Description

Technical Field

[0001] The present application relates to the technical field of building decoration, and in particular to a floor heating floor decoration expansion joint structure. Background Art

[0002] Floor heating, also known as radiant floor heating, uses the entire floor as a radiator. Heat is evenly heated through the floor's radiant layer, and heat is transferred to the interior of the room through radiation and convection, achieving comfortable heating. Floor heating is categorized by heat transfer medium into water-based and electric floor heating, and by the different paving structures into dry and wet floor heating.

[0003] In recent years, floor radiant heating technology has been increasingly used in residential projects, but the problem of floor cracks in initial renovation projects has always been a common quality problem in floor heating projects. Moreover, the cracks are difficult to repair and the effect is not good, which directly affects the delivery of the building.

[0004] Therefore, the Technical Code for Radiant Heating and Cooling JGJ 142-2012 clearly stipulates that when the ground area exceeds 30 m2 or the side length exceeds 6 meters, expansion joints should be set at intervals of no more than 6 meters; expansion joints are structural joints used to compensate for the expansion or contraction of concrete filling layers and surface layers. They are a very important part of the design of floor radiant heating projects and are intended to prevent the ground from being damaged by thermal expansion and contraction.

[0005] The existing floor heating floor decorative expansion joint structure includes a mortar leveling layer and an insulation layer laid on the floor slab in sequence, floor heating pipes are laid on the insulation layer, a concrete layer covering the floor heating pipes is laid on the insulation layer, decorative panels are laid on the concrete layer, expansion joints are provided between adjacent concrete layers and adjacent decorative panels, and the expansion joints are filled with filling strips; while the floor heating pipes are being laid, the filling strips are placed in designated positions, and multiple floor heating pipes pass through the filling strips. After the floor heating pipes are laid, the concrete layer and decorative panels are constructed, so that expansion joints are automatically formed at the location of the filling strips.

[0006] Regarding the above-mentioned related technologies, since the filling strips have low hardness and elasticity, when filling concrete, the positions of the filling strips not penetrated by the floor heating pipes are prone to positional displacement, resulting in irregular expansion joints. Summary of the Invention

[0007] In order to improve the position stability of the filling strip during construction and make the formed expansion joint more in line with the specification requirements, the present application provides a floor heating floor decorative expansion joint structure.

[0008] The present application provides a floor heating floor decorative expansion joint structure adopting the following technical solutions:

[0009] A floor heating floor decorative expansion joint structure comprises a mortar leveling layer, a waterproof layer and an insulation layer sequentially laid on the floor slab from bottom to top, a plurality of floor heating pipes laid on the insulation layer, a plurality of elastic filling strips are placed on the insulation layer, the lower surfaces of the elastic filling strips are in contact with the insulation layer, and parts of the elastic filling strips are penetrated by a plurality of floor heating pipes; a plurality of auxiliary positioning mechanisms for fixing the positions of the elastic filling strips not penetrated by the floor heating pipes are provided on the insulation layer, and the auxiliary positioning mechanisms are arranged along the length direction of the filling strips; a concrete layer covering the floor heating pipes is laid on the insulation layer, and decorative panels are laid above the concrete layer, and the positions of the elastic filling strips in the concrete layer and between adjacent decorative panels form expansion joints.

[0010] By adopting the above technical solution, when laying the floor heating pipes, the corresponding elastic filling strips are placed at the designated positions, some floor heating pipes pass through the elastic filling strips, and multiple auxiliary positioning mechanisms are placed at the positions where the elastic filling strips are not passed through by the floor heating pipes, so that the positions of the elastic filling strips are more stable. When filling concrete, the elastic filling strips can be prevented from being deviated from their positions due to the impact of concrete. The auxiliary positioning mechanisms are placed in sections, which can reduce their own impact on the function of the expansion joints, and ultimately improve the position stability of the elastic filling strips during construction, so that the formed expansion joints are more in line with the requirements of the specifications.

[0011] Optionally, the auxiliary positioning mechanism includes a base plate, a positioning plate and a pushing assembly. The base plate is placed on the insulation layer. The bottom of the elastic filling strip has a groove for accommodating the base plate. The positioning plates are vertically arranged and there are two of them. The two positioning plates are located on opposite sides of the elastic filling strip. The positioning plates are slidably connected to the base plate. There are two groups of pushing assemblies, which are located on opposite sides of the elastic filling strip. The pushing assemblies are used to push the corresponding positioning plates to slide.

