Description

Technical Field

[0001] This invention relates to the technical field of temporary hardened ground paving on construction sites, and particularly to a method for constructing ground panels, a ground panel paving structure, and equipment for installing joint sealants. Background Technology

[0002] Construction projects often require the hardening of numerous temporary site roads, paved areas, parking spaces, and warehouses. Currently, the construction of temporary sites at building construction sites is typically handled by the construction company through project planning. This involves leveling the roadbed, surveying and setting out, erecting formwork, and pouring concrete. However, as the project progresses, these cast-in-place concrete surfaces need to be demolished after use, resulting in significant resource waste and the need for centralized disposal of large amounts of construction waste, which also negatively impacts the city's ecological environment.

[0003] In view of this, Chinese invention patent ZL01720185565.0 discloses a modular, recyclable prefabricated hard floor panel, comprising: a panel, a frame, ribs, lifting permeable holes, and lifting reinforcing bars; the panel includes a concrete body and a reinforcing bar skeleton, with the reinforcing bar skeleton arranged within the concrete body; the frame surrounds the panel, with its upper surface flush with the upper surface of the panel; the ribs are integrally cast with the concrete body of the panel, and the lifting permeable holes penetrate the upper and lower surfaces of the panel; the lifting reinforcing bars are located within the lifting permeable holes and embedded in the concrete body of the panel. This prefabricated hard floor panel enables modular construction in temporary building sites and can be reused, reducing wet work on construction sites and promoting green construction processes.

[0004] However, the aforementioned prefabricated hard floor panels still have the following drawbacks after being laid on the construction site:

[0005] (1) Water accumulation in the slab joints cannot be properly handled: Since the main body of the precast floor slab is made of cast concrete, even if it is laid tightly, water can still easily accumulate in the joints of the slabs. On the one hand, when construction vehicles drive over, the water will splash, which will not only affect the construction environment, but also pose a great safety hazard due to the hard impurities that accompany the splashing water; on the other hand, the water can easily corrode the main structure of the precast floor slab, causing the main structure to lose strength. In the long run, this will greatly reduce the service life and performance of the precast floor slab, making it difficult to meet the construction requirements; the vertical connection of the hoisting holes also poses a risk of water seepage.

[0006] (2) Overcoming the problem of water accumulation in the slab joints requires a large amount of materials and is costly: Due to the constraints of transportation and hoisting, the area of ​​precast floor panels cannot be designed to be too large. If the sealing strips or structural adhesives are directly used to fill the joints, the demand for sealing materials will be huge, resulting in high construction costs. Furthermore, since the sealing materials are usually difficult to reuse after the precast floor panels are removed, a large amount of construction waste will still be generated, which is also not conducive to green construction. Summary of the Invention

[0007] The first objective of this invention is to provide a method for constructing floor panels. This method involves planning several matrix units on the hard surface to be paved. Sealing elements are primarily applied to the joints within the matrix units after paving, effectively integrating multiple matrix-arranged floor panels into a single large-area panel. This saves a significant amount of sealing material. Drainage channels between the matrix units facilitate water drainage, significantly reducing construction costs and construction waste, thus ensuring the timely commencement of the main project and promoting green construction. The second objective of this invention is to protect a floor panel paving structure based on the aforementioned construction method. The third objective of this invention is to provide a joint sealing element installation device that can be used in the aforementioned floor panel construction method to further achieve cost reduction and efficiency improvement, thereby solving the technical problems described in the background section.

