Technical Field

[0001] This utility model belongs to the field of building formwork technology, and more specifically, it relates to a formwork for pouring concrete during building construction. Background Technology

[0002] Construction formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components according to specified positions and geometric dimensions, maintain their correct position, and bear the self-weight of the formwork and external loads acting on it. The purpose of formwork engineering is to ensure the quality and safety of concrete engineering, accelerate the construction progress, and reduce project costs.

[0003] Application number CN201820279036.1 discloses a formwork for pouring concrete in building construction, including fixed supports and a pouring body. Fixed supports are provided on both the left and right sides of the pouring body, and the fixed supports are fixedly connected to the pouring body by bolts. Crossbeams are provided on the upper and lower sides of the front of the pouring body, and the crossbeams are fixedly connected to the pouring body by bolts. Two crossbeams are provided on each of the left and right sides of the pouring body, and the crossbeams are also fixedly connected to the pouring body by bolts. This formwork for pouring concrete in building construction features an anti-loosening nut at the bottom of the fixing device. The inner diameter of the anti-loosening nut is the same as the diameter of the bottom of the fixing device, and the upper surface of the anti-loosening nut has threads on the contact surface with the pouring body. The fixing device is locked by friction through the anti-loosening nut at the bottom of the fixing device, thus solving the problem of safety hazards caused by spontaneous loosening due to vibration or other reasons during previous building construction. This formwork has broad application prospects.

[0004] Based on the above patent search and understanding of the application of existing building construction pouring formwork:

[0005] 1. In the process of building construction and pouring concrete, traditional pouring molds are difficult to flexibly form into specific cylindrical shapes, making it difficult to meet the manufacturing requirements of cylindrical concrete components;

[0006] 2. During the concrete pouring process, air bubbles are easily generated inside, forming hollow gaps, which leads to a decrease in the quality of concrete components and affects their structural strength and stability. Existing vibration methods are inefficient and have unsatisfactory results. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a construction pouring template to solve the problem that existing pouring molds are difficult to flexibly assemble into specific cylindrical shapes during the construction pouring process, making it difficult to meet the requirements of manufacturing cylindrical concrete components and the tendency for air bubbles to form hollow gaps during concrete pouring, leading to a decrease in the quality of concrete components and affecting their structural strength and stability.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A formwork for pouring concrete in building construction includes a support frame; an external frame is fixedly installed at the top of the support frame, and the upper rear end of the external frame is fixedly connected to the lower front end of a control frame. The control frame is located directly above the support frame, and a sliding rod is slidably connected to the bottom of the control frame. The bottom of the sliding rod is fixedly connected to the top of the formwork frame, and the sliding rod slides at the middle of the top of the support frame. The formwork frame is located at the upper middle of the interior of the support frame. Three sliding grooves are provided at the bottom of the formwork frame, and the three sliding grooves are distributed in a Y-shape. A sliding block is slidably connected in each of the three sliding grooves. An arc-shaped template is fixedly connected to the bottom of each sliding block. The three arc-shaped templates are distributed in a ring, and the bottom of the arc-shaped templates is designed as a semi-fan shape. When the three arc-shaped templates are fitted together, they form a cylindrical shape.

[0010] According to one embodiment of the present invention, the rear middle position of the control frame is fixedly connected to the front end position of the motor A, the front end position of the rotating shaft of the motor A is fixedly connected to the rear end position of the U-shaped part, and the U-shaped part is rotatably connected to the inner middle position of the control frame.

[0011] According to one embodiment of the present invention, the middle protrusion of the U-shaped member is rotatably connected to the upper position of the transmission arm, the lower position of the transmission arm is rotatably connected to the top position of the sliding rod, and the transmission arm is located inside the control frame.

[0012] According to one embodiment of the present invention, a motor B is fixedly connected to the middle position of the front end of the mold frame, and a bevel gear is fixedly installed on the rear shaft of the motor B. The bevel gear is located at the front end of the mold frame.

[0013] According to one embodiment of the present invention, a bevel gear ring is rotatably connected to the middle position inside the mold frame. The top front end of the bevel gear ring meshes with the bottom position of the bevel gear for transmission. A spiral groove is provided at the bottom position of the bevel gear ring.

[0014] According to one embodiment of the present invention, each of the three sliding blocks has an arc-shaped groove at its top position, and the arc-shaped grooves of the three sliding blocks engage with the spiral groove of the bevel gear ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting three Y-shaped sliding grooves at the bottom of the mold frame, sliding blocks that slide in the grooves, and arc-shaped templates fixed at the bottom of the sliding blocks, the motor B is started to drive the bevel gear to rotate, which in turn causes the bevel gear ring to rotate, so that the three sliding blocks slide in the grooves, driving the three arc-shaped templates to move and fit together to form a cylindrical shape, thus meeting the needs of cylindrical concrete pouring in building construction.

