Detailed description of the invention
Below embodiment of the present utility model is elaborated:
As shown in Figure 1, embedded part at the bottom of a kind of clear-water concrete plate, it,, for the fixing hanging object with external connecting rod 100, comprises vertical rod 10, at least three support bars 12; Described external connecting rod 100 is provided with screw thread, and described vertical rod 10 includes link 102, and link 102 is provided with the screw thread with the threaded engagement of described external connecting rod 100, by the fixing mode of screw thread, external connecting rod 100 is fixing with vertical rod 10; Described in each root, one end of support bar 12 is all fixedly connected with described vertical rod 10, and the angle between any two described support bars is greater than 0 degree and is less than 180 degree, many support bars 12 form several triangular support structure to vertical rod 10, vertical rod 10 can be stablized fixing.
Described external connecting rod 100 is for hanging the syndeton of hanging thing, by being connected and fixed of described external connecting rod 100 and embedded part at the bottom of clear-water concrete plate, extension being hung to thing and be fixed on the metope or ceiling that clear-water concrete makes.
By fixing to one end of support bar 12 and vertical rod 10, thereby by support bar 12, described vertical rod 10 is supported, any two support bars 12 all form triangular support structure, adding after clear-water concrete 200, increase the bond stress of embedded part and clear-water concrete at the bottom of this clear-water concrete plate, improved the bonding strength of embedded part and external connecting rod 100 at the bottom of this clear-water concrete plate.Also avoid on the other hand carrying out in the work progresss such as reinforcing bar binding, correction, concreting, at the bottom of this clear-water concrete plate, embedded part can not be shifted because affected by external force, is applicable to the cooperation of various templates, and at the bottom of plate, embedded part is arranged more flexible, power transmission more evenly, rationally, practical.The external connecting rod 100 of hanging object is fixedly connected with by the mode of screw thread with vertical rod 10, and fixed form is simple, convenient, easy to operate.After clear-water concrete form removal, vertical rod 10 is little with the pin point of support bar 12 and the contact area of clear-water concrete, can be blocked by the primary colors of clear-water concrete, guarantees clear-water concrete surfacing, and gloss is consistent, increases its aesthetic property, expands range of application.
The end (pin point) of the other end of described support bar 12 is hemispherical or pointed shape, guaranteeing on the basis of the support strength of support bar 12 to vertical rod 10, the pin point of described support bar 12 dwindles as much as possible, reduces the contact area of itself and clear-water concrete.
Described vertical rod 10 is hollow stem, and the link of hollow stem is provided with internal thread, other end sealing, and the external screw thread of the internal thread of its link 102 and external connecting rod 100 is fixed hanging object; Preferred described vertical rod 10 vertically arranges.At the bottom of described clear-water concrete plate, embedded part also comprises threaded protective cap 14, and before building clear-water concrete, described protective cap 14 is placed on the link of described vertical rod 10, and the vertical rod 10 of hollow is sealed, and avoids foreign material to enter in vertical rod 10; In the time that needs are applied, the protective cap 14 at dismounting link 102 places, external connecting rod 100 can by on-the-spot Che Sihou directly and vertical rod 10 fix.
The material of described vertical rod 10 and described support bar 12 is steel, makes full use of the tensile strength of steel, meets installation and the service requirement of suspension equipment.The material of described protective cap 14 is timber or steel, and the color of capable of regulating protective cap 14 is guaranteed the outward appearance uniformity of clear-water concrete.
The present embodiment preferably arranges three described support bars 12, and the angle between adjacent two support bars 12 is 60 degree, and adjacent two support bars 12 form isosceles triangle braced structures, makes vertical rod 10 be subject to equal power and supports.
Another embodiment of the present utility model, different from above-described embodiment is, the radical of described support bar 12 is at least the six roots of sensation, at least four support bars 12 are the first support bar 122, described the first support bar 122 is distributed in the periphery of described vertical rod 10, at least two described support bars 12 are the second support bar 124, described the second support bar 124 and described vertical rod 10 intersect fixing after its two ends fixing with described the first support bar 122 respectively again, support bar 12 described in each root is directly or indirectly connected with described vertical rod 10, vertical rod 10 is implemented to support force.The end, lower end (pin point) that wherein, described the first support bar 122 can be preferably only set is hemispherical or pointed shape.
Preferred embodiment includes six roots of sensation support bar 12, and wherein four is that 122, two of the first support bars are the second support bar 124.The mode that two described the second support bars 124 are preferably right-angled intersection is fixed.
The above embodiment has only expressed detailed description of the invention of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
