Detailed Description

In the following description of the preferred embodiments of the present invention, for the purpose of illustration and description, reference will be made to the accompanying drawings, in which the upper, lower, left and right orientations in the drawings will be used in the following detailed description for indicating the positions of the various elements in the drawings, and the description of the orientations is not intended to be limiting.

As shown in fig. 1A, and with simultaneous reference to fig. 2A (which is a perspective view of fig. 1A), there is shown a column 100 comprising four corner steel tubes 21, each corner steel tube 21 preferably being a rectangular steel tube, and most preferably being a square steel tube. Each corner steel tube 21 is located at a corner position 20 of the column 100. By corner position is meant a region in which the outer edge of the cross-section of the post 100 forms a turn, such as shown in fig. 1A, which is a 90 ° turn corner position 20. Between the adjacent corner steel pipes 21, side plates are provided, and a corrugated side plate 3 may be preferable. Various connecting methods, such as welding, can be adopted for the corner steel pipes 21 and the corrugated side plates. The wave height and wave distance of the corrugated side plate 3 can be set according to a mechanical formula. In fig. 1A, a columnar area 9 is defined by four corner steel pipes 21 in cooperation with four corrugated side plates 3. In other embodiments, as shown in fig. 1B, a cylindrical region 9 can be enclosed by four corrugated side plates 3 without the need for four corner steel pipes 21. In the two enclosing manners shown in fig. 1A and fig. 1B, the enclosed columnar region 9 is considered as a rectangular parallelepiped columnar region, and both are within the intended scope of the present invention. In either fig. 1A or 1B, concrete 5 may be poured into the columnar areas 9, while no concrete is poured into the four corner steel pipes 21. It should be noted that in this example, concrete is used as the most common type of filling material, and in fact, the filling material also includes many other common types, such as high-strength concrete, high-strength mortar, self-compacting mortar, high-strength grouting material, etc., and these filling materials can be applied in the column 100 of the present invention, and can replace the concrete 5 in this example, and are also within the scope of the present invention. This arrangement provides for the solid middle section of the column 100 to be reinforced with rammed concrete 5, while the four corner sections 20 are more flexible, while taking advantage of the two aspects of concrete and steel construction, and can be variously treated and later expanded in detail.

In fig. 2B, a first drawknot panel 4 is also employed in this preferred embodiment. Referring to fig. 3A, it can be understood that both ends of the first drawknot plate 4 are respectively provided on the diagonal corner steel pipes 21, thereby performing a reinforcing function. In fact, as shown in fig. 2B and 3A, two first drawknot plates 4 are used, crosswise to each other, i.e. cross drawknot plates, in order to achieve a better result. In other embodiments (not shown in the figures), the two first drawknot panels 4 criss-crossing each other may be located at different heights of the column 100, forming a top-view criss-crossing of spatially different heights, i.e. a criss-crossing in top view 3A, but in practice the two first drawknot panels are not at the same height of the column 100. In certain more preferred implementations, in conjunction with fig. 3B and 4, in addition to the corner steel pipes 21 at the corner positions, side steel pipes 22 are provided between adjacent corner steel pipes 21. It should be noted that, although the side steel pipes 22 are not different in material from the corner steel pipes 21 at the corner positions 20 in the first drawwork 4, the side steel pipes 22 are not provided at the corner positions 20 but at the positions of the corrugated side plates 3. In the preferred embodiment, as shown in fig. 3B and 4, a second drawknot plate 42 is connected between each pair of oppositely positioned side steel tubes 22. In practice, the two second drawknot plates 42 are thus common with the two first drawknot plates 4And a'm' -shaped drawknot plate is formed. Similar to the first drawknot plates 4 forming the spatial cross, the two second drawknot plates 42 are not necessarily arranged at the same height of the column 100, and only the cross in a shape like a Chinese character 'mi' in fig. 3B is required to be formed, so that it can be understood that even the two first drawknot plates 4 and the two drawknot plates 42 are not at the same height of the column 100, and the cross in a shape like a Chinese character 'mi' can be realized in overlooking. In some embodiments (not shown), only one pair of oppositely positioned side steel tubes 22 is provided on the basis of a cross drawknot plate to form

A drawknot plate of the shape is also fully feasible. The technical solutions are intended to be covered by the present invention and are within the scope of the present invention.

