Description

Technical Field

[0001] This invention relates to the technical field of building construction, and in particular to a European-style building support construction method. Background Technology

[0002] European-style arch structures are aesthetically pleasing, but they are not easy to construct. Large cast-in-place concrete arch structures are generally used in bridge construction because they are not used in building construction. Small cast-in-place concrete arch structures are difficult to construct and are not suitable for use in building construction. However, if you want to incorporate European-style arch structures, you need to overcome the difficulty of constructing small cast-in-place concrete arch structures. Summary of the Invention

[0003] To reduce construction difficulty and add an aesthetically pleasing arched structure to the building, this invention provides a European-style building support construction method.

[0004] The present invention provides a European-style building support construction method using the following technical solution:

[0005] A European-style building construction method for upper-bearing structures includes the following steps:

[0006] Erect and pour concrete for the frame columns and frame beams;

[0007] Install the arched bottom formwork;

[0008] Filling the triangular area with masonry;

[0009] Wall painting;

[0010] Exterior wall painting.

[0011] By adopting the above technical solution, an arched template is installed, and the triangular area between the arched template and the frame beam and frame column is filled to connect the entire arch, thereby realizing the arched shape on the building surface. Moreover, the arched template can be made into templates of any size to adapt to any construction structure. Finally, the wall surface and exterior wall are painted to achieve an aesthetically pleasing appearance.

[0012] Preferably, in the step of erecting and pouring the frame columns and frame beams:

[0013] The precast frame beams and columns are made of steel bars and concrete. The precast frame beams and columns are brought to the construction site and then cast together.

[0014] Preferably, the step of installing the arched bottom formwork includes: prefabricating the arched formwork, installing the arched formwork support, and pouring the arched formwork.

[0015] The precast arch template is made of double-layer fair-faced concrete plywood. The number of precast arch templates is greater than or equal to the number of double-layer fair-faced concrete plywood. If the number of precast arch templates is greater than the number of double-layer fair-faced concrete plywood, the complete double-layer fair-faced concrete plywood is cut first, and the scraps are spliced ​​together to form a new arch template.

[0016] Preferably, A8@200 steel bars are used to bend along the shape of the arched template and connected laterally with column anchor bars to prefabricate the arched steel bars. The arched steel bars are then fixed to the arched template to form the arched template.

[0017] Preferably, the arched formwork support is constructed using A48.3×3.6mm coupler-type steel pipes. The horizontal and vertical spacing of the coupler-type steel pipes is between 500mm and 700mm, and the step distance is between 800mm and 1000mm. Shear bracing is arranged according to the high support formwork specifications.

[0018] Preferably, the arch formwork is erected on an arch formwork support structure, the arch formwork support structure supports the arch concave surface, the arch reinforcing bars are connected to the fastener-type steel pipes using fasteners, and self-compacting concrete is used to pour the arch reinforcing bars inside the arch formwork.

[0019] Preferably, in the triangular area masonry filling step: the filling masonry uses ordinary autoclaved aerated concrete blocks with a dry density grade of B05 and a strength grade of A3.5.

[0020] Preferably, in the wall painting step, the wall surface is painted with cement mortar with a water:sand ratio of 1:3.

[0021] Preferably, the exterior wall painting is carried out using real stone paint.

[0022] In summary, the present invention has the following beneficial technical effects:

[0023] 1. By installing an arched formwork and filling the triangular area between the arched formwork and the frame beams and columns, the entire arch is connected, thus achieving an arched shape on the building surface. The arched formwork can be made into any size to adapt to any construction structure. Finally, the walls and exterior walls are painted to achieve an aesthetically pleasing appearance. Attached Figure Description

[0024] Figure 1 This is an overall diagram of a European-style building support construction method according to the present invention. Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] This invention discloses a method for constructing European-style buildings using a top-supported structure. (Refer to...) Figure 1 The method includes taking the following steps:

[0027] First, the frame columns and beams are erected and cast. Precast steel and concrete frame beams and columns are then transported to the construction site, saving time and allowing for prefabrication. Once at the construction site, the frame beams and columns are cast together to form a unified external support structure.

[0028] Then the arched bottom formwork is installed. The steps of installing the arched bottom formwork include: prefabricating the arched formwork, installing the arched formwork support, and pouring the arched formwork.

[0029] The precast arch formwork is made of double-layer fair-faced concrete plywood. The number of precast arch formwork is greater than or equal to the number of double-layer fair-faced concrete plywood. If the number of precast arch formwork is greater than the number of double-layer fair-faced concrete plywood, the complete double-layer fair-faced concrete plywood is cut first, and the scraps are spliced ​​together to form a new arch formwork.

[0030] Finally, using a splicing method can make full use of the remaining scraps and save on construction costs.

[0031] A8@200 steel bars are bent along the shape of the arched template and connected laterally with column anchor bars to prefabricate the arched steel bars. The arched steel bars are then fixed to the arched template to form the arched formwork.

[0032] Arched formwork supports were installed on the frame beams and columns, constructed using A48.3×3.6mm coupler-type steel pipes. The horizontal and vertical spacing of the coupler-type steel pipes was between 500mm and 700mm, and the step distance was between 800mm and 1000mm. In the completed construction plan, the horizontal and vertical spacing was 600mm, and the step distance was 900mm. Because the arch beam cross-section was 800mm*1500mm, which is an ultra-heavy formwork support, shear bracing had to be arranged according to the high-support formwork specification, which is an industry-standard construction standard.

[0033] Casting an arched formwork involves erecting the arched formwork on an arched formwork support structure, with the support structure extending into the concave surface of the arch. The arched reinforcing bars are connected to the steel pipes using fasteners, and self-compacting concrete is used to pour the arched reinforcing bars inside the arched formwork.

[0034] Next, the triangular area is filled with masonry. The triangular area is the triangular gap formed between the arched formwork, the frame beam, and the frame column. The filling masonry uses ordinary autoclaved aerated concrete blocks with a dry density grade of B05 and a strength grade of A3.5.

[0035] Next, apply cement mortar with a water-to-mud-sand ratio of 1:3 to the wall surface; finally, apply stone-like paint to the exterior wall.

[0036] The implementation principle of a European-style building support construction method according to an embodiment of the present invention is as follows: An arch-shaped formwork is cut using double-layer fair-faced concrete plywood. Reinforcing steel supports are installed inside the arch-shaped formwork. The arch-shaped formwork is then installed on a coupler-type steel pipe. Concrete is poured into the arch-shaped formwork, and the triangular area between the arch-shaped formwork and the frame beams and columns is filled to connect the entire arch. This achieves an arch-shaped appearance on the building surface. Furthermore, the arch-shaped formwork can be made in any size to adapt to any construction structure. Finally, the walls and exterior walls are plastered to achieve an aesthetically pleasing finish.

[0037] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
