Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building materials, and in particular to an assembled composite plate supporting structure. Background Art
[0002] The composite slab is composed of a prefabricated base plate, a plate seam and a cast-in-place layer. It is a floor slab composed of a prefabricated plate and cast-in-place reinforced concrete. During the construction process, the composite slab is hoisted into place and the plate-belt beam reinforcement is tied. At this stage, after the reinforcement is tied, it is necessary to use a sponge rubber strip to seal the plate-belt bottom template and the bottom of the composite slab to prevent leakage of cast-in-place concrete construction. However, sealing the bottom of the slab with only the help of sponge rubber strips can only play a simple shielding role. Due to the heavy weight of the plate-belt beam reinforcement, after the concrete pouring is completed and the template is removed, it is found that there are still misalignment and leakage. The actual sealing effect is not good, and a large amount of manpower is required for grinding. Manual grinding not only generates a large amount of dust, thereby causing harm to the staff and the construction environment, but also consumes a lot of construction costs. Therefore, the present invention provides an assembled composite slab support structure to meet the needs. Summary of the invention

[0006] Optionally, the support assembly has three usage states corresponding to: prefabricated slab hoisting state, slab-belt-beam reinforcement and binding reinforcement fixing state, and assembled composite slab concrete pouring state.
[0007] Optionally, in the hoisting state of the prefabricated panels: the supporting assembly includes a second limiting plate inserted into the top of the template, the second limiting plate is inserted into the gap between the two prefabricated panels, both ends of the second limiting plate are slidably connected with L-shaped telescopic plates, the top of the second limiting plate is screwed with a connecting rod, and the first limiting plate is screwed on the outer wall of the connecting rod.
[0008] Optionally, guide parts are installed at both ends of the first limiting plate, and the guide parts have an outward inclined angle. The first limiting plate is symmetrically provided with a recessed part and an anti-slip part, and the recessed part has a downwardly recessed arc-shaped contour, and the anti-slip part has anti-slip grooves on its surface.
[0009] Optionally, the top and the bottom of the second limiting plate are fixedly connected to a mounting seat, a thread is provided in the mounting seat, and the connecting rod and the second limiting plate are fixed to each other via the mounting seat.
[0010] Optionally, one end of the L-shaped telescopic plate close to the second limiting plate is fixedly connected to a first mounting plate, one end of the first mounting plate is fixedly connected to an elastic plate, and one end of the elastic plate away from the first mounting plate is fixedly connected to a second mounting plate.

[0012] Optionally, when the plate strip beam reinforcement and the tied reinforcement are in a fixed state: the top of the recessed portion conflicts with the bottom of the plate strip beam reinforcement, and there is a gap between the bottom of the plate strip beam reinforcement and the top of the formwork.
[0013] Optionally, in the concrete pouring state of the prefabricated composite slab: the bottom of the L-shaped telescopic plate abuts against the top of the prefabricated slab, the connecting rod passes through the avoidance hole and extends to the bottom of the formwork, the first limit plate is screwed on the outer wall of the connecting rod, and the top of the first limit plate abuts against the bottom of the formwork.
[0014] Optionally, the size of the mounting seat is matched with the size of the avoidance hole, the connecting rod is screwed at the middle position of the first limiting plate, and the middle position of the first limiting plate is thickened.
[0015] Compared with the prior art, the present invention has at least the following beneficial effects:
[0016] In the above scheme, by setting up the support assembly, not only can the sealing between the precast panel and the formwork be improved, so that during the concrete pouring process of the composite panel, the concrete will not leak out from the gap between the precast panel and the formwork, thereby improving the concrete pouring effect and saving the manpower and material resources consumed by additional grinding. Secondly, the setting of the support assembly can also assist the operator in hoisting the precast panel and improve the efficiency of hoisting the precast panel onto the formwork. In addition, the support assembly can assist the operator in tying the steel bars of the plate-belt beam and improve the efficiency of tying the steel bars of the plate-belt beam.
[0017] When the support assembly is in the prefabricated board hoisting state, the guide part can be used for auxiliary guidance during the displacement of the prefabricated board toward the template. At this time, the support assembly is installed at the four corners of the prefabricated board hoisting position to fully guide the prefabricated board. With the auxiliary guiding effect of the guide part, not only can the efficiency of the operator in hoisting the prefabricated board be improved, but also the placement position of the prefabricated board can be more accurate during the hoisting process.
