Description

Technical Field

[0001] The invention relates to the field of assembled building component moulds, and in particular to a high-efficiency blocking method for a universal mould for assembled composite panels. Background Art

[0002] In the production of prefabricated building components, the sealing of prefabricated composite board molds is a key link, which directly affects the quality and production efficiency of the components. At present, the commonly used sealing technology in the industry is mainly the rubber plug single-hole sealing technology: this technology uses a rubber plug to individually seal each hole of the mold. However, the rubber plug is easy to harden after contacting the concrete, which makes disassembly and assembly difficult, and its turnover rate is low. In addition, since each hole needs to be operated separately, for a large number of composite boards, the workload of assembly and disassembly is large and the efficiency is low. At the same time, if the mold is not cleaned thoroughly or the worker operates improperly, the rubber plug may not be installed correctly, which will cause leakage and hollowing of the edge of the component.

[0003] The problems of the above-mentioned prior art mainly include: high cost, low efficiency and potential component quality problems caused by plugging materials and methods. These problems affect the reliability and economy of the production of prefabricated building components, and an improved efficient plugging method for the universal mold of prefabricated composite panels is urgently needed to solve these problems. Summary of the invention

[0004] In order to overcome the defects in the above-mentioned prior art, the present invention provides a highly efficient sealing method for a universal mold of an assembled composite panel. By using a reusable stop-slurry tape instead of a disposable rubber plug, the consumption of raw materials is reduced and the cost is reduced. The stop-slurry tape can be reused and does not need to be replaced frequently, thereby significantly improving the turnover rate of the mold. The overall sealing method simplifies the operating process, reduces the operating time of workers, and improves production efficiency. The overall sealing reduces the risk of leakage and hollowing of the edge of the component, thereby improving the overall quality of the component.

[0005] Technical Solution

[0006] An efficient plugging method for a universal mold of an assembled composite plate comprises the following steps:

[0007] Step 1: Assemble the composite board mold: Assemble the molds of various parts on the mold table according to the design requirements of the prefabricated components, ensuring that all joints are tight and without gaps;

[0008] Step 2: Tie the steel bars: complete the steel bar tying work according to the design requirements;

[0009] Step 3: Wrap the stop tape: Wrap the prepared stop tape around the periphery of the mold to ensure that all parts that need to be sealed are covered;

[0010] Step 4: Fix the stop tape: Use an electric wrench and bolts to fix the stop tape on the mold to ensure that it does not shift;

[0011] Step 5: Concrete pouring: After ensuring complete sealing and fixation, start pouring concrete. During the entire pouring process, monitor the position and pressure of the grout stop to ensure that there is no leakage.

[0012] Step 6: Demolding: After the concrete reaches a certain strength, demolding operation is carried out.

[0013] Furthermore, the binding work in step 2 is as follows: the steel bars are placed inside the grooves between the limiting plates on the mold so that the steel bars are distributed vertically, and then the intersections of the steel bars are bound by metal wires.

[0014] Furthermore, in step three, the prepared stop grouting tape is wrapped around the periphery of the mold: the stop grouting tape is continuously passed through the gaps between the limiting plates, so that the stop grouting tape is fixed to the mold by relying on the limiting plates and is located on the upper side of the steel bar.

[0015] Furthermore, in step four, an electric wrench and bolts are used to fix the stop tape on the mold: the tail of the stop tape is penetrated by the bolt, and the bolt is screwed into a pre-set threaded hole on the mold table to fix it, and at the same time, the tail of the stop tape is wrapped around the outside of the head of the stop tape, thereby pressing the head of the stop tape and fixing it with pressure.

[0016] Furthermore, in the demoulding operation in step six, the concrete component can be demoulded by removing the stop strip by loosening the bolts.

[0017] Beneficial Effects

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Cost reduction: By using a reusable stopper tape instead of a disposable rubber plug, the consumption of raw materials is reduced. According to statistics, the use of the blocking device of the present invention can reduce the mold cost by about 30-50%. The specific saving ratio depends on the production scale and material cost.

