Description

Technical Field

[0001] The present invention relates to the technical field of wharf engineering construction, and more specifically, to a wharf engineering overwater crossbeam reinforcement binding and positioning device and a construction method thereof. Background Art

[0002] In the traditional dock project, due to the limitation of the on-site construction platform, the steel bar binding of the water beam is usually done by manually drawing the steel bar position on the bottom mold with a stone pencil, laying the bottom concrete protective layer pad, and placing and installing the stirrups and main bars. This is time-consuming and labor-intensive, and the work efficiency is very low. In addition, the overall axis is prone to deviation, resulting in uneven control of the spacing of the stirrups. Especially when the spacing of the stirrups is dense, it is easy to cause bubbles, honeycombs, holes, etc. on the surface of the beam concrete. In severe cases, it affects the uneven force of the beam as a whole, causing quality accidents. At the same time, the overall tilt of the steel bar is prone to occur during the binding process, requiring secondary manual and crane adjustments, which not only increases the cost expenditure but also increases the probability of safety accidents such as injuries to operators and machinery and facilities. In addition, since the amount of steel bars used in the dock beam is large and it is independent of the water and presents an island shape, if the steel bars are hoisted on water after being tied on land, large-scale ship machinery and equipment are required to cooperate. During the construction process, if the operation and command are improper, there is a risk of collision, resulting in overall deformation of the steel bars, and the quality of the project and construction safety are difficult to guarantee.

[0003] In order to solve the adverse effects of traditional binding technology, patent CN215033214U discloses a prefabricated crossbeam reinforcement binding support device, including at least two support frames arranged at intervals in front and back; each support frame includes: at least two brackets, the two brackets are arranged symmetrically on the left and right, and the lower ends of the two brackets are connected by a cross bar; and at least two groups of main beam reinforcement positioning rod groups, the two groups of main beam reinforcement positioning rod groups are spaced apart from each other and are installed between the upper ends of the two brackets in a detachable manner, each group of the main beam reinforcement positioning rod group includes at least one first positioning rod, and the first positioning rod is provided with at least two spaced reinforcement positioning grooves along its axial direction, wherein each first positioning rod can slide up and down along the two brackets and be fixed by a fixing device. Although the support frame in this device can adjust the distance between the two positioning rods according to actual needs, thereby adjusting the distance between the main beam reinforcements, it has a wide range of applications and strong practicality; but the device is also unable to perform equal spacing positioning control on the stirrups, and bubbles and honeycombs are likely to appear on the surface of the cross beam concrete due to the dense spacing of the stirrups, which affects the overall uneven force of the cross beam. In addition, after completing the binding of all the crossbeam steel bars, the device needs to be moved with the help of other equipment, which may easily cause collision accidents and cause deformation of the steel bars, and the quality of the steel bars and construction safety cannot be guaranteed.

[0004] Therefore, how to design a device with simple structure, easy installation and convenient transportation, which can not only effectively assist in the binding of the steel bars of the water beam of the dock project, but also effectively improve the safety of on-site water operations while improving the qualified rate and construction efficiency of the steel bar binding construction quality, has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0042] Example 1

[0043] This embodiment provides a structural composition of a device for tying and positioning steel bars of an overwater beam of a dock project.

[0044] Please refer to the attached Figure 1-3 , Figure 1 This is a front view of a device for tying and positioning steel bars for a horizontal beam on water in a wharf project provided by the present invention. Figure 2This is a side view of a device for tying and positioning steel bars for a horizontal beam on water in a wharf project provided by the present invention. Figure 3 The present invention is a schematic diagram of the structural composition of a device for tying and positioning steel bars of a horizontal beam on water in a wharf project.

[0045] A device for tying and positioning steel bars of a horizontal beam on water for a dock project, comprising an I-beam 1, a composite plastic plate bottom mold 2, a bottom support 3, a bottom steel bar point rod 4, a latch 5, a side steel bar point rod 6, a clamping device 7 and a steel bar positioning buckle 9;

[0046] A plurality of I-beams 1 are placed at equal intervals below the composite plastic board bottom mold 2; a plurality of bottom supports 3 are placed at equal intervals above the composite plastic board bottom mold 2; the bottom steel bar point rods 4 are placed on the bottom supports 3, and are fixedly connected to the composite plastic board bottom mold 2 via latches 5; the side steel bar point rods 6 are arranged at both ends of the bottom steel bar point rods 4, and are fixedly connected via a plurality of screws; the clamping device 7 is arranged on the side steel bar point rods 6; the bottom steel bar point rods 4 are used to position and bind the bottom transverse beam stirrups 8; the clamping device 7 is used to position and bind the vertical beam stirrups 8; and the top transverse beam stirrups 8 are connected in pairs via steel bar positioning buckles 9.