[0012] By adopting the above technical solution, the auxiliary positioning mechanism is first placed in the specified position, and then the elastic filling strip is placed so that the bottom plate is located in the corresponding groove of the elastic filling strip. At this time, the two positioning plates are brought close to each other by pushing the assembly until both sides of the elastic filling strip are in contact with the positioning plates, thereby improving the efficiency of fixing the position of the elastic filling strip.

[0013] Optionally, the pushing assembly includes a hinged rod and a slider, the hinged rod is arranged at an angle, and the bottom end of the hinged rod is hinged to one end of the base plate; a sliding groove is vertically opened on the outer side of the positioning plate away from the elastic filling strip, the slider slides vertically in the sliding groove, and the top end of the hinged rod is hinged to the slider.

[0014] By adopting the above technical solution, before placing the elastic filling strip, the two positioning plates are pushed in opposite directions. After the elastic filling strip is placed between the two positioning plates, the hinged rod is pressed, and the hinged rod drives the slider to slide downward in the slide groove. At the same time, the positioning plate slides toward the elastic filling strip until it fits with the elastic filling strip, thereby improving the efficiency of fixing the position of the elastic filling strip, and being applicable to elastic filling strips of different thicknesses, thereby improving engineering applicability.

[0015] Optionally, a dovetail groove is horizontally opened on the upper surface of the bottom plate, and dovetail blocks are fixed to the bottom of the two positioning plates, and the dovetail blocks slide horizontally in the dovetail groove.

[0016] By adopting the above technical solution, when the pushing component pushes the positioning plate to move, the dovetail block slides in the dovetail groove, thereby improving the movement stability of the positioning plate.

[0017] Optionally, the side walls of the two dovetail blocks that are close to each other are both fixed with limiting rods, and when the two limiting rods abut against each other, a distance is left between the two positioning plates.

[0018] By adopting the above technical solution, the phenomenon of the two positioning plates being stuck to each other can be avoided, and it is more convenient to push the two positioning plates away from each other, thereby improving the operating efficiency.

[0019] Optionally, a receiving groove is provided at the bottom of the dovetail block, a positioning spring is fixed in the receiving groove, a top bead is fixed at the bottom of the positioning spring, and a plurality of semicircular positioning grooves are provided on the bottom wall of the dovetail groove along its own length direction. When the bottom end of the top bead is located in the positioning groove, the positioning spring is in a compressed state.

[0020] By adopting the above technical solution, when the positioning plate moves, the top beads are squeezed and inserted into the corresponding positioning grooves in sequence, which can not only position the elastic filling strips of different thicknesses, but also improve the stability of the positioning plate after the positioning plate is fixed, and try to avoid the positioning plate squeezing the elastic filling strips due to the impact of concrete, thereby improving the stability of the elastic positioning strips during construction.

[0021] Optionally, the slider is made of a magnet, the positioning plate is made of a metal material that is tightly attracted to the slider, slots are provided at both ends of the upper surface of the base plate, disassembly blocks are inserted into the slots, and the bottom end of the hinged rod is hinged to the disassembly block.

[0022] By adopting the above technical solution, after pressing the hinge rod to fix the position of the positioning plate, the disassembly block connected to the bottom end of the hinge rod is pulled out from the slot, and the slider is pulled out from the slide groove, so that the pushing component can be reused and the construction cost can be reduced.

[0023] Optionally, a pressing plate is horizontally fixed to the top end of the hinged rod.

[0024] By adopting the above technical solution, pressing the pressing plate downward can more conveniently cause the hinged rod to push the positioning plate to move, thereby improving the convenience of operation.

[0025] Optionally, the expansion joint between adjacent decorative panels is filled with sealing paste.

[0026] By adopting the above technical solution, the upper opening of the expansion joint can be sealed, thereby extending the service life of the floor heating.

[0027] Optionally, a mortar protective layer is laid between the waterproof layer and the thermal insulation layer; and a mortar bonding layer is laid between the concrete layer and the decorative board.

