Description

Technical Field

[0001] The present invention belongs to the technical field of concrete slab production equipment, and particularly relates to a manufacturing mold for autoclaved aerated concrete slabs. Background Art

[0002] In the modern construction industry, autoclaved aerated concrete slabs are widely used in the walls, roofs and other structures of various buildings due to their many excellent properties such as light weight, heat insulation, and sound insulation. However, there are still some problems to be solved urgently in the current manufacturing process of autoclaved aerated concrete slabs, especially in the manufacturing mold link.

[0003] The existing manufacturing molds for autoclaved aerated concrete slabs have significant defects in the aspect of material addition. The traditional operation methods are mostly manual or semi-manual addition of raw materials such as cement, sand, and lime, which makes it difficult to accurately control the material addition process. On the one hand, manual operation is extremely prone to deviations in the addition amount of each material due to factors such as individual differences and fatigue of workers, thus affecting the stability of product quality. For example, if the cement addition amount is too much, the concrete slab will be too hard and its brittleness will increase; if the lime addition amount is insufficient, the curing effect of the product may be poor and the strength may not meet the standard. On the other hand, this low-efficiency material addition method seriously restricts the production progress. Adding materials one by one not only consumes a large amount of manpower, but also prolongs the production cycle of a single mold, and it is difficult to meet the requirements of large-scale and high-efficiency modern production. In addition, the traditional mold structure fails to fully consider the optimization of the material addition sequence and process, resulting in uneven mixing of materials in the mold. This not only affects the consistency of the internal structure of the concrete slab, but also reduces the overall performance of the product, such as uneven strength distribution, and it is easy to have local damage during use. In view of the above problems, the present invention provides a manufacturing mold for autoclaved aerated concrete slabs. Summary of the Invention

Detailed implementation manners

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment: As Figure 1 —— Figure 11 shown, a manufacturing mold for autoclaved aerated concrete slabs includes an outer frame 1. A forming frame 2 is fixedly installed inside the outer frame 1. Two groups of symmetrically arranged feeding holes 5 are provided on the forming frame 2. Each group of feeding holes 5 includes five feeding holes 5. Each feeding hole 5 communicates with a feeding pipe 6. A plurality of vertical grooves 3 are provided on the forming frame 2. The vertical grooves 3 are slidably matched with the positioning plates 11. Four linearly arranged steel meshes 12 are detachably installed on the positioning plates 11. The raw materials of the concrete slab are fed into the forming frame 2 through the feeding pipes 6, so that the concrete slab is formed between the forming frame 2 and the steel meshes 12.

[0027] As Figure 1 — Figure 5 shown, the forming frame 2 is fixedly installed on the outer frame 1. During the forming process of the concrete block, first, the steel meshes 12 are sequentially inserted into the positioning plates 11 along the transverse grooves on the positioning plates 11. There will be a distance between the four steel meshes 12. The distance between every two adjacent steel meshes 12 is used to fill the remaining materials. After the four steel meshes 12 are pushed onto the positioning plates 11, the four positioning plates 11 are respectively aligned with the four vertical grooves 3 on the forming frame 2 and the positioning plates 11 slide downward along the vertical grooves 3, so that the positioning plates 11 and the steel meshes 12 move into the interior of the forming frame 2.

[0028] A plurality of bolts 4 are fixedly installed on the forming frame 2. During the forming process of the concrete slab, the cover plate 13 is fixed above the forming frame 2 through the bolts 4 and nuts. After the positioning plate 11 and the steel mesh 12 are placed, the holes on the cover plate 13 are aligned with the bolts 4 on the forming frame 2, so that the cover plate 13 contacts the upper surface of the forming frame 2, and then the cover plate 13 is fixed above the forming frame 2 through the nuts and bolts 4.

[0029] After the steel mesh 12 and the cover plate 13 are both arranged, the pouring and forming of the concrete slab begins. First, select the feed pipe 6 communicating with the lowermost feed hole 5, pour the required materials into the feed hole 5 through the feed pipe 6, and flow into the forming frame 2 through the lowermost feed hole 5. At this time, the materials will enter between the lowermost steel mesh 12 and the forming frame 2. After the materials are solidified and formed, then use the feed pipe 6 communicating with the second-lowermost feed hole 5 from the bottom to transport materials into the forming frame 2. Similarly, after the materials are solidified, continue the next feeding and forming. The entire forming process is from bottom to top, pouring in sequence. In addition to the steel mesh 12, the materials of the concrete slab also include cement, sand, lime, etc., all of which enter the forming frame 2 through the feed pipe 6. The steel mesh 12 is treated with anti-corrosion.

[0030] After the forming is completed, remove the nuts from the bolts 4, and then remove the cover plate 13 from above the forming frame 2.

[0031] Autoclaved aerated concrete block (AAC) is a new type of green and environmental protection building material, which is mainly made of siliceous materials (such as quartz sand, fly ash, tailings powder, etc.) and calcareous materials (such as cement, lime, etc.), and added with blowing agents (such as aluminum powder), foam stabilizers and other additives. The density is usually between 300-800 kg / m³, only 1 / 4-1 / 5 of ordinary concrete, which can effectively reduce the self-weight of the building, reduce the cost of the foundation and structure, and is also convenient for handling and construction.

