Problems solved by technology

[0003] However, the current aluminum alloy formwork usually does not have a support structure for strengthening the aluminum alloy formwork. When the aluminum alloy formwork is used, there are also some problems: because the aluminum alloy formwork is light in weight, the concrete has fluidity when pouring concrete. The stress on the stair formwork is uneven, and the stair formwork is easy to move due to unstable positioning, resulting in the size of the poured wall surface inconsistent with the designed size, requiring reprocessing of the wall surface at the place where the concrete is poured, increasing construction time and cost
[0006] However, in actual construction projects, due to the vibration during concrete pouring, the pins or wedges are likely to fall off, which will cause the beam or the adjacent area of ​​the support head of the flat form to slide down and slide, and the wall formwork, column formwork, beam formwork and their supports will also be affected. It is prone to displacement; in order to be able to observe the overall situation of the aluminum alloy formwork system in real time; multiple operators are required to be on both sides of the wall being poured at any time to check the connection of each pin, wedge and pull screw; more is required manpower, the cost of manpower is relatively high

Embodiment 1

[0049] An aluminum alloy formwork system, including multiple installation formworks and connectors, adjacent installation templates and opposite installation templates are connected by connectors, and 0.5-2cm of adhesive is applied to the connection between the connectors and the installation templates. The main component of the binder is clay. Adhesive is also applied to the joints of adjacent mounting templates.

[0050] The further installation formwork is covered with a 0.3-0.6 cm thick film on the concrete side. The film can be selected from polyethylene film, polypropylene film, polyvinyl chloride film or polyester film. The film extends from the ground along the installation direction of the installation template, the surface area of ​​each film is greater than 4 times the surface area of ​​each installation template, and the films attached to the opposite installation templates are arranged in parallel.

[0051] like figure 1 As shown, the installation template incl...

Embodiment 2

[0068] 1. Construction preparation

[0069] (1) Technical preparation

[0070] 1. According to the project structure form and contract duration requirements, design the construction site of the tower, write the operation process requirements and precautions.

[0071] 2. Template material preparation: prepare materials according to the template design drawing.

[0072] 3. According to the template design requirements, make safety and technical disclosure to the team.

[0073] 4. Measurement and setting out: after the concrete pouring of the floor is completed, the main control line is projected, all the column side lines are released on the floor, and the floor elevation line is measured on the diagonal line of the column reinforcement or on the steel pipe pole; before the formwork is installed , must review the elevation of the floor and the main control axis. The pole uses an adjustable pole, and the adjustment part is in the middle of the pole, which is easy to operate an...

Embodiment 3

[0178] The construction method of the aluminum alloy formwork system, the difference between embodiment 3 and embodiment 2 is that a number of ventilation pipes are inserted into the cavity formed by the installation formwork, and ventilation holes are evenly opened on the ventilation pipes. The ventilation pipe can be pre-buried on the ground in advance, and the ventilation holes are uniformly covered with the entire ventilation pipe, which is convenient for ventilation and is beneficial to increase the contact area between the concrete and the ventilation pipe; the material of the ventilation pipe is stainless steel.

Abstract

The invention relates to the technical field of building construction, in particular to an aluminum alloy formwork system and a construction method thereof. It includes a plurality of installation templates and connectors, adjacent installation templates and opposite installation templates are connected through the connectors, the joints of the connectors and the installation templates are coated with adhesive, and the main component of the adhesive is clay. The adhesive has a good bonding effect and can strengthen the connection between the connecting piece and the installation formwork. It is difficult for the connecting piece to fall off during the pouring of concrete, so there is no need for multiple operators to be on call at any time, which greatly saves labor costs. The dislocation of the installation formwork is not easy to occur, and the concrete surface after pouring is also smoother. Clay is a fine-grained rock ore, and the clay has good adhesion when exposed to water, which is convenient for coating. The clay will slowly dry in the air, and the dried clay will form a hard rock-like block, which further strengthens the structure of the installation formwork strength.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an aluminum alloy formwork system and a construction method thereof. Background technique [0002] Aluminum alloy formwork for construction is a new generation of formwork system after wood formwork and steel formwork. The aluminum alloy template is extruded by special equipment. It is composed of three parts of the aluminum panel, the bracket and the connecting piece. The system formwork of assembly and industrialized construction solves the defects of traditional formwork in the past and greatly improves the construction efficiency. The use of aluminum alloy formwork system is easy to disassemble and assemble, the construction period is short; the number of repeated uses is low, and the average cost of use is low; low carbon emission reduction, so it is very popular among construction workers and has also been rapidly promoted. [0003] However, the current alum...
