Abstract

The invention belongs to the technical field of building equipment, and provides a detachable tower foundation. The main characteristics are that the tower foundation comprises a base seat and a beam; the base seat is a crossed channel steel base seat formed by a centre base seat and four side base seats connected with the four sides of the centre base seat; a support member is arranged in the base seat; a crossed steel beam in the same shape as the base seat is arranged on and fixedly connected with the base seat; and a tower-crane base seat is correspondingly arranged on the upper surface of the steel beam. Compared with the existing disposable tower foundation and the prior detachable power foundation, the invention has the advantages of easy mounting and detachment, convenient transportation, repeatable use, reduced building cost, and the like.

Description

A kind of detachable tower foundation

Technical field

The invention belongs to the building implements technical field, relate to a kind of column foot, be specifically related to a kind of detachable tower foundation.

Background technology

In present highrise building process of construction, often use tower crane, tower crane will be done the basis with column foot can be firm.The construction of tradition column foot is to make up disposable concrete structure on the ground, and column foot becomes permanent discarded object to treat to finish the building construction afterwards, not only wastes constructional materials, and causes environment pollution.Existing a kind of detachable tower foundation, there is the beam of right-angled intersection on the column foot surface, and each beam is made up of several parts by the steel pipe cross-under, though whole column foot is detachable, but its load-supporting part is a reinforced concrete structure still, and it is few to exist access times, the defective of dismounting inconvenience.

Summary of the invention

The inventor finds that existing column foot exists above-mentioned defective in daily building construction process, through constantly exploring, the object of the invention is to provide a kind of detachable tower foundation, and the column foot repeated multiple times is used, and easy accessibility, saves cost.

For achieving the above object, the technical solution used in the present invention is that this detachable tower foundation structure comprises: pedestal, beam, described pedestal is cross-shaped channel-section steel pedestal, pedestal is made of with four side pedestals that are connected with its four limit and bolton is connected central seat, described central seat and side pedestal are cuboid, in pedestal, be provided with supporting member, on pedestal, establish the cross-shaped girder steel identical with its shape, girder steel divides main girder steel and constitutes by two secondary girder steels that pin is connected with its dual-side, girder steel and pedestal are fastenedly connected, and establish the tower crane pedestal at main girder steel and every secondary girder steel upper surface correspondence.

Supporting member in the described pedestal, be in central seat and four side base cavity, to be equipped with a plurality of channel-section steel bracing frames identical with the pedestal cross section, vertical direction sets firmly a channel-section steel support column in the middle of each bracing frame, the support column both sides are established the angle bar support bar respectively in supporting frame-saw, and the support column two side is welded two bolts that stretch out pedestal top respectively in the support frame as described above frame; Described girder steel and pedestal are fastenedly connected, and refer to that the girder steel cross-sectional width is identical with the width of channel-section steel support column, and girder steel is fastening with the bolt and the pedestal that stretch out pedestal by pressing plate.

The pedestal inside of described pedestal is liquid sealing.

The present invention adopts technique scheme and the designed this detachable tower foundation of measure, because the load-supporting part of column foot is that steel work and column foot are by many parts be combined into, can be repeatedly used, and dismounting, installation, transportation aspect, because base interior is set to liquid sealing, so can fill water to increase the tonnage of column foot in base interior, correspondingly strengthen the stability of column foot, and saved building costs.

Description of drawings

Fig. 1 represents the overall structure schematic diagram of a kind of detachable tower foundation of the present invention;

Fig. 2 represents the structural representation of base interior of the present invention;

Fig. 3 represents the supporting member structural representation of pedestal of the present invention.

The specific embodiment

Specify below in conjunction with the structure of drawings and Examples a kind of detachable tower foundation of the present invention.

Referring to Fig. 1, Fig. 2, Fig. 3, the structure of a kind of detachable tower foundation of the present invention is made up of pedestal 1 and beam 2, wherein, pedestal 1 is cross-shaped channel-section steel pedestal, four side pedestals 1.2,1.3,1.4 that pedestal 1 is connected by central seat 1.1 with its four limit and bolt 3 is fastenedly connected, 1.5 constitute, described central seat 1.1 and side pedestal 1.2,1.3,1.4,1.5 be cuboid, at central seat 1.1 and four side pedestals 1.2,1.3,1.4,1.5 be equipped with a plurality of channel-section steel bracing frames 4 identical in the cavity with the pedestal cross section, vertical direction sets firmly a channel-section steel support column 5 in the middle of each bracing frame 4, and support column 5 both sides are established angle bar support bar 6.1,6.2 respectively in bracing frame 4 frames, in supporting frame-saw 4, weld respectively on support column 5 two sides and stretch out two bolts 7.1,7.2 on pedestal 1 top; On pedestal 1, establish the cross-shaped girder steel 2 identical with its shape, 2 fens main girder steels 2.1 of girder steel and two secondary girder steels 2.2 that link to each other by pin with its dual-side, 2.3 constitute, girder steel 2 cross-sectional width equal the width of channel-section steel support column 5, girder steel 2 is by pressing plate 8 and the bolt 7.1 that stretches out pedestal 1,7.2 it is fastening with pedestal 1, upper surface at main girder steel 2.1 and two secondary girder steels 2.2,2.3 sets up tower crane pedestal 9.1,9.2 separately, 9.3,9.4.In order to improve the tonnage of column foot, increase the stability and the security reliability of column foot, pedestal of the present invention 1 inside can be the liquid sealing state, during use water is filled to increase the tonnage of pedestal 1 in pedestal 1 inside.

The present invention in use, dig out earlier the dell of a cross shape on the ground, the bottom surface in compacting hole, in the hole, fill a certain amount of sand then, the surface of flat sand is rammed in compacting, pedestal of the present invention is lifted on the surface of cross hole sand, with fills with water in the pedestal (can add anti-icing fluid again winter under adverse circumstances) and check its sealing again, then beam is lifted on the pedestal, pressing plate is pressed on the beam and the fastening bolt that stretches out pedestal top makes beam and pedestal be tightened to one.In actual use, can column foot of the present invention be embedded in underground wholly or in part, also or place on the ground according to actual conditions.After treating the present invention all installing inspection, the installation work of construction tower crane on beam again.

Column foot of the present invention adopts steel frame construction to build up fully, can satisfy of the requirement of various engineerings to the column foot tonnage, compare with existing disposable column foot and detachable tower foundation, have and ensuring safety, be easy to installing/dismounting on the basis reliably, be convenient to transportation, can repeatedly use, reduce plurality of advantages such as building costs, this product has solved a building field puzzlement people difficult problem for many years, will exert far reaching influence.
