Description

Technical Field

[0001] The invention relates to the technical field of assembled buildings, and in particular to the field of autoclaved lightweight aerated concrete slabs. Background Art

[0002] Autoclaved lightweight aerated concrete is referred to as ALC. Strip boards made of ALC are called ALC strip boards.

[0003] According to "Autoclaved Lightweight Aerated Concrete Board" GB15762-2008, the length L of the existing ALC strip is generally 3000-7000mm, the width B is generally 600mm, and the thickness D is generally 75-300mm; the ALC strip has two large faces, two end faces and two side faces, the two side faces are splicing faces, one side is provided with convex strips, and the other side is provided with grooves, and the convex strips and the grooves are adapted to each other, as shown in Figure A.1 of "Autoclaved Lightweight Aerated Concrete Board" GB15762-2008. When the ALC strip is installed, the sides of two adjacent ALC strips are spliced ​​together, and the convex strips and the grooves are closely fitted to form a board seam, and anti-cracking measures are taken between the board seams, and finally a continuous vertical wall panel or horizontal floor slab is formed.

[0004] Pipe holes for installing cables, optical cables, etc. often need to be opened on the wall panels. The traditional construction method is to manually dig vertical pipeline grooves, then bury pipes, thread wires, and finally repair the wall surface with mortar. In the traditional construction process, the workload is large, the dust is high, and a lot of decoration garbage and decoration dust are generated. Wet operations are required, the labor cost is high, and the construction period is consumed. The patent with publication number CN109016126A and announcement date 2018.12.18 discloses a method for pre-embedded pipelines based on prefabricated building wall panels: first, establish a model, pre-layout the board and virtually locate the embedded pipeline parts; then, intercept the embedded pipeline parts and arrange the embedded pipeline parts; finally, make the finished wall panels, and form board pipeline holes at the location where the embedded pipeline parts are arranged. Among them, the embedded pipeline parts are high-temperature resistant pipes, hot-melt rods, or smooth metal rods that can be pulled out. ALC strips need to be steamed under high temperature and high pressure. Pipeline embedded parts are made of ordinary plastic or polymer pipes, which are easy to deform during the steaming process, affecting the properties of the material and producing polluting gases. If metal pipes are used for pipeline embedded parts, the cost is high. From the construction process point of view, the pre-buried pipeline embedded parts form the pipeline holes of the plate. Although the construction is simple, the position and number of the pipelines are fixed. If the position and number of switches, sockets, faucets, etc. need to be adjusted later, large-scale manual grooving is still required. Summary of the invention

[0005] The present invention firstly provides an ALC strip board, which solves the problem that pipeline holes of the existing ALC strip boards need to be manually dug, or the pipeline holes are located inside the ALC strip boards, resulting in cumbersome construction.

[0006] The technical solution adopted by the present invention to solve the technical problem is: ALC strip, both sides of the ALC strip are splicing surfaces, the shapes of the two splicing surfaces are adapted to each other, and the two splicing surfaces can be butt-jointed to form a pipeline hole.

[0007] Specifically: the cross-section of the pipeline hole is hexagonal, rectangular, trapezoidal, circular, elliptical, semicircular, crescent-shaped or shuttle-shaped.

[0008] Furthermore, the center line of the pipeline hole is located in the middle of the side surface of the ALC strip.

[0009] Furthermore, a protective sheet is provided on the entire surface of at least one side surface of the ALC strip, or a protective sheet is provided on a portion of at least one side surface of the ALC strip used for forming pipeline holes.

[0010] Furthermore, the retaining pieces are arranged at intervals in the pipeline hole or continuously in the entire pipeline hole, the retaining pieces are through holes along the direction of the pipeline hole, and the cross-sectional shape of the retaining pieces is consistent with the cross-sectional shape of the pipeline hole.

[0011] Furthermore, the cross section of the clamping piece is closed or open, and the clamping piece is made of metal or polymer material.

[0012] Furthermore, the pipeline holes are provided with positioning pieces at intervals, and one side of the ALC strip is used to form a positioning piece slot for the position of the pipeline hole, and the positioning piece is installed in the positioning piece slot.

