Description

Technical Field

[0001] The invention belongs to the technical field of building water and electricity installation, and particularly relates to a fixing device for a pre-buried beam-penetrating sleeve of a building and a construction method thereof. Background Art

[0002] The construction technology of buildings in my country is very advanced. Many water supply and electricity pipes have been changed from the original ground to the ceiling. This is not only convenient for later maintenance and replacement, but also does not damage the floor and provides better protection for the floor. However, it is necessary to place a sleeve in the beam first. The existing technology is either to weld the sleeve through the beam to the steel bar inside the beam, or to fix it with a fixed card on the beam slab with nails. However, due to the presence of steel bars and the narrow width of the beam, it is difficult to operate. This has also become a headache for many water and electricity construction workers. Summary of the invention

[0003] The invention provides a fast and efficient fixing device for pre-buried beam-penetrating sleeves in buildings and a construction method thereof.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] Preferably, it includes a pipe plug that is sealed and sleeved on both ends of the beam sleeve, the open end of the pipe plug is circumferentially provided with a split groove; the split groove on the open end of the pipe plug is provided with a locking mechanism that can control its size; the blocking end surface at the other end of the pipe plug and the corresponding beam side template intersection are connected and fixed by a provided convex column inserted into a provided concave hole.

[0006] Preferably, the open end of the pipe plug is circumferentially provided with N slit grooves; the N slit grooves are V-shaped.

[0007] Preferably, the locking mechanism provided at the split groove on the open end of the pipe plug is a clamp for fastening.

[0008] Preferably, a stopper is provided on the outer side of the split groove of the pipe plug to protect and prevent the clamp from falling off;

[0009] Preferably, a recessed circular hole is provided in the sealing end surface of the pipe plug at the intersection with the beam side formwork, and the center of the circular hole is co-centered with the pipe plug.

[0010] Preferably, the plugging end surface of the pipe plug at the intersection with the beam side formwork is provided with a recessed circular hole whose outer diameter is smaller than the inner diameter of the beam-penetrating sleeve; and the bottom of the recessed circular hole is closed.

[0011] Preferably, a fixing block which can be inserted into the recessed circular hole on the sealing end surface of the pipe plug is fixedly provided on the beam side template at the intersection with the pipe plug.

[0012] Preferably, a fixed nail hole is provided on the fixed block fixed at the intersection of the beam side formwork and the pipe plug.

[0013] Furthermore, the construction method is as follows:

[0014] a. First determine the length of the beam sleeve. The length of the beam sleeve is the width of the beam minus the thickness of the two fixed blocks fixed on the beam side template. After the material is laid, put the two pipe plugs on the two ends of the beam sleeve respectively, and put the clamps on the inside of the annular stoppers on the pipe plugs. According to the gap between the beam sleeve and the pipe plug, the clamp screws should be tightened a few more times if the gap is large, so as not to fall off. Set aside.

[0015] b. Before the carpenters install the beam side formwork, according to the requirements of the drawing, install the fixing block through the nail hole with self-tapping screws at the position of the beam side formwork that fixes the beam sleeve;

[0016] c. After the reinforcement workers put the bottom reinforcement of the beam into the beam, they put the beam-penetrating sleeve with pipe plugs on both ends next to the fixed block that has been fixed in the beam;

[0017] d. After the reinforcement worker has tied up all the reinforcement cages of the beam, he / she should push the two pipe plugs toward the inside of the beam sleeve with force, so that their length is less than the distance between the two fixing blocks fixed on the beam side formwork; pick up the beam sleeve, with the screws of the clamp facing upwards, and align the concave round holes on the plugs at both ends with the corresponding fixing blocks respectively, and push the pipe plugs toward the fixing blocks of the beam side formwork by hand until there is no gap between the pipe plugs and the beam side formwork, and tighten the clamps to lock the pipe plugs firmly on the beam sleeve;

[0018] e. After removing the template and before installing the sleeve, just knock off the sealing surface of the pipe plug with a hammer.

[0019] The locking mechanism of the open section of the pipe plug and the beam-penetrating sleeve of the present invention can also be realized in the following ways: one is to provide an internal thread on the inner wall of the open end of the pipe plug and an external thread on the outer wall of the beam-penetrating sleeve. When installing, the fixing block fixed on the template can be easily inserted into the recessed circular hole in the pipe plug by simply rotating the pipe plug; the second is to provide two small ears with through holes on the outer wall of the open end of the pipe plug, such as Figure 5 As shown, insert the butterfly screw into the through hole. The installation method is basically the same as above. Just tighten the butterfly screw.

[0020] The beneficial effects of the present invention are:

[0021] 1) The present invention can install the beam sleeve quickly and efficiently in a very short time. The beam sleeve does not need to be sealed with tape, and some auxiliary materials can be reused. It is economical and simple, and is firmly fixed without deviation.

[0022] 2) There are hundreds of different sizes of pipes. The open end of the pipe plug is circumferentially provided with a slit groove, which can be engaged with beam sleeves of different sizes under the action of the locking screw of the clamp, thereby tightening the beam sleeve; in addition, it can also prevent concrete from entering the beam sleeve through the gap between the beam sleeve and the pipe plug.

[0023] 3) The fixing block is fixed on the beam side formwork and does not need to be removed. It can be used until the floor is capped. In addition, this fixing block is inserted into the concave round hole of the plugging head, and there will be no contact with the concrete, so it is easier to remove the formwork.

[0024] 4) There is no uniform standard for the use of beam sleeves in construction sites across the country. Even for the same type of pipe, there are many different wall thicknesses. The recessed circular hole in the sealing end face of the pipe plug in this method matches the fixed block fixed on the beam side template, which unifies the size, facilitates large-scale production, and can also meet the installation and use of various types of beam sleeves. At the same time, this design can prevent concrete from entering the circular hole in the sealing end face of the pipe plug, and secondly, installation and disassembly are faster. The fixed block is fixed on the template and can be moved with the template, so it can be used next time, saving worry and effort.

[0025] The construction method is:

[0026] a. First determine the length of the beam sleeve. The length of the beam sleeve is the width of the beam minus the thickness of the two fixed blocks fixed on the beam side template. After the material is laid, put the two pipe plugs on the two ends of the beam sleeve respectively, and put the clamps on the inside of the annular stoppers on the pipe plugs. According to the gap between the beam sleeve and the pipe plug, the clamp screws should be tightened a few more times if the gap is large, so as not to fall off. Set aside.

[0027] b. Before the carpenters install the beam side formwork, according to the requirements of the drawing, install the fixing block through the nail hole with self-tapping screws at the position of the beam side formwork that fixes the beam sleeve;

[0028] c. After the reinforcement workers put the bottom reinforcement of the beam into the beam, they put the beam-penetrating sleeve with pipe plugs on both ends next to the fixed block that has been fixed in the beam;

[0029] d. After the reinforcement worker has tied up all the reinforcement cages of the beam, he / she should push the two pipe plugs toward the inside of the beam sleeve with force, so that their length is less than the distance between the two fixing blocks fixed on the beam side formwork; pick up the beam sleeve, with the screws of the clamp facing upwards, and align the concave round holes on the plugs at both ends with the corresponding fixing blocks respectively, and push the pipe plugs toward the fixing blocks of the beam side formwork by hand until there is no gap between the pipe plugs and the beam side formwork, and tighten the clamps to lock the pipe plugs firmly on the beam sleeve;

[0030] e. After removing the template and before installing the pipe, just knock off the sealing surface of the pipe plug with a hammer. BRIEF DESCRIPTION OF THE DRAWINGS
