Detailed Description
The structure of the present invention will be further explained with reference to the accompanying drawings, and the description herein is for the purpose of explaining the present invention and using the new patent, and is not intended to be limiting. The utility model discloses a novel patent aims at solving sleeve kind singleness, the low problem of machining efficiency, develops a brand-new pre-buried sleeve of adjustable bearing capacity size.
As shown in fig. 2, a pre-embedded sleeve assembly 100 with adjustable bearing capacity comprises an internal thread part 2 for connecting a hoisting tool 6 and a threaded rod part 3 for connecting a connecting plate 4, wherein the threaded rod part 3 and the internal thread part 2 are in meshed relation with each other so as to connect a plurality of pre-embedded sleeve assemblies 100 to each other according to needs. Therefore, in practical use, the embedded sleeve fittings 100 are connected and extended when bearing capacity needs to be increased, so that the purpose of regulating and controlling the bearing capacity is achieved. On one hand, the processing cost is reduced, and on the other hand, the selectivity is increased in field use. The internally threaded portion may also be referred to as a threaded bore, a bore with internal threads, or the like.
The sleeve is made of high-quality carbon steel, nodular cast iron materials or HRB 400-grade steel bars, threads on the top cavity and the bottom of the cylinder body can be automatically formed by machinery, continuous production of the sleeve is realized, and the length of the sleeve directly influences the bearing capacity of the prefabricated part. Meanwhile, the connecting plate at the bottom of the sleeve can be selected and matched according to the stress, so that the bearing capacity requirement can be met, and the cost can be saved. In a preferred embodiment of the present invention, the connecting plate 4 can be made into two parts: the cylinder part and the disc part can be selected from different disc parts according to the requirement of the contact area.
The internally threaded portion 2 and the threaded shank portion 3 are connected linearly or at an angle by an intermediate portion as shown in fig. 1. The figures do not show an angled connection, but the person skilled in the art will readily understand that the threaded shank portion 3 can be arranged laterally in the concrete, keeping the threaded bore portion 2 vertically upwards. Such an arrangement is advantageous where the preform is small in thickness but large in width.
In the drawings, the intermediate portion is formed integrally with the internally threaded portion and the threaded shank portion. As is readily known in the art, the described construction of the pre-buried sleeve assembly 100 can be achieved by machining on a cylindrical barrel.
As shown in fig. 2, a connection plate 4 is further included, and the connection plate 4 includes a circular disk (a large circular portion in a plan view) for increasing a contact area with concrete. The web 4 has an internal thread in threaded engagement with the shank portion 3.
Another preferred embodiment of the present invention is that the pre-embedded sleeve assembly 100 is one of the pre-embedded sleeve assembly groups which are set to have a series of lengths according to different bearing capacities, so as to select the corresponding specific pre-embedded sleeve assembly according to actual needs.
As shown in fig. 4, another preferred embodiment of the present invention also relates to a prefabricated member comprising a pre-embedded sleeve fitting according to the above-mentioned adjustable bearing capacity, which is connected by means of a hoisting tool 6 for demoulding, transport and installation.
When the sleeve is used, referring to the attached figure 4, the embedded sleeve is embedded into the concrete 7, after the strength of the concrete 7 reaches a designed value, a hoisting tool 6 is screwed in along the top of the embedded sleeve, and then a steel wire rope (not shown in the figure) is fixed on the hoisting tool 6 to complete the processes of component demoulding, transferring, installing and the like; when the device is used for hanging heavy objects, the heavy objects or the bridge frame for fixing the heavy objects can be directly fixed on the embedded sleeve by bolts.
The above embodiments are set forth so that they will be understood by those skilled in the art from a reading of the present invention, and not by limitation, as the scope of the present invention will be defined by the appended claims.
