Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, specifically to a positioning template device for concrete pouring in construction engineering. Background Technology

[0002] In construction projects, concrete pouring is a crucial step. To ensure that the structure formed after concrete pouring meets the design requirements, formwork is needed to determine the shape and position of the concrete. However, existing formwork devices for concrete pouring have some problems in practical applications.

[0003] On the one hand, the formwork needs to be installed on-site according to the size of the concrete to be poured. However, the existing formwork requires on-site scaffolding during installation, which is cumbersome and consumes a lot of manpower and time. Moreover, the formwork has poor versatility and is difficult to adapt to the needs of concrete pouring of different sizes and shapes.

[0004] On the other hand, traditional formwork has limited positioning accuracy. During the pouring process, the formwork is prone to displacement due to the impact of concrete and vibration, resulting in dimensional deviations in the poured concrete structure, affecting the appearance and quality of the building, and may even require rework, increasing construction costs and time. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a positioning template device for concrete pouring in construction projects, which is easy to assemble and disassemble and improves construction efficiency.

[0006] The specific technical solution is as follows: A positioning template device for concrete pouring in construction projects includes two horizontally and parallelly arranged installation beams, with a template assembly on one side and a fixing frame on the other side. The template assembly includes a limiting rod and a template. The limiting rod is fixedly installed between the two mounting beams, and the template is fixed on the side of the limiting rod away from the fixing frame. Positioning grooves are provided on the opposite sides of the two mounting beams. Positioning connecting blocks that are slidably disposed in the positioning grooves are provided at the upper and lower ends of the limiting rod. The limiting rod is also fixedly connected to the mounting beams through a fixing mechanism.

[0007] Preferably, the positioning groove and the connecting block are configured in a dovetail shape.

[0008] Preferably, the fixing mechanism includes a connecting plate and a fixing bolt. The connecting plate is disposed at the top and bottom of the limiting rod, and the fixing bolt passes through the connecting plate and is connected to the mounting beam.

[0009] Preferably, a fixing bracket connecting groove is provided on the side of the installation beam away from the template, and a fixing bracket connecting block that matches the connecting groove is provided on the fixing bracket; The mounting bracket connecting slot and the mounting bracket connecting block are configured in a dovetail shape.

[0010] Preferably, the two ends of the mounting beam are provided with a series connection structure, and two adjacent mounting beams are connected by the series connection structure.

[0011] Preferably, the serial connection structure includes a locking rod disposed at one end of the mounting beam, and the other end of the mounting beam has a locking groove for connecting the locking rod.

[0012] Preferably, the fixing frame is L-shaped, and a diagonal brace is fixedly installed on the side of the fixing frame away from the mounting beam.

[0013] A crossbeam connecting bolt is inserted through the front side of the fixing frame, and the rear side of the crossbeam connecting bolt contacts the front side of the mounting crossbeam.

[0014] The bottom of the mounting beam has two grooves, and expansion bolts are inserted into the grooves.

[0015] This utility model has the following beneficial effects: 1. The positioning formwork device for concrete pouring in this construction project utilizes positioning slots set on the installation beams to quickly connect formwork components, making installation and disassembly convenient, greatly shortening the formwork erection time and improving construction efficiency.

[0016] 2. Multiple installation beams on the same plane can be quickly spliced ​​by using slots and rods. During construction, the rod of the previous installation beam is inserted into the slot of the next installation beam. No additional welding or complex connectors are required to extend the overall length of the template. Compared with traditional fixed-length templates, this device does not require the purchase of multiple sets of templates for different length construction scenarios. It is especially suitable for the scenario in building engineering where "the same project contains multiple lengths of cast-in-place components".

[0017] The joints are reinforced with both fixed frames and diagonal braces to ensure overall flatness after splicing, avoiding concrete leakage caused by excessive gaps in traditional splicing templates, and improving the appearance quality of cast components.

[0018] 3. Adjustable thickness, suitable for various specifications of concrete components. In the template components, the number of limiting rods can be flexibly increased or decreased according to the thickness of the concrete pouring: when pouring thick components, the strength of the template support is improved by increasing the number of limiting rods to resist the lateral pressure of the concrete. Compared with traditional templates, which require different specifications of support components to be customized according to the thickness, this reduces the types of support components in stock and lowers warehousing and management costs.

