Description

A device and installation method for an exposed lightning protection strip on a parapet Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a device for exposing a lightning protection strip on a parapet and an installation method thereof. Background Art

[0002] The design of parapet walls on building roofs is becoming increasingly diverse, with some projects already using marble slabs as the decorative surface. Beneath the decorative surface lies the curtain wall framework and thermal insulation layer. The marble is 20 to 40 mm thick, which doesn't meet the 100 mm buried depth requirement for lightning protection strip supports as specified in the drawings.

[0003] Some construction companies use concealed lightning protection strips, which are laid under the insulation layer and marble, significantly reducing the lightning protection performance. Some construction companies drill holes directly into the marble slabs to bury the lightning protection strip brackets. This method not only fails to meet the bracket burial depth requirements, but also easily causes water leakage at the drilled holes.

[0004] Some construction companies use marble slabs to hold down flat steel on marble parapets, using the flat steel as a support for laying lightning protection strips. However, the buried depth of the support still does not meet the design requirement of 100mm, which cannot meet the requirements of the design drawings. In addition, the marble slabs are glued to the marble slabs of the parapet, and the adhesive is prone to aging, causing the lightning protection strip support to loosen and shift.

[0005] Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a device for applying an exposed lightning protection strip on a parapet and an installation method thereof.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A parapet-mounted lightning protection strip device includes a rectangular slot formed on one side of a top portion of a marble slab, a connecting slot extending through one end of the top portion of the rectangular slot, and a galvanized flat steel bar inserted into the inner wall of the rectangular slot. A concrete test block is placed on the top portion of the connecting slot, and a through hole is formed through the center of the concrete test block. Positioning slots are formed around the concrete test block, and a rectangular positioning frame is fixed to the bottom of the concrete test block. A symmetrically distributed L-shaped hanging plate is welded to an outer wall of one side of the rectangular positioning frame, and a fixing plate is welded to an outer wall of the other side of the rectangular positioning frame.

[0009] An L-shaped galvanized round steel bracket is inserted into the inner wall of the through hole, and the bottom of the L-shaped galvanized round steel bracket is welded to the top of the galvanized flat steel. A lower arc plate is welded to the outer wall of the end of the L-shaped galvanized round steel bracket, and a round steel lightning strip is inserted into the inner wall of the lower arc plate. An upper arc plate is hinged on one side of the lower arc plate, and one side of the lower arc plate and the upper arc plate are fixed by fixing bolts. A grounding ring is welded to the outer wall of one side of the bottom of the round steel lightning strip.

[0010] Preferably, the through hole is located directly above the communicating groove, and the inner wall diameter of the communicating groove is matched with the inner wall diameter of the through hole.

[0011] Through the above solution, the size of the connecting groove is the same as the size of the through hole, which can ensure that the L-shaped galvanized round steel bracket can be smoothly inserted and fixed.

[0012] Preferably, a rectangular sealing groove is provided on the top of the marble slab below the concrete test block, and a rectangular sealing gasket is provided on the inner wall of the rectangular sealing groove. Waterproof glue is also provided around the rectangular sealing gasket.

[0013] Through the above solution, by arranging a rectangular sealing pad and waterproof glue under the concrete test block, the sealing performance can be doubled to avoid water seepage at the opening.

[0014] Preferably, elastic clamping plates are welded around the top of the rectangular positioning frame, and the elastic clamping plates are tightly fitted with the positioning slots.

[0015] Through the above solution, the elastic clamping plates clamped around the concrete test block can further improve the stability of the concrete test block.

[0016] Preferably, an adjusting screw is rotatably provided on the outer wall of one side of the top of the fixing plate, and a positioning clamp is screwed on the outer wall of the adjusting screw. Limiting holes are opened on the outer walls of both sides of the positioning clamp, and the inner walls of the limiting holes are slidably inserted with limiting rods.

[0017] Through the above solution, the positioning splint is clamped on the top of the marble slab, which can improve the overall stability of the lightning protection strip and avoid shaking over time.

