A convex rib is provided at the top of the block body, and a groove is provided at the bottom thereof. When two block bodies are stacked, the convex rib matches the groove; three vertical through holes are opened in the block body, and the middle one of the through holes is a grouting hole; during construction, the block bodies are connected left and right and staggered by half a brick up and down, and after single-row construction and grouting, they are used for the infilled wall of the masonry structure.

[0003] However, it uses wet construction of pouring cement for integration, resulting in it being very difficult to separate the blocks from each other and the blocks from the steel bars without damage, so that recycling cannot be achieved. Summary of the Invention

[0004] The purpose of the present invention is to provide a construction method for an easily disassembled and assembled block infilled wall structure and an infilled wall to solve the problem that the existing mortise and tenon hollow blocks cannot be disassembled and assembled after construction. To achieve the above purpose, the present invention is solved by the following technical solutions:

[0005] In a first aspect, the present invention provides a construction method for an easily disassembled and assembled block infilled wall structure, including:

[0006] Install a T-shaped support structure on the bottom structure floor slab. A number of bottom blocks are arranged on both sides of its web, and two by two are connected into a whole through bolts passing through the web and form a mortise groove at the top;

[0007] Stack and mortise the middle blocks to a set height. The bottom layer is mortised with the bottom blocks, and a mortise groove is reserved at the top layer; construct the top blocks on the top structure floor slab, with the same construction method as the bottom blocks. The mortise groove formed by the top blocks is mortised with the mortise groove reserved at the top layer of the middle blocks through a mortise tongue.

[0008] As a further technical solution, the middle blocks stagger and overlap with each other and with the top and bottom blocks up and down.

[0009] As a further technical solution, the middle blocks use standard blocks with two mortise joint structures and half blocks with one mortise joint structure alternately.

[0010] As a further technical solution, a number of keels are respectively provided on both sides of the blocks between the bottom structure and the top structure, and the corresponding keels on both sides are connected together through bolts passing through the blocks.

[0011] In a second aspect, the present invention provides a demountable block infilled wall constructed by using the construction method of the demountable block infilled wall structure described in the first aspect, including:

[0012] A bottom structure, including a bottom floor slab, a first T-shaped support structure, and a number of bottom blocks. The first T-shaped support structure is fixed on the bottom floor slab of the structure. The bottom blocks are arranged on both sides of the web of the first T-shaped support structure and are connected by bolts.

[0013] A middle structure, whose bottom is tenoned to the bottom structure, including a number of middle blocks tenoned in layers.

[0046] Next, the technical solutions in the typical embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0047] As Figures 1 - 20 shown, this embodiment provides an easy-to-disassemble and assemble block infilled wall structure construction method and an infilled wall constructed by using this method.

[0048] (1) Construct the bottom structure.

[0049] 1. Install the bottom keel structure.

[0050] As Figure 1 、 Figure 2 and Figure 15 shown, in this embodiment, the first T-shaped support structure is composed of two L-shaped keels 2, mainly for the convenience of production and also for the general-purpose recycling after disassembly. It can be understood that in some other embodiments, T-shaped keels can also be directly adopted. The side plates of the two L-shaped keels 2 form the flange part of the first T-shaped support structure, and the other two side plates form the web part. Expansion bolt holes 22 are opened in the flange part, and the L-shaped keel 2 is fixed on the bottom structure floor slab 1 by using expansion bolts. In order to absorb errors, the first bolt holes 21 on the keel are all designed as long holes.

[0051] 2. Install the bottom blocks.

[0052] As Figure 16 shown, the top of the bottom block 3 (from the view angle) has a bottom block mortise groove 31 (half of the mortise groove structure). After two bottom blocks 3 are butted, a complete mortise groove is formed. In this embodiment, the mortise groove is a tapered hole groove with a smaller diameter at the bottom and a larger diameter at the top. The bottom and the butting surface are flat, and a rectangular protrusion is provided on the opposite surface of the butting surface to facilitate the formation of a vertical through groove through the C-shaped keel in the later stage. In addition, a second bolt hole 32 penetrating the block is provided on the butting surface.

[0053] The purpose of installing the bottom block 3 is to construct a fixed mortise and tenon groove to lay the foundation for the placement of the upper blocks.

[0054] As Figure 3 and Figure 4 shown, when installing the bottom block 3, several are respectively placed on both sides of the keel web according to actual requirements, and two form a standard block. The first bolt 4 passes through the second bolt holes 32 of the two bottom blocks 3 and the first bolt holes 21 of the L-shaped keel 2, and the two bottom blocks 3 are installed on the L-shaped keel 2 and butted at the top to form a complete mortise groove. All other bottom blocks 3 are installed in this way, and the bottom structure forms an integral structure.

[0055] (2) Construct the middle structure, the bottom of which is tenoned with the bottom structure and includes several stacked and tenoned middle blocks.

[0056] 1. Install the middle blocks.

