Technical Field
[0001] The utility model relates to the technical field of construction, in particular to a reinforcing device for caulking of a masonry structure. Background Art
[0002] In the modern construction industry, the caulking of masonry structures needs to be reinforced during construction. In the masonry caulking reinforcement work, there is often residual sand between the wall joints. These sands not only affect the filling effect of special cement mortar, but may also cause problems such as wall cracking. It is necessary to clean the residual sand in the gap to prevent dust from adhering to the caulking. These sands will affect the beauty of the gap and the firmness of the mortar after filling.
[0003] At present, a smaller brush is used to clean the sand in the caulking, and some sand that is stuck needs to be pried off with a flat-blade screwdriver or other sharp tools, and then the mortar can be re-injected to ensure the integrity of the mortar inside the caulking after solidification, so that the caulking can adhere firmly to the masonry. The cleanliness of the caulking provides a guarantee for the subsequent caulking reinforcement of the masonry structure and determines the bonding strength of the subsequent grouting mortar.
[0004] Based on this, the utility model designs a reinforcement device for caulking of masonry structures to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a reinforcement device for caulking of masonry structures. The device can conveniently inject cement mortar in a grouting tube into the caulking by squeezing a push rod. The structural design of the mortar retaining member can block the injected cement mortar, and can also scrape off and clean old adhered sand and soil blocks inside the caulking through the sharp corners on the left and right sides. Moreover, the device has a detachable gun body and can be conveniently disassembled for cleaning. The device does not require other tools, thereby improving construction efficiency and ensuring project quality and safety.
[0006] The utility model is implemented as follows: a reinforcement device for caulking of a masonry structure, comprising:
[0007] Grouting cylinder, grout retaining piece and push rod;
[0008] The grouting cylinder is a hollow cylindrical structure with openings at both ends, and a holding rod is provided at the rear end of the grouting cylinder;
[0009] The front end of the grouting tube can be detachably mounted with a connecting tube, which is a conical guide tube with openings at both ends. The front and rear ends of the connecting tube are open, and the large end of the connecting tube is sealed and connected to the grouting tube;
[0010] The push rod is a straight rod, the front end of the push rod is a sealing piston, the rear end of the push rod is a handle, and the sealing piston is slidably arranged in the inner cavity of the grouting tube along the front-back direction;
[0011] The slurry retaining member is a groove structure with openings on the front end and the left and right sides and a closed rear end. The upper and lower sides of the slurry retaining member are trapezoidal flat plates of the same shape and size. The groove at the front end of the slurry retaining member is an inner retaining groove. The angle a between the left and right sides of the rear side of the slurry retaining member is an acute angle.
[0012] A connecting pipe is provided at the rear end of the slurry retaining member. The connecting pipe is a straight pipe with openings at both ends. The front end opening of the connecting pipe is arranged in the inner retaining groove on the front side of the slurry retaining member.

DETAILED DESCRIPTION
[0026] See also Figures 1 to 7 As shown, the utility model provides a reinforcement device for caulking of a masonry structure. In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings in the specification and specific implementation methods.
[0027] In a specific embodiment of the technical solution of the utility model:
[0028] It includes a grouting tube 1, a grouting block 2 and a push rod 3;
[0029] The grouting tube 1 is a hollow cylindrical structure with openings at both ends. A gripping rod 11 is provided at the rear end of the grouting tube 1. The gripping rod 11 is a long rod extending to the left and right sides. The two gripping rods 11 are symmetrically arranged outside the grouting tube 1. The two gripping rods 11 are arranged obliquely, such as Figure 1 As shown, the rear end is tilted, and the two holding rods 11 can be opened symmetrically so as to be convenient for bearing force, and can conveniently hold and bear force for operations such as prying, chiseling and shoveling.
[0030] The front end of the grouting tube 1 can be detachably mounted with a connecting tube 12, which is a conical guide tube with openings at both ends. The front and rear ends of the connecting tube 12 are open, and the large end of the connecting tube 12 is sealed and docked with the grouting tube 1; the connecting tube 12 is sealed and connected to the connecting pipe 21 through threads, and the connecting tube 12 is also sealed and connected to the grouting tube 1 through threads. The threaded connection is convenient for sealing and docking, and it is easy to disassemble and assemble. Such a structure that can be disassembled as a whole can be convenient for cleaning after the grouting is completed, and the threaded connection makes the thread fit more tightly, and the mortar is not easy to enter the thread and solidify, and it is easier to disassemble the entire device.
[0031] The push rod 3 is a straight rod, the front end of the push rod 3 is a sealing piston 31, the rear end of the push rod 3 is a handle, and the sealing piston 31 is slidably arranged in the inner cavity of the grouting tube 1 along the front-to-back direction; the sealing piston 31 is a rubber plug, and the sealing piston 31 and the grouting tube 1 are interference fit, which can make the sealing piston 31 and the grouting tube 1 fit tightly, and can perform grouting like a syringe.