[0018] When the support assembly is in a fixed state of the slab-belt beam reinforcement and the binding reinforcement, the slab-belt beam reinforcement will be lifted a distance from the bottom of the formwork under the support of the support assembly, so that its bottom and the top of the formwork are separated from each other and there is a certain distance between them. After the slab-belt beam reinforcement is lifted, the construction workers have more space to wind the binding reinforcement, and are not easily injured by the reinforcement extending from the prefabricated plate during the winding process, thereby improving the efficiency of the slab-belt beam reinforcement binding and improving the safety of the construction workers. In addition, since the recessed portion has a downwardly recessed arc-shaped contour, when the slab-belt beam reinforcement is placed on the surface of the first limiting plate, the arc-shaped contour of the recessed portion can be used to limit the slab-belt beam reinforcement, thereby improving the stability and safety of the slab-belt beam reinforcement binding process.
[0019] When the support assembly is in the concrete pouring state of the prefabricated composite slab, the construction workers first place the second limit plate on the top of the prefabricated slab, and then screw the first limit plate on the bottom of the formwork. Under the action of the connecting rod, the first limit plate and the second limit plate will produce a pulling effect between the prefabricated slab and the formwork, thereby improving the sealing between the prefabricated slab and the formwork and preventing side leakage of concrete during the pouring process.

[0043] like Figures 1 to 11As shown, an embodiment of the present invention provides an assembled composite panel support structure, including a support component installed between two adjacent prefabricated panels 2, the support component is used to reinforce and seal between the prefabricated panel 2 and the template 1, and the support component is connected to the prefabricated panel 2 and the template 1; an avoidance hole 101 is opened on the template 1, the prefabricated panel 2 is placed on the top of the template 1, and steel bars are protruding on both sides of the prefabricated panel 2. There is a gap between the two adjacent prefabricated panels 2, and a plate belt beam steel bar 7 is placed on the top of the template 1 in the gap, and the plate belt beam steel bar 7 is wrapped with binding steel bars 8. The binding steel bars 8 and the plate belt beam steel bars 7 are fixed by winding fine steel wires. The support structure provided by the present application is mainly used for the construction process manufacturing of assembled composite panels At present, the specific construction process of the assembled composite slab is as follows: first, the prefabricated slab 2 is hoisted to the top of the template 1 by a hoisting machine with manual assistance, and then the plate-belt beam steel bars 7 are placed between two adjacent prefabricated slabs 2. After the plate-belt beam steel bars 7 are placed, the plate-belt beam steel bars 7 are tied with the help of binding steel bars 8. The binding steel bars 8 are soft steel bars that can be bent and deformed under the bending of the operator during actual use. The binding steel bars 8 are sleeved and tied to the outside of the plate-belt beam steel bars 7, and finally the two are locked and fixed with the help of fine steel wire. After the plate-belt beam steel bars 7 are tied, the assembled composite slab can be poured with concrete. The above process is disclosed as a prior art in this application, so it will not be described in too much detail. In the present application, according to the construction process of the prefabricated composite slab, by setting up a support component, not only can the sealing between the prefabricated slab 2 and the formwork 1 be improved, so that during the pouring of concrete on the composite slab, the concrete will not leak out from the gap between the prefabricated slab 2 and the formwork 1, thereby improving the effect of concrete pouring and saving the manpower and material resources consumed by additional grinding. Secondly, the setting of the support component can also assist the operator in hoisting the prefabricated slab 2, thereby improving the efficiency of hoisting the prefabricated slab 2 onto the formwork 1. In addition, the support component can assist the operator in binding the plate-belt beam steel bars 7, thereby improving the efficiency of binding the plate-belt beam steel bars 7. In summary, by setting up the support component, a more efficient construction process can be provided for the entire construction process of the prefabricated composite slab, thereby improving the construction efficiency on the basis of saving construction costs, and having a very high practical application value.
