Description

Technical Field

[0001] This utility model specifically relates to a type of embedded part for fixing longitudinal reinforcement in beams, belonging to the field of building structure technology. Background Technology

[0002] A beam is a structural member supported by supports, bearing primarily lateral and shear forces, and exhibiting bending as its main deformation. Beams support the entire weight of the building's superstructure and roof, making them the most crucial part of the building's superstructure. Beams have different names depending on their specific location, detailed shape, and function. Most beams are oriented in the same direction as the building's cross-section, and generally have either circular or square cross-sectional shapes.

[0003] The beam's interior consists of multiple longitudinal reinforcement bars and several stirrups tied to them. In practice, the tying process mainly involves two methods:

[0004] The first method involves multiple workers assisting in binding: Based on the length of the longitudinal reinforcement bars in the beam, multiple workers are arranged in different positions to bind the stirrups simultaneously. During the binding process, the position of the longitudinal reinforcement bars in the beam is continuously adjusted and corrected to ultimately form the required beam shape. In this case, because it involves multiple people, although each worker's binding position needs to be operated according to the structural design requirements and specific construction operation specifications, the uniformity of manual operation will vary due to the workers' experience. This may create a hidden danger that the actual direction of the longitudinal reinforcement bars in the beam may be bent. The binding efficiency of this multi-person collaborative operation method is low and it is not conducive to the progress of construction.

[0005] The second method involves placing multiple longitudinal bars in the upper beam at supports or other supporting locations on the construction site. Workers tie the stirrups from one end, adding the longitudinal bars that need to be added below one by one during the tying process. This results in the longitudinal bars not being perpendicular to the stirrups in the initial tying stage. The positional shift caused by the tying method can only be gradually improved as more stirrups are added.

[0006] The root cause of the above situation is the inability to form the required shape of the longitudinal reinforcement bars in the multiple beams before binding the stirrups, and the lack of supporting tools that can meet the relevant specifications in the initial stage of binding. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, a fixed embedded part for longitudinal reinforcement in beams is provided to solve the above problems.

[0008] A type of embedded part for fixing longitudinal reinforcement in beams includes a central part and several longitudinal reinforcement grippers, wherein the several longitudinal reinforcement grippers are circumferentially arranged on the outer wall of the central part; each longitudinal reinforcement gripper includes a clamping connector, a telescopic arm and a connecting claw, one end of the clamping connector is detachably connected to the outer wall of the central part, the other end of the clamping connector is connected to one end of the telescopic arm, and the other end of the telescopic arm is hinged to a connecting claw.

[0009] As a preferred embodiment: an annular groove is machined on the outer wall of the central component along its circumference, the snap-fit ​​connector is slidably disposed in the annular groove, and insertion holes are machined on the outer walls on both sides of the annular groove.

[0010] As a preferred embodiment: each snap-fit ​​connector includes a main positioning block, two legs and two lugs. The lower end of the main positioning block is symmetrically provided with two legs. One of the two lugs is provided on the outer side of one leg, and the other of the two lugs is provided on the outer side of the other leg. The lugs are machined with positioning holes along their thickness direction. The main positioning block is slidably disposed in an annular groove.

[0011] As a preferred embodiment: the upper end of the main positioning block is connected to one end of the telescopic arm. The telescopic arm includes a connecting cylinder, a gripping part, a sliding rod, a screwing component, and two collars. The upper end of the main positioning block is set on the connecting cylinder. The connecting cylinder is machined with a slide rail along its length. The gripping part is slidably installed in the slide rail. The gripping part is detachably connected to the outer wall of the connecting cylinder. Each end of the gripping part is provided with a collar. A sliding rod is provided in the two collars. The sliding rod and the two collars are coaxially arranged. A screwing component is provided at the end of the sliding rod facing the longitudinal reinforcement of the beam.

[0012] As a preferred embodiment: the screw-on component is hinged with a connecting claw, the connecting claw including an elastic closure, a flexible belt, two rollers and two buckles, the screw-on component is hinged with an elastic closure, each side of the elastic closure is provided with a buckle, one end of the flexible belt is provided on one of the two buckles and the other end of the flexible belt is provided on the other of the two buckles, and each end of the elastic closure is hinged with a roller.

