The embodiment of the utility model discloses mould board for prefabricated component is the partly of production heterotypic prefabricated component mould, adopts with the template of other parts of mould to peg graft, and perhaps fasteners such as screws, bolt are connected, can do benefit to the nimble adjustment of mould length dimension, can the quick response market demand provide the heterotypic prefabricated component of required specification.
As shown in fig. 1 to 13, the mold plate 100 of the embodiment of the present invention includes a molding surface 1 and a splicing end, wherein the splicing end includes a first splicing end 7 and a second splicing end 8 respectively disposed at two longitudinal sides of the molding surface 1, which can be connected with other mold plates (such as the adjacent mold plate 200) of the mold to form a mold, and the longitudinal direction refers to the mold length direction (as shown by the arrow in fig. 1).
The mold cavity 300 is a cavity within the mold for receiving casting material to form a prefabricated component product. The boundary of the cavity 300 is formed by the wall surface of the interior of the mold from the entire mold, and particularly in the mold plate 100 of the present embodiment, the cavity 300 is partially formed by the interior wall surface (i.e., the molding surface 1) of the mold plate 100. In the mold plate 100 of the present embodiment, the structure of the end portion is changed to form the splicing end in consideration of the improvement of the connection manner with the adjacent mold plate 200, wherein a part of the splicing end is also formed with a wall surface on the inner side of the mold plate 100, but the wall surface is mainly used for connection with the adjacent mold plate 200, and the wall surface is not directly contacted with the casting material after the mold connection is formed, so that the inner wall surface portion of the mold plate 100 at the splicing end does not play a role of accommodating the casting material to form the product shape of the prefabricated member, and the subsequent description of the modeling surface 1 does not include the part.
In order to enable quick adjustment of the length dimension of the mold, the structure of the splicing end of the mold plate 100 is modified so that the mold plate 100 is detachably connected to the adjacent mold plate 200. In particular, the detachable connection structure may be provided only at the first splice end 7 or only at the second splice end 8, as in the embodiment presented in fig. 1, the detachable connection structure is provided only at the first splice end 7. Alternatively, detachable connection structures are provided at both the first splice end 7 and the second splice end 8, as in the example of embodiment shown in fig. 2, whereby the choice of a mold plate 100 with a single-sided detachable connection structure or a mold plate 100 with a double-sided detachable connection structure can be made according to the specific production requirements. In addition, as in the embodiment shown in fig. 2 and 3, the mold plate 100 is connected to the adjacent mold plate 200 by means of fasteners such as screws and bolts, and the connecting holes 4 are formed at the splicing end of the mold plate 100; in the embodiment shown in fig. 5 and 7, the mold plate 100 and the adjacent mold plate 200 may be connected by means of a plug-in connection, besides by means of fasteners such as screws and bolts, and the connecting groove 5 is cooperatively arranged at the first splicing end 7 and/or the second splicing end 8.
In order to improve the quick and reliable connection between the mold plate 100 and the adjacent mold plate 200, the splicing end is provided with an end connecting surface 2 detachably connected and matched with the adjacent mold plate 200 and an end positioning blocking surface 3 for limiting and positioning the adjacent mold plate 200. Specifically, the end connection surface 2 and the end positioning blocking surface 3 may be provided only at the first splicing end 7 or the second splicing end 8, or the end connection surface 2 and the end positioning blocking surface 3 may be provided at both the first splicing end 7 and the second splicing end 8.
When the mold plate 100 is required to be connected to an adjacent mold plate 200, the end positioning stop faces 3 can serve to position the adjacent mold plate 200 at least in the longitudinal direction of the mold cavity 300 (i.e., the longitudinal direction of the mold cavity 300). When the die plate 100 and the adjacent die plate 200 are fixed in a detachable connection mode through fasteners such as bolts, connecting holes 4 are formed in the end connecting surface 2, and the fasteners such as bolts penetrate through the connecting holes 4 to connect and fix the die plate 100 and the adjacent die plate; when the mold plate 100 and the adjacent mold plate 200 are connected and fixed in an inserting manner, the end positioning blocking surface 3 and the end connecting surface 2 of the splicing end form a connecting groove 5, and the adjacent mold plate 200 is inserted into the connecting groove 5 to realize the connection and fixation of the mold plate 100 and the adjacent mold plate 200.