[0028] By adopting the above technical solution, the mortar protective layer can protect the waterproof layer. The mortar bonding layer is used to bond and fix the decorative panels to the concrete layer on the one hand, and to level the decorative panels on the other hand, making them smoother after laying.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Multiple auxiliary positioning mechanisms are placed at the locations where the elastic filling strips are not penetrated by the floor heating pipes, making the position of the elastic filling strips more stable. When filling with concrete, the elastic filling strips can be prevented from being impacted by the concrete and causing position deviation, thereby improving the position stability of the elastic filling strips during construction and making the formed expansion joints more compliant with regulatory requirements.

[0031] 2. First, push the two positioning plates in opposite directions. After the elastic filling strip is placed between the two positioning plates, the hinged rod drives the slider to slide downward in the slide slot. At the same time, the positioning plates slide toward the elastic filling strip until it fits the elastic filling strip. This improves the efficiency of fixing the elastic filling strip in place and can be used with elastic filling strips of different thicknesses, improving engineering applicability.

[0032] 3. When the positioning plate moves, the top beads are squeezed and inserted into the corresponding positioning grooves in sequence. This can not only position the elastic filling strips of different thicknesses, but also improve the stability of the positioning plate after it is fixed, and try to avoid the positioning plate squeezing the elastic filling strips due to the impact of concrete, thereby improving the stability of the elastic positioning strips during construction;

[0033] 4. After pressing the hinge rod to fix the position of the positioning plate, pull out the disassembly block connected to the bottom end of the hinge rod from the slot, and pull out the slider from the slide groove, so that the pushing component can be reused and the construction cost can be reduced.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-4 This application is described in further detail.

[0040] The embodiments of the present application disclose a floor heating floor decorative expansion joint structure.

[0041] refer to Figure 1 and Figure 2 The floor heating floor decorative expansion joint structure includes a mortar leveling layer 11, a waterproof layer 12, a mortar protective layer 13, an insulating layer 14, a floor heating pipe 15, a concrete layer 16, a mortar bonding layer 17 and a decorative panel 18, which are laid on the floor 1 from bottom to top. The floor heating pipe 15 is laid on the insulating layer 14, and the concrete layer 16 covers the floor heating pipe 15; a plurality of elastic filling strips 2 are placed on the insulating layer 14, and the lower surface of the elastic filling strip 2 is in contact with the insulating layer 14. In this embodiment, the bottom end of the elastic filling strip 2 can be extended downward to the upper surface of the floor 1, and a slot for inserting the elastic filling strip 2 is opened downward in advance on the insulating layer 14. Part of the elastic filling strip 2 is penetrated by multiple floor heating pipes 15, and the position of the elastic filling strip 2 in the concrete layer 16 and the position between the adjacent decorative panels 18 form an expansion joint 3, and the expansion joint 3 between the adjacent decorative panels 18 is filled with sealing paste 31.

[0042] refer to Figure 1 and Figure 2The insulation layer 14 is provided with a plurality of auxiliary positioning mechanisms 4 for fixing the position of the elastic filling strip 2 that is not penetrated by the floor heating pipe 15. The auxiliary positioning mechanisms 4 are arranged equidistantly along the length direction of the elastic filling strip 2; the auxiliary positioning mechanism 4 includes a bottom plate 41 placed horizontally on the insulation layer 14, two positioning plates 42 sliding on the upper surface of the bottom plate 41, and a pushing component 43 for pushing the positioning plate 42 to slide. The bottom of the elastic filling strip 2 has a groove for accommodating the bottom plate 41, and the positioning plate 42 is vertically arranged and slides horizontally.

[0043] In this embodiment, the elastic filling strip 2 is made of high-foam polyethylene foam plastic. When the floor heating pipe 15 is laid, the elastic filling strip 2 is placed in the designated position, and multiple auxiliary positioning mechanisms 4 are placed on the insulation layer 14. The elastic filling strip 2 is located between the two positioning plates 42. The two relative positioning plates 42 are moved closer to each other by pushing the component 43 until they are in contact with the side wall of the elastic filling strip 2. This can minimize the position deviation of the elastic filling strip 2 caused by the impact of concrete, thereby improving the position stability of the elastic filling strip 2 during construction, and making the formed expansion joint 3 more in line with the specification requirements.

