Description

Technical Field

[0001] This utility model belongs to the technical field of anti-sill clamps, specifically a clamp for roof guide wall anti-sills. Background Technology

[0002] In building construction, roof guide walls and inverted sills are an important component of the roof structure, mainly used for waterproofing, preventing falls, and enhancing the overall integrity and aesthetics of the roof.

[0003] Traditional inverted curb construction typically uses wooden or steel formwork for support before pouring concrete to shape it. However, the formwork is prone to displacement or deformation during the concrete pouring process, leading to dimensional deviations in the inverted curb and affecting the construction quality.

[0004] For example, Chinese invention patent application CN118815147A, published on October 22, 2024, discloses a construction method for a precast beam clamp that also serves as a fastener for a roof guide wall and anti-sill. The method includes: detailed design of the roof slope direction, gradient, and flashing height; positioning of the parapet wall guide wall and the anti-sill of the wall extending above the roof; setting up wooden formwork, internally supported by precast concrete blocks, with timber as secondary joists at the top and bottom, and small square steel as secondary back braces in the remaining parts, and temporary support and calibration using short steel bars; fixing the wooden formwork with the precast beam clamp and performing secondary calibration; calibrating and fixing the precast beam clamp to the roof slab reinforcement; and acceptance before pouring.

[0005] In the aforementioned prior art, prefabricated beam clamps are used to reinforce the parapet wall guide wall by inverting and fastening the formwork. However, the clamps are standardized designs, which are difficult to adapt to the different thicknesses and heights of the roof guide wall. Furthermore, the steel bars are welded to the roof, making it difficult to reuse them efficiently.

[0006] Therefore, how to effectively solve the problem of the limited applicability and difficulty in efficient turnover of clamps used for roof guide walls and inverted curbs is an urgent technical issue that needs to be addressed. Utility Model Content

[0007] To address the shortcomings in the aforementioned background technology, this utility model proposes a clamp for roof guide wall inverted sills, which solves the problems of limited applicability and difficulty in efficient turnover of clamps used for roof guide wall inverted sills.

[0008] The technical solution of this application is as follows:

[0009] A clamp for a roof guide wall sill includes an inner pressure plate, a top pressure plate, and an outer pressure plate. Pressure plate one and pressure plate two are adjustablely connected, while pressure plate three is fixedly connected to pressure plate two. An extension pressure plate is adjustablely connected to pressure plate three, and an angle-adjustable support component is connected to pressure plate one. The adjustable connection between pressure plate one and pressure plate two allows for adaptation to different sill thicknesses, eliminating the need for customized clamps of different specifications. The extension pressure plate is telescopically adjustable, accommodating guide wall sills of varying heights and reducing replacement frequency. The inner pressure of pressure plate one, the top pressure of pressure plate two, and the outer pressure of pressure plate three effectively resist lateral pressure during concrete pouring, preventing formwork bulging or displacement. Pressure plate three and the extension pressure plate ensure uniform stress on the outer formwork, avoiding localized deformation. The support component flexibly adjusts its angle according to the roof slope, providing stable oblique support and further reducing vibration displacement during sill pouring.

[0010] Furthermore, a sleeve is connected to the top of the pressure plate, the inner wall of the sleeve is in contact with the outer wall of the pressure plate, and both the sleeve and the pressure plate are provided with several width adjustment grooves and are positioned by width adjustment pins.

[0011] Furthermore, the extended pressure plate is hollow, and the inner wall of the extended pressure plate is fitted with the outer wall of the pressure plate three. Both the extended pressure plate and the pressure plate three are provided with several height adjustment grooves and are positioned by height adjustment pins.

[0012] Furthermore, the cross-sections of the pressure plate one, pressure plate two, and pressure plate three are right-angled trapezoids.

[0013] Furthermore, the extended pressure plate is provided with an opening on the side and top surface of the right-angled side, and the right-angled sides of the extended pressure plate and the pressure plate three are arranged on the same straight line.

[0014] Furthermore, both the width adjustment pin and the height adjustment pin are wedge-shaped. By adjusting the insertion depth of the wedge-shaped pin, continuous and precise adjustment can be achieved to adapt to subtle differences in the thickness or height of the anti-sill.

