< example one >

The base modeling part 7 can be in an integrated structure or detachably connected with the assembling modeling part.

Furthermore, the assembling modeling part is arranged on the side wall of the base modeling part 7 perpendicular to the stretching direction, and the stretching modeling structure can slide along the stretching direction, which is equivalent to the situation that the adjacent prefabricated enclosure components 1 are butted with each other through the side wall and the side wall. The tensioning direction generally refers to the extension direction of the rigid framework in the prefabricated building envelope 1.

Specifically, the assembling modeling part comprises a first modeling part 2 and/or a second modeling part 3, and the first modeling part 2 and the second modeling part 3 both comprise at least one bending section; the first modeling portion 2 is used for keeping the appearance of the first assembling portion at the end portion of the prefabricated enclosure component 1, the second modeling portion 3 is used for keeping the appearance of the second assembling portion at the end portion of the prefabricated enclosure component 1, and the adjacent prefabricated enclosure components 1 can be connected and pulled firmly through an assembling structure formed by the first assembling portion and the second assembling portion which are located on the assembling side 11 of the prefabricated enclosure component 1.

Specifically, the stretch-formed structure includes at least one pull plate 4, and at least one pull plate 4 has a first forming portion 2 and/or a second forming portion 3. Specifically, one of the first and second forming portions 2 and 3 is provided on one tension plate 4, and the other is provided on the other tension plate 4. It can be understood that the prefabricated building envelope members 1 produced by the two tension plates 4 respectively provided with the modeling part I2 and the modeling part II 3 can be mutually assembled. Or the modeling part I2 and the modeling part II 3 are arranged on the same tensioning plate 4, and the prefabricated enclosure components 1 produced by the same tensioning plate 4 can be mutually assembled.

Referring to fig. 3 and 4, the first modeling portion 2 and the second modeling portion 3 are arranged on the same tensioning plate 4, so that the prefabricated enclosure components 1 manufactured on the same tensioning plate 4 can be assembled end to end, and the prefabricated enclosure components 1 manufactured by the tensioning modeling structure of each tensioning plate 4 can be assembled with two other prefabricated enclosure components 1. Please refer to fig. 3, fig. 4, fig. 9 and fig. 10, it can be understood that a plurality of first modeling portions 2 and second modeling portions 3 can be disposed on the same tension plate 4, even other modeling portions different from the first modeling portions 2 and the second modeling portions 3, as long as each modeling portion has a modeling portion capable of cooperating with the modeling portion, so that the prefabricated enclosure member 1 made of one tension plate 4 can be assembled with more than two prefabricated enclosure members 1, thereby increasing the types of the integrally assembled enclosure structure, performing any splicing as a conventional building block, and improving the application range of the prefabricated enclosure member 1.

Referring to fig. 3, the first modeling portion 2 and the second modeling portion 3 are distributed on the side wall of the stretch panel 4 corresponding to the assembling side 11 of the prefabricated enclosure component 1, the first modeling portion 2 and the second modeling portion 3 are distributed on the stretch panel 4 at the same height, and the first modeling portion 2 and the second modeling portion 3 can form a concave-convex matching structure. Under the condition, the adjacent prefabricated enclosure components 1 can be assembled end to end, and the integrated enclosure structure formed by the prefabricated enclosure components can be an annular structure or a plate-shaped structure with a linear extending direction.

As shown in fig. 5 to 7, if only one molding part 2 or one molding part two 3 is provided on the tension plate 4, only two prefabricated building envelopes 1 can be assembled with each other. As shown in fig. 9 and 10, if two or more modeling portions 2 or two modeling portions 3 are disposed on the tensioning plate 4 and located at different sides, two or more prefabricated enclosure components 1 can be assembled with each other. It can be understood that the prefabricated enclosure components 1 can be assembled into a plate-shaped structure or a closed annular structure by combining the prefabricated enclosure components 1 according to the shape of the prefabricated enclosure components 1 and the assembling direction of the prefabricated enclosure components 1.