Referring to figures 3A, 2B and 5A, an important feature of the preferred embodiment of the invention is shown that it is very convenient to incorporate the diaphragm 1 for the connection of the column 100 to the external beam 6. In the preferred embodiment, the four corner steel pipes 21 are all rectangular steel pipes, the columnar region 9 is a rectangular columnar region, the diaphragm 1 may be in a shape of "hui", and the upper diaphragm 11 and the lower diaphragm 12 have the same shape and may be referred to as diaphragm 1, except that they are placed at different positions. The outer beams 6 are, by way of example only, H-beams, it being reminded that other types of beams, such as hollow beams with rectangular cross-section, etc., are also possible. It should be noted that the "square-shaped" shape should be understood in the broadest sense, that is, any case where the cross section of the pillar 100 has a hollow enclosed area (the cross section projection of the columnar area 9) is the "square-shaped" shape referred to in this patent, and the frame of the hollow enclosed area is not limited to be rectangular, for example, the hollow enclosed area (the inner frame of the "square-shaped" shape) may be rectangular, circular, oval, diamond, racetrack, and other shapes. The outer frame of the "go back" shape may be in various shapes such as rectangle, circle, ellipse, diamond, racetrack, etc., without limitation. For another example, the shapes in FIGS. 6A and 6B of the present invention also belong to the shape of Chinese character' hui

The preferred example of fig. 5A, may be used to connect the external beam 6 and the column 100. At the interface of the column 100 and the external beam 6, the upper surface of the external beam 6 is flush with the upper diaphragm 11, the lower surface of the external beam 6 is flush with the lower diaphragm 12, and the column 100 and the external beam 6 are connected by welding and/or bolting. For welding, the respective edges of the outer beam 6 may be welded separately. As a possible way of bolting, lugs (not shown) may be provided on the outer surface of the column 100 to be bolted to the outer beam 6, and in a more preferred embodiment, additional reinforcement may be provided by welding. The diaphragm 1 can transmit force well by welding or bolting. For example, in the upper cross partition 11 in fig. 5A, the upper flange of the H-beam on the left side is welded to the left outer edge of the upper cross partition 11, and similarly, the upper flange of the H-beam on the right side is welded to the right outer edge of the upper cross partition 11, so that the force of the upper flange of the H-beam on the left side on the upper cross partition 11 and the force of the upper flange of the H-beam on the right side on the OY direction in the XOY plane can be balanced or transmitted to each other. This is an important technical feature of the arrangement of the upper transverse partition 11. The same principle is applied to the lower diaphragm 12 welded at the lower flange of the H-beam, so that the balance of force or the transmission of force is realized, which is not described in detail.

