Description

Technical Field

[0001] The invention belongs to the technical field of precast concrete slab production, and in particular relates to an integrated mobile device for producing precast concrete slabs and a production process. Background Art

[0002] Vigorously developing prefabricated buildings has become the basic direction of my country's construction industry upgrade. The use of prefabricated concrete components, especially floor slabs and wall panels, is increasing. Traditional production processes and methods not only require large investments, low efficiency, and high energy consumption, but also have production capacity that is increasingly unable to meet market demand.

[0003] In layman's terms, prefabricated construction means building a house like building a car, that is, the house is disassembled into various components (such as beams, panels, columns, etc.) and processed and produced in the factory, and then transported to the construction site for on-site assembly. Among them, the most widely used are prefabricated concrete panels, including floor panels, wall panels, air conditioning panels, etc.

[0004] The necessary process is: formwork in place → assemble the mold → place the steel bars and embedded parts → pour concrete → component curing (steam can be used) → component demoulding → hoisting and shipment. The existing production processes of precast concrete components include fixed formwork flat production and flat mold assembly line production.

[0005] Fixed mold platform flat production: Figure 1 As shown, the formwork is laid flat in the workshop and fixed in place. After the formwork is assembled and poured, the single-layer plane is maintained, which consumes a lot of energy. The finished products are hoisted in situ one by one, which occupies a large area, has a large basic investment, low production efficiency, and requires a lot of personnel.

[0006] Flat mold production line: Figure 2 As shown, the mold table is placed on the track, the production station personnel do not move, the mold table moves on the track, and is lifted to the centralized point for maintenance through extremely complex mechanical devices. This method requires high requirements for factory buildings and infrastructure, large investments, and long construction periods; high investment in production equipment and long installation periods; complex electronic control equipment and high requirements for operators; large production area; products produced at different times are maintained in the same maintenance area, which not only consumes a lot of energy, but also makes it difficult to ensure product quality; the mold table can only move in a plane and can only move along the specified route, failing to make reasonable use of space and resulting in low production efficiency. For single-line assembly line operations, once any link has a problem, the entire production line will be blocked; material organization and finished product transportation routes are too long, inefficient, and wasteful; and cross-operation is not allowed.

[0007] Therefore, the defects of the existing precast concrete component production method are: fixed plant plus permanent facilities, huge capital construction investment, long construction period, difficult relocation, transportation restrictions, inability to carry out long-distance projects and environmental pollution.

[0073] Specifically, the formwork body 101 is a plate structure, the upper surface is required to be flat, and it is used as a base for the precast concrete components, and the lower surface is placed on the formwork base or the formwork support column 102. The thickness of the formwork depends on the spacing between the formwork support columns 102: the larger the spacing between the formwork support columns 102, the greater the thickness of the formwork, so as to ensure its plane rigidity requirements.

[0074] like Figure 10-11 As shown, the mold base 6 includes a mold base body 601 and mold base lifting rings 602 arranged on both sides of the mold base body 601. The walking gantry 2 is connected to the mold base lifting rings 602 on both sides of the mold base body 601 through the gantry sling 4 to realize the lifting of the mold base 6.

[0075] The mold base 6 is the base for stacking the mold base 1, and its plane size is the same as that of the mold base 1. The mold base body 601 is a high-strength, high-rigidity platform frame, on which the multi-layer mold base 1 is stacked. The mold base 6 not only bears the weight, but also ensures the stability of the upper multi-layer mold base 1. The mold base lifting ring 602 is firmly fixed to the side of the mold base body 601, and the demoulding lifting tool 7 lifts the mold base 6 and the upper load through the mold base lifting ring 602.

[0076] like Figure 12-13As shown, the mold platform hanger 3 includes a mold platform hanger 301, a clamp 302, a guide plate 303 and a mold platform lifting ring 304, wherein the top of the mold platform hanger 301 is provided with a mold platform lifting ring 304 for connecting with the gantry sling 4; the bottom of the mold platform hanger 301 is provided with a plurality of clamps 302 for clamping the mold platform support column 102; and the four corners of the mold platform hanger 301 are provided with guide plates 303 for positioning the mold platform 1.

[0077] like Figure 14-17 As shown, the clamp 302 includes a guide rod 3021, a spring 3022, a telescopic guide sleeve 3023, a chuck 3024, a clamping guide sleeve 3025, a clamping pin 3026 and a clamping drive mechanism, wherein the telescopic guide sleeve 3023 is arranged on the die table hanger 301, the guide rod 3021 is slidably inserted in the telescopic guide sleeve 3023, the upper and lower ends of the guide rod 3021 are respectively connected to the limit block and the chuck 3024, the spring 3022 is sleeved on the outer side of the telescopic guide sleeve 3023, and the two ends are respectively abutted against the limit blocks on the upper end of the telescopic guide sleeve 3023 and the guide rod 3021. When the chuck 3024 contacts the die table support column 102, the spring 3022 plays a buffering role.

