Abstract
The utility model relates to a novel tower machine foundation. A plane cross body is composed of thirteen elements, such as a central body which is prefabricated by concrete, a transition element, an end element, etc. A foundation bolt is cast on the transition element and the end element. The central body is provided with bolt holes which are spatially crossed and are corresponding to bolt holes of the transition element and the end element, and the central body, the transition element and the end element are integrally connected by bolts through nuts. The period of disassembly, assembly and transport of the utility model is one twelfth of the period of disassembly, assembly and transport of the existing concrete casting tower machine foundation. The utility model also has the advantages that lots of foundation expenses are saved, a large amount of concrete waste is reduced and the environmental pollution is avoided.
Description
The utility model relates to a kind of novel foundation for tower crane
At present, integral cast-in-situ concrete basis is generally adopted on fixed crane (standard knot body of the tower) basis, and its manufacturing cycle is long, also causes the installation tower machine cycle long simultaneously, thereby prolongs construction period.On the other hand, whole foundation for tower crane volume is too big, and weight is too heavy, unfavorable carrying, can only once use, remove, cause manually a large amount of wastes of concrete material with finishing, must adopt the explosion means when removing, this work is promptly dangerous, also will produce a large amount of concrete discarded objects, has polluted environment again.
The novel foundation for tower crane of the utility model its objective is: design a kind of splicing prefabricated components formula basis, once drop into and can use repeatedly, demolition, installation, fortune conveniently shorten the installation of tower machine, dismounting cycle, improve tower machine utilization rate, but also save a large sum of funds spending.
The novel foundation for tower crane of the utility model is achieved in that a whole concrete basis is divided into the tridecyne prefabricated units, mechanically with component assembly together, imbeds the stratum, and its supporting capacity surpasses former tower machine Cast-in-place concrete basis.Its concrete structure is described in detail in conjunction with the accompanying drawings by embodiment:
Accompanying drawing 1, novel foundation for tower crane plane assembly drawing
Accompanying drawing 2, novel foundation for tower crane C-C sectional drawing
Accompanying drawing 3, novel foundation for tower crane B partial enlarged drawing
Accompanying drawing 4, novel foundation for tower crane A partial enlarged drawing
Accompanying drawing 5, novel foundation for tower crane trapezoid cross section figure
Accompanying drawing 6, the novel foundation for tower crane figure of falling the T-section
Accompanying drawing 7, novel foundation for tower crane G-G sectional view
Accompanying drawing 8, novel foundation for tower crane F-F sectional view
Accompanying drawing 9, former monolithic Cast-in-place concrete foundation for tower crane figure
The structure of Novel tower crane base as shown in Figure 1, by concrete basis (1) and foundation bolt (5) form, its concrete basis is by centerbody (1), excessive part (2), (17) and extremity piece (4) Be combined into a planar ten font, foundation bolt (5) be cast in excessive part (2), (17), And upper its centerbody (1) of extremity piece (4) is shaped as square and adds the cross assembly such as figure 1, shown in 7,8. Have living space in the centerbody (1) cross bolt hole (11), (12), as Bolt hole (11), (12) in excessive part shown in Figure 2 (2), (17) and the extremity piece (4) Corresponding with the bolt hole of centerbody (1), its bolt (11), (12) are by nut (14) Centerbody (1), excessive part (2), (17) and extremity piece (4) are connected as one.
The inventor manufactures the high-strength novel foundation for tower crane of different cross section with high-strength steel-bar reinforced concrete:
The novel foundation for tower crane of embodiment 1, trapezoid cross section as shown in Figure 5
The inventor is firm and easy accessibility for member, at centerbody (1), excessively be provided with sleeve pipe (9), parallels (8), (16) and lasso (7) in the bolt hole of part (2), (17) and extremity piece (4), sleeve pipe (9) one ends connect with parallels (8), parallels (8) connects with lasso (7), and sleeve pipe (9) other end connects with parallels (16).As shown in Figure 3, bolt (11), (12) are connected as one centerbody (1), excessive part (2), (17) and extremity piece (4) by adjusting nut (6), pad (10) and nut (14), be metal during connection and the connecting of metal, can not damage the concrete member, and be convenient to dismounting.
In order to reinforce novel foundation for tower crane, make concave-convex at centerbody (1), excessive part (2), (17) and extremity piece (4) bonding surface, gap location will be adjusted nut (6) with the U sections and buckle, U sections width equates with the slit, to water high strength early strength micro expansion concrete then be packed layer (3) thus guarantee the member globality.For the ease of dismounting, before the cast concrete component surface is located in the slit and be coated with separation layer (13).
In order to prevent in demolition, installation, transportation, to make member scrap phenomenon because of stone bolt is impaired, reserve the steel pipe hole on stone bolt (5) position of excessive part (2) and extremity piece (4), square groove is stayed in the lower end, hole, and nut is in square groove, bolt connects with mechanical type, is convenient to change.Shown in figure (6).
Facts have proved, the novel foundation for tower crane of the utility model is compared with former monolithic Cast-in-place concrete basis (as shown in Figure 9), its demolition, installation, convenient transportation, supporting capacity is strong, safe and reliable, demolition, installation, fortune cycle only are 1/12nd of former Cast-in-place concrete bases, have improved tower machine utilization rate, shorten the construction period greatly, save the writing spending.Novel foundation for tower crane can use repeatedly, from and saved a large sum of basic expense, also reduced a large amount of concrete discarded objects, avoided environment pollution, therefore, novel foundation for tower crane is the desirable basis of fixed crane (standard knot body of the tower).