[0013] As a preferred option, the grip area is machined with stripes to increase hand grip friction.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model can achieve multiple usage modes through the cooperation of the central component and several longitudinal reinforcement grab arms. It can be used individually or in combination. When large-span longitudinal reinforcement is involved in the construction site, this utility model can be used in an emergency to achieve local circumferential support, so as to avoid the longitudinal reinforcement being concave and causing irregular placement, which would affect the quality of the subsequent cast beam.

[0016] 2. When multiple of these utility models are used in combination, they can achieve a circumferential support effect for the entire beam by multi-point placement. They can fix the encircling shape of multiple longitudinal bars in the beam before binding the stirrups, which can not only ensure the accurate position of the longitudinal bars in the beam, but also make the arrangement of the stirrups more in line with the specifications when binding. The operation of binding the stirrups is standardized and uniform. Furthermore, by increasing the number of longitudinal bar grab arms, the usage needs of different numbers of longitudinal bars in the beam can be met.

[0017] 3. The length of the longitudinal rib grab arm in this utility model can be adjusted locally as needed, and can meet the structural requirements of beams of different shapes according to specific design requirements, which is conducive to improving the uniform processing of beam standardization and improving the quality of beams.

Detailed Implementation

[0034] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0035] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 This embodiment describes a beam longitudinal reinforcement shaping embedded part comprising a central part 1 and a plurality of longitudinal reinforcement grippers 2, wherein the plurality of longitudinal reinforcement grippers 2 are circumferentially arranged on the outer wall of the central part 1; each longitudinal reinforcement gripper 2 includes a clamping connector 2-1, a telescopic arm 2-2 and a connecting claw 2-3, one end of the clamping connector 2-1 is arranged on the outer wall of the central part 1, one end of the clamping connector 2-1 is arranged at one end of the telescopic arm 2-2, and the other end of the telescopic arm 2-2 is hinged to the connecting claw 2-3.

[0036] Several longitudinal reinforcement grab arms 2 are circumferentially arranged on the outer wall of the central component 1. The position of each longitudinal reinforcement grab arm 2 can be freely adjusted by the snap joint 2-1, and the length of each longitudinal reinforcement grab arm 2 can be adjusted by the telescopic arm 2-2. Ultimately, this utility model can meet the needs of the support structure required for the longitudinal reinforcement in the beam to be enclosed into different shapes.

[0037] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. An annular groove 1-1 is machined on the outer wall of the central component 1 along its circumferential direction. The snap-fit ​​connector 2-1 is slidably disposed in the annular groove 1-1. Insertion holes 1-2 are machined on the outer walls on both sides of the annular groove 1-1. The longitudinal rib grab arm 2 is disposed on the central component 1 in a detachable connection manner through the insertion holes 1-2.

[0038] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. Each snap-fit ​​connector 2-1 includes a main positioning block 2-1-1, two legs 4 and two lugs 2-1-3. The lower end of the main positioning block 2-1-1 is symmetrically provided with two legs 4. Preferably, the legs 4 are L-shaped. One of the two lugs 2-1-3 is provided on the outer side of one leg 4, and the other of the two lugs 2-1-3 is provided on the outer side of the other leg 4. The lugs 2-1-3 are flat square pieces. The lugs 2-1-3 are machined with positioning holes 2-1-3-1 along their thickness direction. The positioning holes 2-1-3-1 are preferably threaded holes. The main positioning block 2-1-1 is slidably disposed in the annular groove 1-1.

[0039] The two legs 4 of the main positioning block 2-1-1 are elastic elements. Since the legs 4 are L-shaped, they unfold after being inserted into the annular slide groove 1-1 by pinching. Since the annular slide groove 1-1 is a T-shaped groove, the lower ends of the two legs 4 are respectively stuck in the two side grooves in the annular slide groove 1-1, realizing the sliding connection of the snap-fit ​​connector 2-1 in the annular slide groove 1-1. Then, the snap-fit ​​connector 2-1 is connected to the positioning hole 2-1-3-1 and the insertion hole 1-2 in sequence by screwing, thus fixing the position of the snap-fit ​​connector 2-1 on the center piece 1.

