Description

TECHNICAL FIELD

[0002] The building floor slab refers to the horizontal structure between each floor of a building, which is usually made of concrete, reinforced concrete or prestressed concrete, and serves to support the upper structure and distribute the load. The double-T slab is a common form of floor slab, which has a double-T-shaped cross section, high bearing capacity and large span, and is widely used in the floor slab system of industrial buildings and large commercial buildings. The double-T slab is often used as a form of floor slab.

[0003] A prestressed reinforced concrete double-T slab for the building industry, a mold bed and a production method thereof are disclosed in Chinese Patent No. 200910028173.3. The double-T slab includes two rib beams and a panel, and the panel of the double-T slab is provided with lifting holes at both sides of the two ends of the rib beams. The mold bed includes a mold plate and a prestressed pressure plate, and the top plane of the mold plate is provided with protrusions corresponding to the lifting holes of the double-T slab at both sides outside the mold groove. The two ends of the mold groove of the mold plate are provided with mold end plates, and the mold end plates are provided with steel bar holes and lifting holes or lifting rings or lifting hooks. The method includes finally connecting the lifting holes or lifting rings or lifting hooks of the mold end plates with lifting devices, and the double-T slab is lifted out of the mold bed together with the mold end plates. The prestressed reinforced concrete double-T slab is safe and reliable, low in cost, and the mold bed is low in manufacturing cost, and the method is efficient and low in production cost.

[0004] When the double-T slab is installed as a floor slab, the butt joint between two double-T slabs often causes collision problems, resulting in damage. When the double-T slab is skewed, it is usually manually controlled by a crane to be straightened, which tests the operation level of the crane. In addition, many wooden formworks are usually needed to be installed for pouring during the installation of the double-T slab, and then the formworks are dismantled, which causes trouble in installation.

[0016] The application also claims a method for installing the floor prestressed concrete double T plate with the linkage adjusting function, comprising the following steps:

[0017] S1, placing the double T plate body on the two cross beams in sequence by a crane, and the placing mode is that the left rib beam and the right rib beam are first placed close to the corresponding cross beam, and then the double T plate body is moved along the direction of the cross beam;

[0018] S2, the active buffer plate of the latter double T plate body first contacts the passive buffer plate of the former installed double T plate body, if the latter double T plate body is skewed, the active buffer plate of the latter double T plate body will not be attached to the passive buffer plate on all surfaces, at this time, the distance between the active buffer plate of the latter double T plate body and the latter double T plate body is shortened, so that the abnormality can be quickly found; and the passive buffer plate of the former double T plate body is elastically compressed for buffering; at this time, the orientation of the two double T plate bodies can be quickly adjusted and aligned without contacting each other, until the active buffer plate of the latter double T plate body is attached to the passive buffer plate of the former double T plate body, at this time, the moving direction of the crane is also adjusted.

[0019] S3, continue to move the next double T plate body, the active buffer plate will first be attached to the side of the panel of the next double T plate body, then push the passive buffer plate of the previous double T plate body, until the passive buffer plate of the previous double T plate body is attached to the side of the panel of the previous double T plate body, at this time the attachment of the two double T plate bodies is completed, and the locking rod extends through the corresponding slot, so that the buffer spring is finally locked; the buffer spring on the side of the passive buffer plate plays a buffering role throughout the process, avoiding rigid collision;

[0020] S4, continuously cycle S1-S3 to complete the installation of multiple double T plate bodies, while forming a closed groove between adjacent panels; then pouring concrete into the closed groove;

[0021] S5, after the concrete solidifies, the active slide pipe and the passive slide rod are quickly disassembled by disassembling the adjusting steel plate; then continue to install the adjusting steel plate, control the screw rod to make the semicircular block abut against the semicircular steel plate; and reuse the disassembled active slide pipe and passive slide rod.

[0022] Compared with the prior art, the present application has the following beneficial effects:

[0023] (1) The application can quickly adjust the orientation and align the two double T plate bodies without contact, and avoid rigid collision during installation, by the cooperation of the double T plate body and the active sliding pipe and the passive sliding rod. Specifically, the crane places the double T plate body on the two beams in turn, and the placement method is to first make the left and right rib beams end close to the corresponding beam, and then move the double T plate body along the beam direction. At this time, the active buffer plate of the latter double T plate body will first contact the passive buffer plate of the former installed double T plate body. If the latter double T plate body is skewed, the active buffer plate of the latter double T plate body will not be fully in contact with the passive buffer plate, the active buffer plate of the latter double T plate body will shorten the distance from the latter double T plate body, which is convenient and fast to find abnormalities. The passive buffer plate of the former double T plate body is elastically compressed for buffering. At this time, the orientation of the two double T plate bodies can be quickly adjusted and aligned without contact, until the active buffer plate of the latter double T plate body is fully aligned with the passive buffer plate of the former double T plate body, and the moving direction of the crane is also adjusted. Thus, the orientation of the two double T plate bodies can be quickly adjusted and aligned without contact. Then continue to move the latter double T plate body, the active buffer plate will first contact one side of the panel of the latter double T plate body, then push the passive buffer plate of the former double T plate body, until the passive buffer plate of the former double T plate body is in contact with one side of the panel of the former double T plate body, the installation of the two double T plate bodies is completed at this time. The buffer spring on the side of the passive buffer plate plays a buffering role throughout the process, avoiding rigid collision during installation.

