Description

Technical Field

[0001] The utility model relates to the field of building prefabricated component production equipment, and particularly relates to a wall formwork support frame. Background Art

[0002] A precast wall panel is a concrete slab-shaped component processed in a precast factory or construction site for building assembly. Using precast concrete wall panels to build an assembled building can improve the degree of factoryization and mechanization of construction, save on-site labor, and shorten the building construction period.

[0003] Hebei Lijian Liju Integrated Housing Co., Ltd. applied for a utility model patent for a modular precast wall panel (publication number CN207453256U) in 2017. This wall panel can be spliced to form the entire wall, has relatively high strength, and the connection between wall panels adopts a detachable connection form, using double-headed bolts for connection, and can be freely assembled and disassembled.

[0004] Subsequently, Hebei Lugang Housing Manufacturing Co., Ltd. applied for a utility model patent for a wall formwork support frame (publication number CN213837762U) in 2020, which can be used to produce the above-mentioned precast wall panel. This patent uses an elastic clamping device to prevent the loss of the connecting shaft.

[0005] In the actual use process, it is found that after precasting, since the connecting shaft is also wrapped in the concrete together, a relatively large external force is required to complete the disassembly of the connecting shaft. It is difficult to complete by manual labor and the efficiency is low. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a wall formwork support frame that can automatically disassemble the connecting shaft with higher efficiency.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A wall formwork support frame includes a chassis, side forms arranged around the chassis, a mold box arranged inside the side forms, and a connecting shaft arranged on the mold box. A driving device for moving the connecting shaft along its axial direction is arranged between the side form and the connecting shaft. The mold box includes corner mold boxes arranged at the four corners of the chassis and side mold boxes arranged at the middle and near-side positions of the chassis. Connecting shafts are arranged on one side of the mold box close to the side form.

[0009] Further, the driving device includes a mounting plate arranged on the side surface of the side form and a telescopic rod with one end arranged on the mounting plate through a rotating shaft. The other end of the telescopic rod is connected to the connecting shaft through a rotating shaft.

[0010] Further, the number of the telescopic rods is two, which are symmetrically arranged on the left and right sides of the connecting shaft respectively.

[0011] Furthermore, a limiting block is provided on the mounting plate and at a position on the side of the telescopic rod close to the side form. The side of the limiting block facing the telescopic rod is an inclined slope, and it cooperates with the telescopic rod when the connecting shaft is in the innermost position.

[0012] Furthermore, the telescopic rod is a cylinder or an electric push rod.

[0013] Furthermore, a stabilizing block is provided on the side form, and a through hole is provided on the stabilizing block. One end of the connecting shaft passes through the through hole and then cooperates with the connecting hole on the mold box.

[0014] Furthermore, the connecting shaft includes a cylindrical section and a conical section provided at one end of the cylindrical section. One end of the telescopic rod is connected to the cylindrical section, and the conical section passes through the through hole on the stabilizing block and then cooperates with the mold box.

[0015] Furthermore, two connecting shafts are provided on the corner mold box and are respectively located on the side of the corner mold box close to the side form. One connecting shaft is provided on the side mold box and is located on its side close to the side form.

[0016] The positive effects of the present utility model are as follows:

[0017] The present utility model drives the connecting shaft to perform axial movement by using a driving device. When it is necessary to disassemble after prefabrication is completed, it is automatically carried out by using the driving device, which is more conducive to the rapid disassembly of the connecting shaft. At the same time, when installing, multiple connecting shafts on the support frame can be automatically installed simultaneously. The installation and disassembly efficiency are both relatively high, and a large amount of labor for manual disassembly is eliminated. The processing efficiency is higher, and the labor cost is saved. Description of the Drawings

[0019] Figure 2 is a schematic structural diagram of the driving device of the present utility model. Detailed Embodiments

[0020] As shown in the attached Figure 1-2 figures, the present utility model discloses a wall form support frame, which can be used for producing precast wall panels recorded in the patent with the publication number CN207453256U. The specific scheme of the present utility model includes a bottom frame 1, side forms 2 arranged around the bottom frame 1, a mold box 3 arranged inside the side forms 2, and a connecting shaft 5 arranged between the mold box 3 and the side forms 2. A driving device for driving the connecting shaft 5 to perform axial movement is provided on the connecting shaft 5.

[0021] A plurality of mold boxes 3 are arranged inside the chassis 1. The mold boxes 3 include corner mold boxes arranged at the four corners of the chassis 1 and side mold boxes arranged at the positions close to the edges in the middle of the chassis 1. Connecting shafts 5 are arranged on one side of each mold box 3 close to the side mold 2. Specifically, two connecting shafts 5 are provided on the corner mold box, respectively located on one side of the corner mold box close to the side mold 2, and one connecting shaft 5 is provided on the side mold box, located on one side of it close to the side mold 2.

[0022] The driving device includes a mounting plate 7 arranged on the side surface of the side mold 2 and a telescopic rod 8 with one end arranged on the mounting plate 7 through a rotating shaft. The other end of the telescopic rod 8 is connected to the connecting shaft 5 through a rotating shaft. Preferably, the number of telescopic rods 8 is two, symmetrically arranged on the left and right sides of the connecting shaft 5 respectively. The telescopic rod 8 is inclined. When it is in the shortened state, the connecting shaft 5 is located at the inner position and cooperates with the mold box 3. When it is in the extended state, the connecting shaft 5 is in the state of being pulled outwards. By using the telescopic movement of the telescopic rod 8, the connecting shaft 6 is driven to move along its axial position, so as to realize the installation and disassembly work of the connecting shaft 5 without manual operation.

[0023] Preferably, a limiting block 9 is arranged on the mounting plate 7 at the position on the side of the telescopic rod 8 close to the side mold 2. The surface of the limiting block 9 for contacting the telescopic rod 8 is an inclined surface. When the connecting shaft 5 cooperates with the mold box, the telescopic rod 8 abuts against the limiting block 9 to prevent the connecting shaft 5 from being too tightly fitted with the mold box and causing difficulty in disassembly.

[0024] A stabilizing block 6 is arranged on the side mold 2 at the position corresponding to the connecting shaft 5. A through hole is arranged on the stabilizing block 6. One end of the connecting shaft 5 passes through the through hole and then cooperates with the connecting hole on the mold box 3. After the wall panel is prefabricated, for the convenience of disassembly, the connecting shaft 5 includes a cylindrical section and a conical section arranged at one end of the cylindrical section. The telescopic rod 8 is connected to the cylindrical section, and the conical section passes through the through hole on the stabilizing block 6 and then cooperates with the mold box 3.

[0025] Preferably, the telescopic rod 8 is a cylinder or an electric push rod.

[0026] The utility model automatically realizes the movement of the connecting shaft 5 by using a mechanical structure. The multiple connecting shafts 5 on the support frame can act simultaneously, quickly completing the disassembly and installation work of the connecting shaft 5 without manual labor, greatly reducing the labor of workers and improving production efficiency.
