20 Supports or spacers are often used by the construction industry to support and position steel reinforcement members such as steel cables and/or steel bars at a suitable distance above a surface. The reinforcing bars are usually arranged in columns or grids in an area where the concrete is to be poured, and loosely held in position as the concrete is poured into its surroundings. In conventional use, a receiving area formed on the support base contacts and supports the steel ribs while the base of the support base is placed on a floor or a foundation. The correct spacing and arrangement of steel reinforcement members in concrete slabs in accordance with known design and construction specifications can have a significant impact on the structural strength and integrity of the concrete structures. These steel reinforcements need to be fully covered (4) to avoid the impact of moisture on the wet weather. When the steel is exposed to moisture containing chemicals, the corrosion begins. The conventional support seat has the seam feature and the desired feature of the steel bar or the rear pull cable which is safely and properly supported by the concrete knot. For example, the award is given to the number of 5,729,949 faces that are easy to stack and the empty cone body is made to minimize the amount of necessary transportation. These 5 200831754 have legs and have holes between the legs to allow concrete It flows into the hollow interior of the support. Workers can carry multiple support seats at a time and place many support seats at a worksite without repeatedly going to the storage area. 5 10 15

The tapered shape of the support also requires that the upper portion of the body 1 (including the receiving portion 14 in the inner J is substantially narrower than the portion containing the lower portion of the wider base 12). The rib 2 is used to separate the stacked seats. The support base is easy to separate. 5

The apertures 36 between the legs 15 and 32 are preferably arched and allow the fluid concrete to pass through the body 1 () below the elevation of the receiving portion 14. The void % provides 幵 = the free flow of the concrete flow support 8 and its surroundings is maximized: the acoustic foot 32 preferably has a thick strip of material 40 around the aperture 36, resulting in a reinforcement 2 allowing the legs 32 feet As shown, the base 12 has a four-legged member 34, and both of them contain a member 34 that extends horizontally therefrom. The leg has no such foot member. In Fig. 1, the foot members project only from the oppositely extending legs 32 of each other. Figure 2 shows that the reinforcing members % and % are supported by the figure. The reinforcing members 38 and 39 meet each other in the center 14 including the inside. The receiving area pairs 24h, the spear-to-curve recesses 24a and 24b, wherein the first pair 24b is oriented to the first, and the second brother - including from the outer surface π 4 to 2, such as ninety degrees apart. The notches 24a, 24b 24a = a curved bearing surface extending inward. The first-to-nozzle 深 receives the deep recess t of the reinforced member. The recess receives the reinforced member 39.

Too discerning 1Λ w 』 The end of the 4 4 is gradually widened by two 7 two and two 26 to the foot 32. ^ 4 opening Μ so its circumference is much larger than the receipt of £ 4. Again, the female foot % is from the - joint 26 in a straight line down: into. Preferably, both of the legs 32 have a = member 34' for the bottom ride to provide a more advanced step support effect such that the base pole k is supported by the support base 8 and the weight of the reinforcing member. 3 examples show another - the reading of the viewpoint, wherein the base n2 includes - the foot I32 and the upper leg m. The lower leg m is the main leg and is larger and longer than the upper leg 133. The receiving zone 114 is supported by both the upper and lower legs 132, 133, wherein the upper leg 133 extends downwardly from the receiving zone 114 and defines an upper aperture 137 'the lower leg I% extends from the upper leg 133, down and bounds The aperture 136 is punched. The projection 142 defines the junction of the upper leg 133 and the lower leg 132 fe1 and extends from the periphery of the surrounding body 110 as seen. As shown in Figure 3, the base 112 has four lower legs 132, both of which further include a foot member 134 extending horizontally therefrom, the other two legs having no foot members. The foot member 134 is diametrically opposed to the opposite lower leg 132 (four). The upwardly extending ribs 120 are disposed on the outer surface 12 200831754 face 11 8 and are used as spacers to separate the stacked support seats, as described above with respect to the ribs 20 of Figures 1 and 2.

