Description

Steel die arrangement for moulding a lattice structure and method of manufacturing a lattice structure with chamfers

Technical Field

The present disclosure relates to a steel die apparatus for molding a lattice structure and a method of manufacturing a lattice structure having chamfers.

Background

Because the application range of the semiconductor is wide, the demand is increasing day by day, the indirect influence is achieved, and the demand for building semiconductor plants is increasing. The amount of dust around the semiconductor during the manufacturing process needs to be strictly controlled so as not to damage the precision and reliability of the product. The construction of a clean room by using a lattice beam perforated floor (lattice plate) is to discharge dust out of the clean room through the lattice plate perforations by using positive pressure and to re-enter clean air containers into the clean room through filtered return air, and is a design mode commonly used in semiconductor factories at present.

In the process of pouring and curing concrete to form the grid plate, a steel plate module for molding the grid plate is often extruded and deformed due to lateral pressure generated by the weight and the slump flow characteristic of the concrete, so that the grid plate manufactured by the cured concrete is also deformed, particularly, the corresponding steel die in the middle section area of each side edge of the grid plate is easy to generate a side surface which is slightly arc-shaped and uneven after forming due to insufficient supporting force, and the installation and pouring space of beams among different grid plates is influenced or compressed. In addition, the edges of the conventional grid plates have sharp right-angle edges, so that the right-angle edges are easy to crack due to collision in the process of carrying the grid plates subsequently, and the cracks possibly spread to the inside of the grid plates so as to damage the internal structures of the grid plates.

Based on the above problems of the conventional technology, there is a need in the industry for a steel mold device capable of forming a grid plate with a flat side surface, and a method for forming a proper chamfer on the edge of the grid plate by using the steel mold device.

Detailed Description

Embodiments of the present disclosure, including various embodiments, will be described in detail below with reference to the drawings. It should be noted that the contents of the embodiments of the present application are only for illustrating one specific aspect of the present disclosure, and do not limit the scope of the present disclosure.

Figure 1 shows a schematic view of a lattice structure formed via the steel die apparatus of the present disclosure. The lattice plate structure 1 includes concrete 13 and a plurality of longitudinally and transversely staggered reinforcement cages disposed in the concrete 13, and the lattice plate structure 1 is formed with a plurality of lattice plate holes 19 therein through a mold. The clean room of the high-tech factory building with the grid structure 1 is then evacuated by positive pressure through the grid holes 19 of the grid beams and cleaned air is re-admitted into the clean room by filtered return air. The side 15 of the grid plate structure 1 is protruded with a reinforcement connection structure 11 formed by the end of the reinforcement cage extending outward, and the reinforcement connection structure 11 is used to connect with the post-installed beam and/or column, so as to be installed smoothly and quickly as the roof or floor of the factory building. As can be seen in fig. 1, the grid plate structure 1 molded from the steel die assembly of the present disclosure has flat peripheral sides 15 with appropriate chamfers 17 on the peripheral edges.

Fig. 2 shows a schematic view of the disclosed steel die apparatus, and fig. 3 shows a schematic partial cross-sectional view of the disclosed steel die apparatus. Please refer to fig. 1 to 3 together.

The present disclosure provides a steel mould device 3 for moulding a lattice structure 1 having a peripheral side 15 which is flat and substantially perpendicular to the ground, and having a suitable chamfer 17 on the upper edge of the peripheral side 15. The grid plate structure 1 shown in fig. 2 and 3 is in a state where the concrete 13 has not been completely cured and the steel die assembly 3 has not been removed, so as to facilitate the description of the relative position between the steel die assembly 3 and the grid plate structure 1. The method of manufacturing the lattice structure 1 formed by the steel mould arrangement 3 of the present disclosure will be described in detail in another paragraph later.

As shown in fig. 2 and 3, the die unit 3 includes a plurality of dies 31, a plurality of fasteners 35, and a plurality of auxiliary devices 33. The steel molds 31 are used to support and mold the uncured grid plate structure 1, and the steel molds 31 are disposed on two sides of each steel bar connecting structure 11 and surround the peripheral side surfaces 15 of the grid plate structure 1. Each die 31 has a top surface 311 and has a hole 313 therein for receiving a corresponding fastener 35.

