[0002] In recent years, with the continuous development of prefabricated buildings, the application of precast laminated slabs has become more and more extensive. At present, steel molds are mainly used for the production of laminated slabs. Due to the variety of sizes and specifications of laminated slabs, the number and types of laminated slabs are also complex, resulting in low mold installation efficiency and great difficulty in mold management. Moreover, since the steel molds are customized according to the size of the laminated slabs, the degree of generalization is low, increasing the mold amortization cost. Therefore, a new type of mold must be adopted to solve the problems of high cost and low generalization degree of steel molds.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0040] A general mold for producing non-reinforced precast composite slabs, including a bottom plate 100, further including:

[0041] The first slurry retaining unit 1, placed at the upper end of the bottom plate 100, is used to block both ends of the concrete for pouring the composite slab.

[0042] The second slurry retaining unit 2 includes a side slurry retaining assembly 21 provided on one side of the first slurry retaining unit 1 for blocking both sides of the concrete for pouring the composite slab, and an adjusting assembly 22 provided on the upper part of the side slurry retaining assembly 21 for adjusting the relative position between the side slurry retaining assembly 21 and the first slurry retaining unit 1. A square area is formed between the side slurry retaining assembly 21 and the first slurry retaining unit 1.

[0043] As an improvement, the first slurry retaining unit 1 includes:

[0044] Two groups of first slurry retaining plates 11 are arranged in parallel at the upper end of the bottom plate 100.

[0045] Multiple groups of limiting blocks are arranged at equal intervals on one side of the first slurry retaining plate 11 and are used for pouring limit when pouring composite slabs of different widths.

[0046] The first guide pieces 13 are fixedly connected to both ends of the first slurry retaining plate 11.

[0047] Furthermore, two groups of second slurry retaining plates 211 are respectively located at both ends of the first slurry retaining plate 11 and are used for pouring limit when pouring composite slabs of different lengths.

[0048] The second guide plate 212 is fixedly connected to both ends of the second baffle 211;

[0049] The fastening mechanism 213 is arranged on the upper part of the second baffle 211 and is used to lock the first baffle unit 1 and the second baffle unit 2.

[0050] Furthermore, the fastening mechanism 213 includes:

[0051] There are multiple groups of carrier frames 2131, and the carrier frames 2131 are fixedly connected to one side of the second baffle 211 at equal intervals. The carrier frames 2131 are at the same height as the plane where the upper ends of the first baffle plates 11 are located;

[0052] The bolts 2132 are fixedly connected to the upper ends of the carrier frames 2131;

[0053] The first pressing plate 2134 is sleeved on the outside of the bolts 2132 in a vertically sliding manner and is used to press the adjusting assembly 22;

[0054] The locking nuts 2133 are threadedly connected to the outside of the bolts 2132 and are located above the first pressing plate 2134 and are used to press the first pressing plate 2134. A gap for accommodating concrete is provided between the carrier frames 2131 and the bottom plate 100.

[0055] Among them, the adjusting assembly 22 includes:

[0056] The second pressing plate 221 is arranged between the carrier frames 2131 and the first pressing plate 2134 and is used to synchronously press the adjusted first baffle plates 11 and the carrier frames 2131;

[0057] The first guide groove 222 is arranged at the upper end of the second pressing plate 221 and is used to guide the movement adjustment of the second pressing plate 221 along the bolts 2132.

[0058] In addition, the adjusting assembly 22 further includes:

[0059] The push block 223 is fixedly connected to one end of the second pressing plate 221;

[0060] The second guide groove 2231 is arranged at the lower end of the push block 223 and is used to cooperate with the limiting plate 12 to limit the first baffle plate 11.

[0061] It should be added that in the present utility model, the pouring height of the concrete is lower than the lower end of the carrier frames 2131, so as to prevent the concrete from solidifying with the carrier frames 2131, resulting in great difficulty in demolding the subsequent composite slabs.

[0062] It should be noted that: in the specific implementation process of the present utility model, two first slurry retaining plates 11 are placed in parallel on the bottom plate 100, and then two second slurry retaining plates 211 are placed in parallel on the bottom plate 100, so that an "open" character area is formed between the two first slurry retaining plates 11 and the two second slurry retaining plates 211. Then, the corresponding second pressing plates 221 are pushed along the bolts 2132 respectively. The second pressing plates 221 drive the pushing blocks 223 to move until they contact the first slurry retaining plates 11. At this time, the second guide grooves 2231 are sleeved outside the limiting plates 12, so that the first slurry retaining plates 11 are positioned. Then, the locking nuts 2133 are rotated. Under the action of the tangential force of the thread between the locking nuts 2133 and the bolts 2132, the first pressing plates 2134 are pressed downward, so that the bearing frames 2131 and the second pressing plates 221 are fastened together, ensuring that during the pouring process, the second slurry retaining plates 211 connected to one side of the bearing frames 2131 will not slide relative to the first slurry retaining plates 11. Therefore, the installation process of the whole mold is simple and the installation efficiency is high;

[0063] In addition, for pouring laminated boards of different sizes, the present utility model can move the first slurry retaining plates 11 along the inner sides of the two second slurry retaining plates 211 before tightening the locking nuts 2133. The first slurry retaining plates 11 drive the first guide pieces 13 to move along the inner sides of the second pressing plates 221 until the length between the two first slurry retaining plates 11 meets the length of the required laminated board, then stop moving the first slurry retaining plates 11. Then, push the second slurry retaining plates 211 to move along the inner sides of the first slurry retaining plates 11, select the limiting plates 12 corresponding to the pushing blocks 223 according to the width of the required poured laminated board. After adjustment, rotate the locking nuts 2133 to install the first slurry retaining plates 11 and the second slurry retaining plates 211 again, and pour the concrete into the area surrounded by the first slurry retaining plates 11 and the second slurry retaining plates 211, so as to achieve the ability to adaptively adjust according to the required size of the laminated board, with a high degree of generality and reduced use cost of the mold.