In the above example, the bulkhead 1 completely covers the four corner steel pipes 21 at the corner positions and does not substantially cover the columnar areas 9, with greater efficiency of use and strength. In fact, the diaphragm 1 is skillfully matched with the corner steel tubes 21 (and the side steel tubes 22 if the side steel tubes 22 are provided) without pouring concrete. For the column 100, it may be very high in the height direction of the column 100, and at different heights, parallel outer beams 6 of different heights may be provided. At this time, it is necessary to provide the upper partition 11 and the lower partition 12 at a plurality of heights on one column 100 to match the external beams 6 at different heights to connect at the boundary between the column 100 and the external beam 6. Since concrete is not poured into the corner steel pipes 21, the diaphragm 1 prepared in advance can be installed to its final position together with the outer beam 6, and then the columnar regions 9 can be collectively poured. For example, the high-cast method is adopted, namely, the cast concrete is cast from the highest part to the bottommost part. After the casting operation is completed, the junction between the post 100 and the outer beam 6 may be subjected to additional welding for additional reinforcement. Therefore, in the vertical direction of the column 100, the diaphragm plate 1 is equivalent to a section of corner steel pipe 21 which is connected in series up and down, and does not need to be kept through for pouring concrete, so that the defect that the diaphragm plate 1 cannot be arranged is overcome, and the force applied to the part of the external beam 6 connected with the column 100 can be transmitted into the column 100 through the diaphragm plate 1, so that the force is shared, and the bearing capacity and the safety performance of the column are improved. On the other hand, in the conventional column, since it is necessary to perform construction by a through-type method such as a high-cast method also in the corner steel pipe 21, the bulkhead 1 cannot be installed, and the load-bearing capacity of the column 100 with respect to the outer beam 6 cannot be improved by the bulkhead 1.

It is also noted that the arrangement of the outer beams 6 (i-beams) is shown only in the Y-direction, as shown in fig. 5A. In practice, not shown in the figures, but also in the X direction, the arrangement of the external beams can be carried out simultaneously. Therefore, the utility of the four sides of the square shape of the transverse clapboard 1 can be exerted to the maximum, the best bearing capacity is achieved, and the bearing capacity and the safety performance of the column are further improved.

In addition to the above embodiments showing the upper horizontal partition 11 and the lower horizontal partition 12 both in the shape of "hui", i.e. both in the form of horizontal partitions in fig. 6B, other forms are also possible. For example, as shown in fig. 2C, 2D, 5B, 6A and 6B, the upper horizontal partition 11 takes the form of fig. 6A, and the lower horizontal partition 12 takes the form of fig. 6B. Specifically, at this time, the upper horizontal partition plate 11 does not cover the corner steel pipe 21 at the corner position of the column 100, the upper horizontal partition plate 11 is in the shape of a "short square box", and the lower horizontal partition plate 12 covers the corner steel pipe 21 at the corner position of the column 100, and the lower horizontal partition plate 12 is in the shape of a "box". The upper transverse partition plate 11 has the characteristic of not breaking the corner steel tube 21, in the preferred embodiment, the stroke width of the 'short rectangular-square-shaped square is larger than that of the' square-shaped square, the upper transverse partition plate 11 can be realized, and the 'short rectangular-square-shaped square can also be regarded as one of the' square-shaped square, but the invention is only an example and does not obstruct or limit the existence of other upper transverse partition plates 11 in various forms. The upper cross partition 11 of this shape can simultaneously maintain the transmission of force in the horizontal direction and does not block the communication of the corner steel pipes 21 in the vertical direction, thus having two advantages. Compared with the previous embodiment shown in fig. 2A and 2B, the preferred embodiment can use fewer vertical corner steel tubes 21, and the upper transverse partition plate 11 with the shape of the "truncated quadrangle" is adopted, so that the arrangement of the corner steel tubes 21 is possible. It should be noted that in fig. 2C, 2D and 5B, the column 100 includes an upper extension portion, which is more advantageous for the connection between different upper and lower columns without any limitation to the arrangement of the "off-square-shaped upper horizontal partition 11 and the" back-shaped lower horizontal partition 12 described herein, so that the upper extension portion of the column 100 is a preferred but not necessary way.