[0057] As Figure 17 shown, in this embodiment, the middle block 5 is divided into two types of blocks, a standard block 51 and a half block 52. Among them, the standard block has two tenoning structures, that is, two groups of oppositely arranged mortise grooves 55 and tenon tongues 56, and the half block only has one group of oppositely arranged mortise grooves 55 and tenon tongues 56. The mortise grooves 55 and tenon tongues 56 of the middle block 5 and the bottom block mortise groove 31 are all mutually adapted and the tenoning is completed by up and down insertion.

[0058] The tenon tongue of the building block is an inverted cone with a larger upper part and a smaller lower part, which exactly fits with the mortise groove. To ensure tight insertion and avoid installation errors caused by production errors, the mortise groove is about 1 cm deeper than the tenon tongue.

[0059] As Figure 5 and Figure 6 shown, the middle building blocks 5 are stacked and tenon-connected to the set height. The middle building block 5 at the bottom layer is tenon-connected to the bottom building block 3, and a mortise groove 55 is reserved for the middle building block 5 at the top layer, that is, the mortise groove of the middle building block 5 at the top layer faces upward after the masonry is completed.

[0060] The middle building blocks 5 themselves and the upper and lower ones with the top building block 10 and the bottom building block 3 all adopt the staggered joint method. Standard blocks 51 and half blocks 52 are alternately used in the same layer to ensure the overall stability.

[0061] In addition, as Figure 18 shown, the half block 52 of the middle building block 5 is axisymmetric with respect to two axes with the top view plane as the reference and the axes of symmetry are perpendicular. Furthermore, the standard block 51 formed by the half block 51 is also axisymmetric with respect to two axes. Based on this, the masonry of the corner can be completed, as Figure 7 shown.

[0062] 2. Install the tenon tongue pin.

[0063] As Figure 19 shown, the tenon tongue pin 6 has two tenon tongues arranged oppositely, which are adapted to the mortise grooves of the middle building block 5 and the top building block 10.

[0064] As Figure 8 and Figure 9 shown, first insert the tenon tongue pin 6 into the mortise groove of the top building block 10, and the upper tenon tongue of the pin is exposed.

[0065] (3) Build the top structure, which is tenon-connected to the top of the middle structure through the tenon tongue pin 6.

[0066] 1. Install the top keel structure.

[0067] As Figure 8 and Figure 9 shown, the second T-shaped support structure is installed on the top structure floor slab 7. Its structure is the same as that of the first T-shaped support structure, and both are composed of two L-shaped keels 2. The specific structure and construction method are the same as those of the bottom keel structure and will not be elaborated here.

[0068] 2. Install the top building block.

[0069] As Figure 10 and Figure 11As shown, the structures of the top block 10 and the bottom block 3 are the same. The difference is that after installation, one mortise and tenon groove faces downward and the other faces upward. The installation method of the top block 10 and the L-shaped keel 2 is also the same as the connection method between the bottom block and the L-shaped keel 2, which will not be elaborated here in detail.

[0070] In addition, it should be noted that when the bottom block 3 and the top block 10 are butted to form a standard block, a mounting gap for the L-shaped keel 2 needs to be reserved in the middle. The specific size of the gap is determined according to the thickness of the L-shaped keel. Moreover, the horizontal positions of the bolt holes on the bottom block 3 and the top block 10 are both lower than the mortise and tenon grooves, and the outer screw holes are countersunk to facilitate the direct and tight fitting installation of the external rigid decorative plates in the later stage.

[0071] 3. Tenon joint with the tongue pin.

[0072] As Figure 10 and Figure 11 shown, the constructed top structure is tenon-jointed with the tongue of the tongue pin 6 through the mortise and tenon groove of the top block 10, so as to ensure the stability of the fixed top structure.

[0073] (IV) Install the C-shaped keel.

[0074] A number of keels are respectively provided on both sides of the blocks between the bottom structure and the top structure, and the corresponding keels on both sides are connected together by bolts passing through the blocks.

[0075] Specifically, as Figure 20 shown, in this embodiment, the keel is a C-shaped keel 8, and the C-shaped keel 8 is provided with a fourth bolt hole 81, which is similar to the first bolt hole 21.

[0076] Vertical grooves 53 and third bolt holes 54 are reserved on the middle block 5, and the vertical grooves 53 of the adjacent middle blocks above and below can form a vertical through groove.

[0077] As Figure 12 and Figure 13 shown, the C-shaped keel 8 is installed in the vertical through groove formed by the blocks, and the two C-shaped keels 8 are fixed with the second bolt 9. Fixing points are interspersed in the upper and lower L-shaped keels and the middle wall, so as to ensure the stability of the C-shaped keel 8. In this way, on the one hand, the stability of the wall against horizontal displacement is enhanced, and at the same time, the stability against vertical plane bending is strengthened. And the use of the C-shaped cross-section keel is also intended to enhance the bending stiffness of the keel itself.

[0078] After installing the C-shaped keel 8, a filler wall is formed, as Figure 14 shown.

[0079] Although the present invention has been disclosed above in preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make possible changes and modifications to the technical solution of the present invention by using the methods and technical content disclosed above without departing from the spirit and scope of the present invention. Therefore, any simple modifications, equivalent changes and decorations made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention shall fall within the protection scope of the technical solution of the present invention.