[0029] like Figures 1-5 As shown, the positioning template device for concrete pouring in construction engineering provided in this embodiment includes two parallel installation beams 1. A fixing frame 2 is provided on the front side of the two installation beams 1, and a template assembly 3 is provided on the rear side of the two installation beams 1. The installation beams 1 are used to install the template assembly 3, and the fixing frame 2 is used to fix the two installation beams 1. At the same time, it can fix the installation beams 1 to the main body of the building or the ground, thereby realizing the overall installation. The template assembly 3 is used to form the mold cavity for pouring, thereby facilitating the subsequent pouring of concrete. At the same time, it can be spliced ​​and expanded according to the pouring needs to meet the construction needs of buildings of different lengths.

[0030] The template component 3 includes a limiting rod 301 located on the rear side between the two installation beams 1 and a template 302 located on the rear side of the limiting rod 301. The top and bottom of the template 302 are located on the top and bottom of the two installation beams 1. The limiting rod 301 is used to support the installation of the template 302. At the same time, the number can be selected according to the needs of pouring, so as to meet the pouring of concrete of different thicknesses and avoid the problem that the limiting rod 301 will deform due to the large amount of concrete poured during the actual pouring process, thus affecting the construction quality.

[0031] A positioning groove 303 is provided between the two mounting beams 1. A positioning connecting block 305 is slidably connected inside the positioning groove 303. One side of the positioning connecting block 305 is fixedly connected to the limiting rod 301. The positioning groove 303 and the positioning connecting block 305 are used to realize the connection between the limiting rod 301 and the mounting beam 1. At the same time, the limiting rod 301 can be added or removed according to the number used, and it is convenient to disassemble the whole after use.

[0032] In this embodiment, the positioning groove 303 and the positioning connecting block 305 are designed in a dovetail shape to prevent the limiting rod 301 from loosening.

[0033] Connecting plates 307 are fixedly installed on the top and bottom of the front side of the limiting rod 301. A fixing bolt 304 is inserted inside the connecting plate 307. One side of the fixing bolt 304 passes through the connecting plate 307 and contacts the mounting beam 1. The fixing bolt 304 and the connecting plate 307 are used to fix the limiting rod 301 to the mounting beam 1, thereby enabling the subsequent fixing of the template 302.

[0034] Two template fixing bolts 306 are inserted through the front side of the limiting rod 301. The rear side of the template fixing bolts 306 extends into the interior of the template 302 and is connected to the template 302 by threads. The template fixing bolts 306 are used to fix the template 302 relative to the limiting rod 301.

[0035] A slot 4 is provided on the right side of the mounting beam 1, and a clamping rod 5 is fixedly installed on the left side of the mounting beam 1. A diagonal brace 11 is fixedly installed on the front side of the fixing frame 2. The slot 4 and clamping rod 5 are provided to connect the two mounting beams 1 on the same plane. The diagonal brace 11 is provided to increase the stability and support of the mounting beam 1, thereby increasing the overall compressive strength.

[0036] A mounting frame connecting groove 8 is provided on the front side of the mounting beam 1. A mounting frame connecting block 9 is slidably connected inside the mounting frame connecting groove 8. One side of the mounting frame connecting block 9 is fixedly connected to the rear side of the mounting frame 2. A beam connecting bolt 10 is inserted through the front side of the mounting frame 2. The rear side of the beam connecting bolt 10 contacts the front side of the mounting beam 1. The mounting frame connecting groove 8 and the mounting frame connecting block 9 are provided to connect the mounting beam 1 and the mounting frame 2. The beam connecting bolt 10 is used to press the mounting beam 1. Under the limitation of the mounting frame connecting groove 8 and the mounting frame connecting block 9, the mounting frame 2 is fixed relative to the mounting beam 1. At the same time, after use, the mounting frame 2 can be removed relative to the mounting beam 1 by disassembling the beam connecting bolt 10.

[0037] In this embodiment, the fixing bracket connecting groove 8 and the fixing bracket connecting block 9 are also designed in a dovetail shape.

[0038] Two grooves 6 are provided at the bottom of the mounting beam 1. Expansion bolts 7 are inserted into the grooves 6. The grooves 6 are designed to accommodate the expansion bolts 7. The expansion bolts 7 are used to fix the building. The expansion bolts 7 can be selected according to specific needs.