[0032] The slurry retaining member 2 is a groove structure with openings on the front end and the left and right sides and a closed rear end. Figure 4 As shown, the side of the slurry retaining member 2 is in the shape of a U-shaped groove, the upper and lower sides of the slurry retaining member 2 are trapezoidal flat plates of the same shape and size, the groove at the front end of the slurry retaining member 2 is an inner retaining groove 22, and the angle a between the left and right sides of the rear side of the slurry retaining member 2 is an acute angle; the angle a does not exceed 50°, which is more acute, making it easier to pry out the original soil blocks or mortar blocks, and making cleaning more labor-saving and convenient. The slurry retaining member 2 is a trapezoidal groove as a whole, and the front end is narrow and the rear end is wide. Such a narrow front and wide rear structure can prevent the slurry injected into the wall crack from leaking out, and it is blocked by the baffle at the bottom of the rear inner retaining groove 22, while the wide front and narrow rear structure cannot completely block it, and there will be slurry leakage.
[0033] The left and right sides of the rear end, such as Figure 1 As shown, a pointed tip is formed, and the pointed tip is used to dig out impurities in the wall gap.
[0034] A connecting pipe 21 is provided at the rear end of the slurry retaining member 2. The connecting pipe 21 is a straight pipe with openings at both ends. The front end opening of the connecting pipe 21 is opened in the inner retaining groove 22 on the front side of the slurry retaining member 2. The rear end opening of the connecting pipe 21 is sealed and connected to the front end opening of the connecting tube 12.
[0035] The device also includes a T-tube connector 4, which is a T-shaped pipe. The front and rear ends of the vertical rod section of the T-tube connector 4 are open, and the front end opening of the T-tube connector 4 is a slurry outlet hole 41. The cross bar section of the T-tube connector 4 is a closed straight rod, and the cross bar section of the T-tube connector 4 is vertically arranged at the front end of its vertical rod section.
[0036] The slurry outlet hole 41 is provided at the front end of the crossbar section of the T-tube joint 4, and the rear end opening of the vertical pipe section of the T-tube joint 4 is connected to the front end opening of the connecting tube 12 by a threaded seal that can be separated. It can be easily replaced. When the slurry retaining member 2 is too wide to be plugged into the caulking in a smaller gap, the front side surface of the front crossbar of the T-tube joint 4 is arc-shaped, which can fit and seal smaller gaps, thereby adapting to more different masonry caulkings, and can also block smaller caulkings, so as to achieve the effect of inward grouting and shaping the mortar on the caulking surface.
[0037] It also includes an elbow joint 5 and a straight pipe joint 6, which are both replacement parts, and the elbow joint 5 or the straight pipe joint 6 is sealed and connected to the front end opening of the connection tube 12 through threads. It can be applied in different situations, especially the elbow joint 5. At the corner, when the grouting tube 1 is blocked and cannot be directly aligned, the elbow joint 5 can turn to grouting to avoid holes in the caulking.
[0038] When using, first put the parts as Figure 1 After the assembly is completed, the sharp corners of the left and right sides of the mortar retaining member 2 are extended into the masonry caulking, and the original soil blocks or mortar blocks in the gap are pried, chiseled, shoveled, etc. to keep the inside of the caulking clean.
[0039] Then remove the push rod 3 to expose the rear end opening of the grouting tube 1, then pour super-strong concrete into the grouting tube 1 from the rear end opening, and then insert the push rod 3 to make the sealing piston 31 tightly plugged with the inner wall of the grouting tube 1. The sealing piston 31 can be an elastic rubber plug.
[0040] The mortar retaining member 2 is inserted into the caulking of the masonry, and concrete is injected into the caulking from the connecting pipe 21 to the front end, and the concrete pattern is blocked and shaped by the mortar retaining member 2 to form a neat concrete caulking.
[0041] When the width of the caulking is small and the slurry retaining member 2 cannot extend into the interior, replace the joint, assemble the T-tube joint 4 at the front end of the connecting tube 12, and make the cross bar section at the front end of the T-tube joint 4 fit with the caulking, and then grouting. If the caulking is small, the cross bar at the front end of the T-tube joint 4 cannot extend into the caulking, and the T-tube joint 4 will be blocked outside the caulking to block the injected concrete mortar. If the caulking is slightly larger, the T-tube joint 4 can be inserted, and the concrete mortar in the caulking can be directly smoothed.
[0042] The elbow joint 5 and the straight pipe joint 6 can be installed at the front end of the connecting tube 12, and one of them can be replaced, which is convenient for deep-hole or internal curved hole grouting operation to be carried out inside the caulking, ensuring that there is no gap inside the caulking, and effectively improving the strength of the caulking repair.
[0043] For the sake of ease of description, the front end of the device refers to the end where the mortar is injected into the wall after the overall installation. The rear end refers to the end where the push rod 3 is handheld and pushed. The left and right ends refer to the left and right sides when the device is held horizontally and grouting is injected into the wall.
[0044] The orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings and is only for the convenience of describing the present invention and simplifying the description. It does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation.
