Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] The embodiments of the utility model will be described below in combination with Figures 1 to 5

[0030] The utility model provides a kind of post-cast strip support device, comprising:

[0031] Bottom fixing part 1 is used to be fixedly connected with floor slab;

[0032] At least two intermediate connecting pieces 2, at least two intermediate connecting pieces 2 are connected by fastener disassembly, and the first end of intermediate connecting piece 2 close to bottom fixing part 1 is disassembly connected with bottom fixing part 1;

[0033] Jacking piece 3, the first end of jacking piece 3 is disassembly connected with the second end of intermediate connecting piece 2 close to setting, and the second end of jacking piece 3 is provided with support part, and support part is used to abut template.

[0034] Need to be explained, three kinds of standard parts are used in the selection of intermediate connecting piece 2.The first standard part is 1 meter high standard section, can play the connection and support role of foundation in this post-cast strip support device.The second standard part is 1.25 meter high standard section, so that it can provide more flexible height selection in specific construction scene, meet different post-cast strip support needs.The third standard part is 0.65 meter standard section, and its relatively small size can play an important role in some occasions with more accurate height requirements, and the combination use with other two kinds of standard sections, can further enrich the height adjustment range of support device, provide more stable and reliable support for the construction of post-cast strip.

[0035] ​The rear-pouring strip supporting device provided by the embodiment of the utility model can adjust the number of the intermediate connecting pieces 2 according to the height requirement of the rear-pouring strip, thereby realizing height adjustment of the supporting device, meeting the requirements of different floor heights and rear-pouring strip depths, and improving the versatility of the supporting device; the detachable connection between the components can realize flexible assembly according to actual requirements during installation, thereby adapting to different construction environments and meeting different rear-pouring strip size requirements; for the construction operators, the installation process is more efficient, and the installation time and labor cost are reduced; when the rear-pouring strip supporting device needs to be removed, the detachable connection design makes the removal process easier, does not cause excessive damage to the floor and the formwork, improves the reusability, and saves costs.

[0036] Optionally, the fastener comprises a mounting slot arranged at the connection position of the two adjacent intermediate connecting pieces 2 and a mounting column inserted into the mounting slot.

[0037] It should be noted that in the embodiment, the mounting column is a bolt, and a nut is additionally arranged for fixation. This connection mode is firm and has strong adjustability, and the tightness of the connection can be adjusted according to requirements. Meanwhile, the bolt and the nut are common and easy to obtain and replace. Preferably, the mounting slot is arranged on the lower intermediate connecting piece 2, and the mounting column is arranged on the upper intermediate connecting piece 2. Of course, the arrangement can also be reversed.

[0038] In an optional embodiment, a latch hole can also be arranged on the intermediate connection position, and a latch is selected as the mounting column. This connection mode is simple, fast and convenient, and can realize quick assembly and disassembly.

[0039] In another optional embodiment, a protruding bayonet can also be arranged on the intermediate connecting piece 2, and a corresponding groove is arranged on the other intermediate connecting piece 2. The bayonet is inserted into the groove to realize connection. This connection mode does not need additional fasteners, the connection is relatively tight, and the installation and disassembly are relatively convenient.

[0040] Here, the specific arrangement form of the mounting slot and the mounting column is not limited, and stable connection can be ensured.

[0041] Optionally, the mounting slot and the mounting column are arranged on the outer side wall of the intermediate connecting piece 2.

[0042] It is easy to understand that the matching mode of the installation groove and the installation column provides more accurate positioning. When the installation column is inserted into the installation groove, the movement of the intermediate connecting piece 2 in multiple directions can be limited, ensuring the accuracy and stability of the connection. In contrast, if the installation groove and the installation piece are arranged on the connecting surface, the connection may not be tight enough due to unevenness of the connecting surface or construction errors, and looseness or displacement may easily occur; and the connection mode of the installation groove and the installation column makes the installation process more intuitive and simple. The construction personnel only need to align the installation column with the installation groove and insert it to complete the connection, without the need for complex alignment and adjustment operations. This greatly improves the installation efficiency and reduces the installation time and labor cost. Of course, in the face of some building engineering with small load bearing or low installation precision, the fastener can also be arranged on the connecting surface. The installation groove and the installation column are fixed to the intermediate connecting piece 2 by welding.

[0043] Optionally, the second end of the intermediate connecting piece 2 is provided with a connecting cavity, the connecting cavity is provided with an internal thread, the first end of the shore 3 is provided with an external thread, and the first end of the shore 3 is adapted to be inserted into the connecting cavity to be connected with the intermediate connecting piece 2 in an extension and retraction mode.

[0044] It is easy to understand that the extension and retraction connection of the shore 3 and the intermediate connecting piece 2 is achieved by thread connection, which can achieve very fine height adjustment. Construction personnel can accurately adjust the support height according to actual needs to meet the requirements of different post-cast strip construction, and the thread connection has a certain self-locking property, which can maintain stability after the height is adjusted and will not change due to slight external force, ensuring the reliability of the formwork support.

[0045] In another optional embodiment, a plurality of insertion pin holes perpendicular to the height direction can also be arranged on the second end of the intermediate connecting piece 2 and the first end of the shore 3 respectively, and different height adjustments can be achieved by inserting the insertion pin. This connection mode is simple and reliable, and the cost is relatively low. However, the height adjustment precision of the insertion pin type connection is relatively low, and the insertion pin needs to be inserted and pulled out multiple times during installation, which is relatively cumbersome to operate.