[0078] In an embodiment of the present invention, two clamping guide sleeves 3025 are radially provided on the side wall of the chuck 3024, and a clamping pin 3026 is slidably fitted in the two clamping guide sleeves 3025 respectively, and the outer end of the clamping pin 3026 is connected to the clamping drive mechanism; the clamping drive mechanism drives the clamping pin 3026 to retract and retract, thereby realizing the clamping and release of the mold table support column 102.

[0079] When the clamping drive mechanism drives the two clamping pins 3026 to extend, they enter the annular groove 1021 on the die table support column 102 to clamp the die table support column 102. The clamping drive mechanism can be driven by a hydraulic cylinder.

[0080] Furthermore, the clamp 3024 is a hollow structure, and the opening at the lower end is trumpet-shaped, which is convenient for positioning and connecting with the mold platform support column 102.

[0081] The die table hanger 301 is a flat rigid frame to ensure that each hanging point is stressed synchronously and maintains balance and stability. The clamp 302 is fixed to the lower part of the die table hanger 301, and the position and number are the same as the die table support column 102. The groove of the clamp 3024 is connected to the top of the die table support column 102 for locking and lifting.

[0082] The guide plate 303 is fixed to the four corners of the mold platform hanger 301. By aligning the guide plate 303 with the mold platform base or the four corners of the mold platform 1 to ensure that the upper and lower four corners are flush, the internal clamp 302 can be accurately connected with the mold platform support column 102.

[0083] like Fig.18As shown, the concrete placing machine 5 is used for pouring concrete, and includes a hopper track 501, a fixed beam 502 and a hopper 503, wherein the hopper track 501 is provided at the bottom of the fixed beam 502, the hopper 503 is connected to the hopper track 501 through a translation wheel 504, and the top of the fixed beam 502 is provided with a connecting ring 505 for connecting to the gantry sling 4. The hopper 503 moves on the hopper track 501 through the translation wheel 504 to adjust the position of the hopper 503.

[0084] Specifically, the hopper track 501 can be a single-beam or double-beam track, and the upper part is connected to the top steel frame of the gantry through the connecting ring 505, and the height can be adjusted up and down; the hopper 503 is suspended at the lower part. The fixed beam 502 is fixed to the support on the side of the gantry to ensure the stability of the hopper track 501 and prevent it from shaking laterally. The hopper 503 is used to store concrete, and there is a switch distribution device at the bottom. The upper part of the translation wheel 504 is connected to the hopper track 501, and the lower part is connected to the hopper 503, so that the hopper 503 can slide along the hopper track 501 to ensure the accurate distribution position. The connecting ring 505 connects the hopper track 501 and the bottom steel frame of the gantry to maintain stability.

[0085] like Figure 19-20 As shown, the demoulding hanger 7 lifts the precast concrete slab 8, i.e., the finished product is hoisted. The demoulding hanger 7 comprises a demoulding hanger 701, a pulley block 702 and a demoulding lifting ring 703, wherein the top of the demoulding hanger 701 is provided with a demoulding lifting ring 703 for connecting with the gantry sling 4; the bottom of the demoulding hanger 701 is provided with a pulley block 702.

[0086] like Fig.19 As shown, the pulley block 702 includes a steel wire rope 7022, a plurality of fixed pulleys 7021 and a plurality of movable pulleys 7023, wherein the plurality of fixed pulleys 7021 are arranged at intervals on the demoulding hanger 701; one end of the steel wire rope 7022 is connected to the fixed pulley 7021 located at one end, and the other end of the steel wire rope 7022 is alternately connected to the movable pulley 7023 and the fixed pulley 7021 in sequence and the end is connected to the fixed pulley 7021 located at the other end; each movable pulley 7023 is provided with a hook 7024, forming a pulley block hanger with uniform force.

[0087] Specifically, the demoulding hanger 701 is a U-shaped or J-shaped welded steel frame.

[0088] A production process for mobile production of precast concrete panels, comprising the above-mentioned integrated device for mobile production of precast concrete panels, the production process comprising the following steps:

[0089] 1) Workstation layout: Fig. 27 As shown, a base station and a plurality of die table stations are arranged along the walking route of the walking gantry 2;

[0090] In this embodiment, six mold table stations and one base station are arranged.

