Technical Field

The utility model belongs to the technical field of assembled building walls, and in particular relates to an assembled building energy-saving wall.

Background Art

Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, process and manufacture building components and accessories in factories, transport them to construction sites, and assemble and install them on site through reliable connection methods. Prefabricated walls are widely used, and the walls of existing prefabricated buildings are usually composed of decorative panels on both sides of reinforced concrete. For example, the Chinese utility model patent with application number 202121700132.7 discloses an energy-saving and heat-insulating wall of a prefabricated building, including a positioning plug embedded in the wall and a soft layer attached to the wall, and the outer surface of the soft layer is attached with a sound insulation board, a heat insulation board and a decorative panel in sequence, wherein the soft layer and the sound insulation board, and the heat insulation board and the decorative panel are all fixed by gluing, and the sound insulation board and the heat insulation board are fixed by screwing, and the positioning plug is located at one end of the wall body. A mounting groove is opened, and a U-shaped connector is inserted into the interior of the mounting groove. The opening of the connector faces outward, and both sides of the connector protrude outward to form a card block, and both sides of the inner wall of the mounting groove are provided with a card slot that matches the card block. The utility model fixes the soft layer and the sound insulation board on the outer wall of the wall through structures such as positioning plugs and connectors, and the thermal insulation board is screwed and fixed on the outer wall of the sound insulation board. Therefore, the utility model is easy to dismantle and will not cause great damage to the wall.

However, the above-mentioned prior art requires the use of mortar and connectors to fix the insulation board on the concrete wall, which is complicated to install and has weak insulation performance. In cold weather, the heat dissipates quickly, thus affecting the comfort inside the prefabricated building. In addition, the existing prefabricated buildings are usually ventilated by opening windows, and the ventilation efficiency is low. It is difficult to update the air inside the prefabricated building, thus affecting the comfort of residents. Based on this, it is urgent to design a hollow exterior wall insulation wall, and cooperate with the inner and outer formworks to realize the pouring of the concrete wall and complete the installation of the external insulation structure at the same time.

Embodiment 1:

Referring to Figures 1, 2 and 3, an assembled building energy-saving wall includes a concrete wall 1, an insulation layer 2, an anti-cracking protective layer 3, a finishing layer 4, and a connector 5 fixedly penetrated through the insulation layer 2 and the concrete wall 1.

The insulation layer 2 includes an insulation board with ventilation grooves 21 formed inside. The insulation board can adopt an integral structure, that is, the ventilation grooves 21 are formed in the middle of the entire insulation board. However, after the ventilation grooves 21 are formed, the overall structural strength of the insulation board and the connection strength of the concrete wall 1 are affected. Therefore, in this embodiment, the insulation board is designed as a split structure and a reinforcement structure is provided therein, that is, the insulation board includes a first insulation board 22 and a second insulation board 23. A plurality of ventilation grooves 21 are vertically formed on the end face of one side of the first insulation board 22 facing away from the concrete wall 1. Thus, connecting protrusions 24 are formed on both sides of the ventilation grooves 21. A reinforcement board 25 is bonded to the end face of one side of the first insulation board 22 with the ventilation grooves 21, and the second insulation board 23 is bonded to the outer end face of the reinforcement board 25.

In this embodiment, in order to improve the structural strength of the thermal insulation layer 2 and the connection strength with the concrete wall 1, the reinforcing plate 25 is a reciprocating bending structure and one end surface of the reinforcing plate 25 is respectively bonded to the bottom of the ventilation slot 21 and the outer end surface of the first thermal insulation plate 22, that is, the reinforcing plate 25 covers the ventilation slot 21 and the connecting protrusion 24. The connecting member 5 is fixedly inserted into the second thermal insulation plate 23, the reinforcing plate 25, the first thermal insulation plate 22 and the concrete wall 1 in sequence, thereby improving the connection strength between the thermal insulation layer 2 and the concrete wall 1.

In this embodiment, the material used for the insulation board can be graphite polystyrene board, extruded board, XPS board, rock wool board and other materials, and graphite polystyrene board can be preferred, and the reinforcing board 25 can be made of plastic. The thickness and overall size of the first insulation board 22, the reinforcing board 25, and the second insulation board 23 can be specifically selected according to actual construction needs, and the bonding material between the first insulation board 22, the reinforcing board 25, and the second insulation board 23 can be an existing insulation board adhesive.

The connecting member 5 includes a fixed connecting member 51 and a ventilation connecting member 52. The fixed connecting member 51 is used to fix the second insulation board 23, the reinforcement board 25, and the first insulation board 22 to the concrete wall 1. In addition, in this embodiment, when pouring the concrete wall 1, a through-wall screw (used to fix the inner formwork on the inner side of the concrete wall 1 and the outer formwork on the outer side of the insulation layer) can also be inserted therein.

