Description

Technical Field

[0001] This application relates to the field of hollow floor slabs, and more particularly to a fixing structure for a hollow floor slab core mold. Background Technology

[0002] During the pouring of the floor slab, a steel reinforcement frame must first be erected. Then, multiple hollow floor slab core molds are fixed within the steel reinforcement frame. Finally, cement mortar is poured, submerging the steel reinforcement frame and the hollow floor slab core molds, and then solidifies. After the cement mortar and steel reinforcement frame solidify, a reinforced concrete structure is formed. The hollow floor slab core molds are located within the reinforced concrete structure. The floor slab formed at this stage is relatively lightweight, has good structural strength, and is suitable for various usage environments.

[0003] The existing core mold fixing structure includes steel bars, which are horizontally arranged to form a frame structure. The steel bars are fixed to the side wall of the core mold by snap-fit, so that the core mold can be fixed between the steel bars and poured.

[0004] The aforementioned technical solutions have the following defects: when cement mortar is poured in and submerges the reinforcing bars and core mold, the core mold has a low density and is easily subjected to buoyancy in the cement mortar, causing the core mold to float in the vertical and horizontal directions, resulting in poor core mold positioning and poor quality and strength of the formed floor slab. Utility Model Content

[0005] To reduce the likelihood of the core mold floating and moving during casting, this application provides a fixing structure for a hollow floor slab core mold.

[0006] The fixing structure for a hollow floor slab core mold provided in this application adopts the following technical solution:

[0007] A fixing structure for a hollow floor slab core mold includes angle steel, connecting rods, and reinforcing bars. The angle steel is horizontally arranged on opposite sides of the core mold. The connecting rod is horizontally arranged and passes through the angle steel. A protruding piece is provided on the middle side wall of the core mold. The protruding piece is horizontally arranged. Angle steel is provided on both the upper and lower sides of the protruding piece. The reinforcing bars are vertically arranged and pass through the angle steel. The reinforcing bars are used to connect the angle steel on the upper and lower sides of the protruding piece.

[0008] By adopting the above technical solution, by setting a connecting rod on the angle steel, allowing the connecting rod to pass through the angle steel and setting a nut on the connecting rod, the two angle steels on the connecting rod can clamp the two sides of the core mold. The angle steel and the connecting rod are perpendicular to each other, and the connecting rod and the angle steel can together form a frame structure to clamp the core mold. By setting angle steel on the upper and lower sides of the protruding piece, the angle steel can jointly hold the protruding piece, which can reduce the probability of the core mold floating vertically or horizontally in the cement mortar.

[0009] Optionally, the reinforcing bars are welded and fixed to the angle steel.

[0010] By adopting the above technical solution, and by welding and fixing the reinforcing bars to the angle steel, and by vertically setting the reinforcing bars and connecting the two angle steels on the upper and lower sides of the protruding piece, the angle steel can stably clamp the protruding piece, reducing the probability of the core mold shaking and shifting during the cement mortar solidification process.

[0011] Optionally, the mandrel is configured as a plurality of mandrels, which are arranged at intervals along the length of the angle steel.

[0012] By adopting the above technical solution, multiple core molds are set between two angle steels and arranged along the length of the angle steels, so that multiple core molds can be fixed and poured into reinforced concrete.

[0013] Optionally, the angle steel has a waist hole, the length direction of which is parallel to the length direction of the angle steel, and the connecting rod is set in the waist hole.

[0014] By adopting the above technical solution, by opening a waist hole in the angle steel, the connecting rod is inserted into the waist hole, which makes it convenient for the user to adjust the position of the connecting rod on the angle steel, so that the two connecting rods can clamp the core mold of different sizes.

[0015] Optionally, a spring is provided in the waist hole, with the length direction of the spring parallel to the length direction of the waist hole. One end of the spring is fixed to the inner wall of the waist hole, and the other end abuts against the connecting rod.

[0016] By adopting the above technical solution, a spring is installed in the waist hole, and the spring abuts against the connecting rod. When a core mold is set between the two connecting rods, the spring keeps the connecting rod abutting against the core mold, reducing the probability of the connecting rod sliding in the waist hole and detaching from the core mold.

[0017] Optionally, a baffle is welded and fixed to the angle steel, and the baffle is arranged on both sides of the spring.

[0018] By adopting the above technical solution, by setting a baffle on the angle steel, the baffle can block the spring, thereby making it difficult for the end of the spring to detach from the waist hole, so that the spring can always abut against the connecting rod and apply a spring force parallel to the length direction of the angle steel to the connecting rod.

[0019] Optionally, the connecting rod includes a crossbar, two mounting blocks, and two bolts. The two ends of the crossbar are connected to the two mounting blocks respectively, and the bolts pass through the mounting blocks and are threadedly connected to the mounting blocks. The length direction of the bolts is parallel to the crossbar.

[0020] By adopting the above technical solution, mounting blocks are set at both ends of the crossbar, and bolts are set on each mounting block. By tightening the bolts, the ends of the bolts can be made to abut against the angle steel, thereby achieving the effect of connecting the connecting rod to the two angle steels. This allows the two angle steels to clamp the core mold, achieving the effect of fixing the core mold. This makes it convenient for users to fix core molds of different sizes, reduces the steps of processing holes in the angle steel, and improves construction efficiency.

[0021] Optionally, the bolt end is provided with a friction element made of a rough-surfaced elastic material, which is used to abut against the angle steel.