[0008] To achieve the above objectives, the present invention first provides a method for constructing a floor slab, the key of which includes the following steps:

[0009] S1: Excavation and compaction of the foundation trench, which serves as the base layer;

[0010] S2: Measure the base area and determine the number N of floor panels to be laid based on the base area;

[0011] S3: Divide N plots of land into K matrix units. The k-th matrix unit in the K matrix units is determined by the matrix arrangement M. k The plots consist of slabs, k = 1, 2, ..., K, N ≥ M k ≥4 and M k It is an even number;

[0012] S4: Determine the K matrix units corresponding to the K paving areas on the base layer, and excavate drainage ditches around the K paving areas respectively;

[0013] S5: Fill the drainage ditch with gravel and compact it;

[0014] S6: Measure the elevation and verify it;

[0015] S7: Lay a subbase layer on the base layer and lay out lines to level it;

[0016] S8: Transport the ground panel to the corresponding paving area and complete the paving of the corresponding matrix unit according to the paving area;

[0017] S9: Transfer the plate joint seal installation equipment to the completed matrix unit and assemble the seal on site according to the cross pattern of the matrix unit;

[0018] S10: Use the plate joint sealing installation equipment to quickly fill the sealing element into the plate joint of the corresponding matrix unit;

[0019] S11: Repeat steps S8-S10 until all K matrix units are laid and sealed in place.

[0020] Furthermore, in step S4, when K≥2, the drainage channel between the k-th matrix unit and the (k-1)-th matrix unit is shared.

[0021] Secondly, this invention also discloses a floor paving structure using the above-mentioned floor paving construction method, the key feature of which is: it includes a base layer, a subbase laid on the base layer, and N floor paving panels laid on the subbase; the N floor paving panels are divided into K matrix units; the kth matrix unit among the K matrix units is composed of M matrix arrangements. k The blocks consist of ground panels, k = 1, 2, ..., K, N ≥ M k ≥4 and M k The number is even; each of the matrix units is also filled with a sealant in its own plate joint; the sealant forms at least one drainage channel relative to any side of the matrix unit; and drainage ditches are also excavated on the base layer corresponding to each side of the matrix unit.

[0022] Furthermore, the drainage channel of the seal is stepped.

[0023] Furthermore, the sealing element is composed of a multi-layered sealing unit distributed in layers; the sealing unit includes a first-direction sealing strip and a second-direction sealing strip, and the intersection of the two is connected by tongue and groove; and the lengths of the first-direction sealing strips and the second-direction sealing strips in each layer are differentiated to form outwardly extending drainage steps.

[0024] Furthermore, the cushion layer is a sand layer, and the drainage ditch is also filled with a layer of crushed stone for support and drainage.

[0025] Finally, this invention discloses a panel joint seal installation device, specifically used in the floor panel construction method described above. Its key features include: a support structure and a hollow main body mounted on the support structure; a lead screw vertically penetrating the hollow main body; a pressing assembly connected to the lower end of the lead screw; and an internally threaded sleeve fitted onto the lead screw; the internally threaded sleeve receives rotational power through a transmission assembly, and when the internally threaded sleeve rotates, the lead screw can axially rise or fall to cooperate with the pressing assembly to achieve press-fit assembly of the panel joint seal.

[0026] Furthermore, the press-fitting assembly includes a first directional press plate and a second directional press plate, the first directional press plate and the second directional press plate being adapted to be arranged in a cross shape at the cross joints of the matrix unit.

[0027] Furthermore, the transmission assembly includes a worm gear and a worm shaft that mesh with each other. The worm gear is fixedly sleeved around the outer periphery of the internal threaded sleeve and supported above the through hole by a plane bearing. The worm shaft is connected to the wall of the transmission box via a rotating shaft.

[0028] Furthermore, one end of the rotating shaft extends out of the transmission box and is driven by a motor, and a handwheel is also connected to the end of the output shaft of the motor.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] (1) By planning several matrix units on the hard ground to be paved, the sealant is mainly applied to the joints of the matrix unit itself after paving. This is equivalent to integrating multiple matrix-arranged floor panels into a large-area floor panel. Drainage is organized between each matrix unit through drainage channels. This can save a lot of sealing material, significantly improve construction efficiency, and greatly reduce construction costs, thus promoting the timely progress of the main project. At the same time, after the main project is completed and the reusable precast floor panels are removed, the amount of sealing material used is reduced, and the amount of construction waste generated is also reduced accordingly, which is conducive to green construction and environmental protection.

[0031] (2) The number of ground panels in each matrix unit can be different, which is flexible and versatile. It can be adapted to the area and shape of the construction site to meet the diverse needs of the construction scene.