Further, as shown in fig. 7 and 8, a first limiting modeling portion 21 is arranged on a side wall of the first modeling portion 2 parallel to the stretching direction, a second limiting modeling portion 31 is arranged on a side wall of the second modeling portion 3 corresponding to the first limiting modeling portion 21, the first limiting modeling portion 21 and the second limiting modeling portion 31 can respectively keep the shapes of the first limiting portion and the second limiting portion at the end of the prefabricated enclosure component 1, and the adjacent prefabricated enclosure components 1 form a drawing structure resisting the acting force of the prefabricated enclosure components 1 in the arrangement direction through the matching of the first limiting portion and the second limiting portion.

Further, the first shaping portion 2 is provided with the first limiting shaping portions 21 on at least two side walls parallel to the stretching direction, and at least two side walls provided with the first limiting shaping portions 21 are arranged oppositely, so that the two adjacent prefabricated enclosure components 1 form opposite-pulling balance, large bending moment is avoided when the prefabricated enclosure components are subjected to drawing force, and the two adjacent prefabricated enclosure components 1 are prevented from rotating or being misplaced when the prefabricated enclosure components are subjected to drawing force.

Further, the first modeling portion 2 comprises at least one tenon 51 and/or a groove 52, and the second modeling portion 3 comprises a groove 52 and/or a tenon 51 corresponding to at least part of the first modeling portion 2; the tenon 51 and the groove 52 are provided with bent sections, and the bent sections in the tenon 51 and the bent sections in the groove 52 are at least partially matched. For ease of manufacture, a tongue 51 is typically used in conjunction with a groove 52; however, it is also possible that two or more tongues 51 cooperate with one and the same groove 52 at the same time, when the tongues 51 and grooves 52 are dimensioned, as shown in fig. 11.

Further, with reference to fig. 7 and 8, the embodiment will be described by taking an example in which the first forming portion 2 includes a groove 52 and the second forming portion 3 includes a matched tenon 51. The groove 52 is provided with a first limit modeling part 21, the first limit modeling part 21 is provided with a first locking surface 21a, the included angle between the first locking surface 21a and the concave direction of the groove 52 is alpha, and alpha is more than 0 degree and less than 180 degrees; the tenon 51 is provided with a second limit modeling part 31, a second locking surface 31a is arranged on the second limit modeling part 31, and the second locking surface 31a is parallel to the first locking surface 21 a. The first limiting surface formed by the first locking surface 21a is located on the first limiting portion, and the second limiting surface formed by the second locking surface 31a is located on the second limiting portion. In the present embodiment, the maximum vertical dimension L1 from the second locking surface 31a to the other side of the tongue 51 is greater than the minimum vertical dimension L2 from the first locking surface 21a to the other side of the groove 52, vertical referring to the direction perpendicular to both the tensioning direction and the inward recess direction of the groove 52. It will be appreciated that the first locking surface 21a is part of the bend in the first formation 2 and the second locking surface 31a is part of the bend in the second formation 3.

It can be understood that when two adjacent prefabricated enclosure components 1 are subjected to the acting force of being far away from each other, the first limiting surface in the first limiting portion is in contact with the second limiting surface in the second limiting portion, and the first limiting surface and the second limiting surface are parallel, so that the first limiting surface and the second limiting surface are in surface contact, the resistance is strong, and the two adjacent prefabricated enclosure components 1 can be prevented from being far away from each other. If two adjacent prefabricated enclosure components 1 are subjected to mutually approaching acting force, the groove bottom of the assembly structure formed by the groove 52 and the convex top of the assembly structure formed by the tenon 51 are mutually pressed, so that the two adjacent prefabricated enclosure components 1 are prevented from approaching each other. Through the integration of the two conditions, the drawing structure which can resist the acting force of the prefabricated enclosing components 1 in the arrangement direction together can be formed between the two adjacent prefabricated enclosing components 1 through the matching of the first limiting part and the second limiting part.

Meanwhile, the size of the included angle alpha between the first locking surface 21a and the concave direction of the groove 52 is set to be within the range of 0 degrees < alpha < 90 degrees as much as possible, so that the limitation failure caused by the damage or fracture of the corner due to the overlarge local stress born by the corner when the first limiting part and the second limiting part are subjected to larger impact force is avoided.

