Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments.

< example one >

As shown in fig. 1 to 4, the present invention provides a frame body 13 for manufacturing a prefabricated part, which includes a main frame 2 and at least one assembling portion frame 3 assembled with the main frame 2. On the cross section of the framework body 13, at least part of the assembly part framework 3 protrudes out of the main framework 2 by a preset distance, which can be understood as that the assembly part framework 3 enables the framework body 13 to have at least one protruding structure; main part skeleton 2 and assembly portion skeleton 3 all include a plurality of interval distribution indulge muscle 21, and main part skeleton 2 with assemble 3 shares at least one and indulge muscle 21, and at least one is indulged muscle 21 and is belonged to main part skeleton 2 and assembly portion skeleton 3 simultaneously that this is said, can save the preparation and indulge the reinforcing bar volume that muscle 21 used to and can strengthen the firm degree after main part skeleton 2 and assembly portion skeleton 3 splice each other. Straight dotted lines in fig. 2, fig. 3 and the like schematically separate the main body frame 2 and the assembly portion frame 3; for the sake of simplicity of the drawings, the stirrups 4 between the longitudinal bars 21 on the side of the main body framework 2 near the straight dashed line are not shown in the partial drawings, and can be understood with reference to fig. 6(a) to 6 (c).

Further, referring to fig. 2 and 3, at least a part of the longitudinal ribs 21 of the assembly portion framework 3 protrudes from the main body framework 2 by a predetermined distance, such a longitudinal rib 21 protruding from the main body framework 2 by a predetermined distance may be referred to as an outer longitudinal rib 31, and it can be understood that the outer longitudinal rib 31 is at least a part of the protruding structure formed by the assembly portion framework 3. On one hand, the splicing part framework 3 is positioned at the edge part of the whole framework body 13 relative to the main framework 2, and the probability of collision and other situations is higher, so that more longitudinal bars 21 are needed to restrain the concrete around the splicing part framework; on the other hand, another longitudinal rib 21 of the assembly part framework 3 is shared with the main body framework 2, which can be used for connecting the assembly part framework 3 and the main body framework 2, and the connection can be completed without too many shared longitudinal ribs 21. Therefore, the number of the outer longitudinal ribs 31 can be set to be more than or equal to the number of the longitudinal ribs 21 shared by the main body framework 2 and the splicing part framework 3, so that the total usage amount of the longitudinal ribs 21 in the splicing part framework 3 can be reduced on the premise of meeting the use requirement of the splicing part framework 3, and the production cost is reduced; meanwhile, the total production time can be reduced due to the use of the smaller number of the longitudinal ribs 21.

Further, with reference to fig. 2 and fig. 3, the maximum distance between the outer longitudinal rib 31 of the assembly portion framework 3 and the main body framework 2 is La, the maximum predetermined distance Lb by which the assembly portion framework 3 protrudes from the main body framework 2 is Lb, and Lb is greater than or equal to La. This is because the outer longitudinal ribs 31 may be only a part of the outer convex structure of the assembled frame 3, and the frame body 13 may further include other components, such as the stirrups 4 connecting the outer longitudinal ribs 31 and the outer longitudinal ribs 31, or a positioning member for positioning the entire frame body 13.

Further, referring to fig. 1 to 4, the framework 13 further includes a plurality of stirrups 4, the stirrups 4 connect at least some adjacent longitudinal bars 21, and the adjacent longitudinal bars 21 are connected to each other, so that the plurality of longitudinal bars 21 can be regarded as an integrated stressed force-bearing structure, thereby improving the compression and tension resistance of the whole framework 13, and avoiding the occurrence of safety accidents in the use process due to the instability of a part of the prefabricated component formed by the framework 13 after the failure of a single longitudinal bar 21. For the convenience of production, the stirrup 4 is usually arranged on the outer side of the longitudinal rib 21, so that at least part of the stirrup 4 is further away from the main body part than the outer longitudinal rib 31 in the convex part of the erection portion framework 3, at which time Lb > La as described above. Of course, if another member such as the stirrup 4 is provided inside the longitudinal rib 21, Lb is La.

Further, referring to fig. 3, the stirrup 4 has an inwardly recessed bending section 41 between the connected longitudinal ribs 21, which can improve the strength of the frame 13 and the prefabricated member, so that the frame has a stronger ability to bear external loads.

Further, referring to fig. 4, the stirrup 4 includes stirrup-encrypting regions 42 near both ends of the longitudinal ribs 21, because the prefabricated parts are usually required to contact with the soil or other prefabricated parts at the ends, and the dense stirrup 4 at the ends can prevent the head of the prefabricated part from being damaged or failed during use. Another advantage of providing the thickened areas only at the ends of the longitudinal ribs 21 is that the amount of the stirrups 4 used can be reduced, and the stirrups 4 are usually made of steel bars, so that the amount of the steel bars used can be reduced, and the production cost can be reduced. In order to balance the whole framework body 13, the stirrup-clamping areas 42 at the two ends of the longitudinal bar 21 can be set to be approximately the same, so that inconvenience in transportation and lifting can be reduced.

