Description

Technical Field

[0001] The utility model relates to the technical field of autoclaved aerated concrete blocks, in particular to the structure of a waterproof autoclaved aerated concrete block. Background Art

[0002] Autoclaved aerated concrete blocks are porous concrete products that offer excellent thermal and sound insulation, are lightweight, and are considered energy-efficient and environmentally friendly building materials. Conventional autoclaved aerated concrete blocks have poor load-bearing capacity and are primarily used for exterior infill walls and non-load-bearing interior partitions in buildings.

[0003] In the processing of autoclaved aerated concrete blocks, in order to improve space utilization, multiple blocks are often stacked up and down for simultaneous high-pressure steam curing. When the contact surfaces of adjacent blocks are smooth and in close contact, it is easy to hinder the volatilization of steam moisture and form watermarks on the contact surfaces, which not only reduces the surface quality but also further reduces the structural strength, and needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a water-mark-proof autoclaved aerated concrete block structure, thereby avoiding the generation of watermarks during high-pressure steam curing and improving the thermal insulation effect and structural strength.

[0007] Wherein, the cross-sections of the first exhaust groove, the second exhaust groove, the third exhaust groove and the fourth exhaust groove are isosceles trapezoidal structures.

[0008] Wherein, the first insulation hole is vertically connected to the second insulation hole located on the same cross section of the autoclaved aerated concrete block.

[0009] Wherein, the number of the first exhaust slot is at least one.

[0010] Wherein, the number of the third exhaust slot is at least one.

[0011] Wherein, a wire threading pipe extending along the height direction is vertically arranged in the autoclaved aerated concrete block.

[0012] Wherein, the threading pipe is a steel pipe.

[0013] The beneficial effects of the present invention are: a structure of autoclaved aerated concrete blocks that are waterproof and print-proof, and an exhaust structure is formed on the surface of the autoclaved aerated concrete blocks through the design of the first exhaust groove, the second exhaust groove, the third exhaust groove and the fourth exhaust groove, thereby improving the exhaust effect when adjacent autoclaved aerated concrete blocks are in close contact, avoiding the generation of watermarks during high-pressure steaming, ensuring structural strength, and utilizing the first insulation hole and the second insulation hole to enhance the three-dimensional exhaust effect, and after wall construction, the first insulation hole and the second insulation hole can be sealed with mortar, further enhancing the insulation effect, and when wall construction, steel bars can be passed through the threading pipes of multiple autoclaved aerated concrete blocks up and down to improve the wall construction accuracy and structural stability, and the threading pipes are utilized to enhance the compressive strength of the autoclaved aerated concrete blocks, with good load-bearing effect.

[0015] Figure 2 yes Figure 1 AA section view. DETAILED DESCRIPTION

[0016] The following combination Figures 1 and 2 The technical solution of the present utility model is further illustrated by specific embodiments.

[0017] like Figure 1 The structure of the waterproof autoclaved aerated concrete block shown in FIG. 1 includes: an autoclaved aerated concrete block 1 of rectangular structure, as shown in FIG. Figure 2 As shown, the top surface of the autoclaved aerated concrete block 1 is concavely provided with a first exhaust groove 4 extending along its length direction, and the bottom surface of the autoclaved aerated concrete block 1 is concavely provided with a second exhaust groove 6 corresponding to the first exhaust groove 4. When two adjacent autoclaved aerated concrete blocks 1 are stacked up and down, the contact parts can be exhausted through the first exhaust groove and the second exhaust groove.

[0018] The number of the first venting groove 4 is at least one. In this embodiment, the number of the first venting groove 4 is two. This facilitates the volatilization of moisture during autoclaving, preventing the formation of watermarks on the contact surfaces of two adjacent autoclaved aerated concrete blocks 1. Furthermore, the first venting groove 4 facilitates the adhesion of mortar during wall construction, thereby improving the structural stability of the wall after construction.

[0019] like Figure 2As shown, the first exhaust groove 4 is provided with a first insulation hole 5 vertically extending to the second exhaust groove 6 for vertical exhaust, thereby improving the volatilization effect of steam moisture in the autoclaved aerated concrete block 1 during high-pressure curing.

[0020] like Figure 1 As shown, the front side of the autoclaved aerated concrete block 1 is concavely provided with a third exhaust groove 2 extending along its length direction, and the back side of the autoclaved aerated concrete block 1 is concavely provided with a fourth exhaust groove 7 corresponding to the third exhaust groove 2. The third exhaust groove 2 and the fourth exhaust groove 7 strengthen the exhaust of the front and back sides of the autoclaved aerated concrete block 1, thereby avoiding the formation of watermarks on the contact surfaces of the two adjacent autoclaved aerated concrete blocks on the left and right during high-pressure steam curing.

[0021] The number of the third exhaust grooves 2 is at least one. In this embodiment, the number of the third exhaust grooves 2 is three. The three third exhaust grooves 2 are spaced apart in the upper and lower parts, which can not only improve the exhaust effect, but also improve the plastering construction effect of the front and back of the autoclaved aerated concrete block 1 after wall construction.

[0022] like Figure 2 As shown, the third exhaust slots 2 are interspersed with second insulation holes 3 extending horizontally to the fourth exhaust slots 7, further enhancing the exhaust effect. In this embodiment, the first insulation holes 5 are vertically connected to the second insulation holes 3 located on the same cross-section of the autoclaved aerated concrete block 1. The cooperation between the first insulation holes 5 and the second insulation holes 3 enhances the three-dimensional exhaust effect. Moreover, after the wall is constructed, the first insulation holes 5 and the second insulation holes 3 can be sealed with mortar, further enhancing the thermal insulation effect.

[0023] In this embodiment, the cross-sections of the first exhaust groove 4, the second exhaust groove 6, the third exhaust groove 2 and the fourth exhaust groove 7 are isosceles trapezoidal structures. The first exhaust groove 4, the second exhaust groove 6, the third exhaust groove 2 and the fourth exhaust groove 7 are automatically generated by the mold structure when the autoclaved aerated concrete blocks are cast, without the need for post-processing and with low cost.

[0024] A wire threading tube 8 extending in the height direction is vertically provided in the autoclaved aerated concrete block 1. In this embodiment, the wire threading tube 8 is a steel pipe with high strength. The wire threading tube 8 is used to improve the compressive strength of the autoclaved aerated concrete block 1 after wall construction, and has a good load-bearing effect.

[0025] When laying a wall, you can first pass the steel bars through the threading tubes 8 of multiple autoclaved aerated concrete blocks 1 to improve the wall's accuracy and structural stability. After the mortar has solidified, you can remove the steel bars from the threading tubes 8 to facilitate the subsequent threading of the building's power lines. If threading is not required, you can also keep the steel bars in the threading tubes 8 to further improve the compressive strength.

[0026] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
