Description

One-piece Construction Method of Scaffolding System

technical field

The invention relates to the field of building construction, in particular to an integrated construction method of a bracket system.

Background technique

As more and more buildings appear in various cities, the number and types of building brackets are also increasing. At present, the most commonly used support systems in my country include portal scaffolding, bowl-buckle scaffolding, socket-type scaffolding and fastener-type steel pipe scaffolding.

At present, the general calculation method of support system is based on independent structural components, such as beams, slabs, columns, walls, etc., to carry out independent checking calculations of bearing capacity, stability, and stiffness, and generate respective support design schemes. But for actual engineering, the support system of the structure is often a whole, not just a support system of a single component. Therefore, in the actual project implementation process, the designer often needs to calculate the support of each component System design parameters are converted into design drawings and large-scale drawings to guide on-site construction according to construction experience. Due to the uneven level of technicians in the support engineering construction units, there are often many problems in the calculation books and design drawings of the support system. Especially for structural engineering with complex geometric shapes, it is even more difficult to provide design drawings and large-scale drawings that can effectively guide on-site construction by the current general-purpose calculation method based on independent structural components, which leads to a disconnect between design and construction and causes engineering accidents.

The disadvantages of the prior art are:

1) Poor security: Affected by the geometric shape of the concrete structure, the support system used to bear the self-weight of the structure during concrete pouring and maintenance often does not bear the force in one direction, but bears the combined force in multiple directions at the same time. Therefore, the current calculation method only considers the one-way force of the support system, and there is a problem of missing items in the design check calculation items.

2) The degree of intelligence is low: the calculation adopts the trial calculation mode, and the design parameters of the support are manually determined for checking calculation to determine whether the support system is safe. If the checking calculation fails, it is necessary to modify the design parameters and then check the calculation until the checking calculation is passed. For the design schemes that have passed the checking calculation, it is also necessary to make judgments based on experience and analyze their economy and practicability. Because the calculation is greatly affected by human factors, the efficiency of its design calculation is low, the degree of intelligence is not enough, and the economy is difficult to achieve optimal.

3) Poor operability: the design of the support system with a single component as the object will cause the support system of each component to fail to connect well at the interface. On-site operations can only be designed and erected based on experience, and most In the accident case, it is precisely these parts that are the first to be at risk and lead to the collapse of the entire support system.

Therefore, how to establish a scaffold system construction method with high degree of intelligence, strong practicability, safety and economy is an urgent problem to be solved in this field.

Referring to Fig. 1, the integrated construction method of the stent system of the present invention includes:

S101 Draw a cross-sectional geometric figure of a building structure that needs to be designed with a support system, and import the cross-sectional geometric figure into a graphics processing system.

Fig. 2 is a schematic structural view of the cross-sectional geometric figure in a preferred embodiment of the integrated construction method of the stent system of the present invention. As shown in Fig. 2, the section information of the cross-sectional geometric figure is in the form of multiple closed polylines It means that the cross-section geometric figure includes a closed cross-section outer frame and a cross-section boundary line formed inside the cross-section outer frame, and a cross-section entity is between the cross-section outer frame and the cross-section boundary line.

S102 , the graphic processing system identifies the type of each component in the cross-sectional geometric graphic.

Fig. 3 is a schematic diagram of the structure of the preferred embodiment of the integrated construction method of the stent system of the present invention after the identification of the section geometry is completed. As shown in Fig. 3, after the section geometry is imported into the graphics processing system, the graphics The processing system recognizes the section outer frame of the section geometric figure through the interval size, and then recognizes the component type (wall, oblique axillary, plate, beam) of each section block according to the coordinate points of the internal section boundary line of the section geometric figure . The specific identification process is as follows:

Step 1: The graphics processing system records the coordinate points of each node on the boundary line of the section, and the coordinate points of the nodes are represented by X _n and Y _n , as shown in Figure 2, at the boundary of the section The 14 nodes A ₁ (X ₁ , Y ₁ ) to A ₁₄ (X ₁₄ , Y ₁₄ ) are marked on the line.

Step 2: Identify from the left corner of the section boundary line, compare the relationship between the coordinate points of each node, and determine the type of component formed by each node.

Step 3: When the relationship between the coordinate points of two adjacent nodes satisfies X _n = X _n-1 , Y _n ≠ Y _n-1 , identify the type of the component formed between the two adjacent nodes for the wall. As shown in FIG. 2 , the component composed of A ₁ node and A ₂ node, and A ₁₃ node and A ₁₄ node is identified as the wall 10 . Wherein, the difference between the vertical coordinates of node A ₁ and node A ₂ and the difference between the vertical coordinates of node A ₁₃ and node A ₁₄ is the height of the wall 10 .

Step 4: When the relationship between the coordinate points of two adjacent nodes satisfies X _n ≠ X _n-1 , Y _n ≠ Y _n-1 , identify the type of the component formed between the two adjacent nodes For oblique axillary. As shown in Fig. 2, the member formed by node A ₂ and node A ₃ , and node A ₁₂ and node A ₁₃ is identified as the oblique axillary 20.

