DETAILED DESCRIPTION
[0021] The present invention will now be described in further detail with reference to the accompanying drawings.
[0022] As attached Figure 2 , Attachment Figure 5 and attached Figure 6As shown, a mold for wall construction according to an embodiment of the present invention includes a prefabricated base plate 31, a first rectangular column formwork 32 and a second rectangular column formwork 33. The first rectangular column formwork 32 is installed on the upper end of the prefabricated base plate 31, and the upper end surface of the first rectangular column formwork 32 is an opening. The second rectangular column formwork 33 is detachably mounted on the side of any left or right side of the first rectangular column formwork 32. The upper end surface of the second rectangular column formwork 33 is an opening. The height of the second rectangular column formwork 33 is higher than that of the first rectangular column formwork 32, and the side lengths of the left and right sides of the second rectangular column formwork 33 are smaller than the side lengths of the left and right sides of the first rectangular column formwork 32. The bottom of the second rectangular column formwork 33 is provided with an opening which is the same height as and connected to the first rectangular column formwork 32.
[0023] The present invention can prefabricate structures such as concrete blocks constructed by the first rectangular column formwork 32 and the second rectangular column formwork 33, namely the prefabricated stack 3 hereinafter, by setting a prefabricated base plate 31, a first rectangular column formwork 32 and a second rectangular column formwork 33. The concrete block structure constructed by the second rectangular column formwork 33 can be respectively clamped in the gaps between the autoclaved aerated blocks 2 for masonry of the wall body located on the left and right sides and arranged in an offset manner. The concrete block structures constructed by the first rectangular column formwork 32 are stacked on each other to form a rectangular box mounting groove 7 recessed in the surface of the wall body constructed by the autoclaved aerated blocks 2. In this way, a concrete block structure for stably cooperating with the autoclaved aerated blocks 2 arranged in an offset manner to form a box mounting groove 7 that can be embedded in a box can be constructed by the mold. The concrete block structure prefabricated by the mold can effectively ensure the stability of the wall after masonry, etc., and solves the problem of poor use effect of the back wall of the existing embedded fire extinguishing box.
[0024] In this solution, casting can be performed through the upper opening of the first rectangular column formwork 32 and the upper opening of the second rectangular column formwork 33. Casting can be performed separately as needed, or a cover plate can be added as needed to perform casting simultaneously.
[0025] In this embodiment, the second rectangular column template 33 can be detachably mounted on the side of any left or right side of the first rectangular column template 32 by presetting a groove or other structure for the lower end of the second rectangular column template 33 to be inserted in the prefabricated bottom plate 31; or, the first rectangular column template 32 and the second rectangular column template 33 can be detachably connected and fixed directly by manual or rivet structures. In this embodiment, the first rectangular column template 32 can also be detachably mounted on the prefabricated bottom plate 31 by means of a groove or other structure for insertion, so as to facilitate demoulding of the prefabricated parts after prefabrication.

In this way, when building the wall, the concrete block constructed by the second rectangular column template 33 can be effectively clamped in the gap between the autoclaved aerated blocks 2 on the left and right sides and staggered stacked. At the same time, the side of the concrete block constructed by the first rectangular column template 32 can just fit the autoclaved aerated block 2 located below the concrete block constructed by the second rectangular column template 33, thereby ensuring the tightness and reliability of the structure.
[0029] In a further specific embodiment, the spacing between the left and right sides of the second rectangular column template 33 is consistent with the lateral spacing between the two adjacent upper and lower offset stacked autoclaved aerated blocks 2. In this way, the tightness and reliability of the second rectangular column template 33 set at the gap of the autoclaved aerated blocks 2 are guaranteed.
[0030] As attached Figure 3 As shown, a method for using a mold for wall construction according to an embodiment of the present invention comprises the following steps: The second rectangular column formwork 33 is detachably fitted on the side of either side of the first rectangular column formwork 32, to obtain a left prefabricated stack mold 301 with the second rectangular column formwork 33 on the left side and a right prefabricated stack mold 302 with the second rectangular column formwork 33 on the right side; before pouring, the left prefabricated stack mold 301 and the right prefabricated stack mold 302 are sprinkled with water or coated with a release agent, and then, special-shaped tie bars 34 consistent with their structures are placed in the left prefabricated stack mold 301 and the right prefabricated stack mold 302 respectively, and the first rectangular column formwork 32 and the second rectangular column formwork 33 are poured, and vibrated as the pouring proceeds; after 7 days of film curing, the second rectangular column formwork 33, or the first rectangular column formwork 32 and the second rectangular column formwork 33 are removed as a whole to obtain a prefabricated prefabricated stack 3.
