Description

Technical Field

[0001] The invention relates to the technical field of I-beam cross diaphragms, and in particular to a template locking device and a construction method for an I-beam cross diaphragm. Background Art

[0002] The diaphragm plays an important role in maintaining the lateral stability of the bridge, ensuring that the main beams are connected as a whole, adjusting the uneven loads of the beams, etc. in the open cross-section beam bridges such as I-beams, and in improving the torsional rigidity of the beam. At the same time, the diaphragm can also connect the main beams as a whole in the horizontal direction to bear the horizontal load, improve the torsional stability of the beam, increase the lateral rigidity of the cross section, and limit the distortion stress. It is an important part of making the bridge an integral spatial structure.

[0003] In previous construction projects, I-beam diaphragms needed to be cast a second time. However, the secondary casting was prone to quality problems such as leakage. When concrete overflowed from the diaphragm formwork along the steel bars, the overflowed concrete would harden on the locking device, making it difficult to remove the locking device. If it was forcibly removed, it would not only damage the formwork and locking device, but would also be time-consuming and labor-intensive, delaying the construction progress.

[0036] refer to Figures 1 to 5 The template locking device and the construction method of the I-beam diaphragm according to the embodiment of the present invention are described.

[0037] like Figures 1 to 5As shown, the template locking device according to the first embodiment of the present invention includes a first locking mechanism 100, the first locking mechanism 100 includes a first concrete blocking member 110, the first concrete blocking member 110 has a first blocking cavity 111, the input end of the first blocking cavity 111 is connected to the interior of the diaphragm template 30, a plurality of first through holes 112 are opened on the cavity wall of the first blocking cavity 111, and the plurality of first through holes 112 are evenly arranged along the cavity wall of the first blocking cavity 111. When the concrete in the diaphragm template 30 overflows to the first blocking cavity 111 along the extension path of the steel bar 10, the concrete overflows outward from the first through holes 112; Second locking mechanism 200, the second locking mechanism 200 includes a second concrete barrier 210, the second concrete barrier 210 has a second barrier cavity 211, the volume of the first barrier cavity 111 is greater than the volume of the second barrier cavity 211, the input end of the second barrier cavity 211 is connected to the interior of the diaphragm template 30, a plurality of second through holes 212 are opened on the cavity wall of the second barrier cavity 211, and the plurality of second through holes 212 are evenly arranged along the cavity wall of the second barrier cavity 211. When the concrete in the diaphragm template 30 overflows to the second barrier cavity 211 along the extension path of the steel bar 10, the concrete overflows outward from the second through holes 212.

[0038] like Figure 1 As shown, the first concrete barrier 110 is a cylindrical structure, wherein the first concrete barrier 110 has a first barrier cavity 111, the first barrier cavity 111 is located at the rear of the first concrete barrier 110, and is connected to the interior of the diaphragm template 30, and the first barrier cavity 111 is evenly provided with a plurality of first through holes 112 along the circumferential direction. Similarly, the second concrete barrier 210 is a cylindrical structure, wherein the second concrete barrier 210 has a second barrier cavity 211, the second barrier cavity 211 is located at the rear of the second concrete barrier 210, and is connected to the interior of the diaphragm template 30, and the second barrier cavity 211 is evenly provided with a plurality of second through holes 212 along the circumferential direction. When concrete overflows from the connection between the diaphragm formwork 30 and the steel bar 10, the concrete flows into the first barrier cavity 111 and the second barrier cavity 211 along the extension direction of the steel bar 10, and then overflows through the first through hole 112 opened on the peripheral wall of the first barrier cavity 111 and the second through hole 212 opened on the peripheral wall of the second barrier cavity 211, thereby preventing the concrete from continuing to leak out along the extension direction of the steel bar 10, thereby achieving concrete blocking, avoiding damage to components caused by being covered and solidified by concrete, ensuring the free movement and removal of components, and improving construction efficiency and reducing construction costs while ensuring construction quality.

[0039] Furthermore, if Figures 2 to 4As shown, the radial cross-sectional areas of the first barrier cavity 111 and the second barrier cavity 211 are the same, but the axial length of the first barrier cavity 111 is greater than the axial length of the second barrier cavity 211. Therefore, the volume of the first barrier cavity 111 is larger than the volume of the second barrier cavity 211, that is, compared with the second concrete barrier 210, the first concrete barrier 110 can accommodate more concrete.

