Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated buildings, in particular to an external elevator assembly type building system and balcony application mold. BACKGROUND

[0002] With the continuous intensification of population aging in China, some old communities have not configured elevators, leading to difficulties in daily travel for residents. In order to solve the problem of daily travel for residents in old communities, the government vigorously advocates old city reconstruction and installation of elevator shafts. At present, there are two ways to install elevator shafts, traditional cast-in-place construction and steel structure glass curtain wall. If reinforced concrete elevator shafts are used by traditional cast-in-place, it is necessary to erect and disassemble supports layer by layer, which has a long construction period and produces a lot of construction dust and noise, seriously disturbing the residents. If steel structure glass curtain wall elevator shafts are used, although the construction period is short and the construction noise is small, the steel structure is prone to rust and has poor fire resistance, and needs to be treated for corrosion and fire resistance every few years, which has high maintenance cost in the later period. In addition, during the transportation of the elevator box, vibration load is generated on the steel structure, and the vibration noise is large.

[0003] With the continuous development of construction engineering, prefabricated assembly type buildings are widely used in various construction fields, that is, only assembly and connection are needed on site, without additional formwork and concrete pouring. This assembly type construction form can shorten the construction period, reduce the waste of construction materials, save manpower and resources, and save resources. However, for the installation of elevators in old community reconstruction, the width of the balcony in old communities is not standardized, and the existing prefabricated assembly type balcony is produced separately by using a variety of prefabricated parts, which has a complex process and cannot be accurately connected between the elevator shaft and the building. This results in a complicated construction process, non-standardized operation, and a prolonged construction period. Especially during the standard quantitative production in the factory, the mold has poor adjustability and cannot be quickly adjusted according to the width of the balcony in the old community, resulting in poor universality and inaccurate installation matching of the beam column of the elevator shaft in the later period. Moreover, in order to ensure suitable temperature and reduce noise in the elevator shaft, the existing prefabricated elevator shaft is made of full concrete prefabrication, which makes the single section shaft too heavy, greatly increasing the hoisting difficulty and the cost of prefabrication. When the single section shaft is intentionally lightened by means of hole opening, etc., the internal heat preservation effect of the elevator shaft is not achieved, the influence of external cold and heat is large, the equipment operation is affected, and the use effect is affected when the elevator equipment operates, which is not conducive to the promotion of external elevators. SUMMARY

[0026] The side mold assembly comprises two end molds arranged oppositely, and two side molds connected between the two sides of the two end molds;

[0027] The two end molds and the two side molds form a rectangular pouring space around the first bottom mold and the second bottom mold, the first bottom mold and the second bottom mold are spaced apart inside the pouring space, and the first bottom mold and the second bottom mold separate the bottom of the pouring space into two parallel transverse settlement channels and two parallel longitudinal settlement channels;

DETAILED DESCRIPTION

[0049] In order to make the objects, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to specific embodiments and drawings.

[0050] It should be noted that, unless otherwise defined, technical terms or scientific terms used in one or more embodiments of the present disclosure should be understood as their common meanings to those skilled in the art to which the present disclosure pertains. The terms "first", "second" and similar terms used in one or more embodiments of the present disclosure do not represent any order, quantity or importance, but are only used to distinguish different components. The terms "include", "contain" and similar terms mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, and do not exclude other elements or objects. The terms "connect" or "connected" and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms "upper", "lower", "left", "right" and the like are only used to represent relative positional relationships, and when the absolute positions of the described objects change, the relative positional relationships may also change accordingly.