[0032] (3) The sealing element is made of flexible and deformable material, which enables the matrix unit composed of multiple floor panels to buffer the horizontal stress generated by pressure diffusion when subjected to heavy-duty engineering vehicles, thereby absorbing the deformation between the panels and preventing the floor panels from breaking; at the same time, most of the concentrated load of the wheel pressure can also be transferred to the base layer through the pad layer, thereby meeting the requirements of large-area heavy-duty construction sites.

[0033] (4) By using drainage ditches to form a drainage network around each matrix unit, water accumulation between matrix units can be prevented on the one hand, and drainage can be organized artificially on the other hand, which is conducive to the centralized diversion and reuse of water resources, thus promoting environmental protection.

[0034] (5) The installation equipment is specially designed for the characteristics of the plate joints of the matrix unit. It can assist manual labor in the rapid assembly of the plate joint seals. The installation efficiency is high, the labor intensity is low, and it is conducive to reducing the safety risks of construction personnel. It can further promote the timely progress of the main project. At the same time, since the assembly process of the seals mainly relies on the axial movement of the screw and the pressing component, the installation accuracy is higher. It can avoid the deviation caused by manual installation of the seals, so as to ensure that the anti-water accumulation effect of the plate joints meets the expectations after the sealing operation is completed.

[0035] (6) When installing equipment, the hollow main body can be erected directly above the plate seam using the support structure to quickly level the main body. During the installation of the sealing parts, the construction personnel only need to ensure that the hollow main body does not shift, which further reduces the labor intensity.

[0036] (7) The installation equipment adopts a screw and threaded sleeve meshing transmission, which can ensure the smooth lifting and lowering of the press assembly. This is conducive to the construction personnel accurately controlling the descent stroke of the press assembly, so as to avoid damage to the seal due to excessive downward pressure, and further improves the accuracy of seal installation.

[0055] Figure 1 The first embodiment of the present invention is shown, a method for constructing a floor panel, comprising the following steps:

[0056] S1: Excavation and compaction of the foundation trench, which serves as the base layer;

[0057] S2: Measure the base area and determine the number N of floor panels to be laid based on the base area;

[0058] S3: Divide N plots of land into K matrix units. The k-th matrix unit in the K matrix units is determined by the matrix arrangement M. k The plots consist of slabs, k = 1, 2, ..., K, N ≥ M k ≥4 and M k It is an even number;

[0059] S4: Determine the K matrix units corresponding to the K paving areas on the base layer, and excavate drainage ditches around the K paving areas respectively;

[0060] S5: Fill the drainage ditch with gravel and compact it;

[0061] S6: Measure the elevation and verify it;

[0062] S7: Lay a subbase layer on the base layer and lay out lines to level it;

[0063] S8: Transport the ground panel to the corresponding paving area and complete the paving of the corresponding matrix unit according to the paving area;

[0064] S9: Transfer the plate joint seal installation equipment to the completed matrix unit and assemble the seal on site according to the cross pattern of the matrix unit;

[0065] S10: Use the plate joint sealing installation equipment to quickly fill the sealing element into the plate joint of the corresponding matrix unit;

[0066] S11: Repeat steps S8-S10 until all K matrix units are laid and sealed in place.

[0067] Preferably, in step S4, when K≥2, the drainage channel between the k-th matrix unit and the (k-1)-th matrix unit is shared.

[0068] Please see Figures 2 to 5 As shown, the floor paving structure 100 constructed using the floor paving construction method described above includes a base layer 101, a subbase 102 laid on the base layer 101, and N floor paving panels 103 laid on the subbase 102; the N floor paving panels 103 are divided into K matrix units 4; the k-th matrix unit 104 among the K matrix units 104 is composed of M matrix units arranged in a matrix. k The block consists of 3 ground panels, k = 1, 2, ..., K, N ≥ M k ≥4 and M k The number is even; each of the matrix units 104 is also filled with a seal 105 in its own plate joint; the seal 105 forms at least one drainage channel 106 relative to any side of the matrix unit 104; and drainage ditches 107 are also excavated on the base layer 101 corresponding to each side of the matrix unit 104.

