Abstract
The utility model relates to a nonstandard foundation used for fixing a tower crane, which comprises a concrete bottom pattern plate, and is characterized in that a plurality of drill holes are dug on the concrete bottom pattern plate and are internally provided with four groups of chemical glue bonding planting reinforcing bars, the two groups of the planting reinforcing bars are anchored and connected with a transformation steel girder, the two transformation steel girders are parallel to each other and are erected with two connecting transformation supports parallelly arranged, two tower crane bases are fixedly connected on each connecting transformation support, and the four tower crane bases form a rectangular position. The nonstandard foundation has the advantages of being not influenced by working conditions of the bottom pattern plate during installation of the tower crane, being capable of flexiably arranging the form of the tower crane foundation, having a simpler construction technique and being convenient in operation.
Description
Technical field
The utility model relates to a kind of fixing nonstandard basis of tower crane that is used for.
Background technology
At present when high-building construction, adopt large-scale tower crane to allocate and transport various constructional materialss, because the boom of tower crane can become orthogonal profile with body of the tower, so can be installed in crane near the building of constructing, its effective work range is superior to crawler belt, rubber tired crane, particularly occur high-rise, behind the super highrise building, the working depth of tower crane can reach 100～160m, more embody its superiority, it is easy to operate to add itself, characteristics such as luffing is simple, comprehensive certain situation is both at home and abroad seen the lifting of builing industry from now on, transportation, the key machine of lifting operation remains tower crane.And in recent years, build more and more higher, a large amount of super high rise buildings has appearred, what conventional tower crane adopted is to utilize the basis of the part of self having built up of building as large-scale tower crane, the operating mode of arranging along with tower crane becomes increasingly complex, the form of tower crane also changes day by day, tower crane generally adopts traditional embedded part to construct at present, promptly still placing built-in fitting in the uncompleted former concrete structure, and with modes such as tower crane base and built-in fitting firm welding, this kind mode must be before big bottom slab concreting concrete be accurately buried embedded part underground and is finished, and relatively is subjected to the restriction of engineering time.Because the load that tower crane need bear is big more, its area is big more, and difficulty of construction is also high more.If the big base plate of concrete has been constructed and has been finished, according to traditional practice of building the tower crane concrete foundation again, more loaded down with trivial details and the man-machine material expense increasing of required operation, and treat that this concrete foundation of tower crane dismounting back need cut, and building waste transported outward, the more important thing is destructible original base structure in the construction, cause unsafe factor.Therefore demand developing the nonstandard basis that tower crane is fixed that is used for that makes new advances urgently.
Summary of the invention
The purpose of this utility model is to solve in the prior art existing problem in the tower crane immobilizing foundation is set, and a kind of fixing nonstandard foundation structure of tower crane that is used for is provided.A kind of fixing nonstandard basis of tower crane that is used for of the utility model design, comprise the big base plate of concrete, it is characterized in that: digging at the big base plate of concrete has several boring, boring in by chemical glue cementing value muscle, the value muscle that is worth is formed four groups, two class value muscle and a conversion girder steel anchor connection, two conversion girder steels are parallel to each other, put on the shelf at two conversion girder steels and to be provided with two connections conversions bearings that be arranged in parallel, be fixedly connected with two tower crane bases on the every connection conversion bearing, four tower crane bases constitute a rectangle position.The utility model has the advantages that the influence of big base plate operating mode when not installed by tower crane, the form of tower crane can be set neatly, construction technology is simpler, and is easy to operate.
Description of drawings
Accompanying drawing 1 is a structure schematic top plan view of the present utility model.
Accompanying drawing 3 is looked schematic diagram for structure of the present utility model front.
The specific embodiment
Comprise the big base plate 1 of concrete among the figure, it is characterized in that: digging at the big base plate of concrete has several boring 2, boring in by chemical glue cementing value muscle 3, the value muscle that is worth is formed four groups, two class value muscle and a conversion girder steel 4 anchor connections, two conversion girder steels are parallel to each other, and putting on the shelf at two conversion girder steels is provided with two connection conversion bearings 5 that be arranged in parallel, be fixedly connected with 6, four tower crane bases of two tower crane bases on the every connection conversion bearing and constitute a rectangle position.
Value muscle construction sequence: boring: should use electric hammer boring, should note avoiding damaging the interior original reinforcing bar of concrete during boring.Clear hole: before implanting reinforcing bar with the clear hole of special-purpose steel brush at least 3 times.Dedusting: adopt air blowing tube or the interior dust of air compressor removing hole wall and ponding at least 3 times.The pre-notes: use special-purpose combining nozzle, the 4 rifle adhesives that flowed out by combining nozzle must die out at first.Injecting glue: begin injecting glue after at the bottom of the combining nozzle patchhole, slowly combining nozzle is moved outward, guarantee no bubble or hole in the hole, injecting glue is to filling up 2/3 of hole depth.Bar planting: implant reinforcing bar to there being colloid to overflow with continuous rotation mode, gel time
Preceding implantable or adjustment reinforcing bar,
Extremely
Between can not the disturbance reinforcing bar.Follow-up construction:
Extremely
Between can begin construction, but can not apply moment of torsion (25% design power value).
After, can bring into play design power value fully.
During adopted value muscle mode, can bear the tower crane load of suitable numerical value, use more flexibly effectively than other forms of tower crane.
In follow-up construction, two conversion girder steels are carried out anchor connection with the value muscle, fixedly connected with the conversion girder steel again after subsequently again will two connecting the parallel placement of conversion bearing, and at last four tower crane bases changed bearing and can be carried out the installation of tower crane after fixedly connected with being connected.After the building operations completion, also need not go again and cut construction in its basis, thereby also can not exert an adverse impact to concrete foundation.