The lower and upper apertures 136, 137 between the lower and upper legs 132, 133 are preferably arched and allow fluid concrete to flow through the body 110 below the stroke of the receiving region 114. The large openings provided by the apertures 136, 137 maximize the free flow of concrete into the support seats 1 and 8 and its surroundings. The lower leg 132 preferably has a thick strip of material 14 around the lower aperture 136 such that the strength of the support is enhanced by the thickened regions 14 to allow the lower leg 132 to be made longer while still retaining its strength. The receiving zone 114 shown in Figure 3 is similar to the receiving zone 14 shown in Figures 2 and 2 and is adapted to receive and support concrete reinforcing members or reinforcing bars. The inner surface ι6 of the base 112 and the receiving area 114 is complementary to the outer surface 118. The main body ι has a plurality of straight sides and is substantially tapered, and the lower opening 122 is larger than the receiving area 114' thereby allowing a plurality of supports to be pure Stacked for storage and transportation, the 'stackable branch (10) is easy to move in a workplace, so that it is possible for a person to carry the stack of support (10) with one hand and to remove the individual support from the stack The desired location of the workplace. The receiving area 114 of Fig. 3 further includes a plurality of bridge members 128. The bridge members are connected to the two bridge members 128 at the junction of the (four) 114 towels. The bridge member 12 is connected to the middlemost lower portion (or groove portion) of the recess 124 and spans the distance between the recesses 2 and 4 in the support base body m; however, although the bridge member is shown at: two; one of the seats 1 〇 8 is an optional component . The bridge member 128 assists in supporting the support of the base 8. The optional bridge member is used to support the reinforcing members 138 and 13 20 200831754 139 of the support base body 11 , and to add strength and support to the structure. The apertures are shown in generally Chess shape in Figures 1 through 3, but it will be understood by those skilled in the art that there are many shapes of apertures available. The feet are usually of sufficient width and strength to support the essence = the force of the reinforcing members and the forces exerted by the construction workers on the reinforcing members during construction. Surrounding; == The strip adds strength to the structure, so that the branch will not collapse here. Each foot member allows the base to be placed on a flat lining floor = or a soft plane such as dirt, sand; or the like: the support is stacked as shown in Figure 4, the plurality of support seats % and 8 are inside. The combination of the donor's garment in the cone-shaped, roughly funnel-shaped shape of the other seats 8a and 8b is $15 20 on the eve of the table. The slidably joined to the second branch ==:: The first support can be inserted into the second The distance from the receiving zone 14 in the support to the surface 16 of the lower core 22 and Ζ 2 means that the slope of the junction (4) relative to the lower opening 22 = 2 Γ: 18 will be greater. Preferably, most of the slope support is inserted into the second support, so that the large sc is in a very small space without the pile being supported as described above. The support _ is stacked in a similar manner - the foot member & the opposite leg 14 200831754 where the kitchen-supporting red foot member is located, or the foot member can be on the same corresponding leg, enabling the user to confirm that one of the support seats is specific Corner. It should be understood that this stacking capability allows a worker to carry a stack of support seats while the support is placed in the workplace. Referring now to Figure 6, a plurality of support seats 208 similar to those shown in Figure 3 can be formed by combining a base 212 with an adaptive receiving area 214. The base 212 can be substantially identical to the base 112 described above, and similar structures are used to indicate similar structures, such as the lower leg 232 and the upper leg 233. The base 212 may also be substantially identical to the base 12 described above, with the associated feature that the base portion or body of the support base 208 is substantially identical in size and design. The adaptive receiving area 214 can include four vertical fins 250 that define a first open pair 224a and a second pair 22 of opposing open recesses: The term 'vertical fins' as used herein shall be interpreted as a vertically directed structure having a uniform lateral extent and comprising structures providing a stepped and/or progressively enlarged cavity defined within such ranges. The term "opening recess" as used herein shall be interpreted as the space directly above the entire feature of the notch, such as overhangs, shackles or other obstructing bars, rear pull cables and the like moving vertically away from the recess. Obstacles to the device. The inner surface 216 of the base 212 is generally complementary to the outer surface 218, and the lower opening 222 is larger than the receiving area 214, thereby allowing the plurality of support seats to be stacked in a manner that is primarily loaded into the other for storage and transportation. The vertical fins 250 separate the stacked support seats and facilitate the separation of the support seats so that the ribs 2, 12 can be omitted. The first pair of notches 224a and the second pair of notches 22'' are oriented at ninety degrees to each other, with the lowermost portion of the first pair of notches 224a being positioned at a portion of 15 200831754 than the second pair of notches 224b Low height. Therefore, the single-seat 208 can support the steel bars at different heights and are perpendicular to each other. For example, the support base 208 can support a single part of the steel bar in a raft.

