Description

Technical Field

[0001] The present application belongs to the technical field of auxiliary installation equipment for cables, and specifically relates to a prefabricated bridge frame through-plate special joint. Background Art

[0002] The wiring cable bridge is an auxiliary device used for laying cables in buildings. Its main function is to provide a laying route for the cables, protect the cables from physical damage, and facilitate laying and maintenance. It also has a certain beautification and decorative effect. During construction, holes are generally reserved in the corners of the building, and cable ducts are installed in the holes. Then, cement is poured between the cable duct and the floor slab, and a duct cover is installed in the length direction of the duct. When laying the cables, the duct cover is removed and installed after the cables are laid. For example, in the prior art, a Chinese utility model patent for a "cable bridge assembly" is disclosed, with the publication number CN210201364U, which specifically discloses a cable bridge assembly, including a U-shaped groove, and a groove cover that matches the opening of the U-shaped groove, and an installation buckle is set on the groove cover. The installation opening piece is connected to the U-shaped groove to realize the installation of the cable bridge, which effectively simplifies the installation steps of the cable duct. However, when the holes of the cable bridge and the floor are fixed with concrete, they are prone to loosening, displacement or even falling off, which makes it impossible to effectively fix the cable bridge joints, affecting the stable layout of the cables and the overall safety of the building structure. In addition, the slot cover of the cable bridge is an integrated design. After it passes through the floor and is fixed, it will cause great inconvenience to the subsequent cable laying work. Once it is necessary to open the slot cover for cable layout or maintenance, it often takes a lot of time and human resources due to the difficulty of disassembly and assembly, increasing the construction cost. If the cable is directly threaded without opening the slot cover, it is easy to cause the wires to cross and tangle, which not only increases the difficulty of installation, but also may affect the heat dissipation of the cable and future maintenance work. Summary of the invention

[0003] In order to solve the above-mentioned technical problems, the present application provides a prefabricated special bridge plate joint, which is arranged between floors, including: a trough body, a cover plate, a first movable plate and a second movable plate, the cover plate is fixedly covered on the trough body, and a step is formed between the cover plate and the trough body, the length of the cover plate is less than the length of the trough body, and the cover plate is located in the middle section of the trough body; the first movable plate is slidably connected to the upper section of the trough body, and is cooperatively connected with one end of the cover plate; the second movable plate is snap-connected to the lower section of the trough body; the cover plate, the first movable plate and the second movable plate can cover the trough body in the length direction.

[0004] Preferably, a blocking piece is provided on the inner surface of the cover plate, and the blocking piece is cooperatively connected with the first movable plate.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0020] like Figures 1 to 3 As shown, the present application provides a prefabricated bridge frame special joint for penetrating plates, which is arranged between floors, including: a trough body 1, a cover plate 3, a first movable plate 2 and a second movable plate 4, the cover plate 3 is fixedly covered on the trough body 1, and a step 10 is formed between the cover plate 3 and the trough body 1, the length of the cover plate 3 is less than the length of the trough body 1, and the cover plate 3 is located in the middle section of the trough body 1; the first movable plate 2 is slidably connected to the upper section of the trough body 1, and is matched with one end of the cover plate 3; the second movable plate 4 is snap-connected to the lower section of the trough body 1; the cover plate 3, the first movable plate 2 and the second movable plate 4 can cover the trough body 1 in the length direction.

[0021] Specifically, the trough body 1 is set in a U-shaped structure, which can load cables to prevent external objects from damaging the cables. The width of the cover plate 3 is greater than the width of the trough body 1, and the two sides of the cover plate 3 in the width direction are bent inward and connected to the two outer sides of the trough body 1. The cover plate 3 is set in the middle position of the trough body 1. After the cover plate 3 is welded with the trough body 1, a step 10 is formed, and the step 10 can provide additional contact area and support points. During installation, it can play a supporting role for the entire prefabricated bridge through-plate special joint. The cover plate 3 is provided with a first movable plate 2 and a second movable plate 4 on both sides of the length direction of the trough body 1. The first movable plate 2 and the second movable plate 4 are bent at right angles on both sides of the width direction of the trough body 1 so that the first movable plate 2 and the second movable plate 4 slide on the trough body 1. The first movable plate 2 and the second movable plate 4 slide along the length direction of the trough body 1 and can partially slide into the inner side of the cover plate 3, so that the first movable plate 2 and the second movable plate 4 are respectively sealed tightly with the cover plate 3 to prevent cement from entering the prefabricated bridge through-plate special joint during installation.

