Abstract

The invention discloses a heat-preserving cast-in-situ stripe for a novel sintered shale heat-preserving hollow building block wall body. The heat-preserving cast-in-situ stripe comprises novel sintered shale heat-preserving hollow building blocks built on the cast-in-situ stripe of a main wall body, wherein the main wall body is partitioned into an upper wall body and a lower wall body; a layer of novel sintered shale heat-preserving hollow building blocks is built on the inner and outer sides of the upper section of the lower wall body along the width direction respectively; full-length tension meshes are arranged between the two layers of novel sintered shale heat-preserving hollow building blocks; the two ends of two longitudinal ribs in the full-length tension meshes are reliably connected with construction columns respectively; and transverse tension ribs are arranged between the two layers of novel sintered shale heat-preserving hollow building blocks along the length direction of the main wall body at certain intervals. According to the cast-in-situ stripe, a heat bridge effect between the cast-in-situ stripe and the novel sintered shale heat-preserving hollow building block wall body is avoided effectively on the premise of ensuring the high efficiency and convenience of construction, and the average heat transfer coefficient of a wall body is increased, so that the heat preserving and heat insulating properties of the wall body are improved; and meanwhile, shrinkage fractures can be reduced effectively, the job progress can be accelerated effectively, and continuous construction is realized.

Description

technical field

[0001] The invention belongs to the technical field of building structures, and in particular relates to a heat-preservation cast-in-place tape for walls, in particular to a heat-preservation cast-in-place tape for sintered shale heat-preservation hollow block walls, which is used for external walls. Background technique

[0002] The walls of the building are used to separate and maintain indoor and outdoor spaces, and at the same time have a load-bearing function, and the outer walls should also have good thermal insulation performance. At present, the total energy consumption of buildings in my country accounts for nearly 1 / 3 of the total energy consumption of the society, and about 80% of the heat consumption of buildings is mainly transmitted in or out through the heat transfer of the envelope structure, of which the external walls account for 23-24%. Therefore, reducing the energy consumption of buildings, especially the heat dissipation energy consumpti...

Embodiment

[0026] In order to illustrate the performance of the cast-in-place tape of the present invention, the inventor built a new type of sintered shale heat-insulating hollow block wall with the heat-preservation cast-in-place tape of the present invention, and built an ordinary new type of sintered shale heat-preservation hollow block wall block wall, and conducted a thermal performance test study. The specific process is as follows:

[0027] During the construction, the main wall 1 is built with whole bricks, the wall thickness is 365mm, and the construction method is the sticky mortar method. At the cast-in-place belt part of the main wall 1, after cleaning the section of the lower wall, stick the special mortar with the new sintered shale insulation hollow block 2. Hollow blocks 2 are placed on the inside and outside sides of the upper section of the lower wall, so that the long sides and large faces of the new sintered shale thermal insulation hollow block blocks 2 are flush w...
