Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of roof construction technology, and more specifically, to a pre-installation device for roof concrete surface layer segmentation joints. Background Technology
[0002] The roof surface layer refers to the part above the roof structural slab, including the leveling layer, insulation layer, waterproofing layer, rigid protective layer, and finishing layer. Expansion joints are pre-installed joints in the leveling layer, rigid waterproofing layer, and rigid protective layer to reduce cracking. The rigid protective layer only has V-shaped grooves on its surface; these are called surface expansion joints. Setting a certain number of expansion joints reduces the area of individual concrete layers, thereby reducing deformation due to expansion, contraction, and warping, effectively preventing and limiting crack formation.
[0003] Existing pre-installation devices involve placing pre-installation components on the roof, assembling multiple sets of pre-installation components using splicing components, and then covering the pre-installation components with concrete pouring. However, this device is difficult to adjust according to needs during installation, which affects the subsequent construction work of operators.
[0004] The aforementioned pre-installed device is difficult to adjust according to needs, which affects the subsequent construction work of the operators and reduces the effectiveness of the device. Utility Model Content
[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a pre-installation device for roof concrete surface layer joints, which solves the technical problem that the device in the prior art is difficult to adjust according to needs, thus affecting the subsequent construction of operators.
[0006] According to one aspect, at least one embodiment of this disclosure provides a pre-installation device for the expansion joints of a roof concrete surface layer, which includes an injection box, and further includes an installation piece, an adjustment block, an expansion joint frame, a connecting piece, a support rod, a fixing rod, a movable tube, a plug-in block, and a connecting tube;
[0007] The mounting piece is slidably connected to the glue injection box. An adjusting block is slidably connected inside the mounting piece.

The insertion block is slidably connected to the inside of the glue injection box. The connecting tube passes through the inside of the glue injection box. The outer surface of the connecting tube passes through the inside of the mounting piece.
[0008] As a preferred embodiment of the pre-installation device for the roof concrete surface layer segmentation joint described in this utility model, in order to facilitate the operator to observe the glue injection inside the segmentation joint frame, a support plate is installed inside the segmentation joint frame, and an upper cover is slidably connected inside the segmentation joint frame, with auxiliary holes provided on the upper surface of the upper cover.

[0010] As a preferred embodiment of the pre-installation device for the roof concrete surface layer segmentation joints described in this utility model, in order to improve the smoothness of adjusting the device, a first connecting plate is slidably connected inside the first connecting groove, and a lower block is installed on the upper surface of the first connecting plate.
[0011] As a preferred embodiment of the pre-installation device for the roof concrete surface layer segmentation joint of this utility model, in order to facilitate the operator to fix the lower block, the lower block is provided with a plug-in column, the top of the plug-in column is installed with an upper block, and both the upper block and the lower block are provided with placement grooves.
[0012] As a preferred embodiment of the pre-installation device for the roof concrete surface layer segmentation joint described in this utility model, in order to make it easier for operators to adjust the position of the upper block according to their needs, a second connecting plate is installed on the side of the upper block, and a second connecting groove is provided inside the adjustment frame.
[0013] As a preferred embodiment of the pre-installation device for the roof concrete surface layer segmentation joint of this utility model, in order to speed up the operator's adjustment of the position of the upper block, the second connecting plate is slidably connected to the second connecting groove, and a lifting plate is installed inside the upper block.
[0014] As a preferred embodiment of the pre-installation device for the roof concrete surface layer segmentation joint described in this utility model, in order to better remove the lower layer block according to the requirements, a lifting column is installed on the upper surface of the lifting plate, the outer surface of the lifting column penetrates through the adjustment frame, and a lifting plate is installed at the top of the lifting column.
[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] In this disclosure, the dividing joint frame is moved outward along the mounting plate by manipulating the adjusting block, thereby adjusting the dividing joint frame outward. Compared with the prior art, which is difficult to adjust according to needs, this device can adjust the width of the dividing joint according to needs, avoiding the situation of concrete flowing to each other during construction and reducing the impact on the stability of the concrete after it has set.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0031] like Figures 1-5As shown, it illustrates a pre-installation device for roof concrete surface layer segmentation joints in one embodiment of the present disclosure, which includes an injection box 1, an installation piece 2, an adjustment block 3, a segmentation joint frame 4, a connecting piece 5, a support rod 6, a fixing rod 7, a moving tube 8, a plug-in block 9, and a connecting tube 10.
[0032] like Figure 3 As shown, the mounting piece 2 is slidably connected to the glue injection box 1. After the mounting piece 2 slides into the glue injection box 1, it is fixed by external bolts. An adjusting block 3 is slidably connected inside the mounting piece 2. A dividing seam frame 4 is installed on the side of the adjusting block 3. A connecting piece 5 is installed inside the dividing seam frame 4. A support rod 6 is installed on the side of the connecting piece 5. A fixing rod 7 is installed at the end of the support rod 6 away from the connecting piece 5. A moving tube 8 is threaded onto the outer surface of the fixing rod 7. A plug-in block 9 is rotatably connected to the outer end of the moving tube 8. The plug-in block 9 passes through the inside of the dividing seam frame 4 and is slidably connected to the inside of the glue injection box 1. A connecting tube 10 passes through the inside of the glue injection box 1. Multiple sets of plug-in slots are opened inside the glue injection box 1. Figure 3 The outer surface of the connecting tube 10 penetrates the interior of the mounting plate 2 in the central insertion slot. A support plate 11 is installed inside the partition frame 4. An upper cover 12 is slidably connected inside the partition frame 4. An auxiliary hole 13 is provided on the upper surface of the upper cover 12. After the upper cover 12 slides into the partition frame 4, it is blocked by the support plate 11. The function of the auxiliary hole 13 is to assist the operator in removing the upper cover 12 from the partition frame 4.
