Description

Technical Field

[0001] The invention relates to a prefabricated strip board which is convenient for installing wall facilities. Background Art

[0002] Conventional cement-based prefabricated strips can be assembled quickly, but the product itself usually does not have preset installation locations for water, electricity and weak current terminal devices. After the wall is built, the channels and ports for arranging pipelines in the wall need to be sawed and grooved according to the needs of water and electricity equipment. This is not only costly to implement, but also has low precision. At the same time, the dust increases pollution, and the need for plugging in the later stage wastes more work time, and also damages the strength of the strip itself. Summary of the invention

[0003] The object of the present invention is to solve the above technical problems and provide a prefabricated strip board which is convenient for the installation of wall facilities and has a reserved installation position for the terminal device of the water and electricity equipment.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A prefabricated strip board for easy installation of wall facilities comprises a strip board body, a top keel and a leveling foot. Structural core pulling holes are provided at both ends of the strip board body. A pipeline core pulling hole is provided between the structural core pulling holes at both ends. The pipeline core pulling hole deviates from the center line of the strip board body in the thickness direction. A mounting groove connected to the pipeline core pulling hole is provided on the side wall of the strip board body near the pipeline core pulling hole. The mounting groove is a transverse mounting groove. The top of the strip board body is connected to the top keel. The pipeline core pulling hole is located on one side of the top keel so that the pipeline can easily pass through or pass through the pipeline core pulling hole from the side of the top keel. The lower end of the structural core pulling hole of the strip board body is plugged with the leveling foot. A spacing is left between the leveling foot and the strip board body for the pipeline to pass through the pipeline core pulling hole.

[0006] Furthermore, the top keel includes two L-shaped plates arranged back to back with a spacing therebetween, a fireproof board is filled between the vertical sections of the two L-shaped plates, the vertical sections of the two L-shaped plates are connected by rivets, and the horizontal sections of the two L-shaped plates are respectively connected to the roof.

[0007] Furthermore, the vertical section of the top keel is connected to the upper end of the strip body through a connecting piece, and the connecting piece is vertically bent and includes an upper vertical plate connected to the top keel, a horizontal plate and a lower vertical plate connected to the strip body, the lower end of the upper vertical plate is vertically connected to one end of the horizontal plate, and the other end of the horizontal plate is vertically connected to the upper end of the lower vertical plate, and the upper vertical plate and the lower vertical plate are respectively provided with vertical long strip holes.

[0008] Further, the leveling foot includes a base, a bolt and a wing-shaped bracket. The head of the bolt is provided with a riveting post arranged opposite to the screw rod. The bolt is movably riveted to the base through the riveting post. A locking nut is screwed onto the screw rod of the bolt, and the wing-shaped bracket is screwed onto the screw rod above the locking nut.

[0009] Further, the wing-shaped bracket includes a T-shaped nut, a supporting plate and tube fins. The T-shaped nut is screwed onto the screw rod.

Specific implementation manners

[0024] See Figures 1 to 7 As shown, a precast strip board for facilitating the installation of wall facilities includes a strip board body 1, a top keel 2 and leveling feet 3. Structural core extraction holes 11 are opened at both ends of the strip board body 1, and pipeline core extraction holes 12 are provided on the strip board body between the structural core extraction holes at both ends. The pipeline core extraction holes 12 deviate from the center line L in the thickness direction of the strip board body and are close to the side wall of the strip board body where the pipeline core extraction holes 11 are located, and an installation groove 13 communicating with the pipeline core extraction holes 11 is opened. The top of the strip board body 1 is connected to the top keel 2, and the pipeline core extraction holes 11 are located on one side of the top keel 1 and are not blocked by the top keel, so that pipelines can penetrate into or out of the pipeline core extraction holes from one side of the top keel 2. The lower end of the structural core extraction hole 11 of the strip board body 1 is inserted with the leveling feet 3, and a spacing for pipelines to penetrate into the pipeline core extraction holes is left between the leveling feet 3 and the strip board body 11.

[0025] The installation groove is a horizontal notch. Usually, the installation height of wall facilities follows certain rules. Under the premise of refined design, the range of horizontal adjustment of facilities is not large. Therefore, installation grooves are provided at the general height, and the horizontal adjustable margin provided by the installation grooves can meet the requirements of most installations.

[0026] Starting from the industrial manufacturing concept and based on refined design, in combination with the application of assembled decorative layers, the present invention provides a wall component that cancels on-site secondary transformation and facilitates the installation of terminal facilities. When the wall has an installation groove for accommodating an embedded box and the installation groove communicates with a pipeline core extraction hole, the installation requirements of quite a number of facilities can be met.

[0027] In practical applications, some small terminal facilities (such as switches, sockets, sensors, lamps, invisible speakers, power converters, etc.) can usually be installed in embedded boxes (including 86 boxes, 120 boxes, and other custom-sized boxes). Therefore, when the wall has an installation groove for accommodating the embedded box and the installation groove communicates with the pipeline core-pulling hole, at the same time, some facilities such as hidden water mixers can also be placed into the wall using the space provided by the installation groove. Therefore, the slat body with the installation groove and the pipeline core-pulling hole can meet the requirements of most wall facilities without the need for on-site grooving.

