Description

Technical Field

[0001] This invention belongs to the field of composite slab installation, specifically to auxiliary equipment and construction methods for prefabricated composite slab installation. Background Technology

[0002] Prefabricated composite slabs are prefabricated components composed of multiple layers of materials, typically consisting of two outer slabs and an intermediate infill material. This structure gives the composite slab excellent strength, stiffness, and durability. The construction of prefabricated composite slabs can be designed and customized according to specific application requirements. The outer slabs are usually made of metals such as aluminum and steel, or composite materials such as glass fiber reinforced plastics and carbon fiber reinforced plastics, to provide protection and structural support. The intermediate infill material can be polystyrene board, foam plastics, lightweight concrete, etc., to increase thermal insulation performance, reduce weight, or provide additional strength. Prefabricated composite slabs have several key advantages: rapid installation, lightweight and high strength, good insulation performance, and versatility. Prefabricated composite slabs are widely used in the construction industry, especially in rapid construction and modern building projects.

[0003] Figure 8 This is a schematic diagram of a composite slab. Of its two outer slabs, one is defined as the top slab, and the other as the bottom slab. Reinforcing bars A1 are arranged transversely on the top slab. Longitudinally, several inserts A2 are evenly distributed transversely at one end of the composite slab, and slots A3, corresponding to the inserts A2, are provided at the other end of the composite slab. During installation, multiple composite slabs need to be assembled. During assembly, the inserts A2 of two adjacent composite slabs are inserted into the slots A3 at the other end, and adhesive is injected into the joint between adjacent composite slabs.

[0004] Currently, when installing composite slabs at heights, a crane is first needed to suspend the slabs to be installed to the designated position. Then, workers work together to stabilize and assemble the slabs. The assembly process involves inserting the slab into the slots and inserts of the existing slab, then injecting adhesive into the joint. This assembly process is also completed by workers. This construction method has the following drawbacks: First, the manual alignment and assembly of the slabs by workers poses safety hazards during operation; second, the manually assembled slabs may have slight deviations, potentially affecting the overall integrity of the slabs. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary equipment and construction method for the installation of prefabricated composite slabs, which can replace manual straightening for the docking of composite slabs, improving safety while ensuring docking quality.

[0006] The technical solution adopted in this invention is: an auxiliary equipment for the installation of prefabricated composite slabs, including a traction device, a bottom guide bracket, a gap filling and adhesion mechanism, and a positioning outer plate that is laterally fastened to the end of the composite slab;

[0007] The bottom guide bracket has two sets and is symmetrically arranged at the left and right ends of the positioning outer plate. The bottom guide bracket includes an electric push rod, a mounting plate and a support plate. The support plate extends longitudinally and is installed on the positioning outer plate via an electric push rod that extends laterally.

[0008] The gap filling and adhesion mechanism includes a detection-type spraying assembly and a feeding assembly that provides filler to the detection-type spraying assembly, wherein the detection-type spraying assembly is disposed on the front side of the positioning outer plate;

[0009] The traction device is provided in two sets and is symmetrically installed on the left and right ends of the positioning outer plate.

[0010] Furthermore, it also includes a guide ramp, which is installed at an angle on the top of the front end of the positioning outer plate and has several sets of balls embedded in its working surface.

[0011] Furthermore, the positioning outer plate is provided with a locking structure for clamping the end of the composite plate. The locking structure includes a motor, a screw, a slider, and a clamping plate. The bottom of the positioning outer plate is machined with a clamping opening, and two sets of sliding grooves are symmetrically opened on the side. The motor is installed at the outer end of the sliding groove, and its power output end is connected to the screw. The screw is rotatably disposed in the sliding groove and its threads pass through the slider. The slider is slidably disposed in the sliding groove, and its lower end is connected to the clamping plate.

[0012] Furthermore, the clamping plate is arc-shaped and has a notch machined on its inner side, and the end face of the notch is semi-circular.

[0013] Furthermore, the traction device includes an outer cover, a second motor, a winding reel, and a traction rope. The outer cover is fixed to the top of the positioning outer plate, the second motor is built into the outer cover and its power output end is connected to the winding reel, and the inner end of the traction rope is connected to the winding reel.

[0014] Furthermore, the traction rope includes a main rope and auxiliary ropes disposed at the outer end of the main rope, with one main rope corresponding to two auxiliary ropes.

[0015] Furthermore, the support plate includes a plate body one and a plate body two, with the plate body two being horizontally disposed inside the plate body one;

[0016] The first plate is inclined outwards from the bottom to the top in a vertical direction, and the second plate is connected to the bottom of the first plate. The guide adjustment structure includes several sets of vertically distributed rollers that are rotatably arranged on the inner side of the first plate along its longitudinal direction.

