Description

grating

This creation is about an architectural structure, especially a lattice panel.

Lattice structure is widely used in the current civil and construction engineering fields, especially in the construction of high-tech manufacturing plants, especially wafer manufacturing plants. Due to the earthquake resistance of the grid plate structure, most of the floor slabs of wafer factories today adopt the grid plate structure to resist vibration, so that precision process equipment can be stably installed on the floor of the factory building.

Cooperate with 預鑄 lattice panels and 預鑄 beams within the span range of 預鑄 concrete columns to form the floor slab of the factory building, which can best shorten the construction period and greatly reduce the number of construction labor. It is easy to carry and beautiful. In detail, the grid plate structure has the following advantages: because the grid plate unit is prefabricated, the precision and flatness are easy to control; the quality of the grid plate unit is good and uniform; the concrete is poured on site, and the grid plate can be completely combined; The strength of the grid plate is sufficient to support its own weight and construction load; only hoisting work is left on the construction site, which can save a lot of construction frames, and the construction movement line is good; and the construction period can be shortened.

In addition, the high-precision products in the high-tech industry, such as chips or wafers, need to strictly control the amount of dust around them during the manufacturing process, so as not to damage the product precision and reliability. The clean room is built with the lattice beam perforated floor structure, which uses positive pressure to push the dust out of the clean room through the lattice beam perforation, and then returns the clean air to the clean room again through the filtered return air. It is currently commonly used in The way high-tech factories are designed. However, since the grating needs to be designed with many perforations, in order to maintain the structural strength of the grating, the thickness of the grating must be increased, which will increase the manufacturing cost of the grating and indirectly limit the height of the floor.

Therefore, in order to solve the above-mentioned problems, it is long-awaited in the industry to provide a perforated grating panel, which has better structural strength without significantly increasing the thickness.

The plurality of first reinforcement cages respectively include a first main body part, which is embedded in the panel body and a first reinforcement part, extending from the first main body part, and extending outward from one of the four side surfaces along a first Axial extension. The plurality of second reinforcement cages respectively include a second main body part embedded in the panel body and a second rib outlet part extending from the second main body part and extending outward from the other of the four side surfaces along a first Two axial extensions, the first axial extension and the second axial extension are substantially perpendicular. A plurality of first supporting steel bars and a plurality of second supporting steel bars are respectively buried in the plate body, staggered with each other and arranged so that the plurality of perforations are located in the staggered structure formed by the plurality of first supporting steel bars and the plurality of second supporting steel bars. in space.

In some other embodiments, the longitudinal ribs 93 may be omitted.

In one embodiment, the top wall 92 of the mold 90 further includes a plurality of perforations 99 disposed above at least one longitudinal rib 93 (below in the drawing). The projected position of at least one longitudinal rib 93 on the top wall 92 overlaps with the upper through hole 99 . In one embodiment, the number of perforations 99 corresponds to the number of longitudinal ribs 93 , that is, a perforation 99 is disposed above each longitudinal rib 93 . In some other embodiments, the through hole 99 may be omitted.

The mold 90 in an embodiment according to the present invention can be separated from the grating panel 1 through a demoulding device 70 . The demoulding device 70 includes a supporting frame 71 , a screw rod 72 and a connecting piece 73 . The support frame 71 is configured to stably place the demoulding device 70 on the metal grid plate 1 . In one embodiment, the support frame 71 includes two legs 74 and a support body 75 , and the two legs 74 are respectively connected to two ends of the support body 75 . After the demoulding device 70 is placed on the second surface 12 of the overturned grid plate 1, the extension direction of the support body 75 is parallel to the second surface 12 of the grid plate 1, and the feet 74 are against the pre-installed The second surface 12 of the cast grating panel 1 . The substantial center of the supporting body 75 has a threaded hole 751 passing therethrough.

Specifically, the combination member 73 includes a disc structure 730 . The diameter of the disc-shaped structure 730 can be selected such that the disc-shaped structure 730 can protrude into the interior of the mold 90 and engage the longitudinal rib 93 . A peripheral edge of the disc structure 730 has a plurality of grooves 731 , and the grooves 731 have a width allowing the longitudinal ribs 93 to pass through. In addition, the combination member 73 includes a plurality of positioning grooves 76 formed on the disc structure 730 and arranged alternately with the grooves 731 along the periphery of the disc structure 730 . In one embodiment, the number of grooves 731 and the number of positioning grooves 76 are equal to the number of longitudinal ribs 93 of the mold 90 , but the invention is not limited thereto. The number of the grooves 731 or the number of the positioning grooves 76 may be greater than the number of the longitudinal ribs 93 of the mold 90 to facilitate the engagement of the mold 90 with the longitudinal ribs 93 .

