Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of beam transfer layer construction, in particular to a concrete structure beam transfer layer construction method. BACKGROUND
[0002] The beam transfer layer in the concrete structure is a common structure form in high-rise buildings, which is used to transfer the load of the upper small column spacing or shear wall to the lower large column spacing structure. Its construction method is relatively complex, and the quality needs to be strictly controlled, especially the safe and reliable support system needs to be built.
[0003] The existing support system of the transfer beam mainly uses vertical poles, which are densely arranged under the transfer beam, and the bottom of the vertical pole is provided with a pad or a base; longitudinal and transverse vertical scissors supports and horizontal scissors supports (at least three at the top, middle and bottom) are arranged to form a stable space structure. The support area around and inside the transfer beam is reinforced. The adjustable jacks are used at the top of the vertical pole to facilitate accurate adjustment of the elevation and removal.
[0004] The existing support system used in the beam transfer layer has the following disadvantages: although the existing support system used in the transfer beam can effectively achieve support, if the compaction degree of the backfill foundation of the first layer support is not enough, significant settlement will occur under the load. Or the soft soil layer is not treated: the soft soil layer such as silt and silt soil is not treated by replacement, ramming or pile foundation. Or the vertical pole is not provided with a pad, or the area of the pad is too small, resulting in local pressure exceeding the bearing capacity of the foundation or floor; or there are local cavities, pipeline trenches, insufficient backfill and different soil layer junctions under the support area, resulting in significant difference in bearing capacity at different positions, etc. The settlement of the foundation may occur due to the above reasons. However, once the settlement occurs, the existing support system cannot effectively support, so that the transfer beam at the local position cannot be supported, which may cause collapse and other problems. SUMMARY
[0005] The purpose of the present application is to provide a concrete structure beam transfer layer construction method to solve the technical problems in the prior art that the support system built during the construction of the concrete structure beam transfer layer cannot effectively support when the foundation settles, so that the transfer beam at the local position cannot be supported, which may cause collapse and other problems.
[0006] The technical problem solved by the present application can be achieved by the following technical scheme: A concrete structure beam transfer layer construction method, the specific steps are as follows: First step, support system design: according to the transfer beam section, span and required concrete dead load, a support column mechanism for settlement is designed; The second step is the construction of the support system: the foundation is hardened, then the lines are laid out and positioned, and the support column mechanism to cope with settlement is installed based on the positions of the laid-out lines and positions. Step 3: Assemble the transfer beam formwork: Assemble the bottom and side formwork of the transfer layer, and connect the top of the support column mechanism for dealing with settlement with the bottom formwork; Step 4: Concrete pouring and curing: Concrete is poured in two layers. The lower layer is poured first, with an interval of no more than one hour, and then the upper layer is poured. After completion, geotextile is placed on the concrete, and the concrete is kept moist by an automatic spraying system.
[0007] Step 5: Demolding and dismantling of the support system.
[0008] A settlement-resistance support column mechanism includes multiple support modules, each of which includes an upper support and a lower support. The upper support is used to connect with the bottom formwork of a transfer beam. The upper support includes auxiliary connectors for connecting adjacent upper support modules. The lower support is used to support the foundation and can be detachably spliced below the upper support. An automatic connector is provided between the lower and upper support modules. When foundation settlement occurs, the lower support descends relative to the upper support, and the automatic connector connects the separated positions of the lower and upper support modules.
[0009] Preferably, the upper support member includes a top support plate and an upper column, the top support plate is fixedly connected to the top of the upper column, the auxiliary connector is used to be fixedly connected to the top support plate, and the bottom of the upper column is used to splice with the top of the lower support member.
[0010] Preferably, the lower support includes a support base plate and a lower column. The support base plate is fixedly connected to the bottom of the lower column, and the top of the lower column is spliced together with the bottom of the upper column. The top support plate corresponding to each support module is connected to the adjacent support module through an auxiliary connector.
[0011] Preferably, the top of the lower column is fixedly connected to a plug-in post, and the bottom of the upper column is provided with a plug-in groove that mates with the plug-in post.
