Description

Technical Field

[0001] The invention belongs to the technical field of rapid mold assembly, and in particular relates to a device for rapid on-site assembly of a prefabricated concrete part mold. Background Art

[0002] Stairs are components used for vertical transportation between floors in buildings. They are used for transportation between floors and when there is a large height difference. Although high-rise buildings use elevators as the main vertical transportation tool, they still need to retain stairs for escape in case of fire. Among them, stairs include components such as stair sections and platforms (resting platforms) of continuous steps. Usually, the cast-in-place reinforced concrete stairs used in housing construction projects are stair sections, platforms, ladder beams, etc. cast on site as a whole. They have good integrity, high rigidity, and strong earthquake resistance. However, during the construction process, a series of tedious processes such as installing rest platforms, installing ladder steps, welding, and grouting must be experienced. The construction efficiency is low, and it is very easy to have quality problems such as loose joints of concrete formwork, uneven step surfaces, missing corners and edges, and oversized dimensions, which bring a series of troubles to the subsequent decoration construction and acceptance.

[0003] Therefore, with the development of technology, prefabricated stairs dominated by steel molds have emerged. The stairs are prefabricated in a prefabrication factory or on-site, and then hoisted on-site to the stairwell. Prefabricated stairs are superior to cast-in-place stairs in terms of environmental protection, low carbon and finished product quality. However, prefabricated stairs dominated by steel molds are limited by the heavy weight of the steel molds. Both installation and disassembly require the assistance of mechanical equipment, and the installation efficiency is low. It is impossible to effectively realize the rapid connection between molds. Therefore, a concrete prefabricated mold on-site rapid assembly device is proposed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a device for quickly assembling a prefabricated concrete part mold on site that can overcome the above problems or at least partially solve the above problems.

[0005] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a rapid on-site assembly device for a concrete precast mold, including a first mold and a second mold. One end of the first mold is fixedly connected with a first end plate, and a bottom plate is fixedly connected to the first mold. One end of the second mold is fixedly connected with a second end plate, and further includes: a lower connecting block and an upper connecting block respectively arranged on the bottom surface and the surface of the second mold; a lower locking block and an upper locking block respectively detachably connected to the lower connecting block and the upper connecting block; a connecting component respectively arranged on the bottom plate; a locking component respectively arranged on the lower locking block and the upper locking block. When the second mold approaches the first mold, the locking component on the second mold engages with the connecting component to connect the first mold and the second mold; the connecting component is located between the first mold and the second mold. When the concrete precast part poured between the first mold and the second mold is taken out, the connecting component and the locking component are located inside the poured precast part.

[0006] Further, a plurality of lower fixing blocks and upper fixing blocks are respectively fixedly connected to the bottom surface and the surface of the second mold. The lower connecting block and the upper connecting block are respectively connected to the lower fixing block and the upper fixing block through a first bolt and a second bolt. Lower positioning columns and upper positioning columns are symmetrically and fixedly connected to the lower fixing block and the upper fixing block respectively. Lower positioning holes and upper positioning holes are symmetrically opened on the lower locking block and the upper locking block respectively. The lower locking block and the upper locking block are inserted onto the lower positioning column and the upper positioning column through interference fit of the lower positioning hole and the upper positioning hole.

[0007] Further, one end of the lower connecting block extends towards the second mold side, and a slot is opened on the bottom plate, and the lower connecting block corresponds to the slot.

[0008] Preferably, the connecting component includes a plurality of connecting rods inserted on the bottom plate. Both ends of each connecting rod are fixedly connected with a locking block. A jack is opened on the locking block at the lower end of the connecting rod. A plurality of pins are fixedly connected to the bottom plate. The connecting rod is inserted onto the pin on the bottom plate through interference fit of the jack. The connecting rod is connected to the inner wall of the first mold through a support rod.

[0009] Preferably, the connecting component includes a plurality of connecting rods inserted on the bottom plate. Both ends of each connecting rod are fixedly connected with a locking block. A jack is opened on the locking block at the lower end of the connecting rod. A plurality of pins are fixedly connected to the bottom plate. The connecting rod is inserted onto the pin on the bottom plate through interference fit of the jack. The connecting rod is connected to the inner wall of the first mold through a support rod; a transverse support beam is connected between the plurality of connecting rods. Extension beams are respectively connected to the connecting rods near both ends of the first mold. Clamping blocks are fixedly connected to one end of each extension beam and both ends of the transverse support beam for connecting with the connecting rods.

