[0035] Preferably, the first grooves and the second grooves are arranged in a staggered manner.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. Since the wall is formed by splicing wall panels and the wall is installed in the ground groove of the foundation body, on the one hand, the connection strength between the wall and the foundation body is increased, making them connected as one; on the other hand, it completely changes the traditional construction process and speeds up the construction progress; and due to the use of lightweight core blocks, the overall weight of the wall panel is reduced while the thermal insulation performance is improved.

[0038] 2. Before the wall panels are installed, a retaining frame is set above the base body, and the upper part of the wall is placed on the retaining frame to assist in completing the accurate connection of the wall panels, which saves time and effort and facilitates construction operations.

[0039] 3. Since the two parallel walls in the wall are tied and fixed, it is convenient to maintain the accurate position of each wall, so that each wall panel is tightly connected to prevent cavity leakage.

[0040] 4. Since the inner wall of the groove cavity of the wall panel is provided with a raised rib, on the one hand, it can enhance the strength of the inner wall of the groove cavity, and on the other hand, a protrusion is formed on the slurry filled during construction, which increases the strength of the slurry block while increasing the contact area between the slurry block and increasing the connection strength between the two.

[0041] 5. Since a support block is provided in the groove cavity, it can be filled between the first protective layer and the second protective layer to enhance its strength and avoid damage during transportation.

[0042] 6. Since a first groove is provided on the inner wall of the lightweight core block and a first protrusion is provided on the first protective layer, the first protrusion is installed in the first groove, so that the first protrusion plays the role of a reinforcing rib, thereby increasing the strength of the wall panel while reducing the weight of the wall panel; at the same time, the contact area between the lightweight core block and the first protective layer is increased, thereby increasing the bonding strength between the two.

[0043] 7. Since the first groove and the second groove are staggered, the first protective layer and the second protective layer can jointly increase the strength of the wall panel while maintaining the uniformity of the thickness of the lightweight core block as much as possible, which is conducive to maintaining the balance of thermal insulation of the wall panel and improving the overall thermal insulation effect of the wall panel.

[0044] 8. Since the first reinforcing net is provided in the first protective layer, the strength of the wall panel can be further increased.

[0045] 9. Since a connecting net is provided in the reinforcing rib, one end of the connecting net is connected to the first reinforcing net and the other end is connected to the second reinforcing net, so that the first reinforcing net and the second reinforcing net are connected as a whole, further increasing the overall strength of the wall panel.

[0046] 10. Since the ends of the first reinforcing net and the second reinforcing net extend into the groove cavity, when two adjacent wall panels are connected side by side, the first reinforcing net and the second reinforcing net are located in the enclosed cavity, and the reinforcing nets extending to the two wall panels are interwoven, which acts as a grid when pouring slurry, thereby increasing the overall stability of the wall.

[0047] 11. Since sealing grooves are provided on the side walls of the first protective layer and the second protective layer, sealing materials can be placed in the sealing grooves when the two wall panels are butt-jointed to prevent grouting materials from leaking from the gaps.

[0048] 12. The present invention can realize prefabricated construction, greatly shorten the construction period, subvert the traditional construction technology of village residential houses, and is easy to promote and apply in this field. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] In order to increase the sealing performance of two adjacent wall panels 3 when splicing, Figure 6 As shown, the side walls of the first protective layer 310 and the second protective layer 32 are both provided with sealing grooves 312. When connected, the sealing grooves 312 of the two adjacent wall panels 3 can be arranged relative to each other to form a large sealing groove 312, so that a sealing strip 311 can be placed in the large sealing groove 312 to prevent the slurry 13 from leaking when the slurry 13 is poured into the cavity surrounded by the two grooves.

The reinforcing rib 35, the first protective layer 310 and the second protective layer 32 together enclose a groove cavity located in the side wall of the wall panel 3, and a protruding rib 313 is provided on the inner wall of the groove cavity. The ends of the first reinforcing net 38 and the second reinforcing net 34 extend into the groove cavity.

[0069] The grooves of two adjacent wall panels 3 are connected to form a cavity, and the cavity is filled with adhesive slurry 13. The specific construction process is as follows:

[0070] S21: Setting the retaining frame 4: The retaining frame 4 is set above the basic body 1, and the retaining frame 4 is located at the corresponding position of the upper part of the wall panel 3; the retaining frame 4 can be installed on the wall of the two pairs of walls that have been installed, or can be installed on a bracket, and the bracket is relatively fixed on the basic body 1. The specific structural form of the retaining frame 4 can be selected from standard profiles with strength such as angle steel or channel steel.

[0071] S22 installing the sealing strip 311: installing the sealing strip 311 in the sealing groove 312 of the wall panel 3.

[0072] S23 Bending the reinforcing net: bending the ends of the first reinforcing net 38 and the second reinforcing net 34 to extend out of the groove cavity in an inclined shape.