[0012] Preferably, the automatic connector includes a fixed sleeve, a main horizontal insert steel plate, and an anti-reverse locking mechanism. The fixed sleeve is fitted onto the top of the lower support member and is fixedly connected to the upper support member. Multiple main horizontal insert steel plates are arranged circumferentially on the top of the fixed sleeve. Each main horizontal insert steel plate slides laterally through the side wall of the fixed sleeve, and the upper surface of the main horizontal insert steel plate is flush with the bottom end face of the upper support member. A first elastic connector connects the main horizontal insert steel plate to the fixed sleeve. When the lower support member descends relative to the upper support member due to a ground subsidence, the main horizontal insert steel plate relies on the first elastic connector to release its elastic force and horizontally inserts into the bottom of the upper support member. The anti-reverse locking mechanism is configured between the fixed sleeve and the lower support member to prevent the lower support member from sliding upwards relative to the fixed sleeve.
[0013] Preferably, the anti-reverse locking mechanism includes a reverse rack and elastic locking plates. The reverse rack is fixedly connected to the top outer wall of the lower support member. Multiple elastic locking plates are longitudinally distributed, and each elastic locking plate slides through the fixed sleeve. A second elastic connector is connected between the elastic locking plate and the fixed sleeve.
[0014] Preferably, the support base plate is provided with an extension mechanism, which is used to expand the support surface when the foundation settles, and a linkage mechanism is provided between the extension mechanism and the main horizontal insert steel plate.
[0015] Preferably, the expansion mechanism includes a mounting groove and a flip-up buckle. The mounting groove is formed on the supporting base plate, and the flip-up buckle is fitted into the mounting groove. One end of the flip-up buckle is connected to the mounting groove by an elastic rotating mechanism. The flip-up buckle flips and buckles onto the foundation around the supporting base plate through the elastic rotating mechanism. The supporting base plate is also provided with a rotating stop for locking the flip-up buckle. The rotating stop is connected to a linkage mechanism. The rotating stop covers the flip-up buckle and can rotate in the horizontal plane.
[0016] Preferably, when the main horizontal insert steel plate is inserted laterally to the bottom of the upper support member, the linkage mechanism triggers the flipping buckle to flip.
[0017] The beneficial effects of this invention are: This invention uses interconnected upper and lower support components as support assemblies for the transfer beam. When the foundation settles at a local location, the lower support component descends with the foundation, while the upper support component is attached to surrounding objects by auxiliary connectors. The main horizontal insert steel plate, which is conveniently designed, is ejected to the bottom of the upper support component. At the same time, the anti-reverse locking mechanism prevents the descending lower support component from approaching the upper support component. Thus, together with the main horizontal insert steel plate, the support performance of the upper support component can be effectively guaranteed, avoiding the loss of support performance due to foundation settlement.
[0018] The anti-reverse locking mechanism of this invention is designed with a reverse rack and multiple longitudinally distributed elastic locking plates to effectively ensure that the lower support can descend during foundation settlement, while also preventing the lower support from approaching the upper support after descending, thus ensuring that the fixed sleeve and the main horizontal insert steel plate perform their supporting functions.
[0019] When the main horizontal steel plate of this invention is ejected to the bottom of the lower support member, it pulls the rotating block by the traction steel wire, so that the rotating block is disengaged from the top of the flip-up buckle. The flip-up buckle is then flipped and fastened to the surrounding foundation by the rebound force of the coil spring. Furthermore, due to the unidirectional rotation of the ratchet and pawl combination, it is ensured that the flip-up buckle can effectively provide support after it is flipped and unfolded, thus preventing the lower support member from continuing to descend as the foundation descends.

[0022] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0023] like Figure 1 As shown, a construction method for a concrete beam-type transfer floor is described, with the following specific steps: Step 1: Support System Design: Based on the cross-section, span, and required concrete self-weight of the transfer beam, calculate the load, design a support column mechanism to cope with settlement, and set the spacing of the support column mechanism to cope with settlement. The second step is the erection of the support system: the foundation is hardened, then the layout and positioning are carried out, the support column mechanism to cope with settlement is assembled, and the support column mechanism to cope with settlement is installed based on the layout and positioning positions. Step 3: Assemble the transfer beam formwork: Assemble the bottom and side formwork of the transfer layer, and connect the top of the support column mechanism for dealing with settlement with the bottom formwork. The support column mechanism for dealing with settlement can be used to remedy the situation when the foundation settles. Step 4: Concrete pouring and curing: Concrete is poured in two layers. The lower layer is poured first, with an interval of no more than 2 hours, and then the upper layer is poured. Finally, the concrete is vibrated with an immersion vibrator, and multiple locations are vibrated at set intervals. After completion, geotextile is placed on the concrete, and the concrete is kept moist by an automatic spraying system.
