Description

Technical Field

[0001] This utility model relates to the field of roof construction technology, and more specifically, to a tool for roof construction. Background Technology

[0002] During the construction of the emergency water plant, the installation of the steel roof is one of the key steps. Typically, the steel roof is composed of multiple steel plates spliced ​​together and fixed to a steel frame to ensure structural stability and durability. Because steel is greatly affected by temperature changes and is prone to thermal expansion and contraction in high or low temperature environments, expansion joints are usually reserved between adjacent steel plates to buffer the deformation stress caused by thermal expansion and contraction, preventing the roof structure from warping, cracking, or even being damaged due to uneven stress.

[0003] However, the installation of expansion joints presents certain challenges in actual construction. Firstly, the width of the expansion joints needs precise control to meet design requirements while also taking into account construction errors and changes in material properties. Secondly, the location of the expansion joints needs to be rationally planned to ensure the neatness of the steel plate installation and prevent leakage or structural damage during subsequent use. Furthermore, construction sites are often complex environments, making it difficult for workers to accurately measure and locate expansion joints, especially when installing large-area steel roofs. Manual adjustments may lead to uneven gaps, affecting construction quality and subsequent performance. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for roof construction that can quickly and accurately locate the distance and position of expansion joints, and improve the convenience and accuracy of steel roof installation.

[0005] This utility model is achieved through the following technical solution:

[0006] A roofing construction tool, comprising:

[0007] The base has a sliding groove formed in its bottom wall;

[0008] The base has a pair of locking strips arranged in a cross shape on the bottom wall to divide the bottom wall of the base into four areas. At least one of the locking strips is slidably connected to the sliding groove and configured to extend or retract within the sliding groove and be fixed to the moved position.

[0009] The electromagnets are multiple in number and are respectively embedded in four areas of the bottom wall of the base. The base is provided with switches that control each electromagnet to turn on or off.

[0010] Furthermore, one of the clips is fixedly connected to the bottom wall of the base, and a first screw is threadedly connected to the base. The first screw is threadedly connected to the other clip, and the pair of clips are provided with clearance grooves at their cross intersection.

[0011] Furthermore, a fixing plate is fixedly installed around the base, a hard rubber block is installed on the fixing plate, and a vibration plate is fixedly connected to the hard rubber block.

[0012] Furthermore, the base is provided with limiting members at its four corners, which are used to further limit the relative positions between adjacent steel plates.

[0013] Furthermore, the limiting member includes a connecting rod, one end of which is hinged to a hinge seat on the base. The hinge seat and the connecting rod are rotatably connected via a second screw as a pivot, and can be fixed to the rotated position via the second screw. A third screw is threaded onto the connecting rod, and the third screw is used to insert into the bolt hole of the steel plate.

[0014] Furthermore, the connecting rod includes a first rod body and a second rod body slidably inserted into the first rod body, the third screw threaded through the second rod body, the first rod body hinged to the hinge seat, and a positioning element provided on the first rod body, the positioning element being used to limit the sliding position of the second rod body within the first rod body.

[0015] Furthermore, the positioning element includes a limiting spring, one end of which is fixedly connected to the first rod body, and the other end is movably disposed. The limiting spring has a card that is inserted into the first rod body. The second rod body has multiple slots along its length for the card to be inserted.

[0016] Furthermore, a grip handle is fixedly provided on the base.

[0017] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0018] 1. This utility model utilizes a pair of locking strips arranged in a cross shape to embed into the expansion joints between steel plates, achieving rapid and precise positioning. At least one locking strip can slide along a sliding groove and be fixed in a suitable position, making the tool suitable for both straight expansion joints formed by two adjacent steel plates and cross-shaped expansion joints formed by four adjacent steel plates, meeting different construction needs. Simultaneously, multiple electromagnets are embedded in four areas of the base's bottom wall, and their on / off states are independently controlled by corresponding switches, allowing the tool to firmly adhere to the steel plate surface, further improving positioning stability and ease of construction. This tool not only improves the accuracy of steel roof installation but also effectively reduces manual measurement errors and adjustment time, increasing construction efficiency.

[0019] 2. This utility model achieves vibration treatment of the steel plate edges by fixing plates around the base and mounting rigid rubber blocks on the plates, then fixing a vibration plate to the rubber blocks. The rigid rubber blocks effectively buffer vibration transmission, ensuring that vibration energy is concentrated on the steel plate edges, thereby reducing stress concentration and minimizing subsequent deformation caused by thermal expansion and contraction or external loads. This structure improves the long-term stability of the steel roof, reduces maintenance costs caused by steel plate deformation after construction, and simultaneously improves construction quality and service life.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Example

[0030] The following is for reference Figures 1-6 As shown in the illustration, and further illustrated with specific embodiments, this embodiment provides a roof construction tool that achieves precise positioning and efficient construction through optimized structural design.

[0031] The tool includes a base 1, which is made of a wear-resistant and impact-resistant material, such as engineering plastic or aluminum alloy, to ensure its strength and durability. The top of the base 1 has an integrally formed grip handle 10, the surface of which may be provided with anti-slip texture to enhance grip stability and prevent slippage during construction.

[0032] The bottom wall of the base 1 is provided with a sliding groove 11, the depth direction of which is perpendicular to the bottom wall of the base 1, so that the sliding groove 11 can provide adjustable installation space for the clip 2.

