Description

Technical Field

[0001] This utility model relates to the field of reinforced concrete cover plate technology, specifically to a pre-reserved hole structure for reinforced concrete cover plate construction. Background Technology

[0002] During the construction of reinforced concrete cover slabs, multiple pre-drilled holes are typically made on the surface of the slabs to facilitate hoisting and transfer. The construction of reinforced concrete cover slabs involves a large workload and a significant number of pre-drilled holes. Current technology usually involves workers using small shovels to remove concrete from both sides of the reinforcing bars during the initial setting of the concrete, creating recessed holes on either side of the bars. When hoisting the reinforced concrete cover slab, a hook is passed through these holes to lift the reinforcing bars, thus enabling the slab to be hoisted.

[0003] A search revealed a construction pre-reserved hole structure for reinforced concrete cover plates, comprising a forming groove with a reinforcing steel frame inside; a horizontally arranged abutment plate fixed inside the reinforcing steel frame, and a lifting ring fixed on the abutment plate; and a positioning component comprising two parallel positioning rods, with a positioning tube fixed between the two positioning rods, the length direction of the positioning rods being perpendicular to the axial direction of the positioning tube; the two positioning rods engaging with the groove wall of the forming groove, the bottom of the positioning tube abutting against the abutment plate, the lifting ring located inside the positioning tube, and the top of the positioning tube being higher than the upper surface of the forming groove.

[0004] While this technical solution has been implemented, at least the following drawbacks remain: Although the utility model allows for pre-drilling holes for the hoisting reinforcing bars, facilitating the subsequent hoisting of the reinforced concrete cover plate, it is inconvenient to clean the concrete mortar adhering to the surface of the positioning pipe after it separates from the poured concrete. This leads to the concrete mortar on the surface of the positioning pipe drying and affecting subsequent pre-drilling operations, necessitating improvement. Therefore, we propose a pre-drilling hole structure for reinforced concrete cover plate construction. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-reserved hole structure for reinforced concrete cover plate construction, which solves the problem mentioned in the background art that it is inconvenient to clean the concrete mortar adhering to the surface of the positioning pipe after the positioning pipe is separated from the poured concrete, resulting in the concrete mortar on the surface of the positioning pipe drying and affecting the subsequent operation of the pre-reserved hole.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pre-reserved hole structure for reinforced concrete cover plate construction, comprising a forming groove body (1), wherein a steel frame (11) is provided in the inner cavity of the forming groove body (1), and positioning tubes (12) are provided on both sides of the steel frame (11), a support frame (2) is provided on the outer side of the forming groove body (1), a fixing plate (3) is welded to the upper inner side of the support frame (2), guide wheels (21) are fixedly installed on both sides of the upper end of the fixing plate (3), scraping grooves (4) are opened on both sides of the fixing plate (3), and a straight rod (24) is welded to the upper inner cavity of the positioning tube (12), and a pull rope (22) is fixedly connected to the upper end of the straight rod (24).

[0007] By adopting the above technical solution, the positioning tube can be inserted into the gap of the steel frame, and then concrete can be poured into the main body of the forming groove. The stability of the positioning tube is ensured by the support frame and the pull rope, which further ensures the treatment of the reserved holes of the reinforced concrete cover plate. When the concrete initially sets, the pull rope can drive the straight rod to move upward, and the straight rod drives the positioning tube to move accordingly, which facilitates the separation of the positioning tube from the reinforced concrete cover plate. Then, the pull rope is pulled again, which allows the positioning tube to pass through the scraping groove on the fixed plate. The scraping groove can also clean the concrete mortar attached to the surface of the positioning tube, thereby avoiding the situation where the concrete mortar on the surface of the positioning tube dries and affects the subsequent operation of the reserved holes of other reinforced concrete cover plates.

[0008] Optionally, the size of the positioning tube is adapted to the size of the scraping groove, and the positioning tube is movably connected to the scraping groove.

[0009] By adopting the above technical solution and setting the scraping groove, the surface of the positioning tube can be scraped and cleaned.