[0010] Preferably, the buckle assembly includes first connection grooves respectively formed in the lower locking block and the upper locking block. First sliding grooves and avoidance grooves are respectively formed on the front and back surfaces of the lower locking block, and a second sliding groove is formed on the bottom surface of the upper locking block. First side grooves are formed on both inner walls of the first connection groove, chamfer grooves are formed in the first side grooves, elastic steel sheets are fixedly connected in the first side grooves, and a first elastic abutting plate is fixedly connected to the bottom wall of the first connection groove. When the lower locking block and the upper locking block approach the locking block on the connecting rod, the locking block passes over the elastic steel sheet and enters the first connection groove between the first elastic abutting plate and the elastic steel sheet, realizing the buckling of the buckle assembly to the connecting rod.

[0011] Preferably, the buckle assembly includes second connection grooves respectively formed in the lower locking block and the upper locking block. First sliding grooves and avoidance grooves are respectively formed on the front and back surfaces of the lower locking block, and a second sliding groove is formed on the bottom surface of the upper locking block. Second side grooves are formed on both inner walls of the second connection groove. A side slider with a block at one end is slidably connected in the second side groove. The side slider is connected to the bottom wall of the second side groove through a spring, and a second elastic abutting plate is fixedly connected to the bottom wall of the second connection groove. When the lower locking block and the upper locking block approach the locking block on the connecting rod, the locking block passes over the side slider and enters the second connection groove between the second elastic abutting plate and the side slider, realizing the buckling of the buckle assembly to the connecting rod.

[0012] Preferably, it further includes symmetrically arranged tracks. A sliding seat is fixedly connected to the second mold, and the sliding seat is slidably connected to the tracks.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: By pushing the second mold closer to the first mold, the buckle assembly provided on the second mold buckles the connection assembly on the first mold, thereby realizing the rapid connection and assembly of the first mold and the second mold, enabling rapid operations such as pouring.

[0014] Moreover, this device can not only realize the rapid connection and assembly of the first mold and the second mold. The connection assembly provided therein can also form an integral body with the concrete precast member after concrete pouring. The connection assembly can span the width of the concrete precast member, enabling the connection assembly to act as a reinforcing rib in the concrete precast member, thereby improving the strength of the concrete precast member. The buckle assembly can be located on both sides of the width of the concrete precast member, and the buckle assembly is horizontal with the surfaces on both sides of the width of the concrete precast member staircase. Therefore, when assembling the concrete precast member staircase, the buckle assembly can also act as a connecting member, effectively expanding the application scope of this device.

[0015] Secondly, when the connecting component is located on the bottom plate of the first mold, when it is necessary to place the steel reinforcement cage between the first mold and the second mold, the connecting component can also play a positioning role, which can prevent the steel reinforcement cage from shifting during the pouring process, resulting in the problem of steel reinforcement cage exposure on the surface of the precast member after pouring, thereby effectively improving the pouring quality of the stair concrete precast member;

[0016] Moreover, the upper positioning holes and lower positioning holes on the upper locking block and lower locking block are exposed outside after the precast member is poured. Therefore, when installing the stair precast member, the lower positioning hole on the lower locking block can be used for positioning connection with the column embedded in the wall, and the upper positioning hole on the upper locking block can be used for positioning connection when installing the stair handrail.

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0035] The following will Figures 1 - 14 describe in detail the technical solutions provided by the embodiments of the present invention.

[0036] Embodiment 1: Referring to Figures 1 - 14 , a rapid on-site assembly device for concrete precast formwork, including a first formwork 1 and a second formwork 2. One end of the first formwork 1 is fixedly connected with a first end plate 11, and a bottom plate 12 is fixedly connected to the first formwork 1. One end of the second formwork 2 is fixedly connected with a second end plate 21. It further includes: a lower connecting block 221 and an upper connecting block 231 respectively arranged on the bottom surface and the surface of the second formwork 2; a lower locking block 224 and an upper locking block 234, which are respectively detachably connected to the lower connecting block 221 and the upper connecting block 231; a connecting component 400 respectively arranged on the bottom plate 12; a locking component 3 respectively arranged on the lower locking block 224 and the upper locking block 234. When the second formwork 2 approaches the first formwork 1, the locking component 3 on the second formwork 2 engages with the connecting component 400, so that the first formwork 1 and the second formwork 2 are connected; the connecting component 400 is located between the first formwork 1 and the second formwork 2. When the concrete precast member poured between the first formwork 1 and the second formwork 2 is taken out, the connecting component 400 and the locking component 3 are located inside the poured precast member; it further includes symmetrically arranged tracks 5, and a sliding seat 51 is fixedly connected to the second formwork 2, and the sliding seat 51 is slidably connected to the track 5;

