Abstract

The utility model discloses a mini type of concrete prefabricated and assembled multipurpose tower crane foundation, which comprises a concrete perform combined system, a connection device of a combined system and multi-assembling bolt holes used for a stacker crane. The combined system comprises a centerpiece and a tail piece. The centerpiece is a rectangular in a cross body. One end of the tail piece is rectangular, and the other end of the tail piece is an inverted 'T' character shape. The rectangular end part of the tail piece which is perpendicular to the centerpiece opens holes. The combined head faces of the centerpiece and the tail piece are kept together. The connecting boards with the same hole site cover the two sides of the combined head faces opened with holes. A joining goes through the holes (including the holes of the connecting boards), and then is fixed by fasteners. The utility model can completely satisfy the different types of stacker cranes which are less than 400KN. M tons. The utility model has the advantages of small size, light weight, simplicity, practice and convenient operation, which can save the costs of transportation and site operation. The usage of the mini type concrete prefabricated and assembled multipurpose tower crane foundation certainly brings a better benefit to stacker crane foundation production units and users.

Description

Small-sized concrete precast assembly is used foundation for tower crane more

Technical field:

The utility model relates to construction implement and installs and fixes the concrete basis, relates in particular to the concrete precast assembly and uses foundation for tower crane more.

Background technology;

At present, in building operations, the concrete precast assembly is used foundation for tower crane more, to have a site operation cycle short because of it, and demolition, installation, fortune are convenient and swift, non-environmental-pollution, the No Assets waste, and can improve the utilization ratio of tower machine and the use cost of saving the tower machine, and generally be subjected to attention in the industry, applied in many areas.Submit to before the inventor (application number is: 2004200804052) about " the concrete precast assembly is used foundation for tower crane more ", prior art further improvement and innovation have been done, as improvement to the coupling arrangement of foundation for tower crane assembly, design to the fixing position, many assembling bolts hole of tower machine, and dispose antitorque counterweight etc., it is perfect that concrete precast assembly foundation for tower crane has further been obtained, and prefabricated simple to operate with assembly unit, range of application is wider.But this basis is used for the suspicion that little tonnage tower machine then has low load with strong power, bearing capacity is more than needed too many, uneconomical, and adopt polylith prefabricated component axial through bore to connect, also be provided with shearing resistance part etc. between the prefabricated component, higher relatively to the making requirement of prefabricated component, it connects also complicated, because the concrete prefabricated member number of packages on basis is many, freight volume and site operation cost have been increased simultaneously.

Summary of the invention:

The technical problems to be solved in the utility model is: providing a kind of can expire small-sized tower machine and hang, transport requirement, can simplify the making of foundation for tower crane again, makes things convenient for on-site consolidation to connect, and saves the small-sized foundation for tower crane of transportation and construction cost.

The technical solution of the utility model is achieved in that a kind of small-sized concrete precast assembly uses foundation for tower crane more, comprises the assembly of concrete prefabricated member, and the linkage of assembly, tower machine be many assembling bolts hole of usefulness fixedly; Described assembly is made of central part, extremity piece, central part is that rectangle cross body, extremity piece one end are rectangle, the other end is for falling " T " font, have the hole perpendicular to central part, extremity piece rectangle end, central part, extremity piece fit tightly together in conjunction with end face, are provided with the junction plate with the position, hole, toppedly have on the two sides in hole in it, attachment passes (hole that comprises junction plate) from the hole, fix with fastener then.

Described attachment is a screw rod, and fastener is a nut, further improves as this practicality, and described attachment is the flexible material steel strand, and then fastener is anchor slab and clamping plate.

Described junction plate with the position, hole, the position in this hole and central part and extremity piece corresponding in conjunction with the end face back that is closely linked, what of hole also are decided by institute's number of aperture on central part, the extremity piece; Described institute number of aperture, this hole has at least more than one, and up and down on the Kong Zaiyi bar vertical line, the back gauge of hole and central part, extremity piece end is the 2-4 centimetre; This junction plate thickness is the 2-4 centimetre.

Beneficial effect:

The utility model can satisfy the following dissimilar tower machines of 400KN.M tonnage fully to be used, and volume is little, in light weight, can save cost of transportation and site operation cost; Because coupling arrangement is to have the hole in the end of central part and extremity piece, connect with bolt nut, simple, practical, operate also easyly, and the making of concrete prefabricated member requirement is also relatively low, technology is simple.This small-sized concrete precast assembly is used the use of foundation for tower crane more, brings better economic benefits can for undoubtedly foundation for tower crane production unit and user.

Description of drawings:

Fig. 1 is the utility model schematic top plan view.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is Fig. 1 partial enlarged drawing.

Fig. 4 is the front view of the local amplification of Fig. 1 that is Fig. 3.

The specific embodiment:

Now in conjunction with the accompanying drawings, the utility model is described in further detail.

As shown in Figure 1, the utility model is assembled by the polylith concrete prefabricated member, and the concrete prefabricated member that is used for assembly unit needs tower machine fastening devices when making, and the linkage between the prefabricated component is done pre-buried earlier.

As shown in Figure 2, two of the prefabricated bolts hole that communicates in each both sides, end of central part 1, the center in hole is on a vertical line up and down, last hole and end top margin, following hole and end bottom margin respectively are 3 centimeters, the distance of they and termination also is 3 centimeters, equally, also prefabricated 2 bolts hole that communicate in the both sides of extremity piece 2 rectangular ends, the center in its hole is also as above-mentioned (as shown in Figure 2), also should (application number is: the technical scheme 2004200804052), the fastening devices of prefabricated basis and tower machine be many assembling bolts hole (not giving unnecessary details at this) by another application case of the inventor on extremity piece.

Prefabricated central part 1 is a rectangle cross body, the end of extremity piece 2 rectangular ends and central part 1 is combined (as shown in Figure 2) closely, get one 2 centimeters thick steel plates, its height is a little less than extremity piece 2 rectangular end height, its long twice of getting two binding end transverse holes distances, and on steel plate, get the hole that is complementary with binding end two side holes 3, junction plate 5 is fitted to the binding end both side surface of central part 1, extremity piece 2, pass hole 3 with long bolt from a side again, and tighten fixing (as shown in Figure 4) with nut at opposite side, promptly finished on-site consolidation of the present utility model.Can select respective bolt holes to be connected and fixed according to tower machine type, the tower machine can come into operation.