Further, with continuing reference to fig. 2, 7 and 8, the side walls of the first modeling portion 2 and the second modeling portion 3 are provided with a notch 22 penetrating along the tensioning direction, the notch 22 is used for maintaining the shape of the material injection hole 12 at the end of the prefabricated enclosure component 1, the material injection hole 12 is arranged on the assembling side 11 of the prefabricated enclosure component 1, and the material injection hole 12 penetrates through the prefabricated enclosure component 1 in the tensioning direction. It will be appreciated that the notches 22 are also part of the bend in the built-up moulding.

When two adjacent prefabricated enclosure components 1 are assembled in place, the two adjacent prefabricated enclosure components are mutually abutted under most conditions, namely the two adjacent prefabricated enclosure components can be regarded as an integrated assembled enclosure structure, but the two adjacent prefabricated enclosure components 1 cannot be regarded as a sealed integrated assembled enclosure structure because a group of surfaces or a plurality of groups of surfaces which are mutually assembled cannot be completely parallel in the production and manufacturing process and the angle of the two adjacent prefabricated enclosure components 1 entering a soil body has construction deviation during construction. The gap 22 is arranged, so that the assembling side 11 of the prefabricated enclosure components 1 extends and forms a through material injection hole 12, after the prefabricated enclosure components 1 are assembled in place, other fillers such as concrete and the like can be injected through the material injection hole 12, and after the fillers are solidified between the prefabricated enclosure components 1, the gap between every two adjacent prefabricated enclosure components 1 is completely filled, so that the integrally assembled enclosure structure has the waterproof sealing capability.

It can be understood that the gap 22 is provided in the embodiment to form a cast-in-place structure between the adjacent prefabricated enclosure components 1, and the gap between the two prefabricated enclosure components 1 is completely filled by the cast-in-place structure to form a seamless integrated enclosure structure, and in addition, because the gap between the two adjacent prefabricated enclosure components 1 is usually very small, the absence of the gap 22 may cause the flowing speed of the filler to be too slow or the filler to be unable to fill the gap, and the provision of the gap 22 is equivalent to increase the channel space when the filler flows, and avoids the filler from being blocked in the flowing process to cause the gap between the two adjacent prefabricated enclosure components 1 not to be connected in place. The notches 22 are provided in both the first forming portion 2 and/or the second forming portion 3. Another reason why the notches 22 are formed at the positions corresponding to the side walls of the first modeling portion 2 and the second modeling portion 3 is that the material injection holes 12 formed by the notches 22 occupy the space of the concrete in the prefabricated enclosure components 1, the concrete can form a protective layer around the internal rigid framework, and the material injection holes 12 influence the thickness and the distribution condition of the protective layer, so that when the size of the notches 22 is fixed, the notches are formed on the modeling portions of two adjacent prefabricated enclosure components 1, the influence can be distributed on the two prefabricated enclosure components 1, and the situation that one of the two prefabricated enclosure components has excessive stress concentration or weak structural strength is avoided.

Meanwhile, referring to fig. 1 to 11, the stretch-draw structure is provided with a stretch-draw rod mounting hole 63, and the stretch-draw rod mounting hole 63 is used for connecting with a stretch-draw rod. It can be understood that the stretching modeling structure is connected with the stretching rod through the stretching rod mounting hole 63 and then connected with the prestress equipment, and the rigid framework of the prefabricated enclosure component 1 can be stretched. For one-end tensioning and two-end tensioning in the conventional tensioning method, the tensioning modeling structure can be normally used, and the tensioning modeling structure is arranged at one end or two ends of the rigid framework.

The embodiment has the advantages that the stretch-draw modeling structure comprises a base modeling part 7 and an assembling modeling part at least positioned on one side of the base modeling part 7, and the maximum cross section outer contour of the stretch-draw modeling structure is consistent with the cross section outer contour of the prefabricated enclosure component 1, so that the stretch-draw modeling structure can model the whole end part of the prefabricated enclosure component 1; the maximum cross section outer contour line of the assembling modeling part is provided with at least one bending section, and the bending section can enable the end surface of the prefabricated enclosing member 1 to have the same shape as the end surface of the prefabricated enclosing member. The stretch-draw structure can model the end face of the prefabricated enclosure component 1, so that the end face of the prefabricated enclosure component 1 can be provided with a shape structure communicated with the side face of the prefabricated enclosure component, and the adjacent prefabricated enclosure components 1 can be spliced in place.

