Description

Technical Field

[0001] The invention relates to the technical field of concrete block production, and in particular to an autoclaved concrete block die assembly and a use method. Background Art

[0002] Concrete blocks are basically divided into regular blocks and special-shaped blocks. Regular blocks refer to blocks with a rectangular structure, and special-shaped blocks refer to blocks with non-rectangular structures. Generally speaking, regular blocks are in greater demand, and regular blocks are divided into solid blocks and hollow blocks. Solid blocks are cut after pouring large concrete blocks. In contrast, the production of hollow blocks requires independent mold making, which is much more complicated.

[0003] Hollow blocks have a wide range of uses. Air, sound insulation, fire prevention and other materials can be filled inside them. They are often used to make non-load-bearing sound insulation walls or insulation walls, or to make secondary load-bearing walls. Therefore, under the premise that the compressive strength meets the requirements, the production of hollow blocks should follow the principle that the smaller the required load-bearing, the greater the hollowness. From the enterprise level, it can save raw materials, control costs, develop a variety of products of different specifications, form a price gradient, improve product competitiveness, and facilitate market promotion and sales. From the perspective of social resources, it can avoid waste of resources caused by excessive use of materials.

[0004] At present, there are some problems in the production of hollow concrete blocks, which leads to high production costs. On the one hand, there is the mold problem. If you want to produce hollow blocks of various specifications, you need to customize a variety of different molds, which costs a lot of mold costs, and there will be many problems such as mold storage, switching and transportation. Therefore, most companies only produce one or two specifications of concrete blocks when producing autoclaved concrete blocks. On the other hand, there is the problem of static curing. Generally, whether it is solid blocks or hollow blocks, when curing in the static room, the current molds are limited and the ambient temperature of the entire static room is controlled. However, due to the special structure of hollow blocks, the curing method during static curing can be optimized, thereby reducing the input of curing energy. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide an autoclaved concrete block mold assembly and use method, which can realize the production of hollow concrete blocks of different specifications on a basic mold by changing the combination, thereby removing the limitation that a variety of different molds need to be customized to produce products of various specifications, reducing the cost of molds, and avoiding the problems of storage space consumption, switching troubles, and time-consuming transportation caused by too many molds, helping enterprises to improve their competitiveness. At the same time, it can also provide a more efficient maintenance method during static maintenance to avoid wasting production resources.

[0006] The technical solution of the present invention is achieved in this way:

[0007] A autoclaved concrete block mold assembly comprises a base plate and an annular outer wall arranged on the upper surface of the base plate, an annular inner wall is arranged inside the outer wall, the inner wall can be detachably installed inside the outer wall, the bottom of the inner wall is sealed and fitted with the upper surface of the base plate, a certain distance is left between the inner wall and the outer wall so as to clamp and form an annular area, a ventilation heating pipe ring is also arranged in the annular area, an annular rectangular center wall is arranged inside the inner wall, an annular casting area is formed by clamping between the inner wall and the center wall, the length and width of the center wall are changeable, the four outer wall surfaces of the center wall are always smooth surfaces before and after the size changes, the bottom of the center wall is detachably fixedly connected to the upper end surface of the base plate, and the bottom of the center wall is sealed and fitted with the upper surface of the base plate.

[0008] When using this device, according to the size requirements of the required hollow concrete blocks, the size of the inner wall and the size of the center wall are selected, and then the inner wall and the center wall are installed in the outer wall. The annular space between the inner wall and the center wall is the pouring area of ​​the concrete block slurry. After the concrete block slurry is poured into the pouring area, it can be sent to the static stop room for static solidification. During static curing, hot air is provided to the ventilation heating pipe ring to heat the annular area, and the heat is conducted to the concrete slurry through the inner wall. After the solidification is completed, the mold assembly is turned over to make the hollow concrete block come out from the top, and then it is sent to autoclave curing.

[0009] By setting a center wall with adjustable length and width, the size of the hollow area of ​​the hollow concrete block can be adjusted according to demand, so that the production of hollow concrete blocks of different specifications can be completed without changing the mold. In addition, the four outer wall surfaces of the center wall are always smooth after the size changes, so that the inner wall of the cast hollow concrete block will not have ribs or grooves due to the size change of the center wall, avoiding the difficulty of demoulding due to the ribs or grooves getting stuck when the hollow concrete block is demoulded, and also ensuring the structural unity of the hollow concrete block product.

[0010] By setting up the ventilation heating pipe ring, only the ventilation heating pipe ring needs to be heated during static maintenance. If necessary, a film can be covered on the top of the mold assembly to slow down heat loss. The ventilation heating pipe ring avoids heating the entire static room, thereby reducing the input of production energy.