[0024] Step 5: Formwork Removal and Support System Dismantling: Test the concrete strength of the transfer beam. When the concrete strength is greater than 1.2 MPa, remove the side formwork. When the concrete strength reaches the design strength, remove the support system and the bottom formwork.
[0025] like Figures 2 to 10As shown, the aforementioned support column mechanism for coping with settlement includes multiple support modules. Each support module includes an upper support 1 and a lower support 24. The upper support 1 is used to connect with the bottom formwork of the transfer beam. The upper support 1 includes auxiliary connectors 4 for connecting adjacent upper support modules. That is, adjacent support modules are connected by auxiliary connectors 4. The auxiliary connectors 4 have a weak support function, only playing a simple connection role and not bearing a large load. The main support still relies on the cooperation of the upper support 1 and the lower support 24. The auxiliary connectors 4 are set here mainly to ensure that the upper support 1 does not immediately descend when the foundation settles. It should be noted that the auxiliary connector 4 can be a rod or a steel cable, and if the auxiliary connector 4 on each support module cannot be connected to the support module at an adjacent position, such as if one side is a wall, it can also be connected to the wall; the lower support 24 is used to support on the foundation, and the lower support 24 can be detachably spliced below the upper support 1; an automatic connector is provided between the lower support 24 and the upper support 1. When the foundation settles, the lower support 24 descends relative to the upper support 1, and the automatic connector is used to connect the lower support 24 and the upper support 1 at their separated positions, thereby ensuring that the lower support 24 can still support the upper support 1.
[0026] In some specific implementation plans, such as Figure 3 As shown, the upper support 1 includes a top support plate 3 and an upper column 2. The top support plate 3 is fixedly connected to the top of the upper column 2. An inclined brace can also be installed between the top support plate 3 and the upper column 2 to ensure stability. The auxiliary connector 4 is used to fix the top support plate 3. The bottom of the upper column 2 is used to splice with the top of the lower support 24.
[0027] In some specific implementation plans, such as Figure 5 As shown, the lower support 24 includes a support base plate 5 and a lower column 12. The support base plate 5 is fixedly connected to the bottom of the lower column 12. The top of the lower column 12 is spliced together with the bottom of the upper column 2. The top support plate 3 of each support module is connected to the adjacent support module through the auxiliary connector 4. When the foundation settles, the support base plate 5 carries the lower column 12 down relative to the upper column 2. The specific splicing method of the lower column 12 and the upper column 2 is as follows: The top of the lower column 12 is fixedly connected to a plug-in column 15, and the bottom of the upper column 2 is provided with a plug-in groove 14 that mates with the plug-in column 15. The diameter of the plug-in column 15 is smaller than the diameter of the lower column 12, so that the upper column 2 can be supported on the lower column 12 after being spliced. The plug-in column 15 and the plug-in groove 14 are used to guide the lower column 12 to descend vertically and avoid tilting.
[0028] In some specific implementation schemes, refer to Figures 3 to 6As shown, the automatic connector includes a fixed sleeve 11, a main horizontal insert steel plate 6, and an anti-reverse locking mechanism. The fixed sleeve 11 is fitted onto the top of the lower support member 24, specifically onto the top of the lower column 12 of the lower support member 24. The fixed sleeve 11 is fixedly connected to the upper support member 1 via a rod, specifically, the fixed sleeve 11 is fixedly connected to the upper column 2 of the upper support member 1. Multiple main horizontal insert steel plates 6 are provided and are circumferentially distributed on the top of the fixed sleeve 11. Each main horizontal insert steel plate 6 slides laterally through the side wall of the fixed sleeve 11, and the upper surface of the main horizontal insert steel plate 6 is flush with the bottom end face of the upper support member 1. A first elastic connector is also connected between the main horizontal insert steel plate 6 and the fixed sleeve 11. The first elastic connector can be a spring or an elastic rubber body. Alternatively, when the lower support 24 and the upper support 1 are spliced together, the main horizontal insert steel plate 6 abuts against the top side of the lower support 24, and at this time the first elastic connector is in a stretched state. When the lower support 24 descends relative to the upper support 1 due to the foundation descent, the end of the main horizontal insert steel plate 6 loses its obstruction, and thus relies on the elastic force released by the first elastic connector to horizontally insert to the bottom of the upper support 1 and fit against the bottom of the upper support 1. The anti-reverse locking tooth mechanism is set between the fixed sleeve 11 and the lower support 24. The anti-reverse locking tooth mechanism is used to prevent the lower support 24 from sliding upward relative to the fixed sleeve 11, and can only slide downward. This avoids hindering the descent of the lower support 24 relative to the upper support 1, and facilitates the release of the main horizontal insert steel plate 6.