[0040] Specific Implementation Method Four: This implementation method further defines Specific Implementation Methods One, Two, or Three. The upper end of the main positioning block 2-1-1 is located at one end of the telescopic arm 2-2. The telescopic arm 2-2 includes a connecting cylinder 2-2-1, a gripping part 2-2-2, a sliding rod 2-2-3, a screwing part 2-2-4, and two collars 2-2-5. The upper end of the main positioning block 2-1-1 is located on the connecting cylinder 2-2-1. The connecting cylinder 2-2-1 has a slide rail 2-2-1-1 machined along its length. The gripping part 2-2-2 is slidably installed in the slide rail 2-2-1-1. The gripping part 2-2-2 is detachably connected. On the outer wall of the connecting cylinder 2-2-1, the gripping part 2-2-2 is preferably set on the outer wall of the connecting cylinder 2-2-1 by screws. Each end of the gripping part 2-2-2 is provided with a collar 2-2-5. A sliding rod 2-2-3 is provided inside the two collars 2-2-5. Preferably, the collars 2-2-5 and the sliding rod 2-2-3 are threadedly connected. The sliding rod 2-2-3 and the two collars 2-2-5 are coaxially arranged. One end of the sliding rod 2-2-3 is provided with a screwing part 2-2-4. The screwing part 2-2-4 facilitates manual operation of the sliding rod 2-2-3 and provides a stable force structure for quick disassembly and installation.

[0041] Furthermore, the grip portion 2-2-2 is machined with stripes to increase hand grip friction.

[0042] Remove the screws to allow the grip 2-2-2 to slide quickly within the slide rail 2-2-1-1. When the grip 2-2-2 slides quickly, it drives the slide rod 2-2-3 to quickly extend or retract via the collar 2-2-5. Preferably, the collar 2-2-5 is threadedly connected to the slide rod 2-2-3. By rotating the slide rod 2-2-3 with the screw 2-2-4, the slide rod 2-2-3 can be extended or retracted relative to the collar 2-2-5. Since it is a threaded connection, the extension or retraction distance of the slide rod 2-2-3 can be finely adjusted.

[0043] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Methods 1, 2, 3, or 4. A connecting claw 2-3 is hinged to the screwing component 2-2-4. The connecting claw 2-3 includes an elastic closing component 2-3-1, a flexible belt 2-3-2, two rollers 2-3-3, and two buckles 2-3-4. The elastic closing component 2-3-1 is hinged to the screwing component 2-2-4. Each side of the elastic closing component 2-3-1 is provided with a buckle 2-3-4. One end of the flexible belt 2-3-2 is provided on one buckle 2-3-4, and the other end of the flexible belt 2-3-2 is provided on the other buckle 2-3-4. The flexible belt 2-3-2 can be removed from the buckle 2-3-4 to achieve replacement of the flexible belt 2-3-2. Each roller 2-3-3 is hinged to each of the two ends of the elastic closing component 2-3-1.

[0044] When it is necessary to place the longitudinal reinforcement 3 inside the beam on the connecting claw 2-3, simply place the longitudinal reinforcement 3 inside the beam between the two rollers 2-3-3 and press it down towards the flexible belt 2-3-2, so that the longitudinal reinforcement 3 inside the beam enters the space enclosed by the two rollers 2-3-3 and the flexible belt 2-3-2. The position of the longitudinal reinforcement 3 inside the beam is fixed by the compression of the longitudinal reinforcement 3 inside the beam by the two rollers 2-3-3 and the flexible belt 2-3-2.

[0045] Specific Implementation Method Six: Combination Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 This embodiment is a further limitation of the first specific embodiment. The outer wall of the center component 1 is machined with an annular groove 1-1 along its circumference. The inner wall of the annular groove 1-1 is machined with a plurality of insertion holes 1-2 along its circumference. The insertion holes 1-2 and the snap-fit ​​connector 2-1 are inserted and fitted together. The snap-fit ​​connector 2-1 is detachably connected to the annular groove 1-1 and the insertion holes 1-2 respectively. Preferably, the central angle formed by two adjacent insertion holes 1-2 is 30°.

