Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete wallboard installation, in particular to a concrete wallboard clamping and fixing device. Background Art

[0002] Precast concrete wall panels are reinforced concrete plate-type components processed in precast plants (yards) or construction sites for building assembly. They are referred to as wall panels or sidings. The use of precast concrete wall panels to construct prefabricated large-panel buildings can improve the degree of factory and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the construction period.

[0003] When installing precast concrete wall panels, they need to be temporarily fixed by diagonal braces. The main function of the temporary diagonal braces is to prevent the precast concrete wall panels from overturning before the grouting material reaches the strength.

[0004] When the existing prefabricated concrete wall panel diagonal braces are in use, the screws at both ends are exposed to the outside for a long time, which makes it easy for impurities to adhere and rainwater to erode, and rust will appear on the surface of the screws, which will make subsequent disassembly difficult and not conducive to secondary recycling. Based on this, a concrete wall panel clamping and fixing device is provided. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figures 1 to 3 In the embodiment of the utility model, a concrete wall panel clamping and fixing device includes a diagonal brace assembly 1 for temporarily supporting and fixing the prefabricated wall panel 3 and the floor slab 4. The diagonal brace assembly 1 is composed of a middle connecting rod 101, a threaded rod 102, a connecting hook 103, and a blocking nut 104. The threaded rod 102 is symmetrically threadedly connected to the two ends of the middle connecting rod 101. Two thread grooves with opposite spiral directions are formed on the inner sides of the two ends of the middle connecting rod 101. The outer wall threads of the two threaded rods 102 match the two thread grooves respectively. The connecting hook 103 is fixed to one end of the threaded rod 102 away from the middle connecting rod 101. The blocking nut 104 is threadedly sleeved on the outside of the connecting hook 103 to block the opening of the connecting hook 103. A protective assembly 2 is arranged on the outside of the middle connecting rod 101. The protective assembly 2 is used to shield and protect the threaded rod 102 exposed outside the middle connecting rod 101.

[0026] The protection component 2 includes a shielding unit and a cleaning unit. The shielding unit is used to prevent external dust and rainwater from contacting the outer wall of the threaded rod 102. The cleaning unit is used to scrape and clean the solid impurities adhering to the outer side of the middle connecting rod 101.

[0027] The shielding unit includes a protective sleeve 201 and a sealing rubber ring 204;

[0028] The protective sleeve 201 is sleeved on both ends of the outer side of the middle connecting rod 101 and distributed on the outer side of the connecting hook 103, and is used to protect the connecting hook 103 from dust;

[0029] One end of the protective sleeve 201 is fixedly connected to the sealing nut 104, and the sealing rubber ring 204 is fixed to the inner side of the other end of the protective sleeve 201 and fits with the outer wall of the middle connecting rod 101 to block external rainwater;

[0030] The cleaning unit includes a connecting plate 202 and an annular shovel blade 203;

[0031] The connecting plate 202 is fixed to one end of the protective sleeve 201 away from the sealing nut 104, and multiple connecting plates 202 are arranged with the center of the protective sleeve 201 as the circumference. The annular shovel blade 203 is fixed to one end of the multiple connecting plates 202 away from the protective sleeve 201, and the inner side of the annular shovel blade 203 is tightly fitted with the outer side of the middle connecting rod 101. The annular shovel blade 203 is moved to push away solid impurities adhered to the outer side of the middle connecting rod 101, so as to prevent the solid impurities adhered to the outer side of the middle connecting rod 101 from causing wear to the sealing rubber ring 204.

[0032] In this embodiment: it should be supplemented that: the prefabricated wall 3 and the floor slab 4 are pre-buried with oblique support anchors, and the oblique support assembly 1 is hooked with the oblique support anchors through two connecting hooks 103, and then the plugging nut 104 is screwed to make it close to the connecting hook 103 to achieve the opening of the connecting hook 103. The connecting hook 103 maintains a stable connection state with the oblique support anchor. After the oblique support assembly 1 is installed, the verticality of the prefabricated wall 3 is measured by a level ruler, and the spacing between the two threaded rods 102 is adjusted by rotating the middle connecting piece 101, so as to adjust the verticality of the prefabricated wall 3, so as to achieve vertical support of the prefabricated wall 3;

[0033] During the use of the diagonal brace assembly 1, the protective sleeve 201 can shield the portion of the threaded rod 102 exposed outside the middle connecting rod 101, effectively preventing external dust from contacting and adhering to the outer wall of the threaded rod 102. At the same time, the sealing rubber ring 204 can prevent external rainwater from entering the space between the protective sleeve 201 and the outer wall of the middle connecting rod 101, thereby effectively preventing rainwater from contacting the threaded rod 102, thereby effectively preventing the threaded rod 102 from being eroded by rainwater.

[0034] In addition, when the prefabricated wall 3 is grouting, impurities are easily adhered to the outside of the middle connecting rod 101. If the sealing rubber ring 204 of the protective sleeve 201 contacts the impurities during movement, it is easy to cause excessive wear to the sealing rubber ring 204, thereby affecting the waterproof protection. Therefore, an annular shovel 203 is provided to scrape and clean the outer wall of the middle connecting rod 101, so that the surface where the middle connecting rod 101 contacts the sealing rubber ring 204 remains clean, thereby ensuring the long-term stable use of the sealing rubber ring 204.

[0035] Please refer to Figures 1 to 3, multiple groups of cleaning units are evenly arranged along the straight line direction of the middle connecting rod 101, and the multiple groups of cleaning units are welded and fixed to the outer side of the annular shovel blade 203 through the connecting plate 202;

[0036] The outer side of one end of the annular shovel blade 203 away from the connecting plate 202 is in an arc surface structure, which is used to form a blade surface structure.

[0037] In this embodiment: the arc surface structure of the annular shovel blade 203 can better remove impurities on the outer wall of the annular shovel blade 203;

[0038] Through the structural setting of multiple cleaning units, multiple cleaning operations can be performed. In addition, it should be noted that one end of the protective sleeve 201 is located at the front end of the sealing rubber ring 204 and is fixedly connected to a ring-shaped shovel 203 to ensure that the sealing rubber ring 204 will not be affected by external impurities.

[0039] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