In view of the convenience of the mold process, the end connecting surface 2 of the same splicing end may be coplanar with the end positioning blocking surface 3, i.e. the end connecting surface 2 and the end positioning blocking surface 3 are located on the same plane, such as the first splicing end 7 illustrated in fig. 3. Alternatively, the end connecting surface 2 may be angled with respect to the end positioning abutment surface 3 to allow for positioning limiting effects when the mold plate 100 is connected to an adjacent mold plate 200, thereby providing for both lateral and longitudinal positioning of the adjacent mold plate 200 when connected, as illustrated by the second splice end 8 of the example of fig. 3. And when the end connecting surface 2 and the end positioning blocking surface 3 of the same splicing end form an included angle, a plate thickness abrupt change section is formed on the plate body of the die plate 100.
The mold plate 100 of the embodiment of the present invention can be formed separately by the transition connection section of the special-shaped portion, that is, the molding surface 1 only presents the inclined plane shape of the transition connection section and inclines along the longitudinal central axis of the mold cavity 300; alternatively, the mold plate 100 may be integrally formed with the entire profiled portion, as shown in fig. 8, and the profiled surface 1 includes a concave section 11 at the middle and two inclined sections 12 respectively disposed at two longitudinal sides of the concave section 11.
In view of the convenience of manufacturing the mold plate 100, the exterior of the mold plate 100 may be designed to be flat, i.e., the exterior shape of the mold plate 100 does not have to conform to the shape of the inner molding surface 1; alternatively, the plate body of the mold plate 100 is designed to be inclined along the longitudinal central axis of the mold cavity 300 with reference to the molding surface 1, so that the amount of material used for manufacturing the mold plate 100 can be saved, the production cost can be controlled, and the product has certain price competitive advantage.
As shown in fig. 1 to 7 and fig. 9 and 10, when the mold plate 100 is separately molded with the transition joint ends of the profiled portions, the adjacent mold plates 200 respectively connected to the first splice end 7 and the second splice end 8 of the mold plate 100 are different in size, that is, the adjacent mold plates 200 respectively connected have different widths in the transverse direction of the mold cavity 300, thereby forming portions where the preform thickness is different. Accordingly, the first splice end 7 and the second splice end 8 are positioned at different distances from the central longitudinal axis of the mold cavity 300, e.g., the distance L1 (shown in fig. 1) from the central longitudinal axis of the mold cavity 300 at the first splice end 7 may be greater than or less than the distance L2 (shown in fig. 1) from the central longitudinal axis of the mold cavity 300 at the second splice end 8. Since the shape of the mold plate 100 may not be consistent with the molding surface 1, the mold plate 100 may be formed with different thicknesses, and therefore, the distance L1 between the first splicing end 7 and the longitudinal central axis of the cavity 300 or the distance L2 between the second splicing end 8 and the longitudinal central axis of the cavity 300 refers to the distance between the connecting portion of the first splicing end 7 or the second splicing end 8 and the adjacent mold plate 200 and the longitudinal central axis of the cavity 300.
As shown in fig. 8, when the mold plate 100 is integrally formed with the entire profile portion, since the reduced diameter portion is already formed in the mold plate 100, the adjacent mold plates 200 connected to the first splice end 7 and the second splice end 8 of the mold plate 100 have the same size, i.e., the distance L1 from the longitudinal central axis of the mold cavity 300 by the first splice end 7 is equal to the distance L2 from the longitudinal central axis of the mold cavity 300 by the second splice end 8.
As shown in fig. 1 to 10, in the mold plate 100 of the embodiment of the present invention, the end positioning blocking surface 3 of the splicing end may be disposed near the molding surface 1, or may be disposed far from the molding surface 1. When the end positioning blocking surface 3 is close to the molding surface 1, because the end positioning blocking surface 3 is directly contacted with the adjacent template 200, in order to prevent the connected adjacent template 200 from exceeding the molding surface 1 inwards and further extending into the mold cavity 300 to influence the shape of the prefabricated part finally formed, the side line of the end positioning blocking surface 3 close to the molding surface 1 is collinear with the side line of the molding surface 1, that is, in space, the end positioning blocking surface 3 is intersected with the molding surface 1 and two surfaces are respectively stopped at the position of the intersection line.
When the end positioning stops 3 are far from the molding surface 1, as illustrated in fig. 2, the end positioning stops 3 are located outside the mold plates 100 for limiting the positioning of the connected adjacent mold plates 200 in the longitudinal direction, while the end connecting surfaces 2 are used for fastening and fixing the adjacent mold plates 200. Considering that the fastening connection with the adjacent mold plate 200 does not affect the shape of the mold cavity 300, i.e. the mold plate 100 does not extend into the mold cavity 300 after being connected with the adjacent mold plate 200, the edge of the end connecting surface 2 is designed to be collinear with the edge of the molding surface 1, i.e. spatially, the end connecting surface 2 intersects the molding surface 1 and the two surfaces each end at the intersection line position, as in the example of fig. 2, a sharp corner is formed at the second splice end 8.
