[0002] Hollow floor technology is a new technology that is developing rapidly in my country's construction field and a new trend in the development of the construction industry. Since 2012, my country has formulated industry standards JQJ / T 268--2012 "Technical Specifications for Cast-in-Place Concrete Hollow Floors", JG / 352-2012 "Cast-in-Place Concrete Hollow Structure Hole Forming Core Mold", and JC / T2472-2018 "Gypsum Mold Box for Cast-in-Place Concrete Hollow Structure". At present, this technology has been widely promoted and applied in the construction industry.

[0003] Gypsum mold box for cast-in-place concrete hollow structure JC / T2472-2018 (hereinafter referred to as gypsum mold box) uses building gypsum GB / T9776-2008 as raw material, adds a certain proportion of water to stir, and then pours into the mold to be formed after solidification (currently the industry generally adds an appropriate amount of fiber to increase the strength).

[0004] Gypsum mold box is a new type of industrial by-product building material strongly advocated by the country. It is an effective way to solve environmental pollution and turn waste into treasure. At present, the domestic production of gypsum mold box basically adopts a simple mode of manual mold addition. Its main disadvantages are high labor intensity and serious environmental pollution in production operations (gypsum dust, waste residue), which not only causes harm to the workers' bodies but also causes secondary pollution to the environment. This is also the main problem restricting the development of the gypsum mold box building materials industry. Summary of the invention

[0093] In this way, when the above-mentioned vibration table is working, the hollow floor mold is placed on the mold holding station formed on the upper end surface of the bracket; after the hollow floor mold on the mold holding station is placed with materials, the vertical drive control mechanism can control the vertical upward movement of the supporting member, and push the rectangular frame upward through the spring mechanism, so that the rectangular frame abuts against the lower end surface of the hollow floor mold supported on the mold holding station, and transmits the vibration to the hollow floor mold. In this working process, the pressure on the spring mechanism is constantly changing. The greater the amount of compression of the spring mechanism, the stronger the vibration of the hollow floor mold. The vibration frequency can be changed according to the vibration needs. The variable frequency vibration process can not only replace the surface scraping process of the gypsum mold box, save materials, and will not produce excess ash after grouting, but also greatly improve the strength of the product.

[0094] In this specific embodiment, a mounting plate 42 is horizontally disposed on the rectangular frame, and the vibrator is mounted on the lower surface of the mounting plate.

[0097] In this way, during the working process, a guiding structure is provided between the rectangular frame and the bracket, the design is more reasonable, and the two are not easily misaligned.

[0098] In this specific embodiment, vertically upward positioning pins 46 are respectively provided at the four corner positions on the upper surface of the rectangular frame, and the positioning pins can be correspondingly inserted into the positioning holes provided on the lower end surface of the hollow floor mold.

[0099] In this way, the hollow floor mold can be better placed above the rectangular frame, and during the vibration process, the hollow floor mold can be better positioned to prevent it from sliding out of the rectangular frame. Further, a ring-shaped pad made of rubber material is sleeved on the positioning pin.

[0100] In this specific implementation manner, there are four spring mechanisms distributed in a rectangular shape in the horizontal direction, and the upper ends of the spring mechanisms are connected to the four corner positions below the rectangular frame in a one-to-one correspondence.

[0105] In this way, the whole structure is simpler, and the size of the pedal force can produce different vibration forces and vibration frequencies. The operator determines the size of the force and the vibration time according to the surface flatness of the slurry injected into the mold.

[0106] In this specific implementation, a pedal 50 is provided at the driving end.

[0107] In this way, the design is more reasonable and more convenient to use.

[0108] In this specific embodiment, a support column 51 is provided in the middle of the support member and is arranged vertically downward. The lower end of the support column is a ball head structure and is used to abut against the driving end for support.

[0109] In this way, the structure is simpler and can better drive the supporting frame to move vertically upward.

[0110] In summary, the above equipment has the following characteristics in operation:

[0111] 1. The transportation, weighing and mixing of gypsum powder are carried out in a fully closed state, and there is no dust in the production process.

[0112] 2. The volume of the mold cavity is larger than the volume of the injected gypsum slurry. The surface self-leveling of the gypsum slurry injected into the mold is completed by vibration instead of the scraping process, and there is no residue in the production process.

[0113] 3. During the process of filling the mold with gypsum slurry, vibrating it can achieve tight filling, reduce pores and internal defects, and thus improve the strength of the gypsum mold box.