[0044] refer to Figure 3 The side wall of the positioning plate 42 facing away from the elastic filling strip 2 is vertically provided with a sliding groove 421, and both ends of the bottom upper surface are vertically provided with slots 411. The pushing assembly 43 includes a slider 432 that slides in the sliding groove 421, a disassembly block 433 inserted in the slot 411, and a hinged rod 431 whose ends are correspondingly hinged to the slider 432 and the disassembly block 433. The slider 432 is made of a magnet, and the positioning plate 42 is made of a metal material that is tightly attracted to the slider 432. A pressing plate 4311 is horizontally fixed to the top of the hinged rod 431. Pressing the pressing plate 4311 causes the hinged rod 431 to push the positioning plate 42 toward the elastic filling strip 2, thereby improving the fixing efficiency of the elastic filling strip 2. After the positioning plate 42 moves to fit the elastic filling strip 2, the slider 432 is pulled out of the sliding groove 421, and the disassembly block 433 is pulled out of the slot 411. This allows the pushing assembly 43 to be reused, reducing construction costs.

[0045] refer to Figure 3 and Figure 4A dovetail groove 412 is horizontally formed on the upper surface of the bottom plate 41. The length of the dovetail groove 412 is perpendicular to the length of the elastic filling strip 2. A dovetail block 422 is fixed to the bottom of the positioning plate 42 and is located in the dovetail groove 412. The two dovetail blocks 422 are fixed to the opposite side walls thereof. When the two dovetail blocks 422 are in contact with each other, a distance is left between the two positioning plates 42. When the positioning plates 42 move, the dovetail blocks 422 slide in the dovetail groove 412, thereby improving the sliding stability of the positioning plates 42. The provision of the limit rods 4224 can, on the one hand, prevent the two positioning plates 42 from abutting against each other, making it more convenient to place the elastic filling strip 2 between the two positioning plates 42. On the other hand, it can prevent the elastic filling strip 2 from being pinched and flattened, thereby improving the safety and elastic stability of the elastic filling strip 2.

[0046] refer to Figure 4 The lower surface of the dovetail block 422 is vertically provided with a receiving groove 4221, in which a positioning spring 4222 is vertically fixed. A spherical top bead 4223 is fixed at the bottom end of the positioning spring 4222, which slides at the opening of the receiving groove 4221. The bottom wall of the dovetail groove 412 is equidistantly provided with a plurality of semicircular positioning grooves 413 for inserting the top bead 4223 along its own length. The positioning spring 4222 is always in a compressed state, and the top end of the top bead 4223 is always located in the receiving groove 4221. When the positioning plate 42 moves, the top bead 4223 moves with the positioning plate 42. After the positioning plate 42 has moved, the top bead 4223 is tightly pressed into the corresponding positioning groove 413, thereby improving the stability of the positioning plate 42 and minimizing the impact of concrete on the positioning plate 42 causing the elastic filling strip 2 to be squeezed, thereby improving the stability of the elastic positioning strip during construction.

[0047] The implementation principle of the floor heating floor decorative expansion joint structure of the embodiment of the present application is as follows: when laying the floor heating pipe 15, the corresponding elastic filling strip 2 is placed at the specified position, and part of the floor heating pipe 15 passes through the elastic filling strip 2, and multiple auxiliary positioning mechanisms 4 are placed at the position where the elastic filling strip 2 is not passed through by the floor heating pipe 15; the two positioning plates 42 are pushed in opposite directions in advance, and after the elastic filling strip 2 is placed between the two positioning plates 42, the pressing plate 4311 is pressed, and the hinged rod 431 drives the slider 432 to slide downward in the slide groove 421, and at the same time the positioning plate 42 slides toward the elastic filling strip 2 until it is in contact with the elastic The filling strip 2 is fitted, and at the same time, the top bead 4223 moves with the positioning plate 42. After the positioning plate 42 has moved, the top bead 4223 is tightly pressed in the corresponding positioning groove 413; after the position of the elastic filling strip 2 is fixed, the disassembly block 433 connected to the bottom end of the hinged rod 431 is pulled out from the slot 411, and the slider 432 is pulled out from the slide groove 421, so that the pushing component 43 can be reused; when filling concrete, the elastic filling strip 2 can be prevented from being deviated from its position by the impact of concrete as much as possible, thereby improving the position stability of the elastic filling strip 2 during construction, and making the formed expansion joint 3 more in line with the specification requirements.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