[0018] Preferably, a fixing groove is opened on one side outer wall of the L-shaped galvanized round steel bracket, and a reinforcing support rod is inserted and installed on the inner wall of the fixing groove.

[0019] Through the above solution, the right-angle turning part of the L-shaped galvanized round steel bracket is subjected to greater force, so a reinforcing strut is set up to improve the overall strength.

[0020] Preferably, the outer walls between adjacent round steel lightning protection strips are sleeved with a sleeve, and the outer wall of the bottom of the sleeve is welded with a C-shaped lightning protection strip.

[0021] Through the above scheme, the segmented round steel lightning strip can be easily transported and installed. The right-angle turning part of the wall can be connected with the bent C-shaped lightning strip, thereby avoiding the overall bending of the round steel lightning strip.

[0022] Preferably, a first clamping block is clamped and installed on the top outer wall of the L-shaped galvanized round steel bracket, and a symmetrically distributed second clamping block is clamped and installed on the top outer wall of the round steel lightning strip. A fixed diagonal rod is welded between the first clamping block and the second clamping block, and an arc-shaped metal rod is welded on the top of the second clamping block, and a lightning rod is welded at the center of the top of the arc-shaped metal rod.

[0023] Through the above scheme, the triangular clamping arrangement is adopted to ensure the overall stability, and a lightning rod is set on the top of the round steel lightning strip to further improve the lightning protection effect.

[0024] A method for installing an exposed lightning protection strip on a parapet, comprising the following steps:

[0025] S1: First, a rectangular slot is opened on one side of the top of the marble slab, and a connecting slot is opened on the top of the rectangular slot. The rectangular sealing gasket is placed inside the rectangular sealing slot, and the concrete test block is inserted into the bottom outer wall of the L-shaped galvanized round steel bracket;

[0026] S2: Further, the galvanized flat steel is inserted into the rectangular slot, and the bottom of the L-shaped galvanized round steel bracket is welded to the top of the galvanized flat steel. After completion, waterproof glue is applied to the outer wall of the bottom of the concrete test block, and a rectangular positioning frame is placed on the outside of the concrete test block. The concrete test block is pressed and bonded to the top of the marble slab;

[0027] S3: After the concrete test block is bonded, the elastic clamping plate is clamped into the positioning slot to fix the concrete test block. The L-shaped hanging plate is hung on one end of the top of the marble slab, and the other end is adjusted with a welded adjustment screw, and the positioning clamp is used to clamp and fix the concrete test block.

[0028] S4: After fixing, insert the reinforcing support rod into the fixing groove to strengthen the support of the L-shaped galvanized round steel bracket, and connect the C-shaped lightning strips between adjacent round steel lightning strips. Connect a bent C-shaped lightning strip at the right-angle turn of the wall to make a stable connection, and clamp the arc-shaped metal rod on the top of the round steel lightning strip, and use the lightning rod for double lightning protection.

[0029] The beneficial effects of the present invention are:

[0030] 1. The exposed lightning protection strip device of this design opens a rectangular slot at the center of the top of the marble slab and sets a rectangular sealing gasket and waterproof glue around the joint at the top of the rectangular slot. Therefore, the lightning protection strip after installation can not destroy the overall waterproofness of the marble slab, but also improve the stability and standardization after installation;

[0031] 2. During the installation process of the open-laid lightning protection strip device of this design, the round steel lightning protection strip is installed in sections, which can improve the convenience of transportation and further improve the speed of installation. A bendable C-shaped lightning protection strip is connected at the right-angle bend of the connection, which not only does not affect the normal lightning protection treatment, but also improves the overall aesthetics and stability.

[0032] 3. The exposed lightning strip device of this design uses round steel lightning strips for rapid lightning protection during the lightning protection process, and a lightning rod is installed on the top of the round steel lightning strip to further improve the lightning protection effect. The triangular support structure at the bottom has sufficient stability to prevent the lightning rod from tilting after being fixed. BRIEF DESCRIPTION OF THE DRAWINGS