The embodiment has the advantages that the prefabricated member comprises a main body framework 2 and at least one assembling part framework 3 which can be spliced with the main body framework 2, and the assembling part framework 3 at least partially protrudes out of the main body framework 2 for a preset distance, so that concrete at each position in the prefabricated member can be uniformly restrained; main part skeleton 2 and assembly portion skeleton 3 all include a plurality of vertical muscle 21 and share at least one and indulge muscle 21, can improve main part skeleton 2 and assemble the joint strength between the skeleton 3, improve the overall structure intensity of the prefabricated component of its production. In addition, by arranging the stirrups 4 to connect at least part of the adjacent longitudinal bars 21, the strength of the framework body 13 and the prefabricated member can be improved, and the capacity of bearing external load is stronger.

< example two >

In the present embodiment, the same portions as those in the first embodiment are given the same reference numerals, and the same description is omitted.

Compared with the first embodiment, the framework 13 for manufacturing prefabricated parts provided by the present embodiment has the following different structural design:

please refer to fig. 5, and additionally refer to fig. 1 to 4. The framework body 13 comprises a main framework 2, a male side assembling part framework 32 and a female side assembling part framework 33; the male side assembling part framework 32 is a convex part relative to the main body framework 2, and the female side assembling part framework 33 is a convex concave part relative to the main body framework 2; the maximum preset distance Lc that the male assembly part framework 32 protrudes out of the main body framework 2 is the maximum preset distance Ld that the female assembly part framework 33 protrudes out of the main body framework 2, and the maximum preset distance Ld is larger than or equal to Lc. This is because the male-side assembling part framework 32 and the female-side assembling part framework 33 in the assembling part framework 3 need to be adapted to each other, and the concrete protective layer thicknesses of the male-side assembling part framework 32 and the female-side assembling part framework 33 are generally the same; the space formed by the female side assembling part framework 33 can accommodate the space occupied by the male side assembling part framework 32 only when the convex distance Ld of the female side assembling part framework 33 is larger than or equal to the convex distance Lc of the male side assembling part framework 32.

In order to ensure that the prefabricated part formed of the female-side makeup portion skeleton 33 can be spliced with the prefabricated part formed of the male-side makeup portion skeleton 32, it is preferable to set the female-side makeup portion skeleton 33 outward projecting distance Ld to be greater than the outward projecting distance Lc of the male-side makeup portion skeleton 32. Thus, a certain margin can be left, and the female side assembling part framework 33 can accommodate the male side assembling part framework 32.

Further, the cross-sectional area of the main body frame 2 is larger than that of the built-up portion frame 3, which means that the space occupied by the main body frame 2 is larger than that occupied by the built-up portion frame 3 in the finally formed prefabricated member. This is because the main framework 2 is an integral part of the prefabricated member, the assembly part framework 3 is a part of the prefabricated member which is assembled with other prefabricated members, and the bearing capacity of the prefabricated member formed by the main framework 2 is better than that of the prefabricated member formed by the assembly part framework 3, so that the proportion of the main framework 2 in the framework body 13 should be increased as much as possible. Therefore, setting the size of the main body frame 2 to be larger than the size of the split portion frame 3 can improve the load bearing capacity of the prefabricated member formed of the entire frame body 13.

The advantage of this embodiment lies in, assembles a skeleton 33 through setting up public side and assembling a skeleton 32 and female side, can realize retraining the concrete of the different demands departments of prefabricated component, so be equivalent to adopt corresponding portion skeleton 3 of assembling according to the actual shape of prefabricated component, can increase the suitability of assembling a skeleton 3. In addition, the cross sectional area of the main body frame 2 is set to be larger than that of the split part frame 3, the proportion of the main body frame 2 in the prefabricated part formed finally can be increased, and the stability and the reliability of the prefabricated part are improved.

please refer to fig. 6(a) to 6(c), and refer to fig. 1 to 5 for assistance. Fig. 6(a) to 6(c) each include a male side sub frame 32 and two female side sub frames 33, and the two female side sub frames 33 together form a convex recess with respect to the main body frame 2. The existing framework 13 manufacturing equipment can only manufacture the framework 13 with the conventional shape, the framework 13 with the special shape is difficult to manufacture, and the efficiency and the quality cannot be ensured; the speed is too slow and the efficiency is too low when the framework body 13 is manufactured manually, so that the production period is long and the cost is high. Therefore, the main body framework 2 and the assembly part framework 3 in the framework body 13 are arranged to be of split structures, the main body framework 2 and the assembly part framework 3 in conventional shapes can be manufactured through mechanical equipment, and then the main body framework 2 and the assembly part framework 3 are connected through special equipment or manually, so that the production efficiency is improved as much as possible on the premise of meeting the quality requirement. Specifically, the splicing part framework 3 is connected with the main body framework 2 through one or more modes of welding, binding and mechanical connection.