As shown in fig. 5, the end positioning block surface 3 is far away from the molding surface 1, and the end positioning block surface 3 is formed at the bottom of the connecting groove 5, and the end connecting surface 2 close to the molding surface 1 is similar to the example shown in fig. 2, and the side line thereof is collinear with the side line of the molding surface 1, so as to avoid the adverse effect on the mold cavity 300 after the mold plate 100 is connected with the adjacent mold plate 200, and further the adverse effect on the shape of the prefabricated part to be formed subsequently. Of course, the positions of the connecting grooves 5 may also move outwards continuously, i.e. away from the direction of the molding surface 1, at this time, the groove bottoms of the connecting grooves 5 still form the end positioning blocking surface 3 for longitudinally positioning and limiting the adjacent mold plates 200, and the side surfaces of the connecting grooves 5 may form the end connecting surface 2 for connecting and fixing with the adjacent mold plates 200, wherein the end connecting surface 2 close to the molding surface 1 may form a gap with the molding surface 1, and in order to avoid the influence on the shape of the mold cavity 300 after the mold plate 100 is connected with the adjacent mold plate 200, a boss may be designed on the connected adjacent mold plates 200 to be inserted into the position of the connecting groove 5, and the boss position may ensure that the side of the connected adjacent mold plate 200 facing the mold cavity 300 is flush with the.
As shown in fig. 5 and 7, the mold plate 100 of the embodiment of the present invention is connected to the adjacent mold plate 200 for enhancing the reliability thereof, and is connected to the fastening member by plugging, for example, the connecting holes 4 may be disposed on the end connecting surface 2 formed by the connecting grooves 5, specifically, the connecting holes 4 are disposed along the end connecting surface 2 at intervals, and the number of the connecting holes 4 or the interval between the connecting holes 4 may be determined by measurement in terms of the connecting efficiency and the connecting firmness. For example, when it is desired to improve the efficiency of the connecting work, that is, when the die plate 100 and the adjacent die plate 200 are connected, fasteners such as a small number of bolts can be fastened, and the interval of the connecting holes 4 can be appropriately increased; alternatively, when it is desired to make the connection between the mold plate 100 and the adjacent mold plate 200 more secure, the interval between the connecting holes 4 can be reduced appropriately.
The utility model discloses mould board 100 can dismantle when connecting when adopting the fastener with adjacent template 200, is equipped with connecting hole 4 at the end connection face 2 intervals of concatenation end, and is similar with establishing at connecting hole 4 of 5 end connection faces 2 of spread groove, and its interval can be based on the firm in connection nature of connecting operating efficiency and mould board 100 and adjacent template 200 and synthesize and weigh the affirmation. In addition, in order to facilitate the installation of fasteners during the connecting operation, such as fasteners which can install bolts and the like transversely or longitudinally or obliquely, the included angle alpha (shown in figure 1) between the axis of the connecting hole 4 and the longitudinal axis of the die cavity 300 is designed to be between 0 degrees and alpha degrees and less than or equal to 90 degrees.
As shown in fig. 7, in order to save the amount of material used for manufacturing the mold plate 100 and further to achieve an advantage in overall production cost control and market price of the prefabricated parts to be finally formed, the mold plate 100 is designed with weight-reducing structures such as weight-reducing holes (not shown) and weight-reducing grooves 6, specifically, the weight-reducing holes or the weight-reducing grooves 6 can be designed separately, or the weight-reducing holes and the weight-reducing grooves 6 can be provided simultaneously. The weight-reducing slots 6 may be provided at the end positions of the splice of the mould plate 100, i.e. towards the direction of connection with the adjacent mould plate 200, or the weight-reducing slots 6 may be provided on the outside of the mould plate 100, i.e. away from the moulding surface 1. In addition, the lightening holes and the lightening grooves 6 may be provided continuously and intermittently in the circumferential direction along the die plate 100. For example, a circle of lightening grooves 6 are machined along the circumferential direction of the die plate 100, or lightening grooves 6 or lightening holes are machined intermittently along the circumferential direction, and the specific pattern can be selected according to the needs.
The embodiment of the utility model provides an in, the cross section of mould board 100 can design into U-shaped, ring shape, multilateral annular, convex, L shape, a font etc to this prefabricated component that can be used to make different grade type such as heterotypic square pile, tubular pile, multiangular pile. As an example of fig. 9, a die plate 100 with a circular cross section for manufacturing the special-shaped pipe pile is shown, and as an example of fig. 10, a die plate 100 with a polygonal cross section for manufacturing the special-shaped polygonal pile is shown.