[0069] like Figures 2 to 4As shown, in this embodiment, n=16, k=4, and the construction site is paved with 16 floor panels 103 arranged in a 4×4 pattern. These 16 floor panels 103 are divided into 4 matrix units 104. In each matrix unit 104, the floor panels 203 are arranged in a 2×2 pattern. The joint seals 105 are arranged in a cross shape. A drainage channel 106 is provided on each of the four edges of the matrix unit 104, and the drainage channels 106 are connected to the corresponding drainage ditches 107 on the edges of the matrix unit 104. In other embodiments, for example, the construction site is paved with 20 floor panels 103 arranged in a 4×5 pattern. These 20 floor panels 103 are planned into 4 matrix units 104, where 2 matrix units 104 can be arranged in a 2×2 pattern, and the other 2 matrix units 104 can be arranged in a 2×3 pattern. In a 2×2 matrix unit 104, the joint sealant 105 adopts a cross-shaped arrangement, with one drainage channel 106 connecting to the corresponding drainage ditch 107 on each of the four sides of the matrix unit 104. In a 2×3 matrix unit 104, the joint sealant 105 adopts an I-shaped arrangement, with two drainage channels 106 connecting to the corresponding long sides of the matrix unit 104, and one drainage channel 106 connecting to the corresponding short side of the matrix unit 104. In short, the number and arrangement of the floor panels 103 in each matrix unit 104 do not need to be the same. Similarly, the cross-shaped arrangement of the joint sealant 105 filling the joints of different matrix units 104 is not fixed and can be adaptively adjusted according to the actual application scenario. It should be explained that the matrix arrangement mentioned in this embodiment is i×j, where i is the number of floor panels in a row and j is the number of floor panels in a column; i and j ≥ 2.

[0070] In order to ensure that each drainage channel 107 is properly used under the premise of forming a drainage network, the drainage channels 107 of two adjacent matrix units 104 are shared.

[0071] As described above, the seal 105 is adapted to have its own plate seams of the matrix unit 104 arranged in a cross shape. In specific implementation, the drainage channel 106 of the seal 105 is stepped. Figure 6As can be seen, in a preferred embodiment, the sealing element 105 is composed of a multi-layered sealing unit with hierarchical distribution. Each sealing unit includes a first-direction sealing strip 110 and a second-direction sealing strip 111, which are connected at their intersection using a tongue-and-groove joint. Furthermore, the lengths of each layer of the first-direction sealing strip 110 and the second-direction sealing strip 111 are differentiated to form outwardly extending drainage steps. The hierarchical distribution of sealing units in the sealing element 105 facilitates layered installation by construction personnel; that is, the upper sealing unit is installed after the lower sealing unit is completed. Simultaneously, the tongue-and-groove connection of the first-direction sealing strip 110 and the second-direction sealing strip 111 allows them to intersect on the same plane, improving the sealing effect and further facilitating construction. In addition, the drainage steps formed by the differentiated lengths of the first and second sealing strips guide water flow towards the corresponding drainage channel 107, thus cooperating with the drainage channel 107 to achieve the technical effect of organized drainage.

[0072] Reference Figure 2 and Figure 3 To meet heavy load requirements and achieve drainage, the cushion layer 102 is a sand layer, and the drainage ditch 107 is also filled with a gravel layer 112 for support and drainage. It can be understood that, in order to achieve centralized treatment and recycling of water resources, the surface of the drainage ditch 107 can be sloped.

[0073] Considering that after the matrix unit 104 is planned, the construction site will still need to lay scattered floor panels 103. In order to avoid water accumulation in the gaps between these scattered floor panels 103, the gaps between the remaining floor panels 103 (excluding the K matrix units 104) of the N floor panels 103 are sealed by filling with sealing strips or filling with structural adhesive.