As shown in FIG6 , the fixed connector 51 is a hollow structure and includes a fixed limiting plate 511, a fixed sleeve 512 integrally formed on one end surface of the fixed limiting plate 511, a fixed annular groove 513 is provided at one end of the fixed sleeve 512 away from the fixed limiting plate 511, and a fixed hole 514 coaxial with the fixed sleeve 512 is provided on the fixed limiting plate 511. The length of the fixed sleeve 512 is based on the end thereof reaching the inside of the concrete wall 1. Preferably, since the through-wall screw needs to be inserted into the fixing hole 514 and the fixed sleeve 512 when the concrete wall 1 is cast in situ, and the through-wall screw needs to be removed after the concrete wall 1 is cast, for this reason, the end of the fixed sleeve 512 away from the fixed limiting plate 511 can be flush with the inner end surface of the concrete wall 1. By setting the fixed annular groove 513, firstly, concrete can be poured into the fixed annular groove 513, thereby improving the connection strength between the insulation layer and the concrete wall 1; secondly, the outer circumference of the fixed sleeve 512 can abut against the inner wall of the connecting through hole opened on the insulation board, thereby improving the connection strength between the fixed connector 51 and the insulation board.

As shown in FIG. 7 , the ventilation connector 52 includes a ventilation limit plate 521, a ventilation sleeve 522 integrally formed on one end surface of the ventilation limit plate 521, a ventilation hole 523 is provided at one end of the ventilation sleeve 522 close to the ventilation limit plate 521, and the ventilation hole 523 is connected to the inner cavity of the ventilation sleeve 522 and the ventilation slot 21 of the insulation board respectively, and a fastening ring groove 524 is provided at one end of the ventilation sleeve 522 away from the ventilation limit plate 521. The ventilation connector 52 and the fixed connector 51 have the same principle of connecting the insulation layer 2 and the concrete wall 1, and the difference is that: since the ventilation connector 52 does not need to be penetrated by a through-wall screw, the ventilation limit plate 521 does not have a corresponding through hole, that is, it is a closed structure.

As shown in Figure 3, in order to ensure that when a connecting through hole is opened on the second insulation board 23, the connecting through hole is aligned with the connecting protrusion 24 on the first insulation board 22 to avoid drilling into the ventilation groove 21 on the first insulation board 22, a convex plate 26 corresponding to the ventilation groove 21 is integrally formed on the outer end face of the second insulation board 22, that is, a ventilation connector 52 is fixed on the convex plate 26, and a fixed connector 51 is installed on the second insulation board 23 outside the convex plate 26.

As shown in Figs. 4 and 5, further, in order to reduce the number of ventilation connectors 52 and improve the ventilation efficiency of the entire insulation layer 2, the ventilation slots 21 are interconnected, ventilation notches 27 can be provided at the upper and lower parts of the connection protrusions 24, and reinforcement plate notches 251 can be provided on the reinforcement plate 25. Thus, only one ventilation connector 52 for air intake and one ventilation connector 52 for air discharge are needed to realize the circulation ventilation in the insulation layer 2.

Furthermore, the anti-crack protective layer 3 includes a first anti-crack mortar layer 31, an alkali-resistant glass fiber mesh cloth 32, and a second anti-crack mortar layer 33, which are stacked in sequence, and the finishing layer 4 includes a flexible water-resistant putty layer 41 and a coating layer 42, which are stacked in sequence. The specific components and construction methods of the anti-crack protective layer 3 and the finishing layer 4 are prior art and will not be repeated here.

Embodiment 2:

As shown in Figure 3, the difference between this embodiment and embodiment 1 is that, for the convenience of processing and installation, the reinforcing plate 25 in this embodiment is a flat plate structure, and thus, there is no need to open a reinforcing plate notch, and it is only necessary to bond the two side end faces of the reinforcing plate 25 to the connecting protrusion 24 and the second insulation board 23 respectively.

The working process of the embodiment of the utility model is as follows:

1. The first insulation board 22, the reinforcing board 25 and the second insulation board 23 of the utility model are sequentially bonded to form an insulation layer 2 for standby use;

2. Install the steel truss of the concrete wall 1, and fix the inner layer formwork inside the steel truss, fix the insulation layer 2 of step 1 on the other side of the steel truss, and install the fixed connector 51 and the ventilation connector 52 respectively, install the outer formwork outside the insulation layer 2, and insert the through-wall screw in the outer formwork, the fixing sleeve 512 of the fixing connector 51 and the inner formwork in sequence and fix the through-wall screw. In order to facilitate the insertion of the through-wall screw in the fixing sleeve 512, the inner formwork and the outer formwork can use the existing frame formwork structure;

3. Cast the concrete wall 1. When the strength of the concrete wall 1 is not less than 1MPa, remove the inner and outer formworks and the through-wall screws;

4. The anti-cracking protective layer and the finishing layer are sequentially constructed on the second insulation board 23 ; ventilation equipment can be installed on the inner side of the concrete wall 1 and connected to the ventilation sleeve 522 of the ventilation connector 52 .

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
