Description

Technical Field

[0001] The utility model relates to the technical field of building template construction equipment, and more specifically, to a welding-free double-tube back rib. Background Art

[0002] In recent years, with the vigorous development of the construction industry, aluminum formwork has been used more and more widely instead of traditional formwork in construction projects. In the construction industry, when pouring concrete, building formwork is needed to form the building. The building formwork needs to be supported by a frame structure. The back rib is placed on the back of the building formwork to reinforce and support the construction project formwork. The back rib plays a vital role in ensuring the strength of the aluminum formwork and the concrete pouring effect.

[0003] At present, the vertical back ribs commonly used in the construction field are single-tube back ribs and double-tube back ribs. The double-tube back ribs provide greater support and higher strength, so they are more commonly used. The double-tube back ribs usually require two straight square tubes to be welded together through a small square tube, and then a perforated gasket is welded on the back of the square tube. After long-term use, the back ribs will become unsolderable. The back ribs cannot be used after desoldering, which reduces the reinforcement effect of the back ribs. Re-welding will seriously affect the progress of on-site construction. Utility Model Content

[0004] The purpose of the utility model is to overcome the problem that the double-tube back ribs in the prior art need to be welded, and to provide a welding-free double-tube back rib, so that the double-tube back ribs do not need to be welded, thereby increasing their service life.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A welding-free double-tube back rib is provided, comprising a first square tube, a second square tube parallel to the first square tube, and a connecting piece, wherein the connecting piece comprises a first baffle, a second baffle, a connecting plate, a separator, and a fastener installed on the connecting piece, wherein the first baffle and the second baffle are respectively fixed on both sides of the connecting plate, the first baffle is parallel to the second baffle, the separator is located between the first baffle and the second baffle, the first square tube is located between the first baffle and the separator, and the second square tube is located between the second baffle and the separator, and the fastener is used to fix the first square tube, the second square tube, and the separator to the connecting piece.

[0007] The utility model provides a welding-free double-tube back rib, wherein the first baffle and the second baffle are fixedly connected with the connecting plate, the separator is located between the first baffle and the second baffle, and two mounting grooves are formed between the separator and the first baffle and the second baffle respectively. The first square tube and the second square tube are fixedly installed in the two mounting grooves respectively, and the separator separates the first square tube and the second square tube by a certain distance, so that the L-shaped screw can pass through the gap between the first square tube and the second square tube and fix the double-tube back rib on the transverse reinforcement back rib. There is no need to weld the first square tube and the second square tube through a small square tube, which avoids the risk of desoldering between the first square tube and the second tube, and improves the service life of the double-tube back rib. The fastener locks the first square tube, the second square tube and the separator on the connecting piece, so that the overall fixing effect of the double-tube back rib is better and the supporting strength is greater.

[0008] Furthermore, the separator is a partition plate, which is perpendicular to the connecting plate, and one end of the separator plate abuts the connecting plate. The separator plate and the connecting plate are in abutment state, so the separator plate can be removed. The separator plate can be selected with an appropriate thickness according to the size of the L-shaped screw or the size of the square tube to improve applicability.

[0009] Furthermore, the separator is also provided with a raised portion that engages with the transverse reinforcement back ribs to limit back rib displacement. The vertical back ribs need to be installed a certain distance from the ground during the leveling and reinforcement process. The raised portion can engage with the transverse reinforcement back ribs to support the double-tube back ribs at a certain position on the transverse reinforcement back ribs, preventing the double-tube back ribs from sliding under the weight, making it easier for operators to reinforce the double-tube back ribs and providing greater convenience.

[0010] Furthermore, the first baffle, the second baffle, the first square tube, the second square tube, and the separator are all provided with corresponding through-holes, through which the fasteners pass. The fasteners sequentially pass through the through-holes of the first baffle, the first square tube, the separator, the second square tube, and the second baffle, thereby preventing relative movement between the components. This results in a better overall fixation effect and greater support strength for the back ribs. The through-hole design also facilitates installation, allowing multiple components to be connected into a whole in just one go, providing greater convenience.

[0011] Furthermore, the fasteners include bolts and nuts. The bolts sequentially pass through through-holes in the first baffle, the first square tube, the separator, the second square tube, and the second baffle, and are threadedly connected to the nuts. The bolt heads and nuts respectively abut against two sides of the connectors. The screws sequentially pass through the through-holes and are threadedly connected to the nuts. By turning the nuts, the tightness between the components can be adjusted, thereby achieving disassembly or assembly of the double-tube back rib. The threaded connection facilitates assembly and disassembly and provides a good fixing effect.

[0012] Furthermore, the connecting member also includes a fixing member fixedly mounted on the connecting plate, the fixing member is used to connect to an external fixture, and the fixing member can be connected to other reinforcement devices such as diagonal braces, so that the overall fixing effect of the double-tube back rib is better and the supporting strength is greater.