[0046] Optionally, a limiting piece 4 is further included, the limiting piece 4 is sleeved and threadedly connected to the shore 3, and the limiting piece 4 can move along the axial direction of the shore 3.

[0047] It is easy to understand that the limiting piece 4 is threadedly connected to the shore 3 and can be moved to a suitable position along the axial direction according to actual needs, thereby limiting the shore 3. When the height of the shore 3 is adjusted and connected with the intermediate connecting piece 2, the limiting piece 4 can abut against the end of the intermediate connecting piece 2, preventing the shore 3 from accidentally retracting or extending when subjected to external force, thereby ensuring the stability of the entire support device.

[0048] Optionally, the limiting member 4 has two notches formed by inwardly recessing in the axial direction perpendicular to the top support 3, and the two notches are suitable for clamping the two rotating arms 41 of the limiting member 4.

[0049] It should be noted that the two notches provide a special clamping position for the rotating arm 41, so that the operator can adjust the limiting member 4 more conveniently and quickly. By clamping the rotating arm 41 into the notch, the limiting member 4 can be rotated more easily without the need to exert force to directly hold and rotate the limiting member 4, thereby reducing the operation difficulty.

[0050] Optionally, the first end of the intermediate connecting member 2 is provided with an outer protrusion or a receiving cavity, and the side of the bottom fixing member 1 close to the intermediate connecting member 2 is provided with a receiving cavity or an outer protrusion, and the outer protrusion is suitable for being inserted into the receiving cavity.

[0051] It is easy to understand that the cooperation of the outer protrusion and the receiving cavity can achieve quick positioning when installing the intermediate connecting member 2 and the bottom fixing member 1. The operator does not need to spend a lot of time on alignment operation, but only needs to insert the outer protrusion into the receiving cavity to determine the relative position of the two, thereby improving the installation efficiency.

[0052] Optionally, at least one set of locking members is further included, and each set of locking members includes two locking nuts and one locking bolt, the two locking nuts are respectively arranged on the outer circumferential surface of the connection between the intermediate connecting member 2 and the bottom fixing member 1, and the axes of the two locking nuts are in the same straight line, and the locking bolt is suitable for being threadedly connected with the two locking nuts at the same time.

[0053] It should be noted that the combination of the two locking nuts and the locking bolt forms a double locking mechanism, which can enhance the stability of the connection between the intermediate connecting member 2 and the bottom fixing member 1. During the construction process, the support device will bear various pressures and vibrations from the formwork, concrete and the like, and such locking members can effectively prevent the loosening of the connection, thereby ensuring the firmness and reliability of the entire support system.

[0054] It is easy to understand that in the embodiment, the number of locking members is 4 sets, which are arranged around the intermediate connecting member 2 and the bottom fixing member 1. In other embodiments, it can also be arranged as 2 sets, 3 sets or more sets, and here, the specific number is not limited as long as the stable connection is ensured.

[0055] In an optional embodiment, a pin hole can also be arranged at the connection between the intermediate connecting member 2 and the bottom fixing member 1, and a pin is used for connection. The pin has good bearing capacity and shear resistance. Such connection mode is simple and reliable, and is convenient for installation and disassembly, and is suitable for some occasions with low connection strength requirements.

[0056] In another optional embodiment, a special bayonet structure can also be designed at the connection between the intermediate connecting piece 2 and the bottom fixing piece 1, so that the intermediate connecting piece 2 and the bottom fixing piece 1 can be connected to each other through the bayonet. The bayonet connection can realize quick installation and disassembly, and has a certain self-locking function, which can prevent loosening at the connection to a certain extent. However, the carrying capacity of the bayonet connection is relatively weak, and is suitable for some light support devices.

[0057] Optionally, the bottom fixing piece 1 comprises at least three bases arranged on the same horizontal plane, and any two bases are fixedly connected to each other, and the number of the top supporting pieces 3 is at least three, which are respectively inserted into the intermediate connecting piece 2.

[0058] It is easy to understand that the at least three bases arranged on the same horizontal plane can provide a more stable foundation for the entire support device. When supporting the formwork and bearing the weight of concrete, etc., it is not easy to incline or shake, ensuring the safety and stability of the construction process; the plurality of top supporting pieces 3 are respectively connected to the intermediate connecting piece 2, which also increases the uniformity and reliability of the support. Compared with only one or two supporting points, the at least three top supporting pieces 3 can better disperse the pressure and reduce the situation of excessive local stress, thereby improving the carrying capacity of the entire support device.

[0059] It should be noted that in the embodiment, the number of bases and top supporting pieces 3 is set to four, and in other embodiments, the number of bases and top supporting pieces 3 can also be selected according to the actual load condition. Here, the number and specific setting form are not limited.

[0060] Optionally, a plurality of through holes are arranged around the base, and the post-cast strip support device further comprises a plurality of fixing bolts, which pass through the through holes to fixedly connect the base and the floor.

[0061] It is easy to understand that the combination of a plurality of through holes and fixing bolts can form a multi-point fixation between the base and the floor, greatly enhancing the firmness of the connection. During the construction process, the support device needs to bear the huge pressure from the formwork, concrete, etc., and this multi-point fixation method can ensure that the base will not easily loosen or shift, providing a stable foundation for the entire support system.

[0062] In the embodiment, an expansion bolt is selected as the fixing bolt. The expansion bolt is a common fixing connecting piece, which is inserted into the hole drilled in the floor, and then the bolt is tightened to expand the expansion tube at the tail of the bolt, thereby forming a tight connection with the floor.

[0063] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