[0022] When the prefabricated finished bridge frame through-plate special joint is installed through the reserved hole of the floor slab, the prefabricated finished bridge frame through-plate special joint is placed vertically, the first movable plate 2 is located at the top, and the second movable plate 4 is located at the bottom. The cover plate 3 is arranged between the first movable plate 2 and the second movable plate 4. The first movable plate 2 is matched and connected with one end of the cover plate 3 so that the first movable plate 2 is blocked when sliding into the cover plate 3 to prevent further sliding; the second movable plate 4 is clamped and installed with the trough body 1.

[0023] The above technical solution adopted by the prefabricated bridge plate-penetrating special joint provided in the present application can achieve the following beneficial effects:

[0024] The trough body 1 is provided with physical protection for the cables to prevent them from being damaged by external collision, wear and extrusion. The cover plate 3 prevents dust, moisture or other harmful substances from entering the trough body 1 and affecting the normal operation of the cables. The step 10 formed between the cover plate 3 and the trough body 1 can provide additional contact area and support points. During installation, it can support the special joints of the entire prefabricated bridge. The length of the cover plate 3 is smaller than the trough body 1, and the cover plate 3 is located in the middle section of the trough body 1, dividing the trough body 1 into an upper section and a lower section, and is respectively equipped with a slidable first movable plate 2 and a second movable plate 4 that is installed in a snap-fit ​​manner. The first movable plate 2 can be slidably connected to the upper section of the trough body 1, and can be quickly installed and repaired without having to completely open the entire bridge; the snap-fit ​​connection method of the second movable plate 4 and the trough body 1 ensures the stable closure of the lower section, and can be relatively easy to disassemble when installing cables. When laying cables, the first movable plate 2 and the second movable plate 4 can be removed, so that during the installation process, it is possible to avoid opening too long a bridge at one time, which is simple to disassemble and assemble, saves time and reduces labor costs. It is also convenient for cable laying operations in a limited space, and when threading, it is easy to operate without causing the wires to cross or entangle, and provides convenience for future maintenance work. This prefabricated bridge frame through-plate special joint structure can be pre-embedded in the wall or floor during the construction stage, ensuring standardization and normalization of cable laying in the later stage, reducing secondary damage to the building structure, and improving engineering quality and construction efficiency.

[0025] In a preferred embodiment, a baffle 13 is provided on the inner surface of the cover plate 3 , and the baffle 13 is cooperatively connected with the first movable plate 2 .

[0026] A baffle 13 is provided on the inner surface of the cover plate 3, and the baffle 13 and the first movable plate 2 form a mutually cooperating and restricting relationship. Specifically, the baffle 13 is provided on the inner side wall of the cover plate 3 adjacent to the first movable plate 2, and its direction is perpendicular to the length direction of the trough body 1, which can effectively limit the first movable plate 2. The baffle 13 extends to a position of 1 cm in the direction of the bottom of the trough body 1, which can ensure that the baffle 13 provides a stable supporting force when the first movable plate 2 moves to a certain position. During the actual installation and use process, when the first movable plate 2 moves downward, the baffle 13 will timely contact and prevent it from falling further, thereby playing a role in limiting and preventing overshoot, and effectively ensuring the stability and safety of the entire device or component.

[0027] In a preferred solution, folded edges 11 are provided on both sides of the trough body 1 in the length direction, and the first movable plate 2 and the second movable plate 4 move along the folded edges 11 .

[0028] Specifically, both side edges of the trough body 1 in the length direction are folded inward to form folded edges 11, which increases the strength and rigidity of the edge of the trough body 1 and also provides a stable guiding path for the first movable plate 2 and the second movable plate 4.

[0029] In the wiring of a building, concealed wires need to be laid on the floor, so a plurality of first wire threading holes 7 are provided on one side of the trough body 1 .

[0030] Specifically, a plurality of first threading holes 7 are evenly spaced on one side of the trough body 1. For example, the number of the first threading holes 7 is 2 to 4, and a cable is placed in each first threading hole 7 to avoid interference between cables. When threading, the cable is passed through an opening at one end of the trough body 1 in the length direction, and then passed through the first threading hole 7 and placed on the floor.