[0073] S24 places the wall panel 3: the wall panel 3 after the operations of S22 and S23 is placed in the ground groove 2 of the foundation made by S1, the upper part of the wall panel 3 rests on the retaining frame 4, the groove cavities of two adjacent wall panels 3 are connected to form a wall, and the two groove cavities surround a cavity.

[0074] S25 installation corner guard: Figure 8 As shown, an outer corner protector 8 is installed on the outer wall of the corner of the wall body connected to S24, and an inner corner protector 7 is installed on the inner wall, and the inner corner protector 7 is fixedly connected to the outer corner protector 8. The specific fixing method can adopt the structure of a double-headed screw 6, that is, a connection hole is opened at the corresponding position of a straight arm of the inner corner protector 7 and the outer corner protector 8, and a connection hole is also opened at the corresponding position of the other straight arm, and then the double-headed screw 6 is equipped in the two corresponding connection holes, and nuts are installed to tighten and fix.

[0075] S26 Tie the wall: Tie and fix the two parallel walls in the wall connected by S24. The specific method is to place a railing on the outer wall of the front wall and another railing on the outer wall of the rear wall. The two railings are used in groups, and the two ends of the two railings are tied together correspondingly by using a steel wire rope or other rope belt 5 from the outside of the gables on both sides; the double-headed screws 6 on the same side wall of two adjacent outer corner guards 8 can also be connected by using a steel wire rope or other rope belt 5, and the double-headed screws 6 on the same side wall of two adjacent inner corner guards 7 can be connected by using a steel wire rope or other rope belt 5, so that the joints between the wall panels 3 in the wall are more tight.

[0076] S27 pouring slurry 13: after S26, the cavity is filled with adhesive slurry 13 to complete the wall construction. The slurry 13 can be mortar concrete or quick-setting and quick-drying slurry such as quick-drying powder slurry.

[0077] S3 pouring the ground trench 2: After the wall is constructed, the remaining space of the ground trench 2 is filled with adhesive slurry 13 to fill the ground trench 2.

[0078] S4 roof construction: fix the top plate to the upper end of the wall made in S2. The top plate can be made of color steel plates in the prior art, and the installation of specific color steel plates is already in the prior art; the wall panel 3 in this technology can also be used as the top plate, and the first protective layer 310 of the top plate at the position of the wall panel 3 is removed, and the first protective net and the second protective net of the wall panel 3 are inserted into the top plate, and then the slurry 13 is used for pouring and filling, and the first protective net and the second protective net are fixed in the top plate to achieve a fixed connection between the wall panel 3 and the top plate. Of course, purlins can also be installed on the two gable walls, and the top plate can be placed on the purlins. This is already a prior art and will not be described in detail.

[0079] In the above construction process, if two adjacent wall panels are uneven when connected, such as misalignment, they can be adjusted with the help of inner guard plates 9 and outer guard plates 10, that is, inner guard plates 9 are set at the connection of the first protective layer of the two adjacent wall panels, and outer guard plates 10 are set at the connection of the second protective layer. Then, the inner guard plates 9 and outer guard plates 10 are tied and fixed with screws, and the pulling force is used to gradually adjust the wall panels so that the inner and outer walls of the wall panels are tightly attached to the inner guard plates 9 and the outer guard plates 10 in turn, and the wall panels are leveled. If the two adjacent wall panels are relatively flat, there is no need to level the inner guard plates 9 and the outer guard plates 10. Only "U"-shaped buckle plates 11 need to be used for grouting, which is convenient for increasing the construction speed. Fig. 9 and Fig.10 As shown, the "U"-shaped gusset plate 11 used includes two side walls and a top wall connecting the two side walls together, and is "U"-shaped as a whole. A grouting hole 12 is opened on the top wall of the "U"-shaped gusset plate 11. When in use, the "U"-shaped gusset plate 11 is buckled on the top wall of the connection between the two wall panels, and the position of the grouting hole 12 corresponds to the cavity. The two wall panels are buckled by the bending part of the top wall of the "U"-shaped gusset plate 11, and then grout is injected into the cavity through the grouting hole 12. After the slurry solidifies, the "U"-shaped gusset plate 11 is removed and continued to be used in the construction of other parts.

[0080] It should be noted that the above-mentioned inner corner guard 7, outer corner guard 8, double-headed screw 6, inner guard plate 9, outer guard plate 10, rope 5 and retaining frame 4 are all auxiliary tools for easy installation, which will be removed after the slurry 13 is finally set and do not belong to the components of the house.

[0081] The first reinforcing net 38, the second reinforcing net 34 and the connecting net 36 can be made of a steel wire mesh or a stronger steel mesh, etc., as long as they can strengthen the effect, and no specific requirements are made on their materials. The first protective layer 310, the second protective layer 32 and the reinforcing ribs 35 are all cement mortar layers, which can play a protective role such as fire prevention and reinforcement. The lightweight core block 31 used is a polyurethane foam insulation block, which is lightweight and has a greater insulation effect. The support block 37 can also be a polyurethane foam insulation block.

[0082] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention still belongs to the protection scope of the technical solution of the present invention.
