Description

Technical Field

[0001] This utility model relates to the field of floor slab construction auxiliary tools, specifically a male and female groove quick assembly and positioning fixture for composite bottom formwork floor slabs. Background Technology

[0002] Composite bottom formwork floor slabs are a common floor slab construction method in modern buildings. They typically refer to floor slab structures that use profiled steel sheets as permanent formwork (bottom formwork) and are combined with cast-in-place concrete layers through shear connectors to form an integral load-bearing floor slab structure. The male and female groove connections on the left and right sides of the vertical floor slabs are a key structural construction process. When vertically splicing two adjacent vertical floor slabs to form a continuous wall, the construction workers will calibrate the installation position of the floor slabs, use a level and measuring tools to ensure that the verticality and horizontality of the floor slabs meet the requirements, and then mark the position of the grooves in the corresponding locations. Next, ensure that the size and shape of the groove meet the design standards, and remove excess debris and dust from the male and female grooves of the floor slabs to provide a good foundation for subsequent connection. During connection, the workers will insert the male and female groove components into the groove, ensuring accurate insertion depth and position. Then, they will use steel bars or pre-embedded bolts to fix the two floor slabs together. During the tightening process, a torque wrench is used to ensure that the tightening force of the bolts and nuts is moderate to avoid affecting the firmness of the connection. However, at this stage, when connecting the male and female grooves of vertical floor slabs during the lifting process, the lifted vertical floor slabs are in a swaying and unstable state. The workers need to observe and manually adjust the position of the vertical floor slabs in the lifting state. After adjustment, the vertical floor slabs in the lifting state can be connected with the floor slabs in the fixed state below. During this process, the swaying and displacement of the floor slabs are uncertain, and the workers' operation is limited by visual observation and senses, which can easily lead to errors, resulting in floor slab position deviations and affecting the accurate connection of the male and female grooves. Utility Model Content

[0003] The purpose of this utility model is to provide a quick assembly and positioning fixture for male and female grooves of composite bottom formwork floor slabs. A C-shaped support frame is placed on one side of a fixed vertical floor slab, and the cavity in the C-shaped support frame is aligned with the male groove of the fixed vertical floor slab. The vertical floor slab in the lifting state slowly moves down along several double rollers in the cavity. The operator needs to adjust the support plate through the screw adjustment structure. The support plate limits the vertical floor slab in the lifting state and promotes the male and female grooves of the fixed floor slab and the lifting floor slab to complete the docking, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly and positioning fixture for male and female grooves in composite bottom formwork floor slabs, comprising a C-shaped support frame, a cavity inside the C-shaped support frame, and multiple double rollers rotatably installed at equal intervals in the vertical direction on one side inner wall of the C-shaped support frame. A support platform is slidably installed at the bottom of the C-shaped support frame, and an upwardly extending support plate is integrally formed at the top of the support platform. A screw adjustment structure for controlling the horizontal movement of the support platform and the support plate is also installed at the bottom of the C-shaped support frame.

[0005] Preferably, the C-shaped support frame is composed of two L-shaped double-layer frames with a mirror-symmetrical structure, and the opposite ends of the two L-shaped double-layer frames are bolted to each other.

[0006] Preferably, the C-shaped support frame and the support platform are made of aluminum alloy components, and the surface of the support plate is provided with a hollow groove.

[0007] Preferably, the bottom of the C-shaped support frame is fixed with two square tracks extending along the X-axis, and the bottom end of the support platform is equipped with a sliding groove that slides with the square tracks.

[0008] Preferably, the double roller includes a convex shaft rotatably mounted on the left and right inner walls of the C-shaped support frame, a square shaft fixed between the opposite ends of the two convex shafts, and steel wheels fitted at both ends of the surface of the square shaft.

[0009] Preferably, the lead screw adjustment structure includes an L-shaped base fixed to the bottom of the C-shaped support frame, a threaded rod rotatably mounted on the outer wall of one side of the L-shaped base, and a nut assembly installed at the threaded position at one end of the threaded rod. The nut assembly is located at the center position inside the support platform and is fixedly connected to the support platform. One end of the threaded rod extends through to the outside of the C-shaped support frame and is fixed with a handle.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This quick assembly and positioning fixture for male and female grooves of composite bottom formwork floor slabs utilizes a structure that includes a C-shaped support frame, a cavity, several equally spaced double rollers in the vertical direction, and a screw adjustment mechanism. The C-shaped support frame is placed on one side of the fixed vertical floor slab, with the cavity in the C-shaped support frame aligned with the male groove of the fixed vertical floor slab. The vertical floor slab in the lifting state slowly moves down along the several double rollers in the cavity, continuously correcting the alignment of the male and female grooves of the two floor slabs. The operator adjusts the support plate through the screw adjustment mechanism, which limits the vertical floor slab in the lifting state and facilitates the alignment of the male and female grooves of the fixed and lifted floor slabs. The design of the C-shaped support frame ensures that the vertical floor slab in the lifting state... The slab receives stable support, reducing potential displacement and swaying during hoisting and movement. The cavity of the C-shaped support frame also ensures position control of the slab during hoisting and movement, preventing slab offset or rotation and laying the foundation for subsequent precise docking. Secondly, the double rollers have excellent rolling characteristics, reducing frictional resistance during slab movement and allowing the slab to slide smoothly along the predetermined trajectory, reducing positional errors caused by uneven friction or deviation, and facilitating precise alignment of the slab on the docking surface. Finally, the lead screw adjustment structure has high precision and controllability, allowing adjustments based on actual docking conditions to ensure optimal fit between the slab's docking surface and the male and female grooves, reducing errors caused by reliance on manual experience and improving the repeatability and consistency of docking.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figures 1-5 An embodiment of this utility model provides a quick assembly and positioning fixture for male and female grooves of composite bottom formwork floor slabs, including a C-shaped support frame 1, a cavity 2 provided inside the C-shaped support frame 1, and multiple double rollers 3 that are rotatably installed at equal intervals in the vertical direction on one side inner wall of the C-shaped support frame 1. A support platform 4 is slidably installed at the bottom of the C-shaped support frame 1, and an upwardly extending support plate 5 is integrally formed at the top of the support platform 4. A screw adjustment structure 6 for controlling the horizontal movement of the support platform 4 and the support plate 5 is also installed at the bottom of the C-shaped support frame 1.