[0029] In some specific implementations, the anti-reverse tooth-locking mechanism includes a reverse toothed rack 13 and an elastic locking plate 7. The reverse toothed rack 13 is fixedly connected to the top outer wall of the lower support member 24, specifically to the lower column 12 of the lower support member 24. Multiple reverse teeth are distributed longitudinally and equidistantly on the reverse toothed rack 13. The lower side of each reverse tooth is a slope and the upper side is a right angle. Multiple elastic locking plates 7 are distributed longitudinally. Each elastic locking plate 7 slides through the fixed sleeve 11, and a second elastic connector is connected between the elastic locking plate 7 and the fixed sleeve 11. Each elastic locking plate 7 always abuts against the reverse toothed rack 13, and the second elastic connector remains in a stretched state and has a rebound force.
[0030] As the reverse rack 13 descends with the lower support member 24, the reverse teeth on the reverse rack 13 rely on the inclined plane to squeeze through each elastic clamping plate 7 during the descent. The elastic clamping plate 7 at the position of the reverse teeth will be above the right angle surface of the corresponding reverse teeth. In this way, the upper support member 1 transmits the load downward to the main horizontal insert steel plate 6. The main horizontal insert steel plate 6 then acts on each elastic clamping plate 7 through the fixed sleeve 11. Each elastic clamping plate 7 is blocked by the reverse rack 13 and cannot descend, thereby ensuring that even if the upper support member 1 and the lower support member 24 are separated, they can still provide support and avoid the inability to provide normal support due to the settlement of the lower support member 24.
[0031] It should be noted that the distribution density of the elastic clamping plate 7 can be selected according to actual needs, ensuring that after the lower support member 24 descends relative to the fixed sleeve 11 with the reverse rack 13, the fixed sleeve 11 can also rely on the action of the elastic clamping plate 7 to prevent downward movement relative to the lower support member 24.
[0032] In addition, the first elastic connection and the second elastic connection can be set on both sides of the corresponding plate as needed, which is the prior art and will not hinder the movement of the main horizontal insert steel plate 6 and the elastic clamping plate 7.
[0033] In some specific implementation schemes, an extension mechanism is provided on the support base plate 5. The extension mechanism is used to expand the support surface when the foundation settles to prevent further settlement. The number of extension mechanisms corresponds to the number of main horizontal steel plates 6, and a linkage mechanism is provided between the extension mechanism and the main horizontal steel plates 6.
[0034] In some specific implementation plans, such as Figure 5 , Figure 9 and Figure 10 As shown, the extension mechanism includes a mounting groove 17 and a flip-up buckle 16. The mounting groove 17 is formed on the supporting base plate 5. The flip-up buckle 16 is fitted into the mounting groove 17, and one end of the flip-up buckle 16 is connected to the mounting groove 17 by an elastic rotating mechanism. The flip-up buckle 16 flips and buckles onto the foundation around the supporting base plate 5 through the elastic rotating mechanism. The elastic rotating mechanism includes a connecting shaft 23, a ratchet 21, and a pawl 22. The connecting shaft 23 is fixedly connected to one end of the flip-up buckle 16, and the connecting shaft 23... The connecting shaft 23 is rotatably connected to the inner wall of the mounting groove 17. A coil spring connects the connecting shaft 23 and the mounting groove 17. When the flip-up buckle 16 is stored inside the mounting groove 17, the coil spring is in a tightened state and has a rebound force. The ratchet 21 is fixedly connected inside the mounting groove 17, and the ratchet 21 is an annular body that fits around the outside of the connecting shaft 23. At the same time, the inner ring of the ratchet 21 has grooves that cooperate with the pawl 22. The pawl 22 is movably connected to the connecting shaft 23 through a spring-loaded hinge, and the pawl 22 and the ratchet 21 cooperate to... Figure 10 From a visual perspective, the right side of the pawl 22 connection end is movably connected to the connecting shaft 23 via a spring-loaded hinge, and the pawl 22 connection end is in contact with the connecting shaft 23; the support base plate 5 is also provided with a rotating stop 18 for locking the flip buckle 16, and the rotating stop 18 is connected to the linkage mechanism. The rotating stop 18 covers the flip buckle 16, and the rotating stop 18 can rotate in the horizontal plane.