[0074] Please see Figure 6 This embodiment also discloses a panel joint sealing component installation device 200 specifically used in the aforementioned floor panel construction method, including a support structure 201 and a hollow body 202 disposed on the support structure 201; a lead screw 203 is vertically inserted through the hollow body 202; a press-fitting assembly 204 is connected to the lower end of the lead screw 203; an internally threaded sleeve 205 is also fitted onto the lead screw 203; the internally threaded sleeve 205 receives rotational power through a transmission assembly 206, and when the internally threaded sleeve 205 rotates, the lead screw 203 can rise or fall axially to cooperate with the press-fitting assembly 204 to achieve press-fitting assembly of the sealing component 105.

[0075] like Figure 7 and Figure 8As shown, in specific implementation, to facilitate the storage and transportation of the installed equipment, the support structure 201 includes several support rods 207 evenly distributed around the axis of the hollow main body 202. The first end of each support rod 207 is hinged to the hollow main body 202 via a first lug 208. A connecting rod 209 is also hinged to each support rod 207, and the end of each connecting rod 209 is hinged to the hollow main body 202 via a second lug 210. Preferably, to facilitate the installation of the seal 105 and restrict the position of the hollow main body 202, footboards 220 can be provided at the ends of at least two opposite support rods 207. During operation, the installer only needs to step on the two opposite footboards 220 to fix the support structure 201, thereby restricting the position of the hollow main body 202.

[0076] from Figure 8 and Figure 10 As can be seen, in this embodiment, the pressing assembly 204 includes a first directional pressing plate 211 and a second directional pressing plate 212. The first directional pressing plate 211 and the second directional pressing plate 212 can be adapted to be arranged in a cross shape at the cross joints of the floor panel 103. Specifically, the first directional pressing plate 211 is fixed to the lower end of the lead screw 203, and the second directional pressing plate 212 is detachably connected to the first directional pressing plate 211. Further, the second directional pressing plate 212 and the first directional pressing plate 211 are connected by a tongue and groove joint (see [reference]). Figure 12 The advantage of this design is that when assembling the sealant 105 between the straight seams of the two floor panels 103 in the matrix unit 104, only the first direction pressure plate 211 needs to be retained. However, when assembling the sealant 105 between the intersecting seams formed at the centers of the four floor panels 103, the second direction pressure plate 212 can be installed on the first direction pressure plate 211, thus matching the intersection of the "+" shaped seams. This design offers high flexibility and can fully adapt to diverse construction needs. In other embodiments, the first direction pressure plate 211 and the second direction pressure plate 212 can also adopt a scissor-hinged connection. That is, when assembling the straight seams between the two floor panels 103, the first direction pressure plate 211 and the second direction pressure plate 212 can be closed, making their structure approach a straight line. Similarly, when assembling the sealant 105 at the intersecting seams, the first direction pressure plate 211 and the second direction pressure plate 212 can be opened, forming a "+" shaped structure.

[0077] Considering the need for replacement of the seal 105 after long-term use, and given that most sealing materials on the market are made of plastic, both the first directional pressure plate 211 and the second directional pressure plate 212 are made of thermally conductive metal, and an electric heating mechanism is integrated inside the first directional pressure plate 211 and / or the second directional pressure plate 212. Utilizing the heat-melting effect, the first directional pressure plate 211 and the second directional pressure plate 212 can be embedded into the seal 105 that needs replacement. After cooling, the seal 105 can be pulled out using the lead screw 203. This method offers good performance and has broad application prospects. It is understood that because the second directional pressure plate 212 has a detachable structure, if an electric heating mechanism is to be integrated into the second directional pressure plate 212, a separate power connection port needs to be configured on the second directional pressure plate 212.

