The vertical plane formed by two adjacent upright posts 1 means that the two upright posts 1 have four end points, and the four end points form a vertical plane which is parallel to the vertical plane.
The L-shaped beams 2 are horizontally arranged and are located in different vertical planes, and the heights of the L-shaped beams 2 are in one-to-one correspondence, and it is easy to understand that the four upright posts 1 are distributed in a square shape, so that the number of the L-shaped beams 2 located at the same height in the construction platform structure of the embodiment is four.
The cross braces 3 are disposed on the upper and lower sides of each L-shaped beam 2, and of course, the cross braces 3 are disposed only with respect to one L-shaped beam 2, that is, the cross braces 3 disposed on the lower side of the upper layer L-shaped beam 2 and the cross braces 3 disposed on the upper side of the lower layer L-shaped beam 2 are the same group of cross braces 3.
Two ends of the cross brace 3 are fixed on one upright 1, the other two ends are fixed on the other adjacent upright 1, the cross brace 3 is formed by intersecting two independent braces, two ends of the same brace are respectively connected to the two adjacent uprights 1, and tensile strength is provided for the whole construction platform structure, as shown in fig. 4, the cross brace 3 is also abutted against and connected to the L-shaped beam 2 while the cross brace 3 is connected with the upright 1, so that force transmission is further improved, excessive concentration of stress is avoided, and the whole construction platform structure has good stability.
The top of the upright 1 is connected with a cap 4, the cap 4 is of a plate-shaped structure and is in close contact connection with the top surface of the upright 1, the top of the cap 4 is connected with a bearing plate 5, the bearing plate 5 can be used for supporting large-scale equipment or for other construction needs, the upright 1 is connected with the bearing plate 5 through the cap 4, the contact area between the upright 1 and the bearing plate 5 can be enlarged, the pressure intensity between the upright and the bearing plate is reduced, and deformation of the bearing plate 5 is avoided.
As shown in fig. 6 and 7, the cross section of the upright 1 is rectangular, and the interior of the upright 1 is hollow. The inner wall of the upright 1 is connected with a plurality of first stiffening ribs 11 along the length direction of the upright 1, and the interval between two adjacent first stiffening ribs 11 increases gradually from the top of the upright 1 to the bottom of the upright 1.
For example, in the present embodiment, the cross section of the upright 1 is square, and six first stiffening ribs 11 are provided inside the upright 1, the distances between two adjacent first stiffening ribs 11 in the six first stiffening ribs 11 are L1, L2, L3, L4, and L5, respectively, and l2=2xl1, l3=3xl1, l4=4xl1, l5=5xl1, and the distances between the first stiffening rib 11 at the head and the top of the upright 1, and the distances between the first stiffening rib 11 at the tail and the bottom of the upright 1 are all not greater than L1. Through the arrangement mode, the integral strength of the upright post 1 can be enhanced while the integral quality of the construction platform structure is reduced, and especially the strength of the top of the upright post 1 is enhanced, so that the torsion resistance of the upright post 1 is improved. It will be readily appreciated that where the spacing between two adjacent first stiffening ribs 11 is satisfied to increase from the top of the stud 1 to the bottom of the stud 1, the manner of increasing and the amount of increasing is not strictly limited. Likewise, more first ribs 11 can be connected to the inside of the column 1 to accommodate higher load requirements.
As shown in fig. 8, the L-shaped beam 2 includes a horizontal plate 22, and a vertical bending portion 21 connected to a side edge of the horizontal plate 22 and extending in a longitudinal direction of the horizontal plate 22 itself, wherein a length of the horizontal plate 22 is smaller than a length of the vertical bending portion 21. A second stiffening rib 23 is connected between the horizontal plate 22 and the vertical bending part 21, and the second stiffening rib 23 is positioned in the middle area of the L-shaped beam 2. In this embodiment, taking three second stiffening ribs 23 as an example, a first second stiffening rib 23 is disposed at the middle position of the L-shaped beam 2, and two other second stiffening ribs 23 are respectively disposed at the left and right sides of the second stiffening rib 23 at the middle position at equal intervals. Likewise, more second stiffening ribs 23 may be attached to the interior of the L-beam 2 to accommodate higher load demand construction.