[0051] In order to facilitate the understanding of the assembly type building system and balcony application mold of the external elevator provided by the embodiments of the present application, the application scene thereof is first described. With the continuous development of building engineering, prefabricated assembly type buildings are widely used in various building fields, that is, only assembly and splicing are needed on site, and no additional formwork pouring of concrete is needed. This assembly type building construction form can shorten the construction period, reduce the waste of building construction materials, save manpower and resources, and save resources. However, when installing an elevator in an old community, the width of the balcony in the old community is not standardized, the existing prefabricated assembly type balcony is produced separately by using a plurality of different prefabricated parts, the process is relatively complex, and the prefabricated parts cannot be accurately connected between the elevator shaft and the building. This results in a complicated construction process, non-uniform standardized operation, and a prolonged construction period. In particular, during the process of standard quantitative production in the factory, the mold has poor adjustability and cannot be quickly adjusted according to the width of the balcony in the old community, which results in poor universality and inaccurate installation matching of the beam column of the elevator shaft in the later period. Moreover, in order to ensure that the temperature in the elevator shaft is suitable and reduce noise, the prefabricated elevator shaft is made of full concrete, which results in an over-heavy single-section shaft, greatly increasing the hoisting difficulty and the cost of prefabrication. When the single-section shaft is intentionally lightened by means of hole opening and the like, the internal part of the elevator shaft does not have a heat preservation effect, is greatly affected by external cold and heat, affects the operation of the equipment, and causes a large amount of noise to be leaked during the operation of the elevator equipment, which affects the use effect and is not conducive to the promotion of the external elevator. In view of this, the present application provides an assembly type building system and balcony application mold of an external elevator, which ensures high efficiency and convenience during assembly, reduces cast-in-place operation, and has firm and reliable connection reliability. At the same time, the elevator shaft module is lightened, heat-preserved, and sound-insulated, which reduces the hoisting difficulty and improves the use effect of the external elevator.

[0052] Reference Figure 1 The assembly type building system of the external elevator provided by the embodiments of the present application comprises a plurality of layers of full prefabricated balconies which are sequentially stacked and arranged along the outer side of the building body. The plurality of layers of full prefabricated balconies are matched with the floors of the building body. The existing building layers in old communities are five or six layers, and the like. Two ways of traditional cast-in-place construction and steel structure glass curtain wall are used. If a reinforced concrete elevator shaft is used in the traditional cast-in-place construction, the construction period is long, and the construction dust and noise are large, which seriously disturb the residents. If a steel structure glass curtain wall elevator shaft is used, the construction period is short, and the construction noise is small, but the steel structure is prone to rust, and the fire resistance is poor, so that the anti-corrosion and fireproofing treatment needs to be performed every few years, and the later maintenance cost is high. In addition, during the transportation of the elevator box, vibration load is generated on the steel structure, and the vibration noise is large. In the embodiments of the present application, the full prefabricated balcony of the concrete component is used, the installation standard is unified, the construction period is shortened, the vibration noise is reduced, the later operation and maintenance cost is reduced, a higher building system standard is provided for the external elevator, and the promotion and application of the external elevator are facilitated.

[0053] Each full-precast balcony in the embodiments of the present application comprises: a plurality of support beam columns 100, and a precast balcony plate 200 horizontally assembled on the top of the plurality of support beam columns 100; the plurality of support beam columns 100 are prepared in a factory-precast manner, and are combined in a form of reinforced concrete to become the support beam columns 100, and both ends of each support beam column 100 are provided with an extension bar 110 extending into the inside of a corresponding beam-column connecting node 240. The extension bar 110 is used to connect the precast balcony plates 200 of the upper and lower layers.

[0054] Each full-precast balcony supports the precast balcony plate 200 by the plurality of support beam columns 100. In the embodiments of the present application, it is preferred that four support beam columns 100 support one precast balcony plate 200, so as to ensure the effect of stable support. Each full-precast balcony can include two precast balcony plates 200 for transverse splicing. Of course, three or four precast balcony plates 200 can also be used for different building structures. When constructing the full-precast balcony of multiple layers, the foundation base is constructed, the support beam columns 100 are installed on the foundation base, and the precast balcony plate 200 is installed on the top of the support beam column 100; when the full-precast balcony of the bottom layer is built, the support beam column 100 is installed on the precast balcony plate 200, and the precast balcony plate 200 of the upper layer is installed on the support beam column 100, and the like, so as to realize the standardized operation, shorten the construction period, and generate less dust and noise in the construction process, and the operation process is simple and convenient. The precast balcony plate 200 is provided with an extension lap joint portion 210 on the side facing the building structure, and the extension lap joint portion 210 can be perfectly connected with the building structure, so as to ensure the stability of the connection.