[0037] When this device is in use, by pushing the second formwork 2 closer to the first formwork 1, the locking component 3 arranged on the second formwork 2 engages with the connecting component 400 on the first formwork 1, thereby realizing the rapid connection and assembly of the first formwork 1 and the second formwork 2, enabling rapid operations such as pouring;

[0038] Moreover, for the connecting component 400 in this device, after concrete pouring, the connecting component 400 and the locking component 3 can form an integral body with the concrete precast member, and the connecting component 400 can span the width of the concrete precast member, so that the connecting component 400 acts as a reinforcing bar in the concrete precast member, thereby improving the strength of the concrete precast member. The locking component 3 can be located on both sides of the width of the concrete precast member, and the locking component 3 is horizontal with the surfaces on both sides of the width of the concrete precast member staircase. Therefore, when assembling the concrete precast member staircase, the locking component 3 can also act as a connecting piece, effectively expanding the application range of this device;

[0039] Secondly, when the connecting component 400 is located on the bottom plate 12 of the first formwork 1, when it is necessary to place a steel reinforcement cage between the first formwork 1 and the second formwork 2, the connecting component 400 can also act as a positioning function, which can prevent the steel reinforcement cage from shifting during the pouring process, resulting in the problem of the steel reinforcement cage being exposed on the surface of the poured precast member, thereby effectively improving the pouring quality of the staircase concrete precast member.

[0040] Example 2: Refer to Figure 10 , Figure 11 , Figure 13 , Figure 14 , a rapid on-site assembly device for concrete precast molds, which is basically the same as Example 1. Further, a plurality of lower fixing blocks 22 and upper fixing blocks 23 are respectively fixedly connected to the bottom surface and the surface of the second mold 2. The lower connecting block 221 and the upper connecting block 231 are respectively connected to the lower fixing block 22 and the upper fixing block 23 through the first bolt 222 and the second bolt 232. Lower positioning columns 223 and upper positioning columns 233 are symmetrically and fixedly connected to the lower fixing block 22 and the upper fixing block 23 respectively. Lower positioning holes 225 and upper positioning holes 235 are symmetrically formed in the lower locking block 224 and the upper locking block 234 respectively. The lower locking block 224 and the upper locking block 234 are inserted into the lower positioning column 223 and the upper positioning column 233 through the lower positioning hole 225 and the upper positioning hole 235 by interference fit;

[0041] During use, by aligning the lower positioning hole 225 on the lower locking block 224 with the lower positioning column 223 on the lower connecting block 221, and the lower positioning column 223 is located on the upper surface of the lower connecting block 221. Therefore, the lower locking block 224 is inserted into the lower positioning column 223 through the lower positioning hole 225 by interference fit, enabling the lower locking block 224 to quickly complete the connection with the lower connecting block 221;

[0042] Similarly, the upper locking block 234 is also quickly installed on the upper connecting block 231 through the upper positioning hole 235 formed. The difference is that the upper positioning column 233 is located on the bottom surface of the upper connecting block 231, which makes the upper positioning column 233 and the lower positioning column 223 arranged relatively;

[0043] Since the locking components 3 are respectively arranged on the upper locking block 234 and the lower locking block 224, when the locking components 3 complete the locking connection with the connection components 400, the first mold 1 and the second mold 2 can be locked and connected. And when the concrete pouring is completed, by removing the upper connecting block 231 from the upper fixing block 23, and then using tools to create a gap between the first mold 1, the second mold 2 and the concrete precast. Subsequently, use the lifting equipment to lift the stair precast from above the first mold 1 and the second mold 2. The lower locking block 224 connected by insertion can automatically separate from the lower connecting block 221, realizing that the connection components 400, the locking components 3 and the stair precast form an integral body.

[0044] Example 3: Refer to Figure 3 , Figure 4 , Figure 5 , Figure 9, A rapid on-site assembly device for concrete precast molds, which is basically the same as Embodiment 2. Furthermore: One end of the lower connecting block 221 extends towards the second mold 2, and a slot 13 is provided on the bottom plate 12. The lower connecting block 221 corresponds to the slot 13;

[0045] When the second mold 2 approaches the first mold 1, one end of the lower connecting block 221 will enter the slot 13, filling the slot 13. At the same time, the lower locking block 224 will be located on the upper surface of the bottom plate 12, which enables the lower locking block 224 to be connected in the concrete precast during the solidification of the concrete;

[0046] The upper surface of the upper locking block 234 is horizontal with the upper surface of the second mold 2, which also enables the upper locking block 234 to be connected in the concrete precast during the solidification of the concrete;

[0047] Moreover, the upper positioning holes 235 and the lower positioning holes 225 on the upper locking block 234 and the lower locking block 224 are exposed outside after the precast is poured. Therefore, when installing the stair precast, it is convenient to use the upper positioning holes 235 and the lower positioning holes 225 to install and connect the stair precast.