[0022] By adopting the above technical solution, and by setting friction elements at the ends of the bolts, the bolts and angle steels can abut against each other through the friction elements, thereby increasing the friction between the bolts and angle steels and improving the connection stability of the connecting rods.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By setting a connecting rod on the angle steel, with the connecting rod passing through the angle steel and a nut on the connecting rod, the two angle steels on the connecting rod can clamp the two sides of the core mold. The angle steel and the connecting rod are perpendicular to each other. The connecting rod and the angle steel can together form a frame structure to clamp the core mold. By setting angle steel on the upper and lower sides of the protruding piece, the angle steel can jointly hold the protruding piece, which can reduce the probability of the core mold floating vertically or horizontally in the cement mortar.

[0025] 2. By opening a waist hole in the angle steel, the connecting rod can be inserted into the waist hole, which makes it convenient for the user to adjust the position of the connecting rod on the angle steel, so that the two connecting rods can clamp mandrels of different sizes;

[0026] 3. By setting a spring in the waist hole, the spring abuts against the connecting rod. When a mandrel is set between the two connecting rods, the spring keeps the connecting rod abutting against the mandrel, reducing the chance of the connecting rod sliding in the waist hole and disengaging from the mandrel.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a fixing structure for a hollow floor slab core mold, referring to... Figure 1 The system includes angle steel 1, connecting rod 2, and reinforcing bar 3. The cross-section of angle steel 1 is right-angled. Angle steel 1 abuts against one side of the core mold 4. Connecting rod 2 is horizontally set and passes through angle steel 1. Reinforcing bar 3 is vertically set and passes through angle steel 1. By setting angle steel 1 and connecting rod 2 vertically, the user can clamp angle steel 1 and connecting rod 2 onto the side wall of core mold 4. This allows multiple angle steels 1 and multiple connecting rods 2 to surround and clamp core mold 4. When pouring cement mortar, this reduces the probability of core mold 4 floating and moving horizontally in the cement mortar, thus ensuring that core mold 4 is positioned in the predetermined position in the cement mortar. After the cement mortar solidifies, the pouring quality of the floor slab is better.

[0034] Reference Figure 1 The core mold 4 has a protruding piece 41 in the middle, which is horizontally positioned. Angle steel 1 is provided on both the upper and lower sides of the protruding piece 41. The angle steel 1 is used to jointly hold the protruding piece 41, thereby reducing the probability of the core mold 4 floating up and down in the cement mortar. The reinforcing bar 3 is vertically positioned and passes through the angle steel 1 on the upper and lower sides of the protruding piece 41. The reinforcing bar 3 is welded and fixed to the angle steel 1, thereby improving the connection strength of the angle steel 1 on the upper and lower sides of the protruding piece 41.

[0035] Reference Figure 1 The connecting rod 2 is horizontally set and passes through the angle steel 1. The connecting rod 2 can be a screw rod. The end of the connecting rod 2 is provided with a nut 21. The nut 21 abuts against the angle steel 1, so that the angle steel 1 on both sides of the core mold 4 can clamp the core mold 4.

[0036] Reference Figure 2 Multiple core molds 4 are set between two angle steels 1. The core molds 4 are arranged at intervals along the length of the angle steel 1. By inserting multiple connecting rods 2 into the angle steel 1, the core molds 4 can be set in the space between two adjacent connecting rods 2, so that multiple core molds 4 can be arranged and cast.

[0037] Reference Figure 3In other embodiments, the angle steel 1 is provided with a waist hole 11, the length direction of the waist hole 11 is parallel to the length direction of the angle steel 1, and the connecting rod 2 is provided in the waist hole 11. By moving the connecting rod 2, the user can make the connecting rod 2 abut against the outer wall of the core mold 4 of different sizes, which makes it convenient for the user to fix the core mold 4 of different sizes.

[0038] Reference Figure 3 A spring 12 is installed inside the waist hole 11. The length direction of the spring 12 is parallel to the length direction of the waist hole 11. One end of the spring 12 is fixed to the inner wall of the waist hole 11, and the other end abuts against the connecting rod 2. The spring 12 is used to abut against the connecting rod 2, so that the connecting rod 2 always abuts against the outer wall of the core mold 4, thereby improving the connection stability of the connecting rod 2 and the core mold 4 and reducing the probability of the connecting rod 2 sliding in the waist hole 11 and the core mold 4 disengaging from the connecting rod 2. A baffle 13 is welded and fixed to the angle steel 1. The baffle 13 covers the end of the waist hole 11 and is set on both sides of the angle steel 1. By setting the baffle 13 on both sides of the spring 12, the probability of the spring 12 coming out of the waist hole 11 can be reduced, and the connection stability of the spring 12 in the waist hole 11 can be improved.

[0039] Reference Figure 4 In other embodiments, the connecting rod 2 includes a crossbar 22, two mounting blocks 23, and two bolts 24. The two ends of the crossbar 22 are fixedly connected to the mounting blocks 23, and the bolts 24 pass through the mounting blocks 23 and are threadedly connected to them. The length direction of the crossbar 22 is parallel to the length direction of the bolts 24. By using the bolts 24 to abut against the angle steel 1, the user can connect the connecting rod 2 between the two angle steels 1, thereby enabling the two angle steels 1 to stably clamp the mandrel 4. A friction element 25 is provided at the end of the bolt 24. The friction element 25 can be made of a rough-surfaced rubber material. The friction element 25 is positioned between the angle steel 1 and the bolt 24, further reducing the probability of the bolt 24 slipping off the angle steel 1.

[0040] The implementation principle of this application embodiment is as follows: by setting angle steel 1 and connecting rod 2 on the outside of the core mold 4, the angle steel 1 and connecting rod 2 are assembled together to form a frame structure and are snapped into the core mold 4, which can keep the core mold 4 fixed in the cement mortar and reduce the probability of the core mold 4 floating up and down and moving left and right in the cement mortar. By making the connecting rod 2 and angle steel 1 detachably connected, it is convenient for the user to move the position of the connecting rod 2 on the angle steel 1, so that the connecting rod 2 can clamp core molds 4 of different sizes.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
