Description

Technical Field

[0001] This invention belongs to the technical field of concrete beam molds, and particularly relates to a quick-release mold for concrete beams and its usage method. Background Technology

[0002] A concrete beam is a beam made of reinforced concrete. Concrete beams come in various forms and are the most basic load-bearing components in building construction, bridge construction, and other engineering structures, with a wide range of applications. In order to improve construction speed and efficiency, precast concrete beams are often used during construction. During precasting, concrete beams require the use of molds for solidification and shaping.

[0003] Research revealed that existing concrete beam manufacturing molds are complex, time-consuming, and inefficient to disassemble after beam forming, lacking quick-release mechanisms, which impacts the production efficiency of concrete beams. Therefore, there is an urgent need to improve existing concrete beam molds to develop a quick-release mold for concrete beams. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a quick-release mold for concrete beams and its method of use to solve the problems mentioned in the background art or to achieve better technical effects.

[0005] To solve the above-mentioned technical problems, the inventors derived the technical solution of this invention through practice and summarization. This invention discloses a quick-release mold for concrete beams, including a base plate, a support plate, a first mold assembly, and a second mold assembly. The support plate is fixedly installed at the top center of the base plate, and a bottom template is fixedly installed at the top of the support plate. First supports are fixedly installed on the left and right outer walls of the support plate, and a first mold assembly is installed on each set of first supports. Second supports are fixedly installed on the front and rear outer walls of the support plate, and a second mold assembly is installed on each set of second supports.

[0006] Preferably, a fixing frame is fixedly installed on the upper left side of the base plate, and a mounting shaft is connected to the top bearing of the fixing frame. A worm gear is fixedly sleeved on the outer side of the mounting shaft.

[0007] Preferably, a servo stepper motor is also fixedly installed on the upper left side of the base plate. The output end of the servo stepper motor is fixedly connected to a worm gear, which is located on the side end of the worm wheel and meshes with the worm wheel.

[0008] Preferably, the first mold assembly includes a first horizontal shaft, a first bevel tooth, a first side template, an L-shaped rod, and a positioning bolt, wherein the first horizontal shaft passes through the first bracket and is connected to the bearing of the first bracket.

[0009] Preferably, both ends of the first horizontal shaft are fixedly equipped with first bevel teeth, and the outer side of the first horizontal shaft is fixedly connected to a first side template. The top and rear outer walls of the first side template are both connected to L-shaped rods by bearings.

[0010] Preferably, the vertical section of the L-shaped rod is threaded with a positioning bolt.

[0011] Preferably, the second mold assembly includes a second horizontal shaft, a second bevel gear, and a second side template. The second horizontal shaft passes through the second bracket and is connected to the second bracket bearing. The second bevel gear is fixedly installed at both ends of the second horizontal shaft, and the second side template is fixedly connected to the outer side of the second horizontal shaft.

[0012] Preferably, the top left and right ends of the second side template are provided with through grooves, and positioning holes are provided directly below the through grooves, and the second bevel teeth mesh with the corresponding first bevel teeth.

[0013] Preferably, the L-shaped rod is engaged with the second side template through a through groove, and the positioning hole is adapted to the positioning bolt.

[0014] As a preferred embodiment, the method of using any of the above-mentioned quick-release molds for concrete beams includes the following steps:

[0015] S1: First, place the steel reinforcement cage between the bottom formwork, the two first side formworks and the two second side formworks, and then pour in an appropriate amount of concrete;

[0016] S2: Cover the existing upper formwork over the concrete. After the concrete beam is formed, remove the upper formwork and start the servo stepper motor on the upper left of the base plate to control the worm gear to rotate. Use the worm wheel to drive the installation shaft, the second bevel gear, the second horizontal shaft, and the second side formwork to rotate and open. Use the first bevel gear that meshes with the second bevel gear to control the first horizontal shaft and the first side formwork to move in conjunction with the second side formwork. This makes it easy to control the two first side formworks and the two second side formworks to rotate synchronously to a horizontal state, so that the formed concrete beam can be demolded quickly and disassembled quickly.

