Detailed Description
According to the modular building, the modular building can be quickly constructed, labor cost is saved, and the modular building has the advantages of being green and environment-friendly.
Modular buildings are usually constructed by first fixing the columns used to support (stress) the building to the piers and then performing other building operations. In the prior art, in order to quickly fix the stand column and the pier, the column base of the stand column and the embedded part in the pier are usually welded and fixed (the embedded parts in the stand column and the pier are made of steel materials), or a plurality of groups of bolts are adopted to connect and fix instead of welding and fixing. Although these fixing methods can quickly achieve connection, the later time when the building needs to be removed, the problem of difficult dismantling is faced. Shear keys between the upright columns and the pier are also cancelled in some fixing modes so as to achieve the purpose of quick disassembly and assembly, but the mode seriously weakens the shear resistance of the column base nodes and increases the collapse risk of the building.
In order to meet the requirement that some modularization buildings (such as temporary vacation houses, public toilets and the like) need to be moved in the later period, and can be quickly disassembled and assembled, and easily meet the structure manufacturing requirement and installation error, the inventor provides a new scheme, namely a column base node for modularization buildings, so that the quick disassembling and assembling of the column base node are realized, and the anti-shearing capacity of the column base node is also greatly improved.
The column base node for the modular building according to the present invention is further described in detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the claims and the following description. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.
The present embodiment describes a column base node for a modular building in detail, as shown in fig. 1 and fig. 2, fig. 1 is a schematic side structure diagram of the column base node provided in the present embodiment; fig. 2 is a top view of the column base node provided in the present embodiment.
The pier in the common column base node is usually made of concrete, and the upright column is made of steel, so the column base node for the modular building is described by taking the upright column made of steel material and the pier made of concrete as an example in the implementation. In the scheme that this embodiment provided, stand 1 is the steel column commonly used among the prior art promptly, can also connect girder steel 2 to form the building frame in the modularization building with girder steel 2 expert of connecting. The upright post 1 and be equipped with connecting portion between the pier 3, upright post 1 passes through connecting portion erects to be connected on pier 3. In order to achieve the detachable connection of the upright 1 to the pier 3, the connection comprises an upper mounting unit 41 and a lower mounting unit 42; the upper mounting unit 41 is fixed at the bottom of the upright post; the lower mounting unit 42 is fixed on the column pier 3 and detachably connected with the upper mounting unit 41; the column 1 in this embodiment is made of steel, and a steel plate may be used as the upper mounting unit 41 for the convenience of mounting and connection. Meanwhile, in order to make it easier to butt-match the lower mounting unit 42 and the upper mounting unit 41, the lower mounting unit 42 is also made of a steel plate.
The upper mounting unit 41 and the lower mounting unit 42, which are both steel plates, may be implemented using bolt connections if a detachable connection is required. In order to enhance the firmness of the connection of the upright 1 to the upright 1 and to simplify the structure and facilitate the fixing of the upper mounting unit 42 to the pier 3, the present embodiment uses an anchor bolt 43 cast into the pier 3 for this purpose.
As shown in fig. 1, one end of the anchor bolt 43 extends out of the pier 3 and penetrates the upper mounting unit 42 and the lower mounting unit 42, and the other end of the anchor bolt 43 is cast in the pier 3 to achieve that the anchor bolt 43 is firmly fixed in the pier 3, and an anchor plate 44 may be further provided at the other end of the anchor bolt 43 to improve the anchoring ability of the anchor bolt 43. Since the anchor bolt 43 penetrates through the upper mounting unit 41 and the lower mounting unit 42, the detachable connection between the upper mounting unit 41 and the lower mounting unit 42 can be realized only by providing a screw thread at a position on the anchor bolt 43 near one end thereof and by matching with the nut 45. In order to enhance the fixing effect of the nut 45 and prevent the nut 45 from slipping, a spacer 49 is further provided between the nut 45 and the upper mounting unit 41. The thickness, area and the like of these spacers 49 can be specifically selected according to the stress characteristics and bearing requirements of the modular building, and will not be described herein.
In this embodiment, only two anchor bolts 43 are used around the column 1 to connect the upper mounting unit 41 and the lower mounting unit 42 together. However, it will be readily understood by those skilled in the art that a greater number may be provided to ensure sufficient connection strength between the column 1 and the pier 3. Of course, the specific number can be set according to actual needs.