[0055] In combination with the description shown in Figure 3 In order to ensure the connection stability of the support beam column 100 and the precast balcony plate 200, the beam-column connecting node 240 corresponding to the plurality of support beam columns 100 is provided on the balcony precast plate; the steel bars are longitudinally and transversely staggered in the inside of the beam-column connecting node 240, and the two support beam columns 100 in the same vertical direction and adjacent to each other are connected to the steel bars of the same beam-column connecting node 240. Specifically, the bottom of the precast balcony plate 200 is provided with the transverse reinforcing bar 220 and the longitudinal reinforcing bar 230 in parallel; the transverse steel bars 250 of the transverse reinforcing bar 220 and the longitudinal steel bars 260 of the longitudinal reinforcing bar 230 extend to the plurality of beam-column connecting nodes 240. When the transverse steel bars 250 and the longitudinal steel bars 260 increase the strength of the precast balcony plate 200, the transverse steel bars 250 and the longitudinal steel bars 260 ensure the connection strength with the support beam column 100.

[0056] When two support beam columns 100 in the same vertical direction and adjacent to each other are connected to the same reinforcing steel bars of the beam-column joint 240, the extension bars 110 at the top of the lower support beam column 100 are connected to the transverse steel bars 250 and the longitudinal steel bars 260 and then cast-in-situ concrete is poured; the extension bars 110 at the bottom of the upper support beam column 100 are connected to the transverse steel bars 250 and the longitudinal steel bars 260 and then cast-in-situ concrete is poured. Through the beam-column joint 240, the cast-in-situ area is reduced, the standardized assembly is ensured, and the construction period is shortened. In the above manner, the balcony is fully prefabricated from the bottom layer to the upper layer in turn, the prefabricated balcony slab 200 is connected to the building body through the extension lap 210, the cast-in-situ composite layer is cancelled, and only a small amount of cast-in-situ operation is performed at the beam-column joint 240, thereby ensuring the overall stability. The prefabricated structural members include the support beam column 100 and the prefabricated balcony slab 200, which are split through standardized design and are fully prefabricated in a standard size to speed up the construction process. The fully prefabricated balcony has a complete structure and does not rely on the elevator shaft and the building body for bearing, thereby realizing independent force bearing.

[0057] Referring to Figure 2 and Figure 4 shown in the drawings, the prefabricated elevator shaft is made of full concrete to ensure that the temperature in the shaft is suitable and the noise is reduced, which results in that the single-section shaft is too heavy, greatly increasing the hoisting difficulty and the prefabricated cost; when the single-section shaft is deliberately lightened through hole opening and the like, the internal part of the elevator shaft does not have a heat preservation effect and is greatly affected by the external cold and heat, which affects the equipment operation, the noise generated during the operation of the elevator equipment is discharged, which affects the use effect, and the external elevator is not conducive to popularization. Therefore, the multi-layer fully prefabricated balcony is connected to the lightened elevator shaft in the present application. The lightened elevator shaft has the effects of lightening, heat preservation, and sound insulation, reduces the hoisting cost and difficulty, and reduces the noise generated during the operation of the elevator equipment, thereby having good application effect. The lightened elevator shaft comprises: a plurality of elevator shaft modules 300 arranged in the height direction of the multi-layer fully prefabricated balcony in turn; each elevator shaft module 300 corresponds to the prefabricated balcony of the same layer, and the multi-layer elevator shaft modules 300 are built in turn from the bottom layer and are connected to the multi-layer fully prefabricated balcony.

[0058] Each elevator shaft module 300 comprises a prefabricated frame and an assembled lightened wall 330 mounted on the circumferential side wall of the prefabricated frame; the prefabricated frame comprises: support columns 320 distributed in a rectangular manner and an elevator shaft ring beam 310 connected to the top of the support columns 320; the support columns 320 and the elevator shaft ring beam 310 are also integrally cast and formed by factory prefabrication. The assembled lightened wall 330 is connected between any two adjacent support columns 320. Through the installation of the assembled lightened wall 330, a high lightening effect is ensured, and the hoisting operation difficulty is reduced.

