Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a method for installing a special-shaped prefabricated plain concrete colonnade. Background Art

[0002] Special-shaped concrete colonnades refer to colonnade structures constructed using concrete columns and beams of non-traditional geometric shapes. Their design focuses more on visual impact and uniqueness while taking into account practical functions. Special-shaped colonnades break the form of traditional square and round columns and often present complex curved surfaces, twisted or dynamic shapes. They are an important embodiment of innovative design in modern architecture.

[0003] The existing construction method of special-shaped concrete colonnades is generally: formwork production and installation - steel bar binding - concrete pouring - surface correction. However, during the construction of complex colonnades, the above construction method is prone to problems such as formwork leakage, column deformation, many pouring bubbles and joint cracking, which makes the construction difficult and the construction efficiency low. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a method for installing a special-shaped prefabricated plain concrete colonnade, which solves the problems of great construction difficulty and low construction efficiency of the special-shaped concrete colonnade in the prior art.

[0033] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0034] like Figure 1 As shown, an embodiment of the present invention provides a method for installing a special-shaped prefabricated plain concrete colonnade, comprising the following steps:

[0035] S1. Design, production and transportation of prefabricated columns, prefabricated parapet panels, prefabricated beams and prefabricated panels;

[0036] S2. Laying out and positioning at the construction site;

[0037] S3. Prefabricated column hoisting and acceptance;

[0038] S4. Installation and acceptance of prefabricated parapet panels;

[0039] S5. Installation and acceptance of prefabricated beams;

[0040] S6. Precast panels are hoisted to complete the installation of special-shaped precast plain concrete colonnades.

[0041] Preferably, in step S3, the specific method of hoisting the prefabricated column is:

[0042] S31. Soft materials are laid on the working ground of the prefabricated column placement area, and each corner of each prefabricated column needs to be wrapped and protected with bubble film corner protectors;

[0043] S32. Lift one end of the prefabricated column by a crane so that the other end of the prefabricated column is supported on a soft material and the prefabricated column is rotated to a vertical direction;

[0044] S33. Move the prefabricated column to the top of the cup-mouth foundation and slowly lower it so that the prefabricated column is installed in the cup-mouth foundation. In the process of lowering, first slowly lower it to 0.5m from the top surface of the cup-mouth foundation, then use manual assistance to correct the position and continue to slowly lower it to ensure that the prefabricated column can be accurately installed in the corresponding cup-mouth foundation;

[0045] S34. Cast between the prefabricated column and the cup-shaped foundation to complete the fixed installation of the prefabricated column.

[0046] Preferably, the prefabricated columns are divided into two types: those connected to the cast-in-place structure and those not connected to the cast-in-place structure. During the hoisting process, the prefabricated columns connected to the cast-in-place structure need to be hoisted first, and then the prefabricated columns not connected to the cast-in-place structure need to be hoisted; among them, the prefabricated columns connected to the cast-in-place structure need to be welded and fixed between the prefabricated columns and the embedded parts of the cast-in-place structure through connecting plates after completing step S33, and the position of the prefabricated columns needs to be corrected before performing step S34.

[0047] Preferably, in step S4, the specific method for hoisting the prefabricated parapet hanging plate is:

[0048] S41. Lift the prefabricated parapet panels by crane and special lifting equipment and keep them level. The special lifting equipment is a horizontally arranged lifting beam. When lifting the prefabricated parapet panels, first lift them 50 cm from the ground, check the balance of the prefabricated parapet panels and the firmness of the lifting points, and then lift them to the installation height.

[0049] S42. Move the prefabricated parapet hanging panels to corresponding areas on top of several prefabricated columns for installation.

[0050] Preferably, in step S5, the specific method of hoisting the prefabricated beam is:

[0051] S51. Lift the prefabricated beam by crane and keep it horizontal, avoiding prefabricated columns, prefabricated parapet slabs, cup-shaped foundations and cast-in-place structures. Use a sling to fix one end of the prefabricated beam 1.5m away from its end, and connect a pull rope;

[0052] S52. Lift the prefabricated small beam to the installation position and install it; during the lifting process of the prefabricated small beam, pull the prefabricated small beam by operating the pull rope to tilt it so as to avoid other prefabricated components and cast-in-place structures and accurately move it to the installation position.

[0053] Preferably, in step S6, the specific method of hoisting the prefabricated panels is to install the prefabricated panels on corresponding prefabricated beams.

[0054] Preferably, when inspecting prefabricated columns, prefabricated parapet panels and prefabricated small beams, the positions and elevations need to be reviewed for acceptance, and offset adjustments need to be made for positions that do not meet the design standards.

[0055] Moreover, after the prefabricated columns and prefabricated parapet panels are hoisted, temporary supports need to be installed to ensure the stability of the supports of the prefabricated columns and prefabricated parapet panels during the subsequent installation process. After the overall installation of the subsequent special-shaped prefabricated plain concrete colonnade is completed, the temporary supports can be dismantled and recycled.

[0056] The prefabricated columns, prefabricated parapet panels, prefabricated beams and prefabricated panels are all installed by means of embedded parts connection. The specific structure, connection principle and components involved in the embedded parts connection are all existing technologies and will not be described in detail here.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
