Description
Technical Field
The utility model belongs to the technical field of the construction, concretely relates to submerged steel pipe column base basis.
Background
The rigid connection node of the steel pipe column base has three forms in the design specification of a steel structure, namely an embedded column base, an externally-wrapped column base and an exposed column base. The embedded column bases, the externally wrapped column bases and the exposed column bases are sorted according to the advantages and disadvantages of the anti-seismic performance. The order is reversed in terms of mounting convenience. According to the design and principle of 'anti-seismic standard' strong joint connection, the length of the embedded and externally-wrapped column base steel pipe column wrapped in the concrete structure is generally not less than 2.5d, d is the diameter (or width) of the steel pipe column, and taking a 600mm diameter steel pipe column as an example, the wrapping length is not less than 1.5m, so that the installation is inconvenient, the manufacturing cost is high, and in addition, the externally-wrapped column base with the externally-wrapped column base exposed reinforced concrete expanded is exposed out of the ground more and is not beautiful.
For example, the exposed column base is advantageous in terms of simple structure, convenient construction and simple appearance. However, the anti-seismic performance is not very good, the diameter of the connecting anchor bolt is too large, and the problems that the shear key is inconvenient to set and the like easily occur.
Disclosure of Invention
The purpose of the invention is as follows: the utility model aims to provide a sunken steel pipe column base basis to prior art's not enough.
The technical scheme is as follows: the utility model relates to a submerged steel pipe column base foundation, which comprises an embedded part, a steel casing, a steel pipe column and a split bolt which are pre-embedded in a concrete foundation; the welding has the steel to protect a section of thick bamboo on the built-in fitting, the steel protects a section of thick bamboo and is hollow cylinder type structure, the internal diameter that the steel protected a section of thick bamboo is the same with the external diameter of steel-pipe column, the bottom of steel-pipe column inserts in the steel protects a section of thick bamboo, the center that steel-pipe column and steel protected a section of thick bamboo is located same vertical on-line, the bottom that steel-pipe column and steel protected a section of thick bamboo all is provided with the preformed hole of passing the diameter, the preformed hole on steel-pipe column and the steel protected a section of thick bamboo is passed to.
Preferably, the upper portion of built-in fitting is the round steel plate, the diameter of round steel plate is greater than the external diameter that the steel protected a section of thick bamboo, the below welding of round steel plate has the mounting of cylinder type, the bottom of mounting is to the certain radian of centre of a circle bending.
Has the advantages that: (1) the utility model discloses can be widely used in the basis that steel-pipe column and concrete are connected, at first the built-in fitting adopts the mode of buryying, and its intensity and rigidity are bigger compared with the built-in fitting on concrete foundation surface, and the steel protects a section of thick bamboo can effectual reinforcing its steel-pipe column base bending resistance and shear resistance, avoids the steel-pipe column to produce the destruction because of the atress is not enough, through the connection to the stay bolt, makes the atress performance of steel-pipe column better, and its stability and shear resistance obtain effectual enhancement;
(2) the height, the thickness, the diameter and the number of the split bolts of the steel casing can be selected according to the stress of the column base of the steel pipe column, so that the universality is ensured; the utility model discloses simple manufacture, reasonable in design, simple to operate can popularize and apply.

FIG. 1 is a schematic structural view of a steel pipe column base foundation according to the present invention;
fig. 2 is a top view of the steel pipe column base of the present invention.
In the figure, 1-steel pipe column, 2-steel casing, 3-split bolt, 4-concrete foundation and 5-embedded part.
Detailed Description
The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.
Example (b): a submerged steel pipe column base foundation comprises an embedded part 5, a steel casing 2, a steel pipe column 1 and a split bolt 3, wherein the embedded part 5, the steel casing 2, the steel pipe column 1 and the split bolt are embedded in a concrete foundation 4 in advance; the upper portion of built-in fitting 5 is the round steel plate, the diameter of round steel plate is greater than the external diameter that a steel protected 2, the mounting of cylinder type is welded to the below of round steel plate, the bottom of mounting is to the certain radian of centre of a circle bending, the welding has a steel protected 2 on the built-in fitting 5, a steel protected 2 is hollow cylinder type structure, the internal diameter that a steel protected 2 is the same with the external diameter of steel-pipe column 1, insert in the steel protected 2 bottom of steel-pipe column 1, the center that a steel-pipe column 1 and a steel protected 2 is located same vertical on-line, the bottom that a steel-pipe column 1 and a steel protected 2 all is provided with the preformed hole that passes the diameter, to the stay bolt 3 pass the preformed hole on steel-pipe column 1 and a steel protected 2, screw up the bolt.
The utility model discloses mainly used steel-pipe column and concrete foundation connected node department at first buries the built-in fitting with the concrete foundation in, the welding steel protects a section of thick bamboo, need guarantee that steel-pipe column and steel protect a section of thick bamboo be same vertical on-line, then will stretch into the steel and protect a section of thick bamboo and the preformed hole of steel-pipe column to the stay bolt, screw up the bolt, pour the concrete at last.
The utility model discloses can be widely used in the basis that steel-pipe column and concrete are connected, at first the built-in fitting adopts the mode of buryying, and its intensity and rigidity are bigger compared with the built-in fitting on concrete foundation surface, and the steel protects a section of thick bamboo can effectual reinforcing its steel-pipe column base bending resistance and shear resistance, avoids the steel-pipe column to produce the destruction because of the atress is not enough, through the connection to the stay bolt, makes the atress performance of steel-pipe column better, and its stability and shear resistance obtain effectual enhancement; in addition, the height, the thickness, the diameter and the number of the split bolts of the steel casing can be selected according to the stress of the column base of the steel pipe column, so that the universality is ensured; the utility model discloses simple manufacture, reasonable in design, simple to operate can popularize and apply.
As mentioned above, although the present invention has been shown and described with reference to certain preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