20 One of the two heights above, such as 5.25 inches or 5. 5 inches above the foundation, or to support a steel mesh in an overlapping vertical relationship, such as ground = upper 5 · 25 inches and 5.5 inches. ^ The receiving areas 214 of the plurality of support seats 208 are adjustable so that the different support seats 208 can provide support at different heights above a support surface = still be fabricated using a single-molding device. The receiving area is modified by modifying the height of the wrong Korean film 250 to change the degree of the lowermost portion of the notch 224. For example, a second support seat 2〇8 having a longer vertical fin 25〇 and an intrinsic phase base 212 can support a single portion of the reinforcing bar at one of two heights above the support surface, such as above the foundation 5 75 two inches or = inch time 'causes to make two slightly different support seats =, = the same height - four different heights above the support surface for the steel bars to provide support for the use of two. The length of the sheet of 25° allows the supplier to build a production line of these different building blocks using the early-molding device. In the above view, the 'per-straight fin 25() is preferably one. The vertical 225 is strengthened. This gusset protrudes from the wrong Korean film 250 and goes upwards to define the relevant lower part in the middle. The angle is 2 2 2 2, listen to the support of m #, prevent # Lateral deformation and regional collapse occur due to the fact that the recess is too small, the ribs, the rear cable and the like. The length of the gusset 252 can also be modified to permit the use of a single i molding 16 200831754 device to produce different Support stand. Figure 7 illustrates another view of the support base 308, which consists of a four leg 3 The generally cross-shaped body 310 of 32 is combined with an adaptive receiving area 314. The two opposing legs 332 can be constructed to extend from a vertical fin 35 〇 laterally downwardly to define an open recess 324. The other two opposing legs 332 can be constructed to project laterally downwardly from a pair of opposing gussets 352 that project perpendicularly from the vertical fins 35. The gussets 352 extend upwardly to further define the recesses. The lowermost portion of the middle portion of 324, and the support strength of the staggered fins is increased. The equal angle plate 352 can also re-direct the weight of the steel bar by reducing the tendency of the steel bar to hook to the edge of the open recess 324 The anti-dumping capability is provided by the portion of the support 308 that tends to rotate upward due to the longitudinal movement of the reinforcing bar. Figure 8 illustrates another aspect of the support base 408 that incorporates a body 41 and an adaptive receiving area 414. The body 410 There are a plurality of legs 432 extending downward from the receiving area 414. Each leg 432 is coupled to the adjacent leg 432 by a horizontal brace 444, and the horizontal brace 444 collectively forms a closed geometric hoop 446 to prevent Feet 432 Or open. Adjacent legs 432 define apertures or apertures 436 that allow the poured concrete to flow through support 408. Legs 432 may also have a thick strip of material around each aperture 436 such that legs 432 have a τ-shaped or cruciform profile (not shown). The legs 432 and the horizontal struts 444 jointly define a lower opening 422. The body 410 is generally tapered, with the lower opening 422 being larger than the receiving area 414, thereby allowing multiple supports The blocks are stacked in a manner that one is stacked on top of the other. 0 17 200831754 450 and - private inclusion - staggered fins defining an open recess 424 5 10 15

20 452. The gusset is 45 Γ. The opposing gussets of the sheet 450 projecting vertically upwardly extend from the upper side to further define the notch 424 j to remove the cymbal. The gusset 452 increases the strength of the support of the vertical fins, minus: the tendency of the steel bars to the edge of the open recess 424: redirecting the weight to a support Iton that has a tendency to lose the day due to the longitudinal movement of the steel bars Partially provides anti-dumping ability. Specifically, Figure 8 is not structured, and both of the opposing legs 432 may be protrusions extending laterally downward from the wrong tab. And the other two opposing legs 432 can be protrusions that extend laterally downward from the gusset 452. In various aspects such as the above, when the plurality of support seats are stacked together, the interference between the legs 432 of one support seat 408 and the second support base 4 (the collar 446 of the ^) substantially limits the second support The horizontal movement of the bottom of the seat 408. The efficiency of such stacking may vary depending on the length of the vertical fins 45〇, but still permits storage and transportation in a reduced volume, and still permits the worker to carry multiple supports at the site at a time. As mentioned earlier, modifying the length of the vertical fins 25〇, 35〇, 45〇 allows the supplier to build a production line that supports the support at different heights using a single molding device. Referring now to Figure 9, The mold 5 can be formed, shaped or otherwise formed to provide a basic configuration having a support base (such as support 208), the configuration including the bodies 21, 310, 410 and the receiving area 214, 3M, 414 but does not contain any of the vertical fins 250, 350, 450 originally included in the receiving area. The mold may further comprise or be subsequently modified to include a cross section having a corresponding height of the first vertical fin 18 200831754 250 horizontal A first channel surface 510, a second error corresponding to the straight fin (fin of this case have) said second alignment channel 510 cross-sectional surface of the subject, and the like.

20 The mold may also include a first adjustable blade 520 having a cross section corresponding to a cross section of the first staggered fin 250, and a cross section corresponding to the second staggered fin (in the case of the fin) The second adjustable blade 520 of the cross section, and the like. Each of the adjustable vanes 520 can be fully inserted into its corresponding channel 510 such that the insertion end 525 of the vane 520 defines a top surface of the recess in the receiving seat receiving area. Each of the adjustable vanes 520 may also partially withdraw into its corresponding channel 510 such that material can enter the channel 510 to form a staggered fin 250'. The notch in the staggered fin 250 is defined by the insertion end 525 of the vane 520. The top surface of 224. By adjusting the insertion of each blade 52, the supplier can adjust the length of the vertical fins 250, 350, 450 in a support to produce a plurality of supports at different heights above the support surface using a single molding apparatus. Support seat. In the view of the gussets 252, 352, 452, the mold may include a channel 510 and a blade having a cross section corresponding to one of the staggered fins 25, 350, 450 and the associated gussets 252, 352, 452. 520. The insertion of the cake 525 will thus further define the top surface of the associated gussets 252, 352, 452 and preferably further define the structure associated with the lowermost portion of the recesses 224, 324, 424. t, the support that can be revealed by the Ming can be made more than most of the conventional support seats, and is lightweight but still strong enough to firmly support the steel bars, and the weight of the stomach collapses. Preferably, the support base is preferably made of 19 200831754. The material of the material is made of a plastic or tree. The head piece is replaced by a 'supporting seat'. It is placed on the top of a basic support base and is made up of a monolithic polymer material.