The auxiliary devices 33 are arranged around the grid plate structure 1 and substantially aligned with each other along each circumferential surface of the grid plate structure 1. Each of the auxiliary devices 33 has a flat bottom 339, and the flat bottom 339 is engaged with the top surface 311 of the corresponding steel mold 31. In addition, each auxiliary device 33 has a through hole 331 corresponding to the hole 313 of the steel die 31. In detail, the fasteners 35 are respectively inserted through the through holes 331 of the auxiliary devices 33 and fixed in the holes 313 of the steel dies 31, whereby each auxiliary device 33 laterally bridges the top surfaces 311 of the adjacent steel dies 31. This lateral bridging aid 33 allows the strength of the connection between the steel dies 31 to be increased. Meanwhile, during the pouring or curing process of the concrete 13, the steel mold 31 will not deform or expand outward due to the lateral pressure generated by the weight and the slump flow characteristic of the concrete 13, so that the steel mold device 3 can provide sufficient lateral support during the curing process of the lattice plate structure 1, thereby manufacturing the lattice plate structure 1 with the smooth peripheral side surfaces 15.

Each auxiliary device 33 is a substantially rectangular steel plate with a width W of 20 cm and an overall thickness T of 2-3 cm, however, the size of the auxiliary device 33 can be adjusted according to the size of different steel dies, and in another embodiment, a plurality of auxiliary devices 33 are designed to be integrally formed. As shown in fig. 2 and 3, each auxiliary device 33 comprises an inclined surface 333 arranged towards the grid structure 1 and inclined towards the inside from top to bottom for forming a chamfer 17 at the corresponding corner of the grid structure 1 after the formation of the grid structure 1. Each auxiliary device 33 comprises a first flat upper surface 335 adjacent to the grid structure 1, the first flat upper surface 335 forming an angle θ 2 of about 45 degrees with the inclined surface 333.

As shown in fig. 2 and 3, the first planar upper surface 335 of each ancillary device 33 is substantially flush with the top of the grid panel structure 1. Each auxiliary device 33 comprises a second flat upper surface 337 at the opposite side of the grid plate structure 1, the second flat upper surface 337 being adjacent to and lower than the first flat upper surface 335. The perforation 331 of each auxiliary device 33 is disposed in the second planar upper surface 337, and the top of the fastener 35 located in the perforation 331 is substantially flush with or slightly lower than the first planar upper surface 335.

The above arrangement may provide benefits for the subsequent glazing of the grid structure 1, in particular, the top surface 132 of the concrete 13 immediately after casting is uneven, and in order to level the top surface 132 of the concrete 13 after casting, a glazing machine (or a screed, a troweling machine, etc.) is generally used to integrally glaze the top surface 132 of the concrete 13, so as to level the top surface 132, and to provide a smooth surface without cracking in the future of the grid structure 1. The flush design of the concrete 13 and the auxiliary device 33 of the present disclosure enables the troweling machine to smoothly operate on the top surface 132 of the concrete 13 without being hindered by any protrusion or interference, and completely finish the troweling operation of the concrete 13 near the auxiliary device 33. In addition, the flush or slightly lower design of the fastener 35 relative to the first planar upper surface 335 avoids the sander from colliding with the fastener 35 during the sanding operation.

In the embodiment, the fastening members 35 are bolts, and corresponding threads are provided in the through holes 331 of each auxiliary device 33 and/or the holes 313 on the top of each steel mold 31, so as to achieve a firm connection between the auxiliary device 33 and the steel mold 31. In another embodiment, the fastener 35 is a rivet, and the auxiliary device 33 is fixed in the hole 313 at the top of the steel die 31 by using the deformation of the rivet after striking.

In another embodiment, the steel mold device 3 further has a base (not shown) which forms a complete concrete placement space together with the steel mold 31. For the details of the substrate, the technical contents of taiwan patent publication No. I277498, and particularly the technical features of the bottom mold described in said patent, are incorporated herein by reference, and are not repeated herein.

As shown in figure 2 the die assembly 3 further comprises a plurality of elongate stiffening structures 37 respectively located on the outside of the dies 31 on each side of the grid structure 1 and bridging the dies 31, the elongate stiffening structures 37 being interconnected to provide lateral support to the dies 31 against the outwardly pushing pressure generated by the grid structure 1 during the forming process. In more detail, the elongated stiffener structure 37 is disposed on and bridges the base extending outward from the bottom of the steel die 31, thereby providing sufficient strength for the steel die 31 to be less likely to deform.

To mold a grid plate structure 1 as in fig. 1, the present disclosure further provides a method of manufacturing a grid plate having flat sides 15 and appropriate chamfers 17. When reading the following description of the manufacturing method, please refer to the names and symbols of the elements described in FIGS. 1-3.

5. And lubricating oil is coated on the inner side of the steel die device 3, so that the steel die device 3 can be removed after the concrete is solidified.

6. Rubber strips or sheets (not shown) are adhered to the gap between the steel form 31 and the steel bar connecting structure 11 to prevent the concrete 13 from overflowing in a large amount during the subsequent pouring operation.

Thirdly, step three: concrete 13 required for casting the lattice structure 1.

The concrete 13 is poured into the concrete placing space, and waiting for the concrete 13 to reach a predetermined strength.