Specifically, the longitudinal bars 21 and/or the stirrups 4 of the main body framework 2 are connected with the longitudinal bars 21 and/or the stirrups 4 of the assembly part framework 3, and because the longitudinal bars 21 and the stirrups 4 are mostly steel bars and can be used for bearing force, theoretically, the main body framework 2 and the assembly part framework 3 can be of an integrated structure as long as any two of the longitudinal bars 21 and the stirrups 4 are connected. In actual use, the longitudinal beads 21 and the longitudinal beads 21, the longitudinal beads 21 and the stirrups 4, and/or the stirrups 4 and the stirrups 4 are connected by considering the overall strength of the skeleton body 13, the manufacturing process, and other conditions.

The embodiment has the advantages that the main body framework 2 and the splicing part framework 3 are arranged into the split structure, so that equipment special for manufacturing the framework body 13 with a complex shape is not required to be manufactured, and the difficulty in manufacturing the framework body 13 is reduced; meanwhile, the main body framework 2 and the assembling part framework 3 are connected in one or more modes of welding, binding and mechanical connection, so that the main body framework 2 and the assembling part framework 3 can be connected in place, and a stable integrated stress structure is formed.

This is because adjacent prefabricated components 1 can be combined to form a connected and fastened integrated structure through the assembling portion 12, if the longitudinal ribs 21 in the assembling portion 12 are closer to the head of the assembling portion 12, the thickness of a concrete protective layer near the longitudinal ribs 21 at the head of the assembling portion 12 is thinner, the longitudinal ribs 21 are exposed due to collision in the assembling process or daily transportation process of the assembling portions 12 of the adjacent prefabricated components 1, and the effect of protecting the internal longitudinal ribs 21 cannot be achieved; if the longitudinal ribs 21 in the assembling portion 12 are far from the head of the assembling portion 12, the thickness of the concrete protective layer near the longitudinal ribs 21 at the head of the assembling portion 12 is thick, the degree of constraint of the concrete at the head of the assembling portion 12 is weak, the concrete is collided in the assembling process of the assembling portions 12 of the adjacent prefabricated components 1 or the daily transportation process, the structure of the assembling portion 12 of the prefabricated components 1 is not in accordance with the regulations, and the connection between the adjacent prefabricated components 1 cannot be pulled and fixed.

Further, with reference to fig. 9 and 10, the prefabricated parts 1 include a main body 11, a male assembly portion 12a and a female assembly portion 12b, and the male assembly portion 12a of one prefabricated part 1 can be connected and fastened with the assembly structure formed by the female assembly portions 12b of the adjacent prefabricated parts 1. It can be understood that if a single prefabricated part 1 includes the male-side assembling portion 12a and the female-side assembling portion 12b, three or more prefabricated parts 1 can be assembled with each other; if a single prefabricated part 1 comprises only one splicing section 12, it is possible to splice only two prefabricated parts 1 to one another; the design of the sub-assembly 12 is determined by the requirements of the application. The male side assembling portion 12a and the female side assembling portion 12b each include a plurality of longitudinal ribs 21 disposed at a predetermined distance from the head of the male side assembling portion, and the longitudinal ribs 21 disposed at a predetermined distance from the head of the female side assembling portion may be referred to as boundary ribs 34.

Specifically, please continue to refer to fig. 9 and 10, and additionally refer to fig. 5.

This is because if the boundary ribs 34 are too close to the head of the splicing part 12, the thickness of the concrete protective layer of the framework 3 of the splicing part is relatively thin; if the distance between the boundary rib 34 and the head of the assembling portion 12 is too far, the thickness of the concrete protective layer of the assembling portion framework 3 is thick, and the phenomenon that the overall structure of the framework body 13 is unbalanced due to the fact that the distance between the boundary rib 34 and the longitudinal rib 21 in the main framework 2 is too short easily occurs, and the overall performance of the prefabricated part 1 is affected.

Further, the thickness of the concrete protection layer at the head of the splicing part 12 where the boundary ribs 34 are located is not less than 20 mm. The thickness of the concrete protective layer is generally determined in accordance with the overall size of the prefabricated part 1, the strength of the concrete, the diameter of the longitudinal ribs 21, and the like, but the thickness should be set to not less than 20mm due to the wear in practical use and the consideration of easy demolding during the production process.