[0024] (2) The application can avoid rigid collision during installation of the two double T plate bodies, and also maintain the sealing of the closed groove between the adjacent panels, facilitate subsequent rapid pouring connection of concrete and disassembly of parts, greatly improve the efficiency, and thus no subsequent formwork operation is needed. Specifically, when the two double T plate bodies are installed, only the butt joint operation is realized, and due to the rebounding effect of the buffer spring, a gap may be caused at any time, therefore, by cooperating with the locking mechanism, the locking rod will extend out of the corresponding through slot at the same time of butt joint, so that the buffer spring is finally locked and cannot play the elastic role, at this time, the sealing of the closed groove between the adjacent panels can be ensured, and directly pouring concrete into the closed groove can realize rapid pouring connection. At the same time, after pouring and connecting, due to the action of the locking mechanism, the buffer spring is locked and cannot play the elastic role, therefore, without the limitation of force, the active sliding pipe and the passive sliding rod can be quickly disassembled through the limiting groove, greatly improving the efficiency, and thus no subsequent formwork operation is needed.

[0025] (3) The limiting mechanism structure of the present application can ensure the quick disassembly and recycling of the active sliding pipe and the passive sliding rod, and can also maintain the stability of the subsequent ribbed beam to prevent safety accidents. Specifically, when the active sliding pipe and the passive sliding rod need to be disassembled, after the concrete solidifies, the limiting groove is opened by disassembling the adjusting steel plate, so that the active sliding pipe and the passive sliding rod can be quickly disassembled and reused. After disassembly is completed, the adjusting steel plate is installed again, and a support structure is formed by the half-ring steel plate, the L-shaped steel plate and the adjusting steel plate to preliminarily prevent the limiting groove from breaking. At the same time, by controlling the screw rod, since the two sides of the block are attached to one side of the L-shaped steel plate, and the rotating disc on the screw rod is rotationally connected to the T-shaped groove of the block, the screw rod can be continuously raised to push the block by rotating the screw rod, so that the semicircular block abuts against the half-ring steel plate. At the same time, the filling of the semicircular block and the block improves the stability of the stress of the limiting groove, and comprehensively maintains the stability of the subsequent ribbed beam to prevent safety accidents.

The relative sequence of the steps can be adjusted. It can be understood that the term "and / or" used herein involves and covers any and all possible combinations of one or more of the associated listed items. EMBODIMENT

[0038] As Figures 1-8 shown, a floor prestressed concrete double T plate with linkage adjustment function comprises a double T plate body 100, the front and rear ends of the double T plate body 100 are placed on two cross beams, and a plurality of double T plate bodies 100 are arranged side by side to form a floor structure; the double T plate body 100 comprises a panel 110 and left and right rib beams 120 and 130 fixedly arranged at the bottom of the panel 110; the bottom of each of the left and right rib beams 120 and 130 is provided with two limiting grooves 140, thereby forming two groups of limiting grooves 140; an active sliding pipe 400 is slidably connected in each group of limiting grooves 140, the left ends of the two active sliding pipes 400 are fixedly connected with an active buffer plate 200, the right ends of the two active sliding pipes 400 are each provided with an outer limiting ring 420, and the outer limiting ring 420 is limited to abut against the outer side of the adjacent limiting groove 140; the right end of each of the two active sliding pipes 400 is slidably connected with a passive sliding rod 500, and the ends of the two passive sliding rods 500 are fixedly connected with a passive buffer plate 300; a buffer spring 520 is sleeved on the passive sliding rod 500, and the buffer spring 520 is located between the corresponding outer limiting ring 420 and the passive buffer plate 300.