As shown in fig. 9 and 10, which show the connection manner of the L-shaped beams 2 and the upright posts 1, two ends of the horizontal plate 22 are respectively connected with the opposite surfaces of two adjacent upright posts 1, the vertical bending parts 21 are in abutting connection with the outer side surfaces 12 of the upright posts 1 adjacent to the opposite surfaces 13, and the two adjacent L-shaped beams 2 are mutually perpendicular and connected end to end in the L-shaped beams 2 with the same height in different vertical planes.
Specifically, according to the position of the L-shaped beam 2 in the construction platform structure, the L-shaped beam 2 is divided into a wide L-shaped beam and a long L-shaped beam, wherein a wide horizontal plate 221 and a long horizontal plate 221 in the wide L-shaped beam and the long L-shaped beam are horizontally arranged in connection and are positioned between two adjacent upright posts 1, and the end surfaces are connected with opposite surfaces 13 of the upright posts 1; the wide vertical bending part 211 and the long vertical bending part 212 are vertically arranged in connection and are positioned at the outer edges of two adjacent upright posts 1, and the surfaces of the wide vertical bending part and the long vertical bending part are abutted against the outer side surfaces 12 of the upright posts 1. In this embodiment, the opposite surfaces 13 of the columns 1 are opposite sides of two adjacent columns 1, and the outer side surfaces 12 are surfaces of the columns 1 except for the opposite surfaces 13, and since four columns 1 are distributed in a square shape, two adjacent opposite surfaces 13 and two adjacent outer side surfaces 12 are provided on the same column 1.
Because the length of the horizontal plate 22 is smaller than the length of the vertical bending portion 21, as shown in fig. 10, the wide vertical bending portion 211 and the long vertical bending portion 212 are longer than the wide horizontal plate 221 and the long horizontal plate 222 by a length of L6 plus L7, the length of L7 is the side length of the square of the cross section of the upright post 1, and the length of L6 is the sum of the length of L7 and the thickness of the wide vertical bending portion 211 or the long vertical bending portion 212, so that in the connection between the L-shaped beam 2 and the upright post 1, the wide vertical bending portion 211 and the long vertical bending portion 212 are connected end to improve the integrity of the construction platform structure and optimize the transmission of force.
The material of construction platform structure is one or more in bamboo material, wooden material and the aluminium system material, and adopts rigid connection mode such as bolt, welding between each part in the construction platform structure to make the construction platform structure that this embodiment provided, its overall quality is lighter, is convenient for build, and the intensity and the stability of structure are high. It is easy to understand that, in order to realize the requirements of portability and high strength, the construction platform structure designed in this embodiment adopts bamboo materials, wooden materials and aluminum materials, and when the requirements of the construction platform on strength and high load are higher, and the overall quality of the construction platform is not strictly required, the material of the construction platform structure in this embodiment may also be a material with higher strength such as steel and iron.
According to the technical scheme, the construction platform structure is subjected to stress analysis and verification through the following specific loading test.
Example 1: load test
In the manufacturing of the model structure, the upright post adopts a hollow bamboo rod with the cross section dimension of 8mm x 8mm, and the wall thickness of the hollow bamboo rod is 0.5mm; the L-shaped beam adopts an L-shaped bamboo pole with the cross section dimension of 5mm x 5mm and the thickness of 1 mm; the cross brace adopts bamboo strips with the cross section size of 1mm and 2 mm; the thickness of the first stiffening rib and the second stiffening rib is 2mm, and the distance between two adjacent first stiffening ribs or second stiffening ribs is 4mm; the column cap adopts a rectangular bamboo pole with the thickness of 1mm. And the bamboo pole adopts an integrated bamboo pole with the density of 0.789g/cm < 3 >, the grain-oriented tensile strength of 150MPa, the compressive strength of 65MPa and the elastic modulus of 10 GPa.
And (5) properly polishing the lap joint parts of the components, bonding the lap joint parts by using 502 glue, and filling and tamping a part of the joint gaps of the components with a proper amount of bamboo powder. The overall dimensions of the mould structure were 503mm high, 500mm long and 300mm wide.
And (3) carrying out calculation analysis on the model structure:
as shown in fig. 11, in a plan view of the model structure, four columns are numbered in sequence, and calculation analysis is performed for each column.