[0013] Furthermore, the fixing member includes two fixing plates installed in parallel and perpendicular to the connecting plate, and the two fixing plates are provided with corresponding through holes, which can facilitate the passage of connecting members such as bolts and nuts.

[0014] Furthermore, the connector is integrally formed, which makes the processing and production of the connector convenient and quick, reduces the process flow, and the connection strength between the components is high and will not break easily.

[0015] Furthermore, the material of the separator is rubber, so that the separator has high strength, can withstand large pressure without breaking, and has high corrosion resistance and can be used for a long time.

[0016] Furthermore, the connecting piece is made of any one of steel, aluminum or plastic.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. A mounting groove is formed between the separator and the first baffle and the second baffle. The first square tube and the second square tube are fixedly installed in the two mounting grooves respectively. There is no need to weld the first square tube and the second square tube through a small square tube, which avoids the risk of desoldering between the first square tube and the second square tube and improves the service life of the back rib.

[0019] 2. The setting of fasteners and fixing parts makes the overall fixing effect of the back rib better and the supporting strength greater;

[0020] 3. The raised portion can be connected to the transverse reinforcement back rib so that the double-tube back rib is supported at a certain position on the transverse reinforcement back rib, so that the double-tube back rib can not slide down due to the weight, which is convenient for operators to install quickly and more convenient.

[0030] Example 1

[0031] This embodiment is a first embodiment of a double-tube back rib without welding. Figure 1-6As shown, it includes a first square tube 100, a second square tube 200 parallel to the first square tube 100, and a connecting member 300. The connecting member 300 includes a rectangular first baffle 310, a rectangular second baffle 320, a rectangular connecting plate 330, a separator 340, and a fastener 350 installed on the connecting member 300. The first baffle 310 and the second baffle 320 are respectively fixed on both sides of the connecting plate 330. The first baffle 310 is parallel to the second baffle 320. In this embodiment, the separator 340 is a separator 341. The partition 340 is located between the first baffle 310 and the second baffle 320, the partition 341 is perpendicular to the connecting plate 330, the partition 341 is parallel to the first baffle 310, one end of the partition 341 is in contact with the connecting plate 330, the first square tube 100 is located between the first baffle 310 and the partition 341, the second square tube 200 is located between the second baffle 320 and the partition 341, and the fastener 350 is used to fix the first square tube 100, the second square tube 200 and the partition 341 on the connecting member 300.

[0032] The working principle of the welding-free double-tube back rib in this embodiment is as follows:

[0033] The first baffle 310 and the second baffle 320 are fixedly connected to both sides of the connecting plate 330, and the partition plate 341 is located between the first baffle 310 and the second baffle 320. The partition plate 341 forms two mounting grooves with the first baffle 310 and the second baffle 320 respectively. The first square tube 100 and the second square tube 200 are fixedly installed in the two mounting grooves respectively. The partition plate 341 separates the first square tube 100 and the second square tube 200 by a certain distance. The L-shaped screw 500 passes through the fixing hole on the transverse reinforcement back rib 400 and passes through the gap between the first square tube 100 and the second square tube 200, and then fixes the double-tube back rib to the transverse reinforcement back rib 400 by tightening the fixing nut. There is no need to weld the first square tube 100 and the second square tube 200 through a small square tube to avoid welding between the first square tube 100 and the second square tube 200. The risk of desoldering is reduced, and the service life of the double-tube back ribs is improved. The partition plate 341 and the connecting plate 330 are in abutment with each other, so the partition plate 341 can be removed. The partition plate 341 of appropriate thickness can be selected according to the size of the L-shaped screw 500 used or the size of the square tube, and the applicability is better. Since the vertical back ribs need to be installed at a certain distance from the ground during the leveling and reinforcement process, the protrusion 342 can be snapped into the transverse reinforcement back ribs 400 so that the double-tube back ribs are supported at a certain position on the transverse reinforcement back ribs 400, so that the double-tube back ribs are not affected by the weight and do not slide, which is convenient for operators to reinforce the double-tube back ribs, and the convenience is better. The fastener 350 locks the first square tube 100, the second square tube 200 and the partition plate 341 on the connecting piece 300, so that the overall fixing effect of the double-tube back ribs is better and the supporting strength is greater.

[0034] The beneficial effects of this embodiment are as follows:

[0035] The first square tube 100 and the second square tube 200 do not need to be welded through a small square tube, which avoids the risk of desoldering between the first square tube 100 and the second square tube 200 and improves the service life of the double-tube back rib. The raised portion 342 is engaged with the transverse reinforcement back rib 400, so that the double-tube back rib will not slip due to weight during installation. It can also be easily positioned to assist operators in quick installation, which is more convenient. The partition plate 341 and the connecting plate 330 are in abutment state, so the partition plate 341 can be removed. The partition plate 341 of appropriate thickness can be selected according to the size of the L-shaped screw 500 used or the size of the square tube, which has better applicability. The fastener 350 locks the first square tube 100, the second square tube 200 and the partition plate 341 on the connecting member 300, so that the overall fixing effect of the double-tube back rib is better and the supporting strength is greater.

