Combined type heat preservation cavity module

Abstract

The invention provides a combined type heat preservation cavity module, which comprises an inner plate and an outer plate which are vertically arranged in parallel, wherein the inner plate and the outer plate are combined into a heat preservation cavity module through connection pieces; fixing part insertion slots are formed in the front and rear side surfaces of the inner plate and the outer plate; each connection piece comprises a connection plate and fixing clamping parts located at two ends of the connection plate; the fixing clamping parts are inserted into the fixing part insertion slotsin the relative inner sides of the inner plate and the outer plate; fixing parts are arranged at positions, which correspond to the fixing clamping pieces, in the fixing part insertion slots in the relative inner sides of the inner plate and the outer plate; bolts penetrate through the fixing parts, the inner / outer plate and the fixing clamping parts to fixedly connect the connection pieces withthe inner / outer plate. By the connection pieces and the fixing parts of different lengths and different types, combined installation of the inner and outer plates with different thicknesses and different heights can be realized.

Description

technical field [0001] The invention relates to a thermal insulation cavity module. Background technique [0002] At present, the country puts forward the development requirements of vigorously developing prefabricated buildings. EPS cavity modules are important materials for building energy-saving and thermal insulation walls. The insulation performance of houses built with EPS cavity modules is the most ideal. With the promotion of the market, it has become very popular. universal. Although there are many brands of EPS cavity modules on the market, the inner and outer wall panels of the modules are fixed and cannot be disassembled as a whole. Generally, the walls need to be poured layer by layer multiple times. Wall modules with different thicknesses need to open wall module molds with different thicknesses.

Problems solved by technology

Although there are many brands of EPS cavity modules on the market, the inner and outer wall panels of the module are fixed and cannot be disassembled as a whole. Generally, the wall needs to be poured layer by layer for multiple times.

Wall modules with different thicknesses need to open wall module molds with different thicknesses. Repeated investment costs such as mechanical equipment molds will naturally increase, and the internal and external wall modules are fixed cavity modules, and the space occupied by inventory and transportation will increase virtually. In order to reduce the cost, the cavity module can only penetrate the vertical steel bar and install it from top to bottom during the construction process. The vertical steel bar is generally about 3 meters long and requires two people to work together. If you want to save labor, you can only reduce the height of the vertical steel bar and need to connect 2 bars. Up to 3 times, this wastes materials and labor and also affects the overall strength of the wall. Another disadvantage is that the inner and outer wall panels of the cavity module are insulation layers, and the main structure of the load-bearing wall of the building is not connected with the inner and outer decorative layers. The most important thing is that the groove on the insulation layer is bonded and connected with the mortar decorative layer. If the decorative layer is too thick and heavy, it will be deformed. With the aging and deformation of the insulation layer, the loose decorative layer will crack and fall off, and the existing cavity EPS modules are not decorated. The decorative layer needs to be done after the main body of the house is completed, or the existing thermal insulation and decorative integrated board is glued. This kind of board is made of pasting and compounding the thermal insulation board and the decorative board. Both boards have poor bonding strength and service life. , When the decorative surface is dry-hanging stone, expansion bolts need to be installed, which will inevitably damage the load-bearing structure of the load-bearing wall. The construction process is cumbersome and complicated, and the construction period is long. With the increase in labor costs year by year, the construction cost is uncontrollable and other shortcomings.
