Description

Technical Field

[0001] The invention relates to the technical field of industrial building construction, and in particular to a floor expansion joint bracket. Background Art

[0002] Large factories often use concrete industrial floors. In order to prevent the cracking, settlement, shrinkage and deformation of the floor concrete, it is necessary to install expansion joint products in the industrial floor. The expansion joint products can refer to the utility model CN218970522U disclosed by the applicant.

[0003] Existing industrial floor construction uses expansion joint products to divide the floor. Specifically, the expansion joint products are placed on the floor foundation cushion layer marked with grid lines, and concrete is poured in the floor base. After the construction is completed, holes are drilled and positioning steel bars are buried. After that, the concrete shrinks to pull the expansion joint products apart to form expansion joints, which are then sealed with sealant.

[0004] In order to ensure the accuracy of the installation position of the expansion joint products during the construction process, expansion joint brackets are usually used to control the installation position (elevation position) of the expansion joint products.

[0005] At present, the expansion joint products are long and heavy, and at least two brackets are required to adjust the height of the expansion joint products. The existing brackets include a stand with an adjustment screw, which guides the ball nut to move up and down, wherein a sliding sleeve sleeved on the stand is fixed to the ball nut by a bolt. When in use, the sliding sleeve is fixed to the expansion joint product, and at this time, the weight of the expansion joint product and the pressure of the poured concrete are resisted by the bolts, the ball nut and the adjustment screw.

[0006] The defect of the existing expansion joint bracket is that the ball nut is inside the frame and the sliding sleeve is outside the frame. Therefore, there is a distance between the sliding sleeve and the ball nut, which makes the bolt part exposed. The pressure on the sliding sleeve is transmitted to the ball nut only through the bolt. For the exposed bolt part, the pressure it can withstand is limited, and it is difficult to adapt to heavier expansion joint products and heavier concrete pouring construction. Summary of the invention

[0007] The object of the present invention is to improve the problem in the prior art that the exposed portion of the bolt in the bracket can withstand limited pressure.

[0008] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a floor expansion joint bracket, comprising: a vertical frame equipped with an adjusting screw, a ball nut arranged in the vertical frame cooperates with the adjusting screw thread, and the rotation of the adjusting screw guides the ball nut to move up and down in the vertical frame.

[0009] The side end of the sliding sleeve sleeved on the vertical frame is provided with an elevation component.

[0010] The floor expansion joint bracket also has a polygonal reinforcement shaft, which is telescopically connected to the ball nut and is exposed in the direction of the opening groove opened by the vertical frame.

[0011] The reinforcing shaft is provided with a threaded hole, and an adjusting bolt disposed on the sliding sleeve is connected to the threaded hole. Tightening of the adjusting bolt guides the reinforcing shaft to telescope and slide, so that the reinforcing shaft can be embedded in the recess of the sliding sleeve, becoming a supporting structure for the sliding sleeve and the ball nut.

[0012] The beneficial effects of the present invention are:

[0013] When the ball nut and the sliding sleeve are positioned, the adjusting bolt on the sliding sleeve is threadedly connected to the reinforcing shaft on the side of the ball nut. When the head end of the adjusting bolt is screwed to the outer surface of the sliding sleeve, the adjusting bolt is no longer screwed into the reinforcing shaft when the adjusting bolt is continuously screwed. Instead, the adjusting bolt guides the reinforcing shaft to approach the sliding sleeve and is embedded in the recess of the sliding sleeve, so that the reinforcing shaft becomes a supporting structure for the sliding sleeve and the ball nut, thereby improving the supporting strength of the floor expansion joint bracket and enabling the floor expansion joint bracket to more easily adapt to heavier expansion joint products and thicker concrete pouring construction.

[0014] By rotating the adjusting bolt, the reinforcing shaft can be easily moved to become the supporting structure of the sliding sleeve and the ball nut. Compared with the larger adjusting bolts required to achieve the same supporting strength, less material is used. In addition, the installation of larger adjusting bolts will be more difficult and will generate greater clamping force, which is easy to compress the thinner sliding sleeve and deform it.

[0015] Furthermore, in an embodiment of the present invention, the reinforcement shaft is a triangular, quadrilateral, pentagonal or hexagonal structure.

[0016] Furthermore, in an embodiment of the present invention, the reinforcement shaft is made of carbon steel material.