[0020] 2. Improved turnover rate: Since the stop tape can be reused and does not need to be replaced frequently, the turnover rate of the mold is significantly improved. In actual production, the turnover rate of the mold has increased by about 20-40%;

[0021] 3. Improved production efficiency: The overall plugging method simplifies the operation process and reduces the operating time of workers. In actual operation, the time for installing the plugging device is increased from 10 yuan per person per hour to 25 yuan per person per hour, and the efficiency is increased by 150%;

[0022] 4. Improvement of component quality: Overall plugging reduces the risk of leakage and hollowing of component edges, and improves the overall quality of components. After testing, the qualified rate of components increased from 92% to 98% after using the device of the present invention;

[0023] 5. Environmental protection: It reduces the use of disposable plugging materials, reduces waste emissions during the production process, and contributes to environmental protection;

[0024] 6. Improve worker satisfaction: Due to the simplification of operating procedures and the improvement of efficiency, the labor intensity of workers is reduced, the job satisfaction is improved, which is beneficial to the human resource management of the enterprise.

[0034] Step 4: Fix the stop tape: Use an electric wrench and bolts 6 to fix the stop tape 2 on the mold 4 to ensure that it does not shift;

[0035] Step 5: pouring concrete: after ensuring complete sealing and fixing, start pouring concrete. During the whole pouring process, monitor the position and pressure of the grout stop strip 2 to ensure that there is no grout leakage;

[0036] Step 6: Demolding: After the concrete reaches a certain strength, demolding operation is carried out.

[0037] Furthermore, the binding work in step 2 is as follows: the steel bars 3 are placed inside the grooves between the limiting plates 5 on the mold 4 so that the steel bars 3 are vertically distributed, and then the intersections of the steel bars 3 are bound by metal wires.

[0038] Furthermore, in step three, the prepared stop grouting tape 2 is wrapped around the periphery of the mold 4: the stop grouting tape 2 is continuously passed through the gap between the limiting plates 5, so that the stop grouting tape is fixed to the mold 4 by relying on the limiting plates 5, and is located on the upper side of the steel bar 3.

[0039] Furthermore, in step four, the stop-slurry tape 2 is fixed to the mold 4 using an electric wrench and bolt 6: the tail of the stop-slurry tape 2 is penetrated by the bolt 6, and the bolt 6 is screwed into a pre-set threaded hole on the mold platform 1 for fixation, and at the same time, the tail 8 of the stop-slurry tape 2 is wrapped around the outside of the head 7 of the stop-slurry tape, thereby pressing the head 7 of the stop-slurry tape 2 and fixing it with pressure.

[0040] Furthermore, in the demoulding operation in step six, the concrete component can be demoulded by removing the stop strip 2 by releasing the bolts 6 .

[0041] Specifically,

[0042] (I) Material selection and preparation

[0043] The stopper strip 2 is made of durable synthetic rubber material with a width of 40 mm and a length customized according to the mold size. In addition, an electric wrench and M12 tapping are required to meet the needs of different templates.

[0044] (2) Mold preparation

[0045] 1. Formwork platform positioning: according to the prefabricated component drawings, lay out and mark the corresponding bed hole positions on the formwork platform 1;

[0046] 2. Punching and tapping: Punch a 10.5 mm hole at the marked position and perform M12 tapping in the drilled hole so that the subsequent bolt 6 can fix the stop strip 2;

[0047] (III) Assembly and plugging operations

[0048] 1. Assemble the composite panel mold: According to the design requirements of the prefabricated components, assemble the molds 4 of each part to ensure that all joints are tight and without gaps;

[0049] 2. Tie the steel bars: tie the steel bars 3 in the mold according to the design requirements;

[0050] 3. Wrapping the stop tape: Wrap the prepared stop tape 2 around the periphery of the mold 4 to ensure that all the parts that need to be sealed are covered;

[0051] 4. Fix the stop grout strip: Use an electric wrench and M12 bolt 6 to fix the stop grout strip 2 on the die table 1, and tighten the stop grout strip 2 through the pre-punched holes to ensure that it does not shift;

[0052] (IV) Casting and demoulding

[0053] 1. Concrete pouring: After ensuring complete sealing and fixing, start pouring concrete. During the entire pouring process, monitor the position and pressure of the grout stop strip 2 to ensure that there is no leakage;

[0054] 2. Demoulding: After the concrete reaches a certain strength, demoulding operation is performed. Since the stop grouting strip 2 is fixed by bolts 6, the stop grouting strip 2 can be quickly removed by releasing the bolts 6, and then the concrete component can be demoulded smoothly.

[0055] The present invention uses a reusable stopper tape instead of a disposable rubber plug, thereby reducing the consumption of raw materials and lowering costs. The stopper tape can be reused and does not need to be frequently replaced, thereby significantly improving the turnover rate of the mold. The overall sealing method simplifies the operating process, reduces the operating time of workers, and improves production efficiency. The overall sealing reduces the risk of leakage and hollowing of component edges, and improves the overall quality of the component.