[0017] Furthermore, the feeding assembly of the gap filling adhesion mechanism includes a storage container, a pump body, a conveying pipe, and a guide pipe. The storage container is mounted on the positioning outer plate and connected to the pump body through a pipe. The pump body is connected to the guide pipe through the conveying pipe. The detection-type spraying assembly is vertically mounted at the bottom of the guide pipe.

[0018] Furthermore, the detection-type spraying assembly includes a guide plate, a stacked plate, a first conductive head, and a second conductive head. The guide plate is divided into two groups and connected to a flexible tube at its upper end. The flexible tube is connected to the guide tube. The stacked plate is disposed between the two groups of guide plates. The first conductive head and the second conductive head are respectively disposed at both ends of the stacked plate and connected to external cables. The cables are connected to a controller. The upper end of the guide plate is funnel-shaped and the bottom is blade-shaped. The inner side of the guide plate is provided with a liquid guiding cavity and several discharge holes are evenly opened on the edge.

[0019] The construction method using prefabricated composite slab installation auxiliary equipment involves two composite slabs to be spliced, one of which is an already installed composite slab used for installing the positioning outer panel, and the other is a composite slab to be installed.

[0020] Step 1: Install and fix the pre-assembled composite plate, and install the positioning outer plate at the end of the pre-assembled composite plate; place the detection spraying assembly longitudinally on the top surface of the pre-assembled composite plate, with the middle of the stacked sheet aligned with the front end of the pre-assembled composite plate.

[0021] Step 2: Suspend the stacked panels to be installed to the designated position and lower them to a reachable height;

[0022] Step 3: Secure the auxiliary rope to the steel reinforcement support at the end of the composite slab to be installed;

[0023] Step 4: The traction device pulls the stacked plate to be installed forward and lowers it onto the support plate at the same time;

[0024] Step 5: The traction device continues to pull, and the laminated sheets are squeezed. When the first conductive head and the second conductive head come into contact, the controller controls the pump to draw the adhesive into the guide tube, and fills and reinforces the gaps of the laminated sheets through the guide plate.

[0025] Step 6: The electric push rod pushes the support plate to unfold and detach it from the installed stacked plate.

[0026] The beneficial effects of this invention are as follows: This invention, by fastening the positioning outer plate to the end of the installed composite plate, provides a positioning base point for traction. Two sets of bottom guide brackets, symmetrically arranged at the left and right ends of the positioning outer plate, support the composite plate to be installed. Under traction, the composite plate to be installed is pulled longitudinally along the support brackets towards the installed composite plate. Furthermore, the electric push rod of the bottom guide bracket extends and retracts laterally, causing the connected support brackets to move laterally, thereby adjusting the lateral spacing between the support brackets at the left and right ends of the positioning outer plate to accommodate the width of the composite plate to be installed, thus satisfying the docking installation of composite plates of various specifications. Under the combined action of the positioning outer plate, the bottom guide bracket, and the traction device, the composite plate to be installed is pulled and assembled with the installed composite plate, avoiding the drawbacks of traditional crane hoisting requiring workers to straighten and install, improving safety while ensuring docking quality.

[0027] The adhesive is filled into the gaps by the gap filling and adhesion mechanism, which can be used to reinforce the joints of the composite panels. This avoids the need for workers to apply the adhesive by hand with a glue gun, thus saving labor.

[0028] The gap-filling adhesive mechanism, with its guide plate, laminated sheets, conductive head one, and conductive head two, allows the laminated sheet 28 to be compressed as the laminated plate to be installed approaches the already installed laminated plate. The gap between the laminated halves is monitored by the contact of conductive head one 29 and conductive head two 30. The controller 32 then controls the pump 14 to extract the adhesive. The adhesive flows down along the gaps in the laminated plates and adheres, completing the reinforcement treatment at the joint of the two sets of laminated plates. The mechanism automatically controls the gap width between the laminated plates, achieving higher precision compared to manual visual observation and ensuring consistent gap widths. Furthermore, it automates the adhesive coating process. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0039] In this invention, the terms "longitudinal," "lateral," "vertical," "upper," "front," "rear," "vertical," "horizontal," "top," and "bottom," etc., indicate the orientation or positional relationship based on the appendix. Figure 2 The orientation or positional relationship shown is for the purpose of describing the invention only, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0040] Auxiliary equipment for the installation and construction of prefabricated composite slabs, such as Figure 1 , Figure 2 or Figure 4 As shown, it includes a traction device, a bottom guide bracket, a gap filling and adhesion mechanism, and a positioning outer plate 1 that is laterally fastened to the end of the composite plate. The positioning outer plate 1 is fastened to the end of the installed composite plate and serves to provide a positioning base point for traction.