[0078] like Figures 8 to 11 As shown, a transmission box 213 is provided on the hollow main body 202. The bottom of the transmission box 213 has a through hole 214 for the lead screw 203 to pass through non-contactly. The transmission assembly 206 is disposed inside the transmission box 213. The transmission assembly 206 includes a meshing worm gear 215 and a worm 216. The worm gear 215 is fixedly sleeved around the outer periphery of the internal threaded sleeve 205 and supported above the through hole 214 by a plane bearing 217. The worm 216 is connected to the box wall of the transmission box 213 via a rotating shaft. When the motor 218 is turned on, it can drive the worm 216 to rotate via the rotating shaft. The worm 216 then drives the internal threaded sleeve 205 to rotate via the meshing worm gear 215. At this time, the lead screw 203 can move axially. By controlling the direction of the motor 218, the lead screw 203 can be raised or lowered. Preferably, to avoid the constraints of mains power, a battery can be installed in a suitable location on the equipment. Meanwhile, to facilitate the control of the motor 218 and the heating mechanism, a lifting switch connected to the control circuit of the motor 218 and a heating switch connected to the control circuit of the heating mechanism can also be provided. It is worth mentioning that a handwheel 219 is also connected to the end of the output shaft of the motor 218. In the event of a power outage, the construction personnel can still perform the installation of the seal 105 by operating the handwheel 219. In a preferred embodiment, the first directional pressure plate 211 is connected to the lead screw 203 via a pressure sensor. The pressure sensor is connected to the control circuit of the motor 218, enabling the pressure sensor to monitor the downward pressure applied to the seal 105 by the pressing assembly 204. When the downward pressure reaches a predetermined threshold, the motor 218 can be paused, thereby preventing excessive downward pressure from damaging the seal 105.

[0079] Finally, it should be noted that, based on the sealing structure described above, the installation method for the mounting device 200 is as follows: the upper sealing unit is installed after the lower sealing unit is installed (refer to...). Figure 13 ).

[0080] In summary, by planning several matrix units 104 on the hard ground to be paved, and using the sealing element 105 mainly in the joints of the matrix unit 104 after paving, it is equivalent to integrating multiple matrix-arranged floor panels 103 into a large-area floor panel 103. Drainage is organized between each matrix unit 104 through drainage channels 107. This can save a lot of sealing material, significantly improve construction efficiency, and greatly reduce construction costs, thereby promoting the timely progress of the main project. Meanwhile, after the main project is completed and the reusable precast floor panels 103 are removed, the amount of sealing material used is reduced, thus reducing construction waste and promoting green construction and environmental protection. The number of floor panels 103 in each matrix unit 104 can be different, offering good flexibility and versatility. It can be adapted to the area and shape of the construction site to meet the diverse needs of different construction scenarios. The sealing element 105 is made of a flexible and deformable material, which allows the matrix unit 104 composed of multiple floor panels 103 to buffer the horizontal stress generated by pressure diffusion when subjected to heavy-duty construction vehicles, thereby absorbing the deformation between the panels and preventing damage to the floor panels 103. At the same time, most of the concentrated load of the wheel pressure can also be transferred to the base layer 101 through the pad layer 102, thus meeting the requirements of large-area heavy-duty construction sites. The drainage network is formed around each matrix unit 104 using drainage ditches 107. This not only prevents water accumulation between the matrix units 104, but also enables artificial drainage, which is conducive to the centralized diversion and reuse of water resources, thus promoting environmental protection. The installation equipment 200, specially designed for the characteristics of the joints in the matrix unit 104, can assist in the rapid assembly of the joint seals 105 manually. This results in high installation efficiency, low labor intensity, and reduced safety risks for construction workers, further promoting the timely progress of the main project. Furthermore, since the assembly of the seals 105 primarily relies on the axial movement of the lead screw 203 in conjunction with the pressing assembly 204, the installation precision is higher, avoiding deviations that occur during manual installation of the seals 105 and ensuring effective water prevention in the joints after sealing. As expected; during construction, the hollow main body 202 can be quickly leveled by using the support structure 201 to place it directly above the plate seam. During the installation of the seal 105, the construction personnel only need to ensure that the hollow main body 202 does not shift, which further reduces the labor intensity; the use of the lead screw 203 and the threaded sleeve for meshing transmission can ensure the smooth lifting and lowering of the press assembly 204, which is conducive to the construction personnel accurately controlling the descent stroke of the press assembly 204, so as to avoid damage to the seal 105 due to excessive downward pressure, and further improve the installation accuracy of the seal 105.
