Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a beam reinforcement forming and regulating device for composite slab construction. Background Art

[0002] Beam components are important structures in building structures, and their construction quality determines the safety and stability of the structure. According to relevant specifications, the length of the structural plate reinforcement anchored in the beam reinforcement should be no less than half of the beam width, that is, at least 1 / 2 of the beam width.

[0003] However, during the construction of the composite slab, there are two methods to ensure that the beard reinforcement of the composite slab extends into the beam by 1 / 2 of the beam width. One method is to place the composite slab first and then tie the beam reinforcement. However, because the beam reinforcement cannot be fixed, it will fall down, making it difficult to implement on-site. The other method is to tie the beam reinforcement first and then place the composite slab. This is feasible, but when constructing according to this procedure, there are the following problems:

[0004] When inserting the reinforcement of the composite plate into the beam, the beam reinforcement has to be lifted up and the composite plate reinforcement has to be bent. After the composite plate is put into place, the beam reinforcement is dropped down and the bent reinforcement is bent back to its original shape. This process not only increases the difficulty of construction, but also easily weakens the tensile performance of the steel bars, resulting in a huge safety hazard to the structural safety.

[0005] To address this problem, a beam forming control device for composite slab construction was designed and invented, which enables the beam to be formed before the beam reinforcement is tied, thereby ensuring that the beam and slab reinforcement are not damaged by excessive bending. Utility Model Content

[0006] The purpose of the present invention is to at least solve one of the technical defects described in the background technology.

[0007] To this end, one purpose of the present invention is to propose a beam reinforcement forming and control device for composite slab construction, aiming to solve the problem in the prior art that when the beard reinforcement of the composite slab is deeply inserted into the beam, the construction is difficult and the beam and slab reinforcement is easily damaged.

[0008] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the utility model provides a beam reinforcement forming and control device for composite slab construction, comprising an axis mother tube and two telescopic shafts, the two telescopic shafts being telescopically connected inside the two ends of the axis mother tube, the ends of the telescopic shafts being fixedly connected with support hooks and hooks, the support hooks extending along the radial direction of the telescopic shafts, and the hooks being perpendicular to the telescopic shafts.

[0009] Preferably, any of the above schemes is provided with an oil filling and exhaust hole in the middle of the shaft mother cylinder. The hole can be used for regular oil filling and maintenance of the device, and can also eliminate the internal pressure during the twisting of the shaft wire cylinder.

[0010] Preferably, from any of the above schemes, the two telescopic shafts are threadedly connected to the interior of the two ends of the shaft mother cylinder, and the outer surface of the shaft mother cylinder is provided with anti-slip protrusions, which facilitate twisting of the shaft mother cylinder.

[0011] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0012] 1. The device is hung on the stirrups of the beam skeleton through the hook. The shaft mother tube and the telescopic shaft support the steel bars on the upper surface of the beam skeleton, and the support hook supports the angle bars on the upper surface of the beam skeleton, so that the beam skeleton is formed. During the construction of the composite slab, the telescopic shaft is retracted to make the angle bars avoid the beard bars of the composite slab. After the beard bars of the composite slab are inserted into the beam skeleton, the telescopic shaft is extended to adjust the position of the angle bars. Then, the steel bars on the upper surface of the beam skeleton are tied and fixed, and the device can be removed, thereby reducing the construction difficulty and avoiding the problem of bending and damage of the beam and slab bars.

[0013] 2. By setting the oil filling and exhaust holes, it is convenient to inject lubricating maintenance oil into the interior of the shaft mother barrel, thereby avoiding rust between the inner wall of the shaft mother barrel and the telescopic shaft, which makes it difficult for the telescopic shaft to be extended and retracted inside the shaft mother barrel. When the telescopic shaft is extended and retracted inside the shaft mother barrel, the oil filling and exhaust holes can exhaust or take in air, thereby eliminating the pressure inside the shaft mother barrel, making the extension and retraction of the telescopic shaft smoother.

[0014] 3. When the telescopic shaft and the shaft mother tube are telescopically connected by a threaded connection, the setting of the anti-slip convex point facilitates the twisting of the shaft mother tube, thereby facilitating operation.