[0017] S3: After demolding, control the first mold assembly and the second mold assembly to reset. One end of the L-shaped rod can pass through the internal through groove of the second side template. Then, the L-shaped rod can be manually rotated so that its vertical section faces downward. Then, tighten the positioning bolt so that one end is inserted into the positioning hole, so that the L-shaped rod and the second side template are stably engaged, enhancing the stability of the connection between the first side template and the second side template.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) The present invention controls the rotation of the worm gear by starting the servo stepper motor. The worm gear meshing with the worm gear drives the installation shaft, the second bevel tooth, the second horizontal shaft and the second side template to rotate and open. The first bevel tooth meshing with the second bevel tooth can control the linkage between the first horizontal shaft and the first side template and the second side template, which makes it easy to control the two first side templates and the two second side templates to rotate synchronously to the horizontal state. This facilitates the rapid demolding of the formed concrete beam, quick disassembly and easy use, and can improve the production efficiency of concrete beams.

[0020] (2) When the first side template and the second side template are both in a vertical state for concrete pouring and prefabrication, one end of the L-shaped rod can pass through the internal through groove of the second side template. Then the L-shaped rod can be rotated so that its vertical section is downward and the positioning bolt is tightened so that one end is inserted into the positioning hole. This facilitates the stability of the connection between the first side template and the second side template and facilitates the stable use of the concrete beam mold. Attached Figure Description

[0043] Preferably, the two sets of first mold components 5 and the two sets of second mold components 7 are linked together.

[0044] In this embodiment, the first mold assembly 5 and the second mold assembly 7 are linked together, which facilitates the operation and adjustment of the mold.

[0045] Preferably, the first mold assembly 5 includes a first horizontal shaft 51, a first bevel gear 52, a first side template 53, an L-shaped rod 54, and a positioning bolt 55. The first horizontal shaft 51 passes through the first bracket 4 and is connected to its bearing. The first bevel gear 52 is fixedly installed at both ends of the first horizontal shaft 51. The first side template 53 is fixedly connected to the outer side of the first horizontal shaft 51. The L-shaped rod 54 is connected to the bearing on the outer walls of the front and rear sides of the top of the first side template 53.

[0046] Preferably, the vertical section of the L-shaped rod 54 is threaded with a positioning bolt 55.

[0047] In this embodiment, the L-shaped rod 54 and the positioning bolts 55 installed on its vertical section are used to improve the connection strength and stability between the first mold assembly 5 and the second mold assembly 7, which facilitates the stable use of the mold.

[0048] Preferably, the second mold assembly 7 includes a second horizontal shaft 71, a second bevel tooth 72, and a second side template 73. The second horizontal shaft 71 passes through the second bracket 6 and is connected to its bearing.

[0055] Example 2

[0056] A method for using a quick-release formwork for concrete beams, the steps of which are as follows:

[0057] When using it, first place the steel reinforcement cage between the bottom formwork 3, the two first side formworks 53 and the two second side formworks 73, and then pour in an appropriate amount of concrete;

[0058] The existing upper formwork can then be placed over the concrete. After the concrete beam is formed, the upper formwork is removed, and the servo stepper motor 11 on the upper left of the base plate 1 is started to control the worm gear 12 to rotate. The worm wheel 10 drives the mounting shaft 9, the second bevel gear 72, the second horizontal shaft 71, and the second side formwork 73 to rotate and open. The first bevel gear 52, which meshes with the second bevel gear 72, can control the linkage between the first horizontal shaft 51 and the first side formwork 53 and the second side formwork 73, making it easy to control the two first side formwork 53 and the two second side formwork 73 to rotate synchronously to a horizontal state. Figure 3 The state shown in the figure facilitates the rapid demolding of the formed concrete beam, making it quick to disassemble and easy to use, which can improve the production efficiency of concrete beams.

[0059] When the first mold assembly 5 and the second mold assembly 7 are reset after demolding, one end of the L-shaped rod 54 can pass through the internal through groove 74 of the second side template 73. Then, the L-shaped rod 54 can be manually rotated so that its vertical section faces downward, and the positioning bolt 55 can be tightened so that one end is inserted into the positioning hole 75. This facilitates the stable engagement between the L-shaped rod 54 and the second side template 73, thereby effectively enhancing the stability of the connection between the first side template 53 and the second side template 73 and facilitating the stable use of the concrete beam mold.

[0060] The device of this invention is powered by an external power supply. The servo stepper motor 11 can be electrically connected to an external PLC controller terminal via a connecting cable, which facilitates the control of the rotation angle of the first mold assembly 5 and the second mold assembly 7. The specific control methods are already very mature in the prior art and are not the key innovation direction of this case, so they will not be described in detail.