[0041] In order to detachably fix the positioning outer plate 1 to the end of the installed composite plate, the positioning outer plate 1 is provided with a locking structure for clamping to the end of the composite plate, such as... Figure 4 As shown, the locking structure includes a motor 2, a screw 3, a slider 4, and a clamping plate 5; the bottom of the positioning outer plate 1 is machined with a clamping opening 7 and two sets of sliding grooves 8 are symmetrically opened on the side. The motor 2 is installed at the outer end of the sliding groove 8 and its power output end is connected to the screw 3. The screw 3 is rotatably disposed in the sliding groove 8 and its threads pass through the slider 4. The slider 4 is slidably disposed in the sliding groove 8 and its lower end is connected to the clamping plate 5.

[0042] During operation, the positioning outer plate 1 is positioned at the end of the composite plate. Motor 2 drives the screw 3 to rotate, causing the slider 4 to move the clamping plate 5 laterally, thus clamping and fixing the reinforcing bar supports on the surface of the composite plate with the two sets of clamping plates 5. The inner side of the clamping plate 5 is machined with a notch 26, the end face of which is semi-circular. The notch 26 on the clamping plate 5 can accommodate the reinforcing bars of the reinforcing bar supports, ensuring clamping stability.

[0043] The bottom guide bracket has two sets, symmetrically arranged at the left and right ends of the positioning outer plate 1, such as... Figure 1 and Figure 3 As shown, the bottom guide bracket includes an electric push rod 10, a mounting plate 11, and a support plate 12. The support plate 12 extends longitudinally and is mounted on the positioning outer plate 1 via the laterally extending electric push rod 10. The support plate 12 supports the composite slab to be installed, allowing the composite slab to be installed to be pulled closer to the already installed composite slab along the longitudinal direction of the support plate 12 under traction. The electric push rod 10 extends laterally, enabling it to move the connected support plate 12 laterally, thereby adjusting the lateral spacing of the support plates 12 located at the left and right ends of the positioning outer plate 1 to accommodate the width of the composite slab to be installed, thus satisfying the butt joint installation of composite slabs of various specifications.

[0044] The gap-filling and adhesion mechanism includes a detection-type spraying assembly 17 and a supply assembly for providing filler to the detection-type spraying assembly 17. The detection-type spraying assembly 17 is positioned on the front side of the positioning outer plate 1. The function of the gap-filling and adhesion mechanism is to fill the joint gap between the laminated plates with adhesive, thereby reinforcing the connection between the laminated plates. The supply assembly stores the adhesive and delivers it to the detection-type spraying assembly 17, which then sprays the adhesive into the gap. The gap-filling and adhesion mechanism eliminates the need for workers to manually apply the adhesive using a glue gun, saving labor.

[0045] The traction device has two sets, which are symmetrically installed at the left and right ends of the positioning outer plate 1. The traction device provides traction force, and the two sets of traction devices pull laterally on the left and right sides of the composite plate to be installed, which helps to ensure the stability of traction.

[0046] The traction device can be a hydraulic cylinder, etc. In this embodiment, for example... Figure 7As shown, the traction device includes an outer cover 18, a second motor 19, a winding reel 20, and a traction rope. The outer cover 18 is fixed to the top of the positioning outer plate 1. The second motor 19 is built into the outer cover 18, and its power output end is connected to the winding reel 20. The inner end of the traction rope is connected to the winding reel 20. This structure, with its traction rope, facilitates connection with the stacked plates, and after traction is completed, it is easy to disassemble the traction rope from the stacked plates for traction of the next stacked plate. Traction is achieved by winding the traction rope to the winding reel 20, which does not occupy space. In use, only the winding of the traction rope requires power from the second motor 19, while releasing the traction rope does not require power from the second motor 19, thus saving energy.

[0047] To facilitate the binding of the traction rope to the composite plate to be installed, preferably, the traction rope includes a main rope 21 and an auxiliary rope 22 disposed at the outer end of the main rope 21, with one main rope 21 corresponding to two auxiliary ropes 22.

[0048] It also includes a guide ramp 6, which is installed at an angle on the top of the front end of the positioning outer plate 1, and its working surface is embedded with several sets of balls 9. A through hole is provided on the guide ramp 6, through which the main rope 21 of the traction rope passes, with one end fixed to the take-up reel 20 and the other end connected to the auxiliary rope 22. During the process of the traction rope pulling the stacked plate, the guide ramp 6 guides the stacked plate.

[0049] The support plate 12 can be a flat plate or an L-shaped steel beam. In this embodiment, the support plate 12 includes a first plate 23 and a second plate 24, with the second plate 24 horizontally positioned inside the first plate 23. Since there are two sets of bottom guide brackets, there are two support plates 12 and correspondingly two first plates 23. The area between the first plates 23 of the two support plates 12 is the inner side of the first plate 23. The first plate 23 is vertically inclined outwards from the bottom to the top, and the second plate 24 is connected to the bottom of the first plate 23. The guiding adjustment structure includes several sets of vertically distributed rollers 25 rotatably arranged along the inner side of the first plate 23. Through the gradually outward-inclined first plate 23 and the rollers 25, during the descent of the composite plate, the rollers 25 guide the composite plate inwards, ensuring that the composite plate is completely placed on the second plate 24, thereby achieving the purpose of position adjustment.

