The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

Example 1

As shown in Figure 1, an energy-saving assembly module (also referred to as a straight mold) for a straight-type building, the module of the present invention is improved on the structure of the traditional energy-saving assembly module, so that the process of self-built houses is more scientific, More environmentally friendly, easier to construct, and more stable in seismic performance. The module has excellent characteristics such as high strength, good thermal insulation, sound insulation, flame retardant, cold resistance, corrosion resistance, moisture resistance, simple and fast construction, etc.

Specifically, the energy-saving assembly module described in this embodiment is composed of an inner panel 10 and an outer panel 20 , and the inner panel 10 and the outer panel 20 are both straight-shaped and made of energy-saving assembly materials.

More specifically, the inner and outer side panels are composed of an inner panel 101 close to the concrete layer and an outer panel 102 away from the concrete layer. The inner and outer panels 102 are integrally formed. Four edges of the side panels are formed with grooves, and the height of the inner panel 101 is greater than the height of the outer panel 102 . The tongue and groove are formed by the staggered arrangement of the inner and outer plates 102, which changes the traditional energy-saving assembly module with three layers of inner and outer layers, reduces the thickness of the module, and then increases the thickness of the concrete wall and improves the firmness of the building structure. It also avoids many security risks.

In addition, in order to make the splicing of the modules in the vertical direction more stable, a number of first protrusions 104 are provided at the top of the inner panel 101 , and first concave grooves adapted to the shape and size of the first protrusions 104 are provided at the bottom. Slot 105. The shape of the first groove 105 may adopt any shape in the prior art, such as a rectangular groove, a dovetail groove, a stepped groove, and the like.

In order to improve the fireproof performance of the house, the outer surface of the outer panel 102 is provided with a reinforced shell 40, and the material of the reinforced shell 40 is a class A fireproof and thermal insulation material. As a preference of this embodiment, the outer surface of the outer panel 102 is coated with an adhesive layer 50 , and the reinforcing shell 40 is bonded to the outer surface of the outer panel 102 through the adhesive layer 50 . Of course, it can also be fixed on the surface of the outer panel 102 by other mechanical connection methods. Since the fire rating of the energy-saving assembled module is basically the B1 fire rating, it can meet the requirement of self-extinguishing from the fire, but once the fire source of the house is in a burning state, the fire will spread rapidly. The fire source will not be extinguished immediately, which poses a great threat to the property safety and personal safety of the residents. A reinforced shell 40 with a class A fire rating is arranged on the surface of the outer panel 102 to suppress the spread of the fire.

In order to connect the inner and outer side panels, a connecting bridge 30 for connecting the inner and outer side panels is provided between the inner and outer side panels, and a plurality of through holes 103 are opened on the inner and outer side panels.

As shown in FIG. 2 and FIG. 3 , the specific structure of the connecting bridge 30 is as follows: the connecting bridge 30 includes a rod body 302 , a claw portion 301 , and a clamping groove portion arranged at both ends of the rod body 302 and adapted to the claw portion 301 . 303. The claw portion 301 includes a cap body 3011 that matches the through hole 103 and at least two elastic arm-shaped claw claws 3012 axially arranged on the cap body 3011 ; The outer side of the head of the elastic arm-shaped claw 3012 is provided with a tapered slope, and all the elastic-arm-shaped claw 3012 have at least one elastic arm-shaped claw 3012. The outer side of the elastic arm is provided with There are barbs 3013 , and a second groove 3031 adapted to the shape of the barbs 3013 is provided on the inner wall of the snap groove portion 303 . After the clamping claw portion 301 is inserted into the clamping groove portion 303 , a certain distance is reserved between the cap body 3011 and the surface of the clamping groove portion 303 for clamping the reinforcement housing 40 .

In the specific assembly process, the through hole 103 is a stepped hole, which is a first stepped hole, a second stepped hole and a third stepped hole in sequence from outside to inside. The size of the first stepped hole matches the size of the cap body 3011. The size of the second stepped hole matches the size of the elastic arm-shaped jaw 3012 , and the size of the third stepped hole matches the size of the engaging groove 303 . Specifically, the sum of the depths of the first stepped hole and the second stepped hole To reinforce the thickness of the casing 40 . However, due to the limitation of the precision of the machining mold in the actual machining process, the depth of the second stepped hole may not reach the distance reserved between the cap body 3011 and the surface of the engaging groove portion 303 , the claw portion 301 and the engaging groove portion 303 After assembly, there will be gaps and shaking, which will cause the inner and outer panels to be weakly connected, causing potential safety hazards. Therefore, in order to avoid the occurrence of the above situation, as a preferred technical solution, a plurality of arcs are arranged on the opposite surface of the engaging groove portion 303 and the claw portion 301 to obtain the second protrusion 3014, and the shape of the second protrusion 3014 is an arc. Of course, protrusions of other shapes are also within the protection scope of the present invention. For example, the reserved distance between the cap body 3011 and the surface of the snap groove portion 303 is 6 mm, and the depth of the second stepped hole after processing is 5 mm. At this time, the thickness of the arc protrusion 3014 can be set to 1.5 mm. The protruding material is the same as that of the connecting bridge and the side plate, both of which are non-rigid materials. After being squeezed, it will deform, and at the same time, a reaction force will be generated to squeeze the reinforcement plate, so that the clamping groove portion 303 and the claw portion 301 are connected. The connection is stronger. The function of the second protrusion 3014 is to compensate for the problem that the connection between the clamping groove portion 303 and the clamping claw portion 301 is not tightly connected due to machining errors.