[0017] 2. When motor A drives the U-shaped part to rotate, the sliding rod slides back and forth through the cooperation between the U-shaped part and the transmission arm, causing the mold frame to move back and forth in height. This vibrates the concrete inside the three arc-shaped molds, effectively expelling air bubbles from the concrete, preventing the formation of hollow gaps, improving the quality of the concrete components, and enhancing their structural strength and stability.

[0018] 3. During demolding, motor B drives the bevel gear to rotate in the opposite direction, and the three sliding blocks will slide away from each other in the groove of the mold frame, so that the three arc-shaped templates are separated, which facilitates the rapid demolding of the cylindrical concrete parts formed inside the three sliding blocks. This simplifies the demolding operation, saves time and manpower, reduces damage to the formed concrete components, and helps to improve the construction progress and reduce construction costs.

[0029] Example:

[0030] As attached Figure 1 To be continued Figure 5 As shown:

[0031] This utility model provides a formwork for pouring concrete in building construction, including a support frame 1. An external frame 101 is fixedly installed at the top of the support frame 1. The upper rear end of the external frame 101 is fixedly connected to the lower front end of a control frame 102. The control frame 102 is located directly above the support frame 1. A sliding rod 106 is slidably connected to the bottom of the control frame 102. The bottom of the sliding rod 106 is fixedly connected to the top of a mold frame 2, and the sliding rod 106 slides at the middle of the top of the support frame 1. The mold frame 2 is located at the upper middle of the interior of the support frame 1. Three sliding grooves are provided at the bottom of the mold frame 2, and the three sliding grooves of the mold frame 2 are distributed in a Y-shape. A sliding block 204 is slidably connected to each of the three sliding grooves of the mold frame 2. An arc-shaped template 205 is fixedly connected to the bottom of each sliding block 204. The three arc-shaped templates 205 are arranged in a ring. The bottom of the arc-shaped templates 205 is designed as a semi-fan shape. When the three arc-shaped templates 205 are fitted together, they form a cylindrical shape. The middle of the rear end of the control frame 102 is fixedly connected to the front end of the motor A103. The front end of the shaft of the motor A103 is fixedly connected to the rear end of the U-shaped part 104. The U-shaped part 104 is rotatably connected to the middle of the inside of the control frame 102. The middle protrusion of the U-shaped part 104 is rotatably connected to the upper part of the transmission arm 105. The lower part of the transmission arm 105 is rotatably connected to the top of the sliding rod 106. The transmission arm 105 is located inside the control frame 102.

[0032] Among them, a motor B201 is fixedly connected to the middle position of the front end of the mold frame 2. A bevel gear 202 is fixedly installed on the rear shaft of the motor B201. The bevel gear 202 is located at the front end of the mold frame 2. A bevel gear ring 203 is rotatably connected to the middle position of the mold frame 2. The top front end position of the bevel gear ring 203 meshes with the bottom position of the bevel gear 202 for transmission. A spiral groove is provided at the bottom position of the bevel gear ring 203. An arc groove is provided at the top position of each of the three sliding blocks 204. The arc grooves of the three sliding blocks 204 mesh with the spiral grooves of the bevel gear ring 203.

[0033] When using:

[0034] Place the support frame 1 at the predetermined position in the building construction to ensure the stability of the support frame 1. Start the motor B201 to drive the bevel gear 202 to rotate. Since the bevel gear 202 is located at the front end of the mold frame 2 and meshes with the front end of the top bevel gear ring 203, the rotation of the bevel gear 202 will drive the bevel gear ring 203 to rotate in the middle position inside the mold frame 2.

[0035] The bottom of the conical ring 203 is provided with a spiral groove, and the arc-shaped grooves on the top of the three sliding blocks 204 mesh with the spiral groove of the conical ring 203. The rotation of the conical ring 203 will cause the three sliding blocks 204 to slide in the groove at the bottom of the mold frame 2, thereby driving the three arc-shaped templates 205 to move until each two adjacent arc-shaped templates 205 fit together to form a cylindrical shape. Concrete material is poured into the cylinder formed by the three arc-shaped templates 205 and waits for it to be formed.

[0036] To prevent air bubbles from creating hollow gaps in the concrete inside the three curved templates 205, motor A103 is started to rotate the U-shaped component 104. Through the cooperation of the U-shaped component 104 and the transmission arm 105, the sliding rod 106 slides back and forth inside the control frame 102, thereby causing the entire mold frame 2 to move back and forth in height. The force of the mold frame 2 moving up and down will vibrate the concrete inside the three curved templates 205, expelling internal air bubbles.

[0037] When demolding, motor B201 drives bevel gear 202 to rotate in the opposite direction, and the three sliding blocks 204 will slide away from each other in the groove of mold frame 2, which facilitates the rapid demolding of the cylindrical concrete parts formed inside the three sliding blocks 204.