[0048] Embodiment 4: Refer to Figure 3 , A rapid on-site assembly device for concrete precast molds, which is basically the same as Embodiment 3. Furthermore: The connecting component 400 includes multiple connecting rods 41 inserted on the bottom plate 12. Both ends of the connecting rod 41 are fixedly connected with locking blocks 4. A jack 40 is provided on the locking block 4 at the lower end of the connecting rod 41. Multiple pins are fixedly connected to the bottom plate 12. The connecting rod 41 is inserted on the pins on the bottom plate 12 through interference fit of the jack 40. The connecting rod 41 is connected to the inner wall of the first mold 1 through a support rod 42;

[0049] When installing the connecting component 400, the locking block 4 with the jack 40 is aligned with the pins on the bottom plate 12 to connect the connecting rod 41 to the bottom plate 12;

[0050] When it is necessary to place the steel reinforcement cage between the first mold 1 and the second mold 2, first place the steel reinforcement cage, then connect the support rod 42 to the connecting rod 41 and make one end of the support rod 42 abut against the inner wall of the first mold 1, which makes the connecting rod 41 more stable;

[0051] At the same time, multiple connecting rods 41 and support rods 42 are located in the solidified concrete precast, which can further enhance the strength of the stair precast.

[0052] Embodiment 5: Refer to Figure 5 、 Figure 6 、 Figure 7, A rapid on-site assembly device for concrete precast formwork, which is basically the same as Embodiment 3. Further: The connection assembly 400 includes multiple connecting rods 41 inserted into the bottom plate 12. Both ends of the connecting rod 41 are fixedly connected with locking blocks 4. A jack 40 is opened on the locking block 4 at the lower end of the connecting rod 41. Multiple pins are fixedly connected to the bottom plate 12. The connecting rod 41 is inserted onto the pins on the bottom plate 12 through interference fit of the jack 40. The connecting rod 41 is connected to the inner wall of the first formwork 1 through a support rod 42; A transverse support beam 43 is connected between multiple connecting rods 41. Extension beams 44 are respectively connected to the connecting rods 41 near both ends of the first formwork 1. Clamping blocks 6 are fixedly connected to one end of the extension beam 44 and both ends of the transverse support beam 43 for connection with the connecting rod 41;

[0053] When installing the connection assembly 400, the connecting rod 41 is connected to the bottom plate 12 by aligning the locking block 4 with the jack 40 with the pin on the bottom plate 12;

[0054] Then, the support rod 42 and the transverse support beam 43 are installed on the connecting rod 41 one by one, so that multiple horizontal and vertical staggered reinforcing ribs are formed between the first formwork 1 and the second formwork 2 by the connection assembly 400. The steel reinforcement cage can be dispensed with, further improving the assembly efficiency of the first formwork 1 and the second formwork 2.

[0055] Embodiment 6: Refer to Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 , A rapid on-site assembly device for concrete precast formwork, which is basically the same as Embodiments 4 and 5. Further: The lock assembly 3 includes first connection grooves 227 respectively opened in the lower locking block 224 and the upper locking block 234. First sliding grooves 228 and avoidance grooves 226 are respectively opened on the front and back surfaces of the lower locking block 224. The avoidance groove 226 is used to avoid the pins on the bottom plate 12. A second sliding groove 238 is opened on the bottom surface of the upper locking block 234. First side grooves 31 are opened on both inner walls of the first connection groove 227. A chamfer groove 32 is opened on the first side groove 31. An elastic steel sheet 33 is fixedly connected in the first side groove 31. A first elastic abutting plate 34 is fixedly connected to the bottom wall of the first connection groove 227. When the lower locking block 224 and the upper locking block 234 approach the locking block 4 on the connecting rod 41, the locking block 4 crosses the elastic steel sheet 33 and enters the first connection groove 227 between the first elastic abutting plate 34 and the elastic steel sheet 33, realizing the locking of the lock assembly 3 to the connecting rod 41;