[0091] 2) Die table layout: Figure 3 As shown, the die table hoist 3 is connected to the gantry sling 4 of the traveling gantry 2, and the die table 1 is hoisted to each die table station through the die table hoist 3;

[0092] Specifically, the gantry sling 4 is drooped, and the guide plate 303 of the formwork platform hanger 3 is first aligned with the four corners of the formwork platform 1; the clamp 302 at the bottom of the formwork platform hanger 3 clamps the formwork platform support column 102 at the annular groove 1021 through the two clamping pins 3026 at the clamp head 3024. Then the formwork platform 1 is lifted, and the walking gantry 2 moves to place the formwork platform 1 on each formwork platform station in turn; at this time, according to the design drawings of the precast concrete slab, the formwork platform 1 is marked, the side formwork (edge ​​formwork) is supported, the steel bars are tied, the embedded parts are placed, and the drawings are checked again, and after being accurate, the concrete is poured.

[0093] 3) Pouring concrete: Figure 4 As shown, a placing machine 5 is connected to the gantry sling 4 of the traveling gantry 2, the traveling gantry 2 moves along the traveling track, and the placing machine 5 places and pours concrete on each mold platform 1;

[0094] Specifically, the gantry sling 4 is connected to the connecting ring 505 on the upper part of the material placing boom 5, the material placing boom 5 is lifted to a suitable height, the fixed beam 502 is locked with the gantry side support or column, and then the material is connected.

[0095] 4) Molding: Figure 21-22 As shown, a precast concrete slab 8 is formed on a mold platform 1, and a plurality of hanging points 9 are pre-installed on the precast concrete slab 8;

[0096] Since the precast concrete slabs 8 are of different sizes, some of the formwork support columns 102 will be cast in the concrete (in this embodiment, two or two rows are cast in the component), and they need to be protected so that they can be easily separated from the concrete when the finished product is demoulded. The general method is to apply a release agent or place an isolation sleeve before pouring. At this time, the concrete slab is a semi-finished product, uncured, and has no strength; the pre-installed hanging points 9 of the precast concrete slab 8 are generally bent hook steel bars, stirrup bars or truss bars, and the hanging points 9 are evenly distributed on the top of the concrete slab.

[0097] 5) Shift and stack: Fig.23 As shown, the formwork platform hoist 3 is connected to the gantry sling 4 of the traveling gantry 2, and the formwork platforms 1 are lifted by the formwork platform hoist 3 and stacked on the formwork platform base 6 in sequence. The upper formwork platform 1 is supported by the formwork platform support column 102 on the lower formwork platform 1.

[0098] 6) Relocation maintenance: Fig.24As shown, the mold base 6 and the mold base 1 stacked thereon are lifted by the gantry sling 4 of the traveling gantry 2 and moved to the maintenance station;

[0099] Specifically, after the formwork platform 1 is stacked to the designed number of layers, the steel frame on the top of the gantry lowers the base sling, and the whole stack is moved to the curing station; the whole stack is covered with a curing cover, which is generally made of tarpaulin, plastic film and other materials, and its main purpose is to prevent the unsolidified concrete from losing water and cracking. If you want to achieve the demoulding strength as soon as possible, you can pass high-temperature steam in the cover to accelerate the solidification process of the concrete; because it is a whole stack curing, the requirements for the curing station are not high, and the curing stations can be centralized or dispersed, which is very flexible and efficient.

[0100] 7) Finished product demoulding: Fig.25 As shown, the demoulding sling 7 is connected to the gantry sling 4 of the traveling gantry 2, and the demoulding sling 7 sequentially hooks the multiple lifting points 9 on the precast concrete slab 8 through the multiple hooks 7024 on the pulley block 702, tightens the gantry sling 4 and lifts according to the operating procedures;

[0101] Specifically, after the concrete slab has been cured for a certain period of time and has reached the corresponding designed strength, it can be demolded. Demolding means separating the finished product from the formwork 1. At this time, the concrete slab is a finished product; the walking gantry 2 hangs down the demoulding hanger 7, and the multiple hooks 7024 of the pulley block 702 are evenly hooked on the corresponding hanging points 9 in turn.

[0102] 8) Transport of empty mold pallets: Fig.26 As shown, after the mold is removed, the mold platform is cleaned; the mold platform hoist 3 is connected to the gantry sling 4 of the walking gantry frame 2, and the mold platforms 1 are stacked on the mold platform base 6 in sequence through the mold platform hoist 3. Then the whole stack is lifted by the gantry hanging rope and transferred from the mold removal area to the casting area. The empty mold platforms are stacked and arranged near the casting station for use at any time.

[0103] Cycle in sequence.

[0104] The present invention can realize a precast concrete component production method with low input, high output, quick effect, easy promotion and low energy consumption, which will definitely have a huge impact on the promotion and application of prefabricated buildings in my country, and at the same time achieve both economic and social benefits.

[0105] The above description is only an embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, expansion, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