[0028] Such as Figure 2 , Figure 5 As shown, the top keel 2 includes two L-shaped plates 21 arranged at intervals back to back. A fireproof board 22 is filled between the vertical sections of the two L-shaped plates 21, and the thickness of the fireproof board 22 is about 10 mm. The thickness of the top keel is formed by the width in the horizontal direction of the two vertical sections and the fireproof board between them. The vertical sections of the two L-shaped plates are connected by rivets 23, and the horizontal sections of the two L-shaped plates are respectively connected to the roof or the structural beam. A gap is left between the top keel 2 and the slat body 1, and it is sealed with a flexible material after the wall installation is completed. The top keel can also be T-shaped.

[0029] The vertical section of the top keel is connected to the upper end of the slat body by a connector 4. As Figure 6 shown, the connector 5 is vertically bent, including an upper vertical plate 41 connected to the top keel 2, a horizontal plate 42, and a lower vertical plate 43 connected to the slat body. The lower end of the upper vertical plate 41 is vertically connected to one end of the horizontal plate 42, and the other end of the horizontal plate 42 is vertically connected to the upper end of the lower vertical plate 43. Vertical long holes are respectively opened on the upper vertical plate and the lower vertical plate. The connector can be connected with the top keel with an up-and-down dislocation, achieving a greater tolerance margin.

[0030] An L-shaped groove is opened on the wall surface of the slat body that fits the lower vertical plate of the connector. The lower vertical plate 43 of the connector is located in the L-shaped groove 14 and is flush with the wall surface of the slat body after installation.

[0031] Leveling feet are respectively installed in the structural core-pulling holes at both ends of the slat body. As Figure 3 , Figure 7 and Figure 8As shown, the leveling foot 3 includes a base 31, a bolt 32, and a fin-shaped bracket 33. The head of the bolt 33 is extended with a riveting post 34 arranged opposite to the screw rod. The bolt 32 is movably riveted to the base 31 through the riveting post. The screw rod of the bolt is also screwed with a locking nut 35. After the height adjustment of the strip body is completed, the locking nut 35 is screwed upward until it is locked with the T-shaped nut 331 to ensure that it will not loosen during subsequent use. The fin-shaped bracket 33 is screwed on the screw rod above the locking nut. By turning the head of the bolt, the rotation of the bolt 32 is realized, and the rotation of the bolt 32 drives the up and down linear movement of the fin-shaped bracket 33. The base is non-circular, preferably square, and is located in the groove of the floor joist 6. When the bolt rotates, the base does not rotate accordingly.

[0032] The fin-shaped bracket 33 includes a T-shaped nut 331, a supporting plate 332, and tube fins 333. The T-shaped nut 331 is screwed on the screw rod of the bolt 32. The supporting plate 332 is sleeved on the small-diameter section of the T-shaped nut 331 and pressed against the stepped surface of the T-shaped nut. The tube fins 333 are sleeved on the small-diameter section of the T-shaped nut 331, and the fins of the tube fins 333 abut against the inner wall surface of the pipeline core-pulling hole 11 of the strip body. When the foundation ground is uneven, the strip body can be made horizontal and vertical by adjusting the leveling feet at both ends of the strip body, eliminating the need for leveling the ground or the floor joist in the prior art when installing the strip body. At the same time, there is a gap between the supporting plate and the floor joist to facilitate the outward extraction of the pipeline passing through the pipeline core-pulling hole or the routing of the pipeline into the pipeline core-pulling hole. The arrangement of the leveling feet can also make the slat body processed into a standard height.

[0033] The tube fins are made of elastic material to ensure that a fixing effect can be achieved regardless of the aperture size of the core-pulling hole. The tube fins include a tube body and six square sheet bodies evenly spaced on the outer wall of the tube body.

[0034] For the sake of easy understanding, it should be briefly mentioned that there is also an application filed synchronously with this application, with the title of "Prefabricated Cementitious Wall Unit with Pipeline Passing Function (such as Figure 9As shown, the markings of this part are different from those of the original application for the purpose of distinguishing it from this application. It includes a core-pulling precast slab (10), a top keel (20), and a leveling foot (30). A pipeline (40) passes through the core-pulling hole (100) of the core-pulling precast slab. The upper end of the core-pulling precast slab is connected to the top keel. The top keel is located above the core-pulling hole and the thickness of the top keel is less than the aperture of the core-pulling hole, so that part of the core-pulling holes on both sides of the top keel are not blocked. An open wire slot (50) for routing pipelines is formed above the unblocked core-pulling precast slab. An enlarged opening (101) is provided at the upper end of the core-pulling hole of the core-pulling precast slab to facilitate the pipeline to pass out along the enlarged opening from the core-pulling holes on both sides of the top keel. The lower end of the core-pulling hole of the core-pulling precast slab is inserted with the leveling foot for adjusting the flatness of the core-pulling precast slab. A wire routing space (60) for the pipeline to penetrate into its core-pulling hole is left between the leveling foot and the core-pulling precast slab. The difference between the two applications lies in the different structures of the slab body and the core-pulling precast slab. The two applications can be used in a matching manner on-site. By using the prefabricated cement-based wall unit that can pass pipelines for wiring, small terminal facilities can be installed using this application after the purpose is achieved.

[0035] In the present invention, the on-site operation cycle can be shortened, which is very valuable for projects with a high degree of standardization such as long-term rental apartments, dormitories, hotels, and wards, and which can benefit from a short construction period.
