Description

Technical Field

[0001] The present invention relates to the field of building formwork forming equipment, and specifically relates to a production device for precast hollow formwork with cross holes inside. Background Art

[0002] Precast hollow formwork has the characteristics of high production efficiency, convenient transportation and hoisting. Chinese Patent CN102581939B discloses precast reinforced concrete hollow formwork with cross holes inside. By setting through channels that penetrate vertically and horizontally, only a small amount of splicing and pouring between formworks is required at the building construction site to construct a wall that meets the requirements. Moreover, due to the presence of cross holes, it is convenient for the operation of threading steel bars.

[0003] However, compared with traditional precast hollow formwork that only has through holes in the length direction, precast hollow formwork with cross holes has greater production difficulty, and ordinary mandrels cannot produce precast hollow formwork with cross holes.

[0004] In view of this, the applicant of the present invention has conducted in-depth research on the above defects in the prior art, and thus this case has arisen. Summary of the Invention

[0005] The main purpose of the present invention is to provide a production device for precast hollow formwork with cross holes inside, which has the characteristic of efficiently producing precast hollow formwork with cross holes inside.

[0006] To achieve the above object, the solution of the present invention is:

[0007] A production device for precast hollow formwork with cross holes inside, which includes a mold cavity and a plurality of vertically arranged parallel mandrels. The vertical mandrel includes a mandrel body and a plurality of first telescopic core tubes. A plurality of first sliding holes are formed on the side of the mandrel body at intervals along the vertical direction, and the first telescopic core tubes are slidably arranged in the first sliding holes along the horizontal direction; a first driving mechanism for driving the first telescopic core tubes to slide is arranged inside the mandrel body, and the first driving mechanism drives the first telescopic core tubes to switch between two states: completely located inside the mandrel body and extending out of the mandrel body.

[0008] Further, two first telescopic core tubes are symmetrically arranged at the same height on the side of the mandrel body, and the end faces of the first telescopic core tubes abut against the end faces of the first telescopic core tubes opposite to adjacent vertical mandrels when extended.

[0009] Further, the cross section of the mandrel body is rectangular, and the cross section of the first telescopic core tube is circular.

[0010] Further, a sealing ring for cooperating with the first telescopic core tube is arranged in the first sliding hole.

[0011] Furthermore, the first driving mechanism includes a vertical driving rod and a plurality of connecting support rods. The vertical driving rod slides vertically within the mandrel body. The two ends of the connecting support rod are respectively hinged to the first telescopic core tube and the vertical driving rod. The upper end of the vertical driving rod is connected to a driving part, and the driving part slides vertically on the upper part of the mandrel body.

[0012] Furthermore, a sliding groove is formed within the mandrel body, and the hinge shaft of the vertical driving rod and the connecting support rod slides along the sliding groove; the sliding groove is arranged on a mounting plate, and the mounting plate is installed on the mandrel body through a fixing member.

[0013] Furthermore, the mold cavity is surrounded by a front panel, a rear panel, a left side panel, a right side panel, and a bottom plate. An installation hole for fixedly installing the vertical mandrel is formed on the bottom plate.

[0014] Furthermore, a chassis is further arranged below the bottom plate. The left side panel and the right side panel are hinged to the chassis. The two ends of the front panel and the rear panel are respectively detachably connected to the left side panel and the right side panel; a top plate is further connected to the upper parts of the front panel, the rear panel, the left side panel, and the right side panel, and a through hole for the vertical mandrel to pass through is formed on the top plate.

[0015] Furthermore, second sliding holes are formed on both the left side panel and the right side panel at intervals from top to bottom. Second telescopic core tubes are slidably arranged on the second sliding holes, and second driving mechanisms for driving the second telescopic core tubes are formed on both the left side panel and the right side panel.

[0016] Furthermore, the second driving mechanism includes a telescopic cylinder and a connecting seat. The connecting seat is fixedly connected to the second telescopic core tube. The telescopic cylinder is fixedly connected to the left side panel or the right side panel, and the piston rod of the telescopic cylinder is connected to the connecting seat.