[0032] During the production process, pressurization is used to make the internal structure of concrete tighter. During the autoclaving process, the specific pressure environment can promote the hydration reaction of cement and other cementitious materials to produce more dense hydration products. These products fill the pores of concrete, greatly reducing the porosity, thereby improving the strength and durability of the concrete slab. For example, in actual engineering applications, concrete slabs that have been properly autoclaved are less likely to deform, crack, and other problems when they are subjected to building structure loads for a long time, which can effectively ensure the safety and stability of the building. Aeration is used to give concrete lightweight and thermal insulation properties. After adding a gasifier (such as aluminum powder) to the concrete raw materials, the gasifier will react chemically with alkaline substances to produce hydrogen and form numerous tiny bubbles. These bubbles are evenly distributed in the concrete, like tiny insulation cavities, which significantly reduce the density of the concrete, making it lightweight and reducing the overall weight of the building. At the same time, the presence of bubbles increases thermal resistance, greatly improving the thermal insulation performance of the concrete slab. During the use of the building, it can effectively reduce indoor and outdoor heat transfer, reduce building energy consumption, and improve living comfort.

[0033] The molding frame 2 is provided with five linearly arranged rectangular grooves 7, which are arranged along the depth direction of the molding frame 2. A closing plate 8 is slidably mounted on each rectangular groove 7, and a slope 9 is provided on one side of the closing plate 8. The closing plate 8 is slidably matched with the outer frame 1, and a return spring 10 is provided between the closing plate 8 and the outer frame 1.

[0034] like Figure 1 , Figure 2 , Figure 4 As shown, the forming frame 2 is provided with five rectangular grooves 7, each of which is slidably matched with a closing plate 8. In the process of forming the concrete block, in the initial state, the left side of the closing plate 8 (with Figure 4 The angle of view is based on the angle of view of the closure plate 8 and the molding frame 2 is tightly attached together. At this time, the inclined surface 9 set on the closing plate 8 is inserted into the rectangular groove 7, that is, the interior of the molding frame 2 is sealed at this time. After the material is added to the molding frame 2 through the feed pipe 6, the molding frame 2 will be pressurized and gasified through the feed pipe 6. At this time, the pressure of the added uncured material in the molding frame 2 will increase. When the pressure in the molding frame 2 is too large, the pressure will push the closing plate 8, so that the closing plate 8 slides on the outer frame 1, and the inclined surface 9 slides in the direction away from the rectangular groove 7, so that the inclined surface 9 gradually leaves the rectangular groove 7. The original state of the inclined surface 9 inserted into the rectangular groove 7 to make the molding frame 2 closed changes, and the gas in the molding frame 2 will flow out through the gap between the closing plate 8 and the rectangular groove 7. In this process, the reset spring 10 will be stretched to generate elastic force. The function of the reset spring 10 is to assist the closing plate 8 in resetting when the pressure in the molding frame 2 is equal to the external pressure.

[0035] A rotating plate 20 is rotatably mounted on the forming frame 2. The rotating plate 20 is located on the surface of the forming frame 2 opposite to the surface where the rectangular groove 7 is located. The rotating plate 20 is slidably engaged with the telescopic plate 21. The telescopic plate 21 is fixedly connected to the connecting rod 22. The connecting rod 22 is fixedly connected to the sliding rod 23. A circular hole 30 is provided on each side of the sliding rod 23. Two symmetrically arranged rectangular holes 29 are provided around each circular hole 30, and the rectangular holes 29 communicate with the circular holes 30. When the circular hole 30 on the sliding rod 23 is connected to the positioning component, the long side direction of the rotating plate 20 is parallel to the bottom surface of the outer frame 1. Two symmetrically arranged arc-shaped grooves 32 are provided on the outer frame 1, and a second straight groove 33 is provided above the arc-shaped grooves 32. The arc-shaped grooves 32 are smoothly connected to the second straight groove 33.

[0036] As Figure 2 , Figure 6 , Figure 8 , Figure 11 shown, during the process of concrete block forming, the rotating plate 20 is in contact with the forming frame 2, making the inside of the forming frame 2 a sealed space. When the pouring is completed and the concrete block needs to be taken out, it is necessary to rotate the rotating plate 20 relative to the forming frame 2, so that the rotating plate 20 rotates from the vertical state to the horizontal state (as the state of the rotating plate 20 in Figure 2 , Figure 6 is horizontal). During the process of the rotating plate 20 changing from the vertical state to the horizontal state, the staff will push the handles at both ends of the sliding rod 23, and push the sliding rod 23 to slide along the arc-shaped groove 32 on the outer frame 1, so that the rotating plate 20 rotates on the forming frame 2, from the vertical state to the horizontal state. First, it will rotate to the upper end of the arc-shaped groove 32. The arc-shaped groove 32 is in smooth contact with the second straight groove 33. Therefore, push the sliding rod 23 upward again, so that the sliding rod 23 slides upward along the second straight groove 33. Since the rotating plate 20 is slidably engaged with the telescopic plate 21, there will be relative sliding between the rotating plate 20 and the telescopic plate 21 at this time, so as to ensure that the sliding rod 23 slides on the second straight groove 33, and finally the sliding rod 23 slides to the positioning component to complete the positioning of the rotating plate 20 and keep the rotating plate 20 in a horizontal state.