As shown in fig. 3 and fig. 11 for example, when the mold plate 100 of the embodiment of the present invention is used, the adjacent mold plates 200 are respectively close to the first splicing end 7 and the second splicing end 8 of the mold plate 100, taking the first splicing end 7 as an example, the adjacent mold plates 200 stop moving forward after contacting and abutting against the end positioning blocking surface 3 of the first splicing end 7, and the connecting holes 4 connected to the skirt boards 201 at the ends of the adjacent mold plates 200 are aligned with the connecting holes 4 of the end connecting surface 2 of the first splicing end 7, and then are connected and fixed by using fasteners such as bolts. Similarly, the adjacent template 200 stops moving forward after contacting and abutting against the end positioning blocking surface 3 of the second splicing end 8, and because the end connecting surface 2 of the second splicing end 8 forms an included angle with the end positioning blocking surface 3, the adjacent template 200 can be positioned in the transverse direction and the longitudinal direction at the same time, after the adjacent template 200 is limited by the end positioning blocking surface 3, the connecting hole 4 on the adjacent template 200 can be aligned with the connecting hole 4 on the end connecting surface 2 of the second splicing end 8, and then the adjacent template 200 and the connecting hole 2 are connected and fixed by using fasteners such as bolts. And in this example the fastening of the first splice end 7 secures the two together in the longitudinal direction and the fastening of the second splice end 8 secures the two together in the transverse direction.
In the example shown in fig. 2 and 12, the first splice end 7 is similar to the second splice end 8, and the end positioning baffle surface 3 and the end connecting surface 2 are also formed with an included angle, that is, the plate thickness abrupt change is formed at both ends of the die plate 100. Therefore, when the adjacent template 200 is connected with the first splicing end 7, the end positioning blocking surface 3 and the end connecting surface 2 can be used for positioning in the longitudinal direction and the transverse direction, and the connection positioning can be completed quickly. In addition, unlike the example shown in fig. 11, the fastening members of the first and second splicing ends 7 and 8 complete the connection and fixation of the mold plate 100 and the adjacent mold plate 200 in the transverse direction.

(
The comprehensive reduction coefficient, fc, the designed compressive strength value and Am, the minimum cross-sectional area of the pile body can be obtained, although the minimum cross-sectional area (namely the distance between the two nearest points on the modeling surface 1 from the longitudinal central axis of the die cavity 300, namely the cross-sectional area formed at the position of twice L1) of the variable-section solid pile is smaller than that of the constant-section solid pile, under the normal condition, the design requirement on the strength of the pile body is only higher than that of the soil body at the periphery of the pile body, the strength of the pile body designed according to the pile body strength calculation formula is far higher than that of the soil body at the periphery of the pile body, and the higher pile body strength design wastes more concrete materials and does not meet the development requirements of green, energy conservation and environmental protection of the concrete prefabricated member.
And through the comparison of the constant-section solid pile and the variable-section solid pile, the vertical limit bearing capacity of the pile body with the size meeting the calculation formula can be greatly improved on the premise of meeting the use requirement on the strength of the pile body.
Further, in order to secure the pile body strength of the pile body, the cross-sectional area of the pile body needs to be increased in the case of a decrease in the concrete strength grade. If the concrete strength grade is higher than or equal to C60, the local size parameter of the molding surface 1 is determined according to the formula Y which is more than or equal to 0.5864X +58.352, wherein Y is the lower limit value of the distance between the two points on the molding surface 1 which are closest to the longitudinal central axis of the molding cavity 300, and X is the lower limit value of the distance between the two points on the molding surface 1 which are farthest from the longitudinal central axis of the molding cavity 300.
Further, if the concrete strength level is higher than or equal to C40, the local dimension parameter of the molding surface 1 is determined according to the formula Y ≥ 0.6796X +67.635, where Y is the lower limit of the distance between the nearest two points on the molding surface 1 from the longitudinal central axis of the molding cavity 300, and X is the lower limit of the distance between the farthest two points on the molding surface 1 from the longitudinal central axis of the molding cavity 300.
The local dimensional parameters of the molding surface 1 are determined according to the formula Z which is less than or equal to 0.988X-13.589, wherein Z is the upper limit value of the distance between the two points on the molding surface 1 which are closest to the longitudinal central axis of the mold cavity 300, X is the lower limit value of the distance between the two points on the molding surface 1 which are farthest from the longitudinal central axis of the mold cavity 300, and X is more than or equal to 250 mm.