[0056] When the first mold 1 approaches the second mold 2, the locking blocks 4 at both ends of the connecting rod 41 will enter the first connecting grooves 227 of the lower locking block 224 and the upper locking block 234 respectively, and the locking blocks 4 will squeeze the elastic steel sheet 33 and pass over the elastic steel sheet 33, and the locking blocks 4 will bite into the first connecting grooves 227 through the first elastic contact plate 34, thereby realizing the connection between the first mold 1 and the second mold 2;

[0057] When the locking block 4 passes over the elastic steel sheet 33, since the chamfered groove 32 is provided on the first side groove 31, the elastic steel sheet 33 has a bending space. When the locking block 4 is located between the first elastic resistance plate 34 and the elastic steel sheet 33, the side wall of the first side groove 31 and the chamfered groove 32 corresponding to the first connecting groove 227 is perpendicular to the first connecting groove 227, thereby preventing the locking block 4 from detaching from the first connecting groove 227, thereby realizing the bite connection between the locking assembly 3 and the connecting assembly 400.

[0058] Example 7: Reference Figure 10 , Figure 11 , Figure 12 , Figure 14 , a concrete prefabricated part mold on-site rapid assembly device, which is basically the same as embodiments 4 and 5, and further, the locking assembly 3 includes a second connecting groove 237 respectively opened in the lower locking block 224 and the upper locking block 234, the front and back surfaces of the lower locking block 224 are respectively provided with a first slide groove 228 and an avoidance groove 226, the bottom surface of the upper locking block 234 is provided with a second slide groove 238, and the inner walls on both sides of the second connecting groove 237 are provided with second side grooves 311, the second side grooves 311, and the second side grooves 311. 1 is slidably connected to a side slider 312 with a clamping block 313 at one end, the side slider 312 is connected to the bottom wall of the second side groove 311 through a spring 314, and a second elastic contact plate 315 is fixedly connected to the bottom wall of the second connecting groove 237. When the lower locking block 224 and the upper locking block 234 approach the locking block 4 on the connecting rod 41, the locking block 4 passes over the side slider 312 and enters the second connecting groove 237 between the second elastic contact plate 315 and the side slider 312, so that the locking assembly 3 bites the connecting rod 41;

[0059] When the first mold 1 approaches the second mold 2, the locking blocks 4 at both ends of the connecting rod 41 will enter the second connecting grooves 237 of the lower locking block 224 and the upper locking block 234 respectively, and the locking blocks 4 will push the side sliders 312 to slide into the second side grooves 311 and squeeze the springs 314, and then the locking blocks 4 will pass over the symmetrically arranged side sliders 312, so that the locking blocks 4 are located between the second elastic contact plates 315 and the side sliders 312;

[0060] Since the side slide block 312 is arranged in the second side groove 311 for tilted sliding, the locking block 4 is difficult to be separated from the second connection groove 237, so that the first mold 1 and the second mold 2 can be connected more stably;

[0061] It should be noted that the end of the side slider 312 is limited and slides in the second side groove 311 through the clamping block 313.

[0062] Therefore, the connecting component 400 in the present invention can, after concrete pouring, form an integral body with the connecting component 400 and the locking component 3 and the concrete precast member. The connecting component 400 can span the width of the concrete precast member, so that the connecting component 400 acts as a reinforcing bar in the concrete precast member, thereby improving the strength of the concrete precast member. The locking component 3 can be located on both sides of the width of the concrete precast member, and the locking component 3 is horizontal with the surfaces on both sides of the width of the concrete precast member staircase. Therefore, when assembling the concrete precast member staircase, the locking component 3 can also be used as a connecting piece, thereby effectively expanding the application range of the present device;

[0063] Secondly, when the connecting component 400 is located on the bottom plate 12 of the first mold 1, when it is necessary to place the steel reinforcement cage between the first mold 1 and the second mold 2, the connecting component 400 can also act as a positioning function, which can prevent the steel reinforcement cage from shifting during the pouring process, resulting in the problem of the steel reinforcement cage being exposed on the surface of the precast member after pouring, thereby effectively improving the pouring quality of the staircase concrete precast member;

[0064] Moreover, the upper positioning holes 235 and the lower positioning holes 225 on the upper locking block 234 and the lower locking block 224 are exposed outside after the precast member is poured. Therefore, when installing the staircase precast member, the lower positioning hole 225 on the lower locking block 224 can be used for positioning and connecting with the column embedded in the wall, and the upper positioning hole 235 on the upper locking block 234 can be used for positioning and connecting when installing the staircase handrail.

[0065] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content to make equivalent embodiments of equivalent changes without departing from the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