[0013] Specifically: the two joint surfaces of the ALC strip board are connected by concave-convex connection, convex-convex connection or concave-concave connection to form a pipeline hole; wherein, concave-convex connection means: grooves and convex strips are respectively arranged on the two sides of the ALC strip board, the two joint surfaces of the ALC strip board are spliced, the convex strip is located in the groove, the protruding height of the convex strip is less than the depth of the groove, and a pipeline hole is formed between the convex strip and the groove; convex-convex connection means: convex strips are respectively arranged on the two sides of the ALC strip board, one side of one convex strip is flush with one large surface of the ALC strip board, and one side of the other convex strip is flush with another large surface of the ALC strip board, the two joint surfaces of the ALC strip board are spliced, and a pipeline hole is formed between the two convex strips; concave-concave connection means: grooves are respectively arranged on the two sides of the ALC strip board, the two joint surfaces of the ALC strip board are spliced, and a pipeline hole is formed between the two grooves.

[0014] The present invention also provides a method for forming pipeline holes in an ALC strip plate, wherein two of the above-mentioned ALC strip plates are spliced ​​at the side to form pipeline holes between the spliced ​​surfaces.

[0015] Furthermore, before the two ALC strips are spliced ​​together, a port groove is constructed on the side of the ALC strip, and the port groove is connected with the pipeline hole; after the two ALC strips are spliced ​​together at the side, the port groove forms a pipeline port installation position.

[0016] The beneficial effects of the present invention are as follows: the ALC strip has a simple structure and is easy to manufacture. The pipeline hole wall is already manufactured when the ALC strip is manufactured. When the ALC strip is installed, a complete pipeline hole is naturally formed at the joint after the joint is connected. The construction accuracy is high, and there is no need to manually dig a large number of pipeline holes in the later stage. The production cost of the ALC strip is almost not increased, but a large amount of labor and management costs can be saved, and the construction period is also saved. Most of the ALC strip pipeline hole forming methods are dry methods, which reduce noise, dust, construction waste and other pollution.

[0017] The pipeline holes are arranged along the joint surface of the ALC strips. There are many pipeline holes and they are evenly spaced, which is convenient for flexible arrangement of pipelines. It is easier and more convenient to add or adjust the position of pipelines during the later renovation process of the owner. The protective sheet on the side of the ALC strips can improve the quality of the holes and protect the side of the strips from damage during transportation or construction. The clamping piece enhances the strength of the joint surface of the ALC strips, that is, enhances the strength of the ALC that forms the pipeline holes, and can protect the pipelines. When the two joint surfaces are concavely butted, the clamping piece is set at intervals in the pipeline hole, and the clamping piece can limit the displacement of the strip parts.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] The ALC strip of the present invention has two side surfaces, both of which are splicing surfaces. The shapes of the two splicing surfaces are adapted to each other, so that the two ALC strips can be spliced ​​through the side surfaces, and the two splicing surfaces can be butted to form a pipeline hole 1. During construction, the two ALC strips are spliced ​​through the side surfaces to form a continuous vertical wall panel or horizontal floor slab, and the shapes of the two spliced ​​side surfaces are the same as the shapes of the two side surfaces of a single ALC strip.

[0025] First embodiment

[0026] like Figures 1 to 4 As shown, the ALC strips of the present invention have concave-convex joints between the joint surfaces, that is, grooves and convex strips are respectively arranged on the two sides of the ALC strips, the depth of the grooves is greater than the height of the convex strips, the two joint surfaces of the ALC strips are spliced, the convex strips are located in the grooves, and a pipeline hole 1 is formed between the convex strips and the grooves.

[0027] The shape of the pipeline hole 1 is determined by the shapes of the grooves and the convex strips. The cross section of the pipeline hole 1 can be trapezoidal, square, semicircular and crescent-shaped. Figures 1 to 4 In addition, the cross section of the pipeline hole 1 can also be hexagonal, rectangular, circular, elliptical, or shuttle-shaped, etc. The center line of the pipeline hole 1 is preferably located in the middle of the side of the ALC strip.

[0028] The two sides of the ALC strip can be autoclaved lightweight aerated concrete, or protective sheets can be set on one or both sides. The protective sheets can be arranged continuously or at intervals. The protective sheets are used to ensure the shape of the side of the ALC strip, and also make the wall of the pipeline hole 1 smoother, thus protecting the internal pipeline. The protective sheets also have the function of protecting the ALC strip during transportation or construction, so that the side of the ALC strip is not easily damaged.