[0015] Furthermore, both the width adjustment pin and the height adjustment pin are provided with auxiliary holes for installing ropes.

[0016] Furthermore, the supporting component includes a reinforcing rod, one end of which is hinged to a pressure plate and the other end is adjustablely connected to a pre-installed component on the roof.

[0017] Furthermore, the reserved component includes an inverted L-shaped component embedded in the roof, and the end of the reinforcing rod near the roof is provided with a strip hole, and one side of the strip hole is provided with several locking teeth that cooperate with the inverted L-shaped component for blocking.

[0018] Furthermore, the reserved component includes a perforated steel bar embedded in the roof, and the end of the reinforcing rod near the roof is provided with several holes, which are positioned with the perforated steel bar by pins.

[0019] The specific beneficial effects of this utility model include:

[0020] 1. The pressure plate one and pressure plate two of this utility model are adjustable to adapt to different thicknesses of the anti-sill, eliminating the need for customized clamps of different specifications. The extended pressure plate is telescopic and adjustable, compatible with guide wall anti-sills of different heights, reducing the frequency of replacement. The pressure plate one presses inward, the pressure plate two presses upward, and the pressure plate three presses outward, effectively resisting the lateral pressure of concrete pouring and preventing the formwork from bulging or shifting. The pressure plate three and the extended pressure plate ensure that the outer formwork is subjected to uniform force, avoiding local deformation. The support components can flexibly adjust the angle according to the roof slope, providing stable oblique support and further reducing vibration displacement during the anti-sill pouring process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1: A clamp for a roof guide wall sill, such as... Figure 1 , Figure 2 As shown, the structure includes a pressure plate 1 on the inner side of the sill, a pressure plate 2 on the top of the sill, and a pressure plate 3 on the outer side of the sill. Pressure plate 1 and pressure plate 2 are adjustablely connected, and pressure plate 3 is fixedly connected to pressure plate 2. An extension pressure plate 4 is adjustablely connected to pressure plate 3. An adjustable-angle support component is provided between pressure plate 1 and the roof. The adjustable connection between pressure plate 1 and pressure plate 2 allows for adaptation to different sill thicknesses, eliminating the need for customized clamps of different specifications. The extension pressure plate 4 is telescopically adjustable, compatible with guide wall sills of different heights, reducing replacement frequency. The internal pressure of pressure plate 1, the top pressure of pressure plate 2, and the external pressure of pressure plate 3 form a three-dimensional fixing system, effectively resisting the lateral pressure of concrete pouring and preventing formwork bulging or displacement. Pressure plate 3 and the extension pressure plate 4 ensure uniform stress on the outer formwork, avoiding local deformation. The support component flexibly adjusts its angle according to the roof slope, providing stable oblique support and further reducing vibration displacement during sill pouring.

[0040] Based on the above implementation method, a sleeve 5 is fixedly connected to the top of the pressure plate 1. The inner wall of the sleeve 5 is in contact with the outer wall of the pressure plate 1. Both the sleeve 5 and the pressure plate 1 are provided with a number of width adjustment grooves 7 and are positioned by width adjustment pins 6. The sleeve 5 drives the pressure plate 1 to move on the pressure plate 2, so as to adjust the distance between the pressure plate 1 and the pressure plate 3 according to the thickness of the guide wall countersill.

[0041] Based on the above implementation method, the extended pressure plate 4 is hollow, the inner wall of the extended pressure plate 4 is fitted with the outer wall of the pressure plate 3, the extended pressure plate 4 is sleeved on the outside of the pressure plate 3 and moves up and down, both the extended pressure plate 4 and the pressure plate 3 are provided with a number of height adjustment grooves 10 and are positioned by height adjustment pins 11, the distance between the pressure plate 3 and the extended pressure plate 4 can be adjusted according to the length and height of the template, and the fit with the guide wall reverse slope template is improved.

[0042] Based on the above implementation method, the cross-sections of the pressure plate 1, pressure plate 2, and pressure plate 3 are right-angled trapezoids, and the right-angled sides are attached to the outer wall of the guide wall reverse slope template.

[0043] Based on the above embodiment, the extended pressure plate 4 is provided with an opening on the side and top surface of the right-angled side, such as...

