casting port.

[0070] like Figure 3 As shown, after the vertical combination mold of the tower crane counterweight block is assembled, a release agent is applied to each casting cavity. The first steel frame 311 is vertically placed into the first casting cavity 510 and the second casting cavity 520 using a crane, and the second steel frame 411 is vertically placed into the third casting cavity 530. The first steel frame 311 includes a first lifting lug facing upwards, and the second steel frame 411 includes a second lifting lug facing upwards.

[0071] Then, pour concrete from top to bottom through the first pouring gate, the second pouring gate, and the third pouring gate, and finally scrape the surface concrete smooth.

[0072] After the concrete has dried, first release the locking device 10 between the second vertical mold 9 and the adjacent first vertical mold 8, start the electric device to separate the second vertical mold 9, and use the second lifting lug to lift out the second counterweight block 421 formed by the second vertical mold 9.

[0073] The electric device is activated to reconnect and lock the second vertical mold 9 and its adjacent first vertical mold 8 through the locking device 10 to form the first finished component 111. The locking device 10 on one side of the first finished component 111 is released, and the electric device is activated to separate the first vertical mold 8 adjacent to the second vertical mold 9. The first counterweight 321 formed by the first vertical mold 8 is lifted out by the first lifting lug. Then the electric device is activated again to reconnect and lock it to form the second finished component 112.

[0074] Repeat the above steps, pointing from the second vertical mold 9 to the fixed template 71, and lift out the remaining first counterweights 321 formed by the first vertical mold 8 one by one.

[0075] In this embodiment, after the concrete pouring is completed and the pre-drying period is reached, the counterweight can be demolded. During demolding, the four sets of bolts 810 and nuts 811 between the second vertical mold 9 and its adjacent first vertical mold 8 are loosened until the bolts 810 can be rotated to loosen the connection between the molds. The second vertical mold 9 is then moved to the right to separate it from its adjacent first vertical mold 8 and move a certain distance. The second lifting lug is used to lift the second counterweight 421 away from the second vertical mold 9. The second vertical mold 9 is then moved to the left to reconnect it with the adjacent first vertical mold 8. At the same time, the four sets of connecting bolts 810 and nuts 811 connected to the left side of the first vertical mold 8 are loosened. The second vertical mold 9 is then moved to the right to move the first vertical mold 8 to the right. After the first counterweight 321 is loosened, the first lifting lug is used to lift the first counterweight 321 away from the mold cavity of the first vertical mold 8. By repeating the above actions, the remaining first counterweights 321 can be vertically lifted out of the cavity of the first vertical mold 8 one by one.

[0076] The vertical combination mold for tower crane counterweights in this application creates a new mold for each counterweight block demolded, preparing for the next batch of concrete pouring and improving construction efficiency.

[0077] The number of standard counterweight blocks and electric counterweight block molds in this vertical combination mold is based on the requirements of each tower crane in one batch. When the batch size increases or the tower crane model changes, the number of combinations can be adjusted accordingly. It has a creative application for standardized, large-scale, and industrialized production.

[0078] Using one tower crane counterweight as a batch, standard first vertical molds 8 are arranged in close succession, with the last row being standard electric second vertical molds 9. The vertical combination mold structure is reasonable and compact. Compared with traditional flat formwork, it has the advantages of small footprint, high mold turnover rate, no consumables manufacturing, all outer surfaces are formed in one step after pouring without secondary finishing, the surface of the counterweight is smooth after demolding, and the quality is guaranteed. The upper end face of the mold is flat, the counterweight lifting lug is at the top, and the concrete on the upper end face is scraped or self-flowed, without the need for sealing the mold. At the same time, the counterweight can be directly lifted and separated by the lifting lug during demolding, resulting in high production efficiency. It can be produced in the factory workshop and is suitable for mass production and large-scale manufacturing.