[0059] AsFigure 4 As shown, a coordinate system is established in the elevator shaft module 300. The Z-direction of this coordinate system represents the length of the elevator shaft module 300, the X-direction represents the width of the elevator shaft module 300, and the Y-direction represents the height of the elevator shaft module 300. Furthermore, the Z-direction in this application is perpendicular to both the X and Y directions. This coordinate system illustrates the assembly method of the elevator shaft module 300.

[0060] Multiple elevator shaft modules 300 are sequentially overlapped along the Y direction. Adjacent elevator shaft modules 300 are connected by pre-embedded steel bars. Each elevator shaft module 300 has an elevator opening 340 reserved on the same floor of the fully prefabricated balcony. Each prefabricated frame is fixedly connected to the corresponding support beam and column 100 by multiple pre-embedded steel plate connectors 400, thereby enhancing the connection strength of the overall weight-reducing elevator shaft.

[0061] The prefabricated weight-reducing wall 330 comprises an outer prefabricated wall 350 for sound insulation and weight reduction, an inner prefabricated wall 360, and a filling layer 380 located between the outer prefabricated wall 350 and the inner prefabricated wall 360; the filling layer 380 is EPS insulation board and / or polyurethane foam. By using EPS insulation board and polyurethane foam as the filling layer 380, it achieves high-performance thermal insulation and sound insulation.

[0062] The prefabricated weight-reducing wall 330 also has a keel frame 370 connected between any two adjacent support columns 320. The outer prefabricated wall 350 and the inner prefabricated wall 360 are fixedly connected to the keel frame 370 by self-tapping screw assemblies 390. Through the assembly and fixing of the keel frame 370, the connection performance between the outer prefabricated wall 350 and the inner prefabricated wall 360 is stable.

[0063] Combination Figure 5 and Figure 6 As shown, both the outer and inner prefabricated walls are assembled sequentially from composite panels with polystyrene particle concrete layers 361 and cement fiber layers 362. The polystyrene particle concrete layers 361 of the outer and inner prefabricated walls face each other, while the cement fiber layers 362 of the outer and inner prefabricated walls face away from each other. This design reduces the weight of the elevator shaft module 300 while maintaining high-performance thermal insulation and soundproofing. It allows for prefabrication and assembly of elevator shafts of different sizes, offering strong flexibility, reducing manufacturing costs, and decreasing hoisting costs and safety after weight reduction.

[0064] When specifically installing the prefabricated weight-reducing wall 330, combined with Figure 4As can be seen from the coordinate system in the figure, the support column 320 is integrally cast with the elevator shaft ring beam 310. The integrally cast wall is reduced, thereby greatly reducing the weight of the prefabricated elevator shaft module 300, which can be controlled at about 4T, thereby greatly reducing the prefabrication cost and reducing the hoisting cost, and improving the hoisting safety.

[0065] The assembled weight-reducing wall 330 is fixedly assembled between any transversely and longitudinally adjacent support columns 320. Two assembled weight-reducing walls 330 are installed in the Z direction, two assembled weight-reducing walls 330 are installed in the X direction, and an elevator port 340 is formed on one assembled weight-reducing wall 330 in the X direction. The elevator port 340 can be formed in different ways according to the welding structure of the keel frame 370 and the preparation of different sizes of prefabricated wall panels. In other embodiments of the present application, the keel frame can also be fixed to the four sides of the prefabricated frame by means of nailing, expansion bolts, etc.