In another form of embodiment, as shown in fig. 2E, both the upper horizontal partition 11 and the lower horizontal partition 12 are in the shape of "short square and return" as shown in fig. 6A. By nature, in this preferred embodiment, the column 100 includes at least one diaphragm 1, the diaphragm 1 does not cover the corner steel tube 21 at the corner of the column 100, and the diaphragm 1 does not cover the columnar region 9 at all. The upper transverse partition plate 11 and the lower transverse partition plate 12 in the shape of the Chinese character 'wu-fang-hui' are exemplary, and do not obstruct or limit the existence of the upper transverse partition plate 11 in other various forms. The upper and lower

horizontal walls

11 and 12 having such a shape can simultaneously maintain the transmission of force in the horizontal direction, and do not block the communication of the corner steel pipes 21 in the vertical direction, thus having two advantages. Very particularly, in such an example, the corner steel tubes 21 may be completely uninterrupted by any of the upper and

lower bulkheads

11, 12, and thus may maintain optimal vertical length continuity. Like before, the upper and lower

horizontal diaphragms

11 and 12 of this shape can maintain the horizontal force transmission without breaking the corner steel pipes 21, so that the column 100 can receive the horizontal force of the outer beams 6 of both sides in a balanced manner, or the horizontal force can be smoothly transmitted through the column 100. It should also be noted that in fig. 2E, the column 100 includes an upper extension, which is more advantageous for the connection between the different upper and lower columns, and does not impose any limitation on the arrangement of the "truncated quadrangular pyramid" shaped upper cross partition 11 and the "truncated pyramid" shaped lower cross partition 12 described herein, so that the upper extension of the column 100 is a preferred, but not essential, form.

It should also be noted that in other embodiments, it is also possible that the diaphragms cover portions of the corner steel tubes at the corner positions of the columns, and that the diaphragms do not fully cover the columnar areas. The above two technical schemes are the intention of the invention and both are the protection scope of the invention.

According to fig. 2A, 3A, 5A, the manufacturing process of the pillar 100 under preferred conditions can be realized by the following preferred steps:

at S1, four corner steel pipes 21, each of which is a rectangular steel pipe, are arranged at the corner positions 20 of the column 100.

S2, corrugated side plates 3 are provided between the adjacent corner steel pipes 21. At this time, the corner steel pipe 21 and the corrugated side plate 3 together enclose a substantially rectangular parallelepiped columnar region 9.

And S5, arranging two criss-cross first drawknot plates 4, wherein two ends of each first drawknot plate 4 are respectively arranged on the corner steel tubes 21 at the opposite corners.

S6, providing side steel pipes 22 between the adjacent corner steel pipes 21 at the corner positions 20; between the side steel tubes 22 at least partially opposite the position 20, a second drawknot plate 42 is connected, preferably comprising two second drawknot plates 42, the two second drawknot plates 42 being arranged crosswise. At this time, S6 is combined with S5 to form a "m" shaped drawknot panel.

S3, arranging a transverse clapboard 1 in a shape of a Chinese character 'hui', namely an upper transverse clapboard 11 and a lower transverse clapboard 12. To connect the outer beams 6 and the columns 100, the columns 100 and the outer beams 6 are connected by welding and/or bolting, illustratively, where the columns 100 interface with the outer beams 6, the upper surface of the outer beams 6 is flush with the upper diaphragm plate 11, and the lower surface of the outer beams 6 is flush with the lower diaphragm plate 12. In some embodiments, as shown in fig. 2C and 2D, the upper horizontal partition plate 11 does not cover the corner steel tube 21 at the corner of the column 100, the lower horizontal partition plate 12 covers the corner steel tube 21 at the corner of the column 100, and the lower horizontal partition plate 12 is in a shape of a "square". In other embodiments, as shown in fig. 2E, at least one bulkhead 1 is provided such that the bulkhead 1 does not cover the corner steel tubes 21 at the corner positions of the column 100 and the bulkhead 1 does not fully cover the columnar areas 9.

S4, concrete 5 is poured into the columnar region 9, and concrete is not poured into the corner steel pipe.

It should be noted that the above-mentioned steps S1, S2, S3, S4, S5 and S6 do not represent that the steps with small numbers must be carried out first, which is merely a distinguishing mark, and there is no sense in chronological order. The preferred method of fabricating the pillars described above is exemplary, and many of the steps are preferred, and one skilled in the art will readily appreciate that these steps or certain features of the steps are not required.

The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