[0029] A clamping piece 3 can also be arranged in the pipeline hole 1. The clamping piece 3 is a through hole along the direction of the pipeline hole 1. The cross-sectional shape of the clamping piece 3 is consistent with the cross-sectional shape of the pipeline hole 1, and the through hole of the clamping piece 3 becomes the pipeline hole 1. Since the groove on one side of the ALC strip is deep, the clamping piece 3 is stuck in the groove, which can increase the strength of the autoclaved lightweight aerated concrete at the groove. The clamping piece 3 can be arranged continuously, that is, the clamping piece 3 is arranged in the entire groove, or the clamping piece 3 is arranged at intervals in the groove. The continuous arrangement of the clamping piece 3 can protect the wires or pipelines on other buildings. At the same time, due to the deepening of the groove on the side of the ALC strip, the corner of the groove is prone to stress concentration, and the length of the autoclaved lightweight aerated concrete around the two sides of the groove is increased, which is easy to be damaged under external force. The continuous clamping piece 3 is arranged in the groove, and the clamping piece 3 can improve the force and reduce the risk of damage to the ALC strip during transportation, hoisting and installation.

[0030] The cross-section of the clamping member 3 is of a closed type or an open type. The open type means that the cross-section of the clamping member 3 has at least one opening, such as in the shapes of C, ∪, ∩,凵,冂,匚; the closed type means that the cross-section of the clamping member 3 is a closed shape, such as a quadrilateral, a polygon, a circle, etc. The splicing surfaces of the ALC slabs are in concave-convex butt joint, and the clamping member 3 in the side groove is preferably of the closed type. The clamping member 3 is made of metal or polymer material, such as alloy profile or steel pipe.

[0031] The clamping member 3 can be adhesively fixed in the side groove of the ALC slab or fixed to the ALC slab by screws. When the clamping members 3 are arranged at intervals in the side groove of the ALC slab, for example, arranged at an interval of 600 mm, clamping member grooves can also be arranged at intervals in the side groove of the ALC slab. The shape of the clamping member groove is the same as that of the clamping member 3 and is formed during the production of the ALC slab. The clamping member 3 is directly installed in the clamping member 3 groove before splicing to ensure the accuracy of the installation spacing and position.

[0032] Second Embodiment

[0033] As Figures 5 to 8 shown, for the ALC slab of the present invention, the splicing surfaces are in convex-convex butt joint. The two sides of the ALC slab are respectively provided with convex strips. One side of one convex strip is flush with one large surface of the ALC slab, and one side of the other convex strip is flush with the other large surface of the ALC slab. When the two splicing surfaces of the ALC slab are spliced, a pipeline hole 1 is formed between the two convex strips. The shape of the pipeline hole 1 is determined by the shapes of the two convex strips. For the specific shape of the pipeline hole 1, refer to the description of the pipeline hole 1 in the above first embodiment.

[0034] To avoid damage to the convex strips during the transportation and hoisting of the ALC slab, a protective sheet 2 can be provided on the entire surface of one or both sides of the ALC slab, or the protective sheet 2 is only provided on the part of the side of the ALC slab where the pipeline hole 1 is formed. The protective sheet 2 can be arranged continuously, that is, arranged entirely along the extension direction of the pipeline hole 1; or arranged at intervals, and the protective sheet 2 is arranged at the parts prone to damage, such as the ends and the middle of the side of the ALC slab. The protective sheet 2 forms the pipeline hole 1 after the ALC slabs are spliced. The protective sheet 2 is preferably a metal sheet to ensure strength. The protective sheet 2 can also protect the pipelines passing through the pipeline hole 1. The protective sheet 2 can be fixedly connected to the two sides of the ALC slab by screws, bolts, etc., or adhered to the two sides of the ALC slab. The cross-section of the protective sheet 2 can be a right angle, an obtuse angle, an arc or a semi-circle, as Figures 5 to 8 shown.

[0035] Third Embodiment

[0036] As Figures 9 to 20As shown, for the ALC slab of the present invention, the splicing surfaces are concave-concave butt joints. Grooves are respectively provided on two side surfaces of the ALC slab. When two splicing surfaces of the ALC slab are spliced, the two grooves jointly form a pipeline hole 1. The shape of the pipeline hole 1 is determined by the shapes of the two grooves. For the specific shape of the pipeline hole 1, refer to the description of the pipeline hole 1 in the above first embodiment.