[0031] In this way, the required prefabricated stack 3 can be conveniently prefabricated through the above-mentioned mold, and the prefabricated prefabricated stack 3 structure can be reinforced by the special-shaped tie bars 34; when pouring, the deviation of the special-shaped tie bars 34 is within the allowable range.
[0032] As attached Figure 4As shown, a prefabricated stack prefabricated by a method for using a mold for wall construction according to an embodiment of the present invention, wherein the special-shaped tie bars 34 located inside the prefabricated stack 3 include: special-shaped steel bars 341 and connecting steel bars 342, the special-shaped steel bars 341 include a first special-shaped steel bar 4311 and a second special-shaped steel bar 3412, the first special-shaped steel bar 4311 and the second special-shaped steel bar 3412 are both "L"-shaped, one end of the first special-shaped steel bar 4311 is connected to one end of the second special-shaped steel bar 3412, and the plane where the first special-shaped steel bar 4311 is located is perpendicular to the plane where the second special-shaped steel bar 3412 is located, and the second special-shaped steel bar 3412 is located. The end of 412 that is not connected to the first special-shaped steel bar 4311 is set in a direction away from the first special-shaped steel bar 4311; the first special-shaped steel bar 4311 is used to be set in the first rectangular column template 32, and penetrates into the second rectangular column template 33 to be connected with the second special-shaped steel bar 3412 located in the second rectangular column template 33; several special-shaped steel bars 341 of different sizes are connected by several connecting steel bars 342 for connecting several special-shaped steel bars 341, and the structure matching the left prefabricated stack mold 301 and the right prefabricated stack mold 302 can be constructed respectively by setting the direction of the first special-shaped steel bar 4311, etc.
[0033] In this way, the first special-shaped steel bar 4311 and the second special-shaped steel bar 3412 can be matched with the special-shaped structure of the above-mentioned mold, so as to reinforce the prefabricated prefabricated stack 3 structure and ensure the reliability of the structure of the prefabricated stack 3.
[0034] In a further specific embodiment, a hook structure is further provided at the end of the first special-shaped steel bar 4311 that is not connected to the second special-shaped steel bar 3412. Thus, the reliability of the structure can be further enhanced through the hook structure.
[0035] As attached Figure 1 As shown, a wall constructed with the above-mentioned prefabricated stacks according to an embodiment of the present invention comprises sintered porous bricks 1, autoclaved aerated blocks 2, prefabricated stacks 3 and concrete lintels 4, several layers of sintered porous bricks 1 are used as the bottom, and autoclaved aerated blocks 2 are built on the sintered porous bricks 1 as the main body of the wall, and the prefabricated stacks 3 are respectively clamped in the gaps between the autoclaved aerated blocks 2 arranged in an offset manner on the left and right sides through a concrete block structure constructed by a second rectangular column formwork 33, and several prefabricated stacks 3 are stacked on each other through a concrete block structure constructed by a first rectangular column formwork 32, and a rectangular box mounting groove 7 is formed which is concave in the surface of the wall main body constructed by the autoclaved aerated blocks 2, and a concrete lintel 4 stacked with the autoclaved aerated blocks 2 on the left and right sides is installed at the upper end of the box mounting groove 7, and an autoclaved aerated block 2 is also built on the upper end of the concrete lintel 4.
[0036] In this way, the stability and reliability of the overall wall structure are ensured by using sintered porous bricks 1 as the base, autoclaved aerated blocks 2 and prefabricated stacks 3 to build the wall body and the rectangular box installation groove 7, and the concrete lintel 4 as the reinforcement.
[0037] In this embodiment, through holes such as the fire water intake 6 can be drilled on the concrete block structure constructed by the first rectangular column formwork 32 of several prefabricated stacks 3 as needed.
[0038] A construction method of the wall according to an embodiment of the present invention comprises the following steps: Several layers of sintered porous bricks 1 are laid for base laying, and the precast stacks 3 are constructed and laid together with the autoclaved aerated blocks 2. The autoclaved aerated blocks 2 are staggered and stacked to construct the main body of the wall. The sides of the two precast stacks 3 that are not constructed by the second rectangular column formwork 33 are fitted together and laid as a group. The array of precast stacks 3 are stacked on each other through the concrete block structure constructed by the first rectangular column formwork 32, and form a rectangular box installation groove 7 that is concave in the surface of the wall main body constructed by the autoclaved aerated blocks 2. The array of precast stacks 3 is respectively clamped and laid in the gaps between the autoclaved aerated blocks 2 on the left and right sides that are staggered and stacked through the concrete block structure constructed by the second rectangular column formwork 33. A concrete lintel 4 stacked with the autoclaved aerated blocks 2 on the left and right sides of the box installation groove 7 is installed at the upper end of the box installation groove 7, and the upper end of the concrete lintel 4 continues to be laid with the autoclaved aerated blocks 2 for keeping the bottom of the wall main body flush.