[0039] The application can quickly adjust the orientation and right the position without contact between the two double T plate bodies 100, and can avoid rigid collision during installation. Specifically, the crane places the double T plate body 100 on the two beams in sequence, and the placement method is to first make the left rib beam 120 and the right rib beam 130 end close to the corresponding beam, and then move the double T plate body 100 along the beam direction. At this time, the active buffer plate 200 of the latter double T plate body 100 will first contact the passive buffer plate 300 of the former installed double T plate body 100. If the latter double T plate body 100 is skewed, the active buffer plate 200 of the latter double T plate body 100 will not be completely matched with the passive buffer plate 300, the active buffer plate 200 of the latter double T plate body 100 will be shortened in distance from the latter double T plate body 100, which facilitates quick detection of abnormalities. The passive buffer plate 300 of the former double T plate body 100 is elastically compressed for buffering. At this time, the orientation of the latter double T plate body 100 can be quickly adjusted and righted without contact between the two double T plate bodies 100, until the active buffer plate 200 of the latter double T plate body 100 is completely matched with the passive buffer plate 300 of the former double T plate body 100, and the moving direction of the crane is adjusted. Thus, the orientation of the latter double T plate body 100 can be quickly adjusted and righted without contact between the two double T plate bodies 100. Then, the latter double T plate body 100 is continuously moved, the active buffer plate 200 is first matched with one side of the panel 110 of the latter double T plate body 100, then pushes the passive buffer plate 300 of the former double T plate body 100, until the passive buffer plate 300 of the former double T plate body 100 is matched with one side of the panel 110 of the former double T plate body 100, so that the matching and installation of the two double T plate bodies 100 are completed. The buffer spring 520 on one side of the passive buffer plate 300 plays a buffering role at all times during this process, avoiding rigid collision during installation.

[0040] It is worth noting that the active buffer plate 200 and the passive buffer plate 300 can be of a wooden structure, thereby improving the buffering performance, and the drawings in the specification of the application are only schematic and do not limit the specific dimensions, which are not described in detail.

[0041] Further, the passive sliding rod 500 is symmetrically provided at one end with two locking mechanisms 700, the locking mechanism 700 comprises a locking rod 710 and a reset spring 720 connected with each other; the passive sliding rod 500 is symmetrically provided at one end with two accommodating grooves 510, and the bottom of each accommodating groove 510 is fixedly connected with one end of the corresponding reset spring 720.

[0042] The application can avoid rigid collision of two double T plate bodies 100 during installation, maintain the sealing of the closed groove between the adjacent panels 110, facilitate subsequent rapid pouring connection of concrete and disassembly of components, greatly improve efficiency, and thus eliminate the need for subsequent formwork operation.

[0043] Further, two through grooves 410 are symmetrically arranged on the active sliding pipe 400, and the through grooves 410 correspond to the locking rods 710; when the double T plate body 100 is placed in front of the cross beam, the active buffer plate 200, the passive buffer plate 300 and the panel 110 have a gap; when the active buffer plate 200 and the passive buffer plate 300 abut against the panel 110, the locking rod 710 extends out of the corresponding through groove 410.

[0044] When the two double T plate bodies 100 are attached and installed, only the docking operation is realized, and due to the rebounding effect of the buffer spring 520, the gap may be generated at any time, so through the cooperation of the locking mechanism 700, the locking rod 710 extends out of the corresponding through groove 410 when docking, so that the buffer spring 520 is finally locked and cannot play the elastic role, at this time, the sealing of the closed groove between the adjacent panels 110 can be ensured, and at this time, the rapid pouring connection can be realized by directly pouring concrete into the closed groove; at the same time, after the pouring connection is completed, due to the effect of the locking mechanism 700, the buffer spring 520 is locked and cannot play the elastic role, so under the condition of no force, the active sliding pipe 400 and the passive sliding rod 500 can be quickly disassembled through the limiting groove 140, the efficiency is greatly improved, and thus the subsequent formwork operation is not needed.

[0045] Further, the limiting groove 140 is provided with a limiting mechanism 600, the limiting mechanism 600 comprises a half-ring steel plate 610, two ends of the half-ring steel plate 610 are symmetrically provided with L-shaped steel plates 620; the half-ring steel plate 610 and the L-shaped steel plate 620 are attached to the inner wall of the limiting groove 140; the bottom of the L-shaped steel plate 620 is fixedly connected with the bottom of the corresponding rib by anchor bolts; the bottoms of the two L-shaped steel plates 620 are fixedly connected with an adjusting steel plate 680 by bolts; a threaded hole 681 is formed in the middle of the adjusting steel plate 680, a screw rod 660 is screwed in the threaded hole 681, and the end of the screw rod 660 is rotatably connected with a limiting block.

[0046] Through the structural design of the limiting mechanism 600, the active sliding pipe 400 and the passive sliding rod 500 can be quickly disassembled and recycled, and the stability of the subsequent rib can be maintained to prevent safety accidents; the subsequent detailed description is as follows.