[0031] In a preferred embodiment, a first connecting tube 5 is provided on the first threading hole 7 , and a tightening component 6 is provided on the first connecting tube 5 .

[0032] Specifically, the first threading hole 7 is fixed with the first connecting tube 5, and the first connecting tube 5 is made of a special material, such as metal, and is mainly used to lay special cables. It has fire retardant properties and improves the safety of the cables. The first connecting tube 5 can be composed of a threaded tube and a threaded sleeve, and the threaded tube and the threaded sleeve are respectively connected to the two sides of the first threading hole 7, and the thread is locked on the first threading hole 7. The connecting tube outside the trough body 1 is provided with a threaded hole and a tightening component 6, and the tightening component 6 can be a screw used in conjunction with the threaded hole, and a concave leather pad is provided at the tip of the screw. When the special cable passes through the first connecting tube 5, the special cable is fixed by the screw through the threaded hole to prevent the special cable from shaking and being damaged when passing other cables. The concave leather pad can reduce the damage to the special cable when being locked. The first connecting tube 5, as a channel for the wire, can be connected to the concealed wire tube on the floor to effectively protect the cables passing therethrough from being damaged. The first connecting tube 5 can be used to orderly organize and fix the lines, so that the overall layout is more regular, which is convenient for later maintenance and overhaul work.

[0033] In a preferred embodiment, a plurality of second threading holes 8 are provided at the bottom of the trough body 1 and on the side of the trough body 1 opposite to the first threading hole 7 .

[0034] Specifically, a plurality of second threading holes 8 are provided at the bottom of the trough body 1 and on the other side of the trough body 1. For example, 4 to 6 second threading holes 8 are provided at the bottom of the trough body 1, and 2 to 4 second threading holes 8 are provided on the side of the trough body opposite to the first threading holes 7. The second threading holes 8 are used for laying ordinary cables.

[0035] Based on the above solution, a more preferred implementation scheme is that a second connecting tube 9 is provided on the second threading hole 8 .

[0036] Specifically, the second threading hole 8 is fixedly provided with a second connecting tube 9, and the material of the second connecting tube 9 is selected as a PVC tube, which is used to pass ordinary cables. The connection method of the second connecting tube 9 is the same as the connection method of the first connecting tube 5 (no further description). As a passage for the wire, the second connecting tube 9 can be connected to the concealed wire tube on the floor, effectively protecting the cables passing through it from damage. The second connecting tube 9 can be used to orderly organize and fix the lines, making the overall layout more regular and facilitating later maintenance and repair work.

[0037] In a preferred embodiment, a plurality of positioning holes 12 are provided on the tank body 1 .

[0038] Specifically, a number of positioning holes 12 are designed and processed on the two sides and the bottom of the trough body 1. During installation and pouring, bolts, pins and other connectors can be used in conjunction with the positioning holes 12 to achieve precise docking and fixation with the floor slab, thereby ensuring the stability and accuracy of the overall structure.

[0039] The specific installation process is as follows:

[0040] First, remove the first movable plate 2 and the second movable plate 4 from the trough body 1 to facilitate the installation of the prefabricated finished bridge through-plate special joint. The step 10 on the prefabricated finished bridge through-plate special joint is accurately placed on the support pre-set in the hole of the floor slab, so that the cover plate 3 and the middle section of the trough body 1 are placed in the hole of the floor slab, and the horizontality and verticality of the prefabricated finished bridge through-plate special joint are ensured. The first connecting pipe 5 and the second connecting pipe 9 are respectively firmly connected to the corresponding wire pipes previously laid in the groove to ensure smooth and unobstructed lines. Select bolts of appropriate specifications, pass through the positioning holes 12 on the trough body 1 one by one, and place the bolts, the sides of the trough body 1 and the bottom of the trough together in the pre-prepared cement slurry for pouring. In this process, ensure that the bolts are firmly embedded in the cement, so as to achieve a close combination between the trough body 1 and the cement foundation, and ensure its stability and safety. Finally, reinstall the first movable plate 2 and the second movable plate 4 that were previously removed back to the trough body 1 to form a complete structure.

[0041] The above-described embodiments only express the way of equipment layout of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application; it should be pointed out that for ordinary technicians in this field, several adjustments and improvements can be made without departing from the concept of the present application, which all belong to the scope of protection of the present application; therefore, the scope of protection of the patent of this application should be based on the attached claims.