Step 5: When the relationship between the coordinate points of two adjacent nodes satisfies X _n ≠ X _n-1 , Y _n = Y _n-1 , identify the type of the component formed between the two adjacent nodes for the board. As shown in FIG. 2 , the component composed of node _A3 and node _A4 , node _A7 and node _A8 , and node _A11 and node _A12 is identified as the plate 30.

Step 6: When the relationship between the coordinate points of the four adjacent nodes satisfies X _n+1 ＝X _n , Y _n+1 ≠Y _n , X _n ≠X _n-1 , Y _n ＝Y _n-1 , X When _n-1 =X _n-2 , Y _n-1 ≠Y _n-2 , the type of the member formed between the four adjacent nodes is identified as a beam. As shown in FIG. 2 , the member composed of node _A4 , node _A5 , node _A6 and node _A7 , and node _A8 , node _A9 , node _A10 and node _A11 is identified as the beam 40.

After the identification is completed, the wall 10 , the oblique axil 20 , the board 30 and the beam 40 are identified by different colors, as shown in FIG. 3 .

In S103, load calculation is carried out on the member whose type identification has been completed as a single object, and the standard safety degree index of a single member is obtained.

Take a single slab, beam, and wall as a single calculation object, and use different calculation formula groups for calculation according to their different characteristics. In the calculation, the support material (bottom form material, _main flute material, etc.), structural physical parameters (such as: thickness, clear height, _etc. ) ) is the basic value, and the longitudinal distance of the vertical pole, the transverse distance of the vertical pole, and the spacing of the secondary corrugations are the trial calculation parameters, and the standard safety index of a single component that meets the safety conditions is obtained. The standard safety degree refers to the bending strength, shear strength, vertical rod stability etc. The standard safety indicators such as bending strength, shear strength, and pole stability in the calculation results are used as the check value of the support system. When the safety factors all meet the safety conditions (value ≥ 1), it means that the support material meets the support requirements, and when the safety factors do not meet the safety conditions (value < 1), an alarm is sent to the user.

S104 , according to the cross-sectional geometry and the identified component type, constructing a support system with the building structure as an overall object.

S105 performs coupling calculation on the support parameters of the support system, and adjusts the support parameters, so that the support parameters meet the standard safety indicators of all individual components.

Wherein, the support parameters of the support system are coupled and calculated, and the support parameters are adjusted so that the support parameters meet the standard safety indicators of all individual components, including the following three situations:

(1) The wall adopts truss steel formwork, the wall is not calculated, and it does not have any impact on the calculation of other parts. The support parameters include three trial calculation parameters of the longitudinal distance of the vertical pole, the horizontal distance of the vertical pole and the step distance of the non-top vertical pole section, and the calculation steps include:

Feedback the vertical distance of the vertical rod of the beam after adjustment to the board, so that the vertical distance of the vertical rod of the board is consistent with the vertical distance of the vertical rod of the beam;

When the wall adopts the truss steel formwork method, the support parameters satisfying the safety index of all single member codes are obtained.

(2) The wall adopts the double pull method, and the wall body is calculated separately, and the resulting value is only used for the wall body itself. The support parameters include three trial calculation parameters of the longitudinal distance of the vertical pole, the horizontal distance of the vertical pole and the step distance of the non-top vertical pole section, and the calculation steps include:

Carrying out load calculation on the support parameters of the wall and adjusting the trial calculation parameters of the wall, so that the support parameters of the wall meet the specification safety index of the wall, first separately obtaining the support parameters of the wall;

The longitudinal distance of the vertical rod of the beam and the step distance of the non-top vertical rod section are set to be consistent with the vertical distance of the vertical rod of the plate and the step distance of the non-top vertical rod section;

Using the vertical bar transverse distance of the plate as the initial value of the vertical bar transverse distance of the beam, the load calculation is carried out to the support parameters of the beam, and when the stability calculation cannot be satisfied, the vertical bar transverse distance of the beam is first adjusted, When adjusting the horizontal distance of the vertical bar of the beam can not satisfy the stability calculation all the time, then adjust the vertical distance of the vertical bar of the beam instead, so that the support parameters of the beam meet the standard safety index of the beam;

(3) The wall adopts the way of supporting, which has a direct impact on the calculation of the slab and beam. The support parameters include three trial calculation parameters of the longitudinal distance of the vertical pole, the horizontal distance of the vertical pole and the step distance of the non-top vertical pole section, and the calculation steps include:

Carrying out load calculation on the support parameters of the wall and adjusting the trial calculation parameters of the wall, so that the support parameters of the wall meet the specification safety index of the wall;

Select the smaller value in the vertical distance between the board and the wall, and the smaller value in the vertical distance between the board and the wall, as the vertical distance between the board and the wall distance and the final determined value of the longitudinal distance of the pole;

The longitudinal distance of the vertical rod of the beam and the step distance of the non-top vertical rod section are set to be consistent with the vertical distance of the vertical rod of the plate and the step distance of the non-top vertical rod section;

Using the vertical bar transverse distance of the plate as the initial value of the vertical bar transverse distance of the beam, the load calculation is carried out to the support parameters of the beam, and when the stability calculation cannot be satisfied, the vertical bar transverse distance of the beam is first adjusted, When adjusting the horizontal distance of the vertical bar of the beam can not satisfy the stability calculation all the time, then adjust the vertical distance of the vertical bar of the beam instead, so that the support parameters of the beam meet the standard safety index of the beam;

When the wall is braced in the opposite way, the support parameters that meet the safety index of all individual component codes are obtained.