[0066] The four assembled weight-reducing walls 330 realize the four sides of the prefabricated frame, thereby replacing the integrally cast wall. The assembled weight-reducing wall 330 greatly reduces the weight of the elevator shaft while having higher heat preservation and sound insulation effects. The keel frame 370 is made of common building materials such as C-shaped steel or square tube, and is arranged in the space between the two support columns 320 after cutting and welding. The overall installation process is simple and has high flexibility. The keel frame 370 is connected between any two adjacent support columns 320 by anchor pieces and / or expansion bolts. The inner and outer prefabricated wall panels are fixedly connected to the keel frame 370 by self-tapping screw assemblies 390. For example, the thickness of the assembled weight-reducing wall 330 in the present application is between 100mm and 200mm. The optional specifications are diversified and suitable for different application scenarios. When the thickness of the assembled weight-reducing wall 330 is 200mm, the thickness of the inner and outer prefabricated walls 360 and 350 is 50mm respectively, and the thickness of the thermal insulation layer is 100mm.

[0067] The keel frame 370 is welded between the two adjacent support columns 320, and the space of the elevator port 340 is reserved. After the keel frame 370 is welded, the prefabricated wall is installed on the outer side of the keel frame 370 or on the inner side of the keel frame 370 in advance. Either the inner side or the outer side can be installed in advance. For example, the outer prefabricated wall 350 is installed on the outer side of the keel frame 370 in advance. After the outer prefabricated wall 350 is installed, the thermal insulation layer is filled in the keel frame 370. The thermal insulation layer is embedded in the keel frame 370, and then the inner prefabricated wall 360 is installed. Foamed polyurethane is filled in the gap between the outer prefabricated wall 350 and the inner prefabricated wall 360 and the thermal insulation layer.

[0068] The outer prefabricated wall 350 and the inner prefabricated wall 360 in the application are both assembled by combined panels with a polystyrene particle concrete layer 361 and a cement fiber layer 362; after assembly, the adjacent two combined panels are sealed by tile glue 391, and at the same time, in order to prevent cracking, a layer of glass fiber mesh is laid at the joint of the two combined panels during decoration.

[0069] For example, the combined panel includes an inner polystyrene particle concrete layer 361 and an outer cement fiber layer 362; the cement fiber layer 362 is connected to the outer surface of the polystyrene particle concrete layer 361 in a staggered manner, and the cement fiber layer 362 has a lap joint and a snap joint at both ends of the polystyrene particle concrete layer 361, so as to facilitate seamless joint connection between the two adjacent combined panels. The prefabricated light-weight wall 330 in the application has the effects of reducing weight, improving thermal insulation and sound insulation, and the outer cement fiber layer 362 has good fireproof effect. The outer prefabricated wall and the inner prefabricated wall have the same prefabricated form, and the outer prefabricated wall and the inner prefabricated wall are in a relative assembly relationship, that is, the polystyrene particle concrete layer 361 of the outer prefabricated wall and the polystyrene particle concrete layer 361 of the inner prefabricated wall face each other, and the cement fiber layer 362 of the outer prefabricated wall and the cement fiber layer 362 of the inner prefabricated wall face away from each other, so that the cement fiber layer 362 is located on the inner and outer surfaces, and the high-density cement fiber layer 362 has good fireproof performance.

[0070] Between any two adjacent combined panels on the same assembly surface, the lap joint connection is formed by the snap joint of one combined panel snapping the lap joint of the other combined panel. The assembly method is simple and convenient, and the outer surface is flat and beautiful. After assembly, the adjacent two combined panels are sealed by tile glue 391, and at the same time, in order to prevent cracking, a layer of glass fiber mesh is laid at the joint of the two combined panels during decoration.

[0071] In the application, the beam-column connecting node 240 is provided on the prefabricated balcony panel 200 to ensure the stability of the support connection between the support beam column 100 and the prefabricated balcony panel 200, reduce the cast-in-place area, shorten the construction period by standardized operation, and firmly and reliably connect. At the same time, the building system effectively reduces the overall weight of the elevator shaft module 300 by the prefabricated light-weight wall 330, which is convenient for hoisting; the combination of the outer prefabricated wall 350, the inner prefabricated wall 360 and the middle filling layer 380 has high efficient thermal insulation and sound insulation effects, improves the use effect of the external elevator, and reduces the later operation and maintenance cost.

[0072] In combination with Figure 7 And Figure 8The application also provides a balcony application mold 500, which comprises the balcony application mold 500 for prefabricating the prefabricated balcony plate 200; the balcony application mold 500 comprises a bottom mold assembly, a side mold assembly and four column molds 570 arranged on a mold table.