[0047] Furthermore, the I-beam 1 has high rigidity, stable pressure bearing capacity, and uniform overall force; and by arranging the I-beam 1 at intervals, the I-beam's own weight can be effectively reduced.

[0048] Furthermore, the composite plastic board bottom mold 2 is easy to cut, has a light weight, is stronger than bamboo plywood, is not easily deformed, and has good water resistance and corrosion resistance.

[0049] Furthermore, the bottom support 3 is formed by welding a steel pipe and an iron plate; the specifications and dimensions of the steel pipe and the iron plate should be calculated based on the upper load during the beam reinforcement binding process.

[0050] Furthermore, the bottom support 3 is located at the lower part of the bottom steel bar point rod 4, and its cross section is consistent with the bottom steel bar point rod 4 in the width direction, and is connected in line and surface, which is easy to install and remove.

[0051] Furthermore, the placement positions of the multiple bottom supports 3 on the composite plastic plate bottom mold 2 are consistent with the placement positions of the multiple I-beams 1 under the composite plastic plate bottom mold 2 to ensure stable load force.

[0052] Furthermore, the bottom steel bar point rod 4 is composed of multiple sections of square steel connected by multiple screws, which is easy to disassemble. The specifications and dimensions of the square steel should be calculated based on the upper load during the crossbeam steel bar binding process.

[0053] Furthermore, a plurality of positioning screws 4 a are anchored on the square steel, and the spacing between the positioning screws 4 a is determined according to the diameter of the crossbeam stirrups 8 .

[0054] Furthermore, the pin 5 is welded by a round steel and a nut; the pin 5 is located at the nodes of the bottom steel bar point rod 4 and the side steel bar point rod 6, and is set at four places in total; the pin 5 passes through the bottom steel bar point rod 4 and the composite plastic board bottom mold 2, and is set close to one side of the I-beam 1.

[0055] Furthermore, the material of the side reinforcement point rod 6 is square steel, and reserved holes are arranged in the middle and upper parts.

[0056] Furthermore, the clamping device 7 is provided in plurality, and is respectively arranged at the middle and upper parts of the side reinforcement point rod 6, so that the clamping of the crossbeam stirrups is made tighter and more stable, and is not easily affected by wind and waves.

[0057] Furthermore, as attached Figure 5 As shown, Figure 5 It is a schematic diagram of a steel bar positioning buckle in a water beam steel bar binding and positioning device for a dock project provided by the present invention. The top steel bar positioning buckle 9 is a flat steel with slots at both ends. The size of the slot is consistent with the diameter of the beam stirrup 8, and is used to clamp the tops of two adjacent beam stirrups 8; the top steel bar positioning buckle 9 can effectively ensure that the spacing between the top transverse beam stirrups 8 is consistent, and plays a stabilizing role.

[0058] Furthermore, the top steel bar positioning buckles 9 are cross-installed between adjacent cross beam stirrups 8, so that the overall stability of the upper portion of the cross beam stirrups 8 can be effectively guaranteed.

[0059] Furthermore, since the above-water crossbeam reinforcement binding and positioning device for a dock project provided in this embodiment is actually used in seaport projects or isolated islands and is susceptible to corrosion from seawater, all components in the device will be subjected to anti-corrosion protection on their surfaces before use (by adopting measures such as painting with anti-corrosion paint) to ensure their own rigidity and strength, and thus ensure the stability of their bearing capacity.

[0060] Example 2

[0061] Based on the above-mentioned embodiment 1, this embodiment provides a structural composition and installation method of a clamping device in a steel bar binding and positioning device for an overwater beam of a wharf project.

[0062] Please refer to the attached Figure 4 , Figure 4 The present invention is a top view of a clamping device in a steel bar binding and positioning device for an overwater crossbeam of a wharf project.