[0040] In some specific embodiments of the present invention, the first locking mechanism 100 also includes a first sealing assembly 120 and a first locking assembly 130. The first sealing assembly 120, the first concrete barrier 110 and the first locking assembly 130 are sequentially sleeved on the steel bar 10 in a direction away from the diaphragm formwork 30.

When the concrete breaks through the first sealing component 120 and overflows forward, the concrete enters the first barrier cavity 111 and flows outward through each first through hole 112. Under the action of the first barrier cavity 111, the concrete is blocked in the first concrete barrier 110, and it is difficult for the concrete to invade the first locking component 130, thereby avoiding the first locking component 130 from being solidified by the concrete, ensuring the free removal of the first locking mechanism 100.

Under the action of the second barrier cavity 211, the concrete is blocked in the second concrete barrier 210, and it is difficult for the concrete to invade the second locking component 230, thereby avoiding the second locking component 230 from being solidified by the concrete, ensuring the free removal of the second locking mechanism 200.

[0046] like Figure 1 As shown, the first pad 121, the first seal 122, the first concrete barrier 110, the first locking nut 131, and the first locking screw 132 are sequentially sleeved on the steel bar 10 extending from the diaphragm formwork 30 from the back to the front.

Tighten the first fastening bolt 133 and make it stuck in the groove surface of the steel bar 10, fix the first locking screw 132 to the steel bar 10, and finally rotate the first locking nut 131 to compress the diaphragm formwork 30 until the diaphragm formwork 30 is tightly fitted with the I-beam 20.

[0047] Similarly, the second pad 221, the second seal 222, the second concrete barrier 210, the second locking nut 231, and the second locking screw 232 are sequentially sleeved on the steel bar 10 extending from the diaphragm form 30 from the back to the front.

[0048] like Figure 5 As shown, the construction method of the I-beam diaphragm according to the second embodiment of the present invention includes:

[0049] Step 1: Tie the steel bars 10 and install the steel bars 10 on the I-beam;

[0050] Step 2: Assembling the diaphragm template 30;

[0051] Step 3: Use a template locking device to fix the diaphragm template 30 and the steel bar 10;

[0052] Step 4: pouring concrete in the diaphragm formwork 30;

[0053] Step 5: Remove the template locking device.

[0054] In some specific implementations of the present invention, in step 2, the corners of the diaphragm template 30 are repaired and leveled to form a smooth transition, and sealing rubber is attached to the periphery of the diaphragm template 30 to prevent leakage between two adjacent diaphragm templates 30.

[0055] In some specific implementations of the present invention, in step three, the first locking mechanism 100 and the second locking mechanism 200 are arranged on the diaphragm template 30 at intervals along the vertical direction.

[0056] In some specific implementations of the present invention, in step 4, concrete is poured in a layered slope manner.

[0057] The construction method of the I-beam diaphragm is described below with a specific embodiment:

[0058] Step 1: Clean the embedded sockets on the I-beam, install the main threaded steel with single-head teeth into the sockets and tighten them, and correct the horizontality of the steel bar 10, and tie the bent secondary threaded steel and the main threaded steel to fix them. When the steel bars 10 are tied and combined on site, all intersections of the steel bars 10 should be tied, and further, the two adjacent steel bars 10 should be spot welded to avoid displacement during concrete pouring. It should be noted that the steel bars 10 should be free of dust, rust, loose rust, paint, grease, oil or other foreign matter, and no harmful defects, and the production and installation of the steel bars 10 should be strictly carried out in accordance with the construction drawings and technical specifications to ensure the quality of welding.

[0059] Step 2: Add filling material and apply release agent to the corners of the original diaphragm template 30 to make the corners of the diaphragm template 30 have a smooth transition in an arc shape. It should be noted that the smooth transition corners can make the concrete flow more evenly during pouring, reduce the accumulation of concrete at the corners, avoid uneven stress distribution of concrete and possible crack formation, and reduce the adhesion between concrete and the template, making the template easier to disassemble after the concrete hardens, reducing the risk of template damage and improving construction efficiency. After repairing and leveling, apply sealing rubber to the outer ring of the edge of the diaphragm template 30 to prevent concrete from leaking from between two adjacent connected diaphragm templates 30. Place a jack at the bottom of the bottom plate of the diaphragm template 30 to adjust the bottom plate height, and finally fix the side template of the diaphragm template 30 to the bottom plate.