[0033] The base 1 is fitted with a pair of locking strips 2 arranged in a cross shape, allowing them to be embedded in the expansion joint 71 between the steel plates 7 for quick and precise positioning. The locking strips 2 can be made of metal or high-strength plastic to provide good support. At least one locking strip 2 is slidably connected to a sliding groove 11 and can extend or retract vertically along the sliding groove 11, and be fixed in a suitable position. This allows the tool to be used for both straight expansion joints 71 formed by two adjacent steel plates 7 and cross-shaped expansion joints 71 formed by four adjacent steel plates 7, meeting different construction needs. To ensure the locking strips 2 are stably fixed after adjustment, a limiting mechanism, such as a spring pin or a threaded locking device, can be provided on the base 1 to facilitate the adjustment of the locking strip 2's position by construction personnel.

[0034] Multiple electromagnets 3 are embedded in four areas of the bottom wall of the base 1. Each electromagnet 3 has a plate-like structure and is independently embedded. It is independently controlled to open or close via a corresponding switch 31, allowing the tool to be firmly attached to the surface of the steel plate 7, further improving the stability of positioning and the convenience of construction. The electromagnets 3 can be made of a high-permeability alloy to provide stronger adsorption force.

[0035] To facilitate independent control of the electromagnet 3's opening and closing, the base 1 is equipped with multiple control switches 31, each corresponding to one electromagnet 3. Construction personnel can selectively open or close the electromagnet 3 as needed, thereby achieving precise fixing or release of construction tools. The switches 31 can be mechanical buttons or touch-sensitive designs, and to prevent accidental operation, locking devices can be installed on the switches 31. Of course, the corresponding power supply and other structures are installed inside the base 1, which will not be described in detail here.

[0036] In this embodiment, in order to facilitate the adjustment of the position of one of the locking strips 2, one of the locking strips 2 is fixedly connected to the bottom wall of the base 1. The base 1 is threaded with a first screw 22, which is threaded to the other locking strip 2. The pair of locking strips 2 are provided with a relief groove 21 at the cross intersection to ensure that the locking strips 2 do not interfere with each other during the adjustment process.

[0037] Furthermore, a fixing plate 4 is fixedly welded around the base 1, and a rigid rubber block 41 is bolted onto the fixing plate 4. A vibrating plate 42 is fixedly connected to the rigid rubber block 41. A vibration motor or other vibration source can be installed inside the vibrating plate 42. Four switches are also installed on the base 1 to control the independent operation of the four vibrating plates 42, thereby realizing vibration treatment of the edge of the steel plate 7. The setting of the rigid rubber block 41 can effectively buffer the vibration transmission, ensuring that the vibration energy is concentrated on the edge of the steel plate 7, thereby reducing stress concentration and reducing subsequent deformation caused by thermal expansion and contraction or external loads.

[0038] As an optional embodiment, limiting members 5 are installed at the four corners of the base 1. The limiting members 5 are used to further limit the relative position between adjacent steel plates 7. In different implementations, the limiting members 5 can be selected as pull rope connecting pins, which are inserted into the bolt holes 72 of the steel plates 7.

[0039] In this implementation, refer to Figure 2 and Figure 5 As shown, the limiting component 5 includes a connecting rod 51. One end of the connecting rod 51 is hinged to the hinge seat 12 of the base 1. The hinge seat 12 and the connecting rod 51 are rotatably connected by a second screw 52 as a pivot, and can be fixed to the rotated position by the second screw 52 to achieve angle adjustment and stabilization of the connecting rod 51. A third screw 53 is threaded onto the connecting rod 51. The third screw 53 is used to insert into the bolt hole 72 of the steel plate 7 to limit the position of the steel plate 7 and ensure the precise positioning of the steel plate 7 during installation.

[0040] Reference Figure 5 As shown, the connecting rod 51 includes a first rod body 511 and a second rod body 512 slidably inserted into the first rod body 511. The first rod body 511 is hinged to the hinge seat 12 to ensure that the limiting member 5 can be adjusted within a certain angle range. The third screw 53 is threaded through the second rod body 512 and can adjust its extension length to adapt to steel plates 7 of different thicknesses or different positioning and installation requirements. A positioning member 6 is installed on the first rod body 511. The positioning member 6 is used to limit the sliding position of the second rod body 512 within the first rod body 511 to prevent the second rod body 512 from accidentally sliding due to external forces during use.

[0041] Furthermore, the positioning component 6 includes a limiting spring 61, one end of which is fixedly connected to the first rod 511, and the other end is movably disposed. The limiting spring 61 has a clip 611 that penetrates the inner wall of the first rod 511 and engages with multiple slots 5121 provided along the length of the second rod 512 to achieve graded limiting adjustment. By adjusting the position of the second rod 512, the positioning component 5 can be adapted to the positions of threaded holes in steel plates 7 of different specifications, improving the flexibility of use.

[0042] In different embodiments, the positioning element 6 can also be a bolt, pin, or elastic pin to fix the relative distance between the second rod 512 and the first rod 511. For example, bolt fixing can apply preload by tightening the bolt to ensure a stable connection; pin fixing can be achieved by inserting the pin into a preset hole to enable quick adjustment and disassembly; elastic pins can utilize their elastic deformation characteristics to achieve reliable positioning within the limiting groove and prevent loosening.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
