Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a pre-buried device for observing the settlement of a building main body. Background Art
[0002] Settlement observation of buildings can directly reflect the amount, rate, and differential settlement of a construction project, playing a crucial role in project quality. However, due to the lack of suitable pre-embedded devices before pouring the main concrete structure, and the fact that traditional pre-embedded elbow settlement observation points compromise the formwork reinforcement, most buildings employ post-formwork drilling and post-embedded rebar. This post-embedded method not only tends to tilt the drill hole, but also easily hits the stressed rebar, making it difficult to guarantee the first-pass quality of the hole. Therefore, a pre-embedded device is urgently needed to improve efficiency and quality.
[0003] In the prior art, a Chinese utility model with publication number CN 206945010 U and publication date 2018.01.30 discloses a novel settlement observation point device, comprising an embedded part and an observation rod detachably connected to the embedded part. The embedded part comprises an embedded plate, the inner side of which is provided with two anchor bars arranged opposite to each other. The embedded plate is also provided with a threaded connection hole, and a sealing plate is provided at the inner opening of the threaded connection hole. The outer surface of the connection end of the observation rod is processed into an external thread that matches the threaded connection hole. Although this device can realize the embedded device for installing the observation rod, the positioning of the device is not accurate during installation and cannot be adjusted according to the template installation position. In addition, when pre-embedding, it is necessary to ensure that the embedded part is always on the side of the cast wall. The measurement steps are many and the position control is not accurate, which increases the difficulty of construction. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] like Figures 1-3 As shown, Example 1 is a pre-embedded device for observing the settlement of a building main body, comprising a base plate 1, a positioning column 2 provided on one side of the base plate 1, a mounting hole 3 provided on the base plate 1 for cooperating with the positioning column 2, and a connecting component for cooperating with a template provided on the other side of the base plate 1. This device has a simple structure and a fast installation speed. The positioning column 2 cooperates with the base plate 1, and the base plate 1 is connected to the wooden board through the connecting component. The pre-embedded position is accurately controlled without affecting the normal construction of the wall, reducing the difficulty of pre-embedding and making mass production faster. It can effectively save time and avoid the possibility of uncontrollable damage to the main structure caused by post-drilling that damages the concrete surface, tilts the drilling, or drills into stressed steel bars. It is firm and reliable.
[0023] In this embodiment, at least two reinforcing rods 4 are connected between the base plate 1 and the positioning posts 2. The reinforcing rods 4 are preferably threaded steel bars, one end of which is welded to the base plate 1, and the other end of the threaded steel pipe 5 is welded to the positioning posts 2. The threaded steel rods, the base plate 1, and the positioning posts 2 form a triangular structure, which increases the stability of the connection between the positioning posts 2 and the base plate 1.
[0024] like Figures 1-3 As shown in Example 2, a pre-buried device for observing the settlement of a building main body, the bottom plate 1 is a steel plate. The thickness of the steel plate is 2-5 mm, and the preferred thickness is 3 mm, which is convenient to obtain and ensures the stability of the bottom plate 1.
[0025] In this embodiment, the positioning column 2 includes a steel pipe 5, one end of which is welded to the base plate 1, and the other end of the steel pipe 5 is provided with a blocking plate 6. The blocking plate 6 is a steel plate, which is welded to the steel pipe. The steel pipe 5 is provided with an internal thread, and the inner diameter of the steel pipe 5 is the same as the diameter of the mounting hole 3. The observation rod is fixed in the steel pipe 5 through the mounting hole 3, which is convenient for fixation. When the wall is poured, the base plate 1 on one side of the mounting hole 3 is tightly fitted with the template, ensuring the sealing of the cavity between the mounting hole 3 and the steel pipe 5. At the same time, the blocking plate 6 is provided at the other end of the steel pipe 5 to prevent the poured concrete from entering the steel pipe 5 and blocking the steel pipe 5.
[0026] In this embodiment, the connection assembly includes at least two symmetrically arranged positioning nuts 7 and screws 8 that cooperate with the positioning nuts 7. The positioning nuts 7 are fixed to the side of the steel plate near the positioning column 2, and the screws 8 pass through the base plate 1 and are threadedly connected to the positioning nuts 7. The positioning nuts are galvanized hexagonal nuts. Four positioning nuts 7 are spaced apart from four reinforcing rods 4. The base plate 1 is provided with through holes that cooperate with the positioning nuts 7. The screws 8 pass through the through holes and cooperate with the positioning nuts 7 to fix the device on the formwork, ensuring the accuracy of the casting position of the device. At the same time, the base plate 1 is fitted with the formwork. The base plate 1 is tightly connected to the formwork through the screws 8 and the positioning nuts 7, which can achieve the sealing of the mounting holes 3 on the base plate 1, preventing the poured concrete from entering the positioning column 2, and at the same time avoiding the problem of drilling holes in the wall and affecting the stability of the wall.
[0027] The other structures are the same as those in Example 1.
[0028] like Figures 1-3 As shown in Example 3, a pre-embedded device for observing the settlement of a building structure, the connecting assembly includes at least two symmetrically arranged connecting bolts 9, which are threadedly connected to threaded holes provided on the base plate 1. The connecting bolts 9 are connected to the base plate 1 through the formwork, and can be used to fix the device to the formwork, thereby fixing the device and ensuring that the device remains in place.
[0029] The other structures are the same as those in Example 2.
[0030] Specifically, a 10cm*10cm*3mm steel plate was used; 8mm holes were drilled along the four corners 2cm from each side using an 8mm diameter cobalt-containing twist drill bit, and each hole was fully welded with a galvanized hexagonal nut with an internal thread diameter of M8; a 15mm diameter cobalt-containing twist drill bit was used to drill a 15mm hole along the center line; three 14mm diameter steel straight thread sleeves (single length 35mm) were selected and concentrically butt-welded to form a whole; one end of the whole sleeve was fully welded to the 15mm hole in the center of the steel plate, and the other end was welded to the 15mm hole in the center of the steel plate. The holes were fully welded with iron sheets to secure them tightly. Four 7cm-long, 8mm-grade, third-grade rebars were cut and symmetrically arranged on the four sides of the steel plate to effectively support and secure the steel plate and the steel pipe. All welds were placed on the same side of the steel plate, and depending on its storage age, either anti-rust paint or galvanizing was applied to ensure a rust-free appearance. The other side was tightly fitted to the wall stud-reinforced wooden formwork and secured with four M8*25mm (thread length) stainless steel hexagonal screws, effectively securing the embedded components horizontally and vertically. After the concrete pour was complete, the four hexagonal screws were removed to allow for smooth disassembly of the formwork. The nuts were approximately 6.7mm thick, the steel plate was approximately 3mm thick, and the wooden formwork was approximately 15mm thick, for a total thickness of approximately 25mm. This ensured easy installation and removal of the hexagonal screws without interference from the concrete pour. After formwork removal, the steel plate was flush and secure to the concrete surface. Settlement observation points could be secured with 14mm-diameter rebar threaded directly into the holes, or with 12mm-diameter round steel anchors and adhesive. A stainless steel brushed plate identification plate is made on the outside and is firmly fixed with four M8*10mm (thread length) stainless steel hexagonal screws.
[0031] Materials are readily available on-site, making fabrication and installation simple and time-saving. The fabrication process takes approximately 10 minutes, enabling faster mass production. This significantly reduces time and prevents uncontrolled structural damage caused by post-drilling, such as damage to the concrete surface, tilted drilling, or drilling into reinforced steel. The entire device is aesthetically pleasing, durable, and reliable.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