[0015] Additional aspects and advantages of the present invention will be given in part in the following description and in part will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the description of the embodiments in conjunction with the following drawings, in which:

[0018] Among them: 1. Shaft mother cylinder, 2. Telescopic shaft, 3. Support hook, 4. Hook, 5. Oil filling and exhaust hole, 6. Anti-slip bumps. DETAILED DESCRIPTION

[0019] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0021] The utility model provides a beam reinforcement forming control device for composite slab construction.

[0022] Example 1:

[0023] like Figure 1 As shown, it includes a shaft mother cylinder 1 and two telescopic shafts 2, the two telescopic shafts 2 can be telescopically connected to the inside of the two ends of the shaft mother cylinder 1, and the ends of the telescopic shaft 2 are fixedly connected with a hook 3 and a hook 4. By telescoping and adjusting the telescopic shaft 2 in the shaft mother cylinder 1, the spacing between the hooks 3 at the ends of the two telescopic shafts 2 can be adjusted. The hook 3 extends along the ray direction of the telescopic shaft 2, and the hook 4 is perpendicular to the telescopic shaft 2. The hook directions of the hooks 3 and the hook 4 are perpendicular to each other. An oil filling and exhaust hole 5 is provided in the middle part of the shaft mother cylinder 1, and lubricating oil can be injected into the interior of the shaft mother cylinder 1 through the oil filling and exhaust hole 5, thereby ensuring that the telescopic shaft 2 can be smoothly telescopically adjusted inside the shaft mother cylinder 1. During use, when the telescopic shaft 2 slides and adjusts inside the shaft mother cylinder 1, the air in the shaft mother cylinder 1 can be discharged through the oil filling and exhaust hole 5, or the external air enters the shaft mother cylinder 1 through the oil filling and exhaust hole 5, thereby balancing the internal air pressure of the shaft mother cylinder 1 with the external air pressure, thereby ensuring the smooth movement of the telescopic shaft 2 inside the shaft mother cylinder 1.

[0024] The working principle of this embodiment is as follows: when tying the steel bar skeleton in the beam, the beam bars and beam stirrups on the lower layer and both sides of the skeleton are tied and fixed together, while the steel bars on the upper layer of the skeleton are temporarily not tied. The steel bars on the upper layer are placed on top of the shaft mother tube 1 and the telescopic shaft 2, and the angle bars on both sides of the upper layer of the skeleton are placed in the support hooks 3. Then, the shaft mother tube 1 and the two telescopic shafts 2 are hung on the beam stirrups by the hooks 4. By arranging multiple such devices in the skeleton, the steel bars on the upper layer of the skeleton are supported and positioned, so that the skeleton is formed, and then the formed skeleton is dropped into the beam mold.

[0025] During the construction of the composite slab, the telescopic shaft 2 is retracted into the shaft mother tube 1, so that the steel bars on the upper surface of the beam skeleton are gathered together, and the corner bars on both sides of the upper surface of the beam skeleton are moved closer to the middle. Therefore, the side of the skeleton avoids a gap for the insertion of the beard bars of the composite slab. After the beard bars of the composite slab are inserted into the interior of the beam skeleton, the telescopic shaft 2 is extended from the shaft mother tube 1, so that the corner bars on both sides of the upper surface of the beam skeleton are located at the corners of the beam stirrups. Then, after the steel bars on the upper surface of the beam skeleton and the beam stirrups are tied and fixed together, the device can be disassembled and then the concrete pouring construction can be carried out.

[0026] Example 2:

[0027] like Figure 1 As shown, on the basis of Example 1, the inner walls of both ends of the shaft mother cylinder 1 are provided with thread grooves, and the outer surface of the telescopic shaft 2 is provided with threads. The two telescopic shafts 2 are threadedly connected to the inside of the two ends of the shaft mother cylinder 1. By rotating the shaft mother cylinder 1, the telescopic shafts 2 at both ends can be telescopically adjusted, thereby achieving the purpose of telescopic connection between the telescopic shaft 2 and the shaft mother cylinder 1. The outer surface of the shaft mother cylinder 1 is provided with anti-slip bumps 6, which increase the friction with the hand during the rotation of the shaft mother cylinder 1, thereby facilitating the rotation of the shaft mother cylinder 1.

[0028] The working principle of this embodiment is different from that of the first embodiment in that: when in use, the telescopic shafts 2 at both ends can be synchronously extended or shortened by rotating the shaft mother cylinder 1, thereby achieving the purpose of retracting and pulling the upper surface steel bars of the expansion beam skeleton.