[0039] A specific implementation of the present invention is as follows: The above-mentioned mold for prefabricating the prefabricated pile 3 is designed using BIMMAKE software, and the mold processing diagram is designed. The template design should take into account the later installation of the fire hood. The prefabricated pile 3 can use a hanging mold. Under the condition of meeting the design requirements, considering the convenience during construction, the mold is divided into a left prefabricated pile mold 301 and a right prefabricated pile mold 302. The mold size is required to be accurate, the template joints are tightly fitted, no slurry is leaked, and the steel bars are fully tied to meet the use requirements. According to the structure of the left prefabricated pile mold 301 and the right prefabricated pile mold 302, the corresponding processed special-shaped tie bars 34 are tied, and they are required to be fully tied. Before pouring, the left prefabricated pile mold 301 and the right prefabricated pile mold 302 are sprinkled with water or coated with a release agent, and poured manually, vibrated as the pouring progresses, and covered with a film for 7 days of curing.
[0040] Before construction, check the layout dimensions, and check whether the actual axis, size, position, and elevation are consistent with the design; after the structure is accepted, clean up the slurry residue on the masonry base floor. The position of the pre-embedded reinforcement for the masonry and reinforced concrete frame columns should be accurate, and should be specifically reserved according to the total height and planned structural position. The length of the masonry in the wall should meet the design requirements.
[0041] During masonry, a 200-meter-high sintered porous brick 1 is set at the bottom of the pre-installed box position for foundation. The prefabricated stack 3 is installed together with the wall masonry. The vertical spacing meets the specifications and the modulus requirements of the masonry. The tie bars should be straight. The mortar fullness of the horizontal mortar joints in the tie bar section should be greater than 85%. Expansion bolts shall not be used to fix and weld the tie bars. The position of the tie pre-embedded bars between the masonry and the structure or structural column should be accurate, and the length of the tie in the wall should meet the design requirements. The depth of the drilled holes such as the fire water intake 6 must meet the design requirements. The cleaning of the holes requires the use of a special electric hair dryer to ensure the dust cleaning effect. Masonry can only be carried out after the wall tie bar anti-pulling test is qualified.
[0042] The mortar joints should be grouted as the masonry is laid. After each layer of blocks is laid and corrected in place, the vertical joints are filled with mortar, and then the mortar joints are tightened to a depth of 3 to 5 mm. The double-sided grouted joints of the inner and outer masonry walls make the connection between the upper, lower, left and right masonry block materials more solid, prevent wind and rain from invading the interior of the wall, and make the wall clean, neat and beautiful. A Ф6 tie wall bar is set every 600 height of the wall masonry, and a tie wall bar is set along the length of the prefabricated stack board, so that the mortar joints are full and dense. The concrete lintel 4 is installed after the prefabricated stack 3 and the autoclaved aerated block 2 are installed, and the length of the extension into the wall is not less than 250 mm.
[0043] The top wall is built close to the bottom of the beam and slab, leaving a certain gap. After an interval of 14 days, use matching bricks on both sides to lay 45°-60° oblique bricks at the bottom of the beam to fill and squeeze it tightly. The mortar joints are full and dense, and triangular concrete matching blocks are set in the middle to ensure that the masonry mortar is dense and avoid shrinkage cracks on the top of the masonry to complete the final wall construction.
[0044] When the wall of the present invention is built, prefabricated concrete precast piles 3 are used for installation, which are constructed together with the wall. After the building is completed, plastering is performed so that the plastered surface is the same as the usual masonry wall, the base treatment effect is good, and the plastering is performed in layers. By constructing according to this method, the construction quality and structural strength of the wall are improved, the reliability of the structure is increased, the maintenance cost and material cost of the part are reduced, and the expected goal of innovation and optimization is achieved.
[0045] The present invention can effectively improve the common problems of cracking and poor durability of plastering on the wall with holes. The mold is easy to construct, quick to use, simple in construction process, short in construction period, reasonable in comprehensive cost, and can reasonably utilize the concrete surplus and the short steel bar structure to reduce costs and increase efficiency. The present invention is suitable for the use of fire extinguishing boxes embedded in the wall, electric meter boxes embedded in the wall, and strong and weak current boxes in residential buildings in construction projects, etc. It can effectively ensure the construction quality, be green and environmentally friendly, save the cost of later maintenance, meet the requirements of civilized construction sites, and be energy-saving and efficient.