[0044] As an implementation method in this embodiment, Figures 1 to 14As shown, the support assembly has three usage states corresponding to: the precast panel 2 hoisting state, the plate-belt beam reinforcement 7 and the tied reinforcement 8 fixed state and the assembled composite panel concrete pouring state. In the precast panel 2 hoisting state: the support assembly includes a second limiting plate 5 inserted at the top of the template 1, the second limiting plate 5 is inserted in the gap between the two precast panels 2, both ends of the second limiting plate 5 are slidably connected with an L-shaped telescopic plate 6, the top of the second limiting plate 5 is screwed with a connecting rod 4, the outer wall of the connecting rod 4 is screwed with a first limiting plate 3, both ends of the first limiting plate 3 are installed with a guide part 301, the guide part 301 has an outwardly inclined angle, the first limiting plate 3 is symmetrically installed with a recessed part 302 and an anti-slip part 303, the recessed part 302 has a downwardly concave arc profile, and the surface of the anti-slip part 303 is provided with anti-slip grooves, the top and bottom of the second limiting plate 5 are fixedly connected with a mounting seat 501, and the mounting seat 501 is provided with Thread, the connecting rod 4 and the second limiting plate 5 are fixed by a mounting seat 501, the end of the L-shaped telescopic plate 6 close to the second limiting plate 5 is fixedly connected to the first mounting plate 601, one end of the first mounting plate 601 is fixedly connected to the elastic plate 602, and the end of the elastic plate 602 away from the first mounting plate 601 is fixedly connected to the second mounting plate 603, the first mounting plate 601 and the L-shaped telescopic plate 6 are fixed by screws, and the second mounting plate 603 and the second limiting plate 5 are fixed by screws, the first mounting plate 601, the elastic plate 602 and the second mounting plate 603 are an integrally manufactured structure, the elastic plate 602 is a curved elastic structure, the width of the second mounting plate 603 is greater than the width of the first mounting plate 601 and the elastic plate 602, the size of the mounting seat 501 is adapted to the size of the avoidance hole 101, the connecting rod 4 is screwed at the middle position of the first limiting plate 3, and the middle position of the first limiting plate 3 is thickened.
[0045] Specifically, the supporting assembly mainly includes a first limiting plate 3, a second limiting plate 5 and a connecting rod 4 for connecting the two, wherein a through hole is opened in the middle position of the first limiting plate 3, and a thread is arranged in the through hole, so that the user can screw the connecting rod 4 into the first limiting plate 3 by means of the through hole, and fix and adjust the height of the first limiting plate 3 by means of the thread, and mounting seats 501 are installed on the top and bottom of the second limiting plate 5, and the user can fix the ends of the connecting rod 4 on the top and bottom of the second limiting plate 5 through the mounting seats 501, and the two L-shaped telescopic plates 6 are both inserted into the second limiting plate 5, and the overall contour of the L-shaped telescopic plate 6 is "L"-shaped, The L-shaped expansion plate 6 is connected to the second limiting plate 5 by the screw thread, and the two L-shaped expansion plates 6 are connected to the second limiting plate 5 by the screw thread. The mounting plate 601 is fixed to the L-shaped telescopic plate 6 by screws, and the second mounting plate 603 is mounted on the outer wall of the second limiting plate 5 by screws. Since the size of the second mounting plate 603 is larger than that of the elastic plate 602 and the first mounting plate 601, the second mounting plate 603 can abut against the end of the limiting plate, so that the second mounting plate 603 will not be displaced during the process of the elastic plate 602 being deformed by the L-shaped telescopic plate 6 when it is extended and retracted. When the user presses the L-shaped telescopic plate 6 in the direction of the second limiting plate 5, the L-shaped telescopic plate 6 drives the elastic plate 602 to deform and gradually straighten. Therefore, when the two L-shaped telescopic plates 6 intersect, they will not be affected by the elastic plate 602. When the pressure on the L-shaped telescopic plate 6 stops, the elastic force of the elastic plate 602 will tend to cause the L-shaped telescopic plate 6 to slide in the opposite direction and return to its initial position. The above structure not only allows the two L-shaped telescopic plates 6 to freely extend and retract in the second limiting plate 5, but also prevents the two from blocking each other during the extension and retraction process. When the user stops pressing the L-shaped telescopic plate 6, the two L-shaped telescopic plates 6 can automatically reset, thereby improving the convenience of operation. Since the first mounting plate 601, the elastic plate 602 and the second mounting plate 603 are an integrated structure, the elastic part has a simpler processing technology during the production process and is easier to manufacture.