Due to too many calculation parameters involved in the calculation process, the calculated design scheme is usually not unique. Therefore, the selection and adjustment of the optimal design scheme will be awakened during the calculation process. Generally, the support parameters include a plurality of trial calculation parameters, and the support parameters of the support system are coupled and calculated by the forward derivation method and the incremental method. The analysis process is mainly through forward derivation, that is, all trial calculation parameters The value is incrementally incremented according to the incremental value, and all the parameter values of each trial parameter increased by one incremental value are combined as a group of schemes. After comparing the optimal scheme in a group, continue to repeat the incremental value incremental trial calculation. The parameter value combination scheme after each trial calculation parameter increment needs to be calculated 2 ⁿ -1 times, where n is the number of trial calculation parameters, and the optimal combination is determined and taken out according to the check value, that is, multiple The trial calculation results in which the trial calculation parameters all meet the normative safety index of any single component are taken as the optimal combination.

Here, taking the anti-skid type of fasteners as an example for the bottom mold support type of the slab, the trial calculation parameters are: longitudinal distance of vertical poles, horizontal distance of vertical poles, distance between secondary corrugations, and step distance of non-top vertical poles, a total of 4 items. Then, The calculation process includes specifically including:

Step 1: providing an initial value, assigning the initial value to a plurality of the trial calculation parameters;

Provide the first incremental value a ₁ , use the binary method to perform 2 ⁴ -1=15 trial calculations on a plurality of trial calculation parameters, where n is the number of trial calculation parameters, and among the 15 trial calculation results Selecting a first optimal combination, assigning the parameter value _A1 of the first optimal combination to a plurality of the trial calculation parameters;

The use of the binary method described therein, for example, the binary method of the first calculation is expressed as 0001, which means that only the first trial calculation parameter vertical distance is incremented, and other trial calculation parameters are not incremented;

For example, the binary method of the third calculation is expressed as 0011, indicating that the first trial calculation parameter vertical distance of the vertical pole and the second trial calculation parameter vertical distance of the vertical pole are incremented together, and other trial calculation parameters are not incremented;

For example, the binary method of the 7th calculation is expressed as 0111, which means that the first trial calculation parameter vertical distance of the pole, the second trial calculation parameter vertical distance of the vertical pole and the third trial calculation parameter of the second flute spacing are increased together. amount, other trial calculation parameters will not be incremented;

For example, the binary method of the 15th calculation is expressed as 1111, which means the vertical distance of the vertical pole of the first trial calculation parameter, the horizontal distance of the vertical pole of the second trial calculation parameter, the second flute spacing of the third trial calculation parameter and the fourth trial calculation parameter The four parameters of step distance of the non-top vertical pole section are incremented together, and other trial calculation parameters are not incremented;

Step 2: Provide the second incremental value a ₂ , use the binary method to perform 2 ⁴ −1=15 trial calculations on a plurality of trial calculation parameters assigned to the parameter value A ₁ , the results of 15 trial calculations Select a second optimal combination among them, and assign the parameter value _A of the second optimal combination to a plurality of the trial calculation parameters;

Step 3: Provide a third incremental value a ₃ , use the binary method to perform 2 ⁴ −1=15 trial calculations on a plurality of trial calculation parameters assigned to the parameter value A ₂ , and the results of the 15 trial calculations Select a 3rd optimum combination among them, assign the parameter value _A of the 3rd optimum combination to a plurality of described trial calculation parameters;

Step 4: Repeat the above steps by incremental method until when the mth incremental value a _m is provided for trial calculation, any of the trial calculation parameters do not meet the standard safety index of any of the individual components, stop trial calculation;

Step 5: The parameter value A m- ₁ of the m-1th optimal combination is used as the final determined value of the multiple trial calculation parameters to obtain support parameters that meet the safety index of all single component specifications.

In addition, the main control item intervention can also be introduced in the analysis, that is, the primary and secondary status of each trial calculation parameter in the derivation can be obtained by setting and calculating according to the safety importance and economic efficiency in the actual application, so that the importance of each parameter in the derivation process can be obtained. The nodes are in their due influence and role, helping the support system to select and adjust in a better direction.

It is also possible to manually adjust the arrangement of supports at local locations, and check the safety of the modified support system. The optimal design scheme formed, by calling the finite element calculation program, carries out the numerical analysis of the support system of the entire structural section, further judges the safety of the support system, and verifies the safety of the support system in key parts bearing multi-directional loads.
