Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a combined ultra-long cement strip internal support. Background Art

[0002] A wall beam refers to a combined stress-bearing member composed of a reinforced concrete corbel and a masonry wall within the calculated height range above the beam. It is divided into several types such as simply supported wall beams, continuous wall beams, and framed-supported wall beams. When designing, the contribution of the wall above the reinforced concrete corbel to the bearing capacity of the corbel and the beneficial effect of stiffness should be considered. In actual projects, the stress of the reinforced concrete corbel calculated as a wall beam is similar to that of an eccentrically tensioned member, and its reinforcement is less than that of the corbel without considering the effect of the wall.

[0003] In order to ensure the cross-sectional dimensions of the beam wall, carpenters use tie bolts and cement support strips for external tension and internal support. However, for some particularly wide and thick wall beams, due to the limited strength, cost, and actual use of the cement strips, if the width of the common cement strip is too long, it is prone to breakage. If the cross-sectional dimensions are increased, the weight will increase greatly, making it difficult to use, and the cost will also increase accordingly, unable to meet the usage requirements. Therefore, in view of this, a combined ultra-long cement strip internal support is provided. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a combined ultra-long cement strip internal support.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A combined ultra-long cement strip internal support includes a floor. On one side of the upper surface of the floor, a wall beam inner formwork is fixedly connected. On the other side of the upper surface of the floor, a wall beam outer formwork is fixedly connected. On one side of the opposite sides of the wall beam inner formwork and the wall beam outer formwork, two cement counter braces are fixedly connected. A limiting slot is opened on one side of the cement counter brace, and a first limiting connection block is inserted into the limiting slot. On one side of the first limiting connection block, a horizontally placed first support steel bar is fixedly connected. The other end of the first support steel bar is fixedly connected to a first fixing plate. On one side of the first fixing plate, an adjustable-length adjusting structure is fixedly connected. The first support steel bar and the adjusting structure are used to support the wall beam inner formwork and the wall beam outer formwork.

[0007] As a further improvement of the utility model, the adjusting structure includes two bottom rods fixedly connected to one side of the first fixing plate. An adjusting rod is movably connected inside each of the two bottom rods. The other ends of the two adjusting rods are fixedly connected to the same second fixing plate. On one side of the second fixing plate, a second support steel bar is fixedly connected.

[0008] As a further improvement of the present utility model, a mounting plate is fixedly connected between the two bottom rods. Threaded holes are provided on one side of the second fixing plate and the second support reinforcing bar, and one side of the mounting plate is rotatably connected with a threaded rod adapted to the threaded holes.

[0009] As a further improvement of the present utility model, a nut is fixedly connected to one end of the threaded rod.

[0010] As a further improvement of the present utility model, a second limit connection block is fixedly connected to the other end of the second support reinforcing bar.

[0011] As a further improvement of the present utility model, a positioning and reinforcing rod is fixedly connected between the two cement counter braces.

[0012] Advantages of the present utility model:

[0013] By providing the cement counter braces, during use, the whole cement inner brace is changed to a segmented cement inner brace. The segmented cement inner brace is composed of cement counter braces at both ends. The cement counter braces are built into the opposite sides of the inner formwork and the outer formwork of the wall beam and calibrated, and are connected through the limit slots. The cross-sectional dimensions of the cement counter braces are the same as those of the commonly used cement inner brace strips, and there is no need to frequently replace materials according to the thickness of the wall beam, so that the device avoids the fracture of the cement strip due to excessive width, and at the same time reduces the total amount of mortar of the cement inner brace strip, effectively reducing costs and increasing the practicability of the device.

[0014] By providing the adjusting structure, during use, the first limit connection block is inserted into one of the cement counter braces, and the threaded rod is driven to rotate by the nut, so that the second fixing plate and the second support reinforcing bar move towards the other cement counter brace through the limit of the adjusting rod, and at the same time the adjusting rod moves in the bottom rod until the second limit connection block is inserted into the limit slot of the other cement counter brace to complete the connection, enabling the device to simply adjust the length and thus support the inner formwork and the outer formwork of the wall beam at different distances.

[0015] By providing the cement counter braces in the present utility model, the contact area between the first support reinforcing bar and the second support reinforcing bar can be effectively increased, avoiding the inner formwork and the outer formwork of the wall beam from being penetrated due to too small contact area, and at the same time preventing the first support reinforcing bar and the second support reinforcing bar from touching the inner formwork and the outer formwork of the wall beam at both ends to form a water seepage path, increasing the safety of the device.