[0046] Specific Implementation Method Seven: This implementation method is a further limitation of Specific Implementation Method Six. Each snap-fit ​​connector 2-1 includes a main positioning block 2-1-1, a plug rod 2-1-4, a lever 2-1-5, a first elastic lever 2-1-6, two lugs 2-1-3, two second elastic levers 2-1-7, and two snap-fit ​​pieces 2-1-2. A cavity 2-1-1-1 is machined inside the main positioning block 2-1-1. One end of the plug rod 2-1-4 passes through the cavity 2-1-1-1 from the lower end of the main positioning block 2-1-1, and the other end of the plug rod 2-1-4 is inserted into the insertion hole 1-2. The lever 2-1-5 passes through the cavity 2-1-1-1 from the side of the main positioning block 2-1-1. One end of the plug rod 2-1-4 is positioned on the lever 2-1-6. At one end of -1-5, a first elastic lever 2-1-6 is provided inside the cavity 2-1-1-1. One end of the first elastic lever 2-1-6 contacts the side wall of the lever 2-1-5. The lower end of the main positioning block 2-1-1 is machined with two T-shaped grooves 2-1-1-2. Each T-shaped groove 2-1-1-2 is provided with a second elastic lever 2-1-7. Each second elastic lever 2-1-7 contacts each locking piece 2-1-2. Each locking piece 2-1-2 is slidably disposed in each T-shaped groove 2-1-1-2. Each locking piece 2-1-2 is provided with a support ear 2-1-3 on the outside. The two T-shaped grooves 2-1-1-2 are arranged opposite to each other. The two locking pieces 2-1-2 are slidably disposed in the annular groove 1-1.

[0047] By pinching the two lugs 2-1-3, each clip 2-1-2 is pressed against the second elastic lever 2-1-7, causing the two clips 2-1-2 to retract. Then, the two clips 2-1-2 are inserted into the annular groove 1-1. The two lugs 2-1-3 are released, so that the two extended clips 2-1-2 are locked in the annular groove 1-1 and will not come off. The clip 2-1 slides along the annular groove 1-1. When it passes the insertion hole 1-2, the insertion rod 2-1-4 is inserted into the insertion hole 1-2, thereby limiting the position of the longitudinal rib grab arm 2. The insertion rod 2-1-4 can be disengaged from the insertion hole 1-2 by pushing the lever 2-1-5, so that the position of the longitudinal rib grab arm 2 can be adjusted directly in the annular groove 1-1.

[0048] Working principle:

[0049] Based on actual usage requirements, the number of longitudinal rib grab arms 2 and the predetermined shape after unfolding are determined. Then, the corresponding number of longitudinal rib grab arms 2 are connected one by one to the central component 1. The installation process of each longitudinal rib grab arm 2 is to move along the circumference of the annular groove 1-1 through the snap-fit ​​connector 2-1 until the snap-fit ​​connector 2-1 is adjusted to the designated position. This process is repeated to complete the installation of all longitudinal rib grab arms 2. Then, according to design requirements, the position to be reached of each telescopic arm 2-2 is adjusted one by one. The telescopic length of the telescopic arm 2-2 is adjusted according to the position requirements of the connecting claw 2-3. Finally, in this utility model, multiple connecting claws 2-3 cooperate and are located in their respective predetermined positions. The shape formed by the predetermined positions of multiple connecting claws 2-3 is the shape of the transverse section of the beam. Push to complete the placement process of multiple longitudinal reinforcement anchors in the beams. The spacing between two adjacent longitudinal reinforcement anchors should meet the structural design and construction requirements. Multiple longitudinal reinforcement anchors form a longitudinally parallel limiting structure. Install a predetermined number of longitudinal reinforcement bars 3 on the multiple longitudinal reinforcement anchors, that is, insert one longitudinal reinforcement bar 3 longitudinally through multiple connecting claws 2-3 at the same straight line position in the multiple longitudinal reinforcement anchors. Repeat this process to limit the position of multiple longitudinal reinforcement bars 3. The multiple longitudinal reinforcement bars 3 finally form a frame of the required shape. At this time, when the stirrups 5 are tied, there will be no local bending of the longitudinal reinforcement bars 3 or incorrect tying position of the stirrups 5. Finally, tie a predetermined number of stirrups 5 on the multiple longitudinal reinforcement bars 3.