[0046] Through the description of the above structure, when the supporting assembly is in the state of hoisting the prefabricated panel 2, the operator can press the two L-shaped telescopic plates 6 to make the distance between the two L-shaped telescopic plates 6 smaller than the gap between the two adjacent prefabricated panels 2, and then let the L-shaped telescopic plates 6 and the second limiting plate 5 slide down to the top of the template 1. Since the size of the mounting seat 501 is compatible with the size of the avoidance hole 101 on the template 1, the mounting seat 501 is inserted into the avoidance hole 101 to achieve the limiting effect of the second limiting plate 5. Because the second limiting plate 5 needs to press a part of the L-shaped telescopic plate 6 into the second limiting plate 5 before sliding down, the elastic plate 602 will be deformed during the pressing process and the L-shaped The telescopic plate 6 applies a reverse thrust, so when the L-shaped telescopic plate 6 slides down to the top of the template 1, it will contact the inner walls on both sides of the template 1. At this time, with the help of the limiting effect of the mounting seat 501 and the avoidance hole 101, and the interference effect of the L-shaped telescopic plate 6 and the inner wall of the template 1, the stability of the entire support assembly structure can be improved. After the second limiting plate 5 is placed, the first limiting plate 3 is first screwed to the connecting rod 4, and then the end of the connecting rod 4 is screwed and fixed in the mounting seat 501 at the top of the second limiting plate 5. Finally, the height and angle of the first limiting plate 3 are rotated to adjust the direction in which the guide portion 301 is perpendicular to the direction in which the prefabricated panel 2 is hoisted, and the height is greater than the height of the prefabricated panel 2 placed on the surface of the template 1 (such as Figure 3 and Figure 4 As shown), the prefabricated panel 2 is hoisted at this time. Since the guide portion 301 has an outward tilt angle and the guide portion 301 is perpendicular to the hoisting direction of the prefabricated panel 2, the guide portion 301 can be used for auxiliary guidance during the displacement of the prefabricated panel 2 toward the template 1. At this time, the support assembly is installed at the four corners of the hoisting position of the prefabricated panel 2, which can fully guide the prefabricated panel 2. Under the auxiliary guiding effect of the guide portion 301, not only can the efficiency of the operator in hoisting the prefabricated panel 2 be improved, but also the placement position of the prefabricated panel 2 during the hoisting process can be more accurate.
[0047] In this embodiment, if Figure 5 , Figure 6 and Figure 12 to Figure 14As shown, when the slab-belt beam reinforcement 7 and the binding reinforcement 8 are fixed: the top of the recessed portion 302 conflicts with the bottom of the slab-belt beam reinforcement 7, and there is a gap between the bottom of the slab-belt beam reinforcement 7 and the top of the template 1. After the precast panel 2 is produced in the factory, reinforcement bars will extend from both sides, and the gap between two adjacent precast panels 2 will be staggered with reinforcement bars extending from the precast panels 2. At this stage, when the slab-belt beam reinforcement 7 is placed between the gaps of the precast panels 2, the reinforcement bars extending from both sides of the precast panels 2 will block the placement position of the slab-belt beam reinforcement 7. Therefore, the construction personnel cannot first tie the slab-belt beam reinforcement 7 and then put it into the gap of the precast panel 2. It is necessary to first place the slab-belt beam reinforcement 7 into the gap of the precast panel 2 and then use the binding reinforcement 8 to tie the slab-belt beam reinforcement 7. However, after the slab-belt beam reinforcement 7 is placed on the top of the template 1, it is limited by the space and the reinforcement bars on both sides of the precast panel 2. It is more laborious for the construction personnel to tie the slab-belt beam reinforcement 7 with the binding reinforcement 8, and there is a risk of being injured by the reinforcement bars.