[0073] The side mold assembly is arranged on the mold table in the application, surrounds a rectangular pouring space, the bottom mold assembly is arranged in the side mold assembly, and the four column molds 570 are connected between the side mold assembly and the bottom mold assembly. In the embodiment of the application, the embedded bolt, the first bolt assembly or the second bolt assembly are all connected by M16 bolts matched with nuts, so that the side mold assembly, the bottom mold assembly and the four column molds 570 are all detachably connected, which is convenient for flexible adjustment and has strong versatility.

[0074] Specifically, the side mold assembly is detachably connected to the periphery of the bottom mold assembly. Meanwhile, the bottom mold assembly in the application comprises a split first bottom mold 510 and a second bottom mold 520. By adjusting the positions of the first bottom mold 510 and the second bottom mold 520, the horizontal reinforcing bars 220 and the vertical reinforcing bars 230 of the prefabricated balcony plate 200 are poured, and when prefabricating prefabricated balcony plates 200 of different lengths, the first bottom mold 510 and the second mold plate of different lengths can be replaced.

[0075] The side mold assembly comprises two end molds arranged oppositely and two side molds connected between the two sides of the two end molds; wherein the two side molds and the two end molds are all perpendicularly assembled. The assembly is more modular. It should be understood that the two end molds and the two side molds form a rectangular pouring space around the first bottom mold 510 and the second bottom mold 520, the first bottom mold 510 and the second bottom mold 520 are arranged in the interior of the pouring space, and the first bottom mold 510 and the second bottom mold 520 isolate the bottom of the pouring space into two parallel horizontal settlement grooves and two parallel vertical settlement grooves. The two parallel horizontal settlement grooves form the horizontal reinforcing bars 220 of the prefabricated balcony plate 200 after the reinforced concrete is demolded, and the two parallel vertical settlement grooves form the vertical reinforcing bars 230 of the prefabricated balcony plate 200 after the reinforced concrete is demolded.

[0076] The heights of the two end molds and the two side molds are greater than the heights of the first bottom mold 510 and the second bottom mold 520, so that the plane of the prefabricated balcony plate 200 is formed after pouring concrete in the pouring space.

[0077] And, after the two transverse settlement tank and two longitudinal settlement tank are arranged with steel bars, the concrete is cast in place, thereby forming the transverse reinforcing bars 220 and the longitudinal reinforcing bars 230 of the prefabricated balcony slab 200. Meanwhile, in the embodiment of the present application, in order to realize high-strength connection between the prefabricated balcony slab 200 and the support beam column 100, four column molds 570 are respectively arranged at the intersections of the two transverse settlement tanks and the two longitudinal settlement tanks, and a plurality of through-bar holes 571 are symmetrically arranged on any two opposite walls of each column mold 570. After the prefabricated balcony slab 200 is demolded, the four column molds 570 form beam-column connection nodes 240, and the transverse steel bars 250 and the longitudinal steel bars 260 are located inside the beam-column connection nodes 240 through the through-bar holes 571, thereby being better connected with the extension bars 110 of the beam column.

[0078] When the mold is flexibly adjusted according to balconies with different widths, the length of one side mold and / or two side molds in the embodiment of the present application can be assembled and adjusted. Thus, single-sided adjustment or double-sided adjustment can be realized. Specifically, the two end molds are a first end mold 530 and a second end mold 540; one end of the first bottom mold 510 away from the second bottom mold 520 is connected with the first end mold 530 through a pre-buried bolt; and the second end mold 540 is located at one end of the second bottom mold 520 away from the first bottom mold 510. The first end mold 530 and the second end mold 540 are distributed in a relative arrangement, and the first end mold 530 is connected with the first bottom mold 510 through a pre-buried bolt, which is more convenient to disassemble and assemble. The width of the first bottom mold 510 is the same as the width of the second bottom mold 520, and the length of the first bottom mold 510 is less than the length of the second bottom mold 520, thereby ensuring that, after one prefabricated balcony slab 200 is connected with the support beam column 100, the casting area above the first bottom mold 510 can be overlapped with another prefabricated balcony slab 200.

