Abstract
Description
Technical Field
[0001] The present invention relates to the field of cast-in-place beam construction, and particularly to a device for filling the tie rod holes of a cast-in-place beam and a method for using the same. Background Art
[0002] The web of a cast-in-place box girder refers to the vertical part connecting the upper and lower flanges. There are generally two methods for measuring and filling the tie rod holes of the web of a cast-in-place beam. The first method is to set up a working scaffold on the outside of the beam, and arrange construction workers in both the working scaffold and the beam body. To prevent the mortar filled in the tie rod holes from dripping outside, the construction workers on the working scaffold fill the mortar from the outside to the inside. After the mortar in the hole is basically in place, the construction workers inside the beam body seal the holes inside the beam body, and the construction workers on the working scaffold continuously squeeze the mortar until it is all compacted and then leveled and finished. The second method is to set up an external working hanging basket by using the embedded parts on the top surface of the beam body. The steps of setting up the hanging basket as a working scaffold are the same as those of the first method. When the height of the beam body is relatively low, a boom lift can also be used for operation.
[0003] In the existing construction of filling the tie rod holes of a cast-in-place beam, construction workers are arranged to operate on both sides of the tie rod holes of the beam body. The construction workers outside the beam body working at heights have potential safety hazards, and after construction, whether it is setting up a working scaffold or a hanging basket, it needs to be demolished, which is time-consuming and laborious. Summary of the Invention
[0004] The purpose of the present invention is to provide a device for filling the tie rod holes of a cast-in-place beam and a method for using the same, so as to solve the problems that during the process of filling the tie rod holes of a cast-in-place beam, there are potential safety hazards for the construction workers outside the beam body, and it is time-consuming, laborious and inefficient to demolish the working scaffold and the hanging basket.
[0005] To solve the above technical problems, the technical solutions adopted by the present invention are as follows: A device for filling the tie rod holes of a cast-in-place beam, comprising a plugging block, a measuring pressure rod, a degradable film, a threaded gasket and a positioning bolt; The measuring pressure rod is provided with horizontal scales; The plugging block is arranged at the end of the measuring pressure rod; The degradable film is sleeved on the outer wall of the measuring pressure rod; The threaded gasket and the positioning bolt cooperate to press the degradable film tightly, so as to tightly adhere and sleeve the degradable film on the measuring pressure rod.
[0006] As a further technical solution of the above scheme, the measuring pressure rod comprises a first section and a second section; the left end of the first section is connected to the plugging block, and the right end is provided with an internal connecting thread; the left end of the second section is provided with an external connecting thread matching the internal connecting thread.
[0007] The present invention also provides a method for using the device for filling the tie rod holes of a cast-in-place beam as claimed in claim 1, comprising the following steps: Step S1: Measure the tie rod holes of the cast-in-place beam body. According to the hole depth, fit the degradable film sleeve on the outer wall of the measuring strut and tighten the degradable film. Step S2: Tighten and fix the two ends of the degradable film to the upper and lower ends of the threaded gasket respectively, and use the positioning bolts to tighten and fix the two ends of the degradable film. Step S3: The construction worker inserts the measuring strut into the tie rod hole, presses the positioning bolt and the threaded gasket by hand, and rotates the measuring strut out of the tie rod hole outward, leaving the degradable film in the tie rod hole. Step S4: Stuff mortar into the tie rod hole. Insert the measuring strut into the tie rod hole again, and the plug squeezes the mortar at the front end. After every 50 mm - 100 mm of mortar stuffing and squeezing amount is completed, rotate the measuring strut out of the tie rod hole outward; repeat the above operation until the mortar fills the tie rod hole. Step S5: Smooth and close the ends of the tie rod holes on the inner side of the web of the cast-in-place beam body to complete the stuffing of the tie rod holes.
[0008] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. In the present invention, the degradable film is sleeved on the measuring strut, fixed with a threaded gasket and positioning bolts. After setting the degradable film by inserting the measuring strut into the tie rod hole, the measuring strut is rotated out of the tie rod hole, and then mortar is stuffed into the tie rod hole. The plug is used to squeeze the mortar in the hole until the mortar fills the entire tie rod hole, completing the entire stuffing operation of the tie rod hole. The construction worker can complete the entire operation inside the beam body, avoiding the construction worker from working at height using a scaffold or a hanging basket, and eliminating potential safety hazards.
[0009] 2. The length of the measuring strut can be adjusted according to the hole depth of the tie rod hole to adapt to different tie rod holes. The measuring strut is convenient to use, and the construction worker can directly hold it by hand to complete the operation, avoiding the installation and removal of construction platforms such as scaffolds or hanging baskets, and improving the construction efficiency.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems to be solved, the technical features constituting the technical solutions, and the technical effects brought.
[0020] As Figures 1-8 shown, a device for filling the tension bar hole of a cast-in-place beam body includes a sealing block 1, a measuring compression bar 2, a degradable film 3, a threaded gasket 4 and a positioning bolt 5; The measuring compression bar 2 is provided with horizontal scales; The sealing block 1 is arranged at the end of the measuring compression bar 2; The degradable film 3 is sleeved on the outer wall of the measuring compression bar 2; The threaded gasket 4 and the positioning bolt 5 cooperate to press the degradable film 3 tightly, and are used to tightly attach and sleeve the degradable film on the measuring compression bar.
