Description

Technical Field

[0001] The invention relates to the technical field of prefabricated buildings, and in particular to a production mould for a prefabricated beam with a wall and a mould manufacturing method. Background Art

[0002] In the production of prefabricated components, most prefabricated companies use sidewall molds for prefabricated beams and walls, which are basically made of steel plate bending or steel and aluminum cutting. The mold material cost is high and the processing cycle is long. After the bending is completed, in order to ensure the roughness of the wall surface around the beam and wall, it is necessary to add a water-washed surface or install patterned plates and other materials inside the mold. There are many processing steps and the mold is heavy, which is very unfavorable for the transportation, installation and production of the mold in the later stage. In addition, the sidewall reinforcement opening processing of the prefabricated beam and wall mold mostly adopts the long hole process. This process has high requirements on the accuracy of beam stirrup binding and the size of the reinforcement opening must be larger than the size of the beam stirrup so that the beam stirrup can be smoothly installed in place. This leads to difficulties in positioning and installing the steel cage in the later production of components and it is easy to cause the problem of concrete leakage. Therefore, it is necessary to manually adjust the stirrup spacing and concrete plugging operations, which increases labor costs and reduces production efficiency. In addition, for low-rise prefabricated buildings, the mold turnover rate is greatly reduced, thereby greatly increasing the proportion of mold costs, which is not conducive to the cost control of prefabricated buildings. With the rapid development of prefabricated buildings, this problem needs to be solved urgently. Summary of the invention

[0003] The purpose of the present invention is to provide a production mold for a prefabricated beam with wall and a mold manufacturing method to solve the problems of high cost of existing mold materials, long processing cycle, multiple processes, large weight, and inconvenience in later transportation, installation and production.

The left closing net is fixed tightly to the left side of the upper fixed frame and the lower fixed frame, and the right closing net is fixed tightly to the right side of the upper fixed frame and the lower fixed frame. The lower closing net is fixed tightly to the lower part of the upper fixed frame and the lower fixed frame. The mesh cage is placed in a frame composed of the upper fixed frame, the lower fixed frame and the upper closing net, the lower closing net, the left closing net and the right closing net, and is fixedly connected to the beam reinforcement cage, the lower closing net, the left closing net and the right closing net.

[0010] The present invention also provides a method for manufacturing a production mold for a prefabricated beam with wall, which comprises the following steps in sequence:

[0011] S1. Tie and shape the beam reinforcement cage according to the drawings, determine the arrangement spacing of the stirrups, process the upper closing net according to the arrangement spacing of the stirrups, and tie and fix the upper closing net with the stirrups and positioning steel bars of the beam reinforcement cage;

[0012] S2, the upper square tube of the upper fixed square frame is arranged parallel to and fixed to the upper square tube of the lower fixed square frame, the stirrups of the beam reinforcement cage tied with the upper closing net are passed between the upper square tube of the upper fixed square frame and the upper square tube of the lower fixed square frame, and the upper closing net is fixed closely to the upper square tube of the upper fixed square frame and the upper square tube of the lower fixed square frame;

[0013] S3. Process the left and right closing nets according to the position of the bottom reinforcement. The two ends of the bottom reinforcement of the beam reinforcement cage pass through the left and right closing nets respectively. The left square tube, right square tube and lower square tube of the lower fixed frame are positioned and fixed. Then the left square tube, right square tube and lower square tube of the upper fixed frame are fixed to the left square tube, right square tube and lower square tube of the lower fixed frame respectively. The left closing net is fixed closely to the left square tube of the upper fixed frame and the left square tube of the lower fixed frame. The right closing net is fixed closely to the right square tube of the upper fixed frame and the right square tube of the lower fixed frame. The lower closing net is fixed closely to the lower square tube of the upper fixed frame and the lower square tube of the lower fixed frame.

[0014] S4. Place the mesh cage in a frame consisting of an upper fixed frame, a lower fixed frame, and upper closing nets, lower closing nets, left closing nets, and right closing nets, and fix it to the beam reinforcement cage, lower closing nets, left closing nets, and right closing nets.

[0015] Preferably, in step 1, the method for processing the upper closing net according to the arrangement spacing of the stirrups is to cut the upper closing net according to the length and width of the beam, and cut stirrup notches on the two long sides of the upper closing net according to the arrangement spacing of the stirrups.

[0016] Preferably, the method for processing the left closing net and the right closing net according to the position of the bottom rib in step 3 is to cut the left closing net and the right closing net according to the height of the upper fixed frame and the lower fixed frame and the distance between the upper fixed frame and the lower fixed frame, and cut the bottom rib notches on the two long sides of the left closing net and the right closing net according to the position of the bottom rib.

[0020] The closing net is easy to process and can be directly processed with simple tools. The processing cycle is short, the process is few, and the weight is light, which is conducive to the processing and production of workers and the subsequent transportation, installation and production;

[0021] When processing the closing net, only the stirrups and bottom bars that pass through the closing net need to be cut, and the opening area is reduced, which solves the problem of concrete leakage during component production, reduces labor costs, and greatly improves production efficiency;

[0022] For low-rise prefabricated buildings, there is no need to process traditional molds. The new molds can be recycled by simply adjusting the length of the fixed square tube according to the external dimensions of different components, which greatly improves the utilization rate and versatility of the molds, solves the problem of reduced mold turnover rate, reduces the proportion of mold costs, and is conducive to production cost control;

[0023] And due to the special structural structure of the closing net, after the concrete is poured, it will precipitate out from the inside to the outside and match the rough surface of the closing net. The roughness of the end face of the produced wall panel can reach more than 80%, thereby eliminating the production process of adding water-washed surfaces or installing patterned plates and other materials inside the mold in the later stage, greatly saving the labor cost and material cost of producing components and promoting the good development of prefabricated buildings.