[0011] A further technical solution is that the central wall includes right-angle walls arranged at four corners, the right-angle walls are composed of two mutually perpendicular rectangular plates, and two adjacent right-angle walls are connected by a chain plate, and the chain plate includes a plurality of mutually parallel rectangular long strips, and the outer side walls of the plurality of long strips are arranged to form the outer side wall of the chain plate, and the outer side wall of the chain plate is a rectangular smooth surface, and the inner side walls of two adjacent long strips are hinged by a hinge, and the bottom of the right-angle wall is detachably fixedly connected to the upper end surface of the bottom plate, and the right-angle wall and the top of the adjacent long strips are also detachably fixedly connected by an inner connecting plate.

[0012] When installing the center wall, first calculate the length of the chain plate, and rotate the corresponding number of long strips so that the outer wall of the long strip and the outer wall of the right-angle wall are in the same plane, thereby obtaining a chain plate of corresponding length, and fix the two ends of the chain plate to the top of the right-angle wall through the inner connecting plate to form a fixed rectangular center wall, place the center wall inside the inner surrounding wall, and then fix it to the bottom plate through the bottom wall of the right-angle wall, so that the center wall is fixedly connected to the bottom plate.

[0013] A further technical solution is that the bottom plate is provided with a plurality of first mounting holes that penetrate the upper and lower end surfaces of the bottom plate, and each rectangular plate of the right-angle wall is provided with a penetrating third sliding hole, and the first mounting holes are arranged according to all preset mounting trajectories of the third sliding holes, and the first mounting holes include a circular first sliding hole that communicates with the upper end surface of the bottom plate, and a third threaded hole that is arranged below the first sliding hole and communicates with the lower end surface of the bottom plate, and the diameter of the third threaded hole is smaller than the diameter of the first sliding hole.

The leveling bolt includes a first round rod and a first screw rod that is arranged below the first round rod, the first round rod is slidably inserted in the first sliding hole, and the outer wall of the first round rod is in contact with the inner wall of the first sliding hole, the first screw is screwed in the third threaded hole, and an elastic ring is also sleeved on the first screw, and the elastic ring is arranged between the first round rod and the third threaded hole.

[0014] The third bolt, whose bolt body is a round rod, passes through the third sliding hole and is screwed into the third threaded hole from the bottom of the right-angle wall, thereby pressing the right-angle wall against the upper end surface of the bottom plate. In the first mounting hole where the third screw rod is not screwed, a leveling bolt is set to fill the first mounting hole, and the first screw rod is rotated to gradually lower the first round rod until the upper end surface of the first round rod is flush with the upper end surface of the bottom plate, thereby making the upper end surface of the bottom plate smooth, so as to prevent the concrete slurry from leaking or forming a bulge when poured into the first mounting hole, affecting subsequent processing. By setting an elastic ring, an upward thrust can be provided to the first round rod, thereby adjusting the stretching degree of the first screw rod, so that the first screw rod is in a state that is not easy to rotate, and preventing the first screw rod from rotating due to vibration during the movement of the mold assembly.

[0015] A further technical solution is that a second threaded hole is provided at the center of the top of the long plate, and two through holes are provided on the inner connecting plate. The third bolt is slidably passed through one through hole, and a fourth bolt is slidably passed through the other through hole, and the fourth bolt is screwed into the second threaded hole.

[0016] The third bolt and the fourth bolt pass through the two through holes on the inner connecting plate and are then screwed into the third threaded hole of the bottom plate and the second threaded hole of the long plate, so that the right angle wall and the adjacent long plate are detachably fixed. By setting the second threaded hole at the center of the top of the long hole, the distance between the third sliding hole on the right angle wall and the second threaded hole of the long plate is fixed when assembled, thereby improving the versatility of the inner connecting plate and fixing the size of the inner connecting plate.

[0017] A further technical solution is that the ventilation heating pipe ring includes an intake pipe and an exhaust pipe passing through the outer wall, one end of the intake pipe and the exhaust pipe is located outside the outer wall, and the other end of the intake pipe and the exhaust pipe surrounds the annular area and then is connected to form a ventilation heating pipe ring.

[0018] By providing a ventilation heating pipe ring composed of an intake pipe and an exhaust pipe, when heating is required, hot air only needs to be introduced into the intake pipe.