[0047] Further, the limiting block comprises a semicircular block 630 and a square block 640 fixedly connected with each other, two sides of the square block 640 are attached to one side of the L-shaped steel plate 620, a T-shaped groove 650 is fixedly arranged at the bottom of the square block 640, and a rotating disc 661 is fixedly arranged at the end of the screw rod 660, and the rotating disc 661 is rotationally connected with the T-shaped groove 650.

[0048] Further, the limiting groove 140 comprises a semicircular arc groove 141 and a straight groove 142 in communication with each other, the semicircular arc groove 141 is arranged in correspondence with the semicircular steel plate 610, and the straight groove 142 is arranged in correspondence with the L-shaped steel plate 620.

[0049] When the active sliding pipe 400 and the passive sliding rod 500 need to be disassembled, after the concrete is solidified, the adjusting steel plate 680 is disassembled, so that the limiting groove 140 is opened, thereby realizing quick disassembly of the active sliding pipe 400 and the passive sliding rod 500, and the active sliding pipe 400 and the passive sliding rod 500 disassembled can be reused; after disassembly is completed, the adjusting steel plate 680 is continued to be installed, a support structure is formed by the semicircular steel plate 610, the L-shaped steel plate 620 and the adjusting steel plate 680, and the limiting groove 140 is preliminarily prevented from being broken; at the same time, the screw rod 660 is controlled, since two sides of the square block 640 are attached to one side of the L-shaped steel plate 620, and the rotating disc 661 on the screw rod 660 is rotationally connected with the T-shaped groove 650 of the square block 640, the screw rod 660 can be continuously lifted to push the square block 640 by rotation of the screw rod 660, so that the semicircular arc block 630 abuts against the semicircular steel plate 610; at the same time, the filling of the semicircular arc block 630 and the square block 640 improves the stability of the stress of the limiting groove 140, and the stability of the subsequent ribbed beam is comprehensively maintained, so that a safety accident is prevented.

[0050] Further, the screw rod 660 is fixedly provided with an adjusting handle 670 at an end away from the limiting block. The adjusting handle 670 is convenient for adjusting the screw rod 660.

[0051] Further, the bottom outer end of the L-shaped steel plate 620 is spaced apart from the front end and the rear end of the corresponding ribbed beam, and is used for being placed on the cross beam.

[0052] Further, the active buffer plate 200 and the passive buffer plate 300 are higher than the bottom of the panel 110 and are lower than the top of the panel 110. Such a structure design is convenient for forming a closed groove.

10. A method for installing a prestressed concrete double-T slab with linkage adjustment function as described in any one of claims 1 to 9, characterized in that, Includes the following steps: S1. Place the double T plate body (100) on the two crossbeams in sequence using a crane. The placement method is to first bring the ends of the left rib beam (120) and the right rib beam (130) close to the corresponding crossbeams, and then move the double T plate body (100) along the direction of the crossbeams. S2. The active buffer plate (200) of the subsequent double-T plate body (100) will first contact the passive buffer plate (300) of the previously installed double-T plate body (100). If the subsequent double-T plate body (100) is crooked, then the active buffer plate (200) of the subsequent double-T plate body (100) will not be fully in contact with the passive buffer plate (300). At this time, the active buffer plate (200) of the subsequent double-T plate body (100) will contact the passive buffer plate (300) of the subsequent double-T plate body. (100) The distance is shortened, making it easier to quickly detect abnormalities; while the passive buffer plate (300) of the previous double T plate body (100) is elastically compressed for buffering; at this time, the orientation can be quickly adjusted and aligned without the two double T plate bodies (100) contacting each other, until the active buffer plate (200) of the next double T plate body (100) and the passive buffer plate (300) of the previous double T plate body (100) are fully aligned and in contact, and at this time the crane's movement direction has also been adjusted; S3. Continue moving the next double-T plate body (100). The active buffer plate (200) will first adhere to one side of the panel (110) of the next double-T plate body (100), and then push the passive buffer plate (300) of the previous double-T plate body (100) until the passive buffer plate (300) of the previous double-T plate body (100) adheres to one side of the panel (110) of the previous double-T plate body (100). At this time, the two double-T plate bodies (100) can be attached and installed, and the locking rod (710) extends out of the corresponding through slot (410) to lock the buffer spring (520) in the end. During this process, the buffer spring (520) on one side of the passive buffer plate (300) plays a buffering role to avoid rigid collision. S4. Repeat S1~S3 continuously to complete the installation of multiple double-T plate bodies (100), while forming a closed groove between adjacent panels (110); then pour concrete into the closed groove. S5. After the concrete has solidified, the active slide tube (400) and passive slide rod (500) are quickly disassembled by removing the adjusting steel plate (680); then the adjusting steel plate (680) is installed again, and the semi-circular block (630) is made to abut against the semi-circular steel plate (610) by controlling the screw (660); and the disassembled active slide tube (400) and passive slide rod (500) are reused.