[0060] Step 3: Install the template locking device onto the corresponding steel bar 10. Specifically, first use the first locking mechanism 100 to lock the diaphragm template 30, and then use the second locking mechanism 200 to fix the diaphragm template 30. The first locking mechanism 100 and the second locking mechanism 200 are arranged at intervals in the vertical direction to prevent leakage when pouring cement. It should be noted that by arranging the first locking mechanism 100 and the second locking mechanism 200 at intervals, the diaphragm template 30 is alternately connected with the barrier chambers of different volumes to effectively control the flow rate and flow of cement. Specifically, the barrier chamber with a larger volume can accommodate more cement, so that it stays for a longer time and slows down the flow rate, while the barrier chamber with a smaller volume can allow cement to pass faster to maintain appropriate fluidity. In this way, the outflow speed of cement can be effectively controlled, making it more stable and controllable during the construction process. At the same time, by properly controlling the flow rate and flow of cement, cement waste can be reduced and the consistency of construction quality can be ensured.

[0061] Specifically, the first pad 121, the first seal 122, and the first concrete barrier 110 are sequentially sleeved on the steel bar 10, the first locking nut 131 and the first nail bolt 133 are installed on the first locking screw 132, and the first locking nut 131 is withdrawn to the front of the first locking screw 132 so that it abuts against the first nail bolt 133, and then the first locking screw 132 is sleeved on the steel bar 10 to press the first concrete barrier 110. The first nail bolt 133 is tightened and stuck in the groove surface of the steel bar 10, the first locking screw 132 is fixedly connected to the steel bar 10, and finally the first locking nut 131 is rotated to press the diaphragm formwork 30 until the diaphragm formwork 30 is tightly fitted with the I-beam 20.

[0062] Specifically, the second pad 221, the second seal 222, and the second concrete barrier 210 are sequentially sleeved on the steel bar 10, the second locking nut 231 and the second nail bolt 233 are installed on the second locking screw 232, and the second locking nut 231 is withdrawn to the front of the second locking screw 232 so that it abuts against the second nail bolt 233, and then the second locking screw 232 is sleeved on the steel bar 10 to press the second concrete barrier 210. The second nail bolt 233 is tightened and stuck in the groove surface of the steel bar 10, the second locking screw 232 is fixedly connected to the steel bar 10, and finally the second locking nut 231 is rotated to press the diaphragm formwork 30 until the diaphragm formwork 30 is tightly fitted with the I-beam 20.

[0063] In this specific embodiment, a beam member is provided at the bottom of the diaphragm, and a second locking mechanism 200 is used to be sleeved on the steel bars 10 extending outward from the beam member, and locked with the diaphragm formwork 30 at the beam member. It should be noted that the beam member usually has a relatively dense arrangement of steel bars 10, and it is necessary to ensure that the concrete can fully wrap and fill the steel bars 10 to provide sufficient strength and rigidity. Therefore, the use of a smaller volume of the second locking mechanism 200 can control the flow rate of cement, so that it can better penetrate and fill the gaps between the steel bars 10, while avoiding poor concrete flow, reducing the formation of cavities and bubbles, avoiding reducing the density and strength of the concrete, and ensuring the quality of the concrete around the steel bars 10.

[0064] Step 4: The concrete is mixed in a mixing plant, transported by a mixer truck, and poured into the formwork by a combing trough. Among them, the pouring adopts a layered slope pouring method, and the insert vibrator is used for vibrating. When using the insert vibrator, the moving distance does not exceed 1.5 times the vibrator's action radius, and the distance from the side form is maintained at 50 to 100 mm. It must be inserted into the lower layer of concrete by 50 to 100 mm. After each vibration is completed, the vibrating rod should be slowly raised while vibrating to avoid collision with the formwork, steel bars 10 and other embedded parts, and each vibrating part must be vibrated until the concrete at that part is dense. It should be noted that the sign of density is that the concrete stops sinking, no more bubbles emerge, and the surface is flat and slurry.