[0017] Furthermore, in an embodiment of the present invention, a vertical platform is provided on the bottom of the vertical frame, and a vertical bolt is configured on the vertical platform. By turning the vertical bolt on the vertical platform, the extension length of the vertical bolt can be controlled. Since the vertical bolt is against the lower side of the expansion joint product, the verticality of the expansion joint product can be adjusted by controlling the extension length of the vertical bolt, thereby ensuring the quality of the final construction.

[0018] Furthermore, in an embodiment of the present invention, a positioning platform is inserted into the end surface of the ball nut exposed to the open groove, and a positioning block is welded on the inner side of the sliding sleeve, and the positioning block is embedded in the notch of the positioning platform.

[0019] The sliding sleeve is arranged on the stand, and the positioning block and the positioning table are engaged, which can improve the supporting strength of the ball nut and the sliding sleeve on the one hand, and position the ball nut and the sliding sleeve on the other hand, so as to better install the adjusting bolt.

[0020] Furthermore, in an embodiment of the present invention, the positioning platform is perpendicular to the ball nut, and the positioning block is perpendicular to the sliding sleeve.

[0021] Furthermore, in an embodiment of the present invention, the upper end of the adjusting screw rod is exposed above the stand, and a nut is installed on the exposed portion of the upper end of the adjusting screw rod.

[0022] Furthermore, in an embodiment of the present invention, the elevation component is provided with an elevation support rod, and the elevation support rod can move laterally within the sleeve of the elevation component.

[0023] Furthermore, in an embodiment of the present invention, a support rod is provided at the bottom of the sleeve of the elevation component, and the support rod is connected to the stand.

[0024] Furthermore, in an embodiment of the present invention, the elevation support rod located in the sleeve is provided with a tapered hole connected to the tapered hole on the sleeve side, and the tapered locking shaft equipped with the elevation component is inserted into the tapered hole of the elevation support rod and the tapered hole of the sleeve.

[0025] The lock shaft is equipped with a pressure plate pressed on the sleeve, and a baffle is fixed on the side end of the sleeve, and the baffle abuts against the pressure plate to limit the movement of the lock shaft.

[0026] The method of inserting the locking shaft into the tapered hole of the high support rod and the tapered hole of the sleeve not only speeds up the connection, but also the coordination of the tapered structure enables a tighter contact.

[0027] The pressing plate that moves horizontally with the lock shaft only needs to be rotated into the groove between the baffle plate and the pipe sleeve to limit the movement of the lock shaft, so as to complete a quick fixed installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious. For those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments may be used in combination with each other.

[0039] Embodiment 1:

[0040] It should be noted that the drawings in the specification are the contents of the specification. The structural shapes, connection relationships, matching relationships, and positional relationships that can be obtained without any doubt in the drawings in the specification should be understood as the contents of the specification.

[0041] A floor expansion joint bracket, such as Figure 1-Figure 4 As shown, it comprises: a stand 10 equipped with an adjusting screw 12, a ball nut 20 arranged in the stand 10 and threadedly matched with the adjusting screw 12, that is, the ball nut 20 is threadedly connected to the adjusting screw 12, and the rotation of the adjusting screw 12 guides the ball nut 20 to move up and down in the stand 10.

[0042] like Figure 2 As shown, a height elevation component 40 is disposed on the side end of the sliding sleeve 30 sleeved on the stand 10 .

[0043] like Figure 3 , Figure 4 As shown, the floor expansion joint bracket also has a polygonal reinforcement shaft 21, which is telescopically connected to the ball nut 20, and the reinforcement shaft 21 is exposed in the direction of the opening slot 11 opened by the stand 10.

[0044] like Figure 4 As shown, the reinforcing shaft 21 is provided with a threaded hole, and the adjusting bolt 31 disposed on the sliding sleeve 30 is connected to the threaded hole. The turning of the adjusting bolt 31 guides the reinforcing shaft 21 to telescope and slide, so that the reinforcing shaft 21 can be embedded in the recess of the sliding sleeve 30, becoming a supporting structure for the sliding sleeve 30 and the ball nut 20.