[0036] In addition, the connecting piece 300 can also connect a larger number of square tubes, such as a three-tube back rib. In this embodiment, it includes a connecting piece 300, three square tubes and two partition plates 341. The two partition plates 341 are located between the first baffle 310 and the second baffle 320. The two partition plates 341 respectively form two installation grooves with the first baffle 310 and the second baffle 320. A installation groove is formed between the two partition plates 341. The three square tubes are respectively fixed in the three installation grooves. In actual engineering, the number of square tubes can be adjusted according to the required strength.

[0037] Here, another connection method between the partition plate 341 and the connecting plate 330 is provided. In this embodiment, the partition plate 341 and the connecting plate 330 are connected by screws. The partition plate 341 and the connecting plate 330 can be assembled or disassembled by turning the screws, which increases the fixing strength and allows for assembly and disassembly, and has better applicability.

[0038] Example 2

[0039] This embodiment is a second embodiment of a double-tube back rib without welding. This embodiment is similar to the first embodiment, except that Figure 2 As shown, the fastener 350 includes a bolt 351 and a nut. The first baffle 310, the second baffle 320, the first square tube 100, the second square tube 200, and the separator 340 are all provided with corresponding through-holes. The bolt 351 passes through the through-hole and is threadedly connected to the nut. The screw head of the bolt 351 and the nut respectively abut against the two sides of the connector 300. The corresponding through-holes refer to the through-holes arranged equidistantly on the first square tube 100 and the second square tube 200. The first baffle 310, the second baffle 320, and the separator 340 are also provided with through-holes that can be coaxial with any two adjacent through-holes on the first square tube 100.

[0040] The working principle of this embodiment is as follows: Bolts 351 are sequentially passed through the through-holes of the first baffle 310, the first square tube 100, the separator 340, the second square tube 200, and the second baffle 320, and are threadedly connected to nuts. By turning the nuts, the tightness between the components can be adjusted to prevent relative movement of the components, thereby enabling the disassembly or assembly of the double-tube back rib. The threaded connection is easy to disassemble and assemble, and has a good fixing effect. The through-hole design also makes installation more convenient, allowing multiple components to be connected into a whole in a single operation, which is more convenient.

[0041] Another embodiment of the fastener 350 is provided herein. Different from the above embodiment, the fastener 350 is a positioning pin, which passes through the through holes on the first baffle 310, the first square tube 100, the partition 340, the second square tube 200 and the second baffle 320 in sequence, thereby realizing disassembly or assembly between the components.

[0042] Example 3

[0043] This embodiment is a third embodiment of a double-tube back rib without welding. This embodiment is similar to the first and second embodiments, except that Figure 3-6 As shown, the connecting member 300 also includes a fixing member 360 fixedly installed on the connecting plate 330. In this embodiment, the fixing member 360 is two fixing plates 361 installed in parallel and perpendicular to the connecting plate 330. The two fixing plates 361 are provided with symmetrical through holes. The fixing member 360 is used to connect to an external fixed object.

[0044] The working principle of this embodiment is as follows: Bolts 351 pass through the through holes of the two fixing plates 361 and are locked together with nuts, thereby fixing the diagonal brace 600 to the fixing plates 361. This improves the overall fixing effect and supports greater strength of the double-tube back rib. Alternatively, pins or rivets can be inserted through the through holes to achieve fixation.

[0045] Another implementation of the fixing member 360 is provided here. Different from the above embodiment, the fixing member 360 is a hanging ring, and a hook is provided at one end of the diagonal support 600. The hook passes through the hanging ring to achieve the connection and fixation of the diagonal support 600 and the fixing member 360.

[0046] Example 4

[0047] This embodiment is a fourth embodiment of a double-tube back rib without welding. This embodiment is similar to the first, second and third embodiments, except that Figure 3 As shown, the connecting member 300 is integrally formed, the material of the partition 340 is rubber, and the material of the connecting member 300 is steel. In addition, aluminum, plastic, etc. can also be used.

[0048] The working principle of this embodiment is as follows:

[0049] The connector 300 is integrally formed, which makes the processing and production of the connector 300 convenient and fast, reduces the process flow, and the connection strength between the components is high and will not break easily. The partition plate 341 is made of rubber, which makes the partition plate 341 have high strength and can withstand greater pressure without breaking. It also has high corrosion resistance and can be used for a long time.