[0063] The clamping device 7 includes a left nut 7a, a screw rod 7b, a right nut 7c and a steel bar holder 7d. The left nut 7a and the right nut 7c are both sleeved on the screw rod 7b, and the steel bar holder 7d is arranged at one end of the screw rod 7b.

[0064] Furthermore, the steel bar holder 7d is welded from left to right in sequence by a nut and a hinge, and a spring is also provided at an appropriate position on the left upper end of the hinge (holes can be drilled there and both ends of the spring can be screwed directly into the holes with a buffer ring, or both ends of the spring can be directly welded to the hinge), so that the steel bar holder 7d has a better clamping force, so as to better clamp the crossbeam stirrups 8.

[0065] Furthermore, the provision of the nut is to facilitate timely replacement of the steel bar holder 7d when the spring is damaged or the elastic force is insufficient due to improper use, which is beneficial to continuous operation of on-site construction.

[0066] Furthermore, the hinge is made of a steel plate with a rough surface to increase friction, thereby better clamping the crossbeam stirrups 8.

[0067] The installation method of the clamping device 7 specifically includes the following steps:

[0068] Step 1: After the side reinforcement point rod 6 is installed, insert the screw 7b into the reserved hole in the middle and upper part;

[0069] Step 2: Install the right nut 7c and the steel bar holder 7d in sequence, and clamp the crossbeam stirrup 8 with the steel bar holder 7d;

[0070] Step 3: Adjust the position of the right nut 7c and install the left nut 7a.

[0071] Furthermore, when adjusting the position of the right nut 7c in the step three, the side steel bar point rod 6 is used as a reference, and compared with the center distance of the first pair of positioning screws 4a on the bottom steel bar point rod 4 (when installing the bottom steel bar point rod 4, its position is determined according to the requirements of the steel bar construction drawing), that is, the center position of the lateral installation of the first row of crossbeam stirrups 8, the right nut 7c is tightened toward the side steel bar point rod 6, and then the left nut 7a is screwed on and tightened, so that the entire clamping device 7 is fixed on the side steel bar point rod 6.

[0072] Example 3

[0073] Based on the above-mentioned Embodiment 1 and Embodiment 2, this embodiment provides a construction method of a device for tying and positioning a steel bar of a horizontal beam on water in a wharf project, which specifically includes the following steps:

[0074] S1: After the piles are sunk to form a beam support system, an I-beam 1 is installed, a composite plastic board bottom formwork 2 is laid, and a bottom support pad 3 is placed;

[0075] S2: Install the bottom steel bar point rod 4 and the side steel bar point rod 6, and install the latch 5;

[0076] S3: while installing the clamping device 7, simultaneously install the first crossbeam stirrup 8 from both ends of the crossbeam, and adjust the position of the clamping device 7 so that it clamps the first crossbeam stirrup 8;

[0077] S4: Using the first crossbeam stirrup 8 as a reference, synchronously install the second crossbeam stirrup 8 and install the top steel bar positioning buckle 9;

[0078] S5: Repeat S4 to install all the beam stirrups 8;

[0079] S6: Install the main reinforcement of the beam 10;

[0080] S7: Install the bottom and outer protective layer pads of the beam reinforcement, and release the clamping device 7 and the top reinforcement positioning buckle 9;

[0081] S8: Remove the pin 5, the bottom support 3, the side reinforcement point rod 6, and the bottom reinforcement point rod 4 in sequence, and the crossbeam reinforcement binding construction is completed.

[0082] Furthermore, when the first crossbeam stirrup 8 is installed in S3, its bottom needs to be installed in the first pair of positioning screws 4a of the bottom steel bar point rod 4, and then the clamping device 7 is used to clamp the vertical crossbeam stirrups 8 on both sides.

[0083] Furthermore, when adjusting the position of the clamping device 7 in S3 so that it clamps the first beam stirrup 8, it is necessary to ensure that the position and horizontality of the first beam stirrup 8 meet the requirements by adjusting the position of the clamping device 7, so as to serve as the installation positioning reference for the subsequent beam stirrups 8.

[0084] Furthermore, when removing the bottom support 3 in S8, the lever principle is used to prop up the beam stirrups 8 with a crowbar to remove the bottom support 3, so that the bound beam reinforcement falls as a whole on the bottom concrete protective layer pad.

[0085] The above are only preferred embodiments of the present application, which do not limit the protection scope of the present application. For those skilled in the art, the present application may have various modifications and changes.