[0079] In combination with Figure 8As shown in the drawings, in the embodiment of the present application, the length of one side mold is preferably adjustable by assembly, and the length of the other side mold is fixed. Of course, in other embodiments of the present application, the lengths of both side molds can be adjusted by assembly. For example, when the length of one side mold is adjustable by assembly: the two side molds include a first side mold 550 and a second side mold 560; the first side mold 550 is connected to the first end mold 530 and the second end mold 540 by the same first side bolt, and the length of the first side mold 550 is greater than the maximum distance between the first end mold 530 and the second end mold 540; the length of the first side mold 550 is fixed and greater than the maximum length of the first end mold 530 and the second end mold 540. For example, when the length of the prefabricated balcony plate 200 is prepared to be between 4.5m and 6m, the length of the first side mold 550 is 6m, and the distance between the first end mold 530 and the second end mold 540 is adjusted to be between 4.5m and 6m. The first side mold 550 includes three first side mold plates 551 with a length of 2m, which are combined and connected. Any two adjacent first side mold plates 551 are connected and fixed by a first bolt assembly. Thus, the disassembly and assembly are more convenient. After the first side mold 550 meets the maximum length requirement, the lengths of the first end mold 530 and the second end mold 540 are adjusted according to the prefabrication requirement, and then the first side mold 550 is connected and fixed to the first end mold 530 and the second end mold 540 by the bolt assembly, and then the length of the second side mold 560 is adjusted according to the length requirement.

[0080] Specifically, the second side mold 560 is connected to the first end mold 530 and the second end mold 540 by the same second side bolt, and the length of the second side mold 560 can be assembled with the same length corresponding to the adjusted distance between the first end mold 530 and the second end mold 540. The second side mold 560 has a plurality of second side mold plates 561 with the same length and a plurality of adjustment plates 562 with different lengths; any two adjacent second side mold plates 561 or any adjacent second side mold plate 561 and the corresponding adjustment plate 562 are connected and fixed by a second bolt assembly. By assembling the second side mold 560 with different lengths of the adjustment plate 562, flexible size adjustment can be achieved. For example, if a 5m long prefabricated balcony plate 200 is required, the standard length of the second side mold plate 561 is 2m, and at this time, the adjustment plate 562 with a length of 1m is selected, so that two second side mold plates 561 and one adjustment plate 562 are combined to form the second side mold 560, and the two ends of the second side mold 560 are connected and fixed to the first end mold 530 and the second end mold 540 by the bolt assembly.

[0081] Furthermore, any one of the second side mold plates 561 and any one of the adjustment plates 562 has the same size of the extension lap convex mold 563. The extension lap part 210 formed by the prefabricated balcony is more stable when connected to the building.

[0082] In the specific distribution column die 570, four column dies 570 are respectively located at the four corners of the second bottom die 520; and the four column dies 570 are respectively in contact with the second end die 540, the first side die plate 551 and the second side die plate 561, and the four corners of the second bottom die 520 are each provided with an L-shaped groove 521 corresponding to the four column dies 570. The matching degree of the limit is higher.

[0083] Moreover, each column die 570 is a rectangular solid column, and the inside of each column die 570 has a beam-column connection node 240 space matched with the support beam column 100. The precast process is reduced, the beam-column connection node 240 space is reserved, and the construction process is accelerated. The height of each of the four column dies 570 is greater than the height of the first bottom die 510 and the second bottom die 520; each over-rib hole 571 is a long waist hole penetrating through the bottom of the corresponding column die 570, thereby facilitating demolding.

[0084] In the present application, the length of the side die can be adjusted to match different lengths of prefabricated balcony plates 200 for flexible adjustment. The four column dies 570 can reserve the beam-column connection node 240 during the pouring process and provide the transverse steel bars 250 and the longitudinal steel bars 260 to pass through, thereby reducing the complex process, reducing the cost of the mold, and having high versatility.
