Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, and in particular to a vibration damping component for a pump pipe that passes through a floor. Background Technology

[0002] In construction projects, especially high-rise building construction, pump pipes penetrating floor slabs experience prolonged irregular shaking during concrete pumping, which can cause fatigue damage and cracks in the floor slab concrete, thus affecting the construction quality of the floor slab concrete.

[0003] Currently, to address the existing problems with pump pipes penetrating floor slabs, the following two fixing methods are used to fix pump pipes penetrating floor slabs in buildings:

[0004] The first method, a traditional and still widely used technique, involves directly using square timber to make wooden wedges, which are then inserted around the pump pipe for fixation. While simple to process and convenient to use, these wedges are prone to loosening and falling off due to vibration during use, rendering them ineffective for fixing the pump and also providing poor vibration damping.

[0005] The second method involves assembling and fixing the pump pipe using specially made components (such as an inflatable cushion with an external power supply, adjustable fasteners, and adjustable supports), which can achieve a certain vibration reduction effect. However, for high-rise buildings with many floors, a large number of customized components are required, making the operation complex and the cost high.

[0006] In view of the shortcomings of the existing methods for fixing pump pipes that penetrate floor slabs, those skilled in the art have been searching for solutions. Utility Model Content

[0007] The purpose of this utility model is to provide a vibration damping component for pump pipes passing through floors, so as to solve the problems of poor vibration damping effect, complicated construction operation and high cost of the existing fixing method for pump pipes passing through floors.

[0008] To solve the above-mentioned technical problems, this utility model provides a vibration damping component for a pump pipe passing through a floor. The vibration damping component for a pump pipe passing through a floor includes: two vibration damping sub-units and at least two fasteners. The two vibration damping sub-units are symmetrically and detachably installed on the outer edge of the floor slab with the reserved pump pipe hole. The fasteners fasten the two symmetrically arranged vibration damping sub-units so as to fasten the pump pipe to be damped in the fastening space formed by the symmetrical arrangement of the two vibration damping sub-units.

[0009] Each vibration damping subunit includes: a base, a vibration damping layer set inside the base, and a cable fixing bracket fixed on the base. The base is detachably fitted onto the outer edge of the floor slab with the reserved pump pipe hole. The two cable fixing brackets together form a fastening space for placing the pump pipe.

[0010] Optionally, in the vibration damping component of the through-floor pump pipe, each vibration damping subunit further includes: a first bolt assembly and a second bolt assembly, wherein the base and vibration damping layer are fastened to the cable fixing frame based on the first bolt assembly, and the base and vibration damping layer are fastened to the floor slab based on the second bolt assembly.

[0011] Optionally, in the vibration damping component of the through-floor pump pipe, the first bolt assembly includes: a first bolt and a nut adapted to the first bolt; the second bolt assembly includes: a second bolt and a nut adapted to the second bolt.

[0012] Optionally, in the vibration damping component of the through-floor pump pipe, the base includes a body and a first bolt hole and a second bolt hole formed on the body to accommodate the first bolt assembly and the second bolt assembly.

[0013] Optionally, in the vibration damping component of the through-floor pump pipe, the base is a channel steel, and the opening of the channel steel is set away from the cable fixing frame.

[0014] Optionally, in the vibration damping component for the pump pipe passing through the floor, the cable fixing frame includes: a base plate and a semi-circular frame disposed on the base plate.

[0015] Optionally, in the vibration damping component of the through-floor pump pipe, the base plate is provided with a second bolt hole adapted to the second bolt assembly, and the edge of the frame is provided with a first bolt hole adapted to the first bolt assembly.

[0016] Optionally, in the vibration damping component of the through-floor pump pipe, the vibration damping layer is a rubber layer.

[0017] Optionally, in the vibration damping component of the through-floor pump pipe, the thickness of the vibration damping layer is 20mm or more.

[0018] Optionally, in the vibration damping component of the through-floor pump pipe, the fasteners are bolts and nuts adapted to the bolts.

[0019] In the vibration damping component for through-floor pump pipes provided by this utility model, there are two vibration damping sub-units and at least two fasteners. The two vibration damping sub-units are symmetrically and detachably installed on the outer edge of the floor slab with the reserved pump pipe hole. The fasteners fasten the two symmetrically arranged vibration damping sub-units to secure the pump pipe to be damped in the fastening space formed by the symmetrical arrangement of the two vibration damping sub-units. Each vibration damping sub-unit includes: a base, a vibration damping layer disposed on the inner side of the base, and a cable fixing bracket fixed on the base. The base is detachably sleeved on the outer edge of the floor slab with the reserved pump pipe hole. The two cable fixing brackets together form the fastening space for placing the pump pipe. By setting a vibration damping layer on the inner side of the base, hard contact between the base and the floor slab is avoided, reducing friction and stress between them. This prevents the pump pipe from causing fatigue damage and cracks in the floor slab concrete due to long-term irregular shaking during concrete pumping, thus improving the vibration damping effect. In addition, the vibration damping component of this invention can be assembled using waste and reusable materials on the construction site, and can be reused. The construction operation is simple, convenient, and practical, effectively reducing construction costs. Attached Figure Description

[0024] The vibration damping component for through-floor pump pipes proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of a utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In utility models, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.