[0037] Since the two splicing surfaces of the ALC slab are concave-concave butt joints, misalignment between the ALC slabs cannot be prevented after splicing. A positioning member 3 is arranged in the groove on the side surface of the ALC slab, that is, the positioning member 3 is arranged at intervals in the pipeline hole 1 or continuously arranged throughout the pipeline hole 1. The through hole of the positioning member 3 along the direction of the pipeline hole 1 becomes the pipeline hole 1. The cross-sectional shape of the positioning member 3 is the same as the cross-sectional shape of the pipeline hole 1. After the ALC slabs are spliced through the side surfaces, the positioning member 3 is stuck in the grooves of two adjacent side surfaces, playing a role in preventing misalignment. The positioning member 3 also has the effect of increasing the strength of the autoclaved lightweight aerated concrete at the groove. The positioning member 3 can be continuously arranged, that is, the positioning member 3 is arranged throughout the groove, or the positioning member 3 is arranged at intervals in the groove. The positioning member 3 can be fixedly pasted in the groove on the side surface of the ALC slab or fixed to the ALC slab by screws. When the positioning member 3 is arranged at intervals in the groove on the side surface of the ALC slab, the interval can be 600 mm. Positioning member grooves can also be arranged at intervals in the groove on the side surface of the ALC slab. The shape of the positioning member groove is the same as the shape of the positioning member 3 and is formed during the production of the ALC slab. Before splicing, the positioning member 3 is directly installed in the positioning member groove to ensure the accuracy of the installation spacing and position.

[0038] The cross-section of the positioning member 3 is of a closed type or an open type. The open type means that the cross-section of the positioning member 3 has at least one open shape, such as presenting the shapes of C, ∪, ∩,凵,冂 or匚, and can also be a polygon; the closed type means that the cross-section of the positioning member 3 is a closed shape, such as a quadrilateral, a polygon, a circle, etc. The positioning member 3 is made of metal or a polymer material, such as an alloy profile or a steel pipe.

[0039] For example, as Figures 9 to 12 shown, the overall contour of the cross-section of the positioning member 3 is hexagonal. The positioning member 3 can be a closed-type hexagon, as Fig. 9 shown; or the positioning member 3 can be an open-type hexagon. Before splicing the positioning member 3, the positioning member 3 is fixed to one side surface of the ALC slab, and the opening of the positioning member 3 can be located inside or outside the groove, as Fig.11 and Fig.10As shown. The clamping piece 3 is open-end, so that the size of the clamping piece 3 can be finely adjusted, which is convenient for splicing the ALC strips. The clamping piece 3 can be a whole, that is, no matter whether the clamping piece 3 is closed or open, each clamping piece 3 is a component; in addition, the clamping piece 3 can also be two parts, and the clamping piece 3 is in a "<>" shape, that is, the clamping piece 3 is two pieces, which are respectively set at the joints of the pipeline hole 1, such as Fig.12 shown.

[0040] For example, Figures 13-16 As shown, the overall cross-sectional profile of the clamping member 3 is rectangular. The clamping member 3 can be a closed rectangular shape, such as Fig.13 Alternatively, the positioning member 3 may be an open rectangular shape. Before the positioning member 3 is spliced, the positioning member 3 is fixed to one side of the ALC strip. The opening of the positioning member 3 may be located inside or outside the groove, such as Fig.15 and Fig.14 In addition, the clamping member 3 can also be composed of two parts, in a "||" shape, that is, the clamping member 3 is composed of two pieces, which are respectively arranged at the joints of the pipeline hole 1, as shown in FIG. Fig.16 shown.

[0041] For example, Figures 17-20 As shown, the overall cross-sectional profile of the clamping member 3 is circular. The clamping member 3 can be a closed circular shape, such as Fig.17 The clamping piece 3 can also be an open rectangle. Before the clamping piece 3 is spliced, the clamping piece 3 is fixed to one side of the ALC strip. The opening of the clamping piece 3 can be located inside or outside the groove. Fig.19 and Fig.18 In addition, the clamping member 3 can also be composed of two parts, in a "()" shape, that is, the clamping member 3 is composed of two pieces, which are respectively arranged at the joints of the pipeline hole 1, such as Fig. 20 shown.

[0042] The pipeline hole forming method of the ALC strip board in the present invention comprises joining two ALC strip boards at the side to form a pipeline hole 1 between the joining surfaces. Before joining the two ALC strip boards, a port groove is constructed on the side of the ALC strip board, and the port groove is connected to the pipeline hole 1; after joining the two ALC strip boards at the side, the port groove at the joint seam 6 forms a pipeline port installation position 4, and the pipeline port installation position 4 is used to install a socket or a switch box. The upper and lower ends of the ALC strip board are respectively fixed by fixing members 5, such as Fig.21 The port groove can be cut on site before splicing the ALC strips according to the socket and switch elevation; or the port groove can be reserved when manufacturing the ALC strips.
