[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 - Figure 4 As shown, the thickness control device of the cast-in-place layer of the composite slab of this embodiment includes a distance measuring mechanism 1 and a fixing mechanism 2, the fixing mechanism 2 is used to fix the distance measuring mechanism 1, the distance measuring mechanism 1 includes a mold 11, a side plate 12, a cross bar 14, a vertical bar 15, a fixing plate 16 and an adjusting component 17, one end of the fixing mechanism 2 is fixed to the bottom of the mold 11, and the other end of the fixing mechanism 2 is fixed to the side plate 12; a groove is provided at the top of the side plate 12, one end of the cross bar 14 is rotatably connected to the connecting column 13, and the two ends of the connecting column 13 are detachably connected to the side wall of the groove, and a positioning plate 131 is clamped on the inner side of the side plate 12, and the positioning plate 131 is tightly abutted against the connecting column 13 and the cross bar 14; the top of the vertical bar 15 passes through the other end of the cross bar 14, and the bottom of the vertical bar 15 is fixed to the fixing plate 16; the adjusting component 17 is arranged inside the cross bar 14 and meshes with one end of the vertical bar 15.

[0025] First, the side plate 12 is fitted with the mold 11, and the cross bar 14 is rotated to make it flat and horizontal. The positioning plate 131 will rely on the side plate 12 as a support point to keep the cross bar 14 immobile, and then adjust the adjustment component 17 to make the vertical rod 15 move downward. When the required movement is achieved, the fixing plate 16 will be inside the mold 11.

[0026] Furthermore, a laser instrument 161 is fixed to the side wall of the fixing plate 16 .

[0027] Furthermore, a sensor 162 is fixed on the top of the fixing plate 16 , and an early warning device 163 is fixed on the top of the sensor 162 .

[0028] Furthermore, the laser instrument 161 is electrically connected to the input end of the sensor 162 , and the early warning device 163 is electrically connected to the output end of the sensor 162 .

[0029] Furthermore, a cavity is provided inside the cross bar 14, and an adjustment component 17 is provided in the cavity. The adjustment component 17 includes a gear 171, a limit rod 172, a spring 173 and a fixing rod 174. The center of the gear 171 is rotatably connected to the side wall of the cavity, and one end of the gear 171 located on the outside of the cavity is meshed with the vertical rod 15; one end of the gear 171 located on the inside of the cavity is clamped with one end of the limit rod 172, the other end of the limit rod 172 is fixed to one end of the spring 173, and the other end of the spring 173 is fixed to the inner wall of the cavity; the inner end of the fixing rod 174 passes through the cross bar 14 and is fixed to the outer wall of the limit rod 172, and a sliding groove matching the fixing rod 174 is provided on the outer wall of the cross bar 14.

[0030] During the rotation of gear 171, the limit rod 172 will continuously engage with the gear 171 under the action of spring 173, so that after the gear 171 rotates, the vertical rod 15 can remain in place and ensure that there will be no shaking during the production process, which will lead to inconsistent concrete pouring height. In addition, when it is necessary to release the fixation of the vertical rod 15, by pushing the fixing rod 174, the limit rod 172 will no longer be engaged with the low gear 171, thereby completing the fixation release of the vertical rod 15.

[0031] Furthermore, the fixing mechanism 2 includes a plurality of insert rods 21 and a locking plate 22, one end of the plurality of insert rods 21 is fixed to the bottom side wall of the mold 11, the other end of the plurality of insert rods 21 passes through the side plate 12 and extends to the outside of the side plate 12, a card slot is opened on the top of the insert rods 21, and the locking plate 22 is card-engaged with the plurality of card slots.

[0032] When the side panel 12 is in the process of fitting with the mold 11, it is necessary to connect and pass the side panel 12 with the insertion rod 21 to pre-position it. At this time, the locking plate 22 is inserted into the groove of the insertion rod 21 so that it is against one side of the side panel 12 and fixed. This can effectively fix the position of the side panel 12 and the mold 11 to prevent the side panel 12 from moving or deviating from the predetermined position during the manufacturing process, thereby ensuring the accurate shape of the composite panel. When the side panel 12 needs to be removed from the insertion rod 21, the locking plate 22 is moved upward so that the side panel 12 is not restricted. At this time, the side panel 12 can be pushed until it is detached from the insertion rod 21.

[0033] The working principle of the utility model is:

[0034] By rotating the cross bar 14 to make it horizontal, the gear 171 is rotated at this time to make the vertical bar 15 move downward. After the movement is required, the fixed plate 16 will be inside the mold 11. In this way, during the production, through the laser instrument 161 installed on the fixed plate 16, if the expected height is exceeded during the pouring process, the sensor 162 will receive the command and send an instruction to the early warning device 163 to make it sound to remind the operator to make adjustments, so as to correct the error in time and ensure the quality of the composite plate. During the rotation of the gear 171, the limit rod 172 will continuously engage the gear 171 under the action of the spring 173. In this way, after the gear 171 rotates, the vertical bar 15 can remain in place and not move. During the production process, there will be no shaking, ensuring the consistent pouring height;

[0035] The side panel 12 is connected and passed through the insertion rod 21 to be pre-positioned. At this time, the locking plate 22 is inserted into the groove of the insertion rod 21 to make it abut against one side of the side panel 12 and fix the side panel 12. This can effectively fix the position of the side panel 12 and the mold 11, prevent the side panel 12 from moving or deviating from the predetermined position during the production process, and ensure the accuracy of the shape of the composite panel.
