Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated buildings, in particular to a double-layer precast concrete beam-column mold. Background Technique

[0002] Prefabricated buildings have the characteristics of short construction period, energy conservation and environmental protection. It refers to a building assembled and installed at the construction site of a building, which is composed of the mutual combination of various precast concrete components, and then the precast concrete components are installed through a reliable connection method. During the production process of precast concrete components, concrete casting molds are usually used.

[0003] For example, in the design structure of a combined precast beam mold with the application publication number of "CN117863326A", positioning grooves are arranged on the substrate, and positioning blocks matching the positioning grooves are respectively arranged at the bottoms of the end molds and the intermediate connection molds, so as to facilitate the assembly of the mold body. After the installation is completed, adjacent connecting plates are connected by screws, and finally tightened with nuts, and the operation is convenient and simple, improving the assembly efficiency. However, the width of the above-mentioned mold is fixed and cannot be adjusted, so it is only applicable to the production of beam-columns with a fixed width, and the limitation is relatively high. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the width of the mold is fixed and cannot be adjusted, so it is only applicable to the production of beam-columns with a fixed width, and the limitation is relatively high, and a double-layer precast concrete beam-column mold is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design a double-layer precast concrete beam-column mold, including a frame and a cross beam. The middle part of the inner wall of the frame is fixedly connected with the cross beam. The lower end of the inner wall of the frame is provided with a precast concrete beam-column length adjustment structure. The left side of the outer wall of the frame is provided with a precast concrete beam-column width adjustment structure. The two sides of the inner wall of the frame are attached to straight plates.

[0007] Preferably, the precast concrete beam-column width adjustment structure includes a first toothed pulley. The outer wall of the first toothed pulley is meshed and connected with a second toothed pulley through a toothed belt. The right ends of the rotating parts of the first toothed pulley and the second toothed pulley are fixedly connected with double-headed studs. The outer walls of the two double-headed studs are rotationally connected with the frame through bearings. The outer walls of the two double-headed studs are threadedly connected with two threaded seats. The left end of the rotating part of the first toothed pulley is fixedly connected with a handle.

[0008] Preferably, the outer walls of multiple threaded seats are respectively fixedly connected with straight plates. The middle parts of the outer walls of the two double-headed studs are rotationally connected with the cross beam through bearings.

[0009] Preferably, the two precast concrete beam-column length adjustment structures include a housing. A spring is provided at the right end of the inner wall of the housing. The left end of the inner wall of the housing is slidably connected to a cross plate. The two ends of the spring are respectively fixedly connected to the housing and the cross plate. The lower end of the outer wall of the housing is threadedly connected to a threaded rod through a bearing, and the outer wall of the threaded rod is threadedly connected to a frame.

[0010] Preferably, the housing fits against the outer wall of the cross beam, and the cross plate fits against the outer wall of the straight plate.

[0011] The beneficial effect of the double-layer precast concrete beam-column mold proposed by the present utility model is as follows: Through the cooperation of the precast concrete beam-column width adjustment structure and the precast concrete beam-column length adjustment structure, rotating the two threaded rods respectively drives the housing to move upward between the straight plate and the cross beam. During this process, the end of the threaded rod can rotate through a bearing within the housing. Conversely, rotating the two threaded rods can respectively drive the housing to move downward between the straight plate and the cross beam. Rotating the handle drives the first toothed pulley to rotate. The rotation of the first toothed pulley drives the second toothed pulley to rotate through the toothed belt. Thus, the double-headed stud is respectively driven to rotate through the bearing within the frame and the cross plate by the first toothed pulley and the second toothed pulley. The rotation of the double-headed stud drives the two threaded seats to move relatively. Thereby, the straight plate is respectively driven to move relatively within the frame by the two threaded seats. In this way, the lengths and widths of the two casting grooves inside the frame can be adjusted, which is applicable to the production of beam-columns with different lengths and widths, reducing limitations.

The cross plate 203 is in contact with the outer wall of the straight plate 5.

[0021] Refer to the appendix Figures 1-4 And 6: The prefabricated concrete beam-column width adjustment structure 1 includes a first toothed pulley 101. The outer wall of the first toothed pulley 101 is meshed and connected to the second toothed pulley 102 through a toothed belt. The rotation of the first toothed pulley 101 can drive the second toothed pulley 102 to rotate through the toothed belt. The right ends of the rotating parts of the first toothed pulley 101 and the second toothed pulley 102 are fixedly connected with double-headed studs 103;

[0022] The outer walls of the two double-headed studs 103 are rotationally connected to the frame 3 through bearings. The rotation of the first toothed pulley 101 and the second toothed pulley 102 can respectively drive the double-headed studs 103 to rotate in the frame 3 through bearings. The outer walls of the two double-headed studs 103 are threadedly connected to the two threaded seats 104. The left end of the rotating part of the first toothed pulley 101 is fixedly connected with a handle 105.

[0023] Refer to the appendix Figures 1-3And 5: The two precast concrete beam-column length adjustment structures 2 include a housing 201. A spring 202 is provided at the right end of the inner wall of the housing 201. The elastic coefficient of the spring 202 can meet the working requirements according to actual needs. The left end of the inner wall of the housing 201 is slidably connected to a cross plate 203. The cross plate 203 can slide within the housing 201. A gasket is fixed at the connection between the cross plate 203 and the housing 201 to prevent concrete from entering the housing 201. Both ends of the spring 202 are fixedly connected to the housing 201 and the cross plate 203 respectively.

[0024] Working principle:

[0025] Double-layer precast concrete beam-column length and width adjustment work:

[0026] When pouring concrete beam-columns, spray an appropriate amount of release agent inside the frame 3 and lay the frame 3 down for use (the opening of the frame 3 faces upward). Subsequently, rotate the two threaded rods 204 to drive the housings 201 to move upward between the straight plate 5 and the cross beam 4 respectively. During this process, the end of the threaded rod 204 can rotate within the housing 201 through a bearing. Conversely, rotating the two threaded rods 204 can drive the housings 201 to move downward between the straight plate 5 and the cross beam 4 respectively. In this way, the length of the pouring groove inside the mold can be adjusted. Subsequently, rotate the handle 105 to drive the first toothed pulley 101 to rotate. The rotation of the first toothed pulley 101 drives the second toothed pulley 102 to rotate through a toothed belt. Thus, the double-headed stud 103 is driven to rotate within the frame 3 and the cross plate 4 through bearings respectively by the first toothed pulley 101 and the second toothed pulley 102. The rotation of the double-headed stud 103 drives the two threaded seats 104 at both ends to move relatively. Thus, the straight plate 5 is driven to move relatively within the frame 3 by the two threaded seats 104 respectively. In this way, the width of the two pouring grooves inside the mold can be adjusted. When the two straight plates 5 move relatively, they will push the two cross plates 203 to slide relatively within the housing 201, and at the same time compress the spring 202 to ensure that the cross plate 203 closely adheres to the outer wall of the straight plate 5 to prevent concrete leakage. When the adjustment of the width and length of the pouring groove inside the mold is completed, pour an appropriate amount of concrete into the two pouring grooves inside the frame 3 to start the work of pouring the beam-column. When the beam-column is cured, perform the opposite movement as above to move the housing 201, the cross plate 203, and the straight plate 5 away from the cured beam-column. Subsequently, open the box door installed at the upper end of the frame 3 to take out the cured beam-column. A gasket is fixed at the connection between the box door installed at the upper end of the frame 3 and the frame 3 to prevent concrete leakage.

[0027] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
