Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a telescopic joint cover member. Background Technique

[0002] A telescopic joint refers to a structural joint provided at an appropriate position along the construction joint direction of a building or structure to prevent building components from cracking or being damaged due to climate temperature changes, such as thermal expansion and contraction. The telescopic joint can divide building components above the foundation, such as walls, floors, roofs, etc., into two independent parts, enabling the building or structure to expand and contract horizontally along the long direction. In addition to preventing the building from cracking due to climate change, the telescopic joint can also meet the requirements of building waterproofing, fire prevention, etc. by installing a water stop belt and a fire prevention belt.

[0003] The existing construction joint cover plate is formed by bending the telescopic joint to leave a deformation space, and directly nailing the telescopic joint cover plate to the walls on both sides of the building telescopic joint with steel nails. Although this method can meet the deformation in the horizontal direction, it cannot meet the deformation in the vertical direction of the building. When the building undergoes vertical deformation, the telescopic joint cover plate will be pulled apart, affecting the aesthetics of the building and posing a risk of the telescopic joint cover plate falling off. For example, currently, Chinese Patent Application Publication No. CN105401662A discloses an aluminum alloy telescopic joint, which can only meet the deformation in the horizontal direction and cannot meet the deformation in the vertical direction of the building. Also, currently, Chinese Patent Application Publication No. CN101575878A discloses an external wall external thermal insulation telescopic joint structure, which can also only meet the deformation in the horizontal direction and cannot meet the deformation in the vertical direction of the building.

These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0033] Refer to Figures 1 to 9 An expansion joint cover plate member shown, including a first fixing piece assembly 100, a second fixing piece assembly 200 and an expansion joint cover plate 300.

[0034] The first fixing piece assembly 100 includes a plurality of first fixing pieces 110 which are spaced from top to bottom on the outer surface of the first wall 10 outside the expansion joint L, and the second fixing piece assembly 200 includes a plurality of second fixing pieces 210 which are spaced from top to bottom on the outer surface of the second wall 20 outside the expansion joint L.

[0035] The expansion joint cover plate 300 includes a cover plate body 310 and connecting edges 320 arranged on both sides of the cover plate body 310. The connecting edges 320 on both sides of the cover plate body 310 are respectively connected in cooperation with the first fixing edge 120 of the first fixing piece 110 and the second fixing edge 220 of the second fixing piece 210, so that the cover plate body 310 is movable in both the horizontal and vertical directions. When the building is subjected to external forces, there will be no risk of the expansion joint being cracked, deformed or dropped.

[0036] Preferably, the connecting edges 320 on both sides of the cover plate body 310 are respectively connected in cooperation with the first fixing edge 120 of the first fixing piece 110 and the second fixing edge 220 of the second fixing piece 210 by snap fits.

[0037] Specifically, the first fixing piece 110 includes a first horizontal edge 111, a first inclined edge 112, and a first fixing edge 120. The first horizontal edge 111 is connected to the first wall 10 by a fastener 40. A first screw hole 111a is provided on the first horizontal edge 111, and the fastener 40 is preferably a screw. One end of the first inclined edge 112 is connected to the first horizontal edge 111, and the other end is connected to one end of the first fixing edge 120. The first fixing edge 120 is arranged parallel to the surface of the first wall 10. A first clamping groove K1 is formed among the first fixing edge 120, the first inclined edge 112, and the first wall 10.

[0038] The second fixing piece 210 includes a second horizontal edge 211, a second inclined edge 212, and a second fixing edge 220. The second horizontal edge 211 is connected to the second wall 20 by a fastener 40. A second screw hole 211a is provided on the second horizontal edge 211, and the fastener 40 is preferably a screw. One end of the second inclined edge 212 is connected to the second horizontal edge 211, and the other end is connected to one end of the second fixing edge 220. The second fixing edge 220 is arranged parallel to the surface of the second wall 20. A second clamping groove K2 is formed among the second fixing edge 220, the second inclined edge 212, and the second wall 20. The connecting edges 320 on both sides of the cover plate body 310 are respectively connected in cooperation with the first clamping groove K1 and the second clamping groove K2. Since the fixing piece is inside the cover plate and the expansion joint cover plate 300 is snap - covered, after the installation of the expansion joint cover plate 300 is completed, there are no nails on the surface, the surface flatness is better, and the overall effect is more beautiful.

[0039] The connecting edges 320 on both sides of the cover plate body 310 in this embodiment include vertical edges 321 and horizontal edges 322 that are folded towards the expansion joint direction. One end of the vertical edge 321 is connected to the cover plate body 310, and the other end is connected to one end of the horizontal edge 322. The horizontal edge 322 is connected to the first card slot K1 and the second card slot K2 in a mating manner. In order to further fix and mate the horizontal edge 322 with the first card slot K1 and the second card slot K2, a fixing auxiliary structure 323 is provided at one end of the horizontal edge 322 away from the vertical edge 321. The fixing auxiliary structure 323 in this embodiment is an inverted hook edge structure. Of course, rubber can also be used as the fixing auxiliary structure, as long as it can assist in further fixing and mating the horizontal edge 322 with the first card slot K1 and the second card slot K2.

[0040] To ensure the firmness of the expansion joint cover plate 300, the distance between two adjacent upper and lower fixing pieces is controlled within 500 mm. The deviation of all the first fixing pieces 110 on the first fixing piece assembly 100 in the longitudinal direction relative to the same reference line should not exceed 5 mm, and the deviation of all the second fixing pieces 210 on the second fixing piece assembly 200 in the longitudinal direction relative to the same reference line should not exceed 5 mm. It can also be that one of the connecting edges 320 on both sides of the cover plate body 310 is fixed to the wall with structural adhesive 30 after installation.

[0041] The assembly process of the present utility model is as follows:

[0042] 1) First, level the surface of the building to basically ensure the flatness of the components on both sides of the expansion joint L;

[0043] 2) Use an electric drill to drill holes on the first wall 10 and the second wall 20 on both sides of the building expansion joint L, and use expansion nails to firmly fix the first fixing piece 110 and the second fixing piece 210, and apply structural adhesive to prevent the fixing pieces from rotating;

[0044] 3) First, buckle one side of the expansion joint cover plate 300 into the first card slot K1 formed by the first fixing piece assembly 100 and make it reach the deepest point of insertion, then buckle the other side of the expansion joint cover plate 300 into the second card slot K2 formed by the second fixing piece assembly 200, and gently tap the side of the expansion joint cover plate 300 to make the insertion depths on both sides of the expansion joint cover plate 300 basically the same;

[0045] 4) Apply structural adhesive 30 on one side of the expansion joint cover plate 300 to prevent the expansion joint cover plate 300 from moving laterally and form a self-locking structure. However, adhesive can only be applied on one side for fixation, and not on both sides, as applying adhesive on both sides will cause the expansion joint cover plate 300 to lose its movable space.

[0046] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of this application. At the same time, it should be understood that for the sake of convenience in description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0047] In the description of this application, it should be understood that the orientation or positional relationships indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing this application and simplifying the description. Without contrary statements, these orientation terms do not indicate or imply that the devices or elements referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the protection scope of this application; the orientation terms "inside, outside" refer to inside and outside the contours of the respective components themselves.

[0048] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationships between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0049] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of differentiating the corresponding components. Without additional statements, these words have no special meanings. Therefore, they should not be construed as limiting the protection scope of this application.

[0050] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
