Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an infinitely telescopic diagonal bracing rod assembly for installing assembled prefabricated components. Background Art

[0002] During the main construction phase of residential building projects, prefabricated structures are often utilized. Temporary bracing for prefabricated structures has become an essential tool. However, currently available bracing rods are of a fixed length. Construction sites purchase bracing rods of varying lengths to meet installation requirements based on the dimensions specified in the installation drawings for components such as wall panels and prefabricated bay windows. However, some projects have multiple unit structures, and installation areas like prefabricated wall panels and prefabricated bay windows require a large number of bracing rods. External scaffolding uses climbing frames, and the guides of the climbing frames conflict with the bracing rod installation locations. To avoid this conflict, the prefabricated wall panel installation drawings are refined. Labor teams often simplify the process, but in some cases, wall panels are installed without matching the bracing rods with the required lengths specified in the detailed drawings. This leads to problems during construction management, with the bracing rods protruding when the climbing frames are raised to install the guides after prefabricated components are installed. This is because currently available bracing rods can only be fine-tuned using screws at both ends, resulting in a very limited range of extension and retraction. During construction, bracing rods of varying lengths and models are required to accommodate the different installation locations of prefabricated components, creating inconveniences during on-site construction and management.

[0003] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0005] To achieve the above-mentioned object, a stepless telescopic diagonal brace assembly for installing prefabricated components is provided, comprising:

[0006] A coarse adjustment support rod comprises a socket sleeve and a plug rod, one end of the plug rod is movably inserted into one end of the socket sleeve, the socket sleeve and the plug rod are respectively provided with a plurality of locking holes, the plurality of locking holes are spaced apart along the axial direction of the socket sleeve, and locking pins are detachably inserted into the locking holes of the socket sleeve and the plug rod;

[0007] A fine-tuning screw, wherein the other end of the socket sleeve and the other end of the plug rod are respectively formed with threaded holes, and one end of the fine-tuning screw is screwed into the threaded holes;

[0008] A draw hook for installing assembled prefabricated components is connected to the other end of the fine-tuning screw, and a locking sleeve for sealing the hook opening of the draw hook is screwed on the other end of the fine-tuning screw.

[0009] Furthermore, the multiple locking holes are arranged at equal intervals along the axial direction of the socket sleeve.

[0010] Furthermore, a support nut is screwed into the middle of the fine-tuning screw, and the support nut is supported by the end surface of the other end of the socket sleeve or the end surface of the other end of the connecting rod.

[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Reference Figures 1 to 4 As shown, the utility model provides an infinitely telescopic diagonal support rod assembly for installing assembled prefabricated components, comprising: a coarse adjustment support rod 1, a fine adjustment screw rod 2, and a draw hook 3.

[0022] Specifically, the coarse adjustment strut 1 includes a socket sleeve 11 and a splice rod 12. One end of the splice rod 12 is movably inserted into one end of the socket sleeve 11. The socket sleeve 11 and the splice rod 12 each have a plurality of locking holes. The plurality of locking holes are spaced apart along the axial direction of the socket sleeve 11. Locking pins are detachably inserted into the locking holes of the socket sleeve 11 and the splice rod 12.

[0023] As a preferred embodiment, a plurality of locking holes are arranged at equal intervals along the axial direction of the socket sleeve 11 .

[0024] In this embodiment, each coarse adjustment strut is equipped with two fine adjustment screws 2. Threaded holes are formed on the other end of the socket sleeve 11 and the other end of the plug rod 12. One end of the fine adjustment screw 2 is screwed into the threaded hole.

[0025] The hook 3 is connected to the other end of the fine-tuning screw 2. The other end of the fine-tuning screw 2 is screwed with a locking sleeve 31 for sealing the hook opening of the hook 3. Figure 3 and Figure 4 As shown, the hook 3 is used to install the assembled prefabricated component 4. In this embodiment, the assembled prefabricated component 4 is a prefabricated wall panel.

[0026] As a preferred embodiment, a support nut 21 is screwed into the middle of the fine-tuning screw 2. The support nut 21 is supported on the end surface of the other end of the socket sleeve 11 or the end surface of the other end of the plug rod 12.

[0027] In this embodiment, the outer wall of the locking sleeve 31 is connected to a toggle rod 32 .