As shown in FIG. 8 , the above steps further include: putting the combination part 73 of the demoulding device 70 into the mold 90 , wherein the disc structure 730 enters the mold 90 at a first predetermined angle. At the above-mentioned first predetermined angle, the position of the groove 731 is relative to the position of the longitudinal rib 93 of the mold 90, so that when the disc-shaped structure 730 enters the process of the mold 90, the longitudinal rib 93 passes through the groove 731, so that the disc-shaped structure 730 reaches below the longitudinal rib 93 .

As shown in FIG. 9 , the above steps further include rotating the coupling member 73 to a second predetermined angle. At the above-mentioned second predetermined angle, the positioning groove 76 is located below the longitudinal rib 93 and engages with the longitudinal rib 93 . In one embodiment, the screw 72 engages with a nut at the center of the combination part 73 after the combination part 73 is put into the mold 90 to jointly form a picking mechanism. In addition, during the operation of the combination member 73 rotating from the first predetermined angle to the second predetermined angle, the combination member 73 rotates together with the screw rod 72 . Therefore, when the coupling part 73 rotates, the coupling part 73 will simultaneously move in the vertical direction, thereby completing the engagement between the positioning groove 76 and the longitudinal rib 93 .

As shown in Figure 10, after the coupling part 73 is engaged in the mold 90, a drive is started A mechanism 77 (eg, a rotary actuator or an electric torque wrench) separates the mold 90 from the metal grid plate 1 and exposes the perforations 13 . In one embodiment, before the driving mechanism 77 is activated, the driving mechanism 77 is connected to the opposite end of the threaded rod 72 to the end of the joint 73 . In this way, as shown in FIG. 11 , after the driving mechanism 77 is started, the driving mechanism 77 rotates the screw 72, and makes the screw 72 move linearly relative to the support frame 71, and then the mold 90 is separated from the metal grid plate 1 and exposed. perforation13.

In one embodiment, the above steps can be repeated to use the same demoulding device 70 to separate all the molds 90 from the 預鑄 Lattice panel 1 and expose all the perforations 13 , so as to complete the production of the 預鑄 Lattice panel 1 .

Please refer to FIG. 12 , this embodiment can provide a backfill 100 to seal the top of the through hole 13 . In this embodiment, the through hole 13 has at least one stop contour 131 formed on the inner peripheral surface 134 of the through hole 13 , and its shape may include extending along the inner peripheral surface 134 of the through hole 13 . At least one protrusion protruding radially inward. However, the quantity and type of the stopper contour 131 are not limited in this creation, and the stopper contour 131 can also be more than two above-mentioned protrusions, or it can be an annular diameter along the inner peripheral surface 134 of the through hole 13. An annular flange extending toward.

In this embodiment, the lower peripheral edge of the backfill plug 100 has a complementary profile 102 which is complementary to the stop profile 131 of the through hole 13 , eg the lower peripheral edge of the backfill plug 100 shown in FIG. 3 . The complementary profile 102 can be, for example, a notch complementary to at least one protrusion protruding radially inward on the inner peripheral surface 134 of the through hole 13 . Similarly, the number and type of complementary contours 102 are not limited in this creation, and it may also be more than two above-mentioned notches, or may be an annular notch extending along the peripheral direction of the lower peripheral edge of the backfill plug 100 .

Although the present invention does not have any restrictions on the height of the backfill plug in the thickness direction (or height direction) of the grid plate 1, yet because the backfill plug 100 is backfilled in the through hole 13 , it will be stopped by the stop profile 131 of the through hole 13 to limit its further movement, so that the upper surface 101 of the backfill plug 100 can be flush with the first surface 11 of the metal grid plate 1, so the height of the backfill plug 100 will be The position of the stop contour 131 is restricted on the inner peripheral surface 134 of the through-opening 13 .

In other words, due to the above-mentioned configurations of the through hole and the backfill plug, when the backfill plug 100 is inserted into the through hole 13 from above the metal grid plate 1 along the axial direction of the through hole 13, it is subject to the at least one stop profile. 131 stops at least one stop contour 131, and the backfill plug 100 has a height h1 (see FIG. 12 ) so that when the backfill plug 100 is backfilled and stopped at the stop contour 131 of the through hole 13, The upper surface 101 of the backfill plug 100 is flush with the first surface 11 of the grating 1 , and this process is shown in FIG. 13 . In addition, since large equipment needs to be arranged above the backfill plug 100, the backfill plug 100 can have a certain height (or thickness), for example, its height (or thickness) is at least one-fifth of the depth of the through hole 13 (ie h1>1/ 5H). In one embodiment, its height (or thickness) can be between one-fifth and one-third of the depth of the through hole 13 (ie, 1/3H>h1>1/5H), which can provide sufficient support It is also unlikely to excessively waste the use of the backfill plug 100 material.