[0033] like Figure 4 As shown, an adjustment frame 14 is installed on the side of the dividing frame 4. A first connecting groove 15 is provided inside the adjustment frame 14. A first connecting plate 16 is slidably connected inside the first connecting groove 15. A lower block 17 is installed on the upper surface of the first connecting plate 16. A connecting post 18 passes through the lower block 17. An upper block 19 is installed at the top of the connecting post 18. The length of the connecting post 18 is equal to the distance between the upper block 19 and the adjustment frame 14. That is, after the upper surface of the upper block 19 contacts the inner top wall of the adjustment frame 14, the connecting post 18 is just pulled out of the lower block 17. The subsequent removal of the lower block 17... The middle insertion post 18 will not cause obstruction. The upper block 19 and the lower block 17 are both provided with placement slots 20. The side of the upper block 19 is equipped with a second connecting plate 21. The inside of the adjustment frame 14 is provided with a second connecting slot 22. The second connecting plate 21 and the second connecting slot 22 are slidably connected. The inside of the upper block 19 is equipped with a lifting plate 23. The lifting plate 23 is inverted T-shaped, so it will not slide out of the upper block 19 during the upward movement of the lifting plate 23. The upper surface of the lifting plate 23 is equipped with a lifting post 24. The outer surface of the lifting post 24 penetrates the inside of the adjustment frame 14. The top of the lifting post 24 is equipped with a lifting piece 25.
[0034] In this embodiment, as Figure 1 and Figure 2 As shown, the upper surface of the glue injection box 1 is connected to the glue injection tube 26, and the inside of the placement groove 20 is equipped with a reinforcing skeleton 27. The reinforcing skeleton 27 is composed of horizontal and vertical steel bars evenly arranged. The horizontal and vertical steel bars are tied together by iron wire in a cross shape. The number of horizontal and vertical steel bars can be increased or decreased according to the construction requirements. In this process, the number of lower block 17 needs to be increased or decreased first.
[0035] It should be noted that the number of glue injection boxes 1 is not just one set. During the assembly of this device, there are multiple sets of glue injection boxes 1. Each set of glue injection boxes 1 has mounting pieces 2 connected to its four sides, so that the device forms a complete segmentation joint after assembly and pouring.
[0036] In this embodiment, the mounting piece 2 is slid into the glue injection box 1 and fixed to the glue injection box 1 by external bolts. The upper cover 12 is slid out from the inside of the partition frame 4 by manipulating the auxiliary hole 13, so that the upper cover 12 is detached from the upper surface of the support piece 11. The moving tube 8 is rotated counterclockwise, and the moving tube 8 moves outward along the fixed rod 7. The moving tube 8 rotates inside the insertion block 9 and drives the insertion block 9 to move outward. The insertion block 9 moves outward along the inside of the partition frame 4 and slides out of the insertion groove located in the middle. The two sets of partition frames 4 are then adjusted. The segment 3 moves outward along the mounting plate 2, and the segment joint frame 4 moves outward, driving the adjustment frame 14 to move outward. The adjustment frame 14 moves outward to reduce the length of the transverse and longitudinal steel bars in the reinforcing skeleton 27. After adjustment, the moving pipe 8 is rotated clockwise, so that the moving pipe 8 moves inward along the fixed rod 7, driving the plug block 9 to move inward. The plug block 9 moves inward and slides into the corresponding plug groove, adjusting the size of the segment joint after pouring, preventing the pouring concrete from flowing to each other due to difficulty in adjusting the size of the segment joint, and reducing the impact on maintaining the stability of the concrete after pouring.
[0037] Based on the number of steel bars inside the reinforcing frame 27, the number of lower blocks 17 is increased or decreased. The reinforcing frame 27 is placed in the placement slot 20 at the bottom. The lifting plate 25 is moved upward, causing the lifting column 24 to move upward. The lifting column 24 moves upward, causing the lifting plate 23 to move upward. The lifting plate 23 moves upward, causing the upper block 19 to move upward. The upper block 19 moves upward, causing the second connecting plate 21 to move upward. The second connecting plate 21 moves upward along the second connecting slot 22. The upper block 19 moves upward, causing the insertion column 18 to move upward. The lower block 17 is manipulated to slide the first connecting plate 16 along the first connecting slot 15, so that the lower block 17 carries the reinforcing frame 27 into the interior of the adjustment frame 14.
[0038] After the lower block 17 moves to the corresponding upper block 19 and is lowered, the lifting plate 25 is released, causing the lifting plate 23 to move downward due to gravity. The downward movement of the lifting plate 23 causes the lifting column 24 to move downward, and the downward movement of the lifting column 24 causes the lifting plate 25 to move downward. The downward movement of the lifting plate 25 contacts the adjustment frame 14, and the downward movement of the lifting plate 23 causes the upper block 19 to move downward. The downward movement of the upper block 19 causes the second connecting plate 21 to move downward along the second connecting groove 22. The downward movement of the upper block 19 causes the insertion post 18 to move downward. The insertion post 18 moves downward and inserts into the lower block 17, so that the upper block 19 contacts the lower block 17, and the reinforcing frame 27 enters the placement groove 20 located at the top.
[0039] After the splicing is completed, the adhesive is injected into the adhesive box 1 along the adhesive injection tube 26. The adhesive is then transferred to the partition frame 4 through the connecting tube 10. After the adhesive is injected, concrete is poured to reinforce the skeleton 27. The concrete surface is flush with the upper surface of the upper cover 12, so that the multiple partition frames 4 enclose the concrete into groups of squares.
[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