[0019] The C-shaped support frame 1 is composed of two L-shaped double-layer frames 101 with mirror symmetry. The opposite ends of the two L-shaped double-layer frames 101 are bolted together. The C-shaped support frame 1 is composed of two mirror symmetrical L-shaped double-layer frames 101 bolted together, forming a stable and firm frame through the two L-shaped double-layer frames 101.

[0020] The C-shaped support frame 1 and the support platform 4 are both made of aluminum alloy components. The surface of the support plate 5 is provided with a hollow groove 501. The hollow groove 501 can reduce the structural weight of the support plate 5 and reduce the weight load of the fixture.

[0021] The bottom of the C-shaped support frame 1 is fixed with two square tracks extending along the X-axis. The bottom of the support platform 4 is equipped with a sliding groove that slides with the square tracks. The sliding groove and the square tracks improve the movement stability of the support platform 4.

[0022] The double roller 3 includes a convex shaft 303 rotatably mounted on the left and right inner walls of the C-shaped support frame 1, a square shaft 301 fixed between the opposite ends of the two convex shafts 303, and steel wheels 302 fitted at both ends of the surface of the square shaft 301. The steel wheels 302 are concentrically fitted on the square shaft 301. By utilizing the contact between the steel wheels 302 and the side of the floor slab, the rolling characteristics of the double roller 3 greatly reduce frictional resistance, making the floor slab smoother during slow movement and reducing the risk of deviation caused by uneven friction.

[0023] The screw adjustment structure 6 includes an L-shaped base 601 fixed to the bottom of the C-shaped support frame 1, a threaded rod 602 rotatably installed on one side of the outer wall of the L-shaped base 601, and a nut pair 603 installed at the thread position at one end of the threaded rod 602. The nut pair 603 is located at the center inside the support 4 and is fixedly connected to the support 4. One end of the threaded rod 602 extends through to the outside of the C-shaped support frame 1 and is fixed with a handle 604. The adjustment operation of the screw adjustment structure 6 is relatively simple, can quickly respond to changes on site, and avoids affecting the overall construction quality due to minor deviations.

[0024] Rotating the threaded rod 602 via the handle 604 causes the nut pair 603, the support platform 4, and the support plate 5 to move linearly horizontally. This allows the support plate 5 to contact the floor slab being lifted and control the position of the floor slab, ensuring that the floor slab can be properly aligned with the fixed floor slab before it is lowered.

[0025] In this embodiment, the operator first ensures that the C-shaped support frame 1 is placed on one side of the installed vertical floor slab, and that the cavity 2 is aligned with the male groove of the fixed floor slab, providing a stable foundation for subsequent connection. Next, the operator suspends the floor slab on the lifting equipment and slowly raises it to the predetermined height. During the lifting process, the guiding effect of the C-shaped support frame 1 and the cavity 2 ensures that the floor slab is basically correctly positioned vertically, and the vertical state is gradually adjusted. The operator uses the lead screw adjustment structure 6 to fine-tune the positions of the support platform 4 and the support plate 5, ensuring that the bottom female groove of the lifted floor slab is aligned with the male groove of the fixed floor slab. Basic alignment is achieved to avoid offset and misalignment, laying the foundation for precise docking later. After the bottom female groove of the lifted floor slab is aligned with the male groove of the fixed floor slab, the floor slab is slowly lowered. During the slow descent of the floor slab, multiple double rollers 3 in the vertical direction provide guidance. As the two floor slabs gradually approach the predetermined position and are aligned, the workers remove the C-shaped support frame 1, allowing the lifted floor slab to fall completely. After docking is completed, the workers conduct a final confirmation and fixation, checking whether the male and female grooves fit tightly and whether there are any deviations or looseness. If any problems are found, they are immediately fine-tuned or readjusted until the construction requirements are met.