[0048] When the slab-belt beam reinforcement 7 and the binding reinforcement 8 are fixed, the support assembly can assist the construction personnel in binding and fixing the slab-belt beam reinforcement 7. Specifically, the construction personnel first adjust the height of the first limit plate 3 by rotating the thread on the connecting rod 4, increase the distance between the first limit plate 3 and the second limit plate 5, and then lift the top of the slab-belt beam reinforcement 7 and place it on the top of the first limit plate 3. At this time, under the support of the first limit plate 3, the slab-belt beam reinforcement 7 will be lifted from the bottom of the template 1 by one end, so that its bottom and the top of the template 1 are separated from each other and there is a certain distance (such as Figure 5 and Figure 6 As shown), at this time, the construction workers can tie up the slab-belt beam reinforcement 7 lifted by the first limiting plate 3. After the slab-belt beam reinforcement 7 is lifted up, the construction workers have more space to wind and tie the reinforcement 8, and are not easily injured by the reinforcement extending from the prefabricated plate 2 during the winding process, thereby improving the efficiency of tying the slab-belt beam reinforcement 7 while improving the safety of the construction workers. Furthermore, a recessed portion 302 is provided on the first limiting plate 3. Since the recessed portion 302 has a downwardly concave arc-shaped contour, when the slab-belt beam reinforcement 7 is placed on the surface of the first limiting plate 3, the arc-shaped contour of the recessed portion 302 can be used to limit the slab-belt beam reinforcement 7, thereby improving the stability and safety of the slab-belt beam reinforcement 7 during the tying process.
[0049] In this embodiment, if Figures 7 to 14As shown, in the concrete pouring state of the assembled composite slab: the bottom of the L-shaped telescopic plate 6 is in contact with the top of the precast plate 2, the connecting rod 4 passes through the avoidance hole 101 and extends to the bottom of the template 1, the first limit plate 3 is screwed on the outer wall of the connecting rod 4, and the top of the first limit plate 3 is in contact with the bottom of the template 1. At this stage, the bottom of the template 1 and the precast plate 2 need to be sealed before concrete pouring of the composite slab. The most common sealing method is to use sponge rubber strips for blocking and sealing, but this sealing method is not effective and there is still leakage. After the template 1 is removed, the leakage position needs to be manually polished.
[0050] When the concrete of the assembled composite slab is in the pouring state, the support assembly can strengthen the seal between the prefabricated slab 2 and the formwork 1. Specifically, the construction personnel first press the L-shaped telescopic plate 6 to let it telescope into the second limit plate 5. When the L-shaped telescopic plates 6 on both sides of the second limit plate 5 are fully extended into the second limit plate 5, the overall width of the second limit plate 5 is smaller than the width of the plate-belt beam steel bar 7. Therefore, the user can remove the second limit plate 5 from the gap between the prefabricated panels 2 by pulling up. After the second limit plate 5 is taken out, stop pressing the L-shaped telescopic plate 6. Under the elastic action of the elastic plate 602, the L-shaped telescopic plate 6 will be reset. The reset L-shaped telescopic plate 6 makes the overall length of the second limit plate 5 greater than the two adjacent prefabricated panels. The gap between the prefabricated panels 2 is formed by unscrewing the connecting rod 4 from the top of the second limiting plate 5 and installing it in the mounting seat 501 at the bottom of the second limiting plate 5, and then placing the second limiting plate 5 on the top of the prefabricated panel 2. At this time, the second limiting plate 5 cannot pass through the gap between the prefabricated panels 2 due to the blocking effect of the two L-shaped telescopic plates 6. When the second limiting plate 5 is placed on the top of the prefabricated panel 2, the connecting rod 4 will pass through the avoidance hole 101 on the template 1 and then extend from the bottom of the template 1. At this time, the construction personnel screw the first limiting plate 3 to the bottom of the template 1. During the continuous screwing of the first limiting plate 3, the top of the first limiting plate 3 will squeeze the bottom of the template 1 and make the template 1 and the prefabricated panel 2 become tighter (such as Figures 9 to 11 As shown), under the action of the connecting rod 4, the first limiting plate 3 and the second limiting plate 5 will produce a pulling effect between the precast plate 2 and the template 1, thereby improving the sealing between the precast plate 2 and the template 1 and preventing the side leakage of concrete during the pouring process.