[0050] The feeding assembly can be placed independently of the positioning outer plate 1 on the ground or workbench, supplying material to the detection-type spraying assembly 17 via pipes. To achieve integration, avoid occupying extra space, and facilitate use and management, the feeding assembly of the gap-filling adhesive mechanism includes a storage container 13, a pump body 14, a conveying pipe 15, and a guide pipe 16. The storage container 13 is mounted on the positioning outer plate 1 and connected to the pump body 14 via pipes. The pump body 14 is connected to the guide pipe 16 via the conveying pipe 15. The detection-type spraying assembly 17 is vertically mounted at the bottom of the guide pipe 16. The adhesive in the storage container 13 is transferred to the guide pipe 16 via the pump body 14 and the conveying pipe 15, and then guided into the detection-type spraying assembly 17 for coating.

[0051] The detection-type spraying assembly 17 can be a spray gun or the like that moves back and forth laterally. In this embodiment, for example... Figure 5 As shown, the detection-type spraying assembly 17 includes a guide plate 27, a stacked plate 28, a first conductive head 29, and a second conductive head 30. The guide plate 27 is divided into two groups and connected to a flexible hose 31 at its upper end. The flexible hose 31 is connected to the guide tube 16. The stacked plate 28 is disposed between the two groups of guide plates 27. The first conductive head 29 and the second conductive head 30 are respectively disposed at both ends of the stacked plate 28 and connected to external cables. The cables are connected to a controller 32. The upper end of the guide plate 27 is funnel-shaped and the bottom is blade-shaped. The inner side of the guide plate 27 is provided with a liquid guiding cavity 33 and several discharge holes 34 are evenly opened on the edge.

[0052] At work, such as Figure 6 As shown, the bottom end of the guide plate 27, where the discharge hole 34 is located, extends into the gap between the laminated plate B to be installed and the already installed laminated plate A. During the process of the laminated plate B moving towards the already installed laminated plate A, the laminated sheet 28 is compressed, causing the gap between the first conductive head 29 and the second conductive head 30 to narrow. When the first conductive head 29 and the second conductive head 30 come into contact, it indicates that the gap has reached the set value. The controller 32 then controls the pump body 14 to draw the adhesive into the guide pipe 16. The adhesive in the guide pipe 16 is transported to the guide plate 27 via the hose 31 and discharged through the discharge hole 34 at the bottom of the guide plate 27. The adhesive flows down along the gap of the laminated plates and adheres, completing the reinforcement treatment at the joint of the two sets of laminated plates. Because the lower end of the guide plate 27 extends slightly into the gap, it is also convenient to disassemble and remove the guide plate 27. After the auxiliary installation is completed, the support plate 12 can be unfolded and detached from the bottom of the laminated plate by pushing the electric push rod 10. This setup automatically controls the gap width between the laminated panels, offering higher precision compared to manual visual inspection and ensuring consistent gap widths. It also automates the adhesive application process.

[0053] The construction method using prefabricated composite slab installation auxiliary equipment involves two composite slabs to be spliced, one of which is the pre-installed composite slab A used to install the positioning outer panel 1, and the other is the composite slab B to be installed.

[0054] Step 1: Install and fix the pre-assembled composite plate A, and install the positioning outer plate 1 at the end of the pre-assembled composite plate A; place the detection spraying assembly 17 longitudinally along the top surface of the pre-assembled composite plate A, and align the middle of the stacked sheet 28 with the front end of the pre-assembled composite plate A.

[0055] Step 2: Suspend the composite panel B to be installed to the designated position and lower it to a height that can be grasped;

[0056] Step 3: Tie auxiliary rope 22 to the steel bar support at the end of the composite slab B to be installed;

[0057] Step 4: The traction device pulls the stacked plate B to be installed forward and lowers it onto the support plate 12 at the same time.

[0058] Step 5: The traction device continues to pull, and the laminated sheet 28 is squeezed. When the first conductive head 29 and the second conductive head 30 come into contact, the controller 32 controls the pump body 14 to draw the adhesive into the guide tube 16, and fills and reinforces the gaps of the laminated sheet through the guide plate 27.

[0059] Step 6: The electric push rod 10 pushes the support plate 12 to unfold and detach from the installed stacked plate A.

[0060] The construction method using prefabricated composite slab installation auxiliary equipment enables the traction movement, position adjustment, and gap filling and reinforcement of the composite slabs, greatly improving the automation level and assembly effect of the composite slabs during the assembly process.