When the column 1 is connected upright on the pier 3, the column 1 distributes the forces from the modular building to the pier 3. It is well known that the more uniform the force is, the more external force can be borne and the maximum load bearing capacity can be exerted, and conversely, premature failure is easily caused. In the case of the pier 3 formed of concrete material, uneven application of force can easily lead to accelerated collapse of the pier, which results in loss of load-bearing capacity. In order to allow the force applied to the pier 3 by the column 1 to be more evenly distributed to the pier 3, the present embodiment also fills the non-shrink grout 5 between the column 1 and the pier 3. Because a connecting part is also arranged between the upright post 1 and the pier 3. A position where non-shrink grouting material 5 can be filled is between the lower installation unit 42 and the column block 3.
Also, whether the lower mounting unit 42 is in a horizontal state affects the stress state of the pier 3. The upper mounting unit 42 is also leveled before filling the non-shrink grout 5. In order to be able to level the upper mounting unit 42, a leveling unit 46 is also provided between the upper mounting unit 42 and the column block 3. In this embodiment, the leveling unit 46 may be a nut that is fitted over the anchor bolt 43, so that the horizontal state of the upper mounting unit 42 can be adjusted by screwing the nut. As can be seen from fig. 1, the two anchor bolts each have a nut for leveling purposes.
It is further suggested in the foregoing that the prior art column base node has poor shear resistance, which poses a potential risk to the stability of the modular building. In order to improve the shear resistance of the column base node, the present embodiment provides an implementable solution. That is, the connecting portion further includes an upper bushing 47 penetrating the upper mounting unit 41, and a lower bushing 48 penetrating the upper mounting unit 41 and the lower mounting unit 42; the upper bushing 47 is fixed to the upper mounting unit 41; the lower bushing 48 is fixedly connected to the lower mounting unit 42, and one end thereof penetrates into the upper bushing 47. Such an effect can be obtained by such a scheme: when a large shearing action is applied to the toe node, in addition to the frictional force between the upper mounting unit 41 and the lower mounting unit 42 acting against a certain degree of shearing action, the external shearing action can be resisted by the interaction between the upper sleeve 47 and the lower sleeve 48.
It will be readily appreciated that, since the upper casing 47 and the lower casing 48 need to be able to resist the shearing action of the outside, the diameters of the upper casing 47 and the lower casing 48 need to be matched and can be selected according to the actual construction operation. The sleeve has simple structure, the sleeves with different diameters are easy to screw and fix without bolts, and the shearing resistance of the column base node can be greatly improved only by the limiting action between the two sleeves.
In this embodiment, the axes of the upper sleeve 47 and the lower sleeve 48 coincide with the axis of the upright post 1, which is convenient for installation and reasonable in layout, and reduces the extra space occupation.
According to the scheme provided by the above embodiment, when the column base node is actually constructed, the column pier 3 can be formed by pouring concrete, and the anchor bolt 43 is poured in the column pier 3. After the pillar 3 is formed by casting, the position data of the anchor bolt 43 is measured, and the upper mounting unit 41 and the lower mounting unit 42 are manufactured according to the measured data. Next, a lower casing 48 (both of which may be made of steel pipe) is welded on the lower mounting unit 42, and then the lower mounting unit 42 is mounted on the pier 3, and leveling and filling of the non-shrink grouting material 5 are performed. The specific position of the upper bushing 47 in the upper mounting unit 41 is determined by measuring the position data of the lower bushing 48, and the upper bushing 47 is welded to the upper mounting unit 41. And finally, splicing the upper mounting unit 41 and the lower mounting unit 42 together, and screwing the nuts to fix the upper mounting unit and the lower mounting unit to finish the mounting work.
In the column base node for the modular building provided by the embodiment, the upper mounting unit 41 and the lower mounting unit 42 are arranged between the upright post 1 and the column pier 3, the upper mounting unit 41 is fixed at the bottom of the upright post 1, the lower mounting unit 42 is fixed on the column pier 3 and is detachably connected with the upper mounting unit 41, so that the upright post 1 and the column pier 3 can be quickly disassembled and assembled, an upper sleeve 47 and a lower sleeve 48 are further provided between the upright post 1 and the column pier 3, the upper sleeve 47 penetrates through the upper mounting unit 41, the lower sleeve 48 penetrates through the upper mounting unit 41 and the lower mounting unit 42, and the shearing resistance of the column base node is improved by the connection mode that the upper sleeve 47 is sleeved on the lower sleeve 48.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