In the loading test, two persons weighing 70kg and 65kg respectively stand on the model structure, and in an ideal state, the persons act on the four columns as concentrated loads:
G＝m1g+m2g＝70×9.8+65×9.8＝1323N；
The forces on the four columns are: f 1＝F2＝F3＝F4 =1323/4= 330.75N;
Deformation amount: Wherein A is the sectional area of the upright post;
Stress:
The calculation can obtain that when two persons apply force to the model structure in an ideal state, the model structure has no fracture or collapse phenomenon, and the strength and the stability of the structure are high.
In the loading test, two persons with the weights of 70kg and 65kg respectively stand on the model structure, and in the actual state:
according to the loading mode of taking the person as the load, the left foot is more in force, 80% of gravity is taken at the left foot, 20% of gravity is taken at the right foot, the left foot adopts a concentrated load mode, and the right foot adopts uniformly distributed loads.
1) The load distribution is shown in fig. 12, and the calculation that the load acts on the model structure is as follows:
the first person: g 1 =70 kg×9.8n/kg=686n;
0.8G1＝0.8×70×9.8＝548.8N；
0.2G1＝0.2×70×9.8＝137.2N；
A second person: g 2 =66 kg×9.8n/kg= 646.8N;
0.8G2＝0.8×66×9.8＝517.44N；
0.2G2＝0.2×66×9.8＝129.36N；
2) The Y-axis load distribution in front view is shown in fig. 13:
Moment taking for the point A is as follows:
∑Me＝548.8×15+8.63×15÷2-517.44×15-9.15×15÷2×15＝-494.25N/cm
from the calculation, the Y-axis load distribution condition F y =37.07N can be obtained
3) The load to which the left and right columns are subjected is calculated as shown in fig. 14:
(G1+G2)·X+Me＝0
F Left side +F Right side ＝G1+G2
X＝494.25/[(70+66)×9.8]＝3.71mm
then, F Right side ＝650N;F Left side = 682.8N.
4) The load distribution of the two columns in the left view is shown in fig. 15:
According to the analysis of the practical situation, in order to keep balance, the center of gravity is forward, so the column connected with the front foot (i.e. column one 6) has larger bearing force, and 60% of the load is applied to column one 6:
0.6F Left side ＝0.6×682.84N＝409.7N；
0.4F Left side ＝0.4×682.84N＝273N；
F Left side ·2+MB =0; therefore, X 0 =20mm in the figure can be obtained; and is also provided with
FN3＝273.12N；
FN1+FN3＝F Left side ;FN1＝409.7N；
5) The load distribution of the two columns in the right view is shown in fig. 16:
According to the analysis of practical situation, in order to keep balance, the center of gravity is forward, so the upright column (i.e. column number four 8) connected with the front foot has larger bearing force, and 60% of load is applied to column number four 8:
0.6F Right side ＝0.6×650N＝390N；
0.4F Right side ＝0.4×650N＝260N；
And (3) the same principle:
F Right side ·X+MD =0; therefore, X 0 =20mm in the figure can be obtained; and is also provided with
FN2＝260N；
FN4+FN2＝F Right side ;FN4＝390N；
6) To sum up the above calculations:
FN1＝409.7N;FN2＝260N;FN3＝273.12N;FN4＝390N。
therefore, in the overall model structure, the strength and rigidity of the four columns are obtained as follows.
Intensity:
Column number one 6:
Column No. 7:
column No. 9:
column number four 8:
Stiffness:
Column number one 6:
Column No. 7:
column No. 9:
column number four 8:
it can be seen that the model structure of the present embodiment has sufficient structural strength and rigidity.
The stability analysis was performed on the model structure as follows:
since the first column 6 and the fourth column 8 are highly stressed in order to maintain balance when a person stands up, these two columns may be considered.
Column number one 6:
A＝8×8＝64mm2；
ix＝0.4h＝0.4×8＝3.2mm;iy＝0.4h＝0.4×8＝3.2mm；
lox＝loy＝17cm；
Because of the large value of the slenderness ratio of the x-axis and y-axis, the ratio:
x-0.623＝9×(0.616-x)；x-0.623＝5.544-9x；
10x＝6.167；
x＝0.6167；
The stability of column number one 6 is sufficient.
Column number four 8:
A＝8×8＝64mm2；
ix＝0.4h＝0.4×8＝3.2mm;iy＝0.4h＝0.4×8＝3.2mm；
lox＝loy＝17cm；
larger values of slenderness ratio of the x-axis and y-axis, so
x-0.623＝9×(0.616-x)；
x-0.623＝5.544-9x；
10x＝6.167；
x＝0.6167；
