Abstract
The utility model discloses an anti pull rod that floats of hollow superstructure sectional type of cast in situ concrete, its characterized in that anti float the welding of pull rod lower extreme and have the stationary blade, the upper end be 180 degrees fixed hooks, mid portion install turnbuckle, surface position in the template welded the nut of forming a complete set with the turnbuckle lead screw while. The utility model discloses an adopt the anti pull rod that floats, replace the iron wire among the prior art, can guarantee the concrete floor bottom and level, do not keep the remaining later stage fitment that influences.
Description
Technical field
The utility model relates to a kind of cast-in-place concrete hollow building roof sectional type anti-floating pull bar, belongs to technical field of building construction.
Background technology
Cast-in-place concrete hollow building roof operating technique is the domestic new technology grown up in recent years, there is the advantages such as deadweight is light, span is big, rigidity good, sound-insulating and heat-insulating is good, cost is lower compared with solid concrete superstructure, it is particularly useful for the construction work having large bay, large span to require. Owing to onsite concrete deadweight is light and quantity is many, producing buoyant effect when concrete placement, solution is never good, and the lighter causes local floor absolute altitude superelevation, reduces finishing way thickness, and severe one can cause big area to float quality accident occur.
The anti-floating of existing filled internal mold is fixed by the iron wire of diameter 3-5mm. During fixing anti-floating reference mark, first iron wire one end is down passed in template from hole, up wear from hole by iron wire termination after tying with the support system of template, when placing on filled internal mold, the good plate of colligation after iron and distribution bar, the two of iron wire terminations are tightened at anti-floating reference mark place, prevents filled internal mold from floating. After this kind of method template is removed there is a large amount of iron wires in concrete floor bottom surface, affects the decorations of floor later stage. Therefore, the cast-in-place concrete hollow building roof sectional type web member how developing a kind of conveniently assemble and disassemble is those skilled in the art's technical problems urgently to be resolved hurrily.
Practical novel content
In conjunction with the present Research of current cast-in-place concrete hollow building roof construction, cast-in-place concrete hollow building roof sectional type web member is optimized by incorporation engineering actual features, technical problem to be solved in the utility model is: the anti-floating of existing filled internal mold is fixed by the iron wire of diameter 3-5mm, after this kind of method template is removed there is a large amount of iron wires in concrete floor bottom surface, affects the decorations of floor later stage.
In order to realize above-mentioned purpose, the utility model adopts following technical proposals:
The utility model relates to cast-in-place concrete hollow building roof sectional type anti-floating pull bar, it is characterized in that the described lower end of anti-floating pull bar is welded with fixed plate, upper end is 180 degree of fixing hooks, fixing hook is welded with nut, nut is connected with middle portion, middle portion installs flower basket bolt, is welded with the nut supporting with flower basket bolt screw mandrel at template upper surface location simultaneously.
In a preferred implementation of the present utility model, it is characterised in that described fixed plate is provided with the hole for fastener is fixed.
In a preferred implementation of the present utility model, described anti-floating pull bar is prefabricated processing outside field.
In a preferred implementation of the present utility model, described fixed plate is connected with middle portion by welding process.
Adopt pouring concrete hollow building cover sectional type anti-floating pull bar of the present utility model, at least having the following advantages one or more or all:
1. have developed the anti-floating pull bar being applicable to cast-in-situ hollow building roof anti-floating filled internal mold anti-floating, by connecting upper reinforced mesh and bracing frame, prevent filled internal mold from occurring floating in casting concrete process.
2. with tradition iron wire stationary phase ratio, top crotch dimensional standard is unified, decreases the upper net plate positionerror that when adopting iron wire fastening, artificial origin causes, effectively ensure that construction quality.
3. anti-floating pull bar adopts sectional type to connect, and the outer bar removed can recycle, and saves a large amount of artificial and goods and materials, it is not necessary to cutting avoids pollution.
4. i.e. dismountable anti-floating pull bar after intensity on floorslab concrete, backs out screw mandrel during dismounting, removes for roof plate template and provide conveniently, decrease the breakage of template, it is to increase template has enough to meet the need utilization ratio.
Accompanying drawing explanation
Fig. 1 cast-in-place concrete hollow building roof sectional type anti-floating pulling rod structure schematic diagram, wherein 1 is the fixing hook in upper end; 2 is nut; 3 is flower basket bolt; 4 is lower end fixed plate; 5 is welding site.
Embodiment
Below in conjunction with the drawings and specific embodiments, technology contents of the present utility model is described in detail.
Embodiment 1:
Cast-in-place concrete hollow building roof sectional type anti-floating Tiebar structure is as shown in Figure 1, the described lower end of anti-floating pull bar is welded with fixed plate, upper end is 180 degree of fixing hooks, fixing hook is welded with nut, nut is connected with middle portion, middle portion installs flower basket bolt, is welded with the nut supporting with flower basket bolt screw mandrel at template upper surface location simultaneously; Described fixed plate is provided with the hole for fastener is fixed; Described fixed plate is connected with middle portion by welding process.
Cast-in-place concrete hollow building roof sectional type anti-floating pull bar using method:
During fixing anti-floating reference mark, hole in position, anti-floating reference mark with electric hand drill, by flower basket bolt through template, fixing hook is arranged on flower basket bolt, fixing hook hooks hollow building cover upper net plate reinforcing bar, lower end fixed plate fastener is fixed on the upper level bar of supporting frame, and fastening flower basket bolt prevents filled internal mold from floating in casting concrete process.
The above is preferred embodiment of the present utility model; it is noted that for those skilled in the art, under the prerequisite not departing from principle described in the utility model; can also making some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model. For the technician in general field, any apparent change it done under the prerequisite not deviating from the utility model connotation, all by forming the infringement to the utility model patent right, will undertake corresponding legal obligation.