The rod body 302 is provided with a plurality of reinforcing bar fixing grooves 3021 at intervals along the length direction of the rod body 302 . The reinforcing bar fixing groove 3021 is arc-shaped.

As shown in FIGS. 1 and 2 , the claw portion 301 is installed in the through hole 103 . After the module is formed, first install the claw portion 301 in the through hole 103, and then transport the inner and outer plates 20 and the connecting bridge 30 to the construction site. During the construction process, insert the engaging grooves 303 at both ends of the connecting bridge 30 into the respective slots 303. Connected to the claw portion 301, the assembly of the module is completed, and the module and the connector are shipped and transported in bulk. However, in the formwork of the prior art, the inner and outer panels 20 and the connecting piece are made of the same material and are integrally formed, which requires integral transportation, which not only increases the transportation cost, but also easily causes damage to the module, which further increases the cost. The formwork of the present invention solves the above-mentioned technology. question.

Specifically, the material of the connecting bridge 30 is plastic, and the connecting bridge 30 of other materials can also be used for replacement, such as the connecting bridge 30 made of metal or wood material, which can also achieve corresponding functions. Compared with the existing connectors made of materials such as integrally formed energy-saving assembly or foamed polyurethane, it has a more excellent effect.

Specifically, the specific size of the energy-saving assembled module described in this embodiment is: the distance between the inner and outer side panels is 160 mm, that is, the thickness of the concrete wall reaches 160 mm. As a preference but not limitation, the thickness of the inner panel 101 is 20 mm, the thickness of the outer panel 102 is 12 mm, and the thickness of the reinforced outer shell is 8 mm. Compared with the prior art, the thickness of the concrete wall is increased by 30 mm, and the increase in the internal thickness reduces the cavity caused by the uncompacted vibration of the concrete, and further enhances the stability of the house structure. In addition, before the concrete wall is poured, the steel bars are bound internally. Taking a steel bar with a diameter of 12 mm as an example, the thickness of the wall with a thickness of 13 cm in the prior art is after the steel bars are bound, and the distance between the steel bars and the front and rear side plates is less than 6 cm. In the process of building the wall, if the distance is too small, there will still be a cavity even after the vibrator is vibrated, and the present invention increases the distance between the inner and outer side panels to 160mm, and increases the steel bar and the inner and outer panels. The distance between 20 greatly reduces the existence of cavities and improves the overall safety performance of the house. In addition, due to the difference between the expansion coefficients of the steel bar and the concrete, the distance between the steel bar and the side plate is too close, which will cause the steel bar to break open the concrete protective layer in the later stage, resulting in damage to the wall.

As a preference but not limitation, the bulk density of the module in this embodiment is 25-30 kg/m ³ , and the detailed dimensions are: length 775 mm, width 240 mm, and height 325 mm. The staggered distance between the inner plate 101 and the outer plate 102 is 25 mm, that is, the depth of the formed groove is 25 mm.

In order to further reduce the existence of cavities in the concrete wall, at least one observation hole 106 penetrating inside and outside for observing the condition of the concrete chamber is provided on the inner side panel 10 and the reinforced outer shell 40 . In order to prevent the concrete from flowing out, a transparent cover 107 is installed in the observation hole 106 . The structure of the transparent cover 107 is shown in FIG. 6 , including a cylindrical body 1071 and a ring 1072 disposed at the end of the cylindrical body 1071 and coaxially disposed with the cylindrical body 1071 . The cylinder 1071 is installed in the observation hole 106, and the ring 1072 is arranged on the inner surface of the inner side panel 10 to prevent the transparent cover 107 from falling off during the concrete pouring process.

The assembly process of this embodiment is:

During assembly, the inner plate 101 and the outer plate 102 form a tongue and groove to assemble other modules in four directions, up, down, left, and right, and the first grooves 105 and protrusions 104 at the top and bottom of the inner plate 101 are used to realize the adjacent up and down direction. The module is fastened and assembled to avoid slurry running during the concrete pouring process and ensure the concrete strength. After the module position is fixed, the clamping grooves 303 at both ends of the rod body 302 in the connecting bridge 30 are clamped with the claw parts 301 in the inner and outer plates 20 at the corresponding positions to realize the connection and fixation with the inner and outer plates 20, that is, the module is completed. assembly. The module is prefabricated in the factory as a whole, and then assembled on site, which can effectively reduce the difficulty of on-site construction, speed up the construction speed, and improve the overall quality of the building structure.