In addition, the first modeling part 2 and the second modeling part 3 are arranged on one tensioning plate 4 simultaneously, and the prefabricated enclosure components 1 can be manufactured and assembled through the tensioning modeling structure where the tensioning plate 4 is located, so that an integrally assembled enclosure structure is formed, the types and the number of the tensioning plates 4 and even the tensioning modeling structures are reduced, and the production cost is reduced. Meanwhile, in the actual use process of a construction site, because each prefabricated enclosure component 1 is provided with the first assembling part and the second assembling part, any two prefabricated enclosure components 1 can be spliced, the time and the process for selecting and moving the prefabricated enclosure components 1 by workers are reduced, and the construction efficiency is improved.

In addition, the first limiting modeling part 21 is arranged on the first modeling part 2, the second limiting modeling part 31 is arranged on the second modeling part 3, and the end parts of the first limiting part and the second limiting part can be modeled on the corresponding prefabricated enclosure component 1 by the tension modeling structure, so that the prefabricated enclosure component 1 can be further helped to bear stress and load in the arrangement direction; at least two groups of corresponding limiting modeling parts are arranged, so that the prefabricated enclosing member 1 can be prevented from rotating or being misplaced when stressed.

In addition, gaps 22 are formed in the first modeling portion 2 and/or the second modeling portion 3, gaps between the adjacent prefabricated enclosure components 1 can be filled, and therefore the sealed and waterproof integrated assembled enclosure structure can be formed after the adjacent prefabricated enclosure components 1 are assembled.

Compared with the first embodiment, the present embodiment provides a tension structure for manufacturing a prefabricated building envelope 1 with such a different structural design:

referring to fig. 12, each of the first and second forming portions 2 and 3 includes a tongue 51 and a groove 52, and the contour line of the tongue 51 and the contour line of the groove 52 at least partially run in the direction perpendicular to the tensioning direction. Specifically, referring to fig. 12, the tenon 51 and the mortise 52 on the same modeling portion form an angle symmetric relationship with respect to the side wall of the tensioning plate 4 and an angle β formed by the side wall passing through the center 0 of the side wall perpendicularly, that is, the first modeling portion 2 and the second modeling portion 3 have the same structure after the tensioning plate 4 rotates 180 degrees along a plane perpendicular to the tensioning direction.

In the case shown in fig. 12, the first and second profiles 2, 3 have the same number of tongues 51 and grooves 52. In the actual use process, the number of the tenons 51 of the two prefabricated building enclosures 1 can be different, for example, as shown in fig. 11, after the tensioning plate 4 is rotated by 180 degrees along the plane perpendicular to the tensioning direction, even if the structures of the first modeling part 2 and the second modeling part 3 are different, the assembly part two formed by the modeling part two 3 on one prefabricated building enclosure 1 can be in tension fit with the assembly part two formed by the modeling part two 3 on the other prefabricated building enclosure 1. It can be understood that the first assembling part formed by the modeling part one 2 on one prefabricated enclosing member 1 can also form a pulling and fixing fit with the first assembling part formed by the modeling part one 2 of the other prefabricated enclosing member 1.

The embodiment has the advantages that the first modeling part 2 and the second modeling part 3 are arranged on the same tensioning plate 4, the first modeling part 2 and the second modeling part 3 have the same structure or can form a groove adaptive multi-tenon after the tensioning plate 4 rotates 180 degrees along a plane vertical to the tensioning direction, the resource and time wasted by adjusting the positive and negative sequence of the prefabricated enclosure components 1 in the use process of a construction site can be effectively reduced, unnecessary construction loss is reduced, and the construction efficiency is improved.

Specifically, referring to fig. 14, the supporting member 42 includes a rib 42a, and the rib 42a plays a role of keeping the tension plate 4 from tilting, and the situation shown in the figure is a typical triangular support with strong force bearing capacity. Of course, other structures capable of supporting the tensioning plate 4 may be used.

Further, referring to fig. 15, the supporting member 42 includes a rib plate 42a and an auxiliary plate 42b, and the rib plate 42a connects the tension plate 4 and the auxiliary plate 42 b.