[0017] After adopting the above structure, a production device for a precast hollow formwork with cross holes inside the present invention has at least the following beneficial effects:

[0018] First, the vertical mandrel is vertically arranged within the mold cavity. The first telescopic core tube extends out of the mandrel body. The mandrel body and the first telescopic core tube respectively occupy the vertical hole and the horizontal hole of the hollow formwork. After the concrete is poured and initially solidified, the first driving mechanism drives the first telescopic core tube to retract into the mandrel body, and then the mandrel body is withdrawn in the vertical direction. By providing the first telescopic core tube that can be telescoped on the side of the mandrel body, the trouble of inconvenient placement of the horizontal hole forming die core is solved, and thus the production efficiency of the precast hollow formwork is greatly improved.

[0019] Second, the first driving mechanism adopts a vertical driving rod that moves vertically and is connected to the first telescopic core tube through a connecting support rod. By changing the position of the vertical driving rod, the position of the first telescopic core tube is adjusted.

[0020] Third, second telescopic core tubes are provided on the left side plate and the right side plate. The second telescopic core tubes occupy the positions of the horizontal holes at both ends of the precast hollow formwork during pouring. After pouring is completed, the second driving mechanism drives the second telescopic suction tube to move outward and separate from the precast hollow formwork.

[0021] Compared with the prior art, in the present invention, the horizontal holes of the precast hollow formwork are formed by the first telescopic core tubes that are telescopic on the core rod body, thus realizing the production of precast hollow formworks with cross holes, greatly improving the production efficiency of precast hollow formworks.

[0044] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail below through specific embodiments.

[0045] As Figures 1 to 17 shown, it is a production device for a prefabricated hollow template with cross holes involved in the present invention, including a mold cavity and a plurality of vertically arranged vertical mandrels 1. The vertical mandrels 1 include mandrel bodies 2 and a plurality of first telescopic core tubes 3. Preferably, the cross section of the mandrel body 2 is rectangular, and the cross section of the first telescopic core tube 3 is circular. A plurality of first sliding holes 21 are formed in the side part of the mandrel body 2 at intervals along the vertical direction, and the first telescopic core tubes 3 are slidably arranged on the first sliding holes 21 along the horizontal direction; a first driving mechanism 4 for driving the first telescopic core tubes 3 to slide is arranged in the mandrel body 2, and the first driving mechanism 4 drives the first telescopic core tubes 3 to switch between two states of being completely located inside the mandrel body 2 and extending out of the mandrel body 2.

[0046] Thus, the present invention relates to a production device for a precast hollow formwork with cross holes. The vertical mandrel 1 is vertically arranged in the mold cavity. The first telescopic core tube 3 extends out of the mandrel body 2. The mandrel body 2 and the first telescopic core tube 3 respectively occupy the vertical hole and the horizontal hole of the hollow formwork. After the concrete is poured and initially solidified, the first driving mechanism 4 drives the first telescopic core tube 3 to retract into the mandrel body 2, and then the mandrel body 2 is withdrawn in the vertical direction. By providing the first telescopic core tube 3 that can be telescoped on the side of the mandrel body 2, the trouble of inconvenient placement of the horizontal hole forming die core is solved, thus greatly improving the production efficiency of the precast hollow formwork 9. The first telescopic core tube 3 abuts against the adjacent vertical mandrel 1, so as to form a through horizontal hole.

[0047] As Figure 4 and Figure 17 shown, preferably, two first telescopic core tubes 3 are symmetrically arranged at the same height on the side surface of the mandrel body 2. The end surfaces of the first telescopic core tubes 3 abut against the end surfaces of the first telescopic core tubes 3 opposite to the adjacent vertical mandrels 1 when extended. In this way, after the first telescopic core tubes 3 opposite to the adjacent vertical mandrels 1 retract, interconnected horizontal holes are formed.

[0048] Preferably, as Figure 11 shown, a sealing ring 22 cooperating with the first telescopic core tube 3 is arranged in the first sliding hole 21. By providing the sealing ring 22, the sealing performance is further improved, and external concrete mortar is prevented from entering the mandrel body 2.

[0049] As Figures 8 to 11 shown, preferably, the first driving mechanism 4 includes a vertical driving rod 41 and a plurality of connecting support rods 42. The vertical driving rod 41 slides vertically in the mandrel body 2. The two ends of the connecting support rod 42 are respectively hinged to the first telescopic core tube 3 and the vertical driving rod 41. The upper end of the vertical driving rod 41 is connected with a driving part 43, and the driving part 43 slides vertically on the upper part of the mandrel body 2. The first driving mechanism 4 adopts the vertical driving rod 41 that moves vertically and is connected to the first telescopic core tube 3 through the connecting support rod 42. By changing the position of the vertical driving rod 41 through the driving part 43, the position of the first telescopic core tube 3 is adjusted.