[0029] Please refer to Figure 1 and Figure 2 The vibration damping component for the through-floor pump pipe includes two vibration damping sub-units and at least two fasteners 7. The two vibration damping sub-units are symmetrically and detachably installed on the outer edge of the floor slab 2 (i.e., the floor structure slab) with the reserved pump pipe hole. The fasteners 7 fasten the two symmetrically arranged vibration damping sub-units to secure the pump pipe 1 to be damped within the fastening space formed by the symmetrical arrangement of the two vibration damping sub-units. Each vibration damping sub-unit includes a base 3, a vibration damping layer 4 disposed inside the base 3, and a cable fixing bracket 5 fixed to the base 3. The base 3 is detachably fitted onto the outer edge of the floor slab 2 with the reserved pump pipe hole. The two cable fixing brackets 5 together form the fastening space for placing the pump pipe. Therefore, the vibration damping component for the through-floor pump pipe of this invention is specifically installed in the reserved pump pipe hole on the floor slab 2, thus serving as a vibration damping medium between the floor slab 2 and the pump pipe 1.

[0030] Preferably, the fastener 7 is a bolt and a nut adapted to the bolt. Here, the bolt is a relatively long bolt, thereby providing adjustment space for adjusting the fastening space and adapting to pump pipes of different sizes.

[0031] Furthermore, each vibration damping subunit also includes: a first bolt assembly 8 and a second bolt assembly 6, wherein the base 3 and the vibration damping layer 4 are fastened to the cable fixing frame 5 based on the first bolt assembly 8, and the base 3 and the vibration damping layer 4 are fastened to the floor slab 2 based on the second bolt assembly 6.

[0032] The first bolt assembly 8 includes a first bolt and a nut adapted to the first bolt; the second bolt assembly 6 includes a second bolt and a nut adapted to the second bolt.

[0033] Accordingly, in this embodiment, the base 3 includes a body and a first bolt hole and a second bolt hole adapted to the first bolt assembly 8 and the second bolt assembly 6. In this embodiment, the base 3 is preferably a channel steel, with the channel steel opening facing away from the cable fixing frame 5; the vibration damping layer 4 is a rubber layer, and the thickness of the vibration damping layer 4 is preferably 20mm or more, which is sufficient to avoid hard contact between the base 3 and the floor slab 2, alleviate friction and stress between the two, and prevent the pump pipe through the floor slab from causing fatigue damage to the floor slab concrete and causing floor slab cracks due to long-term irregular shaking in the up-down, left-right, and back-and-forth motion during concrete pumping, thereby improving the vibration damping effect of the vibration damping component.

[0034] like Figure 1 and Figure 1 As shown, the cable fixing bracket 5 includes: a base plate and a semi-circular frame disposed on the base plate. The base plate has second bolt holes adapted to the second bolt assembly 6, and the edge of the frame has first bolt holes adapted to the first bolt assembly 8. It is understood that the frame can also be arc-shaped, as long as it fits snugly against the pump pipe 1 placed in the cable fixing bracket 5 to achieve a better fastening effect.

[0035] Specifically, the structure formed by the two cable fixing brackets and fasteners 7 is similar to the existing component with a base cable fixing clamp. Therefore, the cable fixing brackets and fasteners in the vibration damping component of this utility model do not need to be specially customized. Finished products can be purchased in advance according to the model to be used later. After use, they can be disassembled and reused, effectively reducing construction and material costs.

[0036] In addition, the base of the vibration damping component of this utility model can be made by cutting two sections of scrap channel steel from the construction site according to the reserved pump pipe hole size, and lining it with scrap rubber of more than 20mm as a vibration damping layer, which further reduces the manufacturing cost. The bottom of the base is tightly pressed against the bottom of the floor slab, and the top of the base is connected to the channel steel and the rubber layer by a second bolt assembly 6 to prevent the rubber layer from falling off during the pumping process of the pump pipe. One side of the two cable fixing brackets is fastened and connected by fasteners, and the other side is fixed to the base on the corresponding side by a first bolt assembly 8.

[0037] It is understood that the above examples are merely examples listed to better understand the technical solutions of the embodiments of this application, and are not intended to be the only limitation on the embodiments.

[0038] Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by this application.

[0039] The vibration damping component for through-floor pump pipes provided by this utility model has at least the following beneficial effects:

[0040] 1) Vibration damping components avoid hard contact between the base and the floor slab by setting a vibration damping layer on the inner side of the base, thereby reducing friction and stress between the two. This prevents the pump pipe from causing fatigue damage to the floor slab concrete and causing floor slab cracks due to long-term irregular shaking in the pumping process, thus improving the vibration damping effect.

[0041] 2) Vibration damping components can be assembled using waste and reusable materials on the construction site, and can be reused repeatedly. The construction operation is simple, convenient and practical, effectively reducing construction costs.

[0042] Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Therefore, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model also intends to include these modifications and variations.