[0035] In some specific implementation plans, combined with Figure 4 and Figure 9As shown, when the main horizontal insert steel plate 6 is inserted laterally to the bottom of the upper support member 1, the linkage mechanism triggers the flipping buckle 16 to flip. The linkage mechanism includes a first bracket 9, a traction steel wire 8, and a second bracket 19. The first bracket 9 is fixedly connected to the outer wall of the fixed sleeve 11. One end of the traction steel wire 8 is connected to the main horizontal insert steel plate 6, and the other end is connected to the corresponding rotating stop 18. The first bracket 9 is provided with a first fixed pulley 10 that cooperates with the traction steel wire 8. The second bracket 19 is fixedly connected to the first bracket 9, and the end of the second bracket 19 extends to a position close to the rotating stop 18. The rotating stop 18 and the second bracket 19 are rotatably connected through a vertically arranged rotating shaft. An auxiliary bracket is fixedly connected to one end of the second bracket 19 near the rotating stop 18. The second bracket 19 is connected to a second fixed pulley 20 that cooperates with the traction steel wire 8 through the auxiliary bracket.
[0036] When the main horizontal insert steel plate 6 is inserted horizontally to the bottom of the upper support member 1, it pulls the traction steel wire 8, causing the traction steel wire 8 to pull the rotating stop block 18 to deflect under the guidance of the first fixed pulley 10 and the second fixed pulley 20, deflecting it away from the flip buckle plate 16. The flip buckle plate 16 then flips by the rebound force of the coil spring and is fastened to the surrounding foundation. At this time, due to the cooperation of the ratchet 21 and the pawl 22, the flip buckle plate 16 cannot rotate back, thus facilitating effective auxiliary support and preventing the lower support member 24 from continuing to descend due to the settlement of the foundation at its location.
[0037] Some cones can be distributed on the flip-up buckle 16 to enhance the buckling effect.
[0038] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: After the side formwork, bottom formwork and support column mechanism for dealing with settlement of the transfer beam are set up, if the foundation at the location of a certain support module settles, when the lower support 24 descends relative to the upper support 1 due to the foundation descending, the end of the main horizontal insert steel plate 6 loses its obstruction, and thus relies on the first elastic connector to release the elastic force to insert horizontally to the bottom of the upper support 1 and fit against the bottom of the upper support 1. As the lower support member 24 descends, the reverse rack 13's reverse teeth, through the inclined plane, press against each elastic clamping plate 7 during its descent. The elastic clamping plate 7 at the reverse tooth position will be above the right angle of the corresponding reverse tooth. Thus, the upper support member 1 transmits the load downward to the main horizontal insert steel plate 6, which in turn acts on each elastic clamping plate 7 through the fixing sleeve 11. Each elastic clamping plate 7 is blocked by the reverse rack 13 and cannot descend, thereby ensuring that even if the upper support member 1 and the lower support member 24 are separated, they can still provide support. This prevents the lower support member 24 from failing to provide normal support due to settlement and ensures that support can still be maintained after settlement.
[0039] Furthermore, when the main horizontal insert steel plate 6 is inserted horizontally to the bottom of the upper support member 1, it pulls the traction steel wire 8, causing the traction steel wire 8 to pull the rotating stop block 18 to deflect under the guidance of the first fixed pulley 10 and the second fixed pulley 20, deflecting it away from the flip buckle plate 16. The flip buckle plate 16 then flips by the rebound force of the coil spring and is fastened to the surrounding foundation. At this time, due to the cooperation of the ratchet 21 and the pawl 22, the flip buckle plate 16 cannot rotate back, thus facilitating effective auxiliary support and preventing the lower support member 24 from continuing to descend due to the settlement of the foundation at its location.
[0040] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