[0010] Optionally, the other end of the pull rope passes around the guide wheel and extends through one side of the support frame.

[0011] By adopting the above technical solution and using the pull rope, the positioning tube can be pulled and lifted.

[0012] Optionally, a fixed ball is fixedly installed at the other end of the pull rope, and four fixed balls are provided.

[0013] By adopting the above technical solution and setting a fixed ball, the descent position of the pull rope can be limited, thereby controlling the reserved depth of the positioning tube.

[0014] Optionally, four positioning tubes are provided, and the positioning tubes are positioned within the gaps of the reinforcing steel frame.

[0015] By adopting the above technical solution and setting up positioning tubes, four holes can be reserved inside the steel frame.

[0016] Optionally, the positioning tube is disposed below the scraping groove, and the positioning tube corresponds one-to-one with the scraping groove.

[0017] By adopting the above technical solution and setting multiple scraping grooves, it is convenient to clean multiple positioning tubes.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: The technical solution of this application, through the setting of a forming groove body, a steel frame, a positioning tube, a support frame, a fixed ball, and a scraping groove, allows the positioning tube to be inserted into the gap of the steel frame. Concrete is then poured into the forming groove body, and the stability of the positioning tube is ensured by the support frame and the pull rope, further ensuring the treatment of the reserved holes in the reinforced concrete cover plate. When the concrete initially sets, the pull rope can drive the straight rod to move upward, and the straight rod drives the positioning tube to move accordingly, thus facilitating the separation of the positioning tube from the reinforced concrete cover plate. Then, the pull rope is pulled again, allowing the positioning tube to pass through the scraping groove on the fixed plate. This scraping groove cleans the concrete mortar adhering to the surface of the positioning tube, thereby preventing the concrete mortar on the surface of the positioning tube from drying and affecting the subsequent operation of the reserved holes in other reinforced concrete cover plates.

Fixed balls 23 are fixedly installed, and four fixed balls 23 are set. By setting the fixed balls 23, the descent position of the pull rope 22 can be limited, thereby controlling the reserved depth of the positioning tube 12. Four positioning tubes 12 are set and set in the gap of the steel frame 11. By setting the positioning tubes 12, four holes can be reserved in the steel frame 11. The positioning tubes 12 are set below the scraping grooves 4, and the positioning tubes 12 correspond one-to-one with the scraping grooves 4. By setting multiple scraping grooves 4, it is convenient to clean multiple positioning tubes 12.

[0022] The size of the positioning tube 12 is adapted to the size of the scraping groove 4, and the positioning tube 12 is movably connected to the scraping groove 4. Through the setting of the scraping groove 4, the surface of the positioning tube 12 can be scraped and cleaned.

[0023] The other end of the pull rope 22 passes around the guide wheel 21 and is inserted through one side of the support frame 2. The positioning tube 12 can be pulled and lifted by the pull rope 22.

[0024] When pouring the reinforced concrete cover plate, firstly, the reinforcing steel frame 11 is placed into the forming groove body 1, and then the support frame 2 is moved to the outside of the forming groove body 1 and positioned. Next, the fixing balls 23 are released, and the positioning tube 12 hangs into the gap of the reinforcing steel frame 11 by its own weight. Then, concrete is poured into the forming groove body 1. During this period, the positioning tube 12 is kept stable by the support frame 2 and the tensioned rope 22 to ensure the forming accuracy of the reserved hole. When the concrete is in the initial setting state, the four fixing balls 23 are pulled downwards, and the straight rod 24 and the positioning tube 12 are moved upwards synchronously by the rope 22, so that the positioning tube 12 is completely separated from the formed reinforced concrete cover plate. After that, the rope 22 is pulled upwards to force the positioning tube 12 to pass through the scraping groove 4 on the fixing plate 3. The scraping groove 4 is used to scrape the concrete mortar attached to the surface of the positioning tube 12 cleanly, effectively preventing the mortar from drying and affecting the subsequent reserved hole operation.