[0045] The advantage of the present invention is that when positioning the ball nut 20 and the sliding sleeve 30, the adjusting bolt 31 on the sliding sleeve 30 is threadedly connected with the reinforcing shaft 21 on the side of the ball nut 20. When the head end of the adjusting bolt 31 is screwed to the outer surface of the sliding sleeve 30, when the adjusting bolt 31 is continued to be screwed, the adjusting bolt 31 is no longer screwed into the reinforcing shaft 21, and the adjusting bolt 31 guides the reinforcing shaft 21 to approach the sliding sleeve 30 and is embedded in the recess of the sliding sleeve 30, so that the reinforcing shaft 21 becomes a supporting structure for the sliding sleeve 30 and the ball nut 20, thereby improving the supporting strength of the floor expansion joint bracket, so that the floor expansion joint bracket can be more easily adapted to heavier expansion joint products and thicker concrete pouring construction.

[0046] By relying on the rotation of the adjusting bolt 31, the reinforcing shaft 21 can be easily moved to become a supporting structure for the sliding sleeve 30 and the ball nut 20. In addition, compared with using a larger-sized adjusting bolt 31 to achieve the same supporting strength, less material is used. In addition, installing a larger-sized adjusting bolt 31 will be more difficult and will also generate a greater clamping force, which is easy to compress the thinner sliding sleeve 30 to deform.

[0047] Specifically, Figure 3 As shown, the reinforcing shaft 21 is a triangular, quadrilateral, pentagonal or hexagonal structure.

[0048] Specifically, the reinforcement shaft 21 is made of carbon steel material.

[0049] Specifically, Figure 2 As shown, a vertical platform 13 is provided at the bottom of the stand 10, and the vertical platform 13 is provided with a vertical bolt 14. By turning the vertical bolt 14 on the vertical platform 13, the extension length of the vertical bolt 14 can be controlled. Since the vertical bolt 14 is against the lower side of the expansion joint product, the verticality of the expansion joint product can be adjusted by controlling the extension length of the vertical bolt 14, thereby ensuring the quality of the final construction.

[0050] Specifically, Figure 4 , Figure 5 As shown, the end surface of the ball nut 20 exposed to the open groove 11 is plugged with a positioning platform 22 , and a positioning block 32 is welded on the inner side of the sliding sleeve 30 , and the positioning block 32 is embedded in the notch of the positioning platform 22 .

[0051] The sliding sleeve 30 is mounted on the stand 10 , and the positioning block 32 is engaged with the positioning platform 22 , which can improve the support strength of the ball nut 20 and the sliding sleeve 30 on the one hand, and position the ball nut and the sliding sleeve 30 on the other hand, so as to better install the adjusting bolt 31 .

[0052] More specifically, the positioning platform 22 is perpendicular to the ball nut 20 , and the positioning block 32 is perpendicular to the sliding sleeve 30 .

[0053] Specifically, Figure 2 As shown, the upper end of the adjusting screw rod 12 is exposed above the stand 10 , and a nut is installed on the exposed portion of the upper end of the adjusting screw rod 12 .

[0054] Specifically, Figure 2 As shown, the elevation assembly 40 is provided with an elevation support rod 41 , and the elevation support rod 41 is capable of moving laterally in a sleeve of the elevation assembly 40 .

[0055] More specifically, if Figure 2 , Figure 4 As shown, a support rod is provided at the bottom of the sleeve of the elevation component 40, and the support rod is connected to the stand 10.

[0056] More specifically, if Figure 6 As shown, the elevation support rod 41 located in the casing is provided with a tapered hole connected to the tapered hole on the casing side, and the tapered locking shaft 42 provided with the elevation component 40 is inserted into the tapered hole of the elevation support rod 41 and the tapered hole of the casing.

[0057] The lock shaft 42 is provided with a pressing plate 43 to press on the sleeve, and a baffle 44 is fixed to the side end of the sleeve. The baffle 44 abuts against the pressing plate 43 to limit the movement of the lock shaft 42.

[0058] By inserting the locking shaft 42 into the tapered hole of the high support rod and the tapered hole of the sleeve, not only the connection speed is fast, but also the cooperation of the tapered structure can achieve a tighter contact.

[0059] The pressing plate 43 that moves laterally with the locking shaft 42 only needs to be rotated into the groove between the baffle plate 44 and the pipe sleeve to limit the movement of the locking shaft 42, so as to complete a quick fixed installation.

[0060] Although the above describes the illustrative specific embodiments of the present invention so that those skilled in the art can understand the present invention, the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, all inventions and creations using the concepts of the present invention are protected.