[0019] A further technical solution is that an air inlet duct and an exhaust duct are also provided in the base plate, and the air inlet duct and the exhaust duct pass through the gap between the first mounting holes and are connected to the center of the annular casting area, and the air inlet duct and the exhaust duct are not connected to the first mounting holes, and the air inlet duct and the exhaust duct are located directly above the center of the annular casting area, and directly above the annular area between the inner wall and the outer wall, and are respectively provided with connecting grooves that are separately connected to each other, the connecting groove is located in the base plate, and a slot connected to the upper end surface of the base plate is opened at the top of the connecting groove, and a connecting head is inserted in the slot, and the two connecting heads at the center of the annular casting area are connected by a return bend pipe, the connecting head connecting to the air inlet duct in the annular area is connected to the air inlet pipe, and the connecting head connecting to the exhaust duct in the annular area is connected to the exhaust pipe.

[0020] A further technical solution is that a plurality of first threaded holes are provided at the top of the outer wall, and a second sliding hole that does not penetrate the bottom of the inner wall is correspondingly provided at the top of the inner wall. An outer connecting plate is also provided between the outer wall and the inner wall, and a through hole and a threaded hole are provided on the outer connecting plate. A first bolt is passed through the through hole of the outer connecting plate, and the first bolt is screwed in the first threaded hole. A second bolt is screwed in the threaded hole of the outer connecting plate, and an external thread is provided at the upper end of the second bolt, and no external thread is provided at the lower end of the second bolt, and the lower end of the second bolt is slidably inserted in the second sliding hole and the bottom of the second bolt abuts against the bottom of the second sliding hole.

[0021] By setting an outer connecting plate, the outer connecting plate is first fixedly installed on the outer wall with a first bolt, and then the second bolt is tightened to move downward relative to the outer connecting plate, and the bottom of the second bolt is pressed against the second sliding hole, so that the inner wall obtains downward pressure, so that the bottom of the inner wall is pressed against the upper end surface of the bottom plate.

[0022] A further technical solution is that at least two first through holes are provided on the bottom plate.

[0023] A method for using the above autoclaved concrete blocks to assemble a mold, the steps of which are as follows:

[0025] S2: placing the four right-angle walls at corresponding positions on the bottom plate, and using the third bolts and the inner connecting plate to cooperate with the third sliding holes and the empty first mounting holes to pre-fix the four right-angle walls on the bottom plate;

[0026] S3: Rotate the long strip plate to obtain a corresponding number of chain plates, and connect the four right-angle walls with four chain plates through the fourth bolt and the second threaded hole of the inner connecting plate to form a central wall;

[0030] The beneficial effects of the present invention are:

[0031] 1. By setting a center wall with adjustable length and width, the size of the hollow area of ​​the hollow concrete block can be adjusted according to demand, so that the production of hollow concrete blocks of different specifications can be completed without changing the mold. In addition, the four outer wall surfaces of the center wall are always smooth after the size changes, so that the inner wall of the cast hollow concrete block will not have ribs or grooves due to the size change of the center wall, avoiding the difficulty of demoulding due to the stuck ribs or grooves when the hollow concrete block is demoulded, and also ensuring the structural unity of the hollow concrete block product.

[0032] 2. By setting up the ventilation heating pipe ring, only the ventilation heating pipe ring needs to be heated during static maintenance. If necessary, a film can be covered on the top of the mold assembly to slow down heat loss. The ventilation heating pipe ring avoids heating the entire static room, thereby reducing the input of production energy.

[0033] 3. The inner side walls of the long strips are hinged together by setting hinges, so that the redundant long strips do not need to be disassembled. When forming the central wall, the redundant long strips are rotated to the inside of the central wall for storage, which improves the efficiency and convenience of switching the length of the chain plate.

[0034] 4. By setting the leveling bolts, the upper end surface of the bottom plate is made smooth to prevent leakage or bulges caused by concrete slurry being poured into the first mounting hole, which affects subsequent processing. By setting the elastic ring, an upward thrust can be provided to the first round rod to adjust the stretching degree of the first screw rod, so that the first screw rod is in a state that is not easy to rotate, and the first screw rod is prevented from rotating due to vibration during the movement of the mold assembly.

[0035] 5. By setting the air inlet and exhaust ducts, hot air can flow from the bottom plate into the return bend pipe located at the center of the annular casting area, thereby heating the return bend pipe, so that the center area of ​​the hollow concrete block can also be heated, thereby increasing the solidification speed. In addition, the structural design connected from the bottom of the annular casting area also ensures that the hollow concrete block will not be disturbed by the air inlet and exhaust pipes when demoulding.

[0036] 6. By setting up the air inlet pipe and the exhaust pipe, multiple modules can be used in series, so that the hot air can easily connect multiple modules to complete local heating. BRIEF DESCRIPTION OF THE DRAWINGS