[0028] As a preferred embodiment, there are two toggle rods 32. The two toggle rods 32 are respectively arranged on opposite sides of the locking sleeve 31. The two toggle rods are coaxially arranged.

[0029] The utility model is an infinitely telescopic diagonal brace assembly for installing assembled prefabricated components. When installing prefabricated bay windows, wall panels and other prefabricated components at an assembled construction site, the diagonal brace can be used to temporarily reinforce the prefabricated components. The length of the diagonal brace can be within a certain length range, realizing infinite telescopic changes.

[0030] This innovative, infinitely telescopic diagonal brace assembly for installing prefabricated components is constructed entirely of Q235 material, offering a balanced combination of strength, rigidity, and affordability. The assembly's telescopic length can be infinitely adjusted from 2 to 3.5 meters. This type of assembly can meet a wide range of diagonal brace requirements in prefabricated residential projects, eliminating the need to purchase diagonal braces of varying lengths to accommodate temporary reinforcements for components such as prefabricated wall panels and bay windows.

[0031] The connecting rod is made of Φ50×3mm round steel tube. It is 1470mm long and made of Q235 steel. It has eight 5mm diameter round holes (i.e., keyholes), spaced 100mm apart. At the end of the connecting rod is a 30mm diameter threaded hole that accepts a fine-tuning screw.

[0032] The socket is a Φ60 x 3mm round steel tube. The total length is 1500mm, and the material is Q235. It has eight 5mm diameter holes (i.e., keyholes), spaced 100mm apart. At the end of the socket is a 30mm diameter threaded hole that accepts a fine-tuning screw.

[0033] The total length of the fine-tuning screw is 433mm, the diameter is 30mm, and the material is Q235.

[0034] In order to achieve the purpose of infinite extension and retraction of the above-mentioned diagonal bracing rod within the range of 2 meters to 3.5 meters, the key points of operation are as follows:

[0035] First, according to the detailed installation drawings of PC prefabricated components, U-shaped steel anchor rings are embedded before pouring concrete on the floor slab. After the concrete reaches a strength of no less than 1.2MPa after pouring, the prefabricated wall panel installation ink lines and control ink lines are popped up on the floor slab.

[0036] Secondly, according to the drawing, the length of the infinitely telescopic diagonal brace assembly for installing prefabricated components is about 2.5 meters. Pull the plug rod out of the socket sleeve. When it is pulled to a length of about 2.5 meters, align it with the circular holes on the plug rod and the socket sleeve. Insert two pins in the circular holes to fix the plug rod and the socket sleeve so that their length remains unchanged.

[0037] Then, the prefabricated wall panels were hoisted with a lifting machine. The prefabricated wall panels were put into place according to the ink lines. The prefabricated wall panels were temporarily reinforced with infinitely telescopic diagonal bracing rods. The infinitely telescopic diagonal bracing rods were hooked with the anchor rings on the prefabricated wall panels and the U-shaped steel anchor rings embedded in the floor slabs through the hooks. The locking sleeves on the diagonal bracing rods were rotated so that the hooks could not be easily loosened from the wall panels and the U-shaped anchor rings, thus ensuring the stability of the temporary reinforcement of the wall panels.

[0038] Finally, the verticality of the prefabricated wall panels is calibrated according to the laser marking instrument. After the length of the diagonal bracing rod is fine-tuned to meet the installation verticality requirements of the prefabricated wall panels, the verticality locking sleeve is immediately tightened in reverse to prevent the fine-tuning screw, plug-in rod and socket sleeve from loosening, thereby ensuring the stability and verticality of the prefabricated wall panels.

[0039] The utility model is used for installing the infinitely telescopic diagonal brace assembly of assembled prefabricated components. The coarse-adjustment brace is used for coarse adjustment of the length, and then fine-adjustment is performed through the fine-adjustment screws at both ends, so that the length can be infinitely changed within the range of 2 meters to 3.5 meters. It can meet the temporary reinforcement of assembled prefabricated components in residential projects. It is not limited to the different lengths of diagonal braces on the market. Diagonal braces of different lengths can be produced, so that the product specifications are unified and batch production is possible. At the same time, it also achieves that when in use, fewer models need to be purchased, and one model can meet the installation requirements during installation, which is convenient for use and management.

[0040] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.