[0021] When filling the tie rod holes of the cast-in-place beam body, only construction personnel need to be arranged inside the beam body. First, put the measuring pressure rod 2 into the tie rod hole 6. When the left end of the measuring pressure rod 2 extends to the leftmost end of the tie rod hole 6, the plugging block 1 extends out of the tie rod hole 6, and the lower end of the plugging block 1 abuts against the lower wall outside the tie rod hole 6. The leftmost end of the measuring pressure rod 2 is flush with the leftmost end of the tie rod hole 6, which is convenient for observing the reading of the measuring pressure rod 2. Determine the depth of the tie rod hole 6 according to the reading of the measuring pressure rod 2. According to the actual hole depth, put the fully biodegradable film with plum blossom holes and a thickness of 0.2 mm on the outer wall of the measuring pressure rod 2, and tighten the biodegradable film 3. Fix the two ends of the biodegradable film 3 on the threaded washers 4 respectively and then fix them with the positioning bolts 5. Since the whole biodegradable film 3 is sleeved on the measuring pressure rod 2, the position of the biodegradable film 3 can be determined according to the reading of the measuring pressure rod 2 and fixed at a position greater than the depth of the tie rod hole 6; Insert the biodegradable film 3 together with the measuring pressure rod 2 into the interior of the tie rod hole 6. The construction personnel press the positioning bolts 5 and the threaded washers 4 tightly and screw the measuring pressure rod 2 out of the tie rod hole 6. Fill the tie rod hole 6 with mortar, and use the plugging block 1 to compact the mortar. Repeat the operation to make the mortar fill the whole tie rod hole 6. After filling, the construction personnel smooth and close the right end of the tie rod hole 6 inside the beam body. With the action of the fresh water biological environment, the fully biodegradable film is gradually decomposed into simple compounds such as carbon dioxide and water.
[0022] As Figure 5 shown, as a preferred embodiment, the measuring pressure rod 2 includes a first section 21 and a second section 22; the left end of the first section 21 is connected to the plugging block 1, and the right end is provided with a connecting internal thread; the left end of the second section 22 is provided with a connecting external thread matching the connecting internal thread. In this embodiment, the measuring pressure rod 2 is set as the first section 21 and the second section 22, and is set according to the depth of the tie rod hole 6 during use. When the depth of the tie rod hole 6 is too deep, the second section 22 is used to lengthen the overall measuring pressure rod 2 to adapt to different tie rod holes 6.
[0023] The present invention also provides a use method of a filling device for tie rod holes of a cast-in-place beam body, including the following steps: Step S1, measure the tie rod holes of the cast-in-place beam body, and put the biodegradable film 3 on the outer wall of the measuring pressure rod 2 according to the hole depth and tighten the biodegradable film; Step S2, respectively tighten and fix the two ends of the biodegradable film 3 on the upper and lower ends of the threaded washer 4, and use the positioning bolt 5 to tighten and fix the two ends of the biodegradable film 3; Step S3, the construction personnel insert the measuring pressure rod 2 into the tie rod hole 6, press the positioning bolt 5 and the threaded washer 4 by hand, and screw the measuring pressure rod 2 out of the tie rod hole 6 outward, and the biodegradable film 3 remains in the tie rod hole 6; Step S4, fill the mortar into the tie rod hole 6, insert the measuring pressure rod 2 into the tie rod hole 6 again, squeeze the mortar at the front end of the blocking block 1, and after completing 50mm-100mm of mortar filling and squeezing, rotate the measuring pressure rod 2 out of the tie rod hole 6; repeat the above operation until the mortar fills the tie rod hole 6; Step S5, smoothing and closing the ends of the tie rod holes 6 on the inner side of the web of the cast-in-place beam body to complete the filling of the tie rod holes.
[0024] When using this device, first measure the depth of the tie rod hole of the cast-in-place beam, determine the length of the degradation film according to the depth of the tie rod hole, put the fully biodegradable degradation film on the outer wall of the measuring pressure rod, then pass the measuring pressure rod through the threaded gasket, tighten the two ends of the degradation film on the upper and lower ends of the threaded gasket respectively, and fix it with positioning bolts to complete the setting of the measuring pressure rod. The construction personnel carry out construction from the inside of the beam body, hold the measuring pressure rod and insert it into the tie rod hole, press the positioning bolts and threaded gaskets by hand, and unscrew the measuring pressure rod from the tie rod hole. At this time, the degradation film remains in the tie rod hole, and the left end of the degradation film is flush with the left end of the cylinder hole. The degradation film acts as a template similar to that in the pouring process to prevent mortar from dripping from the left end of the tie rod hole. After the degradable film is set, the construction personnel will fill the mortar into the tie rod hole. After filling, the measuring pressure rod will be inserted into the tie rod hole. The blocking block at the front end of the measuring pressure rod will contact the mortar at the front end of the extrusion. The biodegradable film is set to a plum blossom hole to facilitate mortar filling. When the extrusion is 50-100mm, the measuring pressure rod is taken out and refilled with mortar. The operation is repeated until the mortar is filled. After filling, the construction personnel will smooth and close the right end face of the tie rod hole on the inner side of the beam body. The fully biodegradable film decomposes into water and carbon dioxide over time, which does not affect the environment or the mortar forming. In this embodiment, it is possible to choose to fill the hole after taking out all the measuring pressure rods from the tie rod hole, or it is possible to make the tie rod hole hollow, fill from the rear end of the tie rod hole and realize filling from the front end outlet, so that the measuring pressure rod can be avoided from being taken out multiple times. The fluidity of the mortar is weak. In actual use, it may be necessary to select a push rod with a smaller radius to insert into the measuring pressure rod to push. The construction method adopted can be selected according to the specific construction environment.