[0050] Preferably, a chute 44 is formed in the mandrel body 2, and the hinge axis of the vertical drive rod 41 and the connecting support rod 42 slides along the chute 44; the chute 44 is arranged on the mounting plate 45, and the mounting plate 45 is mounted on the mandrel body 2 through a fixing member. The chute 44 realizes the horizontal limit of the vertical drive rod 41, ensuring that the vertical drive rod 41 can only move up and down. The mounting plate 45 is detachably connected to the mandrel body 2 through a fixing member, facilitating the installation of the chute 44. At the same time, after the mounting plate 45 is removed, the through hole on the mandrel body 2 through which the chute 44 passes also facilitates the maintenance and part installation inside the vertical mandrel 1.

[0051] Preferably, as Figure 6 and Figure 7 shown, the mold cavity is surrounded by a front panel 51, a rear panel 52, a left side panel 61, a right side panel 62 and a bottom plate 81, and a mounting hole 811 for fixedly mounting the vertical mandrel 1 is formed on the bottom plate 81. The vertical mandrel 1 is positioned through the mounting hole 811, thus simplifying the positioning structure of the vertical mandrel 1. Further, a chassis 82 is further arranged below the bottom plate 81, the left side panel 61 and the right side panel 62 are hinged on the chassis 82, and the two ends of the front panel 51 and the rear panel 52 are respectively detachably connected to the left side panel 61 and the right side panel 62; a top plate 83 is further connected to the upper parts of the front panel 51, the rear panel 52, the left side panel 61 and the right side panel 62, and a through hole for the vertical mandrel 1 to pass through is formed on the top plate 83. In this way, the top plate 83 and the mounting hole 811 together realize the position positioning of the vertical mandrel 1.

[0052] Furthermore, positioning pins 511 and pin seats 512 are arranged at the lower ends of the front panel 51 and the rear panel 52, and the front panel 51 and the rear panel 52 are positioned through the positioning pins 511 and the pin seats 512. When demoulding is required, the top plate 83 and the connections between the front panel 51, the rear panel 52 and the left side panel 61 and the right side panel 62 are removed, and then the front panel 51 and the rear panel 52 can be removed, and the left side panel 61 and the right side panel 62 are disengaged from the formed precast hollow template 9 around the hinge points on the chassis 82.

[0053] Preferably, as Figures 12 to 16As shown, second sliding holes 611 are formed on both the left side plate 61 and the right side plate 62 at intervals from top to bottom. A second telescopic core tube 613 is slidably arranged in the second sliding holes 611. A second driving mechanism 7 for driving the second telescopic core tube 613 is formed on both the left side plate 61 and the right side plate 62. Preferably, the second driving mechanism 7 includes a telescopic cylinder 71 and a connecting seat 72. The connecting seat 72 is fixedly connected to the second telescopic core tube 613. The telescopic cylinder 71 is fixedly connected to the left side plate 61 or the right side plate 62. The piston rod of the telescopic cylinder 71 is connected to the connecting seat 72. The second telescopic core tube 613 is arranged on the left side plate 61 and the right side plate 62. The second telescopic core tube 613 occupies the positions of the horizontal holes at both ends of the precast hollow form 9 during pouring. After pouring is completed, the second driving mechanism 7 drives the second telescopic suction tube to move outward to disengage from the precast hollow form 9. The end of the second telescopic core tube 613 can abut against the end of the opposite first telescopic core tube 3.

[0054] Preferably, the bottom plate 81 and the top plate 83 both form a first module 831 protruding into the die cavity. The first module 831 is semi-cylindrical. Second modules 612 protruding into the die cavity are formed on the left side plate 61 and the right side plate 62. The cross-section of the second module 612 is trapezoidal or triangular. The second module 612 is detachably connected to the left side plate 61 and the right side plate 62.

[0055] Compared with the prior art, the present invention forms the horizontal holes of the precast hollow form 9 through the first telescopic core tube 3 telescoping on the core rod body 2, thus realizing the production of the precast hollow form 9 with cross holes and greatly improving the production efficiency of the precast hollow form 9.

[0056] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
