Abstract
The utility model relates to a lifting device, in particular to a pre-buried lifting device for a fireproof material prefabricated member. The pre-buried lifting device comprises lifting bolts and also comprises a pre-buried metal frame and at least two parallel arrayed pre-buried metal pipes, wherein metal holes for enabling the pre-buried metal frame to penetrate through are formed in the pre-buried metal pipes; anchoring nails are welded at the lower ends of the pre-buried metal pipes; internal threads are formed on the pipe walls of the upper ends of the pre-buried metal pipes and are matched with threads on the lifting bolts; the pre-buried metal pipes and the metal frame are arranged in a prefabricated member mill; the upper end faces of the pre-buried metal pipes are flush with the upper surface of the prefabricated member. The utility model discloses the pre-buried lifting device for the prefabricated member, which is simple in structure and convenient to mount and can meet requirements on lifting for multiple times and assembling for multiple times.
Description
Technical field
The utility model relates to a kind of boom hoisting, is specifically related to the pre-buried boom hoisting of a kind of fireproofing prefabricated member.
Background technology
In the industrial departments such as metallurgy, chemical industry, machine-building, often to adopt high temperature kiln to process various materials, in general, thermal kiln furnace is all on-the-spot formwork cast or field by using laying fireproof bricks, construction period is long, after construction, also need to toast for a long time, cause Project design construction period long.Field condition is relied on during site operation highlyer, kiln construction quality is subject to the various factors such as Construction control, quality of materials, maintenance baking, is unfavorable for the control of kiln masonry quality simultaneously.High temperature kiln design specification is generally larger, often can be because local damage cause kiln production efficiency low after construction, and repairing efficiency is long simultaneously, and scheduling of production is caused to a lot of inconvenience.After high temperature kiln is finished using, no matter whether structure is destroyed, all will carry out destructiveness and remove, and cannot recycle, and causes material unaccounted-for (MUF) and the wasting of resources.Therefore, increasing technical staff shifts to an earlier date pre-formed technique by the employing of kiln used unit and produces, but its single preform structure complexity, size is larger, manually cannot carry, need mechanical hoisting, therefore practices well is reserved suspension hook on prefabricated component, and suspension hook lifting is convenient, durable, but in assembling process, need to adopt oxygen rifle to cut off on pre-buried mounted prefabricated component suspension hook, to guarantee the flatness of each assembling face, after cutting off, this prefabricated component also just cannot lift by crane again, cannot reuse, cause the one waste of resource.
Summary of the invention
The utility model overcomes above-mentioned the deficiencies in the prior art provides a kind of simple in structure, easy for installation and can meet repeatedly that lifting requires and the pre-buried boom hoisting of prefabricated component of assembling repeatedly.
The technical solution of the utility model is achieved in that the pre-buried boom hoisting of a kind of prefabricated component, comprise hanging bolt, this boom hoisting also comprises built-in metal frame and at least two built-in metal pipes that are arranged in parallel, on described built-in metal pipe, offer the metal aperture of passing for built-in metal frame, described built-in metal pipe lower end is all welded with anchor studs, on described built-in metal pipe upper end tube wall, be provided with internal thread, the internal thread of described built-in metal tube wall matches with the screw thread on described hanging bolt; Described built-in metal pipe and described metal frame are arranged in prefabricated component grinding tool, and the upper surface of described built-in metal pipe is concordant with described prefabricated component upper surface.
Described built-in metal Guan Weisi, four built-in metal pipes are equidistantly arranged in parallel.
The technique effect that the technical solution of the utility model produces is as follows: during preform production, built-in metal frame is connected as a whole through the metal aperture on built-in metal pipe with built-in metal pipe, anchor studs is welded on metal tube bottom, then be placed in the prefabricated-member mould that needs to produce, guarantee that built-in metal pipe upper surface is concordant with prefabricated component upper surface, after production, hanging bolt and built-in metal pipe are threaded connection, can realize lifting, during installation, remove hanging bolt, can realize seamless integration.During recycling, hanging bolt and built-in metal pipe can be coordinated to lifting again.Described prefabricated metal pipe is built-in metal Guan Weisi, and four built-in metal pipes are equidistantly arranged in parallel, and during lifting, built-in metal pipe is stressed evenly, and safety coefficient is high.
The beneficial effects of the utility model are simple in structure, easy for installation, firmly safety, and interface is smooth, can meet the requirement that repeatedly lifting requires and repeatedly assembles, and economizes on resources.
Accompanying drawing explanation
Fig. 1 is the pre-buried boom hoisting of the utility model one of structural representation while being positioned at prefabricated-member mould.
Fig. 2 be the pre-buried boom hoisting of the utility model while being positioned at prefabricated-member mould structural representation two.
The specific embodiment
The pre-buried boom hoisting of a kind of prefabricated component, as shown in Figure 1, 2, comprise built-in metal frame 1, two built-in metal pipes 2, prefabricated component grinding tool 6 and hanging bolts 5, described built-in metal Guan Shangjun offers the metal aperture 3 of passing for built-in metal frame, anchor studs 4 is all welded in described built-in metal pipe lower end, on described built-in metal pipe upper end tube wall, be provided with internal thread, the internal thread of described built-in metal tube wall matches with the screw thread on described hanging bolt; Described built-in metal pipe and described metal frame are arranged in prefabricated component grinding tool, and the upper surface of described built-in metal pipe is concordant with described prefabricated component upper surface.
Before preform production, built-in metal frame is connected as a whole through the metal aperture on built-in metal pipe with built-in metal pipe, anchor studs is welded on to built-in metal pipe bottom, then by its entirety placement and prefabricated-member mould, guarantee that built-in metal pipe upper surface is concordant with prefabricated component upper surface, after production, hanging bolt and built-in metal pipe are threaded connection, can realize lifting, during installation, remove hanging bolt, can realize seamless integration.During recycling, hanging bolt and built-in metal pipe are coordinated to lifting again, simple in structure, easy to use, and recycling economizes on resources.
In addition, the number of the built-in metal pipe in above-described embodiment can be determined by the size of prefabricated component and weight, can arrange more than three or three, can realize equally the good effect of above-described embodiment.