[0051] The working principle of the technical solution provided by the present invention is as follows:
[0052] When hoisting the prefabricated panel 2, the operator presses the two L-shaped telescopic plates 6 to make the distance between the two L-shaped telescopic plates 6 smaller than the gap between the two adjacent prefabricated panels 2, and then lets the L-shaped telescopic plates 6 and the second limiting plate 5 slide down to the top of the template 1. When the second limiting plate 5 is placed, the first limiting plate 3 is first screwed to the connecting rod 4, and then the end of the connecting rod 4 is screwed and fixed in the mounting seat 501 at the top of the second limiting plate 5. Finally, the height and angle of the first limiting plate 3 are rotated to adjust the guide portion 301 and the direction of hoisting the prefabricated panel 2 to be perpendicular to each other, and the height is greater than the prefabricated panel 2. The precast panel 2 is placed at a height equal to that on the surface of the template 1. At this time, the precast panel 2 is hoisted. Since the guide portion 301 has an outward tilt angle and the guide portion 301 is perpendicular to the hoisting direction of the precast panel 2, the guide portion 301 can be used for auxiliary guidance during the displacement of the precast panel 2 toward the template 1. At this time, the support assembly is installed at the four corners of the hoisting position of the precast panel 2, which can fully guide the precast panel 2. With the auxiliary guiding effect of the guide portion 301, not only can the efficiency of the operator in hoisting the precast panel 2 be improved, but also the placement position of the precast panel 2 can be more accurate during the hoisting process.
[0053] When tying the slab-belt beam reinforcement bars 7, the construction workers first adjust the height of the first limit plate 3 with the help of the threaded rotation on the connecting rod 4, increase the distance between the first limit plate 3 and the second limit plate 5, and then lift the top of the slab-belt beam reinforcement bar 7 and place it on the top of the first limit plate 3. At this time, under the support of the first limit plate 3, the slab-belt beam reinforcement bar 7 will be lifted from the bottom of the formwork 1 by one end, so that its bottom and the top of the formwork 1 are separated from each other and there is a certain distance. At this time, the construction workers can tie the slab-belt beam reinforcement bar 7 lifted by the first limit plate 3. After the slab-belt beam reinforcement bar 7 is lifted, the construction workers have more space to wrap and tie the reinforcement bar 8, and are not easily pierced by the reinforcement bar extending from the prefabricated plate 2 during the winding process, thereby improving the efficiency of tying the slab-belt beam reinforcement bar 7 while improving the safety of the construction workers.
[0054] When pouring concrete for the assembled composite slab, the construction workers first press the L-shaped telescopic plate 6 to make it telescope into the second limit plate 5. When the L-shaped telescopic plates 6 on both sides of the second limit plate 5 are fully extended into the second limit plate 5, the overall width of the second limit plate 5 is smaller than the width of the plate belt beam reinforcement 7. Therefore, the user can remove the second limit plate 5 from the gap between the prefabricated panels 2 by pulling up. After the second limit plate 5 is taken out, the pressing of the L-shaped telescopic plate 6 is stopped. Under the elastic action of the elastic plate 602, the L-shaped telescopic plate 6 will be reset. The reset L-shaped telescopic plate 6 makes the overall length of the second limit plate 5 larger than the gap between the two adjacent prefabricated panels 2. At this time, the connecting rod 4 is screwed down from the top of the second limit plate 5 and installed in the mounting seat 501 at the bottom of the second limit plate 5, and then the second The limiting plate 5 is placed on the top of the precast plate 2. At this time, the second limiting plate 5 cannot pass through the gap between the precast plates 2 due to the blocking effect of the two L-shaped telescopic plates 6. When the second limiting plate 5 is placed on the top of the precast plate 2, the connecting rod 4 will pass through the avoidance hole 101 on the template 1 and then extend from the bottom of the template 1. At this time, the construction personnel screw the first limiting plate 3 to the bottom of the template 1. During the continuous screwing of the first limiting plate 3, the top of the first limiting plate 3 will squeeze the bottom of the template 1 and make the template 1 and the precast plate 2 tighter. Under the action of the connecting rod 4, the first limiting plate 3 and the second limiting plate 5 will produce a pulling effect between the precast plate 2 and the template 1, thereby improving the sealing between the precast plate 2 and the template 1 and preventing the side leakage of concrete during the pouring process.