[0039] How to use: 1. Site clearing and parameter confirmation The construction workers first cleaned the pouring site to ensure that the ground was flat, and confirmed the dimensional parameters of the concrete components according to the design drawings, including the length and thickness of the components, and planned the assembly scheme of the device accordingly.

[0040] Prepare the necessary parts and tools: Prepare the corresponding number of installation beams 1, fixing brackets 2, limit rods 301, templates 302 and various bolts according to the plan, and check the integrity of the parts to ensure smooth subsequent assembly.

[0041] 2. Pre-fitting of expansion bolts and grooves According to the fixing requirements of the pouring position, select the corresponding specification of expansion bolt 7, and pre-insert the expansion bolt 7 into the groove 6 at the bottom of the installation beam 1 to prepare for the subsequent fixing of the beam.

[0042] 3. Assembly of single-section installation beams Take two parallel mounting beams 1 and install a fixing bracket 2 on their front side: align the fixing bracket connecting block 9 on the rear side of the fixing bracket 2 with the fixing bracket connecting groove 8 on the front side of the mounting beam 1, and slide it along the connecting groove to the designated position to ensure that the mounting beam 1 and the fixing bracket 2 are initially positioned; then tighten the beam connecting bolt 10 on the front side of the fixing bracket 2. The bolts will press against the mounting beam 1. Under the limiting action of the fixing bracket connecting groove and the fixing bracket connecting block, the fixing bracket and the mounting beam will be tightly fixed by friction, forming a single-section "mounting beam + fixing bracket" frame.

[0043] Weld or bolt the diagonal brace 11 to the front side of the fixed frame 2. The bottom of the diagonal brace supports the ground or the main building structure, which transforms the horizontal force borne by the installed beam into a vertical support force, thereby improving the stability of the single-section frame.

[0044] 4. Splicing of multiple installation beams If the length of the concrete component exceeds the length of a single frame segment, multiple frame segments need to be spliced: Align the clamp 5 on the left side of the first installation beam 1 with the clamp 4 on the right side of the second installation beam and insert it horizontally to achieve quick positioning of the two installation beam segments; After splicing, check the parallelism of the two installation beam segments and install an additional fixing frame 2 at the splice to ensure stable spacing at the splice and avoid grout leakage due to loose splicing during pouring.

[0045] 5. Install the overall fixing of the crossbeam. Move the assembled installation beam frame to the pouring position and adjust the frame position to align it with the design pouring line; then tighten the expansion bolts 7 in the groove 6 at the bottom of the installation beam. The expansion bolts are drilled into the ground or the interior of the building structure to firmly fix the installation beam frame and prevent the frame from shifting during the pouring process.

[0046] 6. Installation and fixing of the limit rod The number and spacing of the limiting rods 301 are determined according to the thickness of the concrete component: the positioning connecting blocks 305 on both sides of the limiting rod 301 are aligned with the positioning grooves 303 between the two installation beams 1, and slid along the connecting grooves to the designated position to achieve the initial positioning of the limiting rods and the installation beams. Then, the fixing connecting bolts 304 are tightened through the connecting plates 307 at the top and bottom of the front side of the limiting rod. The bolts penetrate the connecting plates and press against the installation beams 1 to fix the limiting rods between the installation beams, forming a support structure perpendicular to the installation beams.

[0047] After the limit rods are installed, check their spacing for uniformity to ensure that the subsequent template installation is flat and to avoid the template being unbalanced due to uneven spacing of the limit rods.

[0048] 7. Template installation and fixing The template 302 is attached to the back of the limiting rod 301. The position of the template is adjusted so that its top and bottom extend beyond the installation beam 1. Then, the template fixing bolt 306 is inserted through the front of the limiting rod 301. The back of the bolt extends into the interior of the template 302 and is threadedly connected to the template. After tightening the bolt, the template and the limiting rod are tightly fixed. The template, the installation beam, and the limiting rod together form the mold cavity for concrete pouring.

[0049] If the height of the component exceeds the height of a single template, template splicing is required: align the joints of the upper and lower templates, add an additional limiting rod 301 at the joint, and fix the template joint with template fixing bolts to ensure that there are no gaps at the joint and avoid grout leakage during pouring.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