The right-angled sides of the pressure plate 3 and the extended pressure plate 4 are set on the same straight line. The pressure plate 3 and the extended pressure plate 4 are closely attached to the reverse retaining template to avoid gaps caused by the thickness of the plate, which would prevent them from being tightly attached to the template. The bottom surface of the extended pressure plate 4 can strengthen the strength of the extended pressure plate 4 to a certain extent and prevent the two side plates of the extended pressure plate 4 from tilting outward.

[0044] Based on the above implementation method, both the width adjustment pin 6 and the height adjustment pin 11 are wedge-shaped. After insertion, the wedge-shaped structure automatically locks itself by friction of the inclined surface, without the need for additional tightening, such as tightening bolts, which shortens the operation time and improves work efficiency. By adjusting the insertion depth of the wedge-shaped pin, continuous and precise adjustment can be achieved to adapt to slight differences in the thickness or height of the countersunk edge.

[0045] Based on the above implementation method, both the width adjustment pin 6 and the height adjustment pin 11 are provided with auxiliary holes 13 for installing ropes, which can prevent the wedge pin from being lost. When disassembling, the wedge pin can be retrieved by simply pulling the rope, avoiding falling from the gap at a high place and reducing search time.

[0046] Based on the above embodiment, the supporting component includes a reinforcing rod 12, one end of which is hinged to the pressure plate 1, and the other end is adjustablely connected to a pre-installed component on the roof. The supporting component can be adjusted at any angle to adapt to different roof slopes and changes in the position of the curb.

A number of locking teeth 8-1 that cooperate with the inverted L-shaped component 9 are provided on one side of the strip hole 8.

[0048] Example 2, as a preferred embodiment, differs from Example 1 in that it includes a pressure plate 1 located inside the inverted sill, a pressure plate 2 at the top of the inverted sill, and a pressure plate 3 located outside the inverted sill.

The inner wall of the sleeve 5 is in contact with the outer wall of the pressure plate 1. Both the sleeve 5 and the pressure plate 1 are provided with a number of width adjustment grooves 7 and are positioned by width adjustment pins 6. The sleeve 5 drives the pressure plate 1 to move on the pressure plate 2, so as to adjust the distance between the pressure plate 1 and the pressure plate 3 according to the thickness of the guide wall countersill.

[0050] Based on the above implementation method, the extended pressure plate 4 is hollow, the inner wall of the extended pressure plate 4 is fitted with the outer wall of the pressure plate 3, the extended pressure plate 4 is sleeved on the outside of the pressure plate 3 and moves up and down, both the extended pressure plate 4 and the pressure plate 3 are provided with a number of height adjustment grooves 10 and are positioned by height adjustment pins 11, the distance between the pressure plate 3 and the extended pressure plate 4 can be adjusted according to the length and height of the template, and the fit with the guide wall reverse slope template is improved.

[0052] Based on the above embodiment, the extended pressure plate 4 is provided with an opening on the side and top surface of the right-angled side, such as... Figure 3 As shown, the extended pressure plate 4 is fitted outside the pressure plate 3. The right-angled sides of the pressure plate 3 and the extended pressure plate 4 are set on the same straight line. The pressure plate 3 and the extended pressure plate 4 are closely attached to the reverse retaining template to avoid gaps caused by the thickness of the plate, which would prevent them from being tightly attached to the template. The bottom surface of the extended pressure plate 4 can strengthen the strength of the extended pressure plate 4 to a certain extent and prevent the two side plates of the extended pressure plate 4 from tilting outward.

[0053] Based on the above implementation method, both the width adjustment pin 6 and the height adjustment pin 11 are wedge-shaped. After insertion, the wedge-shaped structure automatically locks itself by friction of the inclined surface, without the need for additional tightening, such as tightening bolts, which shortens the operation time and improves work efficiency. By adjusting the insertion depth of the wedge-shaped pin, continuous and precise adjustment can be achieved to adapt to slight differences in the thickness or height of the countersunk edge.

[0054] Based on the above implementation method, both the width adjustment pin 6 and the height adjustment pin 11 are provided with auxiliary holes 13 for installing ropes, which can prevent the wedge pin from being lost. When disassembling, the wedge pin can be retrieved by simply pulling the rope, avoiding falling from the gap at a high place and reducing search time.