[0037] The positioning component includes two symmetrically arranged locking rods 26. The locking rods 26 are slidably mounted on the outer frame 1. One end of the locking rod 26 is fixedly installed with a limiting block 31, and the other end of the locking rod 26 is provided with a rotating part. Through the rotating part, the locking rod 26 rotates so that the limiting block 31 adapted to the rectangular hole 29 does not coincide with the rectangular hole 29. The rotating part includes two symmetrically arranged inclined slots 27 provided on the locking rod 26. A first straight slot 28 is arranged between the two inclined slots 27. The first straight slot 28 is provided on the locking rod 26, and both ends of the first straight slot 28 are smoothly connected to the two inclined slots 27 respectively. The locking rod 26 or the inclined slot 27 is slidably matched with one end of the ball head rod 25. The other end of the ball head rod 25 is fixedly connected to the tripod 24, and the tripod 24 is fixedly installed on the outer frame 1.

[0038] As Figure 7 — Figure 10 shown, during the process of the sliding rod 23 sliding upward along the second straight slot 33, the upper part of the locking rod 26 is pulled upward, so that the inclined slot 27 located below the locking rod 26 slides relative to the ball head rod 25. Since the inclined slot 27 is in an inclined state, the ball head rod 25 will cause the locking rod 26 to rotate, so that the limiting block 31 is aligned with a rectangular hole 29. In this way, the circular hole 30 on the sliding rod 23 smoothly passes through the lower part of the locking rod 26, and the rectangular hole 29 passes through the limiting block 31. At this time, the ball head rod 25 moves to the position where the first straight slot 28 is located, and the locking rod 26 stops rotating. When the locking rod 26 moves upward to the position where the inclined slot 27 below contacts the ball head rod 25, the ball head rod 25 will cause the locking rod 26 to rotate again. In this way, the limiting block 31 will rotate to a position where it does not coincide with any rectangular hole 29. At the same time, the end of the inclined slot 27 contacts the ball head rod 25, and the locking rod 26 remains stationary. In this way, the sliding rod 23 is blocked by the limiting block 31, and the sliding rod 23 will not drive the rotating plate 20 to move, so that the rotating plate 20 maintains a horizontal state.

[0039] A baffle 14 is rotatably installed on the outer frame 1. A torsion spring 15 is arranged at the connection between the baffle 14 and the outer frame 1. And two first positioning rods 16 are fixedly installed on one side of the baffle 14 close to the forming frame 2. The first positioning rods 16 are slidably matched with the second positioning rods 18, and a second return spring 17 is arranged between the first positioning rods 16 and the second positioning rods 18. A limiting piece 19 is fixedly installed on the second positioning rods 18.

[0040] As Figure 1 、 Figure 6As shown, during the process of pouring the concrete block, the baffle 14 is in a vertical state. And during the process of the rotating plate 20 rotating to the vertical state, the sliding rod 23 will also rotate. The sliding rod 23 will push the limiting piece 19, so that the limiting piece 19 drives the positioning rod two 18 to slide along the bottom of the outer frame 1 in a direction away from the positioning rod one 16. After the sliding rod 23 stops moving, the sliding rod 23 still contacts the limiting piece 19. The purpose of doing this is to block the limiting piece 19 by the sliding rod 23, so that the baffle 14 cannot rotate. In this way, the baffle 14 and the outer frame 1 form a complete space to ensure the safety of the surrounding environment. To prevent the baffle 14 from being accidentally touched and opened during the production of the concrete block, which may cause harm to the surrounding environment or people. In order to improve the sealing performance, the rotating plate 20 can be made of a magnetic material, and at the same time, the forming frame 2 is also made of a magnetic material, so that the fitting of the rotating plate 20 and the forming frame 2 is closer.

[0041] After the pouring is completed, the rotating plate 20 rotates to the horizontal state, and the limiting piece 19 will not be blocked by the sliding rod 23. Then the baffle 14 can be rotated so that the baffle 14 rotates from the vertical state to the horizontal state. The function of the coil spring 15 is to assist the reset of the baffle 14. The positioning rod two 18 approaches the positioning rod one 16 under the action of the reset spring two 17. After the rotating plate 20 and the baffle 14 are both in the horizontal state, the concrete plate in the forming frame 2 can be taken out by tools such as a manipulator. The bottom of the forming frame 2 can adopt a smooth design to prevent the concrete plate from adhering to the inner bottom of the forming frame 2, which affects the work of taking out the concrete plate. This belongs to the prior art and can be adopted by those skilled in the art.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; under the idea of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as above. For the sake of brevity, they are not provided in detail; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
