Embodiment 1

[0103] The target building is a 120m 2 The single-storey farmhouse is 15m long, 8m wide, and the front eaves are 1.3m wide. There is a solid wall and a beam in the room. There is a doorway and two windows on the front wall of the house, and two small ventilation windows on the back wall. Before construction, the building foundation and ground ring beams have been completed and have met the requirements of the next construction. The wall thickness is 240mm, so concrete blocks with W=200mm are used.

[0104] 1. According to the design positions of doorways, windows and beams, use H-shaped concrete blocks 1, rectangular hollow concrete blocks 9, small H-shaped concrete blocks 5 and cement mortar 25. Image 6 , Figure 7 , Figure 8 The front wall, back wall, side walls on both sides of the masonry house, T-shaped wall and 90° corner wall. press Figure 13 ~ Figure 18 , Construction of the electrical control cabinet 30, power switch 41, and socket 44 designed on the wall. Specifi...

Embodiment 2

[0115] The construction building is a 360m 2 The foundation of the three-story building has been completed and has met the next construction requirements. The wall thickness of the first floor is 260mm, the second floor is 240mm, and the third floor is 220mm. Therefore, concrete blocks with W=240mm, W=220mm, and W=200mm are used in sequence.

[0116] 1. Set up column reinforcement 27 for pouring reinforced concrete columns on the foundation;

[0117] 2. Press Picture 9 , 11 , 12, use H-shaped concrete block 1, rectangular hollow concrete block 9, b-shaped concrete block 17, 匚-shaped concrete block 13 and cement mortar 25 to build the first floor wall of the building (including the word Front wall, back wall, side walls on both sides, T-shaped wall and 90° corner wall), specifically:

[0118] A font wall (such as Picture 9 Shown) The concrete block masonry of the bearing wall column cavities of the front wall, the back wall and the side walls on both sides, the left side of the fir...

Embodiment 3

[0132] Construction building is a 3000m 2 The foundation of the seven-story residential building has been completed and has reached the next construction requirements. The wall thickness of the first floor is 340mm, and the wall thickness of the seventh floor is reduced by 20mm every time the floor is raised. Therefore, the W value of the concrete blocks used on each floor is 20mm smaller than the wall thickness.

[0133] 1. Set up column reinforcement 27 for pouring reinforced concrete columns on the foundation.

[0134] 2. On the fourth and lower floors of the building, the straight front wall, back wall, and the load-bearing wall pillars on the side walls on both sides, such as Picture 10 As shown, on the first floor, an H-shaped concrete block 1 is built between the bearing wall column reinforcement 27, and then two rectangular hollow concrete blocks 9 are used to connect, or two square-shaped concrete blocks 13 sets Lay outside the load-bearing wall column reinforcement 27, a...

Abstract

The invention provides a foam concrete composite heat preservation wall body with concrete blocks, belonging to the field of building energy conservation. The foam concrete composite heat preservation wall body is used for buildings, such as dwellings, workshops, hotels and the like, and is particularly suitable for new rural reconstruction. The wall body provided by the invention is prepared by constructing different combinations of five concrete precast blocks with different shapes with cement mortar. According to a quantity of floors, the wall body is reinforced, and a wall post and a ring beam can be borne by using wall body reinforcing ribs with different quantities, different manners and different specifications. Ordinary concrete is cast at positions of posts and beams in the hollow wall body, and foam concrete with a concentration of 200-400 kg / m<3> is cast at the other positions, so as to form the heat preservation and sound insulation wall body, and carry out mortar plastering and decoration. When the wall body provided by the invention is more than or equal to 250 mm thick, an average volume weight of the wall body is less than or equal to 600 kg / m<3>, a heat conduction coefficient is less than or equal to 0.4 W / (m2.K), and a pressure-resistant strength of a wall surface is more than or equal to 20 MPa. The wall body provided by the invention has the advantages of convenience and rapidness of construction. Furthermore, the wall body is firm, durable, mild, environment-friendly and safe.

Description

Technical field [0001] The invention relates to the field of building walls, in particular to a lightweight, high-strength, low-heat transfer concrete block foam concrete composite thermal insulation wall and a construction method thereof. It is used in residential buildings, factories, hotels and other buildings, and is especially suitable for new buildings. Rural construction. Background technique [0002] Building energy efficiency is a very important aspect of achieving a low-carbon economy. Among them, external wall insulation is the key to building energy saving. The external wall insulation technologies that are being used or promoted in China are: ①External application of foamed plastic board, involving patent number: 51610017053.X; ②Use of foamed plastic board as exterior wall sandwich, involving patent number: 51710057059.4, 02113520.7, 51610025948.8, 51610028878.1; Special additives make polystyrene particles or glass microbeads, glass fiber and cement into a slurry ...
