Embodiment 1

[0025] like Figure 1 to Figure 3 As shown, according to a construction column formwork according to a specific embodiment of the present invention, the formwork is surrounded by a plurality of concrete slabs 1 and forms a cavity. The cavity is "one", "L", "T" and so on. The junction of the concrete slabs 1 is at an angle of 90°. A plurality of concrete slabs are set on the same horizontal plane and are integrally formed. There is an opening on one side of the formwork. The concrete slab is made of multi-layer steel bars 2 and poured concrete. The formwork of " one " font is example, and present embodiment has 2 layers of steel bars. The steel bar adopts Φ5mm steel bar. The thickness of the formwork is 15-20mm, and the formwork is relatively light and thin. After construction, the formwork and the structural column can be better combined into a whole, and the work intensity of the constructor can also be reduced.

Embodiment 2

[0034] The difference between this embodiment and embodiment 1 is that the raw materials of the concrete are different. In parts by weight, the raw materials of the concrete include: 50 parts of stone powder, 10 parts of cement, 3 parts of carboxyethyl cellulose, 3 parts of acrylic acid, 3 parts of maleic anhydride, 2 parts of water reducer, 3 parts of salicylic acid , 3 parts of hydroquinone, 4 parts of boric acid and 2 parts of dispersible latex. The water reducer is YZ-1 naphthalene series high-efficiency water reducer.

[0035] In parts by weight, the redispersible latex is mainly made of the following raw materials: 30 parts of EVA rubber powder, 15 parts of azodicarbonamide, 2 parts of sodium oleate, 3 parts of peanut oil and 1 part of anti-caking agent. The anti-caking agent is talcum powder.

Embodiment 3

[0037] The difference between this embodiment and embodiment 1 is that the raw materials of the concrete are different. In parts by weight, the raw materials of the concrete include: 100 parts of stone powder, 20 parts of cement, 1 part of carboxyethyl cellulose, 7 parts of acrylic acid, 1 part of maleic anhydride, 7 parts of water reducing agent, and 1 part of salicylic acid , 9 parts of hydroquinone, 1 part of boric acid and 7 parts of dispersible latex. The water reducer is sodium lignosulfonate.

[0038] In parts by weight, the redispersible latex is mainly made of the following raw materials: 50 parts of EVA rubber powder, 6 parts of azodicarbonamide, 6 parts of sodium oleate, 0.5 part of peanut oil and 3 parts of anti-caking agent. The anti-caking agent is kaolin.

Abstract

The invention discloses a structural column mold shell which is formed and enclosed by a plurality of concrete slabs and forms a cavity. The plurality of concrete slabs are arranged on the same horizontal surface and are formed integrally. One side of the mold shell is provided with an opening, the concrete slab is made of layers of steel bars and concrete, and the layers of the steel bars are horizontally distributed from top to bottom inside the slab. The raw material formula of the concrete of the structural column mold shell is reasonable, and layers of steel bars are placed in the mold shell to improve the mechanical properties of the mold shell as a whole. The mold shell is simply installed on the structural column during the construction, then pouring is carried out, and no demolition is needed in later stage, thereby avoiding the safety hazard caused by the removal of the formwork and reducing the workload of the workers. The mold shell is light and thin, the thickness of the mold shell is 15-20 mm, the mold shell and the structural column can be better combined into one whole after the construction, and the work intensity of the constructors can be reduced. The preparationmethod of the structural column mold shell is simple, and is easy to implement and master.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a construction column formwork and a preparation method thereof. Background technique [0002] The number of construction projects in our country is constantly increasing. This is mainly to provide residents with a more comfortable living environment. In the case of construction, wood formwork is one of the necessary accessories, which mainly plays a role in the construction of buildings. to a certain fixation. At present, domestic building walls can be roughly divided into two types: one is to build the frame first and then fill the wall, and reserve structural columns in the wall; the second is to reserve structural columns while building the wall, no matter which one They are all inseparable from the wall structure column. The conventional method is to reserve an irregular gap when building the wall, insert the tied steel cage into the gap, clamp two or more sides with wood...
